Description

Technical Field

[0001] This utility model provides an anti-seismic wedge plug, belonging to the technical field, and particularly relates to a novel anti-seismic wedge plug for beam-column connections in building frame structures. Background Technology

[0002] In the field of building engineering, beam-column connection structures are a key component of building frame systems, and their performance directly affects the overall stability and safety of the building. Beam-column connection structures are primarily used to achieve reliable connections between beams and columns, enabling them to work together to bear loads and ensuring the structural integrity of the building during daily use and in the event of natural disasters such as earthquakes.

[0003] Existing beam-column connection structures mostly employ traditional rigid connection methods, such as welding and bolting. These structures primarily consist of connectors embedded in the beams and columns, along with auxiliary reinforcement components, directly fixing the beams and columns together. However, under seismic loads, this rigid connection lacks effective buffering and force dispersion mechanisms. The energy generated by the earthquake tends to concentrate at the connection points, leading to excessive stress, deformation, and fracture, severely impacting the building's seismic performance. Furthermore, traditional connection structures are limited in form, making it difficult to flexibly adjust seismic resistance according to different seismic conditions, and they cannot effectively supplement or enhance the connection strength after installation. Utility Model Content

[0004] In order to solve the above problems, this application provides a novel seismic-resistant wedge-shaped plug for beam-column connections in building frame structures, which solves the problems of poor seismic resistance, stress concentration and unstable connection of traditional beam-column connections, and significantly improves the seismic resistance of buildings.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel anti-seismic wedge plug for beam-column connection in a building frame structure, comprising a beam connection component, a column connection component, and an anti-seismic wedge plug body;

[0006] The beam connecting component is in the shape of a long strip block, with a connecting groove at the top that is adapted to the beam for connecting with the beam of the building frame;

[0007] The column connecting member is a vertical strip with a connecting structure on the side that is adapted to the column for connecting with the column of the building frame.

[0008] The seismic-resistant wedge insert body is a wedge-shaped structure, and its shape is adapted to the installation space between the beam connection component and the column connection component. It can be installed between the beam connection component and the column connection component from different positions. Through the wedge-shaped structure, when the building is subjected to earthquake, the relative sliding and squeezing force of the wedge surface is used to achieve a more efficient seismic resistance effect.

[0009] Preferably, the beam connecting member is provided with a limiting protrusion for limiting the seismic wedge insert body, and the column connecting member is provided with a limiting groove adapted to the limiting protrusion. When the seismic wedge insert body is installed, the limiting protrusion is embedded in the limiting groove to assist in positioning and enhance connection stability.

[0010] Preferably, the wedge angle of the anti-seismic wedge plug body is 90°-120°.

[0011] Preferably, the beam connecting components, column connecting components, and seismic wedge insert bodies are made of high-strength alloy materials for construction, possessing good strength and toughness to meet seismic requirements and the stress requirements of building structures.

[0012] Preferably, one side of the anti-seismic wedge plug body and the beam connecting component are connected to a reinforcement member through an expansion groove, and the reinforcement member is installed inside the expansion groove through several blocking tabs.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0014] This device is used for connecting beams and columns in building frames. Its principle is to connect beams using connecting grooves in the beam connection components and columns using connecting structures in the column connection components, thus constructing a basic connection. The seismic-resistant wedge-shaped insert body adapts to the installation space in a wedge shape. During an earthquake, the wedge surface slides and compresses to disperse and buffer the force. Limiting protrusions and grooves assist in positioning and stabilization. The 90°-120° wedge angle optimizes force transmission. High-strength alloy ensures strength and toughness. Expansion grooves, reinforcement components, and blocking panels strengthen the connection. Its advantages include: a wedge-shaped structure for more efficient seismic resistance; multi-component collaboration to ensure connection stability; optimized force transmission and structural durability through angle and material selection; and further enhanced overall strength through expansion and reinforcement. This effectively enhances the seismic performance of beam-column connections in building frames, reduces the risk of earthquake damage to building structures, and improves building safety and stability.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] like Figure 1 and Figure 2As shown, a novel seismic-resistant wedge-shaped insert for beam-column connections in a building frame structure includes a beam connection component 1, a column connection component 2, and a seismic-resistant wedge-shaped insert body 3. The beam connection component 1 is elongated, with its top connected to the beam via a connecting groove 4. The column connection component 2 is vertically elongated, with its side connected to the column via a connecting structure 5. The seismic-resistant wedge-shaped insert body 3 is wedge-shaped, adaptable to the installation space 6 between beams and columns, allowing for installation in multiple positions. Its wedge shape enables efficient seismic resistance through sliding and compressive forces. The beam section has a limiting protrusion 7, and the column section has an adaptable limiting groove 8, assisting in the positioning and stabilization of the insert body. The wedge angle of the insert body is 90°-120°. All three components are made of high-strength alloy, ensuring both strength and toughness. Simultaneously, the insert body and one side of the beam section are connected to a reinforcement component 10 via an expansion groove 9. The reinforcement component is installed within the expansion groove via a blocking tab, enhancing the overall connection performance.

