Description

[Technical Field]

[0001] The present invention relates to a pipe support device and a pipe support tool for a pipe having a slit (crack) for accommodating wiring or piping materials. [Background technology]

[0002] Conventionally, there has been a closure that holds closed a longitudinally continuous crack in a protective tube that houses wiring and piping materials (see, for example, Patent Document 1). As shown in Fig. 20, a protective tube 21 has a crack 21a, and a closure 22 has an engaging portion 23 that engages with a groove portion 21b of the protective tube 21, and is formed in a roughly C-shape so as to cover the protective tube 21 over 180° in the circumferential direction. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-248364 Summary of the Invention [Problem to be solved by the invention]

[0004] In the conventional closure 22, the crack 21a of the protective pipe 21 has a small gap even when closed, and so by placing the crack 21a downward, it is possible to use the crack 21a as a drain port for draining rainwater or the like that has entered the protective pipe 21 to the outside. However, when the protective pipe 21 is placed on a mounting surface, if the crack 21a comes into contact with the mounting surface, drainage may be impeded. Even if drainage is successful, the protective pipe 21 may block the flow, causing a risk of puddles forming around the protective pipe 21.

[0005] This invention has been made to solve the above-mentioned conventional drawbacks, and its purpose is to provide a pipe support device and pipe support tool that can easily drain rainwater and other water that has entered the pipe. [Means for solving the problem]

[0006] In order to achieve the above object, the pipe support device and pipe support tool according to the present invention have the following configuration: The present invention The pipe support device according to the present invention comprises a pipe with a continuous slit formed in the axial direction and a pipe support tool that supports the pipe in a state where it is suspended above the installation surface. The pipe can accommodate wiring and piping materials inside through an opening in the slit. The pipe support tool includes a pipe holding part that holds the pipe and support legs that are placed on the installation surface to position the pipe above and away from the installation surface. The pipe holding part has a pair of arms that are positioned opposite each other and have an opening between their tips that receives the pipe, and that sandwich and hold the received pipe, and a connecting part that connects the pair of arms. The pair of arms press against the outer surface of the pipe on the side perpendicular to the side where the slit is located, thereby preventing the slit from widening.

[0007] According to this pipe support device, the pipe support tool includes a pipe holder and support legs that position the pipe above and away from the installation surface. The pair of arms of the pipe holder press against the outer surface of the pipe perpendicular to the slit, preventing the slit from opening. Furthermore, by positioning the pipe above and away from the installation surface with the support legs, rainwater or the like that has entered the pipe can be discharged through the gap in the slit, allowing the discharged rainwater or the like to flow unobstructed by the pipe.

[0008] Also, The present invention In the tube support device, the pair of arms are formed so that the opposing gap between them is narrower than the corresponding gap between the outer surfaces of the tubes they hold, and when the tubes are pushed through the open portion, the tubes slide relative to the pair of arms and move toward the rear. Configuration is suggested .

[0009] Also, The present invention In the pipe support device, the pipe is a corrugated pipe having concave and convex portions alternately arranged on its outer surface in the axial direction. The pair of arms enters the concave portions of the corrugated pipe and presses against the concave portions. Configuration is suggested As a result, the pair of arms are sandwiched between the convex portions on the outer surface of the pipe that will become the corrugated pipe, and the pipe support prevents the pipe from shifting in the axial direction.

[0010] Also, The present invention In the pipe support device of the above, when the pair of arms press the recess of the pipe, the pipe support tool is entirely contained within the maximum width of the pipe in the pressing direction. Configuration is suggested This prevents the pipe supports from getting in the way when multiple pipes are installed adjacent to each other.

[0011] Also, The present invention In the pipe support device of the above, the pair of arms have their tip sides extending beyond the axis of the held pipe. Configuration is suggested .

[0012] Also, The present invention In the pipe support device of the present invention, a slip-out prevention portion that protrudes inward is provided on the tip side of at least one of the pair of arms to prevent the held pipe from slipping out of the open portion, and the pipe can pass through the slip-out prevention portion by deforming inward. Configuration is suggested .

