Steel Structure Installation Engineering (Construction Method Of Steel Structure-Part 2)

The process flow diagram is as follows:
Members, equipment and personnel preparation→Release line and test line (axis, elevation)→Pre buried bolt acceptance and base surface treatment→Member center line and elevation line→Installation column, beam core framework→High strength bolt initial tightening, final tightening→Column and column node welding→Beam with column, with beam node welding→Flaw detection by ultrasonic→Support member (knee-bracing) installation→Laminated steel plate installation→Welding, bolt connecting→Construction of this section is completed→The next section water section preparations

Steel structure hoisting sequence

The steel structure hoisting is carried out in parallel sequence, according to the division of the region. After an area hoisting, immediately take the measurement, calibration, and high-strength bolt initial tightening process, and when the area correction is finished, take the measurement, calibration, high-strength bolt final tightening, and welding to the entire. Take the hoisting of the next steel column after the retest after welding. And, depending on the situation on-site, perform the laminated plate hoisting and a portion of the laying work.
