  • the invention relates to a device for the production and installation of tendons for bridge structures, which tendons consist of tension wires or tension strands and a sheath of interconnected tubular elements.
  • the invention further relates to a method for the production and installation of tendons for bridge structures, with tension wires or tension strands are introduced into interconnected pipe elements, the tension wires or tension strands and the pipe elements are transported to the site, corresponding to the construction site of the desired length of the tendon to be produced Number of pipe elements is connected to each other, a desired number of tension wires or tension strands are inserted into the interconnected pipe elements and the tension wires or tension strands are cut to the desired length.
  • bridge structures usually tendons are inserted in the individual sections and poured with concrete.
  • the individual bridge sections thus receive a corresponding bias, which causes no or very little concrete tensile stresses occur in concrete cross-section in external actions such as dead weight.
  • the bridge component is stiffer and has lower deformations, especially deflections, even at high loads.
  • Tendons are for example from the AT 404 474 B known.
  • a method for producing a band-shaped clamping element is, for example, from AT 004 021 U1 out.
  • the tendons are assembled in a factory by a corresponding number of tubular elements is connected together and a corresponding number of tension wires or tension strands are inserted into the interconnected tubular elements. Thereafter, the tendons thus produced are rolled up and transported to the construction site, where they are in turn unrolled and lifted by means of cranes or the like in the construction site sections to be produced. For relatively large sections are for producing the tendons accordingly large halls required.
  • the tendons are partially assembled only at the site.
  • the individual components such as pipe elements and tension wires or tension strands are transported to the site and assembled there at a suitable location. Thereafter, the produced tendon is lifted by means of cranes in the construction section to be produced.
  • the object of the present invention is to provide a device and a method mentioned above, whereby the manufacture and installation of the tendons can be simplified and accelerated. Disadvantages of known methods and devices should be avoided or at least reduced.
  • the object of the invention is achieved by an above-mentioned device, wherein on a frame rotatably arranged in both directions reel for receiving the tendons is provided.
  • the device according to the invention makes it possible to roll up a tensioning element assembled on the construction site and then to unroll it again with the aid of a crane or the like in the construction section of the bridge structure to be produced.
  • the device thus supports both the manufacturing and laying process by the rolling and subsequent targeted unrolling in the construction section to be produced.
  • the reel is removable from the frame of the device.
  • several reels for only one frame can be provided and worked with several reels simultaneously.
  • the removable embodiment can be realized according to a further feature of the invention by at least 3, preferably adjustable in the radial direction arms on which the reel is attachable.
  • the reel can be plugged without tools on the arms on the frame and then a non-rotatable Connection between the arms and the reel done by radial adjustment of the arms.
  • the adjustment can be done for example pneumatically or hydraulically.
  • the reel is preferably made of several interconnected parts.
  • the reel for transport can be easily disassembled and transported with small vehicles.
  • the fasteners should allow the fastest possible assembly and disassembly and can be formed for example by bolts that are secured with corresponding pins.
  • a drive for rotating the reel is provided.
  • the rolling up of the finished tendon on the reel but also the rolling can be supported accordingly.
  • the drive can be formed by an electric motor and possibly a corresponding gear.
  • the transmission can be realized for example by a gear transmission.
  • a control device is preferably connected to the drive.
  • Einhakvoriquesen are preferably arranged on the frame and or or on the reel.
  • the correspondingly designed hooking devices allow the arrangement of a hook of a crane and thus the lifting of the device of the frame and or or the reel.
  • the bottom of the frame is designed to accommodate the forks of a forklift. This allows the entire device to be easily transported by a lift truck.
  • the frame is designed to be dismantled.
  • the corresponding connecting elements are preferably designed so that a tool-free, simple and quick assembly and disassembly is possible.
  • the device can also be moved without the aid of a crane or a lift truck.
  • a movement of the device can also be done without towing vehicle.
  • the object of the invention is also achieved by a method mentioned above, wherein the produced tendon is wound on a reel rotatably mounted on a frame in both directions and then the tensioning member is unwound at the desired location of the bridge support member of the mounted on a crane or the like reel , As already mentioned above, this can simplify the manufacturing and laying process.
  • an anchor is attached to at least one end of the tendon before the produced tendon is wound onto the reel.
  • the corresponding anchors are already mounted on both sides of the tendon, so they do not have to be subsequently attached in the corresponding construction section.
  • the reel When the reel is driven by a drive, preferably electrically, the winding and unwinding of the tendon on or from the reel can be facilitated.
  • the reel is releasably connected to the frame.
  • the manufacturing and laying process can be further simplified.
  • the winding can be accelerated and simplified.
  • Fig. 1a to 1d illustrate the process steps in the manufacture and laying of tendons for bridge structures.
  • Fig. 1a shows a bridge of three construction sections A 1 , A 2 , A 3 existing bridge structure.
  • the construction sections between two bridge girders are produced one behind the other.
  • tendons are arranged for biasing the bridge structure in the individual construction sections and cast around by concrete.
  • the tendons are usually arranged overlapping in the construction sections A 1 , A 2 , A 3 . Accordingly, one needs for the production of a tendon a length which is greater than the length of a construction section A i . Since there are rarely such large halls for the production of tendons, the tendons are preferably made at the site of the site.
  • FIG. 1b illustrates the production of a tendon 2, wherein tube elements 4 are connected to each other and tension wires 3 or tension strands are inserted into the interconnected tube elements 4.
  • the tubular elements 4 consist for example of metal or plastic and usually have a length of 6 to 10 meters. About appropriate sleeves, the pipe elements 4 are connected to each other and possibly sealed with the help of adhesive tapes or the like. After the arrangement of a desired number of tension wires 3 or tension strands in the interconnected tubular elements 4 2 corresponding anchor body (not shown) are attached to the ends of the tendon. The thus produced tendon 2 is placed in the corresponding construction section A i . To manipulate the necessary cranes or the like, a correspondingly large space is required.
  • Fig. 1c illustrates a device 1 according to the invention for the production and installation of tendons 2, with a frame 6 on which a rotatably arranged in both directions reel 5 is arranged for receiving the tendons 2.
  • the device 1 thus serves to wind the assembled tensioning member 2, whereby the laying of the tendon 2 can be simplified. It can also be provided several reels 5 for arranging a plurality of tendons 2, so that all required for a construction section A i tendons can be prefabricated and wound up and then laid one behind the other.
  • Fig. 1d illustrates the laying process, wherein the reel 5 or the frame 6 of the device 1 is lifted by a crane or the like and is moved along the building section to be manufactured A i , so that the tendon 2 in the construction section A i can be inserted.
  • the space required for the assembly of the tendons 2 can be reduced and the insertion of the tendons 2 are simplified in the bridge sections.
  • Fig. 2 shows a view of an embodiment of a device 1 for the production and installation of tendons 2, comprising a rotatably mounted on a frame 6 in both directions reel. 5
  • the reel 5 is based on the 3 and 4 explained in more detail.
  • the reel 5 consists of several interconnected parts 7.
  • the parts 7 of the reel 5 are interconnected by appropriate fasteners, such as bolts or screws.
  • this is preferably constructed grid-shaped.
