Abstract

The invention relates to a combined steel column, and in particular relates to a multi-tube combined steel column and a manufacturing method thereof, belonging to the field of steel structures. The multi-tube combined steel column comprises a bottom column plate, wherein a main steel tube component is arranged at the upper part of the bottom column plate; the main steel tube component is sleeved by an outer circular partitioning plate; a small steel tube component fixed together with the main steel tube component is arranged at the upper part of the bottom column plate; a plurality of anti-shearing buttons are arranged at the bottom of the bottom column plate. The multi-tube combined steel column and the manufacturing method thereof are compact in structure, low in manufacturing cost and high in assembling precision.

Description

technical field [0001] The invention relates to a composite steel column, in particular to a multi-pipe composite steel column and a manufacturing method thereof, belonging to the field of steel structures. Background technique [0002] Traditional composite steel columns have low strength, complex assembly, and relatively high manufacturing costs, which cannot meet existing needs. [0003] Chinese patent 201010265503.3 discloses a combined steel column, which includes: an upper section column and a lower section column; a transition connecting plate is provided at the bottom of the lower section column, and the upper section column is connected to the lower section column through the transition connecting plate. Its structural performance is relatively poor, and its bearing capacity is poor, so it cannot meet the existing needs. Contents of the invention [0004] The invention mainly solves the deficiencies in the prior art, and provides a multi-pipe composite steel colu...
