Definitions

  • the invention relates to a monolithic, heat-insulating exterior wall system of a building.
  • Another construction of an outer wall with a monolithic lining is from the DE 20 2008 008 807 Ul known.
  • This prior art is based on a skeleton frame with vertical skeleton frame whose free space is lined with at least one non-structural component.
  • the known liners should be heat-insulating and have low building wall thickness and only carry their own load and any acting on the outside of the component surfaces, wind loads, while the building keys are received on the structural skeleton of the building.
  • the components have a width of 0.1 to 4.5 m and a vertical length of 2.5 to 12.0 m.
  • connecting means between juxtaposed components are provided, for example in the form of mineral or non-mineral adhesive or positive or non-positive connection foils.
  • the connecting means can also be folded or groove connections, screw connections or adhesive connections.
  • the Components can be made of aerated concrete, mineral foam, hard foam, foam glass or sandwich elements, consisting of a highly effective sound and heat insulation material.
  • a weather-resistant outer layer can be applied to the components and, on the inside, an inner layer suitable for a living space can be applied. This construction is very complicated in terms of the construction of the components and the equipment for receiving wind loads.
  • the object of the invention is to provide a monolithic, heat-insulating exterior masonry system that can be made relatively thin with very good thermal insulation, especially from marketable, mineral stones, easy to assemble and adaptable to different wall dimensions and its material use is relatively low and inexpensive.
  • the invention provides, in a building construction for the outer wall, a framework of horizontal and vertical support members, e.g. from pillars and beams, in front.
  • the structure absorbs the building loads and tensile forces and can e.g. be created in a steel skeleton construction or vertical reinforced concrete pillars and horizontal reinforced concrete beams, wherein the free between the support elements personallywandungsraum is lined with a non-load-bearing masonry of a variety of highly heat-insulating stones or moldings.
  • the outside air-insulating exterior walls of a building e.g. Residential building, formed by a non-supporting, heat-insulating, monolithic exterior wall system, which is not formed from large, prefabricated wall elements, but from a infill of a vertical frame with non-sustainable, highly insulating, successive and juxtaposed mineral insulation stones as a core masonry, within a or is walled up immediately in front of or behind a vertical framework.
  • the outer wall system according to the invention can e.g. also be built as Ausfachungsmauer work in residential buildings, which are traditionally made in reinforced concrete skeleton construction, and here replace the commonly used traditional viable infill masonry, which are made by the very good thermal insulation properties significant savings in both heating and cooling energy consumption.
  • the non-load-bearing outer walls of the invention which are monolithically designed by the purpose of the invention, primarily have a space-terminating and insulating, in particular heat-insulating, function. They are also able to carry their own weight and horizontal, e.g. absorb forces generated by wind and dissipate with appropriate transmission means in the static load-bearing construction. Without upgrading the core masonry is not able to suffer these forces due to low tensile strength of mineral Dämmsteine.
  • the connections of the monolithic outer wall to the static-carrying parts of the house construction is designed so that a power transmission is ensured, which the skilled artisan can easily and without further instructions.
  • the invention thus provides a completely new use of known solid Dämmsteinen with porous mineral structure, but so far have been used only for pure insulation purposes in addition to a masonry.
  • All vertical forces that act on and in a building are derived, for example, via the roof and ceiling construction, via statically supporting, stiffening inner walls and, for example, the steel supports in the outer wall into a foundation. Accordingly for example, the steel columns are located where load-bearing interior walls can not perform this function, eg on the building corners.
  • An outer wall infill masonry 1 according to the invention is e.g. in a rectangular frame of supporting vertical columns and horizontal beams of a building (not shown).
  • the outer wall infill masonry 1 consists of a core masonry 4 and at least one screed 3 per broad side surface of the core masonry 4.
  • the core masonry 4 is made of each other and side by side bricked up mineral thermal insulation bricks 2, wherein the upgrading coating 3 on the core masonry 4 over the entire surface on both outer surfaces or broad side surfaces of the core masonry 4 is frictionally arranged, resulting in the monolithic structure of the outer wall according to the invention.
  • the insulating blocks 2 consist of solidified mineral, porous structures, e.g. from a porosized calcium silicate hydrate structure of a calcium silicate hydrate scaffold 8 and pores 9.
  • the compressive strength of the insulating blocks is between 0.20 and 0.80, in particular between 0.25 and 0.50 N / mm 2 and the tensile strength between 0.04 and 0.16, in particular between 0.05 and 0.12 N /. mm 2 .
  • the calculated value ⁇ of the thermal conductivity of the insulating blocks is between 0.03 and 0.07, in particular between 0.04 and 0.05 W / mK.
  • the apparent density is between 90 and 130, in particular between 105 and 125 kg / m 3 .
  • a reinforced mineral lightweight adhesive mortar is preferably used as a work-hardening coating.
  • the mortar consists for example of at least one mineral hydraulic binder, for example of Portland cement and / or Baukalk and at least one additive with eg grain-graded grading curve to 2 mm.
  • the cured to a plaster 6 mortar has, for example, a compressive strength between 1.5 and 5.0 N / mm 2 .
  • the coating is e.g. 3 to 8 mm, in particular 4 to 6 mm thick.
  • a planar, eg textile reinforcing element 5 for example, a glass mesh fabric 5.
  • the glass mesh fabric 5 expediently has alkali-resistant glass fibers, with Glasgittermaschenweiten eg between 3 and 7 mm tear strengths eg between 1.9 kN / 5 cm and 2.7 kN / 5 cm and basis weights between 160 and 210 g / m 2 are used.
  • the coating 3 of the invention is flexible perpendicular to its plane, but can absorb tensile forces in the plane in all directions through the grid reinforcement.
  • the coating is tensile-resistant via a mineral composite and shear-resistant connected to the insulating blocks (non-positively).
  • the outer wall according to the invention is produced in the usual masonry technique from the mineral Dämmsteinen, wherein expediently the Dämmsteine are preferably glued only in the horizontal bearing joint.
  • the material of the bond 7 is expediently identical to the coating mortar material, wherein here only preferably a textile reinforcement, e.g. a mesh fabric is inserted.
