This invention discloses an integrated twisted decorative wall structure with seaweed-like surface decoration and its construction method. The decorative section of the GRG board surface layer is composed of stacked C-shaped cantilever panels. The seaweed-like cantilever decorative panels are integrally formed with the cantilever panels, and their cantilever length and span gradually change from bottom to top, forming a dynamic three-dimensional decorative surface. During construction, a parametric digital model is first established to drive the design, and the surface layer is divided into prefabricated GRG unit blocks for factory production. T-shaped connectors are pre-embedded on the back of the unit blocks. On-site, the unit blocks are installed on the reinforced decorative keel using adjustable cantilever connecting beams, and the precise positioning is achieved using a total station with the tip of the cantilever decorative panel as a reference to ensure accurate shaping. This invention solves the strength problem of large cantilever GRG materials through a stepped, stacked, reinforced structure, and achieves a safe, precise, and efficient presentation of complex and dynamic shapes through digital design and prefabricated assembly construction.
