Description
Technical Field
[0001] This utility model belongs to the field of steel structure installation technology, and in particular relates to a quick-installation steel structure connection component. Background Technology
[0002] Steel structures refer to building or engineering structural systems composed of steel components such as steel profiles, steel plates, and steel pipes, assembled through welding, bolting, or riveting. They have advantages such as high strength, light weight, good toughness, fast construction speed, and the ability to be disassembled and reused. They are widely used in various industrial and civil building fields such as factories, bridges, high-rise buildings, stadiums, warehouses, towers, and temporary structures. Their design is based on mechanical performance and structural stability requirements, and they can withstand various external forces such as self-weight, wind load, seismic force, and temperature stress.
[0003] Existing steel structure installations require a quick-installation connection component suitable for temporary or modular steel structure projects that require frequent installation and disassembly. The problems with existing technologies are: Current steel structure installations typically rely on traditional methods such as welding, bolting, or riveting to fix and connect components. These methods generally suffer from long construction cycles, complex operations, high skill requirements for construction workers, and inconvenient disassembly. Especially in temporary or modular projects requiring frequent assembly and disassembly, traditional connection methods struggle to meet the practical needs for efficiency, convenience, and reusability. Utility Model Content
[0004] In view of the problems existing in the prior art, this utility model provides a quick-installation steel structure connection component that can overcome or at least partially solve the above problems.
[0005] This utility model is implemented as follows: a quick-installation steel structure connection component includes a steel frame, a positioning frame, and a mounting plate. The two ends of the steel frame are in contact with the surfaces of the two positioning frames. The two ends of the positioning frames are fixedly connected to the lower ends of the two mounting plates by bolts. A connection mechanism is provided inside the positioning frame, and an auxiliary mechanism is provided at one end of the connection mechanism. The connecting mechanism is used for fixed connection of the steel frame; The auxiliary mechanism is used to fix the connecting mechanism.
[0006] To improve the synchronization of the installation process, preferably, the connecting mechanism includes a fixed plate, a positioning plate, a double-ended screw, a connecting plate, and a limiting plate. The inner wall of the fixed plate is fixedly connected to the surface of the positioning plate, and the inner wall of the positioning plate is rotatably connected to the middle surface of the double-ended screw. The two ends of the double-ended screw are threadedly connected to the inner wall of the connecting plate, and the lower end of the connecting plate is fixedly connected to the surface of the limiting plate. The two ends of the double-ended screw are respectively provided with threads in opposite directions, forming a threaded engagement with the inner wall of the connecting plate. This allows the two connecting plates to move synchronously in opposite directions when the double-ended screw rotates, thereby achieving a symmetrical force application effect and effectively avoiding skewing or jamming caused by uneven force.
[0007] To improve operational safety, the auxiliary mechanism preferably includes a stop plate, a bearing plate, an elastic block, a support plate, and a guide rod. The surface of the stop plate is slidably connected to the inner wall of the bearing plate via a groove. The upper surface of the bearing plate is fixedly connected to the lower surface of the elastic block, and the upper surface of the elastic block is fixedly connected to the lower surface of the support plate. The inner wall of the support plate is slidably connected to the surface of the guide rod. The elastic block can provide a restoring force when the support plate is pulled or released by an external force, so that the stop plate automatically resets and remains embedded in the fixed groove when no external force is applied, thereby realizing the self-locking function of the double-ended screw position and preventing loosening caused by vibration or other external loads.
[0008] To improve stability during use, preferably, the positioning frame has a fixing groove on the right end and the steel frame has mating grooves at both ends. By setting the fixing groove on the right end of the positioning frame and making it detachably plugged into the stop plate, an auxiliary locking function can be provided for the double-headed screw assembly while the limiting plate is inserted into the mating groove of the steel frame, preventing the screw from rotating due to external vibration or load changes.
[0009] To improve operational efficiency, preferably, the surface of the fixing plate is fixedly connected to the inner wall of the positioning frame, the surface of the connecting plate is slidably connected to the inner wall of the positioning frame, the surface of the limiting plate is in contact with the inner wall of the mating groove, the two ends of the double-headed screw are rotatably connected to the inner walls of the two sides of the positioning frame, and the surface of the limiting plate is in contact with the inner wall of the mating groove opened on the steel frame. Through the tight fit between the limiting plate and the mating groove, a stable mechanical fitting state is formed, which not only improves the shear resistance between the connecting components and the steel frame, but also enhances the structural stability of the connecting node under complex working conditions. At the same time, it facilitates on-site construction personnel to quickly complete the locking or releasing operation of the steel structure.
