Description

FIELD STRUCTURE FOR SOUND INSULATION AND VIBRATION-PROOF USED IN A FLOOR OF AN APARTMENT BUILDING}

The present invention relates to an interlayer floor structure of a building which is installed on the floor of an assembly building, for example, an apartment, and blocks floor impact sound generated from the upper floor from being transmitted to the lower floor through the slab. The present invention relates to an interlayer floor structure having sound insulation and vibration damping functions, which are constructed between an interlayer concrete slab and an upper structure of a building, and used in an assembly building for providing sound insulation and vibration damping functions.

The floor impact sound is transmitted to the lower floor through floor slabs, ceilings or walls when an impact is applied due to human walking or falling objects on the upper floor of an assembly building such as an apartment or a villa.

These floor impact sounds are light impact sounds containing a lot of high frequency components, such as falling sounds of bowls, golf balls, and moving chairs and desks, and heavy impact sounds having low energy and high energy, such as walking of adults or jumping of young children. Separated by.

In general, the concrete slab that separates the lower and upper layers plays a primary role in sound insulation by blocking the air flow between the upper and lower layers.However, when a shock or vibration is applied to the dense concrete structure, the sound waves are not canceled. It has the property of being transmitted along the floor or wall by generation.

Therefore, in order to overcome this problem, in Western cultures where beds are mainly used, such as Europe or the United States, a method for minimizing the impact sound between upper and lower floors has been devised. The households had to pay special attention to noise generation for the downstairs living environment.

On the other hand, in the case of Korea, which uses a heating device such as ondol on the floor, the insulation structure that blocks heat between the upper and lower layers as well as the sound insulation structure between the upper and lower layers has been raised as one of the important problems in the construction.

1 is a cross-sectional perspective view showing a floor heating structure of a conventional multi-family house, the conventional floor heating system 10 used in the assembly building is formed on the concrete slab 12 for insulation to reduce the inter-layer impact sound Lightweight foamed concrete layer 16 is to be disposed on the lightweight foamed concrete layer 16 and the finishing mortar (19) on which the heating pipe 18 is embedded includes a finishing mortar layer (20).

According to the conventional floor heating system used in the assembly structure configured as described above, the heat released from the heating pipe 18 is passed through the finishing mortar 19 such as floor covering or flooring.

While the floor heating material is transferred to the floor finishing material (not shown), the floor impact sound generated by the collision with the floor finishing material is sufficiently reduced through the above-described conventional heating structure, and only a very small level of noise is transmitted to the lower floor. Delivered.

However, the conventional floor heating system 10 used in the aggregated structure of such a structure has a problem that the construction cost goes up and becomes complicated by constructing a separate flooring material in order to perform a vibration damping function or to smooth sound insulation or heat dissipation. .

The present invention has been made to solve the above problems, an object of the present invention, by using an interlayer flooring with sound insulation and vibration damping function between the concrete slab and the upper structure of the assembly building, the sound insulation prevention function between floors, It is an object of the present invention to provide a floor structure that can smooth the vibration damping function and heat dissipation and heat absorption.

In addition, another object of the present invention is to provide an interfloor flooring material that can facilitate the sound insulation prevention function, vibration damping function and heat dissipation and heat absorption between the floors in the assembly building.

Another object of the present invention is to provide a floor structure that effectively blocks the impact sound of weight that can not be blocked by low-density lightweight foam concrete.
