Comparing the characteristics of the four kinds of mechanical anchor bolts, the organic chemical anchor bolt is also called adhesive type anchor bolt, which is composed of metal material extruder screw steel bar anchor glue. The component organic chemical pipe RM is composed of vinyl resin dry setting agent rapidly setting, with small edge spacing high bearing capacity.

According to the anchoring effect of the steel bar anchoring glue, the anchor bolt is the most widely used main keel fixed commodity at this stage. The embedded mechanical anchor bolt, to put it bluntly, is set in the structure in advance coagulates together with the precast concrete, thus producing an integrated anchor bolt. Because of the advantages of seamless splicing connection of embedded mechanical anchor bolt, it is considered to be one of the most reliable safest anchors.

The reinforcement anchoring force of the reamed anchor bolt comes the mechanical clamping force generated by the reaming at the bottom of the anchor hole the lock key in the middle of the anchor bolt expansion piece. The anchor bolt is divided into pre reaming anchor bolt self expanding hole anchor bolt according to the anchor bolt anchoring effect produced by the lock key in the middle of the expanding part of the anchor bolt the bottom of the anchor hole. Its bearing capacity Lashin bearing capacity are stronger than the three aspects of gender. The expansion type anchor bolt is a kind of anchor bolt which uses the expansion part to extrude the anchor hole edge to produce the anchoring effect of reinforcement. It is divided into torque operated expansion anchor bolt offset operated expansion anchor bolt. The reinforcement anchoring force of expansion anchor bolt comes the sliding friction between the expansion part the anchor hole edge, the relativity is weak in the bearing capacity tensile bearing capacity. Compared with the four kinds of anchors mentioned above, the organic chemical anchor bolt is more economic development, its application is more common; the embedded part anchor bolt the expanding hole anchor bolt are more safe, reliable excellent; the expansion type anchor bolt is recommended to be used in the construction of building curtain wall.
