What measures does your company take to control the quality of the workshop steel structure？
The load-bearing components of the workshop steel structure are welded, assembled and assembled by steel material, which can be applied to factories, warehouses, office buildings, gymnasiums, farms, etc. It is not only suitable for single-story large-span buildings, but also for building multi-story or high-rise buildings. It has the advantages of good sealing performance, good fire resistance, good seismic performance, durability, convenient transportation, easy maintenance, environmental protection and energy saving. In the process of designing, manufacturing and installing the workshop steel structure, our company advocates that the first thing to ensure is quality and safety, focusing on "precision control" and emphasizing details. Therefore, the measures taken by our company for the quality control of the workshop steel structure are as follows:
1. Measurement control
During the production and installation of the steel structure, the measuring instruments and tools must be inspected by the technical supervision department. At the same time, attention should be paid to whether the accuracy of these instruments and tools match the production requirements of the steel structure.
2. Process control
In the manufacturing process of steel structures, high-precision processing methods should be used to predict the various deformations that may occur during each process and take corresponding defensive measures. If the shrinkage deformation caused by welding, it is necessary to take the release to eliminate the margin. Small deformation welding, automatic symmetry welding method, etc.
3. Embedded control
Pre-buried anchor bolts are the key task of the steel structure installation construction site. Our company will prepare a special construction plan and accurately construct it. Under normal circumstances, before our company irrigates the tunnels, the supervision engineer must perform a closed measurement inspection on the embedded bolts. In addition to the vertical and horizontal axis measurement, the elevation inspection is also required. Before the pouring tunnel is initially set, a retest should be performed again to ensure that the anchor bolts are accurately embedded.
4. Assembly control
The steel structure assembly generally adopts the plane assembly method, which requires high precision. Our company usually requires pre-assembly in the factory to simulate the actual working conditions of the construction site.
5. Anti-corrosion and fire-proof coating control
(1) Anticorrosive coating
The anti-corrosion of steel structure is mainly divided into two types: anti-air corrosion and anti-soil corrosion. The coating is generally divided into four layers: primer, transition layer, intermediate layer and surface layer. In addition to controlling the coating thickness and coating process requirements, the supervision engineer must also master the basic properties of various coating materials to effectively control the project under supervision. If you are in coastal areas and areas with long sunshine, you must pay attention to choosing paints that prevent ultraviolet rays, salt and acid corrosion.
(2) Fireproof coating
Steel structure buildings have higher fire resistance requirements, and their fire resistance rating is closely related to the fire resistance rating. Under the same fire resistance rating, the fire resistance ratings of different components such as beams, columns, and plates are different. Therefore, in the work, it is necessary to carefully check the fire resistance limit of the main steel structure components and the thickness of the fire protection coating according to the drawings.
