<p>PROBLEM TO BE SOLVED: To provide a ventilation structure which can be easily constructed with little changes in a skeleton structure of a spandrel wall and a shape of a head board.SOLUTION: A ventilation structure comprises: first and second outer wall materials 23 and 24; a through-member 20 arranged between the outer wall materials in the vicinity of an upper end; a top end material 25 which is fixed to an upper part of the through-member, and continuously covers a portion from an upper part of the first outer wall material up to an upper part of the second outer wall material; and ventilation hardware 26 which is arranged between a side end part near the first outer wall material of the top end material and an upper end of the first outer wall material. The ventilation hardware has: a first horizontal face fixed to an upper face of the top end material, a first vertical face which is curved downwardly from a side end of the first horizontal face, downwardly extends from a lower face of the top end material while abutting on or approximating a side end of the top end material, is constituted without substantially having a step between an external surface of the first outer wall material and itself, and has a ventilation hole; and a second horizontal face which is curved from a lower end of the first vertical face, extends to the though-member side, is connected to an upper end of the first outer wall material located at a lower part, and has a ventilation hole at a portion which is closer to the through-member side than the connecting part.</p> |
