Embodiment FIG. 1 is a plan view showing a wall structure before repairing to which a wall repairing method according to an embodiment of the present invention is applied, and FIG. 2 shows three flat plate wall members arranged in an overlapping manner in FIG. It is a side view. The wall structure shown in FIGS. 1 and 2 is a structure in which a plurality of flat wall materials 1 having a flat outer shape are arranged side by side on a wall base.

  Specifically, with respect to the downward direction 2 of the wall, the respective flat wall materials 1 are arranged such that their side ends are abutted against each other. Further, as particularly shown in FIG. 2, with respect to the vertical direction 3 of the wall orthogonal to the lower direction 2, each flat wall material 1 is one of the upper flat wall materials 1 on the lower flat wall material 1. The parts are placed one on top of the other.

  Further, with respect to the lower direction 2, the upper flat wall material 1 is arranged so as to be shifted from the lower flat wall material 1 by half of the extending width of the flat wall material 1 along the lower direction 2. That is, the butted portion of the side end of the upper flat plate wall material 1 is shifted from the butted portion of the side end of the lower flat plate wall material 1 with respect to the lower direction 2.

  Each flat wall member 1 is fastened to the wall base by driving a fastening member 4 such as a nail or a screw. In addition, the fastening member 4 is covered with the upper flat plate wall material 1, and only a part of the fastening members 4 is illustrated by broken lines in FIG.

  For the sake of explanation, the plurality of flat plate wall members 1 arranged side by side in the downward direction 2 may be referred to as one row of flat plate wall members 1. According to this expression, FIG. 2 shows a first row of flat wall materials 1 (1A), a second row of flat wall materials 1 (1B), and a third row of flat wall materials 1 (1C). It will be.

Further, the fastening members 4 (4C) driven into the third row of flat plate wall materials 1C pass through the second row of flat plate wall materials 1B and reach the wall base.

  Note that the terms “first row to third row” described above represent only three rows of the flat wall material 1 arranged so as to be shifted in the vertical direction 3 and limit the position of each row in the entire wall structure. Not what you want. That is, the other flat wall material 1 may be arrange | positioned under the flat wall material 1A of the 1st row.

  3 is a front view showing the flat wall material 1 of FIG. 1, FIG. 4 is a rear view showing the flat wall material 1 of FIG. 3, and FIG. 5 is a flat plate along the line IV-IV of FIG. 1 is a cross-sectional view of a wall material 1. As shown in FIGS. 3 to 5, the flat wall material 1 has a substantially rectangular outer shape in plan view having a longitudinal direction 1 </ b> L (width direction) and a short direction 1 </ b> S (depth direction). The flat wall material 1 is disposed on the wall base so that the longitudinal direction 1L is along the downward direction 2 of the wall and the short direction 1S is along the vertical direction 3 of the wall (see FIG. 1). As shown in FIGS. 3 to 5, the flat wall material 1 is a metal wall material having a front base material 12, a back base material 13, and a core material 14.

  The front substrate 12 is a metal member made of a metal plate, and is a member that appears on the outer surface of the wall when the flat wall material 1 is placed on the wall base. As particularly shown in FIG. 5, the front base material 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, the top plate 120 a of the front base material 12 is provided with a plurality of fastening holes 121 spaced apart from each other in the longitudinal direction 1 </ b> L (downward direction 2) of the flat plate wall material 1. The tightening hole 121 indicates a driving position of the tightening member 4 (see FIG. 1) into the flat plate wall material 1. In the present embodiment, the binding hole 121 is described as being provided in the front substrate 12, but for example, a non-opening mark indicating a driving position of the binding member 4 such as a printed symbol or unevenness is tightened. Instead of the hole 121, the top plate 120a may be provided.

  A first side surface 122, a second side surface 123, an upper end surface 124, and a lower end surface 125 are provided on the peripheral wall 120 b of the front substrate 12.

