Description
Technical Field
[0001] This utility model relates to the field of roof construction technology, and in particular to a construction node at the end of a steel structure roof ridge gable. Background Technology
[0002] In steel structure roof construction, the junction of the ridge and gable is a weak point in terms of waterproofing and structural strength. In existing technologies, this part often adopts the traditional node structure of "simple cover plate plus sealant". However, the ridge purlins are mostly single rectangular cross sections, and the connection with the cover plate relies solely on rivets for fixation. There is a lack of pre-limiting structure, which makes it easy to shift during installation. Moreover, the joints rely on only a single layer of sealant, which is prone to aging and cracking after long-term temperature changes and rain erosion, resulting in water leakage. The end caps of the gable end are mostly flat structures, which have poor fit with the roof panel and ridge cover plate. The gaps are prone to rainwater accumulation, and there is no special reinforcement structure. After long-term use, they are prone to loosening due to stress deformation. The connection between the trim and the end caps and cover plates lacks matching grooves. The sealing relies on manual application of the sealant layer, which is inefficient and the sealing effect is unstable, making it difficult to meet the long-term use requirements of the roof.
