Description

  TECHNICAL FIELD The present invention relates to a seal member for sealing between a penetrating sleeve attached to a wall having a gas permeable layer and a moisture-permeable waterproof sheet facing the gas permeable layer, and a sealing method using the seal member.

2. Description of the Related Art For the purpose of durability of a house, an aeration method for discharging moisture such as moisture in a wall has become common. In this ventilation method, a ventilation layer is provided in a wall, and ventilation is performed to the ventilation layer to discharge moisture such as moisture in the wall to the outside.
Generally, the ventilation layer is provided on the outer wall side in the wall. That is, a gap is formed between the inner surface of the outer wall and the outer surface of the heat insulating material and other structural layers provided in the wall, and this is used as a ventilation layer. A moisture-permeable waterproof sheet is laminated on the outer surface of the structural layer in the wall. This moisture-permeable waterproof sheet prevents the rainwater that may leak from the outside into the ventilation layer from entering the structure layer, and discharges the water vapor that has entered the structure layer from the room to the ventilation layer side, Prevents condensation inside the wall.

When an air conditioner or the like is retrofitted to a wall having such a ventilation layer, a through hole is provided to connect the outdoor unit and the indoor unit, and a through sleeve is passed through the through hole. In order to close the gap between the through hole and the through sleeve, a putty or a sealing material is generally used. Here, the gap between the holes on the outer and inner walls and the through sleeve can be easily closed by applying a putty or the like from the outside.
Please refer to Patent Literatures 1 and 2 as literatures introducing technologies related to this case.

Japanese Patent No. 5582873 JP-A-2017-145581

However, it has been difficult to fill the gap between the hole formed in the element in the wall and the through sleeve. This is because the holes provided in the outer wall and the inner wall for passing the through sleeve are small in the first place, and it is troublesome to work inside through the holes.
In particular, regarding a hole made in the moisture-permeable waterproof sheet facing the ventilation layer, if there is a gap between the hole and the penetrating sleeve, the waterproof function may not be able to be achieved in the first place.
Accordingly, an object of the present invention is to provide a seal member that can easily close a gap between a through-sleeve attached to a wall having a ventilation layer and a hole in a moisture-permeable waterproof sheet.
Another object of the present invention is to provide a sealing method for sealing between a through sleeve and a moisture-permeable waterproof sheet using such a sealing member.

The seal member defined in the first aspect of the present invention has been made to solve at least one of the above problems. That is,
A sealing member for sealing between a penetration sleeve that is retrofitted to a wall having a ventilation layer and a moisture-permeable waterproof sheet facing the ventilation layer,
A sleeve outer insertion portion to be extrapolated to the through sleeve, and a flange portion formed from a flexible material and provided upright from the outer periphery of the sleeve outer insertion portion to the outside thereof,
A slit formed in a radial direction of the flange portion, wherein the slit communicates with the sleeve outer insertion portion, and the flange portion can be reduced in diameter by overlapping both edges of the slit. With a slit,
A sealing member comprising:

According to the sealing member defined in the first aspect defined as above, when a force is applied so that both edges of the slit formed in the flange are overlapped, the diameter of the flange is reduced. The reduced diameter flange can be easily inserted into the hole in the outer wall. Since the material of the inserted flange portion is flexible, when the force for reducing the diameter is removed, the flange portion returns to the original shape in the wall (in the ventilation layer). In this state, the flange portion is brought into contact with the periphery of the hole of the moisture-permeable waterproof sheet.
Here, if the surface of the flange portion that comes into contact with the moisture-permeable waterproof sheet has adhesiveness, the flange portion is bonded to the periphery of the hole of the moisture-permeable waterproof sheet, so that waterproofness between the two can be ensured.
Since the flange part is erected from the outer periphery of the sleeve extrapolation part to the outside, if the sealability between the flange part and the sleeve extrapolation part is to be ensured in the first place, it will penetrate through the sleeve extraneous part. If the sealing property with the sleeve is ensured, the moisture on the ventilation layer side will not pass through the holes formed in the moisture-permeable waterproof sheet to the inside thereof.
In the present invention, after the flange portion is adhered to the periphery of the gas permeable layer, the slit between the sleeve insertion portion and the through sleeve is easily sealed by, for example, closing the slit of the sleeve insertion portion with a waterproof tape or the like. Can be secured.

