Description

[Technical field]

[0001] The present invention relates to a freestanding support leg for rooftop piping, and more particularly to a freestanding support leg for rooftop piping that does not damage a waterproof layer. [Background technology]

[0002] A piping rack as an example of a conventional piping support leg is disclosed in, for example, JP 2019-152265 A (Patent Document 1). According to Patent Document 1, the piping support leg is fixed and fixed to an installation part provided outside. The fixed piping support leg includes a pair of bolts that hold a cross member on which the piping is placed, and the pair of bolts are installed on-site using anchor bolts and are provided so as to rise from the installation part. A waterproof structure is provided around the rising part of the pair of bolts from the installation part.

[0003] On the other hand, in contrast to such fixed support legs, free-standing support legs are also used for rooftop equipment piping. The configuration of such free-standing support legs is shown in FIG. 4. Referring to FIG. 4, the free-standing support leg 30 is provided on two concrete or mortar blocks 33a, 33b arranged on a waterproof layer 36. A gate-shaped steel material consisting of a pair of legs 31a, 31b and a cross member 32 that supports the piping 35 is attached to the blocks 33a, 33b, and the piping 35 is arranged on the gate-shaped steel material. Assuming that the blocks 33a, 33b will move due to wind pressure or the like, rubber sheets 34, 34b are laid under the blocks 33, 33b to prevent the waterproof layer 36 from being damaged by the corners of the lower surfaces of the blocks 33a, 33b.

[0004] [Patent Document 1] Publication No. 2019-152265 (abstract, etc.) Summary of the Invention [Problem to be solved by the invention]

[0005] Conventional free-standing support legs for rooftop piping were constructed as described above. In order to prevent the corners of the bottom surface of the blocks from damaging the waterproof layer, rubber sheets 34a, 34b were laid under the blocks 33a, 33b, which caused problems in terms of labor and costs associated with the rubber sheets. Specifically, rubber sheets are generally 2 to 3 mm thick, and the material costs are added to the support legs. In addition, the blocks 33a, 33b come in a variety of sizes, which causes problems in terms of the time required to check the size of the blocks and cut the rubber sheets. In addition, there is also a problem in terms of the time required to attach the rubber sheets to the bottom surfaces of the blocks.

[0006] There was also the problem of labor and costs involved in laying additional waterproof sheets such as PVC. Specifically, there was the problem of the labor and materials required to lay additional waterproof sheets for cushioning to prevent the migration of plasticizers between the waterproof sheet and the rubber sheet. Another problem was the labor involved in confirming the location of the piping with the equipment contractor in advance.

[0007] Furthermore, transporting the blocks was a heavy task. Each block usually weighed 10 to 20 kg, and there were many of them, so transporting and distributing them was physically demanding. Also, when molding the blocks with mortar, the weight of the mortar and the labor required to pour it into the mold were also a burden.

[0008] The present invention has been made to solve the above-mentioned problems, and has an object to provide a free-standing support leg for rooftop piping that does not incur the cost of rubber sheets. [Means for solving the problem]

[0009] The free-standing support leg for rooftop piping according to the present invention includes a cross member that supports the rooftop piping, a pair of legs that support the cross member, and a base member to which the legs are fixed, the base member being a metal plate.

[0010] Preferably, the base material includes a rectangular plane and a bent portion bent obliquely downward from the rectangular plane.

[0011] The four bent portions bent obliquely downward from the rectangular plane may be separated from each other by slits. Effect of the Invention

[0012] The base material of the rooftop piping support legs is a metal plate, so it will not damage the waterproof layer. Therefore, there is no need to lay a rubber sheet on the underside of the base material.

[0013] As a result, a free-standing support leg for rooftop piping can be provided that does not incur costs associated with rubber sheets. [Brief description of the drawings]

[Diagram 3] FIG. [Figure 4] FIG. 11 is a perspective view showing the configuration of a conventional stand-type support leg. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a free-standing support leg 10 for piping according to an embodiment of the present invention. Referring to FIG. 1, the free-standing support leg 10 for piping according to an embodiment of the present invention is installed by placing it on a waterproof layer 25. The free-standing support leg 10 for piping includes a rectangular metal base member 12 serving as a foundation, a pair of support legs 11a, 11b consisting of threaded rods spaced apart from each other on the base member 12, a horizontal member 17 serving as a pipe support portion provided at the upper end of the pair of support legs 11a, 11b, and an intermediate member 18 provided at the intermediate portion between the base member 12 and the horizontal member 17 of the pair of support legs 11a, 11b, and the pair of support legs 11a, 11b, the horizontal member 17, and the intermediate member 18 constitute a gate-shaped steel member supporting the pipe 20.

[0016] The base material 12 has a rectangular shape, and its four sides are bent downward at obtuse angles to form inclined portions 12a, 12b, etc. This prevents the base material 12 from damaging the waterproof layer on which the free-standing support leg for piping 10 is placed, and increases the rigidity of the base material 12.

[0017] The pair of support legs 11a, 11b are attached to the base material 12 by a nut 13 fixed onto the base material 12 by welding or the like, and a double nut 15 provided on the nut 13.

[0018] The cross member 17 is fixed to a pair of support legs 11a, 11b with nuts 20a, 20b, and the intermediate member 18 is also fixed to a pair of support legs 11a, 11b with nuts 21a, 21b, thereby allowing the vertical positions of the cross member 17 and the intermediate member 18 to be adjusted.

[0019] Fig. 2 is an enlarged view showing a state in which one of the support legs 11a is fixed to the base material 12. Referring to Fig. 2, a nut 13 is fixed onto the base material 12, and the support leg 11a is fixed thereto with a double nut 15. As described above, the base material 12 has a rectangular shape, and the four sides are bent downward to form the inclined portions 12a to 12d. The same is true for the support leg 11b.

[0020] In order to make it easier to bend the inclined portions 12a to 12d, the inclined portions 12a to 12d are separated from each other by slits 19a to 19d, which also function as drainage holes for rainwater.

[0021] Fig. 3 is a cross-sectional view of the portion indicated by the arrow III-III in Fig. 2. As shown in Fig. 3, the base material 12 is placed on the waterproof layer 25 at the tips of the folded, inclined portions 12a to 12d.

[0022] As described above, in this embodiment, the base material on which the gate-shaped steel material rests is made of a metal plate, so the base material does not damage the waterproof layer and a rubber sheet is not required on the underside of the base material, thereby eliminating the labor and costs associated with rubber sheets.

[0023] In addition, by omitting the rubber sheet, there is no need to install additional waterproof sheets such as PVC sheets, which reduces the labor and costs involved.

[0024] Furthermore, the base material is a metal plate that is lightweight at less than 1 kg, reducing the physical strain on workers when transporting it.

[0025] In the above embodiment, the base material is described as being made of metal, but the present invention is not limited to this and may be made of, for example, a GRC plate.

[0026] Although the embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to the illustrated embodiment. Various modifications and variations can be made to the illustrated embodiment within the same scope as the present invention or within an equivalent scope. [Industrial Applicability]

[0027] According to the present invention, a free-standing support leg for rooftop piping can be provided which does not incur costs associated with rubber sheets, and can therefore be advantageously used as a free-standing support leg for piping. [Explanation of symbols]
