1/2 Threaded Rod Anchor
1/2 Threaded Rod Anchor are frequently utilized for offering strong support to roadways with substantial deformation in high-stress mines. those roadways can encompass full rocky roadways, coal roadways, and semi-coal roadways. moreover, those anchors also can be employed for making sure high-strength and lengthy-lasting aid to railroads, highways, hydropower initiatives, and different similar endeavors.
1/2 Threaded Rod Anchor is a unique rod used for strengthening and stabilizing underground engineering or civil engineering. it's far manufactured from excessive-electricity metallic and has a threaded floor with out longitudinal ribbing. the threaded anchor rod with out longitudinal rib adopts threaded connection approach, which may be effortlessly linked with other rods or structural parts to form a solid aid machine.The Threaded Anchor without Longitudinal Rib is a unique and high-strength steel rod specifically engineered to enhance the stability and fortification of underground and civil engineering projects. With its clean threaded surface and shortage of longitudinal ribbing, this anchor offers seamless integration and easy connection with different rods or structural elements,forming a dependable and secure support system. Its versatility and reliability make it an essential component for reinforcing various construction ventures.
Anchor Characteristics of 1/2 Threaded Rod Anchor:
1. superficially it restricts the rock and soil body from the original body.
2. Macroscopically it increases the cohesion of the rock and soil body.
3. anchor rods are not handiest used in mines, however extensively utilized in engineering era for active reinforcement of slopes, tunnels, dams and so on.
4. anchor is the fundamental element of tunnel support in modern underground mining, which binds the fringe rock of the tunnel together, so that the perimeter rock supports itself.
1/2 Threaded Rod Anchor can be extended in length through threaded connection to meet different engineering needs. This anchor rod has high tensile, shear and torsional strength, which can provide reliable support and fixation. It is widely used in tunnels, underground mines, water conservancy projects, transportation and other fields to strengthen rock, soil or concrete structures. The advantages of threaded anchors without longitudinal ribs include easy installation, light weight, reusability, and short construction period.
1/2 Threaded Rod Anchor can improve engineering construction efficiency, reduce engineering cost, and has a long service life. All in all, threaded anchor without longitudinal rib is an important engineering support material, which can provide strong and reliable support, and is widely used in various underground engineering and civil engineering.

Product Selection and Working Conditions of 1/2 Threaded Rod Anchor:
1. Product selection: support designers according to the roadway section of the surrounding rock geological conditions to detect the surrounding rock to pressure parameters, and then combined with practical experience, can choose different specifications of the anchor.
2. Using working conditions: Users have to have drilling and installation gadget, resin anchors and so on. so one can growth the effect of assist, after the set up of anchor rods, plus the installation of anchor net anchor cable and slurry. the drilling size and intensity ought to be used in step with the specifications of anchor rods and anchoring marketers; thinking about the energy conditions of the site, it is recommended to prioritize the use of pneumatic anchor drilling rigs or hydraulic anchor drilling rigs so that the drilling and installation are carried out in the same machine: for the use of high rock hardness site selection of the 7655 wind hammer drilling, pneumatic coal drilling and stirring installation. Stirring installation of rated output speed ≥ 400 rpm output torque, for the full-length anchoring should be 2 60Nm; for end anchoring should be 240Nm machine.
Advantages of 1/2 Threaded Rod Anchor
1. Anchor end and fastening end do not require machining.
2. Equal strength for the whole length, high material utilization.
3. big anchorage force.
4. pre-stressing hot piece is furnished, easy to control the set up exceptional.
5. rapid installation velocity.
6. It is made according to the rotating direction of the digging tool, so that the anchor will not exit during the operation.
