Anchorage Device Anchorage Coupler Round Anchorage Mutiple Holes
Description of Strand Post Tension Round Flat Anchor
Anchorage is a permanent anchoring device used in prestressed concrete and is an integral part of applying the shrinkage force generated by the prestressed tendons to the construction. In post-tensioned structures or components, in order to maintain the tension of the prestressed tendons and transmit them to the inside of the concrete, the anchoring tool can improve the bearing capacity of the bridge, increase the span of the bridge, and reduce the weight of the bridge.

Main Classification of Bridge Anchorage
Construction and installation of complex anchors
1. The construction and installation of complex anchorages are also called "directional anchorage construction and installation". Through certain technical measures, the explosion energy and explosion scale are strictly controlled, so that the sound, vibration, damage area of the anchorage construction and installation, and the slump range of broken objects, are controlled within specified limits. In cities and factories, complex old bridge buildings or structures are often required, such as buildings, workshops, chimneys, water towers, and various foundations, which are often constructed and installed with complex anchors.
2. There are many factors to be considered in the construction and installation of complex anchorages, including the geometry and material of the anchorage construction and installation body, the explosives used, the amount of charge, the simple construction layout and charging method, the covering and protective measures and the surrounding environment, etc. Among them, the most important is The number of explosives and charges.
Application Fields of Prestressed Tension Round Anchorage
Highway bridges, railway bridges, urban interchanges, urban light rails, high-rise buildings, water conservancy and hydropower dams, port terminals, rock mass slope protection anchoring, foundation reinforcement, tunnel mine roof anchor roof, prestressed grid, subway, large buildings, halls, Warehouse workshop, tower building, heavy lifting, sliding film intermittent propulsion, bridge, and tunnel jacking, large containers and ships, sleepers, replacement of bridge supports, bridge and building reinforcement, steel reinforcement works, anti-magnetic and anti-corrosion works (fiber anchors) ), carbon fiber reinforcement, pre-tensioned beam field construction, external prestressing engineering, stay cables, suspension cables, etc.
Notices of Prestressed Tension Round Anchorage
(1) For the cutting of prestressed ribs, a grinding wheel saw should be used, and arc cutting should not be used;
(2) When the steel strands are bundled, they should be straightened out one by one, bundled into bundles, and must not be disordered. The extruded anchorage or embossed anchorage at the fixed end of the steel strand shall be assembled with the bearing plate and spiral reinforcement in advance;
(3) The equipment and instruments used for prestressing shall be regularly maintained and calibrated;
(4) Before the prestressed tendons are tensioned, the concrete strength and compression test report shall be provided. When the compressive strength of concrete meets the design requirements and is not lower than 75% of the design strength grade, prestressing can be applied;
(5) Before the prestressing tendons are tensioned, the surface of the bearing plate should be cleaned and the quality of the concrete behind the bearing plate should be checked. If there is a cavity in the concrete, it should be repaired with epoxy mortar before tensioning;
(6) When the anchor is installed, the anchor plate should be straight, the clip should be tightened, and the position of the clip should be uniform: but the clip should not be beaten too hard when tightening the clip, so as not to damage the clip.
