It is not permanent, but temporary and will be removed after construction is completed. Therefore, the piping space such as the high-pressure piping 32 and the low-pressure piping 34 is not provided with a dedicated space in many cases. In general, the middle of the piping is clamped to a pipe material of a scaffold, or an elevator room is used. They extended to the upper floors and plumbed to avoid obstacles.

However, in the conventional water supply system, a steel pipe is used as a pipe material, so that a special technique is required for the work of mounting the pipe, and there are some difficulties depending on the mounting place. That is, the connection of the steel pipe
It is performed by wrapping a seal tape around the outer thread of one end of the pipe and screwing it into the inner thread of the other end of the pipe. Therefore, it is difficult to connect them while avoiding obstacles.In addition, the heavy weight of the steel pipe itself makes it difficult to handle, and work at high altitudes is dangerous. There was a problem that it was troublesome. In addition, when the water supply system is removed after the construction is completed, the screw is turned in reverse from the top floor to remove the water supply system. If the part is corroded or rusted, it becomes difficult to remove it, and in some places it may be left unattended without being removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a partial view of a temporary water supply system in building a building according to the present invention.

The pressure reducing valve unit 1 is provided with a short pipe clamp 3 having a handle 3a at the back of the high pressure side T-shaped pipe joint 2.
The open / close valve 4 is connected to one end of the high-pressure side T-shaped pipe joint 2 in the DC direction, and the female side of the union joint 5 is screwed to the lower open end of the T-shaped pipe joint 2 and the open end of the open / close valve 4 respectively. A pressure gauge 6 is connected to the branched open end of the high-pressure side T-shaped pipe joint 2, a low-pressure side T-shaped pipe joint 7 is connected to the open end of the pressure gauge 6, and further a low-pressure side T-shaped pipe joint 7 is connected. Pressure reducing valves 8 and 9 are connected to the branched open end and the open end on the DC side. The connecting valve unit 11 is connected to an on-off valve 4 at one end in the DC direction of a T-shaped fitting 12 having a short pipe clamp 3 with a handle 3a on the back in the same manner as described above, and the T-shaped fitting 12 and the on-off valve 4 are connected.
The female side of the union joint 5 is screwed into each of the two open ends. The T-shaped fitting 12 of the connection valve unit 11 may use the same fitting as the T-shaped fitting 2 of the high-pressure side of the pressure reducing valve unit 1. The branched open end is closed with a plug 11a. However, when it is desired to use the connection valve unit 11 in the middle of the high pressure pipe as the pressure reducing valve unit 1, this plug 11
By removing a, and attaching the pressure gauge 6, the pressure reducing valves 8, 9 and the like as in the pressure reducing valve unit 1, a low pressure pipeline can be configured.

In the water supply valve unit 21, a short pipe clamp 3 with a handle 3a is fixed to the back of a small T-shaped pipe joint 22, and a water tap 25 is provided at the branched open end of the T-shaped pipe joint 22.
Are connected.

Further, a high-pressure hose 10 made of a flexible synthetic resin is used as a high-pressure pipe, and the male side of the union joint 5 is fixed to each end of each of the high-pressure hoses 10 in advance. A low-pressure hose 20 made of a flexible synthetic resin with a net, which is rich in durability, is used.

In the above configuration, the clamps 3 provided on each of the pressure reducing valve unit 1, the connection valve unit 11, and the water supply valve unit 21 are provided at appropriate places, for example, a pipe material 15 such as a scaffold.
Is detachably fitted to the outer periphery of the pipe, and can be fixed to the pipe member 15 by turning the handle 3a.

