FORMING METHOD OF CONCRETE WARE AND DEVICE THEREFOR

摘要

This invention relates to building industry, and it can be used to manufacture following products: concrete pavers/paving stones, road plates, wall blocks, decorative plates, as well as for military applications, for example, aerodrome coverings, underwater buildings and other concrete elements. The offered method is characterized in that concrete products are formed from a concrete mixture that has been vibrationally obdurated simultaneously in the two sinusoidally vibrated extrusion forms that are positioned one above other and exposed sequentially to shock-impulses with predetermined phase shift until the moment when internal resistance to pressing forces does not decrease anymore. An equipment developed for this method consists of one or more identical blocks, executed as three immobile traverses that are strengthened together with columns and as oppositionally mounted working cylinders and extrusion forms making the upper and the lower production levels, as well as it is provided with pulse-impact system is made of different productivity pumping stadions having primary and secondary output branch circuits. Change of internal resistance of the concrete mass due to influence of impact pulses characterizes the compacting degree of concrete mixture. When this resistance reaches its maximum and becomes invariable, the particles of a filler do not regroup anymore and concrete mixture has reached its maximum density. As a result, the concrete production has got the maximum quality parameters.
