通过框架柱上预留抗剪钢筋（或植筋）及环梁与柱之间的摩擦力承受结构荷载。即在增设楼板的梁高范围内增设环梁柱箍节点，其截面尺寸与配筋经设计计算后确定，柱箍的高度宜与新增主梁的高度一致。新增主梁钢筋锚入环梁柱箍内，柱箍的钢筋、模板制安，混凝土浇筑与新增的梁板结构同步施工，达到结构受力要求。%The friction force between reserved shear reinforcement (or embedded steel bar) with ring beam and the column withstands the structural load. That is to say, to add nodes of ring beam column hoop within the height scope of beam on the added floor slab, the section size and reinforcement of the nodes are determined after design and calculation, and the height of column hoop should be the same with that of newly added main beam. The main beam reinforcement should be anchored to ring beam column hoop, and the establishment of column hoop and template, the pouring of concrete and the construction of newly added beam structure should be carried out at the same time to meet the requirement of structure stress.
