Description

Technical Field

[0001] The present invention relates to the technical field of waist trusses for super high-rise buildings, and particularly to a node structure of a waist truss and an outrigger truss for a super high-rise building. Background Technique

[0002] In super high-rise structures, horizontal wind loads or seismic actions often become the controlling actions in design. Therefore, waist trusses and outrigger trusses are needed to strengthen the lateral deformation capacity and insufficient lateral stiffness of the building structure. However, there are still certain defects in the existing waist trusses and outrigger trusses of super high-rise buildings. During use, the waist truss generally uses the outer frame beams of the upper and lower floors as the truss chords, and the web members adopt the form of inclined web members. Due to the existence of the inclined web members, the stress at the end nodes of the truss is complex, which makes the overall concrete pouring difficult and reduces the overall construction efficiency.

[0003] In order to overcome the above defects, a structure of a waist truss for super high-rise buildings in the prior art I (Chinese Patent with application number 202121134531.1 and application date May 25, 2021) includes an upper frame beam on the upper floor, a lower frame beam on the lower floor, and a first frame column and a second frame column arranged on the outside of the structure. It includes truss straight web members and parallel frame beams. The truss straight web members are perpendicular to the lower frame beam. One end of the truss straight web member is fixedly connected to the lower frame beam, and the other end of the truss straight web member is fixedly connected to the upper frame beam. The parallel frame beams are perpendicular to the first frame column. One end of the parallel frame beam is fixedly connected to the lower frame beam, the middle end of the parallel frame beam is fixedly connected to the truss straight web member, and the other end of the parallel frame beam is fixedly connected to the upper frame beam.

[0004] Although the prior art can simplify the stress situation, during operation, the structure of the waist truss is composed of truss straight web members and parallel frame beams arranged only vertically or horizontally and frame beams and frame columns. Therefore, the overall design and installation have high precision requirements, making the overall construction process complex and time-consuming. When the overall structure is subjected to oblique stresses, the web members may bend, affecting the overall stability. Moreover, with horizontal and vertical settings, the overall connection is relatively fragile, affecting the safety of the overall structure. In view of the above problems, there is an urgent need to innovate on the basis of the original node structure of the waist truss and outrigger truss of super high-rise buildings. Therefore, we have proposed a node structure of a waist truss and an outrigger truss for super high-rise buildings that can well solve the above problems. Summary of the Invention

[0005] The object of the present invention is to provide a node structure for the waist truss and outrigger truss of a super high-rise building, so as to solve the problems raised in the above-mentioned background technology. The structure of the waist truss currently on the market that uses straight web members of the truss and parallel frame beams arranged only vertically or horizontally and frame beams and frame columns has relatively high precision requirements in the overall design and installation, making the overall construction process complex and time-consuming. When the overall structure is subjected to oblique stress, the web members may bend, thus affecting the overall stability. Moreover, with the horizontal and vertical settings, the overall connection is relatively fragile, affecting the safety of the overall structure.

[0006] To achieve the above object, the present invention provides the following technical solution: A node structure for the waist truss and outrigger truss of a super high-rise building, including a set of frame columns. A frame beam is arranged at the side end of the frame column. Threaded grooves are opened on the frame column, and the threaded grooves are adapted to fixing bolts. An elastic sheet is sleeved outside the fixing bolts. The fixing bolts penetrate through the frame beam and are connected inside the threaded grooves. A support sheet is arranged inside the frame beam. An inclined truss is welded to the frame beam through a welding sheet. The inclined trusses are arranged in a cross manner. The side end of the frame column is connected to an outrigger truss body through an inclined plate. The frame column is installed at the required position, thereby ensuring the accurate positioning of the building's vertical structure, providing a stable foundation for the subsequent construction and installation, reducing the problem of increased construction duration caused by inconvenient installation, and using the cooperation of the fixing bolts and the threaded grooves to install the frame beam on the frame column. Since an elastic sheet is installed outside the fixing bolts, the elastic sheet helps to balance and evenly transfer the load, effectively avoiding local stress concentration in the structure caused by uneven load distribution, enhancing the reliability of the beam-column joint. Moreover, the support sheet inside the frame beam greatly improves the overall support stability, enhancing the load-bearing capacity and anti-deformation ability of the horizontal structure. The overall structure is stable, reducing the problem of bending of the web members when subjected to oblique stress, and improving the overall stability. The side end of the frame column connects the outrigger truss body through an inclined plate, strengthening the connection between the horizontal structure and the oblique structure.

