Description

The present invention relates to a building flood prevention and/or cold air inflow prevention device that prevents water from entering through the ventilation layer between the foundation and base of a building and/or the inflow of cold air, a building equipped with the device, and a building flood prevention and/or cold air inflow prevention method.

Ventilation under floors and on the inside of exterior walls is an effective way to prevent moisture in buildings, and is widely adopted as a construction method for wooden buildings.
This ventilation is achieved by air moving in and out of the foundation flashing.
Recently, it has become common to lay foundation gasket over the entire foundation, place a foundation on top of the gasket, and use the space between the foundations as a ventilation layer through which air can be let in and out from under the floor to achieve underfloor ventilation.
When using this ventilation method in which air passes through the foundation drainage, it is necessary to take anti-rodent measures to prevent small animals such as mice from entering the building through the ventilation layer. There are three main types of such measures:
The first is to install a mouse-proof foundation gutter with ventilation holes. The second is to install a mouse-proof member with ventilation holes immediately adjacent to the outside of the ventilation layer. The third is to lay a mouse-proof foundation packing with ventilation holes.

However, all of these rodent-proof ventilation holes provide a route for water from floods and cold air in winter to enter the building, and water can enter under the floor through the ventilation layer between the foundation and the base and into the building.
Technologies proposed to prevent water from seeping in through this ventilation layer include a "foundation drain that blocks the ventilation holes with a floating member (Patent Document 1)" and a "water seepage blocking device equipped with a water-absorbing polymer around the foundation (Patent Document 2)."
As a measure to prevent cold air from entering through the ventilation layer, a "water-repellent material with shutters (Patent Document 3)" has been proposed.

However, this building flood prevention device requires family members to manually walk around the entire perimeter of the building and secure each waterproof member in place to block each ventilation hole.
Therefore, this manual work will take a certain amount of time, and in areas where wood decks or air conditioner outdoor units are installed, the wood decks etc. will get in the way, which may make the work even more time-consuming.

Patent No. 6534605 JP 2021-183760 A Patent No. 4755775

The object of the present invention is to provide a water ingress prevention device for a building and/or cold air ingress prevention device that can be installed manually or electrically at one or more locations on the building to block ventilation holes in foundation drains, etc., and that can be used simultaneously to prevent water ingress and/or cold air ingress through the ventilation layer between the foundation and the base.

In order to solve the above problems, one aspect of the present invention is a water and cold air intrusion prevention device used in a building equipped with a base drain with mouse-proof ventilation holes to prevent water intrusion or cold air inflow from the ventilation layer between the foundation and the foundation, and includes a prevention member for blocking the multiple ventilation holes of the base drain, a fixing member for movably holding the prevention member between an open position that opens the multiple ventilation holes and a closed position that blocks the multiple ventilation holes, a plurality of connecting support fluids connected to the prevention member or the fixing member and extending through the ventilation layer to the inside of the building, and a connector connected to the multiple connecting support fluids inside the building and receiving power to move the prevention member from the open position to the closed position. This makes it possible to prevent water intrusion or cold air inflow from the ventilation layer between the foundation and the foundation.

Another aspect of the present invention is a water and cold air intrusion prevention device used in a building in which a rat-proof member with ventilation holes is installed, for preventing water intrusion or cold air intrusion from the ventilation layer between the foundation and the base, and includes a prevention member for blocking the multiple ventilation holes of the rat-proof member, multiple connecting support fluids connected to the prevention member and extending into the building through the ventilation holes of the rat-proof member and the ventilation layer, and a connector connected to the multiple connecting support fluids inside the building and receiving power to move the prevention member from an open position that opens the multiple ventilation holes to a closed position that blocks the multiple ventilation holes. This makes it possible to prevent water intrusion or cold air intrusion from the ventilation layer between the foundation and the base.

Another aspect of the water and cold air intrusion prevention device of the present invention is a water and cold air intrusion prevention device used in a building in which a foundation packing with a rat-proof ventilation hole is installed, for preventing water intrusion or cold air inflow from the ventilation layer between the foundation and the foundation, and includes a prevention member for blocking the multiple ventilation holes of the foundation packing, multiple connecting support fluids connected to the prevention member and extending into the building through the ventilation holes of the foundation packing, and a connector connected to the multiple connecting support fluids inside the building and receiving power to move the prevention member from an open position that opens the multiple ventilation holes to a closed position that blocks the multiple ventilation holes. This makes it possible to prevent water intrusion or cold air inflow from the ventilation layer between the foundation and the foundation.

