The reinforcing rib 130 has a second coupling part 131 protruding to one side of the plate surface is inserted in the first axial direction to the first coupling part 115 formed on the rear surface of the finishing panel 111, the second coupling part Since 131 is interposed between the finishing panel 111 and the locking jaw portion, the third axial position of the reinforcing rib 130 is fixed. The reinforcing bar 140 is inserted through the insertion holes 113 and 132 formed in the first flange 112 and the reinforcing rib 130 of the main frame 110, respectively, to increase rigidity against bending or torsion of the formwork panel. You can.

A plurality of such reinforcement ribs 130 are provided and positioned at positions where the reinforcement bars 140 are disposed, respectively, thereby forming the formwork panel 130 unnecessarily by forming the reinforcement ribs 130 at a portion where the reinforcement bars 140 are not disposed. The weight of can be prevented from increasing.

The reinforcement bar 140 is in a state in which the insertion protrusions 141 of the reinforcement bar 140 and the

insertion grooves

In addition, since the through hole 142 formed in the center of the reinforcing bar 140 is formed in a square shape, the reinforcing bar 140 can be easily axially rotated using a tool having a protrusion corresponding to the square through hole 142. The groove 143 formed on the outer circumferential surface of the reinforcement bar 140 may form a plurality of corners on the outer circumferential surface of the reinforcement bar 140, so that the reinforcement bar 140 may be arbitrarily rotated in the insertion holes 113 and 132. You can prevent it. In addition, the weight of the reinforcing bar 140 can be reduced by the through-hole 142 and the recess 143 formed in the center of the reinforcing bar 140, thereby minimizing the material cost and the load of the formwork.

On the other hand, the reinforcement bar 140 is inserted into the insertion hole 113 of the first flange portion 112 of the main frame 110 and the insertion hole 132 of the reinforcing rib 130, the assembly is completed, the reinforcement By plastically deforming both ends of the bar 140, it is also possible to prevent the reinforcing bar 140 from being separated from the main frame 110.
