Description

  The present invention relates to a simple waterproof device that can be freely installed at an entrance of a building or the like that opens toward a road, an entrance of a subway station, an entrance of an underground parking lot, or the like.

  A simple waterproof device installed at the entrance opening of a building, etc., when the road is flooded due to flooding or torrential rain, etc. This facility is installed to prevent water from entering from the entrances and exits of commercial facilities, underground parking lots, etc., but this device has a water stop plate to prevent people and cars from entering and exiting during normal times. It is removed and stored in a hangar or the like, taken out in case of emergency such as water discharge, and attached to the entrance / exit to prevent water from entering buildings and underground facilities.

  This waterproof device has a structure that uses a power to open and close the waterproofing water stop plate, or the water stop plate is stored in a storage room provided under the entrance where the waterproof device is installed to prevent traffic. Devices with different structures such as those that are not designed have been proposed, but as a device that is simple in structure and relatively easy to handle, it is installed vertically on the side wall of the entrance and exit A simple waterproof device with a structure that forms a groove and forms a horizontally long plate body, that is, fits both ends of the waterstop plate manually, drops it to create a weir of the required height, and closes the entrance Is widely known and has been put to practical use.

  In this type of waterproofing device that attaches and detaches a water stop plate that can be said to be a popular type, the water stop plate constituting the weir plate is divided into a plurality of horizontally long plates in advance to make it easier to handle. However, in any case, this type of waterproofing device is stored and stored in a hangar or the like provided in a place that does not obstruct passage by removing the water stop plate that has been divided and reduced in size during normal times. In this way, it is structured such that it is taken out from this storage place and inserted into the mounting groove in the event of emergency use such as flooding, and the entrance / exit is blocked.

  This waterproof device with a structure that attaches and detaches the water stop plate is simple in structure and easy to install, and does not require special power for opening and closing, so there is a risk of malfunction in emergency use. In addition, since it can be handled by inserting / removing the water stop plate, it is simple and widely used.

  However, one difficulty in this apparatus is that a mounting groove for mounting a water stop plate must be installed in an entrance of a building or the like in advance.

  In addition to being designed to have a structure suitable for the water stop plate to be mounted, the mounting groove is constructed in advance opposite to the left and right surfaces of the entrance / exit. However, since the water stop plate to be attached to this does not provide a water stop effect simply by fitting it into the mounting groove, the mounting groove has a seal material on the inner wall surface of the groove to provide a reliable waterproof effect. Is inserted between the sealing plate and the sealing material to be fitted, and in order for the sealing material to function effectively, the mounting groove and the sealing material, and the sealing material and the sealing water Usually, a clamping means such as a crescent is used in combination so that the plate can be securely adhered and water can be stopped.

  Therefore, in the waterproof device having a waterproof structure in which a water stop plate is mounted in the mounting groove, it is relatively easy to handle, but as an absolute requirement, the mounting groove must be installed in the entrance and exit in advance. That is, there is a decisive problem that a water stop plate cannot be installed at an entrance / exit that does not have a mounting groove.

At the same time, in addition to installing the installation groove in advance, the installation work of the installation groove itself is costly, and if it is installed later at the entrance of a building or the like, the cost burden increases further. There is. Of course, in the waterproof device of the type using the mounting groove, as described above, the seal material is installed inside the mounting groove and the fastening means is assembled, so that a corresponding cost is required.
In addition, as another problem, for example, in the case of an entrance / exit of a store or the like that emphasizes decorativeness, there is a problem that it is difficult to install the mounting groove itself in terms of appearance.

Patent Document 1 discloses an example of a type in which a water stop plate is dropped into the mounting groove (groove of a grooved column) to close an entrance / exit opening. Here, a predetermined mounting groove is provided, and a sealing material is provided in the mounting groove, and a fixing handle as a fastening means for compressing the sealing material is provided in the water stop plate to be installed in the mounting groove. It is described that
However, in the waterproof device described in Document 1, it is essential to install a mounting groove, and a fastening handle for tightening is also an essential element, and further simplification cannot be expected.

