【 摘 要 】

The lifting of precast elements is an important process in precast concrete structure construction, which directly concerns the quality of the building products and the subsequent use of precast elements. Based on the construction codes at home and abroad and some former researches, this paper discusses the construction load value, calculation model and checking calculation contents of shear panel during lifting. Taking the lifting of a high-rise building precast shear panel as the engineering background, combined theoretical analysis with numerical calculation, this paper determines the construction load of the precast shear panel during lifting, checks the maximum tensile stress of concrete, reinforcement stress at the tension section and bending capacity of the section, contracts the lifting design of the two-point lifting and the three-point lifting. Therefore, the conclusion that the two-point lifting is more economical under the premise of ensuring the safety of the lifting point is obtained, and the checking and verification problem of the precast shear panel during lifting is solved.
