On the other hand, according to another embodiment of the separation prevention stopper 191 directly welds the bolt to one end of the elevating bolt 140, or by inserting a washer on one end of the elevating bolt 140 and welding it. Or the like.

However, in the case of maintenance work such as replacement of the lifting bolt 140 due to breakage of the screw thread formed on the outer circumferential surface of the lifting bolt 140, the dropping prevention stopper 191 lifts the bolt 140 by a method such as welding. This maintenance work can be inconvenient when combined in one piece. Therefore, in order to facilitate such maintenance work, the mold support 100 of the present embodiment further includes a maintenance hole 120a formed through the upper surface of the horizontal support 120.

The maintenance hole 120a is formed to penetrate the upper surface of the horizontal support part 120, so that the lifting bolt 140, to which the escape preventing stopper 191 is integrally coupled, may be easily drawn out from the horizontal support part 120. The configuration is provided, and is formed larger than the diameter of the separation prevention stopper 191.

In addition, when the size of the side panel 2 of the formwork 1 is large, the operator inserts the extension 193 into the interior space of the vertical support 110 to correspond to the size of the side panel (2). .

Next, the worker fits the first contact plate 163 of the first fixing part 160 and the second contact plate 173 of the second fixing part 170 to the lower side of the horizontal member (SB1), After the fitting operation is completed, the tightening nut 150 is rotated to allow the tightening nut 150 to move downward of the lifting bolt 140.

When the tightening nut 150 gradually moves to the lower side of the lifting bolt 140, the lower side of the tightening nut 150 comes into contact with the angle adjustment bracket 180, and then continues to tighten the tightening nut 150. 191 and the lifting bolt 140 gradually rise, and accordingly, the first fixing part 160 and the second fixing part 170 gradually pull the horizontal member SB1. That is, according to the tightening operation of the fastening nut 150, the first fixing part 160 and the second fixing part 170 respectively pull one lower end and the other side of the horizontal member SB1, and thus the horizontal support part 120. The horizontal support (SB1) is in close contact with the end) so that the mold support 100 is fixed to the horizontal member (SB1).

After the fixing operation is completed, it is possible to more firmly couple the mold support 100 and the horizontal member (SB1) by rotating the separation prevention stopper 191 and the tightening bolt 192 as necessary.

After fixing the pair of mold supports 100 to face each other along the horizontal member SB1, the concrete is poured and cured in the interior of the formwork 1, and after the curing is completed, the above-described coupling process is reversed. Proceeding to separate the mold support 100 from the horizontal member (SB1).

The mold support 100 according to the present invention includes a first fixing part 160 provided to omit a conventional tie bolt and a second fixing part 170 provided separately from the first fixing part 160. As a result, in the construction of the beam formwork (1), it can not only sufficiently resist the surface pressure applied when placing concrete, but also has the advantage of being easily installed and separated.
