The partition through connection comprises an all-bolt partition through node. The inner partition plate type node is not easy to weld, and the pouring of concrete in the pipe is influenced, so that the inner partition plate type node is influenced by the side length of the concrete filled steel pipe column in application.

The partition plate through node integral node section can be prefabricated in a factory, a receiving mechanism is clear, buckling deformation of a column wall can be reduced, bearing capacity is high, and a strong node and a weak member of the structure can be realized.
The existing partition plate through node has the defects of large on-site welding quantity, secondary welding at the connecting position of the partition plate and the steel column and difficulty in ensuring the welding quality. Although the full-bolt partition plate through joint reduces the field welding amount, the steel beam and the rectangular concrete-filled steel tube column still need to be installed on the field. Due to the fact that the precision of the existing member manufacturing in China is not enough, the phenomenon that the steel beam cannot be installed due to errors of bolt hole positions exists in many times.
