PURPOSE:To simplify equipments erastically by making the titled damper have both functions of ventilation and fire prevention, by a method wherein, as for stopper plates set up on the insides of the top and bottom of a damper frame, a landing plate is provided on the side of the same in a stretched state, against which an end part of a blade is abutted, so that the tip of the blade is abutted against the landing plate. CONSTITUTION:A plurality of blades 2 is arranged on a damper frame 1 at equal intervals vertically by making the blade position in a horizontal direction, each of the blades 2 is fixed openably to the damper frame 1 and interlocked with the damper frame 1 synchronously. Then a stopper plate 17 is provided respectively on the insides of the top and bottom of the damper frame 1 in a setting state, and as for the stopper plate 17, a landing plate 19 is provided on the side of the same in a stretched state, against which an end part of the blade 2 is abutted, and on a position of the same where the tip of the blade 2 contacts with the landing plate 19. In consequence of this, as the titled device possesses an air conditioning damper function normally and a fire preventive function interrupting a fire at the time of the fire, equipments are simplified greatly, through which the titled device contributes to economy and energy saving together with the facilitation in management and drastic shortening of the installation period. |
