Definitions

  • the invention relates to a support structure for transferring a permissible compressive force between 100 kN and 1000 kN each of a stand of the support structure that can be set up on the floor, the support structure having a connector, at least two bolts and a plurality of bolts, the at least two bolts each having at least one bolt are reversibly detachably arranged on the connector.
  • Supporting structures for such a medium load range. Supporting structures of this type are used to support loads, for example to support formwork for concreting a building.
  • supporting structures are composed of individual, reversibly connectable parts in a modular manner.
  • a main component of the supporting frameworks are bars, which are indirectly connected to each other via connectors.
  • GB 1 441 953 A describes a steel girder which is made up of belt elements and diagonal elements which are connected by plates, and the belts are reinforced by strips at the load points.
  • the straps are U-shaped in cross-section, and the reinforcement members are flat and evenly spaced holes are provided along their entire lengths to allow connection by bolts.
  • GB 1 441 953 A discloses the features of the introductory part of claim 1.
  • the object of the present invention is to provide a supporting structure, the components of which are significantly easier to handle with the same load capacity.
  • the object of the invention is thus achieved by a supporting structure for the medium load range.
  • the support structure according to the invention is an essentially rod-shaped structure for carrying a load with at least two bolts, at least two bolts and at least one connector. At least two bolts are each arranged on a connector by 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 transom height is measured perpendicular to the longitudinal axis of the transom.
  • the bolt height is also measured perpendicular to the longitudinal axis of the at least one bolt that connects the bolt to the connector.
  • the wall thickness of the two bars and / or the connector is substantially reduced by using a steel with an upper yield strength of more than 490 MPa.
  • the wall thickness is preferably less than 10 mm, in particular less than 8 mm, particularly preferably less than 7 mm.
  • the bolts of the supporting structure preferably have through-recesses for receiving bolts.
  • the majority of the bars of the supporting structure are preferably made of a steel which has an upper yield strength of more than 490 MPa. More preferably, the majority of the bars of the supporting frame each have a maximum bar height of less than 200 mm.
  • the support structure is designed to absorb a compressive force between 200 kN and 600 kN each of a stand that can be set up on the floor.
  • the supporting scaffold according to the invention is thus located between a light supporting scaffold - for example a facade scaffold - and a heavy supporting scaffold - for example for supporting formwork for large bridges.
  • the at least two bars can be made of steel with an upper yield strength of more than 540 MPa and a bar height of less than 120 mm.
  • the bars are particularly light and easy to handle.
  • the majority of the bars of the supporting structure are preferably made of steel with an upper yield strength of more than 540 MPa. More preferably, the majority of the bars of the supporting frame each have a maximum bar height of less than 120 mm.
  • the at least two bars can each have two U-profiles, which are located indirectly on the central floor areas of the U-profiles connected to each other, in particular welded together.
  • the connector can be plate-shaped and can be inserted in sections between the U-profiles.
  • the connector is preferably essentially in the form of a plate with a semicircular contour.
  • the connector may be in another shape, such as an angled shape.
  • the connector can be designed, for example, to establish an angled connection, in particular a 90 ° corner.
  • the plurality of bolts of the supporting frame each have two U-profiles, each pair of U-profiles being connected to one another indirectly at the central bottom regions of the U-profiles.
  • the connector can have at least seven essentially semicircular coupling points for connecting a latch to the connector.
  • the coupling points are preferably each offset by 30 ° to an adjacent coupling point.
  • the coupling points are designed in particular in the form of passage recesses for receiving the bolts. Since, in the prior art, as a rule six screw bolts are used to connect a single bolt to the connector, only four coupling points have so far usually been formed on a semicircular connector for reasons of space.
  • the majority of the connectors of the supporting frame each have at least seven coupling points for arranging a bolt with the respective connector.
  • At least a part of the at least two bars is preferably rolled, ie manufactured using the rolling method. Due to the at least partial production of the at least two bars in a rolling process, high-precision manufacture of the bars is achieved. In contrast, the bars are generally rolled in the prior art, whereby the inventive Advantages are only very limited or can only be achieved with increased post-processing of the bars. In particular, the at least two bars are completely rolled. It is further preferred that the majority of the bars of the supporting structure are rolled, in particular completely in each case.
