Definitions

  • the invention relates to a flat steel anchor for masonry, the profiled on both side edges and with one imaginary straight line running along the flat steel anchor outward, laterally outward projections and is provided inward recesses, the Projections and the recesses congruent and of wave or zigzag lines are limited in the Way that the flat steel anchor seen in the floor plan- or is designed zigzag and a recess on the one side of the flat steel anchor a projection on the opposite side of the flat steel anchor.
  • the invention further relates to a method for manufacturing this flat steel anchor.
  • Such anchors are used for masonry made of sand-lime brick, Gas concrete blocks, gas concrete blocks or similar stones used, placed flat between these stones and in thin bed mortar, light mortar or similar binder or Adhesives held. They are mostly on the move stressed and must therefore be well fixed so that they the Can fulfill anchor effect.
  • Air layer anchors are also known (GB-A-2259532) are designed like a W at both ends of the floor plan, in such a way that individual anchors from one Material web without material waste by shearing, punching or. Like. Can be obtained.
  • the anchor blank is laterally separated by two parallel straight lines limited.
  • the middle section shaped in this way of the anchor blank is used to produce the finished product a place deformed by twisting to get there in the built Condition of the anchor in the area of the air layer between the to drain both shells of the masonry and a holder for that to be installed in the air layer Form insulation material.
  • the flat steel anchor known from GB-A-2 259 532 has the features of the preamble of claim 1.
  • the invention is based on the object at the outset to improve the flat steel anchor mentioned so that on Edge punching is dispensed with, but still an edge profile can be achieved, the good pull-out strength guaranteed. Waste of materials should therefore be excluded become.
  • the invention proposes using the flat steel anchor as an anchor for butt joints in masonry one extending over the entire anchor length, to form edge profiling on both sides.
  • the anchor according to the invention consists in that the known flat steel anchors with a distance from each other arranged U-shaped incisions are now essential easier manufacture is possible. Because of the invention the individual bottle steel anchors are replaced by one if necessary material web that can be pulled off a roll by a transverse wavy or zigzag Cut separated, this cut through Scissors, punching or the like can be carried out. The so obtained flat steel anchors obtained by such Manufacture your desired edge profile so that the required pull-out strength can be achieved.
  • the invention does not exclude that the flat steel anchor also with small holes or openings and also with Depressions can be provided.
  • the necessary Operations can be done along with the manipulations be carried out with which the flat steel anchor from the Material web is separated.
  • the material web mentioned, from which the flat steel anchors separated can have a width that is the length of a Flat steel anchor corresponds, but it is also possible widths to choose which is double, triple or the like, that is Multiple times an anchor length.
  • the parallel longitudinal edges 6 are designed or based on the invention in a special way profiled to fix the flat steel anchor in the joints 4 to improve.
  • the improved fixation also serve in a series of shallow depressions 7 arranged approximately have a triangular floor plan. They are in every half located depressions 7 so that their tips 8th point in the same direction, while the tips 8 of all Indentations 7 to the center of the anchor at 10 point.
  • This shape has the advantage of improved mounting of each half of the Flat steel anchors 5.
  • can also in the Anchor center at 10 is a square or similar shape Depression 7 are located.
  • the longitudinal edges 6 are weak designed in a zigzag shape, they extend over the entire anchor length and are also on both sides of the flat steel anchor.
  • the edge profiling is made by an imaginary, longitudinal to Anchor straight line 11 determined.
  • the distance between them Straight line 11 on the side corresponds to the nominal width or the active width B of the flat steel anchor.
  • the body of the flat steel anchor 5 runs overall zigzag, since the neighboring ones, on opposite Edge parts 12, 13 located parallel to the armature to each other. Since the straight line 11 has the edge parts 12, 13 halved, result from the straight line 11 outwards extending projections 14 (shown hatched) in Triangular shape and also shown hatched Recesses 15 in a triangular shape.
  • triangles or protrusions 14 and recesses 15 match the shape and size after congruent, but with the peaks in opposite directions - transverse to the longitudinal direction of the anchor - demonstrate.
  • the mass d therefore coincide; the length L is that Double dimension of the triangles 14, 15.
  • the dimension d be about 2-4 mm; the dimension L can be around 5 - 10 cm to get voted.
  • the side edges 6 run continuously roughly along a sine line; the mass s are then Amplitudes, while the measure L determines the vibration range.
  • FIG. 9 shows one compared to FIG. 5 reduced zigzag division. But here, too, the two Side edges 6 designed so that the bottom 16 a recess 15 of the most protruding point 17 of the Projections 14 is exactly opposite.
  • a particular advantage of the invention is that the Manufacture of the individual flat steel anchors by separating a material web 18 can also happen, which also has a winding 19 can form so as to pull off the material web 18 from this can.
  • the individual flat steel anchors 5 are cut off by cutting, punching or the like. With the separation the Flat steel anchor its final, waste-free shape conveys, so already the special profile of the Side edges 6. This is possible because the sizes of the Divisions and the projections or recesses (areas at 14 and 15) are all coordinated.
  • the depressions 7 and the holes 9 can together with the Separation of the individual flat steel anchors 5 from the material web 18 are generated.