[0013] Also, The present invention In the pipe support device, a plurality of types of support legs having different orientations are provided as the support legs, and one type of support leg among the plurality of types of support legs is selectively placed on the installation surface. Configuration is suggested Therefore, the orientation of the pipe support tool, and therefore the orientation of the pair of arms, can be changed by selecting which of the multiple types of support legs is selected, which allows the pipe to be inserted between the pair of arms from multiple directions around the outer periphery of the pipe, improving the workability of pipe placement.

[0014] Also, The present invention In the tube support device of the present invention, the tube holder has a position maintaining means for maintaining the tube in a specific position around the circumference of the tube. Configuration is suggestedThis position maintaining means makes it easy to prevent rotation due to twisting of the pipe and to maintain the cut in a predetermined position around the circumference of the pipe. Furthermore, when the pipe support is placed on a laying surface while holding the pipe, the support legs can be kept facing the laying surface, making the pipe placement work easier.

[0015] Also, The above configuration In the above, the tube holder can position the tube at any position around the circumference of the tube. Configuration is suggested .

[0016] Also, The present invention In the pipe support device, the pipe support tool is entirely made of metal wire or rod material. Configuration is suggested By constructing the pipe support from wire and rod material, it can be easily manufactured, and by making the pipe support from metal, it has high strength and rigidity, and the pipes can be placed on the installation surface in a stable state without shaking.

[0017] Also, The above configuration In the above, the pair of arms extend linearly, and the support legs are provided continuously to the base ends thereof. Configuration is suggested .

[0018] Also, The present invention In the pipe support device, a plurality of support legs are formed, and the support legs are placed on the laying surface at intervals in the left-right direction along the laying surface, perpendicular to the axial direction, and a water channel is formed between the support legs along the axial direction of the held pipe. Configuration is suggested .

[0019] Also, The present inventionThe pipe support according to the present invention supports a pipe having continuous slits formed in the axial direction and capable of accommodating wiring and piping materials through an opening formed by the slits, while maintaining the pipe suspended above the installation surface. The pipe support includes a pipe holding part that holds the pipe and support legs that are placed on the installation surface and position the pipe above and away from the installation surface. The pipe holding part includes a pair of arms that face each other and have an open part between their tips that receives the pipe, sandwiching and holding the received pipe, and a connecting part that connects the pair of arms. The pair of arms press against the outer surface of the pipe on a side perpendicular to the side where the slit is located, preventing the slit from opening. When the pipe is pushed through the open part, the pipe slides relative to the pair of arms and moves toward the rear.

[0020] This pipe support includes a pipe holder and support legs that position the pipe above and away from the installation surface. The pair of arms of the pipe holder press against the outer surface of the pipe perpendicular to the slit, preventing the slit from opening. Furthermore, by positioning the pipe above and away from the installation surface with the support legs, rainwater or the like that has entered the pipe can be discharged through the gap in the slit, allowing the discharged rainwater or the like to flow unobstructed by the pipe. [Effects of the Invention]

[0021] According to the pipe support device and pipe support tool of this invention, the pipe support tool is equipped with a pipe holding portion and support legs that position the pipe above and away from the installation surface, making it easy to drain rainwater and other water that has entered the pipe through slits in the pipe.

[0023] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0024] 1 to 6 show a first embodiment of the present invention. In the drawings, reference numeral 1 denotes a laying surface. 2 denotes a pipe. 3 denotes a pipe support tool that supports the pipe 2 in a state where it is floating above the laying surface 1. 4 denotes a pipe support device consisting of the pipe 2 and the pipe support tool 3.

[0025] The pipe 2 has a slit 2a formed continuously in the axial direction 2b, and wiring and piping material (wiring material or piping material) can be accommodated inside through an opening formed by the slit 2a.

