Description

INDUSTRIAL APPLICABILITY The present invention particularly preferably improves the reliability of water stoppage with respect to a waterstop plate for blocking the opening of a building to block water from the outside and preventing water from entering from the outside to the inside of the building. Regarding the waterstop.

For example, in Patent Document 1, regardless of the size of the weight of the waterproof member, a sufficient pressing force is applied to the elastic member provided at the lower end of the waterproof member to stop water from being between the waterproof member and the installation surface. As a waterproof device capable of enhancing the water resistance, a waterproof device provided with an elastic member provided at the lower end portion of the waterproof member and elastically deformable in the vertical direction and a pressing portion capable of applying a force to the elastic member is disclosed. Has been done.

When a simple waterproof device is installed on the floor outside the building opening, the above-mentioned prevention device may be used even if there is a gap between the waterproof device and the left and right building walls and squares constituting the opening. It has the feature that water does not enter the inside from the side surface side of the waterproof device.

Japanese Unexamined Patent Publication No. 2017-31758

However, if it is a conventional simple waterproof device, a person carries it and mounts the waterproof device on the floor surface outside the building opening. At that time, even if the waterproof device is carefully mounted, the waterproof device is mounted. Due to the fact that it is difficult to visually grasp the lower end side of the waterproof device, a gap is likely to occur especially on the lower end side of the waterproof device, which causes water leakage.

Further, although Patent Document 1 has an effective solution to the above problem, it is specific and complicated such that the person who places the waterproof device steps on the pressing portion with his / her foot after placing the waterproof device. Work is essential. For this reason, if a person who is not familiar with the structure and function of the waterproof device installs it, the degree of execution of the installation work is insufficient, such as not realizing or forgetting the necessity of the above work, or installation due to lack of recognition. There was a problem that water leakage occurred due to the incomplete work. These circumstances are even more worrisome because they are in an urgent situation due to unpredictable natural disasters such as heavy rains and the resulting flooding of rivers.

Therefore, the present invention was created in view of the above problems, and while reducing the number of steps for installing a waterstop, there is little concern or concern about water leakage, and water can be reliably prevented from entering from the outside. The purpose is to provide a waterstop.

In order to solve the above problems, the present invention
A waterstop that is installed almost vertically at the opening of a building.
On the surface of the waterstop opposite to the opening of the building, a swing piece having a tip protruding downward from the lower end side of the surface and swinging on the tip side so as to be inclined with respect to the surface is provided. ,
Provide a waterstop characterized by.

In the waterstop of the present invention having such a configuration, the waterstop is placed in the opening of the building (that is, in front of or behind the frontage of the building, in other words, on the outside or inside of the frontage of the building. First, for example, the tip on the lower end side of the rocking piece protruding downward from the waterstop in a state of being lifted substantially vertically comes into contact with the floor surface. In this state, if the installer releases the support of the waterstop, for example, by letting go of the waterstop, even if the waterstop and the building opening are separated, the rocking piece will be attached to the waterstop. Its tip is tilted from a state parallel to the surface opposite to the building opening (or slightly tilted from a slightly tilted state to the surface opposite to the building opening of the waterstop). Since the side can be swung, the waterstop is tilted toward the building opening side with the tip of the swinging piece as a fulcrum, and the waterstop approaches the wall surface (opening edge) or square of the building opening. Let them abut.

This series of movements is a spontaneous movement based on gravity or the like, and the installer can operate the waterstop in the direction of improving the waterstop without any consideration. Since the rocking piece is arranged on the surface of the waterstop opposite to the building opening, the waterstop falls to the building opening side due to gravity. In addition, although the swing piece can swing, the swing angle is regulated by the surface of the waterstop, so it swings only on the side opposite to the building opening, and the waterstop tilts toward the building opening side. You can surely play the effect.

Further, in the above-mentioned waterstop plate of the present invention,
It is desirable to provide a vertical hanging prevention mechanism for preventing the waterstop or the swinging piece from hanging vertically.

In the waterstop plate of the present invention having such a configuration, since the axis of the swinging piece is not completely parallel to the waterstop plate and is inclined to the side opposite to the building opening, the waterstop plate is used in the building. It can be placed closer to the opening side, and water stoppage can be improved. If the rocking piece is provided vertically, there is a risk that the waterstop will tilt to the opposite side of the building opening and tip over due to wind or other factors. The waterstop can be reliably moved toward the opening side of the building.

