Description
Technical Field
[0001] The utility model relates to the technical field of building curtain walls, in particular to an ultra-large width steel column curtain wall system. Background Art
[0002] The exposed frame glass curtain wall is a glass curtain wall with metal frame components exposed on the outer surface. Its characteristic is that the aluminum alloy profile itself has the dual functions of skeleton structure and fixing glass. The exposed frame glass curtain wall is the most traditional form, the most widely used, and has reliable working performance. However, if the width of the glass curtain wall is too large, the aluminum alloy keel is difficult to meet the requirements. And now people have higher and higher requirements for its decoration, not only requiring lightness and transparency, energy saving and environmental protection, but also requiring unique shape and low cost.
[0003] Traditional glass curtain wall frame systems usually use aluminum alloy profiles, which are connected by bolts. The frame is easy to deform. When the span of the glass curtain wall support structure is large or the plate is large, the strength of the aluminum alloy profile is low, and the required aluminum profile section is large. When the large section still cannot meet the force requirements, steel-aluminum combination or aluminum alloy profile lined with steel pipes are usually used. However, these two methods not only bring inconvenience to processing, construction and installation, but also easily cause electrochemical corrosion. In addition, the combination of multiple profiles increases the cost of the glass curtain wall. In addition, due to the low melting point and low strength of aluminum alloy, the actual use results in large cross-sections, more materials, high costs, and short lifespan, which not only affects the permeability but also is not durable.
[0004] Therefore, we proposed an ultra-wide steel column curtain wall system that can solve the above problems well. Utility Model Content
