Longitudinal sliding and vertical lifting construction method for main truss of large-tonnage cable-stayed hanging basket
The invention discloses a longitudinal sliding and vertical lifting construction method for a main truss of a large-tonnage cable-stayed hanging basket. According to the construction method, a front fulcrum hanging basket is assembled by utilizing the rigidity of a cross beam to bear the dead weight, and an assembling platform is only arranged at the position of a main longitudinal beam. By reasonably reducing the number of assembling platforms, construction materials can be effectively saved, and the construction cost is saved. According to the construction method, three pieces of round steel are longitudinally arranged on a longitudinal beam assembling platform of the front fulcrum hanging basket, grease is evenly smeared on the surface to serve as a sliding rail, and a jack is arranged on the sliding rail to push a sliding counter-force support. The hanging basket, the jack pushing sliding system and the support assembling platform form a whole, the support does not have external horizontal force in the sliding process of the hanging basket, and it is guaranteed that the hanging basket slides in place safely and stably.
本发明公开了一种大吨位牵索挂篮主桁架纵向滑移竖向提升施工方法，本工法前支点挂篮拼装通过利用横梁自身刚度承载自重，仅在主纵梁位置设置拼装平台。通过合理的减少拼装平台，能有效的节约了施工材料，节省施工成本；本工法前支点挂篮在纵梁拼装平台上纵向设置三根圆钢，表面均匀涂抹油脂作为滑移轨道，并在滑移轨道上设置千斤顶顶推滑移反力支座。挂篮、千斤顶顶推滑移系统及支架拼装平台成为一个整体，挂篮滑移过程中支架无外界水平力，保证了挂篮安全平稳的滑移就位。
