Description

  The present invention provides an attachment for a flood prevention sheet and a flood prevention sheet, which can be completed in a short time and have a high flood prevention effect for typhoon forecasts, heavy rain flood warnings, tsunami warnings, river break warnings, etc. It relates to the construction method.

  Advances in weather forecast technology and segmentation of forecast unit areas have greatly 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 building itself is a problem, such as the collapse or loss of the building, etc., there is no room for personal countermeasures and should be evacuated to the designated evacuation site as soon as possible. is there. However, the frequency of such serious disasters is low. The most frequent flood damage and the most serious damage is underfloor inundation or on-floor inundation. The characteristics of such damage in the event of a flood are rare in cases that are life threatening, and household goods are soaked in muddy water and become unusable, hindering 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.
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 building or the like by 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. Further, in Patent Document 4, a seat installed in an opening that communicates an indoor side and an outdoor side of a structure and is opened and closed by an opening / closing body, and the seat at an outdoor side position from the opening / closing body. A holding portion for holding the structure, and the holding portion is configured such that the seat has a predetermined portion on the lower end side in the vertical direction of the opening / closing body and a portion of the structure adjacent to the predetermined portion. The sheet is held so that the lower end in the vertical direction of the opening is closed by covering the sheet, and the lower end in the vertical direction of the sheet extends toward the outdoor side along the floor surface. An opening waterproofing device is disclosed.
In addition, the applicant of the present application also uses the infiltration prevention sheet disposed in the inundation prevention area of the building, and uses the infiltration prevention sheet for preventing the ingress of water into the building and the patent for the infiltration prevention sheet used in this construction method. The application is filed and the contents are disclosed (Patent Documents 5 to 7).

JP-A-9-228495 JP 2003-314173 A JP 2011-99226 A WO 2013/069574 A1 JP 2013-151856 A JP 2013-151854 A JP 2013-151853 A

The inundation prevention measures as in the above-mentioned conventional proposals are considered to be able to exert a sufficient infiltration prevention function with respect to the inventively devised part related to the claim.
However, regarding the window frame opening and the entrance opening, even when the built sliding doors and doors are closed, there is a problem of inundation from the gaps. 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.
Inundation is a problem in the event of flood damage because it affects the overall structure of the building including vents, window frame openings, entrance openings, etc. provided in concrete foundations. Not a problem. For example, even when a water shutter or a water weir is provided, measures to prevent water inflow around other inundation prevention areas such as buildings are a problem unless the whole of the building or the like is enclosed by a water shutter or the like. Moreover, even if the water leakage prevention performance between the panels connected to each other is sufficient, such performance is not obtained for the connection portion between the panel and the separate member.

In addition, as a problem to be solved in order to achieve the above object, it is necessary to satisfy a condition that a member used in the flooding prevention method of the present invention 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 buildings 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.
After the danger of inundation on the building has passed, it is necessary to be able to easily restore the building to its original state. Buildings are designed so that they can provide a predetermined living ring in the completed state. Therefore, leaving the inundation-prevented construction state as it is maintains the original performance of the building, including its useful life. This is because there is a risk that it may cause trouble in the operation, and it is necessary to avoid excessive costs for returning to the original state.

By the way, according to the experiment by the applicant of the present application, when the outer peripheral end such as the lower side of the infiltration prevention sheet is loosened or wrinkled, there is a high probability that water enters the building from the loose gap. On the lower side of the infiltration prevention sheet, a block or the like as a base is disposed, and water enters the building through this block (enters the block so as to ooze). In addition, concrete walls are more effective in preventing flooding than blocks, but even in the case of concrete, flooding is not completely prevented, and depending on the concrete construction condition and construction thickness, flood water may flow through the concrete. Intrude into the building. In the example of FIG. 9, even if the sheet is fixed with the weight 6, it is not possible to completely prevent water from entering the gap.
In addition, the place where water is highly likely to enter the building is from the gap between the sash window and the door sash, and if the infiltration prevention sheet is loosened or wrinkled near the sash window or the door sash, water enters the building. Also, if the infiltration prevention sheet is loosened at the corner (corner) of the building, water enters the building through the loose gap. In other words, it is necessary to keep the inundation prevention sheet in close contact with the building at any position, but it is important how the outer peripheral edge of the infiltration prevention sheet is in close contact, and the central portion is hydraulically attached. Maintained.
In addition, the predetermined full width of the inundation prevention sheet 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 in accordance with the local situation such as the past flood damage history in the area, for example. However, if a specific flood level cannot be assumed, it is necessary to add a flood prevention sheet. However, if a flood prevention sheet is added, there is a high risk of flooding through the gap, and if there is a haze at the connecting point, there is a high risk of flooding and rain will enter.

  Therefore, an object of the present invention is to fix the flood prevention sheet to the outer periphery of the building quickly and surely without causing loosening or wrinkles of the flood prevention sheet, and in particular, the building from the lower side of the flood prevention sheet. An object of the present invention is to provide a fitting device for an infiltration prevention sheet and a method for constructing the infiltration prevention sheet, which prevent intrusion of water into the building and water intrusion into a building from a gap between a window sash and a door sash.

