Anchor Barrel and Wedges | Prestressed Cable Bolt Grips Factory | ZF Mining

Barrel and Wedge

Prestressing anchorage can be selected from a wide range of steel wire root number range from 1 to 55; compact structure, anchoring efficiency coefficient is higher than 0.95; anchoring performance is stable, reliable, with good performance of the release of tension self-anchor construction operation is simple; ring anchor has strict corporate standards anchor mouth prestress loss of not more than 5% of the strand does not have any damage to the production of the vario-angle block precision hole wall is smooth; clamping the design and the anchor hole Match the design of the clip and the anchor hole so that in the tensioning time can be in a unified follow up the force uniformly.

Anchor barrels and wedges (also known as anchor grips) are essential components in the prestressed cable bolting system. They are designed to secure the end of the cable bolt, maintaining the tension required to stabilize massive rock strata in underground coal mines and tunneling projects.

Prestressing anchorage can be basically divided into: anchor ring, clip and anchor plate, can also be divided into: anchor ring, clip and anchor plate and spiral tendons several parts.

1. CLIP

Prestressing anchorage clip is the key part of the anchorage, in appearance is divided into work clip and tool clip, in the process of use can be reapplied, is made of alloy steel. Prestressing anchorage manufacturer's anchorage can be used in the work clip, also can be used in the construction of round anchorage above, also can be used in the box girder construction of flat anchorage, porous connectors are also commonly used.

2. Anchor ring

 

anchor ring is also a key component of the anchorage, round anchorage using carbon steel, flat anchorage using 40Cr steel manufacturing.

3. Anchor plate

Anchor plate of prestressing anchorage is the key part of the anchor ring load transfer to the concrete under the anchor, using a total transfer mode implementation, how the stress distribution under the anchor affects the cracking of the concrete under the anchor, the size of the load-bearing capacity, so it is extremely important.

4. spiral tendon parts

can be used as distribution tendons in the construction of concrete under the anchor, which can be used to prevent the occurrence of concrete cracking phenomenon in the construction, and then the spiral tendon curing function has been strengthened. Prestressing anchorage manufacturers in the construction of the bellows is also an important part of the construction, but its role is relatively small, just in the concrete curing to play an auxiliary role.
