Description

System Supporter {The System Supporter}

The present invention relates to a system support, and more particularly, to supporting a concrete structure (including a formwork), it is easy to fasten a vertical rod and a horizontal rod, and in the case of a vertical rod, To a system support capable of stably supporting a concrete structure.

Conventionally, in general, a mold is used to provide a concrete installation space for constructing a concrete structure. The mold is supported by a single support, and the operation of connecting the single support to the multi-stage is difficult. In general, the ceiling of each floor of the building has a uniform height, and thus the support of the ready- .

Especially, in the case of concrete steel structure, the concrete structure should be supported until the completion of curing after the concrete is laid. At this time, a supporter is installed from the ground to support the work footrest and the concrete structure.

As a conventional supporter related to such a technique, there has been found a registration utility model No. 20-0393432 (Patent Document 1). However, in the technique of Patent Document 1, the quantity to be used is determined according to the size of the concrete load, And therefore, it is inevitable to use a large amount of water and has a limitation in achieving stable support.

Even if the support pipe connecting the outer pipe and the inner pipe with the coupling portion is secured, the coupling portion is deformed flexibly due to the high load, and there is a fear that the shape is collapsed due to the breakage of the coupling portion.

Also, as a conventional technique, a technique disclosed in Japanese Utility Model Registration No. 20-0288392 (Patent Document 2) has been proposed, but the above problems are still insufficient to overcome.

In order to solve the above problems, a support has been proposed in which a plurality of pipes are combined and fixed to secure a large supporting force against a load.

In the conventional support, a plurality of pipes are manufactured to have a predetermined length through a plurality of fixing pieces. However, the pipes are welded to each other, which is a disadvantage that they are used for disposable use.

In addition, it is difficult to fix the joints between pipes, which makes it difficult to install and dismantle quickly due to the troublesome and inconvenient operation for supporting concrete structures and demolishing after concrete curing, which limits the stability of the entire concrete structure.

7, it has been described that the clamping angle adjuster 32 surrounds the clamping unit 31 from the outside. However, in the structure in which the clamping unit 31 is connected to the vertical rod 10, The control member may be constructed such that the control member is extended from the inside of the clamping unit and the clamping unit is coupled to the vertical bar. 10 and 11, the clamping unit 31 includes a clamping frame 31-1 and a pair of clamping members 31-2 connected to the clamping frame 31-1. The sphere 32 is moved forward and backward between the pair of tongues 31-2 so that the tip ends of the pair of tongues 31-2 are gathered to clamp the vertical rod 10 or the pair of tongues 31-2 So that the distal end portion is opened to unclamp the vertical bar 10.

More specifically, the clamping frame 31-1 is a frame for fixing the pair of clamps 31-2 and can be fixed to the screw rod 33 by various methods (fitting, screwing, etc.).

The center of the tongue 31-2 is connected to the clamping frame 31-1 between the opposite ends of the clamping member 31. The tip of the clamping member 32 is moved forward by the clamping angle adjusting member 32, That is, connected in a seesaw form through hinge pins 31-3 or the like.

Here, all of the pair of clamps 31-2 may be connected to the hinge pin 31-3, or one of the clamps 31-2 may be fixed and the other clamp 31-2 may be hinge- .

In addition, the portion to which the hinge pin 31-3 is connected is not limited to a circular hole, and may be a long hole. Of course, all of the pair of clamps 31-2 may be connected to the clamping frame 31-1 through a long hole, or may be connected through a combination of a long hole and a right hole. In the case of the long hole, the tongue 31-2 can be moved and the tongue 31-2 can be easily connected to and disconnected from the vertical bar 10. Although the elongated hole 31-4 is shown as being formed on the tongue 31-2, the elongated hole may be formed on the tongue die 31-1.

The clamping angle adjusting member 32 is connected to the screw rod 33 so as to be movable forward and backward. The clamping adjusting member 35 is moved forward by tightening the clamping member 35 and the tip ends of the pair of clamping members 31 - Clamp it. The fork angle adjuster 32 may be integrally formed on the front side of the washer 34 or may be a separate single piece.

The front end of the tongue 31-2 is tilted toward the tongue 10a of the vertical bar 10 so that the rear of the tongue 31-2 is naturally opened by the advancement of the tongue angle adjusting member 32 31-2 and the tongue angle regulating opening 32, respectively.

12 and 13, the pair of clamps 31-2 are arranged in the vertical direction so as to be perpendicular to the vertical portion 10a of the vertical bar 10, The periphery of the rod 10 may be wrapped and clamped. That is, the present invention is applicable not only to the vertical bar 10 having the protruding portion 10a but also to all vertical bars such as a circular pipe and a square pipe. In addition, the manner in which the clamp 31-2 clamps the vertical bar 10 is not limited to the clamp shown in Figs. 10 to 13 but is applicable to all the clamps described above.

As shown in Fig. 14, the elastic member 31-5 is applied so that the pair of clamps 31-2 can be opened and fastened more quickly. The elastic member 31-5 can be used as a coil spring or a leaf spring and is interposed between the clamp frame 31-1 (or the screw rod 33) and the pair of clamps 31-2, (Clamping portion) of the clamping portion 31-2.

15A and 15B, the clamping frame 31-1 may be rotatably connected to the screw rod 33 via the hinge 31-6, and the clamping frame 31-1 So that the pivoting width of the pliers 31-2 is increased, so that it is very easy to engage and separate the pliers 31-2.

In addition, although only one screw rod 33 is shown, two screw rods 33 may be connected to each other through a connecting nut so as to be used in various lengths.

16 and 17 show another example of the horizontal bar to which the present invention is applied, in which truss type transverse steel 100 is applied. The truss-like transverse steel 100 includes two or more first and second transverse strips 110 and 120 arranged in the transverse direction (two transverse stripes are shown as examples), two or more transverse strips 110 and 120 connecting the first and second transverse strips 110 and 120, A vertical connecting rod 130, and at least one inclined reinforcing bar 140.
