Definitions
- the invention relates to a method for adhesive bonding a band-shaped tension member with a concrete surface by means of a between the concrete surface and the band-shaped Tension member applied adhesive layer.
- an adhesive composite can be chosen, which itself has certain deformability, i.e. a high one Deformation module has, so that a crack opening Expansion compensation in the tension member take place over a length can, which is significantly larger than the increase in crack width.
- Such adhesive composite materials with a high deformation modulus are but because of the creep loss associated with it Permanent anchoring unsuitable.
- the tensile forces must emerge from the tension member via the adhesive layer led out and introduced into the concrete body. This is done via shear stresses in the adhesive layer, that are associated with thrust distortion. This Thrust distortions do not only depend on the thrust module of the Adhesive material, but also on its layer thickness.
- the object of the invention is therefore a method of to train the genus mentioned at the outset so that a defined one Low creep adhesive bond between the band-shaped Tension member and the concrete surface using an adhesive layer is achieved, the layer thickness can be specified precisely and does not change uncontrollably even during the pressing process.
- This grid pattern preferably by a between the Concrete surface and the band-shaped tension member inserted Lattice web is formed, which is for example a fabric, serves as a spacer between the concrete surface and the band-shaped tension member, so that a defined layer thickness can be achieved and maintained.
- the use of the grid pattern leads to the fact that the bond between the concrete surface and the band-shaped tension member essentially only in the area of Lattice openings take place, the choice of Number and width of the grid openings to the adhesive surface can adapt special adhesive properties.
- the adhesive layer is through the mesh reinforced; the entrainment effect of the fabric length Thrust distortion forced. This leads to an equalization the shear stresses and thus the adhesive stresses at the interfaces.
- the grid web is preferably flexible.
- Tissue has proven to be particularly beneficial to fiberglass highlighted because it is highly flexible and corrosion resistant has a high tensile strength.
- the grid web is a perforated sheet or a perforated film.
- the grid path can be shaped with the surface of the band Tension member connected.
- the lattice web preferably the perforated plate or the perforated film, with the bottom of the band-shaped tension member glued, welded or through Melting is connected.
- the grid by profiling the underside of the band-shaped tension member is formed so that a rib or nub-like surface structure arises, whereby the Ribs or knobs serve as spacers.
- a band-shaped tension member 3 is glued on to a concrete body 2, for example from steel lamellas or from carbon fibers reinforced plastic tape.
- the fabric 6 forms a lattice web acting as a spacer between the concrete surface 1 and the band-shaped tension member 3, which ensures that when the underside 4 of the band-shaped tension member 3 provided with the adhesive layer 5 is pressed against the concrete surface 1, a predetermined layer thickness d is maintained.
- stamps consisting of the adhesive material are formed between adjacent fabric threads 6a of the fabric 6, the lateral dimensions of which are determined by the mesh size of the fabric 6 and the height of the layer thickness given by the fabric 6 d corresponds.
- a glass fiber fabric with a thickness of approx. 0.5-1 mm and a mesh size of approx. 2-4 mm are used.
- the Gluing is essentially only in the mesh effective.
- FIG. 2 illustrated embodiment differs from that previously described embodiment essentially characterized in that as a grid path to form the grid Perforated plate 7 between the concrete surface 1 and the underside 4 of the band-shaped tension member 3 is inserted.
- Perforated sheet 7 can also be used a perforated film.
- the adhesive layer 5 is formed in the holes of the perforated plate 7 in the holes of the perforated plate 7 are also "stamps" 5a the adhesive layer 5 is formed.
- the perforated plate 7 or the perforated film can with the underside 4 the band-shaped tension member 3 connected before the gluing process be, for example by gluing, welding or by Melting.
- the embodiment according to FIG. 4 differs from this in that the grid pattern in the area of the adhesive layer 5 is formed in that the underside 4 'of the band-shaped Tension member 3 is profiled and ribs 8, for example has, which come to rest on the concrete surface 1 and between which the "stamp" 5a of the adhesive layer 5 are trained.
- the ductility of the adhesive connection preferably a CBC adhesive connection so increased that one for the Force transmission from the band-shaped tension member and for the Force transmission into the concrete surface 1 cheaper Shear stress curve is reached.
- the Deformability of the adhesive material increased without, however to negatively influence the creep behavior.
