Description

Large mat for vibration and noise prevention

The present invention relates to a large mat for preventing vibration and noise, and more particularly, to a mat that can reduce the transmission of vibration and noise between floors in apartments, multi-family houses, townhouses, officetels or buildings.

In general, Styrofoam is first installed on the ready-mixed concrete for insulation between floors of apartments, multi-family houses, tenement houses, officetels, or buildings, and foamed concrete is poured thereon. The floor work is completed by plastering mortar work.

As the floor of each floor is integrated with the wall by performing the floor construction as described above, the noise and vibration generated from the upper floor is transmitted to the lower floor through the floor and wall layers as it is. ), there is inconvenience due to noise and vibration.

In order to solve this inconvenience, a dust-proof pad is placed between the ready-mixed concrete and aerated concrete during the floor construction, and it is cited as Domestic Utility Model No. 192046 (Application No. 2000-6667, 'Anti-vibration pad between floors of a building'). devise) can suppress the transmission of noise and vibrations from the upper floors to the lower floors.

However, as the foam concrete and plastering mortar are disposed on the upper part of the interlayer dustproof pad of the building floor of the cited design, a phenomenon occurs that is bent by the load. In addition, there is a problem in that the anti-vibration pad is partially pressed by a high load and is damaged during long-term use. In addition, the conventional inter-floor anti-vibration pad is provided at the time of construction of a building, and there is a problem in that it is not easy to install and repair it, and it is difficult to replace it.

Therefore, there is a need for a large mat that is easy to install, has excellent durability, and can block noise and vibration.

An object of the present invention is to provide a large mat having excellent portability and durability while effectively preventing vibration and noise.

In order to achieve the above object, the present invention provides a buffer layer provided at the lower end of a large rectangular mat having two horizontal sides long in the horizontal direction and two vertical sides short in the vertical direction, and the buffer layer is provided above the buffer layer It consists of a surface layer and an epidermal film attached to the upper surface of the surface layer. And, the buffer layer is disposed on the upper surface of the buffer layer part and the buffer layer part for adhering to the member disposed above the arm layer part.

In addition, in the large mat, the buffer layer has one or more buffer layers according to the degree of vibration and noise, and when the height of one buffer layer in the buffer layer is h1 and the height of the surface layer is h2, the relationship between h1 and h2 is arranged so that h1>h2.