  The first and second side surfaces 122 and 123 are respectively provided on both sides of the flat plate wall material 1 in the longitudinal direction 1L. The second side surface 123 is adapted to be positioned above the first side surface 122 when the flat wall material 1 is disposed on the roof base. The second side surface 123 is disposed at a position that protrudes outward in the longitudinal direction 1L of the flat plate wall material 1 from the first side surface 122.

  The first side surface 122 is formed by folding a metal plate extending from the lower end of the first side surface 122 outward in the longitudinal direction 1L to the back side of the front substrate 12 so as to hold the back substrate 13. A flange 122a is provided. Since the side flange 122a is provided integrally with the main body 120, the durability (anti-resistance) of the flat wall material 1 against an external force that tries to warp the flat wall material 1 to the front side or the back side along a straight line along the longitudinal direction 1L. Wind pressure performance) is improved. The protruding width of the side flange 122 a from the first side surface 122 is set to be equal to or less than the protruding width of the second side surface 123 from the first side surface 122.

  The second side surface 123 is not provided with a flange. This is because the flange extending from the second side surface 123 is cut and removed after the box-shaped main body 120 is formed.

  The lower end surface 124 is positioned at one end along the short direction 1S, and is adapted to be positioned on the upper side when the flat wall material 1 is disposed on the wall base. The upper end surface 124 is provided with a straight portion 124a and a pair of inclined portions 124b. The straight portion 124a extends linearly along the longitudinal direction 1L. The oblique portion 124b is disposed 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 is inclined and extended with respect to the straight portion 124a so as to go downward (the other end side along the short direction 1S) as it approaches the second side surface 123.

  As shown in FIGS. 3 and 5, in the straight portion 124 a of the upper end surface 124, a metal plate extending outward from the lower end of the upper end surface 124 along the short direction 1 </ b> S holds the back base material 13. Thus, the upper side flange 124c formed by being folded back on the back side of the front substrate 12 is provided.

  The inclined portion 124b of the upper end surface 124 is not provided with a flange. This is because, like the second side surface 123 described above, the flange extending from the inclined portion 124b is cut and removed after the box-shaped main body 120 is formed. However, a flange similar to the upper flange 124c may be provided in the oblique portion 124b.

  The lower end surface 125 is positioned at the other end along the short direction 1S, and is adapted to be positioned on the lower side when the flat plate wall material 1 is disposed on the wall base. In the flat plate wall material 1 of the present embodiment, the upper and lower end surfaces 125 are constituted only by straight portions extending along the longitudinal direction 1L. However, the lower end surface 125 may have other shapes.

  The lower end surface 125 is formed by folding a metal plate extending outward from the lower end of the lower end surface 125 along the short direction 1 </ b> S to the back side of the front substrate 12 so as to hold the back substrate 13. A lower flange 125a is provided.

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

  As the metal plate which is the material of the surface base material 12, a hot-dip Zn-based plated steel plate, a hot-dip Al-plated steel plate, a hot-dip Zn-plated stainless steel plate, a hot-dip Al-plated stainless steel plate, a stainless steel plate, an Al plate, a Ti plate, and a paint-melted Zn-based plate A plated steel plate, a coated hot-dip Al-plated steel plate, a coated hot-dip Zn-based plated stainless steel plate, a painted hot-Al plated stainless steel plate, a painted stainless steel plate, a painted Al plate, or a coated Ti plate can be used. When making the front base material 12 into a box shape, it is preferable that the front base material 12 is constituted by drawing a steel plate. This is because work hardening occurs in the peripheral wall 120b by drawing the steel plate, and the wind pressure resistance of the flat wall material 1 can be improved. Moreover, it is because the surrounding wall 120b can be made into the wall surface continuous in the circumferential direction of the surface base material 12. FIG.

  The back substrate 13 is a member disposed on the back side of the front substrate 12 so as to close the opening of the main body 120. As the back substrate 13, a lightweight material 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 back base material 13, it is possible to avoid an increase in the weight of the flat wall material 1.

