The invention discloses an upright fire ladder. A support seat is matched with an outer conical surface of the lower end of a support post body to be fixed through an inner cone hole in the middle; the outer conical surface of the support post body is matched with an inner conical surface of the inner core hole to be fixed; the inner cone hole is matched with the outer conical surface to be fixed; the attached inner conical surface and outer conical surface are deadly locked automatically through coordination of a lock groove in the inner conical surface and a lock terminal of a right-angle body; foot steps are fixedly arranged on the post body surface of the support post body; and ant-skid adhesive is glued on the foot steps, and is glued on the bottom of the support seat. The upright fire ladder is simple in structure and very convenient to assemble and use; the ladder does not need a tool in assembling and dismantling processes when used; after a tandem upright fire ladder is adopted, the problem that fire fighters vertically climb is solved; the fire ladder is fast to assemble in a vertical climbing process, convenient, safe, reliable and convenient to climb, and convenient to dismantle, pack and transport after being used; and the production cost and the use cost are reduced.