The present invention uses an inundation prevention sheet placed in the inundation prevention area of the building such as the outer wall of the building, shutters, doors, doors, and entrances when there is inundation such as flooding, and allows water to enter the building. In the construction method of the flood prevention sheet to prevent, one side fitting member attached to an outer wall member such as an outer wall, a block, or a pillar arranged on the outer circumference of a building, etc., and the other side to be fitted via the flood prevention sheet A fitting member is provided, and the water-proof sheet is fitted and attached by one-side fitting member and the other-side fitting member.
According to the present invention, an infiltration prevention sheet is fitted to the outer peripheral wall of a building or the like, and the other side fitting member is fitted to the one side fitting member arranged on the outer periphery of the building or the like, so that the outer periphery of the building can be submerged easily and quickly. The prevention sheet can be securely fixed.
As this invention, it is preferable that the other side fitting member is slidable with respect to the said one side fitting member.
According to the present invention, the other side fitting member can be easily attached and detached by sliding the other side fitting member with respect to the one side fitting member.
Further, according to the present invention, the one side fitting member is attached at a predetermined interval, and at least the other side fitting member is arranged using the other side fitting member having a length equal to or longer than the predetermined interval length. It is preferable to press the part which is not made through the water-proof sheet only with the other side fitting member.
According to the present invention, the one-side fitting member can be attached securely at a predetermined location using a short one, and the other-side fitting member longer than this can be reliably attached.

According to the present invention, the one-side fitting member is arranged in advance on an outer peripheral member such as an outer wall, a block, or a pillar of a building, and when necessary to take measures for inundation by weather forecast or the like, The other side fitting member is fitted and attached to the one side fitting member.
According to the present invention, since the one-side fitting member is arranged in advance on an outer peripheral member such as an outer wall of a building, a block, or a pillar, the one-side fitting member is rushed in the case of guerrilla heavy rain or the like. It is not necessary to attach to the building, it is sufficient to attach only the other side fitting member.

The present invention is characterized in that the one-side fitting member is previously attached to a sash window or a door sash.
According to the present invention, since the one-side fitting member is attached in advance to the sash window or the door sash, it is not necessary to hurry and attach the one-side fitting member to the building in the case of guerrilla heavy rain or the like. be able to. Further, unlike the outer wall (concrete or tin) of the building, the sash window and the door sash have less unevenness, and the infiltration prevention sheet can be attached in a close contact state. And although there is a high probability that water will enter from the gap between the sash window and the door sash, it is possible to prevent the water-preventing sheet at the sash window and the door sash from being loosened or wrinkled. That is, according to the present invention, the one-side fitting member and the other-side fitting member can concentrate the places where there is a risk of being flooded, thereby enhancing the flooding prevention effect.

According to the present invention, in order to fix the lower end side of the flood prevention sheet, underlay construction such as concrete or mortar is applied to the ground near the outer wall of the building, and the one side fitting member or the fixing member is attached. It is characterized by.
According to the present invention, it is possible to attach the water-proof sheet in an L-shaped cross section along the outer peripheral wall and the ground. Therefore, there is no situation where the lower end side of the infiltration prevention sheet is drowned, slackened or wrinkled, and water can be completely prevented from entering.

  According to the present invention, the one-side fitting member and the other-side fitting member can concentrate the places where there is a risk of being flooded, thereby enhancing the flooding prevention effect. Even in places where there are steps such as window sashes and door sashes, the infiltration prevention sheet can be easily adhered. In addition, when a concrete or mortar underlay is applied to the ground near the outer wall of the building, and the one-side fitting member or the fixing member is attached, the water leakage prevention sheet is formed in an L-shaped cross section along the outer peripheral wall and the ground. Can be attached in close contact with each other, and the intrusion of water can be completely prevented without dripping the lower end side of the infiltration prevention sheet.

(Construction method for flood prevention sheet)
As shown in FIGS. 1 (a), 1 (b) and 3, the one-side fitting member 1a of the water-proofing sheet mounting device 1 according to the present embodiment is It is good to arrange in advance in window sash Sa or door sash Sd. In this embodiment, they are arranged in the horizontal direction, but they may be arranged regardless of the angle. The fixing member 5 is arranged in advance on the window sash Sa or the door sash Sd. Therefore, when flooding occurs, it is sufficient to fit only the other-side fitting member 1b to the one-side fitting member 1a.
The infiltration prevention sheet 10 is used with the direction of the predetermined full width as the vertical direction. At this time, a predetermined width of the predetermined full width is bent in the horizontal direction so as to follow the foundation ground G, and the remaining portion of the predetermined full width is raised along the wall surface 20 of the building, and is bent in an L shape on the ground to be widened. Set to. The start end and the end of the flood prevention sheet 10 are sufficiently overlapped, and the other side fitting member is fitted to the one side fitting member 1a arranged vertically.

It is also preferable to provide a fixing member 5 for attaching these to the concrete foundation 21 arranged on the outer periphery of a building or the like in advance. Some of the outer walls 20 of the building have grooves m formed at predetermined intervals. Therefore, the fixing member 5 is attached to the groove m. As an attachment method, attachment with screws or attachment with an adhesive or the like is performed, and the one-side fitting member 1 a is attached to the fixing member 5. FIG. 8A shows an example of the fixing member 5 for attaching the fixture (one-side fitting member) 1a in the horizontal direction to the groove m on the outer wall.

