Description

Technical Field

[0001] This invention relates to the technical field of waist trusses for super high-rise buildings, specifically to a waist truss and outrigger truss node structure for super high-rise buildings. Background Technology

[0002] In super high-rise structures, horizontal wind loads or seismic forces often become the controlling factors in the design. Therefore, it is necessary to set up waist trusses and outrigger truss reinforcement layers to solve the problem of insufficient lateral deformation capacity and lateral stiffness of the building structure. However, the existing waist trusses and outrigger trusses of super high-rise buildings still have certain defects in use. In use, the waist truss generally uses the outer frame beams of the upper and lower floors as truss chords, and the web members are in the form of diagonal web members. Due to the presence of diagonal web members, the stress at the end nodes of the truss becomes complex, which makes the overall concrete pouring difficult and reduces the overall construction efficiency.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number 202121134531.1, application date 2021-05-25) provides a truss structure for super high-rise buildings, including an upper frame beam located on the upper floor, a lower frame beam located on the lower floor, and a first frame column and a second frame column set on the outside of the structure. It includes a truss straight web member, a parallel frame beam, the truss straight web member being perpendicular to the lower frame beam, one end of the truss straight web member being fixedly connected to the lower frame beam, the other end of the truss straight web member being fixedly connected to the upper frame beam, the parallel frame beam being perpendicular to the first frame column, one end of the parallel frame beam being fixedly connected to the lower frame beam, one middle end of the parallel frame beam being fixedly connected to the truss straight web member, and the other end of the parallel frame beam being fixedly connected to the upper frame beam.

[0004] While existing technologies can simplify stress conditions, the use of truss straight web members and parallel frame beams arranged only vertically or horizontally, along with frame beams and frame columns forming a waist truss structure, requires high precision in overall design and installation. This makes the overall construction process complex and time-consuming. When the overall structure is subjected to diagonal stress, the web members may bend, affecting the overall stability. Furthermore, the horizontal and vertical arrangement makes the overall connection points relatively weak, affecting the safety of the overall structure. To address these issues, there is an urgent need for innovative designs based on the existing waist truss and outrigger truss node structures for super high-rise buildings. Therefore, we propose a waist truss and outrigger truss node structure for super high-rise buildings that can effectively solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a structure for the waist truss and outrigger truss nodes of a super high-rise building, in order to solve the problems mentioned in the background art. Currently available structures on the market use truss straight web members and parallel frame beams arranged only vertically or horizontally, and frame beams and frame columns to form waist trusses. Therefore, the overall design and installation require high precision, making the overall construction process complex and time-consuming. When the overall structure is subjected to diagonal stress, the web members may bend, thus affecting the overall stability. Furthermore, the horizontal and vertical arrangement makes the overall connection relatively weak, affecting the safety of the overall structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a structural design for a waist truss and outrigger truss node in a super high-rise building, comprising a frame column, a frame beam at the side end of the frame column, a threaded groove on the frame column adapted to a fixing bolt, an elastic plate sleeved on the outside of the fixing bolt, the fixing bolt penetrating the frame beam and connected inside the threaded groove, a support plate inside the frame beam, and a diagonal truss welded to the frame beam via welding plates, the diagonal trusses being arranged in a crisscross pattern, and an outrigger truss body connected to the side end of the frame column via an inclined plate, thereby installing the frame column in the required position, thus ensuring the accurate positioning of the building's vertical structure and providing a stable foundation for subsequent construction and installation. This design reduces the inconvenience of installation that could increase construction time. The frame beams are installed on the frame columns using a combination of fixing bolts and threaded grooves. Because elastic plates are installed on the outside of the fixing bolts, they help balance and evenly distribute the load, effectively preventing localized stress concentration caused by uneven load distribution and enhancing the reliability of the beam-column joints. Furthermore, the internal support plates of the frame beams significantly improve overall support stability, enhancing the load-bearing capacity and deformation resistance of the horizontal structure. The overall structure is stable, reducing the bending problem of the web members under diagonal stress and improving overall stability. The cantilever truss body is connected to the side ends of the frame columns via inclined plates, strengthening the connection between the horizontal and diagonal structures.

[0007] Preferably, the inclined truss is provided with a welding assembly, which includes a support member installed inside the inclined truss. The support member is provided with a node plate, which is welded inside a snap-fit ​​groove. The node plate is welded to the side end of the frame column. The support member is inserted into the inclined truss, and the node plate is snapped in through the snap-fit ​​groove. The overall connection is welded, which improves the safety of the overall structure. Welding plates are used to weld the frame beam to the inclined truss, so that a rigid connection is formed between the frame beam and the inclined truss, which enhances the spatial stability of the structure. It can effectively transfer and distribute horizontal and vertical loads between the frame beam and the inclined truss, improve the seismic and wind resistance of the entire structural system, and enhance the spatial stress performance of the structure.

[0008] Preferably, a support assembly is provided at the bottom of the frame column. The support assembly includes a support seat installed at the bottom of the frame column. A seismic isolation seat is provided at the bottom of the support seat. The seismic isolation seat under the support seat can reduce the impact of seismic loads on the structure, ensure node stability, and effectively improve the safety of the building under seismic action.

