Hoisting method of steel structure
The invention relates to the technical field of building construction, in particular to a steel structure hoisting method which comprises the following steps: rechecking basic parameters and marking components; the steel column is hoisted through a rotary hoisting method, and the elevation, perpendicularity and displacement of the steel column are controlled through a theodolite; temporary alignment vertical plates are installed on the two sides of each end of the crane beam respectively, the crane beam is lifted to the positions above the two steel column brackets and gradually lowered, the alignment vertical plates abut against the steel column brackets to guide the crane beam, and meanwhile the alignment vertical plates are matched with the outer wedge-shaped faces arranged at the two ends of the crane beam and the inner wedge-shaped face arranged between the two steel column brackets, so that the crane beam is installed at the designed position. The perpendicularity and center deviation of the steel column are controlled through careful reinspection before hoisting and the theodolite, the installation position deviation of the steel column is reduced, the installation quality of the steel column is improved, meanwhile, the alignment vertical plates arranged on the two sides of the crane beam are matched with the wedge-shaped face of the steel column bracket in a multi-direction guiding mode, the crane beam can automatically fall into the design position, and the construction efficiency is improved. The hoisting efficiency is improved.
本申请涉及建筑施工的技术领域，尤其是涉及一种钢结构的吊装方法，包括复验基础参数、构件标线；采用旋转吊装法将钢柱吊装，并用经纬仪对钢柱标高、垂直度和位移进行控制；在吊车梁各端部的两侧分别安装临时对位立板，将吊车梁吊起到两个钢柱牛腿上方并逐渐下放，对位立板抵靠钢柱牛腿引导吊车梁，同时配合吊车梁两端设有的外楔形面与两个钢柱牛腿之间设有的内楔形面，使吊车梁安装到设计位置。本申请通过吊装前细致的复验和经纬仪控制钢柱垂直度和中心偏移，减小了钢柱安装位置偏差，提高了钢柱安装质量，同时利用吊车梁两侧设置的对位立板和钢柱牛腿楔形面的多方向导向配合，使吊车梁能自动落入设计位置，提高吊装效率。
