Description

Technical Field

[0001] This application relates to the technical field of steel pipe scaffolding erection on cantilevered I-beams, and in particular to a welding-free scaffolding fixing device for cantilevered I-beams. Background Technology

[0002] Cantilevered I-beams are a common building structure, primarily used in locations requiring cantilevered extensions, such as rooftops and balconies. They offer advantages such as ease of construction, versatility, and high load-bearing capacity, making them an indispensable part of building structures. The cantilever beam's tail end should be fixed to a reinforced concrete beam-slab structure at two or more points to ensure structural stability and safety. In high-rise building cantilever structures, the cantilevered I-beam is the main load-bearing component, responsible for supporting the entire weight of the cantilever structure and ensuring the building's stability.

[0003] Cantilevered I-beam scaffolding is a special type of scaffolding commonly used in the construction of high-rise buildings or bridges. It relies on cantilevered I-beams suspended from the building for support and is suitable for scenarios requiring construction, maintenance, or other work at heights, such as the exterior walls of high-rise buildings, large bridges, and chimneys. In these scenarios, cantilevered I-beam scaffolding provides construction workers with a stable working platform, allowing them to work more conveniently and safely.

[0004] Currently, the cantilevered I-beam scaffolding is under construction, as per the instructions attached. Figure 1-2 As shown, it is necessary to weld positioning and fixing points (such as connecting plates) of steel pipe scaffolding onto the I-beam, weld the scaffolding to the connecting plate, or weld connecting pipes through or embedded in the scaffolding steel pipes onto the connecting plate to ensure the stability of the scaffolding. However, welding will damage the steel beam base material, require more manpower and resources to increase the operation, and cutting is inconvenient, making it difficult to erect and fix the scaffolding steel pipes on the cantilevered I-beam. Summary of the Invention

[0005] To address the aforementioned problems, this application aims to provide a welding-free scaffolding fixing device for cantilevered I-beams, which solves the drawbacks of current welding methods that damage the base material of the I-beam and make subsequent cutting inconvenient. It enables the rapid erection of scaffolding steel pipes without damaging the I-beam.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a cantilever I-beam weld-free scaffolding fixing device, characterized in that: the fixing device is detachably connected to the I-beam, and the fixing device includes an assembly component connected to the I-beam, and a positioning connection component provided on the assembly component to connect to the steel pipe of the scaffolding.

[0007] Preferably, the assembly component includes an assembly plate that is flush with the upper surface of the I-beam, and locking screws are symmetrically and rotatably installed on both sides of the I-beam on the assembly plate, and the bottom of the locking screws is configured as a curved section that is flush with the inner surface of the I-beam.

[0008] Preferably, the positioning connection component is a positioning connection pipe in which a steel pipe for embedding or covering the scaffold is provided on the top surface of the assembly plate.

[0009] Preferably, a tightening screw is also provided at the end face of the curved section, and a clamping body with a certain surface area is rotatably connected to the end of the tightening screw, which is in contact with the side wall of the I-beam.

[0010] The beneficial effects of this application are: the fixing device can achieve the assembly connection between the fixing device and the I-beam through the assembly components, solving the drawbacks of the current method which requires welding, causing damage to the base material of the I-beam, and making subsequent cutting inconvenient. After assembly, the scaffolding steel pipes are positioned and connected by the positioning connection components, thereby enabling the rapid erection of the scaffolding steel pipes without damaging the I-beam.

[0019] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] See attached document Figures 3-7 The diagram illustrates a weld-free scaffolding fixing device for cantilevered I-beams. This device is detachably connected to the I-beam 1 and includes an assembly component connected to the I-beam 1, and a positioning connection component on the assembly component that connects to the steel pipes 2 of the scaffolding. The assembly component enables the fixing device to be assembled and connected to the I-beam, overcoming the drawbacks of welding which damages the base material and makes subsequent cutting difficult. After assembly, the positioning connection component positions and connects the scaffolding steel pipes, allowing for rapid erection of the scaffolding steel pipes without damaging the I-beam.