[0009] Preferably, the support base has a pouring groove on its side and a first cavity inside, which is connected to the pouring groove. Supporting steel bars are provided inside the first cavity in a staggered arrangement. Concrete is poured into the first cavity through the pouring groove on the side of the support base, which facilitates the concrete and the supporting steel bars to work together to provide stable support. The staggered arrangement of the supporting steel bars facilitates stable support and enhances the load-bearing capacity of the support base.

[0010] Preferably, the frame column has a second cavity inside, and an inclined block is installed inside the second cavity. The inclined block not only effectively improves the shear resistance of the frame column, but also optimizes the load transfer path from the upper structure to the lower column, which helps to reduce local stress concentration and improve the stability of the overall structure.

[0011] Preferably, the cantilever truss body has a first storage slot inside, a limit post is connected through the first storage slot, and an eccentric wheel is sleeved on the outside of the limit post.

[0012] Preferably, the first storage slot is provided with an auxiliary component, which includes a limiting block installed inside the first storage slot. A moving rod is connected through the limiting block. After the limiting post passes through the inclined plate, it rotates inside the first storage slot, causing the eccentric wheel on the outside of the limiting post to rotate. After the eccentric wheel rotates, it contacts the first moving plate, causing the first moving plate to drive the moving rod to move inside the limiting block. The first spring on the outside of the moving rod is convenient for rebound during later disassembly, making overall maintenance convenient.

[0013] Preferably, a first spring is sleeved on the outer side of the moving rod, and a first moving plate is provided at one end of the moving rod, the first moving plate being in contact with the rotated eccentric wheel.

[0014] Preferably, the other end of the movable rod is provided with a rotating plate. The rotating plate is connected to the inside of the second storage slot through a rotating seat. The second storage slot is opened inside the frame column. After the rotating plate rotates, it contacts the second movable plate. A screw is provided on the side end of the second movable plate. A second spring is sleeved on the outside of the screw. The movable rod presses the rotating plate inside the second storage slot, causing the rotating plate to rotate inside the second storage slot through the rotating seat. The other end of the rotating plate moves the second movable plate, so that the screw on the side end of the second movable plate passes through the through hole on the inclined plate. The second spring on the outside of the screw facilitates rebound during later disassembly. The screw is connected to the nut, so that the inclined plate is connected to the frame column and the cantilever truss body. This not only ensures that the three can work together to jointly bear and transmit loads, improving the stability and integrity of the entire structure, but also facilitates disassembly and maintenance.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the joint structure of the waist truss and outrigger truss of the super high-rise building, and the support plates inside the frame beams greatly improve the overall support stability, enhance the load-bearing capacity and deformation resistance of the horizontal structure, and use welding plates to weld the frame beams to the diagonal trusses improve the spatial stress performance of the structure, making the overall structure stable, reducing the bending problem of the web members under diagonal stress, and improving the overall stability. The specific details are as follows:

[0016] (1) The support plates inside the frame beam greatly improve the overall support stability, enhance the load-bearing capacity and deformation resistance of the horizontal structure, and use welding plates to weld the frame beam to the inclined truss, which improves the spatial stress performance of the structure and reduces the bending problem when the web members are subjected to oblique stress.

[0017] (2) The seismic isolation seat under the support can reduce the impact of seismic load on the structure, ensure the stability of the nodes, and effectively improve the safety of the building under seismic action. The concrete and the supporting steel bars work together to provide stable support and enhance the bearing capacity of the support seat.

[0018] (3) An inclined block is installed inside the second cavity of the frame column. The inclined block can not only effectively improve the shear resistance of the frame column, but also optimize the load transfer path from the upper structure to the lower column, thus improving the overall stability of the structure.

[0019] (4) After the limiting post of the auxiliary component passes through the inclined plate, it rotates inside the first storage slot, so that the eccentric wheel on the outside of the limiting post rotates. After the eccentric wheel rotates, it contacts the first moving plate. The overall structure is simple, which is convenient for later maintenance and reduces the problem of increased cost due to complex structure.

