Description

Formwork for construction and its manufacturing method {a form for structure and manufacturing method}

The present invention relates to a building formwork and a method for manufacturing the same, and more particularly to a new building formwork and a method for manufacturing that can reduce the production process to reduce the production cost and mass production.

In general, in the construction of a building, reinforcing bars are used to form a skeleton, and inner and outer wall formwork is installed on the inner and outer sides of the skeleton, and the inner wall formwork and the outer wall formwork are connected with a connector (commonly referred to as a tie bar). Concrete is poured between the exterior formwork. Subsequently, when the concrete poured between the inner and outer wall formwork is cured for a predetermined time, the inner and outer wall formwork is dismantled to complete the concrete phase.

At this time, the conventional inner and outer wall formwork used is made of wood panels not only takes a lot of time to manufacture, but also most of the damage is in the process of dismantling the formwork after the concrete curing is finished, it is impossible to reuse, in recent years made of metal formwork (Commonly referred to as Euroform) has been standardized and widely used.

Figure 1 shows an example of the inner and outer wall formwork of such a conventional euroform, referring to the inner and outer wall formwork to protrude to one side along the substantially rectangular metal panel (2), both ends of the panel (2). It consists of a strip-shaped side frame 4 to be welded. At this time, the pinhole (3) is formed at a predetermined interval along the longitudinal direction in the central portion of the side frame (4) so as to be assembled with the adjacent formwork, fixed pin (not shown) adjacent to the formwork through the pinhole (3) It is configured to be connected by fastening by).

In addition, a recess 5 is formed on an outer surface of the side frame 4 of the pinhole 3 forming portion, and a tie bar (not shown) for connecting the inner wall formwork and the outer wall formwork through the recess 5 is formed. ) Is configured to be fitted.

FIG. 2 illustrates an inconor formwork, which is an example of another conventional flowform, which refers to a pair of panels 2 welded to form an approximately right angle and cross each other at the ends of the panel 2. It consists of a pair of side frames (4) protruding in the direction.

Reference numeral 6 is a reinforcing rib for reinforcing the strength of the inner and outer wall formwork and the inner corner formwork.

At this time, when looking at the flow-form manufacturing process, such as the inner and outer wall formwork and the inner corner formwork, after cutting the strip member of the metal material produced by extrusion processing to a predetermined length, a plurality of pinholes (3) and recesses (5) in the strip member Machine to form a side frame (4). Subsequently, the side frames 4 are welded to both ends of the panel 2, and then the reinforcing ribs 8 are welded to complete the fabrication.

However, in the conventional flow paths, the worker processes the pinholes 3 and the recesses 5 of the side frame 4 and the side frame 4 is welded to the panel 2 one by one. This increases work time and requires a lot of manpower. There is a problem that the production cost is raised, as well as falling productivity.

The present invention is to solve the above problems, an object of the present invention is to provide a new building formwork and its manufacturing method that can reduce the manufacturing process to reduce the cost, as well as easy mass production.

If possible, the metal plate 14 is bent into a press machine and integrally molded.

Subsequently, the center portion between the bent portions 18 of the wall contact portion 16 is bent at right angles to one side or the other side, and as shown in FIG. 5, the corner mold 12 for placing the corners of the wall 1 and It is configured to be used as an out corner die (13).

Reference numeral 15 is a horizontal reinforcement rib welded to the outer surface of the wall contact portion 16 of the inner and outer wall formwork (10, 11) and the corner formwork (12, 13) at a predetermined interval along the vertical direction.

Therefore, the building formwork (10, 11, 12, 13) is bent at both ends of the metal plate 14 at a right angle, a pair of bending for connecting to the formwork adjacent to the wall contact portion 16 in contact with the wall (1) In addition to forming the portion 18, the bent portion 18 is bent into the pin coupling hole 17, the projection 19 and the projection 19 in the concave portion 19a by pressing equipment to be molded integrally. Therefore, as compared to conventionally manipulating the pinholes and recesses in the side frame by the worker and welding the side frame to the panel, the work is very simple and the manufacturing process is reduced, thereby lowering the manufacturing cost and increasing productivity. Is improved.

Hereinafter, referring to FIG. 6, the process of manufacturing the inner and outer wall molds 10 and 11 and the in-out corner molds 12 and 13 will be described. The fixing pins may be coupled to the molds adjacent to both ends of the metal plate 14. A piercing step (A) for forming a pin coupling hole (17) through which the (8) is penetrated, and a wall contact portion contacting the wall (1) by bending both ends of the pierced metal plate (14) at right angles to each other in the same direction. 16) and the inner and outer wall form-forming step (B) for pouring the wall (1) by integrally press-processing so as to form a pair of bent portions (18) at both ends of the wall contact portion (16).

At this time, in the inner and outer wall form forming step (B), the protrusions 19 are formed to be bent in the longitudinal direction at the inner end and the outer end of the bent portion 18 along the length direction, and the position of the peeling holes 17 of the protrusions 19. The press is integrally formed to form a recess 19a into which the tie bar 9 is inserted to connect the inner dies 10 and 12 and the outer dies 11 and 13.

Therefore, a plurality of reinforcing ribs 15 are welded and adhered along the vertical direction to the other side surface of the wall contacting portion 16 in contact with the wall 1 of the form die having passed through the inner and outer wall form forming step (B). 10, 11) is completed.

At this time, in order to form the in-out corner formwork for placing the corner portion of the wall (1) to form the corner formwork by bending the center portion of the wall contact portion 16 of the form through the inner and outer wall form forming step (B) at right angles to one side or the other side. Go through step (C). Subsequently, a plurality of reinforcing ribs 15 are welded and attached to the outer surface of the wall contacting portion 16 of the in-corner formwork, as in the inner and outer wall formwork 10 and 11, to fabricate the inner corner formwork 12 or the outer corner formwork 13. do.

According to this manufacturing method, the pin coupling holes 17 are formed at both ends of the metal plate 14 at predetermined intervals, and then both ends of the metal plate 14 are bent in the same direction to contact the wall 1. The wall contact portion 16 to be formed and the bent portion 18 for connecting with the formwork adjacent to both ends of the wall contact portion 16 are integrally formed by one press process, and only the reinforcement ribs 15 are welded in a subsequent process. Just attach

Therefore, as compared with the conventional machining of the pinhole and the recess one by one, the operation is very simple and the work process is reduced, the cost can be reduced, as well as the productivity is improved.

In addition, even when forming the formwork for pouring the corner portion of the wall (1), to form a corner formwork by bending the center portion of the wall contact portion 16 of the inner and outer wall formwork to form a corner formwork, simply welding the reinforcing rib 15, the inner corner And out corner die (12, 13) is completed.

As described above, according to the present invention, after forming the formwork for the building formwork such as the inner and outer wall formwork or corner formwork at both ends of the metal plate, the both ends of the form is bent at right angles to the wall contact portion in contact with the wall, adjacent Since the bending part provided with the pin coupling hole, the protrusion part and the concave part can be integrally formed in a single press process so as to connect with the die, the work is very simple and the work process is reduced, thereby reducing the cost and increasing the productivity. There is this.