JP2003-278458A.

Therefore, as is apparent from the above description, the present invention does not need to provide a mounting groove for mounting the water stop plate in installing the waterproof device in the entrance / exit opening, but only put it in a proper position in the opening. An object of the present invention is to provide a simple waterproof device that can stop water by a simple operation and can easily prevent water from entering a facility such as a building.
In particular, the present invention eliminates the construction cost by not using a mounting groove, and is a simple waterproof that can be used immediately without requiring special processing even for an existing entrance / exit that does not have this mounting groove. To provide an apparatus.

  In order to achieve the above object, the present invention provides a water stop plate having an L-shaped cross section integrally including a horizontal plate portion and a water stop plate portion standing upright from a rear edge portion of the plate portion, and the water stop plate. The present invention provides a simple waterproof device comprising at least a pair of fixed weights for fixing a plate in place.

  More specifically, the present invention relates to a water stop plate which is formed in an L-shaped cross section by standing a water stop plate portion from a rear edge portion of a horizontal plate portion placed on the entrance / exit floor surface, and the horizontal plate portion. A simple waterproof device comprising: at least a pair of fixed weights placed on the back and abutting the back portion against the front surface of the water stop plate portion to fix the water stop plate in place; The water stop plate is provided with an elastic seal material covering the entire width on the lower surface of the horizontal plate portion, and with an elastic seal material vertically attached to both sides of the back surface of the water stop plate portion. In this case, the water stop plate is temporarily placed and installed at a predetermined position on the floor surface of the entrance and exit, and then the pair of fixed weights are mounted on the left and right side edges of the horizontal plate portion of the water stop plate, respectively. The elastic seal material attached to the lower surface with its weight is pressed and adhered onto the floor surface of the entrance and exit, and at the same time, each fixed weight The respective back portions are pressed against and contacted with the front surfaces of the left and right side edges of the water blocking plate portion, and the elastic seal members attached to the back surface thereof are pressed and adhered to the front surfaces of the left and right side portions of the entrance / exit opening, Accordingly, an object of the present invention is to provide a simple waterproof device that prevents water from entering the opening of the entrance / exit.

  The water stop plate is formed by integrally forming a horizontal plate portion and a water stop plate portion using, for example, a thin metal plate having a required rigidity. In this integral molding, the molding method is not particularly specified. However, as the simplest method, a metal plate is cut into a horizontally long rectangular shape and bent at a right angle at a substantially central portion in the vertical direction. The water stop plate portion can be integrally formed in a state of standing upright from the rear edge portion of the portion.

  The lateral width of the water stop plate is determined in accordance with the opening width of the entrance to be waterproofed. For example, when the opening width is 1200 mm, the width that can cover the left and right sidewalls of the opening or the front part of the left and right pillars, that is, in the case of the pillar, the width of the front face is 130 mm. For example, a width of about 1460 mm is added to this.

On the other hand, the width before and after the horizontal plate portion of the water stop plate is a state in which the water stop plate portion is raised when placed on the floor surface of the doorway, that is, a width that can stand by itself, and is described later. A width that allows the weight to be placed on the upper surface is required.
In addition, as for the water stop plate part, since this water stop plate part substantially stops water when waterproofing, its height is assumed based on the height of the water level that it is supposed to stop. The height will be set above the water level. In the present invention, a standard height of about 350 mm is assumed on the assumption that the waterproof device is a simple type.

On the other hand, the pair of fixed weights for fixing the water stop plate stably fix the water stop plate at a predetermined position, and press and compress the elastic seal material attached to the water stop plate to stop the water stop plate. A metal material or a concrete material is selected from the viewpoint of obtaining a water effect and obtaining a weight that does not move by receiving external water pressure, that is, a required weight, and from the viewpoint of ease of forming.
The fixed weight is formed in a block shape to stabilize the bottom surface portion placed on the waterstop plate with a smooth surface, while the back portion is formed so as to be substantially perpendicular to the bottom surface portion. It forms so that it can press-contact to the front surface of a water stop board part. It is also convenient to carry by making it into a block shape.

