As the core material of prestressed system, epoxy coating steel strand is widely used to ensure the safety of building structure and prolong service life. However, in prestressed engineering, anchor withdrawal usually involves removing or recovering the anchoring components at the end of steel strand for inspection, maintenance or replacement. The traditional method usually uses anchor withdrawal device and front card type jack to cooperate construction, anchor withdrawal device is generally suitable for ordinary round steel strand, although ordinary anchor withdrawal device can remove anchoring components, but there are still the following shortcomings: 1) low efficiency: long time-consuming and difficult construction, especially in large-scale engineering. 2) Safety risk: traditional anchor withdrawal device may cause safety hazards to construction personnel in some cases, and there is a risk of difficulty in withdrawing anchoring components or even unable to take out anchoring components in epoxy steel strand. Therefore, how to effectively and safely take out anchoring components is a problem to be solved in the current epoxy coating steel strand anchor withdrawal operation. SUMMARY

[0003] The utility model aims at solving the deficiency in prior art, provides a portal anchor withdrawal device for epoxy coating steel strand, which can quickly release the tensioned epoxy coating steel strand, improve the anchor withdrawal speed of steel strand and greatly improve the safety, and further promote the application of prestressed construction.

[0004] To achieve the above-mentioned purpose, the technical scheme provided by the utility model is as follows: a portal anchor withdrawal device for epoxy coating steel strand, comprising a workbench, a supporting leg and a stiffening rib; a threading slot is formed on the workbench for threading through the epoxy coating steel strand, the supporting leg is vertically arranged at the two ends of the workbench respectively, each supporting leg is equipped with a stiffening rib, the stiffening rib is connected with the supporting leg and arranged at the bottom of the workbench, and a working space for placing the epoxy coating steel strand to be withdrawn is formed between the workbench, the supporting leg and the stiffening rib.

[0005] Further, the workbench comprises a supporting plate, and the supporting plate is spaced apart at a preset distance.

[0006] Further, the preset distance is 2cm.

[0007] Further, the supporting plate is a Q235 steel plate.

[0008] Further, the tensioner is arranged on the top of the workbench and can be connected with the epoxy coated steel strand passing through the threading slot.

[0009] Further, the tensioner is connected with a hydraulic device.

[0010] Further, the length of the leg is greater than the length of the stiffening rib.

[0011] Further, the leg is a Q235 steel leg.

[0012] Further, the stiffening rib is a Q235 steel stiffening rib.

[0013] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0014] By using the utility model, the anchor withdrawal construction is simple and easy to operate, the construction efficiency is high, the safety accidents can be effectively prevented, the utility model is suitable for various construction environments, the cost is low, the utility model is easy to manufacture, and the construction cost can be effectively reduced.
