Definitions

  • This invention relates to the crack-bridging protection of new or crack-bridging Repair of existing crack-prone reinforced concrete or steel composite components.
  • Independently from the static system is the according to DIN 1045 and the notebooks 525 and 526 of Durability and stability required by the German Committee for Reinforced Concrete Reinforced concrete or steel composite structures guaranteed by this invention.
  • DIN 1045 Independently from the static system is the according to DIN 1045 and the notebooks 525 and 526 of Durability and stability required by the German Committee for Reinforced Concrete Reinforced concrete or steel composite structures guaranteed by this invention.
  • Of the Protection against the entry of concrete attacking (carbonation etc.) or corrosive (Tausalze, seawater, etc.) substances in the reinforced concrete or steel composite construction Parking garages, underground garages, floor slabs, flat roofs, etc. are thus ensured.
  • the goal of protective measures is to increase the resistance of concrete components against the penetration of concrete attacking or corrosive substances and against mechanical effects on near-surface areas to ensure a required Useful life of 50 years.
  • For the protection and in the given case the repair of concrete come to ensure the durability of the structure after sufficient Preparation of the concrete substrate in principle next to the crack-filling and reprofiling Measures of the order of surface protection systems, mainly Crack-bridging systems.
  • binders are usually in these systems two-component, cold-curing reaction resins (epoxy resins, polyurethane-modified Epoxy resins, polyurethanes, etc.) used.
  • Such coatings are significantly, extensive requirements.
  • the main required properties are on the one hand high abrasion resistance and high chemical resistance and on the other hand good Crack bridging capability even under dynamic conditions.
  • seals can also be used in accordance with ZTV ING, Part 7 Sections 1 to 3.
  • the crack bridging becomes ensured in these systems by welding tracks or liquid plastics.
  • the mechanical Resistance ensures a protective layer of cast or rolled asphalt.
  • a reinforced concrete component in which it is In particular od a parking garage door.
  • Can act with at least one reinforced concrete Einfeldplatte and with at least one beam, which is characterized that the at least one Stehlbeton Einfeldplatte at the gates to the at least a sub-structure articulated by waiving the upper reinforcement and that each Unterzugseite a joint is provided perpendicular to the main tensile stresses.
  • the at least a reinforced concrete single-span plate a diagonal, anchored in the beam suspension on.
  • the invention can also Hoesch additive blankets (as an example of a steel composite construction) be applied (see Figure 2).
  • a reinforced concrete single-plate which at the gates to the beams is hinged up.
  • the absorption of the lateral forces is carried out by an oblique and Longitudinal reinforcement, which connects the plate with the beams frictionally.
  • the plate is a Fugenterrorism, which is resistant to the ingress of chlorides etc. protected by the method described.
  • the location of the crack site through the concrete joint can be specified with a specific cut per unit side. This will make the system very economical, as the field areas remain unscheduled, and thus no need further protection.
  • the usual upper reinforcement is dispensed with, and replaced by a diagonal suspension bracket anchored in the beam is.
  • both lateral forces and normal forces can be transmitted in the concrete joint.
  • the crack width results in bending from the Tangentenverfitung the Einfeldplatte and at train from the elongation of the lower reinforcement and is determined by the method described permanently protected.
  • the system can also be used for the protection of reinforced floor slabs (Figure 4).
  • section A is the (possibly only there existing) upper and sever the (continuous) lower reinforcement.
  • section B In the standard areas, the bottom reinforcement (section B) not cut. Thus, a Aufschdorfln the bottom plate avoided in area A.
