Definitions

  • the invention relates to a shuttering element of the type explained in the preamble of claim 1 and a method for producing components using this shuttering element.
  • shuttering elements are used, for example, to shutter a first construction section before a second construction section is connected to the surface that has been shut off.
  • the difficulty here is that if the formwork is lost, the formwork element should not appear on the surface of the component perpendicular to the formwork element. So far, one has been helped by arranging a wooden strip in the area of the outwardly facing edges of the shuttering element on the outer formwork of the first or second construction section, which is then removed again, so that the remaining cavity can be filled with concrete.
  • this procedure is quite cumbersome and labor intensive.
  • the invention is therefore based on the object of creating a simple and inexpensive to handle shuttering element.
  • the tapering cross section according to claim 2 on the one hand creates a good connection both with the concrete part created in the first construction section and with the concrete part created in the second construction section. It also ensures that the surface of the concrete cover strip appears as little as possible on the surface of the component.
  • Claim 3 describes a particularly preferred cross-sectional design.
  • the design according to claim 4 on the one hand improves the fastening of the concrete cover strip to the formwork wall and, on the other hand, achieves effective corrosion protection for the component to be created.
  • Claims 6 and 7 describe a preferred material for the formwork wall.
  • the concrete cover strip can act as a spacer in order to keep the reinforcement in the intended position.
  • Claims 9 to 13 describe alternative fastening options for the concrete cover strip on the formwork wall.
  • the embodiment according to claim 14 on the one hand ensures good anchoring of the formwork wall in the concrete cover strip and on the other hand provides the concrete cover strip with a type of reinforcement.
  • Claims 15 and 16 describe particularly preferred methods for producing a concrete part with the shuttering element according to the invention.
  • a lost shuttering element 1 which comprises a formwork wall 2.
  • the formwork wall 2 consists of a flat panel 3 made of expanded metal, on the longitudinal bars 4 on one side and at predetermined intervals Cross bars 5 are welded on the other side lattice-like in such a way that they enclose the expanded metal sheet 3 between them.
  • a concrete cover strip 6 made of concrete is molded in such a way that the longitudinal bar 4 forming the free edge is embedded approximately centrally in the concrete cover strip 6.
  • the concrete cover strip 6 has an essentially flat surface 6a pointing in the direction of the formwork wall 2, which extends essentially perpendicular to the plane of the formwork wall 2.
  • the concrete cover strip 6 On the side opposite the flat surface 6a, the concrete cover strip 6 has a curved surface 6b, the transitions 6c between the curved surface 6b and the smooth surface 6a also being curved, so that there is an essentially parabolic to semicircular cross section of the concrete cover strip 6 results.
  • the transition regions 6c can also run in a straight line.
  • Fig. 2 shows the use of the shuttering element according to the invention for pulling in a ceiling consisting of several successively manufactured sections or components.
  • a formwork 8 is built up for the underside of the ceiling in a conventional manner.
  • a shuttering element 1 according to FIG. 1 is placed on the formwork 8 in such a way that the concrete cover strip 6 stands on the formwork 8.
  • the upper edge of the formwork wall 2 facing away from the concrete cover strip 6 is covered with a conventional concrete cover strip 9 made of wood.
  • Reinforcements 10, if necessary, are made of expanded metal Panel 3 butted, the smooth surface 6a of the concrete cover strip 6 also serves as a support surface and spacer for the lower reinforcement level.
  • one of the usual joint tapes 11 or a joint sheet can be attached to the shuttering element 1, if necessary with the aid of a joint tape basket.
  • the shuttering element 1 With its cross bars 5 facing the first construction section 7a, half of the concrete cover strip 6, the reinforcement 10 and half of the joint tape 11 are in concrete embedded.
  • the concrete also passes through the openings of the expanded metal of the panel 3, so that a good connection to the second, later to be built section 7b is achieved.
  • the upper concrete cover strip 9 is then removed, so that there is an offset joint at the top of the ceiling.
  • Fig. 3 shows a further embodiment of a shuttering element 1 ', as it is to be used for example to create a wall.
  • the shuttering element 1 ' differs from the shuttering element 1 according to FIG. 1 only in that two opposite edges of the Formwork wall 2 is embedded in a concrete cover strip 6 '.
  • the concrete cover strips 6 ' are arranged analogously to Fig. 1 so that their curved surfaces 6'b point away from the formwork wall 2', while their inner, smooth surfaces 6'a can in turn serve as contact surfaces for reinforcements, not shown, around these reinforcements in one to maintain a predetermined distance from the outer surfaces of the finished component.
  • FIG. 4 shows a further exemplary embodiment of a shuttering element 21, the same or comparable components being provided with the same reference symbols and not being explained again.
  • the shuttering element 21 in turn contains a formwork wall 2, which consists of cross and longitudinal bars 4, 5 welded to one another with the interposition of an expanded metal sheet 3, and a concrete cover strip 26.
  • the concrete cover strip 26 has a parabolic cross section with a flat and essentially facing the formwork wall 2 Surface 26a running perpendicular to the formwork wall 2.
  • the concrete cover strip 26 was made of fiber concrete extruded, in which a recess 27 which is open to the outside and extends essentially over the entire length of the concrete cover strip 26 was formed in the surface 26a.
  • the recess 27 is so wide and deep that a longitudinal bar 4 arranged on a free edge of the formwork wall 2 can be accommodated therein at some distance from the boundary surfaces of the recess 27. After inserting the formwork wall, the recess 27 is filled with grout or other suitable and hardening building materials, so that the formwork wall 2 is firmly connected to the concrete cover strip 26 after curing.
  • the shuttering element 21 can be used in the same way as the shuttering elements 1 or 1 '.
  • the formwork wall can consist of any other suitable formwork material, for example scale or waffle plate or an unreinforced expanded metal.
  • the shape of the concrete cover strips can be varied depending on the application. For example, a triangular, round or similar cross section is also conceivable.
  • the formwork wall can also e.g. be connected to the concrete cover strip by mechanical means.
  • the shuttering element according to the invention can also be used to manufacture a sole or the like.
