However, the exterior wall repair method disclosed in Patent Literature 1 has a problem in that when applied to an exterior wall panel including a core material and an exterior panel, deterioration in appearance is likely to occur.

The present invention solves such problems. It is an object of the present invention to provide an exterior wall panel repair method capable of reducing the possibility of deterioration of the exterior appearance of an exterior wall panel comprising a core material and exterior panels arranged outside the building.

Exterior wall panel repair methods of the present invention are described. The reason why the symbols in the drawings are used in this column is to facilitate understanding of the content of the invention, and is not intended to limit the content to the illustrated range.

In order to solve the above-described problems, according to one aspect of the present invention, the exterior wall panel repair method includes a removal step S250 and a covering material application step S254. In the removing step S250, the raised portion 70 on the exterior plate 52 of the outer wall panel 30 is removed. The exterior wall panel 30 is arranged on the exterior wall of the building 20 . The exterior wall panel 30 comprises the exterior plate 52 . The outer wall panel 30 comprises a core material 50 in addition to the exterior plate 52 thereof. The exterior plate 52 is arranged outside the building 20 from the core material 50 . A ridge 70 is removed from the outside of the building 20 . In the covering material attaching step S254, the covering material 90 is attached to the outer wall panel 30 so as to cover the exterior panel 52 after the raised portion 70 is removed. The exterior wall panel repair method further includes a hole-filling plate sticking step S252. In the hole-filling plate sticking step S252, a hole-filling plate material 92 having the same thickness as that of the exterior plate 52 is fitted into the hole 80 formed by removing the raised portion 70 of the exterior plate 52, and the hole-filling plate material 92 is It is attached to the core material 50 . In this case, in the covering material attaching step S254, after the hole-filling plate material 92 is attached, the covering material 90 is added to the exterior plate 52 so that the exposed portion of the exterior plate 52 is covered together with the hole-filling plate material 92. It is attached to the filling plate material 92 .

A hole-filling plate material 92 having the same thickness as that of the exterior plate 52 is fitted into a hole 80 formed by removing the raised portion 70 of the exterior plate 52 , and the hole-filling plate material 92 is attached to the core member 50 . After the hole-filling plate material 92 is adhered, the covering material 90 is adhered to the hole-filling plate material 92 in addition to the exterior plate 52 so that the exposed portion of the exterior plate 52 is covered together with the hole-filling plate material 92 . As a result, the hole-filling plate material 92 is not exposed. Furthermore, it is possible to avoid the situation where the covering material 90 is not stuck anywhere in the place facing the hole 80 formed by removing the protuberance 70 . By avoiding this situation, it is also possible to avoid a situation in which the bonding strength between the covering material 90 and the exterior plate 52 is lowered due to this situation. Since the hole-filling plate material 92 is not exposed and the adhesion strength between the covering material 90 and the exterior plate 52 is avoided, the possibility of deterioration of the appearance of the outer wall panel 30 is reduced.

If a new sticking film 150 is provided, the defect can be eliminated. On the other hand, if the exterior plate pasting film part 112 is made of one sticking film, and a defect occurs in any part of it, the one sticking film is removed and a new sticking film is provided. There is a need. Thus, when the exterior plate attaching film portion 112 has a plurality of attaching films 150, 150, the exterior plate attaching film portion 112 can be easily provided.

Alternatively, it may be desirable for the lower edge of an exterior wall panel 30 having the raised portion 70 described above to cover the upper edge of another exterior wall panel 34 . In this case, it is desirable that the covering surface forming portion 110 has a plate-like portion 190 and a lower insertion piece portion 192 made of a metal plate. A predetermined surface of the plate-like portion 190 serves as the exposed surface 130 . A back surface of a predetermined surface of the plate-like portion 190 serves as the opposing surface 132 . The lower insertion piece portion 192 is arranged at a position that becomes the lower end of the plate-like portion 190 when the covering material 90 is attached to the exterior plate 52 of the outer wall panel 30 having the raised portion 70 . The lower insert piece 192 is inserted between the exterior wall panel 30 having the raised portion 70 and another exterior wall panel 34 . The lower insertion piece portion 192 protrudes obliquely upward when the covering material 90 is attached to the exterior plate 52 .