In the above aspect, the device may further include a moving device that supplies the power to the connecting body for moving the prevention member from the open position to the closed position. This makes it possible to move the prevention member from the open position to the closed position using the moving device.

In the above aspect, the device may further include a release body connected to the prevention member and receiving power to move the prevention member from the closed position to the open position, and a release actuator that supplies the power to the release body to move the prevention member from the closed position to the open position.

In the above aspect, the fixing member may include a bolt that is inserted into the ventilation hole and passes through the prevention member, and a nut that is attached to the bolt, and the head of the bolt and the nut may sandwich the base drain and the prevention member. This makes it possible to easily fix the prevention member to the base drain.

In the above aspect, the head of the bolt may have a shape that allows it to be inserted into the ventilation hole at a first rotation angle around the axis, but does not allow it to be inserted into the ventilation hole at a second rotation angle that is 90 degrees different from the first rotation angle. This makes it possible to easily fix the prevention member to the base drain.

In the above aspect, the plurality of ventilation holes extend in a first direction and are aligned in a second direction perpendicular to the first direction, and among the plurality of ventilation holes, some ventilation holes into which the bolt is inserted may be longer in the first direction than the other ventilation holes, and the bolt may move the some ventilation holes in the first direction as the preventing member moves from the open position to the closed position. This makes it possible to move the preventing member between the open position and the closed position by utilizing the some ventilation holes formed long in the first direction.

In the above aspect, a pin having a through hole is further provided, which is inserted from the outside and fixed to the vertical wall of the base drain, and the connecting support fluid may be wire-shaped and connected to the prevention member or the fixing member through the through hole of the pin. This makes it possible to adjust the direction in which the connecting support fluid moves the prevention member.

In the above aspect, the preventing member may be configured to be retractable, and may further include a storage body for storing the retracted preventing member, and a pull-out body connected to the preventing member and receiving power to pull the preventing member from the storage body along the surface on which the ventilation hole is formed. In this way, it is possible to move the preventing member to the blocking position by pulling out the retracted preventing member.

Hereinafter, the embodiment for carrying out the present invention will be described. However, the embodiment described below and the technical scope of the present invention are not limited to the embodiment and drawings below, and existing technologies and the like are used to carry out the present invention.
In addition, in the illustration, some parts are shown as schematic diagrams with gaps between the parts to make the arrangement of each part easier to understand, but in reality, the parts are in close contact with each other in areas where watertightness needs to be ensured.

First, what is common to aspects 1 to 7 will be described.
The prevention member 1 is intended to prevent water and cold air from entering the building through the ventilation layer between the foundation and the base via each ventilation hole, and is therefore made of metal, resin or other material that is weather-resistant and durable, and in particular has water resistance and water pressure resistance when flooded.
The shape may be a flat plate having reinforcing portions such as an L-shape at either or both ends.
In addition, it is advisable to attach a water-absorbent sheet, water-absorbent sponge, packing, etc. to the surface of the prevention member 1 that comes into contact with the ventilation hole 6a, etc., in order to improve watertightness.

The fixing member 2 is intended to fix the prevention member 1 in a position that blocks each ventilation hole to prevent the intrusion of water and cold air, and is therefore made of metal, resin or other material that has weather resistance, durability and water resistance, just like the prevention member 1.
The shape will vary depending on the embodiment, but for example, in embodiment 1, the shape is not limited as long as it has a hook or bolt with an L-shaped, T-shaped, or round dish-shaped head, wire-shaped, or frame-shaped, and has the function of securely fixing the prevention member 1 to the base drain 6.

The points common to the first to fourth aspects will now be described.
The connecting support member 3 is interposed between the fixing member 2 and the connector 4 to connect them together (however, in embodiment 1, the prevention member 1 and the connector 4 may be directly connected), and is therefore made of weather-resistant, durable, water-resistant metal, resin, or other material. The shape of the connecting support member 3 may be wire-like, rod-like, etc., depending on the embodiment.

The connecting body 4 is intended to move the prevention member 1 to a state that prevents water from entering or cold air from entering by, for example, winding it up around a moving device 5 installed at one or several locations via a plurality of connecting support members 3 and fixing members 2, and is therefore made of metal, resin, or other material that is weather-resistant, durable, and water-resistant.
Since the material is moved by the moving device 5 using a winding type, a feed roller type, or the like, the material is shaped in a wire form which is easily adapted to the winding type, or in a rod or flat form which is easily adapted to the feed type, or the material may be a combination of these shapes, and there is no limitation on the shape.

