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 surrounded by a material that provides the required strength.
  • AT-PS 322 165 describes a process for the production of plates, sheets or moldings which contain a heat-insulating core which is encased by a hydraulic binder, for example gypsum.
  • the process is used for the continuous production of a strip, for example 0.6 m wide and 7 cm high, which is finally cut into sheets or sheets 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.
  • 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 in contact with a pressure roller, which prevents further buoyancy.
  • the gypsum paste is introduced in such an amount that it surrounds the core about halfway up.
  • 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, none occurs at the transition point between the two layers intimate connection, so that the mechanical strength is reduced compared to a homogeneous connection.
  • 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 the strength in a mushy state, the shape is partially filled, in an upright standing form, whereupon the board is preferably immersed in the middle in the partially filled form and in their position is secured so that the plate is surrounded by the displacement of the pulpy material.
  • FIG. 1, 1 denotes the heat-insulating plate, which from organic products, such as foamed polystyrene, polyurethane, foam rubber, or from inorganic substances, e.g. expanded perlite (particularly fireproof), cottage pumice, expanded clay (LECA), glass wool, rock wool as a prefabricated element, or as a combination element of these materials.
  • organic products such as foamed polystyrene, polyurethane, foam rubber
  • inorganic substances e.g. expanded perlite (particularly fireproof), cottage pumice, expanded clay (LECA), glass wool, rock wool as a prefabricated element, or as a combination element of these materials.
  • perlite, pumice, expanded clay expanded polystyrene granules or similar light aggregates with a bulk density of less than 1.00 they 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, cellulose products or with water-soluble plastics processed into prefabricated plates.
  • 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, cellulose products or with water-soluble plastics processed into prefabricated plates.
  • the load-bearing, space-, fire- and weather-resistant material 2 of the building board produced according to the invention are preferably inorganic, hydraulically or carbonatically hardening substances, such as Portland cement, hydrophob cement, white cement, roman lime, hydrated lime or plastic-modified variants of these in pure form or with frost and fire resistant Fine aggregates, 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 a mortar is that the raw mixture increases the air pores to increase the thermal insulation and to ensure space resistance and the flexural strength may contain 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 the mold being provided with a lid before curing, which has a trapezoidal depression. This makes it possible to place the usual dowels, e.g. with masonry insulation to be significantly reduced and damage to the visible surface due to fastening to be avoided completely.
  • 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, which can consist of fibrous materials.
  • This type of attachment Possibility 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 increased air pressure at high speed to a highly porous mass and brought into a high 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 a bracket on the end faces or along 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 plate made in this way for example 100x60x8 cm, had a density of 300 kg / m 3 after curing, the mean breaking load was 50 kg with a span 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 is in an upright form, in which a synthetic fiber mat, which also has an analogous effect, is subsequently introduced, as in Example 2.
  • 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.
