Introduction to Hengshui Kaixiang Anchors

The following types of anchor clamps were commonly used in the early days
(1) Clamp
． Conical clamps
There are two types of conical clamps: those for steel wires and those for steel bars. They can only clamp one steel wire or thick steel bar.
． Wedge clamp
There are wedge-shaped holes on the wedge clamp plate, which are available in single hole and double hole. The wedge is driven into the wedge-shaped hole, and the steel wire is clamped on the side of the wedge. A prestressed steel wire can be clamped on the side of each wedge.
． Wave clamp
The wave clamp is pressurized by a jack, and the wave clip clamps the steel wire, and can anchor multiple steel wires at one time.
． Upsetting clamp
The upsetting clamp performs tension and anchoring by upsetting the ends of steel bars. It can anchor multiple steel bars at one time.
(2) Anchors
． Screw end rod anchors
Screw end rod anchors have two forms: welded joints and heading joints, and are mainly used to anchor thick steel bars.
． Helping bar anchor
Helping bar anchorage is welded by a square steel lining plate and three supporting bars. It mainly anchors thick steel bars.
． Tapered Anchors
Steel tapered anchors, also known as French anchors, were first used by Freisinet in France and can anchor multiple high-strength steel wires.
． Concrete-in-steel screw anchor clamp
The concrete-in-steel screw anchor clamp mainly uses high-grade concrete or high-grade expanded cement poured into the steel pipe to anchor the steel wires, and then tensions them to anchor multiple high-strength steel wires. In the early prestressed concrete components, the applied prestressed tonnage was smaller than that of screw end rod anchors, and the stress loss was relatively large. Therefore, the permanent force of the prestressed force in the component was relatively small, compared with Compared with modern prestressed steel, the amount of steel is still relatively large, and it is not very convenient to use.
Although early prestressing has many imperfections, it still has many advantages compared with ordinary reinforced concrete: for example, prestressing can improve the crack resistance and stiffness of components, increase the durability of components, save steel and Concrete, reduce the weight of components, etc. This is where the vitality of prestressing lies.
