Description

Comprehensive construction method for reducing noise between floors of apartment houses {COMPREHENSIVE CONSTRUCTION METHOD FOR REDUCING NOISE BETWEEN FLOORS IN APARTMENT HOUSES}

The present invention relates to a comprehensive construction method for reducing noise between floors of an apartment house. More specifically, the independence and comfort of residential space are secured by reducing the noise of various frequencies transmitted through the floor of the upper floor and the ceiling of the lower floor in an apartment building and the noise of various frequencies transmitted through the load-bearing wall shared by the upper and lower floors. It is about a comprehensive construction method for reducing inter-floor noise in apartment houses that can be done.

An apartment, multi-household villa, etc., where multiple people share a building and live in it, is collectively referred to as an apartment building. The floor of the upper floor and the ceiling of the lower floor are made of a single slab, and the load-bearing walls are also shared by the upper and lower floors.

However, due to the unavoidable structure of such apartment houses, a problem of noise between floors occurs, and as the number of people living in apartment houses increases, this problem is developing into a more serious social problem.

Most of the noise between floors is generated on the upper floor and propagates to the lower floor. It is common for residents to move, footsteps, doors opening and closing, electronic products operating, and children running or rolling. It is generated as the sound generated by the lamp is transmitted to the residential space on the lower floor through the floor slab and wall of the upper floor constructed of reinforced concrete.

Various technologies are being developed to reduce such inter-floor noise. Korean Utility Model Registration No. 20-0324664 relates to an inter-floor floor structure using a shock-absorbing sound-insulating sheet, which reduces the impact generated from the finishing mortar layer and the inter-floor structure. Aluminum silver foil 110, which is constructed on top of the concrete slab layer 100, and aluminum silver foil 110, which are constructed on top of the Sound absorbing material 120 of synthetic resin material, shock absorbing sound insulation sheet 130 of synthetic resin material installed on top of sound absorbing material 120, Styrofoam 140 installed on top of shock absorbing sound insulation sheet 130, Styrofoam 140 An interlayer floor composed of a color zinc steel plate 150 installed on top, a synthetic resin sound insulation sheet 160 installed on top of the color zinc steel sheet 150, and a finishing mortar layer 170 installed on top of the sound insulation sheet 160. suggest a structure.

However, in the sound insulation sheet 130 for shock absorption of Korean Utility Model Registration No. 20-0324664, a plurality of space-forming protrusions 132 are formed at regular intervals, and the space-forming protrusions 132 form a gap between the sound-absorbing material 120 and the sound-absorbing material 120. It is characterized in that the air layer 134 is formed at regular intervals. If the air layer 134 is provided in this way, noise of a specific frequency inside the air layer causes resonance to cause the opposite effect to noise or sound absorption. Therefore, there is a problem that the sound insulation effect is not sufficient. In addition, it is difficult to absorb noise of various frequencies generated from various noise sources other than impact, and it is impossible to insulate noise propagating along a shared wall (bearing wall).

Therefore, there is a need for a technology that can secure the independence and comfort of living space by reducing the noise of various frequencies propagated along slabs and shared walls.
