Description

[Technical Field]

[0001] The present invention relates to a pipe support stand for supporting pipes on a roof. [Background technology]

[0002] Piping installation work on the rooftops of concrete buildings such as apartment buildings involves fixing pipes onto multiple concrete equipment foundations. The pipes installed on the rooftop are large diameter pipes such as water supply pipes, chimney pipes, and connecting water supply pipes, and each pipe support is long, at approximately 6m, so the pipe support installed on the roof must be able to withstand large wind loads. Conventionally, a steel support frame with a U-shaped cross section is fixed to the equipment foundation with anchors, and the pipes are directly fixed to the support frame with U-bolts. Such pipe supports are disclosed in Patent Documents 1 and 2, for example. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-065838 [Patent Document 2] Japanese Patent Application Publication No. 10-061831 Summary of the Invention [Problem to be solved by the invention]

[0004] FIG. 1 is an explanatory diagram of a conventional pipe support 100 that is installed on an equipment foundation P on a roof. FIG. 1(A) is a side view when the pipe H has a slope. FIG. 1(B) is a side view when a spacer 108 is inserted between the support frame 103 and the equipment foundation P. FIG. 1(C) is a side view of a post-installed anchor 109. The post-installed anchor 109 is used to fix the underside of the support frame 103 to the concrete equipment foundation P. FIG. 1(D) is a side view when the spacer 108 is inserted between the support frame 103 and the pipe H. FIG. 1(E) is a view taken along the arrow AA in FIG. 1(D). In this figure, H represents piping, 100 represents a conventional piping support, 103 represents a support frame, 107 represents a U-bolt, 108 represents a spacer, 109 represents a post-installed anchor, and P represents a concrete equipment foundation.

[0005] When a slope is applied to the pipe H, the height at which the pipe H is supported must be changed for each equipment foundation P. To achieve this, the pipe H is first temporarily fixed at a slope on-site, the height required for the support frame 103 for each equipment foundation P is measured and recorded, and a support frame 103 with a different height is custom-ordered for each equipment foundation P. After receiving the support frame 103, the worker must return to the site, remove the temporarily fixed pipe H, install the received support frame 103, and fix the pipe H again while frequently checking the slope, which is a double process. As such, when laying a sloped pipe H, a lot of work is required, including the time required to temporarily fix the pipe H, the time required to measure and record the height required for the support frame 103, and the time required to arrange for support frames 103 with different heights. Furthermore, construction errors occur in the level accuracy (height accuracy) of the top of the concrete equipment foundation P. Therefore, when laying the pipes horizontally, it is necessary to adjust the height of the pipes H while frequently checking with a spirit level whether the pipes H are horizontal for each equipment foundation P, and selecting and installing the type of spacer 108 is time-consuming.

[0006] Specifically, first, the height of each equipment foundation P is measured on-site to calculate the height of the spacers 108 required, and the required type of spacers 108 is prepared. If the construction error is a few millimeters, the height can be adjusted by inserting spacers 108 between the support frame 103 and the equipment foundation P, as shown in Figure 1(B). In this case, loosen nut 109b in Figure 1(C), insert spacers 108 between the support frame 103 and the equipment foundation P, and then lift the support frame 103. However, with this method, the height of the spacer 108 inserted under the support frame 103 is limited by the length of the threaded portion 109a of the post-installed anchor 109. In other words, the support frame 103 can only be raised up to a range of several millimeters until the nut 109b of the post-installed anchor 109 reaches the upper end of the threaded portion 109a.

[0007] If it is desired to raise the support frame 103 to a height greater than this, a spacer 108 is inserted between the pipe H and the support frame 103, as shown in Figures 1(D) and 1(E). This spacer 108 has a recess along the side of the pipe H, and the pipe H is fitted into this recess to stabilize the pipe H. Therefore, when laying the pipe H, it was necessary to determine how many and what type of spacers 108 were required from the measured values ​​of each facility foundation P, and then to take the time to order them.

[0008] Next, the height of the pipe H is adjusted by inserting the various spacers 108 prepared above or below the support frame 103. At this time, fine adjustments must be made while repeatedly checking the level (horizontal state) of the pipe H with a spirit level. In this way, the construction work to lay the pipe H horizontally also took a lot of time and effort. Therefore, the construction of pipe H was extremely time-consuming, whether it was laid horizontally or at an incline. As a result, the construction costs for the construction of pipe H were high due to the high labor costs.

[0009] The present invention has been devised to solve the above-mentioned problems, and an object of the present invention is to provide a pipe support base that can reduce the effort required to adjust the height of pipes laid above the installation position on the roof. [Means for solving the problem]

[0010] According to the present invention, there is provided a pipe support base for supporting pipes, comprising: A base material and A receiving material that can be attached to the base material at different positions in the vertical direction; a fastener having a shaft portion that penetrates the base material and the receiving material and connects the base material and the receiving material; a displacement prevention piece having an axial hole through which the axial portion passes, the base member has a base-side flat plate portion extending in the up-down direction, The receiving member has a receiving-side flat plate portion extending in the up-down direction, The base-side flat plate portion and the receiving-side flat plate portion are connected to the fastener by passing the shank through them in a state where they are overlapped with each other, one of the base-side flat plate portion and the receiving-side flat plate portion has a continuous hole formed by a plurality of connected holes and through which the shaft portion passes; the other of the base-side flat plate portion and the receiving-side flat plate portion has a through-hole through which the shaft portion passes, The minimum width of the continuous hole is greater than the diameter of the shaft portion; the plurality of holes are formed at different positions in the up-down direction, Each of the plurality of holes is a positioning hole formed so that at least a part of the outer periphery of the displacement prevention piece can be fitted therein, A piping support base is provided in which the anti-slip piece fits into the positioning hole with the shaft portion passing through the shaft hole when the fastener connects the base side flat plate portion and the receiving side flat plate portion. [Effects of the Invention]

[0011] According to the present invention, the base-side flat plate portion of the base material and the receiving-side flat plate portion of the receiving material are overlapped and connected by a fastener through a shaft portion. The continuous hole formed in one of the base-side flat plate portion and the receiving-side flat plate portion is shaped to connect multiple positioning holes formed at different positions in the vertical direction, and the minimum width of the continuous hole is set to be larger than the diameter of the shaft. With this configuration, the pipe support of the present invention can be passed between the multiple positioning holes while the shaft portion is inserted into the continuous hole. Therefore, the pipe support of the present invention can reduce the number of times the shank of the fastener needs to be inserted and removed by the number of boundaries between the positioning holes.

[0012] In addition, in the pipe support of the present invention, the anti-slip piece has an axial hole through which the shank of the fastener passes, and the positioning hole is formed so that at least a portion of the outer periphery of the anti-slip piece can be fitted. With this configuration, the pipe support of the present invention can fit the anti-slip pieces into the positioning holes of the continuous holes while the shaft portion is inserted through the shaft hole. Also, with the pipe support of the present invention, at least a portion of the outer periphery of the anti-slip pieces can fit into the positioning holes, so that the anti-slip pieces fitted into the continuous holes can be prevented from moving to other positioning holes. Therefore, the piping support base of the present invention has an anti-slip piece that fills the gap between the peripheral surface of the shaft portion and the continuous hole, thereby preventing the position of the shaft portion relative to the base side flat plate portion or receiving side flat plate portion in which the continuous hole is provided from shifting in the in-plane direction of the base side flat plate portion or receiving side flat plate portion.

[0013] In this way, the piping support stand of the present invention reduces the effort required for adjusting the height of the piping by allowing the fastener shaft to remain inserted into the continuous hole and slide between the positioning holes, and after the work is completed, the anti-slip piece prevents the fastener from shifting in the in-plane direction of the base side flat plate portion or receiving side flat plate portion in which the continuous hole is provided. Therefore, the pipe support of the present invention does not require spacers or multiple support frames of different heights, which reduces the amount of work required for installation. Furthermore, by using the pipe support of the present invention, the time required for adjusting the height of the pipes can be reduced, which saves labor and reduces the cost of facility construction.

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In addition, common parts in the drawings are given the same reference numerals, and duplicated explanations will be omitted.

[0016] (First embodiment) Fig. 2 is a left side view of the pipe support 10 of the first embodiment when in use. Fig. 3 is a left side view of the pipe support 10 of the first embodiment when attached to an equipment foundation P of a different height. Fig. 3(A) shows the pipe support 10 when it is at its most extended height, and Fig. 3(B) shows the pipe support 10 when it is at its most retracted height. In the following figures, including Fig. 2 and Fig. 3, H represents the pipe, 10 represents the pipe support, and P represents the equipment foundation.

[0017] Hereinafter, "when the pipe support 10 is in use" will be simply referred to as "when in use." In addition, in the following description, the direction perpendicular to the left and right sides of the pipe support 10 will be referred to as the "side direction X." In this drawing, the side direction X is perpendicular to the paper surface. The right side of this drawing is the front side of the pipe support 10, and the left side of the drawing is the back side of the pipe support 10. Furthermore, in the following description, "upper during use" will be simply referred to as "upper," and "lower during use" will be simply referred to as "lower." For example, in the following description, "upper" included in words such as upper surface, upper part, upper end, upper and lower, means "upper during use." Similarly, in the following description, "lower" included in words such as lower, lower end, upper and lower, means "lower during use."

[0018] The pipe support 10 of this embodiment is a support for fixing a pipe H to the upper surface P1 of a concrete equipment foundation P installed on the roof of a concrete building such as an apartment building. The pipe support 10 includes a receiving material 20, a base material 30, and a fastener 2. The receiving material 20, the base material 30, and the fastener 2 are preferably all made of rust-resistant steel plates such as stainless steel or hot-dip galvanized steel.

[0019] The receiving member 20 and the base member 30 are both metal members having flat plate portions 22, 32 extending in the vertical direction Z. The flat plate portions 22, 32 each have a plane extending in the vertical direction Z. In the following description, the thickness direction of the flat plate portions 22, 32 will be simply referred to as the "thickness direction Y." The receiving material 20 and the base material 30 may be, for example, metal fittings or brackets that form an L-shape when viewed from the side, flat metal plates bent at right angles to form an L-shape, L-shaped steel, T-shaped steel, CT-shaped steel, C-shaped steel, or a combination thereof.

[0020] When the piping support base 10 is fixed to the equipment foundation P, the receiving material 20 is located on the upper side and the base material 30 is located on the lower side. The receiving material 20 is a metal member configured to be attachable to the base material 30 at different positions in the vertical direction Z. The receiving material 20 has a receiving-side flat plate portion 22 extending in the vertical direction Z, and a top plate portion 21 perpendicular to the receiving-side flat plate portion 22. When the pipe support base 10 is in use, the receiving material 20 is fixed with the top plate portion 21 facing up. In this case, the portion of the receiving-side flat plate portion 22 that contacts the top plate portion 21 becomes the upper end portion 22b of the receiving-side flat plate portion 22.

[0021] The pipe H is fixed to the top plate portion 21 with a U-bolt 7, with its side surface h placed on the upper surface 21a of the top plate portion 21. The pipe H may be fixed horizontally as shown by the solid line in FIG. 2, or may be fixed at an angle as shown by the two-dot chain line in FIG. 2.

