Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a modular structure of staggered stacked steel tube concrete column-composite beam. Background Technology

[0002] Currently, the country is vigorously promoting prefabricated building structures, and the structure formed by steel-concrete composite columns and steel-concrete composite beams is one of the most widely used, combining the advantages of both steel and concrete structures. Modular structural systems are a more advanced form of prefabricated structure. Currently, the main forms of modular structures are steel or concrete structures. Concrete structures require molds and concrete pouring in factories, while steel structures are more expensive. Composite structures, however, combine the advantages of both steel and concrete structures, fully utilizing the tensile strength of steel and the compressive strength of concrete, resulting in significant technical, economic, and social benefits. However, due to the complex connection structure of composite structures, reliable connection nodes are currently lacking. Utility Model Content

[0025] Please see Figure 1As shown, this utility model relates to a modular structure 1 of staggered stacked steel-concrete composite columns and beams. The modular structure 1 is a rectangular frame, comprising steel-concrete composite columns 10, steel beams 20, floor slabs 40, and connecting nodes 30. The steel-concrete composite columns 10 and steel beams 20 are vertically connected at the connecting nodes 30. Every eight steel beams 20 and every four steel-concrete composite columns 10 are connected through the connecting nodes 30 to form a single rectangular frame. Floor slabs 40 are respectively located on the top and bottom surfaces of the rectangular frame. Figure 5 As shown, multiple staggered steel-concrete composite column-beam modular structures are staggered and stacked through connection nodes 30 to form a multi-layer rectangular main structure.

[0026] Combination Figure 2 and Figure 3 As shown, the connecting node 30 includes a connecting plate 31, a C-shaped plug-in block 32, and a C-shaped plug-in cylinder 33. The C-shaped plug-in block 32 and the C-shaped plug-in cylinder 33 are connected to the connecting plate 31. Both ends of the steel-concrete composite column 10 are connected to the connecting plates 31 of the two connecting nodes 30, respectively, and both ends of the steel beam 20 are connected to the C-shaped plug-in cylinders 33 of the two connecting nodes 30, respectively. When the two connecting nodes 30 are plugged in, the C-shaped plug-in block 32 is inserted into the C-shaped plug-in cylinder 33 to form a grouting space. Grouting connects the two connecting nodes 30, thereby achieving the connection of the two composite beam-column modules.

[0027] The connecting node 30 has a dual shear-resistant element, which includes a first stud 34, a second stud 35, and shear-resistant ribs 36. The outer wall of the C-shaped plug block 32 has a first stud 34 extending horizontally outwards, and multiple first studs 35 are arranged in a matrix. The inner wall of the C-shaped plug cylinder 33 has a second stud 35 extending horizontally inwards, and multiple second studs 36 are arranged in multiple matrices. After the two connecting nodes 30 are plugged in, the first studs 34 and second studs 35 are horizontally staggered. The outer wall of the C-shaped plug block 32 is surrounded by multiple rings of shear-resistant ribs 36, and the inner wall of the C-shaped plug cylinder 33 is also surrounded by multiple rings of shear-resistant ribs 36. The shear-resistant ribs 36 are horizontally staggered with the horizontal rows of first studs 34 or second studs 35, or the shear-resistant ribs 36 are arranged around the horizontal rows of first studs 34 or second studs 35. The first stud 34, the second stud 35, and the shear rib 36 enhance the reliability of the connection, enabling the steel-concrete composite column 10 to maintain overall stability even when subjected to torque.

[0028] The steel-concrete composite column 10 includes a concrete column 11 and a steel pipe 12 fitted onto the concrete column 11.

[0029] The steel beam 20 is an I-beam type, comprising an integrally formed vertical plate 22 and two horizontal plates 21. The two horizontal plates 21 are horizontally arranged, and the vertical plate 22 is arranged between the two horizontal plates 21. The floor slab 40 is arranged on the top horizontal plate 21.

[0030] like Figure 4 As shown, floor slab 40 is a concrete slab with embedded reinforcing bars 41 and third shear studs 42. Multiple reinforcing bars 41 intersect perpendicularly and are arranged in a grid pattern, with the third shear studs 42 positioned within the grid formed by the reinforcing bars 41. This design ensures sufficient support strength for floor slab 40 while improving shear resistance.
