[0002] With the rapid development of the economy, in order to ensure the structural stability and construction speed, steel columns are widely used in the concrete structures of building construction. The steel columns work together with the concrete, having the characteristics of high stiffness and good ductility, and are particularly suitable for large-span and high-seismic-demand scenarios.

[0003] In traditional steel-concrete columns, the design of the steel section often uses a single I-beam type to cooperate with concrete pouring to form the required support structure, and its overall stability is not high enough. Traditional steel-concrete columns are only applicable to low-rise buildings. For the construction of existing high-rise and super-high-rise buildings, higher structural performance requirements are needed for the support structure, especially the torsional resistance. Traditional structures generally use I-beams for welding to increase the overall height to meet the use requirements, but it is difficult to meet the construction requirements of super-high-rise buildings.

[0022] Figure 1 is a schematic overall sectional view of the present invention; Figure 2 is a schematic view of b1-b1 of the present invention; Figure 3 is a schematic view of c1-c1 of the present invention; Figure 4 is a schematic view of e1-e1 of the present invention; Figure 5Schematic diagram of the upper part of the "cross"-shaped I-beam body of the present invention; As shown in the figure, a concrete steel column structure includes an upper steel column assembly, a lower steel column assembly, and a connecting box-shaped column assembly connecting the upper steel column assembly and the lower steel column assembly; The upper end and the lower end of the connecting box-shaped column assembly are respectively fixedly connected to the upper steel column assembly and the lower steel column assembly in a corresponding manner and are cooperated with concrete pouring to form a columnar structure; For the concrete steel column structure of this technical solution, the connecting box-shaped column assembly is used to connect and install between the upper steel column assembly and the lower steel column assembly, and subsequent corresponding pouring construction is carried out to ensure the structural strength and torsional and bending resistance of the overall structure, and improve the construction quality.

[0023] In this embodiment, the connecting box-shaped column assembly includes a box-shaped upper plate 10, a box-shaped lower plate 9, and a supporting steel column; The box-shaped upper plate 10 and the box-shaped lower plate 9 are respectively fixedly connected to the upper end and the lower end of the supporting steel column in a corresponding manner, and the upper steel column assembly is fixedly connected and installed in cooperation with the box-shaped upper plate. The cross-section of the supporting steel column as a whole is rectangular in the horizontal direction. The upper end of the supporting steel column is fixedly connected to the box-shaped upper plate 10, and the lower end of the supporting steel column is fixedly connected to the box-shaped lower plate 9. Its overall structure forms a box structure. Compared with the traditional steel welding method, on the one hand, it provides a better installation position for the upper and lower steel sections, and on the other hand, compared with the result of traditional direct welding forming, it has better torsional and bending resistance.

[0024] In this embodiment, the box-shaped upper plate 10 is rectangular as a whole, and a "cross"-shaped steel bar 17 connecting the inner walls of the box-shaped upper plate is arranged in the middle of the box-shaped upper plate 10, and an upper plate grouting hole 18 is opened in the middle of the box-shaped upper plate 10. The "cross"-shaped steel bar 17 is arranged on the box-shaped upper plate 10 to play a role in strengthening the structure. Four upper plate grouting holes 18 with the same structure are opened at the central position, which is convenient for subsequent grouting construction.

[0025] In this embodiment, the box-shaped lower plate 9 and the box-shaped upper plate 10 are arranged parallel to each other, and the box-shaped upper plate 9, the box-shaped lower plate 10, and the supporting steel column as a whole form a cuboid structure, and a plurality of stud bolts 7 are arranged parallel to each other in the circumferential direction of the supporting steel column. A plurality of stud bolt 7 structures are evenly distributed in the circumferential direction of the overall structure of the box-shaped upper plate 9, the box-shaped lower plate 10, and the supporting steel column, so that after it is poured with concrete 11, its performance after pouring and forming is better, and the connection between the concrete and the steel structure is closer. Due to the position factor of the connection position, the density of the stud bolts 7 arranged on its surface is higher than that of the lower steel column assembly and the upper steel column assembly, ensuring that the performance meets the use requirements.

[0026] In this embodiment, the lower steel column assembly includes a cross-shaped I-beam body 13, an inner ring plate 6 disposed on the cross-shaped I-beam body 13, and stud bolts 7 disposed on the outer surface of the cross-shaped I-beam body; the upper end of the cross-shaped I-beam body 13 is connected and installed in cooperation with a box-shaped lower plate 9. The lower steel column uses a cross-shaped I-beam, which has stronger performance compared to the traditional I-beam structure. The structural performance of the lower steel column is further improved through the setting of the inner ring plate 6. Correspondingly, a stud bolt structure is also provided on the outer surface of the cross-shaped I-beam body 13 to facilitate the improvement of the structural performance after subsequent pouring.

[0027] In this embodiment, the cross-shaped I-beam body 13 includes a transverse I-beam and a longitudinal I-beam that are perpendicular to each other and fixedly connected as a whole, and the inner ring plate 6 is disposed at the intersection of the transverse I-beam and the longitudinal I-beam. The cross-shaped I-beam body 13 is composed of a transverse I-beam and a longitudinal I-beam arranged perpendicular to each other. An inner ring plate 6 structure is correspondingly provided at the connection of the transverse and longitudinal I-beams and is evenly distributed along the height direction of the I-beam to ensure that the structural performance of the I-beam structure as the bottom support meets the usage requirements.

[0028] In this embodiment, an arc-shaped connecting plate 8 is provided between the box-shaped lower plate and the upper end of the cross-shaped I-beam body. The setting of the arc-shaped connecting plate 8 ensures that the stress at its connection meets the requirements.

[0029] In this embodiment, the upper steel column assembly 14 includes an upper steel column 15 with a rectangular cross-section as a whole and stud bolts 7 disposed in the circumferential direction of the upper steel column. An upper grouting hole 12 is provided on the upper steel column. The upper steel column 15 uses a steel structure with a rectangular cross-section. After the upper steel column assembly 14 is installed in cooperation with the formwork, grouting construction is carried out through the provided upper grouting hole 12.

[0030] In this embodiment, the bottom support frame assembly includes transverse angle steels 1, longitudinal angle steels 2, a column bottom sealing plate 5, and support tie rods 3; there are two transverse angle steels 1 and the two transverse angle steels 1 are arranged parallel to each other, there are two longitudinal angle steels 2 and the two longitudinal angle steels 2 are parallel to each other, and the transverse angle steels 1 and the longitudinal angle steels 2 are perpendicular to each other; one end of the support tie rod 3 is locked and installed in cooperation with the transverse angle steel and the longitudinal angle steel, and the other end of the support tie rod 3 passes through the column bottom sealing plate 5 and is locked and installed. As Figure 1 Figure 4 shown, the mutually perpendicular transverse and longitudinal angle steels serve as the bottom support, and an alternating structure is formed at the bottom for easy installation construction. The column bottom sealing plate 5 is installed in cooperation with the cross-shaped I-beam body 13 as a support installation surface to ensure the bottom installation accuracy.

[0031] In this embodiment, a secondary grouting layer 4 is formed by pouring at the lower end of the column bottom sealing plate to ensure the overall performance of the construction is guaranteed.
