上海华东纺织工学院分院实验楼工程,长75.8米,进深为16.7米,建筑物总高25.25米,纵向三列柱,柱子断面为400×400毫米,总面积为7117平方米,六层框架结构。一、长柱无牛腿节点的改进方案本工程原采用长柱无牛腿装配式构造方案。该方案中节点是由柱内主筋、加强竖向钢筋、附加的交叉斜筋和水平撑筋构成(图一)。这种柔性钢筋组成节点的封头模板不仅配置复杂,而且模板拆下无法重复利用,同时现场钢筋电焊的工作量大,园钢筋之间的焊接质量也较难保证。根据我们施工劲性
Shanghai East China Textile Engineering Institute Branch Experimental Building Project, 75.8 meters long, 16.7 meters deep, 25.25 meters high building, vertical columns of three columns, pillar section of 400 × 400 mm, a total area of 7117 square meters, six-story frame structure . First, the long column no cow legs node improvement program This project originally used long column no cow leg assembly type construction scheme. The node in this program is composed of main bars in the column, reinforced vertical bars, additional crossed diagonal bars and horizontal bars (figure 1). The header template of the node of the flexible steel bar is not only complicated in configuration, but also can not be reused when the template is removed. At the same time, the workload of on-site rebar welding is large, and the welding quality between the steel bars of the garden is also difficult to guarantee. According to our construction
