Aerated concrete slabs joining and anchoring fish-plate - has connecting bearer detachably joined to plate carrying hammer-head

摘要

The anchor fishplate is used for connecting abutting slabs of aerated concrete, with hammerhead for anchoring these in an anchor bar. The connecting fishplate (1) is made up from a connecting support piece (2) for joining the concrete slabs together, together with a fishplate (3) bearing the hammerhead (31). The connecting support is detachably connected to the latter fishplate, and/or notches into position with it. The two may be form-locked together. The connecting support piece may be a panel-shaped unit stiffened by a lengthways seam (21), with form-locking media (23) set vertically to its plane and similar media vertical to the seam's extension. This can be made from a narrow strip of rustless steel, with min. punch wastage, and only a single fishplate of thicker plate is needed.
