Description of Anchorage

Anchorage is a permanent anchoring device used in prestressed concrete and is an important 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.

Technical parameter of Strand Post Tension Round Flat Anchor

Main Classification of Bridge Anchorage

1: Tension end anchor: An anchor installed at the end of the strand that can be tensioned, also known as a prestressed anchor (round anchor, flat anchor).

(1) Round anchor: has good anchoring performance and self-anchoring performance

The round anchor has a good market and is disposable, and the general tension adopts a hollow jack;

(2) Flat anchors: Flat anchors are mainly used for lateral prestressing of bridge decks.

Hollow slabs and low-height box girders make the stress distribution more uniform and reasonable, which further refines the structure.

2: Fixed-end anchor: Installed at the other end of the stranded wire, usually buried in concrete, and does not require a pull-end anchor (P anchor). P-type anchors are also called squeeze anchors.

Application fields of Strand Post Tension Round Flat Anchor
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.

General Anchorage Construction and Installation Method
The general anchorage construction and installation method are to put a small number of explosives at the bottom of the hole, expand it into a spherical shape after several anchorage constructions and installations, and finally put the explosives into the anchorage construction and installation. Compared with the hole anchorage construction and installation method, this method has the advantages of good anchorage construction and installation effect, high work efficiency, fast progress, and low consumption of explosives. This method is often used in the construction and installation of short pile anchors for shallow foundations.

Warm tips About Anchorage
1. The anchors should be kept properly, and there should be no rust, water, and other sundries in use.
2. Apply lubricant on the outer surface of the tool clip and the inner surface of the taper hole of the anchor plate before use, and often remove the debris on the surface of the clip.
3. Safety measures should be taken during tensioning, and no one can stand after the tensioning jack.
4. The anchor system should be used together and cannot be mixed with other systems.
