精制钢在大跨度玻璃幕墙中应用与性能分析

Application and Performance Analysis of Refined Steel in Large Span Glass Curtain Wall

摘要

随着中国社会经济的迅猛发展和城市化进程的加速，建筑行业迎来了前所未有的发展机遇。玻璃幕墙作为现代建筑的重要元素，因其能够赋予建筑通透感和美观性，已被广泛应用于建筑外立面设计中。尤其在大跨度、大分格的玻璃幕墙中，这种优势更为显著。然而，大跨度设计对主受力龙骨的力学性能提出了更高要求。考虑到钢的强度是铝合金的3倍，且价格更为经济，从性价比和受力性能出发，大跨度玻璃幕墙的龙骨常选用钢龙骨。传统钢管的冷弯加工方式往往导致截面圆角过大，影响室内可视面的美观。随着加工工艺的进步，如热压、精细打磨和焊接等技术的应用，钢管截面已能满足设计要求的圆角精度。论文基于实际工程经验和材料特性，深入探讨大跨度玻璃幕墙中采用高精钢（精制钢）龙骨替代传统铝合金龙骨的可行性及其优势。

Abstract

With the rapid development of China’s social economy and the acceleration of urbanization, the construction industry has ushered in unprecedented opportunities for development. As an important element of modern architecture, glass curtain wall has been widely used in the design of building facades because it can give the building a sense of transparency and aesthetics. Especially in the large-span, large-scale glass curtain wall, this advantage is more significant. However, the large-span design puts forward higher requirements on the mechanical properties of the main force keel. Considering that the strength of steel is three times that of aluminum alloy and the price is more economical, steel keel is often used for the keel of long-span glass curtain wall from the perspective of cost performance and mechanical performance. The traditional cold bending processing method of steel pipe often leads to too large cross-section fillet, which affects the aesthetics of indoor visual surface. With the progress of processing technology, such as hot pressing, fine grinding and welding technology, the steel pipe section has been able to meet the design requirements of the fillet accuracy. Based on practical engineering experience and material properties, this paper deeply discusses the feasibility and advantages of using high-precision steel (refined steel) keel instead of traditional aluminum alloy keel in large-span glass curtain wall.
