Method for processing, manufacturing and constructing prefabricated small box girder hanging bracket
The invention relates to a method for processing, manufacturing and constructing a prefabricated small box girder hanging bracket, which comprises a small box girder hanging bracket structure design and processing and manufacturing method: the small box girder hanging bracket structure is formed by forming a group by two hanging brackets, each hanging bracket is provided with eight waist-shaped hoisting holes, and eight preformed holes are reserved in corresponding positions of a small box girder; the hanging bracket is connected with the small box girder through a high-strength hanging rod/finish rolling deformed steel bar; two lifting lugs are arranged on each lifting frame and are connected through lifting pin rods, and lifting operation can be carried out through shackles and lifting equipment; a small box girder mounting and small box girder hanging bracket using method comprises the steps that small box girders are transferred and loaded in a prefabricated part factory through the small box girder hanging bracket; the small box girder is hoisted and installed on the top of the bent cap through the small box girder hoisting frame after being transported to an installation site, and the small box girder hoisting frame is dismantled after the small box girder is hoisted. The problems that the small box girder is difficult to install in a complex environment and the small box girder structure is uneven in stress under a special hoisting working condition are solved; and by using the small box girder hanging bracket, the construction safety is greatly improved, and the construction cost is saved.
本发明涉及一种预制小箱梁吊架加工制作及施工方法，包括小箱梁吊架结构设计及加工制作方法：小箱梁吊架结构由两个吊架组成一组，每个吊架上设置8个腰型吊装孔，小箱梁相对应位置预留8个预留孔，吊架与小箱梁通过高强吊杆/精轧螺纹钢进行连接；每个吊架上设置2个起重吊耳，采用吊装销棒连接，能够通过卸扣与起重设备进行吊装作业；小箱梁安装及小箱梁吊架使用方法：小箱梁在预制构件厂通过小箱梁吊架转场装车；小箱梁运输至安装现场后通过小箱梁吊架起吊安装在盖梁顶上，小箱梁吊装完成后拆除小箱梁吊架。本发明解决了复杂环境下小箱梁难以安装、特殊起吊工况下小箱梁结构受力不均等；小箱梁吊架的使用大大提高了施工安全性和节约了施工成本。