[0007] Preferably, a welding assembly is arranged on the inclined truss. The welding assembly includes a support member installed inside the inclined truss. A node plate is arranged on the support member. The node plate is welded inside a clamping groove and is welded to the side end of the frame column. The support member is placed inside the inclined truss, and the node plate is clamped into the clamping groove, and the overall connection is welded, improving the safety of the overall structure. The frame beam and the inclined truss are welded through a welding sheet, forming a rigid connection between the frame beam and the inclined truss, enhancing the spatial stability of the structure, being able to effectively transfer and distribute the horizontal and vertical loads between the frame beam and the inclined truss, improving the seismic and wind resistance capabilities of the entire structural system, and enhancing the spatial stress-bearing performance of the structure.

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

[0009] Preferably, a casting groove is formed at the side end of the support base, a first cavity is formed inside the support base, the first cavity is communicated with the casting groove, support steel bars are arranged inside the first cavity, and the support steel bars are arranged in a staggered manner. Pouring concrete into the first cavity through the casting groove at the side end of the support base facilitates the cooperation of the concrete and the support steel bars for stable support. The staggered support steel bars are convenient for stable support and enhance the bearing capacity of the support base.

[0010] Preferably, a second cavity is formed inside the frame column, and an inclined block is installed inside the second cavity. The inclined block arranged inside the second cavity of the frame column 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, which helps to reduce the phenomenon of local stress concentration and improve the stability of the overall structure.

[0011] Preferably, a first storage groove is formed inside the outrigger truss body, a limiting column penetrates through the first storage groove, and an eccentric wheel is sleeved outside the limiting column.

[0012] Preferably, an auxiliary assembly is provided inside the first storage groove. The auxiliary assembly includes a limiting block installed inside the first storage groove, and a moving rod penetrates through the limiting block. After the limiting column penetrates through the inclined plate and rotates inside the first storage groove, the eccentric wheel outside the limiting column rotates. 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 outside the moving rod facilitates the rebound during later disassembly, making the overall maintenance convenient.

[0013] Preferably, a first spring is sleeved outside the moving rod, and a first moving plate is arranged at one end of the moving rod. The first moving plate contacts the rotated eccentric wheel.

[0014] Preferably, a rotating plate is provided at the other end of the moving rod. The rotating plate is connected inside the second storage groove through a rotating seat. The second storage groove is opened inside the frame column. After the rotating plate rotates, it contacts the second moving plate. A screw rod is provided at the side end of the second moving plate. A second spring is sleeved outside the screw rod. The moving rod presses the rotating plate inside the second storage groove, causing the rotating plate to rotate inside the second storage groove through the rotating seat. The other end of the rotating plate moves the second moving plate, causing the screw rod at the side end of the second moving plate to pass through the through hole on the inclined plate. The second spring outside the screw rod facilitates the rebound during later disassembly, connects the screw rod and the nut, and connects the inclined plate with the frame column and the boom truss body. This not only ensures that the three can work together to jointly bear and transfer 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: For the joint structure of the waist truss and the boom truss of the super high-rise building, the support pieces inside the frame beam greatly improve the overall support stability, enhance the load-bearing capacity and anti-deformation ability of the horizontal structure. Using welding pieces to weld the frame beam and the inclined truss improves the spatial stress performance of the structure. The overall structure is stable, reducing the problem of the web member bending when subjected to oblique stress, and improving the overall stability. The specific content is as follows:

[0016] (1) The support pieces inside the frame beam greatly improve the overall support stability, enhance the load-bearing capacity and anti-deformation ability of the horizontal structure. Using welding pieces to weld the frame beam and the inclined truss improves the spatial stress performance of the structure, reducing the problem of the web member bending when subjected to oblique stress;

[0017] (2) The seismic isolation seat under the support seat can reduce the influence of seismic loads on the structure, ensure the node stability, effectively improve the safety of the building under seismic action, and the concrete and the support steel bars cooperate for stable support, enhancing the load-bearing capacity of the support seat;

[0018] (3) An inclined block is provided inside the second cavity of the frame column. The setting of 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 body, enhancing the stability of the overall structure;

[0019] (4) Pass the limit column of the auxiliary component through the inclined plate and rotate it inside the first storage groove, causing the eccentric wheel outside the limit column to rotate. After the eccentric wheel rotates, it contacts the first moving plate. The overall structure is simple, facilitating later maintenance, and reducing the problem of increased costs caused by complex structures;

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