Design and Mounting of the Internal Tube Model in the Concrete Hollow Floor Construction

基于强度、刚度优化原理,确定空心管的最佳固定位置,再设计三维锁定式空心管的固定体系,通过马凳筋、钢筋阻隔格与上、下板钢筋网连接,形成一个抗浮体系,最后结合其它施工过程,介绍了相关质量控制措施。施工效果表明该技术方法科解决空心管在施工过程中漂浮移位、偏斜等问题,有效保证了整个楼板板面、板底的平整度、结构性能和工程整体施工质量。

Based the strengthens and stiffness optimization principle,the best fixed position of the hollow tube was determined. Then 3D fixing system was designed for the hollow tube. An anti-floating system was combined with the supporting rib,the limiting band,the upper and lower reinforcing mat and the formwork supports. Finally,in combination with other construction process,some quality control measures to the construction of the concrete hollow floor were introduced. The construction effect shows that the method to solve the problems of settlement,shifting and deflection of tube in the construction process is effective to ensure the whole construction quality of the hollow floor plate.