The second aspect of the present invention is defined as follows. That is, in the seal member according to the first aspect, an adhesive layer is formed on the flange portion on a surface facing the moisture-permeable waterproof sheet, and the adhesive layer is covered with a removable protective film.
According to the sealing member defined in the second aspect defined as above, since the adhesive layer is formed on the surface of the flange portion facing the moisture-permeable waterproof sheet, the surface is formed with the hole of the moisture-permeable waterproof sheet. If it is brought into contact with the peripheral edge, the sealing property of that portion can be ensured. Further, since the adhesive layer is covered with the protective film, it does not adversely affect the workability when the flange portion is passed through the hole in the outer wall.

The third aspect of the present invention is defined as follows. That is, in the sealing member defined in the second aspect, the protection member includes a fixing portion attached to the surface of the protective film, and a pickup portion connected to the fixing portion and disposed along the sleeve outer insertion portion. A film remover is further provided,
The fixing portion moves by pulling out the pickup portion along the sleeve insertion portion, and the protection film is peeled off from the adhesive layer with the movement of the fixing portion.
According to the sealing member of the third aspect defined in this manner, since the protective film removing tool is provided, the diameter of the flange member is released in the ventilation layer in the wall, and then the pickup portion is moved along the sleeve insertion portion. , The protective film can be easily removed from the adhesive layer. Therefore, workability is improved.

The fourth aspect of the present invention is defined as follows. That is, in the seal member according to any one of the first to third aspects, the flange portion is formed at one end of the sleeve outer insertion portion, and the slit is formed to the other end in the axial direction of the sleeve outer insertion portion. You.
According to the seal member of the fourth aspect defined in this manner, since the slit is formed in the axial direction of the sleeve insertion portion, the other end of the sleeve insertion portion is connected to the slit formed therein. When the diameter is reduced so that both edges overlap, the diameter of the flange portion is also reduced, and the workability is improved.

The fifth aspect of the present invention is defined as follows. That is, in the seal member defined in the fourth aspect, the slit is formed in parallel with the axis of the sleeve insertion portion, and is formed in the flange portion in a radial direction from the axis of the sleeve insertion portion.
According to the sealing member of the fifth aspect defined in this way, since one slit is formed in the axial direction, the production of the slit is facilitated, and the manufacturing cost of the sealing member is reduced.

The seal member according to the sixth aspect of the present invention is defined as follows. That is, in the seal member defined in the second aspect, a second adhesive layer is formed on the other surface of the flange portion, and the second adhesive layer is covered with a removable second protective film.
According to the seal member of the sixth aspect defined as above, the adhesive layers are formed on both surfaces of the flange portion. Such a flange portion is inserted between a structural material layer such as a heat insulating material and a moisture-permeable waterproof sheet in a wall, and adheres to both. The connection surface between the flange portion and the moisture-permeable waterproof sheet is on the structural material layer side when viewed from the moisture-permeable waterproof sheet, and there is no connection surface on the ventilation layer side. Therefore, it is possible to more reliably prevent water dripping from entering the surface on the ventilation layer side. By bonding the flange portion and the structural body layer, the gap therebetween is sealed, so that the airtightness as a whole is improved. Further, by double bonding the flange portion to the wall structure, the sealing member is more stable.

The seventh aspect of the present invention is defined as follows. That is, a sealing method for sealing between a penetration sleeve that is retrofitted to a wall having a ventilation layer and a moisture-permeable waterproof sheet facing the ventilation layer,
A step of inserting the flange portion of the seal member according to any one of the first to sixth aspects into an insertion hole of a penetration sleeve penetrated through an outer wall, wherein both edges of the slit are moved in an overlapping direction.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, a construction state of the seal member 1 according to the embodiment will be described with reference to FIG.
FIG. 1 shows a wall structure provided with a ventilation method, in which a ventilation layer 9 is formed along the outer wall 4. Reference numeral 6 denotes a structural layer. In this example, the structural layer 6 is composed of a heat insulating material layer 6A and a structural plywood 6B. A moisture-permeable waterproof sheet 7 is adhered to the surface of the structural plywood 6B.

A hole 2 is formed in each element of the wall structure so that the penetrating sleeve 3 penetrates.
The seal member 1 according to the embodiment includes a sleeve outer insertion portion 11 and a flange portion 13. The sleeve outer insertion portion 11 is externally inserted into the penetrating sleeve 3, and the flange portion 13 extends to the periphery of the hole 2 of the moisture-permeable waterproof sheet 7. Watertightly bonded (sealed).

