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 cross-

The present invention relates to a unit structure using a concrete-filled column and a cross-shaped connecting member, and a method of constructing the same. More particularly, the present invention relates to a unit structure using a concrete filled column for unit structure, The present invention relates to a unit structure using a concrete filled column and a cruciform connecting member which can be easily connected to a beam and can be manufactured and installed at a low cost as well as an effective cross section, and a construction method thereof.

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 formed into an angular pipe having a square cross-section, the manufacturing process becomes complicated, resulting in a problem of increased production cost. 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 cruciform connecting member which can easily form a concrete filled column for a unit structure and can construct a cross section efficiently as well as a 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 an open end tube so that it can be manufactured in a simple cross-sectional shape. Also, in the column joint, a simple cross- The present invention provides a unit structure using a concrete-filled column and a cross-shaped connecting member, which is more economical, and a method for constructing the unit structure.

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.

Fourthly, the concrete filled column for the unit structure is manufactured by bending a thin plate by forming an open end pipe extending vertically using the open end bent plate 111. In the past, the diaphragm was bent by a bending lap To improve the section stiffness and to ensure the composite performance with the filled concrete.

The steel structure using the concrete filled column and the cruciform connecting material for the unit structure according to the present invention and the construction method thereof are constructed by connecting the concrete filled columns for the unit structure using the cruciform connecting material formed with the simple- (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.

Also, since the column-joint is formed by using the concrete-filled column for the unit structure as the open-section pipe, the cross-sectional efficiency is maximized, and the cross-sectional rigidity and cross-sectional area can be optimized.

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.

2C, a beam 120 (a bent member 120b) having a bottom plate supporting portion 121b formed on a side surface of the lower end section bent plate 111 of the concrete filled column 110 for a unit structure in the unit structure A ) Are directly connected by welding.

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

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 of the vertical plate bent in the form of a horizontal flat 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.
