Definitions

  • the invention relates to a combination of a cross member and a side member, the side member being provided on both sides with a support flange having a raised edge and an upper flange which projects laterally with respect to the vertical web of a side member, the cross member at least at one longitudinal end is provided with a hook-shaped end to the hook over the upstanding edge of the side member and wherein the end of the cross member is designed such that this member can be hooked over the edge of the supporting flange of the side member in a first tilt position rotated about its longitudinal axis and through Rotation about its longitudinal axis can be brought into a second tilt position.
  • Such a construction is known from US-A-4586841. Such a construction is used for hanging a suspended ceiling in buildings.
  • this cross member can have such freedom of movement upwards that it can get out of position. This can occur in particular if a cross member has only been mounted in one side member at one end and the other end freely projects on a steel tube support. This can lead to undesirable situations for the people on the floor formwork panels.
  • the invention now aims to provide a construction in which the cross member can no longer get out of position with respect to the longitudinal member, as a result of which an even greater level of safety is generally obtained for the people on this support construction, and this construction is also particularly suitable to arrange a cross member in a clearly secured manner between two attached, parallel side members.
  • support for a slab formwork is formed from a grid of side members 1 and cross members 2.
  • the whole is held at a certain height by, for example, steel pipe supports, not shown, and is covered by formlining.
  • the longitudinal member has a web with a continuous support flange 5 on both sides with a raised edge 6.
  • the cross member 2 has an end which is provided with a hook-shaped head 15 which can hook around the raised edge 6 of the side member (FIG. 5).
  • the cross member remains in position in that the end 7 is located below the protruding flange 9 of the side member.
  • the formwork will have to protrude at the edge of a concrete slab to be arranged so that a front formwork and railing posts can be arranged.
  • a front formwork and railing posts can be arranged.
  • the longitudinal beams over a support in the form of a beam with e.g. Cantilever steel tube supports If the cross member were not secured upwards in the area of the side member, there could be a risk that the cross member tilts out of the side member, with all the consequences thereof for those below and on the ceiling.
  • the crossbeams must be placed at any arbitrary location in a longitudinal beam or, for example, between two already arranged Side rails can be placed. Due to its design, the cross member end 7 cannot be hooked in a horizontal position between the upstanding edge 5 and the protruding upper flange 9 of the side member. If the cross member is only to be hooked into a longitudinal member at one end (see FIG. 2), then this can be carried out in the manner according to FIG. After the cross member is hooked at one longitudinal end, the other end is raised according to arrow X. Once in a horizontal position, the connection is automatically secured.
  • a cross member can be used according to the invention, which is shaped such that it can be brought into a first position rotated about its longitudinal axis and in a horizontal plane between the webs of the two nearest side members ( Figure 3 , 3a) and then secured by rotation about its longitudinal axis between the upper flange 9 and lower edges 6.
  • the cross member 2 is on its end face with a securing part of a e.g. provided from the figure 6 form.
  • the selected solution has a cross member 2, which has an end plate 15 with a rectangular triangular shape, which has a long side 11 and a short side 10.
  • the cross member 2 In a first rotated position, the cross member 2 is hooked with its long side 11 over the edge 6 of the supporting flange 5 of the side member 1, and by turning the cross member 2 about its longitudinal axis, the upright long triangular side 11 becomes the cross member in the side member 1 between the edge 6 and secure the upper flange 9.
  • the end plate of the cross member hooks with its short rectangular side 10 over the edge.
  • the cross member end can be fastened to the cross member with, for example, a bolt connection 16.
  • a bolt connection 16 By adjusting the position of the cross member 2, the upper side of the cross member now moves into a different plane.
  • the illustrated Embodiment has only one connecting bolt 16, whereby (by rotating the end 7 by 180 ° about the longitudinal axis of the cross member) between two different levels of the cross member 2, can be selected with respect to the upper side of the longitudinal member.
  • the location of the connecting pin 16 is selected such that the upper surface of the cross member 2 is in the same plane as the surface of the side member 1.
  • the cross member 2b By loosely turning the connecting bolt and rotating the cross member 2 about its longitudinal axis through an angle of 180 °, the cross member 2b is now obtained with the upper side in a lower plane than the upper side of the cross member 1.
  • the formwork panel In the area of cross member 2a, the formwork panel can be placed on the side members and cross members. With the cross member 2b, a formwork panel can be placed between the longitudinal members, which panel has a thickness such that the upper side of the formwork panel lies in the same plane as the upper side of the longitudinal member 1, so that a flat formwork surface is obtained.
  • the invention is not only limited to use with longitudinal members that are already firmly arranged parallel to one another. It is also used for hooking a crossmember end into a side member, the other end of a crossmember being finally brought to the same height as the first end from a lower level after hooking in the first end. In the end position, the cross member end is also secured in the side member.
