The present invention relates to an interlayer noise preventing material and a sidewall noise preventing material and an interlayer floor structure of a multi-family house using the same. Specifically, an interlayer noise preventing material and a sidewall noise preventing material which block noise and vibration by securing an air layer, and The floor structure of the multi-unit house used.

In general, a common construction method of two-story or more buildings such as apartments or multi-unit houses is to construct concrete slabs according to the number of floors of the building to complete the basic construction, and then arrange heating pipes on the concrete slabs at regular intervals. In the construction of gravel and cement mortar to a predetermined thickness.

As the slab that divides the floors and floors of multi-storey multi-storey buildings such as apartments and high-rise buildings is constructed of concrete only, the noise and shock generated inside the relevant floor of the building are directly lowered through the interlayer slabs. Is passed to.

In general, the impact sound applied to the building structure of apartment houses such as apartments and villas is transmitted to all directions by solid walking sound generated by people walking, opening and closing doors, moving objects, starting or stopping equipment, etc. This causes the surface of the building structure to vibrate, as well as being converted to air transmission sound, which is perceived as noise when it is heard by people around it.

For example, an impact such as a drop of an object is applied to the floor or a movement of a chair generates a solid transmission sound, and the solid transmission sound is transmitted to the lower floor through the floor slab.

Nowadays, the problem of floor noise has emerged seriously in apartment houses, and the government has announced that it will impose penalties for neighboring noise-induced acts by applying the neighboring crimes of the misdemeanor punishment law, and even struggling between neighbors with floor noise. As a result, regulations on housing construction standards have been strengthened and revised.

The regulations stipulate that the floor impact sound between floors should be less than 58 decibels (dB) and the weight impact sound should be less than 50 decibels (dB) or standard floor structure as determined and announced by the Minister of Construction and Transportation.

As such, conventional interlayer floor structures are proposed for minimizing and minimizing severely generated interlayer noise, which is based on a concrete slab 1, as shown in FIG. Lightweight foam concrete layer (2) is formed on the upper part, and heating pipe (3) and finishing mortar layer (4) are formed on the upper part, and the floor decorative layer (5) made of decorative materials such as monolium, solid wood, and tiles thereon (5). It is composed of

However, the interlayer floor structure above, but the lightweight foam concrete layer formed on the top of the concrete slab is responsible for attenuating the noise, the situation is not properly absorb or block the noise, such as light impact sound and heavy impact sound. Therefore, when the building is constructed with such a conventional floor structure, the noise and vibration caused by the impact applied to the floor, for example, by the children running around on the upper floor, are immediately transmitted to the lower floor. As a result, the comfort of the building is greatly reduced. Will be.

Due to this, in order to more effectively block noise or impact, a construction method for forming an interlayer noise preventing material between the concrete slab and lightweight foamed concrete has been developed.

Such an interlayer noise prevention material is usually made of a resin material, and provides a floating structure for forming an air layer by forming protrusions on the bottom surface, wherein the hardness of the interlayer noise prevention material and the protrusions is 40 or less or 80 or more.

However, since the hardness of the interlayer noise preventing material and the projection is about 20 to 40, it is very flexible and excellent in elasticity. When pressed under the weight of lightweight concrete and mortar (170kg per 1m × 1m), interlayer noise prevention material and projections are attached to the slab surface, and no air layer is formed, and the function to block vibration and noise is lost. The reality is that it is very slight.

In addition, the air layer may be formed when the hardness of the interlayer noise preventing material and the protrusion is 80 or more, but the noise is secured by the air layer because the protrusion is attached to the slab surface and the noise is transmitted through the strong interlayer noise preventing material and the protrusion. It will cancel the blocking effect.

In addition, there are many kinds of floor noise prevention materials that are currently used, but there are many types, but all of them are laid on the concrete slab surface of the apartment house, so the noise blocking effect is not great. For example, the existing interlayer noise prevention material is mainly in the form of laying styrofoam insulation or other synthetic resin foam sheet on the slab surface of the multi-family house and placing lightweight foam concrete and mortar on it, there is a disadvantage that the noise is not blocked and transmitted.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an interlayer noise prevention material and a side wall noise prevention material and an interlayer floor structure of a multi-family house using them to secure noise and vibration by securing an air layer.

In addition, the interlayer noise prevention material is laminated on the floor slab surface and immediately forms the heating piping and finishing mortar layer to reduce the concrete thickness of the floor, thereby reducing the construction time and the construction cost. Another object is to provide a noise preventing material and an interfloor floor structure of a multi-family house using them.

Characteristic of the interlayer noise prevention material according to the present invention for achieving the above object is a first board formed of a synthetic resin material in the form of a square plate, having a hardness of 70 or more; A plurality of supports formed of synthetic resin or rubber and attached to the bottom of the board; And a first absorption plate made of a rubber material and attached to the bottom of the support.

Characteristic of the side wall noise prevention material according to the present invention for achieving the above object, the second board is formed in a rectangular plate shape of a synthetic resin material, having a hardness of 70 or more; It is made of a rubber material, characterized in that it comprises a second absorption plate attached to the bottom of the second board.