Reference numeral 5 denotes a sealant which fills a gap between the hole 2 of the outer wall 4, the sleeve insertion portion 11 of the seal member 1 and the through sleeve 3, and performs sealing.
In FIG. 1, elements that are intentionally sealed (ie, treated to prevent water leakage) are drawn in contact.
From FIG. 1, it can be seen that even if the hole 2 is drilled later on the moisture-permeable waterproof sheet 7, the hole 2 and the ventilation layer 9 are sealed by the sealing member 1. That is, since the flange portion 13 of the seal member 1 is adhered to the moisture-permeable waterproof sheet 7, water that has entered the ventilation layer 9 does not pass through the holes 2 of the moisture-permeable waterproof sheet 7.

Next, the seal member 1 will be described in detail.
As shown in FIGS. 2 to 4, the seal member 1 according to the embodiment includes a main body 10, a protective film 20, and a protective film removing tool 30.
The main body 10 includes a cylindrical sleeve insertion portion 11 and a flange portion 13 that rises outward from the edge of one end of the sleeve insertion portion 11 in the radial direction. A single slit 14 is formed in the sleeve outer insertion portion 11 and the flange portion 13 to divide them in the axial direction.

In the above description, a bent portion 12 is formed at one end of a cylindrical sleeve outer insertion portion 11 constituting the main body portion 10. The bent portion 12 can be extended from the sleeve insertion portion 11 by molding. In this example, a large number of cuts were made at one end of the tubular member, and the bent portion 12 was formed by bending outward. The flange portion 13 is an annular member, and an adhesive layer 18 is provided on the entire back surface thereof, and is fixed to the bent portion 12 through the adhesive layer 18 in a liquid-tight manner. The remainder of the adhesive layer 18 is covered with a protective film 20.
In this example, the sleeve insertion portion 11 and the flange portion 13 are separate bodies, but these can be integrally molded. The flange portion 13 may be integral or separate as long as it rises from the outer periphery of the sleeve outer insertion portion 11 to the outside in the radial direction without any gap, that is, without any permeation of moisture.
In the example of FIG. 2, the flange portion 13 rises from one end of the sleeve outer insertion portion 11, but the flange portion 13 may rise from any position on the outer periphery.

The flange portion 13 is an annular member formed outside the outer periphery of the sleeve outer insertion portion 11, and comes into contact with the periphery of the hole 2 formed in the moisture-permeable waterproof sheet 7.
The shape of the flange portion 13 is not particularly limited as long as it can surround the hole 2 by 360 degrees. However, considering the workability at the time of diameter reduction, the shape of the flange portion 13 is to be annular, that is, the width of the inner peripheral portion and the outer peripheral portion is constant over the entire circumference. Preferably, there is.
When a flange portion is provided at a portion other than the end of the sleeve external insertion portion 11, it is preferable to provide a circumferential cut in the external insertion portion 11 in order to allow the flange to escape.

It is preferable that the flange portion 13 is formed of a flexible material so as to return to the original shape when the force for reducing the diameter is removed after the diameter is once reduced. Needless to say, since it is used for a wall, it is necessary to have waterproofness and weather resistance.
Examples of such a material include metal materials such as copper, aluminum, and stainless steel, resin materials such as polyethylene terephthalate, polyethylene, polypropylene, and polycarbonate, and elastomer materials such as EPDM, silicone rubber, urethane rubber, and butyl rubber.
It is preferable that the thickness of the flange portion 13 be as thin as possible so that it can be easily deformed by human force after having a rigidity that does not break when the flange portion 13 is reduced in diameter and folded. In this example, the thickness was 0.1 to 0.4 mm.
The flange portion can be formed radially outward from the outer peripheral surface of the sleeve outer insertion portion 11, that is, perpendicular to the axis. The flange portion may be provided to be inclined with respect to the sleeve insertion portion 11. When the penetration sleeve is inclined with respect to the wall due to rain, it is preferable to provide a flange on an imaginary plane inclined with respect to the axis of the penetration sleeve, and to make the flange parallel to the wall.

It is preferable that the molding material of the sleeve insertion portion 11 has not only waterproofness and weather resistance but also flexibility like the flange portion 13.
The thickness of the sleeve outer insertion portion 11 can be the same as that of the flange portion 13.
The diameter of the sleeve insertion portion 11 is slightly larger than the diameter of the penetrating sleeve 3 to facilitate insertion of the penetrating sleeve 3. Further, the diameter is slightly smaller than the diameter of the hole 2 of the outer wall 4. This is to secure a space for the sealant to reach the inside of the wall.
The length of the sleeve insertion portion 11 is such that the distance from the flange portion 13 to the tip portion is longer than the distance from the moisture-permeable waterproof sheet 7 on the wall to the outer surface of the outer wall 4. This is because the sleeve outer insertion portion 11 can be operated in a state where the flange portion 13 is applied to the moisture-permeable waterproof sheet 7. After the seal member 1 is mounted, as shown in FIG. 1, the distal end side of the sleeve outer insertion portion 11 is cut along the outer surface of the wall 4 and sealed with the sealing material 5.

