Steel box girder segment splicing connection structure and construction method thereof
The invention relates to a steel box girder segment splicing and connecting structure and a construction method thereof. The steel box girder segment splicing and connecting structure comprises steel box girder segments and embedded corrugated plates. Transverse stiffening ribs, longitudinal stiffening ribs which penetrate through the transverse stiffening ribs and are vertically arranged and longitudinal inserting grooves which are used in cooperation with the embedded corrugated plates are welded to top plates and bottom plates of the steel box girder sections, and the embedded corrugated plates are installed in the longitudinal inserting grooves in the adjacent steel box girder sections. According to the steel box girder segment splicing and connecting structure, the embedded corrugated plates are inserted into the longitudinal inserting grooves of the adjacent steel box girder segments to achieve pre-splicing of the steel box girder segments before girth welding, and the connecting structure can help the steel box girder segments to keep no relative displacement in the further welding process; after the steel box girder is hoisted, a splicing line shape is achieved, and girth welding construction between girder sections is facilitated; and rapid pre-assembly of the segments in a non-welding mode is achieved, the segments do not need to be dismantled after ring welding, and the segments can serve as permanent stiffening ribs of the steel box girder.
本发明涉及一种钢箱梁节段拼装连接构造及其施工方法，该钢箱梁节段拼装连接构造包括钢箱梁节段和嵌入波形板；所述的钢箱梁节段的顶板和底板上焊接有横向加劲肋、穿过横向加劲肋垂直设置的纵向加劲肋以及与嵌入波形板配套使用的纵向插槽，所述的嵌入波形板安装在相邻钢箱梁节段上的纵向插槽中。本发明钢箱梁节段拼装连接构造通过将嵌入波形板插入相邻钢箱梁节段的纵向插槽中实现钢箱梁节段环焊之前的预拼装，该连接构造可帮助钢箱梁节段在进一步的焊接过程中保持节段间不发生相对位移，钢箱梁吊装完成后即达到拼装线形，便于梁段间的环焊施工；实现了无焊接形式的节段快速预拼装，在节段环焊后无需拆除，可以作为钢箱梁的永久加劲肋。
