Description

technical field [0001] The present invention relates to a high-strength fastener, more particularly to a bolt. Background technique [0002] Bolts are one of the most important connection methods in building steel structures. They mainly include ordinary bolts, friction-type high-strength bolts and pressure-bearing high-strength complex acids. They belong to steel complex acids, but they will bring cold bridges, Unfavorable phenomena such as conduction will cause a series of electrochemical corrosion problems, leading to corrosion of bolts, affecting the stability of the building structure, and ultimately affecting the normal use of the building. A circuit breaker is an electrical protection device installed between a power supply and a load unit to protect motors, transformers, and load units of power transmission lines from accidents caused by large currents in power transmission lines caused by short circuits or ground faults. Usually, the static and dynamic contacts of ...