  The core material 14 is made of, for example, a foamed resin, and is filled between the main body 120 and the back base material 13. There is no restriction | limiting in particular as a raw material of the core material 14, A urethane, a phenol, a nurate resin etc. can be used. However, it is essential to use incombustible certified materials for roofing materials. In the incombustible material qualification test, an exothermic test based on the ISO 5660-1 cone calorimeter test method is performed. When the foamed resin to be the core material 14 is urethane or the like having a large calorific value, the thickness of the core material 14 can be reduced, or the foamed resin can contain inorganic foam particles. The core material is attached to the back surface of the front substrate 12 rather than the aspect in which the backing material such as a resin sheet is attached to the back side of the front substrate 12 by filling the foamed resin between the main body 120 and the back substrate 13. 14 can be firmly adhered, and performances required for wall materials such as rain sound property, heat insulation property, and tread resistance can be improved.

  Next, FIG. 6 is a front view showing the plate-like cover material 5 used in the wall repairing method according to the embodiment of the present invention, and FIG. 7 is a plate-like cover material along line VII-line VII of FIG. 5 is a cross-sectional view of the plate-like cover material 5 taken along line VIII-line VIII of FIG.

  The plate-shaped cover member 5 shown in FIG. 6 is damaged when one flat plate wall member 1 out of a plurality of flat plate wall members 1 arranged side by side as shown in FIG. 1 is damaged. It is for repairing 1. As will be described later with reference to the drawings, the plate-like cover material 5 is arranged so as to overlap the flat plate wall material 1 so as to cover the top plate 120a of the damaged flat plate wall material 1. In addition, in FIGS. 6-8, the flat wall material 1 with which the plate-shaped cover material 5 is piled up is represented with the dashed-two dotted line.

  The plate-like cover material 5 has a substantially rectangular outer shape in a plan view having a longitudinal direction 5L (width direction) and a short direction 5S (depth direction), like the flat plate wall material 1. The material of the plate-like cover material 5 is arbitrary, but is preferably the same material as the top plate of the flat wall material 1. As described above, when the flat wall material 1 is configured by the metal wall material in which the metal plate is used for the front substrate 12, the plate-like cover material 5 can be configured by the metal plate similarly to the front substrate 12. it can. For example, when surface treatment such as painting or uneven processing is applied to the top plate 120 a of the flat wall material 1, the same surface treatment is preferably applied to the surface of the plate-like cover material 5. The same surface treatment here refers to not only the exact same surface treatment, but also the plate-like cover material 5 when the surface base material 12 and the plate-like cover material 5 of the flat plate wall material 1 are viewed a few meters apart. The same kind of surface treatment that gives the impression that the surface of the surface of the surface substrate 12 is the same kind as the surface of the front substrate 12 is also included.

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

  As shown in FIG. 7, the side end portion 50 of the plate-like cover member 5 is provided along the top plate 120 a of the flat plate wall member 1. In other words, the side wall 50 is not provided with a vertical wall along the peripheral wall 120b of the flat plate wall material 1. Since the vertical wall is not provided at the side end portion 50, when the plate-like cover material 5 is inserted between the flat plate wall base materials 1 as will be described later, the plate-like cover material 5 follows a straight line along the longitudinal direction 5L. Can be easily bent to the front side or the back side. Note that the width of the plate-like 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 member 1 along the longitudinal direction 5L. ing.

  As shown in FIG. 8, the lower end portion 51 is provided with a vertical wall 51 a along the peripheral wall 120 b of the flat plate 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 a straight line along the short direction 5S. Moreover, the plate-shaped cover member 5 can be reliably positioned along the short direction 5S by abutting the vertical wall 51a with the peripheral wall 120b. In the present embodiment, it is described that the vertical wall 51a is provided at the lower end 51, but the vertical wall 51a may be omitted. An extension wall that holds or covers the lower flange 125a of the flat wall material 1 may be extended from the tip of the vertical wall 51a.

