The embodiment of the invention discloses an inserting-type strip-shaped buckle plate steel structure and an assembling method. The inserting-type strip-shaped buckle plate steel structure comprises strip-shaped buckle plate keels, light steel keels, light steel keel hanging pieces, hanging rods, strip-shaped buckle plates, hooks, bolts, along-edge strip plates, a ceiling structure body, strip-shaped buckle plate keel connectors, threaded groove holes, fixing studs and limiting lug seats. The assembling method of the inserting-type strip-shaped buckle plate steel structure comprises the stepsthat firstly, the strip-shaped buckle plate keels and the light steel keels are fixedly connected through the bolts, the light steel keel hanging pieces are fixed to the light steel keels, and the hanging rods are mounted on the light steel keel hanging pieces; then the along-edge strip plates on the two sides of the strip-shaped buckle plates are carried on the hooks of the strip-shaped buckle plate keels; and finally, the arranged fixing studs are used for penetrating through the limiting lug seats to extend to the strip-shaped buckle plates to be connected with the threaded groove holes, and finally, the fixing studs are fastened.
