Definitions

  • the invention relates to a slab formwork with horizontally arranged in the use position, rectangular, edge webs having formwork panels and with support means for these formwork panels and with a contacting in the use position edge webs of adjacent formwork panels in a corner of the formwork panels detecting holding element.
  • Slab formwork is known in many forms.
  • a slab formwork in which a holding element is provided to detect the four corners of four colliding in these four corners formwork panels simultaneously.
  • undercuts are arranged in a longitudinal direction, which are taken up by specially shaped webs of the formwork panels in the position of use, which requires very special formwork panels.
  • the ceiling defined above is Formwork characterized in that the holding element has centering projections for the edge webs of the formwork panels and between the centering in the use position horizontally extending, intersecting, upwardly open passage openings are provided which are bounded by lateral centering surfaces of the centering, and that the lateral boundaries or centering surfaces of the through holes from top to bottom approach each other at least to a mutual distance corresponding to the total thickness of two in the position of use touching edge webs of two formwork panels.
  • the holding element can grip and connect the four corners of four panels without the need for undercutting.
  • the formwork panels can be easily placed from above with their corner regions on the support member, each detected a centering formed by two edge webs edge of a formwork panel and engages in this corner, as each two in the corner in use position abutting edge webs fit between the centering , Since the centering projections have corresponding centering surfaces, the formwork panels are automatically positioned correctly by the assembly, since the abutting formwork panels center each other as they fall into the position of use on the holding element by the centering surfaces and their distance and position. In this case, the respective outer sides of the edge webs, for example, four formwork panels automatically come to mutual contact, between them an approximately scarf-shaped parting line is formed, but so narrow that virtually no concrete can penetrate.
  • the centering projections are arranged on a plate which supports the horizontal through-holes. Openings closes down and serves as a support for the formwork facing away from the edges of the edge webs of the formwork panels in the use position. Although the upper end faces of the centering projections could also support the formwork panels on the underside of the formwork skin, this might not result in a sufficiently stable power transmission.
  • the centering projections having plate for supporting the edge webs, there is a good introduction of the forces occurring during concreting.
  • the centering projections are only dimensioned so high that they do not or hardly touch the outside of the formwork skin.
  • a particularly advantageous embodiment of the invention can provide that the centering of the centering projections at the location of their closest approach in vertical boundaries of groove-like spaces between the centering pass over whose inside width of the thickness of two adjacent edge webs corresponds, wherein the groove-like spaces in the lower use position form the passage openings.
  • the formwork edge edges can be positively embraced over a certain width of the through holes and thus be set even better.
  • a good fit between the formwork panels and the holding element with its Zentriervorsprüngen are especially in the horizontal direction.
  • the formwork panels can slide during assembly with the edge webs along the centering projections and then enter into the groove-like interstices, so that they have a stable and defined position, especially after the assembly of all four supported on such a holding element formwork panels, in which the Schalphaseute these formwork panels are due to the coincidence of the dimension of the edge webs in a matching plane.
  • at least a portion of the edge webs of the formwork panels can be held in a sliding or clamping fit in the passage opening receiving them and their groove-like spaces.
  • a sliding seat has the advantage of slightly greater tolerance, a clamping fit the greater stability of the mutual fixing.
  • each centering projection in the corner of a formwork panel act on the perpendicular to each other to this corner extending edge webs and thereby not only support the four formwork panels in the desired manner, but also hold together.
  • the insertion of the formwork panels is favored because the centering projections can taper upwards in the region of their centering surfaces and in the region of the transition surfaces arranged between the two centering surfaces of a centering projection.
  • All centering projections may have a matching shape and matching dimensions and each adjacent centering projections may each be rotated by 90 ° to each other, in the position of use directed upward, be arranged.
  • the centering projections in each case match the corners formed by edge webs of formwork panels and it is not necessary in each case to assign a specific formwork panel to a specific centering projection.
  • Between two centering of a centering projection may be provided on the approximately the center of the holding member side facing a connecting surface which is flat or spherical and leaves in the use position, the inner edge of the corner edge formed by two edge webs acting on this centering projection board.
  • this results in material savings on the centering projections and, on the other hand, also facilitates the laying on of the formwork panels in which possibly the corner region of the edge webs could be somewhat rounded.
  • centering surfaces could also be flat, curved or spherical and also the cross section of the centering surfaces parallel to the formwork panels or to the holding plate could be straight or curved.
