[Efficacy of invention]

According to the wall repair method and wall structure of the present invention, since the top plate of the flat wall material on the lower side is covered by the plate-shaped cover material, the time of cutting off the fastening member can be saved, and the damaged flat plate can be repaired more efficiently Wall material.

Hereinafter, a mode for implementing the present invention will be described with reference to the drawings. [Implementation form] FIG. 1 is a front view of the wall structure before repair using the method of repairing the wall of the embodiment of the present invention, and FIG. 2 is a side view of the three flat wall materials stacked in FIG. 1. The wall structure shown in FIG. 1 and FIG. 2 is formed by arranging a plurality of flat wall materials 1 having a flat shape on the surface of the wall base.

Specifically, in the left-right direction 2 (horizontal direction) of the wall, the flat wall materials 1 are arranged so that their side ends are butted. Also, as shown in FIG. 2 in particular, in the vertical direction 3 (vertical direction) of the wall perpendicular to the left and right direction 2, each flat wall material 1 overlaps a part of the flat wall material 1 on the upper side and is arranged on the flat wall on the lower side.材1 on the surface.

In addition, in the left-right direction 2, the flat wall material 1 on the upper side is staggered with respect to the flat wall material 1 on the lower side so as to reach half of the extension width of the flat wall material 1 along the left-right direction 2. That is, in the left-right direction 2, the butting part of the side end of the flat wall material 1 on the upper side is offset from the butting part of the side end of the flat wall material 1 on the lower side.

Each flat wall material 1 is fastened to the wall base by driving in fastening members 4 such as nails or screws. Furthermore, the fastening member 4 is covered by the flat wall material 1 on the upper side, and only a part of the fastening member 4 is shown by a broken line in FIG. 1.

For the purpose of explanation below, the plurality of flat wall materials 1 arranged side by side in the left-right direction 2 may be referred to as a row of flat wall materials 1. According to this expression, the first row of flat wall materials 1 (1A), the second row of flat wall materials 1 (1B), and the third row of flat wall materials 1 (1C) are shown in FIG. 2. A second row of flat wall materials 1B is arranged on the upper side of the first row of flat wall materials 1A, and a third row of flat wall materials 1C is arranged on the upper side of the second row of flat wall materials 1B. The fastening member 4 (4B) driven into the flat wall material 1B of the second row penetrates the flat wall material 1A of the first row to reach the wall base. Moreover, the fastening member 4 (4C) driven into the flat wall material 1C of the third row penetrates the flat wall material 1B of the second row and reaches the wall base.

Furthermore, the terms of the first row to the third row described above only refer to the three rows of the flat wall materials 1 staggered in the up-down direction 3, and do not limit the positions of the rows of the entire wall structure. In other words, other flat wall materials 1 may be arranged under the first row of flat wall materials 1A.

Next, FIG. 3 is a front view of the flat wall material 1 of FIG. 1, FIG. 4 is a rear view of the flat wall material 1 of FIG. 3, and FIG. 5 is a cross-sectional view of the flat wall material 1 along the line IV-IV of FIG. 3. As shown in FIGS. 3 to 5, the flat wall material 1 has a front view substantially rectangular outer shape having a long side direction 1L (width direction) and a short side direction 1S (height direction). The flat wall material 1 is arranged on the surface of the wall base such that the long side direction 1L is along the left-right direction 2 of the wall and the short side direction 1S is along the wall up-down direction 3 (refer to FIG. 1). As shown in FIGS. 3 to 5, the flat wall material 1 is a metal wall material having a surface base material 12, an inner base material 13 and a core material 14.

The watch base 12 is a metal member using a metal plate as a material, and is a member that appears on the outer surface of the wall when the flat wall material 1 is placed on the surface of the wall base. As shown in FIG. 5, the watch base 12 is provided with a box-shaped main body 120 having a top plate 120 a and a peripheral wall 120 b.

As shown in FIG. 3, a plurality of fastening holes 121 are provided in the longitudinal direction 1L (left-right direction 2) of the flat wall material 1 in the top plate 120a of the watch base material 12 at intervals. The fastening hole 121 indicates the position where the fastening member 4 (refer to FIG. 1) is driven into the flat wall material 1. In the present embodiment, the description is made with the fastening hole 121 provided in the watch base material 12. However, instead of the fastening hole 121, for example, printed marks or projections and depressions that indicate the driving position of the fastening member 4 may be used. The opening-shaped mark is provided on the top plate 120a.

