Thread bar anchor bolt (prestressed bolt) : Thread bar bolt is composed of screw thread steel bar , high strength plate , casting damping nut , yield tube, washer , and other accessories . According to the structure of steel bar , the bolt has two stypes : rib rebar bolt and non-rib rebar bolt . The bolt is usually used in thick coal seam , that has high stress, large deformation, difficult to support and other poor environment . Feature : (1) the bolts have high strength stress , good support capacity can prevent the roof from sinking down , and the strata sliding . (2) fast and easy installation by mechanized tools. (3) be used with resin anchoring cartridge for permanent support . (4) be used in high stressed , large deformed area . (5) low price, widely used in coal mines, railways, hydropower and other types of roadway projects. (6)thread profile has higher strength than rod and offers excellent mixing capabilities in resins installation Pallet.
Tightlok threadbar bolt is composed of hot rolled ribbed bar, high strength plate , damping nut , yield tube, washer , and other accessories. Usually used in thick coal seams with very high stress and large Deformation. Features: (1) High tensile strength and good support capacity which can prevent the roof from sinking and sliding. (2) Fast and easy installation by mechanized tools. (3) Used together with resin cartridge for permanent support. (4) Sharp end device makes installation easier and faster. (5) Left hand thread direction available. (6) Specially "sandwich"device can buffer and release the pressure.
Full thread bar bolt is used together with dome plate and net for reliable ground support in mines, tunnels, slopes, or wherever. Feature: (1). The bar has closely defined mechanical properties which provide consistent performance under long term anchor loading. (2). In the longitudinal direcition , rock body has equal tensile strength , that is about 40% higher than the reverse-twist bolt in the same specification. (3). Extend the support area , not only be used by end anchoring , but also be used by fully anchoring , that has a better Support efficiency. (4). Low price, widely used in coal mines, railways, hydropower and other types of roadway projects. (5). Thread profile offers excellent mixing capabilities in resins installation. (6). The high ductility and smooth, relatively flat rate of strain hardening ensures a high margin of safety against tensile/shear overload in the case of transverse movements in the rock soil. (7). Can be cut and spliced at any point along its length. It is based on the request of each client.
