摘要:
A plant for manufacturing small structural concrete elements comprises a production station and a hardening station which both are provided with means for loading or unloading from a carrier vehicle. The hardening station is formed by a steam treatment tunnel consisting of two sections which are connected by hinge means in that way that for transport of the hardening station, one section is swung in position parallel to, and alongside of the other section. During operation, both sections together form a straight elongated tunnel.

Mass production of small precast concrete elements is improved with regard to uniformity of dimensions and of concrete compactability by a novel method and apparatus for filling the concrete mix into the form and compacting the mix in the form. According to the invention the form is evenly filled with a premetered quantity of concrete mix and any surplus due to inhomogeneities in the mix is removed during compacting of the concrete.

MANUFACTURING OF SMALL CONCRETE ELEMENTS IS IMPROVED BY COMPACTING THE CONCRETE MIX IN A MOULD AND REMOVING ANY POSSIBLE FILLING SURPLUS DURING COMPACTION, THE SURPLUS BEING REMOVED IN A PLURALITY OF STEPS. A NOVEL APPARATUS FOR THE PRODUCTION OF SMALL CONCRETE ELEMENTS COMPRISES AN UPWARDLY OPEN MOULD AND A PRESS RAM WHICH IS MOVABLE IN A VERTICAL DIRECTION AND THE RAM PLATE OF WHICH MAY COVER THE FREE UPPER CROSS SECTION OF THE MOULD SAID RAM PLATE BEING PROVIDED WITH MEANS FOR THE REMOVAL OF A FILLING SURPLUS FROM THE MOULD, WHICH MEANS IS MOVABLE IN A VERTICAL DIRECTION INDEPENDENTLY OF THE RAM.
