Description

  The present invention can be completed within a short period of time without being dependent on specialists in typhoon forecasts, heavy rain flood warnings and tsunami warnings, river break warnings, etc. More particularly, the present invention relates to a flood prevention method for a house or the like having a shutter structure and a flood prevention sheet.

  Advances in forecasting technology and subdivision of forecasting unit areas have dramatically improved the accuracy of weather-related forecasts today. This means that you can afford to take time to take measures against anticipated disasters, as well as simply dodge.

  In the event of a disaster of a scale where the presence or absence of the house itself is a problem, such as the collapse or loss of the house etc., there is no room for personal countermeasures and should be evacuated to the designated evacuation site as soon as possible. is there. The most frequent flood damage and the most serious damage is underfloor inundation or on-floor inundation. The characteristics of damage during such a flood are rare in cases that are fatal to human lives, and most of the damage is due to the fact that household goods are immersed in mud and become unusable, impeding daily life for the time being.

  For example, in the case where a disaster due to strong winds is predicted with sufficient time, measures such as fixing unstable joinery, fixing items that are likely to scatter, and moving objects that are likely to collapse may be taken. it can. However, it is difficult to take specific measures when a flood disaster is predicted with sufficient time.

  Conventionally, in factories that handle special substances and public facilities that are designated as evacuation sites, examples include a water shutter or a water weir as an inundation prevention measure (see Patent Document 2 below), an example of storing sandbags There is. In addition, when building a new house such as a special unit method or panel method, an example in which the entire unit unit is covered with a waterproof sheet (see Patent Document 1 below), or a surface waterproof sheet is overlapped between adjacent panels. Such a proposal example (see Patent Document 3 below) can be seen.

  By the way, wooden houses are difficult to be watertight and have poor resistance to water damage.

  Moreover, inundation becomes a problem in the event of flood damage because it is a problem with the overall structure of the house including the vents, window frame openings, entrance openings, etc. provided in the concrete foundation, and from the gaps between the shutters, etc. It is also necessary to respond to intrusions.

  Further, even when a water shutter or a water weir is provided, it may not be effective unless the entire house is enclosed with a water shutter or the like. Further, even if the water leakage prevention performance between the panels connected to each other is sufficient, such performance is not obtained even at a connection portion (such as a gap portion of the shutter) between the panel and another member.

  In addition, regarding the window frame opening and the entrance opening, it is a big mistake to consider that there is no problem of flooding if the built sliding doors and doors are closed, in light of the actual flood damage situation. For example, the sliding door built in the window frame opening is fitted into the window frame rail via a pair of door wheels, and the portions other than the pair of door wheels are floating from the window frame rail. Although the labyrinth structure is adopted for the window frame rail and direct blow-through of the wind is prevented, the function of preventing flooding is poor. As for the entrance door, a minimum necessary gap for smoothly operating the hinge is set on the hinge mounting side, and it is difficult to completely prevent the flooding. This means that, in the case of what is called fire doors or water-proof doors, in addition to the turning operation by a hinge like a normal door, there is a complicated structure in which the door plate is moved in parallel and is in close contact with the sealed door frame. It is clear from being adopted.

The present invention aims to satisfy the following conditions, and prevents flooding of houses, etc. that can be constructed within a short time even by personnel other than construction contractors for existing houses, etc. in the event of a heavy rain flood warning, etc. The purpose is to provide a method of construction. In the description of the present invention, “houses and the like” is sufficient to protect against flood damage in addition to general residential houses, apartment houses, garages, warehouses, factories, stores (including convenience stores), and others. It includes buildings having a protective value, and also includes those having a shutter structure.
As a problem to be solved in order to achieve the above object, it is necessary to satisfy the condition that the member used in the flood prevention method according to the present invention is an item that can be stored in a general household. This is because there is not enough time to procure necessary parts in an emergency, and flooding disasters are a simultaneous and frequent threat to many houses in a specific area, making it impossible to procure necessary parts due to lack of goods. This is because of concern.

