Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column clamp or a column clamp for supporting a formwork panel for forming a column of a building or the like.

[0002]

2. Description of the Related Art Forming a pillar of a building or the like requires a formwork panel and a flap or a square timber for supporting the formwork panel. Conventionally, in forming a pillar of a building or the like, the formwork panel of the pillar is surrounded by loose flakes or square timbers and fastened with wedges or the like.

[0003]

In order to form the columns, it was necessary to apply vibration with a vibrator in order to evenly fill the concrete in the form panel after pouring the concrete. Therefore, there is a problem that the wedges that are tightening the form panel are loosened.

Further, the flutter material and the square material for tightening and supporting the formwork panel are different from each other, and when assembling the individual members, the combination is troublesome depending on the size of the concrete columns and the like.

Further, since the members are disjointed, there is a problem that the members are easily lost during storage and transportation.

According to the present invention, a pillar formwork panel of a building or the like can be pressed from the outside as a set of units without using square timbers, flaps, or wedges, and fine adjustment can be extremely performed according to the thickness of the pillar. The aim is to obtain a column clamp that can be easily done.

[0007]

[Means for Solving the Problems] In order to achieve this purpose,
The present invention comprises two sets of corner forming frames which are foldable and whose corner forming positions are freely changeable. Two sets of corner forming frames consist of at least one column forming frame. The member proposes a column clamp, characterized in that a clamping member is provided at its end.

Further, it is composed of two sets of corner forming frames which are foldable and whose corner forming positions are freely changeable. Two sets of corner forming frames, one column forming member of each corner forming frame. Proposes a pillar clamp characterized in that a tightening member is provided at its end, and the other clamp is connected to the end of the columnar member of the other corner forming frame without the tightening member.

Further, it is composed of two sets of corner forming frames which are foldable and whose corner forming positions are freely changeable, and two sets of corner forming frames, one column forming member of each corner forming frame. Is provided with a tightening member at its end, and is connected to the end of the other corner forming frame that does not have a tightening member, and the tightening member can be tightened diagonally with respect to the other pillar member. We propose a column clamp that is a simple clamping member.

[0010]

In one set of corner forming frames, the corners are formed by adjusting the combined positions of the two columnar members to match the thickness of the column form. It is possible to match the inner length of the columnar member, that is, the thickness of the column, depending on the position where the corner is formed.

Further, the corners of each corner forming frame are positioned on a diagonal line, and by the tightening member of the columnar member,
Each is connected to the other columnar member. Then, the column formwork is further tightened by tightening the tightening member.

If this tightening member can be tightened diagonally with respect to the other columnar member, the corner can be tightened from the left and right of the corner of the tightening member.
