Ceiling Construction: Light steel keel is mainly used to support and fix the indoor ceiling. In the ceiling system, it is divided into main keels and auxiliary keels. The main keel bears the main load – bearing task, and the auxiliary keel is used to fix the ceiling panel2. For example, in the decoration of hotels, office buildings, shopping malls and other places, a large number of light steel keel ceilings are often used. The common practice is to first install the main keel through hangers, and then install the auxiliary keel perpendicular to the main keel. Finally, the ceiling material such as gypsum board is fixed on the auxiliary keel.
Partition Wall Construction: It is mainly used for dividing and isolating indoor spaces and can be used in conjunction with gypsum boards, mineral wool boards and other boards to form partition walls of various shapes2. In office buildings, hotels and other places, in order to meet the needs of different space functions, light steel keel partition walls are often used to divide the space. The construction method is to first install the vertical keel and the horizontal keel on the ground and the top of the wall to form a framework, and then install the partition board on the framework.
Wall Construction: It is used for the construction of exterior and interior walls and can be combined with insulation materials, waterproof materials, decorative panels, etc. to form walls with functions such as insulation, waterproofing, and aesthetics2. In some modern buildings, especially in energy – saving buildings, light steel keel walls are widely used. The construction process is to install the light steel keel on the foundation, and then install the insulation material, waterproof material and decorative panel in sequence.
