Full threaded steel self drilling rock bolt / Hollow anchor bar / Anchor rods
Anchor rod refers to the slender rod body that penetrates into the interior of rock and soil and controls the deformation of rock and soil, which can include backing plate, nut and other components. As a tensile member deep into the stratum, one end of the bolt is connected with the engineering structure, and the other end is deep into the stratum. The whole bolt is divided into free section and anchorage section. The free section refers to the tensile force at the bolt head is transmitted to the solid area of the anchor, and its function is to apply prestress to the bolt. The anchorage section refers to the area where the cement paste binds the prestressed bar to the soil layer. Its function is to increase the bonding friction between the anchor solid and the soil layer, increase the compressive effect of the anchor solid,
