Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit structure using a concrete filled column and a connection board,

The present invention relates to a unit structure using a concrete filled column and a connecting whorl plate, and a method of constructing the unit structure. In particular, a concrete filled column for a unit structure, which is manufactured by pouring an inner concrete into a bent- The present invention relates to a unit structure using a concrete filled column and a connecting warp plate, and a method of constructing the unit structure.

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, %.

1A, the unit structure A is formed as a two-layer structure on the base 1, and the unit structure A is joined up and down. It can be seen that they are bonded.

At this time, it can be seen that the unit structures A are joined to each other in left, right, top, and bottom, and the joints 4a, 4b, and 4c are generated.

The unit structure A is a steel structure made up of columns and beams. The structure of the joints between the columns and beams will be described with reference to FIG. 1B.

First, the column 10 is manufactured in the form of a closed square tube, and it can be seen that the four columns are connected to each other by fasteners such as bolts and nuts using the cross-shaped connecting member 15 and the connecting bracket 14.

In particular, since the connection bracket 14 is installed at a portion where the beam 13 and the column 10 are connected to each other, the connection bracket 14 functions to reinforce the connection portion, I have.

In addition, it has a function of allowing a large number of beams to be installed on the column up and down through the vertical alignment of the beam.

However, when the column 10 is manufactured in the form of an angular pipe having a square cross section, the manufacturing process becomes complicated, thereby increasing manufacturing costs. Further, there is a problem that the workability of the joint portion is deteriorated and it is difficult to secure the performance.

In addition, the cross-shaped connecting member 15 is fastened with a bolt and a nut so as to penetrate the column 10, so that the connection operation is exposed to the outside of the column 10 to unnecessarily interfere.

1C shows a cross section of a column 20 made of a conventional CFT (Concrete Filled Tube), which is a column 20 filled with a concrete C in a round steel pipe or a square steel pipe 20, There has been a restriction that excessive manufacturing costs are incurred because the steel plates must be manufactured by welding or cold forming the steel plates.

As shown in FIG. 1d, an open concrete-filled column is disclosed. That is, an open concrete-filled column 40 is disclosed in which a plate material is bent at right angles to form a columnar opening S opened at one side edge, and the concrete C is filled in the columnar opening S.

A concrete-filled column 40 and a diaphragm 50 in which such open concrete filled columns are assembled together and filled with concrete are shown in Figs. 1E and 1F, respectively.

That is, a concrete filled column 40 for a unit structure formed by a closed end pipe filled with concrete C comprises an upper connection plate 51; A lower connecting plate 53; And a bumper member (52) formed between the upper connection plate and the lower connection plates (51, 53) so that the upper surface and the lower surface contact the lower surface and the upper surface of the upper and lower connection plates (51, 53) (C) is filled in the diaphragm (50) so that the beam (60) is connected to the diaphragm (50) by being connected to the abutment surface of the diaphragm Steel structures using concrete filled columns and diaphragms are introduced.

However, the steel structure using the concrete filled column 40 and the diaphragm 50 for the unit structure filled with the concrete (C) is a case where the column joint is formed as a joint of the concrete filled column of the closed end shape It can be seen that the joints using the concrete filled columns of the open end tube type are not disclosed.

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,

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.

Also, since the side surface of the open section bent plate 111 is not large in cross section, the bent member 120a is vertically erected so that the side surface and the open section bent plate 111 side are connected to each other, .

At this time, in order to support the deck 300, it can be seen that the deck supporting portion 121b is formed on the side surface in the form of a horizontal plate folded at the upper end of the vertical plate.

Further, the deck 300 is filled with the bottom plate concrete to form a bottom plate in the unit structure. Of course, the deck 300 includes the concept of a PC (precast concrete), and a bottom plate may be formed without installing the bottom plate concrete.
