Description

Technical Field

[0001] The utility model relates to the technical field of highway equipment, in particular to a steel plate mesh anti-throwing net used for highway bridge construction safety. Background Art

[0002] Highway bridge construction safety has always been the focus of attention in the field of engineering construction. During the construction process, effective measures need to be taken to prevent objects from falling from heights to protect the lives of workers and passers-by. Traditional anti-falling nets are usually made of materials such as steel mesh or wire mesh. However, these materials have some problems during use. Steel mesh or wire mesh is prone to rust and corrosion, especially in humid or harsh environmental conditions, and its service life will be greatly shortened. This not only affects the aesthetics of the anti-falling net, but may also cause the strength of the mesh to decrease, increasing safety hazards. In addition, the mesh holes of steel mesh or wire mesh are large, and some small objects may not be able to be prevented. Ineffective blocking, thereby reducing the protective effect of the anti-throwing net. During the installation process, the existing steel plate mesh anti-throwing net is usually fixed to the guardrail of the bridge through the fixed columns at both ends of the protection net by bolts, and the steel plate mesh and the fixed columns in the existing guardrail are usually welded between the fixed columns. It is inconvenient to replace and disassemble after installation. At the same time, the overall replacement cost is high when replacing. In terms of safety, the two ends of the mesh protection net are welded to the fixed columns, and the structure is not stable enough. It is easy to be deformed or damaged by external forces. During the installation process, if the fixation is not firm, it may also cause the anti-throwing net to loosen or fall off. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem solved by the utility model is to provide a steel plate mesh anti-throwing net for safe highway bridge construction, which solves the problems of the existing steel plate mesh anti-throwing net being inconvenient to disassemble, having an unstable structure and having low flexibility.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: a steel plate mesh anti-throwing net for safe highway bridge construction, characterized in that: it includes a supporting frame, there are multiple supporting frames, and multiple connecting grooves are arranged on the supporting frame; a fixing part is fixedly arranged at the lower end of the supporting frame; multiple steel plate meshes are arranged between the supporting frames, and the steel plate meshes are connected to the supporting frames through connecting grooves; a groove is arranged on the fixing part, and a connecting piece arranged vertically with the supporting frame is arranged in the groove, and the connecting piece is arranged in an L-shaped structure; a fixing column is arranged between the supporting frames, and the fixing column is connected to the supporting net.

[0005] The beneficial effects of this solution are: through the vertically arranged fixing columns and the L-shaped connecting pieces arranged perpendicular to the fixing columns, the contact area between the L-shaped connecting pieces and the protective plate body is large, which improves the stability of the connecting pieces, and at the same time, both ends and the lower end of the steel mesh are limited and fixed, so that the steel mesh is very stable, and the steel mesh is connected to the supporting frame through the connecting groove, which is easy to install and improves the construction efficiency; the number and layout of the supporting frame and the steel mesh can be adjusted according to actual needs to meet the requirements of different highway bridge construction sites.

[0006] Furthermore, the connecting grooves are arranged in parallel on the support frame. Through the parallel connecting grooves, the external force on the steel mesh can be more evenly distributed on the support frame, avoiding the problem of local stress concentration. This helps to extend the service life of the anti-throwing net and reduce the risk of failure of the entire structure due to local damage. The parallel connection grooves make it easier to align and insert the steel mesh, simplifying the installation process and improving the efficiency of installation, which is very beneficial for large-scale construction or situations where frequent disassembly and reinstallation are required.

[0007] Furthermore, the fixing part and the supporting frame are welded, and welding can effectively prevent corrosion or loosening at the connection between the fixing part and the supporting frame. The metal joint formed by welding has good corrosion resistance, can remain stable for a long time under humid and harsh environmental conditions, and extend the service life of the anti-throwing net.

[0008] Furthermore, the connecting piece is cooperatively connected with the groove, which facilitates installation, increases the contact area between the connecting piece and the protective plate body and the fixing part, and improves the connection stability.

[0009] Furthermore, the end of the fixing column away from the steel plate mesh is arranged in an inclined structure. The inclined structure can provide better support and stability, so that the fixing column can better resist external force and prevent tilting. This design can reduce the possibility of shaking or deformation of the fixing column during use, thereby improving the overall stability and safety of the anti-throwing net. In the case of strong winds, the inclined structure can reduce the resistance of the fixing column to the wind and reduce the impact of the wind on the anti-throwing net. It can improve the wind resistance of the anti-throwing net and reduce the possibility of being blown down or damaged by the wind.

[0010] Furthermore, a limit piece is provided on the top of the fixed column, and a limit slot is provided on the limit piece to cooperate with the steel plate mesh. The design of the limit slot can limit the displacement of the steel plate mesh in the horizontal direction to prevent it from shaking or shifting during use. This increases the stability and safety of the anti-throwing net and reduces the potential safety hazards caused by the displacement of the steel plate mesh. If the anti-throwing net needs to be maintained or replaced, the steel plate mesh can be easily taken out of the limit slot for necessary maintenance or replacement operations. This detachable design facilitates daily maintenance and management.

[0011] Furthermore, a plurality of connection holes are provided on the fixing portion, and the connection holes penetrate the fixing portion and the connecting piece. Through the penetration of the connection holes, an integral structure is formed between the fixing portion and the connecting piece, thereby enhancing the strength and stability of the entire assembly, which is very important for applications that need to withstand large loads or operate in harsh environments. In addition, the penetration design of the connection holes increases the strength and stability of the connection, can better resist external forces and vibrations, and ensures that the connection between the components is firm and reliable.
