Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of core tube suspension structures, and particularly relates to a self-damping (vibration) inverted conical multi-section core tube suspension structure system. Background Art
[0002] The suspension structure is a structure with excellent seismic performance. Some suspension structures have emerged abroad, and most of the suspension structures adopt the core tube suspension structure system.
[0003] A typical core tube suspension structure consists of a core tube, a suspension transfer floor, suspenders, and suspended floors. As a new system in the suspension building structure system, the core tube suspension vibration reduction structure system has each suspended floor segment acting like a huge mass block, forming a large tuned mass system together with the core tube. Under the action of an earthquake, this structure system has excellent tuned vibration reduction function. The core tube suspension damping system can effectively solve the vibration reduction problem under the action of earthquake loads. However, due to the relatively small stiffness of the suspended part of the core tube suspension structure, the influence of wind vibration is significant. Summary of the Utility Model
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an inverted conical multi-section core tube suspension structure system, which solves the problem that the traditional core tube suspension structure is greatly affected by wind loads due to its relatively small stiffness.
[0005] To achieve the purpose of the utility model, a self-damping inverted conical multi-section core tube suspension structure system provided by the utility model includes multi-section suspension structures, and each section of the suspension structure includes a core tube, a suspension transfer layer, suspenders, and multiple layers of suspended floors;
[0006] The suspension transfer layer is connected to the core tube;
[0007] The top end of the suspender is hinged to the suspension transfer layer;
[0008] The multiple layers of suspended floors are suspended below the suspension transfer layer. The inner side of each layer of suspended floor is connected to the core tube, and the outer side is connected to the corresponding position of the suspender. The bottom end of the suspender inclines towards the core tube, and the area of the multiple layers of suspended floors gradually decreases from top to bottom, so that the elevation of the suspension structure is in an inverted conical shape; the suspended floor is connected to the suspension transfer layer through the inclined suspenders, and the suspenders transfer the floor load to the suspension transfer layer of the structure through the suspenders on the outer side of the suspended floor.
[0009] Specifically, the core tube suspension structure system adopts a multi-section suspension structure for the suspension node layer and the suspended floors below it, such as Figure 1, including a first suspension structure, a second suspension structure and an nth suspension structure. By setting up a building structure with multiple sections of suspension, multi-level frequency modulation can be achieved, making the shock absorption performance of the overall structure better than that of a single-section core tube suspension structure. From the perspective of architectural aesthetic design, the tapered multi-section core tube suspension structure system makes the space of the suspension floor more open, enhancing the overall aesthetics and the sense of hierarchy of the building facade. Moreover, by setting inclined suspenders in the suspension structure part, it is beneficial to change the building structure facade from a rectangle with poor wind resistance to a cone with better wind resistance.
[0010] Further, the concrete steel beam or truss of the suspension conversion layer is connected to one end of the cantilever corbel of the core tube. The inner side of the suspension floor is directly supported on the corbel extended from the core tube.
[0011] Further, the suspenders are connected by a circumferential steel beam and are connected to the extended corbels of the core tube through the steel beam, forming a steel frame of the suspension floor.
[0012] Further, the cross-section of the suspension floor is polygonal.
[0013] Further, the cross-section shape of the suspender adopts a circular shape, a square shape or a rectangular shape.
[0014] Further, the form of the suspender can be a steel suspender or a post-tensioned prestressed concrete suspender.
[0015] A hinge connection is set between the suspender and the suspension conversion layer. Preferably, if it is a post-tensioned prestressed concrete suspender, a flared hole is left on the suspension conversion layer to enable the suspender to swing freely, and a spring and a rubber pad are placed between them.
[0016] Further, a rigid connection is provided between the core tube and the suspension conversion layer.
[0017] Further, a rigid connection is provided between the suspender and the suspension floor.
[0018] Further, a flexible connection is provided between the suspension floor and the core tube.
[0019] Further, a ring beam is provided on the outer circle of each suspension floor. The ring beam is provided at the outer edge of each suspension floor to ensure the overall rigidity of the floor. Setting the ring beam and the suspender on the outer circle of the floor can make the load almost all transfer upward.
[0020] Further, the suspenders of each suspension floor are symmetrically arranged with the center of the core tube as the center of symmetry. The floor load is transferred to the suspension conversion layer, and the rest of the load is directly transferred to the tube body. The force transmission path is simple and the construction difficulty is reduced.
