[0002] In areas where the temperature difference between winter and summer reaches 70 degrees Celsius, the release of the large deformation caused by the temperature difference of the steel structure system requires further improvement. Therefore, a high-rise swinging steel column with a rotatable pin shaft column foot node is designed. By rotating back and forth around the pin shaft of the column foot, the steel column swings to absorb the expansion and contraction deformation of the steel roof.

[0003] When the high-rise swinging steel column is not connected with other structures, its own stability is very poor, and the wind level is also high in areas with large temperature differences. The existing steel column installation method is relatively conventional and cannot guarantee the construction safety and quality precision of such steel columns. To solve the problem of installing swinging steel columns, CN 115653114A discloses a method for installing a row of super-high swinging columns, which connects multiple swinging steel columns into one body by setting a scissors brace therebetween; CN 116220232A discloses an auxiliary installation device for a steel structure swinging column, which sets a receiving base plate at the bottom of the column to control the stability of the swinging column. Although the above-mentioned methods can solve some problems in the installation of swinging steel columns, they are not systematic and cannot provide a systematic specification for the installation of high-rise swinging steel columns.
