Definitions

  • the present invention relates to a method for producing a load-bearing structure, in particular a bridge, wherein sections of the structure are concreted in at least one formwork which is anchored to at least one existing load-bearing part of the structure itself.
  • FIG. 1 A known method of this type is shown schematically in FIG. 1.
  • C-shaped beams 3 are constructed to be movable symmetrically on both sides on a track and secured by means of tie rods 5.
  • These beams 3 encompass the formwork space at the front, in which a section 4 of the bridge can be concreted in a formwork, not shown, which is supported on the lower leg of the beam 3. If the sections 4 are frozen, the track can ver on them lengthened and the Träoer 3 are advanced by a section length, whereupon the next section can be concreted. If the beams 3 are not to be made prohibitively large and strong, only very short sections 4, for example 3 m long, can be concreted, as shown in FIG. 2 of the drawing, and the construction progress is correspondingly slow.
  • the pillar 2 must be designed with a widened head 1.
  • the present invention has for its object to provide a construction method and a device by means of which a gradual construction progress by much larger section lengths is possible with simple execution and complete reusability of the carrier material.
  • the solution to this problem is specified in the claims and in the subsequent description.
  • Figure 3 shows the procedure according to the invention.
  • a truss 6 made of prefabricated standardized elements is created symmetrically on both sides and anchored in the middle of the support 2 by means of tension members 7.
  • a track 8 is built onto the carrier 6.
  • a mobile beam 9 with rollers 10 is built thereon, which extends across the carrier 6 and consists of similar or the same prefabricated elements as the carrier 6.
  • the carrier 6 consists of two Strands, on each of which a rail 8 of the track is attached.
  • a formwork beam 12 which is also constructed from the same or similar elements as the beam 6 and the beam 9 and on which the formwork (not shown) for casting the bridge profile is located, is suspended by means of tie rods 11.
  • a C-shaped support 14 for a work platform 15 is mounted in the middle of the beam 9, which support 14 is also made of prefabricated elements similar to or identical to those of the trusses 6, 9 and 12 exists.
  • FIG. 3 shows the stage in which the first adjoining sections of the bridge profile 13 are concreted on both sides of the support 2. After concreting, the formwork must remain in place until the concrete has set sufficiently. During this time, as indicated in broken lines in FIG. 3, the beam 6 is extended further on both sides, and the track 8 is also lengthened on this beam, namely by the length of the following section 4 of the bridge. If the concrete is now set in the already concreted inner sections, it is switched off, the beams 9 with the formwork beams 12 are moved symmetrically outwards on the track 8 and secured. Now the formwork is prepared for the second sections and then the concrete is poured. With the beam 9, of course, the working platform 15 has also been moved forward, and it can be continued to be built on the carrier 6, in order to then advance another step and to concrete the next section 4.
  • FIG. 4 shows how, after a certain construction progress, the girder 6 is anchored to a section 4 located further outside by means of tension members 7, while the front; effective tension members and the inner parts of the carrier 6 can be removed.
  • the material released in this process is continuously used to extend the carrier 6 to the outside Ends needed.
  • These processes are indicated in FIG. 4 with dash-dotted lines.
  • the formwork beam 12 the beam 9 and the beam 6 can be dismantled and the material released can be used again with a different span of the bridge.
  • FIGS. 9 to 11 Before further details of the construction of the devices are dealt with, the embodiment variant which is shown schematically in FIGS. 9 to 11 will be discussed. Corresponding parts are identified in the same way as in FIGS. 3 to 6.
  • the support 6 is only shown on one side with a work platform in FIGS. 9 and 11, in practice it is normally worked symmetrically on both ends of the support at the same time in order to load the support 2 practically symmetrically to achieve.
  • the carrier 14 carrying the work platform 15 is arranged to be movable on the track 6 of the carrier 6 by means of rollers 20, but is of course secured in every working position. It is provided with a counterweight 21.
  • FIG. 9 shows the particular advantage associated with the design shown that a crane 22 can be mounted as soon as the carrier 6 and its track 8, not shown in Figure 9, have the required length.
