Reinforced steel beam heat insulation structure of fire-resistant window

The utility model relates to a reinforced steel beam heat insulation structure of a fire-resistant window, which is characterized in that a steel beam is connected on the outer side surfaces of an inner frame and an outer frame of a window frame, at least one rib is respectively arranged on the surfaces of the steel beam opposite to the inner frame and the outer frame, and the ribs are crimped on the outer side surfaces of the inner frame and the outer frame. According to the utility model, the rubber strips are sleeved at the end parts of the two sides of the steel beam, the fiberboard covers the outer side surface, and the steel beam is contacted with the surface opposite to the window frame through the convex edges, so that the contact area with the inner frame and the outer frame of the window frame is reduced, the outer side surface of the steel beam is subjected to heat insulation treatment, and the heat conduction at the part is reduced; the contact area of the fan steel beam and the bent steel beam an
