The invention discloses a large steel structure beam hoisting and positioning lifting lug and a hoisting method, the designed lifting lug is adopted to meet the requirements of hoisting, temporary fixing and positioning operation, so that the steel structure beam hoisting operation is quicker, the positioning is more accurate, and long-term occupation of a tower crane is avoided. In the hoisting process of the steel structure beam, under the cooperation of one hoisting device (such as a tower crane), the waiting time for occupying the tower crane can be shortened through designed lifting lug hoisting and fixing of the lifting lug on the bracket of the steel structure column, so that the continuous hoisting operation and rapid mounting and positioning of the steel structure beam can be realized, the waiting time of the tower crane is greatly shortened, and the hoisting efficiency is improved. And the operation efficiency of the steel structure beam is improved. By the adoption of the technical scheme, the lifting lug component is designed and adopted, the lifting lug component is made of steel, and according to the quality of the steel structure beam, steel plates which can be Q345, Q355, Q235 and the like are selected and mainly adopted to be welded to the two ends of the steel structure beam.
本发明公开了一种大型钢结构梁吊装定位吊耳及吊装方法,通过采用设计的吊耳可以实现吊装、临时固定、定位作业要求,使得钢结构梁吊装作业更快速,更高精准定位,避免了长期占用塔吊。在钢结构梁吊装过程中,在一台吊装设备(比如塔吊)配合下,可通过设计的吊耳吊装和吊耳在钢结构柱牛腿的上的固定,缩短占用塔吊的等待时间,即可实现钢结构梁的吊装连续作业和快速安装定位,从而大大缩小塔吊等待时间,提高了钢结构梁作业效率。通过采用上述技术方案,设计采用的吊耳构件,其材质为钢材,根据钢结构梁质量,选择主要采用的类型可为Q345、Q355、Q235等型号的钢板进行焊接在钢结构梁两端。
