Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a building steel structure connection component. Background Technology

[0002] In the field of modern architecture, steel structures have become the core structural form for large and high-rise buildings due to their advantages such as high strength, light weight, and short construction period. I-beams, as an important component of steel structures, possess excellent bending resistance and stability due to their unique cross-sectional shape and are widely used in key load-bearing components such as beams and columns. However, due to limitations in transportation and construction techniques, actual projects often require the joining of multiple I-beam sections to meet the length and load-bearing requirements of the building structure.

[0003] Currently, I-beams are usually joined by welding, which involves melting the metal at high temperatures to connect the I-beams into one piece. Although the connection strength is high, if the structure needs to be dismantled later due to changes in building function, structural maintenance, or renovation, cutting equipment is required to destroy the weld. This is not only complicated and inefficient, but also easily damages the I-beam base material, affecting its reuse. Utility Model Content

[0004] While connecting I-beams by melting metal at high temperatures results in high connection strength, subsequent disassembly due to changes in building function, structural maintenance, or renovation requires cutting equipment to damage the welds. This is not only complex and inefficient but also prone to damaging the I-beam base material, affecting its reuse. This invention provides a building steel structure connection component that has the advantages of high connection strength and easy disassembly, solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a building steel structure connection component, including two I-beams, with connecting parts provided at corresponding positions of the two I-beams, and fastening screws installed on both sides of the corresponding positions of the two I-beams. Nuts are threaded onto the upper ends of the fastening screws. A driving cavity is provided inside the connecting part, and a conical block is provided inside the driving cavity. An adjusting screw is rotatably installed on the top of the conical block, extending to the outer side of the upper end of the connecting part. Trapezoidal blocks are symmetrically arranged on both sides of the conical block. A slider is fixedly installed on the inclined surface of each of the two trapezoidal blocks. A slide rail is provided on the inclined surface of each of the two sides of the conical block. The conical block is slidably installed inside the slide rail on the inner side of the two trapezoidal blocks via the slider. L-shaped limiting plates are fixedly installed on both sides of each of the two trapezoidal blocks, and U-shaped slots are provided on the inner sides of each of the two L-shaped limiting plates.

[0006] Preferably, the arc surface inside the U-shaped groove is adapted to the size of the fastening screw, and the connection between the surface of the adjusting screw and the upper end of the connector is a threaded connection.

[0007] By adapting the internal arc surface of the U-shaped slot to the size of the fastening screw, a tight fit can be formed with the screw to create a stable limit, thereby improving the reliability of the connection.

[0008] Preferably, mounting holes are symmetrically provided on both sides of the connection between the two I-beams, the fastening screw passes through the mounting hole and is threadedly connected to the nut, and a handle is fixedly installed on the top of the adjusting screw, and a fastening hole is provided on the top of the handle.

[0009] The handle facilitates the application of force to rotate the adjusting screw, and the fastening hole at the top of the handle allows for the connection of external tightening tools such as electric wrenches, enabling rapid mechanized rotation of the adjusting screw, significantly improving installation and disassembly efficiency and reducing manual labor intensity.

[0010] Preferably, the connector has symmetrical slots on both sides, the slots are adapted to the end face of the I-beam, and the I-beam is installed inside the connector by inserting it into the slot.

[0011] By symmetrically opening slots on both sides of the connector to fit the end face of the I-beam, the I-beam and the connector can be quickly and accurately inserted and positioned, providing a stable foundation for subsequent fastening and improving assembly efficiency.

[0012] Preferably, when the I-beam is inserted into the connector, the middle part of the fastening screw corresponds to the U-shaped groove, and two sliding grooves are symmetrically opened on both sides of the connector, and the L-shaped limiting plates on both sides of the trapezoidal block are slidably installed in the sliding grooves.

[0013] By using the sliding grooves on both sides of the connector, the L-shaped limiting plates on both sides of the trapezoidal block can slide stably along the sliding grooves, ensuring that the L-shaped limiting plates drive the U-shaped slots to accurately align with the middle of the fastening screw, thereby improving the stability and reliability of the connection process.

[0014] Preferably, the inclined surface at the bottom of the conical block is tangent to the inner inclined surface of the trapezoidal block. When the conical block moves upward along the slide rail, the two trapezoidal blocks move closer to each other, and at the same time, the fastening screw is connected to the inside of the U-shaped slot.

