Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated building technology, specifically to an irregularly shaped steel pipe column and a supporting combined shear wall. Background Technology
[0002] In recent years, the vast majority of structures in my country still use reinforced concrete columns. However, research shows that although the overall performance of reinforced concrete columns has improved under various new reinforcement schemes, their overall seismic performance and shear failure are severe. Simply increasing the amount of stirrups and the reinforcement method has limited effect on improving the ductility and shear resistance of coupling beams. Moreover, construction is complex, and the dense reinforcement is not conducive to concrete pouring. As for steel-concrete composite columns, their application is limited, currently only widely used in bridges. When the steel tube wall is thin, internal reinforcement or structural steel is still required, making construction more complex. For steel-concrete composite columns with thicker walls, the ideal combination of steel tube and concrete cannot be achieved. At the same time, the current combination forms of steel-concrete composite columns are still relatively simple, making them difficult to apply when the cross-sectional shape is special, and the restraint effect is not fully realized.
[0003] This case arose from the aforementioned issues. Utility Model Content

[0022] This utility model embodiment provides an irregularly shaped steel pipe column and a supporting combination shear wall, such as Figure 1-5 As shown, it includes irregularly shaped steel pipe columns and frame beams 14, with the frame beams 14 positioned between two adjacent irregularly shaped steel pipe columns. The upper and lower ends of the irregularly shaped steel pipe columns are used to support the floor 15.
[0023] The irregular steel pipe column includes a square column 1 and several U-shaped columns 2. The side of the square column 1 is provided with a web plate 3 for positioning and abutting the two ends of the U-shaped column 2.
[0024] like Figure 2 As shown, square column 1 is made of square steel tube, and U-shaped column 2 has a cross-sectional shape of square steel tube with one side open. The irregular cross-section formed by square column 1 and U-shaped column 2 is with square column 1 as the central section, and U-shaped column 2 is welded to the four webs 3 of square column 1 in a direction perpendicular to the irregular cross-section. The cross-section can be T-shaped, L-shaped, straight, or cross-shaped.
[0025] like Figure 4-5 As shown, the frame beam 14 is one of the following: straight, single-sloping, herringbone, or cross-shaped. In order to connect frame beams 14 with different configurations, the supporting combined shear wall also includes a connecting part for installing the frame beam 14. A connecting plate 4 is provided on the side of the U-shaped column 2. Fixing holes 5 are equally spaced along the length of the connecting plate 4, and the connecting part can be fixed on the connecting plate 4.
[0026] like Figure 3 As shown, the specific connecting parts include a slot 6, a fixing sleeve 7, a fixing seat 8, and a rotating seat 9. The fixing sleeve 7 has screw holes that match the fixing hole 5. The screw holes on the fixing sleeve 7 are installed on the fixing hole 5 by fixing bolts 10. Two connecting plates 4 are provided on each side of the U-shaped column 2, and the fixing sleeve 7 surrounds the connecting plates 4 in a U-shape. By providing two connecting plates 4, the connection strength between the frame beam 14 and the irregular steel pipe column can be increased.