The moving device 5 is a device that moves the connecting body 4 toward the moving device 5 by winding up the connecting body 4 using a winding method or the like, and moves the prevention member 1 to a position where it blocks the ventilation hole.
Specifically, it is installed in one or several places on a building depending on the shape of the building, and is moved by manually or electrically winding the connecting body 4. For example, if the connecting body 4 is wire-shaped, it is called a wire winding machine. The connecting body 4 may also be a belt or a chain, and the moving device 5 is a device that combines a motor, a limit switch, a reducer, a driven pulley, a belt, etc., and there is no limitation on the technical method adopted for the device.
In addition, the moving device 5 may have a function of moving the connecting body 4 in the reverse direction in order to return the prevention member 1 from a position blocking the ventilation hole to a position where it does not block the ventilation hole.
In addition, operation can be manual or electric, but even if it is electric, it is preferable that it also has a function for manual winding in case of a power outage, etc.

The above components may be arranged inside the building as shown in Figure 1, or, although not shown, may be arranged in whole or in part outside the building, such as along the perimeter of foundation A or along the foundation drainage C.

Each aspect of the embodiment will be described in turn.
The first aspect is a device for preventing water ingress, etc., in a base drain 6 with a rodent-proof ventilation hole.
The building's foundation gutter C・6 is installed around almost the entire perimeter of the building except for the entrance etc. to prevent rainwater and splash water from coming into contact with the building's foundation B etc. and to take ventilation efficiency into consideration (see Figure 1).
The ventilation holes 6a of the mouse-proof base drain 6 with ventilation holes, which is a type of base drain C, are generally rectangular in shape and have a long side of about 1 centimeter and a short side of about 5 millimeters.
In the first embodiment of the first aspect, one of the features is that the long side of the ventilation hole 6b to which the prevention member 1 is fixed by the fixing member 2 such as a hook is made longer toward the building side, as shown in Fig. 2. In the case of an existing base drainage 6 with a rat-proof ventilation hole, the ventilation hole 6a to which the prevention member 1 is fixed is machined with a hacksaw or the like while it is installed, toward the building side to a shape that can accommodate a hook or the like, to form the ventilation hole 6b to which the prevention member 1 is fixed.
As a second embodiment of the first aspect, instead of the first embodiment (a fixing method using a fixing member 2 such as a hook), a fixing method is provided in which the prevention member 1 is enclosed in an outer frame-shaped fixing member 2 provided at the bottom of the foundation drip edge and fixed, as shown in Fig. 3. This is a method in which the prevention member 1 is stored on the building side of the outer frame-shaped fixing member 2 so that the prevention member 1 does not block the ventilation hole 6a in peacetime.
In this embodiment, the outer frame-shaped fixing member 2 is made of a durable and weather-resistant material and is formed to fit the size of the base drain. The bottom wall is open to allow ventilation except for the part that supports the prevention member 1 to prevent it from falling. Air flows in and out through the ventilation holes 6a and 6b of the base drain 6 from the opening.
Conventional mouse-proof base drains 6 with ventilation holes do not have this shape and function (corresponding to embodiments 1 and 2). Therefore, in existing base drains 6, some of the ventilation holes 6a are enlarged to form 6b, or an outer frame-shaped fixing member 2 is fixed by screws or the like.
In the case of a new building, the ventilation hole 6b is either shaped as described above in advance, or a base drip-water outlet 6 having a shape that has the function of the outer frame-shaped fixing member 2 is manufactured and used with this device.

In either of the above two embodiments, the prevention member 1 is fixed in peacetime to the outside of the lower part of the foundation drip edge 6 in a state where it does not block the ventilation hole 6a (toward the building) (see Figures 2 and 4).
In both of the above-mentioned embodiments 1 and 2, when it is necessary to prevent flooding or the inflow of cold air, as shown in FIG. 3, the prevention member 1 is moved by a manually or electrically operated moving device 5 via the connecting body 4 and the connecting support fluid 3 to a position where it blocks the ventilation hole 6a, and is fixed in that position to prevent flooding, etc.
The material and thickness of the prevention member 1 may be a metal convex, resin, wooden plywood, or the like having a thickness of about 0.1 mm or more, and there is no restriction on the material or thickness.
The width must be such that it is possible to close the rodent-proof ventilation hole 6a.
In terms of length, if the material cannot be rolled up, a length of about 2 to 3 meters, like general building materials, is good for easy handling during transportation, etc. However, if the material can be rolled up, such as in a convex shape, a longer length is better, as this will reduce the number of joints, improve watertightness, and improve the ability to prevent water intrusion, etc.

