<p>PROBLEM TO BE SOLVED: To provide an air ventilation additional device capable of discharging air containing salt content accumulated within a top structure of a tower-like building or having high moisture by blowing air from a circumference of the top structure into it and capable of being added to the existing top structure of the tower-like building.SOLUTION: An air ventilation additional device 1 comprises an air ventilation additional device main body 2 constituted by a wind receiver part 3 for feeding air through an inlet 34 and an air blowing part 4 for feeding air fed into the wind receiver part 3 from an outlet 44; and a fixing mechanism 5 constituted by an upper fixing element 7 fixed to a top structure 102 by a connector element 10 and a lower fixing element 6 oscillatably attached to both the upper fixing element 7 and the air ventilation additional device main body 2 through connector elements 8, 9. The lower fixing element 6 is oscillated against the upper fixing element 7 around the connector element 9 and the air ventilation additional device main body 2 is oscillated against the lower fixing element 6 around the connector element 8, thereby it is possible to adjust an angle in which air fed from the inlet 34 of the wind receiver part 3 is fed out from a discharging port 44 of the air blowing part 4.</p> |
