Definitions

  • the invention relates to slab formwork with the features of the preamble of claim 1.
  • DE-A 1 434 365 teaches, according to the preamble of claim 1, to design the projections as pegs which are used for connection to adjacent formwork panels. Flanges are also provided as reinforcements on the edges of the formwork panels. This results in a relatively good stabilization of the formwork panels in the slab formwork, but only if the formwork panels are inserted accurately.
  • the invention is based on the object of providing a slab formwork in which both slipping of the formwork panels attached to the head piece, pivoted downward from the head piece and lifting of the formwork panels resting on such head pieces in a direction offset by 90 ° from the head piece in the case of incomplete form Support, d. H. when supported, for example, only at two corners, is effectively prevented.
  • the pegs are arranged according to the invention on approaches located at the corners of the base plate.
  • the formwork panels can be attached to the pin-like projections and pivoted about them without the projections having to be movable relative to the base plate and without the risk that the attached formwork panels can slide off the pins, even if the formwork panels only have one edge are held by two pins and hang down vertically from the base plate.
  • the base plate with the pins attached to its corners consists of one piece and is therefore inexpensive to manufacture and also extremely robust for rough construction site operation.
  • the lugs are provided in pairs at a mutual distance on the long sides of the base plate, while on the top of the base plate between the lugs in the longitudinal direction of the base plate there are cross-sections which are T-shaped in cross-section, the upper straps of which project from an outwardly projecting flange or a recess in the Crossbars are to be gripped under or gripped around a formwork panel.
  • each of the longitudinal sides of the rectangular base plate in the plan into which a longitudinal spar of the frame of a panel to be attached can engage when the panel hangs down.
  • the cross-sectionally T-shaped webs on the top of the base plate serve as stops for positioning the formwork panels on the relevant head piece.
  • a bar-shaped spacer for the adjacent formwork panels running at right angles to the two webs can be arranged on the base plate in the center, so that the four formwork panels to be supported by a head piece can be brought into the correct formwork position with the aid of the webs and the spacer, without that a person would have to climb the formwork for this.
  • the pins arranged on the lugs of the base plate are preferably frustoconical. This makes it easier to attach the formwork panels, which, however, cannot slide off from such pins because of the inwardly projecting flange attached to their crossbars, even if they hang practically vertically and perform an oscillating movement.
  • the formwork panels can be attached to the head pieces easily and quickly, or can be detached from them and swung up into the operating position, for which it is sufficient to attach a next steel tube support with a corresponding head piece to the opposite end of the formwork panel and the Then swivel the control panel up when the steel tube support is erected.
  • a plug that fits into a steel tube support is arranged centrally, so that the head pieces are simply attached to the upper end of a steel pipe support can put on. No further attachment is necessary.
  • the slab formwork usually consists of a number of formwork panels 1, the four corners of which are each supported on a head piece 2, which is explained in more detail below.
  • Each formwork panel has a plate 3 serving as formwork skin and a frame supporting it, which consists of profiled cross members 4 and also profiled side members 5.
  • each transverse web 4 contains a slot-like opening 7 near its lower edge, the purpose of which is also explained below.
  • FIGS. 4 and 5 Details of the head pieces 2 used for supporting the corners of the formwork panels 1 can be found in FIGS. 4 and 5.
  • the head piece has an elongated base plate 8 which is rectangular in plan view, on the longitudinal edges or longer side edges of which two projections 9 which are essentially rectangular in plan are subsequently formed on the front ends. Between the projections 9 formed in pairs on the two long sides of the base plate 8 there is a free space 10, the width of which, as shown in FIG. 4, is greater than the width of each of the projections 9. In this free space 10, the side members 5 or side rails of the frame of the individual formwork panels 1 can dodge when these formwork panels are swiveled into the position shown in FIG. 2 or attached to the head pieces in this position.
  • each lug 9 there is an upstanding truncated cone-shaped pin 11.
  • the pins 11 of the head pieces 2 are gripped by the flanges 6 of the cross bars 4 of the individual formwork panels 1 when the corners of the formwork panels are at the head pieces 2 hangs and is supported on this. From Fig. 2 it can be seen that the inclination of the flanges 6 corresponds approximately to the inclination of the truncated cone-shaped pin 11, so that the attached Wennafein can not slip off the head pieces 2 even if they can be seen in the vertical position in Fig. 2 on the Hang head pieces.
  • the base plate 8 At the two ends of the base plate 8 are arranged on the top thereof two cross-sectionally T-shaped webs 12 and 13, the upper straps 14 of which engage in the openings 7 of the cross bars 4 of the formwork panels 1 when they are in the horizontal position, as in FIG 1 and 2 can be seen.
  • the slot-shaped recesses or openings 7 are therefore expediently only in the corner region of the cross bars 4.
  • the engagement of the upper straps 14 in the openings 7 prevents the formwork panels 1 from being lifted off the head pieces, even if the formwork panels are not properly on four head pieces 2 rest, as is indicated, for example, in FIG. 3 in dash-dotted lines.
  • a transverse web-shaped stop 15 is arranged on the upper side thereof, which serves as a contact for the corners of the adjoining, adjacent formwork panels.
  • the width of this stop 15 corresponds approximately to the distance between the longitudinal beams or longitudinal spars of adjacent formwork panels 1, so that they meet with their formwork panels 3.
  • the stop 15 is provided to fix the lateral position of adjacent formwork panels 1.
  • the head piece shown in FIGS. 4 and 5 is designed as a one-piece cast body. Therefore, it is an easy to handle and robust item.
  • a plug-in 19 is inserted from below into the neck 16, with the help of which the head piece 2 can be inserted and pegged into the hollow steel tube support 18 from above.
  • the connector-like connector 19, which looks like a plug and is welded to the projection 16, can be seen.
  • the inwardly projecting flanges 6 of the formwork panels 1 can also be replaced and / or supplemented by other devices having the same effect.
  • a gusset plate in the corners of the frame of the formwork panels 1.
  • Such knot plates arranged on the open side of the frame che correspond in their effect to the inwardly projecting flanges 6.
