Description

Technical Field

[0001] The utility model relates to the technical field of parapet wall flashing surface structures, in particular to a parapet wall flashing surface waterproof structure. Background Art

[0002] The parapet, also known as the eaves wall, is a low wall around the roof of a building. Its main function is to maintain safety. With the development of construction projects, in order to make the roof waterproof structure more stable and reduce the occurrence of cracks at the intersection between the roof and the parapet, the roof waterproof layer is usually extended to continuously cover the intersection with the parapet and the vertical surface. This waterproof treatment is called parapet flashing, and the vertical surface between the parapet and the roof is also called the flashing surface.

[0003] The general flashing treatment is to open a groove on the side wall of the parapet flashing surface, then glue half of the waterproof membrane to the roof and the other half to the intersection of the roof and the parapet, extend the waterproof membrane to the groove on the vertical surface of the parapet, fill the groove with sealing material, and then apply a mortar layer on the outer layer.

[0004] However, when the parapet is subject to external temperature differences, it will expand and contract with temperature. Since the groove part lacks a wall, the force it bears is inconsistent with that of other parts. Therefore, the mortar layer in the groove part on the flashing surface of the parapet will have irregular horizontal cracks, causing rainwater to penetrate through the groove part, thereby reducing the waterproof effect of the parapet.