  The lower end portion 52 is provided with a straight portion 52a and a slant portion 52b. The straight portion 52a extends linearly along the longitudinal direction 5L. Moreover, the linear part 52a is extended in the approximate center position of the plate-shaped cover material 5 along the longitudinal direction 5L. The oblique portions 52b are 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 is inclined and extended with respect to the linear portion 52a so as to go downward as it approaches the side end portion 50.

  The width between the straight portion 52a and the lower end portion 51 along the short direction 5S is such that the lower end portion of the first row of flat wall materials 1A and the third row of flat plates along the up-down direction 3 shown in FIG. It is preferable that it is larger than the separation distance D1 between the lower end portions of the wall material 1C. With this configuration, when the plate-like cover member 5 is inserted between the first row of flat plate wall members 1A and the second row of flat plate wall members 1B, it is covered by the third row of flat plate wall members 1C. The plate-shaped cover material 5 can be extended below the butted portion of the side edge of the second row of flat plate wall materials 1B that are not hidden (see FIG. 10). Thereby, it is possible to avoid moisture entering from the abutting portion of the side edge of the second row of flat plate wall members 1B from entering between the plate-like cover member 5 and the first row of flat plate wall members 1A.

  The upper end portion 52 is provided with a water return portion 52c in which a plate material constituting the plate-like cover material 5 is folded from the back surface side to the front surface side. By providing the water return portion 52c in the upper end portion 52, moisture entering from the abutting portion of the side end of the second row of flat wall materials 1B exceeds the upper end portion 52 and the plate-like cover material 5 and the first row. It is possible to avoid entering the flat wall material 1A.

  The fastening member 4B driven into the flat wall member 1B in the second row passes through the lower end of the flat wall member 1A in the first row. When the width between the straight portion 52a and the lower end portion 51 along the short direction 5S is increased, the fastening member 4B driven into the second row of the flat wall material 1B and the plate-like cover material 5 may interfere with each other. Increases nature. As described above, the inclined portion 52b is provided in the upper end portion 52, thereby reducing the possibility that the fastening member 4B driven into the second row of flat plate wall materials 1B and the plate-like cover material 5 interfere with each other. it can.

  Next, a wall repair method according to an embodiment of the present invention will be described. Note that the wall repair method of the present embodiment corresponds to a method of manufacturing a repaired wall structure. FIG. 9 is an explanatory view showing a wall repair method according to an embodiment of the present invention, and FIG. 10 is an explanatory view showing a wall structure to which the wall repair method of FIG. 9 is applied.

  As shown in FIG. 9, the second row of flat plate wall materials 1 </ b> B is arranged above the first row of flat plate wall materials 1 </ b> A, and the third row of flat plate wall materials 1 </ b> C is located above the second row of flat plate wall materials 1 </ b> B. In the arranged wall structure, it is assumed that the top plate of the flat wall material 1A in the first row is damaged. At this time, the plate-like cover material 5 is inserted between the first row of flat plate wall materials 1A and the second row of flat plate wall materials 1B (between the lower flat plate wall material and the upper flat plate wall material), As shown in FIG. 10, the top plate 120 a of the flat wall material 1 </ b> A in the first row is covered with the plate-shaped cover material 5. As a result, the top plate 120a can be repaired while leaving the damaged first-row flat plate wall material 1A. That is, it is possible to save time and labor associated with cutting the fastening members that fasten the first row of flat plate wall materials 1A and withdrawing the first row of flat wall materials 1A. This configuration is particularly useful when the fastening member 4B driven into the second row of flat wall materials 1B also penetrates the first row of flat wall materials 1A.

  Before inserting the plate-shaped cover material 5, apply an adhesive to the back surface of the plate-shaped cover material 5, and after inserting the plate-shaped cover material 5, bond the plate-shaped cover material 5 to the flat wall material 1 </ b> A in the first row. Can do. Alternatively, for example, a binding member such as a nail or a screw may be driven into the plate-shaped cover material 5 after the plate-shaped cover material 5 is inserted, so that the plate-shaped cover material 5 is bonded to the wall base. Either one or both of the bonding and binding of the plate-like cover material 5 may be performed.

