Description

Technical Field

[0001] This invention relates to the field of structural engineering - seismic isolation technology, and in particular to a multifunctional integrated node and building that combines load-bearing, seismic isolation and vibration reduction. Background Technology

[0002] Bolted connections have gained widespread use due to their numerous significant advantages. Specifically, bolted connections eliminate the need for on-site welding; welding often requires protective measures, while bolted connections avoid this cumbersome step. Furthermore, the quality of bolted connections is relatively easy to control, allowing for efficient connection work during construction and significantly improving construction efficiency. They are also adaptable to connecting different materials, demonstrating strong versatility, and their seismic performance is excellent. However, bolted joints still have some drawbacks:

[0003] (1) Bolted connections have high requirements for installation. Generally, the bolt hole is 1-2mm larger than the bolt diameter, which puts high demands on the accuracy of processing and manufacturing as well as on-site installation. During processing and installation, special attention should be paid to the accuracy of dimensions, as even slight deviations may affect the quality and performance of the connection.

[0004] (2) The existing bolted joints mainly serve to bear loads, and their function is relatively simple. During an earthquake, these joints often serve as key points for force transmission and are easily damaged, which is very detrimental to the safety of the entire structure and may seriously affect the stability of the structure.

[0005] (3) For current energy dissipation devices, the conventional deployment locations are mainly concentrated at the bottom of columns, foundations and diagonal braces. Moreover, existing energy dissipation nodes have certain limitations. They can only dissipate energy in a single direction and cannot effectively control displacement, which to some extent limits their application effect under complex working conditions.

[0006] (4) The friction-type sliding connection currently used in diagonal bracing and beam-column joints has the disadvantage of only being able to dissipate energy in one direction. In addition, the stiffness of the sliding section is not adjustable, and only rigid body displacement is generated. This means that its energy dissipation capacity is not fully utilized, and it is also easy to cause sudden displacement of the structure during the use of the structure, which poses a potential threat to the safety and stability of the structure.

[0007] Taking the steel frame-reinforced concrete core tube structure, widely used in high-rise buildings, as an example, there is a significant difference in ductility between the concrete core tube and the steel frame. Specifically, the ductility coefficient of the concrete core tube is 3-4, while that of the steel frame is as high as 7-9. They work together through "deformation coordination," but when the concrete core tube reaches its ductility limit, the ductility performance of the steel frame is far from being fully realized. When using conventional joints, these joints can only bear the load but cannot dissipate energy or reduce vibration, thus failing to effectively protect the structure's safety in the event of disasters such as earthquakes.

[0008] In steel frame structures, there is a type of energy-dissipating beam-column joint that can slide; however, this joint also has the following drawbacks:

[0009] (1) This kind of sliding energy-consuming node can only achieve deformation in a single direction and cannot achieve multi-directional deformation. This makes it inadequate when dealing with complex force conditions and unable to adapt well to forces in different directions.

[0010] (2) According to the existing specifications, only one bolt can be arranged in a single slot, which seriously increases the processing difficulty; this requirement also makes the node need to be larger in size to meet the space requirements for bolt arrangement, making the construction more complicated.

[0011] (3) The node was designed with only its load-bearing and damping capacity in mind, but its potential seismic isolation capacity was not fully utilized and its function was not maximized. There is room for improvement.

[0012] (4) Similarly, the stiffness of this friction-type sliding connection cannot be adjusted in the sliding section, and only rigid body displacement is generated. Its energy dissipation capacity is not fully utilized, and during the use of the structure, it is easy to cause sudden displacement of the structure, which poses a hidden danger to the normal use and safety of the structure. Summary of the Invention

[0035] One or more of the first connecting devices are provided in each of the third elongated through holes.

[0036] Furthermore, friction plates are provided on the upper and lower flanges of the H-shaped steel beam and on the upper and lower end faces of the connecting cylinder, and a first clamping plate and a second clamping plate are provided on the outer side of the friction plates;

[0037] The friction plate is provided with two fourth elongated through holes parallel to the axial direction of the H-shaped steel beam, and the two fourth elongated through holes are respectively provided at the corresponding positions of the H-shaped steel beam and the connecting cylinder;

[0038] The first clamping plate is disposed at the corresponding position of the H-beam, and the second clamping plate is disposed at the corresponding position of the connecting cylinder;

[0039] The first clamping plate and the H-shaped steel beam are connected and clamp the friction plate by a fastening device, and the second clamping plate and the connecting cylinder are connected and clamp the friction plate by a fastening device, which passes through the fourth elongated through hole.

[0040] Furthermore, the first elongated through hole, the second elongated through hole, the third elongated through hole, and the fourth elongated through hole are all segmented slot holes;

[0050] On the other hand, this application also discloses a building that includes a multi-functional integrated node for load-bearing, damping, and seismic isolation.

[0051] By adopting the above technical solution, the present invention has the following beneficial effects:

[0052] (1) In the field of building structural design, the application of multi-functional integrated nodes for load bearing, vibration reduction, and seismic isolation is of great significance. When encountering relatively strong earthquakes such as moderate and major earthquakes, this multi-functional integrated node can play a unique role. It can effectively reduce the overall stiffness of the structure, making the structure's response under seismic loading more reasonable. By reducing the overall stiffness of the structure, the natural period of the structure can be increased. The increase in the natural period of the structure means that the vibration characteristics of the structure in an earthquake have changed, thereby reducing the input of seismic loading to the structure. In this way, the node can play the role of seismic isolation and friction energy dissipation, reducing the damage caused by earthquakes to the structure and ensuring the safety and stability of the building structure.

