The present invention relates to a concrete structure that can be usefully used for building a slab of a multi-storey building, and a slab construction structure of a building using the same. In particular, by embedding a liquid receiving bag containing a liquid in the concrete structure, The present invention relates to a concrete structure capable of having sex and dust resistance, and a slab construction structure of a building using the same.

In general, in constructing multi-story buildings such as multi-family houses and apartments, it is common to perform almost all works at construction sites. In the case of apartments, a prefabricated construction method using a press truss method (PC method) has been popular.

Referring to the construction method of a multi-story building according to the prior art as follows.

First, foundation work such as earthwork and ground compaction is performed, and a skeleton structure of a building is formed by using a steel frame such as an H-beam or an I-beam. Specifically, a plurality of steel frames are installed in the vertical and horizontal directions, and then the steel frames are fastened to each other by welding or bracket to form a skeleton structure of the building.

Next, bricks are laid between the vertically installed steel frames or formwork is formed to connect reinforcing bars to the inside, and then concrete is cast and cured to build walls. In addition, the steel frame frame is installed horizontally form a form (eurofoam), the reinforcing bars are connected thereon, and after installing electrical and heating equipment piping, concrete is poured and cured to build a slab (floor).

In this way, after pouring and curing concrete, if a certain period of time after dismantling the formwork is built a layer. Then, several layers are formed by repeatedly repeating assembling, installing, and curing concrete. The building constructed in this way is partitioned by walls and slabs so that several generations can live and have a multi-layered structure, while being divided into several living spaces on one floor.

As described above, in the prior art when placing concrete in the field, air and labor are required a lot, especially in winter, the concrete curing temperature did not meet the cause of the secondary construction.

To solve this problem to some extent, the prefabricated construction method, which produces prefabricated building materials in the factory, produces wallboards and slabs for transport, and transports them to the site by large trailers. How to assemble.

In building a slab of a building, it is important to prevent noise and vibration between floors (bottom and upper floors). In particular, apartments, etc. caused a lot of noise and shock vibration due to the severe fluctuations of the children, causing severe damage to the occupants living on the lower floor. In order to prevent noise and vibration between the layers, a sound insulating material such as a rubber material or a synthetic foam material is installed in the slab.

However, the slab according to the prior art has a problem that can not block the effect of noise and vibration generated in the upper floor even if the sound insulating material as described above. As a result, privacy cannot be secured among tenants in the same building, and distrust and disputes are not ceased due to noise / vibration pollution.

The present invention has been invented to solve the problems of the prior art as described above, the concrete structure having excellent soundproofing and soundproofing (excellent sound absorption and vibration resistance) with excellent absorption performance against noise and vibration, and buildings using the same The purpose is to provide a slab construction structure.

In order to achieve the above object, the present invention provides a concrete structure, the liquid containing bag is embedded in the concrete structure.

According to the present invention, the liquid receiving bag 10 as described above has excellent soundproofing and dustproofing. Specifically, in the multi-story building, the noise of the lower floor may be mainly caused by the impact sound and vibration transmitted from the upper floor. In this case, the impact sound and vibration generated from the upper floor may be liquid (eg, water) contained in the liquid receiving bag 10. As it passes through, it is calcined, absorbed and dispersed (exhausted), and effectively prevented transfer to the lower layer.

One liquid receiving bag 10 as described above may be embedded in a concrete structure, but preferably two or more are embedded at regular intervals as shown in FIG. 2. 2 illustrates the three liquid receiving bags 10 embedded in the horizontal direction.
