Technical Field

The invention belongs to the technical field of steel structure construction, and in particular relates to an embedded component installation method suitable for a main steel structure.

Background Art

Steel structure embedded parts are commonly used in modern buildings, and their fixing method is crucial to the stability and safety of buildings. Traditionally, steel structure embedded parts are fixed by steel wire or steel nails after concrete pouring, but this method is prone to damage to the concrete surface and structural displacement. At the same time, due to the influence of vibration during the pouring process, the embedded parts will also be unstable, affecting the construction quality.
