大底盘地下室后浇带设置和施工的应用

Application of Late Poured Band Device and Construction to Large Chassis Basement

文章针对后浇带在大底盘地下室的通用做法,介绍了施工后浇带的形式和相关规范规定,后浇带技术有效控制混凝土硬化形成的裂缝、解决主楼与裙房间之间的沉降差,保证结构整体性。对后浇带无缝设计技术的设计方法和施工工艺进行了探讨,并结合实际工程,介绍了现浇后浇带对于大底盘地下室的应用。

According to the general practices on the late poured band in the large chassis basement, the paper introduced the construction form of the late poured band and the related standard and regulations. The late poured band technology could effectively control the cracks occurred by the hardening of concrete and could solve the settlement difference between the main building and podium in order to ensure the structure integration. The paper had a discussion on the design method and construction technique of the late poured band seamless design technology. In combination with the actual engineering project, the paper introduced the application of the site pouring late poured band to the large chassis basement.
