Abstract

This study involves a lightweight composite insulation structural component for civil air defense construction, aiming to solve the problems of alignment accuracy control and leakage prevention at the board joints during the installation of insulation boards. This structural component includes a shell, positioning module, sensing module, anti-misalignment module, closure module and leak-proof module. It assists in positioning and installing adjacent insulation boards and senses their alignment in real time. When the insulation board is misaligned, the anti-misalignment module automatically blocks the screw holes and forcibly interrupts the installation process. Fixation can only be carried out when the alignment meets the standard and the anti-misalignment piece is detached from the through hole, thereby ensuring the positional accuracy after installation. In addition, the structural components adopt the TG mortise and tenon type butt joint method. Compared with the flat head butt joint, it can effectively slow down the seepage of liquid through the board joints. Combined with the anti-leakage module, it can absorb the already seeped liquid, maximizing the delay of liquid erosion on the insulation system and extending the service life of the entire system. The present invention provides a reliable solution for the rapid, precise and durable installation of insulation structures in civil air defense projects and other construction fields by integrating positioning, error-proofing and leak-proofing functions.
