Embodiment Construction

[0020] Such as figure 1 As shown, the steel-steel tube concrete cross-shaped column of the present invention mainly includes the outer steel tube 1, the inner filling concrete 7 and the inner truss system. Among them, the outsourcing steel pipes are four members with ∏-shaped cross section, and the corners are fixedly connected with stiffeners 6 . The outer steel pipe is fixedly connected with the inner truss system to form a column with a cross-section. In this column, the section steel is located at the centerline of the column, coincident with the center of the column.

[0021] The inner truss system mainly includes section steel 2, angle steel 4, pressure sleeve 5 and tie rod 3. The cross-section of the shaped steel is cross-shaped, and its webs are perpendicular to each other or on the same plane, and the ends of the webs are provided with flange plates 21 . The cross-section of the angle steel is Γ-shaped, and the number is 4. On the four webs of the profiled steel, ...

Abstract

The invention discloses an inner truss system, a shape steel-steel pipe concrete cross column and a method for constructing the same. The shape steel-steel pipe concrete cross column comprises outer wrapping steel pipes, inner filled concrete and the inner truss system. The inner truss system comprises shape steel with a crossed transverse section, angle steel with an inverted-L-shaped transverse section, pressure sleeves and draw bars. The pressure sleeves are longitudinally arranged on web plates of the angle steel and the shape steel along a truss system, two ends of each draw bar are respectively fixedly connected with the corresponding pressure sleeve on the corresponding web plate of the shape steel and the corresponding pressure sleeve on the angle steel, and the angle steel is distributed to form quadrilaterals; the angle steel is fixedly connected with the outer wrapping steel pipes. The inner truss system, the shape steel-steel pipe concrete cross column and the method have the advantages that the bearing capacity and the shear capacity of column components can be improved by the steel pipes and the inner truss system, the ductility of the components can be obviously improved, and the anti-seismic capacity of structures can be enhanced; outer planar support effects can be realized by inner trusses for the web plates of the shape steel, accordingly, width-thickness ratios and height-thickness ratios of the web plates can be decreased, and the stability of the web plates can be improved.

Description

technical field [0001] The invention relates to a building special-shaped column, in particular to a shaped steel-steel tube concrete column and a construction method thereof. Background technique [0002] The infill wall of the frame structure does not bear the load in the design, and the load of the floor is finally borne by the frame column and transmitted to the next floor. With the gradual increase of the number of floors of the building, the load borne by the frame columns is also increasing, which requires the continuous increase of the column section. The traditional rectangular column section, due to its large section, will protrude from the wall, resulting in the occupation of indoor space. In order to solve this problem, some buildings currently use special-shaped columns at the corners of the building. [0003] But there are still many problems in the existing special-shaped column. Contents of the invention [0004] After research and experiments, the appli...
