[0002] Light steel wall is a wall system with cold-bent thin-walled steel (light steel keel) as the main load-bearing structure. It is widely used in modern buildings such as light steel villas and integrated houses.

[0003] The modular phosphogypsum wall with light steel keel and non-removable formwork provided by publication number CN216766391U includes trough plates, vertical beams, horizontal beams, connecting ribs and phosphogypsum formwork. A rectangular grid-shaped light steel keel is formed by passing multiple horizontal beams through slurry flow holes on multiple vertical beams. The trough plates are located at the upper and lower ends of the light steel keel and are connected to them. The connecting ribs are connected and fixed to the vertical beams and horizontal beams. The phosphogypsum formwork is located on both sides of the light steel keel and is connected and sealed to them. The vertical beams at both ends of the light steel keel are fixed to the wall columns, the trough plates are fixed to the load-bearing beams and floor partitions, and then the light steel keel is filled with phosphogypsum foam slurry.

[0004] However, when assembling and using the above-mentioned combined light steel keel wall module, when assembling the phosphogypsum formwork, the volume of the gypsum board is large, and some of the phosphogypsum formwork needs to be installed at a high position.
