Guangzhou steel structure construction need to prepare what?

Guangzhou steel structure in the construction of the first time to ensure that the Guangzhou steel plant installation smoothly, and to ensure the quality of construction, then we must do a good job before the steel structure of the preparation, so as to complete the work, then the Guangzhou steel construction needs Do what to prepare it, wins the state steel structure for everyone to analyze.

First, the material, semi-finished products
1. Steel components: steel components model, the quality of production should meet the design requirements and construction specifications, should be factory certificate and should meet the relevant technical conditions.

2. Connection materials: welding rods, bolts and other materials should be a quality certificate, and meet the design requirements and the relevant national standards.

3. Coating: anti-rust coating technical performance should meet the design requirements and the relevant standards, should have a product quality certificate.

4. Other materials: a variety of connectors to meet the construction requirements.

Second, operating conditions
1. According to the component list, check the number of approach components, check the factory certificate and the relevant technical conditions. 2.2.2 Check whether the components are damaged or deformed during loading, transport and stacking. Damaged and deformed components should be corrected or reworked. Damaged anti-rust paint should be added to fill, and check again for inspection procedures. 2.2.3 on the components of the dimensions, making holes, welding, etc. to check, make a record.

2. Steel structure components should be installed according to the installation package, site storage site to meet the site order installation and lifting equipment into and out of the venue needs.

3. Steel components sorting stacking, the larger the stiffness of the components can lay the mats horizontal stacking. Multilayer stacking should be on a vertical line.

4. The preparation of steel structure construction program, after approval to the construction team technology to the end.

5. Check the installation of bearing surface and embedded parts, to confirm the acceptance of qualified data.
