Description
Technical field
The present invention relates to a kind of prestressed anchor steel strand tension device.
Background technology
Parallel steel stranded wire guy system is using steel strand wires as carrying cable body, based on group anchor technology, utilizes group's grip
Tool bears by a kind of system of drag-line transferring structure sound load.Steel strand stay cable system be generally operational in 0.30Rb～
0.45Rb low stress area, the construction stage is only 0.1Rb sometimes, so anchor clamp anchoring efficiency is to ensure that guy of twisted steel cable is answered low
The key of normal work under power state.Parallel steel stranded wire suspension cable typically makes at the scene, installs, and in technique, steel strand wires are by root
Through anchorage, tensioning pretension, set up initial stress, then (also have single tensioning repeatedly to reach by integrated regulation to builder's tonnage
Builder's tonnage).During single pretension, in the past limiting plate was passed through using tensioning self-anchored method repeatedly, when putting, made intermediate plate with steel
Twisted wire retraction with so that from anchor.When this technique runs into long rope, work clip sheet unavoidably repeatedly clamp steel strand wires, on the one hand,
Intermediate plate and steel strand wires are subject to different degrees of damaging；On the other hand, drag-line steel strand surface coating for protection against corrosion and iron filings etc. come off heap
Amass in intermediate plate teeth space, affect anchoring effect.
Content of the invention
The invention aims to making up the defect of prior art, a kind of prestressed anchor steel strand tension is provided to fill
Put.
The present invention is achieved by the following technical solutions：
A kind of prestressed anchor steel strand tension device, including fixing end support, fixing anchorage, limited block, stretching end support,
Displaced block, displacement anchorage, hydraulic jack, push block it is characterised in that：Described fixing end support is provided with fixing anchorage, institute
The front end stating fixing anchorage is provided with limited block, and the side of described fixing end support is provided with stretching end support, described stretching end support
Centre be fixed with jacking bracket, described jacking bracket be respectively arranged on the left side and the right side displaced block, push block, described displacement
Block is fixedly connected by screw rod with push block, and described displaced block is fixed with displacement anchorage, and described jacking bracket is provided with liquid
Pressure jack, the side of the push rod of described jack is push block, and described fixing anchorage and displacement anchorage are by steel strand wires even
Connect, one end that described steel strand wires are located at displacement anchorage is provided with pulling force sensor, near displacement anchorage on described jacking bracket
Side be provided with laser ranging system.
A kind of described prestressed anchor steel strand tension device it is characterised in that：Described displacement end support is provided with
Hydraulic means, described hydraulic means is connected with described hydraulic jack.
A kind of described prestressed anchor steel strand tension device it is characterised in that：Also set on the support of described displacement end
There is controller, described controller is connected with pulling force sensor, laser ranging system, hydraulic means.
A kind of described prestressed anchor steel strand tension device it is characterised in that：Described fixing anchorage and displacement anchor
The centrage of the steel strand wires fixing hole of tool is on same straight line.
It is an advantage of the invention that：Assembly of the invention structure is simple, convenient disassembly, and the process of assembling can be by device removal
So that next time uses, also it is avoided that unnecessary waste.Different anchorages, steel strand wires and work surface size are had and is generally suitable for
Property.By the length of action of adjusting screw rod and sleeve, tensioning position can be adjusted and move in the horizontal direction, therefore have according to existing
Field situation adjusts the function being suitable for, and can carry out digitization monitoring by sensor and range unit.
