Material selection of roof panels and wall panels in the construction of steel structure engineering such as the installation of steel structure car exhibition hall.
1. The selection of all walls and roof panels of the steel structure car exhibition hall is particularly important. Generally, the operating cycle of an automobile exhibition hall is 15-20 years, so the selected materials are good-looking, beautiful, and have a long service life. Replacement or maintenance can still continue to use.
2. The stress-bearing parts of the steel structure automobile exhibition hall are generally made of steel. In order to save the cost, you can directly use the finished profiles such as: I-beam, hot-rolled n-beam, round tube, square tube and other profiles. The material can be QC24EB, Q845B, Q835 steel. At present, Q355B steel has replaced Q345B steel. If you can buy Q345B steel, the price will be cheaper.
3. The walls of steel structure car exhibition halls generally use broken glass, metal plates, stones, etc. as wall decoration materials. In order to look beautiful, boards such as wood boards and cement boards are generally used as decorations.
4. The roof of the steel structure exhibition hall is generally made of cheap color steel plate or a layer of concrete is poured on the color steel plate. The drainage generally adopts two situations of organized or unorganized drainage. Organized drainage is relatively troublesome. To find out the overall slope of the roof, you also need to install drainage pipes to connect with the ground drainage ditch to form a drainage system. If the roof has unorganized drainage, it is only necessary to find a good slope for the roof, and the rainwater can be freely drained to the ground by protruding about 1 meter around the roof.
5. The steel structure exhibition hall needs to be planned by Party A or the architectural designer or home decoration designer according to the site, such as plan, space, and regional function use. The steel structure designer arranges the steel structure components according to the architectural drawings.
6. The installation work of the steel structure exhibition hall needs to be arranged. According to the structural design drawings of the steel structure designer, the steel structure hook components can be processed in the steel structure processing plant. After the components of the steel structure beams and columns are processed, they are transported to the site to be installed for hoisting, installation, welding and other operations. When hoisting and installing, special and certified staff members need to direct the work on site.
7. The installation sequence of the steel structure car exhibition hall is generally: foundation foundation-embedded parts-steel columns-steel beams-horizontal connection-roof secondary beams-roof rice-wall. Among them, safety must be paid attention to when installing the glass ball, because the wall glass-generally uses a K glass surface with a large width as the actual decorative panel.