[0022] The base material 30 has a bottom plate portion 31 that extends parallel to the upper surface P1 of the equipment foundation P when in use, and a base-side flat plate portion 32 that extends in the vertical direction Z perpendicular to the bottom plate portion 31. The base material 30 is a metal member that is directly fixed to the upper surface P1 of the equipment foundation P.

[0023] The receiving material 20 and the base material 30 are connected by the fastener 2 by passing the shaft portion 2b of the fastener 2 through the receiving side flat plate portion 22 and the base side flat plate portion 32 in a state where they are overlapped. For example, suppose both the receiving member 20 and the base member 30 are either metal fittings or brackets that are L-shaped when viewed from the side, metal flat plates bent at right angles to form an L shape, L-shaped steel, or C-shaped steel, or a combination thereof. In this case, as shown in Figure 2, it is preferable that the receiving-side flat plate portion 22 and the base-side flat plate portion 32 are connected so that the top plate portion 21 and the bottom plate portion 31 protrude parallel to each other in the same direction (to the left in this figure) from both ends of the pipe support 10 in the vertical direction Z. However, this is not limiting, and in this case, the top plate portion 21 and the bottom plate portion 31 may extend parallel to each other in opposite directions from the respective flat plate portions 22, 32. Furthermore, when the receiving material 20 or the base material 30 is a T-shaped steel or a CT-shaped steel, the top plate portion 21 or the bottom plate portion 31 may extend horizontally in both directions from the receiving side flat plate portion 22 or the base side flat plate portion 32.

[0024] The fastener 2 is a member that connects the base material 30 and the receiving material 20. The fastener 2 has a shaft 2b that passes through the base material 30 and the receiving material 20, a head 2a provided at one end of the shaft 2b, and a fastener 2c. The fastener 2 may be, for example, a bolt and a nut. In this case, the head of the bolt corresponds to the head 2a of the fastener 2, and the shank of the bolt corresponds to the shank 2b of the fastener 2. The nut corresponds to the fastener 2c of the fastener 2. For example, when a bolt and a nut are used as the fastener 2, the shank 2b of the bolt is passed through holes 5, 6 (not shown) opened in the overlapping receiving-side flat plate portion 22 and the base-side flat plate portion 32, and the receiving-side flat plate portion 22 and the base-side flat plate portion 32 are sandwiched between the nut threaded onto the shank 2b and the head 2a of the bolt, thereby connecting the flat plate portions 22, 32.

[0025] Alternatively, the fastener 2 may be a rivet used for crimping. In this case, the head of the rivet corresponds to the head 2a of the fastener 2, and the shank of the rivet corresponds to the shank 2b of the fastener 2. The fastener 2c of the fastener 2 corresponds to a flange formed when the tip of the shank 2b of the rivet is crushed and deformed after passing through the holes 5, 6 of the overlapping flat plate portions 22, 32. When a rivet is used as the fastener 2, the two flat plate portions 22, 32 are sandwiched and connected between the flange and the rivet head 2a. In the following description, a case where a bolt and a nut are mainly used as the fastener 2 is exemplified, but the following description is also the same when the fastener 2 is a rivet.

[0026] The pipe H is fixed with its side h placed on the upper surface 21a of the top plate portion 21 of the support material 20. The pipe H to be installed on the roof is, for example, a water supply pipe, a chimney pipe, or a connecting water supply pipe, and is assumed to have an outer diameter of 26 mm to 150 mm. The equipment foundations P are arranged at intervals of approximately 6 m, and the pipe support bases 10 are installed on the upper surfaces P1 of the equipment foundations P. Therefore, each pipe support base 10 supports a pipe H of approximately 6 m. In Figure 3, the pipe H fixed horizontally is shown by a solid line, and the pipe H fixed at an incline is shown by a two-dot chain line. As shown in this figure, whether the pipe H is horizontal or at any incline, the horizontal radial direction T of the pipe H is always a single horizontal direction.

[0027] When in use, the pipe support 10 is fixed to the equipment foundation P so that the receiving-side flat plate portion 22 of the receiving material 20 and the base-side flat plate portion 32 of the base material 30 extend vertically. The pipe support 10 is also fixed so that its front faces one direction in the axial direction of the pipe H. The pipe support 10 in this figure is fixed so that its front faces the right side of the figure and its side direction X faces the horizontal radial direction T of the pipe H.

[0028] FIG. 4 is a perspective view of the pipe support base 10 of the first embodiment shown in a separated state for the purpose of explanation. The pipe support 10 includes the above-mentioned receiving material 20, base material 30, and fastener 2, as well as a slippage prevention piece 1. This figure illustrates the pipe support 10 of the first embodiment having a continuous hole 5 and a through hole 6.

[0029] The pipe support 10 has two fasteners 2. The diameter of the shank 2b may be, for example, approximately 9.6 mm. Furthermore, when inserting the shank 2b into the holes 5, 6 in the receiving-side flat plate portion 22 and the base-side flat plate portion 32, the head 2a may be on the front side or the back side. The effect obtained by the fastener 2 is the same whether the shank 2b is inserted from the front side or the back side.

[0030] The slippage prevention piece 1 is a flat metal fitting having an axial hole 1a through which the shank 2b of the fastener 2 passes in the plate thickness direction Y. The axial hole 1a is sized to have a slight margin relative to the diameter of the head 2a of the fastener 2. In the following description, the outer shape of the slippage prevention piece 1 when viewed from the front is referred to as the "peripheral shape 1b." It is most preferable that the slippage prevention piece 1 has a ring shape with the peripheral shape 1b being a perfect circle and the shaft hole 1a at its center. This is because if the peripheral shape 1b of the slippage prevention piece 1 has this shape, there is no need to worry about the orientation due to rotation when installing, and workability is the best. However, the slippage prevention piece 1 is not limited to this, and may have a polygonal or elliptical shape when viewed from the front, or any other shape.

[0031] The receiving member 20 shown in FIG. 4 is an L-shaped steel having a top plate portion 21 and a receiving-side flat plate portion 22. A pair of U-bolt fixing holes 23 are provided in the top plate portion 21 of the receiving material 20, into which both ends of the U-bolt 7 for fixing the pipe H can be inserted from above. The U-bolt fixing holes 23 are oblong through-holes extending in the lateral direction X, or multiple through-holes arranged at intervals in the lateral direction X. Due to this shape of the U-bolt fixing holes 23, the pipe support base 10 can fix pipes H of various diameters to the receiving material 20. When fixing the pipe H to the receiving material 20, a U-band may be used instead of the U-bolt 7.

[0032] The receiving plate portion 22 extends downward from the front end of the top plate portion 21 during use. The receiving flat plate portion 22 is provided with a pair of through holes 6 through which the shank portion 2b of the fastener 2 passes.

[0033] The through holes 6 are through holes provided at positions corresponding to the continuous holes 5 described later. The through holes 6 illustrated in FIG. 4 are provided as a pair at the same height. The through holes 6 of this embodiment are horizontally elongated holes extending laterally in the in-plane direction of the receiving flat plate portion 22, and are provided at the lower end portion 22a of the receiving flat plate portion 22. Note that the "horizontal" direction in which the through holes 6 extend is not limited to the horizontal direction in the side direction X, but also includes a lateral component in the side direction X and an oblique lateral direction in the side direction X.

[0034] The base material 30 shown in FIG. 4 is an L-shaped steel having a bottom plate portion 31 and a base-side flat plate portion 32. The bottom plate portion 31 has anchor fixing holes 31a through which post-installed anchors 62 are passed, and is provided so that the post-installed anchors 62 can be directly hammered into the upper surface P1 of the equipment foundation P. When fixing the base material 30 to the upper surface P1 of the equipment foundation P, the bottom plate portion 31 is fixed so that it extends horizontally and the base-side flat plate portion 32 extends vertically. By directly hammering the bottom plate portion 31 into the upper surface of the equipment foundation P with the post-installed anchors 62, the position of the base material 30 can be firmly fixed to the installation position P.

[0035] The base-side flat plate portion 32 has a flat plate shape extending in the lateral direction X and the up-down direction Z. In use, the base-side flat plate portion 32 extends parallel to the receiving-side flat plate portion 22. The base-side flat plate portion 32 has at least one pair of continuous holes 5 at the same height. The continuous hole 5 is a hole formed by connecting a plurality of positioning holes 5a. The plurality of positioning holes 5a are formed at different positions in the vertical direction Z.

[0036] The positioning hole 5a is a hole formed so that at least a part of the outer periphery of the slippage prevention piece 1 can fit therein. The positioning hole 5a may be formed, for example, by being bored into the outer periphery shape 1b of the slippage prevention piece 1 so that at least a part of the outer periphery of the slippage prevention piece 1 can fit therein. There are multiple continuous holes 5, with at least one on each side of the center of the piping support 10 in the lateral direction X. The continuous holes 5 are preferably provided in pairs on the left and right sides of the center of the piping support 10 in the lateral direction X. For example, the continuous holes 5 illustrated in FIG. 4 are provided in three pairs spaced apart in the vertical direction Z. However, the present invention is not limited to this, and the shape, size, number, or orientation of the left and right continuous holes 5 in this embodiment are arbitrary, and for example, the left and right continuous holes 5 do not have to form pairs.

[0037] In the embodiment illustrated in Fig. 4, it is preferable that the pair of continuous holes 5 have the positioning holes 5a at the same height. The pair of continuous holes 5 are preferably provided symmetrically with respect to the center of the pipe support 10 in the lateral direction X, but they do not have to be symmetrical. For example, the pair of continuous holes 5 may be inclined in the same direction, such as when both the left and right sides of the pair of continuous holes 5 are inclined upward to the right. With this configuration, when the fastener 2 connects the receiving-side flat plate portion 22 and the base-side flat plate portion 32, the pipe support 10 of this embodiment can fit the slippage prevention piece 1 into one of the positioning holes 5a with the shank 2b passing through the shank hole 1a. At this time, the pair of slippage prevention pieces 1 fit into the positioning holes 5a located at the same height. As a result, the receiving-side flat plate portion 22 and the base-side flat plate portion 32 of the pipe support 10 are fastened together by the fastener 2 with the shank 2b passing through the continuous hole 5 and the through hole 6, as shown by the dashed dotted line. In the pipe support base 10, the height of the through-hole 6 can be changed by changing the positioning hole 5a into which the shaft portion 2b is inserted to another positioning hole 5a, and the height of the top plate portion 21 can be changed.

[0038] Next, the shape of the continuous hole 5 or the through hole 6 will be described. 5A and 5B are explanatory diagrams illustrating the effect that the displacement of the shaft portion 202b has on the position of the pipe H when a pipe support 200 other than the present invention is used. Fig. 5A is a rear view of the pipe H in its normal position, and Fig. 5B is a rear view of the pipe H when the shaft portion 202b on the right side of the figure has been displaced upward. The obliquely provided hole 205 in the base-side flat plate portion 232 of the pipe support 200 other than the present invention shown in this figure is wider than the continuous hole 5 of the first embodiment.

[0039] If the gap between the shaft portion 202b and the hole 205 provided in the base-side flat plate portion 232 is large, it is expected that the receiving material 220 will shift when wind pressure W or earthquake force is applied to the pipe H, even if the nut 202c is tightly fastened. For example, when wind pressure W is applied to the pipe H, the receiving material 220 will rotate around one of the shaft portions 202b as the axis of rotation, and the other shaft portion 202b will shift upward. For example, in the example of FIG. 5(A), when wind pressure W is applied to the pipe H from the right side of FIG. 5(A), the receiving material 220 will rotate around the left shaft portion 202b as the axis of rotation, and the right shaft portion 202b will shift upward, as shown in FIG. 5(B).

