Definitions

  • the invention relates to a girder for slab formwork, which connects each column of the slab formwork and carries formwork panels which can be fastened in alignment between them and neighboring girders, the girder having at both ends a fastening device for releasable connection to the supports and preferably a formlining on its upper side has and its length and thus the distance between its attachment points, preferably continuously, is adjustable.
  • the pull-out part has an outer cross section which corresponds approximately to the inner cross section of the carrier. This results in relatively little stiffness Support parts, which also prevent stiffening, especially in the area of the support in which the displaceable part enters the rest of the support part.
  • Such a relatively soft construction is disadvantageous, especially when bridging larger distances, when the girder has to be increased in length, its load-bearing capacity is also reduced.
  • the carrier mentioned at the outset is characterized in that one of its fastening points on an end piece or the like is arranged on the end face of at least two guide tubes which are adjacent to one another in a plane parallel to the formlining and which with this end piece are opposite a guide in the carrier are guided displaceably in their longitudinal direction, and that at the end opposite the end of the guide tubes in their extensibility limit stop is provided, which cooperates with a counter-stop of the carrier, which maintains a minimum distance from the outlet opening of the guide tubes from the carrier.
  • Two parallel guide tubes lying next to each other have the advantage of providing good stiffening, especially in the horizontal direction, but at the same time allowing stiffening between themselves on the support if necessary. Furthermore, on top of two such a piece of formwork skin is placed on parallel pipes, which is thus already correctly oriented. Through the stop with a minimum distance from the outlet opening, a minimum insertion depth remains, which, with appropriate design of the guide elements together with at least two tubes, results in considerable bending rigidity in all directions, especially since two pipes are also more rigid than a guide body corresponding to the inner cross section of the carrier, since more in vertical web areas are present on these tubes.
  • the parallel guide tubes are designed as square tubes, the flat sides of which run parallel or at right angles to the formlining. In these directions, they can therefore absorb high loads and bending forces, while the upper flat sides at the same time form a good support for a formlining to be inserted when the guide tubes are pulled out.
  • the flat sides of the square tubes which are at right angles to the formlining, form a total of four webs which act to stiffen against deflection of the extended beam.
  • Embodiments of the invention are the subject of further claims. It is particularly expedient if the end piece for engaging at attachment points of a support head of a support, for example according to DE-PS 30 03 682 from below, is a cross-sectionally L-shaped angle rail or the like at the outer ends of the guide tubes.
  • one leg covers the end faces of the tubes, connects and fixes against each other and the other leg as Be Fixing flange is provided with fastening points, in particular perforations or the like.
  • a beam designated as a whole serves to ver supports of slab formwork, not shown tie, so that then with these aligned formwork panels can be attached between such carriers.
  • These formwork panels can be connected, for example, by means of edge webs on their end faces to the longitudinal surfaces 2 of the carrier 1.
  • the carrier 1 itself has a formwork skin 3, which is in alignment with the formwork skin of the formwork panel in the use position.
  • the length of the carrier 1 and thus the distance between its attachment points 4, with which it can engage the supports are adjustable.
  • one of the fastening points 4 is provided on an end piece 5, which is arranged on the end face of two guide tubes 6 lying next to one another in a plane parallel to the formlining 3.
  • These guide tubes 6, together with this end piece 5, are displaceable in their longitudinal direction relative to a guide to be described in the carrier 1 and at the end of the guide tubes 6 opposite the end piece 5, which remains inside the carrier 1, there is provided a stop 7 limiting its extensibility, which interacts with a counter-stop 8 of the carrier 1, which maintains a minimum distance from the outlet opening 9 from the carrier 1.
  • the parallel guide tubes 6 are designed as square tubes, the flat sides 6 a of which are parallel and the flat sides 6 b of which run at right angles to the formlining 3.
  • the flat sides 6 a thus form a good contact surface for one in the extended Be richly to be placed on the guide tubes 6 formwork plate 10.
  • the flat sides or webs 6b bring about good stiffening, especially since they have a larger cross-sectional length than the other flat sides 6a of the guide tubes 6 according to FIG. 3.
  • a plate which engages over the inner end faces of the tubes 6 opposite the end piece 5, is connected to it and bridges the gap, in particular welded plate.
  • a counter-stop 8 on the carrier 1 is an inner piece fastened between the guide tubes 6, which at the same time connects and braces horizontal guide plates 11 and 12 to be described.
  • the aforementioned plates 11 and 12 are also provided in the carrier 1, the spacing of which corresponds to the outer thickness of the guide tubes 6, which can be seen particularly well in FIG. 2. It is again advantageous that the guide tubes have a rectangular cross-section, because in this way the plates 11 and 12 on the flat sides 6 a can attack, but with enough play to move them.
  • the guide plates 11 and 12 are arranged in the carrier 1 parallel to the formlining 3.
  • the upper guide plate 11 in the use position has at the end of the carrier 1 a raised edge 13 as a stop for the formwork skin 3 and the further, in the extended space insertable formwork plate 10.
  • the edge 13 is as high as the end piece 5, so that both parts are flush when pushed together, in which they lie against each other .
  • the side walls 2 of the carrier 1 have an elongated slot 14 in the exemplary embodiment for attacking fastening elements for connecting formwork panels, which also facilitates adaptation to different lengths of the carrier 1 and any different fastening points that may result therefrom.
  • the end piece 5 for engaging attachment points of a support head of a support is a L-shaped cross-section rail, one leg 5 a of which covers the end faces of the guide tubes 6, connects and fixes against one another, and the other leg 5 b as an attachment flange with attachment points 4, in particular perforations or the like.
  • a bracing 15 encompassing the angle rail between the two guide tubes 6.
  • the guide tubes which are rectangular in cross section and thus very stiff in all directions, are advantageously guided on a total of three sides, the guide located between them at the same time forming the counter stop 8 for limiting their extensibility and additionally braces the beam in this area.
  • the overall result is a beam for slab formwork, which has good rigidity even with the greatest length, without complex inner frames and the like.
  • stiffeners to need because the selected construction elements for the guide and for the stop simultaneously contribute to stiffening and reinforcing the beam in the guide area.