Further, at least the upper end side 10a and the lower end side 10b of the flooded waterproof sheet 10 are arranged such that the other-side fitting member 1b is arranged on the entire periphery of the building. In this case, the one-side fitting member 1a does not need to be disposed around the entire periphery of the building, and is sufficient at a predetermined interval. The other-side fitting member 1b is slidable with respect to the one-side fitting member 1a, and the other-side fitting member 1b on the one-wall side and the other-wall-side side, for example, at the outer peripheral corner portion (corner portion) of the building. The other-side fitting member 1b is brought into contact with the other end by sliding it so as to contact each other. With such a close-contact structure, even when it is necessary to add the inundation prevention sheet 10, it is possible to prevent inundation without causing gaps or wrinkles in the added portion, and wrinkles at the connecting portions. Rain does not get in from where it goes.
Moreover, the one side fitting member 1a should be arrange | positioned at predetermined intervals in the perimeter of the building 20, and the other side fitting member 1b may be arrange | positioned without a space | interval corresponding to what is as long as possible. preferable. That is, the one side fitting member 1a is attached with a short length at a predetermined interval, and at least the other side fitting member 1b is used by using the other side fitting member 1b having a length equal to or longer than the predetermined interval length. It is also possible to attach the water immersion prevention sheet 10 only at the other side fitting member 1b at a place where no is disposed. In addition, if it attaches in this way, water will permeate between the one side fitting member 1a and the other side fitting member 1b, and the fitting force of the one side fitting member 1a and the other side fitting member 1b will be increased. Strengthen.

It may be fixed so as to be embedded in the gap of the rubber material Gu (FIG. 3B). The rubber material Gu can be removed from the groove Cm. Furthermore, the infiltration prevention sheet 10 may be arranged in a state of being wound around the cylindrical member Cd (for example, under the window sash) and arranged so as to be pulled out (FIG. 3C). The other side fitting member 1b may be stored and stored in the cylindrical member Cd.

  In this way, the infiltration prevention sheet 10 constructed so as to surround the foundation portion (lower side) of the building 20 is brought into close contact with the infiltration prevention area of the building 20 by the water pressure of the building 20, thereby achieving high watertightness construction. The function of preventing flooding equivalent to that in the case of carrying out can be exhibited. Here, in this specification, “building” includes a residential building, a collective housing, a garage, a warehouse, a warehouse, a factory, a store, and other buildings having a value that is protected from inundation damage. . In addition to buildings (houses) used for residences and the like, water intrusion is completely prevented in houses having a tin or outer wall structure on the base of the block. It is effective to construct the entrance / exit of a convenience store that has a concrete foundation on the outer periphery and does not have a concrete foundation only at the entrance / exit by the construction method of the present embodiment.

  The fixing member 5 can be attached to a wall surface or a glass portion using an adhesive layer. And it arrange | positions to the inundation prevention area | region of the building 20, maintaining the height position of the upper end part of the infiltration prevention sheet | seat 10 constant. The “flooding prevention area” is a general term for members that divide the internal environment and the external environment of the building 20, such as a concrete foundation 21, mortar sprayed or wall surface 23 with a flooding prevention area panel, a front door 24, a fixed type or A thing including the opening-and-closing type glass door 26, a fixture, or other partition members is also applicable. As described above, there may be a level difference between the wall side of the building and the window sash Sa or the door sash Sd. By adjusting the height position (projection amount) of the fixing member 5 with the screw of the fixing member. The above step can be eliminated (FIG. 6).

  In addition, when an accessory such as a hot water supply unit exists outside the building 20, it is constructed so as to be surrounded by the prevention sheet 10 by the one side fitting member 1a and the other side fitting member 1a so as to surround the outer periphery of the hot water supply unit. In addition, when the ground G has a rising step such as an approach staircase at the entrance, it is constructed so as not to cause looseness corresponding to the step. Moreover, in the ventilation hole etc. which were provided in the concrete foundation 21, the said one side fitting member can be bridged and attached, or the attachment tool 1 can also be distribute | arranged so that the outer periphery may be enclosed.

(Experiment)
Actually, a prefab hut was installed, and an experiment by the construction method of the infiltration prevention sheet of the present embodiment was performed (FIGS. 1A and 1B, FIG. 3A). It was found that when the foundation ground G is a block, water enters inside the building (enters into the building). Therefore, concrete C is applied to the lower end side of the outer peripheral wall 20 of the building and the ground nearby, and the fixing member 5 is disposed on the concrete C, and the one-side fitting member 1a is attached to the fixing member 5 to prevent inundation. The other-side fitting member 1a was fitted through the sheet 10. And underlay construction, such as concrete C and mortar, is given to the ground G near the outer wall of the building 20, and the one side fitting member 1a or the fixing member 5 is attached. Therefore, it is possible to reliably prevent rainwater from entering from the lower side 10 b of the infiltration prevention sheet 10.
