Abstract
The utility model relates to a structure that can measure and control length error of steel wire of suspension bridge main cable strand. The utility model is characterized in that inner strand error control steel wires (3) and the existing standard wires (1) are out of the strand. Dived the length of each inner strand error control steel wire into many sectional lengths and mark each section with mark (4). Align the start ends of these inner strand error control steel wires before cable facture. During cable facture, measure the deviation amount of each inner strand error control steel wire taking the standard wire as the norm. The deviation amount is the single steel wire length accuracy error in the stand. Analyze the sectional value of inner strand error control steel wire according to measurement results. Adjust the back tension of steel wires during cable facture to control the length error of each steel wire in the stand according to structure analysis. This structure can control the length of suspension bridge main cable strand and the length error of each steel wire in the suspension ridge main cable strand.
Description
Technical field:
The utility model relates to a kind of structure of measuring and controlling internal steel wire length error of main cable bundle for suspension bridge, is mainly used in the error in length of measuring and control main rope of suspension bridge bundle thigh inner wire.Belong to the bridge construction technical field.
Background technology:
Before the utility model is made,, normally on the cross section is the corner angle of hexagonal main push-towing rope bundle thigh, a standard silk and mark silk are set in order to control the length of main rope of suspension bridge bundle thigh.This mark structure can only be used to control the length of main rope of suspension bridge bundle thigh, and can not control the error in length of individual wire in the main rope of suspension bridge bundle thigh.This can cause main rope of suspension bridge bundle thigh in use owing to burst discontinuity that interior each steel wire length differs and causes, and makes main push-towing rope bundle thigh can not reach projected life and load requirement.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of structure of measuring and controlling internal steel wire length error of main cable bundle for suspension bridge is provided.
The purpose of this utility model is achieved in that a kind of structure of measuring and controlling internal steel wire length error of main cable bundle for suspension bridge, it is characterized in that: make error control steel wire in one or more strand, be distributed in bundle burst neighboring together with original standard silk, error control steel wire length overall in the every thigh is divided into a plurality of section lengths, in every thigh, make a mark every a segmentation on the error control steel wire, before the system rope starting point of error control steel wire in one or more strand is alignd, in system rope process, with the standard silk is benchmark, measure error control steel wire and its bias in the every thigh respectively, be bundle burst interior individual wire length trueness error, fragmentation value according in the measurement result halved tie thigh strand of interior error control steel wire is analyzed, according to analysis result, by the adjustment of steel wire backward pull in the system rope process being controlled the length of bundle strand interior each steel wire.
This structure can be used to control the length of main rope of suspension bridge bundle thigh, can control the error in length of individual wire in the main rope of suspension bridge bundle thigh again.In use each steel wire is stressed evenly to guarantee main rope of suspension bridge bundle thigh, has guaranteed the safe operating life and the load requirement of main push-towing rope bundle thigh.
Description of drawings:
Fig. 1 is for adopting the main push-towing rope bundle thigh sectional schematic diagram of the utility model structure.
Error control steel wire deployed condition schematic diagram in the thigh that Fig. 2 is adopted for the utility model structure.
The specific embodiment:
Referring to Fig. 1, in order to measure and control internal steel wire length error of main cable bundle for suspension bridge, the utility model has been made error control steel wire 3 in 10 thighs, be distributed in bundle burst neighboring together with original standard silk 1 and mark silk 2, with the length precision of different parts steel wire in the detection beam thigh manufacturing process.
Referring to Fig. 2, error control steel wire length overall is divided into seven sections section lengths (having three among the figure) in strand, in every thigh, make a mark 4 every a segmentation on the error control steel wire, before the system rope starting point of error control steel wire in 10 thighs is alignd, in system rope process, with the standard silk is benchmark, measure error control steel wire and its bias in 10 thighs respectively, be bundle burst interior individual wire length trueness error, fragmentation value according in the measurement result halved tie thigh strand of interior error control steel wire is analyzed, according to analytical structure, by the adjustment of steel wire backward pull in the system rope process being controlled the error in length of bundle strand interior each steel wire.
