浅析混凝土结构后浇带的设计和施工浅析混凝土结构后浇带的设计和施工 摘要:随着高层建筑向体量大型化和功能结构多样化的方向进展,在建筑工程混凝土结构中设置后浇带是目前常见的一种方法,后浇带可以有效的减少收缩应力,有效地利用后浇带对由于水化热而产生的收缩裂缝进行控制,提高了结构的经济性和安全性。最新的设计法律规范要求对长度长、面积较大带地下室的高层板式结构及独立的地下室建筑物均设置沉降或者伸缩后浇带。本文笔者对后浇带的设计和施工中存在的问题进行了分析 关键词:建筑工程;混凝土结构后浇带;控制裂缝;设计和施工 Abstract: with the high-rise buildings to mass large-scale and functional structure diversification direction, in the construction engineering concrete structure setting post-cast strip is the common a method, post-cast strip can effectively reduce shrinkage stress, effective use of the pouring belt due to hydration heat and produce of contraction crack control, improve the structure of the economy and safety. The latest design specification requirements for long length, area is larger with the basement of the top plate structure and the independent in the basement of the building are setting settlement or expansion post-cast strip. In this paper the author of the pouring belt on the design and construction of the problems in the analysis Keywords: building engineering; Concrete structure post-cast strip, Control the cracks; Design and construction 中图分类号:[TQ178]文献标识码:A 文章编号:2095-2104(2025) 引言 后浇带一般具有多种变形缝的功能,它可以有效的减少收缩应力。施工后浇带是整个建筑整体,包括基础以及上部结构施工过程中预留的预留缝,待主体结构完成以后,把后浇带混凝土浇上,既在整个结构施工中解决了高层主楼与低居裙房的差异沉降,又达到了不设永久变形缝的目的。后浇带是一种混凝土刚性接缝,适用于不宜留置柔性变形的结构部位以及后期变形趋于稳定的结构部位。后浇带不仅直接避开了柔性变形缝的施工繁琐、费用大、不易保证接缝质量等缺点,而且其施工比较...
