Description

Technical Field

[0001] This invention relates to the field of building construction, and more specifically to a concrete-steel column structure for high-rise building construction. Background Technology

[0002] With rapid economic development, steel columns are increasingly used in concrete structures to ensure structural stability and construction speed. Steel columns work together with concrete, combining high stiffness and good ductility, making them particularly suitable for large-span structures and scenarios with high seismic requirements.

[0003] In traditional steel-concrete composite columns, the steel structure is often designed using a single I-beam combined with concrete pouring to form the required support structure. However, its overall stability is not high enough. Traditional steel-concrete composite columns are only suitable for low-rise buildings. For the construction of existing high-rise and super high-rise buildings, the structural performance requirements of the support structure are higher, especially the torsional performance. Traditional structures generally use welded I-beams to increase the overall height to meet the usage requirements, which is difficult to meet the construction needs of super high-rise buildings.

[0004] Therefore, to solve the above problems, a concrete-steel column structure for high-rise building construction is needed to address the aforementioned production issues. Summary of the Invention

[0005] In view of this, the concrete steel column structure of this technical solution for high-rise building construction is connected and installed by connecting box-type column components between the upper steel column components and the lower steel column components, followed by corresponding pouring construction, to ensure the structural strength and torsional and bending resistance of the steel connection parts. The bottom support frame component ensures the stability and reliability of the bottom structure of the steel column, thereby improving the overall construction quality.

Multiple studs are arranged in parallel to each other in the outer circumferential direction of the supporting steel columns.

[0010] Furthermore, the lower steel column assembly includes a cross-shaped I-beam body, an inner ring plate disposed on the cross-shaped I-beam body, and studs disposed on the outer surface of the cross-shaped I-beam body; the upper end of the cross-shaped I-beam body is connected and installed in conjunction with the box-shaped lower plate.

The bottom support frame assembly ensures the stability and reliability of the bottom structure of the steel column, improving the overall construction quality.

[0025] In this embodiment, the connecting box-type column assembly includes a box-type upper plate 10, a box-type lower plate 9, and a supporting steel column. The box-type upper plate 10 and the box-type lower plate 9 are respectively fixedly connected to the upper and lower ends of the supporting steel column. The upper steel column assembly is fixedly connected to the box-type upper plate. The supporting steel column has a rectangular cross-section along the horizontal direction. The upper end of the supporting steel column is fixedly connected to the box-type upper plate 10, and the lower end of the supporting steel column is fixedly connected to the box-type lower plate 9. The overall structure forms a box structure. Compared with the traditional steel welding method, it provides a better installation position for the upper and lower steel sections, and it has better torsional and bending resistance than the result of traditional direct welding.

[0026] In this embodiment, the box-shaped upper plate 10 has an overall rectangular structure. A cross-shaped steel bar 17 connecting to the inner wall of the box-shaped upper plate 10 is provided in the middle of the upper plate 10. A grouting hole 18 is opened in the middle of the box-shaped upper plate 10. The cross-shaped steel bar 17 on the box-shaped upper plate 10 serves to strengthen the structure, and four identical grouting holes 18 are opened at its center to facilitate subsequent grouting construction.

[0027] In this embodiment, the lower box-shaped plate 9 and the upper box-shaped plate 10 are arranged parallel to each other. The upper box-shaped plate 9, the lower box-shaped plate 10, and the supporting steel column form a cuboid structure. Multiple studs 7 are arranged parallel to each other on the outer periphery of the supporting steel column. The upper box-shaped plate 9, the lower box-shaped plate 10, and the supporting steel column have multiple studs 7 evenly distributed on their outer periphery. This results in better performance after the concrete 11 is poured, and a tighter connection between the concrete and the steel structure. Due to the location of the connection point, the density of the studs 7 on its surface is higher than that of the lower and upper steel column assemblies, ensuring that the performance meets the usage requirements.

[0028] 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 studs 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 with a box-shaped lower plate 9. The lower steel column adopts a cross-shaped I-beam, which has stronger performance than the traditional I-beam structure. The inner ring plate 6 further improves the structural performance of the lower steel column. Correspondingly, the outer surface of the cross-shaped I-beam body 13 is also provided with a stud structure, which facilitates the improvement of structural performance after subsequent pouring.

[0029] In this embodiment, the cross-shaped I-beam body 13 includes horizontal and vertical I-beams that are perpendicular to each other and fixedly connected as a whole. The inner ring plate 6 is disposed at the junction of the horizontal and vertical I-beams. The cross-shaped I-beam body 13 is composed of horizontal and vertical I-beams arranged perpendicularly to each other. The inner ring plate 6 structure is provided at the junction of the horizontal and vertical I-beams and is evenly distributed along the height direction of the I-beam to ensure that the performance of the I-beam structure serving as the bottom support meets the usage requirements.

[0030] 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 arc-shaped connecting plate 8 ensures that the stress at the connection point meets the requirements.

[0031] In this embodiment, the upper steel column assembly 14 includes an upper steel column 15 with a rectangular cross-section and studs 7 arranged 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 is a steel structure with a rectangular cross-section. After the upper steel column assembly 14 is installed with the template, grouting is performed through the upper grouting hole 12.

[0032] In this embodiment, the bottom support frame assembly includes transverse angle steel 1, longitudinal angle steel 2, column base sealing plate 5, and support rod 3; there are two transverse angle steel 1s arranged parallel to each other, and there are two longitudinal angle steel 2s arranged parallel to each other, while the transverse angle steel 1s and longitudinal angle steel 2s are perpendicular to each other; one end of the support rod 3 is locked in place with the transverse and longitudinal angle steels, and the other end of the support rod 3 passes through the column base sealing plate 5 and is locked in place. Figure 1 Figure 4 As shown, the mutually perpendicular horizontal and vertical angle steels serve as bottom supports, forming an interlaced structure at the bottom to facilitate installation. The column bottom sealing plate 5 is installed in conjunction with the "+" shaped I-beam body 13 as a support installation surface to ensure the bottom installation accuracy.

[0033] In this embodiment, a secondary grouting layer 4 is formed at the lower end of the column bottom sealing plate to ensure the overall performance of the construction.
