21世纪以来,随着高层建筑裙房和超长整体地下室的普遍使用,钢筋混凝土结构中,后浇带被越来越多的使用。很多超长地下室未设置抗震缝,为防止建筑物出现裂缝,导致结构主题开裂,后浇带的设置变得尤为重要。当高层建筑与相连的裙房之间不设置沉降缝的时候,为防止主体与裙房之间的沉降,宜在裙房一层设置沉降后浇带。本文按使用用途将后浇带分为两种,即沉降后浇带和伸缩后浇带。并对两种后浇带的设计和施工中应该注意的事项进行简要的分析。
Since the 21st century, with the widespread use of high-rise podiums and super-long basements, post-pouring belts have been used more and more in reinforced concrete structures. Many long basements are not equipped with anti-seismic joints. In order to prevent cracks in the building, the structural theme is cracked and the setting of the post-pouring belt becomes more and more important. When there is no settlement between the tall building and the connected podium, in order to prevent the settlement between the main body and the podium, a pouring belt should be set up in the podium layer. This article uses the use of post-pouring belt is divided into two, namely, after pouring and pouring tape after pouring. And the two kinds of post-pouring belt design and construction should be noted that a brief analysis.