The peripheral wall 120b of the watch base 12 is provided with a first side surface 122, a second side surface 123, an upper end surface 124, and a lower end surface 125.

The first side surface 122 and the second side surface 123 are respectively arranged on both sides of the flat wall material 1 in the longitudinal direction 1L. The second side surface 123 is matched in such a way that when the flat wall material 1 is arranged on the surface of the wall base, it is located on the upper side of the first side surface 122. The second side surface 123 is arranged at a position protruding to the outside of the longitudinal direction 1L of the flat wall material 1 rather than the first side surface 122.

A side flange 122a is provided on the first side surface 122. The side flange 122a is formed by sandwiching the inner base material 13 by a metal plate extending from the front end of the first side surface 122 to the outside in the longitudinal direction 1L. The inner side of the watch base material 12 is folded back and formed. By providing the side flange 122a integrally with the main body 120, the flat wall material 1 is resistant to the external force (wind pressure resistance performance) when the flat wall material 1 is warped to the front side or the inside along a straight line along the longitudinal direction 1L. )improve. The protruding width of the side flange 122 a from the first side 122 is set to be less than the protruding width of the second side 123 from the first side 122.

There is no flange on the second side surface 123. The reason why there is no flange on the second side surface 123 is that the flange extending from the second side surface 123 is cut and removed after the box-shaped body portion 120 is formed.

The upper end surface 124 is located at one end along the short side direction 1S, and is fitted in such a way that it is located on the upper side when the flat wall material 1 is arranged on the surface of the wall base. A straight portion 124a and a pair of inclined portions 124b are provided on the upper end surface 124. The linear portion 124a linearly extends along the longitudinal direction 1L. The inclined portion 124b is arranged on both sides of the straight portion 124a so as to connect the straight portion 124a and the second side surface 123. In addition, the inclined portion 124b extends obliquely with respect to the straight portion 124a toward the lower side (the other end side along the short side direction 1S) as it approaches the second side surface 123.

As shown in FIGS. 3 and 5 in particular, the straight portion 124a of the upper end surface 124 is provided with an upper flange 124c. The upper flange 124c extends from the front end of the upper end surface 124 to the outside along the short side direction 1S. The metal plate is folded back to the inner side of the watch base material 12 so as to sandwich the inner base material 13 and is formed.

The inclined portion 124b of the upper end surface 124 is not provided with a flange. Similar to the second side surface 123, the reason why the inclined portion 124b of the upper end surface 124 is not provided with a flange is that the flange protruding from the inclined portion 124b is cut and removed after the box-shaped body 120 is formed. However, the same flange as the upper flange 124c may be provided on the inclined portion 124b.

The lower end surface 125 is located at the other end along the short side direction 1S, and is fitted in such a way that it is located on the lower side when the flat wall material 1 is placed on the surface of the wall base. In the flat wall material 1 of this embodiment, the lower end surface 125 is comprised only by the linear part extended along the longitudinal direction 1L. However, the lower end surface 125 may also have other shapes.

A lower flange 125a is provided on the lower end surface 125. The lower flange 125a is a metal plate extending from the front end of the lower end surface 125 to the outside along the short side direction 1S to sandwich the inner substrate 13 The method is folded back to the inner side of the watch base material 12 to be formed.

The upper flange 124c and the lower flange 125a extend along the longitudinal direction 1L, and prevent the flat wall material 1 from warping in a direction crossing the longitudinal direction 1L.

Regarding the metal plate as the material of the table base material 12, you can use: molten zinc (Zn) coated steel sheet, molten aluminum (Al) coated steel sheet, molten Zn coated stainless steel sheet, molten Al coated stainless steel sheet, stainless steel Plate, Al plate, Titanium (Ti) plate, coated molten Zn coated steel sheet, coated molten Al coated steel sheet, coated molten Zn coated stainless steel sheet, coated molten Al coated stainless steel sheet, coated stainless steel Plate, coated Al plate or coated Ti plate. When the watch base material 12 is made into a box shape, it is preferable to draw the steel plate to form the watch base material 12. The reason for drawing the steel plate to form the watch base material 12 is that by drawing the steel plate, work hardening occurs on the peripheral wall 120b, and the wind pressure resistance of the flat wall material 1 can be improved. In addition, the reason why the surface base material 12 is formed by drawing the steel sheet is that the peripheral wall 120b can be formed as a wall surface continuous in the circumferential direction of the surface base material 12.

