Development and experimental study of high strength bolt fall prevention device for steel truss bridge
There are many factors that affect the fall of high-strength bolts.Although measures are taken to control the structural stress,materials,processing,construction,and other aspects,it is difficult to completely prevent the occurrence of bolt fall.This article focuses on the problem of high-strength bolt fall,studies control measures to prevent bolt fracture from falling from a passive control perspective,develops bolt fall prevention devices,and conducts static tensile performance tests.The test results indicate that the developed high-strength bolt fall prevention device for steel truss bridge can meet practical engineering needs and avoid major traffic accidents caused by bolt falls,such as vehicle damage and fatalities.
