DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply / hot water supply header fixing device used in header construction piping.

[0002]

2. Description of the Related Art In recent years, a water supply system employing a header construction method in which a branch pipe branched from a main water supply pipe or a main hot water supply pipe in a ladder-like manner via a header is connected one-to-one to a faucet of each water circulating facility.・ Hot water supply piping is becoming widespread. In such a header construction method, the number of connection points is small, so that water leakage due to poor construction can be remarkably suppressed, and the flow rate change is small at the time of simultaneous use of the water circulating equipment, so that stable water supply and hot water supply are possible.

[0003]

In the conventional header construction method, it is common to fix the header to a header panel mounted inside the wall. However, in this case, since a space for installing the header must be secured inside the wall, the wall is thickened, which has affected the architectural plan.

[0004] Further, since the header is directly fixed to the header panel, when connecting the main pipe or the branch pipe to the header, the header panel adjacent to the header becomes an obstacle,
Workability was poor.

[0005] In view of the above, it is an object of the present invention to provide a fixing device capable of fixing a header for water / hot water supply without affecting a building plan and improving workability. I do.

[0006]

In order to solve the above-mentioned problems, a fixing device of the present invention fixes an L-shaped member to a beam, a floor material, or the like in an underfloor space, and attaches an L-shaped member to a vertical piece of the L-shaped member. The header is fixed by attaching both ends of the U-shaped member externally fitted to the header.

In addition, bolts formed at both ends of the U-shaped member are inserted into bolt insertion holes formed in the vertical piece of the L-shaped member, and nuts screwed to these bolts are tightened, so that the L-shaped member is formed. The header was held between the vertical piece and the U-shaped member.

Furthermore, a horizontal piece of an L-shaped member is attached to the lower flange of the beam, and a U-shaped member is attached to a vertical piece that stands up from the horizontal piece and faces the web of the beam, thereby aligning the header with the beam. I tried to fit it inside the beam.

From the water supply header (3), a plurality of branch water supply pipes (4) (4) are branched in an octopus-like manner, and these branch water supply pipes (4) (4) are formed in an underfloor space ( Water heater (10), kitchen sink (11), toilet (12), washing machine (13), unit bath (1)
4), the washstands (15) are connected to the corresponding water taps on the ground floor.

Also, a space under the floor (1) from the water heater (10) to the first floor.
The main hot water supply pipe (20) led to the hot water supply header (21) installed in the underfloor space (1) on the first floor.

From the hot water supply header (21), a plurality of branch hot water supply pipes (22) (22) are branched in an octopus-like manner, and these branch hot water supply pipes (22) (22). (4) Underfloor space like (4)…
It is routed at (1) and is connected to the faucets of the corresponding water circulating facilities such as the kitchen sink (11), the unit bath (14), and the basin (15). In addition, each header (3) (2
1) is fixed to the slab concrete (5).

On the second floor, each header (3) (21)
Installed in the underfloor space (6) on the second floor, each main pipe (2) (20) and each branch pipe (4) (22) ... are routed in the underfloor space (6) on the second floor. It has almost the same piping structure.

In such a header type water supply / hot water supply pipe, each of the headers (3) and (21) on the second floor, as shown in FIG. 1 and FIG.
It is fixed to the floor beam (41) of (6). 1 and 2
1 shows only fixing of the water supply header (3), the hot water supply header (21) is similarly fixed.

The fixing device (30) comprises a metal L-shaped member (31) fixed to the floor beam (41) and a metal U-shaped member (32) for holding the headers (3) and (21). It is composed of L-shaped member (31)
Consists of a strip-shaped horizontal piece (33) and a strip-shaped vertical piece (34) rising vertically from one end of the horizontal piece (33),
At the other end of the horizontal piece (33), a bolt through hole (35) is formed, and in the vertical piece (34), a pair of upper and lower bolt insertion holes (36) (36)
Are formed. The U-shaped member (32) is formed by forming bolts (37) and (37) at both ends of a metal round bar curved in a U-shape.

The fixing of the water supply header (3) using the fixing devices (30) (30) is performed as follows. First,
The two L-shaped members (31) (31) are fixed to the lower flange (42) of the floor beam (41) at appropriate intervals. Each L-shaped member (31) is attached so that the horizontal piece (33) faces the web (43) with the vertical piece (34) protruding from the upper surface of the lower flange (42) of the floor beam (41). Then, it is placed on the upper surface of the lower flange (42). 38) is inserted, and a nut (39) is screwed into the tip of the mounting bolt (38) from below and tightened. The bolt holes are formed at predetermined pitches for mounting various members, such as ceiling suspension trees, and unused ones are used.

Then, U-shaped members (32) and (32) are externally fitted near both ends of the header (3), and these U-shaped members (32) and (3) are fitted.
The bolts (37) (37) of 2) are fixed to the floor beam (41) at appropriate intervals by bolt insertion holes of the vertical pieces (34) (34) of the L-shaped members (31) (31). (36) (36)… Insert them into the bolts (37) (3
7) Screw nuts (40) and (40) on the tip of
The header (3) is connected to the vertical pieces (34) (34) of the L-shaped members (31) (31) and U
The header (3) is fixed to the floor beam (41) by being sandwiched between the mold members (32) and (32). In the above, after fixing the L-shaped members (31) and (31) to the floor beam (41),
Although the mold members (32) and (32) are attached to the L-shaped members (31) and (31), after attaching the U-shaped members (32) and (32) to the L-shaped members (31) and (31), The L-shaped members (31) (31) may be fixed to the floor beam (41).

The header (3) (2) thus fixed
A main water supply pipe (2) and a main hot water supply pipe (20) are connected to a connection port (not shown) at one end of the header (3) (2).
Connection ports (5) formed at intervals in the axial direction on the outer periphery of 1)
0, (50), ..., branch water supply pipes (4), (4) ... and branch water supply pipes (22, 22)
... are connected. At this time, the connection ports (50) (50)
When facing the side opposite to the web (43) side of 1), the floor beam (41) does not interfere and the workability is good.

The present invention is not limited to the above embodiment, and it goes without saying that many modifications and changes can be made to the above embodiment within the scope of the present invention.

For example, the fixing device of the present invention may be used not only for fixing a header to a floor beam but also for fixing to the back surface of a floor material such as ALC. In this case, the horizontal piece of the L-shaped member is fixed to the floor material.
Further, it may be used for fixing a sub-header provided under the upper floor of a detached house.

[0023]

As is clear from the above description, by using the fixing device for a water / hot water supply header according to the present invention, the header is installed in the underfloor space where the space is sufficiently secured, thereby affecting the building plan. It is possible to realize piping that does not give.

Further, since the U-shaped member externally fitted to the header is attached to the vertical piece of the L-shaped member fixed to the beam or the floor material, the header is fixed while being separated from the beam or the floor material. Therefore, the connection of the main pipe and the branch pipe to the header can be performed without interfering with the beams and the floor material, and the workability can be improved.

Further, since the header is held between the vertical piece of the L-shaped member and the U-shaped member, the header can be securely fixed.

In addition, since the header is fixed so as to be accommodated in the beam holder while following the beam, the header does not protrude much from the beam, and there is a problem that the header interferes with other piping and wiring. Can be prevented.
