Description

Technical Field

[0001] The present invention relates to a water intrusion prevention sheet for preventing water intrusion from gaps such as doors and windows of buildings during water level rise such as floods and tsunamis caused by heavy rain in recent years.

Background Art

[0002] Conventionally, as damages that occur during water level rise such as floods and tsunamis caused by heavy rain, there are disasters such as flooding under the floor or flooding above the floor. Such disasters called water damage occur when sewage and sludge enter into the walls or under the floor of a house, causing condensation in the walls or under the floor, rotting the wooden parts such as the foundation, and also causing sanitary damages due to the generation of various bacteria and molds contained in the sewage and sludge. Furthermore, electric leakage damages also occur due to sewage and sludge.

[0003] For example, Patent Document 1 describes a fixture for a water intrusion prevention sheet that has a fitting portion attached to the outer periphery of a building at one end and can attach a water intrusion prevention sheet at the other end. By sandwiching the water intrusion prevention sheet, a technique for preventing water from entering the building from the lower side of the water intrusion prevention sheet is described.

[0004] Patent Document 2 describes a water stop plate having a predetermined height for an area where water intrudes into a building such as an outer wall of a building. A first water stop plate that contacts the ground surface is provided at the lowermost stage, and a second water stop plate is provided above this first water stop plate. And a technique for preventing water from entering the building by arranging a flexible member in the gap between the first water stop plate and the second water stop plate and forming it so as to eliminate the gap is described.

Summary of the Invention

Problems to be Solved by the Invention

[0006] According to the methods described in Patent Documents 1 and 2, it is necessary to place heavy objects to prevent flooding so that there are no gaps between the flood-prevention sheet and the ground or floor surface that is in contact with it in the horizontal direction, which requires labor and time to transport these heavy objects. Furthermore, while it is fine to use water-blocking plates and sheets when a disaster occurs, when they are not in use and no disaster has occurred, they take up space for storage, resulting in wasted space.

[0007] The objective of this invention is to provide a flood prevention sheet that can be placed on the exterior of a building to prevent the intrusion of mud and other debris into the house, and that can be quickly installed in the event of a disaster. Furthermore, the objective is to provide a flood prevention sheet that does not require installation work, is inexpensive, and can be easily and quickly installed even by women and the elderly. [Means for solving the problem]

[0008] To achieve the above objective, a flood prevention sheet is installed around the perimeter of a building to protect the building from disasters such as floods, and the sheet prevents water from entering the building. The invention is characterized by comprising a main body portion arranged parallel to the sheet, a laying support portion provided on the lower end side of the main body portion, and an elastic sheet pressing member joined to the laying support portion. [Effects of the Invention]

[0009] According to the present invention, flood prevention sheets can be easily installed during floods caused by heavy rain, tsunamis, and other water-related disasters. Furthermore, the invention provides flood prevention sheets that do not require installation work using heavy machinery, are inexpensive, and can be easily and quickly installed even by women and the elderly. [Brief explanation of the drawing]

[0010] [Figure 1] This is a perspective view showing a flood prevention sheet according to one embodiment of the present invention. [Figure 2] Figure 1 is a perspective view showing the use of the flood prevention sheet shown in the diagram. [Figure 3] Figure 1 is a close-up view of the main part showing the usage state when the flood prevention sheet is in use. [Figure 4] Figure 1 is a perspective view showing the use of the flood prevention sheet shown on the building. [Modes for carrying out the invention]

[0011] One embodiment of the present invention will be described below with reference to the drawings.

[0012] The flood prevention sheet 1 according to this embodiment will be described with reference to Figures 1 to 4. For convenience, parts that perform the same function are denoted by the same reference numerals and their descriptions are omitted.

[0013] As shown in Figure 4, the flood prevention sheet 1 is placed around the building H. This flood prevention sheet 1 is used to prevent flooding into the building H by being installed on the outer perimeter of the building H. As shown in Figure 1, the flood prevention sheet 1 comprises a sheet 2, a main body 3, a sheet fastening member 4, and a laying support part 5.

[0014] Sheet 2 can be placed around building H during floods to prevent damage from inundation. The size of Sheet 2 can be changed as needed depending on the size of building H and the installation environment, but specifically, its height is about 30 cm to 100 cm and its thickness is about 0.5 mm to 2.0 mm. Note that if Sheet 2 is too thick, it may be difficult to handle, and if it is too thin, the waterproofing function may be insufficient.

[0015] Sheet 2 is flexible and can be folded, saving storage space when stored inside building H. It is also lightweight and easy to handle, making it easy for even women or elderly people with limited strength to install.

