FIRE DOOR

PROBLEM TO BE SOLVED: To provide a fire door excellent in an outward appearance on an appearance, and capable of reducing even manufacturing cost.SOLUTION: In a double-hinged door composed of a master door 1 and a slave door 2, a master side outer recessed place 26 recessed in the thickness direction from an outside surface in its tip part and a master side inner recessed place 27 recessed in the thickness direction from an inside surface, are formed on a door end rail 11 of the master door 1, and a slave side outer recessed place 36 recessed in the thickness direction from the outside surface in its tip part and a slave side inner recessed place 37 recessed in the thickness direction from the inside surface, are formed on the door end rail 11 of the slave door 2, and a master side batten plate 44 for the master door is fixed to the master side outer recessed place 26, and also extends up to the slave side outer recessed place 36, and a slave side batten plate 54 for the slave door is fixed to the slave side inner recessed place 37, and also extends up to the master side inner recessed place 27. The master side batten plate 44 is stored in the master side outer recessed place 26 and the slave side outer recessed place 36, and the slave side batten plate 54 is similarly stored in the slave side inner recessed place 37 and the master side inner recessed place 27, so that rail aspects W1 and W2 can be set in the same dimension without protruding the batten plate to the outside.SELECTED DRAWING: Figure 1 【課題】外観上の見映えが良く製造コストも低くてすむ防火ドアを提供する。【解決手段】親扉１と子扉２とからなる両開きドアであって、親扉１の戸先框１１には、その先端部において外側表面から厚み方向に凹む親側外凹所２６と内側表面から厚み方向に凹む親側内凹所２７が形成され、子扉２の戸先框１１には、その先端部において、外側表面から厚み方向に凹む子側外凹所３６と内側表面から厚み方向に凹む子側内凹所３７が形成され、親扉用の親側目板４４が親側外凹所２６に固定され、かつ子側外凹所３６にまで延びており、子扉用の子側目板５４が子側内凹所３７に固定され、かつ親側内凹所２７にまで延びている。親側目板４４が親側外凹所２６と子側外凹所３６に収まり、同様に子側目板５４が子側内凹所３７と親側内凹所２７に収まっているので、目板が外側に出っ張らず框見付Ｗ１，Ｗ２を同一寸法にできる。【選択図】図１
