Method for integrally prefabricating and hoisting plate-type pier body reinforcing steel bars
The invention discloses a method for integrally prefabricating and hoisting plate-type pier body steel bars, which comprises the following steps of: prefabricating a steel bar cage, and accurately positioning main bars of the steel bar cage by using a jig frame; auxiliary steel bars are arranged according to a design drawing, and pre-butt joint is conducted on adjacent steel reinforcement cages so as to guarantee accurate butt joint of sleeves during hoisting; transferring the reinforcement cage to a construction site; a crawler crane and a special hanging bracket are adopted for hoisting the reinforcement cage, the reinforcement cage is commanded to be hoisted to the butt joint position, after the reinforcement cage is adjusted to be horizontal, sleeves at the four corners of the reinforcement cage are pre-tightened, and then multiple persons tighten remaining bolts at the same time; binding stirrups and cushion blocks in the butt joint area, and binding the rest stirrups and cushion blocks according to a drawing. The positioning jig frame is used for positioning the main reinforcements and the stirrups, the overall accuracy of the reinforcements is guaranteed, the reinforcements are prefabricated in sections in advance in a reinforcement factory and are transported to a construction site and then overall hoisting is conducted through a crawler crane and a special hanging bracket, the time of the whole process is only 0.5 workday, and the purposes of rapid construction and reduction of potential safety hazards are achieved.
本发明公开了一种板式墩身钢筋整体预制吊装的方法，预制钢筋笼，利用胎架对钢筋笼的主筋进行精准定位；按设计图纸设置辅助钢筋，对邻节钢筋笼进行预对接以保证吊装时套筒精准对接；转运钢筋笼至施工现场；采用履带吊、专用吊架进行吊装钢筋笼，指挥吊至对接位置，调至水平后，先将钢筋笼四角的套筒进行预紧，然后多人同时对剩余螺栓进行打紧；对接区域箍筋、垫块绑扎，按图纸绑扎剩余箍筋、垫块。利用定位胎架定位主筋与箍筋，保证了钢筋的整体精准度，钢筋厂提前对钢筋分节预制，转运至施工现场后使用履带吊与专用吊架进行整体吊装，整个工序时间仅需0.5个工作日，达成快速施工、减少安全隐患的目的。