[0040] At this time, the range within which the receiving member 220 can rotate is limited to the angle at which the shaft 202b can move within the diagonally provided hole 205. The pipe H moves around the left shaft 202b by the same angle as the angle at which the right shaft 202b moves around the left shaft 202b. Because the distance from the left shaft 202b to the pipe H in FIG. 5 is greater than the distance between the pair of shafts, the movement distance of the pipe H is greater than the movement distance of the right shaft 202b even when rotated by the same angle. For example, in this figure, the position of the pipe H is shifted by more than twice the movement distance of the right shaft 202b. As described above, in a pipe support 10 of the type in which the receiving-side flat plate portion 22 of the receiving material 20 and the base-side flat plate portion 32 of the base material 30 are connected by a pair of fasteners 2, misalignment of the shank 2b significantly affects the position of the pipe H. If the position of the shank 2b is misaligned, the deformation of the pipe H will be greater than the deformation of the receiving material 220. Such large misalignment of the pipe H must be avoided. Therefore, a pipe support 10 of the type in which the receiving-side flat plate portion 22 of the receiving material 20 and the base-side flat plate portion 32 of the base material 30 are connected by a pair of fasteners 2 must be configured so that the shank 2b is less likely to misalign, even if the pipe H is subjected to a large wind pressure W.

[0041] FIG. 6 is an explanatory diagram of the relationship between the shape of the continuous hole 5 and the shaft portion 2b or the displacement prevention piece 1. As shown in FIG. FIG. 6(A) is a front view of the continuous hole 5 and the misalignment prevention piece 1, showing the relationship between the continuous hole 5 and the misalignment prevention piece 1. FIG.

[0042] The continuous hole 5 has a shape in which multiple positioning holes 5a are bored into the outer peripheral shape 1b of the slippage prevention piece 1 at different positions in the up-down direction during use, and are connected diagonally in the in-plane direction of the base-side flat plate portion 32. The positioning holes 5a are formed slightly larger than the outer diameter of the outer peripheral shape 1b of the slippage prevention piece 1. The sizes of the positioning holes 5a and the slippage prevention piece 1 are preferably such that the slippage prevention piece 1 can be smoothly fitted into the positioning holes 5a with one hand and the slippage prevention piece 1 fits snugly into the positioning holes 5a without rattle inside the positioning holes 5a. For example, when the slippage prevention piece 1 is fitted into the positioning holes 5a, the distance from the outer peripheral surface of the slippage prevention piece 1 to the inner wall surface 5d of the nearest positioning hole 5a is preferably 0.1 to 0.2 mm.

[0043] The continuous hole 5 shown in Fig. 6(A) has a shape in which five positioning holes 5a are connected so that the continuous hole 5 extends diagonally. The positioning holes 5a are formed so that at least a portion of the outer periphery of the slippage prevention piece 1 can fit into them. For example, in the example of Fig. 6(A), the positioning holes 5a have an inner wall surface 5d that forms an arc along a portion of the circumference of the slippage prevention piece 1. With this configuration, the continuous hole 5 has a protrusion 5b between adjacent and connected positioning holes 5a that prevents the displacement prevention piece 1 fitted in the positioning hole 5a from moving to the adjacent positioning hole 5a.

[0044] The protrusions 5b are portions that protrude inward in the width direction of the continuous hole 5. The distance between opposing protrusions 5b is preferably set smaller than the minimum diameter of the outer circumferential shape 1b of the slippage prevention piece 1. In the case of this figure, the outer circumferential shape 1b of the slippage prevention piece 1 is a perfect circle, so the diameter of the outer circumferential shape 1b itself is the minimum diameter. With this configuration, even if the maximum width of the continuous hole 5 is larger than the maximum diameter of the outer peripheral shape 1b of the slippage prevention piece 1, the presence of the convex portion 5b can prevent the slippage prevention piece 1 from moving to the adjacent positioning hole 5a.

[0045] Furthermore, the continuous hole 5 is shaped so that when the fastener 2 connects the receiving-side flat plate portion 22 and the base-side flat plate portion 32, the head 2a or fastener 2c of the fastener 2 hangs over the edge of the continuous hole 5 as shown in the checkered pattern in Fig. 6(A). As a result, the piping support 10 of this embodiment can firmly clamp the receiving-side flat plate portion 22 of the receiving material 20 and the base-side flat plate portion 32 of the base material 30 with the head 2a and fastener 2c.

[0046] FIG. 6(B) is a front view of the continuous hole 5 showing the relationship between the continuous hole 5 and the shaft portion 2b. In the construction work of laying the pipe H, the height of the pipe H may be adjusted after the pipe H has been fixed to the pipe support 10. In such cases, bolts and nuts are used as the fasteners 2, and a spirit level is placed on the pipe H that has been fixed to the pipe support 10 to check the level and the degree of slope of the pipe H. When changing the height of the support material 20, the support material 20 is supported with one hand to maintain the height of the support material 20, while the nut 2c is temporarily tightened with the other hand.

[0047] At this time, temporary tightening of nut 2c by hand may not be sufficient, and the height of pipe H may drop immediately if the hand supporting support material 20 is released. In such a case, while supporting support material 20 with pipe H on it with one hand, the worker must operate a wrench or the like with the other hand to temporarily tighten nut 2c, which is inefficient to work with.

[0048] In the continuous hole 5 of this embodiment, it is preferable that each positioning hole 5a has a shaft rest portion 5c on which the shaft portion 2b passed through the continuous hole 5 can be placed. The shaft rest portion 5c of the first embodiment shown in Figure 6 is the lower inner wall surface 5d of the positioning hole 5a bored into the circular outer peripheral shape 1b, and is a portion that curves downward. In other words, the shaft rest portion 5c of the first embodiment is a portion that has a cylindrical surface that is formed with a diameter larger than the diameter of the shaft portion 2b and curves downward.

[0049] The pipe support 10 of this embodiment has a shaft rest 5c in each positioning hole 5a of the continuous hole 5, so even in situations where the nut 2c cannot be tightly tightened by hand or a wrench cannot be used, the shaft 2b can be temporarily placed on the shaft rest 5c to prevent the support material 20 from dropping. As a result, the pipe support 10 of this embodiment can further improve the work efficiency of the pipe H installation work. Furthermore, in the pipe support base 10 of this embodiment, the fastener 2 does not fall from the target positioning hole 5a to the lower positioning hole 5a, so that the safety of the pipe H installation work can be improved.

[0050] Furthermore, since the shank 2b of the fastener 2 can be temporarily placed on the shank rest 5c at a height close to the desired height, the shank 2b will not drop even if the nut 2c is not temporarily tightened. Therefore, a rivet whose fastening is irreversible can be used as the fastener 2. However, the shape of the shaft rest portion 5c is not limited to this. The shaft rest portion 5c may have a curved surface, a horizontal surface, or an inclined surface formed by the inner wall surface 5d on the lower side of each positioning hole 5a. Other examples of the shaft rest portion 5c will be described later with reference to FIG. 7.

[0051] The minimum width of the continuous hole 5 is set to be larger than the diameter of the shaft portion 2b. For example, as shown in Figure 6(B), it is preferable that the minimum width of the continuous hole 5 is set to be just wide enough for the shaft portion 2b to pass through. Furthermore, the minimum width of the continuous hole 5 is always set smaller than the maximum diameter of the outer peripheral shape 1b of the displacement prevention piece 1. And it is preferable that the minimum width of the continuous hole 5 is set smaller than the minimum diameter of the outer peripheral shape 1b of the displacement prevention piece 1.

[0052] FIG. 7 is a front view of the continuous hole 5 having the shaft rest portion 5c and the misalignment prevention piece 1 of the second to fifth examples of the first embodiment. The continuous hole 5 and the displacement prevention piece 1 of the first embodiment are not limited to the shapes described above.

[0053] The shaft rest portion 5c may be a curved surface, a horizontal surface, or an inclined surface formed by the inner wall surface 5d on the lower side of each positioning hole 5a. (Second Example of the Shaft Stand 5c of the First Embodiment) FIG. 7A shows a shaft rest portion 5c of a second embodiment. The shaft rest portion 5c of the second embodiment may have a curved surface that is recessed downward and supports the lower end of the outer peripheral surface of the shaft portion 2b from below. The lower side of the outer peripheral surface of the shaft portion 2b in FIG. 7A is supported at two points by the protrusions 5b of the continuous hole 5, and there is a gap between the lower end of the outer peripheral surface of the shaft portion 2b and the lower end of the inner wall surface 5d below the positioning hole 5a. However, the shaft rest portion 5c of the second embodiment is not limited to this. The shaft rest portion 5c of the second embodiment may have a shape such that the lower outer peripheral surface of the shaft portion 2b fits snugly into the curved surface of the shaft rest portion 5c when the lower end of the outer peripheral surface of the shaft portion 2b is in contact with the lower end of the inner wall surface 5d below the positioning hole 5a, and the curved surface completely encases the lower outer peripheral surface of the shaft portion 2b. This shape allows the shaft portion 2b to be placed on the shaft rest portion 5c of the second embodiment.

[0054] (Third Example of the Shaft Stand 5c of the First Embodiment) 7B shows a shaft rest portion 5c of the third embodiment. The shaft rest portion 5c of the third embodiment has a horizontal surface that extends horizontally in the in-plane direction of the flat plate portion 22, 32 that has the continuous hole 5 and is longer than the radius of the shaft portion 2b. The continuous hole 5 is formed by boring multiple positioning holes 5a at different positions in the vertical direction, and the lower inner wall surface 5d of each positioning hole 5a is a horizontal surface. Therefore, the continuous hole 5 has a stepped unevenness on the lower inner wall surface 5d. Since the horizontal surface is longer than the radius of the shaft portion 2b, when the shaft portion 2b is temporarily placed, the lower end of the outer circumferential surface of the shaft portion 2b rests on the horizontal surface. Therefore, due to this shape, the shaft rest portion 5c of the third embodiment can also rest the shaft portion 2b.

[0055] (Fourth and fifth examples of the shaft rest portion 5c of the first embodiment) FIG. 7(C) shows the shaft rest portion 5c of the fourth embodiment, and FIG. 7(D) shows the shaft rest portion 5c of the fifth embodiment. The shaft rest portion 5c of the fourth embodiment has a sloped surface with an inclined flat surface, while the shaft rest portion 5c of the fifth embodiment has a curved surface that is inclined and curved downward. In both the fourth and fifth embodiments, the slopes are inclined downward away from the adjacent positioning hole 5a below which the positioning hole 5a having the shaft rest portion 5c is located, and extend longer in the lateral direction X than the radius of the shaft portion 2b. Therefore, when the shaft portion 2b is temporarily placed, the shaft portion 2b rolls in the direction away from the adjacent positioning hole 5a below, preventing the shaft portion 2b from falling into the adjacent positioning hole 5a below.

