Description

Structural layered vibration isolation material for buildings {Structure of vibroisolating material for building}

The present invention relates to a laminated structure of an interlayer dustproof material for a building, and in particular, by forming an interlayer dustproof material buried between a floor slab and foam concrete of a building in a multi-layer structure divided into a high density layer, a medium density layer, and a low density layer, The present invention relates to an interlayer dustproof material laminated structure for improving vibration insulation and sound absorption performance according to the change and effectively reducing the impact noise of light weight and weight.

In general, buildings such as apartments and apartments, which share floors and walls, have high floors, and use floor slabs as lightweight materials or thin floors to reduce weight. There was a disadvantage that does not meet.

Therefore, in view of the above problems, in the past, as shown in FIG. 1, after laminating the interlayer dustproof material 4 on the top of the floor slab 1, the foam concrete 3 and the finishing mortar in order on the top of the interlayer dustproof material 4, (2) is laminated one by one, and the interlayer noise is reduced through the above-described interlayer dustproof material 4.

As the interlayer dustproof material 4 performing the above-described role, a styrofoam dustproof material, a dustproof material to be sprayed using a pulverized product (waste tire), and a dustproof material by foaming of a single material are used depending on the contractor.

Schirofoam dustproof material has excellent insulation effect but is weak to the sound of walking on the upper floor (heavy impact sound), and especially because it is regulated as a dangerous factor in fire, it is not widely used and the thickness should be 2-3 times of the dustproof material to secure performance. It has the disadvantage of being weak in water.

The dustproof material to be sprayed using crushed materials (waste tire) has the disadvantage that not only the characteristics differ greatly due to the mixing of the materials but also weak to the impact sound of light weight. In the case of negative, the effect is greatly reduced and the cracks on the bottom surface after the construction was severe.

Such conventional interlayer dustproof materials 4 have the advantage of reducing the impact noise to some extent, but all have a single structure, and since there is no change in density, the overall vibration insulation and sound absorption performance is deteriorated, and thus may occur frequently. There are various problems that do not effectively reduce the impact noise of light weight and weight.

Accordingly, an object of the present invention is to conceive in view of the above-described conventional problems, by forming an interlayer dustproof material buried between the floor slab and foam concrete of a building into a multi-layer structure divided into a high density layer, a medium density layer, and a low density layer. In addition, to improve the vibration insulation and sound absorption performance according to the density change of the multi-layer structure, and to provide an interlayer dustproof material laminated structure for effectively reducing the impact noise of light weight and weight.

As a means for achieving the above object, the present invention, the interlayer dustproof material is formed with a high-density layer formed of synthetic rubber damping sheet at the top is formed irregularities at the top and a predetermined interval at the bottom, the center of this high-density layer The low density layer made of cross-linked PE foam and the low density layer made of non-crosslinked PE foam are thermally compressed to form a multi-layer structure at the bottom or top and bottom thereof.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a block diagram showing the installation state of the interlayer dustproof material according to the present invention, Figure 3 is a sectional view of the main portion of the interlayer dustproof material showing an embodiment according to the present invention.

In the interlayer dustproof material 100 of the present invention, in the state in which the interlayer dustproof material is stacked on the top of the floor slab 10, the foam concrete 30 and the finishing mortar 20 are sequentially constructed on the top to reduce the interlayer noise. It is the same as before.

However, according to the present invention, it is possible to more effectively reduce the interlayer noise. The interlayer dustproof material 100 according to the present invention has a multilayer structure as shown in FIG. 2 and is required to have a different density from each other.

To this end, an unevenness 111 is formed at an upper portion thereof, and an air layer 112 is formed at regular intervals at a lower end thereof, and a high density layer 110 made of a synthetic rubber vibration damping sheet is provided. The upper and lower middle density layer 120 made of cross-linked PE foam and the low density layer 130 made of non-crosslinked PE foam are thermally compressed to form a multilayer structure.

The synthetic rubber vibration damping sheet has a soundproofing effect and excellent dustproofing performance by increasing the density by mixing the synthetic rubber EVA and fillers, has a flexible, excellent impact strength and rubber-like properties. PE foam has excellent thermal insulation effect, and is excellent in absorption of sound energy and vibration energy by foaming property and density can be adjusted according to foaming magnification.

The unevenness 110 formed on the top of the high density layer 110 increases the contact area between the interlayer dustproof material 100 and the foamed concrete 30 to make the casting better and to form the solid transfer sound as a bending wave, thereby increasing the transmission loss. It serves to reduce the vibration and noise, and the air layer 112 formed at the bottom performs the role of reducing the sound pressure by reducing the sound pressure while passing through the air layer 112 when the impact sound is applied to the floor.

Here, the layered structure of the interlayer vibration damper 100 is not limited to the lamination of the medium density layer 120 and the low density layer 130 in order at the bottom of the high density layer 110, as shown in FIG. If possible, as shown in FIG. 3, the middle density layer 120 and the low density layer 130 are formed at the top and the bottom of the high density layer 110, respectively. It is to be noted that the lower density layer and the lower density layer can be used in a lamination.

In order to use the present invention configured as described above, first, the synthetic resin vibration damping sheet is extruded to a high density, and then the synthetic resin vibration damping sheet, the crosslinked PE foam, and the non-crosslinked PE foam are transferred and laminated, and then thermocompressed. Then, the interlayer dustproof material 100 having a multilayer structure of the high density layer 110, the medium density layer 120, and the low density layer 130 is formed, and the interlayer dustproof material is cut and packaged and distributed in the market.

Here, the peripheral technology of extrusion molding, thermocompression, cutting, and packaging of the interlayer dustproof material 100 is a technical content that is commonly used, so a detailed description thereof will be omitted.

On the other hand, the interlayer dustproof material 100 is laminated on the bottom slab 10 as in the conventional construction method, the foam concrete 30, the finishing mortar 20 is sequentially installed thereon.

When the impact is applied to the floor in the above state, the interlayer dustproof material 100 has a multilayer structure of the high density layer 110, the medium density layer 120, and the low density layer 130, and thus there is a difference in density change from each other. Insulation, light weight, and heavy sound are reduced, and in detail, sound pressure is reduced in the course of passing the bottom impact sound through the unevenness 111 and the air layer 112 to reduce the interlayer noise.

As described above, according to the present invention, the interlayer dustproof material buried between the floor slab of the building and the foam concrete is formed in a multilayer structure divided into a high density layer, a medium density layer, and a low density layer, so that the density change of the multilayer structure when using the same As a result, the vibration insulation and the sound absorption performance are greatly improved, and the light and weight impact noise can be effectively reduced.

The present invention has been described above with reference to specific preferred embodiments, but the present invention is not limited to the above embodiments and various changes and modifications may be made by those skilled in the art without departing from the gist of the present invention. Make sure you can.