The lower insertion piece portion 192 protrudes obliquely upward when the covering material 90 is attached to the exterior plate 52 . On the other hand, the lower edge of an exterior wall panel 30 having a ridge 70 covers the upper edge of another exterior wall panel 34 . As a result, the covering material 90 can be temporarily fixed by the lower insertion piece portion 192 . At this time, the covering surface forming portion 110 of the covering material 90 protrudes from the outer wall of the building 20 . The lower insertion piece portion 192 is made of a metal plate. Since the lower insertion piece portion 192 is made of a metal plate, it becomes easy to stand or lay down the covering surface forming portion 110 . As a result, when the covering surface forming portion 110 is attached to the covering plate 52 and the hole-filling plate material 92 by the covering plate attaching film portion 112, the covering surface forming portion 110 is attached to the covering plate 52 and the covering plate 52 while the covering material 90 is freely movable. The pasting work is easier than when pasted to the hole-filling plate material 92 .

[Description of operation]
Specific operations in the exterior wall panel repair method according to the present embodiment will be described below.

First, the worker goes in front of the ridge 70 of the exterior wall panel 30 described above. In this case, the operator is brought in front of the ridge 70 by a well-known portable gondola. A worker in front of the ridge 70 draws a line around the ridge 70 . In the case of this embodiment, the line is drawn by well-known marking. After the line is drawn around the protuberance 70, the operator cuts the protuberance 70 and its periphery from the exterior plate 52 along the line. In the case of this embodiment, the operator cuts off the raised portion 70 and its surroundings with an electric sander. When the ridge 70 and its perimeter are cut, a hole 80 is formed where the cut was made. In this embodiment, the hole 80 is assumed to be rectangular. The worker removes the burrs formed on the edge of the hole 80 with an electric sander (S250). FIG. 5(A) is a diagram showing the completion status of the removal step S250 according to this embodiment. As is clear from FIG. 5(A), the core material 50 is exposed from the hole 80 formed at the location where the protuberance 70 was formed at the completion of the removal step S250.

After the burrs are removed, the operator applies an acrylic adhesive to the hole-filling plate material 92 . In this case, in this embodiment, the hole-filling plate material 92 is a flat steel plate. The material of this steel plate is the same as the material of the exterior plate 52 . The thickness of this steel plate is the same as the thickness of the exterior plate 52 . The shape of the hole-filling plate 92 is the same as the holes 80 described above. Since a line is drawn around the raised portion 70 in the removing step S250 and the exterior plate 52 is cut along the line, the shape of the hole-filling plate material 92 can be made the same as the hole 80 described above. As a result, the hole-filling plate material 92 fits snugly into the hole 80 formed by the operator cutting the raised portion 70 and its periphery. In the case of this embodiment, the adhesive is uniformly applied to the entire surface of the hole-filling plate material 92 that is in close contact with the core material 50 . The worker presses the hole-filling plate material 92 coated with the adhesive against the core material 50 exposed through the hole 80 described above. As a result, the hole-filling plate material 92 is fitted into the hole 80 described above, and the hole-filling plate material 92 is adhered to the core material 50 (S252).

After the hole-filling plate material 92 is attached to the core material 50, the operator conveys the covering material 90 in front of the exterior plate 52 in which the hole 80 is formed (S270). In this case, the covering material 90 is transported by a known portable gondola.

FIG. 6 is an external view of the covering material 90 according to this embodiment. The covering material 90 according to this embodiment has a covering surface forming portion 110 and an exterior plate attaching film portion 112 . In addition, in FIG. 6, a part of the exterior plate attaching film portion 112 is notched.

In the case of this embodiment, the covering surface forming portion 110 is formed of a known steel plate. The covering surface forming portion 110 forms an exposed surface 130 (see FIG. 7) and a facing surface 132 . The exposed surface 130 is a surface exposed to the outside of the building 20 when the covering material 90 covers the exterior plate 52 and the hole-filling plate material 92 . The facing surface 132 is a surface facing the exterior plate 52 and the hole-filling plate material 92 when the covering material 90 covers the exterior plate 52 and the hole-filling plate material 92 . In this embodiment, the covering surface forming portion 110 has a plate-like portion 190 , a lower insertion piece portion 192 and an upper insertion piece portion 194 .

The plate-like portion 190 is a plate-like portion of the covering surface forming portion 110 .

