Chemical anchors are able to form a strong bond between the screw and the base material through the bonding action of the chemical adhesive, providing high anchorage strength. It is capable of withstanding large loads, whether in tension, shear or pressure. It can be used in building structure reinforcement, heavy equipment fixing and other occasions that require high anchorage strength.
It will not produce expansion stress on the base material during installation as expansion bolts do, and is suitable for brittle materials such as concrete, bricks and so on. This avoids cracking or breaking of brittle materials and is also suitable for fixing of close margins and narrow members.
Application of chemical anchors
Building reinforcement: it can be used for structural reinforcement of old buildings to enhance the bearing capacity of walls, columns and other parts.
Steel structure fixing: it can firmly fix the steel structure members on concrete foundation or other structures.
Bridge engineering: it can be used for connection and reinforcement of bridge components.
Tunnel engineering: it can fix the pipelines, equipments and supporting structures in the tunnel.
Rail transportation: it plays an anchoring role in track laying and related facilities installation.
