Description

Technical Field

[0001] The present invention relates to the technical field of building structures, and particularly to a super high-rise flat tube structure system. Background Art

[0002] With the continuous development of high-rise and super high-rise buildings, more and more high-rise buildings emerge in the central areas of cities. The requirements for the lateral stiffness of the building structure system are also getting higher and higher. Especially in strong earthquake areas and strong wind areas along the coast, the requirements for the stiffness of the structure system are even higher. Traditional lateral force resisting structural forms such as frame structure systems, frame-shear wall structure systems, frame-core tube structure systems, etc. can no longer meet the building space requirements of modern high-rise buildings. Seeking new lateral force resisting structural system forms has become a key concern for engineering designers. Currently, the more widely applied high-rise structural system is the frame-core tube structure system, which refers to a structural system composed of a frame system formed by peripheral beam-columns and a core tube.

[0003] The existing frame-core tube structure system generally means that there is one core tube, which is located at the center of the high-rise building and is surrounded by shear walls and coupling beams. Its main building functions are vertical transportation and equipment rooms. The frame structure is distributed along the circumference of the core tube on the outside of the core tube and is mainly the building functional area. The core tube is mainly used to resist horizontal lateral forces, and the frame structure cooperates with the core tube to provide the lateral and torsional stiffness of the structure. When the aspect ratio or height-width ratio of the building is relatively large, the existing frame-core tube structure cannot provide sufficient lateral stiffness. Therefore, the existing frame-core tube structure system is not suitable for buildings with relatively large aspect ratios or height-width ratios, especially buildings located in strong earthquake and strong wind areas; in addition, as the number of floors increases, the proportion of the horizontal load acting on the building borne by the core tube becomes larger. That is to say, the increase in the number of building floors makes the weight and occupied space of the core tube increase, resulting in a reduction in the available area of the building. Summary of the Invention

[0004] The purpose of the present invention is to provide a super high-rise flat tube structure system that is suitable for buildings with relatively large aspect ratios or height-width ratios, has strong lateral force resistance, and a large available area.

[0005] To achieve the above purpose, the present invention provides a super high-rise flat tube structure system, which includes shear walls, coupling beams, a first frame structure, and multiple trusses. The shear walls and the coupling beams are both provided in multiple numbers. Multiple shear walls and multiple coupling beams are connected and enclose a flat and long-shaped flat tube. Two flat tubes are provided and are arranged opposite to each other along their long sides. The first frame structure is disposed between the two flat tubes and connects them. Multiple trusses are arranged along the length direction of the flat tube and are connected between the two flat tubes.

[0006] In some embodiments of the present application, the cross-sections of the two flat tubes are both rectangular, and the long sides thereof are arranged in parallel.

[0007] In some embodiments of the present application, the height-width ratio of the flat tube is 30 to 100.

[0008] In some embodiments of the present application, some or all of the shear walls protrude from the flat tube in the width direction of the flat tube to form wall supports, and both ends of each truss are respectively connected between the wall supports of the two flat tubes.

[0009] In some embodiments of the present application, the truss includes two chord members and a plurality of diagonal web members disposed between the two chord members, and both ends of each chord member are respectively connected to the wall supports of the two flat tubes.

[0010] In some embodiments of the present application, a plurality of the trusses form a truss layer, and a plurality of the truss layers are arranged in the height direction of the flat tube.

[0011] In some embodiments of the present application, the first frame structure includes a plurality of first frame beams and a plurality of first secondary beams. The first frame beams are disposed between the two flat tubes and connect them. The first secondary beams are arranged alternately with the first frame beams, and the first secondary beams are connected between two of the first frame beams.

[0012] In some embodiments of the present application, the first frame structure further includes a plurality of first frame columns. The plurality of first frame columns are vertically disposed at positions close to the middle of the super high-rise flat tube structure system. The first frame columns are connected to the flat tubes, between any two adjacent first frame columns, and between the two flat tubes through the first frame beams.

[0013] In some embodiments of the present application, a second frame structure is further included. The second frame structure includes a plurality of second frame beams and a plurality of second secondary beams. The second frame beams are disposed on the outer side walls of the two flat tubes facing away from each other and extend in a direction away from the flat tubes. The second secondary beams are arranged alternately with the second frame beams, and the second secondary beams are connected between two of the second frame beams.

