Description

This paper proposes a new structure for reducing noise between floors and reducing noise between floors.

The present invention relates to a process for installing an interlayer noise reduction structure and an interlayer noise reduction structure, and more particularly, to a process for installing an interlayer noise reduction structure and an interlayer noise reduction structure capable of reducing noise generated between layers of a building.

Since 7.5 out of 10 households in Korea live in apartment houses and 4.5 of them live in apartments, the problem of floor noise generated in apartments is becoming an important social issue. The main reason for the occurrence of the interlayer noise generated in the apartment is that the apartment is a floor slab structure that shares the wall structure (the integral structure of the wall and the floor) and the lower layer of the upper layer and the upper layer of the lower layer. In order to solve this problem, a multilayered structure with multiple layers of cushioning material and a floating floor structure separating the noise source from the floor slab have been developed.

However, the conventional technology has a problem that the floor finish layer becomes thicker and the number of apartment floors is reduced and the construction cost is increased in order to secure the ceiling height of the apartment. Due to this, recently, it has been constructed as a standard floor structure of apartment house composed of concrete slab, cushioning material, lightweight foamed concrete, and finish mortar.

Here, lightweight foamed concrete is a kind of concrete which is used as a substitute material to solve problems such as difficulty in supplying pea gravel, making a lot of porous bubbles in concrete without light aggregate, lightening the weight, and improving heat insulation and soundproofing. However, the lightweight foamed concrete used in the standard floor structure of the apartment house caused the difference between the numerical thermal conductivity and the thermal conductivity after actual pouring depending on the field mixing condition and the skill of the laborer. Also, the lightweight foamed concrete was dried and shrunk due to curing and cracks were generated, thereby causing a problem of water bridging in the mortar layer laid on the upper part of the lightweight foamed concrete later, causing a thermal bridge phenomenon.

An object of the present invention is to solve the above problems by disposing a separate interlayer noise reduction structure instead of lightweight foamed concrete so as to uniformly reduce the interlayer noise while maintaining the existing layer height.

Due to the inclination of the connection part 420, the heating pipe 800 can be easily inserted into the fixing space S410.

In addition, the cylindrical portion 411, the connecting portion 420, and the receiving portion 430 may all be made of the same material.

For example, the cylindrical portion 411, the connection portion 420, and the receiving portion 430 may be made of an elastic material.

9 is a perspective view of a fixing pin provided in an interlayer noise reducing structure according to another embodiment of the present invention.

9, the receiving portion 1430 of the fixing pin 1400 may be formed obliquely to facilitate insertion of the receiving portion 1430 into the sound-emitting groove 510 (see FIG. 4).

The receiving portion 1430 may be formed to be inclined from one end portion connected to the connecting portion 1420 toward the other end portion of the receiving portion 1430.

As shown in the figure, the receiving portion 1430 may be formed such that the upper surface thereof is inclined. However, the upper and lower surfaces of the receiving portion 1430 may be inclined.

Since the receiving portion 1430 is inclined, the receiving portion 1430 can be easily inserted into the sound insulating groove 510.

In addition, since the receiving portion 1430 is inclined, an external force can be effectively applied to the sound insulating material 500 (see FIG. 4) in a state where the receiving portion 1430 is inserted into the sound insulating groove 510.

FIG. 10 is a view for explaining a state in which a fixing pin provided in an interlayer noise reducing structure according to another embodiment of the present invention is fastened to an upper layer. FIG.

10, the fastening part 2412 of the fixing pin 2400 may further extend from the end of the cylindrical part 2411 of the fixing pin 2400. [ Therefore, when the fixing pin 2400 is coupled to the upper layer 110, an opening space may not be provided.

That is, when the heating pipe 800 is coupled to the upper layer 110 by the fixing pin 2400, the fixing pin 2400 is connected to the heating pipe (not shown) in the circumferential direction of the heating pipe 800 800).

Accordingly, when the heating pipe 800 is fixed to the main body by the fixing pin 2400, the coupling pipe 2412 is connected to the heating pipe 800 through the opening space, Down direction.

Specifically, after the heating pipe 800 is fixed to the upper surface of the upper layer 110 by the fixing pin 2400, the mortar can be poured. During the mortar curing, the heating pipe 800 may descend in the direction of the upper layer 110 due to its own weight.

The coupling part 2412 effectively solves the problem by effectively fixing the heating pipe 800.

Hereinafter, the process of installing the interlayer noise reduction structure using the interlayer noise reduction structure according to the present invention will be described.

1 to 5, the step of installing an interlayer noise reduction structure includes the steps of providing a first layer F1 blocking or interrupting the interlayer noise on the first concrete C1 partitioning the layers, Filling the body part 100 with the first material 200, installing the body part 100 filled with the first material 200 on the first layer F1, A step of fixing the heating pipe 800 to a predetermined position of the main body 100 by using the fin 400, a step of pouring the second material 300 on the main body 100, And may include curing the material 300.

This manufacturing method does not use the conventional lightweight foamed concrete, so that it is possible to omit the time for the lightweight foamed concrete to be cured. This makes it possible to shorten the construction time in the past.

In addition, since the heating pipe 800 can be fixed to the main body 100 by the fixing pin 400, the heating pipe 800 can be easily installed.

In addition, since the fixing pin 400 is fixed at a predetermined position of the main body 100, the position of the heating pipe 800 can be easily set.

In addition, the conventional lightweight foamed concrete is shrunk and dried during the curing process, so that the water contained in the second material 300 is drained during the curing of the second material 300. This resulted in thermal bridging.

Since the present invention does not use lightweight foamed concrete, such a heat bridging phenomenon can be effectively solved.

In addition, the process of installing the interlayer noise reduction structure may include a second concrete (C2) partitioning a space in the same layer and a second concrete (C2) covering a space between the first layer (F1) (700), and inserting the body part (100) filled with the first material (200) into a sealing part (710) formed as a groove in the finishing part (700) .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a detailed description of known configurations or functions related to the present invention will be omitted when it is determined that the gist of the present invention may be blurred.
