The distance between the long wedge insertion holes 32a, 32a penetrating through the plate pieces 32b, 32b provided integrally with the bent portions 31, 31, of the metal fitting 1, is set to the wedge driving long holes B1, B1 of the stay rod B. The wedge insertion slot of the reinforcing metal fitting 1 is adjusted so as to match the interval between them.
32a, 32a are inserted into the long holes B1, B1 for wedge driving of the stay rod B.
Lay on top. At this time, the plate piece 32b of the reinforcing bracket 1
, 32b are inserted into the through holes E1 of the contact plate E, and the inner surfaces of the distal ends of the long holes 32a, 32a of the reinforcing metal fitting 1 are positioned closer to the mold A than the contact plate E. It has been adjusted to: The wedge insertion slot 32 of the reinforcing bracket 1
Through a, a wedge F is driven from above into the wedge driving slot B1 of the stay rod B, and the formwork A is firmly joined at a desired angle (see FIG. 5).

楔Fの打ち込み作業に影響を及ぼすことはない。The stay rod B has an elongated hole for driving a wedge.
As the wedge F is driven into B1, the plate F is displaced toward the mold A and the wedge F is also driven deeper into the mold A, but the stay rod B has a long hole for driving the wedge.
A slot 32a for inserting a wedge of the reinforcing fitting 1 superimposed on B1
Is longer in the direction perpendicular to the outer surface of the mold A, and the length direction of the wedge driving slot B1 of the stay rod B matches the length direction of the wedge insertion slot 32a of the reinforcing metal fitting 1. In addition, as described above, the elongated wedge insertion holes 32a of the reinforcing metal fitting 1
Since the inner surface of the tip of 32a is adjusted so as to be located closer to the mold frame A than the aforesaid plate E, the slot 32a for inserting the wedge of the reinforcing metal fitting 1 has the slot for inserting the wedge of the stay rod B. It does not affect the operation of driving the wedge F into B1.

殆ど影響を及ぼすことなく確実に行うことができる。The direction in which the vertical and horizontal fluttering members C and D are tightened by driving the wedge F into the wedge driving slot B1 of the stay rod B is determined by the wedge insertion slot 32a of the reinforcing bracket 1 and When the wedge F is driven into the long wedge driving hole B1 of the stay rod B, the wedge F is aligned with the lengthwise direction of the wedge driving long hole B1 of the stay rod B. Since no force is applied to the inner surface of the elongated hole 32a for inserting the wedge of the reinforcing member 1 and the inner surface of the elongated hole B1 for driving the stay rod B, the reinforcing member 1 and the stay rod B are bent. The wedge F can be smoothly driven into the wedge driving long hole B1 of the stay rod B without exerting an excessive force in the direction, and the fixing operation by the reinforcing bracket 1 has almost no influence on the stay rod B. Without fail.

することができる。According to the present invention, there is provided a reinforcing metal fitting for a corner of a formwork provided along the outer surface of a corner of a formwork joined to each other to reinforce the joint between the two forms. The left and right screw portions formed at the inner ends of the left and right arm members are screwed into a cylindrical body having left and right screw nut portions provided at both ends, respectively. The outer end of the arm member is bent in the same direction to form a bent portion, and a wide plate piece is integrally provided in both bending portions in the bending direction. Since the long wedge insertion long hole is formed so as to penetrate in the orthogonal direction, the interval between the wedge insertion long holes of the left and right arm members is joined by rotating the cylinder. Between the long holes for wedge driving penetrating the tip of the stay rod protruding from each outer surface of the formwork After matching the gap, the left and right arm member wedge insertion slots are overlapped with the wedge driving slots of the stay rod, and a wedge is driven into the wedge driving slots from above. A series of operations such as firmly fixing and rotating the cylindrical body to reduce the interval between the wedge insertion slots can reinforce the joined state of the joined formwork.

The acting force of the wedge always acts in the longitudinal direction of the wedge driving slot and the wedge insertion slot, so that an excessive stress in the direction of deforming the reinforcing bracket or the stay rod is applied to the reinforcing bracket or the stay rod. The wedge can be driven smoothly without generation, and an accurate and strong mold joining structure can be obtained.
