Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof panel structure in a water shut-off device which is detachably attached to an entrance / exit of a building or a parking lot facility and which shuts off the entrance / exit in an emergency.

[0002]

2. Description of the Related Art A waterproof panel device is provided at a doorway,
Normally, the doors are allowed to pass freely, and in an emergency, such as when there is a risk of flooding due to heavy rain, etc., a waterproof panel is fitted into the panel frame provided on the floor surface and both sides of the doorway to block the doorway. Is.

The panel structure of this waterproof panel device is conventionally a combination of a front plate, a top plate, a bottom plate, left and right side plates, and a back plate, and a strength retaining layer having a honeycomb structure is sandwiched inside to increase the strength between them. The joints of are joined and integrated by welding or the like.

[0004]

As described above, in the conventional waterproof panel structure, the joint between the top plate, the bottom plate, and the left and right side plates is provided on the front plate on the side that comes into contact with water when water is stopped. However, since the strength of the joint is low and the airtightness is poor, there is a great risk that water will enter from the joint. When water penetrates from the front plate, the strength retaining layer in the inside has a honeycomb structure, and therefore the invading water spreads over the entire area without being blocked, and deterioration progresses, and eventually a strength problem occurs. Also, in some cases, water that has entered the strength retaining layer may leak from the joints of the back plates and enter the interior of the building.In this case,
It will completely lose its function as a waterproof panel. Further, the number of joints between the plates is large, resulting in poor work efficiency and increased cost.

The present invention solves the above-mentioned problems of the panel structure in the conventional waterproof panel device, and prevents the occurrence of water infiltration from the front plate as much as possible without providing a joint on the front plate on the side in contact with water. An object of the present invention is to provide a new waterproof panel structure that can be used.

[0006]

As means for achieving the above object, in the present invention, in an emergency, a waterproof panel is fitted into a panel frame provided on the floor surface and both sides of the doorway to close the doorway. A waterproof panel structure in a water stop device, which is composed of a front plate, a top plate, a bottom plate, and left and right side plates that are bent in four directions so as to reach the back side.
The back plate is brought into contact with the top plate, the bottom plate, and the left and right side plates extending to the back side, and the joints are joined and sealed to form a thin box-shaped body, and the inside of the box-shaped body is filled with polyurethane foam. , The waterproof packing mounting part is provided in the joint part except the top plate part side,
A waterproof panel structure is constructed in which a waterproof packing is fitted and fixed to the waterproof packing mounting portion.

Embodiments of the present invention will be described below with reference to the drawings. 1A is a front view showing an example of a waterproof panel structure according to the present invention, FIG. 1B is a plan view of the same, FIG. 1C is a rear view of the same, and FIG. It is also a side view. 2 is shown in FIG. 1 (b),
It is an A section expanded sectional view.

As shown in FIGS. 1 (a), 1 (b), 1 (c) and 1 (d) and FIG. 2, the waterproof panel 1 has a front plate 11,
The top plate 12, the bottom plate 13, and the left and right side plates 14, 15 are composed of a single steel plate that is bent in four directions so as to reach the back side, and the top plate 12, the bottom plate 13, and the left and right side plates 1 extending to the back side are formed.
The ends 4 and 15 (only the end 14a of the left side plate is shown in FIG. 2) are bent and cut into a hook shape. The back plate 16 has four ends 16a bent in a hook shape along the ends (14a, etc.) of the plates extending to the back side, and the top plate 12 extending to the back side.
It comes into contact with the bottom plate 13 and the left and right side plates 14, 15 to form a thin box-shaped body. Edges of each plate bent into a hook shape (14a, etc.)
The end portion 16a of the back plate and the end portion 16a of the back plate have a concave shape to form the waterproof packing attaching portion 3, and the joint portion 2 is joined by welding, rivets, screws or the like. The waterproof packing mounting portion 3 is fitted into the panel frame 5 provided on the floor surface and both sides of the doorway,
A waterproof packing 6 to be pressed against the panel frame 5 is fitted and fixed with a waterproof adhesive or the like. Top plate (1
Since the joint part 2 on the 2) side is not fitted in the panel frame 5,
No waterproof packing is applied, only waterproof caulking treatment is required.

A part of each of the plates constituting the box-like body, in this example the left side plate 14, is provided with a resin filling hole 7 in the center and air holes 8, 8 at positions vertically above the resin filling hole 7. is there. Further, air holes 8'and 8'are also formed at positions on the right side plate 15 facing the air holes 8 and 8. Foamed polyurethane is filled through the resin filling hole 7. At this time, air is released from the air holes 8, 8, 8 ', 8'and the filling is effectively performed. The foamed polyurethane is a polyurethane resin to which a known foaming agent is added, and after being filled, it is foamed by carbon dioxide gas generated during curing inside the box-shaped body, and the front plate 11, the top plate 12, the bottom plate 13, the left and right side plates 14 are formed. , 15 and the back plate 16 are spread to every corner and adhere to the inner surface of each plate to exhibit water resistance, which is preferable. Reference numeral 4 in FIG. 2 indicates a foamed polyurethane layer. The resin filling hole 7 and the air holes 8 and 8 are sealed after the filled resin foams.

A plurality of tightening handles 9 are attached to the back plate 16 at the left and right edges and the bottom edge except the top side. The tightening handle 9 is at the position of the phantom line in FIG. 1C when the waterproof panel 1 is fitted into the panel frame 5, and is rotated to the position of the solid line after fitting, as shown in FIG.
Tighten the waterproof panel 1 to the panel frame 5 as shown in
The waterproof packing 6 is pressed against the panel frame 5. This allows
The waterproof panel 1 and the panel frame 5 are in close contact with each other and completely prevent water from entering the building. Since the waterproof packing 6 is attached to the reverse side of the front plate 11 that comes into contact with water, when the waterproof panel 1 stops water, the water pressure acts so that the waterproof packing 6 closely contacts the panel frame 5. Reference numeral 20 is a handle attached to the top plate 12 so as to be easily carried when the waterproof panel 1 is fitted into or removed from the panel frame 5.

[0011]

As described above, the waterproof panel structure according to the present invention comprises a front plate, a top plate, a bottom plate, and left and right side plates that are bent in four directions to reach the back side. In addition, since the back plate is brought into contact with the top plate, the bottom plate, and the left and right side plates that extend to the back side, the joints are joined and sealed to form a thin box-shaped body. , Complete waterproofing can be achieved without any gaps in the joints between the top plate, the bottom plate, and the left and right side plates on the front plate that comes into contact with water when water is stopped. In addition, even if water intrudes into the waterproof panel for some reason, since it is filled with polyurethane foam inside the box-shaped body, unlike the conventional strength retaining layer having a honeycomb structure, it is a closed cell, Infiltration of water is blocked by the foamed polyurethane layer. Therefore, water does not permeate the entire area, and deterioration can be prevented. Since the polyurethane resin added with a foaming agent foams inside the box-shaped body, it spreads to every corner of the front plate, top plate, bottom plate, left and right side plates, and back plate, and adheres to the inner surface of each plate with high strength. And is lightweight because it is a foam.