[0014] In some embodiments of the present application, the second frame structure further includes a plurality of second frame columns. The second frame columns are vertically disposed at the two side edges of the super high-rise flat tube structure system. The second frame columns are connected to the flat tubes and between any two adjacent second frame columns through the second frame beams.

[0015] In some embodiments of the present application, the span between the two core tubes is 8 to 50 m.

[0016] The present invention provides a super high-rise flat tube structure system. Compared with the prior art, its beneficial effects are as follows:

[0017] The super high-rise flat tube structure system provided by the present invention includes shear walls, coupling beams, a first frame structure, and multiple trusses. Both the shear walls and the coupling beams are provided in multiple numbers. Multiple shear walls and multiple coupling beams are connected and enclose a flat and long-shaped flat tube. Two flat tubes are provided and are arranged opposite to each other along their long sides. The first frame structure is arranged between the two flat tubes and connects them. Multiple trusses are arranged along the length direction of the flat tube and are connected between the two flat tubes. Based on the above structure, the flat tubes are used to bear loads and resist horizontal lateral forces. Compared with the single core tube in the prior art, the flat tubes of the present super high-rise flat tube structure system are set to be flat and long-shaped and two in number. When building a building with a large aspect ratio of length to width or height to width, the setting form of the two flat and long-shaped flat tubes and the first frame structure erected between them is more stable than the existing frame structure extending circumferentially along the core tube. The increase in the span of the first frame structure has a smaller impact on the lateral force resistance. The two relatively arranged flat tubes have stronger lateral force resistance than the single core tube, so it is applicable to buildings with a large aspect ratio of length to width or height to width. The aspect ratio of a building adopting the existing frame-core tube structure system with a single core tube is generally only 8-12, while the aspect ratio of a building adopting the present super high-rise flat tube structure system can reach 15-20. Especially in areas with strong earthquakes and strong winds, the building adopting the present super high-rise flat tube structure system can meet the requirements of the building for lateral stiffness. Secondly, multiple trusses can transfer lateral forces between the two flat tubes, enabling the two flat tubes to resist horizontal lateral forces synergistically, thereby improving the lateral stiffness of the super high-rise flat tube structure system. In addition, both of the two flat tubes are flat and long-shaped, and the first frame structure arranged between them can provide a large space area, increasing the available floor area. That is, the available area of a building adopting this structure system is larger than that of a building adopting the existing frame-core tube structure system and is more practical.

[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0023] It should be understood that in the description of the present application, the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application. The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. That is, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In addition, unless otherwise specified, the meaning of "plurality" is two or more.

[0024] It should be noted that in the description of the present application, unless otherwise clearly defined and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0025] It should be emphasized that the above-mentioned flat tube 1 refers to a flat and long cylindrical structure surrounded by a shear wall and a coupling beam, and is used to bear loads and resist horizontal lateral forces.

[0026] Such as Figure 1 and Figure 3As shown in the figure, an embodiment of the present invention provides a super high-rise flat tube structure system, which includes shear walls 11, coupling beams 12, a first frame structure 2, and multiple trusses 4. Both the shear walls 11 and the coupling beams 12 are provided in multiple numbers. Multiple shear walls 11 and multiple coupling beams 12 are connected and enclose a flat and long flat tube 1. Two flat tubes 1 are provided and are arranged opposite to each other along their long sides. The first frame structure 2 is arranged between the two flat tubes 1 and connects them. Multiple trusses 4 are arranged along the length direction of the flat tube 1 and are connected between the two flat tubes 1. Specifically, a reinforced concrete beam-slab system is used for construction inside the flat tube 1, and a steel-concrete composite floor slab system is used outside the flat tube 1. Among them, the composite floor slab uses a steel bar truss 4 type floor formwork.

