  • Aerated concrete is a hydrothermally cured, porosated calcium silicate hydrate material. It is produced from aqueous mixtures of at least one mineral binder which contains at least one CaO component which is reactive in the hydrothermal process, for example cement or quicklime or hydrated lime, and at least one SiO 2 component, eg quartz flour or fly ash, a blowing agent, in particular aluminum powder. and / or paste, and optionally inert additives and / or additives.
  • This fresh concrete mass is poured into molds, floated and stiffened, cut and then subjected to steam hardening.
  • prefabricated foam is mixed in place of the blowing agent.
  • the fresh concrete mass is filled into an upwardly open mold and left in this driving and stiffening. If the fresh concrete mass has reached a sufficient green state or cutting strength, the two side walls and the two end walls of the mold are folded away.
  • the green cellular concrete cake is now gripped by means of a lifting device, lifted and transported by lateral displacement to a cross-cutting device.
  • a hardening residue is arranged, which two outer Longitudinal beams and has several cross bars. On the crossbar are numerous in the transverse direction spaced longitudinal bars. By means of spacer pins, the position of the longitudinal bars is determined.
  • profiled transport shafts are driven against the longitudinal bars from below and the longitudinal bars are lifted off the hardening rust by means of the transport shafts.
  • the transport shafts have circumferential, annular grooves, in each of which a longitudinal bar engages positively.
  • the transport rollers pass through the spaces between two mutually adjacent crossbar of Hardenosts during startup.
  • the longitudinal cutting of the aerated concrete cake takes place.
  • the individual green shaped bodies are only abutted again, so that the resulting transverse cutting gaps are closed in order to ensure a clean slitting.
  • the two impact devices engage the two end faces of the cross-cut aerated concrete cake and push the individual aerated concrete molded bodies together again.
  • the second bumper is seen in the cake transport direction arranged in front of the longitudinal cutting frame.
  • the impact devices each have individual slats.
  • the slitting now takes place.
  • the cross-cut porous concrete cake is pushed through the rear bumper by a vertical cutting wires having longitudinal cutting frame and thereby cut longitudinally.
  • the longitudinal bars are driven through together with the cellular concrete cake by the longitudinal cutting frame between the cutting wires. They drive the transport waves.
  • Behind the longitudinal cutting frame are also profiled transport shafts which receive the longitudinal bars. After slitting the transport shafts are lowered, so that the longitudinal bars are arranged with the arranged thereon, longitudinally and transversely cut porous concrete cake lowered to a waiting hardening.
  • the two impact devices thus also engage during the longitudinal cutting process on the two end faces and thus support and push the cellular concrete cake during the longitudinal cutting process.
  • the two impact devices move together with the cellular concrete cake in the cake transport direction.

  • the small width is necessary so that the width of the aerated concrete moldings can be varied in the smallest possible steps. Due to their small width, however, the longitudinal bars can press into the still soft cellular concrete material. In addition, the longitudinal bars must be guided in the deep grooves or grooves of the transport shafts to avoid the running of the longitudinal bars.
