The structure of the slide guide plate 7 is structured such that it can slide freely, and a punched portion 12 is formed at the wedge-shaped wide side end of the slide guide plate 7. With this structure, the above object can be achieved. It's arrived.

An embodiment of the present invention will be described in detail below with reference to the drawings.

As shown in FIG. 4, the formwork 1 has a pair of vertical ribs 13 and a pair of horizontal ribs 14 as side plates 2 as four side walls, and a face plate 15 is held by these side walls. Connection holes 4 are provided in each of the vertical ribs 13 and the horizontal ribs 17 at a constant pitch. Further, a middle vertical rib 16 and a middle horizontal rib 17 are provided for reinforcement.

All members of such a formwork 1 are made of metal plates such as iron plates. The formwork 1; 1 is designed so that the formwork connection A shown in FIG. 11 can be connected.

Formwork connection A will be explained below. Formwork connection A is fixed body 1
8 and a moving body 19. The fixed body 18 and the movable body 19 are each provided with clamping plates 3; 3 capable of clamping the side plates 2; 2 of the formwork 1; 1. Then, among the pair of clamping plates 3; 3, which are opposed to each other in substantially parallel with an interval large enough to sandwich the two adjacent side plates 2; 2 of the adjacent formwork 1; 1, the fixed body A connecting protrusion 5 that can be inserted into the connecting hole 4 provided in the side plate 2 on the opposite side of the holding plate 3 of No. 18 and has a height lower than the thickness of the side plate 2.
This is provided. A fixed guide plate 6 is provided substantially orthogonally to the clamping plate 3 of the fixed body 18. The slide guide plate 7 that can be slid by the fixed guide plate 6 is moved to the movable body 19.
It is provided substantially perpendicularly to the clamping plate 3 of. Fixed guide plate 6
A bin with a head 8 is provided. The slide guide plate 7 is provided with a long hole 9 through which the headed bottle 8 can be slidably guided. The elongated hole 9 is inclined with respect to the holding plate 3. At the tip of the fixed guide plate 6, there is a hole approximately parallel to the elongated hole 9.
It is provided by bending the side piece 10.

The leading edge 11 of the slide guide plate 7 is substantially parallel to the elongated hole 9, and the slide guide plate 7 is formed into a wedge shape. A striking portion 12 is formed at the wedge-shaped wide side end of the slide guide plate 7. Then, the headed bottle 8 of the fixed body 18 is moved to the movable body 1.
The formwork connector A is inserted into the elongated hole 9 of 9 in a manner that it cannot be pulled out and is slidable. The headed pin 8 is made by inserting the narrow diameter part 21 of the rivet 20 through the long hole 9 and the caulking hole 23 of the fixed guide plate 6 through the washer 22, and expanding the diameter of the tip of the narrow diameter part 21 so that it cannot be removed. However, various configurations can be considered, such as using bolts and nuts, and various design changes are possible. Alternatively, the long holes 9 may be provided in the fixed guide plate 6 and the headed pins 8 may be provided in the slide guide plate 7.

According to such a configuration, the two adjacent side plates 2 of the adjacent formworks 1 are positioned between the clamping plates 3 of the fixed body 18 and the movable body, and the fixed body 18 is The connecting protrusion 5 is inserted into the connecting hole 4 of the side plate 2 of 11, and the movable body 19 is moved against the fixed body 18 by hitting the striking part 12 with a hammer or the like in the direction of the arrow shown in FIG. Slide it
The holding plate 2 of the movable body 19 is strongly pressed against the side plate 2 by the wedge effect, and the adjacent formworks 1; 1 are connected firmly without rattling. In such a case, the tip of the clamping plate 3 of the fixed body 18 is bent, and the welding point 24 between the face plate 15 and the side plate 2 is bent.
This is so that you can avoid it.

By making the height of the fixed body 18 substantially equal to the height of the side plate 2, the end surface 25 of the side plate 2 can be brought into contact with the fixed guide @6, and the tip of the clamping plate 3 can be stably attached to the face plate 15. It is good that it can be brought into contact with the Further, in such a case, the side plate 2 on the side of the movable body 19 does not have to be at the same level as the adjacent side plate 2, and the formworks 1; 1 can be connected at different levels.

[Effects of the Invention] In short, the present invention positions two adjacent side plates of adjacent formworks between a pair of clamping plates, and connects the connecting protrusion of one clamping plate to the connection hole of the side plate on this side. Insert the wedge-shaped slide guide plate provided on the other clamping plate against the fixed guide plate provided on one clamping plate, and slide the wedge-shaped slide guide plate provided on the other clamping plate by hitting the punched portion, and tilt the plate with respect to the clamping plate. By bringing the clamping plate on the side of the slide guide plate close to the clamping plate facing it through the elongated hole, the two side plates can be clamped and connected by a pair of clamping plates. This method has the advantage that there is no need to align the connection holes as described above, and the work of connecting the formwork can be performed simply and easily. Moreover, there is an advantage that a sturdy connection can be made without causing any rattling after connection due to the number of connections caused by driving the wedge-shaped slide guide plate. In addition, since the fastening structure inserts a connecting protrusion (with a height lower than the thickness of the side plate) into only the connection hole of one side plate, connection can be made without worrying about the position of the other side plate, and therefore one side plate can be connected without worrying about the position of the other side plate. There is an advantage in that the vertical height of the other side plate can be different from that of the other side plate, that is, the formwork can be connected at different levels.
