The present invention relates to a door lock housing of a fire door and, more specifically, relates to a door lock housing capable of preventing the condensation of a fire door through the door lock housing by preventing thermal conduction between front and rear plates, forming the housing, through a cylinder bar and a door lock, and moreover, obtaining housings of various standards by only controlling the height of a pillar. The door lock housing comprises: front and rear plates placed at a predetermined distance from each other and in parallel with each other; an insulating plate having a predetermined thickness and fixed to the inner surface of each of the front and rear plates; a cylinder bar placed in front of the front and rear plates to be fixed; short pillars placed on both outer surfaces of the cylinder bar and between the inner surfaces of the front and second plates; and a pillar vertically fixed between rear sides of the front and rear plates. |