The fixing member 2 is for adhering the prevention member 1 to the base drip edge 6 and fixing it in a state where airtightness, particularly watertightness, is ensured.
As mentioned above, the fixing methods are roughly divided into two types. One (embodiment 1) is a type in which a part of the ventilation hole 6a is enlarged on the building side to form a ventilation hole 6b, and the prevention member 1 fixed to the same part by a fixing member 2 such as a hook is stored on the building side during normal times.
In this case, when the fixing member 2 is hook- or bolt-shaped, when installing this device on an existing base drain 6, the head of the hook or the like must be shaped so that it can be inserted into the base drain 6 through the ventilation hole 6b and must also be shaped so that it will not fall out of the ventilation hole 6b, so a hook, bolt, or the like with an L- or T-shaped head is used. Note that even if a bolt or the like with a dish-shaped or other circular head is used, it is possible to pass a bolt of a size that can pass through the ventilation hole 6b and use it in combination with a circular washer or the like with a diameter larger than the short side of the ventilation hole 6b inside the base drain 6, but this is inefficient in terms of work efficiency.
In the case of a new building, it is possible to fix the prevention member 1 by inserting a hook or a flat head screw with a circular bolt head into the foundation drain ventilation hole 6b, so there is no limitation on the shape of the head of the hook, etc., as long as it is larger than the short side of the ventilation hole 6b and will not fall out of the ventilation hole 6b.
Furthermore, when the fixing member 2 is made in the form of a wire, the upper end is passed through the ventilation hole 6b, a circular washer is inserted, and the wire is secured with a sleeve or the like to prevent the wire from falling out of the ventilation hole 6b. On the other hand, the lower end is passed through the prevention member 1 and secured with an existing technique such as a sleeve fastener.
Another method (embodiment 2) of fixing the prevention member 1 to the base drain 6 is to provide an outer frame-shaped fixing member 2 that can encase the prevention member 1 at the bottom of the base drain 6.
In the case of an existing base drain 6, the outer frame-shaped fixing member 2 formed to match the size of the base drain is fixed to the bottom of the base drain 6 by screws, etc. In the case of a new construction, the outer frame-shaped fixing member 2 may be fixed to the base drain 6 in this manner, or a base drain 6 having the functions of the outer frame-shaped fixing member 2 may be manufactured and used.

The connecting support member 3 is interposed between the fixing member 2 or the prevention member 1 and the connector 4 to connect them, and when the prevention member 1 is made into a hook shape or the like, it is interposed between the fixing member 2, which is like a hook shape, and the connector 4 to fix and connect them. When the fixing member 2 is made into an outer frame shape, the prevention member 1 and the connector 4 may be directly fixed and connected. The material is a weather-resistant and durable material such as metal, and the shape may be a wire, bolt, rod, or the like.
The connecting support pin 3 fixed to the prevention member 1 is fixed to the prevention member 1 through the through hole of the pin 3a (the pin has a through hole in the axis of the inner part of the base underside 6) which penetrates and is fixed from the outside to the vertical wall of the base underside 6, as shown in Fig. 3. By passing the connecting support pin 3 through the through hole of the pin 3a, the connecting support pin 3 moves toward the inside of the building, and the prevention member 1 moves horizontally toward the outside of the building to block the ventilation holes 6a and 6b.
As shown in Figures 4 (4-1 and 4-2), the connecting support member 3 fixed to the fixing member 2 may be aligned along the outer wall of the foundation drain 6, and inserted into the foundation drain 6 through a pin 3b (a pin to ensure watertightness) inserted into the vertical wall, and then passed across the ventilation layer D between the foundation and the base, and connected to the connector 4. As the connecting support member 3 moves toward the inside of the building, the prevention member 1 may move horizontally toward the outside of the building.

The connector 4 is for connecting a plurality of fixing members 2 or a plurality of connecting support members 3 fixed to the prevention members 1. In short, the connector 4 is for moving the connected prevention members 1 to a state where the ventilation holes 6a (6b) are closed by the operation of the moving device 5 installed at one or several positions.
For example, when the prevention member 1 is fixed to the base drain 6 at intervals of 1 meter using the hook-shaped fixing member 2 of embodiment 1, the connecting members 3 of the multiple wires fixed to the fixing member 2 can each be fixed to the wire connector 4, and the wire connector 4 can be pulled in by winding it up or the like using a mobile device 5, thereby blocking the ventilation holes 6a and 6b with the prevention member 1.
Furthermore, when the fixing member 2 of embodiment 2 is an outer frame-shaped fixing member 2, the connecting support members 3 are fixed to the prevention member 1 at intervals of 1 meter, and the connecting support members 3 are fixed to the connecting body 4. As described above, the connecting body 4 is pulled toward the mobile device 5, whereby the ventilation hole 6a can be blocked by the prevention member 1.

