BUILDING STRUCTURE WITH BIRD PREVENTION/FIRE EXTINGUISHING FUNCTION
PROBLEM TO BE SOLVED: To provide a building structure with bird prevention/fire extinguishing functions which can reliably extinguish fire by discharging foam fire-extinguishing agents to a predetermined area without harmful influence to the fire extinguishing function while providing a bird prevention net for a building with a roof over a multi-storey parking space and like.SOLUTION: A building structure with bird prevention/fire extinguishing functions is provided with; a bird prevention net in a mesh type structure arranged generally upward over a fire prevention area on a floor in a building structure with a roof; at least one closed-type head for foam arranged above the bird prevention net; and a storage tank of foam fire extinguishing agents to supply foam fire extinguishing agents to the closed-type head for foam, wherein the bird prevention net composed of fire retardant resign, the mesh type structure is provided with openings generally shaped in a square with each edge of the openings 20 to 50 mm in length, and an expansion ratio of the foam fire extinguishing agents discharged form the closed-type head for foam is 5 to 10 times and 25% reduction time thereof is one minuit or more.SELECTED DRAWING: Figure 1
【課題】立体駐車場等の屋根を有する建造物において、防鳥ネットを具備しながらも消火機能を損なわずに所定区域に泡消火薬剤を放出して確実に消火可能な防鳥・消火機能付き建造物構造を提供すること。【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と、前記防鳥ネットの上方に設けられた少なくとも１つの閉鎖型泡ヘッドと、前記閉鎖型泡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、前記防鳥ネットが難燃性樹脂で構成されており、前記網目構造が略正方形の開口を有し前記開口の一辺が２０〜５０ｍｍであり、前記閉鎖型泡ヘッドから放出される前記泡消火薬剤の発泡倍率が５〜１０倍であり２５％還元時間が１分間以上であること、を特徴とする防鳥・消火機能付き建造物構造。【選択図】図１