[0056] The anti-slip pieces 1 of the second to fifth embodiments all have an outer peripheral shape 1b that matches the shape of the shaft support portion 5c of each embodiment. The continuous holes 5 of the second to fifth embodiments all have a convex portion 5b at the boundary between adjacent positioning holes 5a. The shortest distance from the upper inner wall surface 5d to the convex portion 5b of each continuous hole 5 is the minimum width of the continuous hole 5, and this minimum width is the length that the shank 2b can just fit through. Regardless of the shape of the anti-slip piece 1 in a front view, it always has a shaft hole through which the shank 2b passes in the thickness direction. In other words, regardless of the shape of the anti-slip piece 1 in a front view, the minimum diameter of the anti-slip piece 1 is always larger than the diameter of the shank 2b. Therefore, if the minimum width of the continuous hole 5 is set to a width that just fits the shank 2b, the convex portion 5b can prevent the anti-slip piece 1 from moving to the adjacent positioning hole 5a. In addition, when the minimum width of the continuous hole 5 is sufficiently larger than the diameter of the shaft portion 2b, it is preferable that the shape of the anti-slip piece 1 is determined so that the minimum diameter of the anti-slip piece 1 is larger than the minimum width of the continuous hole 5. The shape of the shaft rest portion 5c is not limited to the above-mentioned shape, and may be any other shape as long as the shaft portion 2b can be placed thereon.

[0057] FIG. 8A is a front view of the through-hole 6 of the first embodiment, and FIG. 8B is a partially enlarged view thereof. As shown in Fig. 8(A), the through hole 6 in this embodiment is a horizontally elongated through hole. The width of the through hole 6 is large enough to allow the shank 2b of the fastener 2 to move laterally. More preferably, the width of the through hole 6 is large enough to allow the shank 2b to move in the lateral direction X as far as possible. In the through hole 6 illustrated in FIG. 8, the shaft portion 2b can be moved in the lateral direction X through the through hole 6 by passing it through the narrow part of the through hole 6 while swinging it up and down as shown by the two-dot chain line in this figure.

[0058] In addition, the width of the through hole 6 is set to a size such that when the fastener 2 connects the receiving side flat plate portion 22 and the base side flat plate portion 32, the edge of the head 2a or fastener 2c overlaps the edge (periphery) of the through hole 6. The through-hole 6 of the first embodiment has a plurality of shaft-shaped recesses 6b recessed upward on its upper inner wall surface 6a. The shaft-shaped recesses 6b have a shape that matches the shape of the outer peripheral surface of the shaft portion 2b.

[0059] Furthermore, it is preferable that the lower inner wall surface 6a of the through hole 6 protrudes upward at a position directly below the shaft-shaped recess 6b, and the remaining portion curves downward. The portion of the lower inner wall surface 6a of the through hole 6 that protrudes upward at a position directly below the shaft-shaped recess 6b is called a raised portion 6c. As shown in Figure 5, when wind pressure W or seismic force is applied to the pipe H, the receiving material 20 may rotate around one of the shanks 2b as the axis of rotation within the range inside the opening in the receiving-side flat plate 22 and the base-side flat plate 32, causing it to shift. In the case of the pipe support base 10 of this embodiment, the position of the shank 2b relative to the installation position P is not changed by the anti-slip piece 1, so when wind pressure W or seismic force is applied to the pipe H, the receiving-side flat plate 22 moves relative to the shank 2b as shown in Figure 8(B). In this case, the presence of the raised portion 6c narrows the range in which the through-hole 6 can move in the vertical direction Z relative to the shank 2b, so that shifting of the receiving material 20 can be suppressed to a range in which deformation of the pipe H does not cause practical problems.

[0060] 9A and 9B show a rear view (FIGS. 9A and 9B), a plan view (FIG. 9C), and a bottom view (FIG. 9D) of the pipe support stand 10 of the first embodiment having the continuous hole 5 and through hole 6 of the first example. The pipe support stand 10 shown in these figures is an example of a pipe support stand 10 that supports a pipe H with a maximum pipe diameter of approximately 100 mm. FIG. 9A shows the rear view when the distance between the top plate portion 21 of the receiving material 20 and the bottom surface portion 32 of the base material 30, which face each other vertically, is at its longest, and FIG. 9B shows the rear view when that distance is at its shortest. 10 is a diagram showing the positional relationship in the side direction X of the continuous holes 5 and through holes 6 of the first example of the pipe support base 10 of the first embodiment. In this figure, the broken lines indicate the positions of the shanks 2b (hereinafter referred to as fixing positions 9) that pass through the positioning holes 5a and the shank-shaped recesses 6b when the receiving material 20 is fixed.

[0061] As shown in Fig. 9, the base-side flat plate portion 32 of the first embodiment has multiple pairs of continuous holes 5 arranged at the same height and spaced apart in the vertical direction. For example, in the example of Fig. 9, three pairs of left and right pairs of continuous holes 5 are provided: an upper row, a middle row, and a lower row. Fig. 10 shows the positional relationship in the lateral direction X between one of the left and right pairs of continuous holes 5 at the same height and a through hole 6. With this configuration, the height of the top plate portion 21 of the receiving member 20 relative to the bottom plate portion 31 of the base member 30 is determined by passing the shaft portions 2b of the fasteners 2 through the positioning holes 5a at the same height on the left and right.

[0062] As shown in Figure 9, the receiving material 20 of the first embodiment changes the height of the top plate portion 21 by moving in the vertical direction relative to the base material 30. Therefore, the multiple continuous holes 5 lined up vertically have multiple positioning holes 5a at the same position in the lateral direction X. In the following description, the position in the lateral direction X where the positioning holes 5a or the shaft-shaped recesses 6b are arranged is referred to as a lane 8. For example, the piping support 10 shown in Figure 9 has five lanes 8 on each side of the receiving-side flat plate portion 22 and the base-side flat plate portion 32.

[0063] In the example shown in Figure 10, there are five lanes 8A to 8E. In this figure, lanes 8A to 8E are indicated by dashed lines. The lanes 8A to 8E are arranged at equal intervals in the lateral direction X. Each positioning hole 5a of the continuous hole 5 and each shaft-shaped recess 6b of the through hole 6 are arranged on this lane. The through hole 6 is provided at a position and length that matches the overall width of the continuous hole 5 so that the heads 2a that fasten to the fixing positions 9 of all the continuous holes 5 that can be connected to it can pass through. In other words, each shaft-shaped recess 6b is provided at a position that corresponds to the positioning hole 5a of the continuous hole 5 (the same position in the lateral direction X as those positioning holes 5a).

[0064] 10 shows multiple rows of continuous holes 5 separated into upper and lower rows, each with a positioning hole 5a in the same lane 8. For example, the leftmost positioning holes 5a of the middle and lower rows of continuous holes 5 are located on the same lane 8A. Also, on the central lane 8C, the left positioning hole 5a of the upper row of continuous holes 5, the central positioning hole 5a of the middle row of continuous holes 5, and the second positioning hole 5a from the right of the lower row of continuous holes 5 are located. In this way, in the pipe support 10 of the first embodiment, the multiple positioning holes 5a provided at different heights are arranged at the same position in the lateral direction X and share the same axial recess 6b. Therefore, the effort required to provide the axial recess 6b and the space occupied by the axial recess 6b in the receiving-side flat plate portion 22 can be reduced.

[0065] Furthermore, since the positioning holes 5a and the corresponding axial recesses 6b are provided at the same position in the lateral direction X, the end faces of the receiving material 20 and the base material 30 in the lateral direction X can be aligned simply by attaching the fastener 2 to the positioning holes 5a and axial recesses 6b on the same lane. The axial recesses 6b of the through holes 6 also function to position the receiving material 20. Due to the positioning function of the axial recesses 6b, the piping H can be passed straight through even if there is no play (room) in the size of the U-bolt fixing holes 23 provided in the top plate portion 21. Furthermore, when the receiving material 20 is connected to the base material 30, the axis portion 2b fits into the axis-shaped recess 6b, thereby preventing the receiving material 20 from shifting in the lateral direction X when wind pressure W or seismic force is applied to the piping H.

[0066] As shown by the two-dot chain lines, the positioning holes 5a, which are divided into upper, middle, and lower continuous holes 5, are also arranged at equal intervals in the vertical direction Z. In the pipe support base 10 of the first embodiment, the continuous hole 5 is divided into multiple holes in the vertical direction Z, so that multiple positioning holes 5a can be arranged in the same lane 8, thereby making it possible to make the slope of the continuous holes 5, which extend obliquely in the in-plane direction of the receiving-side flat plate portion 22 or the base-side flat plate portion 32, gentler. As a result, the distance in the side direction X between adjacent protrusions 5b in the continuous hole 5 can be made longer than the radius of the shaft portion 2b, so that a shaft rest portion 5c can be provided in each positioning hole 5a, further improving the work efficiency of laying the pipe H.

[0067] Furthermore, since the shank 2b can move in the lateral direction X both in the continuous hole 5 and in the through hole 6, it is not necessary to insert or remove the shank 2b of the fastener 2 when changing the position of the shank 2b.

[0068] 11 is a rear view of another pipe support 300 not according to the present invention, for explaining the effect of the continuous hole 5. This pipe support 300 has single round holes 305 of the same size as the diameter of the shaft portion 2b in the receiving-side flat plate portion 322 of the receiving member 320 and in the base-side flat plate portion 332 of the base member 330. Each round hole 305 in this figure is provided at the same position as the fixing position 9 of the pipe support 10 in FIG. 9(A). In the construction of laying the pipe H, the operation of changing the holes into which the fasteners 2 are inserted for one pipe support base 10 may be performed multiple times.

[0069] When this type of work is performed on a pipe support 300 that has many unconnected single round holes 305, the above-mentioned temporary tightening is performed after the insertion / removal process. For example, in the case where the fastener 2 is a bolt and nut, the insertion / removal process is a process of "turning the nut 2c to remove it from the shank 2b of the bolt, removing the shank 2b from the receiving-side flat plate portion 322 and the base-side flat plate portion 332, shifting the receiving material 320 in the vertical direction Z, inserting the shank 2b into another round hole 305, and turning the nut 2c onto the shank 2b."

[0070] In contrast, the continuous hole 5 and the through hole 6 of the piping support base 10 of the first embodiment are connected, and the shaft portion 2b can be moved from one end to the other in the lateral direction X. Therefore, by simply loosening the fastener 2c (e.g., a nut) and removing the anti-slip piece 1 from the positioning hole 5a while the shaft portion 2b remains inserted through the shaft hole 1a, the shaft portion 2b can be slid to another fixed position 9 while remaining inserted through the continuous hole 5 and the through hole 6. Therefore, the pipe support 10 of the first embodiment can omit the insertion and removal process from the height adjustment work of the pipe H, thereby reducing the labor required for the work.

[0071] As shown in Figure 9, it is preferable that the continuous holes 5 and the through holes 6 are provided in two locations each, symmetrically (i.e., bilaterally symmetrically) with respect to a vertical line extending in the up-down direction Z at the center of the lateral direction X of the piping support base 10. The arrangement of the positioning holes 5a may be set according to the determined pitch in the vertical direction Z of the fixing positions 9, the positions where the post-installed anchors 62 are fastened, and the length in the lateral direction X or vertical direction Z of the receiving-side flat plate portion 22 or the base-side flat plate portion 32. The "pitch in the vertical direction Z of the fixing positions 9" refers to the spacing J in the vertical direction Z of the fixing positions 9, which determines whether the height of the top plate portion 21 can change significantly each time the fixing positions 9 are shifted, or whether it must be possible to make fine adjustments every few millimeters.

