Embedding Technology Of Steel Structure Anchor Bolts

Embedding technology of steel structure anchor bolts is a construction process in which anchor bolts are pre-fixed inside concrete during foundation construction. It is widely applied in building foundation works, especially for the foundation construction of steel structure buildings.

The main procedures of embedding construction are as follows:

Design and Planning: Before the embedding of anchor bolts, complete design planning to confirm parameters such as bolt position, quantity and specification size. All parameters shall be determined according to structural calculation results and design drawings of the building.

Installation of Embedded Anchor Bolts: Prior to concrete pouring, fix the anchor bolts in the foundation in accordance with design requirements. The common practice is to fabricate special positioning brackets to secure anchor bolts, ensuring their position, elevation and verticality meet specification requirements.

Concrete Pouring: After the anchor bolts are positioned and fixed, carry out concrete pouring. The concrete wraps the bolts to form a stable foundation anchoring system. Avoid disturbing the bolts by vibration during pouring to prevent displacement and deflection.

Bolt Connection and Fixation: After the concrete reaches the designed strength, connect and fix the anchor bolts with the base of steel columns using nuts and matching washers. A reliable foundation anchoring structure is formed to provide support for subsequent steel structure installation.

Advantages of the embedding technology for steel structure anchor bolts: it improves construction efficiency, enhances the overall stability and reliability of the structure, reduces on-site welding work and lowers the construction difficulty and safety risks caused by welding. This process is increasingly widely used in steel structure buildings and has been recognized and promoted in the engineering industry.
