Definitions

  • the invention relates to a formwork panel for the erection of cast masonry, in particular for the erection of concrete walls with the features of the preamble of claim 1.
  • Such formwork panels are known. They are used in the construction of large structures and themselves have considerable dimensions, for example such formwork panels can be 3 m long and 1.5 m high. They are correspondingly heavy. They can only be handled with hoists.
  • Formwork panels of this type are joined together over a large area by juxtaposition and stacking and are connected to one another in a positive and positive manner by means of screws, bolts and / or wedges. It is difficult to exactly align and position these formwork panels when stacking them to form a formwork. Therefore, wedge-shaped intermediate pieces have already been provided and inserted in such a way that the formwork panel to be placed has been placed at a predetermined distance at right angles to the formwork surface so as to prevent the formation of heels in the formwork skin.
  • FR-A-2 663 356 should also be mentioned.
  • a chamfered pin is provided on the rail on the rear opposite the formlining, and a cylindrical hole is provided on the corresponding rail of the adjacent formwork panel.
  • the fastening screws provided here for bracing the formwork panels are located on the side and at a considerable distance from the journal and the cylinder bore receiving them. If the rails that support the pins and holes are not in direct contact with one another, there is a risk that the two panels will be tilted if the fastening screws are tightened differently.
  • the invention is based on this prior art and it aims to provide a constructive measure which avoids such a possible tilting of the formwork panels to be joined together, which is achieved according to the invention by those measures which contain the content and subject matter of the characterizing part of the Claim 1 are. Expedient embodiments of the invention are set out in the subclaims.
  • a formwork skin 3 which can be formed, for example, by a layered wooden plate.
  • a plurality of I-beams 14 arranged parallel to one another are fastened to the rear of this formwork skin 3, for example formwork beams which can be made of wood with an upper flange 15 and a lower flange 16 and an intermediate web 17.
  • These parts forming the I-beam 14 are shown in FIG glued together in a known manner.
  • Wall bars 18 made of U-shaped rails are used for stiffening.
  • the I-beams 14 are somewhat shorter than the height H of the formlining 3 and with respect to this formwork facing 3 so that their end faces on both sides are set back somewhat relative to the edges 19 and 20 of the formwork facing 3.
  • extension rails 21 and 22 are each formed from two box profiles 23 here.
  • These box profiles 23 of the upper extension rail 21 are connected between the webs 17 of the I-beam 14 by connecting webs 24, each of which carries a truncated cone-shaped pin 5, which is penetrated by a central bore 9.
  • the opening angle of these truncated cones is approximately 90 °.
  • the arrangement is made here (Fig. 5) that the truncated cone is between the box profiles 23.
  • the box profiles 23 of the lower extension rail 22 are also connected to one another in the manner mentioned by connecting webs 24, here these connecting webs 24 each having a hollow-conical abutment 10, these hollow-conical bushings 10 are designed to correspond to the pins 5.
  • the training discussed is provided at the top and bottom. It is within the scope of the invention to provide corresponding designs on all four edges of the formwork panels.
  • the pins and abutments which are designed as truncated cones and hollow cones, engage in one another in a positive manner and thus position the formwork panels to be combined with one another both in their longitudinal and in their transverse direction, so that the setting of such panels or the assembly of formwork from such panels is made considerably easier.
  • the fastening screws are then inserted through the bore 9 or 13 of the positioning elements.
  • conical positioning elements instead of conical positioning elements, it would be possible in principle to use elements with a cylindrical shape, but at least one of the two parts used for positioning should have a conical edge zone so that the parts used for positioning can easily move into one another when the formwork panels are set.
  • FIG. 7 two stacked formwork panels are shown, the formwork skin 3 of which is formed by a frame 1 made of box profiles.
  • the pin 5 is arranged on a leg 26 of an L-shaped profile rail 25 and this leg 26 carrying the pin 5 is connected to the frame rail of the formwork panel on the edge.
  • the outside of the other leg 27 of the L-shaped profile rail 25 lies flush with the shaping outside of the formlining 3.
  • the frame 1 of the formwork panels according to the embodiment of FIG. 7 are formed here from box profiles. It can also be seen from this figure that the height of the flush with the outside of the formlining 3 Leg 27 of the L-shaped profile rail 25 corresponds approximately to the height of the pin 5 or is somewhat higher than this.
  • truncated cones and hollow-conical abutments are shown and described as positioning elements, which are designed to correspond to one another, and it is within the scope of the invention to provide truncated pyramids and hollow pyramids as an abutment.
  • the abutment is formed circumferentially closed in the exemplary embodiments shown. It is possible to divide this abutment into individual sectors as seen in the circumferential direction and to leave gaps between these sectors, so that the pin entering the abutment does not abut an abutment surface over its entire circumference, but only along individual sections. If such an abutment is designed in this way, cleaning of the abutment is made easier if concrete should accumulate in it.
  • FIGS. 8 to 11 The pin 5 is formed here as a truncated pyramid, whereas the abutment 10 receiving this pin 5 is formed by four wedge blocks 28.
  • the formwork panel which is seen in Fig. 12 from the frame side, has a circumferentially closed, rectangular frame 1 made of U-shaped profile rails 2, these U-profile rails forming the frame being arranged such that their open sides face one another.
  • a formwork panel can have a length L of 3 m and a height H of 1.5 m.
  • the invention is not limited to formwork panels with these dimensions.
  • the formwork panel shown here in Figures 12 and 13 is a flat formwork panel.
  • the invention which will be explained in more detail below, can also be used in those formwork panels which have a curvature.
  • the actual formlining 3 is fastened, which can consist of metal, wood or plastic, or a combination of such materials.
  • the formwork skin 3 is expediently offset somewhat from the circumferential contour of the frame 1, as can be seen particularly clearly from FIG. 13.
  • pipe sections 4 welded with horizontal axes.
  • the pipe sections 4 serve to hold fastening screws with which formwork panels lying next to one another can be braced together. Openings can also be provided in the legs of the frame, which serve as push-through openings for fastening and connecting screws. However, this is not shown here.
  • pins 5 are fastened, for example welded, at equal distances from one another, which are shown in FIGS. 14 and 15 on an enlarged scale in cross section and are shown in plan view.
  • a pin 5 has a circular base plate 6, which merges upwards into a truncated cone 8 via a short cylindrical extension 7, the opening angle of this truncated cone being approximately 90 °.
  • This truncated cone 5 is penetrated centrally by a bore 9.
  • the base diameter of this pin 5 is considerably larger than its height.
  • abutments 10 which correspond to the truncated cones 8 are arranged in a corresponding manner, as described above.
  • These abutments 10 consist of a cylindrical base body 11 with a hollow cone 12, this hollow cone 12 merging into a bore 13. Bore 13, hollow cone 12 and the central axis of the cylindrical base body 11 coincide.
  • These truncated cones 8 and hollow cone 12 are each congruent with bores which are arranged on the cheeks of the profile rails 2 carrying them. This shows schematically the detailed representation according to FIG. 18. These bores serve as a push-through opening for fastening screws.
  • the components used to position the formwork panel are attached to the horizontal leg of the frame 1. It is within the scope of the invention to arrange these positioning parts also on the vertical legs of the frame 1.
  • formwork panels of the type described are relocated during operation, the truncated cones 8 and the hollow cones 12 engage in one another in a positive manner and position thus the formwork panels to be connected to each other both in their longitudinal as well as in their transverse direction, whereby the setting of such panels or the assembly of a formwork from such panels is made considerably easier.
  • the pins or the abutments are arranged on the outside of the rails.
  • the abutment it is also possible to provide it on the inside, but this is not shown here.
