Grid roof processing is an important building construction, which can not only provide stable support and protection for the building, but also increase the aesthetics and functionality of the building.
This article will discuss the processing of grid roofs, including its definition, material selection, processing, etc.
1. Definitions. Grid roof is a form of roof with a grid-like structure as the main body, which forms a grid structure through steel or other materials crossed horizontally and vertically, and then is fixed on the top of the building through connectors.
The grid roof has the characteristics of lightweight, sturdy and light transmission, and is widely used in stadiums, exhibition halls, commercial complexes and other construction projects.
Second, the selection of materials.
1.Steel: one of the commonly used grid roofing materials, which has the characteristics of high strength, corrosion resistance and easy processing.
Common steels are Q235, Q345, etc., and suitable steel can be selected according to the specific use environment and requirements.
2.Aluminum alloy: Aluminum alloy grid roof has the advantages of light weight, corrosion resistance, easy processing, etc., and is suitable for some places with high weight requirements, such as airports, stations, etc.
3.FRP (Glass Fiber Reinforced Plastic): FRP grid roof has the advantages of light weight, good light transmittance, corrosion resistance, etc., and is suitable for some places with high requirements for light transmittance, such as swimming pools, greenhouses, etc.
3. Processing. 1.Design and drawing: According to the architectural design requirements and the actual construction situation, the design and drawing of the grid roof are carried out.
The design should take into account factors such as the stability of the structure, the selection of materials and processing.

2.Material processing: According to the drawing requirements, the steel or other materials are cut, welded and other processed to make the components of the grid roof.
3.Assembly and installation: The processed components are assembled according to the design requirements and installed on the top of the building.
During the assembly process, it is necessary to pay attention to the connection mode and installation sequence between the components to ensure the stability and safety of the grid roof.
4.Anti-corrosion treatment: Grid roofs generally need anti-corrosion treatment to improve their corrosion resistance.
Commonly used anti-corrosion treatment methods include hot-dip galvanizing, spraying anti-corrosion paint, etc.
5.Light transmission treatment: For some grid roofs with high light transmission requirements, light transmission treatment can be carried out, such as coating transparent sunscreen film, installing transparent glass, etc.
Fourth, the application case.
1.Bird's Nest Stadium: The Bird's Nest Stadium is the main venue of the 2008 Beijing Olympic Games, and its grid roof is made of a large amount of steel, forming a unique bird's nest shape, which has become one of Beijing's landmark buildings.
