Roofing parapet water-floating structure and construction method thereof

Abstract

The invention discloses a roofing parapet water-floating structure and a construction method thereof and relates to the technical field of parapet waterproof construction. A negative curved reinforcement is used for being bound with a longitudinal rebar in a parapet, and after a formwork is mounted, an overhanging eave in the inner side of the parapet and an olecranon convex eave at the lower end of the overhanging eave are formed through integrated pouring. A press felt groove is formed in the wall surface below. A screed-coat is smeared on a roofing heat preservation layer and the vertical face, below the overhanging eave, of the parapet. A waterproof layer is laid above the screed-coat, and a half header at the upper end of the waterproof layer is arranged in the press felt groove. A protecting layer is laid on the horizontal face of the screed-coat, a special-shaped extruded plate is pasted below the overhanging eave, the upper end of the special-shaped extruded plate is tightly attached to the overhanging eave, the vertical face of the special-shaped extruded plate is tightly attached to the portion, on the parapet, of the screed-coat, and the lower end of the special-shaped extruded plate is tightly attached to the protecting layer. A partition joint filled with gland packing is formed in the protecting layer on the outer side of the special-shaped extruded plate, and the special-shaped extruded plate is externally bonded with an anti-crack layer. Through the overhanging eave and the olecranon convex eave which are built during construction of the parapet, rainwater can be prevented from seeping from the half header of the protecting layer, the water-floating structure at the root of the parapet is protected against collision and treading, and integrality and rigidity of a decorating layer are improved.

AI Technical Summary

Benefits of technology

This technology prevents rainwater or other liquids from entering through gaps between layers inside an architectural feature called a sparer's hood (a type of shelf). It also helps maintain its structurally soundness while being durable against damage caused by environmental factors such as snow loadings. Additionally, it makes sure there are no cracks where liquid could leak out when subjected to impact forces like collisions with vehicles. Overall, this design enhances the overall appearance of buildings without compromising their safety measures.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the durability and reliance of water proof closures made from conventional materials such as steel rods embedded within concrete walls during building constructions due to their potential environmental issues caused by moisture intrusion into these components overtime.
