However, the structure of this water stop door is complicated, and if it is not always maintained, it may not be able to be blocked in an emergency due to a failure. Furthermore, if the water stop panel does not join accurately at the center, water will enter from the joint. There is also a risk.

  The present invention has been made in view of such a point, and an object of the present invention is to use a water stopping plate that can be easily operated by one person in an emergency, and can reliably stop water without requiring normal maintenance, and the same. The purpose is to provide a water stop structure.

In order to achieve the above object, the waterstop plate according to the invention described in claim 1 is a rectangular fiber-resin composite made of resin and fiber, and the vertical direction center line is the vertical direction of the main fibers. It is characterized by being curved so as to be the most protruding portion.

  The waterstop plate according to the invention described in claim 2 is characterized in that 20 to 50% of the fibers oriented in the vertical direction according to claim 1 are oriented in the horizontal direction.

  In the waterstop plate according to the invention described in claim 3, the fiber according to claim 1 or 2 is formed by laminating a plurality of layers of sheets in which fibers are oriented in one direction.

  A waterstop plate according to a fourth aspect of the present invention is characterized in that at least a part of the fibers according to any one of the first to third aspects is a carbon fiber.

  The water stop structure using the water stop plate according to the invention of claim 5 is the water stop plate according to any one of claims 1 to 4 in the direction of water inflow from the left and right ends of the opening. The both ends of the water stop plate are fixed to the left and right ends of the opening through a pair of connectors in a state of being curved in a convex shape.

  According to a sixth aspect of the present invention, there is provided the water stop structure according to the fifth aspect of the present invention, wherein the pair of couplers has a fixing groove that is inclined forward from the horizontal position so that each of the connecting tools is symmetrical. Each end of the water stop plate is inserted and fixed.

The water stop plate of the present invention is composed of a rectangular fiber resin composite in which the orientation direction of the main fibers is the vertical direction and fixed with resin, so that it easily deforms against the force in the vertical direction not directly applied to the fibers, Since it is difficult to be deformed by a horizontal force applied directly, it can be easily bent so that the center line in the vertical direction becomes the most protruding portion. In addition, since the water stop plate can be bent freely, it is usually stored as a flat plate and can be used by bending it in an emergency, so it can be stored and saves space, preventing damage and deformation of the plate in a curved state. it can.

In the invention of claim 2, 20 to 50% of the fibers oriented in the vertical direction according to the invention of claim 1 are oriented in the horizontal direction, so that the effect obtained in claim 1 is maintained while maintaining the effect in the horizontal direction. A certain degree of strength can be obtained against force. Further, by adjusting the fiber orientation ratio between 20% and 50%, it is possible to obtain a uniform balance between formability and the entire waterstop.

In the invention of claim 3, as the fiber oriented in one direction of the vertical direction or the horizontal direction used for the fiber resin composite, a plurality of sheets in which the fibers are oriented in one direction are laminated, so the fiber orientation ratio Can be easily adjusted by the orientation direction and the number of sheets.

In the invention of claim 4, by using at least a part of the fibers as carbon fibers, a water stop plate that is lighter and higher in strength and superior in dimensional stability than a glass fiber or the like can be obtained although the cost is slightly increased.

In the invention of claim 5, with the water stop plate curved in a convex shape from the left and right ends of the opening toward the inflow direction of water, the both ends of the water stop plate are connected to the opening through a pair of connectors. By fixing to the left and right ends, a part of the water flow that hits the water stop plate flows laterally along the water stop plate, the water pressure is lowered, and it can withstand a larger amount of water.

In the invention of claim 6, the pair of couplers each have a fixing groove that is inclined forward from the horizontal position so as to be symmetrical, and each end of the water stop plate is inserted and fixed in the fixing groove. Thus, the water stop plate can be curved in an arch shape toward the water inflow direction, and the effect obtained in claim 5 can be easily obtained.

It is a top view which shows the fixed part of a water stop plate and a connection tool in detail.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of the embodiments is merely illustrative in nature and is not intended to limit the present invention, its application, or its use at all.