The elastic seal material attached to the horizontal plate portion and the water stop plate portion of the water stop plate is easily deformed against the elastic repulsion when pressed by a fixed weight, and between the floor surface and the wall surface. A water-resistant material that can fill in the fine gaps that can be formed, such as a seal material made of rubber or synthetic resin, is suitable, and a strip-shaped material having a required thickness is suitable.
In addition, it is preferable to attach this elastic seal material over the entire width of the lower surface of the horizontal plate portion, particularly along the rear edge portion, in order to increase the water stop effect. It is required that the elastic seal material attached to the back surface portions of the left and right side portions of the water plate portion be provided over the entire length along the edge of the back surface portion. However, it is desirable that the elastic seal material is aligned with the lower end of the water stop plate portion at the lower end portion and is continuous with the elastic seal material attached thereto, but the upper end portion is for water stop. A height that exceeds the assumed water level is sufficient.

Moreover, this invention attaches the attitude | position auxiliary | assistance material which maintains the horizontal state of this horizontal board part in the appropriate position of the front side which attaches the said elastic seal material with respect to the lower surface of the horizontal board part of the said water stop board. An object of the present invention is to provide a simple waterproof device.
The posture assisting material is for correcting that the bottom surface portion of the horizontal plate portion is inclined due to the installation of the elastic seal material, and the water stop effect of the seal material is lowered. Things are suitable.

Further, the present invention provides a simple waterproof device characterized in that one or a plurality of reinforcing ribs for reinforcing the water stop plate portion are integrally attached to the front surface of the water stop plate portion of the water stop plate. It is to provide.
This reinforcing rib is for protecting the water stop plate formed of a thin material, in particular, the water stop plate portion from water pressure, and is provided mainly in the central portion or in a direction transverse to the upper edge portion. Will do.

In the present invention, an extension portion is integrally provided in front of the bottom portion of the fixed weight and above the rear portion thereof to extend each contact area of the water stop plate with respect to the horizontal plate portion and the water stop plate portion. An object of the present invention is to provide a simple waterproof device characterized by the above.
Since this fixed weight is desired to be able to reliably compress each elastic seal member by pressing the horizontal plate portion and the water stop plate portion more stably when fixing the water stop plate, its main body portion It is desired that the area of contact be widened while being easy to carry.

It is another object of the present invention to provide a simple waterproof device, characterized in that a handle is provided with a rearwardly raised and inclined front lower portion at the center of the upper surface of the fixed weight.
This handle is used for carrying and moving conveniently and for pressing the fixed weight against the water stop plate, and has an advantage that it can be easily placed at a fixed position with respect to the water stop plate.

From the above configuration, according to the present invention, the conventional structure has a very simple and simple structure including a water stop plate and a fixed weight for installing and fixing the water stop plate at a predetermined position of the entrance / exit opening. Compared to similar devices, it is easier to implement and has the advantage of being inexpensively obtained.
In particular, this device does not require a mounting groove for mounting a water stop plate, that is, it is not necessary to provide a mounting groove in the entrance / exit opening as in the conventional device, and at the same time, the cost can be reduced, Since it can be installed directly at the entrances and exits of existing buildings, it has the effect of greatly expanding the scope of its use.

The attached drawings represent an embodiment of a simplified waterproof device according to the present invention. Hereinafter, the present invention will be described with reference to the drawings, and the features thereof will be clarified.
In the drawings, reference numeral 1 is a water stop plate of the simplified waterproof device according to the present invention, and 2 is a fixed weight for fixing the water stop plate 1 at a fixed position.

