Light steel structure plant wind-resisting column and roof beam connection structure

The utility model belongs to the field of design of building structures, and particularly relates to a light steel structure plant wind-resisting column and roof beam connection structure. A node connection part is fixedly connected to the lower flange of a roof beam, and a longitudinal long round bolt hole is formed in the node connection part, and the node connection part is connected with a wind-resisting column web through the long round bolt hole with a bolt. According to the light steel structure plant wind-resisting column and roof beam connection structure, the requirement for vertically and free moving of the roof beam through connection of the light steel structure plant wind-resisting column and the roof beam and the use requirement for well transmitting horizontal loads borne by a wind-resistant column in the horizontal direction of the wind-resisting column and the roof beam can be conveniently met.
