Liftable construction platform suitable for beam-arch combined structure
The invention discloses a liftable construction platform suitable for a beam-arch combined structure. The liftable construction platform comprises an upper truss, a lower platform, a driving mechanism and electric chain blocks. The two ends of the upper truss are connected with the lower platform through the electric chain blocks. The upper truss comprises a left truss body and a right truss body, the left truss body and the right truss body are connected through a flange, the left truss body and the right truss body are each formed by assembling a plurality of square pipes, the two ends of the upper truss body are each provided with two upper lifting lugs in a welded mode, the electric chain blocks are installed through U-shaped clamps, and the two sides of the upper truss body are each provided with at least one set of limiting wheels. The safety risk of high-altitude operation can be effectively reduced, and the liftable construction platform is suitable for operation at unequal-height positions in an arch string area. By innovatively designing the application of the construction platform, the high-altitude operation of the bottom of the steel structure bridge is effectively solved, the field construction efficiency is improved, the construction cost is reduced, the construction safety and quality are ensured, and the construction platform has demonstration significance on the field construction of a similar truss type beam-arch combined structure.
本发明公开了一种适用于梁拱组合结构的可升降式施工平台，包括上部桁架、下部平台、驱动机构及电动倒链；上部桁架的两端通过所述电动倒链连接所述下部平台；上部桁架包括左桁架和右桁架，所述左桁架和所述右桁架通过法兰连接，左桁架和所述右桁架均采用若干方管组装而成，所述上部桁架的两端各焊接两个上吊耳，通过U型卡安装所述电动倒链，所述上部桁架的两侧各设置至少一组限位轮。本发明能够有效降低高空作业安全风险、适应拱弦区域不等高度位置作业。通过创新设计施工平台应用，有效解决钢结构桥梁梁底高空作业，提高现场施工效率、减低了施工成本，确保了施工安全及质量，对类似桁架式梁拱组合结构现场施工具有示范意义。