FIG. 1 is a perspective view showing a water stop plate 1 according to the present invention. The water stop plate 1 is a fiber resin composite such as FRP or CFRP in which fibers are oriented in one direction and fixed with a resin. The orientation direction of the fiber is the orientation 1a in the vertical direction. As a result, the water stop plate is difficult to bend in the direction in which the fibers are orthogonal (bent) and is easy to bend in the fiber direction. If this property is utilized, the water stop plate 1 can be easily curved by hand with the center line 1c as the most protruding portion of the rectangular molded body 1.

In the conventional water stop plate, when a curved one is necessary, it is molded using a mold material in advance. However, it is necessary to use an expensive mold material, and it takes time and effort to mold. In addition, the curved waterstop may take up space for storage or may become unusable due to deformation or breakage during storage, but the waterstop using the molded body of the present invention must be molded in advance. Therefore, it is possible to easily obtain a water stop plate that is curved on the spot according to the size of the site.

On the other hand, the fact that it is easy to mold means that it is easily deformed by water pressure. Therefore, it is easy to be deformed when water pressure is applied to a resin portion without fibers, but the fiber 1a oriented in one direction (vertical direction). It is possible to cope with water pressure from various directions by setting a part of the fiber to a direction orthogonal to each other (fiber 1b oriented in the horizontal direction). The ratio of the orientation of the fibers in both the width and length directions must balance the ease of molding and the strength, but 20 to 50% of the fibers 1a oriented in the vertical direction and the fibers 1b oriented in the horizontal direction It is preferable to do this. In FIG. 1, the fibers are represented by solid lines 1a and 1b for the sake of convenience. Also, the number is different from the actual one, and the structure is schematically shown for easy understanding.

The fiber resin composite (specific gravity 1.5 to 2.0) used for the waterstop plate 1 is compared with iron (specific gravity 7.8) and light weight aluminum (specific gravity 2.7) used in the conventional waterstop plate. It is lightweight and can work alone.
Glass fiber or the like can be used as the fiber, but a lighter and stronger fiber-resin composite, that is, the waterstop plate 1 can be obtained by using high-strength carbon fiber.

As the fiber used for the fiber resin composite, a plurality of sheets in which various reinforcing fibers such as glass fiber and carbon fiber are oriented in one direction even with short fibers or long fibers can be laminated. Accordingly, the orientation ratio of the fibers in the vertical direction and the horizontal direction can be easily adjusted in order to balance the ease of forming and the strength. In addition, the type of fiber sheet to be laminated is, for example, a carbon fiber sheet in which the front and back layers are oriented in the vertical direction, and the core layer is appropriately combined with a glass fiber sheet and a multi-layer fiber orientation, thereby achieving a balance of strength and cost. A water stop plate can be obtained.

Since ordinary FRP can flexibly adapt to various shapes and is excellent in strength, a reinforcing base made of fiber resin composite is pre-shaped in a mold, and the resin is manually impregnated with a brush or roller and defoamed. While hand lay-up molding is used to laminate to a predetermined thickness,
Since CFRP using carbon fiber is light in weight, it often clings to brushes, etc., and does not become a product. The process is expensive because it takes a long time.

Therefore, this molding method is a method of applying without tying up to the tool by hand lay-up. The method is performed in the following order.
1. Prepare a mesh material such as insect repellent, and apply the covering resin before applying the resin to the carbon material.
2. Air bubbles contained in the unpacking roller to the outside
3. Repeat steps 1 and 2 as many times as necessary.
4). Cover the surface with a polyester film,
5. Similar to the FRP molding, a necessary thickness spacer is arranged to bend the metal plate, decapsulate from the center to the end, and wait for curing.

