Reinforced double-lockrand fusion type roof occlusion structure

The utility model provides a reinforced double-lockrand fusion type roof occlusion structure, which relates to the technical field of metal roof installation and comprises roof panels, fusion lockrand occlusion structures are arranged between the adjacent roof panels, and the fusion lockrand occlusion structures are used for connecting the adjacent roof panels. According to the utility model, a traditional vertical overlock meshing structure is combined with a 360-degree novel overlock meshing structure, so that a vertical-side double-meshing connection mode is realized, and when temperature changes, the metal roof board can freely stretch out and draw back through the fixed seat, so that the metal roof board can be fixed on the fixed seat; according to the invention, deformation caused by temperature stress is not generated, the reliability of roof performance is ensured, the air tightness and water tightness of a metal roof system are improved in a multi-occlusion overlapping manner, and the stability, dura