[0016] The sheet 2 is preferably a synthetic resin sheet formed by appropriately blending polyethylene-based resins such as polyethylene, polyethylene-based copolymers obtained by copolymerizing ethylene with vinyl acetate, etc., olefin-based resins such as polypropylene resin, vinyl chloride-based resins, various elastomer-based resins, etc. Further, it only needs to have a strength such that it does not break even when in contact with foreign matters such as wood and gravel washed in by water.

[0017] The main body part 3 will be described. The shape of the main body part 3 is plate-shaped. Along the longitudinal direction of this plate shape, the sheet 2 is joined. For example, joining by welding, an adhesive, a bonding agent or a joining tool, sewing, or a surface fastener can be mentioned. In the case of sewing, an over-tape is used so that the sewing part is hidden to prevent water leakage into the building H. And when joining the sheet 2 and the main body part 3, by performing the joining using one surface of the main body part 3, the joining area with the sheet 2 can be secured, and stable joining of the sheet 2 and the main body part 3 can be performed.

[0018] Note that the shape of the main body part 3 is not limited to plate-shaped, and various changes can be made without departing from the gist of the present invention. For example, within a range where it does not receive water resistance, it can be a polygonal shape such as a substantially square prism having a straight part on one side, a semi-circular shape, etc. Further, although the main body part 3 extends in the longitudinal direction, ribs for reinforcement may be provided in the middle. Also, when attaching to the sheet 2, a stable joining of the main body part 3 and the sheet 2 can be performed by joining to the sheet 2 using a joining member such as a surface fastener for the diameter part.

[0019] The main body part 3 is arranged parallel to the building H and perpendicular to the ground G. A laying auxiliary part 5 is provided on the lower end side of the main body part 3. The laying auxiliary part 5 is formed by bending one end of the main body part 3 or by joining an arc-shaped member.

[0020] The main body part 3 may be formed of a synthetic resin appropriately blended with an olefin resin such as a polyethylene resin or a polypropylene resin, a vinyl chloride resin, various elastomer resins, etc., but may also be made of a metal such as iron, aluminum, stainless steel, copper, etc. The material is not limited to this as long as it has the strength to press-contact the sheet 2 in a direction perpendicular to the building H.

[0021] The height of the main body part 3 may be the same as that of the sheet 2. By making it the same height as the sheet 2, it is possible to prevent water generated during a flood from entering the building H. Specifically, the main body part 3 can hold the sheet 2 in a direction perpendicular to the building H from the ground G, so that the sheet 2 can be closely adhered to the outer wall of the building H without a gap. As a result, flooding of the building H can be reliably prevented.

[0022] Next, the sheet pressing member 4 will be described. The sheet pressing member 4 has a flat plate shape arranged in parallel with the elastic main body part 3. Also, a laying auxiliary part 5 is interposed between the sheet pressing member 4 and the main body part 3.

[0023] When the flood prevention sheet 1 is stored, the sheet pressing member 4 is arranged in parallel with the main body part 3. And as shown in FIGS. 2 and 3, when the flood prevention sheet 1 is in use, the sheet pressing member 4 is arranged in a vertical direction (outside the building) with the building H on the back side from the main body part 3. Specifically, in addition to the self-weight of the main body part 3, the sheet pressing member 4 forms an arc so as to follow the outer periphery of the laying auxiliary part 5 described later due to the weight of water, sludge, etc. generated during a flood. That is, when viewed from the side, the sheet pressing member 4 is composed of an arc part 4A that draws an arc and a straight part 4B arranged in parallel as described above.

[0024] The straight portion 4B of the sheet-holding member 4 is installed to cover the sheet 2 laid on the ground G. As a result, the weight of the main body 3 and the weight of water and sludge apply a load to the sheet 2 in the direction of the ground G. This load allows the sheet 2 to be installed without any gaps against the ground G, preventing water and sludge from entering the building H. Furthermore, the weight of the main body 3 and the weight of water and sludge applied to the straight portion 4B prevents the sheet 2 from moving on its own, ensuring that it is securely fixed in the desired position. As a result, flooding can be reliably prevented in the area where flooding is to be prevented.

[0025] As mentioned above, the arc portion 4A of the sheet-holding member 4 is formed along the outer circumference of the laying support portion 5. By forming this arc portion 4A, the load applied to the sheet-holding member 4 is transferred to the laying support portion 5, thereby preventing damage or breakage of the sheet-holding member 4.

