Adjustable 3D Mounting Unitized Curtain Wall Customized Unitised Glazing System

Unitized Curtain Wall Bracket Hook-connection System is the core mechanical connection system between curtain wall units and the building's main structure, specifically developed to achieve safe hoisting, three-dimensional fine adjustment, and long-term load transfer for large prefabricated curtain wall units. The system employs high-strength forged aluminum alloy or stainless steel cast hook components, forming a dynamically adjustable interface with the building's embedded parts through a "floating" fishhook-shaped connection mechanism. Its innovative four-dimensional adjustment mechanism (horizontal X/Y axis, vertical Z axis, and rotational angle) allows units to achieve displacement compensation of up to ±25mm and deflection correction of ±1.5° during installation, effectively accommodating construction tolerances of the main structure and foundation settlement deformations.

The system components are designed through topology optimization and validated via finite element simulation, with a single hook node achieving a tensile load capacity of 45kN and a shear load capacity of 60kN. It is equipped with self-locking anti-release latches and anti-vibration spring devices. All metal parts undergo marine-grade anti-corrosion treatment (complying with ISO 12944 C5-M standards), making it particularly suitable for coastal high-salt-fog or industrial pollution environments. The connection interface features multiple buffering layers: the first level consists of high-toughness nylon gasket sets to absorb micro-displacements caused by wind vibrations; the second level includes stainless steel disc springs to resist thermal stress; and the third level uses rubber damping blocks to mitigate impact energy during seismic events.

This hook-connection system supports a "hang-first, fix-later" rapid installation process, with a daily hoisting efficiency of up to 100 unit modules using a single machine, eliminating the need for on-site welding. Its modular design is compatible with various building substrates such as concrete, steel structures, and timber frames, and achieves millimeter-level pre-matching of embedded parts and hook points through BIM modeling. Suitable for super-tall landmark buildings, large-span spatial structures, and existing building curtain wall renovation projects, it redefines the mechanical interaction between curtain wall units and the building structure with industrial-grade connection precision and reliability.
