なお、この連結金具Ｂを金属材２，２から取りは
ずすときは、逆の手順をとればよい。 To attach the connecting fittings B to the metal materials 2, 2, place the metal materials 2, 2 of the formwork A adjacent to each other so that the lever insertion holes formed in the metal materials 2, 2 are aligned with each other. The clamping member 31 of the connecting fitting B
The lever 33 is inserted into the hole 32 and the lever insertion hole, and then the tip 33d of the lever 33 is bent in the length direction of the metal material 2, and the lever 33 is inserted into the hole 32 and the lever insertion hole. As shown in the figure, the distal end portion 33d may be rotated upward approximately 90 degrees to be locked in the locking gap 34a. In this case, the base 33b of the lever 33 is set to be slightly shorter than the width W of the opening of the clamping member 31, and since the protruding edge 32a is formed around the hole 32, the base 33b of the lever 33 is When the tip 33d is bent in the length direction of the metal material 2, the bent portion 33f of the tip 33d comes into contact with the convex edge 32a, and the tip 3
The bending angle between 3d and the base 33b is slightly larger than 90°. (Figure 10). In this state, if the tip 33d of the lever 33 is pressed against the metal material 2 side and rotated upward to be locked in the locking gap 34a, the bent portion 33f of the tip 33d will be moved to the convex edge 32a of the hole 32. The bent portion 33f and the head 33a are pressed together.
Since the metal members 2, 2 are tightened from both sides of the connecting fitting B, that is, the metal members 2, 2 are tightened from the sides, the formworks A can be firmly and easily connected to each other.
Incidentally, when removing this connecting fitting B from the metal materials 2, 2, the procedure may be reversed.

It is configured to include a support member 53 through which a thick end material 52 for fixing the formwork A is inserted and supported. The clamping member 51 has a pair of flat plates 54, 54 which are arranged opposite to each other in parallel to sandwich the auxiliary metal material 4, and bolt insertion holes 55, 55 facing each other are provided in the middle of the flat plates 54, 54. Furthermore, this flat plate 5
4 and 54 are formed with bent portions 56 and 56 that are slightly bent in a direction that separates them from each other so that they can be easily fitted to the auxiliary metal material 4. Further, the support member 53 has an insertion portion 57 formed by bending a single band-shaped plate into a U-shape, and both ends of the insertion portion 57 are bent outward at right angles. Connecting part 5

The bolt insertion holes 55, 55 of 1 are aligned, and the bolt 60 is inserted and fastened. Next, a thick end material 52 that prevents deformation such as warping or bending of the formwork A is inserted into the insertion portion 57 of the support fitting C and fixed with home ties (registered trademark) 61. At this time, since one side surface of the auxiliary metal material 4 is exposed to the opening 59 of the support metal C, the side surface of the end thick material 52 directly abuts this exposed surface, that is, one side surface of the auxiliary metal material 4. , thus preventing the entire assembled formwork A from warping or bending. Formwork A is assembled in this way, and then concrete is poured and construction is carried out.
Next, when constructing the next floor, after removing the home ties 61 of the assembled formwork A, the entire formwork is moved. At this time, since the thick end material 52 is inserted into the insertion part 57 of the support fitting C and is supported by the insertion part 57, even when the entire formwork is moved, To prevent the formwork A from warping or from partially shifting.

きる。 Further, FIGS. 15 and 16 show other modified examples of the support fitting C'', and the feature of this support fitting C'' is that the thick material 52 can be fixed to the auxiliary metal material 4.
This support fitting C″ includes a U-shaped support body 70,
It consists of an auxiliary plate 71 attached to the upper part of the support body 70 and a pressing plate 73 to which a stop plate 72 is welded. The upper part of the support body 70 has a screw hole 70a into which a thumb screw 74 is inserted, and the slits 70b into which both ends of the press plate 73 are slidably inserted are formed on both sides, and the auxiliary metal material 4 is inserted into both ends. A locking portion 70c and a fixing portion 70d that lock into the groove 4a are respectively formed. The method of attaching this support fitting C″ to the auxiliary metal material 4 is almost the same as the support fitting C′ of the above-mentioned modification, but this support fitting
C'', by pressing down the press plate 73 with the nut 74a fixed to the lower end of the thumbscrew 74, the end material 52 inserted between the press plate 73 and the auxiliary metal material 4 is assisted. It can be fixed to the metal material 4.

もある。 The formwork device of the present invention has the above-mentioned structure, and the upper, lower, left and right metal members 2 and 3 are arranged such that the end face b of the metal member 2 is brought into contact with the projecting piece a of the metal member 3, and the inner face d of the metal member 2 is brought into contact with the protruding piece a of the metal member 3. While bringing the end surface c of the metal material 3 into contact with each other, screw the screw 19 into the circular groove 13 of the metal material 2 through the small hole i of the protruding piece a, and insert the metal material through the small hole j in the inner surface d of the metal material 2. Since the screws 20 are screwed into the circular grooves 12 of 3 and assembled together, the assembly strength is strong.Furthermore, unlike conventional formwork, auxiliary fittings are not required, so assembly is easy and large quantities can be produced. It has the advantage of being easy to produce and having low manufacturing costs. In addition, since a sealing material 6 is installed on the outer peripheral surface, the joint surface between two adjacent formworks connected horizontally or vertically has good liquid tightness, and concrete flows and hardens in this area. The formwork is easy to remove. Furthermore, since the plate material 5 is attached to the frame 1 by being fitted into the fixing part 10 surrounded by the upright edge 8, the fixing force of the plate material 5 to the frame body 1 is strong, and the plate material 5 is attached to the upright edge 8. Since the metal members 2 and 3 are provided with inner edges 9 and the plate member 5 is supported by a wide surface, damage to the side portions is suppressed as much as possible. The fixing force of the plate material is further strengthened, and the cross-sectional shape of the metal materials 2 and 3 can be made smaller, which has the advantage of reducing weight and cost.
