The invention discloses a
fire prevention,
corrosion prevention, heat preservation and decoration integrated H-shaped steel beam. The
fire prevention,
corrosion prevention, heat preservation and decoration integrated H-shaped steel beam comprises H-shaped steel, heat preservation filling
layers,
precast concrete and
steel bar nets arranged in the
precast concrete; the heat preservation filling
layers are arranged on the two sides of a web arranged in the middle of the H-shaped steel and located between an upper
flange plate and a lower
flange plate of the H-shaped steel; and the
precast concrete is arranged on the outer sides of the heat preservation filling
layers, the bottom of the precast concrete is closely attached to the bottom
flange plate of the H-shaped steel, the two side faces of the precast concrete are flush with the edges of the flange plates of the H-shaped steel, and the top of the precast concrete is closely attached to the top flange plate of the H-shaped steel. According to the
fire prevention,
corrosion prevention, heat preservation and decoration integrated H-shaped steel beam, through the integrated solution scheme, the H-shaped steel beam fire prevention,
corrosion prevention, decoration, sound insulation and heat preservation problems which are difficult to solve are solved, the anti-seismic superiority, the connecting reliability and the
structural safety of a steel structure technology and the fire prevention and
corrosion prevention property and the decoration property of an assembled type concrete technology are fully exerted, and the solution scheme is a very good solution scheme for the defects in an existing assembled type steel
structure system.
