Carbon-Neutral Cement Boards: The Next Frontier in Sustainable Facades.

Focusing on "Carbon-Neutral Cement Boards: The Next Frontier in Sustainable Facades.", this paper starts from four stages: design review, material matching, process control and completion acceptance, and sorts out technical points and checklists that can be directly used for drawing review, on-site disclosure and acceptance records.

Selection of keel system

Light steel keel is divided into bearing keel, cladding keel and edge keel, and different parts play different roles. When selecting the type, the layer height, span, plate weight and fire and sound insulation requirements should be considered at the same time. The cladding keel cannot be used to replace the bearing keel .

Second, the matching of the system and accessories

III. Quality of accessories

Hangers, connectors and support cards should be in the same system as the keel, and the thickness of the galvanized layer meets the requirements. Mixing accessories from different manufacturers can easily produce matching gaps and reduce load-bearing capacity.

4. Selection check

• Check the keel size, wall thickness and galvanized layer.
• Confirm that the accessories are compatible with the keel system.
• Check the hanging points and anchoring method.
• Confirm that the typesetting is coordinated with the electromechanical points.

The keel system is the skeleton of the ceiling and partition wall. Only with accurate selection and matching accessories can the system performance be guaranteed.
