AIR VENTILATION ADDITIONAL DEVICE AT THE TOP OF TOWER-LIKE BUILDING

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. 【課題】搭状建造物の頂部構造体内部に籠もった塩分を有し或いは湿度の高い空気を、頂部構造体の周囲から内部に空気を送り込むことで排出でき、既存の搭状建造物の頂部構造体に付加することが可能な換気用付加装置を提供する。【解決手段】換気用付加装置１は、空気を導入口３４から導入する受風部３と、受風部３に導入された空気を送出口４４から送出する送風部４とで構成される換気用付加装置本体２と、頂部構造体１０２に連結具１０にて取り付けられる上側取付具７と、上側取付具７及び換気用付加装置本体２の双方に連結具８、９を介して揺動可能に取り付けられている下側取付具６とにより構成される取付機構５とを備え、下側取付具６を上側取付具７に対し連結具９を中心として揺動させ、換気用付加装置本体２を下側取付具６に対し連結具８を中心として揺動させることにより、受風部３の導入口３４から導入した空気を送風部４の送出口４４から送出させる角度を調整できる。【選択図】図６
