Hoisting method for main truss of steel truss girder
The invention provides a hoisting method for a main truss of a steel truss girder. The hoisting method comprises the steps that the main truss of each section of the steel truss girder is designed and divided into a lower half truss piece and an upper half truss piece; the lower half truss piece and the upper half truss piece are horizontally transported to a construction site after being manufactured in a factory; a gantry crane is used for hoisting on site, and a main hook and an auxiliary hook are arranged on the gantry crane; during hoisting, a main hook and an auxiliary hook of the gantry crane are matched, the lower half truss piece and the upper half truss piece are turned over by 90 degrees from the horizontal state to the vertical state, and then the lower half truss piece and the upper half truss piece are hoisted to a support; and the lower half truss piece and the upper half truss piece are connected into a whole truss piece on the support through high-strength bolts. According to the invention, the quantity of on-site hoisting and connection of rod pieces can be reduced, the hoisting efficiency is improved, and the mechanical and labor costs are saved.
本发明提供一种钢桁梁主桁架吊装方法，包括将钢桁梁每个节段的主桁架设计分割为下半桁片和上半桁片；所述下半桁片和上半桁片在工厂内制造完成后，水平运输至工地现场；现场利用一台龙门吊进行吊装，所述龙门吊上设置有主钩和副钩；吊装时，利用所述龙门吊的主钩、副钩配合，分别将所述下半桁片和上半桁片从水平状态翻转90°至竖直状态，再吊装至支架上；在支架上将所述下半桁片和上半桁片通过高强螺栓连接成一个整桁片等步骤。本发明能够减少杆件现场吊装和连接的数量，提升吊装效率，节约机械和劳动力成本。
