Low-retracting prestressed strand anchor and connector combination
The invention discloses a low-retracting prestressed strand anchor and connector combination, comprising an upper strand anchoring end ancho unit and a lower strand anchoring end anchor unit. The upper strand anchoring end anchor unit comprises a strand guide disposed within a first tube, an anchoring end clip anchor and a compression spring. The lower strand anchoring end anchor unit comprises a tension end clip anchor disposed in a second tube; the bottom end of the second tube is provided with a back-filling regulator. A connector is provided between the two anchor units; two ends of the compression spring are in tight contact with the ends of the anchoring end clip anchor and of the connector. By the use of the combination in the prestress assembly of modular units, retracting prestress loss is low; the combination is suitable for connection of frame columns of steel structure module building units and is reasonable in structural design and reliable to connect; after steel strands are tensioned and anchored with the combination, the upper and lower modular unit frame columns are prestressed into a whole, thus resisting upsetting moment pull generated by lateral wind load or seismic action.
