Anti-throwing nets, as an important safety protection facility, are widely used in bridges, highways, urban buildings and other areas to effectively prevent safety hazards caused by high-altitude throwing. This article will comprehensively analyze the construction process of anti-throwing nets, from design, material selection, production to installation, to present readers with a complete anti-throwing net construction process.
1. Design principles
The design of anti-throwing nets must follow strict safety standards and specifications. Before design, a detailed on-site survey of the installation area is required, including comprehensive consideration of factors such as terrain, climate, and usage requirements. The design principles mainly include structural stability, mesh size suitability, anti-corrosion durability, etc. Structural stability ensures that the anti-throwing net can remain stable under extreme weather conditions; the mesh size needs to be determined according to actual needs, not only to prevent small objects from passing through, but also to consider ventilation and aesthetics; anti-corrosion durability requires that the anti-throwing net material has good corrosion resistance and extends its service life.
2. Material selection
The material selection of anti-throwing nets is crucial and directly related to its protective effect and service life. Common anti-throwing net materials include low-carbon steel wire, angle steel, steel plate mesh, etc. Low-carbon steel wire is widely used due to its good toughness and welding performance; angle steel is the main material for columns and frames, providing sufficient support strength; steel plate mesh is the preferred material for mesh because of its uniform mesh and high strength. In addition, the connectors and fasteners of the anti-throwing net must also be high-quality products to ensure the stability of the overall structure.
3. Production process
The production process of the anti-throwing net includes mesh cutting, frame making, column welding, anti-corrosion treatment and other steps. First, according to the construction drawings and technical requirements, the steel plate mesh is cut into the specified size and quantity. Then, the angle steel is made into a grid frame according to the design drawing and welded using an arc welding machine. The production of the column also follows the design drawings, and the angle steel is welded into the required shape and size. After the production of the mesh, frame and column is completed, the welding slag and anti-corrosion treatment are required. Anti-corrosion treatment generally uses hot-dip galvanizing or spraying anti-corrosion paint to improve the corrosion resistance of the anti-throwing net.
4. Installation steps
The installation process of the anti-throwing net must follow strict construction specifications and safety requirements. First, fix the finished columns in the installation area according to the predetermined position and spacing. The columns are usually fixed by expansion bolts or welding to ensure the stability of the columns. Then, fix the mesh pieces to the columns and frames one by one, and fasten them with screws or buckles. During the installation process, it is necessary to ensure that the mesh pieces are flat, tight, and not twisted or loose. After the installation is completed, the entire anti-throwing net structure needs to be inspected and adjusted to ensure that it meets the design requirements and safety standards.
5. Post-maintenance
The post-maintenance of the anti-throwing net is equally important. Regularly check whether the connectors and fasteners of the anti-throwing net are loose or damaged, and replace or repair them in time. At the same time, attention should be paid to the anti-corrosion performance of the anti-throwing net. If corrosion is found, anti-corrosion treatment should be carried out in time. In addition, it is necessary to clean up the debris and dirt on the anti-throwing net to keep it ventilated and beautiful.
