Monolithic wall building unit - has track guided concrete supply unit with electric vat hoist, and swivelling form jaws on discharge belt

摘要

A frame on a track-bound chassis has vertical guide-rails for a trolley with a support frame attached on one side. It carries a feed container and a concrete vat to supply concrete to this. One or booms (7), with electrically driven movable hoist appliance (9) for the vat, are mounted on the main frame. The container (6) on the support frame (4) is funnel-shaped, and has a belt round its discharge aperture. Jaws (16,17) for shaping are oriented along the wall being erected, on the opposite lengthways sections of the belt, swivel drives and fixing devices (22) for these being located on the container. Simple construction permits continuous concrete supply and shaping in the course of erection of walls of varying cross-section and poured in multiple lengthways layers.
