Installation and connection of building steel structure

Architectural steel structure is a common structural form in modern buildings. It has the advantages of high strength, good stability, and strong durability, so it is widely used in industrial plants, commercial complexes, stadiums and other buildings. However, this structure also has its own installation and connection characteristics that require special attention.

Preparations before installation

Before the installation of the building steel structure, it is necessary to carry out detailed design and drawing work, determine the size, material, weight and other information of each component, and make detailed construction drawings. At the same time, it is necessary to carry out on-site survey and measurement to determine the topography, soil quality and foundation conditions of the site, so as to formulate the construction plan of the steel structure.

Installation steps

1. Installation of standing members

The standing member is one of the most important members in the steel structure, and its installation requires professional equipment and technology. Before installation, it is necessary to determine the position and height of the standing member, and then use lifting equipment to install it on the support point. During the installation process, attention needs to be paid to ensuring the verticality and levelness of the standing components to ensure the stability of the entire structure.

2. Installation of beams and suspension components

Beams and suspension members are important members connecting standing members in steel structures. Before installation, it is necessary to determine the position and size of the beam and suspension components according to the design requirements. Then, it is mounted on a standing member with lifting equipment, adjusted and fixed. During the installation process, care should be taken to ensure the levelness and verticality of the beams and suspension components to ensure the stability of the structure.

3. Floor and roof installation

The floor and roof are important parts of the steel structure, and their installation needs to be carried out according to the design requirements. Before the installation, the foundation needs to be constructed first, and then the floor and roof elements are installed on the beams and suspension elements. During the installation process, attention needs to be paid to ensure the accuracy of the position and size of the components to ensure the stability of the structure.

Connection method

In building steel structure, connection is a very important link. The quality of the connection directly affects the stability and safety of the entire structure. The common connection methods are as follows:

1. Solder connection

Welding connection is a commonly used connection method, and its advantages are high connection strength and good stability. Before the welding connection, the components of the connection part need to be polished and cleaned to ensure the quality of the welded joint.

2. Bolted connection

Bolt connection is a commonly used connection method, and its advantages are convenient installation and easy disassembly. Before bolting, it is necessary to select appropriate bolts and nuts and conduct strict inspections to ensure the quality of the connection.

3. Anchor connection

Anchor connection is a commonly used connection method, and its advantages are high connection strength and good stability. Before the anchor connection, it is necessary to carry out detailed design and calculation, and select appropriate anchor materials and equipment to ensure the quality of the connection.

In short, the installation and connection of building steel structures requires detailed design and drawing work, professional equipment and technology, and attention to details and safety during the construction process to ensure the stability and safety of the entire structure.