Further, in the above-mentioned waterstop plate of the present invention,
It is desirable that the rocking piece be provided with a length reduction mechanism for reducing the length of the rocking piece.

In the waterstop plate of the present invention having such a configuration, the length of the rocking piece can be reduced or reduced when the rocking piece receives a stress from above (this stress includes the weight of the waterstop plate itself). Therefore, the bottom surface side of the waterstop can be reliably in contact with the waterstop without rising from the floor surface, and the water stoppage on the floor surface side can be ensured.

Further, in the above-mentioned waterstop plate of the present invention,
It is desirable that the rocking piece be provided with a repulsive elastic mechanism that generates a force in a direction of repulsion when the length of the rocking piece is reduced by the length reduction mechanism.

In the waterstop plate of the present invention having such a configuration, since the repulsive force due to the repulsive elasticity mechanism can be exerted, the length of the swinging piece can be reduced smoothly and appropriately (appropriate reduction / reduction). can. Furthermore, the waterstop can be pressed toward the opening side of the building by the component force acting in the lateral direction of the repulsive force, and in particular, the waterstop near the lower end on both ends of the waterstop (in the direction of the frontage of the building opening) is ensured. Can be improved.

Further, in the above-mentioned waterstop plate of the present invention,
It is desirable that the tip of the rocking piece does not protrude downward from the lower end of the waterstop when the length is reduced by the length reduction mechanism.

In the waterstop plate of the present invention having such a configuration, a person lifts the waterstop plate substantially vertically (therefore, the rocking piece is in a state of hanging substantially vertically or slightly tilted by a vertical hanging prevention mechanism. ), When the tip of the rocking piece is pushed in to maximize the length reduction of the rocking piece (in other words, the length cannot be reduced any more), the tip of the rocking piece is on the lower end side of the waterstop. Since it does not protrude downward from (in other words, the height position of the tip of the rocking piece in the vertical direction is the same as or higher than the lower end of the waterstop), the rocking piece interferes with the waterstop. It is possible to preferably prevent the lower end from being installed in a state of floating from the floor surface. That is, when the waterstop is installed in the opening of the building, if the opening side and the opening side surface of the waterstop are already in close contact with each other, even if the waterstop is pressed from above to the floor side, the rocking piece will be generated. There is a possibility that a gap may be created between the waterstop plate and the floor surface as an obstacle, and the waterstop plate of the present invention can eliminate such a concern.

Further, in the above-mentioned waterstop plate of the present invention,
It is desirable that the rocking piece is provided with an anti-slip device at the tip.

In the waterstop plate of the present invention having such a configuration, the rocking piece swings in the process of installing the waterstop by providing a non-slip tool at the tip on the lower end side of the rocking piece, and the installation angle. Even if the waterstop changes, the tip of the rocking piece catches the floor surface and an appropriate repulsive force can be obtained.

Further, in the above-mentioned waterstop plate of the present invention,
It is desirable to provide a pressing mechanism that presses the lower end side of the waterstop against the floor surface of the building opening.

The waterstop plate of the present invention having such a configuration is provided with a pressing mechanism for pressing the waterstop plate from above to downward to ensure contact between the waterstop plate and the floor surface and to the floor surface. The water stoppage of the waterstop can be secured and improved, and the repulsive elasticity mechanism works effectively to secure and improve the watertightness of the entire waterstop. When the waterstop is provided with a pressing mechanism, if the above-mentioned swing piece is not provided, a gap remains between the waterstop and the opening side of the building (especially a gap on the lower end side of the waterstop). When the pressing mechanism is operated (with the waterstop plate tilted), the gap is fixed and there is a concern that water leakage may occur. To be prepared, there is no such concern.

According to the present invention, it is possible to provide a waterstop plate that can eliminate the fear and concern of water leakage and surely prevent the intrusion of water from the outside of the building while reducing the number of steps of installing the waterstop plate. While conventional waterproofing devices require complicated and multi-step measures to ensure waterproofing near the lower end on both ends of the waterproofing device (in the direction of the frontage of the building opening), the installer usually takes measures. If installed with caution, it is possible to automatically secure water stoppage near the lower end on both ends of the waterproof device (in the direction of the frontage of the building opening), reduce the number of installation processes, and simplify the order (procedure) of each process. can do. With due care, the installer does not have to think deeply in an emergency situation, does not have to reread the installation procedure manuals and precautionary statements, performs the installation work intuitively and quickly, and ensures high water stoppage. be able to.