  • the at least two bolts in their area in engagement with a bolt each have a bolt diameter of more than 20 mm, the at least two bolts each being connected to the connector by fewer than five bolts of the supporting structure.
  • the load capacity of the supporting structure known from the prior art can be obtained by using a few bolts, the supporting structure being much easier to assemble and disassemble due to the significantly lower number of bolts used.
  • the plurality of bolts are each connected to a connector by less than five bolts. More preferably, the majority of the bolts each have a bolt diameter of more than 20 mm.
  • the at least two bolts more preferably have a bolt diameter of at least 30 mm.
  • the majority of the bolts of the supporting structure preferably have a bolt diameter of at least 30 mm.
  • the at least two bolts are each in the form of a plug pin.
  • the socket pins preferably each have a split pin. Bolts can be assembled and disassembled much faster than screws. Furthermore, it is immediately apparent through the safety pins whether the bolts are correctly arranged or not, since the safety pins are only correct arranged bolts are attachable. In contrast, it cannot be easily assessed optically with a screw connection whether the screw connection is securely mounted or not.
  • the at least two bolts are each designed in the form of a fitting bolt.
  • the fitting bolts enable a particularly rigid construction of the supporting structure.
  • the use of fitting bolts is made possible in particular by the use of steel for the bolts with an upper yield strength of more than 490 MPa.
  • the at least two latches are particularly preferably each arranged on the connector by two bolts.
  • the two bolts represent a particularly easy to assemble and disassemble the bolt with the connector, while maintaining mechanical stability.
  • the bolts mentioned are in the form of socket pins and in the form of fitting bolts. More preferably, the plurality of bolts are each arranged on a connector by two bolts.
  • the supporting structure can have at least one truss.
  • the truss has a plurality of latches and a plurality of connectors previously described.
  • the width of the truss essentially corresponds to the width of the bars.
  • the truss height measured perpendicular to the longitudinal direction is preferably more than 2200 mm.
  • the truss height is particularly preferably more than 2400 mm. In the prior art, the truss height is typically 2000 mm. Due to the significantly larger truss height, the transom height can be chosen significantly smaller than in the prior art, so that the truss still has the same resistance to buckling loads.
  • the supporting structure is designed in the form of a bridge.
  • the bridge preferably has at least one truss, in particular a plurality of trusses.
  • the supporting structure can have vertical trusses.
  • the supporting structure can be designed in the form of a tower.
  • the tower preferably has at least one truss, in particular a plurality of trusses.

  • the standing areas each have a side length L S between 1000 mm and 2000 mm.
  • the height H G of the scaffolding towers is up to 25000 mm.
  • the span W W of the bridge 10 is up to 25000 mm.
  • the bridge has at least one truss 14 , which is arranged between the scaffolding towers 12a-b.
  • the bridge 10 preferably has a plurality of truss girders 14 arranged parallel to one another, which are arranged between the scaffolding towers 12a, 12b.
  • the truss height F H of the truss 14 is preferably 2500 mm.
  • the longitudinal axis of the truss 14 is in Fig. 1 marked with the reference number 15.
  • the scaffolding towers 12a, 12b have scaffolding posts 16a, 16b, 16c, 16d supported on the ground.
  • the bridge 10 is designed to remove a permissible compressive force of up to 400 kN via the scaffold posts 16a-d.
  • Bridge 10 shown schematically, is therefore a supporting structure 18 for a medium load range.
  • Fig. 2 shows a section 20 Fig. 1.
  • Fig. 2 is an example of a node of the truss 14 (see Fig. 1 ).
  • Fig. 2 shows a connector 22.
  • the connector 22 is plate-shaped and has a semicircular shape.
  • Bolts 24a, 24b, 24c, 24d are arranged on the connector 22.
  • the bolts 24a-d are arranged on the connector 22 via bolts 26a, 26b, 26c, 26d, 26e, 26f, 26g, 26h .
