The present invention relates to a floor impact noise attenuation structure of a multi-story building that absorbs and removes noise generated from an upper floor of a multi-story building such as an apartment, and more specifically, having a damping function on an upper surface of a floor slab layer. The present invention relates to a floor impact noise attenuation structure of a multi-storey building, in which a structure and a heat insulating material are integrally constructed to exhibit a damping performance while having a heat insulating function.

Due to the change in the form of housing according to the development of industry, apartments are gradually getting higher, so noise between floors is becoming a social problem.

If a loud noise occurs in the upper floors during the late night hours, there may be a case of conflict between neighbors due to the noise caused by the floor occupants being unable to sleep properly.

Therefore, recently, apartments that minimize the noise between floors along with the well-being of everyday life are becoming more popular among consumers and are being constructed to reduce noise between floors.

In order to prevent the noise between layers, the insulating material is constructed on the upper surface of the damping material (sometimes, the damping material is applied on the upper surface of the insulating material). It is installed on the upper surface or the lower surface or both sides.

However, this construction method has a limit to attenuate the resonance frequency of the heavy impact sound, so the effectiveness is inferior, and the situation is improving by increasing the thickness of the floor slab layer from 135-150mm to 210mm to improve the weight impact sound.

However, this increase in the slab level does not meet the government's regulation of floor impact sound (50 dB for heavy impact sound, 58 dB for light impact sound) of the multi-family house, or it is expected to be grade 4 (weight impact sound is 50 dB for class 4). , 3dB difference, 1st class is the best grade / light impact sound is only 4dB, 4th grade, 5dB difference, and 1st class is the highest grade). We are very concerned about the attenuation structure.

If the thickness of the floor slab is thick, the height of the floor will naturally increase, and the number of furniture in the same construction area will be small. Is bound to occur.

In addition, the problem of thick floor construction is not limited to this, but the use of cement and aggregates, which are construction materials, has increased, resulting in a serious shortage of materials in our country, which lacks underground resources. This causes the destruction of the environment such as the loss of white sand beaches.

The main reason why the conventional construction method did not reduce the weight impact sound is the low density insulation or insulation buffer installed on the top surface of the floor slab layer and the bottom of the ondol layer. The vibration was amplified to deepen the floor impact sound because it lacked the ability to attenuate the mode frequency peak value of the low frequency band 63 Hz band between the ondol layer generated by the impact, that is, the weight-bearing frequency of the floating floor. Because.

In order to solve this problem, the low density insulation material or insulation buffer material is eliminated, and the damping material containing asphalt, etc., which has a high loss factor, is integrated with the floor slab layer to be thickened and the foam concrete layer and the mortar layer are formed on the upper surface. It is desirable to.

However, the method of thickening certain parts with only the damping material is expensive and it is less effective than the expensive investment because it cannot satisfy the legally regulated heat permeation rate standards.

The present invention has been made in order to solve such a conventional problem, the portion in contact with the floor slab layer provides a structure consisting of a soft damping member and the weight impact sound is applied to the interior of the structure to accommodate the insulating material having a thermal insulation function The damping member is to attenuate the purpose and to ensure that the insulation of the bottom layer is made by a heat insulating material embedded in the interior of the structure.

According to an embodiment of the present invention for achieving the above object, by forming a plurality of spaces having a size of 5mm or more in the structure that is in contact with the floor slab layer is a soft structure to embed the heat insulating material in each of the spaces, A hollow layer is formed on the upper side, and a floor impact noise attenuation structure is provided on the upper surface of the structure, wherein a plate made of any one material of metal, synthetic resin, thick paper, inorganic or inorganic compound is positioned. .

According to another embodiment of the present invention, a space portion having a size of 5 mm or more is formed in a structure in which the upper portion is closed to embed a heat insulator in the space portion, and a soft damping member is installed on the bottom surface of the structure to contact the floor slab layer. There is provided a floor impact noise attenuation structure of a multi-story building, characterized in that a hollow layer is formed between the insulating material and the damping member embedded therein.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 1 to 6 as an embodiment.

