Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel vibration-proof and sound-insulating material, and more specifically, it is an anti-vibration material that is made by integrating a hard material plate-like body and a soft material protrusion, and is inexpensive and can be installed with one touch. This relates to sound insulation materials.

In recent years, active environmental improvements have been made, especially improvements to the living environment, but the most lagging behind these efforts are the problems of vibration and sound insulation. Although the density of houses in Japan is extremely high, the noise level of the houses is significantly lower than that of houses in Europe and America. Additionally, in apartment complexes, in addition to poor sound insulation, sound transmission through the floors is a major problem, and vibrations from people living on the upper floors are transmitted through the ceiling to the lower floors, making life uncomfortable. . On the other hand, damage to houses, such as shifting of roofs and cracks in walls, due to vibrations caused by aircraft noise, highways, railways, etc., has become a serious problem. These noises and vibrations cause not only property damage but also psychological damage, hindering cultural life and labor reproduction, and it can be said that solving these problems is an urgent national task.

Regarding sound transmission through floors, dry sound insulation flooring methods using high-density glass wool as a core and flooring materials based on lead foil have been proposed, and -!
Compressed glass wool and ceramic string rigid sound absorbing materials have been proposed, but both are expensive and have no practical construction features.
(There is one.

In view of the actual situation, the present inventor has arrived at the present invention as a result of intensive research into vibration and sound insulating stones that are inexpensive and easy to construct.

That is, the first aspect of the present invention is a vibration/sound insulating material formed by integrating a plate-like body made of a hard material and a plurality of protrusions made of a soft material, and the second aspect of the present invention is a plate-like body made of a hard material. and a plurality of protrusions made of a soft material are laminated and integrated with a synthetic resin film, and the third aspect of the present invention is a heat insulation plate having a plate-like body made of a hard material and a plurality of perforations. The vibration and sound insulating material is made by inserting and integrating a protrusion made of soft material (Schiff: Js) into the perforation so that the tip thereof protrudes.

The hard material used in the present invention includes hinyl chloride m
Hard plastics such as resin, ABS resin, phenol resin, urea resin, wood board, plywood, metal plate, etc. are suitable.
Any material can be used as long as it has a certain level of rigidity and strength.

The soft materials used in the present invention include natural comb, S
Vibration of synthetic combs such as B R, N B R, butyl rubber, fluorocarbon rubber, ethylene-propylene rubber, rubbers such as polyvinyl acetate, ethylene-vinyl acetate copolymer, polyurethane foam, polyethylene foam, nidistomer, plastic foam, etc. Any elastic material with absorbent properties may be used.

The vibration/sound insulating material of the present invention has a structure in which a plate-like body made of a hard material and a plurality of protrusions made of a soft material are integrated. The vibration/sound insulating material of the present invention is installed under the floor, between the floor and the ceiling, between the exterior material and interior material of the wall, etc. Therefore, the size is not particularly limited, and any size that provides good construction efficiency and is easy to handle may be selected. The thickness of the plate-shaped body is not particularly limited, but is approximately 0.1π as long as it holds the protrusion, receives vibrations from the floor or wall, and transmits this to the protrusion.
It may be selected within a range of about m to 20n. On the other hand, the protrusions function to inherit and absorb vibrations from the plate-like body and prevent them from being transmitted to the ceiling or walls. Therefore, although it depends on the magnitude of noise and vibration, the size of the protrusion is not particularly limited.

However, if the contact area with the plate-shaped body is too large, the vibration absorption properties will be reduced, and the ventilation layer will be reduced accordingly, reducing the vibration-proofing, soundproofing, and sound-insulating effects of the ventilation layer. Therefore, it is suitable that the total area of the protrusions is 70% or less of the plate-like body, preferably in the range of 50% to 20%. There is no particular limit to the height of the protrusions, but if the height is too large, it will be necessary to enlarge the space between the floor and the ceiling where the protrusions are to be inserted, and between the exterior and interior materials of the wall, which will prevent effective use of space. Contrary. Therefore, about 0.5 mm to 30 πm, preferably about 1 to 5
It should be decided within the range of fighting. Examples of the protrusions include wart-like protrusions, circular, elliptical, rectangular, and polygonal columnar protrusions, band-like protrusions, sheets having these protrusions, and porous sheets 1 to 1, mesh-like sheets, and the like. The protrusions and the plate-shaped body are integrated with each other by adhesion, bathing, mechanical joining using screws, or a combination thereof.

The above integration can also be achieved by laminating synthetic resin films. As the synthetic resin film, polyethylene, polypropylene, polyester, polyamide, etc. are preferably used.

In addition to integrating the film, the coating has the effect of protecting protrusions, and is particularly effective in protecting protrusions made of rubber that is weak in water resistance, greatly extending durability. .

It is also possible to further integrate the plate-like body and the protrusion through a heat insulating plate. That is, a plate-like body made of a hard material and a heat insulating plate having a plurality of perforations are integrated by bonding, welding, screwing, etc., and protrusions made of a soft material are inserted into the perforations. As the heat insulating plate, Bo-11 styrene foam or the like is suitable. The protrusion is inserted so that its tip protrudes from the perforation of the heat insulating plate. The perforation may be a concave hole or a through hole. In addition, the protrusions can be easily inserted and bonded.
It may be welded. In this case, since the structure uses a heat insulating plate, the sound insulation and vibration proof effects are further enhanced, and a high-performance heat insulation effect is added.

The vibration-proof and sound-insulating material of the present invention can be inserted between the floor and the ceiling, or between the wall exterior material and the interior interior, but if it needs to be nailed, etc., it should be installed at the same height as the protruding object. It is best to attach a wooden board, plywood, etc.