  A first slit 15 is formed in the flange portion 13 across the radial direction, that is, from the inner periphery to the outer periphery. A second slit 16 is formed in the sleeve insertion portion 11 so as to communicate with the first slit 15. The second slit 16 is formed in the sleeve insertion portion 11 in the axial direction, that is, continuously from one end to the other end where the flange portion 13 is connected. The second slit 16 does not have to be cut to the other end in the sleeve insertion portion 11. This is because it is only necessary to reduce the diameter of one end of the sleeve outer insertion portion 11 as long as the diameter of the flange portion 13 is not hindered.

The first slit 15 and the second slit 16 are preferably formed as a single slit 14 along the axial direction, as shown in FIG. This is because fabrication is easy.
The first slit 15 of the flange portion 13 may be provided at an angle. That is, the first slit 15 is inclined with respect to the normal of the inner peripheral edge (or outer peripheral edge) of the flange portion 13. Further, the second slit 16 of the sleeve outer insertion portion 11 can also be provided to be inclined. Even in the case where the first and second slits are provided inclined as described above, it is preferable that the first and second slits are formed as one.
Furthermore, two or more slits may be provided, that is, the main body (sleeve insertion portion 11 and flange portion 13) may be divided. In this case, it is preferable to have a function of joining the divided main body parts to the protective film 20 for alignment.

An adhesive layer 18 is provided on the back surface of the flange portion 13. The adhesive layer 18 is preferably formed on the entire surface of the flange portion 13, but is assumed to be continuous at least in the circumferential direction from the viewpoint of ensuring sealing properties (excluding the slit 15). Its width is 30 to 50 mm.
The adhesive layer 18 is not particularly limited as long as it is made of a material which adheres to the moisture-permeable waterproof sheet 7 and exerts a waterproof function thereon, but rubber materials such as butyl rubber, polyisobutylene rubber, rubber asphalt, acrylic, polyurethane, Resin-based materials such as silicon-based and polyester-based materials can be used.
If the material for forming the flange portion 13 can be fused to the moisture-permeable sheet 7 by heat or high frequency, or if the moisture-permeable waterproof sheet 7 can be coated with an adhesive or filled with a sealing material in advance, This adhesive layer can be omitted.

  A protective film 20 is laminated on the surface of the adhesive layer 18 to prevent the adhesive layer 18 from adhering to an object other than the target (the moisture-permeable waterproof sheet 7). A known release material is applied to the protective film 20 so that the protective film 20 can be easily peeled off from the adhesive layer 18 by human power.

A protective film removing device 30 is attached to the protective film 20. The protective film removing tool 30 includes a fixing unit 31 and a pickup unit 33.
The fixing part 31 is fixed to the surface of the protective film 20. The fixing position of the fixing portion 31 is preferably the peripheral portion of the slit 15. This is because the peeling of the protective film 20 can be easily performed from its end. The pickup unit 33 is arranged along the slit 16 of the sleep extrapolation unit 11, and its base end is connected to the fixing unit 31. As a result, when the pickup unit 33 is pulled, the fixing unit 31 moves to the sleeve insertion unit 11 side, whereby the protective film 20 is sequentially peeled off.
In this example, the protective film removing section 30 was constituted by a series of flexible tapes. One end of the tape is affixed to the protective film 20 as the fixing portion 31 along the slit 16. This tape is folded at the outer edge of the protective film 20 and stretched along the inner peripheral surface of the sleeve outer insertion portion 11 to become the pickup portion 30.
The pickup section 33 can be replaced with a rod having high rigidity or other rod material.

FIG. 5 shows an implementation example.
When both edges of the slit 14 are overlapped with each other on the seal member 1 and the sleep outer insertion portion 11 is gripped and reduced in diameter, the flange portion 13 also reduces in diameter and becomes a cone as shown in FIG. 5A. In this state, it is inserted into the hole 2 of the outer wall 4 (FIG. 5B). Here, since the flange portion 13 is reduced in diameter and has flexibility in itself, the flange portion 13 easily passes through the hole 2.
After that, when the diameter is released, the flange portion 13 is returned flat in the wall structure, that is, in the ventilation layer 9 (FIG. 5C). Next, the pickup portion 11 of the protective film removing tool 30 is pulled along the sleeve insertion portion 11 to peel off the protective film 20 from the adhesive layer 18 (FIG. 5D). Thereafter, the flange portion 13 is pressed around the hole 2 of the moisture-permeable waterproof sheet 7 using a jig, and both are bonded in a liquid-tight manner (FIGS. 5E and 5F).

