Description

Piping support device for construction piping duct

The present invention relates to a pipe support device for a pipe duct formed in an intermediate slab of a multi-story building, and more particularly, to an improved design for Utility Model Registration Application No. 96-22268, which is the applicant's prior application.

The electoral draft is composed of two semicircular band bodies facing the pipe support to cover the pipe with a wide contact surface over the entire circumference, and has a support flange at the bottom of the band-like support, and supports the pipe with bolts and nuts. It is fastened to the main surface and fastened to the building slab with anchor bolts to secure the pipes with solid support force, while the support pads are fixed to the building slabs, while the rubber pads cover the entire area between the contact surfaces of the support pipes and the building slabs. To prevent the occurrence of electrical corrosion and to prevent the vibration noise of the pipe line from being transferred to the building slab, and to support the pipe at the correct position in the center of the duct hole, thereby omitting the entire space between the duct hole and the pipe. By forming so that it can be insulated without insulation, It is formed to improve the problem of the pipe support device.

However, such a preliminary draft is basically blocked by leakage due to electrical corrosion and prevents the vibration noise of the pipe line from being transmitted to the building slab, and leaves no unfinished portion of the insulation throughout the pipe duct hole and the outer circumferential surface of the pipe. On the other hand, when the pipe support is formed of synthetic resin, the composition of the rubber pad is unnecessarily complicated, and the manufacturing and assembly, installation and construction costs are high. Even when the flange is attached to the building slab, anchor bolts are fixed on the surface of the building slab and the flange bolts are fastened to the anchor bolts. Therefore, the process of placing anchor bolts on the building slab is cumbersome, and anchor bolts are placed on the slab. The strength of the broken part and the part is easily broken. Another problem with the old self-flowing and can not securely support the pipe as a result was displayed.

It is an object of the present invention to improve the problems of the foregoing prior application.

The present invention having such a purpose is to form a pipe support itself formed of a semi-circular band body made of synthetic resin, while inserting a rubber pad only between the both ends of the band body in which the bolt fastening groove is formed, and the pipe paper in the building slab. Even when attaching the earth flange, the pipe support is fastened to the inner edge of the pipe duct hole by a hook-type anchor bolt and nut having a bent end through a pipe positioning hole provided in the flange, and the fastening of the present invention is accomplished. It is intended to achieve the purpose of the bar, the present invention is described below by the drawings.

1 to 4, two pipe supports 1a, 1b and a pipe support 1a, ( Rubber pads (2a) and (2b) attached to the inner surface of the bolt fastening portion of the facing (b) and the fastening bolts (3a) and nuts (3b) and end fastening washers (19) and anchor bolts (4) for fastening them Each semicircular piping support 1a, 1b is comprised of the nut 4b, and the semicircular band body 5 and the flange 6 extended outward from the lower end of the band body 5 are formed, Both ends of the band body 5 are formed with bolting grooves 7a and 7b having a step 8 at one outer edge thereof, and selectively fixes the transverse pipes to the center of the flange 6 as necessary. The bolt fastening groove 9 and the pipe position alignment hole 12 for forming the same are the same as those of the applicant's original draft. Particularly special in the above is that both ends of the band body 5 formed with the bolt fastening grooves 7a and 7b while the pipe supports 1a and 1b made of the semicircular band body 5 are formed of synthetic resin. Only insert the rubber pads 2a and 2b through which the bolt fastening holes 11a and 11b are interposed therebetween, and the pipe position alignment holes drilled through the flanges 6 of the pipe supports 1a and 1b. 12) the anchor bolt 4 having the bent end 4a is fastened with the fastening nut 4b through the washer 13 to attach the pipe supports 1a and 1b to the building slab 14. It is formed.

In the figure, reference numeral 15 denotes a pipe duct film for forming a pipe duct hole, 16 pipe duct hole, 17 pipe, and 18 heat insulating material.

According to the present invention configured as described above, when the pipe 17 is a standing pipe, the pipe 17 is piped into the pipe duct hole 16 provided in the building slab 14, and the pipe supports 1a and 1b made of synthetic resin. Attach the semicircular band bodies 5 on both sides to the outer circumferential surface of the pipe 17 with the rubber pads 2a and 2b interposed therebetween, and then attach the bolting grooves 7a, 7b and the washer 19. The cross section of the pipe duct hole forming film 15 for forming the pipe duct hole in the center of the hole is provided by tightening the fastening bolt 3a and the nut 3b through the pipe positioning hole 12 provided in the flange 6. Anchor bolts (4) are formed through bolting holes formed between the pipe fitting holes (12) and the pipe duct holes (15) for forming the pipe duct holes after the positions of the supports (1a) and (1b) are positioned. The bent end portion 4a of the bent portion so that the bent end portion 4a is caught by the pipe duct hole 16 edge of the slab 14, and the threaded anchor bolt is formed. When the nut 4b is tightened with the washer 13 interposed at the other end of the pipe 4, the pipe supports 1a and 1b are stably fixed to the slab 14, and the pipe 17 is secured. It has a large contact area and is tightly fixed between the two semicircular band bodies 5 of the pipe supports 1a and 1b so that the fluid from the pump in the pipe 17 may be vibrated or impacted due to pressure or water hammer. Even if this is applied, the position of the pipe 17 is stably fixed without deviation or deformation from the designated position, and the position of the pipe 17 piped in the pipe duct hole 16 is also the center of the hole 16. The heat insulating material 18 can be constructed with a uniform thickness over the entire circumferential surface between the duct hole 16 and the pipe 17, and the heat insulating construction can be ensured.

At this time, the step 8 formed in any one of the bolting grooves 7a and 7b of the supports 1a and 1b is used to fix the position of the head of the fastening bolt 3a. It is not required, it is fixed stably to tighten the nut (3b) with a tool only on the opposite side to be able to simply complete the fastening.

On the other hand, in the present invention, the band member 5 of the above-described pipe supports 1a and 1b is formed of an electrically insulating synthetic resin, and faces both ends of the bolts 3a and nuts 3b fastened by the fastening bolts 3a and nuts 3b. Rubber pads (2a) and (2b) are interposed between the parts to not only completely insulate them, but also to generate vibrations or noise generated by fluid pressure or water hammer caused by pump pressure in the pipe 17. By preventing the transmission to (14), it is possible to prevent the damage, vibration or noise pollution of the pipes due to electrical corrosion.

Therefore, according to the present invention as described above, since the piping is more stably supported and fixed in the piping for the building piping duct, and electrical corrosion is prevented, the reliability of the piping construction is improved, so that there is no defect, especially in the piping. By absorbing and absorbing vibrations or noises, it is possible to effectively prevent vibrations and noise pollution.

Moreover, according to the present invention, the insulation can be constructed with a uniform thickness over the entire outer circumference without the portion of the pipe which is piped in the pipe duct hole, and the insulation is not formed. .

In addition, according to the present invention, as the pipe support is formed of synthetic resin, the configuration of the rubber pad is extremely simplified, so that the manufacturing and assembly and installation costs for the electric insulation structure and the vibration noise absorbing structure may be inexpensive, and the flange of the pipe support may be reduced. When attaching to a building slab, it is possible not to pour anchor bolts on the slab surface but to attach anchor bolts with bent ends to the pipe duct hole through the pipe alignment holes. It does not damage the installation, and installation and installation also shows an improved effect that becomes simpler.
