Definitions

  • the invention relates to a support system for the form plates or panels of a concrete flooring which has to be cast, said support system comprising posts for supporting primary beams, which as such may serve for supporting form plates or panels with which use can be made of depoty beams.
  • the object of the invention is to execute such a system in such a way that it is possible to remove given parts of the support system after the concrete is partly hardened by which a short building cycle can be realized. In this case, however, at least a number of posts will have to be maintained till the concrete is completely hardened.
  • the posts are provided with height-adjusting means near at least one of their ends in such a way that the upper surface of the posts is coming to lie in one plane with either the lower surface of the flooring to be cast or with the lower surface of a form plate, the upper end of a post being shaped by a vertical drop head over which a drop plate is movable in vertical direction, said drop plate being positioned in a mainly horizontal plane and serving to support the primary beams, said drop head comprising means for holding the drop plate at a given place, said means being executed such, that after casting the concrete and after this is at least partly hardened, the drop plate can be moved downward over a given distance for removing given parts of the support system.
  • the primary beams as well as the form plates or the form panels and the propely beams, if any, can be removed after the concrete is partly hardened, so that all these parts can be directly used again by which the efficiency of such a support construction can be considerably increased.
  • the means for holding the drop plate at a given place in respect of the drop head is shaped by a nut having a helically shaped lower surface resting on a round pin radially extending through the drop head, said nut being provided with an inner radial recess such that the nut can be moved along said pin upwardly in axial direction and after this can be rotated to bring the lower surface onto the pin, after which by further rotating the nut and by this the drop plate will move gradually upwardly till it is engaging an abutment.
  • the drop plate By rotating back the nut so the drop plate can be gradually moved downwardly so that it is then possible to remove the primary beams, the form panels and the form plates, if any. After this the nut can be further rotated so that the recess of it can be moved along the pin in the drop head and the nut can move further downwardly. In case of the device according to the invention so the primary beams and further parts, if any, can easily be removed.
  • the drop plate will be provided with four lips which are positioned over 90° in respect of each other and are extending obliquely upwardly, the end of a beam being provided with a recess to receive a lip such that a beam is locked in respect of the drop plate and a clamping action will arise between the beam and the drop head.
  • the primary beams will be provided with an obliquely upwardly extending rim along at least one of their longitudinal edges to receive the ends of depoty beams.
  • These depoty beams may form part of a form panel or not, the upper surface of the form panel then being shaped by a form plate.
  • connection bolts need to be applied between the beams by which the mounting and demounting of the support system is considerably facilitated.
  • a primary beam may consist of an aluminium profile obtained by extrusion and being provided with end parts to be put onto and coupled with the drop plates.
  • the depoty beams are composed of a mainly U-shaped profile and two end parts connected to this profile and being mainly K-shaped, such that the intermediary beams can be put down into two different height positions onto the upwardly extending rims of the longitudinal beams, a nail strip being provided between the free ends of the legs of the U-profile, the legs of the profile comprising an inwardly extending support edge directly below the nail strip for supporting said nail strip.
  • the part of the K-shaped end parts which is extending about horizontally will be positioned out of the height of the beam so that the upper surface of the beam may comprise two different positions in respect of the upper surface of the primary beam.
  • the profiles can be connected to the form plate in a simple way. In this way form panels can be shaped which may fast be laid down on the primary beams.
  • the support system shown in Fig. 1 comprises the posts 1, being composed of the parts 2, 3 and 4.
  • the parts 2 are shaped by screw jacks which in a not further indicated way consist of a spindle over which a nut is rotatable so that the lower ends of the tube parts 3 of the posts can be brought at the same height and can be connected to each other by means of the horizontal connections 5. Further the diagonal rods 6 can be provided to obtain a stable construction.
  • the part 4 is shaped by a drop head, the construction of which is further described by means of the Figs. 4 - 6.
  • Fig. 1 shows the application of primary beams 7 with various lengths, all at the circumstances bring along with them.
  • a support 8 can be mounted on which a guard rail construction 9 can be placed.
  • a primary beam is supported at some distance from its end and so is partly cantilevered in which case use can be made of wooden beams or such like instead of a drop head. This, however, will be obvious for an expert.
  • Fig. 2 again shows the upper ends of some posts 1 with the screw jacks 2 and the drop heads 4 serving to support primary beams 7 between which dominanty beams 10 are provided.
  • Fig. 3 shows a plan view of some primary beams 7 between which excludey beams 10 are provided which may serve to support form plates 11.
  • Fig. 3 shows only a part of one form plate 11. The possibility also exists that a form plate 11 is fixedly connected to e.g. two propely beams as will be described afterwards. Then a form panel 26 may be obtained.