[0072] For example, in the pipe support 10 of this embodiment illustrated in Fig. 9, the receiving material 20 and the base material 30 are short in the lateral direction X, so that the bottom plate portion 31 of the base material 30 can be fastened at the installation position P with only one post-installed anchor 62 at the center in the lateral direction X. The pipe support 10 illustrated in Fig. 9 has only one anchor fixing hole 31a at the center in the lateral direction X of the bottom plate portion 31. A cap 62a is placed on top of the post-installed anchor 62. Therefore, to prevent interference between the cap 62a of the post-installed anchor 62 and the fastener 2, the pipe support base 10 shown in Fig. 9 does not have a positioning hole 5a in the center of the bottom end, and instead has continuous holes 5 formed diagonally in the shape of the Chinese character for eight.

[0073] 12A and 12B are a rear view and a front view, respectively, of the pipe support 10 of the first embodiment having the continuous hole 5 and the through hole 6 of the second embodiment. The pipe support 10 shown in this figure is an example of a pipe support 10 that supports a pipe H having a maximum pipe diameter of approximately 150 mm. If the receiving material 20 and the base material 30 are long in the lateral direction X, as shown in Figure 12(A), two post-installed anchors 62 are required to fix the base material 30 to the installation position P. When fixing with two post-installed anchors 62, it is better to leave a larger gap between them to prevent the base material 30 from rattling.

[0074] Therefore, the piping support base 10 illustrated in Figure 12 (A) avoids providing positioning holes 5a at both ends of the lower end of the piping support base 10 in the side direction X by providing continuous holes 5 at an angle in a V shape so that the fastener 2 does not interfere with the caps 62a arranged at both ends in the side direction X. In this way, the pair of continuous holes 5 on the left and right sides of the pipe support 10 of the first embodiment may be provided in an eight-shape or a V-shape.

[0075] FIG. 12(B) is a front view of the pipe support base 10 of the first embodiment having the continuous hole 5 and the through hole 6 of the second embodiment. In the pipe support base 10 of the first embodiment, either the continuous hole 5 or the through hole 6 may be arranged on the front side. This is the same whether the continuous hole 5 or the through hole 6 is in the first example or the second example.

[0076] For example, Figure 12(B) shows a pipe support base 10 in which the through-holes 6 are arranged on the front side. As shown in this figure, when the receiving-side flat plate portion 22 and the base-side flat plate portion 32 are overlapped, if the flat plate portions 22, 32 in which the through-holes 6 are provided are arranged on the front side, a neat and excellent appearance with few openings can be obtained. On the other hand, when adjusting the height of the pipe H, with the pipe H attached to the support member 20, the shaft 2b must be moved while determining the direction in which the continuous hole 5 and the through hole 6 extend. During the height adjustment work, the worker views the pipe support stand 10 from diagonally above. Because the top plate 21 blocks the view from the back side of the flat plate portions 22, 32 of the pipe support stand 10, if the continuous hole 5 is on the back side, it is difficult for the worker to see the positions of the fasteners 2 and the continuous hole 5. Therefore, if the flat plate portions 22, 32 with the through hole 6 are positioned on the front side, the continuous hole 5 on the back side is difficult for the worker to see, making it difficult to adjust the height of the pipe H.

[0077] On the other hand, when the receiving side flat plate portion 22 and the base side flat plate portion 32 are overlapped so that the continuous hole 5 is positioned on the front side, the position of the continuous hole 5 and the fastener 2 can be clearly seen, which has the advantage of making it easier to adjust the height of the piping H. On the other hand, if the continuous hole 5 is located on the front side, it is expected that dust accumulated on the periphery (inner wall surface 5d) of the continuous hole 5 will be easily seen and become a nuisance.

[0078] Therefore, in the first embodiment of the piping support base 10, either the continuous hole 5 or the through hole 6 can be placed on the front side, so the worker can decide whether the continuous hole 5 or the through hole 6 should be placed on the front side depending on the situation. For example, when installing the pipe support 10 in a conspicuous location or when a large number of workers are required to install one pipe support 10, the through hole 6 may be located on the front side. Conversely, when installing the pipe support 10 in a location where few people will see it, such as a restricted rooftop, or when the height adjustment work of the pipe H must be performed by a single worker, the pipe support 10 may be installed with the continuous hole 5 on the front side.

[0079] In the pipe support 10 of the first embodiment, it is preferable that the continuous hole 5 is provided in the base-side flat plate portion 32 of the base material 30 and the through-hole 6 is provided in the lower end of the receiving-side flat plate portion 22 of the receiving material 20. Figure 13 is an explanatory diagram showing why it is preferable to provide the continuous hole 5 in the base material 30 and the through hole 6 in the receiving material 20. Figures 13(A) and 13(B) are rear views of the pipe support base 10 of the first embodiment in which the continuous hole 5 is provided in the base material 30 and the through hole 6 is provided in the receiving material 20. Figure 13(A) shows the case where the fastener 2 is attached to the lowest positioning hole 5a, and Figure 13(B) shows the case where the fastener 2 is attached to the highest positioning hole 5a. Figure 13(C) is a rear view of the pipe support base 10 of the first embodiment in which the continuous hole 5 is provided in the receiving material 20 and the through hole 6 is provided in the base material 30.

[0080] The pipe support 10 of this embodiment is configured so that the height of the receiving material 20 can be changed by increasing or decreasing the overlapping range of the receiving-side flat plate portion 22 and the base-side flat plate portion 32. Therefore, in order to provide a wide range of height adjustment, it is preferable that the through-hole 6 be located near the free end of the flat plate portions 22, 32 in the vertical direction Z. Since the receiving-side flat plate portion 22 of the receiving material 20 has a flat plate shape extending from top to bottom and its free end in the vertical direction Z is the lower end portion 22a of the receiving-side flat plate portion 22, the through-hole 6 of the pipe support base 10 having the through-hole 6 in the receiving material 20 is located near the lower end portion 22a of the receiving-side flat plate portion 22. Therefore, as shown in Figure 13(A), when the receiving material 20 is lowered to its lowest position, the fastener 2 is located near the lower end portion 22a of the receiving-side flat plate portion 22, so that the fastener 2 and the U-bolt 7 do not interfere with each other in the pipe support base 10 having the through-hole 6 in the receiving material 20.

[0081] 13(B), when fastener 2 is in the uppermost positioning hole 5a in pipe support 10 having through hole 6 in receiving material 20, top plate 21 is raised to an even higher position. Therefore, in pipe support 10 having through hole 6 in receiving material 20, fastener 2 and U-bolt 7 will not interfere with each other even when fastener 2 is in the uppermost positioning hole 5a.

[0082] In contrast, the base-side flat plate portion 32 of the base material 30 has a flat plate shape extending from bottom to top, so when a through hole 6 is provided in the base material 30, as shown in Figure 13(C), the through hole 6 is positioned near the upper end portion 32a, which is the free end portion of the base-side flat plate portion 32. Therefore, when the receiving material 20 is lowered to its lowest position, the fastener 2 is positioned just below the top plate portion 21 of the receiving material 20, and depending on the diameter of the piping H, the fastener 2 and the U-bolt 7 may interfere with each other.

[0083] Figure 13(D) shows a pipe support 10 that is an improvement over Figure 13(C). The pipe support 10 shown in Figure 13(D) has a continuous hole 5 formed in the receiving material 20. This pipe support 10 has the receiving side flat plate portion 22 of the receiving material 20 that is longer in the vertical direction Z than in Figure 13(C), and the distance from the top continuous hole 5 to the top plate portion 21 is longer than in Figure 13(C), thereby preventing interference between the fastener 2 and the U-bolt 7. Since the pipe support base 10 can be used even when the through hole 6 is provided in the base material 30 in this manner, the pipe support base 10 of the first embodiment is not limited to one in which the through hole 6 is provided in the receiving material 20.

[0084] However, as can be seen from a comparison between FIG. 13(A) and FIG. 13(D), the pipe support 10 of FIG. 13(D) becomes heavy due to the longer receiving-side flat plate portion 22. Therefore, in the pipe support 10 of this embodiment, it is most preferable that the continuous hole 5 is provided in the base material 30 and the through hole 6 is provided in the receiving material 20.

[0085] Furthermore, it is preferable that the shape of the through hole 6 extends laterally in the lateral direction X. As described above, the meaning of "laterally" as the direction in which the through hole 6 extends is not limited to the horizontal direction in the lateral direction X, but also includes a lateral component in the lateral direction X and an oblique lateral direction in the lateral direction X. Fig. 14 is an explanatory diagram comparing the through hole 6 extending horizontally in the side direction X with the through hole 406 extending diagonally in the side direction X. Fig. 14(A) is a rear view of the piping support base 10 of the first embodiment when the fastener 2 is fastened at the lowest fixing position 9. Fig. 14(B) is a rear view of the piping support base 10 in which the through hole 406 extends diagonally in the side direction X, in the opposite direction to the continuous hole 5 when the fastener 2 is fastened at the lowest fixing position 9.

[0086] As can be seen by comparing Figures 14(A) and 14(B), if the through hole 406 extends in a diagonal direction in the lateral direction X, opposite to the continuous hole 5, unnecessary space will be required below when inserting the fastener 2 into the lowest positioning hole 5a of the continuous hole 5. Therefore, in the pipe support 10 in which the through-hole 406 extends obliquely in the opposite direction to the continuous hole 5, both the receiving member 20 and the base member 30 are taller than the pipe support 10 of this embodiment, and the manufacturing cost increases because the steel plates are larger. Furthermore, if the heights of the receiving member 20 and the base member 30 are large, the amount of deformation increases when a vertical external force R acts on the side surface, which is not preferable.

[0087] 15A is a rear view of the piping support base 10 having a through hole 506 extending diagonally in the lateral direction X in the same direction as the continuous hole 5, and (B) is an enlarged view of the through hole 506 and the continuous hole 5. The dashed line in FIG. 15B indicates the position of the continuous hole 5. If the through hole 506 extends diagonally in the same direction as the continuous hole 5, even if the shaft portion 2b of the fastener 2 is inserted into the lowest positioning hole 5a of the continuous hole 5 as shown in Figure 15(A), no wasted space is created below.

[0088] However, if the through-hole 506 extends diagonally in the lateral direction X, in the same direction as the continuous hole 5, as shown in Figure 15(B), the distance that the flat plate portion 22, 32 (receiving flat plate portion 22 in this figure) having the through-hole 506 moves up and down becomes smaller than the distance that the fastener 2 moves in the vertical direction Z. For example, in the enlarged view shown in Figure 15(B), suppose that the fastener 2 moves from fixed position 9A to fixed position 9B, the distance equivalent to two positioning holes 5a. As a result, the fastener 2 moves upward by a distance C.

