開閉できない。また、鉄の熱伝導率が高いため火災時に
扉が熱くなって開閉ができず避難障害となる場合も生ず
る。さらに開閉時の金属音が大きい。デザイン性に欠け
る。錆などの耐久性の問題がある。The fire doors of apartments, office buildings, and public / commercial buildings are generally made of metal materials, but the doors themselves are heavy, and large doors can be easily opened and closed by women and children. Can not. In addition, since iron has a high thermal conductivity, the door may become hot during a fire and the door cannot be opened or closed, which may cause an evacuation obstacle. Furthermore, the metallic noise when opening and closing is loud. Lack of design. There is a problem of durability such as rust.
【０００６】この発明は上記の問題点に着目しなされた

クリートは耐酸性，耐蝕性が優れているため耐久性が向
上し、不燃材料であるため耐火性に富み、遮音性，振動
減衰性が良いため音に関する環境問題を緩和できる。In this concrete door, the fiber-reinforced concrete as the base material exhibits high bending strength, so that the door can be made large in size and thinned to be lightweight. Further, the fiber reinforced concrete is excellent in acid resistance and corrosion resistance, so that the durability is improved. Since it is a non-combustible material, it is rich in fire resistance, and good in sound insulation and vibration damping, so that environmental problems related to sound can be mitigated.
