た状態となる。 Next, how to use the fastener will be explained. Stand up the weir plates A on both sides, insert the screws 26 at both ends of the separator 25 with terminals 28 into the through holes 29, and screw the screw holes 3 of the tightening rod 1 into the protruding parts of the screws 26 to connect the terminals 28 and the tightening rod. Weir plate A with tsuba 2 of 1
While holding the clamp, the presser feet 6 and 7 of the fastening fitting a are directed in the vertical direction. Thereafter, when the locking cam 20 is rotated about the shaft 24 and laid down as shown in FIG.
It rotates due to the elasticity of 4 and 15, and its inner part becomes open.

の間隔を所定に保持して型枠を構成する。 Next, as shown in Fig. 4, one corner of the horizontal flap material D is fitted into the recess 9 of the presser foot 7 of the fastening fitting a, and then the horizontal flap material D is inserted inside. If you lift it upward, the horizontal bar material D and several presser feet 7 will be removed.
resists the elasticity of the spring 15, pivots integrally with the pin 13 in the direction of the arrow in FIG.
As shown in the figure, the other flat part of the horizontal flap member D comes into contact with the vertical flap member B. Therefore, while holding the horizontal beam D in a lifted state, the locking cam 20 is rotated clockwise in FIG. 2 using the shaft rod 24 as a fulcrum from the above state to stand up as shown in FIG. 2. By the guiding action of the cam surfaces 21 and 22 of the locking cam 20, the upper and lower edges are joined to the contact surfaces 10 and 11 of the presser feet 6 and 7, and the locking cam 20 is fitted between the contact surfaces 10 and 11. This fixes the presser feet 6 and 7, and connects the terminal 28 and the presser foot 6,
7 and clamp the weir plate A and the vertical and horizontal flaps B, C, and D and tighten and fix them together.
The formwork is constructed by maintaining a predetermined spacing.

その手間を省き得る。 In the present invention, the concrete formwork clamping fitting is configured as described above, so when the locking cam is laid down, the upper and lower presser feet are opened at their base sides due to the elasticity of the spring, and their recesses are directed upward or downward. is maintained. Therefore, without operating the upper and lower presser feet in any way, the upper side piece fits into the recess of the upper presser foot of the clamping fitting from above and is pushed inward and downward, and the lower side piece is pushed downward. Simply fit into the recess of the lower presser foot of the clamping tool and lift it upward inwardly, then turn the locking cam to raise it up and fit it between the contact surfaces of the presser foot. It is possible to fix a pair of horizontal beams and install them vertically in parallel, which eliminates the need to connect or disassemble the horizontal beams used in a pair with several fasteners, as in the past. Since there is no such thing, that effort can be saved.

向上する。 Furthermore, by immediately fitting the cross-piece into the recesses of the presser feet of several clamping fittings and moving it in the direction of the clamping rod, the presser foot of several clamping metal fittings can be flattened. The horizontal material can be installed by rotating integrally with the material, and after that, all you need to do is turn the locking cam, so the upper and lower presser feet of the tightening tool do not need to be operated at all due to the elastic pressure from the spring. In addition, since the locking cam only needs to be rotated, it is extremely easy to fix and release the upper and lower pressers using the locking cam, and the formwork can be assembled and dismantled easily and quickly. , and the locking position of the horizontal beams is always constant without tightening the upper and lower clamping fittings, so the horizontal beams are in even contact with the vertical beams over the entire surface of the formwork, and the formwork is not tightened like in the past. There is no deformation of the weir plate due to over-tightening or uneven tightening. Therefore, even if you are not a skilled craftsman, you can always tighten and fix the formwork evenly and form the concrete surface with high precision, improving work efficiency.
その上、構造が簡単で容易安価に製作し得ら
