Device precision control: messy space steel structure should be measured and controlled in the installation, because Fujian steel structure construction measurement control as a part of the construction skills, the rationality and advanced nature of the project construction plan, from a lot of measurement and control data information analysis results and get reaction and proof.
Before construction of steel structure, measure the overall structure level and pop out horizontal lines on the wall. If there is a screed, be sure to remove first. The purpose is to bring the frame beam close to the load-bearing wall. Conducive to stress, then draw the exact location of each bolt hole.
The thickness of light steel keel is between 0.4mm and 2.0mm. Generally speaking, the design scheme will be based on improving the net weight of raw materials to choose the main keel of different thickness, to ensure the bearing capacity of the main keel, such as the use of paper gypsum board ceiling, will choose the thin thickness of light steel keel, and the thickness of plaster of Paris is thick will choose a large thickness of light steel keel.
Steel structure is closely related to the reconstruction of historic buildings and has irreplaceable advantages in this new industry. From the perspective of engineering building reconstruction, steel structure has the advantages of flexibility, strong attraction and strong adaptability.
