High Quality Multi-Storey Building Office Industrial Building Multi-Storey Steel Structure

High quality multi-storey building office industrial building multi-storey steel structure

Steel structure multi-storey building is a building with steel as the main load-bearing structure, usually with 4 to 6 floors. It has the characteristics of high strength and light weight, which can greatly reduce the foundation load. Due to the good toughness and ductility of steel, it has excellent seismic performance. In practical application, the large-span space is conducive to the flexible layout of commercial places; In the residential sector, it can realize free decoration design; Educational buildings can meet the needs of diverse functional zoning; In terms of public facilities, it ensures safety and space optimization; Industrially, it can carry large-scale equipment and plan floors according to the process. The prefabricated type is mostly used in the construction, and the components are assembled on site after the factory is prefabricated, which greatly shortens the construction period and has significant advantages in the field of modern construction.

Construction process:

Site leveling and foundation construction: First of all, the construction site is cleaned and leveled to ensure that the site has construction conditions. Carry out foundation construction according to the design requirements, such as pouring concrete foundations. During foundation construction, it is necessary to accurately position, reserve the installation holes or embedded bolts of the steel column, ensure the strength and stability of the foundation, and carry the weight of the upper steel structure.

Material procurement and inspection: according to the steel specifications and models determined by the design, the steel that meets the quality standards is purchased. After the steel enters the site, strict quality inspection is carried out, including appearance inspection (to see if there are cracks, bubbles, deformation and other defects), mechanical property testing (tensile test, impact test, etc., to ensure that strength, toughness and other indicators meet the standard) and chemical composition analysis, to prevent unqualified materials from being used in engineering.

Component processing and production: processing and production of steel in the factory according to the design drawings. Through cutting, welding, drilling and other processes, the steel is processed into various components such as steel columns, steel beams, and supports. In the process of processing, the dimensional accuracy is strictly controlled, the welding part is tested for non-destructive testing to ensure the quality of the components, and the numbering and identification are done after the completion to facilitate on-site installation.

Steel column installation: use a crane to lift the processed steel column to the top of the foundation, align the foundation reserved hole or embedded bolts and slowly put down, adjust the verticality and plane position of the steel column, fix it through temporary support, and carry out the final bolt fastening or secondary grouting fixation after the measurement is correct. During the installation process, it is necessary to ensure that the verticality deviation of the steel column is within the allowable range, so as to lay the foundation for the subsequent installation of the steel beam.

Steel beam installation: After the steel column installation is completed and fixed firmly, the steel beam is installed. The steel beam is also lifted to the installation position with the help of a crane and connected with the steel column by welding or high-strength bolts. Pay attention to the levelness and camber of the steel beam during installation, and adjust it according to the design requirements to ensure that the structural force is reasonable. The main load-bearing steel beams are installed first to form a stable frame system, and then the secondary steel beams and supporting members are installed.

Overall correction and fastening of the structure: After the installation of some components is completed, the entire steel structure frame is corrected as a whole, the verticality of the steel column, the horizontality of the steel beam and the overall size of the structure are measured, and the deviation is found to be adjusted in time. After the adjustment is completed, the bolts of all connection parts are re-screwed to reach the specified torque value, ensure that the connection is firm, and make the entire steel structure form a stable force system.

Why choose us:

At the design level, the company brings together senior designers in the industry, using cutting-edge modeling software and rich experience to deeply understand customer needs and customize exclusive design solutions. From the beginning of the project, the structural layout was accurately planned according to the building use and site conditions, taking into account the aesthetics and function, and the component size and connection method were repeatedly scrutinized and optimized to ensure that the design not only met the mechanical properties, but also improved the space utilization rate, and endowed the building with flexible characteristics.

In terms of steel selection, the company works closely with large-scale high-quality steel mills to build a strict material selection system. The steel used is sourced from reliable sources and has undergone multiple quality tests to ensure that the strength, toughness and corrosion resistance reach high standards to ensure the stability and durability of the building.
