Double-Curved GRC Panel to Steel Structure Connection Angle Adjustment Technology: Qinglong GRC 3D Adjustable Connection System

The connection of double-curved GRC panels to the steel structure adopts a three-dimensional adjustable system, allowing an angle adjustment range of ±5°, planar adjustment of ±15mm, and elevation adjustment of ±10mm. Through a combination of ball hinge connectors (rotation angle ≥8°), slotted hole design (adjustment ±20mm), and shim sets (thickness 1-10mm), precise angle adjustment and reliable connection are achieved.

Connection design: calculates angle changes under temperature deformation, wind loads, and seismic action, reserving adjustment allowance. In a double-curved roof project, the maximum adjustment angle was 3.5°, and the adjustable system perfectly achieved the designed shape with safe and reliable connections. Qinglong GRC adjustable connection technology adapts to various complex working conditions.

Ball Hinge Connection Technology

Ball hinge rotation angle ≥8°, meeting deformation requirements; contact area ≥70%, ensuring load-bearing capacity; self-lubricating design reduces friction; anti-loosening devices ensure safety and reliability. Ball hinges provide multi-directional rotation.

Slotted Hole Design

Slot hole length ≥30mm provides adjustment capacity; edge chamfering reduces stress concentration; installation sequence: fix first, then adjust; anti-slip shims prevent loosening. Slot holes allow planar adjustment.

Shim Adjustment System

Shim thickness combinations of 1, 2, 5, 10mm; stainless steel material for corrosion resistance; on-site cutting to meet requirements; grouped use ensures flatness. Shims achieve precise elevation adjustment.

Locking and Anti-Loosening Measures

Torque wrenches control preload; anti-loosening washers prevent vibration loosening; secondary tightening ensures reliability; regular inspection and timely maintenance. Locking measures ensure long-term safety.

Adjustable connection is key to double-curved panel installation. Qinglong GRC's professional system achieves precise and reliable connections.
