JP2001329645A - Vibration-proof member, and strut structure using the same - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a vibration-proof member which can cope with not only vertical vibrations but also horizontal vibrations, is stable in strength in terms of the structure of the vibration-proof member, facilitates its installation, and is excellent in vibration absorbency and soundproofing performance, and to provide a strut structure using the vibration-proof member. SOLUTION: The strut uses a first vibration-proof member and a second vibration-proof member. The first vibration-proof member is obtained by subjecting a connecting surface of a rubber isolator to vulcanization to bond the rubber isolator to a support iron plate, and embedding a stud in the rubber isolator, to thereby enhance the adhesion between the rubber isolator and a support steel product. The second vibration-proof member is obtained by shaping the support steel product such that a rise portion is formed at one end of a flat substrate so as to have an L-shaped cross section, and arranging the rubber isolator on internal surfaces of the flat substrate and the rise portion which shape the ell in cross section. By virtue of the use of these vibration-proof members, the strut can be made excellent in vibration isolation efficiency.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-vibration member which is preferably used in a structure of a bundled pillar which is arranged on a foundation of various buildings, and which is supported on a boulder by a pillar member capable of vertically moving a joist. About.

[0002]

2. Description of the Related Art Conventionally, as a bundling pillar constituting a foundation of various buildings, as shown in FIG. And then nail this bundle of timber to the joist 3 or the same figure (b)
As shown in (1), a method of supporting the joist 3 via a bundle member 2 made of iron or plastics, which can be moved up and down by a screw, has been adopted.

In recent years, in order to cope with noises and vibrations in or around an urban area, as shown in FIG. 5, an anti-vibration rubber 4 is provided between a bundle member 2 made of plastics and a joist 3. You can see the structure of the arrangement. However, the plastics and the vibration-isolating rubber cannot be formed as an integrated structure because the molding temperatures are different from each other, and the plastics and the anti-vibration rubber are also provided on the top of the screw rod 5 of the upper bundle member of the bundle member 2. A vibration-proof rubber receiving member 51 of the vibration-proof rubber 4 is provided, and after the vibration-proof rubber 4 is disposed therein, the vibration-proof rubber receiving member 51 and the joist 3 are nailed.

[0004] As a structure of a vibration isolating member, there is also a structure in which a vibration isolating rubber is sandwiched between supporting iron plates from above and below.
The bonding force between the vibration isolating rubber and the supporting iron plate is weak, so that even when applied to support the bundled column member 2 as shown in FIG. 5, the vibration isolating rubber is easily peeled off from the supporting iron plate and is unstable.

[0005]

The problem to be solved by the present invention is that it can cope not only with vertical vibrations but also with horizontal vibrations, and as a structure of a vibration-proof material, its strength is stable. Another object of the present invention is to provide a vibration-proof member having excellent vibration absorption and sound-proof properties and a structure of a bundle using the same.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a vibration isolating member comprising a supporting iron plate and a vibration isolating rubber bonded to a surface of the supporting iron plate. This is due to the vulcanization of the rubber bonding surface. By this vulcanization treatment, the adhesiveness between the vibration isolating rubber and the supporting steel material is enhanced.

Further, in the vulcanization treatment, the stud having an integral structure with the supporting steel material is inserted into the vibration isolating rubber and arranged, so that the fixing of the vibration isolating rubber to the supporting steel material can be ensured by the anchor effect of the stud. .

Further, the supporting steel material has an L-shaped cross-sectional shape having a rising portion at one edge of the flat substrate, and a flat substrate having the L-shaped cross-sectional shape and a vibration isolating rubber disposed on the inner surface of the rising portion. By doing so, the side surfaces of the building material to be vibration-proofed on the L-shaped inner vibration-proof rubber can also be vibration-proofed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to an embodiment 10 shown in FIG. 1 in which the vibration damping member of the present invention is applied to a bundle.

In the bundle structure 10 according to the present invention shown in FIG. 1, the joist 3 is supported by the bundle member 2 placed on the slab 1. Reference numeral 20 denotes a first vibration damping member arranged between the pillar member 2 and the slab 1. FIG. 2 shows a cross-sectional structure of the first vibration isolation member 20. As shown in FIG. 2, both surfaces of the plate-shaped anti-vibration rubber 4 are sandwiched between the supporting iron plates 6, and are firmly bonded to the supporting iron plates 6 by vulcanization. Further, a stud 61 having an integral structure with the supporting iron plate is inserted into the anti-vibration rubber 4, and the bonding between the anti-vibration rubber 4 and the supporting iron plate 6 is strengthened by the anchor effect of the stud 61. Therefore, even if the first vibration-proofing member 20 is placed between the pillar member 2 and the slab 1, the vibration-proof rubber 4 and the supporting iron plate 6 of the vibration-proofing member 10 are peeled off by the lateral vibration. There is no deviation, and the propagation of vibration from the slab 1 to the spar member 2 is reduced. In the figure, a screw rod 5 of a bundle member of the bundle member 2 is integrally attached to an upper surface of the vibration isolating member 10.

Returning to FIG. 1, reference numeral 30 denotes a second vibration isolation member disposed between the screw rod 5 and the joist 3 of the bundle member of the bundle member 2. FIG. 3 shows the second vibration isolator 3
0 is clearly shown. As shown in FIG. 3, the supporting iron plate 6 has a rising portion 63 formed at one edge of the flat substrate 62 to have an L-shaped cross section.
The anti-vibration rubber 4 is provided on the inner surface of the flat substrate 62 and the rising portion 63 having the L-shaped cross section. The screw rod 5 of the bundle member of the bundle member 2 is integrally attached to the lower surface of the flat substrate 62 of the support iron plate 6 of the second vibration isolation member 30. Also, 64 is
9 shows an insertion hole for a nail material for attaching the vibration isolator to the joist.

Then, as shown in FIG. 1, the first vibration isolating member 20 is arranged between the pillar member 2 and the slab 1, and the first vibration isolation member 20 is connected to the screw rod 5 of the pillar member of the bundle member 2. The joist 3 is supported on the flat substrate 62 of the L-shaped supporting iron plate 6 of the second vibration isolating member 30 disposed between the joist 3 and the screw rods of the bundle members. 5 is inserted into the main body 7 of the bundle member 2 of the bundle member 2 to form a bundle.

[0013]

According to the present invention, the following effects can be obtained.

1. Since the anti-vibration member of the present invention has a structure in which the anti-vibration rubber and the supporting steel material are firmly integrated, even when applied to a wooden building, it does not become an unstable factor at the time of building.

2. It can cope with any type of vibration exerted on a building. By applying the present invention to a bundle, it is possible to obtain a building in which the vibration is attenuated and the soundproofing effect is enhanced.
