[0030] like Figure 1As shown, the seismic connection structure of this application includes several key components to ensure the stability and safety of the building structure under dynamic loads. Specifically, the connection structure mainly consists of a shear plate 1, anchor bolts 2, a rubber pad 3, and a reinforcing steel sleeve 4. The shear plate 1 is the core component of the connection structure, and its function is to effectively transfer and distribute the shear force of the building structure. The anchor bolts 2 fix the shear plate 1 in a predetermined position through connection with the wall embedded parts. The rubber pad 3 is located between the shear plate 1 and the anchor bolts 2, and is used to absorb the vibration energy generated by dynamic loads, thereby reducing the impact of vibration on the building structure. The reinforcing steel sleeve 4 is sleeved on the outside of the anchor bolts 2, which not only improves the shear strength of the connection part, but also reduces the possibility of frictional slippage.

[0031] Shear plate 1 is a key load-bearing component of this connection structure, and its installation position must correspond to the critical stress points of the building structure. Shear plate 1 is typically made of high-strength steel, possessing good ductility and corrosion resistance to ensure stable performance under high load conditions. To increase its load-bearing capacity, the surface of shear plate 1 may be hardened or a special welding process may be used. Anchor bolts 2 are the main components connecting shear plate 1 to the wall, and their threaded design ensures reliable fixing. Anchor bolts 2 are typically made of high-carbon steel or alloy steel, possessing high strength and toughness. To ensure a stable connection of anchor bolts 2, embedded parts in the wall must be pre-installed, and appropriate holes must be reserved for bolt fixing.

[0032] The rubber pad 3, located between the shear plate 1 and the anchor bolt 2, is primarily responsible for absorbing the vibration energy generated by dynamic loads. The thickness and elastic modulus of the rubber pad 3 are optimized to allow it to effectively deform and recover under dynamic loads, thus preventing damage to the connection due to severe vibrations. To ensure its energy absorption effectiveness, the rubber pad 3 may be made of a high-damping material, such as neoprene or silicone rubber. The reinforcing steel sleeve 4 is fitted over the anchor bolt 2 to improve the shear strength of the connection and reduce frictional slippage. The reinforcing steel sleeve 4 is filled with damping material, further enhancing the stability and durability of the connection. The combination of the reinforcing steel sleeve 4 and the damping material provides additional energy absorption capacity under dynamic loads, reducing wear and fatigue damage.

[0033] The seismic connection structure designed in this application aims to address the problem of unexpected frictional slippage at the connection points under dynamic loads, leading to shear strength loss and fatigue damage, through the coordinated action of the aforementioned components. Specifically, the shear plate 1, with its high-strength material and optimized design, reliably transmits and distributes shear force, ensuring the stability of the connection. The anchor bolts 2, through their secure connection to the wall, ensure the fixation effect of the shear plate 1. The rubber pad 3 acts as a buffer between the shear plate 1 and the anchor bolts 2, effectively absorbing the vibration energy brought by dynamic loads and preventing unexpected frictional slippage. The steel sleeve 4 not only improves shear strength but also further reduces frictional slippage and alleviates fatigue damage through its internal damping material. The overall design ensures the high performance of the connection structure under high dynamic loads, significantly improving the seismic resistance of the building structure.

[0034] In one embodiment, the shear plate 1 of the seismic connection structure of the building structure design of this application is made of high-strength alloy steel and has a multi-layered stacked structure. The joint surfaces between each layer are coated with an anti-slip coating to enhance their shear strength and reduce the risk of slippage. This multi-layered structure and anti-slip coating design can significantly improve the stability and load-bearing capacity of the shear plate 1 during earthquakes. The shear plate 1 is usually installed at critical connection points of the building structure, such as the nodes between beams and columns, or the junctions between floors and walls, to improve the overall seismic performance of the structure. The selection of high-strength alloy steel ensures the durability and toughness of the shear plate 1, while the multi-layered stacked structure further increases the rigidity and shear capacity of the shear plate 1.

[0035] In one embodiment, the multi-layer structure of the shear plate 1 can be achieved through mechanical pressing or welding. The anti-slip coating between each layer can be a high-performance resin-based material or a special metal oxide. These materials provide a high coefficient of friction between the contact surfaces, effectively reducing slippage of the shear plate 1 under external force. Specifically, the anti-slip coating can be uniformly applied to the contact surfaces of each layer of the shear plate 1 during the manufacturing process by spraying or rolling, ensuring a tight bond between the layers. For example, an electroplating process can be used to deposit the anti-slip material onto the surface of alloy steel, forming a uniform and dense anti-slip coating. This coating not only increases the shear strength of the shear plate 1 but also improves its corrosion resistance and service life.

