Embodiment Construction
[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0053] like Figure 1-14 As shown, a prefabricated and spliced special-shaped steel column is used in steel frame structures and used as corner columns at the corners of buildings, including
[0054] The first steel column 1 includes a first main steel column 11 and a first connecting piece 12 and a second connecting piece 13 respectively fixedly connected with two adjacent sides of the first main steel column 11, the first main steel column 11 It is a steel body with a hollow interior and a square cross section. First installation holes 111 are opened on the four side walls of the lower end of the first main steel column 11. Both the first connecting piece 12 and the second connecting piece 13 are T-shaped. Steel body, the vertical side 121 of the first connector 12 and the vertical side 131 of the second connector 13 are respectively vert...

The invention relates to an assembly type spliced special-shaped steel column. The assembly type spliced special-shaped steel column is formed by assembling a first steel column and a third steel column placed up and down, or a first steel column, N second steel columns and a third steel column placed in sequence from top to bottom, wherein the first steel column comprises a first main steel column, a first T-shaped connecting piece and a second T-shaped connecting piece; the first T-shaped connecting piece and the second T-shaped connecting piece are respectively and fixedly connected to thetwo adjacent side edges of the first main steel column; the first main steel column is a steel body with the hollow interior and the square cross section; the vertical edges of the first connecting piece and the second connecting piece are respectively and vertically fixed to the middle parts of the two adjacent side edges of the first main steel column; a mounting hole is formed in the lower endof the first steel column; the second steel columns and the third steel column have the same structure as the first steel column; and the difference is that mounting holes are formed in the upper andlower ends of the second steel columns, and a mounting hole is formed in the lower end of the third steel column. The invention also discloses a construction method. The assembly type spliced special-shaped steel column has the advantages of convenient construction, reliable connection, effective reduction of the cross section size and improvement of bearing capacity and stress.
Description
technical field [0001] The invention relates to an assembled and spliced special-shaped steel column and a construction method thereof, belonging to the field of structural engineering. Background technique [0002] Most of the columns of large and medium-sized industrial plants (plants constructed of steel pipe concrete columns), long-span public buildings, high-rise buildings, light mobile homes, working platforms, trestles and supports, etc., use steel columns. In recent years, the development of prefabricated steel structure building technology has received widespread attention from the central government, local governments at all levels and all walks of life. For the steel frame structure, the structural system has basically matured, but for the corner columns in the frame structure, the cross-sectional form used is still mainly H-shaped or box-shaped. The outstanding problem of this section is that once the structure is subjected to a large load, the section size ne...
