Description

[Technical Field]

[0001] The present invention relates to a support member for a structure used in a folded-plate roof or the like in various buildings, and to a fixing structure for the support member to the structure. [Background technology]

[0002] In various buildings, folded plates formed by folding metal sheets into a corrugated shape, so-called folded-plate roofs, are used as roof materials. Various equipment such as solar panels and relay boxes may be fixed on top of these folded-plate roofs. Generally, the multiple folded plates that make up a folded-plate roof are connected to each other via seams (caulkings) formed by plastically deforming the edges of the metal plates. When fixing various equipment on top of a folded-plate roof, for example, as shown in Patent Document 1, a support member is used that has clamps that clamp the seams from both sides. A frame is attached to the top of the support member fixed to the seams, and various equipment is attached to the frame. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-197442 Summary of the Invention [Problem to be solved by the invention]

[0004] In the support member of Patent Document 1, the first and second clamping members that clamp the seam portion from both sides are fastened and fixed by horizontal bolts, and the frame (the member to be fixed) is supported by another bolt extending upward from the first clamping member. Therefore, when attaching the support member to a folded-plate roof, it is necessary to leave a large gap between the bottom ends of the first and second clamping members. This makes the installation of the support member complicated.

[0005] Therefore, an object of the present invention is to make it easy to attach a support member to a structure such as a folded plate roof to the structure. [Means for solving the problem]

[0006] A support member for a structure is adopted, which is used to fix a device to a structure having a protruding portion, and is provided with a clamping portion that clamps the protruding portion from both sides along one direction, and a fixing means for fixing the device, wherein the protruding portion is a ridge extending in another direction intersecting the one direction, and the clamping portion has a slit extending in the other direction at its bottom facing the structure, and a retaining portion that prevents the protruding portion that has entered the slit along the other direction from escaping out of the slit (Configuration 1).

[0007] In configuration 1, the clamping portion has a pair of side portions facing each other in the one direction and a pair of end face portions connecting both ends of the side portions in the other direction, and a configuration can be adopted in which the anti-slip portion is provided on the end face portions (configuration 2).

[0008] In configuration 1 or 2, the structure is a folded-plate roof, and the protruding portion has a rising portion that stands at the top of the folded-plate roof and a bulging portion that is provided at the end of the rising portion and is wider in one direction than the rising portion, and the retaining portion can be configured to engage with the bulging portion to prevent the protruding portion from falling out of the slit (configuration 3).

[0009] In any one of configurations 1 to 3, a configuration can be adopted in which the clamping portion is provided with a first shaft that is inserted into the clamping portion, and a reinforcing member through which the first shaft is inserted, the fixing means is provided on the reinforcing member, and the reinforcing member is movable in the axial direction of the first shaft relative to the clamping portion (configuration 4).

[0010] In the configuration 4, a configuration can be adopted in which an elastic member is disposed between the reinforcing member and the clamping portion to bias the reinforcing member in the other direction (configuration 5). [Effects of the Invention]

[0011] According to the present invention, the support member for a structure can be easily attached to the structure. [Brief explanation of the drawings]

[0013] An embodiment of the present invention will be described with reference to the drawings. This embodiment relates to a support member 10 for a structure (hereinafter simply referred to as the support member 10) used to secure various equipment (various devices) such as solar panels to a folded-plate roof (structure) 1 used as a roofing or ceiling material in various buildings such as warehouses and factories, and a support structure for various equipment to a structure using the support member 10.

[0014] The overall configuration of the support member 10 of the first embodiment is shown in Figures 1 and 2, and the state in which the support member 10 is attached to the folded-plate roof 1 is shown in Figure 3. Also, Figure 4 shows the procedure for attaching the support member 10 to the folded-plate roof 1, and Figure 5 is an exploded view showing the state before the clamping part 20, which is the main body of the support member 10, is manufactured.

