Definitions

  • the invention relates to a concrete formwork with at least two formwork panels, consisting of a main and transverse frame and a formwork panel fastened thereon, and with connecting elements for adjacent formwork panels, each having a displaceable profile beam, which has a wedge connection against the frame part of one formwork panel and a second the same type of wedge connection can be clamped to the frame of the adjacent formwork panels on the side facing away from the formwork panel, the wedge connections aligning the formwork panels automatically.
  • Such concrete formwork has the advantage over the formwork in which the adjacent main frame is connected by bolts or wedges (compare, for example, DT-AS 1 902 568, DT-OS 2 310 236, DT-OS 2 460 867), in that the wedge-shaped one
  • the deflection under load is only very slight, while in the directly connected formwork panels the torsion is subjected to torsion when the connection is loaded perpendicular to the formwork surface, which leads to large inadmissible deflections of the formwork under heavy loads.
  • Such concrete formwork of the type mentioned in the preamble of claim 1 is known from DE-OS 2 604 846 and DE-GMS 7 138 715.
  • U-shaped brackets are welded to the rear on the frame girders, into which the profile girder designed as a hollow profile can be inserted and clamped by means of a wedge piece with which the profile girder inserted into the bracket can be clamped.
  • the invention is based on the object, avoiding components protruding from the rear of the formwork panels, tensile and flexurally connected by means of the profile carrier which automatically aligns the panels.
  • the wedge sled accordingly engages behind the wedge-tightening surface of the wedge plate so that it can be accommodated in the space determined by the frame elements without having to protrude beyond the rear of the frame.
  • the underside of the wedge plate is aligned with the lower boundary surfaces or flanges of the transverse and longitudinal frame beams, so that the connecting profile beam can be braced directly with these wedge plates and the longitudinal beams, which either lie directly next to one another or also with spacers spaced apart can be braced against each other by the connecting device according to the invention.
  • the wedge slide is either provided with a head part projecting in the direction of insertion, which slides over the wedge plate, which is welded between the free legs of a cross bar with a U-shaped cross section.
  • the wedge tightening surface of the wedge slide can also be arranged within a closed ring forming the wedge slide, which is pushed over a wedge plate, which is welded to the main frame support and projects freely cantilevered in the direction parallel to the crossbars.
  • the profile beams can be provided with stop pieces in the form of a bolt or a weld nipple, which prevent the wedge slide from sliding off, so that the wedge slides are captively fixed on the profile beam.
  • stop pieces in the form of a bolt or a weld nipple, which prevent the wedge slide from sliding off, so that the wedge slides are captively fixed on the profile beam.
  • two such wedge slides are arranged on each profile beam, but it is also possible to provide three or more wedge slides for special connections, which cooperate with corresponding wedge plates of formwork panels or intermediate pieces or the like.
  • the wedge slides are preferably equipped on the side facing away from the wedge tightening surface with protruding cams which serve as a striking surface for driving in or releasing the wedge connection.
  • the formwork panels have a main frame 12 carrying the formwork plate 11 and crossbars 14 connecting the carriers of the main frame.
  • the crossbars 14 are partially formed in the embodiment of FIGS. 1 and 3 as U-profiles, the free legs of which have night ink, while in the embodiment of FIGS. 2 and 4 the crossbars 14a and the main frame are designed as a box profile.
  • the formwork panels are joined together in the manner shown in FIGS. 3 and 4 (or with the interposition of fitting pieces or fitting panels) in such a way that the main frame supports 12 of two adjacent formwork panels touch one another.
  • Wedge plates 18 are welded between the free legs 16 of the crossbars 14, which have a wedge surface 20 and, with their end 22 facing away from the wedge surface 20, bear against the main frame support 12 or are welded to it.
  • the underside 24 of the wedge plates is aligned with the plane formed by the back of the main frame support 12.
  • profile supports 26 with a box profile are provided, which rest against the back of the main frame supports 12 and the back 24 of the wedge plates 18 and, if appropriate, further cover plates 28 welded between the legs of the cross bar 14.
  • each wedge carriage has cam projections 38 which are used to actuate the wedge carriage with the hammer. By striking the cams 38, the wedge slide can be pulled up or released on the wedge plate.
  • the profile carriers 26 are provided with stops in the form of a pin 40 penetrating the box profile or a weld nipple 42, which prevent the wedge slides 30 from being pushed over the ends of the profile carriers 26 and detaching from them. In this way, the connecting elements remain connected as units to the wedge carriage.
  • the wedge plates 18a are next to a cross bar 14a by means of an angle piece 19 on a main frame support 12 welds such that, in turn, the back 24 is flush with the back of the carrier 12 in one plane.
  • the wedge slide 30a can be pushed onto these freely projecting wedge plate pieces 18a, which essentially consists of a closed ring which slides with its convex wedge tightening surface 34 on the wedge surface 20 of the wedge plate.
  • a steel sheet strip 45 is welded to the wedge plate 18a, so that the wedge slide 30a can basically remain in or on the formwork plate.
  • the wedge carriage In the assembled state, the wedge carriage is pushed onto the wedge plate and, in the storage or transport state, sunk into the formwork according to the drawing.
