Description
Technical field
The present invention relates to a kind of reaction frame for steel wire rope prestressed anchor cable stretching.
Background technology
The tension process of steel wire rope prestress anchorage cable reaction frame steel wire rope prestress anchorage cable suitable for cable way bridge engineering, it is existing
Mainly it is made up of steel wire rope prestress anchorage cable tension tool jack, crossbeam, steel backing plate, such a tension tool exists following
Shortcoming：
1st, the accuracy of actual elongation is poor
Existing steel wire rope prestress anchorage cable tension tool exists because two synchronous jacks can not be synchronous in stretching process
And run-off the straight phenomenon, cause the actual prestressing force of steel wire rope not reach design requirement, and the accuracy of actual elongation is poor.
2nd, tensioning security risk is big
Existing steel wire rope prestress anchorage cable tension tool is in stretching process, and jack is directly by prestress application in activity
On crossbeam, the position of jack is adjusted by placing steel backing plate in very heavy top/bottom part, steel backing plate is single uneven distribution
Individual, globality poor in stretching process, produces shearing stress between steel backing plate due to applying prestressing force, causes steel pad
Plate may be extruded at any time, and tensioning security risk is high.
3rd, tensioning is less efficient
Existing steel wire rope prestress anchorage cable tension tool must be adjusted before each tensioning by manually installed steel backing plate
The position of hydraulic jack, and the angle of adjustment prestressed anchor cable stretching that must be repeatedly, add the labor intensity of workman,
Pulling rate degree is slow, and tensioning efficiency is low.
4th, stretching process stream line axially loaded can not be ensured
Existing steel wire rope prestress anchorage cable tension tool is simple in construction, and jack is placed on resistance face by steel backing plate,
In stretching process steel backing plate install be affected by human factors it is larger, both sides install can not concordantly not ensure steel wire rope prestressed anchor
Rope axially loaded in stretching process.