[0015] This utility model has the following advantages:

[0016] By setting up a cooperative structure of driving cavity, conical block, trapezoidal block and L-shaped limiting plate inside the connector, when the adjusting screw is rotated, the threaded connection causes the adjusting screw to drive the conical block to move upward along the slide rail. Since the bottom inclined surface of the conical block is tangent to the inner inclined surface of the trapezoidal block, when the conical block moves upward, the two trapezoidal blocks move closer to each other along the slide rail through the cooperation of the slide rail and the slide groove, thereby driving the L-shaped limiting plates on both sides to move synchronously, so that the U-shaped slot forms a ring-shaped limiting on the middle of the fastening screw, realizing the quick fastening connection between the I-shaped steel and the connector, avoiding the disadvantage of traditional welding that requires cutting and damage. When disassembling, simply rotate the adjusting screw in the opposite direction to separate the trapezoidal block to release the limiting, which is convenient and efficient.

[0025] 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.

[0026] Please see Figures 1-6A building steel structure connection component includes two I-beams 1, with connectors 2 at corresponding positions of the two I-beams 1, and fastening screws 5 installed on both sides of the corresponding positions of the two I-beams 1, with nuts 6 threaded onto the upper end of the fastening screws 5.

[0027] The connector 2 has a drive cavity 7 inside, and a conical block 11 is provided inside the drive cavity 7. An adjusting screw 8 is rotatably mounted on the top of the conical block 11. The adjusting screw 8 extends to the outer side of the upper end of the connector 2. Trapezoidal blocks 12 are symmetrically arranged on both sides of the conical block 11. When the adjusting screw 8 is rotated, its threaded connection with the connector 2 causes the conical block 11 to move up and down in the drive cavity 7. By utilizing the tangential engagement between the inclined surfaces on both sides of the conical block 11 and the inclined surfaces on the inner sides of the trapezoidal blocks 12, the rotational motion of the adjusting screw 8 is converted into the horizontal movement of the trapezoidal blocks 12.

[0028] Slider 13 is fixedly installed on the inclined surfaces of both trapezoidal blocks 12. Slide rails 14 are provided on both inclined surfaces of the conical block 11. The conical block 11 is slidably installed inside the slide rails 14 on the inner side of the two trapezoidal blocks 12 via the slider 13. The slider 13 fixed on the inclined surface of the trapezoidal block 12 and the slide rail 14 on the inclined surface of the conical block 11 form a sliding fit. When the adjusting screw 8 is rotated to drive the conical block 11 to move up and down along the slide rail 14, the slider 13 slides synchronously in the slide rail 14. Through the guiding and limiting effect of the slide rail 14 on the slider 13, the trapezoidal block 12 can only move horizontally along the slide groove 16 of the connecting piece 2, avoiding skewing or radial displacement under the thrust of the inclined surface of the conical block 11. L-shaped limiting plates 15 are fixedly installed on both sides of the two trapezoidal blocks 12. U-shaped slots 17 are provided on the inner side of the two L-shaped limiting plates 15.

[0029] Please see Figures 2-7 The arc surface inside the U-shaped slot 17 is adapted to the size of the fastening screw 5. When the conical block 11 pushes the trapezoidal block 12 through the inclined surface to move the L-shaped limiting plate 15, the arc surface of the U-shaped slot 17 can closely fit the outer surface of the fastening screw 5 to form a ring-shaped limiting structure. This can evenly distribute the clamping force on the fastening screw 5 and avoid stress concentration due to rigid contact. At the same time, the friction is increased through curved surface contact to ensure that the fastening screw 5 will not loosen when subjected to vibration or load. The connection between the surface of the adjusting screw 8 and the upper end of the connector 2 is a threaded connection. The two I-shaped steels 1 are symmetrically provided with mounting holes 4 on both sides of the connection. The fastening screw 5 passes through the mounting hole 4 and is threadedly connected to the nut 6. By rotating the adjusting screw 8, the rotational motion can be converted into the up and down linear motion of the conical block 11. The self-locking characteristic of the threaded transmission is used to keep the adjusted position stable and ensure that the clamping force generated by the conical block 11 pushing the trapezoidal block 12 is continuously effective.

