Description

TECHNICAL FIELD

[0001] The present application relates to the field of architecture, in particular to a wall system of vertically arranged metal sandwich panels. BACKGROUND

[0002] The outer wall is an important vertical component that separates the interior and exterior of a building, maintains the relative independence of the interior environment of the theme building, and is the main content of architectural design and construction. The parapet wall is a way to connect the roof and the outer wall, which serves as a barrier on the roof or a measure to shape the exterior of the building, prevents people from falling, and decorates the building facade. It also has a waterproof function.

[0003] As an external structure of a building, the outer wall and the parapet wall are exposed to the air and are greatly affected by natural factors. The metal sandwich panel, as a new type of lightweight hollow sandwich structure with "two panels sandwiching a core panel", is widely used in theme parks, industrial buildings and other buildings due to its good heat preservation, fireproofing and sound insulation properties.

[0004] At present, the metal sandwich panel in the outer wall and the parapet wall is affected by the limitations of factory processing technology. The metal sandwich panel is folded on the long side to meet the needs of installation, insertion and flashing, but the short side is not folded. Therefore, the current installation of metal sandwich panels is mostly horizontal, and there is no standard and mature vertical installation technology. Moreover, due to the limitations of the characteristics of the panel, the standard panel width of the metal sandwich panel can only be installed from the edge one by one from bottom to top, and cannot be simultaneously constructed.

[0005] In the outer wall, water seepage in gaps, leakage in openings, deformation, cracks and leakage at the corner closure are common quality problems. There is no mature method for preventing water seepage in gaps of large vertical panel width metal sandwich panels, no mature standard waterproof structure for openings across vertical joints, and no mature processing technology for corner closure of large vertical panel width metal sandwich panels. The limitations of technology restrict the pursuit of visual effects of vertical arrangement in architectural design.

[0006] The parapet wall is mostly a reinforced concrete structure with good waterproof performance and mature construction method. However, steel structure and metal sandwich panel outer wall parapet walls are mostly exposed to the air and greatly affected by natural factors. There are common quality problems such as deformation, cracking and leakage at the joint. Moreover, the rainwater system design of the parapet wall and the building roof is an important part of building water supply and drainage design, and the rainwater inlet is an important part that cannot be ignored. At present, the materials and forms of the rainwater inlet are single and cannot meet the design requirements of high appearance and special shape of the building facade. The rainwater inlet installed on the metal sandwich panel outer wall often has joint leakage and installation safety hazards. SUMMARY

[0007] The present application aims to solve the above problems, and provides a wall system of vertically arranged metal sandwich plate, which can effectively solve the high-standard sound insulation requirements and exterior decoration needs of high-quality theme parks and industrial plant outer walls, and can achieve better exterior effect compared with conventional systems, and facilitate the installation of sound insulation materials.
