Description

Technical Field

[0001] This application belongs to the field of steel structure platform technology, specifically a steel structure platform that can be quickly disassembled. Background Technology

[0002] A steel structure platform is a horizontal support structure built primarily of steel (such as I-beams, channel steel, and H-beams). It forms a frame system through steel columns, steel beams, and other components. It features high strength, light weight, fast construction speed, large span, and flexible design. It can meet the load-bearing and usage requirements of various building scenarios such as industrial plants, warehouses, shopping malls, and stadiums. It is commonly used for equipment installation, cargo storage, and personnel operation platforms. It can adapt to different load requirements and has good seismic and wind resistance. The structure can be flexibly designed and arranged according to functional requirements.

[0003] For example, the utility model patent with announcement number CN220058732U discloses a steel structure platform, including a first platform panel and a second platform panel. One end of the first platform panel is snapped into one end of the second platform panel. Both the first and second platform panels are provided with support legs at their bottoms. This utility model facilitates the fixed installation of the horizontal plate and the first platform panel by setting up a second spring, a fixing column, a fixing groove, a connecting column, a first spring, and a placement groove. Finally, the second platform panel is fixedly installed to the first platform panel. Compared with the connection using welds, bolts, or rivets, this method is more convenient and faster, and the installation process is time-saving and labor-saving. By setting up pull rings, a first connecting line, and a second connecting line, it is easy to remove the fixing column from the fixing groove and the connecting column from the placement groove, thereby separating the first platform panel from the horizontal plate.

[0004] However, during actual use, it was found that the elastic properties of the first and second springs of the device are easily degraded due to long-term compression, resulting in a decrease in the fixing effect and posing a safety hazard. Furthermore, components such as springs and connecting wires are hidden in the internal structure of the fixing cylinder and connecting column, making it difficult to detect when a fault occurs. Repair requires disassembling multiple external components, resulting in high maintenance costs and time consumption. In addition, the snap-fit ​​structure is prone to damage to components during disassembly, affecting the reusability. Therefore, a steel structure platform that can be quickly disassembled is provided. Utility Model Content

[0005] The purpose of this application is to provide a steel structure platform that can be quickly disassembled in order to solve the problems mentioned above.

[0006] The technical solution adopted in this application is as follows: a quick-disassembly steel structure platform, including a bottom support steel column, a platform steel beam provided on the top surface of the bottom support steel column, and a connection and fixing mechanism connected to the platform steel beam provided on the top surface of the bottom support steel column.

[0007] The connecting and fixing mechanism includes a convex plate, an L-shaped limiting plate, a bearing, a screw, a mounting plate, limiting and fixing columns, and a rotating head. The convex plate is fixedly installed on the side of the platform steel beam. The top surface of the bottom supporting steel column is fixedly installed with an L-shaped limiting plate by bolts. A bearing is fixedly installed on one side of the L-shaped limiting plate. A screw is rotatably connected to the middle of the bearing. The outer surface of the screw is threadedly connected to the mounting plate. Multiple limiting and fixing columns are fixedly installed on one side of the mounting plate, and one end of each limiting and fixing column penetrates one side of the L-shaped limiting plate. The outer surface of the limiting and fixing column away from the mounting plate is close to the side of the convex plate. The rotating head is fixedly installed on the end of the screw away from the bearing.

[0008] In a preferred embodiment, reinforcing plates are respectively provided on the left and right sides of the bottom supporting steel column below the platform steel beam. A positioning connection mechanism connected to the reinforcing plates is provided on the side of the bottom supporting steel column. The top surface of the reinforcing plates is in contact with the bottom surface of the platform steel beam. Triangular brackets are fixedly installed on the left and right sides of the bottom supporting steel column below the reinforcing plates by bolts. A U-shaped limiting plate is fixedly installed on the top surface of the triangular brackets. The bottom surface of the reinforcing plates is inserted into the U-shaped limiting plate.

[0009] In a preferred embodiment, the positioning and connecting mechanism includes a T-shaped limiting groove and a T-shaped limiting block. T-shaped limiting grooves are respectively opened on the left and right sides of the bottom supporting steel column. T-shaped limiting blocks corresponding to the T-shaped limiting grooves are respectively fixedly installed on the left and right ends of the reinforcing support plate. The T-shaped limiting blocks are inserted into the inside of the T-shaped limiting grooves.

