大跨度钢横梁及拉杆式幕墙施工技术

CONSTRUCTION TECHNOLOGY OF LARGE SPAN STEEL CROSS BEAM AND TIE ROD CURTAIN WALL

为解决大跨度幕墙结构受力体系问题,达到建筑立面的最优效果,通过水平钢横梁与竖向拉杆式结构结合应用的施工技术实际案例分析,研究了二者结合使用施工的可行性。结果表明:二者结合使用可取长补短,既能避免钢梁截面过大又能控制拉杆稳定。可见这种结合的施工方法有利于幕墙的受力体系,该施工技术极大程度体现幕墙系统大跨度玻璃幕墙立面无竖向龙骨的效果,保证了施工的安全。

For the purpose of solving the problem of large-span curtain wall structure stress system and achieve the optimal effect of building facade,this paper studies the feasibility of the combination of horizontal steel beam and vertical pull rod structure through the actual case analysis of construction technology.The results show that the combination of the two can learn from each other's strengths,which can not only avoid the excessive cross section of steel beam,but also control the stability of pull rod.This combined construction method is beneficial to the stress system of curtain wall and this construction technology greatly reflects the effect that the facade of large-span glass curtain wall of curtain wall system has no vertical keel,which ensures the safety of construction.
