Definitions

  • the object of the invention is a wall reinforcing strip for use in the construction industry, which wall reinforcing strip is a perforated metal strip, where perforations cover 20 to 80%, preferably 40% of the surface area of the metal strip, and the thickness/width ratio of the metal strip is maximum 1/30, preferably 1/100.
  • Utility model No. U0500157 discloses a metal strip reel, where the metal strip has projections.
  • the metal strip has several coils, and a retaining device securing the reel against unwinding at the free end, which forms a releasable connection between a first point close to the free end of the metal strip and a second point in a metal strip segment, which is part of a different coil, or a point on the spool.
  • the formed connection is a shape-mated connection, where the retaining device comprises two spatially separated functional ends, the first end comprises a lug ring, which snugly accommodates the entire width of the metal strip and catches a projection of a first coil of the metal strip.
  • the second end of the retaining device comprises a hook, which latches into a second projection of a second coil of the metal strip.
  • the product according to the model is for use mainly in packaging equipment.
  • the aim of the invention is to provide an alternative solution multiplying the advantageous effects of soft-iron wire wall reinforcement, minimizing the potential for errors as a result of the simpler technology, and having other advantageous characteristics: because of its strip form it has high transverse stability in itself, therefore prestressing is not required, due to its featured surface it is fixed well in the mortar even without nailing or dowelling, and the large material cross-section achievable with a thin design results in an extreme load-carrying capacity, allowing multi-purpose application (partition wall reinforcement, application as a joining element in junctions, and the reinforcement of load-bearing wall sections carrying different loads). It is simple to use as a joining element in junctions, it ensures a very stable connection between the wall elements.
  • the invention is based on the recognition that the resulting stability of sandwich structures made of materials having different properties is better than that of the components separately.
  • the tensile and bending strength of traditional wall materials is far lower than their other properties (e.g. compressive strength), on the other hand metal strips have good tensile loadability as well.
  • a typical sandwich structure is composed of two layers capable of withstanding high tensile forces, and a core of high compressive strength embedded between them. In walls constructed this way bending in the vertical direction due to non-uniform load changes into a tensile force at points further away from the force, which is easily bearable for both a strip and a properly sized stressed wire.
  • the wall reinforcing strip according to the invention significantly increases the stability of walls because:
  • the wall reinforcing strip is especially suitable for this task because it can be well embedded in any type of mortar and adhesive, it is highly resistant to tensile and shear forces, thereby it allows the formation of a stable connection between the wall elements.
  • the object of the invention is a wall reinforcing strip, which is a perforated metal strip, where perforations cover 20 to 80%, preferably 40% of the surface area of the metal strip, and the thickness/width ratio of the metal strip is maximum 1/30, preferably 1/100.
  • the perforations can be of any shape, e.g. circle, oval, square, rectangle, but preferably they are circle-shaped.
  • the size of the perforations can be varying, e.g. for circle-shaped perforations the perforations can be of different diameters.
  • the location of the perforations on the metal strip is arbitrary, it can be asymmetric or symmetric, but preferably the location of the perforations is symmetric.
  • the material of the metal strip is preferably surface-treated high strength steel plate.
  • the two edges of the metal strip are equipped with toothings, the teeth are preferably at equal distances from each other, furthermore the perforations are uniformly distributed and arranged in rows on the metal strip.
  • the size of the perforations is preferably the same by row.
  • the location of the rows is symmetric, with the proviso that one row is along the axis of symmetry of the metal strip.
  • the number of rows of perforations on the wall reinforcing strip is three, and the rows are arranged in such a way that the diameter of the middle row of perforations located along the axis of symmetry of the wall reinforcing strip is smaller than the diameter of the perforations of the outer rows.
  • the two edges of the metal strip are equipped with toothings.
  • the perforations and toothings are axially symmetric and the number of axes of symmetry is two by repeated pattern unit, furthermore rows of different perforations are shifted symmetrically compared to each other in such a way that the perforations of rows of larger perforations are in line with each other and the perforations of the middle row are in line with the teeth of the toothings.
  • the smallest widths of the plate parts remaining between the perforations of the middle perforated row and the nearest larger perforations are equal, as the proper strength/load-carrying capacity of the wall reinforcing strip can be ensured only this way.
  • the smallest distances between the adjacent perforations in any direction and the distances of the perforations of the two larger perforated rows from the edges of the metal strip are equal.
  • FIG. 1 shows a top view of an embodiment of the wall reinforcing strip according to the invention.
  • the perforations on the metal strip 1 are arranged in three rows 2 in such a way that a row 2 of smaller diameter is in the middle, along the axis of symmetry 4 of the metal strip 1, and two rows 2 of larger diameter are on the two sides of the middle row 2.
  • the edges of the metal strip 1 are equipped with toothings 3, the distances between the teeth are the same. It can be seen that the perforations and the toothings 3 are axially symmetric and the number of axes of symmetry is two by repeated pattern unit.
  • the rows 2 of different perforations are shifted symmetrically compared to each other in such a way that the perforations of rows 2 of larger perforations are in line with each other and the perforations of the middle row 2 are in line with the teeth of the toothings 3. From the point of view of the strength of the wall reinforcing strip the location of the perforations compared to each other is important. Therefore the smallest widths of the plate parts remaining between the perforations of the middle perforated row 2 and the nearest larger perforations are equal. The distances of the perforations of the two larger perforated rows 2 from each other and from the edges of the metal strip 1 are also equal.
  • the wall reinforcing strip is laid on a binding material applied to the appropriate wall part.
  • the binding force between the wall elements is not reduced, at the same time the wall reinforcing strip is embedded in a stable manner.
  • the thickness of the invention allows application in a very thin (even 1 to 2 mm) layer of adhesive mortar as well.
  • the toothings 3 of the edges of the metal strip 1 prevent the slipping of the joint, even if there is not enough binding material on the surface of the wall reinforcing strip, or the made interstice is too narrow.
  • the middle row 2 of smaller diameter allows fixing either with wire, by nailing or screwing. Any traditional plate shears are suitable for cutting the wall reinforcing strip.
  • the wall reinforcing strip according to the invention is the reinforcement of wall junctions, the ensuring of a stable connection between wall elements, then preferably a piece of wall reinforcing strip shall be placed in each row of the connecting wall in such a way that it is embedded in both walls to an appropriate depth (min. 2/3 rd of the wall thickness).
  • a wall reinforcing strip made of surface-treated high strength steel plate can withstand a tensile force of minimum 5000 N (a load-carrying capacity of about 1 ⁇ 2 ton), this roughly corresponds to the performance of a 4 mm thick soft-iron wire.
  • the wall reinforcing strip shall be applied in the whole structure, in a bearing wall of average size even 2 to 3, or more wall reinforcing strips per row shall be placed between the wall elements beside each other in parallel. For such purposes the application of wall reinforcing strips with increased load-carrying capacity may be justified.
  • the product according to the invention can be used as a traditional suspension strip, as the middle perforated row 2 allows fixing with wire, or by nailing, and the structural design of the invention facilitates bending without breaking, and allows screwing.
  • the product according to the invention can also be applied embedded directly in the adhesive under floor tiles, with its use the breaking of floor tiles mainly above expansion gaps and foundation cracks can be prevented.
  • the product according to the invention is in the form of a reel before use, thus its delivery and storage is simple and requires little space.
  • the wall reinforcing strip according to the invention is an important addition to walls constructed of traditional wall materials, applied in a sandwich structure it significantly increases the stability of walls, and as a junction element it joins the connecting walls to each other in a stable manner.