1 is an exploded perspective view showing a first embodiment of the present invention, Figure 2 is a longitudinal sectional view showing a first embodiment of the present invention is constructed, Figure 3 is a longitudinal sectional view showing a first embodiment 1-1 of the present invention, According to the present invention, a plurality of space portions 1a having a size of 5 mm or more are formed in the structure 1 made of a soft portion in contact with the floor slab layer 2, and the heat insulating material 3 is embedded in each of the space portions. On the upper side of the heat insulating material 3 embedded in the space 1a, a hollow layer 4 is formed so that the heavy impact sound acting on the structure 1 is not transmitted to the bottom slab layer 2.

The reason why the hollow layer 4 is formed inside the structure 1 is to allow sufficient thermal insulation function as well as absorption and reflection of the applied impact energy.

As the material of the structure 1, a soft or hard synthetic resin (chemical product) may be used as needed, or a synthetic resin mixed with soft and hard may be used.

In addition, since the vermiculite, foamed chemicals or by-products thereof, finely crushed chips, etc. may be used as a material of the heat insulating material 3 filled or inserted into the space 1a formed in the structure 1. It is not necessarily limited thereto.

The height of the space (1a) formed in the structure (1) is at least 5mm, the size is 5mm or more in diameter when the space is circular, the length of one side should be 5mm or more in the case of polygonal insulation performance, Sound absorption effect can be expected.

And the upper surface of the structure (1) is located a plate 5 made of a material of any one of metal or high density inorganic or inorganic compound, artificial wood, wood wool, wood cement, synthetic resin, thick paper.

At this time, the plate 5 may be manufactured in the form of a flat plate, but an embossing protrusion 5a such as a circle or a polygon may be formed on the upper surface in order to improve adhesiveness with the bubble concrete 6.

The reason for placing the plate 5 on the upper surface of the structure 1 is to prevent the bubble concrete 6 from flowing into the inside of the hollow layer 4 in the course of construction, as well as to prevent impact energy from being applied. This is to prevent the vibrations from spreading quickly.

The first embodiment of the present invention having the above-described structure allows the structure 1 to be connected to the bottom slab layer 2 as shown in Figs. 1 and 2 and then the vermiculite, foamed chemical product or Inserting or filling the insulating material (3) made of these by-products, chips, etc. shredded, it is to insert the insulating material (3) so that the hollow layer (4) is formed on top of the insulating material (3) very important.

The structure 1 is constructed in turn over the entire floor of the building.

Subsequently, a plate 5 made of any one of metal or dense inorganic or inorganic compound, artificial wood, wood wool, wood cement, synthetic resin, and thick paper is placed on top of the structure 1, and then foamed concrete. After filling the (6) to form a bubble concrete layer, the pipe (7) is laid and the mortar (8) is filled to form an ondol layer.

In the drawings, reference numeral 9 denotes a floor finishing material such as a floor covering or a floor, and 10 denotes a side cushioning material.

However, when the case 11 having the plurality of space portions 11a is installed on the upper surface of the plate 5 and the heat insulating material 12 is built in the space portion 11a of the case 11 as shown in FIG. Since it is not necessary to fill the concrete (6) it is possible to semi-dry construction, thereby reducing the floor thickness has the advantage of further increasing the insulation effect.

At this time, the material of the case 11 can be applied to any one material of a metal or a high density inorganic or inorganic compound, artificial wood, wood wool, wood chips, synthetic resin, such as the material of the plate (5).

4 is a longitudinal cross-sectional view showing the first and second embodiments of the present invention, in which the damping member 13 having a thickness of 1 mm or more is provided on the upper surface of the plate 5 in the state shown in FIG. 2.

As the damping member 13, a material containing dustproof rubber or asphalt components may be used.

When the damping member 13 contains asphalt components, as shown in FIG. 6, the oil evaporates at least one surface of PE foam or vinyl on at least one of upper and lower surfaces so that oil does not evaporate and loses its function as a damping member. The prevention member 14 should be attached.

On the other hand, when the plate (not shown) made of any one of the metal, synthetic resin, thick paper, inorganic or inorganic compound as shown in Figure 1 on the upper surface of the damping member 13, the effect of attenuating the heavy impact sound It will be further improved.

