现场施工,常遇到侧面为梯形的钢筋混凝土构件,如双坡、单坡屋面梁,悬臂梁,牛腿柱等,箍筋的高度各不相同,下料的难度较大。现介绍一种箍筋下料长度图解法。例如,有一钢筋混凝土悬臂梁,各部分尺寸见图1。纵筋保护层厚度为20毫米,箍筋为φ6@100。其 On-site construction often encounters trapezoidal reinforced concrete members, such as double slopes, single-pitch roof beams, cantilever beams, bovine legs, etc. The height of the stirrups is not the same, and the difficulty in material removal is large. A graphical method for the length of stirrup blanks is introduced. For example, there is a reinforced concrete cantilever beam, the size of each part is shown in Figure 1. The thickness of the protective layer of longitudinal reinforcement is 20 mm, and the stirrup is φ6@100. its
