后浇带结构及施工

The Structure Design and Construction of Latter Poured Belt

后浇带是一种混凝土刚性接缝,它适用于不宜设置柔性变形缝的结构部位及后期变形趋于稳定的结构部位。主要用于解决高层主体与低层裙房差异沉降,超长建筑、混凝土收缩变形及混凝土温度应力引起的裂缝。采用后浇带必须遵守有关的设计构造及施工规范要求,以简化结构设计、缩短工期、节约投资,取得明显的经济效益。

The latter poured belt is a kind of concrete rigid joint and it adapts to the structure site that soft deformation slot is unsuitable for be set and post-deformation will tend to stabilization. The latter poured belt mainly deals with different settlement between the main high-level building and low-rise podium, and cracks caused by super-long building, concrete shrinkage and deformation, and concrete temperature stress. In order to simplify structure design, shorten the time limit for a project, save investment, take obvious economic benefit, the relevant design construction and construction norms must be obeyed
