1. The main content of this atlas is the architectural construction method of hollow extruded fiber reinforced cement board (referred to as hollow extruded board) closed joint curtain wall project. Open joint curtain wall projects can refer to this atlas, but a reliable water conduction and drainage system should be installed, and waterproof protection measures should be adopted on the outside of the insulation layer of the main exterior wall. 2. The angle steel connectors, Z-shaped connectors, supporting angle steel, inner wire backing plate, Z-shaped connector fastening bolts, etc. in the hollow extruded panel curtain wall system are all standard accessories. If non-standard accessories are used, they should be calculated It can be adopted only after meeting the requirements. 3. The embedded parts, anchor bolts, rear embedded panels, angle steel picks, connecting bolts, curtain wall columns, curtain wall beams, etc. in the hollow extruded panel curtain wall system should be calculated and determined based on the actual conditions of the project.