[0053] (2) The triaxial seismic isolation node is an advanced node designed based on the principles of sliding friction and kinematic synthesis. It resists seismic forces from any direction by utilizing the kinematic synthesis of orthogonal slots in high-strength bolts. During an earthquake, regardless of the origin of the seismic waves, this node, with its unique structure and working principle, can effectively cope with the seismic forces. In this way, the triaxial seismic isolation node achieves a multi-functional integration of load-bearing, seismic reduction, and seismic isolation. It possesses many significant advantages, such as a large load-bearing capacity, capable of withstanding large loads; high energy dissipation and seismic reduction efficiency, capable of quickly and effectively dissipating seismic energy; easy post-earthquake repair and replacement, rapidly restoring structural function; simple construction, facilitating design and construction; low cost, offering significant economic advantages; flexible use, allowing for rational application according to different engineering needs; and convenient installation, shortening the construction cycle.

[0054] (3) This node has strong design flexibility, one of its significant features being the decoupling of damping force and sliding displacement. This indicates that the damping force and sliding displacement can be adjusted and designed independently during the design process. By adjusting the slot size and bolt settings, arbitrary design of sliding displacement and damping force can be achieved to meet the specific requirements of different projects. At the same time, the node has a limiting function, which can prevent excessive displacement of the node under seismic loading and ensure the safety of the structure. During the node sliding process, its stiffness can be adjusted. Designers can reasonably design the stiffness of the node according to the actual engineering requirements. This can better achieve the goals of energy dissipation and periodic adjustment, optimize the performance of the structure under seismic loading, and improve the seismic resistance of the structure.

[0076] The present invention will be further explained below with reference to specific embodiments.

[0077] Example 1

[0078] This application discloses a multi-functional integrated node that combines load-bearing, vibration reduction, and seismic isolation. It is connected by high-strength bolts with multiple slots, which can control the magnitude of the transmitted load, dissipate seismic loads through sliding energy dissipation and concentrate the damage in the energy dissipation section, adjust the stiffness during the sliding process, and fully utilize the ductility of the connected structures in the ultimate state to achieve the purpose of performance synergy.

[0079] The principle is as follows: The node is set at the connection of the structure. By adjusting the multi-functional integrated node parameters of bearing-damping-isolation, the steel frame and the concrete core tube can achieve multi-stage collaborative work: (1) The node does not slip when subjected to minor earthquakes and wind loads. The deformation of the steel frame and the concrete core tube is coordinated to meet the requirements of no damage in minor earthquakes and comfort in wind vibration; (2) During moderate and major earthquakes, the steel frame and the concrete core tube will slip relative to each other through the multi-functional integrated node of bearing-damping-isolation, which will reduce the overall stiffness of the structure, increase the natural period of the structure, reduce the input of seismic action, and play the role of isolation and friction energy dissipation damping; (3) According to the design requirements, the stiffness during slip can be controlled, which can adjust the stiffness during the slip process so that the structure can better perform its own performance; (4) When the limit state is reached, the node parameters can be adjusted so that each component can reach its own inter-story drift angle limit at the same time, and the ductility performance can be fully utilized at the same time. The steel frame and the concrete core tube are upgraded from "deformation coordination" to "performance coordination".

[0080] like Figure 1-4 As shown, this embodiment provides a multi-functional integrated node for load-bearing, vibration reduction, and seismic isolation, including an H-shaped steel beam 1 and a vertical load-bearing structure 2;

[0081] One end of the H-shaped steel beam 1 is connected to the vertical load-bearing structure 2 through a three-way sliding joint;

[0082] The three-way sliding node includes an embedded part 3 and a connecting angle steel 4;

[0083] The embedded component 3 includes an integrated embedded plate 5 and a connecting cylinder 6;

[0084] The embedded plate 5 is embedded in the vertical load-bearing structure 2;

[0085] The connecting cylinder 6 extends out of the vertical load-bearing structure 2 and is connected to the connecting angle steel 4;

[0086] The connecting angle steel 4 is a T-shaped structure, including a first plate 7 and a second plate 8 that are vertically connected;

[0087] The first plate 7 is connected to the web of the H-beam 1;

[0088] The second plate 8 is connected to the connecting cylinder 6.

[0089] This embodiment achieves spatial freedom of adjustment between the H-beam 1 and the vertical load-bearing structure 2 through a three-way sliding joint, effectively adapting to deformation requirements in the vertical, lateral, and torsional directions, and improving the seismic performance of the structure. The coordinated design of the embedded part 3 and the connecting angle steel 4 not only ensures the stability of the joint connection but also allows for a certain degree of relative displacement, thereby achieving a synergistic effect of vibration reduction and isolation. The T-shaped structure of the connecting cylinder 6 and the connecting angle steel 4 is fixed with high-strength bolts, facilitating installation and disassembly, and is suitable for industrialized construction requirements. When subjected to cyclic loads or seismic action, this joint can significantly reduce stress concentration, improving the safety and durability of the overall structure. At the same time, this joint has good adjustability during manufacturing and installation, and the sliding gap and preload can be adjusted according to actual engineering needs to achieve an optimized match between stiffness and damping, further enhancing the structure's adaptability to multidimensional seismic motion. The double-plate design of the T-shaped connecting angle steel 4 effectively disperses the force transmission path, enhances the energy dissipation performance of the joint area, and avoids local stress concentration.

[0090] As a further embodiment of this embodiment, the connecting cylinder 6 is provided with a first elongated through hole 9 in a first direction;

[0091] The second plate 8 is provided with a second elongated through hole 10 in a second direction;

[0092] The first direction and the second direction are perpendicular to each other.

[0093] As a further embodiment of this embodiment, the first plate 7 is provided with a third elongated through hole 11 in a third direction;

[0094] The third direction is parallel to the axial direction of the H-beam 1;

[0095] The H-beam 1 is provided with a connection hole 12;

[0096] The connection hole 12 corresponds to the position of the third elongated through hole 11.

[0097] As a further embodiment of this embodiment, the first plate 7 and the web of the H-shaped steel beam 1 are connected by a first connecting device 13;

[0098] The second plate 8 and the connecting cylinder 6 are connected by the second connecting device 14.

