Road and bridge steel box girder assembly construction method
The invention discloses a road and bridge steel box girder assembly construction method, which comprises the following steps of: determining the elevation of each longitudinal point of a jig frame according to a designed given line shape, ensuring that a jig frame foundation has enough bearing capacity to avoid steam drop in a use process, and arranging a longitudinal base line, a transverse base line and a reference point on the jig frame to control the position and height of a girder section; according to the method, the elevation of each longitudinal point of the jig frame is determined according to the designed given line shape, the longitudinal base line, the transverse base line and the reference point are arranged on the jig frame so as to control the position and height of the beam section, two movable cross beams need to be reserved in the longitudinal direction of the jig frame, the final assembly period is shortened, and before the top plate unit and the two bottom plate units participate in beam section assembly, two top plate units and two bottom plate units are respectively welded into one hoisting plate block on the special jig frame, so that the time for pre-assembly by moving beams in the road and bridge steel box beam assembly construction is shortened, the manufacturing period is shortened, and the working efficiency of the road and bridge steel box beam assembly construction is improved.
本发明公开了一种路桥钢箱梁拼装施工方法，包括施工方法如下：将胎架纵向各点标高按设计给定的线形确定，胎架基础必须有足够的承载力，确保在使用过程中不发生汽降，在胎架上设置纵、横基线和基准点，以控制梁段的位置及高度，本发明通过将胎架纵向各点标高按设计给定的线形确定，在胎架上设置纵、横基线和基准点，以控制梁段的位置及高度，胎架纵向应预留两个活动横梁，缩短总装周期，在顶板单元和两个底板单元在参与梁段组装前，先在专用胎架上分别将二块顶板单元和两个底板单元拼焊成一个吊装板块，从而使得路桥钢箱梁拼装施工减少移梁进行预拼装的时间，缩短制造周期，增加路桥钢箱梁拼装施工的工作效率。
