Concrete-filled steel tube beam column connecting joint for jacking storey-adding of steel slide way and mounting method of concrete-filled steel tube beam column connecting joint
The invention discloses a concrete-filled steel tube beam column connecting joint for jacking storey-adding of a steel slide way and a mounting method of the concrete-filled steel tube beam column connecting joint. When a steel slide way jacking technology is adopted for carrying out storey-adding transformation on an existing building, the elevation of a steel plate used for connecting longitudinal load-bearing steel bars of a newly-added beam surface and a beam bottom is reversely deduced through the elevation of a newly-added storey plate surface and the beam height, and the height of the steel plate is adjusted according to the height of a standard engineering cushion block and the initial elevation of a column foot on the basis of the elevation. The number of standard cushion blocks is adopted for adjustment, the height of engineering cushion blocks used for adjusting the elevation is adjusted through a lossless cutting technology or steel plates are adopted, and the problem of collision of the steel corbels needs to be considered at the same time during elevation adjustment, that is, in the beam height range, when the elevation of the steel corbels is adjusted for the first time, two steel plates at the elevation H1 need to be crossed, and the steel corbels are not collided. When the elevation of the steel corbel is adjusted for the second time, a plurality of steel plates at the elevation H2 need to be spanned. According to the construction method, newly-added beam support ribs are communicated with adjacent beam steel bars, safety and reliability are achieved, the elevation can be accurately controlled through lossless cutting or steel plate adjustment in the construction process, and the construction precision is improved.
本发明公开了一种钢滑道顶升增层用钢管混凝土梁柱连接节点及安装方法。在采用钢滑道顶升技术进行既有建筑增层改造时，通过新增楼层板面标高及梁高，反推用于连接新增梁面、梁底纵向受力钢筋的钢板所在标高，并在此标高基础上根据标准工程垫块高度及柱脚起始标高，调整采用标准垫块数量和采用无损切割技术调整用于调整标高的工程垫块高度或采用钢板，此标高的调整需同时考虑钢牛腿的碰撞问题，即在梁高范围内，第一次调整钢牛腿标高时需跨越标高H1处两块钢板，第二次调整钢牛腿标高时需跨越标高H2处多块钢板。该施工方法将新增梁支座筋与相邻梁钢筋贯通，安全可靠在施工过程中通过无损切割或钢板调节可精准控制标高，提高施工精度。
