AI Technical Summary

Technical Problem

Existing glass curtain wall shading solutions for super high-rise buildings have shortcomings in terms of safety, aesthetics, and economy. In particular, in coastal areas where typhoons are frequent, external shading components are at risk of falling off, and mixed-use buildings cannot meet the energy-saving design requirements of both residential and public buildings.

Method used

The structure adopts a multi-layer glass component structure, including an outer layer of sunshade laminated glass component and an energy-saving calculation unit, which is fixed into an integrated curtain wall by an aluminum alloy support frame. The outer glass acts as a baffle-type external sunshade component and does not participate in the energy-saving calculation, while the middle layer participates in the energy-saving calculation. The overall structure has no overhanging components, which meets the requirements for sunshade performance and energy saving.

Benefits of technology

It achieves a shading coefficient SD≤0.8, meets energy-saving design requirements, avoids the risk of external components falling off, reduces installation and maintenance costs, and balances the aesthetics and safety of the building facade. It is suitable for super high-rise buildings in hot summer and warm winter regions.

Abstract

The application provides a sunshade structure of a super-high residential building glass curtain wall, comprising an aluminum alloy support frame, a fixed connection assembly and a multilayer glass assembly. The multilayer glass assembly is sequentially provided with an outer sunshade laminated glass assembly and an energy-saving calculation unit from the outdoor side to the indoor side. The outer sunshade laminated glass assembly is double-tempered laminated LOW-E glass, which is used as a baffle type outer sunshade component and does not participate in building energy-saving thermal calculation. The energy-saving calculation unit participates in building energy-saving thermal calculation, and the two are fixed as a curtain wall structure of an integrated non-overhanging component through the aluminum alloy support frame. The structure uses the outer double-tempered laminated LOW-E glass as a baffle type outer sunshade component to replace the traditional overhanging sunshade board, louver and other overhanging sunshade components, fundamentally avoiding the safety risk of aging and falling of the overhanging sunshade component in the super-high environment, and is especially suitable for the use scene of super-high buildings in hot summer and warm winter coastal typhoon-prone areas.