The inner base material 13 is a member disposed on the inner side of the watch base material 12 so as to block the opening of the main body 120. As the inner substrate 13, lightweight materials such as aluminum foil, aluminum vapor-deposited paper, aluminum hydroxide paper, calcium carbonate paper, resin film, or glass fiber paper can be used. By using these lightweight materials for the inner base material 13, the weight increase of the flat wall material 1 can be avoided.

The core material 14 is made of, for example, foamed resin and the like, and is filled between the main body 120 and the inner base material 13. The material of the core material 14 is not particularly limited, and urethane, phenol, nurate resin, etc. can be used. However, non-combustible certified materials must be used in wall materials. Regarding the certification test of non-combustible materials, a heat release test based on the ISO (International Organization for Standardization) 5660-1 cone calorimeter test method is implemented. In the case where the foamed resin used as the core material 14 is a urethane or the like with a large amount of heat, the thickness of the core material 14 can be reduced, or the foamed resin can contain inorganic foamed particles. Compared with the case where the inner nail material such as a resin sheet is attached to the inner side of the watch base material 12, the core material 14 can be firmly adhered to the watch base material 12 by filling the foamed resin between the main body 120 and the inner base material 13 The inner surface of the base material 12 can also improve the performance required for wall materials such as rain sound, heat insulation, and step resistance.

Next, FIG. 6 is a front view of the plate-shaped cover material 5 used in the wall repair method of the embodiment of the present invention, and FIG. 7 is a cross-sectional view of the plate-shaped cover material 5 along the line VII-line VII of FIG. 6 , FIG. 8 is a cross-sectional view of the plate-shaped cover material 5 along the line VIII-line VIII of FIG. 6.

The plate-shaped cover material 5 shown in FIG. 6 is used for the damaged flat wall material 1 when one of the plurality of flat wall materials 1 arranged as shown in FIG. 1 is damaged. Make repairs. As described below with the use of drawings, the plate-shaped cover material 5 is overlapped and arranged on the flat wall material 1 in such a way as to cover the top plate 120a of the damaged flat wall material 1. In addition, in FIGS. 6 to 8, a two-dot chain line represents the flat wall material 1 on which the plate-shaped cover material 5 is overlapped. The plate-shaped cover material 5 has a shape that when the plate-shaped cover material 5 covers the top plate of the flat wall material 1 (the flat wall material 1 on the lower side), the outer edge of the plate-shaped cover material 5 is accommodated inside and outside the outer edge of the flat wall material 1 .

As with the flat wall material 1, the plate-shaped cover material 5 has a substantially rectangular outer shape in a plan view having a long side direction 5L (width direction) and a short side direction 5S (height direction). The material of the plate-shaped cover material 5 is arbitrary, but it is preferably the same material as the top plate of the flat wall material 1. In the case where the flat wall material 1 is composed of a metal wall material of a metal plate by the watch base material 12 as described above, the plate-shaped cover material 5 is preferably formed of a metal plate in the same manner as the watch base material 12. For example, when the top plate 120a of the flat wall material 1 is subjected to surface treatment such as painting or uneven processing, it is preferable to perform the same surface treatment on the surface of the plate-shaped cover material 5. The same surface treatment mentioned here, in addition to strictly the same surface treatment, also includes: when the table base material 12 of the flat wall material 1 and the plate-shaped cover material 5 are separated by a few meters to see There is no significant difference between the surface of the plate-shaped cover material 5 and the surface of the surface base material 12, and it is the same kind of surface treatment for the impression of the same kind of article.

The plate-shaped cover material 5 is provided with a pair of side end portions 50, a lower side end portion 51 and an upper side end portion 52.

As shown in FIG. 7, the side end 50 of the plate-shaped cover material 5 is arranged along the top plate 120 a of the flat wall material 1. In other words, the side end 50 is not provided with a vertical wall along the peripheral wall 120b of the flat wall material 1. By not providing the vertical wall at the side end 50, when the plate-shaped cover material 5 is inserted between the flat wall materials 1 as described later, the plate-shaped cover material 5 can be moved toward the front side or along the straight line along the longitudinal direction 5L. The inside warps easily. Furthermore, the width of the plate-shaped cover material 5 along the longitudinal direction 5L is equal to or slightly smaller than the width of the top plate 120a of the flat wall material 1 along the longitudinal direction 5L.