Therefore, the ratios and numbers are exaggerated or simplified as necessary for easy understanding. It may be expressed as a conversion. Further, in the following description, the same or corresponding parts may be designated by the same reference numerals, and duplicate description may be omitted.

1. 1. Outline of the waterstop plate 1 An outline of the waterstop plate 1 according to the embodiment of the present invention will be described with reference to FIG. FIG. 1 is a schematic diagram illustrating an outline of the waterstop plate 1 in the present embodiment. As shown in FIG. 1, the waterstop plate 1 of the present embodiment prevents a large amount of water such as a flood generated in an emergency from flowing in the direction X of the arrow.

More specifically, the waterstop plate 1 of the present embodiment prevents water from flowing from the building outer side 107 to the building inner side 105 through the building opening 101 provided at the entrance / exit of the building. .. Examples of the building frontage 101 include doors and doors of houses and buildings, windows, entrances and exits of exterior structures, entrances and exits to underground malls and parking lots, and the like.

2. 2. Structure of the waterstop plate 1 The waterstop plate 1 of the present embodiment generally has a waterstop plate main body 2 installed in contact with the building opening 101 and a waterstop plate main body 2 (the surface opposite to the building opening, that is, water stoppage). A plurality of (three in this embodiment) rocking pieces arranged below the surface of the plate body 2 on the outside side 107 of the building and urging the waterstop body 2 diagonally upward on the building opening 101 side. 3 and a pressing mechanism 103 (in this embodiment, one on each of the left and right ends of the waterstop body 2) that presses the waterstop body 2 downward (on the floor surface 109 side), and the waterstop packing 13. It is equipped and configured.

<Waterstop body 2>
The waterstop main body 2 is a substantially rectangular plate-shaped member having a substantially parallel first surface (front surface) and a second surface (rear surface) and having a predetermined thickness, and serves as a waterstop plate. It is constructed by using various materials as long as it functions and does not impair the effect of the present invention.

The waterstop main body 2 may be made of resin or metal, or may be made of a plurality of materials. For example, the main part of the waterstop main body 2 may be made of resin, and a metal frame material may be provided on the peripheral edge thereof. It may have at least a first surface and a second surface, and may have a hollow structure in which the two surfaces are connected by a crosspiece structure.

<Pressing mechanism 103>
The waterstop plate main body 2 of the present embodiment has a pressing mechanism 103 that presses the waterstop plate main body 2 downward (floor surface 109 side) after abutting on the opening edge 111 in a state of being placed on the floor surface 109. The waterstop main body 2 can be fixedly installed on the frontage 101 of the building in a short time, easily and surely after adjusting the arrangement. As the pressing mechanism 103, for example, the mechanism disclosed in Japanese Patent Application Laid-Open No. 2017-160693 can be adopted.

<Water-stopping packing 13A and water-stopping packing 13B>
As shown in FIG. 1, water stop packings 13A extending in the height direction of the water stop plate main body 2 are arranged at both ends of the water stop plate main body 2 in the frontage direction. The water stop packing 13A can be made of a rubber material, a resin material, a resin foam, an air bag, or the like, and when water pressure is applied to the water stop plate 1, it elastically deforms to receive the water pressure and stops water. It has a function as a so-called sealing material or packing that seals between the plate body 2 and the opening edge 111 so as not to leak water. The waterproof packing 13A may be attached to the end edge 111 side of the opening.

Further, a water stop packing 13B is arranged on the lower horizontal portion of the water stop plate main body 2. The waterstop packing 13B can also be made of a rubber material, a resin material, a resin foam, an air bag, or the like, and is elastically deformed by the weight of the waterstop 1 or the pressing force at the time of installation, and the waterstop main body. Seal between 2 and the floor surface 109 so that water leakage does not occur. The waterproof packing 13A and the waterproof packing 13B may be configured as a single continuous member. Needless to say, these waterproof packings 13 are not essential components if desired waterproofness can be expected.

<Swing piece 3>
Next, the structure of the rocking piece 3 will be described in detail with reference to FIGS. 2 (a) and 2 (b) and FIGS. 3 (a) and 3 (b). 2A and 2B are views showing the structure of the rocking piece 3, FIG. 2A is a front view of the rocking piece 3, and FIG. 2B is a rocking piece. It is a side view of piece 3. 3A and 3B are views showing a reduction mechanism of the main body portion 5, FIG. 3A is a cross-sectional view of the main body portion 5 in a normal state, and FIG. 3B is a cross-sectional view. It is sectional drawing of the main body part 5 at the time of shrinkage. The rocking piece 3 is a component arranged below the waterstop main body 2 as described above, and the tip on the lower side abuts on the floor surface 109, and the waterstop main body 2 is diagonally upward on the building opening 101 side. It is something to be urged.

