摘要
江胜大厦裙楼屋面1000mm×2500mm大梁应用了型钢混凝土结合结构技术,其跨度30m,梁内配H型钢,每根型钢梁重达23t,安装高度20.45m,采取了一次吊装一次浇筑的施工措施。工程主体施工结束后,型钢结合大梁表面未发现有害裂缝,安全性能和使用功能得到保证,取得了良好的社会效益。
Formed steel concrete composite structure techniques are adopted in construction of 1 000mm× 2 500 mm main beam on roof of podium of Jiangsheng Building. H steel, each piece of which is as heavy as 23 t, is used in the 30m-span main beam, and its installation height is 20.45 m. One-off hoisting and pouring are adopted during the construction. After construction of the main body, no detrimental crack is found on the surface of formed steel composite main beam, safety performance and service functions are guaranteed and favorable social benefits have been realized.
