摘要
目前诸多公共建筑屋面为营造建筑美感与艺术感,设计师在设计时屋面屋架构造部分采用大悬挑,由于钢筋混凝土结构具有自重大且施工风险系数高,质量不可控,影响设计效果的表达的诸多不足因素,故而下部支撑的设计采用异型劲钢结构以满足设计元素的表达。以上合组织青岛峰会新闻中心项目为例,工程屋面设计为大坡度斜屋面,屋顶结构由16块不同标高、不同坡度的板组成,每块板有三个坡度,建筑的四个角中有三个角为大悬挑端,最小悬挑高度8m,最大约20m,下部采用异形悬挑形式的劲钢结构作为支撑体系。该项目施工过程中,将BIM技术纳入基本管理中,并使之成为基层工作的有力支持工具,进行统一规划,进而分布实施,总结形成成熟的施工经验,为有涉及屋面大悬挑钢结构与混凝土结合的项目施工时,提供可行性的解决方案。
At present,in order to create a sense of architectural beauty and art on the roofs of many public buildings,designers use large overhangs in the roof truss structure when designing.Due to the shortcomings of reinforced concrete structures,such as heavy weight,high construction risk factor,and uncontrollable quality,it affects the design effect.The design of the lower support adopts a special-shaped steel structure,which can meet the expression of design elements.Take the SCO Qingdao Summit News Center project as an example.The roof of the project is designed as a large-slope sloping roof.The roof structure consists of 16 slabs with different elevations and slopes,and each slab has three slopes.Three of the four corners of the building are large cantilever ends,with a minimum cantilever height of 8m and a maximum of about 20m.The lower part adopts steel structure in the form of special-shaped cantilever as the support system.During the construction of this project,BIM technology was incorporated into the basic management,and made it a powerful support tool for grass-roots work,summarizing and forming mature construction experience.Provide a feasible solution for the construction of projects involving the combination of large cantilevered steel structure and concrete on the roof.
