Definitions

  • the invention relates to a plant for manufacturing of steam-hardened building materials.
  • Steam-hardened building materials in particular steam-hardened lightweight building materials, for example porous or gas concrete, are produced using the following process.
  • the ground raw materials sand, lime, cement, sulfate carrier and aluminum powder are metered in batches together with water in a mixer. After mixing, the material is poured into an oiled mold with a volume between 4 and 9 m 3 . After the casting mold has been filled, it is brought to a fermentation place, where the mass is fermented to its final volume and remains between one and six hours until the binding component has set enough green strength for the sawing. When the green strength is sufficient, the material is removed and then cut using wires in a sawing station.
  • the material After sawing, the material is either collected at further locations in front of the autoclave until there is an autoclave filling or it is fed directly into the autoclave. After autoclaving, the usual autoclaving time is approx. 12 hours, the material is removed from the autoclave, unloaded in a discharge device, packaged and transported to the warehouse.
  • the cleaned and oiled Molds filled with an aerated concrete mixture and then on Proofing stations 102 move where the mass floats in the molds and sets.
  • the green ones become in a demolding station 103 AAC cake tilted by 90 ° and part of the mold removed, while a mold side wall is used as a hard floor remains.
  • Another possibility is the implementation of the cellular concrete cake on grids so that the entire shape is removed becomes.
  • the aerated concrete cakes are then placed in a cutting station 104 driven and cut there in the desired formats.
  • the shapes taken from the cellular concrete cakes are in a cleaning station 105 cleaned and then in one Oil station 106 oiled.
  • the hard floors, each with a cellular concrete cake, are now three with their long sides next to each other or with their broad sides placed one above the other on autoclave or hardening car 107 and in entered a tunnel 108, which prevents them from cooling, in particular Train to protect. From tunnel 108, the aerated concrete cakes, if sufficient autoclave trolleys for one autoclave filling stand ready, run into a free autoclave 109 and subjected to steam curing there.
  • the cellular concrete cakes are made the autoclave 109 extended and then stand for an aftertreatment and / or packaging on a stand 111. If the aerated concrete cakes are equipped with reinforcements should be in a reinforcement station 112 before casting Reinforcements are inserted into the forms.
  • CH-A 281 682 is a plant for the production of concrete slabs, especially the steam-hardened, frame-reinforced Lightweight concrete slabs are known.
  • This known system is essentially housed in a temperature-controlled hall, whose interior temperature on a for the requirements of gas concrete or Foam concrete production can be adjusted to the required dimension. With this system, it is disadvantageous that it has a considerable Space requirements and an enormous investment for the structural measures required.
  • the object of the invention is to provide a system in which the economic production capacity and the space required considerably is reduced and the clock rates during production are increased.
  • this makes a particularly compact system achieved that all functional lines arranged parallel to each other are.

  • the saw as well as the heat chamber above the autoclave and the heating chamber may be arranged, the heating chamber over the heating chamber is arranged.
  • the invention Combination of this embodiment of a plant with the warming up and heating up of both the aerated concrete molds fermenting mass as well as the ready-cut cellular concrete cake enables a compact system to be achieved on the one hand, because the parking spaces in front of the autoclaves are eliminated, on the other The entire production process is significantly shortened with optimal use of energy, resulting in low production output can still be done economically.
