The invention belongs to the field of structure construction, and particularly discloses a truss-suspension structure upside-down accumulated hydraulic lifting construction method based on a preassembled structure, which comprises the following specific steps: S1, construction preparation; s2, the roof truss structure is assembled on the ground; s3, temporary measures of the lifting system are installed; s4, a lifting system is installed and debugged; s5, trying to lift by the first lifting unit; s6, the first lifting unit performs formal lifting; s7, a temporary support of the lifting unit is installed; s8, a suspension structure of the next layer of the truss is installed; s9, trying to lift by the second lifting unit; s10, the second lifting unit performs formal lifting; s11, mounting a secondary second-layer suspension structure of the truss; s12, trying to lift by a third lifting unit; s13, formally lifting by a third lifting unit; s14, the temporary facilities are dismantled after installation is completed; the special lifting steel strands are connected with the corresponding lower lifting points on the lifting steel structure, the lifting height and the lifting amplitude are not limited, supporting structures on the ground are reduced to the maximum extent, and the construction site is saved.
本发明属于结构施工领域,具体公开了基于预装结构的桁架‑悬吊结构倒装法累积液压提升施工方法,具体步骤如下:S1、施工准备;S2、屋面桁架结构地面拼装;S3、提升系统临时措施安装;S4、提升系统安装和调试;S5、第一提升单元试提升;S6、第一提升单元正式提升;S7、安装提升单元临时支撑;S8、桁架次一层悬吊结构安装;S9、第二提升单元试提升;S10、第二提升单元正式提升;S11、桁架次二层悬吊结构安装;S12、第三提升单元试提升;S13、第三提升单元正式提升;S14、安装完成拆除临时设施;本发明通过提升专用钢绞线与提升钢结构上的对应下吊点相连接,提升高度与提升幅度不受限制,最大限度减少地面上的支撑结构,节省施工场地。
