Abstract

Improvements in fasteners for formwork boards, characterized by being intended to lock the tabs of the boards, close to their roots, and by comprising a bolt with a nut at one end, a sliding element in its stem or tenon and a head that It can be passed through a pair of aligned grooves in the flanges of the boards to place a fixing surface of a rung or step of the head, in contact with the free surface of the flange on the exit side, so that the tabs can lock between that surface and the sliding element, by tightening the nut; the head is molded in such a way that when the step is in the locked position, said head practically fills the grooves longitudinally, to prevent any appreciable misalignment of the working faces of the boards.
