A reinforcing cage for moulding artificial stone materials, particularly light-weight aerated concrete, comprising a first group of elongated, mutually parallel reinforcing irons (1) intended to reinforce the upper edge or side surface of a slab moulded from the artificial stone material, and a second group of elongated, mutually parallel reinforcing irons (2) intended for reinforcing the bottom edge or surface of the same slab, the groups of reinforcing irons being held together by transverse stirrup-like devices (3, 4). Such slabs are primarily used in the construction of ceiling structures and beams, joists, etc., in various kinds of building constructions. In accordance with the invention, the legs (5, 6) of the transverse stirrups incorporated in a reinforcing cage or the like of the aforesaid kind are held in a sprung state, i.e. against the action of a spring restoring force, with the aid of hooked cross-connectors (8) or like devices. The invention also relates to a method for manufacturing the reinforcing cage. |
