Definitions

  • the invention relates to an arrangement in formwork or armor, which has a rod section with a head plate attached to its end, the edge of which protrudes on at least one side beyond the cross-section of the rod, in particular to a column head, the arrangement providing a connection possibility that can be fastened to the rod end for adjacent elements containing connector that has at least two suitable for clamping the rod section between them jaws.
  • a device for supporting beams for slab formwork which is clamped to the bar section by means of a wedge which is driven in transversely to a bar section and which cooperates with a V-shaped clamping jaw.
  • the wedge presses radially from the outside against a point on the circumference of the rod section.
  • the bending stiffness of this device is often not sufficient, it just sits on the head plate. If the device is attached to a lying bar, an undesirable space can even arise between the head plate and the device.
  • the invention therefore also relates to rod sections not used as supports, at the end of which a plate extending at right angles to the rod axis is fastened.
  • the invention has for its object to produce a rigid connection between the end of a rod section having a head plate and an adjacent element of the formwork or armor, which is suitable for connecting different other parts of the formwork or armor.
  • clamping jaws by a clamping device acting obliquely to the rod axis are connected to one another, the clamping jaws having stops which enclose the cross section of the head plate between them during tensioning.
  • connection part Since a special connection part is switched on between the rod end and the element of the formwork or armor to be fastened to the rod end, this connection part can have fastening options for several different formwork or armor elements to be fastened to the rod end, for example bores in different hole patterns, support strips or support surfaces or the like .
  • Commercial supports therefore do not have to be modified themselves to adapt them to support a specific element to be supported. Such an adjustment of the support itself would limit its multiple uses.
  • the clamping device acting obliquely to the clamping axis has the particular advantage that the clamping jaws are not only pressed radially onto the cross-section of the rod, but also components of the clamping force which run parallel to the rod axis and which endeavor to displace the clamping jaws in opposite directions to one another.
  • the jaw on which the clamping device engages at a greater distance from the head plate than in the other jaw is moved towards the head plate, the other jaw towards the head plate.
  • the clamping jaws have stops that enclose the cross-section of the head plate between them during clamping, i.e.
  • connection part can be dimensioned sufficiently strong without difficulty, such a connection between the connection part and the support can be more rigid than the known welded connection between the rod end and the head plate.
  • connection options of the connection part can be designed such that the connection between the connection part and the element to be connected to the rod end is as firm as is necessary, for example also has the required flexural rigidity.
  • the connection between the rod end and the element to be fastened with the interposition of the connecting part can be more rigid than in the event that the element to be fastened is fastened directly to the rod end.
  • the stops which enclose the cross-section of the plate between them, that is to say attack the top and bottom of the plate edge which protrudes beyond the rod cross-section, can be designed differently.
  • the stops attached to the two clamping jaws can be designed in the manner of a screw clamp, these stops then lying in a plane in which these stops move towards one another when tensioned.
  • the stops can also lie in different planes running parallel to the rod axis, for example on opposite sides of the rod section and therefore be arranged in the immediate vicinity of the jaw in question.
  • the stop of the jaw to be moved on the head plate during clamping is formed directly by the end, for example the end face of the jaw.
  • the clamping device has enough play to be able to press the clamping jaws onto rod sections with different diameters.
  • the clamping jaws themselves have a V-shaped cross section, so that bar sections with a round or angular cross section can be easily encompassed by the clamping jaws.
  • the clamping device is pivotably mounted on at least one clamping jaw.
  • This has the advantage that regardless of the diameter of the rod, the two clamping jaws can be placed before the start of the clamping in such a way that the stops of the clamping jaws are already in contact with the head plate, i.e. the stop of the clamping jaw moving away from the head plate on the ( upper) surface of the head plate, which faces away from the rod section, whereas the stop of the clamping jaw moving towards the head plate during clamping rests on the opposite plate surface.
  • the pivotability of the clamping device also ensures that the connecting part is pressed without play both on the circumference of the rod section and on the two surfaces of the head plate. This also prevents this from possibly shifting in the direction of the rod axis when the connecting part is loaded.
  • the connector is to be used only for a specific rod cross-section, it is not absolutely necessary to pivotally attach the clamping device to the clamping jaws, it may then be sufficient to fix the clamping device in such a way that the inclined position of the clamping force relative to the rod axis does not change. It is useful, however, if there is at least as much play in the clamping device that the clamping forces acting on the head plate and the forces acting on the circumference of the rod section are statically determined even with the rod cross-section always the same.
