Definitions

  • bracing in a fixing and / or Guide area are arranged essentially next to each other and that Provide the longer stays in each case at a greater distance from the side wall of the supporting body of the bridge than the adjacent one shorter guying is achieved that a high number of guying in Essentially the same level or with essentially the same course can be performed, the optimal for structural reasons or a represents at least advantageous course. If necessary, several can Layers of guy lines arranged in this way are provided, which are arranged one above the other at least in the fixing and / or holding area.
  • the block-shaped pilaster strips are formed as prefabricated prefabricated parts, with anchors equal to these finished parts or anchor connections for connection to the supporting body of the bridge can be.
  • the main advantage of prefabricated prefabricated parts is that that these have their full strength already when they are attached and because of the factory production are immediately available.
  • the pilaster strips can be bridged at those that reject the respective support Ends of the bridge sections or even within the length of each Bridge section, e.g. B. in the middle.
  • the prefabricated pilots can also be used with other concrete bridges if e.g. B.
  • a bridge is produced in the cycle shift process, wherein, preferably in Abutment area, a relatively large section of bridges by factory manufactured, pushed out with the help of presses and after manufacture of the next one larger section is pushed with this.
  • the pilaster strips External tensioning cable attached in sections is used to hold the device.
  • Pilasters can be used to hold guy lines.
  • each bridge section Mounted pilaster strips 11, the inside 12 of which is a guide and in the area of a Paragraph 12a of FIG. 4, an additional deflection for each to the next Form section guided guying.
  • the pilaster strips for lower guying were designated by 13 in FIG. 6.
  • the two are initially the same Bridge sections 2, 2a erected in a corresponding formwork, the Embodiment at the ends of the bridge sections 2, 2a, the pilaster strips 11 attached and connected by spanned guy lines 14.
  • the pilaster strips can also be varied within the length of the bridge sections be provided.
  • the Sections 3, 3a lined up and with each other through the fixing and / or Guide area 9 guided guy lines 15 connected to the pilaster strips 11 of sections 2, 2a are diverted to their pilaster strips.
  • the top Guyings 16 of sections 4, 4a are on the pilaster strips 11 of sections 3, 3a redirected and so on, so that finally in the area of the support from FIG.
  • FIG. 5 and 7 show that for the same section there are also two superimposed ones Guyings, e.g. B. 15 can be performed, which then in one another arranged brackets of the pilaster strips 11 on the corresponding section recording Find. Also several guyings arranged one above the other at the same time Section are possible with both lens types.
  • lower bracing 18, 19, 20 are attached, which here from the Starting from the middle of the field, connect the opposite bridge sections, the Guyings 18, analogous to guyings 14 in FIG. 3, guyings 19 seen from the center of the field analogous to the guy lines 15 above the support and Finally, the guy lines 20 are ranked analogously to the guy lines 16, 17 are so that the guy image in the section of FIG Anchoring image according to Fig. 3 is similar. Can between the support and the center of the field also some sections of both upper stays 17 and lower Guy 19 or 20 can be reached.
  • the pilaster strips 11, 13 are preferably prefabricated in the factory and can therefore, since they have their full strength, those that occur immediately after installation Anchoring forces are transmitted.
