组装式回顶装置在地下室后浇带中的应用研究

APPLICATION OF ASSEMBLED TOP RETURN DEVICE IN BASEMENT AFTER POURING BELT

钢柱配合顶托的后浇带回顶装置在普通钢柱回顶装置的基础上做出了优化,不仅保留了钢柱回顶周转率高、施工现场美观、拆除污染小、搭设时间短的优点,而且增加了可以调节高度的顶托,施工时可灵活调整钢柱高度。本装置操作原理简单、安全可靠、可周转使用、成本小,故可大规模使用。

The post pouring back to the top device of the steel column combined with the top support has been optimized on the basis of the ordinary steel column back to the top device.It not only retains the advantages of high turnover rate of steel column back to the top,beautiful construction site,low demolition pollution,and short installation time,but also adds a top support that can adjust the height,and the construction time can flexibly adjust the height of the steel column.The operating principle of this device is simple,safe and reliable,reusable,and costeffective,so it can be used on a large scale.