The upper protruding portion 212 protrudes upward from the tip of the inner protruding portion 210 when the covering material 90 is attached to the exterior plate 52 of the outer wall panel 30 having the raised portion 70 .

The exterior plate-attached film portion 112 is arranged on the facing surface 132 . In the case of this embodiment, the exterior plate attaching film portion 112 has two attaching films 150 , 150 . Those sticking films 150, 150 are arranged side by side. As is clear from FIG. 6 , these sticking films 150 , 150 are arranged so as to extend along the horizontal direction when the covering material 90 is stuck to the exterior plate 52 of the exterior wall panel 30 having the raised portion 70 . In the case of this embodiment, the sticking films 150, 150 are formed by uniformly applying a known adhesive to the surface of a butyl sheet. In the case of the present embodiment, release paper (not shown) is attached to the surfaces of the adhesive films 150 , 150 . The reason why the release paper is stuck is to protect the surfaces of the sticking films 150 , 150 .

When the covering material 90 described above is conveyed, the worker attaches the covering material 90 to the exterior plate 52 so as to cover the exposed portions of the exterior plate 52 in which the holes 80 are formed (S272). . For this purpose, the lower insert piece 192 of the cladding 90 is first inserted between the outer wall panel 30 having the raised portion 70 and another outer wall panel 34 arranged therebelow.

FIG. 7 is a diagram showing a state in which the lower insertion piece portion 192 is inserted between the outer wall panels 30 and 34. As shown in FIG.

A horn 60 of an exterior wall panel 30 having a ridge 70 covers the upper edge of another exterior wall panel 34 positioned therebelow. Thereby, as shown in FIG. 7, the worker inserts the lower insertion piece while the plate-like portion 190 is tilted between the outer wall panel 30 having the raised portion 70 and the outer wall panel 34 disposed therebelow. A portion 192 can be inserted. When the lower insertion piece 192 is inserted between the outer wall panels 30 and 34 , the operator brings the plate-like portion 190 closer to the outer wall panel 30 .

When the plate-like portion 190 is brought close to the outer wall panel 30 , the operator inserts any member between the lower insertion piece portion 192 of the covering material 90 and the outer wall panel 34 . In this embodiment, that member is referred to as backup member 230 . FIG. 8 is a diagram showing a state in which the backup member 230 is inserted between the lower insertion piece portion 192 and the outer wall panel 34. As shown in FIG. This backup member 230 is inserted to prevent the covering material 90 from falling.

Next, the operator lays down the plate-like portion 190 outward. As a result, the plate-like portion 190 tilts with the lower insertion piece portion 192 as a fulcrum. When the plate-like part 190 is tilted, the operator peels off release paper (not shown) from the two sticking films 150 , 150 . As a result, the exterior plate attachment film portion 112 of the covering material 90 is brought into a state in which it can be adhered. After the release paper is peeled off, the operator brings the plate-like portion 190 closer to the outer wall panel 30 again. As a result, the covering material 90 is attached to the exterior plate 52 again (S274).

When the plate-like portion 190 is brought closer to the outer wall panel 30 again, the operator applies pressure to the entire surface of the covering material 90 so that the covering material 90 is pressed against the exterior panel 52 (S276). In this embodiment, the pressure is applied sequentially from the center of the covering material 90 toward both ends. Rubber rollers are used for this purpose. As a result, the covering surface forming portion 110 is adhered to the exterior plate 52 and the hole-filling plate material 92 by the exterior plate attaching film portion 112 . Moreover, since pressure is applied to the entire surface of the covering material 90, both of the two sticking films 150, 150 adhere the covering surface forming portion 110 to at least one of the exterior plate 52 and the hole-filling plate material 92. . In addition, the exposed portion of the exterior plate 52 is covered with the covering material 90 .

When pressure is applied to the entire surface of the covering material 90, the worker fixes the covering material 90 to the exterior plate 52 by passing screws through the exposed portions of the upper insertion piece 194 (S278). After the covering material 90 is fixed to the exterior plate 52 , the operator peels off the protective film attached to the exposed surface 130 of the plate-like portion 190 . After peeling off the protective film, the operator seals the outer circumference of the covering material 90 (S280). When the sealing of the outer circumference of the covering material 90 is completed, the exterior wall panel repair according to the present embodiment is completed.

[Description of effects of the present embodiment]
