Jun 28,2024
The construction and installation of the steel structure can be built by the connection of the steel structure beam and the steel structure column, as well as other components. The connection method of steel structure can be divided into three kinds, one is welding, one is rivet connection, and the other is bolt connection, and bolt connection is divided into ordinary bolt connection and high-strength bolt connection.
1, for the choice of high-strength bolts, we must choose the products of regular manufacturers, Hebei Hantie Fastener Co., LTD. - Fastener professional manufacturer/Hantie Company specializing in fastener production and research and development for more than 30 years.
2, high-strength bolts should be properly kept by a special person, can not be casually thrown, in the process of the installation of the entire steel structure can not hurt the bolts, and can not appear other pollution, to prevent changes in the torque coefficient of the bolts, and the preservation of the environment to moisture-proof and anti-corrosion.
3, when installing high-strength bolts, it is necessary to use a bald crowbar and the screw holes of the upper and lower or front and rear connection plates to allow the bolts to enter freely. If the error of the connecting plate screw hole is relatively large, it should be checked and analyzed and dealt with. If the adjustment of bolt holes is ineffective or the position of the remaining bolt holes is not correct, you can use an electric reamer or a manual reamer to punch holes.
When screwing high-strength bolts, there are two steps, the first step is the initial screwing, and when the steel column or steel beam axis is accurate, the final screwing should be completed within the same day to prevent omissions.