[0010] In a preferred embodiment, a platform steel deck is fixedly installed on the top surface of the platform steel beam, and a guardrail is fixedly installed on the top surface of the platform steel deck.

[0011] In a preferred embodiment, a bottom fixing plate is fixedly installed at the bottom end of the bottom supporting steel column, and a plurality of mounting through holes are provided on the top surface of the bottom fixing plate near the corner.

[0012] In a preferred embodiment, a steel structure ladder is provided on the side of the platform steel beam, and a guardrail is fixedly installed on the top surface of the steel structure ladder.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0014] 1. In this application, due to the adoption of the above-mentioned scheme, the device can achieve positioning of the side of the platform steel beam using the L-shaped limiting plate. Then, the operator first rotates the rotating head to drive the screw to rotate. The screw drives the mounting plate to move, so that the convex plate is inserted between the two sets of limiting and fixing columns. In this way, the platform steel beam and the bottom support steel column can be quickly fixed. During disassembly, the above steps are reversed. The connecting and fixing mechanism is loosened in sequence, and the reinforcing plate and other components are removed to quickly complete the platform disassembly. The device facilitates the quick connection and fixing between the bottom support steel column and the platform steel beam through the connecting and fixing mechanism. The installation of the reinforcing plate can further improve the stability of the steel structure platform. The whole process is simple to operate and can effectively improve the disassembly and assembly efficiency and the flexibility of use of the steel structure platform. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] refer to Figures 1-4As shown, a quick-disassembly steel structure platform includes a bottom support steel column 1. A bottom fixing plate 10 is fixedly installed at the bottom end of the bottom support steel column 1. Multiple mounting through holes are opened on the top surface of the bottom fixing plate 10 near the corners. Through the bottom fixing plate 10, personnel can pass bolts through the mounting through holes, so that the bolts can be easily and firmly connected to the threaded holes opened on the ground or foundation structure, which greatly enhances the overall stability of the steel structure platform and prevents the platform from shifting or tilting during use.

[0022] refer to Figures 1-4 As shown, a platform steel beam 2 is installed on the top surface of the bottom supporting steel column 1, and a steel structure ladder 11 is installed on the side of the platform steel beam 2. A guardrail is fixedly installed on the top surface of the steel structure ladder 11, and a platform steel deck 8 is fixedly installed on the top surface of the platform steel beam 2. A guardrail 9 is fixedly installed on the top surface of the platform steel deck 8. A connecting and fixing mechanism 3 connected to the platform steel beam 2 is installed on the top surface of the bottom supporting steel column 1. The platform steel beam 2 provides stable support for the platform steel deck 8, forming a working plane for carrying goods and personnel, meeting diverse usage needs. The steel structure ladder 11 and guardrail provide a safe passage for personnel to go up and down the platform, effectively ensuring the personal safety of operators. The guardrail 9 prevents personnel or objects from falling from the edge of the platform, further improving the safety of platform use. The connecting and fixing mechanism 3 facilitates quick assembly and disassembly of the connection between the platform steel beam 2 and the bottom supporting steel column 1, significantly improving installation and disassembly efficiency.

[0023] refer to Figures 1-4 As shown, the connecting and fixing mechanism 3 includes a convex plate 301, an L-shaped limiting plate 302, a bearing 303, a screw 304, a mounting plate 305, a limiting and fixing column 306, and a rotating head 307. The convex plate 301 is fixedly installed on the side of the platform steel beam 2, and the L-shaped limiting plate 302 is fixedly installed on the top surface of the bottom supporting steel column 1 by bolts. The bearing 303 is fixedly installed on one side of the L-shaped limiting plate 302, and the screw 304 is rotatably connected to the middle of the bearing 303. The L-shaped limiting plate 302 facilitates the initial positioning of the platform steel beam 2, ensuring the accuracy of installation. The bearing 303 makes the screw 304 rotate more smoothly and flexibly. The operator can easily drive the screw 304 by rotating the head 307, which can reduce the difficulty of operation and labor intensity. At the same time, the bolt-mounted L-shaped limiting plate 302 is easy to disassemble and reuse, reducing maintenance costs.