[0036] In one embodiment, the shear plate 1 of the seismic-resistant connection structure of the building structure design of this application is provided with multiple reinforcing ribs 5. The direction of these reinforcing ribs 5 is perpendicular to the main direction of shear force, which not only improves the shear resistance of the shear plate 1, but also enhances the overall stability. Specifically, the design of the reinforcing ribs 5 ensures uniform stress distribution when subjected to external dynamic loads by arranging reasonable structural supports at key parts of the shear plate 1. The shear plate 1 is usually a planar structure, and its main function is to transfer lateral forces between various parts of the building, especially in sudden events such as earthquakes, where it can effectively absorb and disperse vibration energy.

[0037] In one embodiment, these reinforcing ribs 5 can be made of metal, specifically in the shape of strips or I-beams, and are installed on the surface of the shear plate 1 by welding or mechanical fixing. The spacing of the reinforcing ribs 5 is optimized according to the actual distribution of shear force to ensure that each part provides effective support and reinforcement. Furthermore, the number and location of the reinforcing ribs 5 also need to be calculated in detail to ensure their optimal distribution in the structure. For example, the concentrated areas of shear force can be determined using finite element analysis, and the number and density of reinforcing ribs 5 can be increased in these areas. Thus, in practical applications, even under strong vibrations, the overall stability and shear resistance of the structure can be maintained.

[0038] In one embodiment, a key feature of the seismic connection structure of this application's building structure design is that the anchor bolts 2 are prestressed high-strength bolts with an anti-corrosion coating on their surface. This design not only significantly improves the service life of the bolts but also ensures the connection reliability of the structure under dynamic load conditions. High-strength prestressed bolts have higher tensile strength and better ductility, enabling them to maintain the stability and safety of the connection under extreme conditions such as earthquakes. The anti-corrosion coating effectively resists the corrosive effects of the external environment on the bolts, extending the service life of the entire connection structure.

[0039] Specifically, prestressed high-strength bolts are typically installed at connection nodes between the main structure and additional components, such as beam-column joints or wall panel-foundation connections. The bolts are secured in the holes by preload, ensuring tight contact between structural components and load transfer. During installation, preload can be applied using hydraulic tensioning equipment to ensure sufficient clamping force in the connection node. The anti-corrosion coating on the bolts is usually made of zinc, aluminum, or stainless steel, effectively isolating them from moisture and corrosive substances in the air, thus ensuring stable performance during long-term use.

[0040] like Figure 2As shown, in one embodiment, the seismic connection structure of the building structure design of this application is characterized by a tapered transition section 6 at the head of the anchor bolt 2. This design can effectively reduce stress concentration at the bolt head under stress, prevent the risk of fracture due to high stress, and thus improve the overall stability and reliability of the connection. Specifically, the tapered transition section 6 at the head of the anchor bolt 2 gradually reduces the cross-sectional size, making the stress distribution of the bolt more uniform under high stress and avoiding excessive local stress. This improvement not only enhances the fatigue resistance of the bolt itself, but also ensures the durability of the entire connection node under strong earthquake conditions.

[0041] Specifically, the tapered transition section 6 is typically manufactured using precise machining or special processes. For example, during manufacturing, the bolt head can be precisely tapered-cut using a CNC machine tool to ensure that the shape and dimensions of the transition section meet design requirements. Furthermore, the mechanical properties of the tapered transition section 6 can be further optimized through material selection and heat treatment processes, thereby improving the seismic performance of the overall connection structure. In one specific embodiment, the tapered transition section 6 and the bolt body are made of the same material to ensure a match in their mechanical properties, thus achieving a reliable connection in practical applications.

[0042] In one embodiment, the seismic connection structure of the building structure design of this application uses a rubber pad layer 3 made of various composite materials, including damping materials and elastic materials. The selection of these materials aims to better absorb and disperse the vibration energy caused by external forces such as earthquakes, thereby reducing fatigue damage at the connection points. Specifically, the damping material of the rubber pad layer 3 can dissipate some energy through internal friction during vibration, while the elastic material provides sufficient restoring force, enabling the connection structure to quickly return to its initial state after being subjected to stress, ensuring the stability and durability of the structure. The selection and proportioning of the composite materials are precisely calculated to achieve optimal energy absorption.

[0043] For example, the rubber pad layer 3 can be designed with a layered structure to combine different materials, with each layer consisting of damping and elastic materials. These layers are tightly bonded together during the manufacturing process using a special adhesive process to form a whole. In practical applications, the rubber pad layer 3 is installed at critical locations in connection nodes, such as the connection between column bases and foundations or between beams and columns. Specifically, the shape and size of the rubber pad layer 3 are designed according to the specific structural requirements of the connection site to ensure that it can effectively absorb energy and dampen vibrations. In addition, the rubber pad layer 3 is also tightly bonded to surrounding metal connectors such as steel plates or anchor bolts to transmit forces and improve the overall connection performance.

