The undercut anchor with internal thread for a concealed flush or stand-off installation of heavy façade panels out of natural stone. Calibrated panels or reveal panels can be flush mounted and panel tolerances can be adjusted through the stand-off installation. Due to the internal thread, there is no protruding external thread. Thus panels can be prefabricated and transported in a space-saving manner. This improves the economic efficiency and flexibility of the system.
Advantages
The flush-mounted anchor allows for easy, economical construction of reveals.
Depending on the application, the user can choose between flush installation with an absolute anchoring depth, for instance for reveal panels, and stand-off installation technology with a constant remaining wall thickness that serves as a reference dimension to compensate panel thickness tolerances.
There is no protruding external thread, allowing a space-saving transportation of pre-fabricated façade panels.
The matching shape of the undercut anchor creates a inter-locking and stress-free fixing in the conical undercuted drill hole.
The fixing is not externally visible, creating a visually appealing façade surface.
Setting the anchor using undercut technology allows the user to select the best structural position in the façade panel. This significantly reduces the bending moment of the panel.
The anchor allows higher failure loads compared to common systems.
Applications
Exterior façades
Interior façades
Façade reveals
Functionality
The hole is either drilled to a constant reference dimension for the remaining wall thickness (RWT) or with an absolute anchoring depth.
