All-welded steel box truss girder upper chord member and web member positioning device and construction method
The invention discloses an all-welded steel box truss girder upper chord and web member positioning device which comprises an upper chord and two web members fixed to the lower side of the upper chord. An auxiliary positioning device is fixedly arranged between the two web members; the auxiliary positioning device comprises a connecting plate and positioning channel steel; a connecting plate is fixedly arranged on each web member; and the positioning channel steel is fixedly connected between the two web members through the connecting plate. According to the positioning device, when the steel truss girder is pre-spliced, the connecting plates, the positioning channel steel and the connecting bolts are manufactured in a matched mode at the same time, and accuracy is high; the positioning channel steel is uniform in length, field installation operation is simple and convenient, and operation of workers is facilitated; the connecting device is detachable, is connected with the web members through the connecting bolts and the connecting plates, and is convenient to operate, novel in structure and capable of being repeatedly used. Adjusting construction of the positioning device is fast and simple, adjusting precision is improved, the line shape of the steel box girder is guaranteed, and a theoretical basis is provided for follow-up construction of bridges of the same type. And labor, materials and machine use cost are saved.
本发明公开了一种全焊接钢箱桁梁上弦杆与腹杆定位装置，包括上弦杆以及固定于上弦杆下侧的2个腹杆；2个腹杆之间固定设置有辅助定位装置；辅助定位装置包括连接板和定位槽钢；每个腹杆上均固定设置有连接板；定位槽钢通过连接板固定连接于2个腹杆之间。本发明该定位装置在钢桁梁预拼时，连接板、定位槽钢及连接螺栓同时匹配制作，精确度高；定位槽钢均为统一长度，现场安装操作简单方便，方便工人操作；设置为可拆卸式，通过连接螺栓、连接板与腹杆连接，操作方便，结构新颖，可以重复使用；定位装置的调整施工快速简捷，提高了调整的精度，保证钢箱梁的线形，为后续同类型桥梁施工提供了理论依据；节省人工、材料、机具使用成本。
