| Abstract: | The concrete filled steel tube columns of Shengu compression engine experimental workshop have some characteristics, such as large quality and volume, irregular shape, and dense and heavy of sectional area of welded seams. The assemble technology of the special mould of the CFST columns and use the one-sided welding forming welding technology are introduced, other technologies of welding reverse deformation, rigid fixing, reserved welding shrinkage and so on also are introduced. Some problems such as assembly process and big welding deformation of concrete filled steel tube columns, difficulty to control of connection precision are solved which have good effect. |