  • the drop head 4 shown in the Figs. 4, 5 and 6 comprises a base plate 12, being connected to a drop plate 13, indicated by dash-lines, of a screw jack 2.
  • the base plate 12 of the drop head 4 is connected to a square tube 14 in which a radially extending round pin 15 is fixed.
  • the pin 15 serves to support a nut 16 the lower surface 17 of which is partly helically shaped so that when rotating the nut 16 this will be moved over a given distance in vertical direction. Further the nut 16 is provided with an inner recess 18 so that the nut, after being rotated to its lowest position, may drop down along the pin 15.
  • the drop plate 19 On the nut 16 the drop plate 19 is lying comprising the support surface 20 and the lips 21 extending obliquely upward from it.
  • the drop plate 19 is provided with a square opening, not further indicated, so that it is only movable in vertical direction along the tube 14 and cannot be rotated in respect of this.
  • the tube 14 is further provided with an abutment sleeve 22, said sleeve having a square section as well as the tube 14.
  • the upper end of the tube 14 is provided with the front plate 23.
  • the upper surface 24 of the front plate 23 may be aligned with the upper surface 25 of the form plates 11, so that afterwards it will directly support the cast concrete flooring. Also the possibility exists that the upper surface 24 of the front plate 23 serves to support the wooden form plate 11. In this case the form plates 11 will be present as long as the posts 1 cannot be removed. See also the Figs. 1-3.
  • Figs. 7 and 8 show a part of a primary beam 7 being formed by an aluminium profile 27 obtained by extrusion, the lower part of which is baffled near the end 28.
  • an end part 30 is fixed by means of rivets 31 in the upper tubular part 29 of the profile.
  • the end part 30 is provided with a recess 32 for receiving a lip 21 of the drop plate 19 in it, as shown in Fig. 4.
  • the lip 21 will engage a lower rim 33 forming part of the end part 30.
  • the support rims 34 of the aluminium profile 27 are provided with upwardly extending rims 35 for supporting transity beams 10, as these are indicated in Fig. 2 and will be described afterwards by means of the Figs. 12-17.
  • the Figs. 9-11 show a primary beam 7 being composed of steel profiles, to wit the mainly U-shaped profile 36 comprising the upper plane 37 and the side planes 38 which at their free ends are bended to form a support rim 39 which in turn is bended to form an upwardly extending rim 40 being provided with the rolled reinforcing rim 41.
  • the end part 42 is provided within the beam at its end, said part 42 at its lower end being provided with a recess 43.
  • a reinforcing strip 44 is present being connected to the parts 39 and 40 such that a recess 45 is obtained for receiving a lip 21 of the drop plate 19, see Fig. 4.
  • the safety plate 46 is provided which prevents that the upper end of the beam 7 is moving towards the tube 14, see Fig. 4, of a drop head 4 when the lower end of the end part 42 engages the abutment sleeve 22.
  • a strip 47 is mounted in the end part 42 and serving for connecting a T-profile 48 extending obliquely down­wardly as in particular appears from Fig. 9 and which together with a vertical profile 49 is forming a reinforce­ment of the profile 36.
  • Figs. 12-14 show a leadery beam fabricated from an aluminium profile 50 being obtained by extrusion and being mainly U-shaped and comprising the body 51 with the legs 52 extending from it. Between the ends of the legs 52 a nail strip 53 is provided which can be fixed by means of some pop rivets 54. Further the nail strip 53 is supported by the inwardly extending support rims 55 of the profile 50.
  • the ends of the profile 50 are provided with end parts 56 being mainly K-shaped and comprising a flange 57, a connecting piece 59 extending mainly horizontally from it and two support lips 59. Because the connecting piece 58 is not positioned in the middle of the height of the profile 50, the propely beam 10 can be laid down onto the support rims 35 or 40, see the Figs. 8 and 11, of a primary beam 7 in two different manners such that the upper surface of the propely beam may be positioned at different levels in respect of the upper surface of the primary beams 7.
  • the startery beam 10 according to the Figs. 15-17 mainly corresponds with that according to the Figs. 12-14.
  • the beam comprises a U-profile 60 being obtained by bending steel plate.
  • a nail strip 53 is present again between the legs of the U-profile and being fixed by means of pop-nails 54 and being supported by support rims formed by inwardly extending portions of the legs of the U-profile.
  • the ends of the U-profile 60 are connected to the end parts 61 which are executed in a corresponding way as the end parts 56, but now are provided with a part 62 welded to it and being extended inwardly into the profile 60 and being connected to the profile by means of pop-nails 63.
  • end part 56 can be provided with a portion extending inwardly in the profile and that the end part 61 can be connected to the profile 60 directly by means of the flange plate.
