Description

Technical Field

[0001] The invention relates to the field of buildings, specifically to the field of building curtain walls, and in particular to a large-span curtain wall system. Background Art

[0002] The existing general glass curtain wall system can only achieve a small curtain wall span, weak stress, poor safety performance and cannot adapt to the shortcomings of large-span curtain walls. The existing conventional large-span aluminum-clad steel glass curtain walls have large column depths, are bulky and unsightly, occupy a large amount of indoor space, and have problems such as inconsistent proportions of beams and columns. Many large-span glass curtain walls also have large decorative lines outdoors, and keels need to be set to fix the large decorative lines, and indoor and outdoor cannot be taken into account. In summary, some existing glass curtain wall systems are weak in stress and cannot achieve large spans. Glass curtain wall systems that can achieve large spans have large depths, occupy indoor space, are unsightly, uncoordinated, and uneconomical.

[0003] For example, it is necessary to build a building structure with a large-scale, large-span curtain wall system. For example, the column spacing is 2160mm, the column span is as high as 17m, and the top is a steel structure that can only bear horizontal loads. Therefore, the curtain wall columns are compressed columns, and the force form is very unfavorable. Considering the indoor effect and actual use experience, the architect requires that the depth of the indoor curtain wall steel columns is not more than 200mm. For this type of glass curtain wall system, the traditional conventional glass curtain wall system cannot meet the force requirements. The traditional aluminum-clad steel system is used. The column depth must be more than 600mm to meet the force requirements. The indoor depth is very large and appears very bulky. It also occupies a large amount of indoor space, wastes indoor area, and the indoor columns are large, but the beams are small, which is very inconsistent. It is neither economical nor beautiful, and it cannot meet the architect's requirements for light and beautiful curtain walls. Summary of the invention
