Definitions

  • the invention relates to a formwork for concrete construction according to the preamble of claim 1 and to a method for producing this formwork.
  • Formwork elements are known, in particular also those for quiver formwork (DE-GM 90 01 890.7), which are produced from a formwork material which has a dovetail-shaped profile.
  • This formwork material which is designed as a flat material, preferably as a steel sheet with the profiling, has, among other things.
  • this also has the advantage of an improved integration in the concrete, so that if the formwork material remains in the concrete between two adjoining concrete components in the area of this formwork material, a transition that is significantly improved in static and dynamic terms is achieved.
  • the invention is based on the object, while maintaining the aforementioned advantages, form a formwork so that, if necessary, a simple and unproblematic connection of two ends of the formwork material is possible.
  • the formwork material is reshaped in the region of one of two ends to be connected to one another in such a way that the profile obtained after reshaping in the region of this end fits into the dovetail-shaped profile sections of the other end, i.e. a connection of the two ends is possible by placing these ends on or pushing them together.
  • the connection area the two ends overlap with the original, unchanged dovetail-shaped profile sections and with the reshaped profile sections.
  • the particularly advantageous dovetail-shaped profiling ultimately remains fully retained at least on one side of the formwork.
  • the reshaping is preferably selected so that the reshaped end can be pressed onto the non-reshaped end in a slightly clamping or push-button manner.
  • the reshaped profile is, for example, a triangular, trapezoidal or similar undercut-free profile, preferably an at least approximately rectangular or square profile.
  • the formwork according to the invention is preferably designed in such a way that the formwork material is angled or bent at least once or several times, in accordance with a crease line running perpendicular to the profile, with no bending being provided in the deformed area of the formwork material.
  • 1 is a formwork material which is formed by a plurality of strips 2 of a profiled steel sheet which are connected to one another.
  • the strips 2 are held or connected to one another at their longitudinal edges by specially shaped, form-fitting interlocking profile sections 3 and 4. Otherwise, the strips 2 are provided with a dovetail-shaped profile, ie each strip 2 has two dovetail-shaped profile sections 5 in the embodiment shown, which in the illustration selected for FIGS. 1-3 are provided over a plane E, in the area of which the profile sections 3 and 4 are provided protrude and extend in the longitudinal direction of the strips 2, ie parallel to the profile sections 3 and 4 and thus perpendicular to the plane of the drawing in FIGS. 1-3.
  • the profile sections 5 On its side remote from plane E, the profile sections 5 have a greater width a. In the area of plane E, the profile sections 5 have a smaller width b.
  • the space 6 between the profile sections 5 also forms a dovetail profile which is identical to the profile of the profile sections 5, i.e. has the greater width A in the area of the plane E and the smaller width b at a distance from this plane.
  • the formwork material 1 can easily be bent perpendicularly to the longitudinal extension of the strips 2 or the profile sections 5, in particular without the material being widened.
  • a length of formwork material 1 is used which has a total of four strips 2 connected to one another via the profile sections 3 and 4.
  • the formwork material is then bent at a total of four areas 8 perpendicular to the profiling, which is easily possible due to the dovetail profile, since the inclined sides of this profile can approach level E when buckling.
  • the profile of the formwork material is at one end of the blank 7', that is to say in the region of the end 9 there 2 reshaped such that the formwork material at this end 9 has a rectangular profile instead of the dovetail-shaped profile, with rectangular profile sections 10 where the profile sections 5 were originally provided, the rectangular profile sections 10 having a width b in plane E, which is approximately equal to the width b.
  • the spaces 11 between the profile sections have a width a 'which is approximately equal to the width a.
  • the formwork element 7 can preferably be supplied to the place of use by the manufacturer in the form of the blank 7 ′ with the end 9 already formed.
  • a shaping tool which consists of a stamp-like tool part 15 and a suitable die, is used to deform the end 9.
  • the forming tool 14 is designed so that the end of a strip 2 can be formed with it. For this purpose, the material is inserted between the two tool parts 15 and 16. Forming takes place by closing the tool.
  • the forming tool 14 is preferably designed at the same time as a cutting and punching tool, with which the material forming the formwork element 7 or the blank 7 ′ is cut or separated to the required length and openings for the fastening means 13 are punched.
  • the formwork material 1 is formed by a plurality of relatively narrow strips 2 which are connected to one another, the forces required for the forming tool 14 during forming are relatively small.
  • the formwork material 1 or the strips 2 each have openings 17 in the corners formed by the dovetail-shaped profile or in the corners of the profile sections 5, which in the longitudinal direction of the strips 2, ie in the axial direction perpendicular to the plane of FIG. 1 are provided in succession and have an effective cross section which is selected so that when concreting in the profile sections 5 or a part of these profile sections trapped air can escape, but a significant or disruptive passage of concrete at these openings 17 does not occur.
