Mechanical anchors are also known as post-expanded bottom anchors or self-cutting bottom anchors. The working principle is safe and reliable, that is, through the mechanical lock key opening and the shear force generated by the anchor hole, the tensile force is provided to the connected object.
Features of mechanical anchors:
a. Compared with other general anchors, the diameter of the drilled hole is smaller, but it has stronger tensile, anti-fatigue, anti-seismic and other functions, and is safe and reliable.
b. According to different application environments, there are different materials and different anti-corrosion functions, which can meet the needs of customers.
c. The variety standard is complete, there are special products for special environments, and various special standard products can also be customized according to customer requirements.
d. It has a wide range of applications and is suitable for concrete substrates of various strengths and other substrates that can be cut.
e. Simple structure, excellent corrosion resistance and wear resistance, high temperature resistance, can be welded.
f. Applicable to all environments that are not suitable for chemical agents and planting glue.
Equipment clarification for mechanical anchors
A: Preset device
1. Use the impact drill and the special anchor drill bit to determine the drilling depth and the drilling diameter according to the requirements of the standard type of anchor.
2. Use a manual pump or a pneumatic pump to clean the hole, and the hole must be cleaned.     
3. Before installing the equipment, first tighten the various parts of the anchor bolt to ensure that the components are not loose, and then pierce the drilled holes.
4. Tap the anchor bolt to the bottom of the hole with an electric hammer sleeve and fully expand it, and use a torque wrench to tighten the anchor bolt nut.
5. Loosen the nut on the anchor bolt, prepare the fixed connection, and tighten the nut with a torque wrench.
The torque must be applied according to the standard type of the anchor bolt to be installed. After reaching a certain torque, the installation is completed.
B: Penetrating equipment:
1. Use the impact drill and the special anchor drill bit to determine the drilling depth and the drilling diameter according to the requirements of the standard type of anchor.
2. Use a manual pump or a pneumatic pump to clean the hole, and the hole must be cleaned.       
3. Place the anchor nuts and washers, and fasten all accessories. The bottom of the screw should be flush with the bottom of the cone.
4. Put the anchor bolt into the hole through the fixture, push the anchor bolt into the hole with an electric hammer sleeve and fully expand until the gasket and nut are against the surface of the substrate.
