Definitions

  • the invention relates to a permanent formwork for an adhesive bond for connection to a building or a part of a building according to claim 1.
  • Buildings or bridge structures or buildings are made of a variety of materials, such as concrete, natural stones or bricks. At such structures often the widest variety of objects to be attached. These are, for example, railings or the like. The attachment of such parts is usually done by the use of dowels. The dowelling of such elements for attachment to such a structure is technically relatively complex, considering that often a variety of holes must be drilled, which serve to receive the corresponding dowel and subsequently the corresponding screws.
  • the document DE 198 29 401 A1 describes a lost formwork, which is connected by reinforcing elements with a building.
  • the object underlying the invention is to provide a permanent formwork of the type mentioned above, which acts as an adapter and opens up the possibility of forming the basis for an adhesive bond.
  • the adapter has for an adhesive bond for connection to a building or the part of a building on reinforcing elements, through which the adapter with the Structure is connected, wherein the adapter has a concrete head with a compressive strength of> 150 N / mm 2 .
  • a high-strength or ultra-high-strength concrete which is also known by the term "UHPC" concrete, exhibits a surface tensile strength of 15 to 25 N / mm 2 due to its constitution.
  • Such an adapter which can already be connected directly in the prefabrication of the component, in particular, for example, an Ortbetondecke directly in the factory directly to the Ortbetondecke on the connection reinforcements, can directly form the basis for an adhesive bond.
  • an adhesive bond For example, it is possible to glue the foot of a railing to the front of the concrete head of the adapter.
  • the adhesive bond itself which is effected for example by an epoxy resin, has substantially the same or even a higher tensile strength, as the concrete of the adapter.
  • the connection reinforcement can be made of reinforcing steel, Stainless steel or fiber composites are produced.
  • the back of the adapter is designed by roughening or by a profiled shape so that the thrust forces between the adapter and the building, in particular z. As the Ortbetondecke can be transmitted.
  • the adapters which have reinforcing elements for connection to the actual concrete structure, are cast in directly during the production of, for example, an in-situ concrete floor. On site, the corresponding object can then be glued directly to the concrete head of the adapter without further processing.
  • an in-situ concrete floor 1 as a building or part of a building receives the front side of the adapter with the concrete head 10a.
  • connection reinforcement elements 20 which are poured in the production of the Ortbetondecke with.
  • the adapter acts as a lost formwork 10, which saves costs. Since the front surface 11 of the concrete head 10 a of the adapter is flat, this can immediately form the basis for an adhesive bond, for example, the foot of a railing.
  • the concrete head 10a of the adapter is traversed with individual fibers, as already in the DE 103 32 491 B4 is described. These fibers are non-woven distributed in the concrete, and ultimately provide for the high surface tensile strength of 15 - 25 N / m 2 .
  • the disclosure is explicitly based on the DE 103 32 491 Referenced.
  • the adapters are quite variable in size. That is, it is possible, for example, for in-situ concrete ceilings, prefabricate such adapters in a certain length with laterally diagonally opposite noses or projections 12 are provided, which overlap for connecting such adapters with each other. In the area of overlapping lugs 12, the connection of the adapters with each other also preferably takes place by means of an adhesive bond.
  • profiling 15 is provided between the concrete head 10a of the adapter and the Ortbetondecke 1 in order to transmit thrust forces in the direction of the arrow 17 can.
  • the profiling 15 is provided both on the concrete head 10 a and on the Ortbetondecke 1.
