Technical Field

The present invention relates to a formwork coupler for fixing the formwork panel consisting of formwork and ribs connected to each other.

Prior art

In general, in order to form a skeleton to be a skeleton of a reinforced concrete structure, such as building the frame, and the concrete is placed in this way, after the curing period, the frame is made by dismantling the formwork.

As such, the formwork used in forming a concrete structure generally has a structure in which a plurality of formwork panels are connected to each other using a coupling bolt.

In other words, as shown in FIG. 1, the formwork panel 100 includes a formwork 110 and ribs 120 provided on the rear surface of the formwork 110 to reinforce the bending strength of the formwork 110. And, the coupling bolt is a structure that is integrally fixed through the rib 120 of the formwork panel 100 to be interconnected.

As such, the structure for connecting and fixing the formwork panel 100 integrally using the coupling bolts must be fastened by using nuts after inserting the respective coupling bolts into the coupling holes provided in the ribs 120. There is a problem that the time is considerably longer and consequently the air is extended.

In addition, even when separating and disassembling the formwork assembled for the subsequent process after pouring and curing the concrete to each formwork panel 100, there is a problem that you need to loosen one nut fastened to each coupling bolt as described above The sex is significantly lowered.

In order to solve this problem, an assembly method using the wedge pin and the lock pin shown in FIG. 1 is also attempted. However, the lock pin is frequently lost, and the lock pin coupled to the wedge pin is separated one by one. There is a limit to improving workability because work is required.

 Therefore, there is an urgent need for the introduction of formwork fittings that are integrally formed and can be assembled and dismantled in a one-touch manner without fear of loss.

The present invention created to solve the above problems work by providing a formwork connector that can easily perform the work of connecting and fixing each other formwork panel and the assembled formwork to separate and dismantle the formwork to each formwork panel. The aim is to shorten the air by dramatically improving the properties.

In addition, another object of the present invention is to provide a means for stably maintaining a fixed state of the formwork connector fastened.

The composition of the present invention created to achieve the above object is as follows.

The present invention is a formwork coupler for connecting and fixing the formwork panel consisting of a formwork and ribs, each of the pin-shaped insertion portion connecting through the two ribs provided on the edge of each of the interconnection formwork panel; A 'c' shaped fixing portion for receiving two ribs provided on each rim of the formwork panel connected to each other and integrally fixing the ribs; And a connecting piece extending laterally from the rear end of the insert and integrally coupled with the fixing part, wherein the fixing part is integrally coupled with the connecting piece while the insert is inserted into two ribs. Rotating in the rib direction is characterized in that the two adjacent ribs are accommodated and fixed inside the fixed portion of the '' 'shape.

Hereinafter, with reference to the accompanying drawings, a specific embodiment of the present invention will be described in detail.

Figure 2 as a specific embodiment of the present invention, the formwork coupler 200 consisting of an insertion portion 210, a fixing portion 220, and a connecting piece 230 connecting the insertion portion 210 and the fixing portion 220 as one. )

Insertion portion 210 is configured in the form of a pin passing through two adjacent ribs 120 as shown in FIG.

The fixing part 220 is formed in a 'c' shape as a whole, and forms an integral part with the insertion part 210 by a connection piece 230 extending laterally from the rear end of the insertion part 210.

As described above, two adjacent ribs 120 are accommodated in the '220'-shaped fixing part 220.

FIG. 3 illustrates a process of connecting the formwork panel 100 into one by using the formwork coupler 200 shown in FIG. 2.

The insertion part 210 is inserted into the coupling hole provided in each of two adjacent ribs 120, and the fixing part 220 which is integral with the insertion part 210 by the connection piece 230 is rib 120 When rotated in the direction of), two ribs 120 adjacent to the inside of the 'c'-shaped fixing part 220 are accommodated to maintain a combined state.

When the assembled formwork 100 is to be separated and dismantled into each formwork panel 100, the work may be performed in the reverse order to that shown in FIG.

That is, when the fixing part 220 is rotated in a direction away from the rib 120 to separate the fixing part 220 and the rib 120 accommodated therein, the fixing part 220 and the rib 120 are in an engaged state. In this state, the insertion portion 210 may be removed from the coupling hole of the rib 120.

4 shows another specific embodiment of the present invention.

As shown in Figure 4, the insertion portion 210 has a ball 211 that is elastically supported by the spring at the front end is built.

Some of these balls 211 protrude to the outer circumferential surface of the insertion portion 210.

Therefore, in the process of inserting the insertion portion 210 into the coupling hole of the rib 120, the ball 211 is brought into contact with the inner surface of the coupling hole and retracted into the insertion portion 210, and after passing through the coupling hole, the spring As a result, the original state (the state protruding from the outer circumferential surface of the insertion portion 210) is restored to serve to prevent the insertion portion 210 from being easily separated from the coupling hole of the rib 120.

In addition, a separate elastic piece 221 is provided on the inner surface of the fixing part 220 so as to elastically support the received rib 120.

That is, the elastic piece 221 is provided on the inner surface of the 'c'-shaped fixing part 220 to elastically support the received rib 120 to prevent the fixing part 220 from rotating arbitrarily.

According to the present invention of the above-described structure ribs fixed portion to accommodate the ribs coupled to the inside of the fixing portion in the state in which the insertion portion of the formwork connector is inserted into the coupling hole provided in the rib of each formwork panel to connect the formwork panel with each other It is enough to perform only the operation to rotate in the direction, in order to separate and disassemble the assembled formwork to each formwork panel, it is sufficient to proceed in the reverse order, assembling and disassembly compared to the method using a conventional coupling bolt or wedge pin. It can reduce the air by drastically reducing work time and improving workability.

In addition, it is possible to stably maintain the fixed state of the formwork connector fastened using the ball provided at the front end of the insertion portion and the elastic piece provided on the inner side of the fixing portion.

In addition, when the formwork panel 100 is installed in the vertical direction, as shown in Figure 3, the fixing portion 220 is positioned vertically in the state in which the fastening of the formwork coupler 200 is completed to serve as a kind of weight. It is possible to maintain the fastening state more stably.
