Grid engineering is a structural form often used in the field of modern architecture, commonly used in large public buildings such as stadiums, bridges, and exhibition halls. The production of grid engineering involves a number of links and processes, and certain quality standards must be followed to meet the design requirements and safety standards.
First, the production process.
1.1. Design: The grid project is made in accordance with the design drawings, so the design link is the first step in the production of the grid project. The designer needs to develop a reasonable grid structure design scheme through the comprehensive consideration of the size, shape, load and wind load of the building. The design scheme should meet the requirements of structural strength, stability and safety, and the waste of materials should be minimized while achieving the design effect.
1.2. Material preparation: The production materials of the grid project generally include steel, connectors and covering materials. In the material preparation stage, it is necessary to select the appropriate material according to the design scheme and inspect the material to ensure that its quality meets the requirements. When making steel, it is important to consider indicators such as dimensional accuracy, surface quality, and mechanical properties to ensure compliance with the relevant standards. The quality of the connector is the key to the grid project, and the connector must be selected to meet the standard, and its strength, hardness and corrosion resistance and other indicators must be tested. The choice of covering material should also consider its performance and quality, such as waterproof, windproof and other indicators.
1.3. Cutting and welding: The production of grid engineering requires cutting, sawing and welding of steel. Cutting and sawing requires high precision, flat cuts, and the avoidance of defects such as cracks and hydrogen absorption. When welding, it is necessary to pay attention to preheating, welding temperature and the quality of welded joints, which must comply with relevant standards and specifications.
1.4. Assembly and adjustment: The assembly of grid engineering is to assemble the cut and welded parts together. In the assembly process, high precision, stable structure, and ensure that the corners of continuous steel plates and steel pipes are not deformed. Adjustment is to check and correct the entire grid to ensure that the overall structure is horizontal, vertical and stable.
1.5. Surface treatment and anti-corrosion: After the production of the grid project is completed, surface treatment and anti-corrosion work are required. Surface treatments include rust removal, painting, and spraying to protect the quality and aesthetics of the steel surface. The selection of anticorrosive coatings should consider their anti-corrosion performance, hardness and surface flatness.
Second, quality standards.
2.1. Steel quality requirements: The quality of steel used in the grid project should meet national standards, such as "Q235B Steel Technical Conditions". There shall be no cracks, creases, twist scars, cracks and other defects on the surface of the steel, and the steel plate shall be bent and formed without cracks. The mechanical properties of the steel are required to meet the design requirements, such as tensile strength, yield point and impact toughness.
2.2. Quality requirements of connectors: Connectors are an important part of the grid project, and their quality directly affects the stability and safety of the entire grid. The connectors should meet the design requirements, and the connectors must meet the national standards, such as the "Technical Specifications for the Fabrication and Installation of Steel Structures". The specifications and materials of the connectors should match the steel, and the welded joints should meet the relevant technical standards.
2.3. Surface treatment and anti-corrosion requirements: The surface treatment of the grid project should meet the design requirements, such as spraying, painting, electroplating and other processes. The surface quality should reach a certain standard and ensure anti-corrosion performance. The selection of anti-corrosion coatings should also comply with relevant standards and adhere to the standard process of coating application to ensure the quality of anti-corrosion.
2.4. Construction and installation quality requirements: The construction and installation requirements of the grid project conform to unified standards and relevant regulations. Design requirements must be strictly adhered to, and construction and installation must be error-free. The foundation, supports, and connections of the building must be strong and strong, and the structural parts must be in harmony with each other. The installation process must strictly comply with the safety procedures and operating specifications, and take effective safety measures to ensure safety.
In short, the production process and quality standards of the grid project determine its structural stability and safety, which must be comprehensively and strictly implemented to ensure that the quality of the entire project meets the design, construction and installation requirements.
