Abstract

The present invention relates to a steel plate reinforced concrete structure which can mount and separate a steel plate and concrete which are main structural members of a steel plate reinforced concrete structure, and more specifically, to a steel plate reinforced concrete structure capable of separating a steel plate and concrete which can easily check integrity of concrete which is a structure by facilitating separation of a steel plate and the concrete, and easily separate the steel plate and the concrete when tearing down the structure to improve tearing-down constructability. According to the present invention, the steel plate reinforced concrete structure capable of separating a steel plate and concrete is formed by mounting a steel plate (2) on both surfaces of concrete (1) using a bolt or the like as a medium. The steel plate (2) is attached to the concrete (1) on a tie bar (5) comprising a hollow stud (4) embedded in the concrete (1) and a hollow sleeve using large and small bolts (3a, 3b). The large and small bolts (3a, 3b) are mounted or detached from the hollow stud (4) and the tie bar (5) by a screw method through corresponding large and small connection holes (6a, 6b) of the steel plate (2) using corresponding large and small washers (7a, 7b) as media to mount or detach the steel plate (2) from the concrete (1).

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel plate and a concrete,

The present invention relates to a steel plate concrete structure capable of joining / separating between a steel plate and concrete, which is a main structural member of a steel plate reinforced concrete structure. Especially, since the steel plate and concrete are easily separated from each other, And a steel plate concrete structure in which a steel plate and a concrete can be separated from each other, in which disassembly workability is improved by easy separation between a steel plate and concrete when the structure is dismantled.

Generally, in a concrete structure, a steel plate concrete structure refers to a structure in which concrete is poured between double-sided steel plates, and the double-sided steel plates are connected by a tie bar. Studs are attached to the double- Thereby securing the adhesion of the steel sheet.

This steel plate concrete structure has the effect of shortening the air compared with the conventional reinforcing concrete method in which the concrete is installed after the reinforcing bars are installed and the concrete is laid by installing the formwork, Since piping, duct, cable train, etc. which are system facilities can be preassembled and assembled in factory or field production site, it is possible to reduce the amount of construction site, and to improve the construction air of various concrete buildings through mechanized construction and concurrent work with other structures It has the advantage of being able to shorten greatly.

On the other hand, the steel plate concrete structure is constructed in the form that the steel plate surrounds the concrete by the connection of welding, stud and tie bars, so that the inner filling property of the concrete, the occurrence of cracks in the concrete surface, It is not easy to confirm the integrity of the structure during the construction of the concrete building, after the construction, or during the use of the facility.

Also, in the conventional steel plate concrete structure, when the disassembly of the facility is large, the stiffness of the outer steel plate is large. Therefore, when the disassembling / disassembling technique such as cutting and explosion is considered, there is a considerable limitation on the dismantling workability compared to the conventional concrete structure.

Korean Patent Registration No. 10-0667695 (2007.01.05.)

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a steel plate concrete structure in which a steel plate and a concrete The present invention provides a steel plate concrete structure in which concrete is detachable.

 According to an aspect of the present invention, there is provided a steel plate concrete structure in which steel plates are coupled to both sides of concrete through bolts or the like, the steel plate comprising a hollow stud embedded in concrete and a tie bar made of a hollow steel bar sleeve The bolts are attached to both sides of the concrete using bolts and washers, and the bolts are fastened or disassembled into hollow studs and hollow tie bars in a screw manner through the corresponding connection holes of the steel plate.

The steel plate concrete structure in which the steel plate and concrete can be separated according to the present invention is structured such that the steel plates can be separated from the studs and the tie bar which are built in the concrete when the steel plate is connected to the concrete, It is possible to easily perform the safety inspection of the structure by separating the steel plate and the concrete from each other, and also it is possible to easily separate the steel plate and the concrete during the disassembly construction, thereby facilitating the disassembly construction work.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a steel plate, excluding concrete, in a steel plate concrete structure according to the present invention;
2 is an assembled cross-sectional view of a steel plate concrete structure according to the present invention,
3 is a sectional view of a steel plate concrete structure according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view showing only one part of a steel plate module 2 before a concrete 1 is inserted in a steel plate concrete structure according to the present invention. In order to facilitate understanding of the structure of the steel plate concrete structure according to the present invention, Left symmetrical steel plate 2 attached to both sides, and the left steel plate is selected.

2 and 3 show an assembled cross-sectional view and a separated cross-sectional view of a steel plate concrete structure according to the present invention. As shown in the drawing, the steel plate 2 is fixed on both sides of concrete 1 by bolts or the like The steel plate 2 is made of a hollow stud 4 embedded in the concrete 1 and a tie bar 5 made of a hollow sleeve using large and small bolts 3a.3b And the large and small bolts 3a and 3b are attached to the concrete 1 through the corresponding large and small connection holes 6a and 6b of the steel plate 2 through the corresponding large and small washers 7a and 7b, (4) and the tie bars (5) by screwing or separating the steel plates (2) to or from the concrete (1).

The hollow studs 4 and the hollow tie bar 5 are threaded so that the large and small bolts 3a and 3b to be inserted are fastened or separated by a screw method.

On the other hand, through a steel plate 2 having a plurality of connection holes 6a having the same size along the same center line as the hollow of the tie bar 5 having a plurality of internal threads installed in the concrete 1, The corresponding bolts 3a are fastened together. The tie bar 5 is formed in a hollow shape through its entire length, or only a part of the tie bar 5 is hollow.

The hollow studs 4 built in the concrete 1 are also screwed into the corresponding small bolts 2 through a steel plate 2 in which a plurality of small connection holes 6b are drilled in a manner similar to the tie bar 5 described above. (3b) are fastened.

 3 shows a state in which the steel plates 2 are connected to both sides of the concrete 1 as shown in FIG. 2, and the steel plates 2 are connected to the steel plates 2 by releasing the bolts 3a, It can be easily separated from the concrete 1, so that it is possible to perform safety inspection of the structure during operation such as cracking of the concrete 1 and non-destructive inspection of the concrete. If necessary, The work can be easily performed by easy separation between the concrete 1.
