Description

[0001] PREFABRICATED FORMWORK OF REINFORCED CONCRETESTRUCTURE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-disassembly die making technique, and more particularly to an improved beam structure. More particularly, the present invention relates to a new beam structure capable of forming a mold for constructing a pillar or a slab, as well as a mold for fabricating a ceiling beam with a bottom plate and a side plate, and a mold making technique using the same.

In order to make a concrete structure to a certain shape or size, a hardened concrete is poured into it, and a temporary structure that cures until it reaches strength is used at a construction site, which is called a form or a mold.

Generally, a conventional beam structural formwork is composed of a bottom plate and side plates welded to both sides of the bottom plate. FIG. 1A is a view showing a prefabricated beam component for forming a mold according to the prior art.

Referring to FIG. 1A, in the prior art, when the deck plate of the slab deck main body direction member is fixed, the distance between the folded mountains is deformed due to side pressure due to the weight of the slab concrete. In addition, there is a problem that deformation of the corner portion side due to the torsional reaction force occurs, and particularly, it is deformed during the material field and transportation during the automatic molding.

In addition, referring to FIG. 1B, when the side plate according to the related art is packaged and moved, the height of both ends of the component member is not uniform, which causes a problem that the package is opened and the package volume is increased.

Referring to FIG. 1C, in the prior art, since the cutting process is required for joining the joints to each other at the step of joining the side plate and the side plate vertically, there is a problem that the steel plate material is unnecessarily wasted. In addition, the prior art has a problem of a construction finish where protrusions are generated in the outboard direction when the plates are joined to each other.

A first object of the present invention is to provide a basic unit structure of a prefabricated beam that can be applied to a beam form, a column form, a wall form, and a slab form.

A second object of the present invention is to provide a basic unit structure of a prefabricated beam in which, in addition to the above-mentioned first object, welding of the joint is easy and after welding, no apparent protrusion is generated.

A third object of the present invention is to provide a basic unit structure of a prefabricated beam, in which no deformation occurs during transportation and no problem of packing occurs during transportation of the package in addition to the first and second objects.

In order to achieve the above object, according to the present invention, in a prefabricated boom for manufacturing a form, the prefabricated side plate base unit and the bottom plate base unit or a combination thereof are assembled, and the side plate base unit and the bottom plate base unit The side plate base unit is formed by forming a rectangular plate-shaped base plate having a predetermined width (width) (length) and a height (length) Type connecting portion is bent at one end, a C-type connecting portion is bent at the opposite end, one or more B-type mountains are bent between both ends, and the bottom plate basic unit is formed by bending A rectangular plate-shaped base plate having a width (length) and a height (length) of the base plate 210 is formed, and an A-type connecting portion is bent at both ends of the base plate 210 Formed and, the center provides information prefabricated characterized in that the formation of the T-type acid is bent more than one or one.

The A-type connecting portion is formed by folding the end of the base plate to fabricate a first bent surface bent inward so as to be orthogonal to the base plate, folding the first bent surface perpendicularly to the first bent surface, The folded second folded surface 150 is formed and the second folded surface is again folded to form a third folded surface bent inward so as to be orthogonal to the second folded surface so that the first, It forms a "c" shape.

In the C type connecting portion, a first bent surface that is bent inward so as to be perpendicular to the base plate is formed by folding the opposite end of the base plate, and a fourth bent surface is folded so as to be orthogonal to the fourth bent surface, The fifth folded surface is folded so as to be orthogonal to the fifth folded surface to produce a sixth folded surface bent outwardly of the fifth folded surface, 6 The folded surface forms a "C" shape folded outward.

The B-type acid is produced by folding the base plate inward to make the seventh bent surface orthogonal to the base plate, folding the seventh bent surface so as to be orthogonal to the seventh bent surface, The eighth folded surface is folded in the direction opposite to the 180 ° direction so as to overlap with the eighth folded surface, a 10th folded surface is formed so that the 9th folded surface is folded to overlap the seventh folded surface, 10 bent surfaces are bent at right angles to form the remaining portions of the base plate, so that the seventh, eighth, ninth and tenth folded surfaces are folded inward to form an "a" -shaped double-layered mountain.

The T-type acid is produced by folding the base plate inward to make the eleventh bent surface orthogonal to the base plate, folding the eleventh bent surface so as to be orthogonal to the eleventh bent surface, producing a twelfth bent surface bent inward, The twelfth bent surface is folded in the opposite direction by 180 DEG to form a thirteenth bent surface so as to overlap with the twelfth bent surface and the thirteenth bent surface is folded in the opposite direction by 180 DEG to overlap the thirteenth bent surface, Folding the 14th bent surface at right angles to form a 15th bent surface so as to overlap with the 11th bent surface and folding the 15th bent surface at right angles to form the right side portion of the base plate, 12, 13, 14, 15 The folded surface forms a "T" shaped mountain standing perpendicular to the base plate.

The conventional art has a disadvantage in that the deck plate padding fixation interval of the deck main body direction members is narrow and deformation is caused to the side pressure due to the bent mountain spacing distance. Further, the prior art has a problem that deformation occurs due to the cornering reaction force, and deformation occurs during transportation. In addition, in the case of the related art, when the side plate and the bottom plate are welded to each other, it is necessary to perform the operation in an upside-down direction. In addition, there is a problem that the packaging comes up when the side plate is paved, and there is a problem of losing the material due to the necessity of cutting the two-side seam.

On the other hand, according to the present invention, only the deck main-direction direction member is further reinforced with the reinforcing steel angle, and the deformation against the side pressure can be prevented by the reduction of the bent mountain interval. Further, the bending connection portion of the square member corner has the advantage of preventing deformation during transportation and corresponding to the reaction force of the support portion. Further, since the present invention can be jointed and welded on the side, working conditions are easy. Particularly, the present invention can realize all shapes of form beams by combining six kinds of side plates and nine kinds of bottom plates.
