Description

Technical Field

[0001] This invention relates to the field of building structure connection technology, and in particular to a spring-loaded beam-column connection structure and method. Background Technology

[0002] In building construction, beam-column connections are a core component, as their stability and installation efficiency directly impact the safety and construction progress of the entire structure. Currently, existing beam-column connection methods mainly include welding, bolting, and mortise and tenon joints.

[0003] While welding offers strong rigidity and stability, it suffers from drawbacks such as frequent wet work on-site, low construction efficiency, and welding quality heavily influenced by the skill level of the workers. Furthermore, it cannot be disassembled after welding, hindering future maintenance, modification, or recycling. Bolted connections are relatively convenient to install and can be disassembled, but they require a large number of bolts, nuts, and other components, which must be tightened one by one during installation, making the process cumbersome. Moreover, bolts are prone to loosening after long-term use, affecting the reliability of the connection. Traditional mortise and tenon connections, while requiring no additional components, demand extremely high processing precision and accurate alignment during assembly. Additionally, mortise and tenon structures are susceptible to loosening and damage after being subjected to external impacts, making repair difficult.

[0004] In addition, existing detachable beam-column connection structures mostly adopt simple snap-fit ​​methods. The snap-fit ​​parts have no pre-tightening force, which makes them prone to displacement and shaking after connection. Moreover, the snap-fit ​​structure is mostly a straight groove design, which has poor limiting effect after snap-fit ​​and cannot effectively limit the vertical and horizontal displacement of beams and columns, making it difficult to meet the load-bearing requirements of building structures.

[0005] In view of the shortcomings of the existing technology, there is an urgent need for a beam-column connection structure that is simple in structure, easy to process, efficient in installation, reliable in connection, quick to disassemble, and has good limiting effect, so as to solve the problems existing in the existing technology. Summary of the Invention

[0006] The purpose of this invention is to provide a spring-loaded beam-column connection structure and method, which solves the problems of cumbersome installation, poor connection reliability, poor limiting effect, and poor disassembly in existing beam-column connection structures.

[0007] To achieve the above objectives, the present invention provides a spring-loaded beam-column connection structure, comprising a connected structural column and a structural beam. One end of the structural beam connected to the structural column is provided with an insertion end, and an elastic locking component is provided on the insertion end. One end of the structural column is provided with a main groove, and a limiting component is provided in the main groove. The limiting component and the elastic locking component are adapted to each other. A receiving component is also provided inside the main groove.

[0008] Preferably, multiple reinforcing plates are provided on both sides of the structural beam.

[0009] Preferably, a plurality of insertion holes are provided on the outer side of the end of the structural column, and the insertion holes are connected to the limiting component.

[0010] Preferably, the insertion end is configured as a frustum structure, and each side of the insertion end is provided with a mounting hole.

[0011] Preferably, the surface of the insertion end is treated with rust removal, polishing, or roughening.

[0012] Preferably, the elastic locking assembly includes an elastic element, one end of which is fixedly connected to the mounting hole, and the other end of which is fixedly connected to a pop-out block, the edge of which is rounded.

[0013] Preferably, the depth of the main groove is the same as the height of the insertion end, and the width and length of the main groove are greater than the width and length of the insertion end.

[0014] Preferably, the limiting component includes a receiving groove formed on the side of the main groove, the receiving groove being adapted to the structure of the pop-out block; The receiving groove is connected to the insertion hole.

[0015] Preferably, the receiving component includes a second elastic element disposed at the bottom surface of the main groove, and at least one second elastic element is provided; One end of the second elastic element is fixedly connected to the main groove, and the other end of the second elastic element abuts against the insertion end.

