大体积混凝土“跳仓法” 与加强带施工工法大体积混凝土“跳仓法” 与加强带施工工法 摘要:大型超长结构中为控制混凝土温度造成的影响,根据《混凝土结构设计法律规范》GB20010-2025 要求,都必须要在结构底板、楼板及壁墙多处设置后浇带,待大体积混凝土收缩稳定后再浇筑后浇带混凝土,以此来防止由温度引起的收缩性非结构墙体、楼板裂缝
对于施工来说,后浇带增大了施工难度,延长了工程工期,且极易造成一些质量安全等隐患

For the construction, after pouring belt increases the difficulty of construction, extend the period of a project, and easy to cause some quality and safety prob
