一、钢筋类型建筑中采用的钢筋有柔性钢筋和劲性钢筋两大类。1.柔性钢筋指建筑工地上常见到的圆形钢筋(直径小于5毫米的称为钢丝),钢筋分为光面钢筋(图1)和变形钢筋(表面有凹凸纹理),如图2所示的螺纹钢筋。2.劲性钢筋是指型钢(图3),受力较大时偶尔采用。建筑用的钢筋要有较高的强度,较好的塑性且与混凝土要有较好的 First, the type of reinforcement used in the rebar type building consists of two categories of flexible steel bars and stiffened steel bars. 1. Flexible steel bars refer to the round steel bars (diameter less than 5 mm) commonly found on construction sites. The steel bars are divided into smooth steel bars (Figure 1) and deformed steel bars (surfaces with bump texture), as shown in Figure 2. Screw rebar. 2. Reinforced steel refers to shaped steel (Figure 3), which is used occasionally when the stress is high. Building reinforcement should have high strength, good plasticity and better concrete
