Definitions

  • the invention relates to a formwork panel with peripheral profiles running around its edges and between these stiffening girders arranged to stiffen the formlining, and with tensioning points penetrating the formwork panel for inserting formwork tie rods, which tensioning points are arranged at a distance from the edge profiles, with a cross connection at each tensioning point in the assembly position is provided on two spaced stiffening beams.
  • Such a panel is known from US-A-4,744,541.
  • perforations penetrating the formlining between two parallel stiffening girders are known for inserting formwork tie rods.
  • wedge elements which can be moved transversely to these are provided, which overlap the two parallel stiffening girders on their rear sides facing away from the formlining and thus bring about the introduction of the forces from the formwork tie rods onto the stiffening girders. This means that the wedge element must be removed to release the formwork tie to release the formwork panel to release the formwork tie rods.
  • the perforation in the formlining weakened the formwork panel.
  • the formwork panel mentioned at the outset is characterized in that the cross-connection is arranged as a cross member fastened between the two stiffening members.
  • the tensioning point preferably a plurality of tensioning points, located on this cross connection, which is designed as a cross member Distance to the outer edge profiles, i.e. without their impairment, without instead weakening or impairing the stiffening girders and without having to attach a bridging element to two parallel stiffening girders both when shuttering and when stripping.
  • the tension points are even reinforced by the cross connection.
  • this formwork panel horizontally in the area near the ground without preventing or complicating the installation of the formwork tie rods there.
  • joint tapes and the like can be provided in the region of the joints between adjacent formwork panels without hindering tensioning there. Nevertheless, the forces emanating from the formwork tie rods are easily introduced into the formwork panel, and the tensioning forces emanating from the formwork tie rods can advantageously be distributed over two preferably parallel stiffening girders without having to provide a clamping point directly on a stiffening girder.
  • stiffening girders have a corresponding outer cross-sectional shape and if at least one of the two stiffening girders connected to the cross connection is reinforced compared to the other stiffening girders and / or has a larger material cross section.
  • This enables the forces emanating from the formwork tie rods to be introduced without any problems.
  • the overall appearance of the formwork panel is uniform with respect to the stiffening brackets, so that possibly attacking supports, belts and the like can be attached to all of these stiffening brackets with corresponding fastening means or transition pieces on these stiffening brackets.
  • stiffening girders running between the edge profiles are expediently arranged parallel to one another and to one of the edges of the formwork panel and, in the position of use, run particularly horizontally - accordingly vertically with the arrangement lying flat - and the cross connections with the tensioning points are expediently arranged approximately at right angles between two parallel stiffening girders.
  • these cross connections are as short as possible and guide the clamping forces to the two parallel bracing members in a correspondingly short way.
  • the stiffening beams can be approximately U-shaped or trapezoidal Have cross-section, the opening of this cross-section being closed by the formlining, which overall leads to good stiffening of the formwork panel in a known manner, and perforations for attaching accessories can be provided on the crossbars of the stiffening girders facing away from the formwork panel. Since the outer contour of all stiffening brackets essentially coincides, that is to say that the reinforced stiffening brackets do not have a different outer contour, these accessories and in particular their connecting connections to these stiffening brackets need not be designed differently.
  • a particularly simple implementation of the invention can provide that the U-shaped or trapezoidal stiffening girders in the region of the tensioning point are formed from thicker sheet metal than the other stiffening girders for their reinforcement.
  • stiffening webs, sheets or the like are inserted, in particular welded, into their hollow cross section. If this measure alone is sufficient to reinforce the stiffening girder, it can itself advantageously be made from the same sheet or the same rolled profile as the other, unreinforced stiffening girders of the formwork panel.
  • An increase in the outer dimensions of the formwork panel can be made possible by the fact that beams run approximately in the middle parallel to the preferably vertical edge profiles, which the stiffening beams meet from both sides and in particular are butt-welded.
  • the externally arranged edge frame is not sufficient, but to a certain extent two such frames are provided, between which the stiffening girders then run, it is advantageous that the tensioning points are not provided in the profiles running around the edge, but offset inwards, because otherwise the distance between two clamping points would be too large or there would be too many clamping points, namely if a third clamping point would also be provided between two clamping points located on the edge profiles and on the profiles located in the middle of this enlarged panel.
  • the repositioning of the tensioning points away from the edges of the formwork panel also permits the arrangement of only two tensioning points lying next to one another at the same height, even with such an enlarged formwork panel, the forces emanating from the formwork tie rods then being introduced into the reinforced stiffening beams.
  • connection elements and additionally have transverse perforations for connection bolts, crane or transport attachments or the like. These transverse perforations, by means of which, for example, two formwork panels arranged next to one another in a plane can be connected, can be provided at any point, since the presence of tensioning points does not have to be taken into account.