[0021] Specifically, such as Figure 3-4 As shown, the assembly component includes an assembly plate 3 that is flush with the upper surface of the I-beam 1. A locking screw 4 is symmetrically mounted on both sides of the assembly plate 3 and rotatably passes through it. The bottom of the locking screw 4 is configured as a bent section 41 that is flush with the inner surface of the I-beam 1. During assembly, first as follows... Figure 4 As shown in the attached diagram on the left, the locking screw 4 is rotated so that its bent section 41 faces outward, facilitating the downward movement of the assembly plate 3 to flush against the upper surface of the I-beam 1. Preferably, a rubber pad 8 is also pressed between the assembly plate 3 and the upper surface of the I-beam 1 to provide cushioning and anti-slip properties. (The rest of the text is missing.) Figure 4 As shown on the right, the locking screw 4 is rotated in the opposite direction so that its bent section 41 is flush with the inner surface of the I-beam 1. Then, the locking nut 9 is fitted on the upper side of the mounting plate 3 of the locking screw 4, thus achieving the overall fastening assembly with the I-beam 1.

[0022] After the above assembly, to facilitate the positioning and connection of the steel pipes 2 of the scaffolding, as follows: Figure 3-4 As shown, the positioning and connecting component is a positioning connecting pipe 5 on the top surface of the assembly plate 3, which is embedded or sleeved with the steel pipe 2 of the scaffold. By sleeved or embedded in the positioning connecting pipe 5, the horizontal steel pipes can be connected, thus quickly realizing the non-destructive erection of the scaffold steel pipes on the I-beam.

[0023] The problem arises when the bent section 41 of the locking screw 4 rotates and detaches from the bottom surface of the I-beam 1 due to external construction forces. Figure 5-7 As shown, a tightening screw 6 is also installed at the end face of the bent section 41. After the above assembly is completed, the tightening screw 6 is rotated to extend it and abut against the side wall of the I-beam 1. Under this abutting contact, the problem of the bent section 41 rotating and separating from the bottom surface of the I-beam caused by external construction forces is overcome, ensuring the stability and safety of the assembly. At the same time, the contact between the tightening screw 6 and the side wall of the I-beam 1 restricts the rotation of the locking screw 4, thereby preventing the synchronous rotation of the locking screw 4 when the locking nut is rotated and tightened, improving the convenience of the assembly operation.

[0024] Because the contact area between the end face of the tightening screw 6 and the I-beam 1 is limited, under the action of large construction forces, the tightening screw 6 may still detach from the side wall of the I-beam 1. Therefore, to enhance the contact tightness of the tightening screw 6, further measures are needed, such as... Figure 6-7 As shown, a clamping body 7 with a certain surface area is rotatably connected to the end of the tightening screw 6, which is in contact with the side wall of the I-beam 1. The contact width of the clamping body 7 along the length of the I-beam 1 is greater than the outer diameter of the end face of the tightening screw 6. Therefore, when the bent section 41 is affected by external construction forces, the clamping body 7 can further restrict the deflection of the bent section 41, ensuring the stability of the assembly and improving construction safety. Preferably, a driving hole 6a is provided circumferentially on the tightening screw 6, and the rotation of the tightening screw 6 can be driven by a driving rod.

[0025] The principle of this application is as follows: During the assembly operation, the locking screw 4 is first rotated so that its bent section 41 faces outward and a rubber pad is pressed between the assembly plate 3 and the upper surface of the I-beam 1. Then, the assembly plate 3 is lowered to contact the rubber pad, and then the locking screw 4 is rotated in the opposite direction so that its bent section 41 is flat against the inner surface of the I-beam 1. Then, the top screw 6 is rotated so that the clamping body 7 is flat against the side wall of the I-beam 1. Finally, a locking nut is fitted on the upper side of the locking screw 4 on the assembly plate 3, thus achieving the overall fastening assembly with the I-beam 1.

[0026] After the above assembly, the scaffolding steel pipes (vertical steel pipes) are sleeved or embedded in the positioning connecting pipes 5, and the horizontal steel pipes can be connected, thus quickly realizing the non-destructive erection of scaffolding steel pipes on the I-beams.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this application. Various changes and modifications may be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
