要准确控制柱纵向钢筋的位置,除常规的施工方法外,还需制作控制柱纵向钢筋的水平内撑。它的制作方法很简单,应根据柱截面的大进行设计,材料采用与柱箍筋直径相同的钢筋。内支撑的设置间距1.5～2米比较适宜。内支撑的制作,最好采用点焊,它牢固不变形,见图1。钢筋混凝土柱采用内支撑法施工,保证了柱纵向钢筋的设计位置,不倾斜不移动。经混凝土 To accurately control the position of the column longitudinal reinforcement, in addition to the conventional construction methods, horizontal support of the longitudinal reinforcement of the control column is also required. Its production method is very simple, and it should be designed according to the large section of the column. The material is the same as the steel bar stirrups. The spacing of the inner support is 1.5 to 2 meters. It is best to use spot welding for the production of the internal support. It is firmly deformed, see Figure 1. The reinforced concrete column is constructed by the internal support method, which ensures the design position of the column longitudinal reinforcement and does not move without tilting. Concrete
