Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention supports pipes such as hot water supply / water supply pipes and drainage pipes, and also absorbs vibration of the pipes to prevent secondary noise from wall materials. The present invention relates to a swing support fitting.

[0002]

2. Description of the Related Art As is well known, when supplying drinking water or the like to the inside of a building or draining sewage or dirt to the outside of a building, use a pipe such as a hot water supply / water supply pipe or drain pipe. Has been done. However, the piping vibrates due to water hammer due to the fluid pressure of fluid such as drinking water, sewage, and dirt flowing in the piping, at that time, the vibration is propagated to the base plate via the supporting member of the piping, As a result, noise as a secondary sound is generated from the wall material formed of gypsum board or the like. This tends to be particularly amplified when a curved connecting member such as an offset pipe or an elbow is connected.

Therefore, as shown in FIG. 8, the pipe 7 arranged along the base plate 6 is supported by a saddle band type non-rubber support metal fitting 16. This rubber-less support fitting 16
Is a U-shaped bend of a metal plate, in which a pipe 7 arranged along the base plate 6 is covered with a rubber-free support metal fitting 16 and fixed with a screw 8 to the base plate 6.

Further, as shown in FIG. 9, when supporting the standing pipe 9 which is vertically arranged with respect to the base plate 6, the standing pipe 9 is supported by using a supporting metal fitting 17 of a standing pipe band type. I support you. The rubber-supporting metal fitting 17 is formed by attaching a hard synthetic rubber 18 having high hardness to the inner surface of an openable / closable annular metal fitting 10, and is fixed to the base plate 6 via a metal fitting 12. Mainly, it also has a function of supporting the standing pipe 9 arranged close to the base plate 6 to prevent the vibration thereof.

[0005]

However, according to the above-mentioned conventional technique, in the rubber-less support metal fitting 16,
Since no vibration damping member for absorbing the vibration of the pipe 7 is attached, the vibration of the pipe 7 is directly propagated to the base plate 6 without being damped, and the vibration damping effect cannot be expected. Further, in the rubber-equipped support fitting 17, since the synthetic rubber 18 of the rubber-equipped support fitting 17 is usually a hard material having a hardness of 55, vibration of the lightweight standing pipe 9 made of hard vinyl chloride or the like is prevented. The vibration cannot be sufficiently absorbed and the vibration is propagated to the base plate 6. The reason why the hardness of the synthetic rubber 18 is normally set to 55 is only to support the metal pipe and absorb the vibration of the pipe, and is made of synthetic resin such as hard vinyl chloride. It is impossible to support the lightweight pipes that have been prepared and absorb the vibrations of the pipes. Both of these have a problem that it is not possible to sufficiently prevent the generation of noise as a secondary generated sound from a wall material formed of gypsum board or the like. Further, this is remarkable when it is used for a lightweight pipe made of a synthetic resin such as hard vinyl chloride used in a low-rise house.

Further, the generated noise has a problem that it gives an occupant of a building an unpleasant feeling, which is also a cause of noise pollution.

The present invention solves the above-mentioned problems, does not matter whether the material of the pipe is metal or synthetic resin, absorbs the vibration of the pipe and prevents the generation of noise as a secondary sound. An object of the present invention is to provide a pipe vibration isolating support metal fitting.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has a U-shaped support metal fitting having a bendable extended vibration-proof portion on the inner surface thereof and having a hardness within the range of 2 to 12. A pipe anti-vibration support fitting was constructed by bonding and attaching an anti-vibration member.

An outer surface of the extended vibration isolator is coated with an adhesive layer, and a peelable release paper is adhered to the adhesive layer to form a pipe vibration isolator.

A pipe vibration isolating support metal fitting in which a flexible vibration isolating member having a hardness within a range of 2 to 12 is attached to the inner surface of an openable / closable annular metal fitting, and a mounting member is attached between a pair of clamping pieces of the annular support metal fitting. Configured.

A pipe vibration-damping support fitting was constructed by using the vibration-damping member as a plurality of fragment vibration-damping members.

The vibration isolating member is a pipe vibration isolating support fitting made of ethylene propylene rubber.