[0030] A handle 9 is fixedly installed on the top of the adjusting screw 8. A fastening hole 10 is opened on the top of the handle 9. Slots 3 are symmetrically opened on both sides of the connector 2. The slots 3 are adapted to the end face of the I-shaped steel 1. The I-shaped steel 1 is inserted into the connector 2 through the slots 3. When the I-shaped steel 1 is inserted into the connector 2, the middle part of the fastening screw 5 corresponds to the U-shaped groove 17. When the adjusting screw 8 is rotated, the threaded connection causes the adjusting screw 8 to drive the conical block 11 to move upward along the slide rail 14. Due to the bottom of the conical block 11 The inclined surface is tangent to the inner inclined surface of the trapezoidal block 12. When the conical block 11 moves upward, the two trapezoidal blocks 12 move closer to each other along the slide groove 16 through the cooperation of the slide rail 14 and the slide groove 16, thereby driving the L-shaped limiting plates 15 on both sides to move synchronously, so that the U-shaped slot 17 forms a ring-shaped limiting on the middle of the fastening screw 5, realizing the quick fastening connection between the I-shaped steel 1 and the connecting piece 2, avoiding the disadvantage of traditional welding that requires cutting and damage. When disassembling, the limiting can be released by rotating the adjusting screw 8 in the opposite direction to separate the trapezoidal block 12. The operation is convenient and efficient.

[0031] Two symmetrical grooves 16 are provided on both sides of the connector 2. The L-shaped limiting plates 15 on both sides of the trapezoidal block 12 are slidably installed inside the grooves 16. When the conical block 11 pushes the trapezoidal block 12 to move through the inclined surface, the L-shaped limiting plates 15 slide synchronously along the grooves 16. The limiting function of the grooves 16 ensures that the L-shaped limiting plates 15 can only move horizontally, preventing them from deflecting or deviating from the predetermined trajectory during movement. The inclined surface at the bottom of the conical block 11 is tangent to the inner inclined surface of the trapezoidal block 12. When the conical block 11 moves upward along the slide rail 14, the two trapezoidal blocks move closer to each other, and at the same time, the fastening screw 5 is connected to the U-shaped slot 17. This allows the U-shaped slot 17 to accurately align with the fastening screw 5 and achieve uniform clamping, improving the stability and reliability of the connecting component during operation and ensuring the precise execution of fastening and disassembly actions.

[0032] Working principle: In actual use, first, pass the fastening screw 5 through the mounting hole 4 and tighten the nut 6 to complete the initial fixation. Then, insert the end faces of the two I-shaped steels 1 into the slots 3 on both sides of the connector 2 respectively, so that the I-shaped steels 1 and the connector 2 are positioned. At this time, the position of the fixing screw corresponds to the position of the U-shaped slot 17 opened on the inner side of the L-shaped limiting plate 15.

[0033] Next, rotate the handle 9 at the top of the adjusting screw 8. Since the adjusting screw 8 is threadedly connected to the upper end of the connecting piece 2, when rotating, the adjusting screw 8 drives the conical block 11 to move upward along the slide rail 14. Since the bottom inclined surface of the conical block 11 is tangent to the inner inclined surface of the trapezoidal block 12, during the upward movement of the conical block 11, the inclined surface pulls the two trapezoidal blocks 12 closer to each other along the slide groove 16 of the connecting piece 2. The trapezoidal blocks 12 drive the two L-shaped limiting plates 15 to move synchronously, so that the U-shaped slot 17 on the inner side of the L-shaped limiting plate 15 gradually moves closer to the middle of the fastening screw 5.

[0034] When the U-shaped slot 17 moves to the position corresponding to the middle of the fastening screw 5, the arc surface of the U-shaped slot 17 fits tightly with the fastening screw 5 to form a ring-shaped limit. At this time, the conical block 11 slides stably in the slide rail 14 of the trapezoidal block 12 through the slider 13 to ensure the synchronous movement of the trapezoidal blocks 12 on both sides.

[0035] During disassembly, the adjusting screw 8 is rotated in the opposite direction, the conical block 11 moves downward along the slide rail 14, and the trapezoidal block 12 separates from each other along the slide groove 16 under the pressure of the inclined surface of the conical block 11. The L-shaped limiting plate 15 drives the U-shaped slot 17 to release the limiting of the fastening screw 5, and then the I-shaped steel 1 can be separated from the connecting piece 2.
