Construction method of bridge high-strength bolt
The invention discloses a construction method of a bridge high-strength bolt, and relates to the technical field of bolt construction. The construction method comprises the following steps of screwinga nut by first torque to tighten the bolt, and the first rotation angle of the nut and the first axial force of the bolt after the nut is rotated for the first time are measured; increasing the torque to continuously rotate the nut at a second torque, measuring a second rotation angle of the nut and a second axial force of the bolt after the nut is rotated for the second time, and calculating a linear relation coefficient of the bolt axial force and the nut rotation angle; calculating a third rotation angle, continuously rotating the nut at the third rotation angle, and measuring a third axial force of the bolt after the nut is rotated; if the relative deviation value of the third axial force and the designed axial force is smaller than the preset relative deviation value, completing construction; and if the relative deviation between the third axial force and the designed axial force is not smaller than the preset relative deviation, calculating a fourth rotating angle, continuing torotate the nut at the fourth rotating angle, and completing construction. The technical problem that after bridge bolt construction, deviation between shaft force and designed shaft force is large can be solved.
本发明公开了一种桥梁高强度螺栓的施工方法，涉及螺栓施工技术领域，该施工方法包括以下步骤：以第一扭矩转动螺母拧紧螺栓，测量第一次转动螺母后螺母的第一转角和螺栓的第一轴力；增加扭矩以第二扭矩继续转动螺母，测量第二次转动螺母后螺母的第二转角以及螺栓的第二轴力，计算螺栓轴力与螺母转动角度的线性关系系数；计算第三转角，以第三转角继续转动螺母，并测量转动螺母后螺栓的第三轴力；若第三轴力与设计轴力的相对偏差值小于预设的相对偏差值，则完成施工；若第三轴力与设计轴力的相对偏差不小于预设的相对偏差，则计算第四转角，以第四转角继续转动螺母，完成施工。本发明能解决桥梁螺栓施工后轴力与设计轴力偏差较大的技术问题。
