Description

Formwork fixtures {fixed structure for form}

The present invention relates to a form fastener, and more particularly to a form fastener for fixing the gangform, euro foam formwork at a constant interval and more firmly at the time of wall construction of villas, apartments, buildings and the like.

In general, in order to build a wall during construction, formwork (Euro-foam, gang-form) formwork filled with raycons is formed to face each other, and the formwork is fixed so that the formwork is mutually supported and fixed inside the formwork. The walls were constructed by pouring concrete.

As shown in FIG. 4, the conventional concrete formwork fixture is sepatie (3) which is fitted between the euroform formwork (1) and the gangform formwork (2) and is fixed to the sepatie (3) and formwork fixing part (5) And a cone (4) having a spiral shaft (8) extending to one side to the formwork part (5), and a washer (6) coupled to the spiral shaft (8) to fix the gang formwork (1). And nut (7).

However, depending on the position of the Sepha Tie 3 and the cone 4, there is a problem that it is difficult to maintain a constant distance between the flow path, the gang form dies (1, 2), depending on the tightening force of the nut (7).

For example, if the nut 7 is loosely tightened in the process of fixing the Sepha Tie 3 and the cone 4, the nut 7 is separated by vibration and external impact, and the flow path and gang form dies when concrete is poured (1, 2). There was a problem that it is difficult to maintain a constant interval of).

In addition, if the nut 7 is tightened too much in the process of fixing the Sepha Tie 3 and the cone 4, a part of the gang form die 2 is pushed inward, so that the walls are not formed straight or horizontally. there was.

The present invention for solving the above problems is to provide a formwork fixed to the spring between the gang form dies and the cone, so that the flow path, the gang form dies have a certain distance.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing the present invention die fixing device, the present invention has a sephaty 30 fixed to the euro-foam formwork 10, and a form fixing part 41 is coupled to one side end of the theta pie 30; A spiral shaft 44 is formed extending to one side of the form fixing part 41 and includes a cone 40 installed in the gang form die 20, and the fixing shaft so that the spring 45 is interposed on the spiral shaft 44. It consists of 46.

The form fixing part 41 has a locking jaw 42 is formed at one end and extends in the same line on both sides, and a fixed shaft 43 and a spiral shaft 44 having screws on the outer circumferential surface are integrally formed.

The fixed shaft 43 is screwed to one side end of the Sepha Tie (30).

A spring 45 is fitted to the spiral shaft 44, and a fixing plate 46 is provided at one side of the spring 45.

The fixing plate 46 may be made of metal, plastic, or synthetic resin. The fixing plate 46 may have a “[“] shape, and the through hole 48 may be formed at the center thereof, and the through hole 48 may be moved forward and backward on the spiral shaft 44. Possibly combined.

2, 3 is a cross-sectional view showing a state in which the die fixture of the present invention is fixed or detached, the Sepha Tie 30 and the cone 40 is coupled to the flow-form, gang-form formwork (10, 20), the formwork fixing part ( 41) and the spring 45 is held on the line of the spiral shaft 44, and the fixing plate 46 and the nut 47 are installed on one side of the spring 45, and the fixing plate 46 is advanced and rotated a predetermined length. When the spring 45 and the fixing plate 46 is coupled to the support frame 21 of the gang form die 20, the locking jaw 42 of the form fixing portion 41 by the elasticity of the spring 45 is The gang foam dies 20 are in close contact with and fixed to each other, so that the flow-foam and gang foam dies 10 and 20 have a predetermined interval.

And tightening the nut 47 to the fixing bracket 22 of the support frame 21 is fixed in a more solid state.

In this way, by fixing the formwork fixing portion 41 by the elastic force of the spring 45, the interval between the flow path, the gangform formwork (10, 20) is kept constant.

In addition, it can sufficiently withstand the pressure applied to the gang foam, euro foam formwork (10, 20) during concrete pouring.

On the other hand, after generating concrete, first loosen the nut 47 fixed to the support frame 21 and rotate the fixing plate 46 to move away from the support frame 21, the elasticity of the spring 45 is released Subsequently, the Sepatie 30 and the cone 40 may be separated from the flow path and gang form dies 10 and 20.

Between the form fixing part 41 and the gang form die 20, the spring 45 is rotated back and forth, the fixed plate 46, which is burnt, the assembly of the euro form, gang form dies (10, 20) and detachment work is made easily.

And the cone 40 is separated from the flow path, gang form dies (10, 20) has the advantage that can be used.

The present invention is not limited to the above-described embodiments, and those skilled in the art to which the present invention pertains without departing from the gist will have the technical spirit of the present invention to the extent that various modifications can be made.

As described above, the present invention has the effect of being able to withstand the pressure generated at the time of placing concrete while at the same time maintaining the constant spacing between the flow form and the gang form dies by holding the spring on the cone.
