后浇带的结构设计及施工

The Structural 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。后浇带的主要作用与建筑结构中常采用的沉降缝、变形缝相同。后浇带按其作用可分为沉降后浇带和伸缩后浇带两种 ,后浇带在设计及施工过程中 ,常又分为平直缝和阶梯缝。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 。

The latter poured belt is a kind of concrete rigid junctrure, it serves the structure that unsuitable setting soft deformation slot and anaphase deformation tend to stabilization. The latter poured belt has the same function as subside slot that always using in architecture structure. It can be divided into subside belt and flex belt. It always be divided into straight slot and ladder slot according to it′s function in the process of design and construct. In order to simplify structure design, short the time limit for a project, economize investment,take obvious economy benefit, the relevant design fabricate and construction criterion must be obeyed.
