Abstract:
A method and apparatus for casting concrete elements with varying, determined length, equipped with one or with a plurality of longitudinal hollow cores, by means of a slipforming apparatus. The apparatus is movable with respect to the bed (2), said apparatus comprising forming members (10) for forming hollow cores. The mass is fed in the first step to the portion of the slab below the hollow cores, and in the second step the hollow-core forming members being brought onto the said portion of the slab and mass is being fed between the forming members and onto them. The forming member (10) for forming a hollow core comprises an attachable extension part (22). The height of a hollow core is changed by changing the extension part of the hollow core forming member.
