Description

{Noise prevention flooring for building}

The present invention relates to a flooring for preventing building-to-building noise, and more particularly, to a flooring for preventing building-to-building noise, which is capable of absorbing vibration and impact by shortening the construction time and at least two or more sounding means, .

In recent multi - storey multi - family apartment complexes such as apartments, the upstairs noise or impact noise is becoming a big social problem due to the interstate noise transmitted to the lower floor.

Interlayer noise is mainly caused by footsteps generated when moving in the living space of an upper-floor resident, or when the door is opened or closed, when an object hits the bottom of a moving object or the floor, or when the child runs or rolls.

This kind of interstory noise is caused by the very good attainment of solid solid such as concrete structure. If it is neglected, it will cause serious social problems such as neighboring brawls as well as human accidents. Therefore, thorough measures are required.

Therefore, it is essential that the construction of the interlayer noise preventing means capable of preventing the noise or the shock vibration is almost indispensable at the time of flooring of each floor of the multi-storey apartment building.

As a conventional technique in which such a problem is partially solved, it is disclosed in Patent Registration No. 10-0741757, "Interlayer Structure of Floor Building ".

1, a panel 10 having a plurality of mesh holes 110 is connected to a buffer member 40 using a nut portion 13, And it is installed between the foundation bottom layer of the multi-storey building and the upper end mortar layer so that the interlayer noise isolation and the insulation effect can be obtained.

However, the conventional interlayer structure of the multi-layered building is too complicated in structure, resulting in a high manufacturing cost due to a high manufacturing cost. Only through the cushioning member 40 composed of the anti-vibration rubber constituting the leg, It is impossible to completely block the interlayer noise, and in particular, when the rubber is hardened, the interlayer noise is concentrated through the portion, and there is a limit to cause another secondary noise. Improvement is urgently required.

In addition, when the panel 10 is laid on the construction surface, there is no means for binding the plurality of panels 10 together, so that the panels 10 are separated from each other, making subsequent construction difficult and difficult to align horizontally .
