The present invention relates to a hollow concrete structure and a multi-layered building using the same. More particularly, the present invention is usefully used for constructing walls or interlayer slabs of a multi-layered building, and has excellent soundproofing and dustproofing properties. It relates to a hollow concrete structure that can have), and a multi-story building using the same.

Conventionally, in constructing multi-storey houses, villa-type buildings of a tenement house type, building-type buildings having many rental offices inside, and multi-unit buildings such as apartments, schools, hospitals, and dormitories, almost all construction sites Work was universal. 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 is as follows.

First, the foundation work is performed, and the skeleton structure of the building is formed by using steel frame such as H-beam or I-beam. Specifically, a plurality of steel frames are installed vertically and horizontally, and then the steel frame frames are fastened to each other by welding or bracket to form a skeleton structure of the building.

Next, masonry is installed between vertically installed steel frame or assembling prefabricated formwork called Euroform, and the reinforcing bar is connected between formwork, 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 pipes, 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 repeating the assembly, installation and curing of the formwork several times. At this time, the constructed building 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.

Conventionally, since the concrete is poured in the field as described above, a lot of air and labor is required, in particular, in the case of winter, the concrete curing temperature could not be adjusted to cause the sub-work.

To solve this problem to some extent, the prefabricated construction method is to produce the prefabricated building material wall wall and slab bottom plate in the factory and transport it to the site by a large trailer to interlock the wall plate and the bottom plate with a crane in the field. How to assemble.

However, the conventional building construction method as described above, even if the sound insulation material is installed on the floor, there was still a problem that the noise between floors (bottom and upper floor) is severely generated. Accordingly, there is a lack of privacy between tenants in the same building and distrust and dispute between each other due to noise pollution. In addition, especially in apartments, there was a problem of severe damage to the occupants living in the lower floors due to vibration as well as noise due to severe fluctuations of the children.

The present invention has been invented to solve the problems of the prior art as described above, by having a hollow portion therein and by embedding a truss girder for supporting the upper plate and the lower plate, it is excellent by the hollow portion It is an object of the present invention to provide a hollow concrete structure having soundproofing and dustproofing properties and at the same time having excellent support strength by the truss girder, and a multi-layered structure constructed using the same.

In addition, the concrete structure according to the present invention preferably has an assembly means so as to be firmly assembled with the concrete structure adjacent to each other. In addition, the heat insulation / sound absorbing material and the piping line is preferably installed inside the state in which the hollow part is secured, and a shock absorbing member or a hole may be installed as a means for minimizing the impact. At this time, the hole serves to absorb the shock and at the same time induce heating.

It is also useful for building slabs between walls and floors of multi-story buildings. At this time, noises and vibrations between the walls and the layers are exhausted by the hollow part, so that they have excellent soundproofing and dustproofing. In addition, the concrete structure itself has excellent strength by the truss girder.

At this time, the end of the truss girder 30 is embedded in the lower plate 14 before the concrete is hardened, and then completely cured by hardening. And the lower plate 14 is installed and fixed to the heat insulating / sound absorbing material 50 and the piping line 60. At this time, in installing the pipe line 60, a hole is drilled so that the end 61 of the pipe line 60 is exposed to the outside through the hole as shown in Figure 8a. In addition, a hole 72 is formed by drilling with a drill. This hole 72 can be formed by inserting a pipe into a mold before placing concrete, without drilling by drilling.

Next, as shown in Figure 8b, by using a mold (die) to produce a top plate 12 separately from the above semi-finished product (100-1). At this time, as shown in Fig. 8c, before the concrete constituting the top plate 12 is completely hardened, the semi-finished product (100-1) is inverted and stacked for the top plate 12 of the truss girder 30 on the top plate 12 Allow the end to be embedded. And when fully cured and hardened concrete, the semi-finished product (100-1) and the upper plate 12 is integrated to produce a concrete structure 100 of the structure shown in FIG.

In addition, in the manufacturing process as described above, the insert (not shown) is inserted into the side plate 16 of the semi-finished product 100-1 and the top plate 12 so that the bonding force of the semi-finished product 100-1 and the top plate 12, the top plate 12 At the edges of the), a bolt hole (not shown) may be formed to fasten and couple the semi-finished product 100-1 and the top plate 12 with bolts (not shown).

Concrete structure 100 according to the present invention completed as described above is spread to the construction site, it is usefully used for building walls or slabs of multi-layered buildings.