The moving device 5 is adapted to pull the connecting body 4 by winding up or unwinding one end of the connecting body 4, thereby moving the prevention member 1 to a position where it blocks the ventilation hole 6a (6b).
Operation shall be by manual winding and unwinding machines, or by an electric winding machine consisting of a motor, control panel, switches, etc.

The second aspect will now be described.
This is a device for preventing water from seeping in through the ventilation layer D when a rat-proof member 7 is installed on the base B by nailing it to the base B immediately outside the ventilation layer D between the base and the foundation, using a base drip C without rat-proof ventilation holes. This rat-proof member 7 is often used with a rat-proof foundation packing 12 with ventilation holes installed over the entire base, or a foundation packing 12a without ventilation holes installed partially on the base, so as shown in Figure 5, the connecting support member 3 and the release body 14 can be installed by penetrating the inside of the rat-proof foundation packing 12 with ventilation holes, or on the base (space) where the foundation packing 12a without ventilation holes is not installed.
In normal times, the prevention member 1 is hung in a position that contacts the outer periphery of the foundation A below the rat-proof member 7. When closing the ventilation hole of the rat-proof member 7, the moving device 5 is operated to move the prevention member 1 connected to the connecting support member 3 or the connector 4 to the position of the ventilation hole, and the prevention member 1 is fixed in a state of close contact with the outside of the rat-proof member 7 by pulling it inward from the building.
The material, thickness, width, and length are the same as in embodiment 1.

The fixing member 2 is preferably wire-shaped. This is because, in the case of the embodiment 2, unlike the embodiment 1, in the normal state when the prevention member 1 does not block the ventilation hole of the rat-proof member 7, there is no space to fix the prevention member 1 to the rat-proof member 7, so the prevention member 1 is hung down as shown in Fig. 5-2.
For this reason, the wire-like member is deformable, and the prevention member 1 has good mobility when it is lifted from a state in which it is suspended close to the foundation A to a state in which the ventilation hole is blocked.
In addition, the prevention member 1 may be placed on a shelf-like storage portion provided on the outer periphery of the base A.

The connecting fluid supply 3, the connecting body 4, and the moving device 5 are the same as those in the first embodiment.
The connecting support member 3 may be an extension of the wire or the like of the fixing member 2.

The third aspect will now be described.
This is a device for preventing water ingress, etc., when a building uses a foundation gasket 12 with rat-proof ventilation holes, but the foundation drain C is not equipped with rat-proof ventilation holes 6a, and no rat-proof members 7 are installed.
As shown in Figure 6-2, when the prevention member 1 is not blocking the ventilation holes of the mouse-proof foundation packing 12 with ventilation holes, it is located at the outer end of the foundation A close to the outside of the base B. However, if the outer end is too narrow for the prevention member 1 to rest on the outer end of the foundation A, the prevention member 1 is suspended at a position in contact with the outer periphery of the foundation A, as in the second embodiment.
Then, as shown in Figure 6-1, when flooding is predicted, etc., the mobile device 5 is operated manually or electrically to pull the prevention member 1 connected to the connecting body 4 and the connecting support member 3 toward the inside of the building and fix it tightly to the ventilation hole, and the fixed state of the prevention member 1 is maintained by the pulling force, thereby preventing flooding, etc.
The thickness and material are the same as in the first embodiment.
The width is such that it is capable of blocking the ventilation holes of the rodent-proof ventilation hole-equipped foundation gasket 12, and may be adjusted to be slightly narrower than the distance between the foundation A and base B (ventilation layer D) so that it can be smoothly inserted and removed.
The length is the same as in embodiment 1.

