The present invention relates to a floor structure and a construction method for reducing interlayer noise transmitted to a floor and a wall of a multi-storey house. More particularly, the present invention relates to a floor structure and a construction method, To a floor structure and a construction method for reducing interlayer noise.

Generally, in the case of apartment houses, noise from the upper and lower floors causes many inconveniences, hinders comfortable housing, and even causes disputes between neighbors. Therefore, much efforts are being made to prevent interlayer noise in the floor structure of buildings.

Background Art [0002] An interlayer noise isolation structure of a building is described below with reference to the accompanying drawings.

1 is a cross-sectional view illustrating a bottom structure for reducing noise transmitted between a floor and a wall of a multi-unit house according to a related art.

Referring to FIG. 1, a bottom structure 10 for reducing interlayer noise transmitted to a floor and a wall of a multi-unit house according to the related art includes a heat insulating layer 11 and a foamed concrete layer 12 (not shown) on a slab 20 of a reinforced concrete. And the hot water pipe 13, the finish mortar 14 and the finish board 15 are sequentially installed on the foamed concrete layer 12. [

As a technology for a conventional interlayer noise barrier structure, Korean Patent Laid-Open No. 10-2013-0131518 entitled " Method for constructing an interlayer noise preventing buffer structure and floor structure "has been disclosed. A concrete slab layer having a thickness of ~ 300 mm; A sound insulating material layer 10 to 70 mm thick, a lightweight foam concrete layer 10 to 70 mm thick, It is formed as a finishing mortar layer 30 ~ 70mm thick.

On the other hand, as a countermeasure against the interlayer sound insulation, recently, the housing law was revised and implemented as 2014.05.01. The amendment of this housing law is to strengthen the slab thickness, to induce the laminate structure by the combination of beams and columns, to eliminate the existing standard floor structure, to perform product performance at two different equilibrium locations, If the standard value is satisfied, it is applied to the field.

In addition, the interlayer noise of the building is also related to the wall. Table 1 below shows the results of the quantitative evaluation of the contributions of the floor impact sound to the lower floor.

division Heavy impact sound Lightweight impact sound Contribution Rate by Site Thousand scenes (50.7 ~ 66.0%) The wall (46.8 ~ 63.7%) Wall (28.8 ~ 45.0%) Thousand scenes 25.5 ~ 48.1%) Floor area (2.8 ~ 5.2%) Floor area (5.1 ~ 11.1%)

Such a temperature change easily deteriorates the heat insulating material, 30%), the noise is directly transmitted through the cracks of some slabs, and it is difficult to shield the interlayer noise with the sound insulating material or the foamed concrete layer. In addition, the prior art has no consideration for walls, etc., and thus has a limitation in the effectiveness of interlayer noise cancellation. As a result, it is difficult to satisfy the standard value of the newly revised housing law.
