METHOD AND APPARATUS FOR PRODUCING CONCRETE PRODUCTS

摘要

A method of casting concrete elements comprising one or more longitudinal hollow cores. When casting is started, forming means (4) provided in the apparatus are pushed through openings in a headplate located at the front end of the element to be cast and fresh concrete is pressed against the headplate by means of feeding screws (3) provided in the apparatus. When casting the back end of the element to be cast, the casting apparatus, as well as the feeding screws (3) and the forming means (4) thereof, pass over a part (10) mounted on the casting bed (1) to form the lower part of the endplate of the form. The feeding opening of the apparatus is covered by a covering means (8) and a part (11) provided in the apparatus to form the upper part of the endplate of the form is pushed above the lower part (10) of the endplate of the form. Openings are formed between the upper part and the lower part of the endplate, allowing the feeding screws (3) and the forming means (4) to pass through.
