【発明の属する技術分野】本発明は建築物、工作物等への浸水を防ぐ為、生活上で求められるものです。

【従来の技術】浮力式水防板の前面に水防板が浮力で浮上する為の注水口にあたるグレーチング蓋を設けた一次槽を設けてある。又、水防板が侵入水がわずかで浮上もわずかの場合にはつまづく危険がある。
【０００３】
【発明が解決しようとする課題】浮力による水防板を浮上させる為の侵入水を水防板の格納槽に注水する為の注水口が普段の通行面にあるのが従来のタイプである為に機能的及び美観的に改善が設置場所により求められている。又、水防板の浮上がわずかの場合にはつまづく危険がある。
【０００４】
【課題を解決する為の手段】請求項１で示した構成により、両側の壁又は袖壁下部に設けた注水口によれば、通行面にはグレーチングや格子蓋が不要になり、通行上や美観上の改善がはかられる。壁又は袖壁下部に設けたルーバー付注水口の下端の枠寸法の調整により一定量以上の侵入水が浸水してこなけば侵入水は水防板の格納槽には入らない。通行部分のスロープの高い部分は侵入水を注水口に先に誘導する為に必要な注水口下端のレベルより高い。水防板の蓋にあたる部分の前後にわずかな浮上の場合に気づかずにつまづかぬようにフラップを取り付ける。
【０００５】
【発明の実施の形態】侵入水の浮力で浮上する水防板の蓋のレベル迄スロープで上がる。スロープの下のレベルから上のレベルの間の両側の袖壁等の下端に下枠を多少上げて注水口をガラリを取り付けて設置する。水防板の蓋部分にはわずかな浮上の際に歩行者がつまづかぬようフラップを設ける。注水口のガラリは環境により自由に選択可。
【０００６】
【発明の効果】地下鉄や地下街等への歩道からの出入り口は非常に歩行上危険な場所である為に浸水を防ぐ為の格子蓋やグレーチング類の上は歩きにくく、美観上も好ましく無く、避けたい要望があります。又、豪雨等の際の浸入水を防ぐには浸入水により自動的に浮上する水防板でないと対処が遅れ危険をいち早く避ける事は出来ません。
しかし、浮上式水防板は浸入水を受け入れ、その浮力を利用して水防板を立上げる為に通行面にグレーチングや格子蓋等の注水口を従来は設けねばなりませんでしたが、本発明により普段の通行面には格子蓋やグレーチングは必要ありません。浮上式水防板には両側に壁や袖壁が必要である為にその下部に注水口を設ければ問題は解決します。水防板の蓋の部分にフラップをつければわずかな浮上時のつまづきが防止出来ます。

[Technical field to which the present invention pertains] The present invention is required in daily life to prevent inundation of buildings, structures and the like.

2. Description of the Related Art A primary tank provided with a grating lid serving as a water inlet for floating a float by buoyancy is provided in front of a buoyancy type flood shield. In addition, there is a risk of tripping when the water intrusion of the water shield plate is small and the water floats only slightly.
[0003]
The conventional type has a water inlet for injecting intrusion water into the storage tank of the water shield to float the water shield due to buoyancy, which is a conventional type. Improvements in terms of design and aesthetics are required depending on the installation location. In addition, there is a risk of tripping when the floating board rises slightly.
[0004]
According to the structure shown in claim 1, according to the water inlet provided in the lower wall of the side wall or the sleeve wall, grating and a grid cover are not required on the traffic surface. Aesthetic improvement is achieved. If the intruding water of a certain amount or more is flooded by adjusting the frame size of the lower end of the louver-equipped water inlet provided at the lower part of the wall or the sleeve wall, the intruding water does not enter the storage tank of the flood control board. The high slope portion of the traffic section is higher than the level at the bottom of the water inlet, which is necessary to guide the intruding water to the water inlet first. Attach the flap so that it does not trip over without being noticed in the case of slight floating before and after the part corresponding to the lid of the water shield.
[0005]
DETAILED DESCRIPTION OF THE INVENTION The slope rises to the level of the lid of the flood board floating by the buoyancy of the intruding water. The lower frame is slightly raised at the lower end of the sleeve wall etc. on both sides between the lower level and the upper level of the slope, and the water inlet is installed with a gull. The flap is provided with a flap on the lid to prevent pedestrians from tripping during a slight ascent. The water inlet can be freely selected according to the environment.
[0006]
The entrance from the sidewalk to the subway, underground mall, etc. is a very dangerous place for walking, so it is difficult to walk on the lattice lid or gratings to prevent inundation, and it is not preferable from the viewpoint of aesthetics. I have a request. In addition, in order to prevent water intrusion in the event of heavy rain, it is not possible to avoid danger as soon as possible unless measures are taken to prevent the waterboard from automatically rising due to water intrusion.
However, floating type water shields have conventionally had to provide water inlets, such as gratings and lattice lids, on the traffic surface in order to receive infiltration water and use the buoyancy to start the water shields, but according to the present invention No grid lids or gratings are required on normal traffic surfaces. Floating barriers need walls and sleeves on both sides, so providing a water inlet at the bottom will solve the problem. If you attach a flap to the lid of the water shield, you can prevent slight stumbling at the time of ascent.
