ABSTRACT:
The invention relates to an installation for the manufacture of a large range of small and medium products of reinforced and unreinforced concrete.
This installation comprises: a series of boards A, an installation B for distributing the concrete, smoothing, and discharging the hardened products from the installation and for cleaning and oiling the boards; a tilting frame C with one or two rows of molds; a device D, for introducing boards onto the frame; some molds or batteries of molds E, provided with concrete-deareating means; and a hardening system F, dismountable and usable either in an overhead installation or in a below-ground installation.
This installation ensures, apart from diversification of production, a substantial improvement in the quality of the products and in their cost price.
