Expansion Anchor

An expansion anchor is an anchoring device used to secure objects or structures. It usually consists of a metal tube and an expansion body. The expansion body is usually a conical or cylindrical plastic or metal component with one end connected to a metal tube and the other end capable of expansion.
When using expansion anchors, first drill a hole in the object to be fixed, and then insert the expansion anchor into the hole. When the expansion anchor is inserted into the hole, the metal tube is rotated to expand the expansion body and is fixed in the hole. The expansion force of the expansion body can provide strong fixing force to tightly connect the anchor bolt and the object.
Expansion anchors are suitable for a variety of materials, such as concrete, brick walls, and rock. They are commonly used for fixing and supporting buildings, bridges, roads and other structures.
However, it should be noted that the fixing force of expansion anchors is affected by factors such as hole diameter, hole depth, material strength and installation quality. Therefore, when using expansion anchors, it is necessary to select the appropriate model and installation method according to the specific situation to ensure the fixing effect and safety.