The fixing member 2 has a wire-like shape which is deformable and therefore easy to handle during installation and operation, but it may also be in the form of a bolt, hook, or the like.
For example, if it is in the form of a wire, one end may pass through the prevention member 1 and be fixed at the end by a sleeve fastener or the like, and the other end may be connected and fixed to the connecting support member 3 by a sleeve.
When the prevention member 1 is to be used to block the ventilation hole, the moving device 5 is operated to move the connecting body 4 and the connecting support member 3 toward the moving device 5, and the prevention member 1 is fixed in a tightly contacted state against the outside of the foundation gasket 12 by pulling it toward the foundation gasket 12 (inside the building).
It is also possible to connect directly to the connector 4 without using the connecting support fluid 3. In this case, the end not fixed to the prevention member 1 is passed through the ventilation hole of the base packing 12 and fixed to the connector 4 with a sleeve fastener or the like.

The connecting fluid 3, the connecting body 4, and the moving device 5 are the same as in embodiment 1.

In existing buildings, it is easy to install the ventilation holes in the existing foundation packing 12 by penetrating them with fixing members 2 such as wires, or connecting support members 3, but in the case of a newly constructed building, if a support groove 16 into which the fixing members 2 etc. can be placed is provided at the top of foundation A and the bottom of base B, and the fixing members 2 etc. are made to cross the ventilation layer D (above foundation A) using said groove 16, no load will be generated due to friction etc. of the fixing members 2 etc. inside the foundation packing 12, which will prevent internal damage to the foundation packing 12.
Furthermore, if the transverse angle of the groove 16 is made acute toward the mobile equipment 5, the frictional resistance to the fixing members 2, etc. within the tributary groove 16 of the foundation A and base B when the prevention member 1 is pulled toward the inside of the building is reduced, which has the advantage of allowing the prevention member 1 to move smoothly.
Since the fixing member 2 or the connecting support 3 is installed in the ventilation hole of the foundation packing 12 or in the support groove 16 above and below the foundation packing 12, the connecting body 4 is easily installed along the foundation B inside the building (under the floor). However, the connecting support 3, the connecting body 4, and the mobile device 5 may be installed outside the building (on the outer periphery of the foundation A, etc.).
Also, for example, in a portion where a wooden deck or the like is installed, one end of the fixing member 2 or the connecting support member 3 can be brought outside the building, and passed under the floor of the wooden deck with the connecting body 4, and extended to the outside of the wooden deck, where the connecting body 4 can be pulled in by the moving device 5, so that the ventilation hole portion can be easily closed with the prevention member 1. However, in this case, the joining with the connecting body 4 can be omitted and the connecting support member 3 can be pulled in directly.

The fourth aspect will now be described.
This is an embodiment that applies to embodiment 1 of aspect 1.
In the case where a prevention member 1 is fixed in a suspended state by a hook-shaped fixing member 2 inserted into an enlarged ventilation hole 6b which is a part of a ventilation hole 6a of a mouse-proof foundation gutter 6 with ventilation holes of an existing building, the fixing member 2 is a T-shaped hook 11 or a bolt 11 with a T-shaped head.
Because the ventilation hole 6b has a larger long side than the ventilation hole 6a (long side about 1 cm x short side about 5 mm), a round-headed hook or bolt such as a flat head screw with a diameter of about 7 mm or more cannot penetrate the ventilation hole 6b in the existing base drain 6. Also, a hook or the like with an L-shaped head smaller than the rectangular shape of the ventilation hole 6b will penetrate the ventilation hole 6b, but after fixing, the L-shaped part may rotate and come out of the ventilation hole 6b.
In this regard, if a T-shaped head hook 11 and bolt 11 are used, one end of the T-shaped head will hit the inside of the vertical wall of the base drip edge 6, reducing the risk of the head slipping out of the ventilation hole 6b.
The T-shaped head hook 11 and bolt 11 are special, with a thickness of about 4 millimeters, but their shapes are appropriate for applying this device to an existing rodent-proof foundation drain 6 with ventilation holes.
In the case of a new building, even if the hook or bolt has a circular head such as a dish-shaped head, it can be passed through the ventilation hole 6b from the inside of the foundation drip 6 before installation and the prevention member 1 can be fixed in place. Also, a circular head with an outer diameter larger than the short side of the ventilation hole 6b will not slip out of the ventilation hole 6b, but this does not prevent the use of the hook 11 and bolt 11 with a T-shaped head.