[0024] refer to Figures 1-4As shown, a mounting plate 305 is threaded onto the outer surface of the screw 304. Multiple limiting posts 306 are fixedly mounted on one side of the mounting plate 305, with one end of each limiting post 306 penetrating one side of the L-shaped limiting plate 302. The outer surface of the end of the limiting post 306 away from the mounting plate 305 is close to the side of the protruding plate 301. A rotating head 307 is fixedly mounted on the end of the screw 304 away from the bearing 303. There are four limiting posts 306 in total, arranged in two groups of two. The screw 304 is rotated by rotating the rotating head 307. This causes the mounting plate 305 to move axially along the screw 304, thereby pushing the limiting and fixing column 306 forward. This allows the protruding plate 301 to be inserted between multiple limiting and fixing columns 306. The protruding plate 301 can be an I-beam protrusion. If an I-beam is not used, the protruding plate can be installed separately by welding to facilitate subsequent limiting and fixing of the platform. This facilitates the rapid fixing of the platform steel beam 2 and the bottom support steel column 1. The operation is simple and quick, ensuring the stability of the platform structure. This connection method does not require complicated tools, and disassembly can be done by simply rotating in the opposite direction, effectively shortening the platform assembly and disassembly time and improving construction efficiency.

[0025] refer to Figures 1-4 As shown, reinforcing support plates 4 are respectively installed on the left and right sides of the bottom supporting steel column 1 below the platform steel beam 2. Positioning connection mechanisms 7 connected to the reinforcing support plates 4 are installed on the sides of the bottom supporting steel column 1. The positioning connection mechanism 7 includes a T-shaped limiting groove 701 and a T-shaped limiting block 702. T-shaped limiting grooves 701 are respectively opened on the left and right sides of the bottom supporting steel column 1. T-shaped limiting blocks 702 corresponding to the T-shaped limiting grooves 701 are fixedly installed at the left and right ends of the reinforcing support plate 4. The T-shaped limiting blocks 702 are inserted into the T-shaped limiting grooves 701. The T-shaped limiting groove 701 is internal; the reinforced support plate 4 increases the connection points between the platform steel beam 2 and the bottom support steel column 1, effectively dispersing the load borne by the platform and improving the overall structural strength and stability of the platform. The cooperation between the T-shaped limiting groove 701 and the T-shaped limiting block 702 not only realizes the rapid positioning and installation of the reinforced support plate 4, but also prevents the reinforced support plate 4 from shifting in the horizontal direction, ensuring the reinforcement effect. This structure is simple and reliable, easy to install and disassemble, and reduces construction difficulty and time cost.

[0026] refer to Figures 1-4As shown, the top surface of the reinforcing support plate 4 is in contact with the bottom surface of the platform steel beam 2. Triangular brackets 5 are fixedly installed on the left and right sides of the bottom supporting steel column 1 below the reinforcing support plate 4 using bolts. A U-shaped limiting plate 6 is fixedly installed on the top surface of the triangular bracket 5, and the bottom surface of the reinforcing support plate 4 is inserted into the U-shaped limiting plate 6. The triangular brackets 5 further enhance the platform's support structure and improve its resistance to deformation under heavy loads. The U-shaped limiting plate 6 provides vertical positioning for the reinforcing support plate 4, ensuring that it stably supports the platform steel beam 2 and prevents it from swaying up and down. The bolt installation method facilitates the disassembly and replacement of the triangular brackets 5, making future maintenance convenient.

[0027] The implementation principle of this application's embodiment of a quickly detachable steel structure platform is as follows: First, the operator uses anchor bolts to securely fix the bottom support steel column 1 to the foundation surface through the mounting through holes on the bottom fixing plate 10. Then, the platform steel beam 2 is placed on top of the bottom support steel column 1. The L-shaped limiting plate 302 can be used to position the sides of the platform steel beam 2. Once the platform steel beam 2 is positioned and installed, and the protruding plate 301 is located between the two sets of limiting fixing columns 306, the operator rotates the rotating head 307, causing it to drive the screw 304 to rotate. The screw 304 then moves the mounting plate 305, causing the protruding plate 301 to move. Plate 301 is inserted between two sets of limiting and fixing columns 306, which enables the platform steel beam 2 to be quickly fixed to the bottom support steel column 1. During disassembly, the above steps are reversed, and the connecting and fixing mechanism 3 and the reinforcing support plate 4 are removed in sequence to quickly complete the platform disassembly. This device facilitates the quick connection and fixing between the bottom support steel column 1 and the platform steel beam 2 through the connecting and fixing mechanism 3, improving the efficiency of installation and disassembly. The installation of the reinforcing support plate 4 can further improve the stability of the steel structure platform. The whole process is simple to operate and can effectively improve the disassembly and assembly efficiency and the flexibility of use of the steel structure platform.