Next, a method of using the water stop plate body 11 shown in FIG. 1 as the water stop plate 1 shown in FIG. 2 will be described. As described above, the flat water-stop plate body 11 can be bent in the direction along the fiber, but is usually stored in a flat plate shape. When used, the horizontal packing 12 is provided over the entire length in the horizontal direction of the upper and lower ends. The horizontal packing 12 at the lower end functions as a waterproof material for the floor portion, and the horizontal packing 12 at the upper end functions as a waterproof material for stacking the water blocking plates 1 in the vertical direction. Accordingly, when the water stop plate 1 is used alone, only one of the lower end sides is sufficient.

The vertical packing 13 in the vertical direction is fixed over the entire length of the right and left end portions of the water stop plate body 11 so that water does not enter from the connector 2 when the water stop plate 1 is fixed to the connector 2 described later. . Details of the mounting structure are shown in FIG. Although the material of these packings is not specifically limited, For example, various rubbers (SBR, EPDM, NBR, silicone), thermoplastic elastomers, and the like that are generally used can be used. In addition, the size and shape are not particularly limited as long as the water can be stopped. However, if the groove and the like are provided so as to be fitted into the water stopping plate, they can be removed during storage or deterioration.

Next, a method for attaching the water stop plate 1 to the entrance / exit where the water stop plate 1 is required will be described. FIG. 4 is a perspective view of the underground entrance and exit in a normal state, and FIG. 5 is a perspective view when a water stop plate is installed at the same underground entrance and exit. A pair of connectors 2 are firmly fixed in advance with screws or the like in accordance with the water stop plate installation heights at the left and right ends of the opening of the underground entrance.

FIG. 6 is a perspective view showing the connector 2, the installation part 22 at the entrance / exit, the cover part 23 for pressing the water stop plate, and a right angle projecting from the installation part and abutting the left and right openings to stabilize the connector 2. A vertical fixing piece 24 that can be fixed in place, a water-stop projection 26 that has a waterproof function when the vertical packing 13 is in close contact, a fixing groove 21 that is formed from the cover portion and the water-stop projection, a screw or the like The fixing hole portion 27 is fixed to the entrance / exit, and the screw hole 25 is formed by cutting a tap for screwing a screw for fixing the water stop plate 1 to the connector 2.

  As shown in FIGS. 7 and 8, the connector 2 is formed by the cover portion 23 protruding forward so that the fixing groove 21 for fixing the water stop plate 1 is inclined forward from the horizontal position, and a pair of The coupler 2 is firmly fixed to the left and right ends A of the opening by a fixture 4 such as a concrete nail so that each of the couplers 2 is symmetrical. And after curving the water stop board 1 so that the center part 1c may become convex ahead, the vertical side packing 13 is crushed by inserting along the cover part 23, and it is by the repulsive force by the elasticity The water stop plate 1 is crimped to the back surface of the cover portion 23 and has a waterproof function. At this time, the water stop plate 1 can be fixed in a convexly curved state from the left and right connectors 2 forward (toward the water inflow direction), and the screw 3 is inserted into the screw hole 25 as indicated by an arrow. By screwing and pushing the water stop plate 1 with the tip of the screw 3, the adhesiveness between the vertical packing 13 and the connector 2 is further enhanced and fixed so as not to move.

The horizontal packing 12 at the lower end between the water stop plate 1 and the floor can prevent water from entering even if there is some unevenness on the floor surface. As shown in FIG. 9, when the upper horizontal packing 12 is installed as a stack of the waterstop plates 1 on the left and right ends B of the opening, as shown in FIG. Provide to prevent water from entering between the water plates. Even when the intrusion height is increased or the opening width is large, by reducing the height of one water stop plate, the workability in an emergency is not lowered without increasing the weight per sheet. .

The water stop plate installed in this way is curved in a convex shape from the left and right openings toward the inflow direction of water, so that part of the water flow that hits the water stop plate is laterally along the water stop plate. The flowing water pressure decreases and can withstand a larger amount of water.

The present invention can be easily bent by a lightweight water stop plate, so that even one person can work in an emergency and can easily obtain a water stop structure. Therefore, the present invention is extremely useful and has high industrial applicability.
