Description

The present invention relates to a waterstop plate that is curved in the inflow direction of water and fixed to the opening, and a method of mounting the waterstop plate using the waterstop plate.

In recent years, inundation has occurred in low land due to heavy rains of guerrillas and huge typhoons, and especially when water infiltrates from entrances and exits of underground malls, underground parking lots, subways, etc., urban functions are paralyzed and serious damage occurs.

In order to prevent this, various water stop devices are used to block the ingress of water at the entrance and exit, but conventionally, a plate is attached to a frame-shaped frame as a water stop plate, and a thick panel is used in an emergency. It was installed by fixing it to the doorway, pulling out what was stored with a rail, opening and closing it with a hinge hinge, and so on.

For example, in Patent Document 1, a pillar having grooves on both sides of the entrance of a building is erected, a waterproof plate provided with elastic waterproof rubber is fitted in the groove, and the waterproof plate is pressed against the pillar to allow water to enter. According to this, the waterproof plate is a hollow structure made of aluminum and the inside is reinforced with a stainless steel plate. Is necessary, and it is difficult to respond promptly in an emergency.

In Patent Document 2, water blocking panels are connected to the side walls at both ends of the opening by connecting members, and are usually housed in the side wall portion. In an emergency, the water blocking panel is pulled out and fixed at the center to shield the opening. Can be obtained. According to this, there is an advantage that the problem of Patent Document 1 is solved and even one person can easily work.

However, the structure of this water stop door is complicated, and if maintenance is not always performed, it may not be possible to shield in an emergency due to a failure. Furthermore, if the water stop panel is not joined accurately in the center, water will enter from the joint. There is also a risk of doing so.

Patent Document 3 solves these problems and allows easy installation, but it is necessary to attach a connecting tool in advance to the mounting corners on the left and right of the opening, except in an emergency where a waterstop is not required. In the case of, the connector is fixed to the opening and it becomes an obstacle and looks bad. For example, in the case of an entrance where most of the opening is made of glass and sash, such as a store such as a convenience store, it is installed. It becomes impossible in itself.

Japanese Unexamined Patent Publication No. 2001-987792 JP-A-2002-30867 JP-A-2017-128902

The present invention has been made in view of these points, and an object of the present invention is that even one person can easily perform work in an emergency, water can be reliably stopped without the need for usual maintenance, and it is necessary to attach metal fittings in advance. The purpose is to provide a water stop plate that can be fixed anywhere without a water stop and a water stop structure using the water stop plate.

In order to achieve the above object, the water stop plate according to claim 1 is a water stop plate fixed to the mounting corners on the left and right of the opening, and the water stop plate is a flat plate-shaped water stop plate having elasticity. It consists of a main body and fittings provided at both ends of the main body of the water stop plate, and the fittings are locked along the mounting corners . It consists of a fixing part that protrudes slightly diagonally forward from the intersection in the opposite direction to the horizontal part, and a waterproof sheet is sandwiched between both ends of the water stop plate body and both ends of the water stop plate body. It is characterized in that it is brought into close contact with each other so as to overlap each other and is firmly fixed by an integral fixture.

The method for mounting the waterstop plate according to claim 2 is provided at both ends of the waterstop plate main body in a state in which the waterstop plate main body according to claim 1 is curved so as to protrude in the direction in which water flows. The orthogonal horizontal and vertical parts of the substantially L-shaped mounting tool are placed along the mounting corners on the left and right of the opening, and the mounting tool is pressure-welded and locked to the mounting corners by the elastic repulsive force of the waterstop body. It is characterized by.

The waterstop plate of the present invention is a waterstop plate fixed to the mounting corners on the left and right of the opening, and the waterstop plates are provided at both ends of an elastic flat plate-shaped waterstop plate main body and the waterstop plate main body. by consist fixture and which can prevent so when they are stored without using can keep on plates, without taking a large place, damage or deformation of the plate in a state where the curved .. In addition, the rigid fixture consists of a horizontal part that is locked along the mounting corner and is orthogonal to a substantially L-shape, a vertical part, and a fixing part that protrudes slightly diagonally forward from the horizontal part. Since the fixing parts are brought into close contact with both ends of the waterstop body so that they overlap each other and are firmly fixed by the fixing tool for integration, they are curved during use and attached to the left and right mounting corners of the opening with elastic repulsive force. The tool can be securely and firmly pressure-welded and locked, and the water stop plate can be firmly installed without the fitting made of a highly rigid material being deformed by water pressure. Further, since waterstop body and the fixture are integrated, it can be attached anywhere it is not necessary to pre-attach the fixture to the opening. Further, since the waterproof sheet is sandwiched between the water stop plate main body and the fixing portion of the fixture and brought into close contact with each other, the watertightness can be further improved in the installation of the water stop plate.

In the invention of claim 2, the waterstop plate according to claim 1 is used, and the waterstop plate main body is provided at both ends of the waterstop plate main body in a state of being curved so as to project in the direction in which water flows. Since the rigid mounting part can be pressure-welded and locked to the mounting corner by the elastic repulsive force of the waterstop body along the mounting corners on the left and right of the opening, the elastic repulsive force of the waterstop body The vertical portion is pressed against the vertical surface of the mounting corner, and the water stream presses the horizontal portion, so that the mounting tool is firmly pressed against the mounting corner. In addition, since the water flow that hits the waterstop also flows laterally along the curved waterstop, part of the water pressure that hits the waterstop flows laterally and can withstand a larger amount of water. Can be done.

