Construction method for super high-rise steel structure supporting system
The invention discloses a construction method for a super high-rise steel structure supporting system, and relates to the technical field of high-rise steel structure construction.The construction method comprises the steps that profile steel supports and steel beams connected with the profile steel supports are fixed through temporary fixing bolts on a working platform according to a construction design drawing, and then the profile steel supports and the steel beams form an integral unit through reinforcing devices; hoisting the reinforced integral unit and mounting a steel beam at a specified position according to the requirement of a construction drawing; after the steel beam is installed, the reinforcing device is dismantled, meanwhile, fixing and hoisting of a next unit are conducted, a pulley inhaul cable tool is used for aligning a profile steel support and a connecting bracket, a temporary fixing bolt is replaced with a high-strength bolt and fixed, at the moment, the high-strength bolt only needs to be screwed initially, and the applied torque To is equal to 0.065 * Pc * d; pc is the pretension force of the high-strength bolt; d is the diameter of the bolt; after all the steel beams are installed, the high-strength bolts are finally screwed within 24 hours after initial screwing, the applied torque Tc is equal to k * Pc * d, k is a torque coefficient, and finally the flanges of the profile steel supports are welded to the brackets. According to the construction method, the construction efficiency is greatly improved, the construction cost is reduced, and the construction safety is improved.
本发明公开了一种用于超高层钢结构支撑系统的施工方法，涉及高层钢结构施工技术领域，包括根据施工设计图在工作平台上将型钢支撑与相连接的钢梁用临时固定螺栓固定，再通过加固装置将型钢支撑与钢梁形成一个整体单元；将加固后的整体单元起吊并按照施工图纸的要求在规定的位置安装钢梁；钢梁安装后将加固装置拆除，同时进行下一单元的固定与起吊，利用滑轮拉索工具将型钢支撑与连接牛腿进行对正，用高强螺栓替代临时固定螺栓并固定，此时高强螺栓只需初拧，所施加的力矩To=0.065*Pc*d；Pc为高强螺栓预拉力；d为螺栓直径；所有钢梁全部安装后，将高强螺栓终拧，终拧需在初拧后24小时内完成，此时施加的力矩Tc=k*Pc*d，k为扭矩系数，最后将型钢支撑的翼缘与牛腿施焊。本申请的施工方法，大大提高施工效率，降低施工成本，提升施工安全性。
