A bolt anchor is a type of fastener consisting of a head and a screw (a cylinder with an external thread). It needs to be used with a nut to fasten and connect two parts with through holes. An anchoring component that is anchored to a hardened concrete substrate.

Anchor bolts are divided into the following four categories according to their working principle and structure.

1.  Inflatable anchor bolt (abbreviated as expansion anchor bolt) The expansion anchor bolt uses the relative displacement of the expansion cone and the sleeve to promote the expansion of the sleeve, and the expansion and extrusion force with the concrete hole wall, and the pull-out force is generated by shear friction. To achieve anchoring of the fixture. The expansion anchors are divided into different types according to the expansion mode of the sleeve: torque control type; displacement control type.

2.  Reaming type anchor Bolting type anchoring bolt is the reaming of the concrete at the bottom of the borehole. The mechanical interlocking between the concrete slope formed by the reaming and the anchor expansion cone is used to realize the anchoring of the structural fixing member. The anchoring force of the reaming type anchor is mainly caused by the direct pressure between the expansion cone and the concrete cone hole, and not only the indirect expansion friction force, therefore, the expansion extrusion force is small.

3.  Bonded anchor bolts are made of special chemical adhesives (anchor glue), which are used to cement the screw and the internal threaded pipe in the bore of the concrete substrate, through the adhesive and the anchor and bond. The bonding and locking function between the agent and the concrete hole wall realizes anchoring to the fixing member.

4.  Chemical planting chemical barging is to fix the ribbed steel bar in the concrete substrate through the chemical binder (anchoring glue), and realize the anchoring of the ribbed steel bar by bonding and locking.