[0016] A method for a spring-loaded beam-column connection structure includes the following steps: S1. During installation, suspend the structural beam and bring it close to the structural column. The four pop-out small blocks on the insertion end are squeezed by the side of the main groove. When the elastic element is compressed, the pop-out small blocks are retracted into the installation hole of the insertion end. S2. Align the insertion end of the structural beam with the main groove of the structural column and slowly push it in to the designed depth. The main groove will no longer squeeze out the small piece. The elastic element one will automatically pop out under its own elastic force, pushing the popped-out small piece into the receiving groove on the side of the main groove. The elastic element two will press against the insertion end to realize the positioning and connection of the structural beam and the structural column. S3. When disassembling, insert the unlocking pin into the insertion hole, press the unlocking pin to pop out the small piece, so that the elastic element is compressed and the pop-out small piece retracts. Pull the insertion end out of the main groove to achieve quick disassembly.

[0017] Therefore, the present invention, employing the above-mentioned spring-loaded beam-column connection structure and method, has the following beneficial effects: (1) Efficient and convenient installation: This structure does not require welding or individual bolt tightening. The small blocks are automatically engaged with the receiving groove by the drive of the elastic element, which realizes the rapid positioning and connection of beams and columns, greatly shortens the construction time, reduces the labor intensity of workers, and is especially suitable for the rapid construction of prefabricated buildings.

[0018] (2) Reliable connection and good limiting effect: The second elastic element of this application provides a continuous pre-tightening force, so that the pop-out small block fits tightly with the receiving groove. The receiving groove of the truncated pyramid structure can effectively prevent the pop-out small block from falling out in the opposite direction and limit the vertical and horizontal displacement of the structural beam and structural column. At the same time, the second elastic element at the bottom of the main groove applies a top-tightening force to the insertion end, so that the insertion end is tightly connected with the inner wall of the main groove, eliminating the connection gap and avoiding loosening and shaking after connection. The double elastic element greatly improves the connection stability and load-bearing capacity, and meets the safety requirements of the building structure.

[0019] (3) Good disassembly: When disassembling this structure, you only need to press the pop-out small piece to pull out the structural beam. The operation is simple and does not require damage to the beam and column structure. It is convenient for later maintenance and modification. At the same time, it realizes the recycling of structural components, which is in line with the green building concept and reduces construction and maintenance costs.

[0020] (4) Simple structure and easy processing: The core structure of this structure only includes the insertion end, elastic element, pop-out block and receiving groove. The number of parts is small, the processing technology is simple, and there is no need for extremely high processing precision, which can reduce processing costs and facilitate mass production and application.

[0021] (5) Wide applicability: This structure is applicable to various types of beam-column connections such as steel structure and concrete structure, and can be adapted to structural beams and columns with different cross-sectional dimensions. The spring specifications, frustum angle and component dimensions can be adjusted according to actual stress requirements. Applicable scenarios include prefabricated buildings, temporary buildings, small factories, etc.

[0024] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Example Please see Figures 1-5 This invention provides a spring-loaded beam-column connection structure, comprising a connected structural column 1 and a structural beam 2. Multiple reinforcing plates 21 are provided on both sides of the structural beam 2 to enhance its strength. An insertion end 3 is provided at the end of the structural beam 2 connecting to the structural column 1, and an elastic locking component is provided on the insertion end 3. A main groove 5 is formed at one end of the structural column 1, the size of which is adapted to the insertion end 3. A limiting component is provided within the main groove 5, and the limiting component is adapted to the elastic locking component. A receiving component is also provided within the main groove 5 to provide preload force.

[0027] Several insertion holes 11 are provided on the outer side of the end of the structural column, and the insertion holes 11 are connected to the limiting component. By inserting the unlocking pin into the insertion hole 11, the small piece 42 is squeezed out and retracted into the mounting hole 31, thereby separating the structural beam 2 and the structural column 1 and completing the disassembly.