  It is necessary not to include construction contents that can only be constructed by specific specialists. In other words, satisfying the condition that the construction contents can be easily constructed within a short period of time even in the housekeeper. This is necessary in order to prevent the evacuation time when evacuating after construction from being eroded, and when a large number of construction requests are concentrated on a specific contractor against simultaneous simultaneous threats, the construction may not be in time. This is because it is easily assumed.

  It is necessary to satisfy the condition that an actual inundation preventing effect can be reliably obtained. This is an essential requirement of the present invention, and is a condition for advising a formal construction method that is not accompanied by an effect that emphasizes the appearance effect.

  After the danger of flooding the house has passed, it is necessary to satisfy the condition that the house can be easily restored to its original state. Houses, etc. are designed so that they can provide a predetermined housing ring in the completed state, so leaving the inundation-preventing construction state as it is will maintain the original performance of the house, including its useful life. This is because there is a risk of hindering the operation, and it is also necessary to avoid excessive costs for returning to the original state.

  That is, the object of the present invention is simple even for an amateur and can be completed within a short time without eroding the evacuation time. After the inundation prevention effect has been obtained and the danger of inundation has passed, the inundation prevention method can be used to easily return the house to its original state, and even ordinary households can store stock without incurring any special disadvantages. An object of the present invention is to provide a flood prevention sheet for a flood prevention method that can be stored.

  The inundation prevention method for a house or the like of the present invention is applied to the ground from the lower side of a shutter attached to a house such as a garage, using a flexible infiltration prevention sheet of an unspecified length having a predetermined width. The infiltration prevention sheet is supplied in a state along the position, and the infiltration prevention sheet is attached following the shutter. Further, the infiltration prevention sheet of the present invention is an infiltration prevention sheet that is supplied in a state along the position on the ground from the lower side of a shutter attached to a house such as a garage, and has a predetermined width of the infiltration prevention sheet. An adhesive means or an adhesive means for the shutter is provided on the upper side of the shutter. Here, in the present specification, the term “attachment” is defined as being good without using an adhesive means or an adhesion means by attaching. For example, it is attached by winding it around the outer periphery of a house, or it is attached by imitating a shutter using inundation such as rain water. Can be attached. On the other hand, an adhesive means or an adhesive means is defined as using an adhesive, an adhesive, a hook-and-loop fastener, or the like.

  In the above solution, the most important point is that the infiltration prevention sheet for preventing water intrusion is brought into close contact with the outer wall of the house or the shutter by the water pressure of the water to enter the house or the like. Adopts the idea of taking the water pressure as a threat to the other hand. This makes it very easy to attach the water-proof sheet to the outer walls and shutters of houses, etc., and makes the water-proof effect extremely reliable, preventing water from entering after water pressure is lost. The sheet removal operation is extremely easy. Therefore, it is necessary for the inundation prevention sheet to have a flexibility that can be made to follow the outer wall of a house using inundation such as flood.