As shown in FIG. 8, the lower end 51 is provided with a vertical wall 51 a along the peripheral wall 120 b (lower end surface 125) of the flat wall material 1. By providing the vertical wall 51a at the lower end 51, the plate-like cover material 5 can be prevented from warping along the straight line along the short side direction 5S. Moreover, by butting the vertical wall 51a and the peripheral wall 120b, the positioning of the plate-shaped cover material 5 along the short side direction 5S can be reliably performed. When the plate-shaped cover material 5 covers the top plate 120a of the flat wall material 1 (lower flat wall material), the lower flange 125a protrudes outward from the lower part of the vertical wall 51a. In addition, in this embodiment, although it demonstrates by providing the vertical wall 51a in the lower side edge part 51, this vertical wall 51a may be abbreviate|omitted. In addition, an extension wall like the lower flange 125a that clamps or covers the flat wall material 1 may protrude from the front end of the vertical wall 51a.

The upper end 52 is provided with a straight portion 52a and an inclined portion 52b. The linear portion 52a linearly extends along the longitudinal direction 5L. In addition, the linear portion 52a extends to a substantially central position of the plate-shaped cover material 5 along the longitudinal direction 5L. The inclined portion 52b is arranged on both sides of the straight portion 52a so as to connect the straight portion 52a and the side end portion 50. In addition, the inclined portion 52b extends obliquely with respect to the straight portion 52a so as to go to the lower side as it approaches the side end portion 50.

The width between the straight portion 52a and the lower end 51 along the short-side direction 5S is preferably larger than the lower end and the third end of the first row of flat wall materials 1A along the vertical direction 3 shown in FIG. The separation distance D1 between the lower end portions of the row flat wall materials 1C. With such a configuration, when the plate-shaped cover material 5 is inserted between the first row of flat wall materials 1A and the second row of flat wall materials 1B, the plate-shaped cover material 5 can be extended to the third row of flat wall materials. Below the butting part of the side end of the second row of flat wall materials 1B covered by the material 1C (refer to FIG. 10). Thereby, it is possible to prevent moisture infiltrated from the abutting portion of the side end of the second row of flat wall materials 1B from entering between the flat cover material 5 and the first row of flat wall materials 1A.

The upper end 52 is provided with a water return portion 52c obtained by folding back the plate constituting the plate-shaped cover material 5 from the inner surface side to the surface side. By providing the water return portion 52c at the upper end 52, it is possible to prevent the water that penetrates from the butt portion of the side end of the second row of flat wall materials 1B from crossing the upper end 52 and entering the plate-shaped cover material 5 and the first row of flat wall materials 1A between.

The fastening member 4B driven into the flat wall material 1B of the second row penetrates to the lower end of the flat wall material 1A of the first row. If the width between the straight portion 52a and the lower end 51 along the short-side direction 5S is widened, the fastening member 4B driven into the second row of the flat wall material 1B interferes with the plate-shaped cover material 5 The possibility becomes higher. By providing the inclined portion 52b at the upper end 52 as described above, it is possible to reduce the possibility of interference between the fastening member 4B driven into the second row of flat wall materials 1B and the plate-shaped cover material 5.

Next, the repairing method of the wall of the embodiment of the present invention will be described. In addition, the repairing method of the wall of this embodiment is equivalent to the manufacturing method of the repaired wall structure. FIG. 9 is an explanatory diagram showing a wall repair method according to an embodiment of the present invention, and FIG. 10 is an explanatory diagram showing a wall structure to which the wall repair method of FIG. 9 is applied.

As shown in FIG. 9, imagine a wall structure in which a second row of flat wall materials 1B is arranged on the upper side of the first row of flat wall materials 1A, and a third row of flat wall materials 1C is arranged on the upper side of the second row of flat wall materials 1B. In the first row, the top plate of the flat wall material 1A is damaged. At this time, insert the plate-shaped cover material 5 between the first row of flat wall materials 1A and the second row of flat wall materials 1B (between the flat wall materials on the lower side and the flat wall materials on the upper side), as shown in Figure 10 The top plate 120a of the first row of flat wall materials 1A is covered by the plate-shaped cover material 5. Thereby, the damaged flat wall material 1A of the first row can be left and the top plate 120a of the first row of flat wall material 1A can be repaired. In other words, it is possible to save time and effort for cutting off the fastening members for fastening the first row of flat wall materials 1A, or for extracting the first row of flat wall materials 1A. This configuration is particularly useful when the fastening member 4B driven into the flat wall material 1B of the second row also penetrates the flat wall material 1A of the first row.

