本文运用建筑力学的知识分别用两组控制条件对预制钢筋混凝土细长柱的起吊点位置进行了设计,并用实例对这两组起吊点位置进行了抗弯强度和抗裂度的验算,确立了合理起吊点位置.结果表明:按第一组力学控制条件求得的起吊点位置安全储备高,满足工程实际的要求. In this paper, using the knowledge of building mechanics, two groups of control conditions are respectively used to design the lifting points of the precast reinforced concrete slender columns. The bending strength and crack resistance of the two groups of lifting points are verified by examples. Reasonable lifting point position.The results show that: according to the first set of mechanical control conditions, the safe storage place of the lifting point is high, which meets the actual engineering requirements.
