Total splicing jig frame and steel box girder splicing method thereof
The invention discloses an overall assembly jig frame and a steel box girder assembly method thereof, and belongs to the technical field of bridge construction, the overall assembly jig frame comprises a jig frame track, movable jig frames with adjustable intervals are arranged on the jig frame track, the movable jig frames are in one-to-one correspondence with all sections of a steel box girder, and bearing faces matched with bottom plates of the sections in shape are arranged on the movable jig frames. The bearing face is provided with a locking area used for being fixed to the segment. The assembling method comprises the steps that S1, the general assembling jig frame is erected; s2, steel box girder sections are assembled; s3, the box opening matching degree is detected; s4, drill hole groups are matched for the segments, permanent lug plates are welded, and temporary matching pieces are installed; and S5, each section is subjected to tire release, and the section at the tail end is moved to the movable tire frame at the head end to serve as a mother beam for total splicing of the next round. According to the construction condition, the steel beam sections move front and back along with the movable jig frame, the requirement for overall splicing section matching can be met at small intervals, the requirement for construction convenience can be met at large intervals, only the placing position of the steel beam is changed when the jig frame track moves, the overall splicing linetype is not changed, and the splicing precision is guaranteed.
本发明公开了一种总拼胎架及其钢箱梁拼装方法，属于桥梁施工技术领域，总拼胎架包括胎架轨道，胎架轨道上设有间距可调的移动胎架，移动胎架与钢箱梁各节段一一对应，移动胎架上设有与节段的底板形状相匹配的承托面，承托面上设有用于与节段固定的锁定区。拼装方法包括：S1、搭设总拼胎架；S2、拼装钢箱梁节段；S3、检测箱口匹配度；S4、为节段配钻孔群，焊接永久耳板，安装临时匹配件等；S5、各节段进行脱胎，将尾端的节段移至首端移动胎架上，作为后一轮次总拼的母梁。根据施工状况将钢梁节段随移动胎架前后移动，既能小间距满足总拼截面匹配，又能大间距满足施工便利，且胎架轨道移动仅改变钢梁摆放位置，整体拼装线型不变，保证了拼装精度。