[0026] The pipe support 3 includes a pipe holding portion 5 that holds the pipe 2 and support legs 6 that are placed on the installation surface 1 and position the pipe 2 above and away from the installation surface 1. The pipe holding portion 5 includes a pair of arms 7, 7 that face each other and have an open portion 7a between their tips to receive the pipe 2 and hold the received pipe 2 between them, and a connecting portion 8 that connects the base ends of the pair of arms 7, 7. The pair of arms 7, 7 are designed to prevent the slit 2a in the pipe 2 from opening. That is, the pair of arms 7, 7 press against the outer surface of the pipe 2 on the side perpendicular to the side where the slit 2a is located, preventing the slit 2a from opening. When the pipe 2 is pushed through the open portion 7a, the pipe 2 slides relative to the pair of arms 7, 7 and can be moved toward the rear. In other words, the distance between the pair of arms 7, 7 is narrower than the corresponding distance on the outer surface of the tube 2 that it holds, and when the tube 2 is pushed through the open portion 7a, the tube 2 slides relative to the pair of arms 7, 7 and moves toward the back.

[0027] The distal ends of the pair of arms 7, 7 extend beyond the axis 2c of the held pipe 2. At least one of the pair of arms 7, 7 (both in the illustrated embodiment) is provided at the distal end with an inwardly protruding slip-out prevention portion 7b to prevent the held pipe 2 from slipping out of the open portion 7a. The pipe 2 can pass through the slip-out prevention portion 7b by deforming inward.

[0028] The tube holder 5 also has a position maintaining means 9 that maintains the tube 2 at a specific position around the circumference of the tube 2. The tube holder 5 can position the tube 2 at any position around the circumference of the tube 2.

[0029] In addition, multiple support legs 6 (two in the illustrated embodiment) are formed, and these support legs 6, 6 are placed on the laying surface 1 at a distance from each other in the left-right direction 10 along the laying surface 1, perpendicular to the axial direction 2b of the pipe 2, and a water channel 11 is formed between these support legs 6, 6 along the axial direction 2b of the held pipe 2.

[0030] Specifically, the pipe 2 is made of, for example, a synthetic resin and is a corrugated pipe whose outer surface has alternating recesses 2d and protrusions 2e in the axial direction 2b of the pipe 2. The pair of arms 7, 7 of the pipe support 3 enter the recesses 2d of the corrugated pipe and press against the recesses 2d. With the pair of arms 7, 7 pressing against the recesses 2d of the pipe 2, the pipe support 3 is entirely within the maximum width of the pipe 2 in the pressing direction (the left-right direction 10 in the illustrated embodiment). Specifically, the pipe 2 is a cylindrical corrugated pipe in which the recesses 2d and protrusions 2e are formed in a circular ring shape. As described above, the pipe holder 5 can position the pipe 2 at any position around the circumference of the pipe 2. The position maintaining means 9 is achieved by friction when the pipe holder 5 (the pair of arms 7, 7 and the connecting portion 8 in the illustrated embodiment) contacts the pipe 2.

[0031] Depending on the length of the pipe 2, one pipe support 3 may be provided, or multiple pipe supports 3 may be provided at intervals in the axial direction 2b of the pipe 2. The entire pipe support 3 is made of metal wire or rod material (wire or rod), and in the illustrated embodiment, it is formed by bending a single wire or rod material (wire or rod). The pair of arms 7, 7 extend linearly (or substantially linearly), and the support leg 6 is provided continuous with the base end thereof.

[0032] Specifically, the pipe support 3 has a pair of arms 7, 7 that extend linearly (or substantially linearly) perpendicular to the installation surface 1. The pair of arms 7, 7 are formed with a slight inward curve near their tips, and this curved portion serves as the aforementioned slipout prevention portion 7b. A connecting portion 8 connecting the base ends (lower sides in the illustrated embodiment) of the pair of arms 7, 7 is made up of support legs 6, 6 located on both sides and a main connecting portion 8a connecting the support legs 6, 6. Both support legs 6, 6 are bent in a U-shape, with their inner upper ends continuing to the main connecting portion 8a and their outer upper ends continuing to the arm 7. The main connecting portion 8a is formed in an arc shape following the outer surface of the pipe 2 (more specifically, the recess 2d). Therefore, when the pipe 2 (more specifically, the recess 2d) is placed on the main connecting part 8a with the slit 2a facing downwards, even if a person steps on the pipe 2 and pressure is applied to the pipe 2 from above, the main connecting part 8a (connecting part 8) and the pair of arms 7, 7 eliminate any room for deformation of the pipe 2 and prevent the slit 2a from opening.

