As explained above, according to the reinforced concrete floor formwork supporting material assembly hardware according to the present invention, the square pipe 2 as a large lumber
Since it supplements the length of , and is expandable and contractible, the length L' of the large tensioning material can be made to correspond to the internal dimension between the beams using the fixed square pipe 2, so the beam side hardware 11 .11
can be used in combination, and both ends can be supported by the beam side formwork 10.10.As a result, the floor formwork material 8 can be supported by simply erecting the support 9 in the center of the main material. It is possible to greatly reduce the number of floor supports used in the early demolding method, and in addition to the above-mentioned legal framework protection in the early demolding method, conventional formwork construction methods can be used for narrow support spaces such as corridors and for light loads. It can also be used as formwork support material, and the U-shaped steel material 3 and square pipe 2 in the assembled hardware 1 are interconnected by supporting plates 5, 5 fastened by wedges 6, 6'.
It is made sturdy by being supported at two points at an appropriate distance l' by ', and therefore has practical effects such as being able to ensure satisfactory member strength as a large lumber while making the length adjustable. be.

従って、本考案組立金物実施例は、例えば早期脱型工法