As shown in FIGS. 2A and 2B, the swing piece 3 has a main body portion 5 (reduction mechanism) composed of a cylinder portion 19, a rod portion 21, and a coil spring 9 (anti-elastic mechanism), and a rod portion 21. It is composed of an anti-slip tool 11 arranged at the lower end of the cylinder portion 19 and a hinge 17 arranged on the upper side surface of the cylinder portion 19.

The cylinder portion 19 is substantially cylindrical and has a hollow portion 23 inside, and the upper end is closed and the lower end is opened so that the rod portion 21 can be inserted. The rod portion 21 is substantially rod-shaped and has a shape in which the upper portion can be inserted into the hollow portion 23 of the cylinder portion 19 and the stress of the coil spring 9 can be reliably received. More specifically, the upper part of the rod portion 21 is smaller than the diameter of the hollow portion 23 of the cylinder portion 19, and has a smooth surface (larger than the diameter of the coil spring 9) perpendicular to the axial direction of the cylinder portion 19 at the upper end. I have.

The coil spring 9 is inserted into the hollow portion 23 of the cylinder portion 19, and the upper side of the rod portion 21 is inserted into the hollow portion 23 while compressing the coil spring 9 in the axial direction of the cylinder portion 19, and these three parts are fitted. A retaining 26 is provided at the lower end of the cylinder portion 19 so that the fitting is not released.

With the above configuration, the cylinder portion 19 and the rod portion 21 of the main body portion 5 can slide with each other in the axial direction, and the length can be reduced or reduced. More specifically, as shown in FIG. 3A, in the main body portion 5 in the normal state, the coil spring 9 in the hollow portion 23 extends in the axial direction of the cylinder portion 19 to transmit stress to the rod portion 21. The rod portion 21 is in a state of being most protruding below the cylinder portion 19, but as shown in FIG. 3 (b), a load is applied from below to above the rod portion 21 (in the axial direction of the cylinder portion 19). , The rod portion 21 can slide in the hollow portion 23 while pressing and compressing the coil spring 9.

To prevent the main body 5 from excessively shrinking beyond a predetermined range, for example, a component that limits the sliding range of the rod portion 21 in the hollow portion 23 is added, and a length shrinking stopper (not shown) is added. May be provided.

The sizes of the cylinder portion 19, the hollow portion 23, the rod portion 21, and the coil spring 9 (including stress for the coil spring 9) constituting the main body portion 5 are generally the size and weight of the waterstop plate main body 2 and the amount of reduction. It may be decided appropriately in consideration of. Further, each of the above parts may be formed by using a metal material having corrosion resistance such as stainless steel or aluminum, a resin material having high rigidity, or the like.

In this embodiment, an example using a substantially cylindrical cylinder portion 19 and a coil spring 9 is illustrated, but instead of the substantially cylindrical cylinder portion 19, a cylinder having a rectangular, square, or polygonal cross section is used. A shaped body may be used, or instead of a method using a coil spring 9, a swing piece having a length reduction mechanism and a repulsion elastic mechanism is used by a method such as an air cylinder, a hydraulic cylinder, or a hydraulic cylinder. May be good.

Further, as another embodiment, the connection between the rocking piece 3 and the rocking piece connecting surface 27 of the waterstop main body 2 described later is in a manner in which the connection position can be moved in the vertical direction and swingable. It may be connected and configured to have impact resilience. Specifically, the connecting portion of the swinging piece 3 is slidably engaged and connected to the rail body formed in the vertical direction with respect to the swinging piece connecting surface 27, and the connecting portion of the swinging piece 3 is slidably engaged and connected to the rail. An embodiment such as providing a spring having a downward impact resilience can be exemplified.

It is desirable that the anti-slip tool 11 is made of a flexible, elastic, non-slip material such as rubber or elastomer resin. A hollow body or a foam may be used. It is possible to prevent slipping by biting into the floor surface 109 with a metal pin or needle shape, but the contact area can be optimized by changing the angle and position of contact with the floor surface 109 every moment. , It is desirable to have a substantially hemispherical shape.

