Problem to be solved: to provide a building structure having a bird protection function and a fire extinguishing function capable of suitably using a bubble extinguishing agent having a low foaming factor in the construction of a roof having a roof such as a three-dimensional parking lot.A bird proof net 102 having a network structure provided substantially above the fire prevention area on the floor in a building having a roofAt least one bubble aqueous solution head 104 disposed above the bird protection netFoam quenching agent storage tank for supplying a bubble extinguishing agent to the bubble aqueous solution headAndThe bird protection net is made of fire retardant resin.The network structure has a substantially square opening and one side of the aperture is 10 toThe foaming factor of the bubble extinguishing agent released from the bubble aqueous solution head is less than 5 times.Diagram【課題】立体駐車場等の屋根を有する建造物において、防鳥ネットの設置下で低発泡倍率の泡消火薬剤を好適に使用できる防鳥・消火機能付き建造物構造を提供する。【解決手段】屋根を有する建造物内において床上の防火区域の略上方に設けられた網目構造を有する防鳥ネット１０２と、防鳥ネットの上方に設けられた少なくとも１つの泡水溶液ヘッド１０４と、泡水溶液ヘッドに泡消火薬剤を供給するための泡消火薬剤貯蔵槽と、を具備し、防鳥ネットが難燃性樹脂で構成されており、網目構造が略正方形の開口を有し開口の一辺が１０～５０ｍｍであり、泡水溶液ヘッドから放出される泡消火薬剤の発泡倍率が５倍未満である。【選択図】図６
