Waterproof membrane installation

Abstract

To prevent water from entering a room through a doorway E in the event of internal flooding due to an emergency such as a heavy rain, it is configured such that when a waterproof board 3 is swung from its stowed state to its waterproof posture, a portion of the waterproof board 3 closer to an inner wall G of a storage section 2 is prevented from protruding from the inner wall G of the storage section 2 toward the doorway E and to prevent damage to the doorway E.SOLUTION: A waterproof board 3 is supported by a support 16 for standing up from a stowed position with a first rotation shaft 11a and a second rotation shaft 12a as rotation centers. A movement range regulator 17 contacts a connecting piece 13 to regulate the rotation of the second rotation shaft 12a, and the waterproof board 3 rises with only the first rotation shaft 11a as the center of rotation. The end of the waterproof board 3 closer to an inner wall G on a doorway E side contacts the connecting piece 13 to restrict the rotation of the first rotation shaft 11a, and with this restriction, the waterproof board 3 stands up with only the second rotation shaft 12a as the center of rotation until the waterproof board 3 comes into contact with the doorway E.SELECTED DRAWING: Figure 3

Claims

1. A waterproof plate that swings and changes shape between a storage position in which it is laid down and stored in a storage compartment drilled into the ground or floor surface on the outdoor side of an entrance in a building, and a waterproof position in which it is upright and waterproofs the entrance. A first rotating shaft that pivotally supports the base end of the waterproof plate, A second rotating shaft is provided below the first rotating shaft and closer to the inner wall on the entrance side of the storage compartment, and pivotally supports the first rotating shaft relative to the inner wall of the storage compartment, A connecting piece that connects the first rotation axis and the second rotation axis, A support attached to the storage compartment, which supports the waterproof plate in its stored position, It comprises a movable range restricting body provided on the base end side of the support of the storage section, which restricts the rotation of the second rotation axis by contacting a connecting piece, The waterproof panel, supported by a support, rises from its stored position with the first and second rotation axes as its respective centers of rotation. A range-of-movement restricting body contacts a connecting piece to restrict the rotation of the second rotation axis, causing it to rise with only the first rotation axis as its center of rotation. The end of the waterproof panel near the inner wall on the entrance side then contacts the connecting piece to restrict the rotation of the first rotation axis, causing it to rise with only the second rotation axis as its center of rotation until it contacts the entrance. A waterproof plate device characterized by the following features.

2. The first and second rotation axes are connected by L-shaped blades. The waterproof plate device according to claim 1, characterized in that it is a waterproof plate device.

3. It comprises a frame body attached along the underside of the waterproof plate in the storage position, The support body supports the frame. A waterproof plate device according to claim 1 or 2, characterized in that it is a waterproof plate device according to claim 1 or 2.

4. The first and second axes of rotation are composed of the first and second hinges, The first hinge has one wing fixed to the underside of the waterproof plate, and the other wing fixed to one wing of the second hinge. The second hinge is fixed to the inner wall of the storage compartment with a predetermined gap between the other wing plates. The connecting piece is composed of the other wing of the fixed first hinge and one wing of the second hinge. A waterproof plate device according to claim 1 or 2, characterized in that it is a waterproof plate device according to claim 1 or 2.

5. It is installed between the storage compartment and the waterproof plate and includes a fixing body that secures the waterproof position of the waterproof plate. A waterproof plate device according to claim 1 or 2, characterized in that it is a waterproof plate device according to claim 1 or 2.

6. The fixing mechanism is a locking pedal that presses the waterproof plate in a waterproof position against the entrance / exit. The lock pedal rotates the waterproof plate around its first and second rotation axes, respectively, while the waterproof plate is upright and in contact with the entrance / exit area, thereby holding the waterproof plate pressed against the entrance / exit area and maintaining the waterproof position. The waterproof plate device according to claim 5, characterized in that it is a waterproof plate device.
