Steel-wood combined vertical column and construction method thereof

Abstract

The invention discloses a steel-wood combined vertical column and a construction method thereof. A steel bottom plate is welded on the bottom end of a round steel tube; a steel top plate is welded on the top end of the round steel tube; connecting joints are respectively welded on the outer sides of the steel bottom plate and the steel top plate; the round steel tube is internally and symmetrically provided with two square wood columns; the square wood columns are put in the round steel tube through square holes in the steel top plate, and thus the bottom ends of the square wood columns are contacted with the steel bottom plate, and the side surfaces of the square wood columns are in contact with constraint steel plates; the plurality of constraint steel plates are arranged between the two square wood columns at intervals, and are connected with one another through connecting reinforcing steel bars in advance, wherein the constraint steel plate at the uppermost surface is welded on the bottom of the steel top plate. According to the steel-wood combined vertical column and the construction method, not only can the cross sections of the vertical column be reduced, the building space occupied by the vertical column can be reduced, but also the engineering cost can be lowered greatly when the stress requirement is met.

Description

technical field [0001] The invention relates to a structural component in the construction field and a construction method thereof, in particular to a column suitable for various building constructions and large-span space grids and a construction method thereof. Background technique [0002] At present, the columns of house buildings and large-span space grids generally adopt reinforced concrete structural columns or steel columns. Due to its poor bending resistance and overall stability, the reinforced concrete structural column usually has a large cross-section, which not only increases the cost, but also occupies a large internal space of the building, affecting the use of the building; while the steel column is due to Steel is used, not only the cost is very high, but also the production of steel will cause huge energy consumption and environmental pollution. At present, only a few buildings use steel columns as columns. Contents of the invention [0003] The present...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims to solve the technical problems of the existing reinforced concrete columns with large cross-sectional area, large building space, high cost of steel columns, and waste of energy. It provides a steel-wood composite column and its construction method, which can reduce the cross-section of the column , and under the premise of meeting the force requirements, the project cost is greatly reduced