The anti-slip tool 11 may be formed separately from the rod portion 21 or integrally formed, but it is necessary to securely fix the anti-slip tool 11 so as not to fall off from the lower end of the rod portion 21 of the main body portion 5, and an adhesive is used. It is desirable to firmly fix it with bolts, screws, etc.

<Hinge 17>
The hinge 17 used in the present embodiment is a component used for a general building material or the like in which two plates are connected by forming a hinge on both end faces and rotatably fitted, and is made of stainless steel or aluminum. It is desirable that it is formed of a metal material or the like having corrosion resistance such as. The hinge 17 used in the present embodiment is composed of a first plate 17A connected to the waterstop main body 2 and a second plate 17B connected to the cylinder portion 19 of the main body 5.

The first plate 17A is provided with a connection hole 25 for connecting the hinge 17 to the waterstop main body 2. Like the first plate 17A, the second plate 17B may be connected to the cylinder portion 19 by providing holes or the like and screw fitting with screws or the like, but may be connected to the cylinder portion 19 by welding or the like.

For the connection between the hinge 17 and the waterstop main body 2, a known method such as screw fixing using the connection hole 25 or adhesive fixing can be used. When screw fixing is used, the second plate 17B is provided with a through hole for allowing the screw head to escape, thereby preventing interference with the swing of the swing piece 3. By omitting the formation of the through hole and allowing the screw head to come into contact with the second plate 17B, it may be substituted as a vertical hanging prevention mechanism described later.

3. 3. Connection between the waterstop plate main body 2 and the rocking piece 3 Subsequently, the connection between the waterstop plate main body 2 and the rocking piece 3 will be described with reference to FIGS. 4A and 4B. 4 (a) and 4 (b) are views showing the connection between the waterstop plate main body 2 and the rocking piece 3, and FIG. 4A is a view showing a swinging piece contact portion with the waterstop plate main body 2. 7 is a side view of the lower part of the waterstop plate main body 2 provided with 7, and 4 (b) is a side view of the lower part of the waterstop plate main body 2 provided with the waterstop plate main body contact portion 4 on the rocking piece 3. Hereinafter, the floor surface 109 direction will be referred to as P2, and the opposite direction will be referred to as P1.

As described above, the rocking piece 3 is connected below the rocking piece connecting surface 27 (the surface opposite to the building opening 101) of the waterstop main body 2, and the lower end is oriented toward P2 in the substantially direction. A hinge 17 is used for the connection between the rocking piece 3 and the waterstop main body 2, but it is desirable that the rotation of the hinge 17 is set in the rotation direction P4. It should be noted that the number of rocking pieces 3 to be connected may be appropriately determined according to the size of the waterstop main body 2, and it goes without saying that the number of rocking pieces 3 may be one, for example.

<Vertical sagging prevention mechanism>
When the rocking piece 3 hangs vertically with respect to the floor surface 109 with the waterstop plate main body 2 lifted in the direction P1 (that is, substantially vertical), the waterstop plate main body 3 is used as an axis. There is a risk that 2 will stand up in a balanced manner and will incline to areas other than the building opening 101 side. Therefore, even when the waterstop main body 2 is lifted in the direction P1, the rocking piece 3 is provided so that the angle θ1 between the axis of the rocking piece 3 and the rocking piece connecting surface 27 does not become less than a predetermined value. A vertical hanging prevention mechanism that inclines in the direction opposite to the building opening 101 is arranged below the rocking piece connecting surface 27.

With this configuration, when the waterstop plate 1 is installed on the floor surface 109 on the building opening 101 side, the rocking piece 3 has an angle with respect to the floor surface 109 when it is placed on the floor surface 109 on the building opening 101 side. The waterstop plate 1 can be urged to the building opening 101 side. In other words, when the rocking piece 3 hangs vertically, the tip of the rocking piece 3 and the floor surface 109 are in a state of frontal collision, and the waterstop body 2 is on either side (inside the building). It is not possible to determine whether the waterstop will fall to 105 or the outside side of the building 107), but with the above configuration, the waterstop plate 1 is surely located inside the building 105 (that is, the inside side of the building 105) due to the relationship between the center of gravity of the waterstop plate 1 and gravity. , The waterstop plate 1 can be urged to the building opening 101 side in cooperation with the pressing mechanism 103, the length reduction mechanism of the swing piece 3, and the repulsive elasticity mechanism.