Before inserting the plate-shaped cover material 5, the adhesive can be applied to the inner surface of the plate-shaped cover material 5, and after the plate-shaped cover material 5 is inserted, the plate-shaped cover material 5 can be attached to the first row of flat wall materials 1A. In addition, a fastening member such as nails or screws may be inserted into the plate-shaped cover material 5 and then driven into the plate-shaped cover material 5 to fasten the plate-shaped cover material 5 to the wall base. The bonding and fastening of the plate-shaped cover material 5 may be performed either or both.

The insertion of the plate-shaped cover material 5 is performed until the vertical wall 51a (refer to FIG. 8) provided at the lower end 51 of the plate-shaped cover material 5 abuts or approaches the peripheral wall 120b of the first row of flat wall materials 1A. When inserting the plate-shaped cover material 5, the side end 50 of the plate-shaped cover material 5 is not provided with a vertical wall along the peripheral wall 120b of the plate wall material 1, so the plate-shaped cover material 5 can be made along the long side The straight line in the direction 5L is warped.

As shown in FIG. 10, in the state where the plate-shaped cover material 5 is inserted between the first row of flat wall materials 1A and the second row of flat wall materials 1B, the plate-shaped cover material 5 extends to the third row of flat wall materials 1C Below the end of the lower side. Thereby, it is possible to prevent the moisture infiltrated from the abutting part of the side end of the second row of flat wall materials 1B from entering between the flat cover material 5 and the first row of flat wall materials 1A.

According to such a wall repair method and wall structure, since the top plate 120a of the flat wall material 1 on the lower side is covered by the plate-shaped cover material 5, the time and labor of cutting the fastening member 4 can be saved, and the warp can be repaired more efficiently. Damaged slab wall material 1. This configuration is particularly useful when the flat wall material 1 is formed of a metal wall material having a surface base material 12, an inner base material 13 and a core material 14.

In addition, since the plate-shaped cover material 5 has the top plate 120a of the plate-shaped cover material 5 covering the flat wall material 1 on the lower side, the outer edge of the plate-shaped cover material 5 is accommodated in and out of the outer edge of the lower plate wall material 1 Therefore, it is possible to repair specific wall materials without changing the appearance of the wall.

In addition, since the plate-shaped cover material 5 is composed of a metal plate in the same manner as the surface base material 12, it is possible to avoid the plate-shaped cover material 5 from being conspicuous due to the difference from the surrounding flat wall material 1.

In addition, since the plate-shaped cover material 5 inserted between the first row of flat wall materials 1A and the second row of flat wall materials 1B extends below the lower end of the third row of flat wall materials 1C, it can be avoided from the first row. The moisture infiltrated at the abutting parts of the side ends of the two rows of flat wall materials 1B enters between the plate-shaped cover material 5 and the first row of flat wall materials 1A.

In addition, since the upper end of the plate-shaped cover material 5 is provided with a return portion 52c obtained by folding back the plate material constituting the plate-shaped cover material 5 from the inner surface side to the surface side, it is possible to avoid the flat wall material from the second row. The moisture penetrated into the abutting part of the side end of 1B passes over the upper end 52 and enters between the plate-shaped cover material 5 and the first row of flat wall material 1A.

In addition, since the side ends of the plate-shaped cover material 5 are arranged along the top plate of the flat wall material, the plate-shaped cover material 5 can be warped along the straight line along the longitudinal direction 5L, and the plate-shaped cover The material 5 is more efficiently inserted between the first row of flat wall materials 1A and the second row of flat wall materials 1B.

In addition, since the vertical wall 51a along the peripheral wall 120b of the flat wall material 1 is provided at the lower end of the plate-shaped cover material 5, it is possible to warp the plate-shaped cover material 5 along a straight line along the short side direction 5S. The endurance is improved, and the positioning of the plate-shaped cover material 5 along the short side direction 5S is reliably performed.

In addition, since the vertical wall is along the lower end surface, the positioning of the plate-shaped cover material 5 along the short side direction 5S can be reliably performed.

In addition, since the plate-shaped cover material 5 is attached to the top plate 120a of the flat wall material 1 on the lower side, the plate-shaped cover material 5 can be prevented from deviating from the flat wall material 1.

In addition, since the plate-shaped cover material 5 is fastened to the wall base together with the flat wall material 1 on the lower side, the plate-shaped cover material 5 can be prevented from deviating from the flat wall material 1.

Furthermore, in the embodiment, although the flat wall material 1 is formed by a metal wall material having a surface base material 12, an inner base material 13 and a core material 14 is described, the present invention can also be applied by, for example, The wall materials of the ceramics system such as slabs constitute flat wall materials.
