Description

{A, IMPACT SOUND INSULATING SHEET OF AN APARTMENT HOUSE USING THE SAMESEET}

The present invention relates to a sheet for reducing interlayer noise in a dwelling house, and more particularly, to an interlayer noise reduction sheet improved in noise suppression and buffering action by including a foam between synthetic resin layers to be adhered.

In addition, the interlayer noise reduction sheet of the present invention is interposed between the concrete floor and the mortar layer of the apartment house, and is extended to the predetermined height of the wall from the concrete floor to improve the noise reduction effect Method.

Domestic urban residential environment has been developed as a dense residential space mainly as apartment house or multi - family house due to efficient utilization of narrow land and increase of land price of residential land.

Although the residential space should be a space where people can rest and relax freely at any time, these multi-family houses are arranged vertically and horizontally so that the noise generated from the upstairs and the next house is transmitted to harm the comfortable living environment Often it causes disputes with neighbors. However, it is not possible to reduce the noise generation in life, and it is desired to improve the building structure to reduce the interlayer noise.

In order to solve the interlayer noise problem, efforts have been made to improve the construction method using the interlayer noise reduction material or the noise reduction material.

A noise preventing floor structure is disclosed.

However, in the above-mentioned conventional technologies, it is possible to reduce the impact sound applied to the floor surface directly to the lower layer by installing the heat insulating material or the noise reduction material on the concrete floor surface. However, There is a problem that it is impossible to reduce or prevent an impact sound or noise transmitted to a lower layer through a wall body integrally formed with the floor surface.

Korean Patent Registration No. 10-1267523, which was registered on May 20, 2013 as an improvement measure, is provided with a structure for preventing the noise of the upper layer from being transmitted to the lower layer through the wall of the residential building, as schematically shown in FIG. An interlayer noise protection system comprising: a sound barrier (16) having a hard inner wall (23) and an outer wall (26) between a floor material (14) applied to the top surface of a slab (12) and a building wall (10); A noise separator (65) installed at the floor member so as to be spaced apart from each other to reduce interlayer noise; And a heat insulating material (70) for blocking heat transfer between the upper surface of the slab and the bottom material; Wherein the heat insulating material 70 has a polypropylene (PP) film adhered to an aluminum thin plate, so that the lower surface of the aluminum polypropylene film 71 having heat insulating property, moisture proof property, And a carbon rubber pad 75 containing carbon having antibacterial and deodorizing properties on the upper surface of the film 74. The noise separator 65 forms an internal space between the hard inner wall and the outer wall, The soundproofing device according to claim 1, wherein the inner space is filled with any one of a sound insulation material and air or vacuum to form an inner space between the hard inner wall and the outer wall, And the outer end of the bent plate has a downwardly bent extension portion so that the extension portion 50 and the vertical inner wall 43 The interlayer noise prevention system, characterized in that between the surface and the inner wall of the upper bent plate of the floor to form a space portion (a) has been proposed which is located.

However, since the above-mentioned conventional interlayer noise preventing system of the prior art is complicated in structure and difficult to install, it is not possible to place heavy furniture or the like immediately on the heat insulating material, so a mortar must be separately installed thereon. In this case, There is a problem in that the amount of overflow increases.
