Definitions

  • the invention relates to a method and an apparatus for the production of gas concrete bodies in the preambles of claims 1 and 9 mentioned art.
  • Such methods and devices are generally known and can, for example, the German patent specifications DE-A-29 23 626 or DE-A-29 26 379 can be found. There too explains that after soaking and partially curing the further processing steps of the mass in the molding box e.g. may consist in that in Molding box located semi-solid block after one turn formed around its longitudinal axis by 90 °, in the desired Gas concrete elements cut and then in an autoclave under pressure at temperatures of about 180 ° C about 15 Steam-hardened for hours.
  • the cutting process can either be carried out that ultimately gas concrete "stones" are formed, which on the Construction site to be put together to a masonry.
  • plates can also be made from the partially hardened block can be cut out, possibly with reinforcement elements are reinforced, which before pouring the mass coming from the mixing device into the molding box were used in these.
  • the invention is therefore based on the object of a method and a device for carrying it out to improve the type mentioned so that the for above-mentioned relevant parameters target values can be achieved with greater reliability.
  • the invention provides the Claims 1 and 11 summarized process steps or characteristics.
  • a particularly easy way to do the vibrations to put on the molding box is to be against his Floor in the area of one of the floor longitudinal edges at two in Direction of this longitudinal edge spaced locations to press plates connected to unbalance motors, which the vibrations generated by the balancing motors on the molding box transfer.
  • the vibrating frequencies are preferably in the range of 10 Hz to 50 Hz, the higher frequencies being favorable, the higher the target bulk density.
  • a particularly high saving in aluminum powder can be achieved in the production of aerated concrete based on lime, in which the sludge is 37% to 43% sand by weight, 8% to 12% return goods, 10% to 16% lime, 3% to 5% cement and comprises 30% to 37% water. These muds can then Depending on the desired bulk density, about 0.06% to 0.15% aluminum powder be added.
  • the invention has proven to be particularly advantageous Proven method in the manufacture of gas concrete bodies those to increase their tensile strength with reinforcements, for example are made of structural steel. These reinforcements before pouring the gas concrete mixture into the molding box inserted in this and positioned there so that they were enclosed by the poured mass as it rose be and in the partially hardened gas concrete body are in their desired end position. In the casting process the problem arises without a shaking process the so-called trailing shadow. Underneath is the fact understood that the density and thus the compressive strength of the finished gas concrete element seen in the climbing direction often significantly lower behind the reinforcement elements than in the other areas of the gas concrete body in question is. It is clear that this diminished significantly Rigidity and resilience of this gas concrete body leads.
  • the molding box 1 shows a cuboid shaped box 1 open at the top, as it is used for the production of gas concrete.
  • the molding box is double-walled in such a way that its inner and outer walls connected by webs Enclose cavities through which a coolant, for example Water can be pumped.
  • Such a molding box is used to manufacture gas concrete about a third of its volume with an aqueous one Sludges from sand, lime, cement and other aggregates filled the aluminum powder just before pouring into the molding box as a blowing agent or blowing agent is.
  • the molding box 1 Immediately after filling, the molding box 1 is in the brought position shown in Fig. 1 on the hall floor 2, in which he with his one longitudinal edge 4 over two in Direction of this longitudinal edge spaced from each other Openings 6 is located in the hall floor 2.
  • the molding box 1 remains at least as it is long until the shortly after adding the aluminum powder rising process is completed, during which the mass in the molding box 1 its volume so strong enlarges that with its upper surface approximately the height of the upper edge of the molding box is reached or even slightly exceeds.
  • each of the openings 6 there is under each of the openings 6 a shaft 8 in which a Vibrator arrangement 10 is housed.
  • This vibrator assembly 10 includes one on the shaft bottom a hinge 11 supported and substantially vertical arranged hydraulic or pneumatic cylinders 12, the upwardly projecting piston rod 14 via a joint 15 carries a box-shaped housing 17, with the hall floor 2 roughly aligned top with a plate 18 made of hard elastic material, for example hard rubber is occupied.
  • an unbalance motor 20 arranged in its Frequency and amplitude of variable vibrations on the housing 17 transmits.
  • the top of the housing 17 which is occupied by the plate 18 can be pressed with the aid of the cylinder 12 against the bottom of a molding box 1 positioned above the opening 6, so that the vibrations generated by the unbalance motor 20 are transmitted to the molding box 1.
  • a molding box with a usable volume of 4.5 m 3 and a total weight of 12,000 kg (with cooling water and filled gas-concrete mixture), a pressing force of 10,000 N has proven to be favorable for each of the two vibrator arrangements 10. At this force, the molding box 1 is not yet lifted off the hall floor 2, but the contact with the plates 18 is so good that the vibrations generated by the unbalance motors 20 are well transmitted to the molding box and the gas concrete mass contained in it.
  • the molding box 1 is a few seconds after pouring the gas concrete mixture in the position shown in Fig. 1 brought, so the two cylinders 12 of the vibrating assemblies 10 actuated and the housing 17 from below in the area of one longitudinal edge 4 to the bottom of the molding box 1 pressed, and the unbalance motors 12 in motion set.
  • different vibration frequencies selected. So have yourself a frequency for gas concrete with a bulk density of 0.4 of 13.5 Hz, with a bulk density of 0.5 a vibration frequency of 28 Hz and a vibration frequency for a bulk density of 0.6 of 32.5 Hz proved to be favorable.
  • the shaking process is like this long continued until the mass rising in the molding box 1 a height of about 10 cm below the upper edge of the molding box has reached. Then the unbalance motors 20 are switched off and the molding box 1 is left in place until the Climbing process is completely finished.