[0099] As a further embodiment of this embodiment, both the first connecting device 13 and the second connecting device 14 are fasteners;

[0100] One or more of the first connecting devices 13 are provided in each of the third elongated through holes 11.

[0101] This application employs a friction-type connection to achieve a multi-functional integrated node that combines load-bearing, vibration reduction, and seismic isolation. Slots are created at key locations, and pre-tightened bolts are used. Utilizing interface slippage, the node remains stationary under normal loads but can slide and dissipate energy under severe earthquakes. Existing technologies typically place only one bolt within a single slot, increasing manufacturing difficulty and requiring larger nodes to accommodate the bolt placement, thus complicating construction. This embodiment, by placing multiple fasteners within a single elongated through-hole, effectively improves connection density and stress uniformity, reducing stress concentration in the node area. The collaborative work of multiple fasteners enhances the stability of the friction interface, improves stiffness retention under normal loads, and enables controlled slippage and efficient energy dissipation under seismic loading. This design reduces dependence on component dimensions, facilitating smaller node volumes, improving space utilization efficiency, and simplifying the installation process to meet the demands of rapid industrial construction.

[0102] The initial preload and bolt specifications should be selected according to the specifications, ranging from 125kN to 355kN and from M20 to M30, respectively. Based on the inventor's previous experiments on friction-type connections with high-strength bolts, using parameters such as M30 slots, a preload of 350kN, and sandblasting of the friction surface can result in a full hysteresis curve at the slotted slip joint (e.g., ...). Figure 11 and 12 (As shown in the figure). However, as the number of slip cycles increases, the bearing capacity of the node continuously decreases. This is because the bolt preload decreases with the increase of hysteresis cycles, resulting in a decrease in frictional resistance. Nevertheless, the hysteresis curves of the specimens under each load level are full, close to rectangular, and have a large ultimate displacement.

[0103] Preferably, this embodiment can adopt different friction surface arrangements according to the building height and seismic fortification intensity, including sandblasting of the contact surface, spraying of coatings, setting of brass gaskets, polytetrafluoroethylene gaskets, etc. For the structure, based on this node, rapid installation can be achieved (the slot layout allows the total error of installation + manufacturing to be expanded to more than 8mm). For the structural system, this node has good energy dissipation capacity and can play the role of seismic isolation and friction energy dissipation damping in the structure under moderate and major earthquakes, realizing the performance synergy of intra-story seismic isolation, core tube and steel frame.

[0104] As a further embodiment of this invention, the first connecting device 13 is a fastener;

[0105] The second connecting device 14 is a prestressed structure;

[0106] One end of the second connecting device 14 is anchored to the embedded plate 5, and the other end passes through the first elongated through hole 9 and the second elongated through hole 10 and is anchored to the end of the second plate 8 away from the embedded part 3.

[0107] In a preferred embodiment of this invention, the prestressed structure is a prestressed steel bar or an SMA wire.

[0108] In this embodiment, the prestressed steel bars or SMA wires can generate a self-resetting effect during the stress process, causing the node to return to its initial position after an earthquake or strong wind, effectively reducing residual deformation. SMA wires also possess excellent energy dissipation capacity and superelastic properties, further enhancing the node's adaptive performance. By adjusting the prestressing force, the prestressed structure can achieve precise control over the node stiffness and reset capability, meeting the seismic requirements under different seismic intensities. This design, while ensuring connection strength, also considers multiple functions such as slippage, energy dissipation, and reset, making it suitable for buildings and important infrastructure projects in high-intensity seismic zones. By setting mutually perpendicular elongated through-holes, controllable slippage of the node in two orthogonal directions is allowed, effectively releasing additional stress under seismic action. The elongated through-hole in the third direction is aligned with the axis of the H-beam 1, further ensuring longitudinal deformation coordination. The prestressed structure provides restoring force during vibration, preventing node instability after slippage. During installation, the entire node's stress performance can be optimized on-site by adjusting the prestressing force of the fasteners and the tension of the prestressing tendons, improving construction adaptability and quality control. Through the synergistic effect of the above structures, the nodes exhibit excellent energy dissipation stability and reset capability under multi-directional seismic input, which can also significantly reduce post-earthquake repair costs.

[0109] As a further embodiment of this embodiment, friction plates 15 are provided on the upper and lower flanges of the H-shaped steel beam 1 and the upper and lower end faces of the connecting cylinder 6, and a first clamping plate 16 and a second clamping plate 17 are provided on the outer side of the friction plates 15.

[0110] The friction plate 15 is provided with two fourth elongated through holes parallel to the axial direction of the H-shaped steel beam 1. The two fourth elongated through holes are respectively located at the corresponding positions of the H-shaped steel beam 1 and the connecting cylinder 6.

[0111] The first clamping plate 16 is disposed at the corresponding position of the H-beam 1, and the second clamping plate 17 is disposed at the corresponding position of the connecting cylinder 6;

[0112] The first clamping plate 16 and the H-shaped steel beam 1 are connected and clamp the friction plate 15 by a fastening device. The second clamping plate 17 and the connecting cylinder 6 are connected and clamp the friction plate 15 by a fastening device, which passes through the fourth elongated through hole.

[0113] In this embodiment, a friction plate 15 with elongated through holes and a clamping structure are installed between the H-shaped steel beam 1 and the connecting cylinder 6 to achieve multi-directional sliding and frictional energy dissipation of the node under seismic loading. A stable friction interface is formed between the friction plate 15 and the clamping plate under the action of preload. Under the action of seismic cyclic load, frictional damping is generated through sliding, which effectively dissipates seismic energy and avoids plastic damage to the components.

[0114] It should be noted that the technical solution of this embodiment can be used independently, that is, both ends of the H-shaped steel beam 1 and the vertical load-bearing structure 2 are connected through the three-way sliding node disclosed in this embodiment, or it can be combined with the technical solution of embodiment 3 as described in embodiment 3.

