Housing using a unit structure (unit modular) is known as an eco-friendly high-tech housing construction method that can facilitate the construction of a house or the expansion and addition of houses, and dramatically reduce construction waste.
Unlike conventional houses, which are constructed in the field, various kinds of interior materials (window, etc.), various mechanical equipments (bathroom and kitchen etc.) and electric wiring are built in the factory in advance in the unit structure composed of a plurality of cubes at the factory, And is assembled and completed.
As the housing is produced at the factory, it is possible to increase the productivity of the construction, to solve the problem of functional manpower due to the 3D phenomenon, to maintain the pleasant and safe construction site, . In addition, a unit structure using a unit structure is constructed by transporting a unit structure having a steel structure to a site and assembling it as a lEGO block, so that it is possible to dismantle the house according to the tastes of the residents and easily remodel the interior.
The housing construction method using the unit structure makes it possible to reduce the construction period, the construction cost and the environmental load to about 30% compared with the existing construction method due to the assembly and the construction of the housing construction. Especially, %.

In addition, when the diaphragm is used, the joining performance and workability in the joining of the column portion can be improved to some extent, but an additional diaphragm is necessary, so that the economical efficiency may be somewhat lowered.
The present invention relates to a unit structure using a concrete filled column and a connecting whorl plate, which can constitute a concrete filled column for a unit structure and which can constitute a cross section efficiently as well as an inexpensive manufacturing cost, And an object of the present invention is to provide a construction method.
That is, the concrete-filled column for the unit structure is manufactured in the form of a bending open end tube so that it can be manufactured as a simple cross-sectional shape. In the column joint, the bending open end tube- The present invention provides a unit structure using a concrete filled column and a connecting marker board and a method of constructing the unit structure by using a concrete filled column for a unit structure as it is.
In order to achieve the above object,
First, in the case of a concrete filled column for a unit structure, an open concrete filled column having one side opened is filled with concrete to simplify the construction of a concrete filled column for a unit structure.
The concrete filled column for the unit structure is used as a column in the unit structure and the concrete filled column for the unit structure is directly connected to the beam and used as a steel structure for a unit structure.
Second, a connection marker board is integrally formed on a bottom surface of a concrete-filled column for a unit structure so that a concrete filled column for the upper and lower unit structures can be easily connected using bolts and nuts. The concrete-filled column for the left and right unit structures can be easily joined using a cross-shaped connecting member connected by using a nut.
Thirdly, in the cruciform connecting member connected to the connecting whorl plate of the concrete filled column for the unit structure, the joining plate is formed at the bending portion, thereby enhancing the concrete filling type column joining performance for the unit structure.
Fourth, the concrete-filled columns for the unit structure are manufactured by bending a thin plate to increase the upper and lower bent portions of the reinforced concrete by using the open section bent plate. In the prior art, It is possible to improve the sectional rigidity and to secure the composite performance with the filled concrete.
A unit structure using a concrete filled column and a connecting whorl plate according to the present invention and a method of constructing the unit structure are constructed by connecting a concrete filled column for a unit structure by using a cross connecting member having a simple connecting structure and a staggered connecting plate, (To improve the sectional rigidity and to increase the composite performance with the filled concrete), while securing workability and workability.
Also, the upper, lower, left, and right joint portions of the unit structure according to the present invention can be assembled and disassembled easily, so that the unit structure can be recycled and reused and can be easily moved.
In addition, concrete filled columns for unit structures can secure the sectional rigidity and fire resistance, and can be manufactured more economically since they are manufactured using thin plate and concrete.
In addition, since the concrete filled column for the unit structure is used as a bended open end pipe which is advantageous for confining concrete, the column joint is formed, thereby maximizing the sectional efficiency and optimizing the sectional rigidity versus sectional area.
Accordingly, the present invention realizes complete fixing between a column and a beam or a unit structure constituting a unit structure of a simpler structure, thereby enabling construction of a unit structure of a residential building having a size of 12 floors or more.
