What Are the Anti-Detachment Measures for UHPC Exterior Wall Panels in High-Rise Residential Buildings? Qinglong UHPC Anti-Detachment Technology System

Preventing detachment of UHPC exterior wall panels on high-rise residential buildings requires comprehensive measures of "multiple connections + deformation accommodation + regular inspections." Each panel is fitted with no fewer than 4 connection points, with connector pull-out resistance ≥3kN and a safety factor ≥5. The connection system should provide three-dimensional adjustment capability (adjustment range ≥15mm) to accommodate structural deformation. A regular inspection system ensures hazards are identified promptly.

Wind pressure design is based on the 50-year return period wind pressure, with connectors verified through calculations. Seismic design meets the requirements of "no damage in minor earthquakes, repairable damage in moderate earthquakes, no collapse in major earthquakes." In a coastal high-rise residential project, after withstanding a typhoon, the UHPC curtain wall remained intact, while some tiles on projects of the same period fell off.

Key Points of Connection Design

≥4 connection points per panel; pull-out resistance ≥3kN; these key points ensure reliable connections.

Wind Pressure Resistance Measures

Designed for the 50-year return period wind pressure; connectors verified through calculations; these measures resist wind loads.

Seismic Design Considerations

Anti-detachment devices are installed; appropriate deformation is allowed; these considerations improve seismic performance.

Regular Inspection System

One full inspection per year; special inspections after typhoons and earthquakes; these systems identify hazards in a timely manner.

Preventing detachment is the safety bottom line. Qinglong UHPC provides multiple safeguards to protect lives.