  • the mobile working platform 14, 15 allows the construction of the support 6 to be of any length because the support 14 can also be moved forward continuously on the track of the support 6 that is being created.
  • the construction progress of the girder is therefore not restricted to the length of the working platform 15 during the concreting and setting of a section.
  • the beam 9 is put on according to FIG. 11 and the formwork beam 12 is attached. It can now be concreted in sections in the manner described above, while the carrier 6 is continuously extended by means of the work platform 15. As FIG. 11 and FIG. 10 show the completed bridge, long sections 4 can also be created by means of suitably long formworks, thanks to the arbitrarily long pulling of the support 6 between successive concreting work.
  • the crane 22 follows the construction progress. As indicated by thick and thin lines in FIG. 11, the carrier 6 can be weakened by partially removing elements within the effective anchoring 23, where it no longer has to absorb bending moments but only has to carry the crane. being the winner. Elements at the front end of the carrier 6 can be used.
  • Figures 7 and 8 show, for example, the structure of the load-bearing framework from standardized elements.
  • gusset plates 30 In the nodes of the trusses there are gusset plates 30 with which U-profiles 31 and 32 can be screwed to form the belt and diagonal bars and reinforcing flat profiles 33.
  • the screw connection is not shown for the sake of simplicity.
  • optimal combinations of standardized elements can be provided at each point to form the bars of the belt and diagonal bars of the framework.
  • additional reinforcing bars 34 made of flat iron can be provided in addition to the node sheets 30, in particular for transmitting the tensile and compressive forces from one bar of the belts to the other.
  • Certain nodes and / or bars of the framework can be dimensioned weaker than shown in FIGS. 7 and 8, it also being possible to provide only one gusset plate 30 to which elements 31 to 34 are screwed. On the other hand, a stronger design is also possible.
  • FIG. 6 shows the design of the anchors with the tension rods 7, which are anchored to a profile 35 inserted through the openings of the bridge profile. Their upper ends are in turn connected to profiles 35a, which hold the truss 6 down. Anchors 6 are also connected to the bridge profile for laterally securing the formwork beam 12.
  • FIG. 12 shows the arrangement of the rollers 20 on the beam 9 and the rails 8 on the supports 3.
  • a mounting plate 40 is screwed to the belt profiles 31 of the beam 9, with which the lateral holding profiles 41 for the rollers 10 are welded.
  • the rails 8 are screwed to the profiles 39, and the profiles 39 are supported on rods of the upper straps of the carrier 6 and screwed at at least one point according to FIG.
  • Between nodes are counter plates 43 from below against the bars of the upper straps and are provided with holes for receiving the fastening screws for the profile 39.
  • the gusset plates 30 plates 44 are screwed; which are welded to the horizontal struts 45.
  • FIGS. 14 and 15 show the anchoring of the supports 6.
  • the tie rods 7 are threaded at the top and can be tensioned by means of a nut 47 supported on a profile 46 by means of an axial ball bearing 48.
  • the profile 46 is supported on the hold-down profile 35a, with which plates 49 with welded-on hold-down tabs 50 are screwed on.
  • the hold-down tabs lie on gusset plates 30 of the lower chords of the girder 6 and thus hold down the relevant position of the girder on the wood 38 or on the bridge profile.
  • a support plate 51 is inserted, which is screwed to the lower belt profiles 31.
  • a plate 44 with horizontal strut 45 is also screwed to this node.
  • Figure 16 finally shows the suspension of the support rods 11 for the formwork beam 12.
  • the upper ends of the rods are threaded and can be tensioned or adjusted vertically by means of nuts 52, which are supported via axial ball bearings 53 on a cross profile 54, which on the Upper chord of the truss of the beam 9 rests.
  • Figure 16 also shows the side Ver striving of the individual trusses of the beam 9 by means of horizontal struts 45 and their mounting plates 44th
  • the counterweight 21 can be omitted and thus the load on the carrier 6 can be reduced if a track 8 made of C-profiles or I-profiles is provided, in which the rollers 20 engage laterally in a vertically secured manner.
