Abstract
In connection with casting concrete blocks with cavities, e.g. foundation blocks, perforated blocks and elements with cavities, a moulding equipment including a bottom part (4) with casting cells with pendant core members (8) bolted on corresponding to the shape of the concrete block, and a top part (14) which have pressing plates (20) projecting downwards on support rods (18) and substantially corresponding to the shape of the casting cells, and so that the pressing plates (20) by stripping the items by vertical displacement of the bottom part (4) are passed down through the casting cells (6). By the invention is indicated a bottom part (4) that include means in the form of core members (8) bolted on, forming the defined cavities in the finished block/element. The core members (8) may either be releasably bolted onto the top plate (10) of the bottom part, or, alternatively, be suspended from a yoke (12) which is releasably fastened to the mould frame, and between the mould frame and the yoke there may be a vibration dampening shim. Core members (8) may furthermore be bolted on with a vibration dampening or compact shim (2).
