Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a soundproof and vibration-proof mounting structure for a water pipe, a hot water supply pipe, or a sewer pipe that is piped in a reinforced concrete building structure or the like.

[0002]

[Prior art]

 Conventionally, for example, a water pipe, a hot water supply pipe, or a sewer pipe to be installed in a reinforced concrete building structure or the like is attached by using a metal fitting having a substantially U-shape, and the sewer pipe or A pipe such as a water pipe was fixed to the building structure so as to be wrapped around the U-shaped portion.

However, since the fittings are generally made of metal, when water passes through the pipe, the passing sound and passing vibration are transmitted to the downstairs or the upstairs through the fittings and the reinforced concrete building structure. It had been transmitted to the room. That is, when the above-mentioned metal fitting (for example, U-shaped support saddle) is used, the concrete foundation material and the metal support saddle, or the metal support saddle and the pipe surface are in direct contact with each other. Therefore, the noise and vibration of running water in the pipes propagate to the surroundings.

Further, in the related art, since various pipes are firmly supported and attached by the mounting metal fittings, an external force generated during an earthquake or during work causes a very strong bending response to the pipes. In some cases, it was damaged. In addition, there was a problem that impact sound such as water hammer would be generated because it was firmly supported.

Further, as the diameter of the pipe is different, various metal support materials suitable for the diameter have been required.

[0006]

[Problems to be solved by the device]

 The present invention was devised to solve the above-mentioned conventional problems, and in particular, even if water passes through the inside of a pipe attached to a reinforced concrete building structure, its passing noise and passing vibration are not The purpose is to provide a soundproof and vibration-proof mounting structure for pipes that will not be transmitted to rooms.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned subject, the present invention is configured as follows. That is, a substantially strip-shaped base 1 made of an elastic member having flexibility, a rectangular notch 2 extending in the width direction of the base 1 and cut out, and continuous at one end side of the base 1. A band-shaped winding made of a flexible elastic member having a width substantially the same as that of the notch 2 and having a plurality of locking fins 3 at equal intervals in the longitudinal direction on both sides thereof. A pipe mounting member 5 having a portion 4 and, the outer periphery of the pipe 6 is wound by the winding portion 4, and the tip of the winding portion 4 is inserted into the notch 2 to form the pipe 6 and the mounting surface 7. The pipe 6 is attached to the structural member with the pipe mounting member 5 interposed therebetween.

[0008]

[Action]

 In the present invention, since the mounting member itself for mounting and supporting the pipe on the concrete foundation material is made of rubber and the pipe is wound by the mounting member, the concrete portion and the pipe are directly connected to each other. Since there is no contact point, it is possible to prevent the sound of passing water and the vibration of passing water in the pipe from propagating to the surroundings.

Since the mounting member is made of rubber, the mounting member itself expands and contracts against an external force generated during an earthquake or during work, so that the stress is absorbed, and the pipe is borne. There is no danger of damage as it is not applied. Furthermore, it is possible to flexibly absorb the impact sound of a so-called water hammer.

With this mounting member, even if the diameter of the pipe changes, one type of mounting member can suffice.

【Example】

 The present invention will be described below based on the preferred embodiments shown in the drawings. FIG. 1 is a schematic view showing a pipe mounting member 5 according to the present invention, and reference numeral 1 denotes a base portion thereof. Here, the base 1 is formed of a flexible elastic member in a substantially band shape, and a rectangular notch 2 extending in the width direction and cut out is provided at a predetermined position of the base 1. Has been.

Further, a winding portion 4 which is continuous with the base portion 1 and has a width substantially the same as that of the notch 2 is provided on one end side of the base portion 1. The winding portion 4 is also formed of an elastic member having flexibility in the same manner as the base portion 1. Here, as the elastic member having flexibility, the one in which cloth is inserted into the rubber as the mountain layer for reinforcement is used, but it may be formed of only the rubber, soft plastic, laser, etc. Can also be used.

Further, a plurality of locking fins 3 ... Are provided on both sides in the width direction of the winding member 4 so as to extend in the longitudinal direction and be equally spaced. Here, the use state of the present invention will be described. First, a pipe mounting member 5 is wound around a pipe 6 such as a water supply pipe or a hot water supply pipe as shown in FIG. That is, the tip end of the strip-shaped winding part 4 is inserted into the notch 2 provided in the base part 1 and further brought into close contact with the outer circumference of the tube 6 as shown in FIG.

Here, the thickness of the tube 6 is not limited to any particular value, and the length of the winding portion of the winding portion 4 is simply changed depending on the thickness of the tube 6 and is provided on both sides of the winding portion 4. In addition, the locking position of the plurality of locking fins 3 ... with respect to the notch 2 changes. Further, as can be understood from FIGS. 1 and 2, after the winding portion 4 is wound, the nail 8 is penetrated into the mounting holes 9 provided on the base portion 1 side and the strip-shaped winding portion 4 side of the pipe mounting member 5. , Is fixed to the mounting surface 7.

Note that FIG. 3 shows another mounting state. When the mounting surface 7 is erected in a vertical direction such as a wall, the nail 8 is mounted at one mounting point. You can also

[Effect of device]

 The present invention has the above configuration. With the soundproof and seismic-proof mounting structure of the pipe according to the present invention, it is possible to eliminate the noise caused by the passing sound and passing vibration of water generated in the pipe. Furthermore, since it is flexibly attached, the pipe can be protected from bending stress generated during an earthquake and external force generated during work.

Further, the pipe can be protected from the stress generated by the rapid pressure change inside the pipe. Furthermore, one kind of mounting member can be used for various diameters of the pipe. In addition, for example, even in the case of piping work on a ceiling or the like, the work can be completed with significantly higher work efficiency as compared with the conventional mounting hardware.