[0015] As shown in FIG. 3, the folded-plate roof 1 is a so-called folded-plate roof, constructed by bending a metal plate into a corrugated shape. Its shape consists of a top section 3 with a horizontal plate surface and a bottom section 5 with a similarly horizontal plate surface, alternately connected by inclined sections 4, resulting in a large number of parallel, corrugated sections in cross section. The connections between the top section 3 and the inclined sections 4, and between the bottom section 5 and the inclined sections 4, are the folding points of the metal plate, resulting in an overall structure with alternating peaks and valleys. As shown in FIG. 3, the folded-plate roofs 1 are connected in the width direction via protrusions 2 (hereinafter referred to as seam sections 2 in the embodiment) formed by crimping the edges of the metal plate by plastic deformation. The seam sections 2 are ridges that protrude upward longitudinally along the entire length of the folded-plate roof 1. Furthermore, the folded-plate roofs 1 are connected in the longitudinal direction by overlapping the peaks and valleys of adjacent folded-plate roofs 1 with bolts that pass through the overlapping portions and nuts that are screwed onto the bolts. A folded plate roof 1 is supported by beams (not shown) of a building or the like.

[0016] The width of the peak 3 and bottom 5, the difference in elevation between the peak 3 and bottom 5, the angle of inclination of the inclined portion 4, etc. are set arbitrarily according to the specifications of the folded-plate roof 1. Hereinafter, the parallel direction of the peaks and valleys will be referred to as the width direction (one direction) of the folded-plate roof 1, and the direction in which the peaks and valleys extend will be referred to as the longitudinal direction (other direction) of the folded-plate roof 1. Multiple folded-plate roofs 1 are used by being connected together in the width direction and longitudinal direction. The width and length of one folded-plate roof 1, and the number of repetitions of the peaks and valleys, are set appropriately according to the specifications.

[0017] 1 and 2, the support member 10 has clamping parts (clamping members) 20 that clamp the seam portion 2 of the folded-plate roof 1 from both sides along one direction. The support member 10 also has fixing means 70 for fixing various pieces of equipment.

[0018] In this embodiment, the fixing means 70 is provided on the reinforcing member 40 connected to the clamping unit 20. The fixing means 70 includes a bolt shaft 71 that passes through the reinforcing member 40 in the vertical direction, and a nut 72 that is screwed onto the male thread of the bolt shaft 71 (see FIG. 3). The bolt shaft 71 is inserted into a hole in an angle member 74, and the nut 72 is tightened via a washer 73, thereby fixing the angle member 74 onto the folded-plate roof 1. Various equipment is fixed to the angle member 74.

[0019] 1 and 2, the clamping unit 20 has a pair of side surfaces 22, 23 and end surfaces 21, 21 that close both ends of the pair of side surfaces 22, 23. This makes the clamping unit 20 a frame-like member that is rectangular in plan view. The clamping unit 20 also has a bottom 26 that faces the top 3. The bottom 26 is connected to the lower ends of the pair of side surfaces 22, 23 and the lower ends of the end surfaces 21, 21 via fold lines.

[0020] In this embodiment, the clamping portion 20 is formed by bending a flat plate-like member shown in Fig. 5 by press working or the like. The reinforcing member 40 is also formed by bending a flat plate-like member by press working or the like.

[0021] As shown in Figure 3, the shape of the seam portion 2 in this embodiment includes a rising portion 2a that stands on the top 3 of the corrugated roof 1, and a bulging portion 2e that is provided at the end of the rising portion 2a and is wider in one direction than the rising portion 2a.

[0022] The bulging portion 2e is a hollow portion with a rectangular cross section, and includes an apex 2b that protrudes laterally from the tip (upper end) of the rising portion 2a, a vertical portion 2c that extends from the protruding end of the apex 2b toward the apex 3 (lower side), and a folded portion 2d that extends from the end (lower end) of the vertical portion 2c toward the rising portion 2a. The width in one direction of the bulging portion 2e, i.e., the distance from the left side of the rising portion 2a to the right side of the vertical portion 2c in Figure 3, is set to be larger than the plate thickness in one direction of the rising portion 2a. The symbol 2f in Figure 3 is a core material that is held in the seam portion 2 to secure the folded-plate roof 1 to beams (not shown) of a building or the like.

[0023] A slit 28 extending in the other direction is provided in the bottom 26 of the clamping portion 20. Therefore, the bottom 26 is divided into a first bottom portion 26a and a second bottom portion 26b by the slit 28. The slit 28 in the bottom 26 is continuous with the recesses 36 provided in the end surface portions 21, 21 on both sides.

