AI Technical Summary
The existing building envelope has a large load, resulting in large beam and column sections, high steel consumption, high cost, and complex transportation and installation.
The building envelope adopts a combined structure of inner cement pressure board layer, outer cement pressure board layer, insulation layer, exterior decorative panel and waterproof layer, combined with frame and vapor barrier to form a lightweight, ultra-low energy consumption building envelope. The fasteners are reduced by staggered joints and thermal break anchor bolts.
It achieves lightweight and low-energy building envelope, reduces structural load and cost, simplifies transportation and installation, and has good airtightness and thermal insulation performance.
