Definitions

  • the invention relates to a supporting framework for bearing an allowable pressure force of between 100 and 1,000 kN per scaffolding post of the supporting framework that can be arranged on the ground, wherein the supporting framework comprises a connector, at least two bars, and a plurality of bolts, wherein the at least two bars are arranged on the connector so as to be reversibly releasable through in each case at least one bolt.
  • Supporting frameworks for such a medium load range are well known. Supporting frameworks of this type are used to support loads, for example, to support formwork into which concrete is poured to construct a building.
  • supporting frameworks are assembled in a modular manner from individual parts that can be reversibly connected to one another. Bars that are connected indirectly to one another via connectors constitute a major component of the supporting frameworks.
  • the present invention addresses the problem of providing a supporting framework that has components which are significantly easier to handle with the same load capacity.
  • the problem according to the invention is thus solved by a supporting framework for the medium load range.
  • the supporting framework according to the invention then entails a substantially rod-shaped structure for bearing a load with at least two bars, at least two bolts and at least one connector. At least two bars are arranged on a connector, through in each case at least one bolt.
  • the bars are made of steel.
  • the steel has an upper yield strength of more than 490 MPa.
  • the bar height is less than 200 mm.
  • the bar height is then measured perpendicular to the longitudinal axis of the bars.
  • the bar height is furthermore measured perpendicular to the longitudinal axis of the at least one bolt that connects the bar to the connector.
  • the wall thickness of the two bars and/or the connector is significantly reduced by the use of a steel that has an upper yield strength of more than 490 MPa.
  • the wall thickness is preferably less than 10 mm, in particular less than 8 mm, especially preferably less than 7 mm.
  • the bars of the supporting framework preferably have through recesses for receiving bolts.
  • the plurality of bars of the supporting framework are preferably composed of a steel that has an upper yield strength of more than 490 MPa. Further preferably, the plurality of bars of the supporting framework each have a maximum bar height of less than 200 mm.
  • the supporting framework is designed to bear a pressure force of between 200 and 600 kN per scaffolding post that can be set up on the ground.
  • the supporting framework according to the invention is thereby positioned between a lightweight supporting framework—e.g., a façade framework—and a heavy supporting framework—e.g., for supporting formwork for large bridges.
  • the at least two bars may be composed of a steel having an upper yield strength of more than 540 MPa, and a bar height of less than 120 mm. This makes the bars especially light and easy to handle.
  • the plurality of bars of the supporting framework are preferably composed of a steel that has an upper yield strength of more than 540 MPa. Further preferably, the plurality of bars of the supporting framework each have a maximum bar height of less than 120 mm.
  • the at least two bars may each have two U-profiles that are indirectly interconnected—in particular, welded to one another—at the central bottom regions of the U-profiles.
  • the connector may then be plate-shaped and be accommodated in some sections between the U-profiles.
  • the connector is preferably configured substantially in the form of a plate having a semicircular contour.
  • the connector may be configured in another form, for example, an angled form.
  • the connector may be configured, for example, for the construction of an angled connection, in particular, a 90° angle.
  • the plurality of bars of the supporting framework preferably each have two U-profiles, wherein each pair of U-profiles is respectively indirectly interconnected at the central ground regions of the U-profiles.
  • the connector may have at least seven coupling points arranged in a substantially semicircular manner in order to connect a bar to the connector.
  • the coupling points are then preferably offset in each case by 30° from an adjacent coupling point.
  • the coupling points are configured, in particular, in the form of through recesses for receiving the bolts. Because six screw bolts are generally used in the prior art in order to connect a single bar to the connector, typically only four coupling points have conventionally been configured on a semicircular connector, for space-related considerations.
  • the plurality of connectors of the supporting framework preferably each have at least seven coupling points for arranging a bar with the respective connector.
  • At least a part of the at least two bars is preferably rolled, Le., produced by rolling.