[0013]

With the above structure, when the pipes arranged along the base plate are supported for vibration isolation, the extended vibration isolation portion of the vibration isolation member attached to the inner surface of the U-shaped support metal fitting is angled inwardly. U-shaped support metal fittings on the base plate by bending the bottom surface of the pipe and the base plate so that the curved surface of the inner surface of the vibration-proof member and the upper half of the outer peripheral surface of the pipe come into contact with each other. To fix. In this case, even if the pipe is water hammered by the fluid pressure of the fluid flowing in the pipe and vibrates, the vibration has a hardness of 2 to 12
It will be absorbed by the flexible anti-vibration member within the range. Here, the hardness indicates the degree of hardness of an object, and 2 to 12 are the measured values of hardness by a hardness meter. In this case, when the vibration damping member is set to have a hardness higher than 12, the vibration damping member becomes hard according to the hardness and lacks elasticity, and lightweight pipe made of hard vinyl chloride or the like. It is not suitable for absorbing the vibration of. On the contrary, when the hardness of the anti-vibration member is set to be less than 2, the anti-vibration member becomes a considerably flexible member, and the outer peripheral surface of the pipe and the inner surface of the U-shaped support fitting come into contact while compressing the anti-vibration member. It will be inappropriate because it will be done. The hardness of the vibration damping member is set to 2 to 12 because the vibration of the pipe can be absorbed in the optimum state.

When a peelable release paper is attached to the outer surface of the extended vibration isolator, the release paper is removed in advance, and the U-shaped support metal fitting is attached to the base plate as described above. Try to fix it. By doing so, the extended anti-vibration portion is bonded to a fixed position of the base plate, and the extended anti-vibration portion can be prevented from slipping.

Further, in the case of supporting the pipe arranged vertically with respect to the base plate to prevent vibration, the openable and closable annular support fitting is opened, and the outer peripheral surface of the pipe is attached to the inner surface of the annular support fitting. The annular support fitting is closed by abutting against the inner surface of the attached annular vibration isolating member, and bolted to the member previously attached to the base plate. In this case, the pipe antivibration support metal fittings are arranged at a predetermined interval in the height direction of the pipes arranged between the floors.
It is better to install it in place. In the pipe thus mounted, even if the pipe is hit by water due to the fluid pressure of the fluid flowing in the pipe and vibrates, the vibration is absorbed by the flexible vibration isolating member having low hardness as described above.

Further, when the pipe is supported by a plurality of fragment vibration isolator members attached to the inner surface of the openable / closable annular support fitting, the fragment vibration isolator member may be a vibration isolator member having a slightly higher hardness.

[0017]

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the pipe vibration isolating support fitting 1 of the present invention has a U-shaped support fitting 2 and a hardness that is adhered to the inner surface of the U-shaped support fitting 2 with an adhesive tape or an adhesive. Is 1

It is composed of and.

The U-shaped support fitting 2 is provided at both ends with mounting pieces 4 bent at a right angle for fixing to a base plate or the like. Further, the inner diameter of the U-shaped support fitting 2 is formed to be slightly larger than the outer diameter of the pipe.

The vibration isolating member 3 is a member that serves to absorb the vibration of the pipe, and is made of a flexible synthetic rubber having a low hardness. The vibration-proof member 3 is adhered to the inner surface of the U-shaped support metal fitting 2 as described above, but is not bonded to the U-shaped support metal fitting 2 at one end thereof and is perpendicular to the inner direction. It has a bendable extended anti-vibration part 5. The extended anti-vibration section 5 has a release paper 5b adhered to the outer surface thereof via an adhesive layer 5a. The anti-vibration member 3 may not have the adhesive layer 5a and the release paper 5b. .

Piping antivibration support fitting 1 constructed in this way
2 is suitable for supporting the pipe 7 arranged along the base plate 6 as shown in FIGS. The mounting method is to bend the extended anti-vibration portion 5 from which the release paper 5b has been peeled off at a right angle inward so that the bottom surface 7a of the pipe 7 and the base plate 6 do not come into contact with each other. 6 and the base plate 6 are attached to the mounting piece 4 of the pipe vibration-damping support fitting 1 with screws 8 or the like. At this time, the outer peripheral surface of the upper half of the pipe 7 is the vibration isolator 3, and the bottom surface 7 a of the pipe 7 is sandwiched by the extended vibration isolator 5 of the vibration isolator 3. In addition, the extended anti-vibration portion 5 of the anti-vibration member 3 that contacts the base plate 6
Since the outer side surface of is adhered to the base plate 6 by the adhesive layer 5a, displacement of the adhered extended vibration isolator 5 can be prevented.

In this state, when the fluid flows in the pipe 7, even if the inner wall 7b of the pipe 7 is hammered by the fluid pressure of the fluid to cause the pipe 7 to vibrate, the vibration will cause the vibration of the pipe to be isolated. It is completely absorbed by the anti-vibration member 3 of the support fitting 1 which is highly absorbent. Thereby, the vibration of the pipe 7 is not propagated to the base plate 6, so that it is possible to prevent the generation of noise as a secondary generated sound of the wall material formed of a gypsum board or the like (not shown). Not only when the pipe 7 is made of metal, but also when the pipe 7 is made of lightweight hard vinyl chloride, the effect becomes even greater.