Aspect 5 will now be described.
This embodiment applies to the ventilation holes described in aspects 1 to 3.
Its feature is that the prevention member 1 is made of metal, resin, or the like and can be wound up in a convex shape.
Since the prevention member 1 can be rolled up, it can be stored in a tape measure case-like storage body 8, like a convex tape measure, during normal times when the ventilation holes (6a, etc.) are not blocked. This storage body 8 is provided adjacent to the base drip edge (C, 6).
When blocking a ventilation hole (6a, etc.) with the prevention member 1, the prevention member 1 is pulled out from the storage body 8 by a wire-like pull-out body 9 connected to the tip of the prevention member 1, and moved while being enclosed within the guide rail-like fixing member 2 to block the ventilation hole (6a, etc.).
In the case of the second embodiment of the first aspect, the shape of the fixing member 2 on the building side is reduced, that is, the shape is the part directly below the ventilation hole 6a of the mouse-proof ventilation hole-equipped base drip 6. The prevention member 1 having this shape moves along the outer periphery of the building inside the fixing member 2 in the shape of an outer frame, which has the properties of a guide rail.
In the embodiment of the second aspect, a guide rail 2a having a shape as shown in Fig. 8-1 (a schematic diagram of the mouse-proof member 7 as viewed from the inside of the building when installed) is provided on the outside of the mouse-proof member 7. The upper and lower ends of the prevention member 1 are then fixed so as to be enclosed by the guide rail, thereby blocking the ventilation hole.
In the embodiment of the third aspect, a guide rail 2a having a shape as shown in 8-1 in Fig. 8 is provided on the outside of the mouse-proof foundation packing 12 with ventilation holes as shown in 8-2. Then, as in the second aspect, the upper and lower ends of the prevention member 1 are fixed so as to be enclosed by the guide rail 2a, thereby blocking the ventilation holes.
In all of the embodiments, for existing buildings, the guide rail (outer frame) fixing member 2 (applicable to embodiment 1) or the guide rail 2a (applicable to embodiments 2 and 3) is molded from a durable, weather-resistant material such as metal or resin, and is later attached to the bottom of the foundation drip-line 6 in embodiment 1, to the outside of the rat-proof member 7 in embodiment 2, and to the outside of the foundation packing 12 in embodiment 3. For newly constructed buildings, the outer frame (guide rail) is installed below the foundation drip-line 6, and the guide rail (see FIG. 8-1) is installed on the outside of the rat-proof member 7 and on the outside of the foundation packing 12.
However, in both cases, the prevention member 1 is bent 90 degrees at the protruding corner and recessed corner, making it difficult to include it in the fixing member 2 of the guide rail (outer frame) at that part, and also difficult to move in the bent state at that part. Therefore, this embodiment is not suitable for application (installation) in buildings with short straight sections, but is suitable for application in rectangular buildings consisting of long straight sections of several meters.
The pull-out body 9 is pulled by a pull-out device 10 that is manually or electrically operated, for example by winding it up, to pull out the prevention member 1 from the storage body 8. When the pull-out device 10 is electrically operated, it may be combined with the water inundation depth sensor 13 of aspect 6, or it may be independently operable to be remotely operated by a smartphone or the like.
When storing the prevention member 1 in the storage body 8, if a stopper is provided on the storage body 8, the drawer device 10, etc., the stopper is released and the prevention member 1 is wound up and stored by the reaction of a spring provided inside the storage body 8.

