Technical Field

[0001] The invention relates to the technical field of construction engineering, in particular to a reinforcement-free sprayed composite wall panel and a construction method thereof. Background Art

[0002] Sprayed gypsum composite walls are becoming increasingly popular in the market due to their light weight, high strength, excellent sound insulation and fire resistance, and the use of industrial gypsum waste as a cementitious material.

[0003] For example, the invention with publication number CN113463796B discloses a composite wall structure and construction method for a lightweight steel keel with a special-shaped cross-section. This invention introduces a lightweight steel keel with a special-shaped cross-section as the skeletal support for a lightweight steel keel spray-cast composite wall. Its construction method requires a reinforcement process. However, lightweight steel keels with special-shaped cross-sections are relatively expensive, and the reinforcement process required during construction results in high overall costs. Reducing the material and construction costs of composite walls with lightweight steel keels with special-shaped cross-sections is crucial to the market viability of spray-cast gypsum composite wall products.
