Description

Technical Field

[0001] This utility model relates to the field of steel structure platform technology, specifically a main beam connection structure for a steel platform. Background Technology

[0002] Steel structure platforms, also known as work platforms, come in various structural forms and offer a full range of functions. Their most prominent feature is their fully assembled structure, allowing for flexible design and widespread application in modern storage. These steel structures are typically composed of beams, columns, and plates made of shaped steel and steel plates; the various parts are connected by welds, screws, or rivets.

[0003] Chinese utility model patent CN208918219U discloses an automated steel platform main beam connection structure, including a steel platform main beam. One end of the steel platform main beam is provided with three fixed connection holes. One side of the fixed connection holes is provided with four fixed assembly holes. Both sides of the fixed assembly holes are provided with long grooves. A U-shaped metal plate is installed on one side of the steel platform main beam, and the U-shaped metal plate is located inside the long groove. The bottom surface of the inner wall of the U-shaped metal plate is provided with four high-precision connector assembly holes. A square shock-absorbing rubber plate is installed on one end face of the U-shaped metal plate.

[0004] However, the connection holes on the high-precision metal connecting plate of the main beam connection structure of the automated steel platform of this utility model are fixed in position and need to be completely aligned with the fixed connection holes of another main beam in order to be fixed with bolts. However, errors will occur during actual processing and installation, resulting in misalignment between the fixed connection holes and the connection holes, making it impossible to smoothly insert bolts. This not only reduces installation efficiency, but may also generate additional stress due to forced docking, affecting the structural stability. Therefore, a steel platform main beam connection structure is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a steel platform main beam connection structure, which has advantages such as high connection efficiency and solves the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A steel platform main beam connection structure includes a steel platform main beam body, an U-shaped metal plate disposed inside the steel platform main beam body, and a high-precision metal connecting plate fixedly connected to the outside of the U-shaped metal plate. The high-precision metal connecting plate is provided with a connecting component that can flexibly adjust its position, and the connecting component is provided with a limiting structure for limiting its position.

[0008] The connecting assembly includes a movable plate that is slidably connected to the outside of the high-precision metal connecting plate. The movable plate has a plurality of connecting holes inside, and a slider that extends into the interior of the high-precision metal connecting plate is fixedly connected to the back of the movable plate.

[0009] The limiting structure includes a fixed base fixedly connected to the outside of a high-precision metal connecting plate. A threaded rod is rotatably connected inside the fixed base. A movable block is threadedly connected to the outside of the threaded rod. An insert rod extending into the inside of the movable plate is fixedly connected to one side of the movable block.

[0010] Furthermore, the plurality of connecting holes are distributed at equal intervals inside the movable plate, and the movable plate is slidably connected to the outside of the high-precision metal connecting plate.

[0011] Furthermore, the high-precision metal connecting plate has a sliding groove inside that matches the slider, and the slider and the sliding groove are slidably connected.

[0012] Furthermore, a limiting hole adapted to the insertion rod is provided on one side of the outer side of the movable plate. The insertion rod and the limiting hole are inserted into each other, and there are multiple limiting holes.

[0013] Furthermore, a knob is fixedly connected to the end of the threaded rod away from the fixed seat, and anti-slip rubber is fixedly connected to the outside of the knob.

[0014] Furthermore, the fixed base has a moving opening inside that matches the moving block, and a limiting block extending into the fixed base is fixedly connected to the bottom of the moving block.

[0017] Compared with the prior art, this utility model provides a steel platform main beam connection structure, which has the following advantages:

[0018] 1. The main beam connection structure of this steel platform uses a sliding assembly where the slider on the back of the moving plate slides into the groove inside the high-precision metal connecting plate. Combined with multiple equally spaced connecting holes on the moving plate, the relative position of the connecting holes and the fixed connecting holes of the main beam of the steel platform can be flexibly adjusted, effectively offsetting processing errors and installation deviations, solving the problem of docking difficulties caused by hole misalignment, and significantly improving installation adaptability.

[0019] 2. The main beam connection structure of this steel platform uses a knob to rotate a threaded rod, causing the moving block to move within the fixed seat. This pushes the insert rod into the limiting hole of the moving plate, and with the help of the spring force, it can stably limit the adjusted moving plate. Furthermore, the C-shaped metal plate slides into the long groove and is fixed by bolts through high-precision connecting parts assembly holes.

[0024] 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.

[0025] Please see Figures 1 to 3The steel platform main beam connection structure in this embodiment includes a steel platform main beam body 1, an inverted metal plate 4 disposed inside the steel platform main beam body 1, and a high-precision metal connecting plate 5 fixedly connected to the outside of the inverted metal plate 4. The high-precision metal connecting plate 5 is provided with a connecting component 7 for flexible position adjustment, and the connecting component 7 is provided with a limiting structure 8 for limiting position.

[0026] The connecting component 7 includes a movable plate 71 that is slidably connected to the outside of the high-precision metal connecting plate 5. The movable plate 71 has a plurality of connecting holes 72 inside, and a slider 73 that extends into the interior of the high-precision metal connecting plate 5 is fixedly connected to the back of the movable plate 71.