The water stop plate 1 is formed by using a thin metal plate as a raw material. Here, a horizontal plate portion 1A and a water stop plate portion 1B are formed by bending a plate formed in a horizontally long rectangular shape at a substantially right and left central portion. Are formed so as to be integrated.
As shown in FIG. 1, the width of the water stop plate 1 is determined in accordance with the opening width of the entrance / exit opening 3 of the building or the like where the apparatus is installed. Here, the entrance / exit opening 3 is formed. The length between the front surfaces 4a and 4a of the left and right columns 4 and 4 is such that both ends of the water stop plate portion 1B are in contact with the front surfaces 4a and 4a.
As a specific example, when the width of the opening 3 is 1200 mm and the width of the front surfaces of the left and right columns 4 and 4 is 130 mm, the lateral width of the water blocking plate 1 is formed to be approximately 1460 mm. .

On the other hand, the horizontal plate portion 1A of the water stop plate 1 is formed to have a width that allows the water stop plate to stand on its front and back, and a width that allows the fixed weight 2 to be placed on the upper surface thereof as will be described later. Is done. According to the above example, it is formed in a width of about 200 mm. And about the height of the water stop board part 1B, it will form in the height exceeding this on the basis of the water level at the time of anticipated water increase, According to said example, it forms in the height of about 350 mm Is done.
In addition, the whole magnitude | size of the water stop board 1 is determined according to the magnitude | size of the entrance-and-exit opening part 3 assumed use as above-mentioned. In addition, the strength of the water stop plate 1, particularly the strength against the water pressure, is determined in consideration of this size, but at this time, it is important not to impair the weight reduction. Will be left to the choice.

  Elastic seal members 5 and 6 are attached to the horizontal plate portion 1A and the water stop plate portion 1B of the water stop plate, respectively. Both elastic seal materials 5 and 6 stop water that enters the water stop plate 1 when the water stop plate 1 is installed, and have appropriate elasticity and flexibility (flexibility). A rubber or synthetic resin seal material is suitable. Further, as shown in the figure, a strip-shaped seal material having a required thickness is suitable.

As shown in FIG. 6, the elastic seal material 5 attached to the lower surface of the horizontal plate portion 1A is attached to the entire width along the rear edge, and the elastic seal material 5 is attached to the lower surface in front of the elastic seal material. Posture auxiliary members 7, 8, 9 for preventing the horizontal plate portion 5 from being tilted forwardly by 5 are additionally provided.
The posture assisting materials 7 to 9 are made of the same kind as the elastic seal materials 5 and 6 in this embodiment, and are arranged in an appropriate manner so as to create an average horizontal posture. In addition, the weight of the fixed weight 2 with respect to the elastic seal material 5 is entirely and appropriately loaded so that it can be compressed and compressed.

  On the other hand, the elastic seal members 6 and 6 attached to both sides of the back surface of the water blocking plate portion 1B are arranged vertically along the edge. This elastic seal material stops water from entering from both sides of the back surface of the water stop plate portion 1B, and the lower end portion reaches the elastic seal material 5 so that water can be stopped jointly therewith. The upper end portion reaches the upper end of the water stop plate portion.

And in this Example, the upper and lower two reinforcement ribs 10 and 11 are formed in the horizontal direction in the front part of the waterstop board part 1B.
The reinforcing ribs 10 and 11 supplement the strength of the water stop plate portion 1B formed from a thin metal plate, and here, the water stop plate formed in a semicircular arc shape (may be a square shape) in cross section. A shape member made of the same kind of metal plate is integrally fixed to the front surface of the water stop plate portion 1B.
As shown in the drawing, the two reinforcing ribs 10 and 11 are integrally provided in the middle of the upper edge portion of the water stop plate portion and the height near the lower end.
The reinforcing ribs 10 and 11 can be removed by changing the material of the water stop plate. However, for example, if the plate thickness is increased in order to increase the strength, the weight increases and it is inconvenient to move. Therefore, careful consideration is required for the selection.

