PURPOSE: A hinge member for a fire door and a frame member is provided to effectively increase the sealing effect and the soundproofing effect while removing interference by a wing part of the edge when closing a doorframe and the fire door, by improving the hinge member. CONSTITUTION: A hinge member(28) for a fire door and a frame member comprises a fire doorframe hinge shaft(30) and a fire door hinge hole(32). The fire doorframe hinge shaft has a support(34) protruded from a side of a fire doorframe(26), and forms a central axis(38) at a predetermined interval from the fire door and frame, in parallel with an edge reference line(36) of the edge of a wing part(22) of the fire door, on the support. The fire door hinge hole has a mounting part(42) mounted to the fire door with plural bolts(40); a support plate(44) formed in parallel with the front of the fire door; and the center of rotation(46) formed at a position of the central axis spaced from the fire door and frame, to be positioned in parallel with the edge reference line of the wing part of the fire door. |
