Treating method for high-strength bolt friction type connection friction contact surface
The invention relates to a treating method for a high-strength bolt friction type connection friction contact surface, and belongs to the technical field of construction steel structure and surface modification. The treating method solves the problem that the anti-sliding coefficient of a stainless steel structure friction connection surface treated by an existing treatment method is only about 0.2, and the requirement that the anti-sliding coefficient of the high-strength bolt friction type connection friction surface in the steel structure standard is not less than 0.45 cannot be met, and the high-strength bolt friction type connection mode cannot be applied to a stainless steel structure. The treating method for the high-strength bolt friction type connection friction surface of the stainless steel structure is characterized in that a contact surface A and a contact surface B of two stainless steel plates connected with a high-strength bolt are subjected to shot blasting treatment and supersonic flame thermal spraying treatment respectively. According to the treating method, the anti-sliding coefficient of the high-strength bolt friction type connection friction surface can be larger than or equal to 0.45, so that the stainless steel structure adopts the installation connection mode-high-strength bolt friction type connection with higher reliability and higher precision.
本发明涉及一种高强螺栓摩擦型连接摩擦接触面的处理方法，属于建筑钢结构和表面改性技术领域，解决了现有处理方法处理的不锈钢结构摩擦连接表面抗滑移系数仅为0.2左右，不能满足钢结构标准中对高强螺栓摩擦型连接摩擦面抗滑移系数不小于0.45的要求，不能将高强螺栓摩擦型连接方式应用于不锈钢钢结构中的问题。一种不锈钢钢结构高强螺栓摩擦型连接摩擦面处理方法，对高强螺栓连接的两个不锈钢板件的接触面A、接触面B分别进行喷丸处理和超音速火焰热喷涂处理。本发明的处理方法能够使高强螺栓摩擦型连接摩擦面的抗滑移系数大于等于0.45，进而实现不锈钢钢结构采用更可靠精度更高的安装连接方式‑高强螺栓摩擦型连接。
