くない。Conventionally, metal pipes such as copper pipes and iron pipes have been commonly used as pipes for hot water supply, but the inventors of the present invention have developed a new method with the aim of making the pipes themselves lighter in weight, as well as considering the corrosion resistance and fatigue resistance characteristics of the pipes. proposed a synthetic resin pipe made of cross-linked polyethylene. However, due to the large coefficient of thermal expansion of the synthetic resin, the pipe expands and contracts greatly due to the temperature difference between when hot water is being supplied and when not. Sturdy tj that will not be moved due to expansion and contraction: It was found that it was necessary to consider a method of fixing the pipe. That is, as shown in FIG. 1, if the paper P is fixed at predetermined intervals in its longitudinal direction as f, f2, f8,..., then f2
If it is fixed for 61 minutes, the pipe during hot water supply will be in a uniform state of thermal expansion in each fixed section as shown by the broken line P' in Fig. 1, since the pipe P will move in 12 sections. , second
As shown in the figure, the thermal expansion is concentrated between f2.18 (possibly also between f11112), which is not preferable for pipe cloth installation.

の通′りである。Based on the above-mentioned new problems with synthetic resin pipes for hot water supply, the inventors of the present invention have conducted intensive studies on the method of fixing the pipes, and found that the method of fixing the pipes is similar to that used in ordinary pipe arrangement. However, the method of clamping the pipe with fixtures without deforming the pipe itself is insufficient, so it is necessary to fix and support the synthetic resin pipe for hot water supply by tightening it with fixtures to the extent that it is deformed from its original shape. By doing so,
For the first time, we have discovered that a method for fixing synthetic resin pipes for hot water supply can produce satisfactory results, and have completed the present application. However, the gist of the present application is as stated in the claims of the present application.

用できる。The pipe P used in the present invention may be made of synthetic resins of various families such as polyolefin, polyvinyl chloride, etc. In particular, polyolefin residue, polyethylene, and cross-linked polyethylene are suitable for quick stress relaxation and under repeated loads. Polyethylene pipes and cross-linked polyethylene pipes are particularly preferred because they have excellent long-term fatigue properties due to their large critical strain ht. Furthermore, water-crosslinkable polyethylene, for example, which has been modified to be water-crosslinkable with an organic silane such as vinyltrimethoxysilane and an organic peroxide such as dicumyl peroxide, can also be used as a pipe P with a foam material on the outside. A multilayer structure having a heat insulating layer and a protective layer can also be used.

Depending on the material and outer diameter of the pipe, the deformation meter can prevent displacement in the longitudinal direction of the fixed part of the pipe P even due to thermal expansion and contraction due to hot water supply or non-hot water supply to the pipe. It is preferable whether it is determined by the degree of tightening with a fixing tool for the general external shape of the pipe I (J) or whether the relationship between the displacement position Δd of the cut external shape satisfies the following equation.
