WATERTIGHT SHIELDING DEVICE, OR ANTI-THEFT DEVICE FOR WATERPROOF DOOR
PROBLEM TO BE SOLVED: To solve the problems with conventional technologies of a general structure utilizing pressing force of a cylinder or pressing by a flash board for a waterproof door that adhesiveness and fastening on a mullion is not sufficient, and problems with other technologies described in literatures of a structure that does not press a packing and therefore does not offer water-tightness effect, although tightening has been intensified sequentially using different distances of eccentricity of an eccentric cam.SOLUTION: A waterproof door of the present invention is installed for waterproofing a subway, an underground structure for a subway, and an above-ground structure. An eccentric cam is provided on a side of a mullion at an entrance/exit exposed to water pressure, the eccentric cam having a cam surface biased toward a side of the mullion not exposed to water pressure. The eccentric cam is pressed against a side of the waterproof door exposed to water pressure, at the same time pressing a watertight elastic body on a side of the waterproof door not exposed to water pressure. Wedge tightening is attempted between one wedge disposed on a side of a waterproof door body exposed to water pressure and the other wedge on the cam surface of the eccentric cam. The eccentric cam and the watertight elastic body enable the waterproof door to adhere to and be tightened on the mullion.SELECTED DRAWING: Figure 1
【課題】従来技術では、シリンダーによる押圧とか、又は角落しによる押込みによる一般的な構造であり、防水扉を、方立てに密着、かつ緊締に関して、十分とは考えられない。その他の文献技術において、偏芯カムの偏芯距離が異なることを利用し、順次、締付けを強化する。しかしながら、同時にパッキンを押圧する構造でなく、水密の効果が期待できないと考えられる。【解決手段】本発明は、地下鉄、地下室の地下構造物、地上構造物の防水用として設置される防水扉であり、出入口の方立ての水圧対峙側に、反水圧対峙側に偏倚したカム面を有する偏芯カムを設け、偏芯カムは、防水扉の水圧対峙側に圧接し、同時に、防水扉の反水圧対峙側の水密弾性体を押圧し、防水扉本体の水圧対峙側に設けた一方の楔と、偏芯カムのカム面の他方の楔との間に楔緊締を図る。偏芯カム・水密弾性体により、防水扉を、方立てに密着、かつ緊締できる。【選択図】 図１
