The present invention relates to a prefabricated floor panel for preventing the noise between floors of a building, while the elastic member absorbs the floor support and the upper shock which is convenient to install and make a structure for preventing the inter-layer noise, and can effectively install the sound absorbing material. It relates to a building assembly floor panel that allows the sound absorbing material to absorb the impact sound.

As shown in FIG. 1, the floor structure of a conventional building is laid with a nonwoven fabric 2 on an upper surface of a floor slab 1, and a plurality of floor plates 3 are installed thereon. The bottom plate 3 is a coupling groove 4 is formed at one end, the coupling projection 5 is formed at the other end, the coupling groove 4 and the coupling protrusion 5 of the adjacent bottom plate (3). Are connected to each other and installed.

This conventional floor structure, however, all the floors constructed as described above, when the impact is applied from the top, the shock is delivered to the slab as it is delivered to the ceiling of the lower floor, so when children play on the upper floor, noise is generated in the lower floor, etc. There was this.

In order to solve this problem, the method of laminating an elastic member made of synthetic resin material on top of the slab and then placing concrete on it is applied to Korean Utility Model Registration No. 0297962, 2002. 09. 26. Anti-noise flooring) and Korean Patent Application No. 10-2003-0001186, 2003. 01. 08. application (composite interlayer noise prevention material).

However, the floor constructed by the above method was unable to stably place furniture, etc., or the shock-absorbing effect was not able to perform a proper noise-reducing effect.

In other words, if the elastic member is a low elastic elastic member having a weak elasticity, in the above-described structure in which no empty space is formed between the floor and the slab, the impact member is directly applied to the slab via the elastic body no matter where the impact is applied. Since it is transmitted, the effect of mitigating shock and noise is lowered.

However, the elastic member uses a highly elastic and high elasticity and the elastic member is easily recessed, so that the furniture cannot be stably positioned, and as the furniture is located, the overall flatness is lost.

In particular, there is a case where the center of gravity of the furniture is concentrated on one side, in this case there is a problem that the furniture can not be placed stably, such as inclined greatly in the direction in which the center of gravity is located.

On the other hand, in configuring the floor as described above, the elastic limit of the elastic member should be considered, but there is no technical configuration considering the elastic limit of the elastic member, if an excessive impact occurs in any part, the elastic member loses its original elastic force, Due to this there was also a problem that the floor is permanently recessed.

The impact sound and noise can be absorbed better in the groove 22 of the sound absorbing material, and the sound absorbing material can be used as a space in which the sound absorbing material can be elastically deformed, such as the elastic movement of the elastic member during the downward movement of the flooring material.

The sound absorbing material 20 absorbs a part of sound energy that strikes the surface of the material and reduces reflection sound. The sound absorbing material 20 is used in a place where a lot of noise is generated to make sound insulation and sound absorption.

The sound absorbing material is generally divided into a porous sound absorbing material and a plate-shaped sound absorbing material depending on the structure. Porous sound-absorbing material has many small bubbles or thin tube-shaped holes on the surface and inside, and the air in these holes vibrates by sound waves, and the sound energy is converted into thermal energy and absorbed by the friction generated. Sound absorption performance depends on the degree of porosity and the thickness of the material.

The plate-shaped sound absorbing material is a structure in which sound waves consume sound energy while vibrating the plate to obtain a sound absorbing effect. The sound absorbing performance of the bass portion is excellent, while the sound absorbing performance of the middle and high sound portions is poor. Materials used include veneers, gypsum boards, fiber boards, asbestos boards, and the like.

Therefore, in this invention, the porous sound absorption material which has some elasticity is used.
