It ensures the standardized design, factory production and convenient post-assembly construction of composite wall panels.

Specifically, the cold-formed thin-walled steel is usually a cold-formed thin-walled galvanized steel sheet and/or a galvanized steel sheet. Usually, U-shaped cold-formed thin-walled steel and C-shaped cold-formed thin-walled steel are used to make longitudinal support frame 1, so as to facilitate the connection with surrounding walls, keel columns and upper and lower beams, and can also be used as a template for concrete pouring.

Specifically, fiber cement board and/or reinforced expansion mesh can be used as the dismantling-free panel 2 . Fiber cement board is a cement slab for construction produced with cement as the basic material and adhesive, and mineral fiber cement and other fiber cement as reinforcement materials. Enhance the strength of the composite wallboard, improve the physical properties of buildings such as heat insulation, sound insulation, fire prevention and moisture resistance.

The reinforced expanded mesh is a completely non-contact expanded expanded mesh made of steel strips that are cut and stretched by professional machines. The material is galvanized strip steel or 304 stainless steel. Tensile strength, while longitudinal stiffeners allow for uniform depth of application over large areas of depth. The use of rib expansion mesh is used to enhance the strength of the composite wallboard and improve its safety performance and seismic performance. When the reinforced expansion mesh is used for pouring the wall, the steel bars are arranged horizontally on the longitudinal support frame, the expansion mesh is fixed on the longitudinal support frame, the pouring model is formed, and the concrete is poured. Longitudinal support frame, steel bar, expansion mesh and concrete are integrated to form a wall with good crack resistance, earthquake resistance and shear resistance. The use of the expansion net eliminates the process of removing the formwork, increases the construction space, shortens the construction period, and enables the wall panel to have better mechanical performance.

The polystyrene lightweight concrete filled in the middle of the wallboard is to add polystyrene particles to the modified ordinary concrete, so that the polystyrene particles are dispersed in the lightweight concrete slurry, and after the cement is cured, it forms a thermal insulation material. Lightweight concrete. Polystyrene particles, also known as expanded polystyrene particles, are made of expandable polystyrene resin beads as the basic raw material for expansion and foaming. Due to the large number of closed air cells in the polystyrene lightweight concrete and the low thermal conductivity of the polystyrene particles, the polystyrene lightweight concrete has excellent thermal insulation performance. At the same time, because the main material of the polystyrene lightweight concrete is cement material, and the polystyrene particles are wrapped in the cement, the polystyrene lightweight concrete has the characteristics of non-burning and non-aging. The use of polystyrene lightweight concrete as the filler in the middle of the wallboard can effectively improve the physical properties of the wallboard such as thermal insulation, sound insulation, fire prevention, and moisture resistance.
