Installation of steel beam in steel structure factory building

Steel structure factory building is an industrial factory building with steel as the main building material, which has the advantages of high strength, good durability and short construction period. Among them, steel beams are an important part of the steel structure factory building, and they play the role of bearing the weight of the factory building and dispersing the load. In the construction process of steel structure workshops, the installation of steel beams is a key step. Below we will introduce the installation process of steel beams in detail.

First of all, the installation of steel beams requires detailed construction scheme design and construction drawings. The formulation of the construction plan needs to take into account factors such as the size, shape, and quantity of the steel beams, as well as the site environment and construction conditions. The formulation of construction drawings needs to accurately indicate information such as the position, connection method, and installation sequence of steel beams, so that construction personnel can install them according to the drawings.

Second, the installation of steel beams requires on-site pretreatment. First of all, the ground in the installation area needs to be cleaned and leveled to ensure the flatness and bearing capacity of the installation area. Then, foundation construction needs to be carried out, including digging foundation pits, pouring concrete, etc., to provide a stable support platform. In addition, it is necessary to check and adjust the levelness and verticality of the foundation to ensure the installation accuracy of the steel beam.

Next, the installation of the steel beams requires hoisting and positioning. Generally, the lifting of steel girders is carried out by using a crane or a crane. During the hoisting process, it is necessary to accurately hoist the steel beam to the designated position according to the marks and size requirements on the construction drawings. At the same time, auxiliary tools such as slings or spreaders need to be used to ensure the stability and safety of the steel beam.

After the hoisting of the steel beams is completed, the connection and fixing of the steel beams need to be carried out. Typically, steel girders are joined by welding, bolting, etc. When welding, it is necessary to follow the relevant safety operation regulations to ensure the welding quality and connection strength. When bolting, it is necessary to use appropriate bolts and connectors to ensure that the connection is firm and reliable.

Finally, after the installation of the steel beams is completed, acceptance and inspection are required. The purpose of acceptance and inspection is to ensure the installation quality and safety of steel beams. During the acceptance and inspection process, it is necessary to conduct a comprehensive inspection of the position, connection, fixing, welding, etc. of the steel beam to ensure that it meets the design requirements and construction standards.

In short, the installation of steel beams is an important link in the construction of steel structure factory building, which is related to the safety and stability of the workshops. During the installation of steel beams, it is necessary to carry out detailed construction scheme design and formulation of construction drawings, carry out on-site pretreatment, carry out hoisting and positioning, carry out connection and fixing, and carry out acceptance and inspection. By operating in strict accordance with the construction requirements and standards, the installation quality and safety of the steel beams can be ensured, providing a good foundation for subsequent engineering construction.
