SEAT PLATE PRESSING TOOL FOR SHUTTER DEVICE AND ITS PRESSING DEVICE
To provide a seat plate pressing tool for a shutter device and its pressing device that can prevent a seat plate from bending and deforming significantly in the shutter curtain thickness direction and lifting up due to, for example, wind pressure, without any machining work on a bottom surface forming member that forms the bottom surface of a space closed by the shutter curtain when fully closed.SOLUTION: A seat plate pressing tool 30 is positioned over an underside forming member, such as a floor member 10, that forms the underside of a space closed by the shutter curtain 2 when it is fully closed. The seat plate pressing tool 30 has a contact portion 31 which the seat plate 4 contacts from above and an extension portion 32 that extends outward from this contact portion in the direction of the thickness of the shutter curtain. A top surface 31A of the contact portion and a top surface 32A of the extention portion are continuous, and the height dimension of the top surface 32A of the extention portion on which the seat plate 4 rides when flexed in the thickness direction of the shutter curtain gradually increases as the extension portion 32 extends outward in the thickness direction of the shutter curtain.SELECTED DRAWING: Figure 6
【課題】全閉時のシャッターカーテンで閉じられる空間の下面を形成する下面形成部材に何らの加工作業を行うことなく、風圧等により座板がシャッターカーテンの厚さ方向に大きく撓み変形して浮き上がることを防止できるシャッター装置の座板押え具及びその押え装置を提供すること。【解決手段】座板押え具３０は、全閉となったときのシャッターカーテン２で閉じられる空間の下面を形成している床部材１０等の下面形成部材の上に配置され、座板押え具３０は、座板４が上から当接する当接部３１と、この当接部からシャッターカーテンの厚さ方向の外側へ延びている延出部３２とを有し、当接部の上面３１Ａと延出部の上面３２Ａとが連続しているとともに、シャッターカーテンの厚さ方向に撓み変形したときの座板４が乗り上げる延出部の上面３２Ａの高さ寸法は、延出部３２がシャッターカーテンの厚さ方向の外側へ延びるにしたがって次第に大きくなっている。【選択図】図６
