Description

Technical Field

[0001] This utility model relates to the field of building structures, and in particular to a steel structure system suitable for super high-rise buildings with an offset core tube. Background Technology

[0002] High-rise buildings typically utilize locations such as elevator shafts and vertical utility shafts to arrange shear walls, forming a core tube that serves as the main lateral force resisting component. This creates a frame-core tube structural system with the core tube in the center and the frames arranged around it. In recent years, offset core tube structures have become increasingly popular among architects and owners due to their superior landscape effects and better orientation.

[0003] For example, the invention disclosed in publication number CN115522636A discloses a super high-rise steel structure system, including a gravity frame structure, an eccentrically supported frame, and a mega-frame and mega-bracing structure. The gravity frame structure is arranged on one side of the mega-frame and mega-bracing structure; the gravity frame structure includes gravity frame columns and gravity frame beams, with gravity frame beams hinged between adjacent gravity frame columns; the mega-frame and mega-bracing structure has an interface connecting to the gravity frame structure, an outer surface deviating from the gravity frame structure, and several mega-columns arranged on the outer surface, with mega-bracing connecting the mega-columns, and the eccentrically supported frame is arranged on the interface.

[0004] However, the aforementioned technology employs a mega-frame-mega-support structure system, with mega-columns distributed around the perimeter of the structure. These large cross-sections present certain construction challenges. Furthermore, the use of strip trusses across multiple floors is detrimental to the building facade design. For ultra-high-rise buildings with an offset core tube, adopting a traditional frame-concrete core tube structure system would introduce a series of technical problems, including significant torsional effects and high tensile stress in the walls. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the existing technology and provide a steel structure system suitable for super high-rise buildings with offset core tubes.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A steel structure system suitable for super high-rise buildings with an offset core tube includes a main structure and a secondary frame structure, wherein the secondary frame structure is offset to one side of the main structure, and the main structure includes diagonal bracing, a steel tube concrete frame and a ring truss.

[0008] The steel-concrete composite frame includes steel-concrete composite frame columns and floor slabs. The floor slabs are horizontally installed on the steel-concrete composite frame columns. The diagonal braces are inclined and fixed between the steel-concrete composite frame columns. The ring trusses are installed around the same floor. The diagonal braces are distributed in a floor-to-floor manner with ring trusses between adjacent floors. The secondary frame structure includes steel frame columns and floor slabs.

[0009] Preferably, there are multiple ring trusses, which are installed in the refuge floors of the super high-rise building.

[0010] Preferably, the diagonal braces are symmetrically distributed on both sides of the steel-concrete composite frame.

[0011] Preferably, the diagonal brace includes a first diagonal brace subunit and a second diagonal brace subunit arranged intersecting each other, and the plane in which the diagonal brace is located is in a vertical plane.

[0012] Preferably, the diagonal brace is a box-type steel support.

[0013] Preferably, the floor assembly includes a horizontal steel beam and a floor slab, wherein the floor slab is fixed to the horizontal steel beam.

[0014] Preferably, the horizontal steel beams on the floor are H-shaped steel beams.

[0015] Preferably, the ring truss includes web members and chord members, and the web members are evenly distributed between the chord members in a triangular structure.

[0016] Preferably, the web members are H-beams or box-shaped steel, and the chord members are H-beams or box-shaped steel.

[0017] Preferably, the steel frame column is a steel column.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] (1) This scheme strengthens the floor components and the steel-concrete composite frame by setting diagonal bracing within the steel-concrete composite frame, and installs a ring truss in the seismic isolation layer of the high-rise building, enabling the main structure to withstand horizontal forces such as seismic action and wind loads. The fully offset secondary frame only bears gravity loads, and the overall structural stress is clear and reasonable, effectively reducing the eccentricity of the structure and realizing the building requirement of separating the vertical transportation system from office, hotel, and commercial functions, which is highly practical.

[0020] (2) In this design, the location of the ring truss is combined with the location of the refuge floor of the high-rise building, and the ring truss is set up on a single floor and does not span multiple floors. Compared with the existing strip trusses that span multiple floors, the ring truss in this design is more advantageous for the building facade layout and has better economic efficiency.

[0021] (3) In this scheme, the steel-concrete composite columns do not distinguish between mega-columns and bending-resistant frame columns. All steel-concrete composite columns have the same cross-section and are conventional steel-concrete composite columns. Compared with the existing scaffolding that distinguishes between mega-columns and bending-resistant frame columns, the consistent structure, combined with other structures, enables the main structure to meet the load-bearing requirements and facilitates overall construction.