[0021] Further, the inclination angle of the suspender is 72° to 90°
[0022] Furthermore, elastic materials (such as rubber cushions, elastic bearings, etc.) are used between the suspended floor and the core tube to achieve flexible connection, so that while maintaining the connection between the floor slab and the core tube, certain deformation capacity can be provided, the restraint effect can be reduced, and the safety of the connection components and the swing energy dissipation of the suspended part can be ensured.
[0023] Furthermore, the inner ring floor beams of the suspended floor are placed on the small cantilevers protruding from the outer wall of the core tube, and flexible sliding can occur between them, ensuring the safety of the connection components and the swing energy dissipation of the suspended part.
[0024] Furthermore, the cross-section of the core tube is polygonal, and preferably, it is arranged in an axisymmetric form.
[0025] Furthermore, the suspended parts are symmetrically arranged.
[0026] Furthermore, the suspended transfer layer and the multiple suspended floors below it are arranged in sections.
[0027] The number of floors in the suspended floor section is related to factors such as the overhanging length of the transfer layer and the designed floor load. Considering the shock absorption design, preferably, the single-section suspended structure is set to be below 10 floors.
[0028] Furthermore, the suspended transfer beam can adopt a composite beam, a steel reinforced concrete beam, or a prestressed concrete beam, and the cross-section shape is rectangular or lattice type.
[0029] The utility model has at least the following beneficial effects compared with the prior art:
[0030] (1) In the inverted conical multi-section core tube suspended structure system of the utility model, compared with the traditional core tube suspended structure, in this application, the vertically hanging suspender is changed to a suspender with an inclined angle, and the cross-section of the suspended layer can be set as a polygon according to the actual needs of the building, so that the facade of the building changes from a rectangle to a cone with better wind resistance, reducing the influence of the suspended structure with smaller stiffness under the action of wind load.
[0031] (2) For the suspended node layer and the suspended floors below it in the core tube suspended structure system provided by the utility model, multi-section suspension is adopted. The multi-section suspended building structure can adopt multi-stage frequency modulation, so that the shock absorption performance of the overall structure is better than that of the single-section core tube suspended structure, and the visual openness of the suspended transfer layer is greatly improved, and the building shape is more unique than the traditional core tube suspended structure.

[0041] Embodiment 1
[0042] Please refer to Figures 1 to 3 , a conical multi-section core tube suspension structure system provided by the present utility model includes a multi-section suspension structure, and each section of the suspension structure includes a core tube 4, a suspension conversion layer 5, a suspender 6, and multiple suspended floors;
[0043] The suspension conversion layer 5 is connected to the core tube 4;
[0044] The top end of the suspender 6 is hinged to the suspension conversion layer 5;
[0045] Multiple suspended floors are suspended below the suspension conversion layer 5. The inner side of each suspended floor is connected to the core tube 4, and the outer side is connected to the corresponding position of the suspender 6. The bottom end of the suspender 6 inclines towards the core tube 4, and the area of the multiple suspended floors gradually decreases from top to bottom, so that the elevation of the suspension structure is conical.
[0046] Among them, the inclination angle of the suspender 6 is 72° - 90°.
[0047] Compared with the traditional core tube suspension structure, in the conical multi-section core tube suspension structure system provided by this embodiment, in the present application, the vertically hanging suspenders are changed to inclined suspenders, which is beneficial to changing the elevation of the building from a rectangle with poor wind resistance to a cone with better wind resistance, and also enables the cross-section of the suspended floor to be flexibly arranged as a polygon. By tapering and chamfering the building structure, the influence of cross-wind vortex-induced resonance on the suspension structure with relatively small stiffness is reduced, and the wind resistance of the suspension structure is increased. This core tube suspension structure system adopts multi-section suspension for the suspension node layer and the suspended floors below it. The multi-section suspended building structure can adopt multi-stage frequency modulation, so that the shock absorption performance of the overall structure is better than that of a single-section core tube suspension structure. And it greatly improves the field of vision openness of the suspension conversion layer, and the building shape is more unique than the traditional core tube suspension structure.
[0048] Embodiment 2
[0049] Please refer to Figures 1 - 3 , a conical multi-segment core tube suspension structure system provided in this embodiment includes multi-segment suspension structures. Each segment of the suspension structure includes a core tube 4, a suspension conversion layer 5, a suspension rod 6 with a suspension angle, and multiple layers of suspended floors. The suspension angle of the suspension rod should be such that the multiple layers of suspended floors include a first suspended floor 7, a second suspended floor 8,..., and an nth suspended floor 9.
