Definitions

  • the invention relates to a reinforcement arrangement for embedding in a Masonry, according to the preamble of claim 1.
  • Masonry reinforcements are used for large-area walls, over window and door openings (as lintel reinforcement), at non-load-bearing partitions on sagging ceilings, in Pediment and mixed masonry. In general, it serves that Settling behavior of masonry wedges. Through vibration and Swelling processes can create tensile or compressive stresses, which exceed the elasticity of the masonry. So far not remedy here Expansion joints can or should be created in bed joints (horizontal longitudinal joints) embedded in the steel grid mortar bed, most of them made of parallel longitudinal bars connecting them Steel elements exist.
  • runner layer In the case of facing lintel reinforcement, there is a so-called runner layer, these are bricks, which in the bricked up state Long sides run parallel to the wall alignment, additionally a rolling layer in front of which the bricks are on the narrow side.
  • existing masonry occur tensile and Pressure forces on which the bricks are at their bottom Edges are moved apart, being in the underlying roll layer the upper brick edges pressed together and the lower Edges are pushed apart. This results in an the load-bearing layer is guided by force that is absorbed by tensile reinforcement is.
  • a reinforcement arrangement according to the preamble of claim 1 is known from DE 295 18 134 U, which is a reinforcement arrangement discloses, in the U-shaped bracket, the free leg ends of a horizontal crossbar are connected in the longitudinal bars of the reinforcement be attached, which presupposes that when installing the reinforcement first lay the longitudinal bars of the reinforcement in the mortar bed have to be in order to be able to hang the brackets.
  • brackets move into the longitudinal bars after they have been hung up the reinforcement cannot be supported on the stones of the stone layer, so the temples are not secured in place since the temples are not outside the angled sections of the surface formed by the bracket have, with which the bracket can be supported on the stones.
  • the reinforcement consists of both parallel longitudinal bars as well as from perpendicularly arranged, arcuate extending into the rotor layer and into the rolling layer Iron or plates, which are in the runner layer of the Lintel led bracket up to the neighboring parallel to the Stretch the longitudinal joint of the mortar or cement / mortar joint.
  • the Brackets can be releasably clamped to the longitudinal bars.
  • the temple ends hook-shaped; the brackets themselves are under tension clamped on the longitudinal bars of the reinforcement system.
  • DE 93 06 276 U describes a masonry interception device with a horizontal masonry reinforcement embedded in a wall joint in masonry mortar, via a vertically arranged connecting part can be connected to the masonry with a masonry anchor.
  • the masonry reinforcement made of parallel bars using cross bars connected longitudinal rods and transverse repositories and / or brackets with storage plates, at least one of the Support plates a vertical leg with a vertical as well threaded rod to the support plate for fastening a Has connecting part.
  • DE 44 38 437 A is a method and device for reinforcing Remove masonry through masonry openings.
  • the procedure for Reinforcement of clinker or masonry over window openings or the like, especially for the reinforcement of rolling layers with a wire or band-shaped reinforcement rail, fastened to the connecting elements that are fastened in the vertical mortar joints consists of that the rolling layer with the fasteners on an assembly support is bricked up in the masonry opening, after which the wire or band-shaped reinforcement bar over the Rolling layer is laid. Then the fasteners with the Reinforcement rail connected in a form-fitting manner.
  • the device to carry out this method is that the connecting elements are sheet-shaped and at least two Have retaining tabs that are bent during assembly and that thus overlap the reinforcement bar.
  • the known reinforcement arrangements or reinforcement systems are designed so that horizontal reinforcement bars are used, these are not fixed in their spacing, but after insertion into the mortar layer of a horizontal joint when attaching the stirrups or holding elements can move, if not special additional Measures are taken.
  • US-A-2,361,828 is masonry with embedded reinforcement known, wherein to produce a composite between Pressure and / or tensile zones of the facing lintel that bear pressure Anchoring system stones of the runner layer above the reinforcement form that the stones of a runner layer attached below the reinforcement stops.
  • the reinforcement consists of an horizontal mortar bed of the longitudinal joint above the runner layer embedded metal band or from at least one longitudinal rod and from placed on the metal strip or the longitudinal bar and from these worn brackets, which have their free ends in the mortar bed of the vertical joints of the runner layer below the reinforcement are led. If the reinforcement consists of a metal band or two or three longitudinal bars, then the two legs of each bracket connecting web on a length that the width of the metal strip or corresponds to the total width of the longitudinal bars.
  • EP-A-0 340 840 describes a reinforcement system for a wall masonry with a horizontal alarm to be inserted in the mortar bed, wherein vertical reinforcement elements are provided, which in vertical indentations or openings in the masonry are, the height or length of the vertical reinforcements about the height of at least two masonry stones lying one above the other equivalent.
  • the vertical reinforcements are at least arranged in a vertical direction on the horizontal reinforcement and with this firmly connected.