In the present invention, it is preferable to provide an adhesive means or an adhesive means at the upper edge of the water-proof sheet, but this is not always necessary, and if the water-proof sheet can be arranged at a predetermined height along the shutter, rainwater or the like will be used later. It is possible to attach a water-prevention sheet following the shutter using water. Even if the shutter is closed downward, there is play (the width that moves by the clearance), so it is possible to accept rainwater and other inundation while moving it and fit it along the shutter (can be attached). In the case where there are columns, walls, blocks, etc. on the left and right of the shutter, it is preferable that the flood prevention sheets are included along with these. The sticking means or the sticking means may be attached to the shutter after sticking to the upper end side in the width direction of the water-proof sheet using an adhesive tape, double-sided tape, hook-and-loop fastener, etc. -It can be attached to the flood prevention sheet after it is attached to the pillar first. If the upper edge of the water-inhibiting sheet is bonded so as to extend over the concave and convex portions of the shutter, it is possible to prevent water from entering through the gap between the water-inhibiting sheet and the shutter. As the water immersion prevention sheet, it is preferable that the adhesion means or the adhesion means of the water immersion prevention sheet has a width interval over the uneven portion of the shutter. This is because the intrusion prevention sheet can be reliably attached using the uneven portions of the shutter, and water can be reliably prevented from entering. Moreover, it is preferable that a flood prevention sheet | seat is a transparent raw material and coloring is given to the upper end of the predetermined width | variety. Because it is transparent, you can check the drawer length with respect to the shutter, check the lower position of the shutter, and work while checking the lower position of the shutter, and its upper end side is colored, so you can check the height position of the transparent material and peel off This is because it will be easier. Further, the upper end in the width direction of the water-preventing sheet may be provided with an adhesive or the like slightly below the upper end without applying an adhesive or the like for peeling. In this case, the colored portion is preferably the upper end.
The infiltration prevention sheet is preferably larger than the inundation water level assumed in accordance with the local situation, but it is not always necessary, and water can be prevented from entering through the gap when the shutter is closed downward. This is because the upper end side of the inundation prevention sheet can be brought into close contact with the shutter by the water pressure of water that is about to enter a house or the like.
Here, “the inundation level assumed according to the local situation” is an objective in the case where it is assumed that the inundation disaster has occurred based on the analysis of the past flood damage situation in the area and the current flood control situation. Says the maximum water level expected. The “predetermined full width” for the flood prevention sheet refers to the total length in the width direction when the flood prevention sheet continuously formed with a constant width is rolled. About inundation prevention sheet "Unspecified length" is the length that can be individually adapted to the peripheral length of any of the houses, etc. This length is not particularly limited. The “predetermined width of the predetermined full width” of the flooding prevention sheet refers to a width dimension when a certain width is set within the predetermined full width.

The method for preventing inundation of a house or the like according to the present invention is to provide a blind plate if there is a clearance between the shutter and the outer wall or pillar of the house or an opening such as a vent on the outer wall of the house. After the construction, it is possible to adopt a construction method in which a flood prevention sheet is attached to the outer wall of a house or the like.
This solving means reduces the strength requirement for the water-inhibiting sheet, and thus it is possible to employ a thin soft water-inhibiting sheet that is highly adhesive to the surface shape of the foreign matter. That is, when the opening is simply covered with the water-inhibiting sheet, the water-inhibiting sheet is pushed into the opening by the water pressure, and as a result, the tensile strength limit may be exceeded and the material may break. In order to cope with such a situation, there are a countermeasure that adopts a higher-strength water-proof sheet and a countermeasure that closes the opening portion urgently. In the present invention, when the amount of use of the flood prevention sheet is large and expensive materials are used, the cost burden becomes a problem, the choice of the flood prevention sheet is limited, the flooding of the outer wall of a house or the like In consideration of the possibility that the adhesion of the prevention sheet may be reduced, a method is adopted in which a blind plate is applied to the opening to reduce the strength requirement for the infiltration sheet.

The present invention is characterized in that the upper end edge of the raised water-proof sheet is attached so as to extend over the concave and convex portions of the shutter. Here, the remaining part of the predetermined width of the flood prevention sheet is raised along the outer wall of the house, etc., and the upper edge of the raised flood prevention sheet is fixed to the outer wall of the house with an adhesive tape, and then the flood prevention sheet. It is preferable that an adhesive means or an adhesive means is used in combination at the entire length of the upper edge portion or at an important point.
According to the present invention, the attachment effect can be enhanced and the rainwater infiltration prevention effect can be enhanced by attaching the upper edge of the infiltration prevention sheet so as to extend over the concave and convex portions of the shutter. And by using together the said adhesion means or the adhesion | attachment means, the said attachment effect and the invasion prevention effect of rainwater can be heightened more. As a result, the width of the flood prevention sheet may be shorter than the flood water.

