Large-span basket type arch frame upside-down construction method
The invention discloses a large-span basket type arch frame upside-down construction method, and belongs to the technical field of building construction. The method comprises the following steps: positioning the position of an arch frame, establishing a space coordinate, integrally dividing the arch frame into five sections, erecting a support frame of a middle arch section, welding a jig frame of the middle arch section, welding the middle arch section, installing the other four sections to be connected with the middle arch section, installing a support, constructing a pull rod, and unloading. The inverted construction method is adopted, the arch frame is divided into five sections to be installed, accurate positioning can be achieved, and the installation accuracy is improved. According to the method, errors generated by high-altitude assembly are reduced, the installation quality is guaranteed, the construction progress is accelerated, and safety accidents are prevented. The method provides reference for future similar engineering, and has important theoretical significance and engineering application value. And meanwhile, by means of the method, the construction technology level of enterprises for the lifting basket arches can be improved, the competitiveness of the enterprises for contracting similar projects is enhanced, and greater later benefits are brought to the enterprises.
本发明公开了一种大跨提篮式拱架倒装施工方法，属于建筑施工技术领域。该方法包括步骤：定位拱架位置建立空间坐标、将拱架整体分为五段、搭设中间拱段的支撑架、焊接中间拱段的胎架、焊接中间拱段，安装其余四段与中间拱段连接、安装支座、拉杆施工，卸载。本发明采用倒装法施工，将拱架分为五段进行安装，能够精确定位，提高了安装精度。本发明方法减少了高空拼装产生的误差，保证了安装质量，加快了施工进度，防止了安全事故的发生。本发明方法为今后类似工程提供了借鉴，具有重要的理论意义及工程应用价值。同时通过本发明方法还能够提高企业对于此类提篮拱的施工技术水平，增强企业承揽类似工程的竞争力，为企业带来更大后期效益。
