Large cantilever bent cap component construction method
The invention belongs to the technical field of capping beam construction, and particularly relates to a large cantilever capping beam component construction method, which comprises the following steps of: mounting a profile steel positioning bent frame by matching with a mounting component, carrying out a bracket pre-pressing test on an auxiliary pier part, checking the bracket strength, and timely mounting a profile steel connecting rod after the mounting is completed. The matched installation component comprises a holding mechanism arranged on the outer surface of the upper end of the steel pipe stand column, a lifting supporting mechanism is arranged on the lower surface of the holding mechanism, and a radial moving mechanism is arranged on the lower surface of the lifting mechanism. According to the large cantilever bent cap component construction method, the pushing air cylinders at the two ends act, the piston rods of the pushing air cylinders push the pushing rods and the elastic extrusion pads, and when the pushing rods move forwards, the abutting rods and the elastic extrusion pads can make the holding hoops contract and clamp the holding hoops at the same time; therefore, the profile steel positioning bent frame and the distribution beam for building the supporting platform can be fixedly installed on the outer surface of the upper end of the steel pipe stand column, and then the enclasping mechanism can be conveniently disassembled in the later period.
本发明属于盖梁施工技术领域，尤其是一种大悬臂盖梁部品化施工方法，通过配合安装部件安装型钢定位排架，对辅助墩部分进行支架预压试验，检验支架强度，安装完成后，及时安装型钢联系杆，所述配合安装部件包括设置在所述钢管立柱上端外表面的抱紧机构，所述抱紧机构的下表面设置有升降支撑机构，所述升降机构的下表面设置有径向移动机构。该大悬臂盖梁部品化施工方法，通过两端的推动气缸进行动作，使其活塞杆对推动杆及弹性挤压垫进行推动，则通过推动杆向前运动时可使抵杆和弹性挤压垫同时使抱紧箍收缩夹紧，从而可使搭建支撑平台的型钢定位排架和分配梁固定安装在钢管立柱的上端外表面，进而可便于后期对抱紧机构进行拆卸。