  The inundation prevention method for a house etc. of the present invention is an emergency opening that allows people to enter and exit when the entrance door no longer opens at a height exceeding the assumed inundation water level as an entrance door of the house etc. After the entrance door having the door is installed in advance, a method of attaching a flood prevention sheet to the entire periphery of the outer wall of a house or the like including the installed entrance door can be employed.

The present invention is characterized in that the flood prevention sheet is attached together with left and right outer walls and columns of the shutter. Here, grooves or irregularities are formed on the left and right outer walls / columns of the shutter to facilitate the attachment of the water-proof sheet, or the water-proof sheet is attached to the outer walls / columns having these in the first place. It is preferable. In addition, it is preferable to make a double structure in which the left and right outer walls / columns and the shutter are further attached with the water-proof sheet after the water-proof sheet is attached to the shutter.
According to the present invention, it is possible to prevent rainwater from entering between the left and right outer walls / columns of the shutter and the shutter, and to enhance the peeling prevention effect of the water-proof sheet.

The present invention is characterized in that a flood prevention sheet is attached to the entire circumference of the outer wall of a house such as a garage including the shutter.
According to the present invention, it is possible to prevent intrusion of rainwater from places other than the shutter by attaching the infiltration prevention sheet to the entire circumference of the outer wall of the house.

A convex portion corresponding to the concave portion of the shutter is formed on the flood prevention sheet.
According to the present invention, since the protrusion corresponding to the recess of the shutter is formed on the water-proof sheet, the water-proof sheet can be reliably attached to the shutter, and the rain water can be prevented from flooding. it can.

According to the present invention, a masking tape having a predetermined width is attached to one end side of a predetermined full width of the water-proof sheet to the water-proof sheet, and a substantially half-width portion of the masking tape is adhered to the water-proof sheet. It is preferred to apply the layer.
According to the present invention, a half-width portion of a commercially available masking tape having a predetermined width is preliminarily adhered to the water-proof sheet, and the remaining half-width portion is used as an adhesive layer for attaching the water-proof sheet to the outer wall of a house or the like. It can be used. Since the masking tape is an adhesive tape that is scheduled to be peeled off after use, the masking tape is excellent in releasability, and the water immersion prevention sheet can be removed very easily without fouling the outer wall of a house or the like.

  The flooding prevention method for a house or the like of the present invention attaches one end side of a predetermined full width of an indefinite length flexible flood prevention sheet having a predetermined full width exceeding a flooded water level assumed according to local conditions to a shutter. By the simple work of making it possible, the work of attaching the water-proof sheet can be completed within a short time. Since the infiltration prevention sheet can be wound up in a roll shape, it can be stored in a general household without requiring a large storage burden.

  The flooding prevention method for a house or the like according to the present invention enables the outer wall of the shutter or the like to be brought into close contact with the outer wall of the shutter or the like by the water pressure of water that is about to enter the garage or the house. In addition, by using the unevenness of the shutter to ensure the attachment of the upper end of the inundation prevention sheet, or by winding it around the outer walls and pillars of the left and right of the shutter and the entire periphery of the building, the inundation prevention effect is extremely certain.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a flood prevention method for a house or the like of the present invention and a flood prevention sheet used for the flood prevention method will be described below with reference to the drawings.

  The infiltration prevention sheet 10 used for the infiltration prevention method is an adhesive layer 12 made of a pressure sensitive adhesive along one edge of a flexible resin sheet member 11 cut to have a predetermined width and an unspecified length. (FIG. 1). At this time, the predetermined width of the resin sheet member 11 coincides with the predetermined full width L of the normal water immersion prevention sheet 10. The flexible water immersion prevention sheet 10 is wound around the paper tube R in a roll shape in consideration of storage properties and handling properties.

