Definitions

  • the invention relates to a receiving member for bearing or supporting the main beams positioned on the top of a temporary supporting structure adjustable in height.
  • supporting structures For casting concrete plates and floors on formworks in building constructions, one mostly employs supporting structures, which are mostly built into spatial structures.
  • the spatial structures are mostly formed by metal scaffolding parts, designed as posts, coupling pipes and diagonal pipes, and further main beams for direct support of the formwork with the usual connecting and adjusting possibilities.
  • the top surface of the supporting structure, to wit the main beams, should be adjustable in height to allow usage for any height.
  • the height adjustment is achieved with posts designed as an inner pipe, which is vertically adjustable within an outer pipe of the post by a screw spindle structure.
  • the main beams extend across several points of support, to wit the posts.
  • main beams are to be mounted at a given height and after setting of the concrete surface, these must be removed from underneath the surface or the formwork by hand, said main beams are mostly embodied in (extruded) aluminium.
  • Main beams extending across several points of support affect the loads arising on the posts as a result of the occurrence of bending moments in said beams above said points of support. This provides an unequal bearing force distribution in the posts and due to that, the points of support or posts across which the main beams extend, will have to be dimensioned for said heavier loads.
  • a further disadvantage of the continuous main beams, which are generally not reinforced at their extremities, is that the extremities can easily get damaged, which may lead to an unfavourable direction of forces into the supporting structure.
  • the object of the present invention is to provide a modified and improved temporary supporting structure that does not have the above-mentioned disadvantages and can be put onto the market in an economically sound way.
  • a stabilizing receiving member is incorporated in the temporary supporting structure in an inventive way, characterized in that said receiving structure is provided with means for bearing and centring adapted head ends of main beams with provisions having been made for interconnecting and stabilizing the top plane of said supporting structure.
  • the advantage is that the top plane of the temporary supporting structure forms a very stable surface underneath the formwork.
  • the receiving member according to the invention is developed further in such a way, that said adapted head ends of the main beams are bevelled and can be retained between V-shaped upstanding wings of said supporting structure.
  • the advantage is that the head ends will bear on the receiving member in a stable way.
  • the receiving member according to the invention is developed further in such a way, that said retaining facility has been established by a retaining cam with a corresponding recess in the bottom side of the bevelled head ends of main beams, so that a centric connection can be achieved.
  • the receiving member according to the invention is developed further in such a way, that said facilities for mounting said interconnecting means are brackets welded to the V-shaped raised wings, a connecting lip being provided at the extremities of the interconnecting rods gripping over them.
  • the advantage is that a properly stabilizing structure of the top surface of the temporary supporting structure has been obtained.
  • Figure 1A shows a vertical longitudinal section of the top side of a temporary supporting structure 1 as employed at the moment (state of the art), in which figure 1B shows a vertical cross-section thereof.
  • the upper vertical posts 4 are embodied as outer pipes 3 provided with screw spindle 5 with inner pipe 6 for height adjustment of the main beams 7 having the usual formwork carriers 8 with the formwork parts 9 thereon.
  • the main beams 7 continue across at least one post 4, thus causing the post 4 across which main beam 7 extends to withstand a higher vertical bearing force.
  • the vertical posts 4 should be interconnected and strutted for reasons of stability. In the known construction according to the figures 1A and 1B this takes place with the interconnecting bars 10 and 11 and the diagonal bars 12 and 13.
  • interconnecting by means of interconnecting bars 10 and 11 and strutting by means of diagonal bars 12 does not occur at the level of the main beams 7, due to which stabilizing the supporting structure 1 in relation to horizontal forces is less effective and may lead to unstable situations.
  • Figures 2A and 2B illustrate the same vertical cross-sections of a supporting structure 1 provided with the receiving member 14 according to a preferred embodiment of the invention. See also figures 3 , 4 and 5 .
  • the receiving member 14 is inserted in the inner pipe 6 of the vertical post 4 by a short piece of pipe 15 (see figures 4 and 5 ).
  • FIG. 5 shows receiving member 14 according to a preferred embodiment of the invention in a perspective view.
  • a head plate 16 is welded to said short pipe 15 and an I-shaped profile 17 having V-shaped wings 18 and a body 19 is welded to said head plate.
  • Brackets 20 are welded to said V-shaped wings 18 for (torsionally stiff) connecting lip 21 of the interconnecting bars 22 to them.
  • a diagonal bar 30 can be connected in the way indicated.
  • a facility is mounted for tension stiff support of bevelled adapted head ends 23 of the adapted main beams 23, said facility gripping behind retaining cam 26.
  • a bolt (not illustrated) can secure head plate 16 to the head plate 27 of the inner pipe 6 of the post 4, to which end the slots 28 and 29 have been provided.
  • Figures 3 and 4 illustrate receiving member 14 in a mounted state ( figure 3 ) and in exploded view ( figure 4 ).
  • the bevelled head ends 23 are provided with reinforcing strips 31.
  • the adapted main beams 24 extend from receiving member 14 to receiving member 14 and are therefore girders on points of support at both extremities (statically determined).