[0020] (5) The screw at the side end of the second movable plate passes through the through hole on the inclined plate and connects the screw with the nut, so that the inclined plate is connected to the frame column and the cantilever truss body. The overall connection is not only stable and reliable, but also convenient for disassembly and maintenance, thus improving the overall service life. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: In this example, to improve overall stability, a diagonal truss 8 is used. Its purpose is to reduce bending of the web members under diagonal stress, such as... Figures 1-5 The technical solution shown includes a frame column 1, a frame beam 3 at one side of the frame column 1, a threaded groove 2 on the frame column 1 that is compatible with a fixing bolt 4, an elastic plate 5 on the outside of the fixing bolt 4, the fixing bolt 4 passing through the frame beam 3 and connected inside the threaded groove 2, a support plate 6 inside the frame beam 3, and a diagonal truss 8 welded to the frame beam 3 via welding plates 7, the diagonal trusses 8 being arranged in a crisscross pattern, an outrigger truss body 13 connected to the side of the frame column 1 via an inclined plate 12, and welding components on the diagonal trusses 8. The component includes a support member 9 installed inside the inclined truss 8. A node plate 11 is provided on the support member 9, and the node plate 11 is welded inside the snap-fit ​​groove 10. The node plate 11 is welded to the side end of the frame column 1. During the installation of the super high-rise building, the frame column 1 is installed in the required position, thereby ensuring the accurate positioning of the building's vertical structure, providing a stable foundation for subsequent construction and installation, reducing the problem of increased construction time due to installation inconvenience. The frame beam 3 is installed on the frame column 1 using the cooperation of fixing bolts 4 and threaded grooves 2. Due to the outer side of the fixing bolts 4... The installation of elastic plates 5 helps to balance and evenly transfer loads, effectively avoiding local stress concentration caused by uneven load distribution, enhancing the reliability of beam-column joints. Furthermore, the support plates 6 inside the frame beam 3 significantly improve overall support stability, enhancing the load-bearing capacity and deformation resistance of the horizontal structure. Support members 9 are inserted into the diagonal truss 8, and the node plate 11 is inserted through the snap-fit ​​groove 10. Welding is then performed at the overall connection, improving the overall structural safety. Welding plates 7 are used to weld the frame beam 3 to the diagonal truss 8, forming a rigid connection between them, enhancing the spatial stability of the structure. This effectively transfers and distributes horizontal and vertical loads between the frame beam 3 and the diagonal truss 8, improving the seismic and wind resistance of the entire structural system, enhancing the spatial stress performance of the structure, and increasing overall structural stability. It also reduces the bending problem of the web members under diagonal stress, improving overall stability. The side ends of the frame column 1 are connected to the outrigger truss body 13 through inclined plates 12, strengthening the connection between the horizontal and diagonal structures.

[0034] Example 2: In this example, to improve overall safety, a support component is used. The purpose is to reduce the safety degradation caused by localized stress concentration. Specifically, as follows... Figure 1 and Figures 6-8 As shown, a support assembly is provided at the bottom of the frame column 1. The support assembly includes a support base 14 installed at the bottom of the frame column 1, a seismic isolation seat 15 at the bottom of the support base 14, a casting groove 16 at the side end of the support base 14, a first cavity 17 inside the support base 14, the first cavity 17 being connected to the casting groove 16, and supporting steel bars 18 arranged in a staggered pattern inside the first cavity 17. A second cavity 19 is provided inside the frame column 1, and an inclined block 20 is installed inside the second cavity 19. The support base 14 at the bottom of the frame column 1 facilitates support and disperses the pressure at the bottom of the frame column 1. The seismic isolation seat 15 under the support base 14 can reduce seismic load. The impact on the structure ensures the stability of the nodes and effectively improves the safety of the building under seismic action. Concrete is poured into the first cavity 17 through the pouring groove 16 on the side of the support seat 14, which facilitates the concrete to cooperate with the supporting steel bars 18 for stable support. The staggered supporting steel bars 18 facilitate stable support and enhance the load-bearing capacity of the support seat 14. The second cavity 19 of the frame column 1 is provided with an inclined block 20. The inclined block 20 can not only effectively improve the shear resistance of the frame column 1, but also optimize the load transfer path from the upper structure to the lower column, which helps to reduce the phenomenon of local stress concentration and improve the stability of the overall structure.

[0035] Example 3: In this example, the inclined plate 12 is connected to the frame column 1 and the outrigger truss body 13. The overall connection is not only stable and reliable, but also convenient for disassembly and maintenance. Specifically, as shown below...

A moving rod 25 is connected through the limiting block 26. A first spring 27 is sleeved on the outside of the moving rod 25. A first moving plate 24 is provided at one end of the moving rod 25, and the first moving plate 24 contacts the rotated eccentric wheel 23. A rotating plate 28 is provided at the other end of the moving rod 25. The rotating plate 28 is connected to the inside of a second storage slot 30 via a rotating seat 29. The second storage slot 30 is located inside the frame column 1. After the rotating plate 28 rotates, it contacts the second moving plate 31. A screw 32 is provided on the side end of the second moving plate 31, and a second spring 33 is sleeved on the outside of the screw 32. The limiting post 22 rotates inside the first storage slot 21 after passing through the inclined plate 12. The eccentric wheel 23 on the outside of the limiting column 22 rotates, and after rotating, the eccentric wheel 23 contacts the first moving plate 24, causing the first moving plate 24 to drive the moving rod 25 to move inside the limiting block 26. The first spring 27 on the outside of the moving rod 25 facilitates rebound during disassembly, making overall maintenance convenient. The moving rod 25 presses the rotating plate 28 inside the second storage slot 30, causing the rotating plate 28 to rotate inside the second storage slot 30 via the rotating seat 29. The other end of the rotating plate 28 moves the second moving plate 31, causing the screw 32 on the side of the second moving plate 31 to pass through the through hole on the inclined plate 12.