[0115] By adopting the above technical solution, the present invention has the following beneficial effects:

[0116] (1) By adjusting the node parameters, the steel frame and the concrete core tube can work together in multiple stages. The deformation is coordinated under small earthquakes and wind loads, which meets the requirements of no damage under small earthquakes and comfort under wind vibration. Relative slip occurs under moderate and large earthquakes, which reduces the overall stiffness, increases the natural period, and reduces the input of seismic action, thus playing the role of seismic isolation and friction energy dissipation. The stiffness can be adjusted during slip, so that the structure can better perform its own performance. In the ultimate state, each component reaches the inter-story drift angle limit at the same time, and the ductility performance is exerted at the same time, realizing the improvement from "deformation coordination" to "performance coordination".

[0117] (2) The three-way sliding joint enables spatial degree of freedom adjustment between the H-beam and the vertical load-bearing structure, effectively adapting to the deformation requirements in the vertical, horizontal and torsional directions, and improving the seismic performance of the structure. The embedded parts and connecting angle steel work together to ensure stable connection and allow relative displacement, and work together to achieve the functions of vibration reduction and seismic isolation.

[0118] (3) The connecting cylinder and the connecting angle steel T-shaped structure are fixed with high-strength bolts, which facilitates installation and disassembly and is suitable for industrialized construction. The manufacturing and installation are highly adjustable, and the sliding gap and preload can be adjusted according to the engineering requirements to optimize the matching stiffness and damping and improve the structure's adaptability to multidimensional ground motion.

[0119] (4) The T-shaped connecting angle steel double plate design disperses the force transmission path, enhances the energy dissipation performance of the node area, and avoids local stress concentration. When subjected to periodic loads or seismic action, it can significantly reduce stress concentration and improve the overall structural safety and durability.

[0120] (5) Friction-type connection is adopted, with slots and pre-tightened bolts at key locations to achieve no movement under normal loads and energy dissipation through slippage during major earthquakes. Different friction surfaces are arranged according to the building height and seismic fortification intensity, which has good energy dissipation capacity, can be installed quickly, and achieves synergistic performance of intra-story seismic isolation, core tube and steel frame.

[0121] (6) Prestressed steel bars or SMA wires generate a self-resetting effect, reducing residual deformation after earthquakes or strong winds. SMA wires also have excellent energy dissipation and superelasticity properties, improving the adaptive performance of nodes. Prestressed structures can precisely control node stiffness and reset capability to meet the seismic requirements of different seismic intensities.

[0122] (7) Set mutually perpendicular long strip through holes to allow the nodes to slide controllably in two orthogonal directions and release the additional stress of the earthquake; the third-direction long strip through holes ensure the longitudinal deformation coordination capability; the prestressed structure provides the restoring force to avoid the node from becoming unstable after sliding.

[0123] (8) A friction plate with long through holes and a clamping structure are installed between the H-shaped steel beam and the connecting cylinder to achieve multi-directional sliding and friction energy dissipation. The friction interface is stable under the action of preload, and friction damping is generated through sliding under seismic reciprocating load, which effectively dissipates seismic energy and avoids plastic damage to the components.

[0124] Example 2

[0125] like Figure 5-7 As shown, this embodiment is a further improvement on the basis of embodiment 1, specifically, the first elongated through hole 9, the second elongated through hole 10, the third elongated through hole 11 and the fourth elongated through hole are all segmented slot holes 18;

[0126] The first connecting device 13, the second connecting device 14, and the fastening device are all fastening bolts 19;

[0127] The segmented slot 18 is divided into multiple segments of different widths, which are used to control the displacement of the fastening bolt 19 at different stages.

[0128] As a further embodiment of this embodiment, a hard sheet 20 is provided in the area of ​​the outer periphery of the middle part of the fastening bolt 19 located within the segmented slot 18;

[0129] The segmented slot 18 includes a wide section 21, a middle section 22 and a narrow section 23, wherein the width of the wide section 21 is greater than the outer diameter of the rigid sheet 20.

[0130] The width of the middle section 22 is greater than the outer diameter of the thread of the fastening bolt 19, but smaller than the outer diameter of the rigid plate 20.

[0131] The width of the narrow section 23 is less than the outer diameter of the thread of the fastening bolt 19.

[0132] In this embodiment, when the fastening bolt 19 is inserted into the segmented slot 18, the rigid plate 20 can move freely within the wide section 21, enabling free adjustment during the installation stage and flexible adjustment under natural disasters such as minor earthquakes. When the node is subjected to a moderate earthquake, the rigid plate 20 moves into the middle section 22 with the fastening bolt 19, and is constrained by the side wall of the middle section 22, increasing the friction interface pressure and thus improving the sliding bearing capacity, achieving a self-enhancing stiffness of the friction energy dissipation mechanism. When the earthquake further intensifies, the rigid plate 20 is obstructed and damaged and falls off when it is about to enter the narrow section 23. The fastening bolt 19 continues to slide into the narrow section 23 and forms a mechanical limit. Since the diameter of the fastening bolt 19 is smaller than the width of the narrow section 23, the bolt shank makes rigid contact with the side wall of the narrow section 23, forming a plastic hinge mechanism, achieving a secondary enhancement of the structural bearing capacity. Through the synergistic effect of the segmented slot 18 and the fastening bolt 19 with the rigid plate 20, the node achieves a multi-stage seismic resistance mechanism transformation from elastic sliding and friction energy dissipation to plastic deformation. This design not only enhances the structure's adaptability to different earthquake magnitudes but also effectively controls damage concentration, ensuring overall stability and recoverability. The interrelationships between components guarantee a balance between ease of installation and long-term durability, significantly improving the safety redundancy of connection nodes and post-earthquake repair efficiency.

[0133] Specifically, the width of the wide section 21 is 1-2 mm wider than the diameter of the hard plate 20, and the width of the narrow section 23 is 1-3 mm narrower than the diameter of the fastening bolt 19.