The vertical hanging prevention mechanism is a component disposed between the waterstop plate main body 2 and the rocking piece 3, and in the present embodiment, it has a protruding shape protruding from the rocking piece connecting surface 27 of the waterstop plate main body 2. A rocking piece contact portion 7 is formed on the surface. A more specific forming position for the rocking piece contact portion 7 is a position below the connecting portion on the rocking piece connecting surface 27, where the rocking piece 3 swings and can be contacted. By disposing the rocking piece contact portion 7, the rocking piece 3 comes into contact with the tip of the rocking piece contact portion 7, so that the vertical position and the protruding height of the rocking piece contact portion 7 By selecting, the lower limit of the angle θ1 between the axis of the rocking piece 3 and the rocking piece connecting surface 27 can be determined. In the present embodiment, the rocking piece contact portion 7 protruding from the rocking piece connecting surface 27 is exemplified, but instead of this, the water stop portion protruding from the rocking piece 3 and capable of contacting the rocking piece connecting surface 27 is stopped. It is also possible to make an embodiment using the plate body contact portion 4.

The angle θ1 between the axis of the rocking piece 3 and the rocking piece connecting surface 27 is preferably in the range of 1 degree to 45 degrees, but if the angle θ1 is large, it slips when the waterstop plate 1 is installed. If the preventive tool 11 slips on the floor surface 109 and the tip of the rocking piece 3 escapes, and conversely, if the angle θ1 is small, the tilt angle of the rocking piece 3 is insufficient and the waterstop plate 1 moves in an unintended direction. Since there is a risk of falling, it is more preferable to set the temperature to 5 to 30 degrees even within the above range.

As a specific connection position of the swing piece 3 to the waterstop main body 2, the anti-slip tool 11 on the lower end side of the rod portion 21 with the swing piece 3 in contact with the swing piece contact portion 7. The tip (corresponding to the tip of the rocking piece 3) is projected from the lower end surface of the waterstop main body 2 toward P2 in the direction, and the lowermost position of the cylinder portion P3 (the length is most reduced by the length reduction mechanism). It is desirable to position (corresponding to the tip of the rocking piece 3 in this state) on the P1 side in the direction from the lower end surface of the waterstop main body 2.

If the tip of the anti-slip tool 11 on the lower end side of the rod portion 21 protrudes toward P2 in the direction from the lower end surface of the waterstop main body 2, it is ahead of the lower end surface of the waterstop plate main body 2 when the waterstop plate 1 is installed. The anti-slip tool 11 (corresponding to the tip of the rocking piece 3) can be brought into contact with the floor surface 109. Further, even if the length of the main body portion 5 is reduced and the rod portion 21 slides toward the cylinder portion 19, the cylinder portion 19 does not directly contact the floor surface 109, so that the lower end surface of the waterstop plate main body 2 and the floor Poor contact with the surface 109 does not occur.

4. Method of Installing Waterstop 1 in Building Opening 101 Next, a method of installing the waterstop 1 of the present embodiment in building opening 101 will be described in detail with reference to FIGS. 5 to 7. 5 (a) and 5 (b) are views showing a state in which the water stop plate 1 is placed in the building opening 101, and FIG. 5 (a) shows the water stop plate 1 brought close to the building opening 101. It is a plan view which shows the state, and FIG. 5 (b) is a side view which shows the state which brought the waterstop plate 1 close to a building opening 101. Further, FIG. 6 is a side view showing a state in which the waterstop plate 1 is in contact with the opening edge 111, and FIG. 7 is a side view showing a state in which the waterstop plate 1 is installed in the building opening 101.

As shown in FIGS. 5A and 5B, first, the waterstop plate 1 of the present embodiment is placed in the vicinity of the building opening 101. In this embodiment, the mode in which the waterstop plate 1 is installed facing the building opening 101 from the building outer side 107 will be described as a representative, but the mode in which the waterstop 1 is installed facing the building opening 101 from the building inner side 105 will be described. May be.

