摘要
某高速公路桥梁桥墩盖梁采用抱箍法施工,抱箍与桥墩立柱须有足够的摩擦以安全地传递荷载。钢抱箍和橡皎垫通过抱箍螺栓固定,经计算确定了盖梁侧模、底模和娜包箍受力、螺栓参数,保证了盖梁安全施工。
The pier cover beam of an expressway bridge is constructed by the hoop method,and there must be enough friction between the hoop and the pier column to transfer the load safely.The steel hoop and rubber pad are fixed by hoop bolts,and the force and bolt parameters of the side form,bottom form and steel hoop of the cover beam are determined by calculation,which ensures the safe construction of the cover beam.
