Definitions

  • the invention relates to a component of the type specified in the preamble of claim 1.
  • cantilevered wall parts such as balconies are connected to a corresponding false ceiling of a building, largely excluding cold bridges.
  • a component of the type mentioned is known for example from DE-B-30 05 571.
  • This component which is designed as a prefabricated component, additionally comprises a pressure element within the insulating body, which serves as a connecting core element and has dimensions corresponding to the cross section of the insulating body. This ensures that, in addition to good thermal insulation, a satisfactory load transfer is also ensured, so that the projecting wall part is held properly.
  • This known component is used in large numbers in a wide variety of buildings and has proven itself with regard to thermal insulation and load transfer. Long-term observations have shown, however, that this known component should be improved in terms of its corrosion resistance, which is affected by the enormous temperature differences between the interior of the building and the projecting wall part as well as by the changing day and night temperatures and the seasonal temperature change. While a heated building usually has a temperature of around 20 ° C, the protruding wall part is exposed to a temperature between 55 and around -15 ° C in Central European conditions.
  • the cantilevered area experiences this Wall part temperature-related movements in relation to the building due to changes in length of the (concrete) wall part protruding from the (concrete) building, which shortens in the cold and lengthens in the heat.
  • These movements of the wall part protruding from the building are followed by the reinforcement elements in the area of the insulating plate by means of corresponding, alternating bends which run essentially S-shaped through the insulating body.
  • the invention is therefore based on the object of improving the corrosion resistance of a component of the type mentioned at the outset.
  • This additionally provided elastic protective layer does not therefore represent the corrosion protection layer, but rather protects the underlying corrosion protection layer from damage, embrittlement or penetration of moisture.
  • the constantly changing edge pressure exerted by the (concrete) material of the building or the projecting wall part on the reinforcement elements is absorbed by the elastic protective layer provided according to the invention, at least in the transition area of the insulating body to these components, and at least reduced to such an extent that damage to the corrosion coating thereof Elements or the surface of the corrosion-resistant reinforcement elements is excluded.
  • the component according to the invention is thereby distinguished by a significantly improved corrosion resistance compared to the prior art.
  • An advantage of the invention is the mechanical protection of the reinforcement elements due to their elastic coating during transport and the installation of the component according to the invention.
  • Another advantage of the elastic protective layer according to the invention is the extension of the bending length of the reinforcement elements. This is achieved by the fact that the insertion area of the reinforcement elements into the (concrete) material of the components, which is provided with the elastic protective layer, also takes part in the bending process, so that the bending is distributed over a longer area of the reinforcement elements and therefore less drastically or with less deflection in particular in the insertion area, which means that this area of the (concrete) material of the components is less heavily loaded or the reinforcement elements are less stressed by the components.
  • the elastic protective layer increases the free movable length of the reinforcement elements with a sufficient layer thickness. This also applies to reinforcement elements made of corrosion-resistant materials.
  • an axial extension of the elastic protective layer according to the invention of about 15 to 30 mm into the (concrete) material is sufficient to ensure the improved corrosion resistance in the critical transition area from the insulating body to the adjacent components.
  • ribbed reinforcement elements for example ribbed reinforcing steel, it is advantageous to extend the extent of the elastic protective layer into the (concrete) material of the components.
  • the elastic protective layer is additionally formed in the entire area of the insulating body on the reinforcement elements, so that the entire area of the reinforcement elements subject to a bend in the working components is protected by this protective layer.
  • its thickness is advantageously a few hundred micrometers, in particular at least 300 ⁇ m.
  • Elastomers and / or thermoplastics, especially foamed thermoplastics, are particularly suitable as the material for the elastic protective layer.
  • thermosets are particularly suitable as the outer layer, while foam plastics are best suited as intermediate layers.
  • a lacquer resin in particular polypropylene, may be used as the innermost layer.
  • the outermost layer of the composite protective layer or the surface of the single-layer elastic protective layer is colored in a conspicuous manner and possibly marked by rings, in order to ensure correct setting of the reinforcement elements with respect to the insulating body during the manufacture of the component.
  • FIG. 1 and 2 each show only a section of a component for the heat-insulating connection of a projecting wall part 11, such as a balcony to a building facade 10, and that in a schematic longitudinal sectional view.
  • This component usually consists of a plurality of differently shaped reinforcement elements, which are inserted into an insulating body 12 so as to protrude, and with their protruding end sections are each concreted into the projecting wall part 11 and the building facade 10.
  • a single metallic reinforcing bar 14 is shown in the present case, which is coated against corrosion or consists of stainless steel.
  • Fig.1 is in the concrete material of the building facade 10 and the in the interposition of the insulating body 12 of thickness X connected to this facade projecting wall portion 11 used reinforcing bar 14 in the region of the insulating end faces 18, 18 'and in the area of the end faces of the Concrete parts 10 and 11, that is to say in the transition region of the insulating body to the concrete parts 10, 11, are provided with an elastic protective layer 16.
  • This protective layer consists of one or more layers of elastic material.
  • the reinforcement bar 14 Due to temperature-related movements of the projecting wall part 11 relative to the building facade 10, the reinforcement bar 14 is subjected to constantly changing bending stresses, the elastic protective layer 16 compressing the bar 14 from the edges A, B, C, and D of the components 10 and 11 at the insertion points of the bar 14 in these parts due to their elasticity and their dimensions and mitigates so far that it prevents the embrittlement or cracking of the corrosion coating on the rod 14 from occurring, which would otherwise lead to corrosion of the rod 14.
  • the coating 16 extends over the entire area of the insulating body 12 and a few centimeters into the concrete material of the building facade 10 and the projecting wall part 11, so that the free movable length of the reinforcing bar 14 due to the elastic protective layer 16 in comparison to a protective layer-free reinforcement bar, which is embedded directly in the concrete of the components 10, 11.
  • the elastic protective layer 16 or 17 is formed exclusively in the transition region of the insulating body 12 to the two adjoining components 10 and 11, the ends 15 of the protective layer protruding into the components 10 and 11, which lie outside the critical edge loading area, are made thinner than the protective layer located in the transition area.
  • 1 and 2 are purely schematic representations in which the relationships of the individual parts and elements to one another do not correspond to reality.
  • the thickness of the protective layer which is typically a few hundred micrometers, especially ⁇ 300 ⁇ m, is exaggerated.
  • thermoplastics are particularly suitable as materials for the elastic protective layer.
  • An example of an elastomer is ethylene-propylene tar rubber with a density of approx. 0.9 to 1.3 g / cm3, an elongation of more than 100%, a Shore A hardness of less than 90 and an ozone resistance according to DIN 53509.
  • Another example is styrene-butadiene rubber, which has the advantage of very good wear properties.
  • polyurethane elastomers and thermoplastic elastomers which have good properties such as high strength, high flexibility and elasticity. Good wear protection and good ozone resistance are also provided.
  • thermoplastics e.g. Polypropylene, polyethylene. These materials can be applied using manufacturing processes such as spraying, injection molding, pressing, shrinking or by joining plastic injection or extrusion profiles over the corrosion-protected reinforcing steel. However, there is also the other possibility of pressing injection-molded plastic parts, which are shaped as half-shells, onto the reinforcing steel. In the same way as with the elastomers, sufficient resistance to aging, ozone and temperature must also be guaranteed with the thermoplastics.
  • thermoplastics foamed by means of blowing agents have the advantage that the elasticity and the abrasion properties of the protective layer improve.
