TECHNICAL FIELD
[0001] The present application belongs to the technical field of movable screen installation, and particularly relates to an installation process of a large-area movable screen. BACKGROUND
[0002] The large-area movable screen is widely used in public spaces such as hotel banquet halls, exhibition centers, office buildings and large shopping malls due to its advantages of flexible adjustment of space layout and adaptation to multi-scene use requirements. With the continuous expansion of building space, the size and weight of the movable screen also increase, and the traditional installation process gradually exposes many technical pain points, which are difficult to meet the current high-standard construction and use requirements. The traditional process relies on manual experience in the positioning stage, lacks clear precision control standards, and the deviation of the horizontal line and the vertical control line often exceeds 5mm, resulting in the inclination of the subsequent keel installation. At the same time, the connection between the fixed keel and the ground only uses simple bolts, without setting reinforcing keels for load-bearing requirements, and the rust-proof and fire-proof treatment is not comprehensive, which is prone to keel rusting, structure loosening, screen deformation and collapse risk due to changes in environmental humidity and external force impact in long-term use. The joint treatment of adjacent screen panels lacks standardized processes, and the traditional process does not clearly specify the lofting mark and angle requirements of the inclined hole, resulting in a gap width difference of more than 3mm after the panel splicing, and the installation of the decorative plate and the keel without special installation slot design, only through surface fitting and fixing, which is prone to decorative plate edge lifting and falling. In addition, the installation of the decorative line frame does not consider the adaptability after the corner plastering, and often has the problem of large gap between the line frame and the screen, which affects the overall aesthetic appearance.
