Problems solved by technology

[0002] With the rapid development of high-rise buildings in my country, the floors are getting higher and higher, which brings great challenges to the installation technology of high-rise steel structures. Among them, the structural form of high-rise steel structure columns changes with the increase of floor heights. The number of segments also increases accordingly. The installation of steel columns is carried out by adopting the current traditional steel support or temporary steel column fixing measures such as pulling cable wind ropes and using jacks or inverted chains for straightening, which is very useful for the installation of high-rise and super high-rise structures. It is very difficult, the construction personnel are unfavorable to operate, it is difficult to adjust the steel column, and it is difficult to achieve the installation accuracy of the steel column. Increased construction technical measures and labor input, increased workload and working hours, increased construction costs, and it is difficult to guarantee the construction period, and there are many insecurities in the three-dimensional intersection operation of multiple types of work and multiple processes

Abstract

The invention relates to a steel column butt joint adjustment fixing device and method. The steel column butt joint adjustment fixing device comprises upper T-shaped connecting pieces and lower T-shaped connecting pieces, and vertical plates of the upper T-shaped connecting pieces and vertical plates of the lower T-shaped connecting pieces are separately and fixedly mounted on lug plates of the butting ends of an upper steel column and a lower steel column through high-strength bolts, wherein the upper steel column and the lower steel column are in butt joint. Corresponding bolt holes are separately formed in horizontal plates of the upper T-shaped connecting pieces and horizontal plates of the lower T-shaped connecting pieces and the horizontal plates of the upper T-shaped connecting pieces and the horizontal plates of the lower T-shaped connecting pieces are connected through screws and nuts. After the upper steel column is hoisted in position, the upper T-shaped connecting pieces are moved up and down by adjusting the nuts on the screws, so that the upper steel column is driven to move to adjust the weld gap of steel column connecting openings and the verticality of the upper steel column. After the upper steel column is adjusted to the required accuracy, the nuts at the upper and lower ends of the horizontal plates of the upper T-shaped connecting pieces are tightened to fix the upper steel column. According to the steel column butt joint adjustment fixing device and method, the problem that a cable rope and a support are inconvenient to install and fix is solved, the work efficiency is greatly improved, the structure is simple, the construction is convenient, the three-dimensional cross work of the construction personnel is avoided, and the safety of the construction personnel is ensured.