  The requirements for the resin sheet member 11 are that it is water-impermeable, has sufficient flexibility to follow the surface shape of the object, and can be freely deformed. It is preferable not to emit harmful substances, and therefore not to use materials containing chlorine in the molecular chain. Moreover, it is preferably low cost. Moreover, it is preferably low cost. As such a resin material, it is possible to recommend a synthetic resin such as polyethylene resin or vinyl in a general-purpose resin material or a material coated with these. Moreover, since it can confirm the state of a house even when it covers with the transparent infiltration prevention sheet 10, it is preferable that it is transparent.

  The predetermined full width L of the inundation prevention sheet 10 is set to a dimension obtained by adding a sufficient margin dimension to the inundation water level in consideration of the inundation water level assumed according to the local situation such as the past flood damage history in the area, for example. The When a specific flooded water level cannot be assumed, it is considered that 90 cm to 120 cm is sufficient as a general predetermined full width L. Moreover, the length of the infiltration prevention sheet | seat 10 used in the aspect surrounding outer peripheral parts, such as a house, needs the unspecified length exceeding peripheral lengths, such as a house. Even if the perimeter of a house or the like is specified, it can be used in the form of two or three rounds around the outer wall of the house or the like, and the length of the infiltration prevention sheet 10 need not be particularly limited. .

  The pressure-sensitive adhesive layer 12 formed on the water immersion prevention sheet 10 can be formed using a so-called double-sided pressure-sensitive adhesive tape obtained by providing a release paper 13 on one surface of a pressure-sensitive pressure-sensitive adhesive. The double-sided pressure-sensitive adhesive tape 12 is attached to one end edge in the width direction of the resin sheet member 11 over the entire length of an unspecified length along the longitudinal direction. At this time, it is more convenient to leave the release paper 13 without removing it. In addition, although it is necessary to form the adhesion layer 12 over the full length of the unspecified length of the resin sheet member 11, it does not necessarily need to be continued over the full length of the unspecified length. That is, the adhesive layer 12 can be formed so as to form a dotted line.

  The adhesive layer 12 can also be formed using a masking tape 15 having a predetermined width L2 made of a pressure sensitive adhesive (FIG. 2). The masking tape 15 is adhesively applied to one end edge portion of the resin sheet member 11 in such a manner that the half width L1 protrudes from the resin sheet member 11, and the protruding half width L1 portion is the adhesive layer 12 of the water immersion prevention sheet 10. Can function as. In this case, the predetermined full width L of the water immersion preventing sheet 10 matches the dimension obtained by adding the half width L1 of the masking tape 15 to the width of the resin sheet member 11. However, the half width L <b> 1 of the masking tape 15 is a width dimension that can be ignored from the viewpoint of the use of the water immersion prevention sheet 10.

  The flood prevention method for the house of the present invention constructed using the flood prevention sheet 10 as described above causes the flood prevention sheet 10 constructed so as to easily surround the foundation portion of the house 20 to be a cause of flood damage. By bringing the water pressure P of a certain water W into close contact with the outer wall of the house 20, it is possible to exhibit the same infiltration prevention function as that of a highly watertight construction (FIG. 3).

  The house 20 illustrated in FIG. 3 is a house that occupies the mainstream in Japan, which belongs to a building type called a wooden two-story asphalt roofing residence. The “outer wall” in the house 20 is a general term for members that divide the internal environment and the external environment of the house 20, and includes a concrete foundation 21, mortar sprayed or wall surface 23 with an external wall panel, an entrance door 24, a fixed door. This is a concept including a type or opening / closing type glass door 26 and other partition members.

  The concrete foundation 21 of the house 20 is provided with a number of ventilation openings H in addition to the ventilation openings H, H in a front view (FIG. 4), and an approach staircase 22 is installed in front of the entrance door 24. A hot water supply unit 27 is attached to the side surface side of the house 20 along the wall surface 23, and a so-called sweep-out type glass door 26 in which the window frame opening reaches the floor surface level is built on the wall surface 23 on the opposite side surface. (FIGS. 4 and 5). In addition, a door 28 is built on the wall on the back side.

