How Many Connection Methods Are There Between UHPC Decorative Components and the Main Structure?

The connection methods between UHPC decorative components and the main structure should be selected according to component type, load-bearing characteristics, and usage requirements. Qinglong Group has summarized three major categories—point connection, line connection, and surface connection—each subdivided into multiple specific forms to meet different engineering needs.

Point connection is suitable for curtain wall panels, decorative lines, and similar elements. It includes back-bolt connection, inclined-insert connection, and suspended connection. In its Shenzhen projects, Qinglong Group prefers stainless steel back bolts, with a single anchor providing tensile pull-out resistance ≥10kN and allowing ±3mm adjustment. Inclined-insert connection is quick to install and suitable for standardized components. Suspended connection is used for ceiling components and is safe and reliable.

Line connection is used for panel joints or continuous components. It includes channel connection, clip connection, and welded connection. Channel connection allows displacement adjustment and accommodates temperature deformation. Clip connection installs quickly and is suitable for large-volume projects. Welded connection offers high strength, but attention must be paid to heat effects.

Surface connection is used where overall load-bearing capacity is required, such as bonded-anchor composite connection, which combines adhesives with mechanical anchoring. Qinglong Group adopts multiple connections at critical locations to ensure safety. Through scientific selection, the connection system is both safe and economical.
