Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to the field of waterproof structure technology for roof vent pipes, specifically referring to a waterproof membrane protection structure for the outer side of a roof vent pipe. Background Technology
[0002] Building construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction.
[0003] During building construction, waterproofing of roof vent pipes is frequently involved. These vent pipes are installed vertically, while the roof slab is horizontally fitted over the outer side of the vent pipe. The conventional waterproofing method involves pouring a slope-forming layer on the roof slab and over the outer side of the vent pipe, then pouring a leveling layer on top of the slope and over the outer side of the vent pipe. A horizontal waterproofing membrane is then laid on the leveling layer, and a vertical waterproofing membrane is laid over the outer side of the vent pipe. Finally, a horizontal waterproofing layer is laid on top of the leveling layer and the horizontal waterproofing membrane. A vertical waterproof membrane layer is laid on the outer side of the horizontal waterproof membrane layer and the additional vertical waterproof membrane layer. An insulation layer is poured on the lower edge of the vertical waterproof membrane layer on top of the horizontal waterproof membrane layer. A horizontal protective layer is poured on the lower edge of the vertical waterproof membrane layer on top of the insulation layer, and a vertical protective layer is poured on the outer side of the vertical waterproof membrane layer. The vertical protective layer is placed on top of the horizontal protective layer. According to specifications and conventional design practices, the vertical protective layer of the vertical waterproof membrane layer outside the roof vent pipe is often applied using mortar. However, over time, the mortar layer often becomes hollow and peels off, causing damage to the waterproof structure and making leakage more likely.
[0004] Therefore, it is desirable to provide an external waterproof membrane protection structure for the outer side of the roof vent pipe, which can protect the fireproof membrane, is not easily damaged, and effectively prevent water leakage caused by damage to the waterproof structure.