[0134] It should be noted that in this embodiment, each elongated through hole can be a segmented slot hole 18, or only some of them can be segmented slot holes 18 while the rest are ordinary slot holes. Similarly, the first connecting device 13, the second connecting device 14 and the fastening device can all be fastening bolts 19, or only some of them can be fastening bolts 19. This application does not make any further limitations here.

[0135] As a further embodiment of this embodiment, a return spring 44 is provided at both ends of the segmented slot 18;

[0136] One end of the return spring 44 abuts against the end of the segmented slot 18, and the other end abuts against the hard sheet 20.

[0137] As a further embodiment of this embodiment, the segmented slot 18 is filled with a rubber layer 24 and a resin layer 25.

[0138] The rubber layer 24 is filled in the wide section 21, and the resin layer 25 is filled in the middle section 22 and the narrow section 23.

[0139] In this embodiment, the use of a return spring 44 or a rubber layer 24 and resin layer 25 structure effectively enhances the self-resetting capability and damping performance of the node. After an earthquake, the return spring 44 pushes the rigid plate 20 back to the initial position of the wide section 21, achieving partial automatic restoration of the connection state. The rubber layer 24 provides elastic buffering in the wide section 21, reducing the transmission of high-frequency vibrations, while the resin layer 25 enhances the interface density in the middle section 22 and narrow section 23, preventing impurities from entering and maintaining a stable coefficient of friction. The multiple structures synergistically optimize the mechanical response and durability of the node under multiple load levels, further ensuring long-term service performance. The pre-compression design of the return spring 44 ensures that it engages in operation under slight vibrations, effectively suppressing node loosening. The interface between the rubber layer 24 and the resin layer 25 is chemically anchored, significantly improving durability and environmental adaptability.

[0140] like Figure 13-14 As shown, in this embodiment, the rubber layer 24 and resin layer 25 are filled into the segmented slot 18 by setting an injection port 45 and an observation port 46 on the plate. The injection port 45 is located at the bottom and the observation port 46 is located at the top. After injection from the injection port 45 at the bottom, the injection is stopped and the medium is allowed to solidify when the injected medium reaches the observation port 46.

[0141] Specifically, the injection port 45 is located at a position on the lower plate that is not blocked by the fastening bolt 19, or the injection port 45 is located at a position on the lower plate that is blocked by the fastening bolt 19, and an extension groove 47 is formed at the fastening bolt 19 corresponding to the injection port 45, so that the injection medium is injected from the extension groove 47 to the injection port 45.

[0142] By adopting the above technical solution, the present invention has the following beneficial effects:

[0143] (1) Through the synergistic effect of segmented slots and fastening bolts with rigid plates, the node achieves a multi-stage seismic resistance mechanism transformation from elastic slip and frictional energy dissipation to plastic deformation. During the installation stage, the rigid plates move freely in the wide section, facilitating installation and adjustment, and allowing for flexible adjustment even during minor earthquakes. During moderate earthquakes, the rigid plates are constrained in the middle section, increasing the pressure at the friction interface, enhancing the slip bearing capacity, and achieving self-enhancing stiffness. During strong earthquakes, the rigid plates are damaged and fall off, and the fastening bolts slip to the narrow section, forming a mechanical limiting and plastic hinge mechanism, which further enhances the structural bearing capacity. This improves the structure's adaptability under different earthquake levels, effectively controls damage concentration, and ensures overall stability and recoverability.

[0144] (2) The components fit together well, and the wide-section design allows the rigid plate to move freely during installation, ensuring ease of installation. At the same time, this design takes into account long-term durability, significantly enhances the safety redundancy of the connection nodes, reduces safety hazards caused by installation problems or long-term use, and extends the service life of the nodes.

[0145] (3) The multi-stage seismic resistance mechanism and reasonable design enable the nodes to maintain a good state after the earthquake, reduce the possibility of large-scale damage, reduce the difficulty and workload of post-earthquake repair, improve the efficiency of post-earthquake repair, and can quickly restore the normal use function of the structure, reducing the impact of earthquake on production and life.

[0146] (4) The reset spring 44 or the structure of filling rubber layer and resin layer effectively improves the self-reset capability and damping performance of the node. After the earthquake, the reset spring 44 pushes the rigid plate back to the initial position of the wide section, realizing the automatic restoration of the connection state; the rubber layer provides elastic buffer in the wide section to reduce the transmission of high frequency vibration; the resin layer enhances the interface density in the middle and narrow sections to prevent impurities from entering and maintain the stability of the friction coefficient.

[0147] (5) The multi-structure synergistic optimization of the node’s mechanical response and durability under multi-level loads. The preload design of the reset spring 44 ensures that it can work under slight vibration, effectively suppressing node loosening; the interface between the rubber layer and the resin layer is chemically anchored, which significantly improves durability and environmental adaptability, ensuring the long-term service performance of the node in complex environments.

[0148] (6) Each long through hole can be partially or entirely segmented slot holes, and the first connecting device, the second connecting device and the fastening device can also be partially or entirely fastening bolts. This flexible design can be adjusted according to actual engineering needs to meet the usage requirements of different structures and different working conditions, thereby improving the versatility and applicability of the technical solution.

[0149] (7) When filling the segmented slots with rubber and resin layers, the bottom injection port and the top observation port are reasonably set on the plate. The injection is carried out from the bottom. When the medium reaches the observation port, the injection is stopped and solidified. The operation is simple and can ensure the filling effect, so that the rubber and resin layers are accurately filled to the corresponding positions and give full play to their performance.

