Abstract
In order to recheck the safety of the construction of prefabricated box-type light steel structure house, the structural safety checking calculation is carried out for box connection stress, column bottom stress, anti-wind load design and anti-overturning design. The elastic connection is used for node simulation, and the on-site tensile test is carried out to check the reliability of the model. Based on the connection mode between box column and corner fittings, the frame reinforcement construction technology of prefabricated box-type light steel structure house is studied. A rectangular-ambulatory-plane steel plate is welded at the outer edge of the corner fittings, to reinforce frame structure, and improve the service life and comfort of prefabricated box-type light steel structure house.
