Segmented traction sliding splicing construction method for wide steel box girder
The invention provides a segmented traction sliding splicing construction method for a wide steel box girder, which adopts the principle that a splicing and sliding bracket is erected in a specified construction area, the wide steel box girder is divided into a plurality of segments, and each segment is divided into a plurality of components such as a longitudinal beam, a cross beam and a bridge deck system; segmental parts are hoisted to the splicing area of the splicing and sliding support, and all the parts are assembled according to a certain principle to form segments. The first section and the second section are pre-spliced in the splicing area, and then the traction device is installed on the first section, so that the first section slides to a designated position along a sliding way on the sliding support. And the subsequent sections are constructed according to the method in the process of pre-splicing, traction and in-place sliding until all the sections of the steel box girder are constructed and installed. Large mechanical equipment is not needed, the construction device is simple, accurate positioning and splicing of the steel box girder can be achieved, and the method has the advantages of being convenient to construct, capable of being repeatedly used, high in labor efficiency and the like.
本发明提供一种宽幅钢箱梁分段牵引滑移拼接施工方法，原理是在施工规定区域内搭设拼接和滑移支架，将宽幅钢箱梁分为若干节段，每个节段划分为纵梁、横梁和桥面系若干部件，将节段部件吊装到拼接和滑移支架的拼接区域按照一定原则组装各部件形成节段。第一节段和第二节段在拼接区域预拼接，然后将牵引装置安装到第一节段上，使第一节段沿着滑移支架上的滑道滑行到指定位置。后继节段依此方法按照预拼接‑牵引‑滑移到位的过程进行施工，直至钢箱梁所有节段施工安装完毕。本发明不要大型机械设备，施工装置简单，可实现钢箱梁精确定位拼接，具有施工便利，可重复性利用，劳动效率高等优点。