  It is preferable that the construction of the flood prevention sheet 10 on the house 20 starts from a corner portion of the house 20 (FIG. 5). Prior to construction, it is preferable to close the ventilation hole H provided in the concrete foundation 21 with a blind plate B made of, for example, styrene foam. Since the blind plate B made of such a material is easily deformed, it can be easily attached by forcibly fitting the one formed in a slightly larger size than the vent hole H into the vent hole H.

  The inundation prevention sheet 10 is used with the direction of the predetermined full width L as the vertical direction. At this time, a predetermined width L3 of the predetermined full width L is bent horizontally (bent into an L shape) so as to follow the foundation ground G, and the remaining portion of the predetermined full width L is raised along the wall surface 23 of the house 20. Used in the embodiment. The predetermined width L3 along the foundation ground G may be determined according to the condition of the foundation ground G. For example, when the foundation ground G is paved, it may be narrow, and in the case of a gravel ground leveling ground. It needs to be set wider. A weight is preferably placed on the L-shaped part.

  The upper end portion of the infiltration prevention sheet 10 raised along the wall surface 23 is stuck and fixed to the wall surface 23 using the adhesive layer 12. Next, the flood prevention sheet 10 is fed out from the paper tube R while keeping the height position of the upper end of the flood prevention sheet 10 constant, and is arranged around the outer wall of the house 20. Here, although it makes at least one round, it may be a predetermined location that prevents water from entering. Finally, the infiltration prevention sheet 10 is cut by sufficiently overlapping the start end 10A and the end 10B of the infiltration prevention sheet 10.

  The basic construction procedure of the inundation prevention sheet 10 is that when an accessory such as the hot water supply unit 27 exists in the house 20, the hot water supply unit 27 is regarded as a part of the house 20 and is surrounded by the inundation prevention sheet 10 without requiring any work. It is sufficient to construct as shown in Fig. 4. When the foundation ground G has a rising step such as an approach staircase at the entrance, the inundation prevention sheet 10 may be cut off or the construction may be performed as it is. In addition, when the foundation ground G has a falling step, it is possible to partially add the flood prevention sheet 10 for construction.

  The construction of the infiltration prevention sheet 10 is preferably as close as possible to the wall surface 23 around the outer wall of the house 20, but the inundation prevention sheet 10 in the state where the predetermined width L3 of the infiltration prevention sheet 10 along the foundation ground G is secured is secured. As long as the upper end portion of the prevention sheet 10 is higher than the assumed inundation water level D and the inundation prevention sheet 10 is applied at least once around the outer wall of the house 20, a strict contact work is not necessary. Such complete work is also difficult. This is because the infiltration prevention method of the present invention is completed passively when the infiltration sheet 10 in a simple attached state receives the water pressure P of the water W and closely contacts the house 20 (FIG. 1).

