Installation method of ground steel structure

Steel structure is made of steel as building structure material, and ground steel structure is a type of Foshan steel structure. The ground steel structure is composed of beams, columns, rigid platform columns and guardrails. In the construction process, we should first install columns, then install beams, then platforms, and finally guardrails. The installation of ground steel structures is the first step in the installation of any kind of equipment. Today we will talk about the installation method of the ground steel structure.
1. steel structure column installation
Steel columns are adjustable and non adjustable. Different structures are used in different locations.
2. steel structure cross beam installation
With the top support of the column, it is convenient to install. The connection between the crossbeam and the top of the column is usually fixed by welding or splint, and has the advantages of dismantling and good stability.
Installation of 3. steel structure longitudinal beam
There are two kinds of direct welded and bolted connections for the insertion beam. The longitudinal beam and the steel platform are installed continuously from one side to the other side during installation.
Installation of 4. steel structure platform
The steel structure platform has two kinds of modular and integral. The mode of the modular steel platform is installed directly on the steel structure or in the middle of the beam after the installation of the beam and the longitudinal beam. The integral type is a direct connection between the steel structure beam and the platform.
5. steel structure staircase and guardrail installation
There are two kinds of slanting ladder or straight ladder. Generally, the ladder is heavier and the straight ladder is lighter. When installation, a hand hoist can be hung above the platform, the ladder is vertical and the platform is placed on the ground below the corresponding platform. The lower end of the gourd is tied up at the top of the ladder, and the position is adjusted to the installation position and the upper part is welded with the platform beam welding. Then, the lower part is fixed with the expansion bolt.
The above is the installation method of the Foshan steel structure to the ground steel structure. The most important thing is to ensure the quality of the construction and avoid unnecessary trouble in the later stage.
