Self Tħaffir Rock Bolt Sħiħ Ħajt Bar Vojt Ankra Bar Ankra Vireg

Hollow anchor, the anchor body adopts hollow design, the hole in the body serves as a channel for drilling high-pressure and water and grouting channel, compared with the solid body, the hollow body design can achieve achieve better stiffness and shear strength. The outer surface of the anchor body is full-length standard large-pitch threaded structure, the threaded structure the threaded structure is convenient for cutting and lengthening of the anchor, and comcomped with the smooth body, it increases the bonding area between the anchor body and the grouting material and improves the anchoring force.

Hollow anchor rod rod tensile strength reached more than 300MPa; torque greater than 40N-m, its strong tensile, light weight; and can be cut, not easy to damage the cutter, the surface of the anti-static, flame retardant, cutting not produce sparks, corrosion resistance, heat insulation insulation, long-lasting durability. The following engineering experts from the anchor business of Zhongfu Mining Support Factory will summarize some of the advantages of hollow anchors in the anchoring environment for you

Hollow anchor bars come in two primary thread types: R thread and T thread. The R thread conforms to the ISO10208 standard, offering reliable performance in standard applications. However, the T thread, with its deeper teeth, provides even greater support force and is particular advantageous in applications where high frictional resistance is required. L-adeżiv frizzjoni forza ta ' T ħajt bars huwa tipikament doppju dak ta' R ħajt bars ta ' l-istess dijametru , tagħmel minnhom il - preferut għażla għal awto-tħaffir ankra boltijiet, speċjalment in mikropile applikazzjonijiet.

Meta veloċità u effiċjenza huma paramount, hollow anchor bars offer a distinct advantage. The self-drilling capability of these bars eliminates the need for separate drilling and grouting stages, significantly reducing installation time. In contrast, the grouting process associated with threaded bars can be more time-consuming, although it provides a high level of stability.