  The fixed weight 2 is a fixing means for stably pressing and fixing the waterstop plate 1. Here, the fixed weight 2 is made of metal, and its main part is formed into a right triangle when viewed from the side, One surface that forms a rectangle with a width is a bottom surface portion 2a, and one surface that is adjacent to the rectangular surface is a back portion 2b. The main body forming the right triangle is provided with an extension 2c for extending the bottom surface 2a forward and extending the lower surface, and also extending the rear portion 2b upward and extending the surface. 2d is provided. At the same time, the rear portion 2b is provided with a groove-shaped concave portion 2e for receiving the reinforcing rib 11 in the middle of the height.

Since the fixed weight 2 is a heavy object enough to be pressed and fixed, here, a U-shaped rod-like handle 12 is attached to the upper surface portion 2f inclined forward and downward.
The handle 12 is easy to carry and when it is placed on the water stop plate 1, the fixed weight 2 is slid rearward on the upper surface of the horizontal plate portion 1A, and the back portion 2b is easily placed on the front surface of the water stop plate portion 1B. It is to be pressed, and is integrally fixed vertically to the center of the upper surface portion 2f. Note that when the fixed weight 2 is placed on the water stop plate 1, the handle is inclined forward and downward, so that it is possible to easily push backward using this inclination.

Next, the actual use of the simplified water stop device according to the present invention will be described with reference to FIG.
The water stop plate 1 and the fixed weight 2 are stored and stored in a storage place away from the entrance / exit opening 3 such as a building in a normal state, and are taken out in case of emergency of water discharge.
In installation, the water stop plate 1 is first faced to the front of the opening 3 and the horizontal plate 1A is placed on the floor surface 13 and the back of the water stop plate 1B is brought close to the opening 3 The rear surfaces of the left and right sides are brought into contact with the front surfaces 4a and 4a of the left and right columns 4 and 4, respectively, thereby completing the temporary placement of the waterstop plate 1. This installation position is a fixed position, and the back surface of the water stop plate portion 1B is always in contact with the front surface of the entrance / exit opening portion 3.

When the water stop plate 1 is temporarily placed, next, the fixed weights 2 and 2 are placed on the left and right edges of the horizontal plate portion 1A of the water stop plate, respectively, and the waterproof device is installed. Will complete.
The fixed weights 2 and 2 are placed in a vertical direction (front-rear direction) along the upper surfaces of the left and right edges, and the back portion 2b is pressed against the front surface of the water stop plate portion 1B.

The waterstop plate 1 that has received the fixed weights 2 and 2 receives the weight, and the elastic seal material 5 attached to the lower surface of the horizontal plate portion 1A is pressed to be in close contact with the floor surface 13. Become. At this time, as a result of the weight acting on the posture assisting members 7, 8, and 9 similarly distributed and being compressed, the water stop plate portion 1A sinks while maintaining the level, and the elastic sheet The rubber material 5 is uniformly compressed throughout.
On the other hand, the water blocking plate portion 1B that has been pressed from the front by the fixed weights 2 and 2 is provided with elastic seal members 6 and 6 provided on the left and right rear surfaces thereof by the fixed weights 2 and 2, respectively. By pressing against the front surfaces 4a and 4a of the pillars 4 and 4 and coming into close contact with each other, a water stop effect is generated.

  As described above, the water blocking plate 1 has the floor surface 13 and the front surfaces 4 a of the left and right columns 4, 4 constituting the opening 3 with the elastic seal members 5, 6, 6 by placing the fixed weights 2, 2. 4a is enclosed, and water is stopped by being in close contact with each other, thereby preventing water from entering the opening 3.

