Definitions

  • the invention relates to a formwork support with a first belt element made of a wood material, a second belt element made of a wood material, a web element connecting the first belt element with the second belt element, and with a tilt protection element for tilt protection of another formwork support.
  • the invention relates to a formwork construction, which is particularly adapted for the production of a ceiling, with at least one formwork support and a transverse thereto arranged further formwork support.
  • the slab formwork system has a plurality of yoke beams, which are supported on supports. Above transverse cross member are arranged. To secure the cross member against tipping over a tilt protection is provided.
  • the anti-tip device has two prongs, which are attached to a mounting body. Thus, a receptacle is formed, in which a single cross member can be arranged in the upright state.
  • the anti-tip device also has upper projections which can be hung on the upper strap of the yoke carrier. At the lower end of the anti-tip device, a lower projection is provided, which engages under the lower belt of the yoke carrier.
  • a receptacle is provided, in which a tool can be inserted.
  • the anti-tip device is first placed in an inclined state and then pivoted.
  • the cross member can be used before or after attaching the anti-tip device to the yoke carrier.
  • the holding device is designed as a one-piece retaining clip which connects the upper flange of the support profile with the lower flange of the support profile.
  • the holding device On the underside, the holding device has a coupling section into which a tool can be inserted.
  • Kippschommen for generic formwork beams are in the DE 103 59 761 A1 .
  • the US 2002/0020799 A1 describes the connection of intersecting formwork beams.
  • mounting rails are attached to the side surfaces of at least the upper formwork support. Below the mounting rail a recess is provided.
  • the mounting rail allows the arrangement of a fastener which can be connected to the underlying formwork support.
  • the disadvantage of this is in particular that the mounting rails must be externally attached to the side surfaces of the upper formwork support. As a result, on the one hand, the dimensions of the formwork support are changed. On the other hand, the removal of the tilting moments of the upper formwork support to the lower formwork support is not optimally solved.
  • the fastener must bridge a comparatively large distance between the attachment points on the formwork beams.
  • a further disadvantage of this prior art is the comparatively complicated attachment of the fastening means to the mounting rails.
  • the fastening means are composed of several individual parts, which require a relatively complicated handling.
