Description

Technical Field

[0001] This utility model belongs to the field of parapet wall construction technology, and in particular relates to a combined ultra-high parapet wall structure based on metal exterior wall panels. Background Technology

[0002] Parapet walls are common structural components at the edge of building roofs, typically appearing as a low wall around the perimeter of the roof. Their main functions include preventing falls from the roof, sealing the roof waterproofing layer, limiting rainwater runoff, and supporting some ancillary structures. In industrial buildings, especially electronics factories, large warehouses, or cleanrooms, the height of the parapet wall is often influenced by multiple factors such as decorative design, the arrangement of exterior wall panels, and roof drainage requirements, resulting in what is known as an "extra-high parapet wall" structure.

[0003] In traditional building construction, super-high parapet walls are mainly constructed using monolithic cast-in-place concrete structures. While this approach offers good structural stability, it has revealed numerous problems in actual projects. First, because parapet walls are often located at the edge of the building's roof and have one side exposed to the air, it is difficult to arrange effective edge protection and working platforms during the construction phase. Especially when the height exceeds 3 meters, the construction safety risks increase significantly, requiring extensive scaffolding and reinforcement measures to ensure working conditions, resulting in complex construction organization and high costs. Second, during the formwork erection and concrete pouring process of super-high parapet walls, issues such as the slender structure, dense reinforcement, and insufficient formwork rigidity often lead to problems like formwork bursting, grout leakage, bulging, or deformation. Especially when pouring a large-volume thin wall in one go, the concrete's self-weight and lateral pressure are significant; improper handling will seriously affect the quality of the structure's formation, leading to potential problems such as leakage, cracking, or waterproofing failure. Furthermore, concrete parapet wall structures often lack internal beam-column structures, belonging to a cantilevered high wall design, resulting in a single structural load and limited resistance to wind pressure and horizontal loads. Without secondary structural measures, such as supports or reinforcing ribs, structural deformation is highly likely, especially in areas with high wind loads, such as the southeast coast or open areas, where it is difficult to meet code requirements. Furthermore, since metal exterior wall panels and other cladding materials need to be installed on ultra-high parapet walls, their anchoring points mostly rely on post-installed expansion bolts or nails. If the foundation concrete is not of sufficient quality, it will reduce the overall stability of the cladding system. Utility Model Content
