Definitions

  • the invention relates to masonry reinforcement according to the Preamble of claim 1.
  • Masonry reinforcements are used for large areas Walls, over window and door openings (as lintel reinforcement), with non-load-bearing partitions sagging ceilings, in the gable masonry and in the mixed masonry. In general, it serves the setting behavior of To collect masonry parts. Through shrinkage and swelling processes tensile or compressive stresses can arise, which exceed the elasticity of the masonry. So far here cannot be remedied by expansion joints or should be in bed joints (horizontal longitudinal joints) embedded in the mortar bed steel grid that mostly made parallel longitudinal bars with other connecting them Steel elements exist.
  • runner layer In the case of facing lintel reinforcement, there is a so-called runner layer, these are bricks, in the bricked state the long side runs parallel to the wall alignment, still a grenadier layer in front of which the bricks on the Stand narrow side. Grenadier and The existing layer of masonry is subjected to tensile and compressive forces on which the bricks at their lower Edges are moved apart, being in the one below Rolling layer pressed the top edges of the brick together and pushed the bottom edges apart will. This results in a load-bearing Shift-directed force that is absorbed by tensile reinforcement is.
  • Masonry reinforcement is considered by the in the generic term EP-A-0 603 517 known.
  • the one described there Masonry provides that to make a composite between the pressure and tension zones of the facing lintel Pressure-bearing stones of the runner layer above the reinforcement form an anchoring system that is below the reinforcement attached stones of the rolling layer to hold brings, the reinforcement both from parallel Longitudinal bars as well as from perpendicularly arranged, extending into the rotor layer and the rolling layer there is an arcuate bracket or plate, wherein led into the runner layer of the facing lintel Bracket up to the adjacent one parallel to the longitudinal joint Spread mortar or cement / mortar joint.
  • the pressure-bearing stones over the reinforcement include an anchoring system that the under the Reinforcement attached stones stops, so that a better distribution of the pressure and / or tensile forces at the same time avoiding sagging of the masonry is achieved in the facing lintel, being unconnected Reinforcing bars used for the anchoring system the distance between them cannot be changed during assembly is set.
  • the reinforcement consists of at least two individual reinforcement bars running parallel to each other, at least one connecting the reinforcing bars with each other and in Spacers and at least one perpendicular arranged to the reinforcing bars, in the Mortar joints of the individual layers of the masonry Bracket, being used to produce a composite between pressure and / or tension zones of the composite lintel, in which the pressure-bearing stones of the runner layer above the Reinforcement form an anchoring system that below the Reinforced stones of the grenadier layer to hold brings the reinforcement from both the parallel, unconnected reinforcement bars as well as perpendicular to it arranged, either in the runner layer and / or in supports extending the grenadier layer, e.g.