In the water supply system shown in FIG. 1, the pressure reducing valve unit 1 on the high pressure side is opened with the on-off valve 4 upward, and the pipe material 15
And the connection valve unit 11 is clamped to the pipe member 15 above it with the on-off valve 4 facing upward. A high pressure hose 10 connected to a high pressure pump P is connected to a lower opening end of the pressure reducing valve unit 1 by a union joint 5. Further, the opening end of the pressure reducing valve unit 1 on the opening / closing valve 4 side and the connection valve unit 1
1 between the lower open end and a high-pressure hose 10 of an appropriate length.
And are connected to each other by a union joint 5. further,
Another high-pressure hose 10 is connected to the opening end of the connection valve unit 11 on the opening / closing valve 4 side by a union joint 5, and the high-pressure pipe is extended upward in accordance with the floor height in the above-described procedure. The connection valve unit 11 or the pressure reducing valve unit 1 located at the uppermost end
Is closed with a stopper 11a so that high-pressure water does not flow out.

However, in this high-pressure pipe, the pressure reducing valve unit 1 may be provided on the way as the floor height is increased, and the connection valve unit 11 may be provided between the pressure reducing valve units 1 and 1.
The connection valve unit 11 may not be provided and the pressure reducing valve unit 1 alone may be used. In the above configuration, although not shown, an inclined inner end surface is formed on the female side of the union joint 5 (the open end side of the on-off valve 4), and the female side is formed on the male side (the high-pressure hose 10 side). An inclined outer end surface corresponding to the inner end surface is formed, and the outer end and inner end of both sides are tightened by unifying the female and male outer peripheral screws in one direction by bringing the ends together. Are fitted to each other to exhibit sealing performance. According to this union joint, it is not necessary to turn the hose side during connection, and the high-pressure hose 1
0 can be connected with only one wrench, high pressure hose 1
Since 0 has flexibility, even if the upper and lower joint positions are fixed, the high-pressure hose 10 can be bent between the joints and freely connected by a union joint. If a conventional steel pipe is used to make such a connection, an extra length of screwing is required at both ends of the steel pipe, so the fixed upper and lower joints are replaced later. Such a task is impossible at all.

On the other hand, a water supply valve unit 21 is clamped above the pressure reducing valve unit 1 with respect to the pipe member 15, and the branch side pressure reducing valve 8 of the pressure reducing valve unit 1 and the water supply valve unit 21 are connected by a low pressure hose 20. . The DC side pressure reducing valve 9 of the pressure reducing valve unit 1 can be connected to another low pressure hose 20 to form a separate low pressure pipe. Depending on whether the branch-side pressure reducing valve 8 and the DC-side pressure reducing valve 9 are different, for example, the branch-side pressure reducing valve 8 is used for a low-pressure pipe to an upper floor, and the DC-side pressure reducing valve 9 is used for a low-pressure pipe on the same floor. Can be used properly according to. Also, the required number of water supply valve units 21 are connected in accordance with the water supply point. However, the open end of the water supply valve unit 21 provided at the forefront is closed by a stopper 21a.

The low pressure hose 20 can be connected by inserting a hose around the open end of each joint and connecting the end of the hose to the band 20a without using a union joint as in the case of high pressure piping.
May be used.

In such a low-pressure pipe, high-pressure water supplied through a high-pressure hose 10 is reduced to an appropriate water pressure by adjusting the branch-side pressure reducing valve 8 or the DC-side pressure reducing valve 9, and the water pressure is reduced by a pressure gauge 6 And a suitable low-pressure water is supplied from a water supply valve unit 21 provided at several points on the low-pressure pipe.

[0020]

In the temporary water supply system for building construction according to the present invention described above, each valve unit can be freely mounted in place by a handle-rotating clamp to function not only as a clamping means for the entire water supply system but also as a high pressure system. Since both the pipe and the low-pressure pipe are made of a flexible hose, the clamp interval can be freely set and the pipe can be bent freely.

Therefore, even in a narrow place or a place where there are various obstacles, not only can the water supply system be easily assembled and installed without special skills, but also between the joints clamped up and down in advance. The hose can be freely installed and replaced later.

Further, according to the present invention, even at the time of removal after the completion of construction, the work of detaching the hose first or removing the clamp with the hose attached to the joint can be freely performed, so that the removal work is safe and easy. It can be done and reuse is sufficiently possible.

Further, since the hose is made of synthetic resin,
Incineration is possible in the case of disposal, and if it is made of a material that does not emit toxic gas at the time of incineration, problems in pollution control can be avoided.
