Definitions

  • the invention relates to a reinforcement bar, in particular for thermal insulation Power transmission between two components, preferably made of concrete serves, the reinforcement bar consists of fiber-reinforced plastic.
  • rebars are, for example, together with one of the reinforcing bars traversed insulator used in component joints in addition to a power transmission to achieve adequate thermal insulation.
  • plastic reinforcement bars cf. WO / 9702393 A
  • reinforcements have been made in the past Investigations carried out to find an alternative for certain applications in addition to the conventional metal bars made of reinforcing steel or stainless steel to accomplish.
  • a major incentive for tests with plastic reinforcement bars lies in the lower thermal conductivity of certain plastics (e.g. polyester, Vinyl esters etc.); different types of fibers such as glass, Aramid and other fibers the tensile strength and thus the stability of the reinforcing bar adapt very precisely to the respective application.
  • a major problem of the known plastic rods is that they are in the joint area between two concrete components according to the usual stainless steel rods installed there are corrosion-resistant, however the fibers used in the areas impacted by the concrete through there prevailing alkaline milieu attacked, so that it thereby their power-transmitting Can no longer perform the function completely.
  • the plastics used as the hard matrix of the tension rods are usually a has a certain potential for microcracks, which can occur with additional tensile stress develop into macro cracks.
  • the hard matrix loses due to these macro cracks against the reinforcing fibers their protective function, so that, for example, in Alkaline water present in concrete has access to the fiber surface and there can have a destructive or corrosive effect.
  • reinforcement bars with reinforcing fibers made of E-glass and aramid are still in use Construction have not yet found any significant application.
  • the present invention is based on the object To provide reinforcement bar made of plastic material, which is reinforced by Resistance to alkaline media found in concrete and mortar distinguished.
  • the reinforcement bar has a metallic sheathing on the outside, which is closed over the Outside and the fiber-reinforced plastic compared to the environment shields against diffusion. So the metallic covering acts as a protective layer, so that the fiber-reinforced plastic in terms of its static and Thermal insulation properties can be selected without changing the chemical To put resilience in the foreground.
  • This metallic envelope can for example consist of a metal foil and in particular consist of a stainless steel foil, whereby even the smallest foil thicknesses are sufficient can to prevent the penetration of alkaline media, which at the same time, due to the low film thickness, the thermal conductivity is not essential is significant or already has very good values for a stainless steel foil.
  • the main advantage of a metallic coating comes into play when the metallic envelope forms a lost shape, which is in the manufacture of the Reinforcing bar is used, for example, before casting the reinforcing bar placed in the mold, then with the fiber-reinforced plastic material filled and connected to it immediately.
  • the Metallic cladding can also be used as a shaping during a pultrusion process Serve wrapping or form or formwork.
  • the advantage of such procedures lies in the fact that "wet on wet" is an intimate bond between the matrix material (Synthetic resin) and the outer metallic covering can be produced.
  • the metallic casing from a Coating exists which is either the mold for the fiber reinforced plastic acted upon and after grouting on the outside of the reinforcing bar is set, or the plastic reinforcement bar after its manufacture applied.
  • the covering made of a metallic material with low thermal conductivity, in particular is made of stainless steel. This ensures that the Low thermal conductivity is not an advantage of the plastic reinforcement bars is significantly impaired, since otherwise it is also made entirely of metal could use manufactured rods.
  • the wrapper should also be made of a corrosion resistant Material are made to make the plastic rebar permanent to protect against the alkaline environment of the concrete.
  • An advantageous coating method is to make the reinforcement bar electrostatic charge and pass through a powder swirl chamber, taking due to the electrostatic charge, the epoxy resin powder particles on the rod surface can deposit. Then the bars are charged by a Oven section, and the epoxy resin particles are caused by heat from the outside melted inside.
  • the cylindrical plastic reinforcement bar 1 shown in Figure 1 consists of a Plastic or synthetic resin as matrix material 2 and approximately parallel to the rod axis extending reinforcement fibers 3, for example made of glass fibers, aramid fibers and the like can exist.
  • reinforcement fibers for example made of glass fibers, aramid fibers and the like can exist.
  • the metallic sheathing 4 is tubular or tubular design without longitudinal seam.
  • Such a longitudinal seam connection 15 of an envelope 14 is shown in FIG. 2, where it can also be seen that the longitudinal seam connection selected there consists of an adhesive or There is a welded joint, which is selected so that it produces a complete tightness and mechanical strength guaranteed. Otherwise, the reinforcing bar 11 shown in FIG. 2 corresponds to the reinforcing bar 1 from FIG. 1.
  • the present invention offers the advantage that with the same mechanical properties of known plastic reinforcement bars a safe Tightness against alkaline media can be created, which the accordingly covered reinforcing bars are also permanently installed in concrete components can be.