[0027] Based on the above structure, compared with the single core tube in the prior art, the flat tube 1 of the super high-rise flat tube structure system is set to be flat and long and is provided in two. When a building with a large aspect ratio of length to width or height to width needs to be built, the setting form of the two flat and long flat tubes 1 and the first frame structure 2 erected between them is more stable than the existing frame structure extending circumferentially along the core tube. The increase in the span of the first frame structure 2 has a smaller impact on the lateral stiffness resistance. The two relatively arranged flat tubes 1 have stronger lateral stiffness resistance than the single core tube, so it is applicable to buildings with a large aspect ratio of length to width or height to width. The aspect ratio of a building using the existing frame-core tube structure system of a single core tube is generally only 8-12, while the aspect ratio of a building using the super high-rise flat tube structure system of the present invention can reach 15-20. Especially in areas with strong earthquakes and strong winds, the building using the super high-rise flat tube structure system of the present invention can meet the requirements of the building for lateral stiffness resistance. Secondly, multiple trusses 4 can transfer lateral forces between the two flat tubes 1, so that the two flat tubes 1 can cooperate to resist horizontal lateral forces, thereby improving the lateral stiffness resistance of the super high-rise flat tube structure system; in addition, both of the two flat tubes 1 are flat and long, and the first frame structure 2 arranged between them can provide a large space area, making the available floor area of the floor increase. That is to say, the available floor area of a building using this structure system is larger than that of a building using the existing frame-core tube structure system and is more practical.

[0028] Optionally, as Figure 1 shown, in this embodiment, the first frame structure 2 includes multiple first frame beams 21 and multiple first secondary beams 22. The first frame beams 21 are arranged between the two flat tubes 1 and connect them. The first secondary beams 22 are arranged staggeredly with the first frame beams 21, and the first secondary beams 22 are connected between two first frame beams 21. Specifically, the first frame beams 21 are rigidly connected to the shear walls 11 enclosing the flat tube 1. The first frame beams 21 are arranged along the length direction of the flat tube 1. The first secondary beams 22 are connected between two adjacent first frame beams 21. Based on this, the first frame beams 21 connect the two flat tubes 1 and play a role in earthquake resistance, and the first secondary beams 22 play a role in supporting partition walls.

[0029] Optionally, asFigure 1 As shown in the figure, in this embodiment, the first frame structure 2 further includes a plurality of first frame columns 23. The plurality of first frame columns 23 are vertically arranged near the middle of the super high-rise flat tube structure system. The first frame columns 23 are connected to the flat tube 1, between any two adjacent first frame columns 23, and between the two flat tubes 1 by first frame beams 21. Obviously, the first frame columns 23 are arranged between the two flat tubes 1. It should be understood that whether to add first frame columns 23 can be selected according to the span between the flat tubes 1. If the span is small, the two flat tubes 1 are directly connected by the first frame beam 21. If the span is large, first frame columns 23 are added between the two flat tubes 1. In this way, when the span between the flat tubes 1 is large, setting a plurality of first frame columns 23 can increase the stiffness of the structural system and improve the anti-vibration performance of the structural system. At this time, the available building area between the two flat tubes 1 is further increased, improving the utilization rate of the building area.

[0030] Optionally, as Figure 1 shown, in this embodiment, the super high-rise flat tube structure system further includes a second frame structure 3. The second frame structure 3 includes a plurality of second frame beams 31 and a plurality of secondary beams 32. The second frame beams 31 are arranged on the outer side walls of the two flat tubes 1 facing away from each other and extend in a direction away from the flat tubes 1. The secondary beams 32 are arranged in a staggered manner with the second frame beams 31, and the secondary beams 32 are connected between two second frame beams 31. Specifically, the second frame beams 31 are rigidly connected to the shear walls 11 that enclose the flat tube 1. The second frame beams 31 are arranged along the length direction of the flat tube 1. The secondary beams 32 are connected between two adjacent second frame beams 31. Based on this, the second frame structure 3 further increases the available area of the super high-rise flat tube structure system. The arrangement form of the two flat tubes 1 enables both the first frame mechanism and the second frame structure 3 to further increase the available area of the building on the basis of meeting the lateral stiffness.

