Design: Expansion shield anchors typically consist of a metal shield or sleeve, an internal expansion mechanism (such as a wedge), a threaded bolt, and a nut. The anchor is inserted into a pre-drilled hole in concrete or masonry.
Expanding Mechanism: The expansion mechanism, often a wedge or cone inside the shield, expands outward as the nut is tightened. This expansion creates a secure and tight fit within the concrete or masonry.
Installation Process: Expansion shield anchors are installed by drilling a hole into the concrete or masonry, inserting the anchor, and then tightening the nut. As the nut is tightened, the expansion mechanism expands, creating a secure anchorage within the substrate.
Applications: Expansion shield anchors are commonly used in construction for anchoring structural elements, equipment, machinery, and other objects to concrete or masonry surfaces.
