Description

SHOCK ABSOBING ASSEMBLY HAVING A PLURALITY OF LAYERS FOR BOTTOM OF BUIELDING}

The present invention relates to a shock absorber assembly disposed on a building floor to mitigate the impact of an impact applied to the floor of an upper floor to an adjacent lower floor.

In general, houses that are built on two or more floors, particularly townhouses or apartments, will transmit noise or vibration generated from the upper floors of two adjacent floors to the lower floors. These noises or vibrations are caused by human activity on the upper floors or by falling objects.

Noise due to the impact on the floor can be divided into light impact sound due to relatively light and hard impact and heavy impact sound due to relatively heavy and soft impact.

The noise between the two adjacent floors, that is, the noises that are not blocked at the floor, worsens the living environment of the lower floor.

However, the above method causes a problem that the overall height of the building or the height of each floor is to be lowered, there is a need to solve the problems such as noise by improving the cushioning material included in the floor.

One object of the present invention is to provide a shock absorbing assembly for a building floor different from the prior art.

Another object of the present invention is to provide a shock absorber assembly for effectively dispersing the noise, vibration caused by the impact on the building floor.

It is yet another object of the present invention to provide a shock absorber assembly for effectively blocking or mitigating noise and the like while minimizing an increase in floor thickness.

According to an embodiment of the present invention for realizing the above object, a multi-layered buffer structure assembly having at least one protrusion formed on a first surface thereof and formed of a foamed resin, and A second substrate laminated on a second surface and formed of a foamed resin; a first member disposed between the second surface of the first substrate and the first surface of the second substrate; and a second surface of the second substrate. A second member laminated, wherein at least the first member of the first and second members comprises a rubber body, each of the first and second members having a thickness less than both of the first and second substrates; It is formed to have.

According to an aspect of the present invention, the first and second substrates are each formed of expanded polystyrene. The first and second surfaces of the first substrate and the first and second surfaces of the second substrate may be opposite surfaces of the first substrate or the second substrate, respectively.

According to another aspect of the present invention, the at least one protrusion includes a plurality of protrusions formed in a grid form.

According to another aspect of the present invention, the rubber body comprises at least one of a carbonized rubber body, a rubber sheet in the form of a chip. The chipped carbonized rubber body includes tire chips formed by crushing tires.

The shock absorbing material assembly of the multi-layer structure for a building floor according to the present invention configured as described above allows the shock applied to the floor to be effectively absorbed by the rubber body or non-woven fabric disposed between the multi-layered substrates and on or on one side thereof. As a result, noise and vibration due to the impact applied from the upper layer are alleviated and transmitted to the lower layer.

In addition, by using tire chips obtained by crushing tires as elastic bodies, it is possible to recycle waste tires. This not only lowers the manufacturing cost of the shock absorber assembly, but also has an economical meaning of using waste resources once more.

Furthermore, the tire chip or the rubber body is less occupied in the overall thickness of the floor, thereby preventing the thickness of the floor from becoming thicker than specified.

Hereinafter, with reference to the accompanying drawings for the building floor buffer assembly according to a preferred embodiment of the present invention will be described in detail.