[0010] To improve construction efficiency, preferably, the surface of the stop plate is in contact with the inner wall of the fixing groove, the inner wall of the bearing plate is fixedly connected to the surface of the guide rod, and the upper end of the stop plate is fixedly connected to the inner wall of the support plate. A stable structural support relationship is formed between the bearing plate and the guide rod, and the bearing plate will not shift or shake during the force process, thereby providing a stable foundation support for the sliding action of the stop plate.
[0011] To improve on-site assembly efficiency, preferably, the right end of the double-headed screw is fixedly connected to the left end of the guide rod, and the lower surface of the positioning plate is in contact with the inner wall of the steel frame. Through the fit between the positioning plate and the inner wall of the steel frame, the relative position between the positioning frame and the steel frame is initially defined, which can provide a certain support for the overall structure before the connecting components are fully locked, and prevent installation errors caused by misalignment or shaking.
[0012] This utility model incorporates a connecting mechanism, an auxiliary mechanism, a positioning plate, a double-ended screw, a connecting plate, a limiting plate, a stop plate, a bearing plate, an elastic block, a support plate, and a guide rod. The connecting mechanism is used to fix the steel frame, and the auxiliary mechanism is used to fix the connecting mechanism. The double-ended screw has threads with opposite directions at both ends, forming a threaded engagement with the inner wall of the connecting plate. This allows the two connecting plates to move synchronously in opposite directions when the double-ended screw rotates, achieving symmetrical force application and effectively avoiding skewing or jamming caused by uneven force. The elastic block provides restoring force when the support plate is pulled or released by external force, allowing the stop plate to automatically reset and remain embedded in the fixing groove without external force, thus achieving a self-locking function for the position of the double-ended screw and preventing loosening caused by vibration or other external loads. This solves the problem that in the prior art, steel structures usually rely on traditional welding, bolting, or riveting methods for fixing and splicing components during installation. These methods generally suffer from long construction cycles, complex operations, high technical requirements for construction personnel, and inconvenient disassembly. Especially in temporary or modular projects that require frequent assembly and disassembly, traditional connection methods are unable to meet the actual needs of efficiency, convenience and reusability.

Detailed Implementation
[0015] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0016] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0017] like Figures 1 to 4As shown in the figure, this utility model provides a quick-installation steel structure connection assembly, including a steel frame 5, positioning frames 6, and mounting plates 7. Both ends of the steel frame 5 are in contact with the surfaces of two positioning frames 6. Both ends of the positioning frames 6 are fixedly connected to the lower ends of two mounting plates 7 by bolts. A connecting mechanism 1 is provided inside the positioning frames 6, and an auxiliary mechanism 2 is provided at one end of the connecting mechanism 1. The connecting mechanism 1 is used to fix the steel frame 5, and the auxiliary mechanism 2 is used to fix the connecting mechanism 1. The connecting mechanism 1 includes a fixing plate 101, a positioning plate 102, a double-ended screw 103, a connecting plate 104, and a limiting plate 105. The inner wall of the fixing plate 101 is fixedly connected to the surface of the positioning plate 102, and the inner wall of the positioning plate 102 is rotatably connected to the middle surface of the double-ended screw 103. Both ends of the screw 103 are threadedly connected to the inner wall of the connecting plate 104. The lower end of the connecting plate 104 is fixedly connected to the surface of the limiting plate 105. The two ends of the double-ended screw 103 are respectively provided with threads in opposite directions, which form a threaded engagement with the inner wall of the connecting plate 104. This allows the two connecting plates 104 to move synchronously in opposite directions when the double-ended screw 103 rotates, thereby achieving the effect of symmetrical force application and effectively avoiding the phenomenon of skewing or jamming caused by uneven force. The auxiliary mechanism 2 includes a stop plate 201, a bearing plate 202, an elastic block 203, a support plate 204, and a guide rod 205. The surface of the stop plate 201 is slidably connected to the inner wall of the bearing plate 202 through a sliding groove. The upper surface of the bearing plate 202 is fixedly connected to the lower surface of the elastic block 203. The upper surface is fixedly connected to the lower surface of the support plate 204, and the inner wall of the support plate 204 is slidably connected to the surface of the guide rod 205. The elastic block 203 can provide a restoring force when the support plate 204 is pulled or released by an external force, so that the stop plate 201 automatically resets and remains embedded in the fixing groove 3 without external force, thereby realizing the self-locking function of the position of the