Description

Technical Field

[0001] The utility model relates to the technical field of building roof corner waterproofing, in particular to a waterproof structure at a roof junction corner. Background Art

[0002] The layout of the waterproof structure at the traditional roof intersection corners is not reasonable. Usually only one layer of waterproof membrane is laid to cooperate with other structural layers. This makes it impossible to effectively prevent rainwater from flowing into the insulation layer through the weak link at the wall intersection at the vertical roof and the horizontal roof inner side intersection corner; not only that, the traditional solution also has a horizontal waterproof additional layer laid at the bottom of the waterproof membrane, but because the additional layer is laid in a horizontal state, it is also unable to effectively prevent rainwater from flowing into the insulation layer through the wall intersection. Therefore, the traditional solution has a series of problems such as short service life of the waterproof membrane and easy falling off of the mortar protective layer. Utility Model Content
