Abstract
The invention discloses a prefabricated lightweight steel-foam concrete composite wall and an application method thereof. The wall comprises a wallboard frame. The wallboard frame comprises first U-shaped lightweight steel, second U-shaped lightweight steel and third U-shaped lightweight steel which are arranged transversely in parallel. Fourth U-shaped lightweight steel and fifth U-shaped lightweight steel are arranged at the top ends and the bottom ends of the first U-shaped lightweight steel, the second U-shaped lightweight steel and the third U-shaped lightweight steel correspondingly. Pouring holes are formed in the fourth U-shaped lightweight steel. First wallboards are embedded on the two sides of the first U-shaped lightweight steel, the second U-shaped lightweight steel and the third U-shaped lightweight steel in the longitudinal direction. A cavity formed between the first wallboards and the wallboard frame is filled with foam concrete. The thermal insulation performance of the wall can be improved, and templates can also be saved by arranging fiber cement boards on the periphery of the wallboard frame, so that the prefabricated composite wall can be manufactured easily, the assembly degree is high, and the composite wall is suitable for industrialized production; and the cavity structure formed between the first wallboards and the wallboard frame is filled with the foam concrete, the shear strength and the bending strength of the whole wallboards are improved, and thermal insulation performance, sound insulation performance and fireproof performance of the wall are improved.
Description
[0001] Technical field: [0002] The invention relates to the technical field of construction engineering, in particular to an assembled light steel-foam concrete composite wall and its application method. [0003] Background technique: [0004] The traditional cold-formed thin-walled steel wall is a wall system in which the cold-formed thin-walled steel skeleton and light wall panels are connected by self-tapping screws as a load-bearing and maintenance structure. This kind of structural system has light weight and fast construction speed, but the thermal insulation, sound insulation and fireproof performance of the wall are poor, and the intermittent connection of self-tapping screws makes the integrity of the structure poor. In order to improve the above deficiencies, this paper proposes a light steel-foam concrete composite wall, which uses cold-formed thin-walled steel and cement board to support the formwork to form a wall cavity, and then the foamed concrete slurry poure...