[0022] (4) The secondary frame of this scheme only bears gravity load, and the steel column size is small, which has good economic and social benefits. Attached Figure Description

[0039] Example 1

[0040] like Figures 1 to 8 As shown, this embodiment provides a steel structure system suitable for super high-rise buildings with an offset core tube, including a main structure 6 and a secondary frame structure 4. The secondary frame structure 4 is offset to one side of the main structure 6. The main structure 6 includes diagonal bracing 1, steel tube concrete frame 2 and ring truss 3.

[0041] The steel-concrete composite frame 2 includes steel-concrete composite frame columns 21 and floor components 5. The floor components 5 are horizontally installed on the steel-concrete composite frame columns 21. The diagonal braces 1 are inclined and fixed between the steel-concrete composite frame columns 21. The ring truss 3 is installed around the same floor. The diagonal braces 1 are provided with a floor-to-floor distribution of the ring truss 3 between adjacent floors. The secondary frame structure 4 includes steel frame columns 41 and floor components 5.

[0042] By installing diagonal bracing 1 within the steel-concrete composite frame 2, the floor slab components 5 and the steel-concrete composite frame 2 are reinforced. Furthermore, a ring-shaped truss 3 is installed in the seismic isolation layer of the high-rise building, enabling the main structure 6 to withstand horizontal forces such as earthquakes and wind loads. The fully offset secondary frame 4 bears only gravity loads, resulting in a clear and rational overall structural stress distribution. This effectively reduces structural eccentricity, fulfilling the architectural requirement of separating the vertical transportation system from office, hotel, and commercial functions, demonstrating strong practicality.

[0043] Preferred implementation methods, such as Figure 1 , Figure 4 and Figure 8 As shown, there are multiple ring trusses 3, which are installed in the refuge floors of the super high-rise buildings.

[0044] The ring truss is positioned in conjunction with the refuge floor locations of the high-rise building, and it is a single-layer structure that does not span multiple floors. Compared to existing strip trusses that span multiple floors, the ring truss in this design is more advantageous for the building facade layout and offers better economic efficiency.

[0045] In this embodiment, as Figure 1 , Figure 3 and Figure 8 As shown, the diagonal braces 1 are symmetrically distributed on both sides of the steel-concrete composite frame 2. The diagonal braces 1 include a first diagonal brace sub-unit and a second diagonal brace sub-unit that are arranged to cross each other, and the plane in which the diagonal braces 1 are located is in a vertical plane.

[0046] Among them, diagonal brace 1 is a box-shaped steel support.

[0047] In this embodiment, as Figures 5 to 7 As shown, the floor assembly 5 includes a horizontal steel beam 52 and a floor slab 51, with the floor slab 51 fixed to the horizontal steel beam 52. The horizontal steel beam 52 is an H-shaped steel beam.

[0048] In this embodiment, the ring truss 3 includes web members and chord members, with the web members evenly distributed in a triangular structure between the chord members. The web members are H-beams or box-section steel, and the chord members are H-beams or box-section steel.

[0049] In this embodiment, the steel frame column 41 is a steel column.

[0050] In conjunction with the above preferred embodiments, such as Figure 1-8As shown, this embodiment provides a steel structure system specifically applicable to a super high-rise building with a completely offset core tube. This structural system includes diagonal bracing 1, a steel-concrete composite frame 2, ring trusses 3, and secondary frames 4. The secondary frames 4 are completely offset to one side of the main structure 1; the steel-concrete composite frame 2 includes steel-concrete composite frame columns 21 and floor assemblies 5; the floor assemblies 5 include several horizontally arranged floor slabs 51 and horizontal steel beams 5-2 located at the bottom of the floor slabs 52. Multiple ring trusses 3 are arranged in conjunction with building refuge floors; diagonal bracing 1 is installed between adjacent ring trusses 3 at different levels; diagonal bracing 1 is symmetrically arranged on both sides of the main structure 1; the diagonal bracing 1 is a box-type steel support; the horizontal steel beams 52 are H-shaped steel beams.

[0051] In this embodiment, the diagonal brace 1 is a box-section steel, the web members and chords of the ring truss 3 are H-beams or box-section steel, the floor horizontal steel beam 52 is an H-beam, and the secondary frame columns are steel columns. The specific dimensions of the above components can be determined according to the actual stress, and the position and number of the ring truss can be determined according to the actual structural stiffness requirements.

[0052] This utility model enables the separation of vertical transportation systems from office, hotel, and commercial functions. The steel frame-support structure, composed of a ring truss, steel pipe concrete, and diagonal braces, bears horizontal loads such as seismic forces and wind loads, resulting in a very clear and reasonable stress distribution. The secondary frame only bears gravity loads, and the steel columns are small, reducing the amount of steel used in the structure.

[0053] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
