Device for the Mass Production of a Hollow Building Block from a Hydraulically-Hardening Moist Building Block Mass

Abstract

A device is described for producing a hollow building block from a hydraulically curing, moist building block compound having a mold open on top (1), which comprises core spikes (4) projecting from a mold floor (2) inside mold walls and positioned with lateral spacing to one another to implement hollow chambers of the hollow building block, and having a filling truck (9) movable along a guide (6) above the mold (1), which forms a receptacle chamber (12), delimited by peripheral walls (13), having a screen floor (14) for delivering the received building block compound. In order to achieve uniform filling of the mold (1), it is suggested that the screen floor (14), which is mounted in the filling truck (9) so it is capable of oscillation, be connected to an oscillation drive (16) and have different-sized screen openings having an opening cross-section which suppresses free passage of the moist building block compound as a result of its intrinsic weight and a distribution over the mold cross-section as a function of the course of the peripheral walls (13) of the receptacle chamber (12) and/or the mold walls and the configuration of the core spikes (4), and the filling truck (9) may be locked in a stop-delimited filling position above the mold (1).
