Definitions

  • the invention initially relates to a method for producing a rainproof wall element in sheets or pallets, according to the preambles of claims 10, 11 or 19, and a wall according to claim 18.
  • the invention is based on the object of specifying a method for producing a rainproof wall element which is easy to carry out in particular in series production, which results in a wall element which is to a large extent rainproof, does not cause frost damage, can be carried out inexpensively and conveys an optically appealing appearance. It is a further object of the invention to provide a rainproof wall element and a wall which are simple and inexpensive in their construction and can be easily manufactured.
  • the invention enables the construction of a wall element, the main component of which consists of gas concrete, which, however, imparts rainproofness and an attractive appearance due to the layer of concrete in front, in particular washed concrete.
  • the non-reinforced facing layer is applied by means of an adhesive and barrier layer, which prevents water from penetrating and mediates good adhesion between the facing layer and the gas concrete element.
  • the series production of such a wall element is simple, since conventional pallet or sheet production can be used.
  • Fig. 1 shows a cross section through a wall element according to the invention.
  • Fig. 2 shows a wall with two wall elements.
  • a gas concrete element 1 is provided with a facing concrete layer, in that the facing layer is connected to the gas concrete element by means of an adhesive and barrier layer, preferably an adhesive emulsion based on polyvinyl acetate.
  • an adhesive and barrier layer preferably an adhesive emulsion based on polyvinyl acetate.
  • a polycondensed heterocycle-modified cement-bound adhesive bridge is preferably used, which, for. B. under the designation "Addiment Haftmaschine 1" from the company Addi ent. _ H. _
  • This barrier layer can first be applied in viscous form directly to the gas concrete layer in such a way that the pores of the gas concrete are sealed. Then the concrete facing layer is applied or placed on, the pores of the gas concrete being further sealed and an intimate bond between the gas concrete and the facing layer. However, the barrier layer can also first be applied to the concrete facing layer, to which the gas-concrete layer is then applied.
  • Fig. 1 shows a cross section through a wall element according to the invention. Only a thin barrier layer 3 with a thickness of 5-20 mm is applied to the gas concrete element 1, to which the facing element 2 is applied. A wash concrete layer is primarily used as the facing concrete layer. This layer is neither reinforced nor provided with composite anchors. Because even a reinforcement does not prevent hair cracks caused by shrinkage or temperature fluctuations. Gas concrete has a compressive strength of less than 15 N / mm 2 and a bending tensile strength of approximately 1 N / mm 2 . In contrast, the compressive strength of the concrete used is more than 35 N / mm 2 and the bending tensile strength is more than 5 N / mm 2 . This leads to a significant increase in the resilience and resistance of the outward-facing layer than is possible with plasters whose compressive strength is below 2.5 N / mm 2 . _ ⁇ ⁇ _
  • the concrete layer is preferably reinforced, so that the gas concrete is encircled by the concrete layer.
  • Fig. 1 shows with the numbers 4 and 5 the reaching behind a paragraph of the gas concrete layer 1st
  • FIG. 2 shows two adjoining gas concrete layers, each of which is provided with a wash concrete facing layer.
  • the two wash concrete layers each engage behind the gas concrete layer with the projections 6 and 7.
  • a seal 8 is inserted between two wall elements, which is preferably inserted between the opposite edges of the two facing layers of the gas concrete elements 9 and 10. This means that rainwater can never reach the gas concrete layer.
  • the individual wall elements are preferably connected to one another with the aid of an adhesive 11.
  • Wall elements according to the invention are preferably produced on a web paver or in a pallet production facility. It is possible that the washed concrete is applied to an underlying gas concrete layer (positive process), and that the washed concrete is located below (negative process). In the case of web production using a rail-based paver, the application of the barrier layer, if this is applied separately, the feeding, wiping and shaking of the concrete, as well as the shaping by means of sliding formwork, can be carried out directly by the paver after the gas concrete conversion ö -
  • the elements have been inserted below.
  • the elements can also be washed out with a rail-bound, mobile washing system.
  • the web production method is particularly suitable for economical production, a pallet production is also conceivable, in which the gas concrete elements are placed in a formwork, for which purpose two side formworks are removed in each case.
  • the barrier layer is then introduced in a further station if this is applied separately, and the application of the concrete is then expediently carried out in a further station which is followed by the vibrating station.
  • a test wall was alternately subjected to such a frost / thaw change fifty times by inflating cold air at -20 ° C. and by sprinkling with water at + 20 ° C. Before the start of the test, the test specimen was sprinkled with water for about 8 hours. After the test wall had been divided, no change could be found either on the visible side or at the joint between the facing concrete and gas concrete.
  • the method can also be carried out by swabbing the concrete layer with a water-impermeable substance, preferably a polymeric agent, and then applying it to the gas concrete element in one operation without reinforcement.
  • a suitable agent is e.g. B. Addiment BV 3 from Addiment.
  • a correspondingly created wall element is characterized in particular by the simplicity of manufacture and good rain-repellent properties.
  • a further possibility of establishing the watertightness is to apply a concrete layer of a certain thickness, for example 5 cm, with an adhesive tensile and compressive strength to the gas concrete element which is at least twice as high, preferably more than three times as high, as the corresponding ones Values of the gas concrete element, with no addition being necessary.
