Bolt mounting method
The invention discloses a bolt mounting method, which is used for fastening and connecting a to-be-assembled steel truss member, and comprises the following steps: setting a part of threaded holes of the steel truss member as preassembled threaded holes; temporary bolts and/or punching nails are put into the pre-assembling threaded holes, fastening operation is carried out, and the steel truss components are pre-assembled; whether the center position of the pre-assembled steel truss component is located at a preset position or not is checked; after it is confirmed that the center position of the pre-assembled steel truss component is located at the preset position, high-strength bolt pairs are put into remaining threaded holes of the steel truss component; fastening operation is conducted on the high-strength bolt pairs in sequence; the temporary bolts and/or the punching nails are/is dismantled; high-strength bolt pairs are put into the vacant preassembled threaded holes, fastening operation is carried out, and the steel truss components are assembled and fixed; the large-span steel truss splicing requirement can be met, the steel truss splicing strength is improved, and therefore the safety performance of the steel truss is improved, and the splicing efficiency is improved.
本发明公开一种螺栓安装方法，螺栓安装方法用于用于紧固连接待拼装的钢桁架构件，螺栓安装方法包括：将钢桁架构件的部分螺纹孔设置为预装螺纹孔；在预装螺纹孔中投放临时螺栓和/或冲钉，并进行紧固作业，对钢桁架构件进行预拼装；检查预拼装的钢桁架构件的中心位置是否处于预设位置；在确认预拼装的钢桁架构件的中心位置处于预设位置后，在钢桁架构件的剩余螺纹孔中投放高强螺栓副；依次对各个高强螺栓副进行紧固作业；拆除临时螺栓和/或冲钉；在空置的预装螺纹孔中投放高强螺栓副，并进行紧固作业，对钢桁架构件进行拼装固定；能够符合大跨度钢桁架拼装要求，提高钢桁架拼装强度，从而提高钢桁架的安全性能，提高拼装效率。
