江苏省泰州市建筑工程公司在泰州电解化工厂电解车间工程中,采用了兼作吊车梁的钢筋混凝土窗架,窗架横构件长6米,中间有3根竖挺,竖挺上设牛腿,牛腿承托的上窗框(上槛)即为吊车梁(见图1、2、3)。吊车梁的跨度不是6米,而是1.5米,因此吊车梁的截面较小。同时,考虑到窗架的结构作用,从而简化了一些构件,如钢筋混凝 Taizhou Construction Engineering Company of Jiangsu Province used a reinforced concrete window frame that doubled as a crane beam in the electrolysis workshop project of Taizhou Electrolytic Chemical Plant. The cross member of the window frame was 6 meters long, and there were 3 vertical stiffeners in the middle, and a bull leg was set on the vertical stand. The upper window frame (upper jaw) supported by the bovine leg is the crane beam (see Figures 1, 2, and 3). The span of the crane beam is not 6 meters but 1.5 meters, so the cross section of the crane beam is small. At the same time, taking into account the structural role of the window frame, which simplifies some of the components, such as rebar coagulation
