Description

Technical Field

[0002] Building construction refers to the production activities during the implementation phase of a project. It is the process of constructing various buildings. It can also be said to be the process of transforming the various lines on the design drawings into physical objects at the designated location. It includes foundation construction, main structure construction, roof construction, and decorative construction.

[0003] During construction, roof ventilation shafts are often involved. Since the 1980s, roof leakage has become a prominent issue in my country's construction projects, directly impacting the functionality and safety of buildings. The gaps between the roof ventilation shaft pipes and the structure are common leak points on roofs. During construction, they are often sealed with masonry mortar, making construction quality difficult to guarantee and leaving hidden dangers for roof leakage. Furthermore, ventilation shaft pipes run through the entire building. Once a leak occurs, the more complex the building structure, the more difficult it is to identify the leak. During maintenance, this often results in leaks year after year, followed by repairs year after year, and leaks year after year.

[0004] Therefore, in order to reduce the problem of roof water leakage caused by the gap between the roof ventilation shaft pipe and the structure, it is necessary to provide a roof ventilation shaft waterproof structure, which can significantly reduce the leakage problem caused by the loose sealing of the roof ventilation shaft pipe structure without significantly increasing the construction cost.