The waterstop plate 1 is lifted so that the rocking piece connecting surface 27 approaches the building opening 101 while facing the building outer side 107 in a state where the tip of the rocking piece 3 does not contact the floor surface 109. After the waterstop plate 1 is brought as close to the building opening 101 as possible, the waterstop plate 1 is lowered to bring the tip of the rocking piece 3 into contact with the floor surface 109 so that the waterstop plate 1 is brought into contact with the floor surface 109. When the waterstop plate body 2 is lowered to 109 and lifted as it is, the waterstop plate main body 2 is placed in a state of being placed in contact with the opening end edge 111 by inclining the upper portion (see FIG. 6). .. Since the tip of the rocking piece 3 of the waterstop main body 2 is oriented and protrudes downward from the building outer side 107 and is in contact with the floor surface 109, the waterstop plate main body 2 is shaken without applying an external force. With the tip of the moving piece 3 as a fulcrum, it naturally inclines toward the building opening 101. Further, since the waterstop plate main body 2 is supported from the floor surface 109 to the P1 side by the rocking piece 3, a distance S1 is generated between the lower end surface of the waterstop plate main body 2 and the floor surface 109. become.

Subsequently, the waterstop plate main body 2 is pressed in the direction P2 by using the pressing mechanism 103 provided in the waterstop plate 1 (this pressing action may be performed by the own weight of the waterstop plate 1 as described above. However, in this description, the following description will be given when the pressing mechanism 103 is used.) As described above, as the pressing mechanism 103, for example, the mechanism disclosed in Japanese Patent Application Laid-Open No. 2017-160693 can be adopted. The pressing portion abuts on the inner wall of the opening in conjunction with the rotation of the shaft, and when the lever is further tilted, the rotating shaft that rotates and moves the shaft core rotates, and as a result, the pressing portion abuts and presses against the inner wall of the opening. , The waterstop main body 2 can be pressed toward the direction P2.

Since the waterstop plate main body 2 is pressed toward the direction P2 by the pressing mechanism 103, the distance S1 between the lower end surface of the waterstop plate main body 2 and the floor surface 109 becomes small. Along with this, the rod portion 21 of the main body portion 5 constituting the swing piece 3 is pressed against the floor surface 109 from the direction P1 side and slides into the hollow portion 23 of the cylinder portion 19 while compressing the coil spring 9. The length reduction mechanism begins to work.

The stress of the coil spring 9 is increased by the compression, and a repulsive force for pressing the rod portion 21 to the outside of the cylinder portion 19 is generated (repulsive elasticity mechanism). The repulsive force is oriented diagonally downward along the axial direction of the rocking piece 3 and diagonally upward on the building opening 101 side, but the tip end side of the rocking piece 3 is supported on the floor surface 109 without slipping. Since it is fixed or pressed downward by the pressing mechanism 103, the repulsive force in the diagonal direction acts in the direction of urging the waterstop main body 2 toward the building opening 101 (main urging action). At the same time, the pressing mechanism 103 also lowers the connection position between the waterstop body 2 and the swing piece 3 (in other words, the position of the hinge 17), changes the angle of the swing piece 3, and repels the swing piece 3. The orientation angle of the force is tilted toward the building opening 101 side, and the action of urging the waterstop main body 2 toward the building opening 101 side can be more effectively exerted (secondary urging action).

More specifically, the rocking piece 3 opens the building along its own axis as described above by the pressing force H1 that presses the waterstop main body 2 exerted by the pressing mechanism 103 toward the direction P2. A repulsive force is exerted diagonally upward on the 101 side, and the repulsive force is generally composed of an upward component force H2 and a lateral component force H3 (that is, an upward component force H2 and a lateral component force H3). It is divided into.).

Since the upward component force H2 by the rocking piece 3 is killed by facing the pressing force H1 of the pressing mechanism 103, the lateral component force H3 urges the waterstop main body 2 toward the building opening 101 (). Main urging action). Therefore, regarding the relationship between the pressing force H1 (or the own weight of the waterstop plate 1) of the pressing mechanism 103 and the repulsive force of the repulsive elasticity mechanism, the pressing force H1 (or the own weight of the waterstop plate 1) is higher than the repulsive force. It may be designed so as to be the same as or larger than the directional component force H2.

Further, as described above, the rocking piece 3 moves downward at the connection position with the waterstop main body 2 due to the pressing force H1, and the inclination angle with the floor surface 109 becomes smaller (approaches horizontal). The component force ratio to the lateral component force H3 becomes large, and the waterstop main body 2 can be urged more strongly toward the building opening 101 side (secondary urging action).

As another embodiment relating to the repulsive elasticity mechanism of the rocking piece 3, a combination of a rail body formed on the rocking piece connecting surface 27 of the waterstop main body 2 and a spring provided on the rail body is used. As described above, it is more desirable that the repulsive elasticity mechanism is configured in the axial direction of the rocking piece 3 because the above-mentioned main urging action is exhibited but the above-mentioned secondary urging action is not exerted by the above configuration. I understand.