This is because as the stiffness (weight) of the attenuation structure increases, the vibration is more effectively attenuated.

5 is a longitudinal sectional view showing the first to third embodiments of the present invention, in which the portion of the structure 1 which is in contact with the bottom slab layer 2 is made of soft 1b, and the portion of which the plate 5 is in contact is hard. (1c).

On the other hand, in order to increase the damping efficiency, a damping member (not shown) having a thickness of 1 mm or more may be further provided on at least one surface of the top surface of the bottom slab layer 2 or the bottom surface of the foamed concrete 6.

In addition, the floor slab layer (2) located on the bottom surface of the structure (1) because there is a risk of slight irregularities on the upper surface of the floor slab layer (2) during the construction of the structure (1), or foreign matter such as sand may be interposed. It is more preferable to provide a sheet of PE or polyester material (not shown).

However, without installing PE or polyester sheets on the bottom slab layer 2, sand, stone powder, tire chips, or the like may be laid or mixed, and the structure 1 may be installed thereon.

7 is a longitudinal cross-sectional view showing a second embodiment of the present invention, Figure 8 is a longitudinal cross-sectional view of the damping member is coupled to the bottom surface of the structure in a second embodiment of the present invention and Figure 9 is a 2-1 of the present invention As a longitudinal cross-sectional view showing an embodiment, the second embodiment of the present invention differs from the first embodiment in that the upper surface of the structure 1 is closed and a separate damping member 15 is provided on the bottom surface.

That is, the space 1a having a size of 5 mm or more is formed in the structure 1 with the top closed, and the heat insulating material 3 is built in the space part, and the bottom slab layer 2 and the bottom surface of the structure 1 are formed. The soft damping member 15 which abuts is installed, and is comprised so that the hollow layer 4 may be formed between the heat insulating material 3 and the damping member 15 built in the space part 1a.

In the second embodiment of the present invention, vermiculite, foamed chemicals or by-products thereof, finely crushed chips, or the like may be used as the heat insulating material 3 as in the first embodiment.

In the second embodiment of the present invention, the upper surface of the structure 1 is closed so that it is not necessary to use the same plate material as the first embodiment.

Therefore, when a heavy impact sound is applied on the upper side of the structure 1, the applied impact sound is not transmitted to the bottom slab layer 2 through the heat insulating material 3 by the hollow layer 4, and the damping member 15 through the structure 1. To be attenuated.

In this case, the damping member 15 installed on the bottom of the structure 1 may be directly fixed by using an adhesive or the like, but as shown in FIG. 8, the coupling protrusion 1d is formed on the structure 1 and the damping member 15 is formed. ) May form a coupling groove 15a to fix the damping member 15 to the structure 1.

On the other hand, the heat insulating material 3 may be built in the space part 1a formed by closing the said structure 1 to the lower part like FIG.

In this case, since the damping member 15 cannot be coupled to the bottom of the structure 1, the damping member in the form of a sheet is laid on the bottom slab layer 2 to be constructed.

Although the technical spirit of the present invention has been described in detail according to the above-described preferred embodiment, it should be noted that the above-described embodiments are for the purpose of description and not of limitation.

In addition, it will be understood by those skilled in the art that various changes can be made within the scope of the technical idea of the present invention.

As described above, the present invention has the following advantages over the conventional structure.

First, the damping member is provided on the bottom of the structure in which the heat insulating material is embedded, so that the weight shock sound is rapidly attenuated even if the weight shock sound is applied, thereby sufficiently reducing the weight shock sound without thickening the floor slab layer.

Second, since the insulating material having a thermal insulation function is accommodated inside the structure, a low-density thermal insulating material is not compressed even as time passes, so that a continuous thermal insulation effect can be maintained, thereby thinning the bubble concrete layer.

Third, when installing a case with a built-in insulation on the upper portion of the structure it is not necessary to provide a bubble concrete layer it is possible to semi-dry construction.

Fourthly, by carrying the product produced in the production line to the construction site, the workability is greatly improved.