Next, the second slit 16 formed in the sleeve insertion portion 11 is sealed with a waterproof tape (FIG. 5G). The sleeve insertion portion 11 protruding from the outer wall 4 is removed (FIGS. 5H and 5I), and then the second penetrating sleeve 3b is inserted (FIG. 5J).
Finally, the gap between the peripheral wall of the hole 2 of the outer wall 4, the sleeve insertion portion 11, and the through sleeve 3b is filled with a sealing material and sealed (FIG. 5K, L).
FIG. 6 shows a manner of attaching the seal member 1 to the moisture-permeable waterproof sheet 7 when the outer wall 4 is removed.

FIG. 7 shows a seal member 101 of another embodiment. In the seal member 101, a sleeve insertion portion 111 and a flange portion 113 are integrally formed. An adhesive layer 118 is formed on the entire surface of the flange portion 113, and this is protected by a protective film 120.
A series of tapes is used as the protective film removing device 130 in the same manner as in the example of FIG. In this example, a slit 134 is formed in the circumferential direction near the distal end of the sleeve external insertion portion 111, and the pickup portion 133 is inserted into the slit 132. As a result, the pip-up portion 133 is always in a state along the sleeve outer insertion portion 111, and does not hinder the work.

FIG. 8 illustrates a state of application of another form of the sealing member 201 with reference to FIG. In FIG. 8, the same elements as those in FIG. 1 are denoted by the same reference numerals, and the description thereof will be partially omitted.
In FIG. 8, an adhesive layer is formed on both surfaces of a flange portion 213 of the seal member 201, and the flange portion 213 is adhered to the periphery of the hole of the structure layer 6 and the moisture-permeable waterproof sheet 7. In the example shown in FIG. 8, the flange 213 is bonded to the back surface of the moisture-permeable waterproof sheet 7 (as viewed from the ventilation layer 9). For this reason, the joint between the flange portion 213 and the moisture-permeable waterproof sheet 7 is not exposed on the ventilation layer 9. Therefore, the water dripping along the surface on the side of the ventilation layer 9 in the moisture-permeable waterproof sheet 7 can be more reliably blocked.

Next, the configuration of the seal member 201 is shown in FIGS. 9 to 11, the components described in FIGS. 2 to 4 are denoted by the same reference numerals, and the description thereof will be partially omitted.
In the seal member 201, the adhesive layers 18, 218 are formed on both surfaces of the flange portion 213. An adhesive layer 218 is formed on the surface of the flange portion 213 on the sleeve insertion portion 11 side, and the adhesive layer 218 is protected by a protective film 220.
A protective film removing tool 230 is connected to the protective film 220. The protective film removing tool 230 is made of a series of tapes, and one end thereof is fixed along the slit 16 from the inner peripheral edge of the protective film 220 as a fixing portion 231. This tape is folded at the outer peripheral edge of the protective film 220 and is disposed along the outer peripheral surface of the sleeve outer insertion portion 11 to form the pickup portion 233.

The method of applying the sealing member 201 having such a configuration is the same as that shown in FIG. 5, but the flange portion 213 from which the protective films 20 and 220 are removed is provided between the structural layer 6 and the moisture-permeable waterproof sheet 7 in the wall structure. Insert
FIG. 12 shows a state after completion, and FIG. 12 shows a state in which the outer wall 4 has been removed. The flange portion 13 is applied to the moisture-permeable waterproof sheet 7 from the back side, and is adhered thereto.

  FIG. 13 shows a seal member 401 of another embodiment. 13, the same members as those in FIGS. 7 and 11 are denoted by the same reference numerals, and the description thereof will be partially omitted. In this example, an adhesive layer 318 is formed on the entire surface of the upper surface of the flange portion 113 (on the side of the sleeve insertion portion) and is protected by the protective sheet 320. On the other hand, an adhesive layer 418 is formed on the entire back surface of the flange portion 113 and is protected by the protective sheet 420. For this purpose, a series of tapes is used as the protective film removing tool 330 in the same manner as in the example of FIG. In this example, the pickup section 331 is passed through the slit 134.

  In the above example, the case where the ventilation layer is formed on the outer wall side has been described as an example. However, when this is formed on the inner wall side, the process is performed using holes formed on the inner wall.

  The present invention is not limited to the description of the embodiment and the example of the above invention. Various modifications are included in the present invention without departing from the scope of the claims and within the scope of those skilled in the art.