double-ended screw 103 and preventing loosening caused by vibration or other external loads. The right end of the positioning frame 6 is provided with a fixing groove 3, and both ends of the steel frame 5 are provided with mating grooves 4. By setting the fixing groove 3 at the right end of the positioning frame 6 and making it detachably plugged into the stop plate 201, it can provide an auxiliary locking function for the double-ended screw 103 assembly while the limiting plate 105 is inserted into the mating groove 4 of the steel frame 5, preventing... To prevent screw rotation caused by external vibration or load changes, the surface of the fixing plate 101 is fixedly connected to the inner wall of the positioning frame 6, the surface of the connecting plate 104 is slidably connected to the inner wall of the positioning frame 6, the surface of the limiting plate 105 contacts the inner wall of the mating groove 4, and the two ends of the double-ended screw 103 are rotatably connected to the inner walls of both sides of the positioning frame 6. The surface of the limiting plate 105 contacts the inner wall of the mating groove 4 opened on the steel frame 5. Through the tight fit between the limiting plate 105 and the mating groove 4, a stable mechanical fitting state is formed, which not only improves the shear resistance between the connecting components and the steel frame 5, but also enhances the structural stability of the connection node under complex working conditions. At the same time, it facilitates the quick locking or releasing operation of the steel structure by on-site construction personnel. The surface of the stop plate 201 contacts the inner wall of the fixing groove 3.The inner wall of the bearing plate 202 is fixedly connected to the surface of the guide rod 205, and the upper end of the stop plate 201 is fixedly connected to the inner wall of the support plate 204. A stable structural support relationship is formed between the bearing plate 202 and the guide rod 205. The bearing plate 202 will not shift or shake during the stress process, thus providing a stable foundation support for the sliding action of the stop plate 201. The right end of the double-ended screw 103 is fixedly connected to the left end of the guide rod 205. The lower surface of the positioning plate 102 contacts the inner wall of the steel frame 5. Through the fit between the positioning plate 102 and the inner wall of the steel frame 5, the relative position between the positioning frame 6 and the steel frame 5 is initially defined. This provides a certain degree of support for the overall structure before the connecting components are fully locked, preventing installation errors caused by misalignment or shaking.
[0018] During the rapid connection and installation of the steel structure, the mounting plate 7 is first firmly fixed to the specific position of the steel structure to be connected. Then, the inner wall of the steel frame 5 to be connected is brought into contact with the surface of the positioning plate 102 on the mounting plate 7, ensuring that the positioning plate 102 inside the positioning frame 6 is tightly fitted to the inner wall of the steel frame 5. This achieves initial positioning of the positioning frame 6, ensuring its stability relative to the steel frame 5. After initial positioning, the double-ended screw 103 located at the right end of the positioning frame 6 is rotated. Since the two ends of the double-ended screw 103 have threads with opposite directions of rotation, when the screw is rotated, the two connecting plates 104 connected to its surface will drive the limiting plate 105 to move synchronously towards the steel frame 5 along the inner wall of the positioning frame 6. As the screw continues to rotate, the limiting plate 105 gradually approaches the surface of the steel frame 5 until it is fully inserted into the pre-drilled mating grooves 4 on both sides of the steel frame 5 and in close contact with its surface, thus achieving a stable connection between the steel structure and the steel frame 5. To further enhance the connection... For reliability, after the limiting plate 105 is inserted, the support plate 204 on the guide rod 205 at the right end of the double-ended screw 103 is pulled, causing the stop plate 201 inside the support plate 204 to slide into the fixing groove 3 on the right side of the positioning frame 6 along the guide direction of the bearing plate 202. At this time, the elastic block 203 set between the bearing plate 202 and the support plate 204 during the installation process will use its own elastic force to make the stop plate 201 stably embedded in the fixing groove 3, thereby locking the position of the double-ended screw 103 and preventing it from loosening due to vibration or other external forces during use, thus effectively ensuring the stability and safety of the entire connection structure. When it is necessary to disassemble the steel structure, the operation process is the reverse of the above steps. First, the support plate 204 is pulled to make the stop plate 201 come out of the fixing groove 3; then the double-ended screw 103 is rotated in the opposite direction to drive the limiting plate 105 to be pulled out from the mating groove 4 of the steel frame 5, thereby releasing the connection between the two and realizing the rapid separation and disassembly of the steel structure.
[0019] The specific models and specifications of the steel frame 5, double-ended screw 103, and elastic block 203 proposed in this application need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.