[0033] Next, the effects of the pipe support device 4 shown in the first embodiment will be described. The pipe support tool 3 in this pipe support device 4 includes a pipe holding part 5 and support legs 6 that position the pipe 2 above and away from the installation surface 1. The pair of arms 7, 7 of the pipe holding part 5 press against the outer surface of the pipe 2 on the side perpendicular to the side where the slit 2a is located, thereby preventing the slit 2a from opening. By positioning the pipe 2 above and away from the installation surface 1 with the support legs 6, rainwater and other water that has entered the pipe 2 can be drained through the gaps in the slit 2a located below, allowing the drained rainwater and other water to flow unobstructed by the pipe 2. In other words, the pipe support tool 3 includes the pipe holding part 5 and support legs 6 that position the pipe 2 above and away from the installation surface 1, making it easy to drain rainwater and other water that has entered the pipe 2 through the slit 2a in the pipe 2.

[0034] Furthermore, the pipe 2 is a corrugated pipe, and the pair of arms 7, 7 enter and press against the recess 2d on the outer surface of the corrugated pipe. As a result, the pair of arms 7, 7 are sandwiched between the protrusions 2e on the outer surface of the corrugated pipe (pipe 2), preventing the pipe support 3 from shifting in the axial direction 2b of the pipe 2. Furthermore, with the pair of arms 7, 7 pressing against the recess 2d on the outer surface of the pipe 2, the pipe support 3 is entirely contained within the maximum width of the pipe 2 in the pressing direction (left-right direction 10) (i.e., within a dimension not exceeding the maximum width of the pipe 2). Therefore, when multiple pipes 2, 2 are installed adjacent to each other, the pipe support 3 does not interfere with the adjacent pipes.

[0035] The pipe holding portion 5 also has a position maintaining means 9 that maintains the pipe 2 in a specific position around the outer circumference of the pipe 2, and this position maintaining means 9 makes it easy to suppress rotation due to twisting or the like of the pipe 2 and maintain the slit 2a in a predetermined position (for example, a lower position) around the outer circumference of the pipe 2. Furthermore, when the support leg 6 (pipe support 3) is placed on the laying surface 1 with the pipe 2 held by the pipe support 3, the position maintaining means 9 can maintain the support leg 6 facing the laying surface 1 during the placement, making it easy to perform the work of placing the pipe 2.

[0036] The entire pipe support 3 is made of metal wire or rod material (wire or rod). By making the pipe support 3 from wire or rod material (wire or rod), the pipe support 3 can be easily manufactured, and by making the pipe support 3 from metal, the pipe support 3 has high strength and rigidity, so that the pipe 2 can be placed on the laying surface 1 in a stable state without shaking.

[0037] Furthermore, the distal ends of the pair of arms 7, 7 extend beyond the axis 2c of the held pipe 2. Therefore, the arms 7 are long enough to allow the pipe 2 to completely slip out of the open portion 7a, making it difficult for the pipe 2 to come off the open portion 7a. The height position of the pipe 2 can be changed within the range in which the arms 7 extend beyond the axis 2c of the pipe 2.

[0038] Furthermore, the pipe holder 5 can position the pipe 2 at any position around the outer periphery of the pipe 2. This makes it possible to orient the support legs 6 toward the installation surface 1 regardless of the orientation of the slits 2a or even if the pipe 2 is twisted. Furthermore, after attaching the pipe support 3 to the pipe 2 from any direction (for example, from above), the pipe support 3 can be rotated around the outer periphery of the pipe 2 so that the support legs 6 are oriented toward the installation surface 1 (i.e., pointing downward), so the installation direction is not limited and installation is simple.

[0039] 7 to 12 show a second embodiment of the present invention. The pipe support device 4 shown in this second embodiment differs from the first embodiment in the shape of the pipe 2 and the shapes of the support legs 6 and connecting portions 8 of the pipe support 3, but is otherwise substantially similar. Therefore, the following description will focus mainly on the different parts, using the same reference numerals.