[0050] As Figure 3 shown, the core tube 4 adopts a core tube suspension system. Suspension conversion beams 10 are respectively provided on the east, west, south, and north sides of the core tube 4 and protrude out to form the suspension conversion layer 5. A rigid connection is set between the core tube 4 and the suspension conversion layer 5.
[0051] As Figure 1 shown, the suspension conversion layer 5 suspends n layers of suspended floors, defined as the first suspended floor 7, the third suspended floor 8,..., and the nth suspended floor 9. The suspended floors are suspended below the suspension conversion beam 10 through the suspension rod 6 with a suspension angle. A hinged connection is set between the suspension rod 6 and the suspension conversion layer 5, and a rigid connection is set between the suspension rod 6 and the suspended floors. The area range of the floors gradually increases from bottom to top, and the formed suspension structure system is in an inverted trapezoid shape.
[0052] In this embodiment, as Figure 1 shown, the suspension rod 6 with a suspension angle of the first suspended floor 7, the third suspended floor 8, and the nth suspended floor 9 is provided in a full length and is continuous between the suspension conversion layer 5 and the last layer of the suspended floor.
[0053] In this embodiment, the concrete steel beam of the suspension conversion layer 5 is connected to one end of the corbel protruding from the core tube structure, and the other end is connected to the suspension rod 6 with an inclined angle.
[0054] In this embodiment, the suspension rods 6 with inclined angles are connected by circumferential steel beams and are connected to the corbels protruding from the core tube through the steel beams to form a steel frame of the suspended floor. Due to the flexible setting of the suspension rods, the cross-section of the suspended floor can be designed into a polygonal cross-section. A flexible connection is provided between the floor and the core tube.
[0055] Embodiment 3
[0056] Please refer to Figures 1 to 3 , a conical multi-segment core tube suspension structure system provided by the present utility model includes multi-segment suspension structures. Each segment of the suspension structure includes a core tube 4, a suspension conversion layer 5, a suspension rod 6, and multiple layers of suspended floors;
[0057] The suspension conversion layer 5 is connected to the core tube 4;
[0058] The top end of the suspension rod 6 is hinged to the suspension conversion layer 5;
[0059] Multiple suspended floors are suspended below the suspension conversion layer 5. The inner side of each suspended floor is connected to the core tube 4, and the outer side is connected to the corresponding position of the suspension rod 6. The bottom end of the suspension rod 6 inclines towards the core tube 4. The area of the multiple suspended floors gradually decreases from top to bottom, so that the elevation of the suspension structure is in an inverted cone shape.
[0060] In this embodiment, as Figure 1 shown, considering factors such as the size and distribution of the suspended mass and construction convenience, the core tube suspension structure is designed as a multi-segment suspension structure. This embodiment is a three-segment suspension, and each suspended floor has 5 layers.
[0061] In this embodiment, the suspension rods 6 are connected by steel beams, and in each layer, the corresponding position of the suspension rod 6 and the core tube 4 are connected by steel beams. The connection between the suspended floor and the core tube 4 is a flexible connection. A spring device (or a rubber cushion layer, an elastic support, etc.) can be arranged between the suspended floor and the core tube 4, so that the two can perform flexible sliding. While maintaining the connection between the suspended floor and the core tube, it can provide a certain deformation ability and reduce the restraint effect.
[0062] Generally, the cross-section of a super high-rise building with a core tube suspension structure system is rectangular, and its wind load is larger than that of a special-shaped cross-section (such as a chamfered cross-section, a concave corner, etc.). The main reason is that when the wind acts on a super high-rise building with a standard cross-section, the vortex shedding shows a certain regularity. When the vortex shedding frequency is close to the structural natural vibration period, it is easy to cause cross-wind vortex-induced resonance. The suspension structure system provided by the foregoing embodiments of the present utility model is beneficial to changing the building structure elevation from a rectangle with poor wind resistance to a cone with better wind resistance by arranging inclined suspension rods 6 in the suspension structure part. And because the inclined suspension rods can be flexibly arranged, the cross-section of the suspended layer can adopt a polygon, so each suspended floor is in a polygon cone shape. The traditional super high-rise building structure has a square cross-section column body, and the core tube suspension system proposed by the foregoing embodiments of the present utility model is a polygon cone, which performs taperization and chamfering on the traditional super high-rise building structure, effectively reducing the wind load received by the traditional core tube suspension structure.
[0063] In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
[0064] As described above, the present utility model can be better realized. The above embodiments are only the preferred embodiments of the present utility model and are not used to limit the implementation scope of the present utility model; that is, all equivalent changes and modifications made according to the content of the present utility model are covered by the scope required to be protected by the claims of the present utility model.
