Accurate positioning auxiliary device for mounting H-shaped steel girder
The invention discloses an accurate positioning auxiliary device for H-shaped steel girder installation. The longitudinal positioning steel plate is welded on the U-shaped clamping plate base by adopting a double-sided welding seam; the transverse stiffening steel plate, the U-shaped clamping plate base and the longitudinal positioning steel plate are connected into a whole, and it is guaranteed that stress of the longitudinal positioning steel plate is stable. The U-shaped clamping plate base is clamped into an upper flange steel plate of the steel cover beam, bolt holes are formed in the U-shaped clamping plate base, and fixing bolts penetrate through the bolt holes to fix the U-shaped clamping plate base. The device is mounted on the upper flange of the steel box when the steel-concrete combined cover beam steel box is machined, the position precision of the mounting plane of the H-shaped steel girder is adjusted and controlled to the millimeter level, and the problems of low efficiency, poor precision and high safety risk due to the fact that the H-shaped steel girder falling position is determined by staff through line marking and observation in the girder profile steel hoisting and mounting process are avoided. Secondary adjustment consumes manpower and material resources, and the manufacturing cost is high.
本发明公开了一种H型钢主梁安装精准定位辅助装置；纵向定位钢板采用双面焊缝焊接在U型卡板底座上；所述横向加劲钢板与U型卡板底座和纵向定位钢板连接成一个整体，保证纵向定位钢板的受力稳定；U型卡板底座将其卡进钢盖梁的上翼缘钢板上，U型卡板底座上开设螺栓孔，穿过固定螺栓用于固定该U型卡板底座。此装置在钢混组合盖梁钢箱加工时安装到钢箱上翼缘上，将H型钢主梁安装平面位置精度调整控制到毫米级，避免了主梁型钢吊装安装过程中，利用划线标识，人员通过观察确定H型钢主梁落梁位置，效率低、精度差、安全风险高，二次调整耗费人力、物力，造价高等问题。
