Definitions
- the invention relates to a wall structure for building exterior walls with a load-bearing wall in the manner of a hollow wall, bricked or filled wall whose outer wall side is applied an insulation layer that with Fasteners are attached to the load-bearing wall as well as with a the insulation layer applied top layer.
- the Thermal insulation layer applied a thin top layer, which a clean, area-wide facade results.
- cover layers for example also used plates.
- Can on this top layer then immediately plaster layers or in the case of inner walls Wallpaper can be applied.
- Thermal bridges are thermally well conductive areas over which the thermal flow without major Losses can escape to the outside better than in neighboring areas.
- Classic thermal bridges are thermally conductive fasteners that are made of Metal or plastic are made, for example, directly from the load-bearing masonry to the area below the top layer. Such Fasteners are used for example to fix Thermal insulation layers on the load-bearing masonry.
- the due to an increased heat flow from inside the building form appropriate thermal bridges in the area of the outer surface.
- the Increased, local heat flow creates warmer areas on the outer wall surface that dry faster compared to their cooler surroundings, which makes visible drying spots arise.
- the invention has for its object a wall structure for Building exterior walls with a load-bearing wall in the manner of a hollow wall, bricked or filled wall, on the outside wall an insulation layer is applied, which is fastened with fasteners against the load-bearing wall and with a covering layer applied to the insulation layer, such train that the disadvantages mentioned above, especially training of drying stains should be avoided completely.
- a wall structure for building outer walls with at least one Intermediate layer which has an outer and inner surface, according to the Preamble of claim 1, designed such that in the top layer flat heat-conducting layer in the manner of a mesh, network, preferably one metallic coated reinforcing fabric is introduced.
- the heat-conducting layer With the help of the heat-conducting layer, one possibility is created uniform temperature distribution in the top layer, for example as a surface layer trained to be brought about.
- the heat-conducting layer that extends laterally possible thermal bridges between the masonry and the top layer, is used to distribute heat flow across locations of existing thermal bridges their longitudinal extension.
- Metallic ones are particularly suitable for such heat-conducting layers Braids, for example in the form of a metal-coated reinforcement fabric.
- Reinforcement fabrics are used to reinforce mortar layers anyway Insulating layers of material used, so that by a previous Coating the fabric with a thermally highly conductive material no Additional effort for the construction of wall structures is connected.
- Such Known reinforcement fabrics consist of a plastic fabric and serve only the avoidance of cracks within the top layer.
- a conventional wall structure is shown, the load-bearing Wall section (1), in the form of a wall.
- the load-bearing wall element 1 can, for example, as brick masonry, concrete wall or as a lime-sandstone wall be trained.
- An interior plaster 2 is applied to the wall side, which is directly on the inside of the Wall element 1 is provided.
- a heat-insulating layer 3 which has a corresponding Adhesive layer is attached to the wall element 1.
- Fastening elements 4 here in the form of dowel connectors, for firm and secure Hold the insulation layer 3 against the load-bearing wall 1.
- a surface covering layer 5 e.g. a layer of plaster, intended.
- the fastening elements 4 are generally designed as metal screws, can however also be made of plastic.
- metal screws represent and are thermal bridges due to their good thermal conductivity Causing the formation of drying stains that are on the exterior plaster form on the top layer 5.
- FIG. 1b shows a schematic stator construction, with an inner 2 and outer cover 5, which are mutually connected via holding elements 8 are connected and spaced apart.
- an inner 2 and outer cover 5 which are mutually connected via holding elements 8 are connected and spaced apart.
- Thermal insulation layer 3 introduced to ensure thermal protection.
- 8 metal pins are used for the holding elements in turn have good thermal conductivities.
- a wall construction according to the invention which has a structure similar to that of the wall construction shown in FIG. 1a, with the addition that a between the top layer 5 and the thermal barrier layer 3 thermally conductive intermediate layer 9 is introduced, which is parallel to the entire surface below the top layer 5 and transverse to the longitudinal extent of the Fasteners 4 extends.
- the preferably as metallized Plastic reinforcing fabric formed thermally conductive layer 9 covers the end regions of the fastening elements 4 designed as metal screws represent heat transfers as described above.
- the heat-conducting intermediate layer 9 shown in FIG. 2b can be flat formed network or braid made of thermally highly conductive material or a fabric.
- Flat mesh or mesh constructions or Tissue arrangements are also due to technical reasons better adhesion properties and easier processing options continuous sheet metal is preferable.
- plastic fabrics or Plastic reinforcements through appropriate coating with heat-conducting Materials, preferably metals, for the heat-conducting intermediate layer 9 can be used, which ensure a thermally homogeneous surface.
- a corresponding heat-conducting intermediate layer 9 is not between in FIG. 2a the supporting wall element and the interior plaster 2 provided, but can also stains in the interior of apartment buildings in the area of thermal bridges occur, especially during long cold periods or high humidity Lead to mold formation.
- a conductive intermediate layer in the plaster can Defuse deficiencies; a copper-coated one is suitable for this Reinforcement mesh.
- FIG. 2b shows a wall construction corresponding to the representation in FIG. 1b in FIG Stand construction shown.
- a heat-conducting intermediate layer 9 is provided, which the heat flow from the Thermal bridges, which represent the holding elements 8 in detail, transversely to the surface deduce.
- the fastening elements 4 and holding elements shown in FIGS. 2a and 2b 8 have head-shaped for the sake of fixing the insulation layer 3 Flattenings 10 on, over the slightly spaced the heat-conducting intermediate layer 9 runs.
- the local thermal bridges represent, inhomogeneous temperature distributions can be different Set conditional thermal bridges in the surface areas of walls where differently tempered wall sections meet. So are in particular the inside corners of rooms are preferred surface areas, in which form mold areas due to different temperatures.
- This can be particularly important in the transition area between wall and ceiling worn that there is a homogeneous temperature distribution.
- the Thermally conductive layer must be in particular in wall ceiling transitions connected, i.e. run without interruption.