[0044] In one embodiment, the rubber pad 3 of the seismic connection structure in this application has a thickness of 3-10 mm, and its thickness gradually increases outward from the center of the shear plate 1. This gradient design helps to create a more effective energy absorption effect, thereby more effectively reducing frictional slippage. This gradual thickness design of the rubber pad 3 can provide a more uniform stress distribution under seismic loads, enhancing the stability of the structure. At the same time, this design can also provide different degrees of buffering at different stress points, further improving the overall seismic performance of the structure.

[0045] The thickness variation of the rubber pad layer 3 can be achieved by precisely controlling the thickness of each layer during the rubber material processing. Specifically, during production, layered casting or molding methods can be used, adjusting the material filling amount in the mold to gradually thicken the rubber pad layer 3 from the center to the edge. This method not only ensures that the thickness variation of the rubber pad layer 3 meets the design requirements but also guarantees its stability and consistency throughout the entire connection structure. During installation, the rubber pad layer 3 is fixed between the shear plate 1 and the upper and lower structures, ensuring optimal energy absorption within the entire seismic connection structure.

[0046] Continue to refer to Figure 2 In one embodiment, the steel sleeve 4 of the seismic connection structure of this application is provided with a plurality of protruding structures 7. These protruding structures 7 are distributed on the inner wall of the steel sleeve 4 and contact the outer surface of the anchor bolt 2. The protruding structures 7 improve shear strength and connection stability by increasing the friction between the steel sleeve 4 and the anchor bolt 2. Specifically, the protruding structures 7 can be designed in a ring shape, strip shape or irregular shape, and can be adjusted according to actual needs to adapt to different application scenarios.

[0047] The contact surface between the protruding structure 7 of the reinforcing steel sleeve 4 and the outer surface of the anchor bolt 2 can be refined to ensure a tighter contact. For example, when machining several protrusions on the inner wall of the reinforcing steel sleeve 4, this can be achieved through machining, cold drawing, or heat treatment. Furthermore, the spacing and height of the protruding structures 7 should be optimized according to the specific requirements of the seismic connection to ensure the stability and reliability of the connection structure under external forces such as earthquakes. This approach not only enhances the rigidity of the connection structure but also effectively disperses stress, improving the overall seismic performance of the structure.

[0048] In one embodiment, a small gap 8 is reserved between the steel sleeve 4 and the anchor bolt 2 in the seismic connection structure of the building structure design of this application. This gap is filled with high-strength cement grout to form a stable whole, preventing loosening and displacement during long-term use. This design provides additional stability to the connection parts of the building structure, especially under natural disaster conditions such as earthquakes, effectively reducing the risk of loosening and detachment at the connection. The steel sleeve 4 is typically installed in pre-embedded parts of precast components or cast-in-place concrete, while the anchor bolt 2 passes through the steel sleeve 4 and connects to other parts of the building, forming a stable fixing point.

[0049] Specifically, the minute gap 8 between the rebar sleeve 4 and the anchor bolt 2 is usually achieved through precision machining or pre-set molds. For example, the position of the rebar sleeve 4 can be pre-set during the prefabrication process to ensure that it maintains a certain distance from the anchor bolt 2. In the actual installation process, the anchor bolt 2 is first inserted into the rebar sleeve 4, and then high-strength cement grout is injected from the bottom of the sleeve using specialized grouting equipment until it fills to the top of the sleeve. During this process, the grouting pressure and speed need to be controlled to ensure that the cement grout fully fills the gap and removes air, ultimately making the rebar sleeve 4 and the anchor bolt 2 a tightly integrated whole.

[0050] In one embodiment, the seismic connection structure of this application's building structure design includes an annular sealing ring 9 on the outside of the rebar sleeve 4. This annular sealing ring 9 is tightly fitted against the shear plate 1, effectively preventing external moisture from seeping into the connection area, thereby extending the structure's service life. The rebar sleeve 4 is an important component for connecting and fixing rebars, typically made of high-strength steel with excellent tensile and compressive strength. To ensure the long-term stability and reliability of the rebar sleeve 4 in harsh environments, the designer adds an annular sealing ring 9 to its exterior. The annular sealing ring 9 is typically made of weather-resistant and elastic materials, such as rubber or silicone, capable of maintaining good sealing performance under different environmental conditions.

