Description

Technical Field

[0001] This invention relates to the field of architectural decoration, and more particularly to a unitized curtain wall window system with a prestress adjustment module. Background Technology

[0002] The current dimensions of aluminum alloy window mullions should be determined by calculation. When the width and height of the window opening increase, the mullion cross-section must be increased to meet the structural strength and rigidity requirements. This requires multiple sets of molds to match the engineering application. The molds need to be customized, which is expensive and greatly increases the project cost. Moreover, the different cross-sectional shapes and dimensions greatly affect the final decorative effect. At the same time, aluminum alloy horizontal strip windows are usually installed by fixing the mullions, installing the horizontal mullions, frame beams and glass, which is slow.
