Description

TECHNICAL FIELD [0001] The present invention relates to a hollow lightweight module for a deck plate,

The present invention relates to a hollow lightweight body module, and more particularly, to a hollow lightweight body module, in particular, a structure using a reinforced concrete one-piece deck plate, which is easy to install in the field and easy to assemble into a lattice muscle, Lt; / RTI > module.

Recently, various methods have been put into practice to increase the strength by increasing the thickness of the slab and to hollow the inside of the slab in order to improve the weight and the sound insulation performance in order to increase the height of the building or to secure a spacious living room space.

Such a hollow core slab is a structure having a hollow body or a lightweight body at the center, which reduces the weight of the panel and reduces the weight of the slab and has a relatively excellent sectional performance. Such a hollow slab has a long span The advantages of the flatslab are advantageous for reducing the interlayer noise.

As a lightweight body to be installed in such a hollow slab, Korean Patent No. 757960 discloses a unit-type lightweight molding material disposed in a two-direction hollow hollow slab. The hollow slab using the lightweight molding material of the prior art is embedded in the concrete slab in the form of a unit panel spaced apart by a plurality of rows and columns in a state in which a plurality of lightweight molding materials are sandwiched by upper and lower wire meshes or plastic unit frames .

However, in the above-mentioned prior art, since the lattice-shaped lightweight bodies are arranged densely in a lattice-like manner to increase the hollow ratio, and the lattice roots are arranged in the respective lightweight bodies, It is very difficult and uncomfortable to pipe piping such as equipment pipes, which causes a problem that the construction cost of the building is increased due to an increase in workforce and construction period required for piping work.

In order to solve this problem, Korean Patent No. 10-1220128 discloses that a plurality of lightweight bodies can be easily assembled using the connection module as shown in FIG. 1, and a module for a wire bundle is mounted on the connection module or the lightweight body And a space can be formed between the upper surface of the lightweight body and the upper reinforcing bar of the slab. Therefore, a lightweight module capable of facilitating piping work such as a conduit pipe or a facility pipe has been proposed.

However, the conventional lightweight module has a problem in that it is difficult to apply to a reinforced concrete one-piece deck plate slab structure in which truss reinforcing bars are disposed. In the steel reinforced concrete deck plate slab structure, a lightweight body should be disposed between truss reinforcing bars disposed at a predetermined interval. Since a lightweight body should be disposed between truss reinforcing bars, it is difficult to install the lightweight body in a spherical shape, There is a problem in that the hollow ratio is remarkably reduced because it is limited to a size that can be disposed between the truss reinforcing bars when the lightweight body is installed.

In addition, when the lightweight body is arranged between the truss reinforcing bars in the reinforced concrete one-piece deck plate slab structure, it takes a lot of time and cost to align the lightweight body in the direction perpendicular to the longitudinal direction of the lightweight body, There is a problem in that it takes a lot of time and cost to work for buoyancy prevention such as reinforcing bars at the upper and lower portions of the lightweight body and fixing the lightweight body to the reinforcing bars by using auxiliary steel for preventing buoyancy.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a deck plate slab structure for a reinforced concrete one-piece structure which is easy to install in the field and is easy to assemble into trusses, And to provide a hollow lightweight body module capable of not only simplifying and facilitating the operation but also improving the hollow ratio.

In this case, both sides of the connection supporting part are formed by extending a certain length, and both ends of the connection supporting part are bent upward or downward.

Here, the connection support part is formed with a locking protrusion protruding from the surface of the connection support part and fixing the reinforcing bars disposed on the connection support part so as not to be displaced.

Here, the outer surface of the lightweight unit is formed by bending the upper and lower ends, the square corner, and the supporting wall forming part in an arc shape.

According to the hollow lightweight body module for a deck plate of the present invention having the above-described construction, since the lightweight module is simply disposed between the truss reinforcing bars in the reinforced concrete one-piece deck plate slab structure, It is easy to assemble into reinforcing bars or the like, and the work for preventing buoyancy of the lightweight body can be made simple and easy by the constitution of the connection supporting portion.

Further, since the rectangular lightweight module is disposed between the truss reinforcing bars, the hollow ratio can be improved as compared with the case of arranging the rectangular lightweight body, and the lightweight body unit in which the two hollow portions are integrally formed is disposed The hollow ratio can be improved as compared with the case where the lightweight bodies are arranged apart one by one.