[0150] Example 3

[0151] like Figure 8-10 As shown, this embodiment provides a multi-functional integrated node for load bearing, vibration reduction, and seismic isolation, which also includes a high-strength load bearing connection node;

[0152] One end of the H-shaped steel beam 1 is connected to the vertical load-bearing structure 2 through a three-way sliding node, and the other end is connected to the vertical load-bearing structure 2 through a high-strength load-bearing connection node;

[0153] The connection nodes at the ends of two adjacent H-beams 1 are arranged in opposite ways. Specifically, the left end of one H-beam 1 is connected to the vertical load-bearing structure 2 via a three-way sliding node, and the right end is connected to the vertical load-bearing structure 2 via a high-strength load-bearing connection node. Similarly, the right end of an adjacent H-beam 1 is connected to the vertical load-bearing structure 2 via a three-way sliding node, and the left end is connected to the vertical load-bearing structure 2 via a high-strength load-bearing connection node. This alternating arrangement of redundant constraints and elastic release channels effectively enhances the seismic ductility and energy dissipation capacity of the frame system. With this arrangement, when the structure encounters an earthquake, the high-strength load-bearing connection nodes effectively transfer vertical loads and provide stiffness support, while the three-way sliding nodes allow controllable horizontal displacement between beams and columns, releasing seismic stress and preventing brittle failure.

[0154] This embodiment provides a high-strength load-bearing connection node, including a vertical load-bearing structure 2, an H-shaped steel beam 1, an inner connection component 27, an outer connection component 35, and a driving component 39. The side wall of the vertical load-bearing structure 2 has a connecting through hole 26 through which the inner connection component 27 can pass. The outer connection component 35 is fixedly installed on the side wall of the H-shaped steel beam 1. One end of the driving component 39 is connected to the outer connection component 35, and the other end is connected to the inner connection component 27. When the inner connection component 27 enters the interior of the vertical load-bearing structure 2 through the connecting through hole 26, the driving component 39 drives the inner connection component 27 to move inside the vertical load-bearing structure 2, so that the inner connection component 27 acts on the inner wall of the vertical load-bearing structure 2.

[0155] The specific operating procedure for connecting the H-beam 1 to the side wall of the vertical load-bearing structure 2 is as follows: First, the inner connecting component 27 can be slowly inserted into the interior of the vertical load-bearing structure 2 through the connecting through hole 26. This process requires ensuring that the inner connecting component 27 can pass smoothly through the connecting through hole 26, and care must be taken to avoid collisions or interference with other structures inside the vertical load-bearing structure 2 during insertion. Next, the H-beam 1 is placed on the outer side of the vertical load-bearing structure 2, and the end of the H-beam 1 must be precisely in close contact with the outer wall of the vertical load-bearing structure 2. This contact process requires ensuring a tight fit between the two to ensure the stability of the subsequent connection. Subsequently, the outer connecting component 35 is securely fixed to the side wall of the H-beam 1. When installing the outer connecting component 35, appropriate tools and methods should be used to ensure its secure installation and avoid loosening. Then, the driving component 39 is used to move the inner connecting component 27 inside the vertical load-bearing structure 2. The drive assembly 39 must operate smoothly and accurately, enabling the inner connecting assembly 27 to move within the vertical load-bearing structure 2 according to a predetermined trajectory and method, ultimately acting on the inner wall of the vertical load-bearing structure 2. At this time, the inner connecting assembly 27 provides effective support for the H-beam 1 from within the vertical load-bearing structure 2. This internal support enhances the stability of the connection between the H-beam 1 and the vertical load-bearing structure 2. Simultaneously, the outer connecting assembly 35 provides support for the H-beam 1 from outside the vertical load-bearing structure 2. These two support methods work together to successfully complete the connection between the H-beam 1 and the vertical load-bearing structure 2. By adopting this connection method, the connection area between the H-beam 1 and the vertical load-bearing structure 2 can be significantly increased. The increased connection area means a tighter and stronger connection, thus effectively improving the connection strength between the H-beam 1 and the vertical load-bearing structure 2. Improving the connection strength is crucial for the stability of the entire structure, and can greatly enhance the stability of the H-beam 1, enabling it to work more reliably when subjected to various external forces.

[0156] As a further embodiment of this invention, the external connecting component 35 includes a U-shaped plate 36 and a bolt and nut assembly 38. Two sets of U-shaped plates 36 are provided, each set embedded on opposite sides of the H-beam 1. The bolt and nut assembly 38 connects the H-beam 1 and the two sets of U-shaped plates 36 into a single unit. Specifically, bolt holes are provided on the web of the H-beam 1 and on the plates of the two sets of U-shaped plates 36, allowing bolts from the bolt and nut assembly 38 to pass through. After the two sets of U-shaped plates 36 are embedded on opposite sides of the H-beam 1, the bolt holes on the two sets of U-shaped plates 36 are aligned with the bolt holes on the web of the H-beam 1. Then, the bolts included in the bolt and nut assembly 38 are passed through the aligned bolt holes, and then the nuts included in the bolt and nut assembly 38 are used for locking, thereby connecting the two sets of U-shaped plates 36 and the H-beam 1 into a single unit.

[0157] As a further embodiment of this example, a plurality of ribs 37 are fixedly provided on the inner side of both sets of U-shaped plates 36.

[0158] The ribs 37 provide support for the U-shaped plate 36, thereby enhancing the rigidity of the U-shaped plate 36 and improving the external connection effect of the H-shaped steel beam 1.

[0159] As a further embodiment of this example, the drive assembly 39 includes a support tube 40 and a rotating shaft 42. The support tube 40 extends laterally through several ribs 37 and is fixedly connected to the ribs 37. A groove 41 is formed on the side wall of the support tube 40 along its length. One end of the rotating shaft 42 extends to the outside of the support tube 40, and the other end extends to the inside of the support tube 40 and is rotatably engaged with the support tube 40. Two sets of external threads 43 are formed on the shaft of the rotating shaft 42 located inside the support tube 40. The two sets of external threads 43 rotate in opposite directions. The inner connection assembly 27 includes an outer ring block 28, an inner support rod 30, an elastic element 32, an inner ring block 33, and a connecting rod 34. The outer ring block 28 and the inner ring block 33 are each provided with two... Two sets of outer ring blocks 28 are sleeved on the outside of the support tube 40, and two sets of inner ring blocks 33 are encircled inside the support tube 40. Two sets of inner ring blocks 33 are sleeved on the outside of the rotating shaft 42 and threadedly engaged with two sets of external threads 43. A connecting rod 34 is fixedly provided on the outer wall of each set of inner ring blocks 33. The end of the connecting rod 34 away from the corresponding inner ring block 33 extends from the sliding groove 41 to the outside of the support tube 40 and is fixedly connected to the outer ring block 28. Several inner support rods 30 are rotatably provided on the edges of the two sets of outer ring blocks 28 that are away from each other. Each set of inner support rods 30 is connected to the corresponding outer ring block 28 through an elastic element 32, which provides elastic tension to the inner support rods 30.