[0031] Optionally, as Figure 1 shown, in this embodiment, the second frame structure 3 further includes a plurality of second frame columns 33. The second frame columns 33 are vertically arranged at the two side edges of the super high-rise flat tube structure system. The second frame columns 33 are connected to the flat tube 1 and between any two adjacent second frame columns 33 by second frame beams 31. Specifically, the second frame columns 33 are arranged outside the two flat tubes 1. It should be understood that whether to add second frame columns 33 can be selected according to the span of the second frame beams 31. If the span is small, the second frame columns 33 are not required. If the span is large, second frame columns 33 are added at the end of the second frame beam 31 far from the flat tube 1. In this way, when the span of the second frame beam 31 is large, setting a plurality of second frame columns 33 can increase the stiffness of the structural system and improve the anti-vibration performance of the structural system. At this time, the available building area on the outer sides of the two flat tubes 1 facing away from each other is further increased, improving the utilization rate of the building area.

[0032] Optionally, as Figure 1 shown, the cross-sections of the two flat tubes 1 are both rectangular, and the long sides thereof are arranged in parallel. It should be emphasized that the cross-section of the flat tube 1 can also be approximately rectangular.

[0033] Optionally, as Figures 1 to 3 shown, in this embodiment, some or all of the shear walls 11 protrude from the flat tube 1 along the width direction of the flat tube 1 to form wall supports 13, and both ends of each truss 4 are respectively connected between the wall supports 13 of the two flat tubes 1. In this way, the setting of the wall supports 13 can effectively reduce the structural self-weight inside the flat tube 1 and increase the building flexibility of the flat tube 1. Since the wall supports 13 are added, the width of the flat tube 1 can be reduced while meeting the bearing capacity requirements of the super high-rise flat tube structure system. In addition, the connection between the truss 4 and the wall support 13 is beneficial to the truss 4 to transfer the horizontal lateral force between the two flat tubes 1, so that the two flat tubes 1 can cooperate to resist the lateral force.

[0034] Optionally, as Figure 1 shown, in this embodiment, the height-width ratio of the flat tube 1 is 30 to 100. Preferably, the height-width ratio of the flat tube 1 is 30, 40, 50, 60 or 100. In existing buildings, due to the adoption of a single-core tube structure, on the basis of meeting the requirements of lateral stiffness resistance, the height-width ratio of the core tube can only reach 10 to 20. The higher the building, the larger the width of the core tube must be set, and the available area of the building is smaller. However, the setting form of the two flat tubes 1 in the present invention enables the height-width ratio of the flat tube 1 to reach 30 to 100, saving the material used for the flat tube 1 while meeting the requirements of lateral stiffness resistance and increasing the available area of the building.

[0035] Optionally, as Figure 1 shown, in this embodiment, the span between the two flat tubes 1 is 8 to 50 m. Preferably, the span between the two flat tubes 1 is 10 to 45 m. It should be understood that when a first frame column 23 is provided between the two flat tubes 1, the span between the two flat tubes 1 can be set larger.

[0036] Optionally, as shown in the figure and the figure, in this embodiment, the truss 4 includes two chord members 41 and a plurality of diagonal web members 42 arranged between the two chord members 41, and both ends of each chord member 41 are respectively connected to the wall supports 13 of the two flat tubes 1.

[0037] Optionally, as shown in the figure and the figure, in this embodiment, a plurality of the trusses 4 form a truss layer 5, and a plurality of truss layers 5 are provided. The plurality of truss layers 5 are arranged along the height direction of the flat tube 1. In this way, the plurality of truss layers 5 further increase the lateral stiffness resistance of the structural system and can transfer the horizontal lateral force between the two flat tubes 1 better.

[0038] In summary, the embodiment of the present invention provides a super high-rise flat tube structure system, which mainly consists of shear walls 11, coupling beams 12, a first frame structure 2, and multiple trusses 4. Both the shear walls 11 and the coupling beams 12 are provided in multiple numbers. Multiple shear walls 11 and multiple coupling beams 12 are connected and enclose a flat and long flat tube 1. Two flat tubes 1 are provided and are arranged opposite to each other along their long sides. The first frame structure 2 is arranged between the two flat tubes 1 and connects them. Multiple trusses 4 are arranged along the length direction of the flat tube 1 and are connected between the two flat tubes 1. Compared with the prior art, this super high-rise flat tube structure system has the advantages of being applicable to buildings with a large aspect ratio of length to width or height to width, strong lateral stiffness, and large available area, etc.

[0039] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
