The present invention relates to a prefabricated wall structure, and more particularly, to a prefabricated wall structure capable of simultaneously performing the role of a formwork and a reinforcing bar in constructing a concrete wall, and simultaneously forming an insulation material, etc. .

In general, in constructing a concrete wall of a building, it is constructed by assembling a panel for formwork on both sides of the wall and binding hardware such as a spacer, while installing supporting materials on both surfaces and placing concrete by placing reinforcement in the formwork. do. This traditional method requires skilled labor for the work and difficult to shorten the construction period because it is necessary to dismantle the temporary materials such as the support material and the gap maintenance after completion of the concrete wall.

As a prior art for solving this problem, a truss frame system for a wall using a formwork assembly is disclosed in Patent No. 10-0501546. However, the frame body 10 of the above prior art is composed of the main reinforcement (11A, 11B) and the lattice reinforcement (13), which combines one frame and the other by a method such as binding wire or welding. (15) is absolutely necessary, and it is not clear how the main reinforcement and lattice reinforcement are combined. In addition, a separate connection means 40 is required for the combination of the frame 10 and the panel 20, and in this process, complicated follow-up operations such as welding or bolt and nut bonding must be performed again, so it is practically shortened the time. Not efficient

3 to 6, the wall structure 400 may include a truss structure 100, a front panel 200, and a rear panel 300. Since the truss structure 10 is the same as described with reference to FIGS. 1 and 2, a repeated description will be omitted below.

The front panel 200 and the rear panel 300 have a rectangular parallelepiped plate shape and are combined at the front and rear surfaces of the truss structure 100 to form an outer wall. The front panel 200 and the rear panel 300 may be not only plywood of general metal or wood, but also gypsum board or insulation, and further, various walls may be formed using urethane, foam, loess, and gypsum. .

Through holes 211 to 214 and 311 to 315 may be formed in the front panel 200 and the rear panel 300, respectively.

Each through hole is formed at a position corresponding to the front coupling portion or the rear coupling portion of the truss structure 100, and when the wall structure is assembled, the front coupling portion is inserted into the through hole of the front panel 200, and the rear panel ( 300) may be inserted into the rear coupling portion. For example, front coupling portions 10a, 30a, 50a, and 70a may be inserted into through holes 211, 212, 213, and 214, and front coupling portions 20a, 40a in the through holes 312, 313, and 314 , And 60a) may be inserted.

Therefore, there is a need for an additional configuration to facilitate assembly or disassembly while strengthening the coupling between the truss structure 100 and each of the panels 200 and 300.

To this end, according to an embodiment, the length of the front coupling portions 10a, 30a, 50a, and 70a may be formed to be larger than the thickness of the front panel 200. In this case, while a portion including the curved portion of the front coupling portions 10a, 30a, 50a, and 70a protrudes to the outside of the front panel 200, the front coupling portions 10a, 30a protruding from the outer surface of the front panel 200 Insertion spaces (not shown) of a predetermined size may be formed by the inner curved surfaces of 50a and 70a. At this time, by inserting the fixing pins 217 into each of the insertion spaces, the front panel 200 and the front coupling portions 10a, 30a, 50a, and 70a can be firmly coupled. However, in this embodiment, since a portion protruding outside the outer surface of the front panel 200 is formed, it may be obstructed to lay an insulating material or a finishing material outside the front panel 200.

According to another embodiment, the length of the front coupling portions 10a, 30a, 50a, and 70a is the same as the thickness of the front panel 200 as shown in FIGS. 4 and 6, and a guide groove on the front panel 200 (210 to 250) can be formed. The guide groove 210 may be formed to a predetermined depth along a straight line connecting the centers of the through holes 211, 212, 213 and 214 on the outer surface of the front panel 200. At this time, the depth of the guide groove 210 is each insertion space formed by the bottom surface of the guide groove 210 and the inner curved surface of the front coupling portions 10a, 30a, 50a, and 70a. It is enough if it can be inserted. Here, the fixing pin 217 may use a wire made of a metal material, and may be composed of a single long line inserted into all insertion spaces on the guide groove 210 or several short lines inserted into each insertion space.

In this way, the front panel 200 and the rear panel 300 guide grooves (210 to 250, and 310 to 350) are formed and the fixing pins (217, 227, 237, 247, 257) that are inserted into the respective insertion spaces, and Through 317, 327, 337, 347, 357), the truss structure 100, the front panel 200, and the rear panel 300 can be firmly coupled, and a smooth surface without protruding parts on the outer surface of each panel Will be able to maintain. In addition, since the wall structure according to the present invention has a simple configuration, it is convenient to carry and can be easily assembled directly on site.

In the above, the present invention has been described with reference to the embodiments shown in the drawings, but this is only exemplary, and those of ordinary skill in the art will understand that various modifications and other equivalent embodiments are possible therefrom. will be. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