[0089] 15(B) represents the position of through hole 506 when fastener 2 is in fixed position 9A, and dashed line represents the position of through hole 506 when fastener 2 is in fixed position 9B. As shown in this figure, even when fastener 2 moves from fixed position 9A to fixed position 9B, the position of through hole 506, which extends diagonally in side direction X in the same direction as continuous hole 5, can only move a distance D in the vertical direction Z. It is desirable that the pipe support 10 have a larger range of movement of the receiving member 20 in the vertical direction Z relative to the base member 30. Therefore, as explained in Figures 14 and 15, it is most preferable that the through hole 6 of the piping support base 10 of this embodiment extend horizontally, among the lateral directions in the in-plane direction of the receiving side flat plate portion 22 or the base side flat plate portion 32.

[0090] Next, the slippage prevention piece 1 will be described. Fig. 16(A) is an enlarged rear view of the slippage prevention piece 1 and fastener 2 of the first embodiment, and Fig. 16(B) and Fig. 16(C) are views as viewed from the arrow BB in Fig. 16(A). Fig. 16 illustrates an example in which, of the two flat plate portions 22, 32, the base-side flat plate portion 32 has a continuous hole 5. The slippage prevention piece 1 is a flat metal fitting having an axial hole 1a through which the shank 2b of the fastener 2 passes in the plate thickness direction Y. The slippage prevention piece 1 shown in this figure has a circular outer peripheral shape 1b when viewed from behind, and is ring-shaped with a circular axial hole 1a in its center.

[0091] The size of the anti-slip piece 1 in this embodiment is such that the outer edge of the anti-slip piece 1 with the axial portion 2b passed through the axial hole 1a fits inside the outer edge of the head 2a or fastener 2c when viewed from the front or back. The axial hole 1a is sized to have a slight margin relative to the diameter of the head 2a. For example, when the shank 2b is passed through the shank hole 1a, the difference between the diameter of the shank hole 1a and the outer diameter of the male thread of the shank 2b is preferably 0.1 to 0.3 mm. As a result, the pipe support 10 of this embodiment has only a small gap around the shank 2b, which reduces the amount of misalignment between the receiving material 20 and the base material 30. In addition, because there is almost no gap around the shank 2b, the pipe support 10 of this embodiment can limit deformation of the pipe H to a range that does not cause practical problems, even if the receiving material 20 is misaligned relative to the base material 30.

[0092] 16(A) and 16(B) and 16(C), the anti-slip piece 1 fills the space (gap) between the inner wall surface 5d of the continuous hole 5 and the head 2a, which is sandwiched between the receiving flat plate portion 22 and the fastener 2c or head 2a of the fastener 2, in the in-plane direction of the base-side flat plate portion 32. This prevents the head 2a of the fastener 2 from moving in the in-plane direction of the base-side flat plate portion 32, and therefore prevents the receiving flat plate portion 22 and the base-side flat plate portion 32 from shifting in their in-plane directions. That is, for example, when a large wind pressure W or earthquake force acts on the pipe H, if there is no slippage prevention piece 1, as described above in Figure 5, the receiving material 20 may rotate around the shank 2b of one of the fasteners 2 as the axis of rotation, by the amount of the vertical gap between the shank 2b of the fastener 2 and the continuous hole 5, and may become misaligned. If this misalignment occurs, the misalignment will become even larger in positions where the radius of rotation of the top plate 21 of the receiving material 20 is large, and there is a possibility that adverse stress will be generated in the pipe H.

[0093] In contrast, the pipe support 10 of this embodiment is provided with the slippage prevention piece 1, so that the position of the head 2a in the in-plane direction of the base-side flat plate portion 32 is fixed by the inner wall surface 5d of the continuous hole 5 and the slippage prevention piece 1. The base material 30 is fixed at the installation position P and does not change its position. Therefore, even if a force is applied to the receiving material 20 to displace the receiving flat plate portion 22 in the in-plane direction, the position of the head 2a does not change, and therefore the range of displacement of the receiving flat plate portion 22 in the up-down direction Z is limited to the distance of the gap between the head 2a and the inner wall surface 6a of the through-hole 6. Therefore, the pipe support base 10 of this embodiment, by having the displacement prevention piece 1, can prevent the receiving material 20 from moving in the in-plane direction of the receiving flat plate portion 22.

[0094] Figure 16(B) shows a case where the thickness of the anti-slip piece 1 is the same as the thickness of the flat plate portions 22, 32 having the continuous hole 5, and Figure 16(C) shows a case where the thickness of the anti-slip piece 1 is thinner than the thickness of the flat plate portions 22, 32 having the continuous hole 5. As shown in these figures, the thickness of the anti-slip piece 1 may be the same as the thickness of the flat plate portion 22, 32 into which the anti-slip piece 1 fits (in this figure, the base side flat plate portion 32), or may be thinner than that thickness.

[0095] 16(A) shows with a checkerboard pattern the area where friction occurs between the receiving-side flat plate portion 22 and the base-side flat plate portion 32 when the fastener 2c is tightly fastened. Also, with a grid pattern, the area where friction occurs between the receiving-side flat plate portion 22 and the slippage prevention piece 1 when the thickness of the slippage prevention piece 1 is the same as the thickness of the base-side flat plate portion 32.

[0096] When the thickness of the slippage prevention piece 1 is the same as the plate thickness of the base-side flat plate portion 32 of the base material 30, frictional forces are generated in the base-side flat plate portion 32 of the base material 30, the receiving-side flat plate portion 22 of the receiving material 20, and the slippage prevention piece 1, respectively, to resist slippage. That is, in this case, frictional forces are generated in the range that combines the lattice pattern range and the checkerboard pattern range in Figure 16(A). On the other hand, if the slippage prevention piece 1 is thinner than the plate thickness of the base-side flat plate portion 32, frictional force occurs only in the area of ​​the checkered pattern in FIG. 16(A). In this case, if the force fastening fastener 2c is the same and therefore the normal force exerted by head 2a of fastener 2 and fastener 2c does not change, even if the thickness of slippage prevention piece 1 is thinner than the plate thickness of base-side flat plate portion 32, a frictional force of the same degree as when the thickness of slippage prevention piece 1 is the same as the plate thickness of base-side flat plate portion 32 will be generated. Note that "the force fastening fastener 2c is the same" means when the torque to tighten the nut is the same when fastener 2 is a bolt and nut, or when the pressure applied to the tip of shank 2b when creating a flange is the same when fastener 2 is a rivet.

[0097] In other words, for example, suppose we compare the ``area that combines both the grid pattern and the checkered pattern'' in Figure 16(A) where frictional force occurs when the anti-slip piece 1 is the same thickness as the base side flat plate portion 32, with the ``area with only the checkered pattern'' where frictional force occurs when the anti-slip piece 1 is thinner than the base side flat plate portion 32. In this embodiment, the materials of the receiving material 20, anti-slip piece 1, and base material 30 of the two compared items are the same, so the friction coefficient of the ``area with only the checkered pattern'' and the friction coefficient of the ``area with both the grid pattern and checkered pattern combined'' are the same.

[0098] Furthermore, if the force for fastening the fastener 2c is the same, the total normal force applied to the entire fixed position 9 by the head 2a and the fastener 2c will be the same. Frictional force is calculated by multiplying the normal force by the coefficient of friction.

[0099] Therefore, the friction force generated in the "area including both the grid pattern and the checkered pattern" in Figure 16(A) when the anti-slip piece 1 has the same plate thickness as the base side flat plate portion 32, and the friction force generated in the "area including only the checkered pattern" when the anti-slip piece 1 is thinner than the plate thickness of the base side flat plate portion 32, are calculated as the product of the same friction coefficient and the same normal force, and are therefore of the same order of magnitude. In other words, the magnitude of the normal force per unit area generated by head 2a and fastener 2c is inversely proportional to the area of ​​the range in which the friction force is generated. Because the "area with both the grid and checkered patterns" has a larger area than the "area with only the checkered pattern," the normal force per unit area when the force fastening fastener 2c is the same will be smaller than the "area with only the checkered pattern."

[0100] As a result, whether the thickness of the slippage prevention piece 1 is thinner than the plate thickness of the base-side flat plate portion 32 of the base material 30 or the same thickness, the resistance to slippage will be the same. Therefore, the same frictional force is obtained whether the thickness of the anti-slip piece 1 is the same as that of the base side flat plate portion 32 or thinner than that of the base side flat plate portion 32, so the thickness of the anti-slip piece 1 may be the same as that of the base side flat plate portion 32 or thinner than that of the base side flat plate portion 32.

[0101] In the first embodiment, the pipe support base 10 has the above-mentioned configuration, whereby the anti-slip piece 1 fills the gap in the vertical direction Z between the peripheral surface of the shaft portion 2b and the inner wall surface 5d of the continuous hole 5, thereby preventing the receiving material 20 and the base material 30 from shifting relative to each other with one shaft portion 2b as the rotation axis. Furthermore, in the pipe support 10 of this embodiment, the shaft portion 2b fits into the shaft-shaped recess 6b of the through-hole 6 of the receiving material 20, so that the receiving material 20 can be prevented from shifting in the lateral direction X.

[0102] Furthermore, in the pipe support 10 of this embodiment, multiple positioning holes 5a are connected with a width that allows the shank 2b to pass through, forming each continuous hole 5, so the number of times that the shank 2b of the fastener 2 needs to be inserted and removed can be reduced by the number of boundaries between the positioning holes 5a. For example, in the pipe support 10 of this embodiment shown in Figures 9 and 12, the continuous hole 5 is divided into multiple holes, each one corresponding to a plurality of positioning holes 5a, so the number of times that the shank 2b of the fastener 2 needs to be inserted and removed can be reduced to one or two times when adjusting the height of the receiving material 20. Furthermore, in this embodiment, the piping support base 10 has a through hole 6 that is a long horizontal opening, and the continuous hole 5 is divided into multiple holes, each with a plurality of positioning holes 5a, so that the slope of the continuous hole 5 can be made gentle, and therefore an axis support portion 5c can be provided in each positioning hole 5a.

[0103] In addition, in this embodiment, the piping support base 10 divides the continuous hole 5 into multiple parts, which allows the distance between the positioning holes 5a to be appropriately set, thereby ensuring a width and area of ​​engagement between the fastener 2c or head 2a and the base material 30 that satisfies the bending strength. Furthermore, in the pipe support 10 of the first embodiment, the lanes 8 where the fixing positions 9 are provided can be spaced widely apart, and therefore the axial recesses 6b can also be spaced widely apart. Therefore, each axial recess 6b can be made deep, which can prevent the receiving material 20 from shifting in the lateral direction X.

[0104] Furthermore, in this embodiment, the pipe support base 10 does not have any small areas at the contact area between the inner wall surface 5d of the continuous hole 5 and the outer peripheral surface of the anti-slip piece 1, so there is no need to worry about the edges of the continuous hole 5 being locally deformed. Therefore, the pipe support 10 of this embodiment can resist a large external force R because the shape of the continuous hole 5 does not have any portion with low bending strength.

[0105] Therefore, the pipe support stand 10 of this embodiment does not require spacers to adjust the height of the receiving material 20, and does not require multiple support stands of different heights, thereby reducing the construction effort. In addition, in the piping support base 10 of this embodiment, the continuous hole 5 has a shape in which multiple positioning holes 5a are connected with a width that allows the head 2a to pass through, so the height of the receiving material 20 can be adjusted by sliding the shank 2b of the fastener 2 to the adjacent positioning hole 5a, thereby reducing the effort required to insert and remove the shank 2b of the fastener 2.