  • a further or additional measure for reinforcing stiffening girders which can advantageously also be carried out for the stiffening girders that are not directly in the area of the tensioning point, but above all also helps to be able to absorb the tensioning forces on the stiffening girders close to the tensioning point, may consist in that the transverse web provided on the U-shaped or trapezoidal stiffening girders facing away from the formlining has a bead or the like. Deformation, in particular a trough-shaped cross-sectional shape, this trough being concave, in particular when viewed from the outside.
  • a formwork panel with high rigidity results, in which the clamping points can be placed so cheaply that rectangular formwork panels can also be used lying down without the formwork tie rods being too close to the ground or in the area of joint sheets or the like.
  • the clamping forces can still be absorbed well.
  • the stiffening brackets have a matching outer shape, so that any stiffening brackets, including the reinforced, additional parts can be easily connected with matching fastening elements.
  • a formwork panel 1 has on its edges circumferential, cross-sectionally hollow edge profiles 2 (cf. especially FIG. 2) and stiffening supports 4 and 5 arranged between them for stiffening the formlining 3. Furthermore, on the formwork panel 1 these are penetrating clamping points 6 for pushing through Formwork tie rods are provided, which are designed as perforations and sleeves 7.
  • Fig. 1 it can be seen that the clamping points 6 are arranged at a distance from the edge profiles 2 on or at a stiffening beam 4,
  • Fig. 2 illustrates that the stiffening beams 4 and 5 have a corresponding outer cross-sectional shape, but that the or the stiffening beams 4 are reinforced in the area of the respective clamping point 6 and / or have a larger material cross section.
  • a cross-connection 8 is welded between two spaced and parallel stiffening beams 4, which the clamping place 6, and that at least one of the two with the cross-connection 8 stiffening beam 4 is reinforced compared to the other stiffening beams 5.
  • the tensioning force is thus transmitted to the reinforced stiffening girder 4 via this cross connection 8.
  • the cross-connection 8 is a hollow profile, expediently even a hollow profile that is closed on all sides, and the tensioning point 6 is formed by the sleeve 7, which already passes through this hollow profile.
  • the outside 8a of the cross connection 8 is expediently arranged at the same height as the outer webs 4a of the stiffening webs 4, so that the tensioning forces exerted, for example, by a tension nut on the cross connection 8 are introduced into the stiffening beam 4 over the entire height.
  • the stiffening brackets 4 and 5 running between the edge profiles 2 are arranged parallel to one another and to one of the edges of the formwork panel 1 and, as shown in FIG. 1, generally run horizontally in the position of use.
  • the cross connections 8 with the clamping points 6 are arranged approximately at right angles between two parallel stiffening beams 4.
  • the stiffening beams 4 and 5 have an approximately U-shaped or - as can be seen in FIG. 2 - trapezoidal cross section, the opening of this cross section being closed by the formlining 3.
  • the U-shaped or trapezoidal stiffening beams 4 in the area of the clamping point 6 can be formed from thicker sheet metal than the other stiffening beams 5 to reinforce them.
  • Fig. 2 shows that, however, additionally or instead of reinforcing the or the bracing brackets 4 near the clamping point, bracing webs 10 or bracing plates or the like can be inserted, in particular welded, in their hollow cross section. This would also allow reinforcement of the stiffening beams 4, which are made from the same sheet thickness as the stiffening beams 5.
  • a further reinforcement of the stiffening girder 4 results from the fact that the transverse web 4 a facing away from the formlining 3 has a bead or the like. In the exemplary embodiment it has an approximately groove-shaped cross-sectional shape, this groove being concave when seen from the outside. So that all stiffening beams 4 and 5 have the desired matching outer cross-sectional shape, the stiffening beams 5 also have this bead on the crossbar 5a.
  • a formwork panel 1 is shown of particularly large dimensions, in which the invention and in particular the arrangement of the clamping points at a distance from the edges is particularly advantageous. It is in fact sufficient, in spite of the practically doubled width of the formwork panel 1, if only two such tensioning points are present at the two altitudes in which tensioning points 6 are provided. Both the spacing of these tensioning points from one another and from the tensioning points of adjacent formwork panels is nevertheless not too great, which should be feared if the tensioning points were provided directly on the edge profiles 2.
  • this enlarged formwork panel 1 run approximately in the middle parallel to the vertical edge profiles 2 beams 11, which meet the stiffening beams 4 and 5 from both sides and in particular are butt welded.
  • the edge profiles 2 are provided for the engagement of clamps or the like. Connection elements and are provided with a channel-shaped indentation 12 for the engagement of the clips. In addition, they have cross holes reinforced by sleeves 13 for connecting bolts, crane or transport attachments, which can easily be tolerated at these edge webs 2 because they are not weakened by tension points penetrating them.
  • Fig. 2 shows that the clamping point 6 is arranged outside the center of the cross-connection 8 and indeed closer to the center of the formwork panel 1, that is also closer to a stiffening beam 4 further away from the edge profile 2.
  • the desired distance of the tensioning point from the corresponding edge of the formwork panel is increased somewhat, so that joint plates or the like can be provided without problems, without hindering the attachment of the formwork tie rod and without the formwork tie rod having the dimensions of such a joint plate or the like. limited.