[0024] The inner surface of the recess 36 has a first portion 33 facing the other side surface of the vertical portion 2c (the side surface on the right side in FIG. 3). Furthermore, a retaining portion 27 protruding below the first portion 33 toward the rising portion 2a is provided. The retaining portion 27 elastically presses the vertical portion 2c and the folded portion 2d against the rising portion 2a while appropriately accompanying elastic deformation of the seam portion 2. Here, a protruding end surface 34 of the retaining portion 27 faces the other side surface of the rising portion 2a (the side surface on the right side in FIG. 3), and a rear side surface (upper surface) 35 of the retaining portion 27 faces the surface of the apex 3 side of the folded portion 2d (the lower surface in FIG. 3). The inner surface of the recess 36 also has a second portion 32 facing one side surface of the vertical portion 2c (the side surface on the left side in FIG. 3).

[0025] The seam portion 2 on the folded-plate roof 1 side is designed to fit into these recesses 36 and slits 28. As shown in FIG. 4, the clamping portion 20 is slid in the other direction from the other edge side of the folded-plate roof 1, and the seam portion 2 is inserted into the slits 28 of the bottom portion 26 and the notches 36 of the end surface portion 21, while the clamping portion 20 is moved to a predetermined position relative to the folded-plate roof 1. The seam portion 2 has a bulging portion 2e on the protruding end side that is more bulging than the rising portion 2a on the base side, and the recess 36 has a wider cross section on the inner side (upper side) far from the bottom 26 than on the entrance side (lower side) close to the bottom 26. Therefore, when the seam portion 2 fits into the recess 36, the seam portion 2 is prevented from slipping out of the clamping portion 20.

[0026] In other words, when an external force acts from the angle iron 74 or various equipment in a direction that causes the seam portion 2 to slip out of the slit 28, the rear surface (upper surface) 35 of the anti-slip portion 27 engages with the underside of the bulge portion 2e (underside of the folded portion 2d), thereby preventing the seam portion 2 of the corrugated roof 1 from slipping out of the slit 28 of the clamping portion 20.

[0027] Thereafter, the second shaft 60 is inserted into the hole 25 of the clamping unit 20, and the tip 62 of the shaft portion 61 of the second shaft 60 is pressed against the seam portion 2. In this state, the second shaft 60 is held by the clamping unit 20, thereby more firmly fixing the support member 10 to the folded-plate roof 1. The hole 25 penetrates the side surface portion 22 in the plate thickness direction. In the embodiment, a female thread is formed in the hole 25, and a male thread is formed in the shaft portion 61 of the second shaft 60. Therefore, when the second shaft 60 is screwed into the hole 25 and its tip is brought into contact with the side surface of the protruding portion 2, and the screwing is stopped at a predetermined position, the second shaft 60 is held by the clamping unit 20 at that position. The second shaft 60 may be held by the clamping unit 20 by a screw connection as in the embodiment, or by a joining method such as welding.

[0028] A plurality of second shafts 60 (two in the embodiment) are inserted along the other direction into the clamping unit 20. The number of second shafts 60 can be increased or decreased as appropriate according to the length of the clamping unit 20 in the other direction.

[0029] Furthermore, a first shaft 50 extending in the longitudinal direction (the other direction) of the folded-plate roof 1 is inserted between the end surface portions 21, 21. The first shaft 50 is inserted through a hole 24 in the end surface portions 21, 21. The hole 24 penetrates the end surface portions 21 on both sides in the plate thickness direction.

[0030] The reinforcing member 40 is disposed inside the clamping portion 20. A first shaft 50 is inserted through the reinforcing member 40. As described above, the fixing means 70 is provided on the reinforcing member 40. By using separate members for fastening the seam portion 2 of the folded-plate roof 1 and for supporting various pieces of equipment, the strength of the support member 10 is further increased.