[0027] Specifically, multiple connecting holes 72 are arranged at equal intervals inside the movable plate 71, which is slidably connected to the outside of the high-precision metal connecting plate 5. Through the sliding of the movable plate 71 and the arrangement of the multiple equally spaced connecting holes 72, the mating position of the connecting holes 72 can be flexibly adjusted according to the actual position of the fixed connecting holes 2 on the main body 1 of the steel platform beam. This effectively offsets processing errors and installation deviations, avoids the problem of bolts not being able to be inserted due to misaligned holes, and improves the efficiency and success rate of the main beam connection.

[0028] It should be noted that the high-precision metal connecting plate 5 has a sliding groove 74 that matches the slider 73 inside, and the slider 73 and the sliding groove 74 are slidably connected.

[0029] It is worth mentioning that a limiting hole 75 adapted to the insertion rod 85 is provided on one side of the movable plate 71. The insertion rod 85 and the limiting hole 75 are inserted into each other, and there are multiple limiting holes 75.

[0030] In this embodiment, the limiting structure 8 includes a fixed seat 81 fixedly connected to the outside of the high-precision metal connecting plate 5. A threaded rod 82 is rotatably connected inside the fixed seat 81. A moving block 84 is threadedly connected to the outside of the threaded rod 82. An insert rod 85 extending into the inside of the moving plate 71 is fixedly connected to one side of the moving block 84.

[0031] Among them, the end of the threaded rod 82 away from the fixed seat 81 is fixedly connected to a knob 83, and the knob 83 is fixedly connected to an anti-slip rubber.

[0032] Specifically, the fixed base 81 has a movable opening inside that matches the movable block 84. A limiting block extending into the fixed base 81 is fixedly connected to the bottom of the movable block 84. The fixed base 81 has a limiting groove inside that matches the limiting block, and the limiting block and the limiting groove are slidably connected. By rotating the knob 83, the threaded rod 82 rotates, causing the movable block 84 to move, thereby allowing the insertion rod 85 to insert into the corresponding limiting hole 75 on the movable plate 71. Combined with the slidable connection of the limiting block and the limiting groove, and the action of the abutment spring 86, the adjusted movable plate 71 can be securely fixed to the high-precision metal connecting plate 5, preventing slippage after connection. This ensures the stability and reliability of the connection structure and enhances the overall load-bearing capacity and safety of the steel platform.

[0033] It should be noted that a retaining spring 86 is fixedly connected between the moving block 84 and the fixed seat 81, and the retaining spring 86 is connected to the outside of the threaded rod 82.

[0034] In this embodiment, the main body 1 of the steel platform has a fixed connection hole 2 that matches the connection hole 72 inside. The main body 1 also has a long groove 3 inside, and a U-shaped metal plate 4 is slidably connected inside the long groove 3. The main body 1 also has an installation hole that matches the U-shaped metal plate 4 inside. The U-shaped metal plate 4 has a high-precision connector assembly hole 6 inside, and the high-precision connector assembly hole 6 and the installation hole are fixed with bolts. By fixing the U-shaped metal plate 4 with bolts through the high-precision connector assembly hole 6 and the installation hole, the stability of the U-shaped metal plate 4 installation is ensured, and a reliable installation foundation is provided for the high-precision metal connecting plate 5 and subsequent connecting components 7 and limiting structures 8. This allows the entire connection structure to be tightly integrated with the main body 1 of the steel platform, improving the quality and effectiveness of the connection.

[0035] The working principle of the above embodiments is as follows:

[0036] First, the C-shaped metal plate 4 is slidably inserted into the long groove 3 of the main body 1 of the steel platform beam, aligning the high-precision connector assembly hole 6 of the C-shaped metal plate 4 with the mounting hole of the main body 1 of the steel platform beam. The two are then fixed with bolts, forming a stable connection between the C-shaped metal plate 4 and the main body 1 of the steel platform beam. Next, the high-precision metal connecting plate 5 is used to extend the connection to other main bodies 1 of the steel platform beam: the moving plate 71 of the connecting component 7 is pushed, causing the slider 73 on its back to slide along the groove 74 of the high-precision metal connecting plate 5, adjusting the movement... The connecting hole 72 on plate 71 is aligned with the fixed connecting hole 2 of the main body 1 of the steel platform to be connected; after alignment, the knob 83 of the limiting structure 8 is rotated, which drives the threaded rod 82 to rotate, so that the moving block 84 moves in the moving port of the fixed seat 81, pushing the insertion rod 85 into the corresponding limiting hole 75 of the moving plate 71. At the same time, the spring 86 is compressed and generates elastic force to enhance the insertion and fastening, thus completing the limiting and fixing of the moving plate 71; finally, the bolts pass through the fixed connecting hole 2 and the connecting hole 72 to achieve a precise and stable connection of the two main bodies 1 of the steel platform.
