Steel structure work high-strength bolt and using method thereof

The invention belongs to the field of machines, and relates to a steel structure work high-strength bolt. The steel structure work high-strength bolt is mainly used for steel structure connection and fixing, and comprises a screw rod, a nut and gaskets. The steel structure work high-strength bolt is characterized in that the number of the gaskets is two, one gasket is the common gasket, the other gasket is the pressure indicating gasket, the pressure indication gasket comprises a metal shell, the metal shell is an annular sealing cavity, and the cavity is filled with silica resin liquid; a plurality of protrusions are arranged on the metal shell. The thickness of the metal wall at the positions of the protrusions is 1/3-2/1 smaller than that of the metal wall at other positions of the outer shell. Silica resin sprayed out of the pressure indicating gasket is qualified, the sprayed silica resin can be solidified on the periphery of the pressure indicating gasket, and is the striking mark inevitably generated after bolt solidification is qualified, missing marking and error marking caused by manmade omissions do not exist, therefore, missing screwing and repeated screwing cannot happen, and mounting quality can be effectively guaranteed.