[0026] In this implementation scheme, the beam connecting member 1 is tightly fitted to the beam body through the top connecting groove 4, and the side connecting structure 5 of the column connecting member 2 is stably connected to the column body, forming the basic framework for the beam-column connection. The seismic wedge insert body 3, with its unique wedge structure, can be flexibly embedded from different positions within the installation space 6. During an earthquake, relative sliding and compressive forces are generated between the wedge surfaces, dispersing and buffering the seismic force and preventing stress concentration at the beam-column connection. The cooperation between the limiting protrusion 7 and the limiting groove 8 precisely positions the seismic wedge insert body 3 during installation and limits its excessive displacement during vibration, further enhancing connection stability. The wedge angle of the seismic wedge insert body 3, set at 90°-120°, has been verified through mechanical calculations and actual testing. This angle range ensures the structural strength of the insert body when transmitting loads and optimizes the transmission path of seismic forces, improving seismic resistance. High-strength alloy materials are used to manufacture all components to ensure that material failure does not occur when subjected to large loads and seismic impacts, guaranteeing the reliability of the structure. The combination of expansion slot 9 and reinforcement component 10, through the installation of the blocking page within expansion slot 9, allows for additional reinforcement of the beam-column connection as needed, further enhancing the overall connection performance. These components work together synergistically to address the shortcomings of traditional beam-column connections in terms of seismic resistance. The innovative application of wedge-shaped structures and multiple reinforcement designs to beam-column connections not only improves the seismic resistance of the building structure but also enhances its overall stability and durability, significantly improving the building's safety during earthquakes.

[0027] like Figure 3 and Figure 4As shown, this novel seismic-resistant wedge-shaped insert for beam-column connections utilizes the collaborative work of beam connection component 1, column connection component 2, and the seismic-resistant wedge-shaped insert body 3. The beam is connected to the beam via connecting groove 4, and the column via connecting structure 5. The wedge-shaped insert body 3 adapts to the installation space 6, allowing for multi-position installation. During earthquakes, its wedge shape enables efficient seismic resistance through sliding and compression. Limiting protrusions 7 and grooves 8 assist in positioning and stabilization, while the 90°-120° wedge angle optimizes seismic force transmission. High-strength alloy material ensures strength and toughness. Furthermore, the expansion groove 9, in conjunction with the reinforcement component 10 and the blocking flap, further strengthens the connection, enabling the insert to comprehensively improve the seismic performance and stability of the beam-column connection under seismic requirements, from structural adaptation and material selection to additional reinforcement.

[0028] In this implementation plan, during the actual use of this device, it is necessary to combine the pre-embedded process in existing building construction technology. Before pouring the concrete for the beams and columns, the beam connecting component 1 and the column connecting component 2 are fixed to the corresponding steel reinforcement frame using pre-embedded bolts to ensure accurate positioning. Simultaneously, existing building welding technology is used to fully weld and reinforce the key parts of the connecting groove 4 to the beam and the connecting structure 5 to the column, enhancing the initial connection strength. The seismic wedge-shaped insert body 3, the beam connecting component 1, and the column connecting component 2 can be made of Q345B low-alloy high-strength structural steel. This material has a yield strength of 345MPa and a tensile strength of 470-630MPa, combining high strength with good plasticity and toughness, effectively coping with seismic loads. When installing the seismic-resistant wedge insert body 3, existing construction hoisting equipment, such as a small crawler crane, must be used to precisely control the installation angle and position of the insert, ensuring that its wedge surface fits tightly against the contact surfaces of the beams and columns. During the installation of the reinforcement 10, existing bolt fastening technology is used to reliably connect the blocking page to the expansion slot 9 and the reinforcement 10 with high-strength bolts (such as grade 8.8 bolts), further enhancing the overall structural performance. After construction, existing building inspection technologies, such as ultrasonic flaw detectors, are used to perform non-destructive testing on the welded areas to ensure that the connection quality meets the seismic design requirements, ultimately forming a complete and reliable seismic connection system for the building frame beams and columns.

