The present invention relates to a dry multi-layered floating structure for reducing noise between floors of apartment buildings. More specifically, the dry-floating method is used to effectively insulate light and heavy weight vibrations between floor slabs and floor forming means of buildings. The present invention relates to a dry multi-layered floating structure for reducing noise between floors of a multi-family house, which absorbs noise and prevents noise from being transmitted to the lower floor through floor slabs and side walls.

In general, buildings such as apartments or apartments that share floors and walls are used as floors for lighter weights or with thinner floors to reduce weight as the floors become higher, so that the impact sound from the upper floors of the building is transmitted to the lower floors. Noise is the most problematic.

The impact sound generated on the upper floor of the building is divided into a light impact sound and a heavy impact sound, and the light impact sound mainly refers to noise generated when an object falls, and the heavy impact sound mainly refers to noise generated when a person runs. The shock applied to the floor structure on the upper floor is vibrated to the slab and then emitted as noise on the lower floor.

Therefore, in order to prevent the impact sound generated in the upper floor of the building from being transmitted to the lower floor, conventional elastic materials such as rubber materials are applied between the finishing mortar, which is constructed on the upper surface, and the floor slab, which is cast with concrete structures. It is a situation to install the interlayer dustproof material or sound absorption material which has.

In the conventional floor inter-floor impact sound blocking structure of the conventional building, the impact sound generated at the upper floor of the building is absorbed and absorbed at the same time as the vibration is insulated by the interlayer dustproof material installed between the finishing mortar and the floor slab, and the impact sound generated at the upper floor of the building is directly absorbed. It is suppressed from being delivered to the lower layer.

However, in the above structure, the impact sound such as the light impact sound and the heavy impact sound is transmitted as it is, and due to the change in the housing culture due to the improvement of the income level, the floor noise of the apartment house, which has been in the category of concession and understanding, which is an oriental virtue, is the right of the tenant. In the recognition of protection, damages are linked to the quality of apartments, and civil complaints are becoming more problematic.

In particular, the slab thickness is increased from 120m / m ~ 130m / m to 180m / m, but it is 210m due to the regulations of the regulations applied after July 1, 2005 and the implementation of the MDU quality class system that induces quality competition between companies. In addition to / m, it can be expected to increase to 240m / m.

In order to improve the above-mentioned problems, various structures for reducing noise between floors of buildings have recently been studied. Among them, Korean Patent Application Publication No. 337780 discloses an example of a sound absorbing member for shock absorption, and a cross-sectional structure thereof. 1 is shown. As shown, the conventional sound insulating member 100 is laminated on the uppermost first fibrous material layer 110 and the first fibrous material layer 110 made of synthetic resin, but made of synthetic resin and irregularly bent a number of A three-dimensional network mat layer 120 forming a mountain and a valley of the second fiber layer 130 made of a synthetic resin laminated on top of the three-dimensional network mat layer 120, and an upper portion of the second fiber material layer 130 The third fiber layer 140 made of a synthetic resin laminated on the styrofoam 150 stacked on the third fiber material layer 140, and the shock-absorbing sound insulating sheet 160 stacked on the styrofoam 150 It is. Here, reference numeral 30 denotes a finish mortar, 32 denotes a heating pipe, and 20 denotes aerated concrete. In addition, the sound insulation member 100 is disposed on the concrete slab 10.

On the other hand, Korean Utility Model Publication No. 312358 discloses a 'layered structure of interlayer dustproof material for building,' the cross-sectional structure is shown in FIG. As shown, the conventional interlayer dustproof material 11 is buried between the floor slab 1 of the building and the foam concrete 12 and the finishing mortar 18 to reduce the interlayer noise caused by the floor impact. After the irregularities 13 are formed and the air layer 14 is formed at regular intervals at the bottom and the high-density layer 15 made of synthetic rubber damping sheet is provided, the lower or upper and lower ends of the high-density layer 15 are centered. The multi-density layer 16 composed of cross-linked PE foam and the low density layer 17 composed of non-crosslinked PE foam are thermocompressed and a multi-layer structure is formed by installing a sheet of PE foam or gypsum board on the side of the building wall. .

As such, the conventional sound insulation or dustproof structure of a building consists of stacking sound absorbing or soundproofing materials and applying an air layer on the concrete slab.

Therefore, the transmittance and the like vary greatly depending on the quality of the air layer and the sound absorbing and insulating material, and thus, the building that wants a high level of anti-vibration effect is not integrally formed and the installation time is excessive due to the individual multi-stage construction. Disadvantages required, and in the conventional impact sound prevention structure, it was difficult to install because there is no space or lack of various pipes and wiring.

In addition, vibrations and noises were transferred to the lower side of the building wall, causing the effect to be halved.

It solves the problems of the interlayer floor impact sound blocking structure of the conventional building which has such a problem, and it is easy to install and the floor slab smoothness is installed because it is a prefabricated structure (dry floating method) in which lightweight foam concrete casting is omitted. Even if you do not do this, you can easily adjust the minor height adjustment later and install it at any time regardless of the external environment (rainy and winter season). It is possible to form a thin layer to provide a dry multi-layer floating structure for reducing the noise between the floors of apartments with excellent economic efficiency.

In addition, the dustproof means 50 is installed to be in contact with the side wall surface of the building to prevent the transmission of noise and vibration. The anti-vibration means 50 is used that is made of a dust-proof rubber 52 is attached to the plate 51 of the same structure as the sound absorbing and insulating means, the anti-vibration means 50 is applied sound absorbing and insulating means ( It is preferable to use the one having the same structure as 20) and attach the anti-vibration rubber 52 to one surface thereof.

Referring to the state of use of the present invention having the structure as described above attached to each other after the rubber member 60 is installed in contact with the floor slab 100 in the state in which each member is coupled as shown in FIG. When the dry multi-layered floating structure is assembled as if the blocks are aligned, the sound absorbing and insulating means 20 forms one bottom surface.
