Description

Technical Field

[0001] The utility model relates to a construction project, in particular to a parapet wall structure. Background Art

[0002] The roof is an important part of the building envelope. As the top component of the entire building system, the roof parapet not only maintains safety but also decorates the facade. The traditional parapet is cast in situ with the roof structure slab at the bottom, and bricks are used at the top. The inconsistent materials of the two are prone to shrinkage and deformation, and cracks are formed, leading to water leakage. Rainwater directly penetrates through the parapet to the waterproof layer, and leaks into the room through the cracks in the roof slab.

[0003] In addition, traditional roof parapets take a long time to construct, have complex construction procedures, require formwork, are difficult to control in quality, and are easily cracked due to the influence of temperature, wind loads, rain erosion, etc. Utility Model Content

[0011] Furthermore, a tongue-and-groove is provided between the parapet and the counter-ridge, and the tongue-and-groove is filled with waterproof glue.

[0012] Furthermore, a downwardly inclined protrusion is provided on the outer side of the bottom of the parapet, and a downwardly inclined chamfer is provided on the outer side of the top of the anti-ridge, and the protrusion matches the chamfer to form the tongue and groove.