  In the figure, reference numeral 14 denotes an auxiliary fixed weight, and this weight is placed on the water stop plate 1 as necessary. The auxiliary fixed weight 14 is used to assist in the case where the water stop plate 1 is formed in a horizontally long shape and cannot be sufficiently pressed down by the two fixed weights 2 and 2 placed on the left and right. Here, as shown in the figure, it is formed in a rectangular cubic body shape, and the smooth lower surface is placed on the horizontal plate portion 1A, and the rear portion is brought into contact with the front surface of the water stop plate portion 1B (here, it is stopped). This is used in the same manner as the fixed weights 2 and 2.

In the illustrated embodiment, three auxiliary fixed weights 14 are arranged at equal intervals on the water stop plate 1. However, in actual handling, the size of the water stop plate 1 and the auxiliary fixed weight 14 itself are as described above. The number to be arranged is determined by the size of the weight.
Since the number of the auxiliary fixed weights 14 can be arbitrarily selected, it is lighter (for example, 5 to 10 kg) than the fixed weight 2 formed to have a weight of about 13 kg. Will be formed. Of course, this weight can be freely selected by the designer and is not limited to one. The auxiliary fixed weight 14 is also provided with a handle 15 in consideration of carrying.

As is apparent from the above description, according to the present invention, the water stop plate 1 is placed close to the entrance opening 3 of the building or the like, and then 2 on the left and right edges of the water stop plate 1. Installation is completed if the fixed weights 2 and 2 are placed, and the water stop for the opening 3 is completed by this simple operation, so that it can be used through a very simple operation without requiring any special technique. become.
The simple water stop device according to the present invention includes a water stop plate 1 and a fixed weight 2 formed in an L-shaped cross section. The water stop plate includes a bottom surface of the horizontal plate portion 1A and the water stop plate portion 1B. Since it has a simple structure in which the elastic seal members 5 and 6 and 6 are attached to the back surface, the manufacture is simple and easy, and there is an advantage that it can be provided at a relatively low cost.

Furthermore, with regard to the water stop effect which is the original purpose, the elastic seal members 5 and 6 and 6 attached to the water stop plate 1 can immediately exhibit the water stop effect by placing the fixed weights 2 and 2. Therefore, the opening 3 can be reliably stopped.
And here, since it is not necessary to fix the water stop plate using a fastener such as a handle or a crescent as in the conventional device, the problem of water leakage due to an error in the tightening operation can be solved. it can.

  Further, the advantage of the present invention is that the water stop plate 1 itself can be made lightweight, and the water stop plate 1 formed of a thin plate has some flexibility while having the required rigidity. Therefore, there is an advantage that the water stop effect can be further enhanced. In other words, by having this flexibility, even when there is distortion on the floor surface 13 or the front surface of the opening 3 serving as a receiver when the fixed weights 2 and 2 are pressed, this is absorbed by the deflection, and the elastic sheet. Since the rubber materials 5 to 6 and 6 can be made to flexibly correspond to each other, a stable and more complete water-stopping effect can be obtained.

  Moreover, since this flexibility acts also on the connection part of the horizontal board part 1A of the water stop board 1 and the water stop board part 1B, ie, the part which bends at right angle, it is also in the angle which both board parts 1A and 1B make. There is a margin to change somewhat, and even if there is a slight difference in the angle between the floor surface 13 and the front surface 4a of the column, stable adhesion can be obtained.

  In addition, in the said Example, about the water stop board of the simple water stop apparatus which concerns on this invention, it has a required intensity | strength and rigidity, and also pays attention to being lightweight, and as above-mentioned, a metal thin plate The material is formed, but the material can be freely selected as long as it has the same characteristics as those described above. For example, there is no particular problem even if synthetic resin is used as a material.

  Further, in the embodiment, the entrance / exit opening 3 is used as the entrance / exit of the building, but the waterproof device of the present invention can also be effectively implemented at the entrance / exit of the elevator to the basement attached to the building. . In particular, in this case, the right and left walls of the entrance / exit and the outer surface of the column are often finished relatively smoothly, so that the adhesiveness with the elastic seal material is good, and thus a good use effect is obtained. It will also be.
