Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for supporting piping such as a water supply pipe and a hot water supply pipe.

[0002]

2. Description of the Related Art Generally, when a water supply pipe or a hot water supply pipe is routed in a space under the floor of a building, the water supply pipe or the hot water supply pipe is required to prevent the water supply pipe or the hot water supply pipe from being exposed by water hammer. The place was supported and fixed with support metal fittings attached to the slab concrete and flooring.

[0003]

However, since the support bracket is attached to the slab concrete or the floor material with screws or the like, the mounting operation is complicated and the workability is deteriorated.
Also, the curved portions of the water supply pipes and hot water supply pipes that rise up in the lower floor wall and enter the lower floor space of the upper floor are difficult to support with conventional support fittings, and are usually not supported, For this reason, due to the occurrence of the water hammer, the curved portion may oscillate and hit a floor material or a wall, and noise may be generated.

[0004] In view of the above, an object of the present invention is to provide a pipe supporting device capable of supporting a pipe in a simple and favorable state.

[0005]

In order to solve the above-mentioned problems, a supporting device according to the present invention locks a support band wound around a pipe to the beam by using a bolt hole formed in the beam in advance. By doing so, the pipe is suspended and supported in the underfloor space. More specifically, the support band is inserted into a bolt hole formed in the lower flange of the beam, and is engaged with the lower flange.

Further, the support band is made of resin and has a height adjusting function for adjusting the hanging height of the pipe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 2 shows a header type water supply / hot water supply piping structure in the underfloor space on the first floor of the building. (1) is a main water supply pipe led to the underfloor space (2) on the first floor of the building. The water supply pipe (1) is connected to a water supply header (3) installed in the underfloor space (2). Also, from the water supply header (3), a plurality of branch water supply pipes (4) (4) ... are branched in an octopus foot shape, and these branch water supply pipes (4) (4) ...
The water heater (10) installed on the outer surface of the building outer wall (5) and the kitchen sink (1)
1), toilet (12), washing machine (13), unit bath (14), wash basin (1
5) connected to the corresponding water facilities on the first floor,
Furthermore, as shown in FIG. 3, the user stands up in the pipe space formed on the outer wall of the building (5), is guided to the underfloor space (6) on the second floor, is routed in the underfloor space (6), and is routed there. It is connected to each water supply facility.

From the water heater (10), a main hot water supply pipe (20) is led to the underfloor space (2) and is connected to a hot water supply header (21) installed in the underfloor space (2). Further, from the hot water supply header (21), a plurality of branch hot water supply pipes (22) (22)... Are branched in an octopus foot shape, and these branch hot water supply pipes (22) (22). 4) (4)
In the same way as the above, it is routed in the underfloor space (2) on the first floor, and is connected to the faucets of the corresponding water facilities such as the kitchen sink (11), the unit bath (14), and the washbasin (15).

As shown in FIG. 4, each of the pipes (1), (4), (20) and (22) has an inner pipe (2) made of cross-linked polyethylene or polybutene.
3), an outer tube made of foamed polyethylene with heat insulation function (24)
The flexible resin pipe is made by coating the pipes, so that flexible pipes can be provided such that pipes (1), (4), (20), and (22) can be piped while being bent. Has become.

In the above header type water supply / hot water supply pipe structure, each main pipe (1) (20) or branch pipe (4) (22).
In order to prevent the water hammer from being exposed with the occurrence of the water hammer, it is supported and fixed as follows.

That is, as shown in FIG. 3, each of the main pipes (1) (20) and branch pipes routed in the underfloor space (2) on the first floor.
(4) (22) ... is fixed to the concrete between the soil (31) by a plurality of fixing brackets (30) (30) ..., the vertical portion (32) of the branch water supply pipe (4) rising in the pipe space, A plurality of fixtures (33) are fixed to a base material (34) installed in the pipe space. The curved portion (35) of the branch water supply pipe (4) which enters the underfloor space (6) on the second floor from inside the pipe space is supported by the support beam (40) of the present invention.
The horizontal part (37) of the branch water supply pipe (4) suspended and supported by (36) and routed in the underfloor space (6) on the second floor,
8) (38) ... suspended from the floor material (39).

As shown in FIG. 1, the support band (40) is made of resin, and has a plurality of fold-like projections (41) (41) formed on the back surface thereof at regular intervals in the longitudinal direction. ing. Also,
At one end, a buckle-shaped stopper (42) that meshes with the projections (41) (41) is provided.

A branch water supply pipe (4) using the support band (40).
First, the curved part (35) of the branch water supply pipe (4) that enters the underfloor space (6) on the second floor from inside the pipe space
Then, the support band (40) is wound. And the support band
The other end (43) of (40) is inserted through bolt holes (45), (45)... Formed in the lower flange (44) of the floor beam (36), and a stopper at one end is further inserted. Insert through (42). The bolt holes (45) (45) are formed at predetermined pitches for mounting various members such as ceiling suspension trees, etc.
Use the unused ones.

Thus, the other end (4) can be moved from the stopper (42) to the other end (4).
Stop the stopper (42) and the projection (41) (4
1) are engaged with each other, and the support band (40) is formed in a ring shape and locked to the lower flange (44) to suspend and support the branch water supply pipe (4).
In this suspended state, the stopper (42) at the other end (43)
By adjusting the insertion amount of the branch water supply pipe, the suspension height of the branch water supply pipe (4) can be adjusted by changing the size of the ring.

The present invention is not limited to the above-described embodiment, and it goes without saying that many modifications and changes can be made to the above-described embodiment within the scope of the present invention. For example, it is not only the curved part of the branch water supply pipe but also the horizontal part of the branch water supply pipe, the main water supply pipe, the main hot water supply pipe, the branch hot water supply pipe, the drainage pipe, etc. May be used.

[0016]

As is apparent from the above description, the pipe supporting apparatus of the present invention comprises a supporting band wound around the pipe.
Since the pipe is suspended and supported only by being locked to the beam, workability can be improved as compared with the related art which requires screwing work to soil concrete or floor material. In addition, since the support band is locked to the beam using a bolt hole formed in the beam in advance, there is no need to perform any special processing on the beam, and the pipe can be suspended and supported at low cost. I can do it.

Further, by using the support band, the curved portion of the pipe can be easily supported, and a pipe structure in which the deflection by the water hammer can be reliably prevented can be realized.

Further, the support band is made of a resin that does not rust, can withstand long-term use, and has a function of adjusting the hanging height of the pipe, so that the height of the space under the floor is reduced. The height position of the pipe can be adjusted as appropriate, and the workability is further improved.

In addition, if the support band is hooked to the lower flange of the beam to suspend and support the pipe, the pipe hardly interferes with the beam, and the construction state can be improved.