  • the at least partial production of the at least two bars by rolling method achieves high-precision manufacturing of the bars.
  • the bars are generally rolled, which makes it possible to achieve the advantages according to the invention only to a very limited degree or only with increased post-processing of the bars.
  • the at least two bars are completely rolled.
  • the plurality of bars of the supporting framework are rolled, in particular, each completely.
  • the at least two bolts each have a bolt diameter of more than 20 mm in the region thereof that engages with a bar, wherein the at least two bars are each connected to the connector by fewer than five bolts of the supporting framework.
  • the plurality of bars are preferably each connected to a connector by fewer than five bolts. Further preferably, the plurality bolts each have a bolt diameter of more than 20 mm.
  • the at least two bolts have a bolt diameter of at least 30 mm.
  • the plurality of bolts of the supporting framework preferably have a bolt diameter of at least 30 mm.
  • the at least two bolts may be configured in the form of screws.
  • the at least two bars are preferably each configured in form of a plug-in bolt.
  • the plug-in bolts preferably each have a safety splint. Plug-in bolts can be assembled and disassembled much faster than screws.
  • the safety splints make it possible to immediately determine visually whether the bolts have been arranged correctly or not, because the safety splints can only be fastened when the bolts have been arranged correctly. In contrast thereto, a screw connection does not readily allow for visual inspection of whether the screw connection has been securely assembled or not.
  • the at least two bolts are each configured in the form of a fit bolt.
  • the fit bolts allow for an especially rigid construction of the supporting framework.
  • the connection of fit bolts is made possible, in particular, by the use of a steel for the bars that has an upper yield strength of more than 490 MPa.
  • the at least two bars are each arranged on the connector by two bolts.
  • the two bolts constitute a connection of the bar to the connector that is especially easy to assemble and disassemble, wherein the mechanical stability is maintained.
  • the aforementioned bolts are preferably designed in the form of plug-in bolts, in particular, in the form of fit bolts.
  • the plurality of bars are each arranged on a connector by two bolts.
  • the supporting framework may comprise at least one lattice truss.
  • the lattice truss has a plurality of previously-described bars and a plurality of previously-described connectors. The width of the lattice truss therefore substantially corresponds to the width of the bars.
  • the lattice truss height as measured perpendicular to the longitudinal direction is preferably greater than 2200 mm. Especially preferably, the lattice truss height is greater than 2400 mm. In the prior art, the lattice truss height is typically 2000 mm. The significantly greater lattice truss height makes it possible to select a still considerably smaller bar height than in the prior art, such that the lattice truss still has the same resistance to a buckling load.
  • the supporting framework is configured in the form of a bridge.
  • the bridge preferably has at least one lattice truss, in particular, a plurality of lattice trusses.
  • the supporting framework may comprise vertically-standing lattice trusses.
  • the supporting framework may be configured in the form of a tower.
  • the tower then preferably has at least one lattice truss, in particular, a plurality of lattice trusses.
  • FIG. 1 illustrates a plant view of a bridge according to the invention, with a lattice truss according to the invention
  • FIG. 2 illustrates a section from FIG. 1 that shows a connector with four bars arranged thereon;

  • FIG. 4 illustrates a section view of a bar from FIG. 3 along the line IV-IV.
  • FIG. 1 illustrates a bridge 10 .
  • the bridge 10 comprises scaffold towers 12 a, 12 b.
  • the scaffold towers 12 a - b span a square base.
  • the bases each have a side length L s of between 1000 and 2000 mm.
  • the height H G of the scaffold towers is up to 25000 mm.
  • the span S w of the bridge 10 is up to 25000 mm.
  • the bridge has at least one lattice truss 14 that is arranged between the scaffold towers 12 a - b.
  • the bridge 10 has a plurality of lattice trusses 14 that are arranged in parallel to one another and are arranged between the scaffold towers 12 a, 12 b.

  • the scaffold towers 12 a, 12 b have scaffolding posts 16 a, 16 b, 16 c, 16 d that are supported at the bottom.
  • the bridge 10 is configured in order to support an allowable pressure force of up to 400 kN via the scaffolding posts 16 a - d.
  • the bridge 10 which is schematically represented in FIG. 1 , therefore involves a supporting framework 18 for a medium load range.

  • FIG. 3 illustrates the section 20 according to FIG. 2 with the connector 22 , but without the bars 24 c, 24 d arranged on the connector 22 (see FIG. 2 ).
