Definitions

  • the invention relates to a , preferably cuboid, building block according to the preamble of claim 1.
  • a building block of this kind e.g. in EP-A-0599283 and can also be a brick be. It is used to create heat-insulating walls and is with adhesive, thin bed, medium bed or a fibrous mortar that does not fall into the cavities, bricked up.
  • the cavities can be parallel to the wall surface run vertically, as with so-called perforated bricks, or also horizontally.
  • the thermal insulation to improve by clever arrangement of louvers, the transverse to the heat flow direction from one side of the block go through others completely or at least for the most part.
  • the elongated, extruded for bricks and therefore continuous cavities weaken the Cohesion, especially the transverse tensile strength of the Insulating blocks. Therefore, a minimum of Cross-sectional area of heat-conducting webs in The heat flow direction must not be undercut.
  • slot holes be calculated (Swiss Patents 476 181, 482 882 and 516 057).
  • the mean slot width is understood as Cross-sectional area of a generally elongated cavity divided by its largest dimension across Heat flow direction.
  • the number of slot holes will be averaged over a variety of in the heat flow direction guided cuts through the brick. It corresponds to one more common parameter, namely the number of Rows of slots.
  • the cavity cross sections usually face oblong shapes such as ellipses across the heat flow direction, Rectangles, trapezoids, cuboids, triangles, etc.
  • the cavities can also be square, round, five, six and have polygonal shapes.
  • the web thickness is 6 mm and more common. If the web thickness is reduced, for example to 4 or 2 mm, so increases based on the above mentioned patents the optimal number of slot holes very strongly, so that brick with the theoretically determined optimal number of slots rows can no longer be produced can, because when extruding the clay masses much too high Pressures arise.
  • Today produced 30 cm thick Bricks usually have 17 rows of slots, maximum 21 rows of holes. 30 rows of holes are currently a borderline case represent the producibility.
  • the invention is based, to isolating modules create the statically resilient to a conventional extent are, but have a much better thermal insulation than previously known, and are easier to produce.
  • the coated inner cavities do not need to to be provided with additional insulation inserts because the coating of the cavities is due to the heat exchange Radiation between the opposing ones Ridges delimiting the cavity are sufficiently reduced.
  • the cheapest thermal conductivity values are included Cavity widths less than 3 cm realized, otherwise Convection currents can arise in the cavity. From the same reason is the height of the cavity to a stone height of usually 25 cm and make sure that the cavities do not connect to channels when bricked up, but separated from each other by a layer of mortar. This can be achieved in particular in that a building block with large cavities up to three centimeters wide next to this also has small cavities that when bricking be sealed by the mortar used and the cover large cavities.
  • the heat reflective layer can be aluminum or a contain similar heat reflective component. In question there are also various oxides such as zirconium oxide, titanium oxide, Magnesium oxide etc.
  • the heat-reflecting component can in Clay, in a glaze, a varnish or any Cover layer embedded or connected with an adhesive layer be.
  • a preferred method of applying the heat reflective layer is that this on the traditionally produced insulating block or is sprayed on. Especially with bricks suggested that if a smooth surface is necessary before applying the heat reflecting layer as Underlay for this a glaze is applied. This forms a hard, smooth surface on which z.
  • the cavities can also be coated by spraying a synthetic resin paint with reflective components done because the coating does not have high temperatures is exposed.
  • To coat insulating modules in particular bricks
  • the mass to be molded or the clay water-soluble products with a low Emission coefficients are added.
  • the Drying and firing processes migrate to the Surfaces of the blank and coat it evenly. If this on the wall-parallel outer surfaces Coating is undesirable, this can be brushed off or be sanded.
  • Another possibility of coating is that a glaze containing the heat reflecting component is co-extruded with the molding.
  • the glaze is included great pressure over the cores of the mouthpiece.
  • the effectiveness of a heat reflective coating can be by the so-called emission coefficient ⁇ specify numerically. With burnt clay it is or cement-bound lightweight building materials without coating 0.93, at aluminum-coated surfaces, on the other hand, only 0.05. Paints with aluminum bronze have one Emission coefficients ⁇ of about 0.20 and therefore quite suitable for coating the cavities.
  • these bricks are designed so that the the respective hole pattern should be added to adjacent brick ends. Accordingly, not only are the inner surfaces of the cross section differently shaped, to the storage area of the brick vertically running holes 2 heat reflecting coated, but also the butt surfaces 1 to also the Inner surfaces of the trapezoidal, rectangular or to capture wedge-shaped grooves in which after the Joining the bricks also through heat transfer Radiation takes place.
  • On the visible sides 3 are the Wall thickness of the brick 6 mm thick. The The wall thickness of the inner webs is 3 mm.
  • Masonry made with such bricks achieves a k-value of 0.38 W / m 2 with a wall thickness of 30 cm unplastered, taking into account the standardized heat transfer coefficients and with a thermal conductivity of the cullet material of 0.30 W / mK for non-reflecting inner surfaces K.
