H-shaped steel beam column joint bolt replacement method and jacking device
The invention relates to the technical field of structure reinforcement, in particular to an H-shaped steel beam column joint bolt replacement method and a jacking device. The H-shaped steel beam column joint bolt replacement method comprises the steps that S1, preset jacking force F is applied to the part, located between a bolt and load, of an H-shaped steel beam, so that the bending moment value of the position, where the bolt is located, of the H-shaped steel beam is zero; and S2, the bolt is disassembled. According to the H-shaped steel beam column joint bolt replacement method, the bending moment value of the position where the bolt is located before unloading is in a small state by applying the jacking force to the H-shaped steel beam between the bolt and the load, so that a flange welding seam of the splicing part of the H-shaped steel beam is prevented from cracking, the shear force value of the position where the bolt is located is relatively small at the moment, and the bolt is convenient to replace; and the method can improve the efficiency of replacing the bolts of the H-shaped steel beam column joint, well solves the problem that the bolts of the H-shaped steel beam column joint cannot be effectively replaced by the existing method, and is suitable for reinforcing design units or reinforcing construction units.
本发明涉及结构加固技术领域，具体地涉及一种H型钢梁柱节点螺栓更换方法和顶升装置。一种H型钢梁柱节点螺栓更换方法，包括：S1、在H型钢梁位于螺栓与载荷之间的部分上施加预设的顶升力F，使所述H型钢梁上所述螺栓所在处的弯矩值为零；S2、拆卸所述螺栓。本发明所述的H型钢梁柱节点螺栓更换方法，通过在螺栓与载荷之间的H型钢梁上施加顶升力来使得螺栓在卸载前所在处的弯矩值处于较小状态，从而防止H型钢梁拼接部位翼缘焊缝开裂，此时螺栓所在处的剪力值相对较小，便于螺栓的更换，本方法可以提高H型钢梁柱节点螺栓更换的效率，很好地解决了现有方法无法有效更换H型钢梁柱节点的螺栓的难题，适用于加固设计单位或加固施工单位使用。
