Reverse-jacking arching installation method for ultrahigh heavy-load high-strength bolt connection inverted-delta-shaped stoplog
The invention relates to an ultra-high heavy-load high-strength bolt connection inverted-delta-shaped stoplog reverse-jacking arching installation method. The method comprises the steps that 1, down-warping numerical values of an upper stoplog and a lower stoplog are calculated; 2, the lower stoplog is installed in place; 3, an arching adjusting cushion block is installed; 4, the upper double stoplogs are sequentially installed in place; 5, connecting and fixing an upper double-stoplog flange plate; 6, connecting and fixing the upper double-stoplog end plate and the column; 7, a jacking frame is installed, and the arching adjusting cushion block is removed; 8, jacking the lower stoplog; 9, connecting and fixing the superposed surfaces of the upper and lower laminated beams through bolts; and step 10, connecting and fixing the lower stoplog end plate. According to the method, the inverted-delta-shaped stoplog is installed in a reverse jacking and arching mode, and the ultrahigh heavy-load high-strength bolt connection inverted-delta-shaped stoplog is installed economically, rapidly and efficiently.
本发明涉及一种超高重载高强螺栓连接倒品字形叠梁反顶起拱安装方法，步骤1、上下叠梁下挠数值计算；步骤2、下叠梁安装就位；步骤3、起拱调整垫块安装；步骤4、上部双叠梁依次安装就位；步骤5、上部双叠梁法兰板连接固定；步骤6、上部双叠梁端板与柱连接固定；步骤7、安装顶升架并撤除起拱调整垫块；步骤8、下部叠梁顶升；步骤9、上下部叠梁叠合面螺栓连接固定；步骤10、下叠梁端板连接固定。本发明通过对倒品字形叠梁采取反顶起拱的安装方法，实现超高重载高强螺栓连接倒品字形叠梁经济、快速、高效安装。
