Description

 Floor floor structure of apartment house {FLOORS STRUCTURE OF AN APARTMENT HOUSE USING IMPACT SOUND INSULATING MATERIAL}

The present invention relates to an interfloor floor structure of a multi-family house, and more particularly, to an inter-floor floor structure of a multi-unit house by installing a synthetic resin layer through which a plurality of regular hexagonal holes are perforated in the inter-floor floor and sidewalls of the multi-unit house. It is about.

According to the present invention, by constructing a plurality of layers of synthetic resin layers formed with a plurality of regular hexagonal holes stacked, it can effectively block the noise and vibration transmitted through the floor and side, reduce the concrete thickness of the floor, having a synthetic resin layer Due to the insulation effect, it is excellent in heat retention and can prevent heat loss.

As disclosed in Korean Patent Registration No. 750890, in general, a conventional construction method of a two-story or more building such as an apartment or a multi-family house is completed by constructing a concrete slab according to the number of floors of a building, and then completing concrete In the state where heating pipes are arranged on the slab at regular intervals, gravel and cement mortar are constructed 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 the noise of floor noise by applying the neighboring sin of the misdemeanor punishment law, and even strife between neighbors due to noise between floors. in

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 the 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 protrusion is about 20 to 40, it is very flexible and excellent in elasticity. In fact, the existing layer of noise preventing material is laid on the slab surface of the apartment house, and light weight foam concrete and finishing mortar are placed on it. When pressed against the weight of lightweight concrete and mortar (170kg per 1m ㅧ 1m), interlayer noise prevention material and projections are attached to the slab surface and air layer is not formed at all, 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, and there are many kinds, but all of them are laid close to the concrete slab surface of the apartment house, so the noise blocking effect is not large. 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, an object of the present invention is to install a synthetic resin layer through which a plurality of regular hexagonal holes through the floor and side walls of the multi-family housing to prevent the noise between floors To provide an interlayer floor structure.

The interlayer floor structure of the multi-family house of the present invention includes a synthetic resin layer 51 disposed on the upper surface of the concrete slab 1, a first moisture proof film 52 disposed on the upper surface of the synthetic resin layer 51, and the first layer.

A plurality of regular hexagon holes are disposed on the first cover 54, the second moisture proof film 55 disposed on the upper surface of the first cover 54, and the upper surface of the second moisture proof film 55.
