The top of the frame beam is also equipped with several embedded steel plates corresponding to the columns, and each embedded steel plate is securely connected to embedded reinforcing bars. The bottom surface of the columns is provided with a reserved grouting sleeve for fitting the embedded reinforcing bars. This prefabricated connecting corridor structure with frame beams and columns overcomes the defects of existing technologies using cast-in-place construction methods. It enables factory prefabrication and on-site layer-by-layer assembly, resulting in simple construction, short cycle time, high assembly efficiency, low construction cost, environmental friendliness, and safety and reliability. It also solves the problems associated with using expansion bolts to securely connect steel structure connecting corridors to buildings. It is widely applicable to outdoor elevator connecting corridors.