[0029] Specifically, in implementing this plan, firstly, during the reinforcement binding stage of the building frame beams and columns, existing building construction positioning technology will be used. A total station will be used for precise measurement and layout to determine the pre-embedded positions of beam connection component 1 and column connection component 2. Using existing reinforcement welding techniques, the anchoring reinforcement of the connection components will be double-lapped with the main reinforcement of the beams and columns, with a weld length of not less than 5d (d being the diameter of the anchoring reinforcement), ensuring a stable connection between the connection components and the reinforcement cage. During concrete pouring, existing concrete vibration equipment, such as immersion vibrators, will be used. During vibration, direct contact between the vibrator and the connection components will be avoided to prevent displacement.

[0030] Before installing the seismic wedge insert body 3, the connecting groove 4 of the beam connecting component 1, the connecting structure 5 of the column connecting component 2, and the limiting groove 8 need to be cleaned. Existing high-pressure air blowing equipment is used to remove surface dust and debris. The seismic wedge insert body 3 is hoisted using an electric hoist and special lifting tools. According to the wedge angle requirement of 90°-120° in the construction drawings, the installation angle of the insert is monitored in real time by a total station. The wedge surface is slowly adjusted to fit the corresponding surface of the beam and column connecting components. After the limiting protrusion 7 is embedded in the limiting groove 8, the high-strength bolts between the insert and the connecting components are tightened using an existing torque wrench. The tightening is performed in two stages: initial tightening and final tightening, according to the design torque value. The initial tightening torque is 50% of the final tightening torque, and the final tightening torque is determined according to the bolt specifications and seismic design requirements to ensure a tight connection.

[0031] For the installation of the reinforcement 10, bolt holes are machined at the corresponding positions in the expansion slot 9 and the reinforcement 10 using existing bench drill equipment, and the bolt holes are tapped using an existing tapping machine. The reinforcement 10 is then inserted into the expansion slot 9 through the retaining plate, and the matching hex bolts are installed using an electric screwdriver, and tightened step by step in a symmetrical and crisscrossing order, so that the reinforcement 10, the beam connecting component 1, and the seismic wedge insert body 3 form a stable whole.

[0032] After construction is completed, existing building structure testing technology is used to check for cracks at each connection point using a crack width gauge, and a digital pull-out tester is used to test the anchorage strength of the connecting components. A dynamic strain gauge is used to monitor the strain at the beam-column connection point under simulated seismic loads to ensure that the seismic performance of this device meets the design requirements.

[0033] It should be noted that under seismic loads, this device achieves high-efficiency earthquake resistance through its unique structural design. When the building frame is subjected to seismic force F, the connecting groove 4 at the top of the beam connecting member 1 is tightly fitted with the beam, and the connecting structure 5 on the side of the column connecting member 2 is stably connected to the column, forming a stable foundation force transmission path.

[0034] The wedge-shaped structure of the seismic-resistant wedge insert body 3 is adapted to the installation space 6 between beams and columns. According to the wedge force principle, when the seismic force F acts on the wedge surface, it will be decomposed into a normal force FN perpendicular to the wedge surface and a frictional force Ff parallel to the wedge surface, where FN = sinθ / F_seismic (θ is the wedge angle, ranging from 90° to 120°), and Ff = μFN (μ is the coefficient of friction). A reasonable wedge angle keeps the normal force FN within a certain range, which can both dissipate seismic energy through compression between the wedge surfaces and avoid excessive pressure leading to structural damage; the frictional force Ff prevents excessive sliding of the wedge insert body 3, ensuring connection stability.

[0035] The cooperation between the limiting protrusion 7 and the limiting groove 8 further restricts the displacement of the plug-in, enhancing the overall structural integrity. The limiting force Flimiting provided by the protrusion can assist in resisting seismic forces, ensuring that the total resistance Ftotal = Ff + Flimiting. Simultaneously, the high-strength alloy material ensures that the component does not undergo plastic deformation when subjected to large FN and Fseismic forces. The reinforcement structure composed of the expansion groove 9, the reinforcement member 10, and the blocking leaf can increase the additional shear resistance Freinforcement, ultimately achieving Ftotal + Freinforcement ≥ Fseismic, effectively dispersing and dissipating seismic forces, thereby ensuring the safety of beam-column connections under seismic loads and significantly improving the seismic performance of the building frame.

[0036] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
