Definitions

  • the invention relates to a method for producing a heat-insulating building board, which consists of at least one board made of heat-insulating material, which is enclosed by a material that provides the required strength.
  • AT-PS 322 165 a process for the production of plates, sheets or moldings is described, which contain a heat-insulating core, which by a hydraulic binder, for. B. plaster is coated.
  • the process serves for the continuous production of a z. B. 0.6 m wide and 7 cm high strip, which is finally cut into sheets or plates of the desired length, so that the ends are not covered by the binder.
  • the process is divided into several steps. First, the core is inserted into a mold consisting of a conveyor belt and rubber bands on the side. In the subsequent step, the rubber bands on the side expand and the gypsum slurry is poured into this lateral expansion, so that the core is raised due to the buoyancy until it is against a pressure roller that prevents further buoyancy.
  • the gypsum paste is introduced in such an amount that it surrounds the core about halfway up. After the gypsum slurry has hardened, the pressure roller is removed and further gypsum slurry is poured in until it rises to the upper edge of the rubber bands on the side and completely covers the core, whereupon this second layer is hardened. Since the second layer of gypsum is only applied after the first layer of gypsum has hardened, there is no intimate connection at the transition point between the two layers, so that the mechanical strength is reduced in comparison with a homogeneous connection.
  • a fiber mattress is fixed in a mold by means of rods or wires and then plaster, cement or the like is poured in.
  • the object of the invention is to provide a method for producing heat-insulating building boards in one-off production, which meet the above-mentioned requirements through a combination of materials or a material structure, have a high flexural strength and can be produced with a small number of work steps.
  • the process for producing a building board of the type mentioned is characterized according to the invention in that the material giving strength, in a mushy state, is partly filled in an upright shape, whereupon the board is preferably immersed in the middle of the partially filled form and in their position is secured so that the plate is surrounded by the displacement of the pulpy material.
  • 1 denotes the heat-insulating plate, which is made of organic products such.
  • B foamed polystyrene, polyurethane, foam rubber, or from inorganic substances, for.
  • Rock wool exists as a prefabricated element, or as a combination element of these materials.
  • perlite, pumice, expanded clay foamed polystyrene granules or similar light aggregates with a bulk density of less than 1.00 these are mixed with an inorganic binder such as Portland cement, alumina cement, aluminum cement, hydrophob cement, Gypsum, hydraulic lime, hydrated lime or with other binders, such as sulfite waste liquor, cellulose products or with water-soluble plastics, processed into prefabricated boards.
  • an inorganic binder such as Portland cement, alumina cement, aluminum cement, hydrophob cement, Gypsum, hydraulic lime, hydrated lime or with other binders, such as sulfite waste liquor, cellulose products or with water-soluble plastics, processed into prefabricated boards.
  • the load-bearing, space-, fire- and weather-resistant material 2 of the construction board produced according to the invention are preferably inorganic, hydraulically or carbonatically hardening substances, such as Portland cement, hydrophob cement, white cement, roman lime, lime hydrate or plastic-modified variants of these in pure form or with frost and fire resistant Aggregates in fine shape, preferably less than 10 mm grain size, in question.
  • An essential feature of this raw material mixed with water to form a cement paste or mortar is that the raw mixture can contain air pores to increase the thermal insulation and to ensure the spatial stability and the flexural strength of fibrous materials.
  • the fibrous materials consist of loose and / or of coherent plastic and / or glass fibers and or or mineral fiber materials, which according to the process of the invention are either mixed with the binder in the preparation of the mixture or only those that are already in the mold not hardened mass can be added.
  • the shape used for producing the building board can have a trapezoidal depression on the bottom, so that the building board has a trapezoidal spring at this point.
  • a corresponding groove on the upper side of the building board can be produced, for example, by providing the mold with a cover before curing, which has a trapezoidal recess. This makes it possible to place the usual dowels, e.g. B. with masonry insulation to reduce significantly and to avoid injury to the visible surface due to attachment.
  • the building panels produced in the example according to FIG. 2 can have a semicircular tongue, the complementary semicircular groove being provided, for example, in the heat-insulating panel 1 itself.
  • a fastening strip can be cast in according to the example according to FIG. 2, which can consist of fibrous materials.
  • This type of attachment can also be replaced by individual tabs, plates or hooks that are anchored in the building board.
  • the space required for the connection plate is taken into account by a corresponding recess (not shown). It is envisaged to provide the visible surface of the plates with a coloring and / or with a structuring layer.
  • a cement paste based on Portland cement is mixed with 0.1% air-entraining agent and with a fiber content of 2.0% by volume in a compulsory mixer under high air pressure at high speed to a highly porous mass and brought into a high-quality form.
  • the form is only filled to such an extent that it is only filled to the brim with the displacement of a 5 cm thick polystyrene plate into the mass.
  • the extremely light polystyrene plate is prevented from swimming upwards by means of a bracket on the end faces or at the longitudinal edges and prevented from sliding off to the side by a guide.
  • the plate is left in the form until it has hardened to form a tongue and groove.
  • a so manufactured, e.g. B. 100 x 60 x 8 cm plate had a density of 300 kg / m 3 after curing, the average breaking load was 50 kg with spans of 50 cm.
  • the mixture is mixed in a compulsory mixer so that the cement paste with the pearlite part is first prepared and only then is the expanded clay part briefly mixed with the mass.
  • the finished mixture gets into an upright form, in which, analogously to Example 2, a synthetic fiber mat is introduced which also has an analogous effect.
  • the synthetic fiber fabric is allowed to protrude 10 cm over the entire length of the mold edge.
  • the heat-insulating material it would also be possible for the heat-insulating material to be introduced into the mold first, whereupon the strength-imparting material is introduced in a slurry form.
  • the strength-imparting material is introduced in a slurry form.