An embodiment of aspect 6 will now be described.
In the embodiments of aspects 1 to 4, in order for the prevention member 1 to return from a state in which it prevents flooding, etc., to a state in which it does not block the ventilation holes (6a, etc.), family members or the like must go around the perimeter of the building and manually unblock each prevention member 1 to a state in which they do not block the ventilation holes, which is time-consuming and laborious.
This embodiment is a device for saving the labor and time required for removing the prevention members 1 one by one.
First, the release body 14 will be described. The material of this is a metal, a resin, or the like having durability and weather resistance, and it is composed of a part corresponding to the connector 4 and a part corresponding to the connecting support fluid 3. The part corresponding to the connector 4 is not limited to a wire-like, chain-like, or other shape, as with the connector 4. The part corresponding to the connecting support fluid 3 is not limited to a wire-like, or other shape when applied to the embodiment 1. However, when applied to the embodiments 2 and 3, since it is to push out the prevention member 1, it is made rod-like or flat. In addition, the tip portion is made to have a shape that contacts the prevention member 1 so that it can push the prevention member 1. In addition, the parts corresponding to the connector 4 and the connecting support fluid 3 have their connecting portions 14a movable. This movable type allows the part corresponding to the connecting support fluid 3 to change the arrangement angle in the release groove 17, and the tip portion can come out toward the outside of the building to push out the prevention member 1.
When applied to embodiment 2 of aspect 1, as shown in Fig. 3, the release body 14 is moved toward the inside of the building by a manually or electrically operated release operating device 15, and the prevention member 1 is pulled horizontally toward the inside of the building within the fixing member 2 at the bottom of the base water drain 6, so that the ventilation hole 6a is not blocked and placed in a normal state. Note that the same applies to embodiment 1 of aspect 1, although not shown.
In an embodiment of aspect 2, as shown in Figure 7, a release operating device 15 is used to push the prevention member 1 outward from the building using a rod-shaped, flat, etc. release body 14 installed in a trapezoidal release groove 17 provided at the bottom of base B or the top of foundation A, so that the prevention member 1 is suspended at a position in contact with the outer periphery of foundation A as shown in Figure 5-2.
In embodiment 3, as in embodiment 2, as shown in Figure 7, a release operating device 15 is used to push the prevention member 1 outward from the building using a release body 14, such as a rod or plate, installed in a release groove 17, so that the prevention member 1 is suspended from the upper outer end of the foundation A as shown in Figure 6-2, or at a position contacting the outer periphery of the foundation A as shown in Figure 5-2.
In this way, by activating the release operating device 15 installed in one or several locations, the prevention members 1 installed around almost the entire perimeter of the building can be easily released to a normal state in which they do not block the ventilation holes (6a, etc.).
In addition, before operating the release operating device 15, the moving device 5 is operated to release the force pulling the connecting body 4 so as to release the state in which the connecting support fluid 3 is pulling the prevention member 1 (blocking the ventilation hole (6a, etc.)).
As such, since it is important to adjust the operation of the release operating device 15 and the moving device 5, this device, in which the release body 14, the connecting support fluid 3, and the tension on the prevention member 1 by the connecting body 4 are adjusted to an optimal state, will be adopted in each building.
Furthermore, if the release operating device 15 and the moving device 5 are electrically operated, they can be remotely controlled using a smartphone, etc., and if they are connected to a humidity sensor, the ventilation holes (6a, etc.) can be appropriately opened and closed depending on the humidity level.

An embodiment of aspect 7 will now be described.
In any of the first to fifth embodiments, when the moving device 5 or the drawer device 10 is to be electrically operated, the operation switch must be turned on by a family member or the like.
However, flooding caused by heavy rain can reach a depth that exceeds the foundation in a very short period of time, and even in warm climates, the humidity can drop along with the temperature in winter, making it difficult for family members to notice certain levels of flood depth and humidity.
For this reason, a flood depth and humidity sensor 13 is installed near the building, and certain numerical values (flood depth, humidity) are set in the sensor 13 in advance. When the sensor 13 detects the numerical value, it transmits a signal. Upon receiving this signal, the electrically operated moving device 5 or pull-out device 10 turns on, and the prevention member 1 automatically blocks the ventilation holes (6a, etc.).
This device also makes it possible to always be prepared to prevent flooding, even in the event of a sudden rise in water level, particularly when no one is home or in the middle of the night.
If it is arranged to be linked with the release operating device 15 of aspect 6, the release of the prevention member 1 can also be performed automatically.

The eighth aspect will now be described.
This building is characterized by being equipped with a water ingress prevention device and having water ingress prevention measures implemented throughout the building to prevent water ingress through gaps in the exterior walls and other locations.
Specifically, this is a building that has block walls around it to prevent damage or loss of flood prevention equipment due to direct hits from floodwaters or drifting debris, and has gates that are designed to prevent water from passing through.

Furthermore, some conventional buildings have gaps between the base drain 6 with rat-proof ventilation holes and the foundation A. In such buildings, it is important to connect the foundation A and the base drain 6 with an L-shaped angle or the like to improve the watertightness of the two parts and take measures to prevent flooding.
In any embodiment, it is advisable to provide indicator lamps indoors and outdoors to indicate the state of the prevention member 1 (open or closed state of the ventilation hole) so that the state can be known.

Aspect 9 will now be described.
This is a method for preventing flooding of a building using a flood prevention device for the building.
The present invention is one of the disaster prevention measures, cold weather measures, and ultimately energy conservation and decarbonization measures.
In order to widely disseminate this device, the introduction of a subsidy or grant system, as well as preferential treatment for taking out building damage insurance if the device is installed, would be effective in disaster mitigation and disaster prevention measures, and ultimately in decarbonization measures.

The present invention is not limited to the above-described embodiment, and various modifications can be made to the material, fixing position, fixing method, arrangement, etc. of each member within the scope of the claims.
In addition, combining this invention with the applicant's previous technical proposals will be effective in achieving the objectives.
