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