[0040] The pipe 2 has a linear portion 2f extending circumferentially along its outer surface. The pipe support 3's pipe holding portion 5 includes a positioning mechanism 9 for maintaining the pipe 2 at a specific position around its circumference. The positioning mechanism 9 includes a restricting abutment 9a that abuts against the linear portion 2f. In the illustrated embodiment, the pipe 2 is made of, for example, synthetic resin and is a corrugated pipe whose outer surface has alternating recesses 2d and protrusions 2e arranged in the axial direction 2b. Specifically, the pipe 2 is a rectangular corrugated pipe with the recesses 2d and protrusions 2e formed in a square ring shape. The pair of arms 7, 7 of the pipe support 3 enter the recesses 2d of the corrugated pipe and press against the recesses 2d. At this time, the pair of arms 7, 7 (more specifically, the pair of arms 7, 7 and the connecting portion 8, described later) abut against the linear portion 2f that forms the square of the recesses 2d, forming the restricting abutment 9a. When the pair of arms 7, 7 press against the recess 2d of the pipe 2, the pipe support 3 is entirely contained within the maximum width of the pipe 2 in the pressing direction (in the illustrated embodiment, the left-right direction 10) (i.e., within a dimension that does not exceed the maximum width of the pipe 2).

[0041] The entire pipe support 3 is made of metal wire or rod material (wire or rod material). A pair of arms 7, 7 extend linearly perpendicular to the installation surface 1, with support legs 6, 6 provided continuous with their base ends. Unlike the first embodiment, the pair of arms 7, 7 do not have anti-slip portions 7b. Both support legs 6, 6 extend straight downward from the base ends of the pair of arms 7, 7, with their lower ends slightly bent inward.

[0042] The connecting portion 8 connecting the base ends (lower sides in the illustrated embodiment) of the pair of arms 7, 7 is formed in a straight line following the outer surface (more specifically, the recessed portion 2d) of the pipe 2. When the pipe 2 (more specifically, the recessed portion 2d) is placed on the connecting portion 8 with the slit 2a facing downward, even if a person steps on the pipe 2 and pressure is applied to the pipe 2 from above, the connecting portion 8 and the pair of arms 7, 7 eliminate any room for deformation of the pipe 2 and prevent the slit 2a from opening. Note that the connecting portion 8 is provided with a protrusion 8b at its central position that bends downward to allow relief for a protrusion 2g (see FIG. 10) provided on the outer surface of the pipe 2. In addition, in the illustrated embodiment, the pipe support 3 is formed from a single wire or rod material (wire or rod material) on each side from the arm portion 7 to the support leg 6, and the wire or rod material (wire or rod material) that forms the connecting portion 8 is welded or otherwise integrated to connect these wire or rod materials (wire or rod material).

[0043] The action and effect of the pipe support device 4 shown in this second embodiment is similar to that of the pipe support device 4 shown in the first embodiment, but since the pipe 2 is a square tube, the position of the pipe 2 around the outer circumference of the pipe 2 is limited relative to the pipe holding portion 5, but the pipe holding portion 5 can support the pipe 2 in at least either orientation with the slit 2a facing downwards or upwards.

[0044] 13 to 19 show a third embodiment of the present invention. The pipe support device 4 shown in this third embodiment is similar to that of the first embodiment except that the pipe 2 is the same and the pipe support 3 is provided with multiple types of support legs 6. Therefore, the following description will focus mainly on the differences, with the same reference numerals used.

[0045] The pipe support device 3 is provided with multiple types (two types in the illustrated embodiment) of support legs 6, 6 that are oriented differently from each other, and one type of support leg from the multiple types of support legs 6, 6 is selectively placed on the laying surface 1.

