Definitions

  • the invention relates to a dome beam designed as a lattice girder for the leading dome heading in the tunnel partial excavation method, which can be connected at its one end by means of a connection to the free end of the dome foot foremost in the heading with respect to vertically downward and laterally directed forces and at both ends depending on the bending moment has a protruding end plate in the form of the web of a U-profile piece, the legs of which are welded to the strut bars, while a connecting member projects rigidly from a support end perpendicularly over the end plate and a passage opening for one on the Backside of the support end plate of an adjacent dome foot supporting wedge.
  • bending moment rigidly connectable dome foot beams are known, which, however, are not designed as lattice girders.
  • a lattice girder of the type described at the outset is known from DE-A-30 14 402, but is used in tunnel construction as part of arched stiffening elements.
  • connection coupling of the known lattice girder now has several disadvantages.
  • the U-profile pieces which have to be welded between the belt bars of the lattice beam ends, have to be processed in different ways. While one U-profile piece has to be provided with three holes, whereby a round bar eyelet has to be welded into two of these holes, the second U-profile piece must also have a hole and an elongated hole, which can only be produced by milling, burning out or punching out. In addition to the resulting significant costs, the elongated hole considerably reduces the strength of the U-profile web. In addition, however, the workflow when connecting two lattice girder ends is also cumbersome.
  • the round rod eyelet welded into one U-profile piece must be inserted through the elongated hole of the other profile piece and temporarily wedged on its back until the final connection of the beam ends is then established by means of a screw bolt to be tightened with wrenches, each through a hole in the web of the Profile pieces must be inserted, which assumes that these holes are pretty much aligned.
  • the handling is extremely restricted and therefore difficult to carry out in the very cramped area in which such a bolt has to be inserted and tightened during the advancing dome drive.
  • the object of the invention is to create such a lattice girder in which the connecting elements of the girder ends to be connected to one another are very simple and, in the process, are designed in such a way that by driving in clamping wedges a direction that is particularly accessible at the place of use, the exact, final connection is immediately established, which results in the bending stiffness in the required directions and the torsional stiffness.
  • the dome foot beams according to the invention is considerably simplified compared to the conventional one, since only from above, where sufficient space has already been cleared during the leading dome drive, only two clamping wedges need to be driven in to make the final connection, whereby the holes according to the invention are arranged in the Connection plate also ensures an exact alignment of the newly attached lattice girder with respect to the previous one.
  • the two clamping wedges also provide a high bending strength with regard to horizontally acting forces and also a high torsional strength, since the inserted clamping wedges are supported on the inside of the legs of the U-profile pieces. This is ensured by the hole spacing design according to the invention.
  • connection coupling is also easier to manufacture.
  • the U-profile pieces do not require any processing. Only two additional holes for the clamping wedges are to be drilled in the connecting plate.
  • the advantage of simplicity in the handling of the dome foot beam according to the invention under the more difficult working conditions at the place of use is supplemented by the further advantage that, on the one hand, through the characterized hole spacing, precise alignment in the lateral direction as well as the desired torsional rigidity through the application of the clamping wedge bolts on the inside of the U -Profile leg is guaranteed, while the vertical support of the connection point on the one hand and on the other hand, a counter bearing for the friction forces occurring when the clamping wedges are given by the mounting bracket.
  • the dome foot bar of FIGS. 1 and 2 designated in its entirety by 10, has a rectangular cross-section with four belt bars running at the edges, the upper one designated 11a and the lower one 11b. These belt rods are connected to one another by lattice reinforcements 12 welded to them. At both ends are slightly above the ends of the belt rods Ila, Ilb protruding, perpendicular to them support end plates U-profile pieces 13, 14 welded between the belt bars that one leg 13b, 14b of the U-profile pieces 13, 14 an upper and connects a lower belt rod 11 a, 11 b together.
  • the webs 13a, 14a represent the carrier end plates.
  • the one U-profile piece 14 is stiffened in its interior by welded-in plates 15, which connect the ends of the legs 14b to the center of the web 14a.
  • a connecting plate 16 is welded onto the upper end of the other U-profile piece 13, which is also welded to the upper belt rods 11a and protrudes away from the lattice girder over the carrier end plate 13a.
  • the connecting plate 16 has two holes 17 which are circular in the present case in order to accommodate clamping wedge bolts, as will be explained later. However, these holes can also be punched slots for flat clamping wedges.
  • the connecting plate 16 opposite is welded to the underside of the U-profile piece 13, a mounting bracket 18, the distance from the connecting plate 16 increases slightly with increasing distance from the carrier end plate 13.
  • FIG. 3 shows the bending moment-resistant connection of two dome foot beams 10 and 10 'according to the invention.
  • the calotte foot beam 10 with its end having the U-profile piece 14 and the calotte foot beam 10 'with its end carrying the U-profile piece 13' and the connecting plate 16 'and the mounting bracket 18' are pushed together, the distance widening between the mounting bracket 18 'and the connecting plate 16' facilitate the advance of the lattice girder 10 up to the girder end plate 13a.
  • connection of the dome foot beams which can be made with very simple means, creates the bending stiffness required for the pre-threading in the required directions and also an exact alignment of the pre-attached dome foot beam with that already anchored in the dome.
  • connection is torsionally rigid.
