Moulding table for concrete plates

摘要

A device for manufacturing plate-shaped concrete structural elements with elongate internal cavities is described. The device consists of a moulding table, in which any number of core tubes is arranged parallel to the horizontal table surface. The core tubes (8) have suction openings (10) which are directed towards covers (9). The inner ducts (11) of the core tubes can be connected to a suction device. A low pressure is created which secures the covers even during filling of the concrete and during subsequent handling. <IMAGE>
