The present invention relates to a clamp, and more particularly, to a die frame binding clamp that can be easily and firmly bonded to the form borders of various sizes than conventional binding holes (clamps, pins, bolts).

And, the present invention is to facilitate the operation of the wedge irrespective of the direction of the formwork frame of different sizes.

As is well known, formwork frames must be installed in advance for concrete pouring during construction and civil works.

Installation of the formwork frame is usually installed scaffolding in the frame, and the worker climbs on it to work individually, in which case the worker connects the formwork made of wood using screws or nails, formwork frame for concrete placement The panel will be installed.

On the other hand, in recent years, the standard formwork frame has been proposed to facilitate the above-mentioned formwork frame work.

The formwork frame is provided by providing a standardized panel of different sizes and attaching a profile (a profile for supporting formwork formwork) and aluminum form steel to one side of the panel.

As a conventional method of connecting the standard formwork frame, a method of connecting a hole through the profile and the aluminum section steel using fastening elements such as pins (wedge pin, alfoam pin, etc.), bolts, nails, and rivets is used. have.

However, the conventional fastening method is accompanied by a problem that the work is cumbersome and damages the formwork frame.

More specifically, conventional fastening methods require drilling holes in profiles and aluminum sections to use pins (wedge pins, alfoam pins, etc.), bolts, nails, rivets, and time and expense for such drilling operations. There is a problem that the strength of the profile and the aluminum shaped steel, that is, the member is lowered.

In addition, the conventional fastening method takes a lot of time because the screw must be loosened during the dismantling of the formwork rim, there is an inconvenience in that the rivet should be removed by cutting the head.

In order to solve such a problem, the clamp has been proposed in the Republic of Korea Open Utility Model No. 194-8002.

The clamp according to the prior art has a first pressing piece for pressing the coupling object (in the present invention, taking the formwork frame as an example, that is, the coupling object means two formwork frame), and the wedge on the body A base member having a ball formed therein; A guide slide slides into the body of the base member and has a base having a first diameter formed thereon, and a second pressing piece for pressing the first and second die edges on the opposite side opposite to the first pressing piece. A slider member; It holds between the first diameter and the second diameter coupled to the tooth, and is composed of a wedge for moving the slide member in a direction perpendicular to the traveling direction as penetrated through the wedge.

 According to the clamp according to the prior art, it is possible to perform the joining work of the members without additional processing to the first and second die frame, the first and second die frame can be easily combined and dismantled work, Since the distance between the first and second pressing pieces can be adjusted, there is an advantage that can be easily tightened regardless of the size or type of the first and second die frame, there are the following problems.

As shown in FIG. 1, although the first and second die borders 1 and 2 form one die border, their sizes are different so that the positions where the first and second pressing pieces 3 and 4 are caught and fixed may be different. Since the first and second pressing pieces 3 and 4 of the base member 5 and the slider member 6 are structured in the same size, the clamp member of the base member 5 and the slider member 6 cannot be coupled to each other. have.

On the other hand, as shown in Figure 2, the length of the base member 5 and the slider member 6 may be configured differently.

According to such a conventional clamp, when the first and second die frame (1, 2) is arranged as shown in Figure 3a, as shown in Figure 3b, the wedge (7) is fastened from the top, as shown in Figure 4a the first and second die frame When (1, 2) is arranged, the left and right sides of the clamp are coupled to the first and second die frame (1, 2), and as shown in Figure 4b, the wedge 7 is coupled from the bottom to the top.

That is, when the size of the first and second die frame (1, 2) is different, there is a disadvantage in that workability is inferior because it is very inconvenient to fasten the wedge (7) from the bottom to the top when installing the left and right of the clamp, When concrete is poured, it may be dismantled by a pour impact, and there is a risk that the worker is dismantled even by a weak impact applied by the body or consumables while the worker is moving.

The present invention is to solve the problems as described above, each formwork frame when the formwork can not catch the formwork border using two different formwork size or type of the coupling object or the locking jaw basically equipped in the clamp It is an object of the present invention to provide a die frame binding clamp that enables the die frame to be bound by a simple operation without separately manufacturing a separate clamp.

In addition, another object of the present invention is that when the mold frame of the different size is installed in the left and right opposite direction to install the clamp divided into left and right types, it is convenient to make the clamp in one body on the left and right types I'm trying to make it.