[0051] The outer diameter of the annular sealing ring 9 matches the outer diameter of the reinforcing sleeve 4, while its inner diameter is slightly larger than the contact surface width of the shear plate 1, allowing it to fit tightly against the shear plate 1. During actual installation, the annular sealing ring 9 is first fitted onto the outside of the reinforcing sleeve 4, and its firm attachment is ensured by adhesive or other fixing methods. When the reinforcing sleeve 4 is inserted into the designated position and contacts the shear plate 1, the annular sealing ring 9 will tightly adhere to the surface of the shear plate 1, forming an effective waterproof barrier to prevent external moisture from entering the connection. Furthermore, this design can improve the overall seismic performance of the structure, as the sealing ring can absorb and disperse stress caused by seismic loads to a certain extent, enhancing the stability of the connection. For example, during installation, a groove can be pre-machined on the shear plate 1 to better fix the annular sealing ring 9, ensuring a more secure fit against the surface of the shear plate 1.

[0052] In one embodiment, the thickness of the rubber pad 3 in the seismic connection structure of the building structure design of this application is greater than the thickness of the reinforcing steel sleeve 4. This design ensures that when the building is subjected to external forces such as earthquakes, the rubber pad 3 can function first, absorbing most of the energy, thereby reducing the direct impact at the connection point. The rubber pad 3 is typically installed between two main building components, such as the connection between a beam and a column, or the connection between a precast slab and a wall. Its thickness can be adjusted according to actual working conditions and design requirements, but it must always be greater than the thickness of the reinforcing steel sleeve 4.

[0053] The reinforcing steel sleeve 4 is used to fix the reinforcing steel, ensuring the overall stability of the connection structure. The rubber pad 3 and the reinforcing steel sleeve 4 can be connected in various ways, such as by adhesives or mechanical fasteners. The specific connection method must ensure that the rubber pad 3 can deform freely under stress without affecting its energy absorption function. For example, anti-slip layers can be added to the upper and lower surfaces of the rubber pad 3 to increase friction between it and building components, preventing displacement due to external impacts. Thus, through reasonable structural design, the connection structure can effectively absorb and disperse energy when subjected to external forces, thereby protecting the overall stability and safety of the building.

[0054] In one embodiment, such as Figure 3As shown, the damping material of the seismic connection structure in this application uses high-performance damping alloy powder 10, which is uniformly distributed inside the steel sleeve 4, thereby significantly improving the overall vibration reduction effect and connection reliability, and reducing fatigue damage caused by vibration. The steel sleeve 4 plays a role in transmitting and dispersing stress in the structural connection node. By adding high-performance damping alloy powder 10 to it, the energy caused by external forces such as earthquakes can be effectively absorbed and consumed, reducing the structural response under dynamic action. The uniform distribution of this material ensures that all parts of the connection have the same vibration reduction capacity, thereby avoiding the risk of local stress concentration and premature failure.

[0055] Specifically, high-performance damping alloy powder 10 is uniformly filled into the interior of the rebar sleeve 4 using a specific process. For example, it can be uniformly dispersed and fixed to the inner wall of the rebar sleeve 4 by high-pressure gas blowing or vibration filling. The rebar sleeve 4 is typically made of high-strength steel, possessing sufficient strength and stiffness to ensure the overall stability of the connection structure. In this case, the addition of high-performance damping alloy powder 10 not only provides excellent vibration reduction performance but also further enhances the connection strength and durability between the rebar sleeve 4 and the structural components.

[0056] In practical operation, when this device is used, its main purpose is to enhance the seismic performance of the building structure and ensure the stability and safety of the building under dynamic loads such as earthquakes. Specifically, when a building is affected by an earthquake or similar dynamic loads, the shear plate 1 first assumes the role of transmitting and dispersing shear force, ensuring that the shear force is evenly distributed in different parts of the building, rather than concentrated at a certain point, thereby preventing structural damage due to local stress concentration. At the same time, the anchor bolts 2 are connected to the wall embedded parts through their threads, firmly fixing the shear plate 1, so that the shear plate 1 and the wall form a stable whole, ensuring the stability and reliability of the connection structure. The rubber pad 3 is located between the shear plate 1 and the anchor bolts 2. Under dynamic loads, the rubber pad 3, due to its elasticity and vibration absorption characteristics, can effectively absorb the vibration energy generated by the dynamic loads, reduce and weaken the impact of seismic waves on the building structure, and further improve the seismic resistance of the building. To enhance the seismic effect, the thickness and elastic modulus of the rubber pad 3 are optimized to effectively absorb energy under dynamic loads and prevent unexpected frictional slippage. Furthermore, the reinforcing steel sleeve 4, fitted over the anchor bolt 2, also plays a crucial role. The reinforcing steel sleeve 4 not only enhances the shear strength of the connection, reducing slippage caused by excessive shear force, but also, due to its internal damping material, further reduces frictional slippage and structural fatigue damage caused by vibration, extending the building's service life and safety performance. This series of designs and configurations ensures that the seismic-resistant connection structure of the building structure maintains efficient operation even under extreme conditions such as strong earthquakes, significantly improving the building's seismic resistance and safety.
