かである。 As described above, the concrete formwork connecting fittings according to the present invention are assembled and used, but the connection is made in two ways.
Since this is done by one or three connecting pins, it is strong enough to withstand tensile force in particular. Further, since the end portion of the intermediate bar and the connector have a substantially U-shaped cross section, they have sufficient strength against bending force. In addition, long holes are formed in the intermediate bar to facilitate concrete pouring, but since the intermediate bar has a sloped band and a horizontal band, it is sufficiently strong, and the connecting pins are If there are at least two of them, the strength will be sufficient. Furthermore, since there is no need to insert pins as in conventional products, only one worker can assemble the connections, and since assembly is simple, construction costs can be reduced. It is clear that the concrete formwork connection fitting according to the present invention can be used by further interposing a bar between the intermediate bar and the formwork.