It is a top view of the waterstop (curved state). It is a front view of a waterstop. It is a perspective view which shows the structure which attached the waterstop to the opening. It is a perspective view which shows the detail of the mounting structure in FIG. It is a top view of FIG. It is a perspective view which shows the other embodiment.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following embodiments are merely exemplary and are not intended to limit the present invention, its applications or its uses.

FIG. 1 is a plan view showing a waterstop plate 1 in a curved state of the present invention, and FIG. 2 is a front view. The waterstop plate 1 has elasticity and is provided at both ends of the waterstop plate main body 11 and the waterstop plate main body, which are flat when not bent by applying a bending load, and is integrated with the waterstop plate main body. Consists of tool 2. The waterstop body 11 is a fiber-resin composite such as FRP or CFRP in which most of the fibers are oriented in one direction and fixed with a resin. Basically, the orientation direction of the fibers is in the vertical (short) direction. Orientation. As a result, the waterstop is difficult to bend in the direction in which the fibers are orthogonal (bent) and easy to bend in the fiber direction. By utilizing this property, the waterstop main body 11 can be easily curved by hand with the center line 1c as the most protruding portion.

In the conventional waterstop, when a curved one is required, it is molded by using a mold material in advance, but it is necessary to use an expensive mold material, and molding is also troublesome. In addition, the curved waterstop may take up a lot of space for storage, or may be deformed or damaged during storage, making it unusable. However, the waterstop of the present invention does not need to be molded in advance. A waterstop that is curved on the spot can be easily obtained according to the dimensions 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, when water pressure is applied to the resin portion without fibers, it is easily deformed, but the fibers are oriented in one direction (short direction). By making a part of the above orthogonal direction (longitudinal direction), it is possible to cope with water pressure from various directions. The ratio of fiber orientation in both the width and length directions must be balanced between ease of molding and strength, but 20 to 50% of the fibers oriented in the lateral direction are fibers oriented in the longitudinal direction. Is preferable.

The fibrous resin composite (specific gravity 1.5 to 2.0) used for the waterstop main body 11 is made of iron (specific gravity 7.8) or lightweight aluminum (specific gravity 2.7) used in the conventional waterstop. It is lighter in comparison and can be worked by one person. Glass fiber or the like can be used as the fiber, but by using high-strength carbon fiber, a lighter weight and higher-strength fiber-resin composite, that is, a waterstop main body 11 can be obtained.

As the fiber used for the fiber-resin composite, a plurality of layers of sheets in which various reinforcing fibers such as glass fiber and carbon fiber are oriented in one direction, even if they are short fibers or long fibers, can be laminated. Thereby, the orientation ratio of the fibers in the lateral direction and the longitudinal direction can be easily adjusted in order to balance the ease of molding and the strength. Further, 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 lateral direction, and a glass fiber sheet is appropriately combined as the core layer in a multi-layer fiber orientation to balance strength and cost. It is possible to obtain a waterstop plate that has been removed.

The left and right fixtures 2 have a substantially L-shape in which the horizontal portion 21 and the vertical portion 22 are orthogonal to each other, and stop the fixing portion 23 which protrudes slightly diagonally from the horizontal portion in the direction of water inflow from the intersection of the L-shape. It is brought into close contact with the end of the water plate main body 11 so as to overlap with each other, and is firmly fixed by the integrating fixture 3. If an adhesive is also used at this time, it can be fixed with even higher watertightness. The fixture 2 uses a rigid metal, but a rigid and rigid resin can also be used. The horizontal portion 21 is placed along the horizontal plane (facing the direction in which water flows in) of the mounting corner portion B, and the vertical portion 22 is placed along the vertical plane which is perpendicular to the horizontal plane and faces the other mounting corner portions. If necessary, a commercially available waterproof sheet is sandwiched between the water stop plate main body 11 and the fixing portion 23 to bring them into close contact with each other, so that the watertightness can be further improved.

Next, a method of mounting the waterstop plate 1 in the opening A will be described. In the present invention, it is not necessary to install a metal fitting or the like on the mounting corner B to fix the waterstop, and the elastic flat waterstop main body 11 is curved to attach the mounting tool 2 to the mounting corner B. If they are locked along the line, they can be fixed by the elastic repulsive force of the waterstop main body 11 in the direction indicated by the arrow in FIG. When the water flow hits the waterstop main body 11 in this state, it is pushed by the water pressure, the vertical portion 22 is further pressed against the vertical surface, and the horizontal portion 21 is also directly pressed against the horizontal surface by the water pressure. It is firmly fixed.

If necessary, an elastic packing is attached to the portion of the waterstop main body 11 in contact with the floor surface, or a soft resin is partially formed so that the portion of the waterstop plate main body 11 can be brought into close contact with the floor surface even if it is uneven. Similarly, by attaching a watertight packing to the substantially L-shaped inner surface of the fixture 2, the watertightness can be further improved even when there is some unevenness such as a concrete mounting corner B.

FIG. 6 shows a case where a plurality of waterstop plates 11 are stacked and used, assuming a case where the water level is higher as another embodiment. The basic configuration is the same as that described above, and packing 5 is attached to the vertically overlapping portion to improve watertightness. If the upper and lower water stop plates 11 can be fitted at the packing portion, the water stop plate main body 11 can be more stably fixed.

Since the waterstop plate installed in this way does not need to be provided with mounting brackets in advance, unnecessary brackets do not make the entrance part, which can be said to be the face of the building, look bad except in an emergency, and it is a convenience store. It does not interfere with the opening and closing of the entrance door where most of the opening is made of glass as in stores such as.

The present invention is a lightweight waterstop that can be easily curved, and since mounting tools are provided at both ends, even one person can easily work in an emergency, and it can be mounted anywhere, which is extremely useful. High industrial applicability.