[0028] The insertion end 3 is designed as a truncated pyramid structure. The length, width, and thickness of the insertion end 3 are determined according to the cross-sectional dimensions and stress requirements of the structural beam 2 and structural column 1, ensuring a tight fit with the main groove 5 after insertion without any obvious gaps. The insertion end 3 is made of the same material as the beam (e.g., the same type of steel for steel structures and the same strength grade of concrete for concrete structures), and the surface is treated with rust removal, grinding, or roughening to enhance the friction of the connection surface.

[0029] The elastic locking assembly includes an elastic element 41, one end of which is fixedly connected to the mounting hole 31. The connection method, such as welding, bolting, or snap-fit, is determined by the material. The other end of the elastic element 41 is fixedly connected to a pop-out block 42. The pop-out block 42 has a cubic structure with a smooth surface and rounded edges to prevent jamming during installation. Its dimensions are compatible with the limiting assembly, and it is made of high-strength, wear-resistant material to ensure it is not easily deformed or damaged during long-term use. Figure 3 As shown, in this embodiment, the elastic element 41 is a spring, and four springs and four pop-out blocks 42 are provided. The elastic locking assembly can be quickly disassembled, which is convenient for later maintenance, modification and recycling, and solves the problems of cumbersome installation, poor positioning, poor disassembly and loose connection of the existing connection structure.

[0030] The depth of the main groove 5 is the same as the height of the insertion end 3, and the width and length of the main groove 5 are slightly larger than the width and length of the insertion end 3. The sides of the main groove 5 are flat and smooth, without burrs or protrusions, to ensure that the insertion end 3 can be inserted smoothly.

[0031] The limiting component includes a receiving groove 61 formed on the side of the main recess 5, which is adapted to the structure of the pop-out block 42. The receiving groove 61 communicates with the insertion hole 11. Figure 5 As shown, four receiving slots 61 are provided. The transition of the receiving slots 61 has no sharp edges or corners, ensuring that the pop-out small piece 42 can be smoothly inserted and firmly attached, thus achieving reliable positioning.

[0032] The receiving component includes a second elastic element 71 disposed on the bottom surface of the main groove 5, and at least one second elastic element 71 is provided. One end of the second elastic element 71 is fixedly connected to the main groove 5, and the other end of the second elastic element 71 abuts against the insertion end 3. In this embodiment, the second elastic element 71 is a spring. When the insertion end 3 is fully pushed into the main groove 5, the spring is in a compressed state, applying a continuous pressing force to the insertion end 3, so that the insertion end 3 fits tightly against the inner wall of the main groove 5, further improving the tightness and stability of the connection, and avoiding shaking caused by gaps in the connection.

[0033] A method for a spring-loaded beam-column connection structure includes the following steps: S1. During installation, the structural beam 2 is suspended and brought close to the structural column 1. The four pop-out small blocks 42 on the insertion end 3 are squeezed by the side of the main groove 5, the elastic element 41 is compressed, and the pop-out small blocks 42 are retracted into the mounting hole 31 of the insertion end 3. S2. Align the insertion end 3 of the structural beam 2 with the main groove 5 of the structural column 1, and slowly push it in to the designed depth. The main groove 5 no longer squeezes out the pop-out small piece 42. The elastic element 1 41 automatically pops out under its own elastic force, pushing the pop-out small piece 42 into the receiving groove 61 on the side of the main groove 5. The elastic element 2 71 presses against the insertion end 3, realizing the positioning and connection of the structural beam 2 and the structural column 1. S3. When disassembling, insert the unlocking pin into the insertion hole 11, press the unlocking pin to pop out the small block 42, compress the elastic element 41, retract the small block 42, and pull the insertion end 3 out of the main groove 5 to achieve quick disassembly.

[0034] Therefore, the present invention adopts the above-mentioned spring-loaded beam-column connection structure and method, which can realize the rapid positioning and reliable connection of structural beams and structural columns, taking into account both installation efficiency and connection stability, while having good disassembly, facilitating later maintenance, modification and recycling, and reducing construction and maintenance costs.

[0035] 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 preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
