Description

Technical Field

[0001] This utility model relates to the technical field of steel structure construction measures, and specifically to a welding operation frame for large-section steel structure beams. Background Technology

[0002] During steel structure construction, cages are typically used to install and weld steel beams. However, cages are no longer suitable for installing and welding large-section steel beams, making it difficult to install and weld steel beams at height. The operating scaffolds erected in the conventional way are prone to lateral displacement, which poses a significant safety hazard to personnel working on the scaffolds. Summary of the Invention

[0003] The purpose of this utility model is to solve the problem that it is difficult to set up a working platform during the installation and welding of large-section steel beams at high altitudes, and that the traditional method of setting up an operating frame poses safety hazards. Therefore, a steel structure installation hanging operating frame is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A steel structure installation hanging operating frame includes a rectangular frame main body constructed from uprights 1 and horizontal bars 2. Within the frame main body, a horizontal reinforcement layer and a construction work platform layer are provided; longitudinally, front and rear protective guards are provided for the steel structure main body; and an operating frame support is provided at the top of the frame main body. The frame reinforcement layer is located at the bottom of the steel structure main body, and the top is suspended from the operating frame support via connecting lugs. The front and rear protective guards are clamped on both sides of the steel structure main body.

[0006] The aforementioned steel structure installation hanging operation frame has connecting ear plates that are evenly and symmetrically welded to the top of the main steel structure. The number of these plates is determined according to the dimensions of the main steel structure. After passing through the connecting ear plates, the steel pipes are erected on the top of the main frame and fixed to form the operation frame support.

[0007] The aforementioned steel structure installation hanging operation frame has a construction operation platform layer located below the reinforcement layer, with scaffold boards 5 laid on top.

[0008] The aforementioned steel structure installation hanging operation frame, including the reinforcement layer, the construction operation platform layer, the vertical protective frame, and the top operation frame support, are all constructed from steel pipes.

[0009] The aforementioned steel structure installation hanging operation frame is characterized in that the number of vertical protective guards is 4, arranged in two parallel sets, with the upper and lower ends respectively connected to the horizontal bars of the frame body to clamp the steel structure body from the front and back.

[0010] Compared with existing technologies, the advantages of this utility model are:

[0011] 1. In this utility model, all-round constraint is adopted in the longitudinal, transverse and vertical directions, which can effectively ensure the stability of the operating frame, have good stress performance, and improve the safety performance during use.

[0012] 2. In this utility model, the operating frame is easy to set up and disassemble, and all materials can be reused, which can save costs.

[0013] 3. In this utility model, the steel pipe connecting ear plate used can be made from the connecting plate used in the steel structure installation process, and it is fixed to the main body of the steel structure by welding, which can effectively ensure that the operating frame will not shift to the side and improve safety performance.

[0018] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings. Example

[0019] Reference Figure 1 As shown, a steel structure installation hanging operation frame includes a rectangular frame main body erected by uprights 1 and horizontal bars 2. The frame main body is provided with a horizontal reinforcement layer and a construction operation platform layer; the steel structure main body is provided with front and rear protective guards in the longitudinal direction; and the operation frame support is provided on the top of the frame main body.

[0020] The connecting ear plates are uniformly and symmetrically welded to the top of the main steel structure. Their number is determined by the dimensions of the main steel structure; in this embodiment, four sets, totaling eight connecting ear plates, are welded. During use, the steel pipes at the top of the main frame pass through the connecting ear plates and are then erected and fixed on top of the main frame, forming a support for the operating frame. A reinforcing layer is installed at the bottom of the main steel structure, and vertical protective barriers (or baffles) are located on the front and rear sides of the main steel structure. Through the clamping action of the top operating frame support, connecting ear plates, reinforcing layer, and protective barriers, the main steel structure is fixed to the operating frame, achieving XYZ three-dimensional constraint and ensuring the stability and safety of the operating frame during construction. The construction platform layer is located below the reinforcing layer, and scaffold boards 5 are laid on top. All materials are reusable, thus saving costs and improving construction efficiency.

[0021] Specifically, the horizontal reinforcement layer and construction platform layer, the vertical protective frame, and the top operating frame support are all constructed of steel pipes. The four steel pipes at the top are spaced 0.6m, 1.2m, and 0.6m apart, with the larger spacing in the middle to avoid the welding space. The spacing between the connecting ear plates is also consistent.

[0022] There are four vertical protective guards, arranged in two parallel sets. Each guard is connected to a horizontal bar at both ends of the main frame, clamping the steel structure from front to back and thus creating vertical constraints on the operating frame. These protective guards can also be replaced by baffles.

[0023] During erection, steel pipes are passed through connecting lugs at the top of the main steel structure as the fixed ends of the operating frame. Then, uprights and horizontal bars are used to construct the rectangular frame of the operating frame. A reinforcement layer is built using steel pipes at the bottom of the main steel structure, followed by the construction platform layer. The members are fixed together using fasteners. Finally, scaffold boards are laid at the bottom of the operating frame to serve as the operating platform, where workers can perform steel structure installation and welding. The connecting lugs effectively fix the operating frame, restricting its lateral movement and ensuring construction safety. Furthermore, the operating frame is reusable, thus saving costs.

[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