[0031] The reinforcing member 40 includes a top surface portion 41 located above, side surface opposing portions 43 that rise downward from the top surface portion 41 and face the side surface portions 22 and 23, and end surface opposing portions 42 that rise downward from the top surface portion 41 and face the end surface portions 21 and 21. The side surface opposing portions 43 are provided at both ends of the top surface portion 41 in one direction, with a pair of side surface opposing portions 43, 43 protruding downward in parallel. The end surface opposing portions 42 are provided at both ends of the top surface portion 41 in the other direction, with a pair of end surface opposing portions 42, 42 protruding downward in parallel. Therefore, the reinforcing member 40 is a member that forms a downwardly concave shape. The first shaft 50 is inserted through a hole 44 provided in the end surface opposing portion 42. The hole 44 penetrates each end surface opposing portion 42 in the plate thickness direction.

[0032] Because the reinforcing member 40 is supported by the first shaft 50, it can move along the axial direction (other direction) of the first shaft 50 relative to the clamping portion 20. Therefore, when the folded-plate roof 1 thermally expands in another direction due to a temperature rise or the like, even if the clamping portion 20 fixed to the folded-plate roof 1 moves in that direction, the reinforcing member 40 can remain in the position it was in before the thermal expansion, or in a position with a small amount of movement. This reduces the force applied to the folded-plate roof 1. Furthermore, even when an external force acts on the equipment on the folded-plate roof 1 due to wind or the like, the force applied to the folded-plate roof 1 can be reduced by the movement of the reinforcing member 40.

[0033] For example, as shown in Figure 6, when the folded-plate roof 1 moves upward due to thermal expansion, the clamping portion 20 also moves in the same direction, but the reinforcing member 40 does not move to the position shown by the chain line, but remains in the position shown by the solid line. Note that the folded-plate roof 1 is a component with relatively large dimensional errors, and the various equipment placed on it also has large dimensional errors. For this reason, position adjustment by moving the reinforcing member 40 in this way is very effective.

[0034] At this time, the second shaft 60 does not interfere with the movement of the reinforcing member 40. Also, in the embodiment, the reinforcing member 40 is movable in the other direction but not in one direction, but it may be movable in both the other direction and one direction. In this case, the hole 44 formed in the reinforcing member 40 may also be an elongated hole extending in one direction, and the gap (gap in one direction) between the side surface facing portion 43 of the reinforcing member 40 and the side surface portions 22, 23 may be enlarged.

[0035] Additionally, an elastic member 54 that biases the reinforcing member 40 along the axial direction (the other direction) of the first shaft 50 is disposed between the reinforcing member 40 and the clamping portion 20, i.e., between the end face opposing portion 42 of the reinforcing member 40 and the end face portion 21 of the clamping portion 20. The elastic members 54 are provided on both sides of the reinforcing member 40 in the other direction. This makes it easy to return the reinforcing member 40 to the neutral position (the position before the thermal expansion of the folded-plate roof 1) in accordance with changes in the degree of thermal expansion.

[0036] In each of the above embodiments, the clamping portion 20 and the reinforcing member 40 are formed by bending a flat plate-shaped member by press processing or the like, but the manufacturing method for these members is not limited to press processing, and they may also be manufactured by forging, casting, or other methods.

[0037] Furthermore, in each of the above embodiments, the fixing means 70 is provided on the reinforcing member 40, but an embodiment in which the reinforcing member 40 is not used is also conceivable. When the reinforcing member 40 is omitted, for example, as shown in the second embodiment in Fig. 7, a member corresponding to the top surface portion 41 of the reinforcing member 40 can be extended from the clamping portion 20, and the fixing means 70 can be provided on the extended member. In any of the embodiments, the fixing means 70 is not limited to the bolt shaft 71 as shown in Figs. 1 and 7, and other means may be used.

[0038] Furthermore, in the above embodiments, the configuration of the support member 10 of this invention has been described using a folded-plate roof 1 as an example of a roofing or ceiling material for various buildings, but this invention can also be applied to structures other than the folded-plate roof 1. Examples of such structures include roofing or ceiling materials other than the folded-plate roof 1, various wall members, beam members, and column members. In the first to second embodiments, this invention can be used in structures having linear protrusions 2, so-called ribs, on the surface of the members. In this case, various pieces of equipment attached to the structure may be above, to the side, or below the members that make up the structure. [Explanation of symbols]
