Definitions

  • the invention relates to a box girder for a double-girder overhead crane, comprising a profile girder upper chord of high rigidity, a lower chord and two web plates connected to the upper chord and the lower chord by welds to form a trapezoidal hollow box profile in particular (DE-A-30 16 721).
  • girders for bridge cranes As a hollow box section with a rectangular but also trapezoidal cross section. Top flange, bottom flange and web plates are connected by welds.
  • bulkhead plates are welded into the hollow box profile for stiffening at certain intervals (DE-B-24 55 968). While the weld seams for connecting the web plates to the upper and lower flange can be carried out mechanically, the bulkhead plates have to be welded in by hand. This is a tedious, time-consuming and ultimately ultimately costly activity.
  • a box girder for a gantry crane which does not require stiffening bulkhead plates. It is a two-cell box girder with a cross-sectional profile, the upper cell of which contains a double-T profile girder.
  • the web plates are welded to both the top flange of the double-T profile beam in the area of the profile web and to the edge of the bottom flange of the double-T profile.
  • the lower flange of the box girder delimits the lower cell downwards.
  • T-section beams in a box girder of a gantry crane is known per se from DE-B-24 55 968.
  • box girder triangular bending profile girders are inserted between a running rail and a web plate on the longitudinal edges of the upper flange of the box girder.
  • Each of the two bending profile supports comprises a T-shaped profile rail which is welded together via two short web plates to form a triangle forming the support corner.
  • the well-known box girder is also multicellular and is braced by transverse bulkhead plates.
  • the upper chord consists of a T-section beam, in particular a T-section beam.
  • a profile carrier is an open and therefore inexpensive profile, which due to the loads introduced by sprockets into the upper flange essentially at points its high bending stiffness is distributed over a larger area than line loads, so that the web plates lying under the top flange are not bulged and bulkhead plates and, if necessary, bracing are unnecessary. Since the upper chord consists entirely of the T-section beam, no welds need to be made inside the box girder. Another advantage is the relief of the weld between the top flange and the web plate.
  • the sloping web plates 1 have the advantage that the upper flange 3 according to FIG. 2 participates in the deformation in the event of lateral forces and thus counteracts the deformation with a reaction force.
  • the trapezoidal shape assumes the shape shown in broken lines in FIG. It can be seen that the upper flange 3 rotates by the angle ⁇ relative to the undeformed region of the upper flange 3. This results in a Reaction torque of the upper chord 3, which counteracts a deformation by the side force 7 shown with an arrow.
  • the trapezoidal shape results in a shape that is particularly rigid against twisting due to lateral forces.
  • the box girder according to the invention can also be designed with parallel web plates, which was not explicitly shown.
  • a rail 8 can be welded onto the upper flange 3 (FIG. 3).
  • Stage attachments 9 or the like are usually to be attached to the box girder. It is advantageous according to FIG. 4 to fasten it to the lower flange 2 by means of a continuous cross bar 10 through first and second weld seams 11 and 12, the weld seams being provided directly under the longitudinal weld seams 13 which connect the lower flange to the web plates 1.
