Description

Technical Field

[0001] The utility model relates to the technical field of lock-seam type metal roofs, in particular to a lock-seam type metal roof structure. Background Art

[0002] A lock-seam metal roof generally refers to a roof structure that uses metal sheets as roofing materials and is then connected and fixed by locking. Due to its economy and practicality, it is widely used in industrial and civil buildings. However, the existing lock-seam metal roof structure still has some disadvantages, such as insufficient stability after installation. After long-term use, the connection may become loose due to severe shaking in windy weather. In addition, the sealing between the metal roof panel and the fixings is not good enough, which is prone to water seepage. At the same time, workers have no standing point when performing roof maintenance, so they need to stand on the metal roof panel, which not only poses certain safety hazards but also easily causes the metal roof panel to sag. For this reason, we propose a lock-seam metal roof structure. Utility Model Content
