Description

Floor impact sound reduction structure of building slab {A FLOOR IMPACT NOISE REDUCE STRUCTURE OF BUILDING SLAB}

The present invention relates to a floor impact sound reduction structure of a building slab, and more particularly, to a floor impact sound reduction structure for improving the performance limitation of the existing floor impact sound protection material used in the construction of slabs such as apartment houses.

In general, various floor finishing materials are used in the construction of floors, such as buildings. In particular, in the case of reinforced concrete buildings such as hotels and malls, the floor that divides each space into upper and lower floors is coated with foamed concrete on the slab of reinforced concrete and then finished with cement mortar or artificial stone mortar. In the case of residential buildings, such as single-family houses and apartments, the floor surface is a synthetic resin flooring material having a constant thickness, that is, approximately 1.0 mm to 2.0 mm thickness after the heating pipe is disposed on the foam concrete and finished with cement mortar. The method of apply | coating mororium etc. is employ | adopted.

However, in the reinforced concrete slab structure as described above, the bubble concrete built on the upper surface of the reinforced concrete slab is responsible for attenuating the noise, but the noise attenuation of the foamed concrete absorbs and blocks the noise due to light weight impact and weight impact. In addition, the floor covering made of synthetic resin laid on the upper surface of the finished cement mortar serves to attenuate only about 2 dB of noise level and has a problem of preventing further noise and vibration.

On the other hand, in general, the floor impact noise reduction material of a house is characterized by the performance evaluation, in addition to the floor shock sound insulation, the physical and chemical relationship with other materials such as concrete, the structural performance against the load acting on the floor, and the floor impact sound reduction. Various performance and construction problems such as elastic properties of the material, heating piping and resistance to the surrounding thermal environment should be reviewed and audited in a comprehensive manner, and all of the complex performance requirements listed above should be met. I make it contents.

However, conventionally, when the elastic modulus of the material or structure to block the floor impact sound is small, it is pressed and compressed by the fixed load of the upper part of the dustproof material layer, so that it does not effectively block the impact force due to the impact load. Increasing the thickness of the material layer has a problem that the floor of the occupant has a feeling of jitter and increase the defects of crack generation of the floor.

On the other hand, in the case where the material or structure has a large modulus of elasticity, the transmission of the impact force becomes large, so that it does not have a function as a dustproof material. Especially in the case of heavy shock sound considering sedentary residential culture like Korea.

In addition, even if the proper elastic modulus is found, the difference between the fixed load and the impact load is large, so that the same cross-sectional structure having a single isogas spring constant has a limit of improving sound insulation performance.

Therefore, the present invention is proposed to solve the fundamental causes of the above-mentioned shock and noise transmission, and the floating floor structure for minimizing the direct transmission of the floor shock sound to the structural slab is divided into the fixed load and the impact load so as to be burdened. The purpose is to solve the problems caused by the floor impact sound between neighboring households such as apartments.

The object is to form a single layer of a low elastic modulus mat material and a relatively high elastic modulus load-bearing dustproof material for the soundproof dustproof between the structural slab and the upper slab, the dustproof material comprises a plurality of corners It is possible to achieve through the floor impact sound reduction structure, characterized in that the location is configured to support the upper slab.

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

1 is a cross-sectional view of the slab structure according to the present invention, Figure 2 is an exploded perspective view of the slab structure, Figure 3 shows a perspective view of the dustproof layer according to an embodiment of the present invention, respectively.

That is, as shown in Figures 1 and 2, the building structure according to the embodiment of the present invention is a structural concrete slab (1) made of RC concrete and reinforcement on the lightweight foam concrete layer (2) for insulation and heating ondol pipe ( In the upper slab structure in which the mortar layer (3) on which 4) is installed, and the finishing layer (5), such as a floor covering, are sequentially stacked, in the present invention, each corner portion of the lower portion of the lightweight foam concrete layer (2) An anti-vibration material 11 was formed on the floor to support the load of the upper slabs (2, 3, 5 layers).

At this time, the anti-vibration material 11 is used, such as neoprene rubber having a high modulus of elasticity to adjust the modulus, position and quantity so as to have a proper displacement with respect to the load applied from the upper slab. In Figure 3 it can be seen that the dustproof material 11 is additionally provided as necessary in the center of each edge as well as each corner.

And the remaining portion except the position of the vibration damping material 11 is provided with a mat material 10 of the low elastic modulus excellent in insulation effect and water resistance to form a single dust-proof layer between the upper slab and the structural slab (1).

The mat member 10 is preferably made of a flexible polyurethane foam (flexible polyether polyurethane foam), glass wool, rock wool or the like excellent in sound absorption and thermal insulation performance.

And on the dustproof layer (10, 11) to form a thin PE film 12 for the order to prevent being submerged or contaminated by the lightweight foam concrete layer (2) or mortar layer (3).

In the figure, reference numeral 6 denotes a wall vibration insulating material for preventing the vibration from the slab from being transmitted to the wall.

As described above, the dustproof layer of the present invention made of the dustproof material 11 and the mat material 10 has a floating bottom structure for blocking the floor impact sound by dividing it into a fixed load and an impact load so that the elastic modulus suitable for each load It is applied to the material having a, characterized in that the dust is placed in the periphery of the slab in particular the support part to minimize impact sound transmission to the lower layer. This is the same principle as the occurrence of sound when hitting the edge of the drum rather than hitting the center position when hitting the drum.

If only the dustproof material 11, which is a support part, is placed around, the problem of sag or cracking occurs at the center of the slab, so that the deflection and impact load of the slab may be supported in the remaining space of the dustproof layer. The mat material 10 of the low modulus of elasticity can be placed to solve this problem.

That is, the load supporting dustproof material 11 has a small support area but a large modulus of elasticity, while the low elastic mat member 10 supports a large area even when the elastic modulus is small and absorbs impact force. The floating bottom structure of the shape supported by (11) is formed.

This is because even though a strong impact is applied to the center of the slab, since the upper slab and the structural slab 1 of the central part are almost completely vibration-insulated by the mat member 10, the impact force is a part of the support dustproof member 11. Only through the structural slab (1) is to be transferred to, this support part is located in the periphery of the slab, because the periphery of the slab is constrained by the wall, etc., the rigidity is very large, the principle of the solid sound is limited.

4 and 5 is a schematic diagram of the impact test of the slab structure of the prior art and the present invention according to the building floor impact sound measurement method (KS F2810) determined by the Korea Industrial Standard, the case of the slab structure to which the floor impact sound reduction structure of the present invention is applied As shown in 4, the impact force applied to the central portion by the weight body 20 is transmitted to the structural slab 1 only through the dustproof material 11 at the corner side, but in the case of the conventional slab structure as shown in FIG. As can be seen that the impact force by the weight body 20 is transmitted to the lower slab as it is.

Therefore, according to the slab structure of the present invention, the noise transmission due to the impact load of the floor is very small, it can be seen that the performance limitation of the existing floor impact sound prevention material is improved.

In addition, although specific embodiments of the present invention have been described above, it is apparent that the slab support structure of the present invention may be variously modified and implemented by those skilled in the art.

However, such modified applications should not be individually understood from the technical spirit or prospect of the present invention, and other modified embodiments should fall within the appended utility model claims of the present invention.

As described above, the floor impact sound reduction structure of the present invention is a groundbreaking structure that improves the blockage effect of the floor impact sound by using only the floor sound insulation sound insulation material. It can be seen that it has a very useful effect of reducing delivery.
