钢筋混凝土结构后浇带是通过施工过程中的有效措施来解决建筑结构预控沉降、伸缩或温差的调整办法,达到不设永久变形缝的目的。其机理就是以设置临时性变形带的方法释放大部分约束应力,然后用强度较高的补偿收缩混凝土填后浇带以抗衡残余应力。本文简要介绍了地下室后浇带的合理设计及施工技术,要点。对问题进行了分析,以保证后浇带的施工质量。
The post-pouring zone of reinforced concrete structure is to solve the precontrol settlement, expansion or temperature adjustment of the building structure through effective measures in the construction process, so as to achieve the purpose of no permanent deformation seam. The mechanism is to set the temporary deformation zone method to release most of the restraint stress, and then use a higher strength compensation shrinkage concrete filled with pouring tape to counter the residual stress. This article briefly introduces the basement pouring zone of the rational design and construction techniques, points. The problems were analyzed to ensure the construction quality of post-pouring belt.
