Steel-concrete composite beam cantilever lifting appliance and safety protection method
The invention relates to a steel-concrete composite beam cantilever lifting appliance which comprises a right triangle cantilever support, channel steel is installed on the two right-angle sides of the right triangle cantilever support in a back-to-back mode, and gaps are formed between the channel steel and the corresponding right-angle sides so that bolt lifting rods can penetrate through the gaps conveniently. The technical problems that a steel-concrete composite beam is large in height, and open passage is needed below are solved; a problem of adjusting cross slopes of roads on the left and right sides of a bridge is solved; The structure is simple, and operation is convenient, The appliance is safe, reliable and highly practical; repeated use is realized, and use cost is reduced. Inaddition, the invention further provides a safety protection method.
本发明涉及一种钢混组合梁悬臂吊具，包括直角三角形悬臂支架，所述直角三角形悬臂支架的两直角边背靠背安装有槽钢，槽钢与对应的所述直角边之间设有间隙，以便螺栓吊杆穿过。解决钢混组合梁高度大、下方需开放通行的技术问题。解决桥梁左、右两侧道路横坡调整问题。结构简单，操作方便。安全可靠，实用性强。可重复使用，降低使用成本。此外，本申请还提供了一种安全防护方法。
