Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and in particular relates to an assembled connection structure of phosphogypsum exterior wall panels. Background Art

[0002] Phosphogypsum exterior wallboard is a new type of wall material for the resource utilization of phosphogypsum solid waste. The size of phosphogypsum exterior wallboard (hereinafter referred to as wallboard) is 2400*600*120mm, and the weight is about 141Kg. During installation, the wallboard is fixed to the main structure (beams and columns) of the wall through U-shaped clips, and the adjacent wallboards are nailed to the 50*50*1mm square galvanized plate. In order to improve the heavy weight, laborious manual handling, difficult installation and low installation efficiency of phosphogypsum exterior wallboard, the factory-produced wallboard with a size of 2400*600*60mm is used for double-layer splicing and assembly installation. Existing assembly parts such as U-shaped clips have few connection points and are not stable to install. The splicing gap between double-layer wallboards and the gap between adjacent wallboards are easy to crack when cement mortar is filled, causing water leakage in the exterior wall; U-shaped clips and other assembly parts are easy to rust on the outside of the wallboard, affecting the safety of the wallboard; after installation, the assembly parts will be partially damaged when the water and electricity grooves are cut and the wire pipes are buried.