[0160] After securing the two sets of U-shaped plates 36 to opposite sides of the H-beam 1 using bolt and nut assemblies 38, on-site workers carefully hoisted the H-beam 1 to one side of the vertical load-bearing structure 2 using specialized hoisting machinery. Subsequently, the workers operated the hoisting machinery to slowly move the H-beam 1 closer to the side wall of the vertical load-bearing structure 2. During this process, the ribs 37 simultaneously propelled the support pipes 40 towards the side wall of the vertical load-bearing structure 2. When the H-beam 1 and support pipes 40 reached the appropriate position, workers could manually press down on several inner struts 30 on the two sets of outer ring blocks 28, applying pressure to keep the inner struts 30 horizontal.

[0161] When one end of the support tube 40 smoothly extends into the interior of the vertical load-bearing structure 2 through the connecting through hole 26, the two sets of outer ring blocks 28 and several inner support rods 30 will follow the support tube 40 into the interior space of the vertical load-bearing structure 2. After the several inner support rods 30 are fully inside the vertical load-bearing structure 2, several elastic elements 32 will generate tension, pulling the several inner support rods 30. Under the action of the tension of the elastic elements 32, the several inner support rods 30 will rotate to a vertical state. Subsequently, as the workers continue to operate the hoisting machinery to bring the H-beam 1 closer to the vertical load-bearing structure 2, after the end of the H-beam 1 contacts the outer wall of the vertical load-bearing structure 2, the workers begin to rotate the shaft 42. When the shaft 42 rotates, the two sets of external threads 43 respectively engage with the threads of the two sets of inner ring blocks 33. This engagement is like a precise gear transmission, thereby driving the two sets of inner ring blocks 33 to move away from each other along the interior of the support tube 40.

[0162] As the two sets of inner ring blocks 33 move away from each other, the two sets of outer ring blocks 28 are driven away from each other via connecting rods 34. Simultaneously, connecting rods 34 slide adaptively along the interior of the slide groove 41. The two sets of outer ring blocks 28 drive their respective inner support rods 30 away from each other. When the two sets of outer ring blocks 28 act on two opposite side walls inside the vertical load-bearing structure 2, they generate sufficient pressure to press the vertically positioned inner support rods 30 against the opposite side walls inside the vertical load-bearing structure 2. At this time, the inner support rods 30 can provide stable support for the support tube 40 from inside the vertical load-bearing structure 2. This support effect is transmitted to the H-beam 1 via ribs 37, thus cleverly distributing the force applied by the H-beam 1 to the two side walls of the vertical load-bearing structure 2. In this way, the connection area between the H-beam 1 and the vertical load-bearing structure 2 can be increased, effectively improving the overturning resistance of the H-beam 1, and thus significantly improving the connection strength of the H-beam 1.

[0163] As a further embodiment of this example, each of the two sets of outer ring blocks 28 has a plurality of second slots 31 at one of their mutually distant edges. One end of each of the plurality of inner support rods 30 extends into the interior of the plurality of second slots 31 and is rotatably connected to the inner wall of the second slot 31 by a pin (not shown in the figure). Each of the two sets of outer ring blocks 28 has a plurality of first slots 29 on its circumferential sidewalls. The plurality of first slots 29 are connected to the plurality of second slots 31. A vertical stepped surface (not shown in the figure) is formed between the first slot 29 and the corresponding second slot 31. One end of the elastic member 32 is connected to the inner wall of the first slot 29, and the other end is connected to the inner support rod 30.

[0164] On-site staff manually press several inner support rods 30 to keep them horizontal. When pressing, the elastic element 32 is subjected to tensile force, causing it to elongate. After the inner support rods 30, along with the inner ring block 28 and support tube 40, smoothly enter the vertical load-bearing structure 2 through the connecting hole 26, the elastic element 32, no longer under external pressure, can perform its elastic recovery function, pulling the inner support rods 30 and allowing them to rotate relative to the pin. When the inner support rods 30 reach a vertical position after rotation, one side of each rod acts on the vertical stepped surface, thus stably maintaining their vertical position.

[0165] In subsequent operations, the operator rotates the shaft 42, which in turn moves the two sets of outer ring blocks 28 in a direction away from each other. When the two sets of outer ring blocks 28 move away from each other, several inner support rods 30 located at the opposite ends of the two sets of outer ring blocks 28 are in a vertical state, and they act synchronously on the two opposite side walls inside the vertical load-bearing structure 2. These inner support rods 30 provide support to the support tube 40 from inside the vertical load-bearing structure 2 in this way. This support effect is transmitted to the rib plate 37 via the support tube 40, and then to the H-beam 1 via the U-shaped plate 36. Through this transmission process, the connection force applied by the H-beam 1 to one side wall of the vertical load-bearing structure 2 can be distributed to both side walls of the vertical load-bearing structure 2. This method of distributing the connection force can effectively improve the overturning resistance of the H-beam 1, thereby enhancing the connection strength between the H-beam 1 and the vertical load-bearing structure 2.

