Definitions

  • the invention relates to a concreting panel, which offers a formwork surface with its front side.
  • a particularly widespread type of concreting board is the so-called frame formwork.
  • a frame formwork usually consists of a rectangular frame of metallic beams, which is further stiffened by running in the longitudinal and / or transverse direction intermediate support, and a frame connected to the formwork, typically from a plywood. The mentioned carriers are welded together.
  • the supporting function or support structure of the formwork panel is essentially taken over or formed by the possibly stiffened frame, whereas the formwork skin forms the formwork surface with its one side, without substantially assuming support function.
  • the known frame formworks have a comparatively high weight per square meter of formwork surface. Since framing in different formats are required at the construction, these different formats must be delivered to the construction site in at least the required number and stored there until they are used. As a result, the logistics are elaborate, which is especially true for less popular formats.
  • the manufacturer of the frame formwork shows similar difficulties. In particular, a considerable number of different frame formwork formats must be manufactured in different ways.
  • the invention has for its object to make a concreting board available that can be produced more efficiently in different formats.
  • the formwork panel according to the invention is also damaged easier to repair than conventional frame formwork, be it at the construction site or at the factory.
  • Many embodiments of the formwork panel according to the invention have the potential to be more economical and easier per square meter of formwork area than conventional formworks.
  • a concreting panel with the features of the preamble of claim 1 is both of CH 679 230 A5 as well as out JP 6 212785 A known.
  • CH 679 230 A5 Nothing is said about how the local plastic sheathing boards are connected to the frame of the board.
  • JP 6 212785 A the plastic filling elements are nailed to the edge supports.

  • the edge girders are longer than the filler members (having a length perpendicular to the two girders) so that the girders bridge the longer longitudinal dimension of the formwork panel and the filler elements bridge the shorter transverse dimension of the formwork panel.
  • the filling elements must absorb so far only a lower bending moment between the first and the second end of their length than the edge support, which is why preferably the edge support are designed so that they can absorb a higher bending moment than the filling elements.
  • marginal beams which are shorter than the filling elements, especially for less frequently occurring formats.
  • the filling elements are connected by means of mechanical connecting elements with the two edge beams, wherein in claim 1 screws, rivets or clamping elements are specified.

  • the two edge supports and the filling elements all have substantially the same height. This leads to optimum material utilization and good stackability of the formwork panels.
  • the two edge beams each have a cross section in the manner of a double-T profile.
  • Double-T profiles have a particularly good material utilization. It is in the hand, the two flanges of the profile in their material thickness and in their width in such a way that the profile has the desired moment of resistance to bending. In some training cases, it is a convenient way to form the middle web of the profile as a hollow web, so that the cross section of the profile is closer to a rectangle, possibly with a widened head and widened foot.
  • the two edge supports are each formed on their side facing the filling elements with a longitudinal projection, which is designed for the bottom engagement with a connection lock for connecting two adjacent formwork panels.

  • the half-hole is supplemented by a corresponding half-hole of an edge support of an adjacent formwork panel to form a complete hole.
  • a tension anchor may be inserted through a mutually spaced pair of formwork panels (manufacture of a concrete wall having a thickness equal to the distance between the formwork surfaces of the two formwork panels) and fixed to the form panels in the spacing of the formwork panels.
  • the tension anchor can be passed through holes in the middle region of the edge beam (especially well feasible if the edge beams have a hollow profile cross-section) or through holes in the area where the edge support and filling element abut each other are passed.
  • the two edge beams each have a length corresponding to an integer multiple, the same Greelementbreiten within the formwork panel.
  • the edge support and the filling elements can be combined particularly well with each other.
  • the edge member lengths are an integral multiple of the panel width (which in turn is either equal to the filler length or equal to the filler length plus twice a portion of the width of each edge support or equal to the filler length plus twice the edge support width). In this way, at a line formed by the transverse ends of a plurality of adjacent formwork panels, another formwork panel can be connected in a 90 ° rotated orientation.
  • all filling elements are formed substantially equal to each other.
  • the filling elements close to each other close to each other.

  • inter-engaging longitudinal projection on the edge support 4 or on side wall 100
  • engagement openings 136 are alternative means for cooperation with a connection lock 50. Depending on which means are more practicable, the designer can choose.
  • Engaging openings 136 can also according to the first embodiment Fig. 1 to 8 be provided.
  • Fig. 14b The possibility is shown graphically that instead of the connecting locks 50 of Fig. 14a Bolt 142 with an axially extending slot provides, in each of which a wedge 144 is inserted.
  • the wedge 144 is driven so far into the slot that either two edge support 4 or two side walls 100 or a rim support 4 and a side wall 100 between the bolt head and the wedge 144 are clamped together.
  • the respective pin 142 is defined by a pair of apertures 124 (or, more concretely, by the hollow pin 124 incorporated therein Pair of openings 124 inserted) inserted.
  • the bolt 142 is inserted through a pair of openings 146 in two adjacent edge beams.
  • the bolt 142 passes partly through an opening 124 and partly through an opening 146.
  • connection locks 50 or bolts 142 with wedge 144 or bolts can be used alternatively and depending on current requirements.
  • the compounds can be solved again immediately after completion of the respective concreting task, or it is also possible to keep several formwork panels 2 connected to one another for an extended period of time, e.g. if you have a larger length of shuttering that was not available at the site, composed of two or more shorter formwork panels 2 and this larger formwork length is later needed again at a different location on the site.
  • At least the smaller to medium formats of the formwork panel 2 according to the invention can be made available with such a low weight that a single man can pick them up and carry them to the installation site in the overall formwork. This usually applies to a limit of 40 kg. It has been found that, for example, a 60 cm wide and 270 cm long board 2 in the construction of the second embodiment according to Fig. 9 to 13 weighing less than 40 kg.
  • connection lock 50 or a bolt 142 or a bolt is to be attached on the inside (i.e. a metal strip.
