目前,随着社会经济的发展,城市中超长结构,大底盘多塔式结构或形体不规则结构的建筑不断涌现。特别是对地下防水有特殊要求的超大面积地下建筑的不断出现。后浇带是一种混凝土刚性接缝,它主要于不宜设置柔性变形缝的结构部位以及后期变形趋于稳定的结构部位。后浇带的主要应用于解决高层主体与低层裙房差异的沉降、超长建筑、混凝土收缩变形及混凝土温度应力引起的裂缝,可以简化结构设计,缩短工期,节约投资,加快施工进度,取得明显的经济效益。
At present, with the development of society and economy, the construction of super long structure, big chassis multi-tower structure or irregular body structure in cities emerges. Especially for underground water there are special requirements for super large area of underground buildings continue to emerge. Post-pouring belt is a rigid concrete joints, which is mainly not suitable for the installation of flexible deformation of the structural part of the deformation and post-deformation tends to be stable structural parts. After the pouring zone is mainly used to solve the difference between the high-rise main body and the lower podium of settlement, long construction, concrete shrinkage deformation and concrete temperature stress cracks can simplify the structural design, shorten the construction period, save investment, speed up the construction progress, and achieved significant The economic benefits.
