Definitions

  • This invention relates to a decking system comprising longitudinal beams supported by variable height support standards, to which cross beams and decking panels are coupled, in which system the upper surfaces of the longitudinal beams, the cross beams, the topplate of the drophead and the panels together form a decking surface for concrete, in which the longitudinal beams represent a profile having a topplate and a lower supporting flange at both longitudinal sides of this beam, wherein the flanges are each provided with a longitudinal raised edge over which the cross beam at its hooked end is hooked for interconnection of the beams and moreover these supporting flanges are formed so as to support the panel at its circumferential rim.
  • Such a system belongs to a generally known state of art for constructors of concrete building floors.
  • the mutual distance between the cross beams can be chosen at will in order to adapt the distance of support of the form panel to the weight of the supported concrete and the structural strength of the form panel.
  • This can simple take place by a structure enabling the cross beams to be hooked down upon a raised edge provided along both supporting flanges of the longitudinal beams.
  • the known system has several disadvantages.
  • the longitudinal beams are unsuitable for supporting panels because of the presence of the raised edge which constitutes a hindrance to the panel rim. Besides, this edge builds a kind of a gutter which is easily clogged by concrete, leaking through the joint between a longitudinal beam and a panel. While using the previously mentioned system using panels, mostly such panels are hooked down with their rim upon projections, being provided on the supporting flanges of the support beam.
  • the above decking system is characterised in that the raised edge is located between the vertical centre line of the longitudinal beam and the vertical projection of the external longitudinal edge of the top plate of this beam and that the supporting flange of this beam extends beyond said vertical projection.
  • FR-A-1406027 shows a longitudinal beam having openings into which the hookformed beam's end can be inserted so as to couple the beams.
  • this specification there is no longitudinal beam forming a gutter and no teachings are given on a possible provision of accomodating panels as such.
  • An adjustable head is known itself from GB-A-1483667 which has a feature whereby this head is provided with an overlying top plate and which has holding means in which a pin of a beam can be moved in a groove so as to let the head to rotate relative to the beam. Provisions how to arrange the gutter of a longitudinal beam in such a way that no leakage of concrete can occur if the top of the structure is provided with concrete, are not availabele.
  • the supporting flange in the system according to the invention is provided with elements over which the rim of the frame of the panel can be attached to the beam.
  • the longitudinal beam 1 is supported at both ends by a drophead 2 .
  • the longitudinal beam 1 is at both ends provided with a recess fitting over a protrusion 13 on the drophead 2 thereby obtaining a required structural longitudinal strength.
  • the dropheads 2 are fitted upon decking standards, stuts or props.
  • Both the longitudinal beam 1 and the drophead 2 are provided on both sides with a supporting flange 3 for supporting form panels 4 .
  • the supporting flanges 3 are provided with locking means 5 .
  • the longitudinal beam 1 and the drophead 2 are on both sides provided with a continuous raised edge 6 .
  • the cross beam 7 hooks down with its hook 8 behind the raised edge 6 giving thereby sufficient structural strength to the decking system. Since the raised edge 6 runs in a continuous way along the entire length, the cross beams 7 can be located at any desired position for supporting the form panel 14 most economically and also to take care of the structural joint between the longitudinal beams 1 and the cross beams 7 .
  • the longitudinal beam 1 and the drophead 2 are each provided with a top flange 9 and a top plate 10 respectively which extend beyond the raised edges 6 . This prevents as much as possible any leakage of concrete through the seam or joint 11 reaching the gutter 12 . Moreover the circumferential panel edges are not obstructed by the raised edge 6 .
  • the longitudinal beam as described can be manufactured from aluminium by the extrusion process enabling easy handling by its low own weight. It may be clear however that although reference has been made in the description to a continuous raised edge 6 , also a discontinuous raised edge could be used to establish sufficient structural strength between the longitudinal and cross beams respectively.
  • the cross beams 7 are provided with recesses which enable their hooking down upon the raised edges 6 ; nevertheless the supporting flanges may also be provided with recesses or openings to replace the raised edge whereas the cross beams may be provided with protruding hooks or noses for hooking on.