  • the tensioning device itself can be designed in various ways in embodiments of the invention.
  • the tensioning device contains at least one tension rod which is mounted on the clamping jaws with so much play that it can adjust its inclined position to the rod diameter.
  • the connecting part is anyway attached to the rod section in such a way that the stop of the jaw moving away from the head plate during tensioning and the stop of the jaw moving towards the head plate during tensioning are not too far away from the surfaces of the head plate, so that when clamping the clamping plates and the stops come into contact approximately simultaneously with the circumference of the rod or with the head plate.
  • a head plate 2 is welded onto the upper end of a cylindrical, tubular support 1.
  • a support plate 6 has a V-shaped cutout in which the back of the bracket 4 forming the jaw is fastened, for example welded.
  • the plane of the support plate 6 extends obliquely to the support axis 7.
  • a cross bar 8 is fastened, for example welded, to the edge of the support plate 6 facing away from the support, the ends of which protrude beyond the lateral edges of the support plate 6.
  • elongated holes 9 are provided in the cross bar, through which the legs 10 of a U-shaped clamping device are passed.
  • Wing nuts 11 are screwed onto the ends of the legs 10, their surfaces abutting the cross bar 8 are curved so that the inclined position of the legs 10 can vary.
  • the jaw facing the jaw 3 has a rod 12 consisting of a rectangular hollow profile, on the side facing the support 1 near its upper end a plate 13 and near its lower end a plate 14 is fastened, for example welded, which are each supported by oblique struts 15 on the rod 12.
  • the ends of the plates 13 and 14 facing the support 1 have a V-shaped incision 16. The length of the plates 13 and 14 and thus the distance of the rod 12 from the axis of the support 1 is so great that the rod 12 can protrude above the head plate 2 beyond the edge of the head plate 2 of the support 1.
  • a plate 17 is fastened, which in the exemplary embodiment shown covers the entire head plate 2 and carries at its end facing away from the rod 12 a sleeve 18 for fastening an adjacent formwork or scaffolding element.
  • an angle 19 is fastened, for example welded, which protrudes laterally beyond the rod 12 on both sides and has elongated holes 20 at its ends, through which the legs 10 likewise pass, which pass through an on the inner surface of a leg of the angle 19 extending yoke 21 are interconnected.
  • a laterally projecting plate 22 which, like the horizontal leg of the angle piece 19, has fastening options for adjacent formwork or scaffolding elements.
  • the distance of the angle 19 from the plate 17 is smaller than the distance of the plate 6 from the plate 17, so that each leg 10 and thus the direction of the clamping force extends obliquely to the support axis 7.
  • the lean the leg 10 is variable because of the pivotable mounting of these legs in the elongated holes 20 and 9. It automatically adjusts to the diameter of the support 1.
  • the connecting part is placed over the end of the support so that the plate 17 rests approximately on the head plate 2 and the upper end face of the jaw 3 is not too far from the lower surface of the head plate 2 projecting beyond the circumference of the support 1. If the clamping device is then tightened by screwing on the wing nuts 11, not only the clamping jaws 3 and 13, 14 are pressed against the circumference of the support 1 by the oblique course of the clamping force in the legs 10, but also a pair of forces arises parallel to the support axis 7 1, which pulls the clamping jaw 3 in FIG. 1 upwards against the lower surface of the head plate 2, the clamping jaws 13 and 14 and thus the plate 17 and thus presses the plate 17 onto the upper surface of the head plate 2.
  • the cross section of the plate 2 is therefore pressed in when the clamping device 10, 11 is tightened between the upper end of the clamping jaw 3 and the plate 17, so that the connecting part is not only seated radially to the support axis 7, but also parallel to it and is rigidly rigid with the support 1 is connected.
  • adjacent elements of the formwork or the scaffold can then be fastened again in a manner that is resistant to bending and adapted in these elements.
  • the rod 12 is longer than the jaw 3, so that the plate 14, which represents the lower jaw, comes to rest below the lower end of the jaw 3 on the circumference of the support 1.
  • the surface of the wing nuts 11, which comes into contact with the crossbar 8 when tensioned, is curved so that the clamping force exerted by the wing nuts 11 can be transmitted unhindered to the cross bar 8.