[0046] The pipe support 3 is entirely made of metal wire or rod material (wire or rod), and in the illustrated embodiment, it is formed by bending a single wire or rod material. The pair of arms 7, 7 extend linearly (including substantially linearly) perpendicular to the installation surface 1. A first support leg 601, which serves as the support leg 6, is provided at its distal end (specifically, extending straight from the distal end), and a second support leg 602, which serves as the support leg 6, is provided at its proximal end. In other words, the first support leg 601 and the second support leg 602 face in opposite directions. The arm 7 has a slip-out prevention portion 7b at its distal end that protrudes inward. Two slip-out prevention portions 7b are provided for each arm 7, spaced apart along its length.

[0047] 13 to 15 show a case where the first support leg 601 is selected as the support leg 6 and the pipe support 3 is oriented with the first support leg 601 facing downward. Figs. 16 and 17 show a case where the second support leg 602 is selected as the support leg and the pipe support 3 is oriented with the second support leg 602 facing downward. Fig. 16 shows a case where the pipe 2 is sandwiched between the arms 7, 7 at the rear of the lower one of the two vertically aligned slip-out prevention parts 7b, 7b, and Fig. 17 shows a case where the pipe 2 is sandwiched between the arms 7, 7 between the two vertically aligned slip-out prevention parts 7b, 7b.

[0048] The connecting portion 8 connecting the base ends of the pair of arms 7, 7 is made up of second support legs 602, 602 located on both sides and a main connecting portion 8a connecting the second support legs 602, 602. Both second support legs 602, 602 are bent into a flattened U-shape, with their inner ends continuing to the main connecting portion 8a and their outer ends continuing to the arms 7. The main connecting portion 8a is formed in an arc shape following the outer surface of the pipe 2 (more specifically, the recess 2d). Therefore, when the second support leg 602 is selected as the support leg 6 and the pipe support device 3 is oriented so that the second support leg 602 is at the bottom, if the pipe 2 (more specifically, the recess 2d) is placed on the main connecting part 8a with the slit 2a facing downwards (see Figure 16), even if a person steps on the pipe 2 and pressure is applied to the pipe 2 from above, the main connecting part 8a (connecting part 8) and the pair of arms 7, 7 will eliminate any room for deformation of the pipe 2 and prevent the slit 2a from opening.

[0049] The action and effect of the pipe support device 4 shown in this third embodiment is similar to that of the pipe support device 4 shown in the first embodiment, but in addition, the orientation of the pipe support tool 3, and therefore the orientation of the pair of arms 7, 7, can be changed by selecting which of the multiple types of support legs 6, 6 (two types in the illustrated embodiment).As a result, when inserting the pipe 2 between the pair of arms 7, 7, the pipe 2 can be inserted from multiple directions around the outer circumference of the pipe 2 (two directions, top and bottom, in the illustrated embodiment), improving the workability of pipe placement.

[0050] In addition, each arm 7 is provided with anti-slip portions 7b, and two of these anti-slip portions 7b are provided for each arm 7, so that even if the pipe 2 comes out of one anti-slip portion 7b, the other anti-slip portion 7b prevents the pipe 2 from coming out, thereby reliably preventing the pipe 2 from coming out. Also, as shown in Figures 16 and 17, by aligning the holding position of the pipe 2 with each anti-slip portion 7b, the height of the pipe 2 relative to the installation surface 1 can be changed.

[0051] The present invention is not limited to the above-described embodiment, and various other modifications are possible. For example, the pipe 2 does not have to be a corrugated pipe, but may be a pipe with a smooth outer surface.

[0052] Furthermore, by placing the slit 2a downward, rainwater and other water that has entered the pipe 2 can be discharged through the slit 2a, but conversely, by placing the slit 2a upward, rainwater and other water that flows or accumulates on the installation surface 1 can be prevented from entering the pipe 2.

[0053] Furthermore, the position maintaining means 9 is not limited to friction (first and third embodiments) or a regulating abutment portion 9a (second embodiment), and the position maintaining means 9 may, for example, be provided with an insertion portion that is inserted into the slit 2a of the tube 2 in the tube holding portion 5 that holds the tube 2.

[0054] Furthermore, the pipe support 3 is not limited to pipes 2 with slits 2a, but can support pipes of the same shape that do not have slits 2a. Furthermore, this pipe support 3 may be used to support a cable by clamping it between the arms 7, 7. [Explanation of symbols]