[0166] In the above operation, the arrangement of the elastic element 32 inside the first slot 29 is of great significance. It avoids the elastic element 32 protruding outwards, because if the elastic element 32 protrudes outwards, it may affect the smooth passage of the middle ring block 28 through the connecting through hole 26. Arranging it inside the first slot 29 ensures the smooth operation of the entire structure.

[0167] As a further embodiment of this example, the elastic element 32 can be a spring or a metal sheet, and there is no limitation here.

[0168] As a further embodiment of this invention, a sealing block (not shown in the figure) adapted to the connecting through hole 26 is also fixedly provided on the outer wall of the support tube 40.

[0169] After the two sets of outer ring blocks 28 are brought into the vertical load-bearing structure 2 through the connecting through hole 26 at one end of the support tube 40, the sealing block can then be embedded into the connecting through hole 26 to seal the connecting through hole 26, so as to prevent external dust and rainwater from entering the vertical load-bearing structure 2 through the gap between the connecting through hole 26 and the support tube 40, and prevent corrosion damage to the various structures of the inner connecting component 27.

[0170] As a further embodiment of this invention, when it is necessary to connect the H-beam 1 to the side wall of the vertical load-bearing structure 2, the inner connecting component 27 can first be inserted into the interior of the vertical load-bearing structure 2 through the connecting through hole 26. After completing this step, the H-beam 1 is then placed on the outside of the vertical load-bearing structure 2, and special attention should be paid to ensuring that the end of the H-beam 1 is in close contact with the outer wall of the vertical load-bearing structure 2. Subsequently, the outer connecting component 35 is fixedly installed on the side wall of the H-beam 1. Then, the driving component 39 is used to move the inner connecting component 27 inside the vertical load-bearing structure 2, allowing the inner connecting component 27 to act on the inner wall of the vertical load-bearing structure 2. At this time, the inner connecting component 27 provides corresponding support for the H-beam 1 from inside the vertical load-bearing structure 2, while the outer connecting component 35 provides support for the H-beam 1 from outside the vertical load-bearing structure 2. In this way, the connection between the H-beam 1 and the vertical load-bearing structure 2 can be successfully completed. Compared with existing technologies, the cooperation between the inner connecting component 27 and the outer connecting component 35 eliminates the need for numerous bolt holes on the side wall of the vertical load-bearing structure 2. This increases the connection area between the H-beam 1 and the vertical load-bearing structure 2, thereby improving the connection strength. Increased connection strength further enhances the stability of the H-beam 1 and strengthens the safety of the vertical load-bearing structure 2, ensuring greater reliability and stability of the entire structure during use.

[0171] It should be noted that the technical solution of this embodiment can be used independently, that is, both ends of the H-shaped steel beam 1 are connected to the vertical load-bearing structure 2 through the high-strength load-bearing connection node disclosed in this embodiment, or it can be combined with the technical solution of embodiment 1 as described in embodiment 1.

[0172] By adopting the above technical solution, the present invention has the following beneficial effects:

[0173] (1) By setting the connection nodes at the ends of adjacent H-shaped steel beams in opposite ways, redundant constraints and elastic release channels are alternately formed in the overall structure, which effectively improves the seismic ductility and energy dissipation capacity of the frame system. When an earthquake occurs, the high-strength load-bearing connection nodes effectively transfer vertical loads and provide stiffness support, while the three-way sliding nodes allow controllable horizontal displacement between beams and columns, releasing seismic stress, avoiding brittle failure, and enhancing the adaptability of the structure under different seismic conditions.

[0174] (2) A unique connection method is adopted, in which the inner connecting component provides support for the H-beam from inside the vertical load-bearing structure, and the outer connecting component provides support from the outside, with the inner and outer components working together to complete the connection. This connection method increases the connection area between the H-beam and the vertical load-bearing structure, making the connection tighter and stronger, significantly improving the connection strength, thereby enhancing the stability of the H-beam, ensuring its reliable operation under various external forces, and improving the safety of the vertical load-bearing structure, ensuring the stability and reliability of the entire structure.

[0175] (3) During the connection process, after the inner strut enters the interior of the vertical load-bearing structure, it rotates to a vertical state under the action of the elastic element and is pressed against the opposite side wall inside the vertical load-bearing structure, providing stable support for the support tube from the inside. The support effect is transmitted to the H-beam through the rib plate, dispersing the connection force applied by the H-beam to one side wall of the vertical load-bearing structure to the two side walls, effectively improving the overturning resistance of the H-beam.

[0176] (4) The U-shaped plates of the external connecting components are embedded on opposite sides of the H-beam and connected as a whole by bolt and nut assemblies. Ribs are set on the inner side of the U-shaped plates to strengthen the rigidity of the U-shaped plates and improve the external connection effect of the H-beam, providing a reliable foundation for the overall connection. The rotating shaft of the drive component drives the inner ring blocks to move away from each other along the inside of the support tube, and then drives the outer ring blocks and inner support rods to move away from each other through the connecting rod, so that the inner support rods press against the side wall of the vertical load-bearing structure to achieve internal support. The operation process is coordinated and efficient, ensuring a stable connection. The elastic element is arranged inside the first slot to avoid protrusion affecting the outer ring blocks from passing through the connecting through hole, ensuring the smooth operation of the structure, and at the same time playing an elastic recovery role, so that the inner support rods are stably maintained in a vertical state. The outer wall of the support tube is provided with a sealing block that matches the connecting through hole. After the support tube brings the outer ring blocks into the interior of the vertical load-bearing structure, the sealing block is embedded in the connecting through hole to seal, preventing external dust and rainwater from entering the interior of the vertical load-bearing structure, avoiding corrosion and damage to the internal connecting component structure, and extending the service life of the structure.

[0177] (5) Compared with the existing technology, this solution uses internal and external connecting components to cooperate, which eliminates the need to open too many bolt holes on the side wall of the vertical load-bearing structure, simplifies the construction process, reduces the construction difficulty, improves the construction efficiency, and can adapt to different engineering needs and site conditions, thus having a wider range of applicability.

[0178] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