[0106] In addition, the pipe support 10 of this embodiment has fewer components than a pipe support that adjusts the height of the support member 20 with fully threaded bolts. Since the length in the lateral direction X is shorter, the weight of the steel plate can be reduced, thereby reducing manufacturing costs. The rooftop where the pipe support 10 is used is located at the end of an inspection hatch in the ceiling of the top floor, accessed by climbing a ladder or ramp from the top floor of the building. Installation work requires workers to carry the pipe support 10 onto the rooftop. Furthermore, carrying many pipe support 10 onto the rooftop requires multiple trips up and down ladders or ramps, which is time-consuming. Therefore, from the standpoints of safety and workability, the pipe support 10 needs to be as lightweight as possible. Since the length in the lateral direction X is shorter, the pipe support 10 of this embodiment is lighter than a pipe support that adjusts the height of the support member 20 with fully threaded bolts, making it easier to transport and improving workability. Therefore, by using the pipe support base 10 of this embodiment, the time and effort required for adjusting the height of the receiving material 20 can be reduced, thereby saving labor and reducing facility construction costs.

[0107] (Second embodiment) Figure 17 is a rear view of the pipe support 10 of the second embodiment. The pipe support 10 of Figure 17(A) has an anchor fixing hole 31a at the center in the lateral direction X and is intended to support a pipe H with a maximum pipe diameter of approximately 100 mm. The pipe support 10 of Figure 17(B) has anchor fixing holes 31a at both ends in the lateral direction X and is intended to support a pipe H with a maximum pipe diameter of approximately 150 mm.

[0108] Each of the pair of continuous holes 5 in the second embodiment has a first inclined portion 5f, a second inclined portion 5g, and a bent portion 5e. The first inclined portion 5f is a portion of the continuous hole 5 where the positioning holes 5a become higher toward one side in the side direction X.

[0109] The second inclined portion 5g is a portion of the continuous hole 5 that is located above or below the first inclined portion 5f and in which the position of the positioning hole 5a becomes higher as it moves toward the other side in the lateral direction. The bent portion 5e is a portion of the continuous hole 5 where the first inclined portion 5f and the second inclined portion 5g are connected, and the series of positioning holes 5a appears to be bent. In Figure 17(A), the bent portion 5e is the portion surrounded by a three-dot chain line.

[0110] The pipe support 10 of FIGS. 17(A) and 17(B) has continuous holes 5 in which the positioning holes 5a are connected in the shape of the hiragana character "V". As shown in this figure, the continuous holes 5 of the second embodiment are connected in a "L" shape, and the positioning holes 5a of the bent portion 5e are connected in the vertical direction. For example, the positioning holes 5a of the fixing positions 9C and 9D in FIG. 17(A) are connected in the up-down direction Z without any diagonal misalignment. Therefore, the positioning hole 5a of the fixing position 9C, which is located on the upper side of the bent portion 5e, does not have a "lower inner wall surface 5d of the positioning hole 5a," and therefore does not have a shaft support portion 5c. For example, when fastening the fastener 2 at the fixing position 9C during use, the shaft support portion 5c of the positioning hole 5a of the fixing position 9D may be used. The same applies to the pipe support base 10 shown in FIG. 17(B).

[0111] The continuous hole 5 shown in FIG. 17(A) is illustrated so that the number of fixing positions 9, the height of the fixing positions 9, and the overall width of the continuous hole 5 in the lateral direction X are the same as those of the pipe support 10 of the first embodiment illustrated in FIG. 9(B). The continuous hole 5 shown in FIG. 17(A) has only one bent portion 5e, so the positioning holes 5a are arranged closer together than in the continuous hole 5 shown in FIG. 9(B). Therefore, the spacing between the positioning holes 5a is shorter than in the continuous hole 5 shown in FIG. 9(B), and the stability of the shaft support portion 5c is lower than in the continuous hole 5 shown in FIG. 9(B). However, the lower inner wall surface 5d of the positioning hole 5a still slopes downward away from the adjacent positioning hole 5a below and extends in the lateral direction X longer than the radius of the shaft portion 2b. Therefore, the lower inner wall surface 5d of the positioning hole 5a in FIG. 17(A) functions as the shaft support portion 5c. Therefore, the pipe support 10 shown in FIG. 17(A) can also have the shaft rest portion 5c.

[0112] The slope of the continuous hole 5 of the piping support stand 10 shown in Figure 17(B) is the same as the slope of the continuous hole 5 described in Figure 12(A), and therefore has a stable axis support portion 5c similar to the piping support stand 10 of the first embodiment described in Figure 12. In this way, the pipe support 10 of the second embodiment can have a stable shaft rest portion 5c similar to that of the first embodiment, depending on the lengths of the receiving member 20 and the base member 30 in the side direction X.

[0113] The pipe support 10 shown in FIG. 17(C) has continuous holes 5 in which the positioning holes 5a are connected in a Z-shape. For example, the pipe support 10 shown in FIG. 17(C) is drawn by flipping the middle continuous hole 5 of the pipe support 10 of the first embodiment shown in FIG. 9(B) from side to side and connecting the upper, middle, and lower continuous holes 5. As can be seen from this, the pipe support 10 shown in FIG. 17(C) is identical to the pipe support 10 of the first embodiment shown in FIG. 9(B) in the number of fixing positions 9, the height of the fixing positions 9, and the overall width of the continuous holes 5 in the lateral direction X. In addition, the number of lanes 8, the spacing between the lanes 8, and the gradient of the continuous holes 5 are also identical. Therefore, the pipe support 10 of FIG. 17(C) has a stable shaft rest portion 5c similar to the pipe support 10 of the first embodiment shown in FIG. 9(B).

[0114] In this way, by increasing the number of bent portions 5e, the pipe support 10 of the second embodiment can have a stable shaft rest portion 5c by making the slope of the continuous hole 5 gentler. The number of bent portions 5e included in the continuous hole 5 of the second embodiment is not limited to one or two, but may be three or more. In other words, the continuous hole 5 of the second embodiment may have positioning holes 5a connected in a zigzag pattern.

[0115] In this way, the continuous holes 5 of the piping support base 10 of the second embodiment are formed by connecting multiple continuous holes 5 with different slope directions to form a single unit, which has the advantage that the shank 2b of the fastener 2 does not need to be inserted or removed when sliding it from the top fixing position 9 to the bottom fixing position 9. Furthermore, by increasing the number of bending portions 5e or lengthening the length of the receiving material 20 and the base material 30 in the side direction X, the slope of the continuous hole 5 can be made gentler, thereby providing a stable shaft support portion 5c. Other configurations, usage methods, and effects of the pipe support 10 of the second embodiment are similar to those of the first embodiment.

[0116] (Third embodiment) FIG. 18 is a rear view of the pipe support 10 of the third embodiment. The pipe support 10 of the third embodiment has only one pair of continuous holes 5, which are connected to positioning holes 5a at an angle in the in-plane direction of the flat plate portion 22, 32 having the continuous holes 5. Note that the continuous hole 5 of the third embodiment does not have a bent portion 5e. The continuous holes 5 shown in this figure are drawn so that the number of fixing positions 9, the height of the fixing positions 9, and the overall width of the continuous holes 5 in the lateral direction X are the same as those of the pipe support base 10 of the first embodiment shown in Figure 9(B). Therefore, the continuous holes 5 shown in Figure 18 have shorter intervals between the positioning holes 5a than the continuous holes 5 shown in Figure 9(B), and the positioning holes 5a are arranged closer together.

[0117] Therefore, if the same number of fixing positions 9 as in the pipe support 10 of the first embodiment illustrated in Fig. 9(B) is provided, the pipe support 10 of the third embodiment does not have the shaft rest portion 5c. Note that, in the pipe support 10 of the third embodiment, the length of the receiving material 20 and the base material 30 in the side direction X can be made longer than in the pipe support 10 illustrated in Fig. 9(B), thereby making it possible to make the slope of the continuous hole 5 gentler and provide a stable shaft rest portion 5c. With this configuration, the pipe support base 10 of the third embodiment has positioning holes 5a connected from the top to the bottom to form one continuous hole 5, so that the shaft portion 2b of the fastener 2 does not need to be inserted or removed when sliding it from the top fixing position 9 to the bottom fixing position 9.

[0118] In addition, in this embodiment, the pipe support base 10 does not have any small areas at the contact area between the inner wall surface 5d of the continuous hole 5 and the outer surface of the anti-slip piece 1, so there is no need to worry about the edges of the continuous hole 5 being locally deformed. Therefore, the pipe support 10 of this embodiment can resist a large external force R because the shape of the continuous hole 5 does not have any portion with low bending strength. Other configurations, usage methods, and effects of the pipe support 10 of the third embodiment are similar to those of the first or second embodiment.

[0119] (Fourth embodiment) Figure 19 is an explanatory diagram of the pipe support 10 of the fourth embodiment. Figure 19(A) is a rear view, and Figure 19(B) is a front view. Note that Figure 19(B) omits the illustration of the fastener 2. 19(C) and 19(D) are front views of the continuous hole 5 (upper row) and the deviation prevention piece 1 (lower row) of the first to third examples of the pipe support base 10 of the fourth embodiment. Note that Fig. 19(A) and Fig. 19(B) show the pipe support base 10 having the continuous hole 5 and the deviation prevention piece 1 of the first example of the fourth embodiment.

[0120] As shown in Fig. 19(A), the pipe support 10 of the fourth embodiment is characterized in that each of a pair of continuous holes 5 has multiple positioning holes 5a at different positions in the vertical direction Z but at the same position in the lateral direction X. In other words, the pipe support 10 of the fourth embodiment has one continuous hole 5 on each side, with the positioning holes 5a connected in a vertical row. Furthermore, as shown in Fig. 19(B), the through holes 6 of the fourth embodiment are provided in pairs at the same height.

[0121] In this embodiment, the continuous holes 5 are arranged such that the positioning holes 5a from the top to the bottom are aligned vertically during use, ensuring a width sufficient for the shaft portions 2b to pass through. With this configuration, the pipe support base 10 of this embodiment has only one lane 8 on each side. Therefore, the through hole 6 of the pipe support base 10 of the fourth embodiment is not a horizontally long opening like those of the first to third embodiments. Since the pipe support base 10 of the fourth embodiment has only one lane 8 on each side, there is no need to slide the shaft portion 2b in the lateral direction X inside the through hole 6 when changing the positioning hole 5a into which the fastener 2 is inserted.

[0122] 19(B), the through hole 6 in the fourth embodiment is a through hole that is slightly larger than the diameter of the shank 2b and has a perfect circle shape in a front view. For example, when the shank 2b is passed through the through hole 6, the difference between the diameter of the through hole 6 and the outer diameter of the male thread of the shank 2b is preferably 0.1 to 0.3 mm. As a result, in the pipe support 10 of this embodiment, there is almost no gap between the inner wall surface 6a of the through hole 6 and the shank 2b, which prevents the receiving material 20 from shifting relative to the base material 30. In the example shown in Figure 19, the continuous hole 5 of the fourth embodiment is provided in the base material 30 and the through hole 6 is provided in the receiving material 20, but as in the first embodiment, the continuous hole 5 may be provided in the receiving material 20 and the through hole 6 may be provided in the base material 30.

