What Are the Connection Methods Between GRC Curtain Walls and the Main Structure? Qinglong GRC Connection Technology System Explained

GRC curtain wall connections to the main structure are mainly divided into three categories: point connection, line connection, and surface connection, selected according to curtain wall form, structural characteristics, and usage requirements. Point connection is suitable for unitized curtain walls, with 4-6 connection points per panel; line connection is suitable for strip panels, with connection points arranged continuously; surface connection is suitable for large panels, with multiple points evenly distributed.

In terms of connection system design, Qinglong GRC adopts mature connection technology: the seismic design meets the 8-degree fortification requirement with an allowable inter-story displacement of 1/200; the wind pressure resistance design meets a basic wind pressure of 0.65kPa; anti-corrosion treatment uses hot-dip galvanizing or stainless steel. The safety factor of connectors is ≥2.5, and fatigue performance has passed 2 million cycle tests. These designs ensure safe and reliable connections.

Point Connection System Features

Each panel is equipped with 4-6 connection points at a spacing ≤600mm; three-dimensional adjustable hangers are used with an adjustment range of ±15mm; these features make it suitable for unitized installation.

Applicable Conditions for Line Connection

Suitable for strip panels, with connection point spacing ≤800mm; channel-type embedded parts are used to achieve continuous connection; these conditions ensure the stability of linear components.

Technical Points of Surface Connection

Large panels feature multiple points evenly distributed with point spacing ≤1.2m; uniform load transfer is adopted to avoid stress concentration; these points ensure the safety of large-area panels.

Special Requirements for Seismic Design

Anti-detachment devices are installed to prevent panels from falling during earthquakes; elastic connections are used to absorb deformation energy; these requirements improve seismic performance.

Connection methods require professional design. Qinglong GRC provides safe and reliable connection solutions.
