1, its own quality is light. Light steel keel is a kind of light material.
2, good fire resistance. It is composed of light steel keel and 2~4 layer gypsum board, and its fireproof limit can reach 1.O ~ 1.6h. Therefore, the light steel keel has excellent fire protection performance.
3, the construction efficiency is higher. Because the light gauge steel keel is a kind of light material, it can adopt the assembly type construction method, therefore, its construction efficiency is higher.
4. The structure is safe and reliable. Because the light steel keel has such characteristics as high strength and large rigidity, the structure made of it is very safe and reliable.
5 、 good shock resistance. The partition wall is composed of light steel keel and ordinary plasterboard of 9 ~ 18mm thickness, and its longitudinal fracture load is 390 ~ 850N, so its impact resistance is good.
6, good seismic performance. The light steel keel and the surface layer are often fixed with the nail, the core pulling rivet and the sliding connecting piece of self tapping screw, and the utility model has good seismic performance. Under the action of earthquake shear, the partition only produces supporting sliding, but the light steel keel and the surface layer itself are very small and will not destroy.
7, can improve the heat insulation, sound insulation effect and indoor utilization rate. Because the light steel keel partition covers a small area, such as Q75 light steel keel and two layers of 12mm gypsum board partition, the width is only 99mm, and its heat insulation performance is far more than a brick wall. If in the light steel keel and then filled with rock wool and other insulation materials, the heat insulation effect can be equivalent to the thickness of 37mm brick wall. Usually in the entertainment, conference rooms, offices and other partitions or ceilings in the construction of such materials, not only can solve the problem of sound insulation and heat preservation, but also can improve indoor utilization.