[0026] The sheet-holding member 4 may be made of metal such as carbon steel, stainless steel, or nickel alloy, but it may also be made of non-metallic material such as natural rubber, synthetic resin, or ceramic, as long as it is made of an elastic material.

[0027] The sheet-holding member 4 is installed to cover the sheet 2, but the length of the sheet-holding member 4 in the longitudinal direction is not limited to this; as mentioned above, it may be shorter than the sheet 2 as long as it can prevent a gap between the sheet 2 and the ground G.

[0028] Furthermore, although the shape of the sheet-holding member 4 has been described as flat, it is not limited to this shape. Any shape that can securely hold the sheet 2 against the ground G, bend along the laying support section 5, and prevent damage or breakage of the sheet-holding member 4 is acceptable.

[0029] The installation support section 5 will now be described. The installation support section 5 is formed by bending the main body section 3 or by joining an arc-shaped member.

[0030] The shape of the laying support section 5 is arc-shaped. The width of the laying support section 5 is approximately the same as the width of the sheet retaining member 4, and it is desirable that the load be applied evenly to the laying support section 5 when the arc portion 4A of the sheet retaining member 4 contacts the laying support section 5 and forms an arc. In other words, when the sheet retaining member 4 is in use, it is placed on the ground G, so when the sheet retaining member 4 deforms at approximately a right angle, the arc portion 4A is formed. And when this arc portion 4A is formed, the laying support section 5 is also arc-shaped, so the laying support section 5 receives the pressure from the outside to the inside of the arc and becomes integrally the same shape, which prevents damage to the sheet retaining member 4 and prevents the board from returning to its original shape.

[0031] The installation support section 5 is made of the same material as the main body section 3, but if it is to be joined as a separate component, it may be made of a synthetic resin formed by appropriately blending polyethylene terephthalate resin, polyvinyl alcohol, polycarbonate, polyamide, fluororesin, phenolic resin, melamine resin, unsaturated polyester resin, etc.

[0032] The installation method for the flood prevention sheet 1 will now be explained. The main body 3 and the sheet 2 are installed in a joined state. In other words, the sheet 2 is installed in the area of ​​the building H where flooding is to be prevented. The sheet 2 is installed from the same height as the main body 3 down to the ground G. A sheet fastening member 4 is installed on top of the sheet 2 installed on the ground G.

[0033] The main body 3 is joined to the sheet 2 at equal intervals. As mentioned above, any known adhesive can be used for joining. If the sheet 2 is not long enough to cover the area in building H where flooding should be prevented, the sheet 2 can be joined together via the main body 3. In this case, the joints should be joined appropriately to prevent water leakage. Alternatively, the sheet 2 and the main body 3 can be joined together in advance and stored, and the sheet 2 can be installed in the area of ​​building H where flooding should be prevented during construction.

[0034] The main body 3 is installed perpendicular to the ground G and parallel to the building H. Due to the weight of the main body 3, the sheet retaining member 4, which is parallel to the main body 3, is pressed against the ground G, forming a straight portion 4B of the sheet retaining member 4 parallel to the ground G. Since this straight portion 4B of the sheet retaining member 4 is positioned on top of the sheet 2 which is installed above the ground G, it can prevent the sheet 2 from moving unintentionally. In addition, the arc portion 4A of the sheet retaining member 4 is formed along the periphery of the laying support portion 5, which is provided to prevent breakage or damage to the sheet retaining member 4 when it is pressed against the ground G under load. Furthermore, the laying support portion 5 can also act as a guide for where the arc portion 4A of the sheet retaining member 4 should bend.

[0035] Furthermore, this construction method allows for easy installation of the water-prevention sheet 1 to the building H and the ground G without requiring conventional methods such as adhesive, bonding, or hook-and-loop fasteners.

[0036] Specifically, by utilizing the water pressure generated during a disaster, the flood-prevention sheet 1 installed in the area of ​​building H where flooding is to be prevented will adhere tightly to the building H without any gaps in the direction perpendicular to the ground G, and tightly adhere to the ground G without any gaps in the direction parallel to the building H, thereby reliably preventing flooding of building H.

[0037] Herein, in this specification, "building H" includes not only ordinary houses for residential use, but also apartment buildings, garages, warehouses, storehouses, factories, shops, and other structures that have value in protecting against flood damage.

[0038] In addition to what has already been described above, the methods of the above embodiments and their respective modifications may be used in appropriate combinations. Although not given as examples here, the present invention can be implemented with various modifications without departing from its spirit. [Explanation of Symbols]
