Move in The left and right molds are slid to the upper predetermined positions by the slide mechanism of the body and the rear support, and the respective support members are extended upward and connected to the upper left and upper right of the lower frame. After that, the upper jacks of the respective support members finely adjust the heights of the left mold and the right mold to support them. Besides , after building the beam,
After reducing the supporting members removed from the upper left side and the upper right side of the lower frame downward, the left and right molds are returned to their original lower positions by the slide mechanism of the front and rear supports. Slide it. Therefore, during and after the construction of the beam, the left and right molds are simply slid vertically by the slide mechanism of the front support and the rear support without any external mechanical force being required. It may be one layer quickly and safely assembled and disassembled with a necessary minimum force.

[0022] Besides, the slide mechanism of the front support and rear support, the left guide rail of the lower portion and between the right guide facing each front-rear direction of the front support and the rear support of the lower frame Between the rails, an interlocking rod with an operating piece for mounting the slide handle protruding from one end is installed so that the bevel gear is rotatably supported on one inner side surface of each left guide rail and each right guide rail. Each left guide rail and each right guide rail has a threaded rod with a small bevel gear at its lower end that meshes with the large bevel gear of the interlocking rod inside the left and right guide rails. The screw rods are rotatably supported so as to be interlocked with each other, and the inner ends of the pulling members of the left and right molds are attached to the respective left and right guide rails. A pair of guide rows Since the openings are connected to each other through the openings, by attaching and turning the slide handle to the operation piece at one end of the interlocking rod of the slide mechanism, the left guide rails and the right guide rails can be constructed during and after the construction of the beam. Each screw rod inside the rail rotates from the interlocking rod via the large bevel gear and the small bevel gear, respectively, and accordingly, the inner ends of the screw rods are connected to the left and right formwork, respectively. each Obiki material, for sliding in the vertical direction via a pair of guide rollers of each left guide rails and in each right guide rails, it is possible to first layer quickly and safely assembled and disassembled with a necessary minimum force .