Further, since the rocking piece 3 maintains the contact with the floor surface 109 even after the main waterstop plate 1 is installed in the building opening 101, the waterstop main body 2 is attached to the building opening side 101. It is possible to continuously improve the water stoppage during use and preferably prevent water leakage.

Although the typical embodiment of the waterstop plate 1 in the present embodiment has been described above with reference to the drawings, the present invention is not limited to these embodiments, and the description of the scope of claims is described. There are other modifications and improvements to the extent that they do not deviate from the spirit and teachings, all of which are within the technical scope of the invention.

5. Other aspects of the rocking piece The rocking piece used in the present invention has the following swing pieces, in addition to disposing one or more substantially rod-shaped rocking pieces 3 on the waterstop main body 2 as in the above embodiment. Such an embodiment may be used.

Other swinging pieces will be described with reference to FIGS. 8A and 8B. 8 (a) and 8 (b) are views showing the mode of other rocking pieces, and FIG. 8A is a rocking piece connecting body 203 formed by connecting a plurality of rocking pieces 3. 8 (b) is a front view showing a substantially long swing piece 303.

As shown in FIG. 8A, a plurality of rocking pieces 3 are arranged in parallel at predetermined intervals, and the rocking pieces 3 are connected by a long connecting material 15 (a plurality of rocking pieces 3 are connected to each other). It is desirable that the portion connected by 15 is above the length reduction mechanism), and the swing piece connecting body 203 integrally configured may be used. Further, as shown in FIG. 8B, a long and thin box-shaped cylinder portion 319 and a plate-shaped rod portion 321 that can be fitted in the box-shaped cylinder portion 319 are long and long. It may be a rocking piece 303. As the anti-slip tool 311, a small one may be arranged at the lower end of the rod portion 321 at a predetermined interval, or an anti-slip tool 311 having substantially the same length as the rod portion 321 may be arranged at the lower end of the rod portion 321. You may.

In the embodiment such as the swing piece connecting body 203 and the long swing piece 303, the swing variation of each swing piece that occurs when a plurality of swing pieces are arranged on the waterstop main body 2 Can be suppressed, and the rocking piece can be more reliably brought into contact with the floor surface 109.

For the swing piece such as the swing piece 3, the swing piece connecting body 203, and the long swing piece 303 described above, the tip side is flipped up to the upper side of the waterstop plate main body 2, and the waterstop plate 1 It may be easily stored and stored and may look good. In that case, it is also preferable to form a swinging piece gripping portion (not shown) on the upper side of the waterstop main body 2.

Further, the mass (self-weight) of the waterstop 1 is an upward component of the repulsive force possessed by the repulsive elastic mechanism of the rocking piece (rocking piece 3, rocking piece connecting body 203, long rocking piece 303, etc.). If it is set smaller than H2, even if the waterstop plate 1 is stored and stored, even if it is leaned against a wall surface or the like, the waterstop packing 13 provided on the waterstop plate 1 (particularly, the waterstop plate main body 2). It is suitable because the waterproof packing 13) formed on the bottom surface is not deformed or deteriorated due to an unnecessary pressure being applied to the waterproof packing 13B).

Further, as shown in FIGS. 9 (a) and 9 (b), a bendable portion 29 is formed in the intermediate region of the rod portion 21, and a substantially straight rod portion 21 is formed by the bend portion 29 during storage and storage. If it is made bendable, the waterproof packing 13B can be protected more effectively. It is desirable that the bending angle at the bending portion 29 is substantially parallel to the bottom surface of the waterstop main body 2.

A straight holding mechanism that can provide a swing stopper (not shown) that holds the swing of the swing piece 3 in a substantially vertical or slightly tilted state, or can hold the swing portion 29 in a substantially straight shape when bending is not required. If (not shown) is provided, the waterstop plate 1 can be stored and stored more stably. 9 (a) and 9 (b) are views showing a swing piece provided with a bent portion 29, and FIG. 9 (a) is a side view showing a state in which the rod portion 21 is extended, and FIG. (B) is a side view showing a state in which the rod portion 21 is bent by the bent portion 29.

The waterstop in the present embodiment can reliably prevent the ingress of water from the outside with less concern and concern about water leakage while reducing the number of steps for installing the waterstop.