The above construction procedure of the infiltration prevention sheet 10 is general-purpose, and can be applied as it is even when the house is the garage 30 (FIG. 6). That is, the feature is that the construction content does not vary greatly even if the construction object is different. The garage is provided with a door for the shutter Sa, and at least makes one turn while maintaining the height position of the upper end portion of the water-inhibiting prevention sheet 10 so as to sufficiently exceed the start end 10A and the end 10B of the water-inhibiting prevention sheet 10. Wrap it. Here, since there is a high possibility that the shutter Sa and one of the left and right walls Sk are constructed by the above construction method, or the gap portion Ss between the shutter Sa and the left and right walls Sb is most likely to be submerged, this gap The portion Ss may have a double structure. Further, in the gap portion Ss, a flexible material spacer Sp is disposed and then covered with the flood prevention sheet 10, or after being covered with the flood prevention sheet 10, the spacer Sp is disposed to form the gap Ss. It may be buried and fixed. Furthermore, the flood prevention sheet 10 may be mounted from the opposite side of the shutter Sa (inside the house) as described above.
Next, FIG. 7 shows a construction in which the infiltration prevention sheet 11 is applied so as to cover the shutter Sa and the left and right walls Sk. In FIG. 7, only the shutter Sa and its left and right sides are constructed, and the adhesive means or the adhesive means 12 is not provided on the upper edge of the infiltration sheet 10, and the shutter Sa is applied from the portion covering the left and right walls Sk. It is arranged along the block Sb. If there is a protruding part such as a block Sb below the left and right walls Sk, the front and rear ends 10A and 10B of the water-inhibiting sheet 10 are extended over these, or further, a weight is placed on the water-inhibiting sheet 10 Even if the adhesive means or the adhesive means 12 is not provided at the upper edge, the water immersion prevention sheet 10 can be attached following the shutter Sa.
When the shutter Sa of a house such as a garage is pulled down to be closed and the inundation prevention sheet 10 is supplied in a state where the shutter Sa is moved from the lower side of the lowered shutter Sa to the position on the ground, there is a block below the left and right walls Sk. The flood prevention sheet 10 is attached in accordance with the shutter Sa using flooded water such as rain water so as to sufficiently extend to a protruding portion such as Sb. By simply disposing in this way, the infiltration prevention sheet 10 can be attached to the shutter Sa without difficulty by inundation such as rainwater. Here, you may attach using the static electricity of the water immersion prevention sheet | seat 10 and the shutter Sa. In addition, it is preferable to arrange | position the lower side pressing member Z distribute | arranged via the infiltration prevention sheet 10 to the lower side edge part (L-shaped part) which closed the said shutter Sa (FIG. 7). Further, by providing the adhesive layer 12 also on the lower side 10k of the infiltration prevention sheet 10 corresponding to the lower side Sg of the shutter Sa, it is possible to ensure the sticking of the shutter Sa to the lower side Sg.
Here, when using attachment means 12 such as adhesive tape, double-sided tape, and hook-and-loop fastener, as shown in FIG. 8 and FIG. Affixed to Sa, or affixed to block Sb first, and then affixed to the upper part of the flooding prevention sheet 10, or affixed so as to be wrapped around the pillar Sf and then affixed to the upper part of the immersion protection sheet 10 Can be worn. Further, when the upper end edge (adhesive layer 12) of the water-inhibiting sheet 10 is attached so as to extend over the uneven part Sc of the shutter Sa, it is possible to prevent water from entering through the gap between the water-inhibiting sheet 10 and the shutter Sa and Adherence is ensured using the part Sc. It is preferable to apply a colored portion 10 c to the upper edge (adhesive layer 12) of the water immersion prevention sheet 10. When the colored portion 10c is located at the same position as the sticking means or the bonding means 12, the workability is improved. However, the colored portion 10c may be wider or shorter than the sticking means or the bonding means 12. it can.
Thus, after covering the door of the shutter Sa with the infiltration prevention sheet 10, the inundation prevention sheet is wound around the outer periphery of the house 20 including the shutter Sa, thereby preventing the entire house from being inundated. The present invention includes a general weight shutter, a fire shutter for outer walls, a grill shutter (the whole is a grill (lattice), and the inside can be seen even when closed), a panel shutter (including a horizontal panel shutter). .) Etc.

  Next, the case where the said flood prevention sheet 10 is given with the waterproof door (door) and the entrance protection enclosure 40 is demonstrated. When it is necessary to go in and out of the house 20 on which the inundation prevention sheet 10 is constructed, the glass door 26 that can be opened and closed can be used in and out. However, even if there is a glass door 26 that can be opened and closed, it is not always in a situation where it can be used for entering and exiting people. As a countermeasure in such a case, the inundation prevention method of the present invention prevents people from entering and exiting the entrance door 24 of the house 20 when the entrance door 24 no longer opens at a height higher than the assumed inundation water level D. It is possible to adopt a method in which the entrance door 24 having the emergency opening 2E that can be installed is installed as a preliminary construction (FIG. 13).

