Steel grating, as a high-strength and easy to maintain metal component, is widely used in industrial platforms, municipal engineering, sewage treatment and other scenarios. The installation and construction quality directly affects the safety and lifespan of use, and it is necessary to follow standardized procedures for operation.
The preparation work before construction is crucial. Firstly, it is necessary to verify whether the model, specifications, and design drawings of the steel grating are consistent, and to check whether there are any deformation, corrosion, or other issues with the plates. Calculate the required material quantity based on the construction area and prepare installation tools, including wrenches, level gauges, tape measures, welding equipment, etc. At the same time, the installation site should be cleaned to ensure that the foundation structure is flat and solid. The flatness of the concrete base or steel structure support should be tested to ensure that the error is controlled within a reasonable range.
The core process of installing steel grating includes three steps: positioning and laying out, laying and fixing, and joint treatment. When positioning, it is necessary to pop up installation control lines according to the design drawings, determine the laying direction and layout of the grating board, and avoid narrow strips or irregular boards. The laying should be carried out block by block from the reference point, and appropriate expansion joints should be reserved between adjacent boards to prevent deformation caused by temperature changes. For platform installation, it is necessary to ensure that there is sufficient overlap length between the grating plate and the support beam, and that each plate has at least two support points.
The fixed method should be selected according to the usage scenario. It is recommended to use welding fixation in industrial heavy-duty areas. Spot welding should be carried out around the grid plate and at the junction with the support beam. After welding, welding slag should be removed and anti-corrosion treatment should be carried out. For areas that require disassembly, specialized installation clips can be used to secure them. Each board needs to be equipped with a sufficient number of clips, and the number of fixing points for edge boards needs to be increased.
Quality control during installation cannot be ignored. Check the surface flatness of the grille with a level to ensure overall flatness; Test the fixed strength to ensure that the welding point has sufficient tensile strength. Special attention should be paid to the cutting treatment of irregular parts. The incision should be polished smooth and coated with anti rust paint to avoid safety hazards caused by sharp edges. For multi-layer platform installation, layered acceptance is required to ensure that the hole positions of the upper and lower grilles correspond.
Safety regulations are the basic requirements for construction. Operators must wear non slip shoes, safety helmets, and protective gloves, and fasten their safety belts when working at heights. Warning signs should be set up in the installation area to prohibit non construction personnel from entering. Fire extinguishing equipment should be equipped during welding operations to prevent sparks from igniting debris. After the construction is completed, the site should be cleaned of debris and checked for loose grating panels or protruding fasteners to ensure the overall structural safety and stability.