[0123] In the continuous hole 5 of the fourth embodiment, similarly to the second and third embodiments, the positioning holes 5a from the top to the bottom are connected to form one continuous hole 5, so that it is not necessary to insert or remove the shank 2b when sliding the shank 2b of the fastener 2 from the top fixing position 9 to the bottom fixing position 9. Therefore, when adjusting the height of the receiving material 20, the effort of inserting or removing the shank 2b of the fastener 2 can be saved.

[0124] Furthermore, in the pipe support 10 of this embodiment, there is no small portion at the contact area between the inner wall surface 5d of the continuous hole 5 and the outer circumferential surface of the slippage prevention piece 1, so there is no need to worry about localized deformation of the edge of the continuous hole 5. Therefore, the pipe support 10 of this embodiment can withstand a large external force R because the shape of the continuous hole 5 does not have any portion with low bending strength. The pipe support 10 of this embodiment has no slope in the continuous holes 5 and does not have the shaft rest portion 5c. In this respect, the first and second embodiments, which can be provided with the shaft rest portion 5c, can improve the work efficiency of adjusting the height of the receiving material 20 compared to the pipe support 10 of the fourth embodiment.

[0125] (First Example of Continuous Hole 5 of Fourth Embodiment) 19(C) is a front view of the continuous hole 5 (upper row) and the misalignment prevention piece 1 (lower row) of the first example of the pipe support base 10 of the fourth embodiment. This figure illustrates the positioning hole 5a and the misalignment prevention piece 1, the size of which when viewed from the front is the same as that of the positioning hole 5a and the misalignment prevention piece 1 of the first embodiment shown in FIG. As shown in Figure 19(C), the continuous holes 5 of the fourth embodiment do not have a slope, and therefore the spacing between the positioning holes 5a is closer than in the continuous holes 5 that have a slope. Therefore, if the positioning holes 5a and the slippage prevention pieces 1 of the fourth embodiment are the same size as the pipe support 10 of the first embodiment shown in Figure 9, the width and area of ​​the engagement between the fastener 2c or head 2a of the fastener 2 and the base material 30 will be smaller than in the first to third embodiments, as shown by the checkered pattern. Note that even if the width and area of ​​the engagement between the fastener 2c or head 2a of the fastener 2 and the base material 30 are the sizes exemplified in Figure 19(C), there is almost no practical impact.

[0126] (Second Example of the Continuous Hole 5 of the Fourth Embodiment) 19(D) is a front view of the continuous hole 5 (upper row) and the misalignment prevention piece 1 (lower row) of the second example of the pipe support base 10 of the fourth embodiment. The positioning hole 5a and the misalignment prevention piece 1 of the second example are smaller in size in front view than those of the first example. As a result, as shown in the checkered pattern, by making the diameter of the positioning hole 5a and the anti-slip piece 1 small, even in the fourth embodiment, it is possible to ensure a large engagement width and area between the fastener 2c or head 2a of the fastener 2 and the base material 30.

[0127] Furthermore, the positioning hole 5a in the second example of the fourth embodiment has a smaller diameter, so that the inner wall surface 5d is recessed deeper than in the first example of the fourth embodiment. In other words, in the fourth embodiment, the difference between the maximum and minimum widths of the continuous hole 5 is larger in the second example than in the first example. Therefore, in this embodiment, the slippage prevention piece 1 of the second embodiment can more firmly hold the fastener 2 at the fixed position 9 where it is inserted than the first embodiment.

[0128] (Third Example of the Continuous Hole 5 of the Fourth Embodiment) 19(E) is a front view of the continuous hole 5 (upper row) and the slippage prevention piece 1 (lower row) of the third example of the pipe support base 10 of the fourth embodiment. The slippage prevention piece 1 of the third example of this embodiment has the same minimum radial thickness as the slippage prevention piece 1 of FIG. 19(D). The slippage prevention piece 1 has a protrusion 1c, part of which protrudes outward when viewed from the front. The slippage prevention piece 1 has the protrusion 1c extending to both sides in the lateral direction X when in use. With this configuration, the slippage prevention piece 1 of the third example of this embodiment can use the protrusion 1c to deeply engage with the recess of the positioning hole 5a without significantly reducing the engagement width and area between the fastener 2c or head 2a of the fastener 2 and the base material 30, compared to the second example of this embodiment. In other words, while ensuring a large maximum diameter of the slippage prevention piece 1, it is also possible to ensure a large engagement width and area between the fastener 2c or head 2a of the fastener 2 and the base material 30. Therefore, the slippage prevention piece 1 of the third example of this embodiment can also firmly remain in the fixed position 9 where the fastener 2 is inserted.

[0129] Furthermore, the slippage prevention piece 1 of the third example of this embodiment may have an operation protrusion 1d that extends in one direction in the vertical direction Z during use. During use, the operation protrusion 1d extends in the vertical direction Z to the outside of the outer periphery of the fastener 2c or head 2a of the fastener 2. With this configuration, by operating the operation protrusion 1d with a finger and rotating it around the shank 2b, it is possible to align the protrusion 1c with the recess of the positioning hole 5a by feel, even if the slippage prevention piece 1 is hidden by the fastener 2c or head 2a of the fastener 2 and cannot be seen. Furthermore, if the operating protrusion 1d is larger than the protrusion 1c, the displacement prevention piece 1 rotates due to gravity so that the operating protrusion 1d faces directly downward, making it easier to align the protrusion 1c.

[0130] As such, the fourth embodiment of the piping support stand 10 has lower work efficiency than the first and second embodiments in that it does not have the shaft support portion 5c, but it has better work efficiency than the first embodiment in that it does not require inserting or removing the shaft portion 2b of the fastener 2 when changing the height of the receiving material 20. Furthermore, in the fourth embodiment, the inner wall surface 6a of the through hole 6 can be positioned as close as possible to the circumferential surface of the shaft portion 2b, making it possible to configure the receiving material 20 so that it is less likely to shift in position relative to the base material 30 than in the first to third embodiments of the pipe support base 10. Other configurations, usage methods, and effects of the pipe support 10 of the fourth embodiment are similar to those of the first to third embodiments.

[0131] FIG. 20 is a rear view of the pipe support 10 of the fifth embodiment. As shown in FIG. 20, the pipe support 10 of the fifth embodiment is characterized in that either or both of the continuous hole 5 and the through hole 6 are not separated into left and right sides of the pipe support 10.

[0132] For example, the pipe support 10 of the fifth embodiment may have a continuous hole 5 in which the left and right continuous holes 5 of the pipe support 10 are connected to form one unit, such as the longest continuous hole 5 in Fig. 20. Furthermore, the pipe support 10 of this embodiment may have only one through hole 6 extending laterally in the side direction X, as shown in Fig. 20, and the shafts 2b of two fasteners 2 may be passed through the single through hole 6. Other configurations, usage methods, and effects of the pipe support 10 of the fifth embodiment are similar to those of the first to third embodiments.

[0133] FIG. 21 is a rear view of the pipe support 10 of the sixth embodiment. In the pipe support base 10 of the first to fourth embodiments, the positioning holes 5a and through holes 6 arranged on the left and right sides of the center in the side direction X of the pipe support base 10 are provided at the same height. In contrast, the pipe support base 10 of the sixth embodiment is characterized in that the positioning holes 5a or through holes 6 arranged on the left and right sides of the center in the side direction X of the pipe support base 10 are provided at different heights.

[0134] For example, in the pipe support base 10 of the sixth embodiment, when the shaft 2b is inserted into a certain right positioning hole 5a to connect the flat plate portions 22 and 32, the left positioning hole 5a that aligns with the left through-hole 6 may be positioned higher by a predetermined length (e.g., 3 mm) than the right positioning hole 5a into which the shaft 2b is inserted. In this case, the left through-hole 6 and the other left positioning hole 5a are also positioned higher by the same predetermined length (3 mm in this example). In other words, if the distance J between the fixing positions 9 in the vertical direction Z is the same on the left and right, even if the heights at which the positioning holes 5a and the through-holes 6 are arranged are different on the left and right, the receiving member 20 can be attached to the base member 30 at different positions in the vertical direction Z while keeping the upper surface 21a horizontal. Other configurations, usage methods, and effects of the pipe support 10 of the sixth embodiment are similar to those of the first to fourth embodiments.

[0135] According to the present invention described above, the base-side flat plate portion 32 of the base material 30 and the receiving-side flat plate portion 22 of the receiving material 20 are overlapped and connected by the fastener 2 through the shank 2b. The continuous hole 5 provided in one of the base-side flat plate portion 32 and the receiving-side flat plate portion 22 has a shape that connects multiple positioning holes 5a provided at different positions in the vertical direction Z, and is provided so that the minimum width of the continuous hole is larger than the diameter of the shank 2b. With this configuration, the piping support 10 of the present invention can be passed between the multiple positioning holes 5a while the shank 2b is inserted into the continuous hole 5. Therefore, the pipe support 10 of the present invention can reduce the number of times that the shank 2b of the fastener 2 is inserted and removed by the number of boundaries between the positioning holes 5a.

[0136] In addition, in the piping support base 10 of the present invention, the anti-slip piece 1 has an axial hole 1a through which the axial portion 2b of the fastener 2 passes, and the positioning hole 5a is formed so that at least a portion of the outer periphery of the anti-slip piece 1 can fit into it. With this configuration, the pipe support 10 of the present invention can fit the slippage prevention pieces 1 into each positioning hole 5a of the continuous hole 5 with the shaft portion 2b passing through the shaft hole 1a. Furthermore, the pipe support 10 of the present invention can prevent the slippage prevention pieces 1 fitted into the continuous hole 5 from moving to another positioning hole 5a because at least a part of the outer periphery of the slippage prevention pieces 1 can fit into the positioning holes 5a. Therefore, in the piping support base 10 of the present invention, the anti-slip piece 1 fills the gap between the peripheral surface of the shaft portion 2b and the continuous hole 5, thereby preventing the position of the shaft portion 2b relative to the base side flat plate portion 32 or the receiving side flat plate portion 22 in which the continuous hole 5 is provided from shifting in the in-plane direction of the base side flat plate portion 32 or the receiving side flat plate portion 22.

[0137] In this way, the pipe support base 10 of the present invention reduces the effort required for adjusting the height of the pipe H by allowing the shaft portion 2b of the fastener 2 to slide between the positioning holes 5a while remaining inserted into the continuous hole 5, and after the work is completed, the anti-slip piece 1 prevents the fastener 2 from shifting in the in-plane direction of the base side flat plate portion 32 or the receiving side flat plate portion 22 in which the continuous hole 5 is provided. Therefore, the pipe support 10 of the present invention does not require spacers or multiple support frames of different heights, which reduces the amount of work required for installation. Furthermore, by using the pipe support 10 of the present invention, the time required for adjusting the height of the pipe H can be reduced, thereby saving labor and reducing facility construction costs.

[0138] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, although the top plate portion 21 of the receiving material 20 in the above-described embodiment has a flat plate shape, the shape of the top plate portion 21 of the receiving material 20 of the present invention is not limited to this. For example, the top plate portion 21 of the receiving material 20 of the present invention may have a curved surface that curves downward in the center in the lateral direction X. With this configuration, the curved surface follows the curvature of the lateral surface h of the pipe H, thereby enabling the pipe H to be supported more stably. [Explanation of symbols]