  As far as the inundation prevention method of the present invention is concerned, the opening and closing method of the emergency opening 2E in the entrance door 24 is not questioned. That is, the emergency opening 2E may be a detaching method, a sliding opening / closing method, an opening / closing method by a turning operation, or another opening / closing method. By preparing the entrance door 24 having the emergency opening 2E in advance, it is possible to easily enter and exit the house 20 in which the flood prevention sheet 10 is constructed without opening and closing the entrance door 24 itself from the entrance.

  As another method for ensuring the entrance / exit of a person to / from the house 20 where the inundation prevention sheet 10 is constructed, a method using the entrance protection enclosure 40 can also be employed (FIG. 11).

  The entrance protection enclosure 40 includes a pair of side walls 41 and 41 installed at the left and right positions of the entrance opening of the house 20, portal post-shaped guide posts 42 and 42 attached to the inner side surface of the tip of the side walls 41 and 41, and a guide. It can be assembled from an arbitrary number of dam plates 43 fitted into the guide grooves formed in the posts 42, 42 so as to have an appearance like a gate, for example. The material of the side wall 41, the guide post 42, and the barrier plate 43 is not particularly limited, but it is a requirement that the side wall 41, the guide post 42, and the dam plate 43 have a strength that can withstand the water pressure of water that is about to enter the house 20. The barrier plate insertion method is a blocking method applied to a sluice for adjusting the water level of a small river, and the height of the upper end can be adjusted depending on the number of barrier plates 42 used.

  The entrance protection enclosure 40 as described above can be used for the purpose of protecting the entrance from the wind and rain exclusively without using the dam plate 42 during normal times. The dam plate 42 is used by inserting a necessary number of left and right guide posts 42 and 42 within a height range in which a person can pass in the event of a heavy rain flood warning or the like. The infiltration prevention sheet 10 regards the entrance protection enclosure 40 as a part of the house 20, and is constructed so as to surround the outside. In this method, since the inundation preventing sheet 10 is not applied to the entrance door 24, the opening / closing operation of the entrance door 24 is not hindered even if the outdoor inundation water level rises to a level that reaches the entrance door 24. Therefore, free access to the house 20 to which the flooding prevention method of the present invention has been applied is ensured while preventing water from entering the house 20.

  Here, after the construction of the inundation prevention method of the present invention on the house 20, the lower end edge part in use of the inundation prevention sheet 10, that is, the part along the foundation ground G, is rolled up by the turbulent flow, or floats by the buoyancy of water. In the case where there is a concern that the flood prevention effect is hindered, in order to avoid such a situation in advance, a member having a large specific gravity (such as a metal chain 16 or a weight 17. At least a member having a specific gravity greater than that of water can be added (FIG. 12). Further, in order to achieve the same purpose, a water absorbing member such as linen 18 or towel cloth can be added to the lower edge of the infiltration prevention sheet 10 (FIG. 13).

  When the metal chain 16 or the like is attached to the lower end side of the inundation prevention sheet 10, in order to avoid partial tearing of the lower end side due to local stress concentration, the eyelet 11E is hit on the attachment portion and attached via the eyelet 11E. It is preferable. In addition, in order to add a water absorbing member such as linen 18 or towel cloth, a sewing means is recommended rather than an adhesive means that may hinder the flexibility of the lower end side member due to curing. The water absorbing member added to the lower end edge of the resin sheet can function as a substantial weight by absorbing water, and the lower end edge of the lower end side that is easy to tear is effective without hindering its flexibility. It effectively functions as a replenishing member that can be reinforced, and can also be sold in a cylindrical form.