  In the insertion of the plate-shaped cover material 5, the vertical wall 51a (see FIG. 8) provided at the lower end 51 of the plate-shaped cover material 5 is in contact with or close to the peripheral wall 120b of the flat plate wall material 1A in the first row. Is done. When the plate-shaped cover material 5 is inserted, the side wall 50 of the plate-shaped cover material 5 is not provided with a vertical wall along the peripheral wall 120b of the flat plate wall material 1, so that the plate is aligned along a straight line along the longitudinal direction 5L. The cover material 5 can be warped.

  As shown in FIG. 10, in the state in which the plate-like cover member 5 is inserted between the first row of flat plate wall members 1A and the second row of flat plate wall members 1B, the third row of flat plate wall members 1C A plate-like cover material 5 extends below the lower end. Thereby, it is possible to avoid moisture entering from the abutting portion of the side edge of the second row of flat plate wall members 1B from entering between the plate-like cover member 5 and the first row of flat plate wall members 1A.

  According to such a wall repair method and its wall structure, the top cover 120a of the lower flat plate wall material 1 is covered with the plate-like cover material 5, so that the trouble of cutting the fastening member 4 can be saved and the damage can be avoided. The flat plate wall material 1 can be repaired more efficiently. This configuration is particularly useful when the flat wall material 1 is constituted by a metal wall material having the front substrate 12, the back substrate 13 and the core member 14.

  Moreover, since the plate-shaped cover material 5 is comprised with the metal plate similarly to the surface base material 12, it can avoid that the plate-shaped cover material 5 stands out by the difference with the surrounding flat plate wall material 1. FIG.

  Further, the plate-like cover member 5 inserted between the first row of flat plate wall members 1A and the second row of flat plate wall members 1B extends below the lower end of the third row of flat plate wall members 1C. Therefore, it is possible to avoid moisture entering from the abutting portion of the side end of the second row of flat plate wall materials 1B from entering between the plate-like cover material 5 and the first row of flat plate wall materials 1A. it can.

  Furthermore, the upper end portion of the plate-shaped cover material 5 is provided with a water return portion 52c in which the plate material constituting the plate-shaped cover material 5 is folded from the back surface side to the front surface side. It is possible to avoid that water entering from the abutting portion of the side end of the wall material 1B exceeds the upper end portion 52 and enters between the plate-like cover material 5 and the first row of flat wall materials 1A.

  Moreover, since the side edge part of the plate-shaped cover material 5 is provided so that the top plate of a flat wall material may be followed, the plate-shaped cover material 5 can be warped along the straight line along the longitudinal direction 5L, and the 1st The plate-like cover material 5 can be inserted more efficiently between the one row of flat plate wall materials 1A and the second row of flat plate wall materials 1B.

  Furthermore, since the vertical wall 51a along the peripheral wall 120b of the flat plate wall material 1 is provided at the lower end portion of the plate-shaped cover material 5, the plate-shaped cover material 5 warps along a straight line along the short direction 5S. In addition to improving the yield strength, the plate-like cover material 5 can be reliably positioned along the short direction 5S.

  Furthermore, since the plate-shaped cover material 5 is bonded to the top plate 120 a of the lower flat plate wall material 1, it is possible to avoid the plate-shaped cover material 5 from being detached from the flat plate wall material 1.

  Further, since the plate-like cover material 5 is tightly coupled to the wall base together with the lower flat plate wall material 1, it is possible to avoid the plate-like cover material 5 from being detached from the flat plate wall material 1.

  In addition, in embodiment, although the flat wall material 1 is demonstrated with the metal wall material which has the front base material 12, the back base material 13, and the core material 14, for example, ceramics systems, such as a slate roof tile The present invention can also be applied to a case where a flat plate wall material is constituted by the wall material.
