Description

Composite structural column with improved various performances {COMPOSITE STRUCTURAL COLUMN WITH IMPROVED PERFORMANCE}

The present invention relates to a composite structural column with improved fire resistance and structural performance.

Typical column structures include steel frame (S), reinforced concrete (RC), and steel reinforced concrete (SRC).

Steel framing is a structure in which sections, steel pipes, steel plates, etc. are processed and combined to form a structure by joining members such as columns and beams. The strength of steel materials is serviceability at high temperatures, so the room temperature strength is 500~600℃. About 1/2 of , at 800°C, it becomes almost 0, so fire-resistant coating based on fire-resistant design is necessary. Additionally, steel has the disadvantage of being prone to deformation or buckling due to the length of the member compared to the cross-section.

Reinforced concrete is a complex material that compensates for the insufficient tensile strength of concrete by inserting reinforcing bars into the concrete, but the disadvantage is that the construction process is complicated, including rebar processing/assembly, form fabrication/assembly, concrete pouring/curing, and form disassembly, and the construction period is long. There is.

Steel reinforced concrete is a composite structure in which reinforcing bars are placed around a steel frame and concrete is poured. It is a composite structure that has both the flexibility of a steel frame and the fire resistance and durability of reinforced concrete. However, like the reinforced concrete, construction is complicated and the construction cost is very high. There is a downside.

More specifically, when describing the coupling form of the corner reinforcement connecting member 300 with reference to FIG. 13, first, the end of the coupling bar member 310 is provided on each of the deck members 200 adjacent to each other. 250) or to the outer surface of the flange 102' of the pillar member 100'. In this case, the end of the coupling bar member 310 may be joined to each member by a method such as welding.

In addition, the coupling bar member 310 has one end coupled to the outer surface of the flange 102' of the inner strength bar 250 or the column member 100' provided on the deck member 200, and the adjacent deck. It is arranged to extend in the outer direction of the pillar member 100 so as to pass between the plates 210 of the member 200.

Subsequently, the bent plate 330 is coupled to the other end of the coupling bar member 310 that passes between the plates 210 of the adjacent deck members 200, and as described above, the bent plate 330 is located at the center in the width direction. It can be coupled to the coupling bar member 310 by passing the coupling bar member 310 through a through hole formed in the portion.

Here, the bent plate 330 may be arranged so that both bent ends come into contact with the ends of the plate 210 of the adjacent deck member 200, respectively.

At this time, with both bent ends of the bending plate 330 placed in contact with the plate 210 of the deck member 200, the other end of the coupling bar member 310 penetrating the bending plate 330 is attached. By screwing and tightening the binding members 350, each of the bent both ends of the bent plate 330 can be brought into close contact with the plate 210 of the deck member 200.

In the same manner as described above, a plurality of corner reinforcement connection members 300 are placed between adjacent deck members 200 in a state in which a plurality of deck members 200 are respectively disposed around the outer circumference of the pillar member 100'. When placed respectively, a pouring space (S') where concrete can be poured is formed between the outer surface of the pillar member 100' and the inner surface of the plurality of deck members 200 and the plurality of corner reinforcement connection members 300. .

In this way, the composite structural column 10' according to the second embodiment of the present invention uses a plurality of deck members 200 and a plurality of corner reinforcement connection members 300 to form an outer circumference of the column member 100'. It is characterized in that it is configured so that concrete can be poured into the pouring space (S') formed in the column member (100'), and the fire resistance performance of the column itself is improved by pouring concrete into the pouring space (S') formed around the outer circumference of the column member (100'). By improving this, it is possible to minimize the fire resistance time required for fire-resistant spray paint and fire-resistant paint.

On the other hand, the composite structural column 10' according to the second embodiment of the present invention is formed by curing the concrete poured in the pouring space S', and then connecting the plate 210 of the deck member 200 and the corner reinforcement connecting member. Each of the bending plates 330 of 300 may be provided to be removed from the outer surface of the concrete.

More specifically, the deck member 200 is provided so that the plate 200 is separated from the deck truss girder 230 (de-molded deck member), so that the plate 200 can be separated from the deck truss girder 230 after curing the concrete. In the case of the corner reinforcement connection member 300, the binding member 350 can be removed from the coupling bar member 310 after curing the concrete, and the bending plate 330 can be separated from the coupling bar member 310. It can be configured to do so.

Meanwhile, as shown in FIG. 15, the composite structural column 10' according to the second embodiment of the present invention is provided on the flange 102' side and the web 103' side of the column member 100', respectively. The transverse girder 20 and the longitudinal girder 30 may be combined. For example, the transverse girder 20 may be joined to the flange 102' of the column member 100' by welding or the like. , The longitudinal girder 30 may be installed on the web 103' side of the pillar member 100' in a manner that is fastened to the girder installation member 170' coupled to the pillar member 100'.

The composite structural column 10' according to the second embodiment of the present invention described above has the advantage of improving not only the fire resistance performance of the column but also the structural performance of the column, enabling economical space utilization with a minimum cross section. .

In addition, safety accidents can be prevented because there is no work such as rebar assembly or form installation on site due to prefabrication and assembly at the factory, and the construction period can be shortened because there is no work such as rebar assembly and form installation through factory prefabrication and assembly and on-site installation. There is an advantage.

In addition, since various facility conduits are installed in the space of the column member 100 and the deck member 200 before pouring the concrete, there is an advantage in that the environment and maintenance of the column structure are efficient because there is no external exposure of the various facility conduits.

In the above, even though all the components constituting the embodiment of the present invention have been described as being combined or operated in combination, the present invention is not necessarily limited to this embodiment. That is, as long as it is within the scope of the purpose of the present invention, all of the components may be operated by selectively combining one or more of them.

The above description is merely an illustrative explanation of the technical idea of the present invention, and various modifications and variations will be possible to those skilled in the art without departing from the essential characteristics of the present invention. Accordingly, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention, but are for illustrative purposes, and the scope of the technical idea of the present invention is not limited by these embodiments. The scope of protection of the present invention should be interpreted in accordance with the claims below, and all technical ideas within the equivalent scope should be construed as being included in the scope of rights of the present invention.
