How to repair the wall and its wall structure

The present invention relates to a wall repair method and a wall structure for repairing a wall in which a plurality of flat wall materials are arranged so that a part of the upper flat wall material overlaps on the surface of the lower flat wall material. ..

The present inventors have a metal wall material as shown in Patent Document 1 below, that is, a metal front base material, a back base material arranged on the back side of the front base material, and a front base material and a back side. We are trying to put into practical use a metal wall material provided with a core material made of foamed resin filled between the base material and the base material. After being placed on the surface of the wall base, such a metal wall material is bound to the wall base by driving a binding member such as a nail or a screw.

As a method for repairing face materials such as roofing materials and wall materials of this kind that have been conventionally used, for example, the method shown in Patent Document 2 and the like below can be mentioned. That is, in the conventional method, one flat roof material is damaged in a roof in which a plurality of flat roof materials are arranged so that a part of the flat roof material on the ridge side overlaps on the surface of the flat roof material on the eave side. Occasionally, the flat roofing material is removed. Specifically, a fitting is inserted between the extracted roofing material to be extracted and the roofing material arranged on the eaves side of the extracted roofing material, and the extracted roofing material is tied to the roof base, for example, a nail. After cutting the binding member such as a screw, the extracted roofing material is extracted. Patent Document 2 is for a flat roof material, but it is necessary to repair the flat wall material in the same manner.

It is explanatory drawing which shows the wall structure to which the wall repair method of FIG. 9 is applied.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
Embodiment FIG. 1 is a front view showing a wall structure before repair to which the wall repair method according to the embodiment of the present invention is applied, and FIG. 2 is a front view showing three flat plate wall materials arranged in an overlapping manner in FIG. It is a side view which shows. In the wall structure shown in FIGS. 1 and 2, a plurality of flat plate wall materials 1 having a flat plate-like outer shape are arranged side by side on the surface of the wall base.

Specifically, with respect to the horizontal direction 2 (horizontal direction) of the wall, each flat plate wall material 1 is arranged so that its side ends are abutted against each other. Further, as particularly shown in FIG. 2, with respect to the vertical direction 3 (vertical direction) of the wall orthogonal to the left-right direction 2, each flat plate wall material 1 is an upper flat plate on the surface of the lower flat plate wall material 1. A part of the wall material 1 is overlapped and arranged.

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

Each flat plate wall material 1 is bound to the wall base by driving a binding member 4 such as a nail or a screw, for example. The binding member 4 is covered by the upper flat plate wall material 1, and in FIG. 1, only a part of the binding member 4 is shown by a broken line.

For the following explanation, a plurality of flat plate wall materials 1 arranged side by side in the left-right direction 2 may be referred to as a row of flat plate wall materials 1. According to this expression, FIG. 2 shows the flat plate wall material 1 (1A) in the first row, the flat plate wall material 1 (1B) in the second row, and the flat plate wall material 1 (1C) in the third row. It will be. The second row of flat wall material 1B is arranged above the first row of flat wall material 1A, and the third row of flat wall material 1C is arranged above the second row of flat wall material 1B. The binding member 4 (4B) driven into the flat plate wall material 1B in the second row penetrates the flat plate wall material 1A in the first row and reaches the wall base. Further, the binding member 4 (4C) driven into the flat plate wall material 1C in the third row penetrates the flat plate wall material 1B in the second row and reaches the wall base.

In addition, the above-mentioned terms of the first row to the third row merely represent three rows of the flat plate wall material 1 arranged so as to be shifted in the vertical direction 3, and the position of each row in the entire wall structure is limited. It's not something to do. That is, another flat plate wall material 1 may be arranged below the flat plate wall material 1A in the first row.

Next, FIG. 3 is a front view showing the flat plate wall material 1 of FIG. 1, FIG. 4 is a rear view showing the flat plate wall material 1 of FIG. 3, and FIG. 5 is a flat plate along line VV of FIG. It is sectional drawing of the wall material 1. As shown in FIGS. 3 to 5, the flat plate wall material 1 has a substantially rectangular outer shape in the front view having 1 L in the longitudinal direction (width direction) and 1 S in the lateral direction (height direction). The flat plate wall material 1 is arranged on the surface of the wall base so that the longitudinal direction 1L is along the horizontal direction 2 of the wall and the lateral direction 1S is along the vertical direction 3 of the wall (see FIG. 1). As shown in FIGS. 3 to 5, the flat plate 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 surface base material 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 plate wall material 1 is arranged on the surface of the wall base. As particularly shown in FIG. 5, the surface base material 12 is provided with a box-shaped main body 120 having a top plate 120a and a peripheral wall 120b.

As shown in FIG. 3, the top plate 120a of the surface base material 12 is provided with a plurality of binding holes 121 separated from each other in the longitudinal direction 1L (horizontal direction 2) of the flat plate wall material 1. The binding hole 121 indicates the driving position of the binding member 4 (see FIG. 1) into the flat plate wall material 1. In the present embodiment, it is explained that the binding hole 121 is provided on the surface base material 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 bound. It may be provided in the top plate 120a instead of the hole 121.

The peripheral wall 120b of the surface base material 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 and second side surfaces 122 and 123 are provided on both sides of the flat plate wall material 1 in the longitudinal direction 1L, respectively. The second side surface 123 is adapted so that when the flat plate wall material 1 is placed on the surface of the wall base, it is located above the first side surface 122. The second side surface 123 is arranged at a position protruding outward in the longitudinal direction 1L of the flat plate wall material 1 from the first side surface 122.

On the first side surface 122, a side surface formed by folding back a metal plate extending outward in the longitudinal direction 1L from the tip of the first side surface 122 to the back side of the front base material 12 so as to hold the back base material 13. A flange 122a is provided. Since the side flange 122a is provided integrally with the main body 120, the durability (resistance) of the flat plate wall material 1 against an external force that tends to warp the flat plate wall material 1 toward the front side or the back side along a straight line along the longitudinal direction 1L. Wind pressure performance) has been improved. The protruding width of the side flange 122a from the first side surface 122 is 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 upper end surface 124 is located at one end along the lateral direction 1S, and is adapted so as to be located on the upper side when the flat plate wall material 1 is arranged on the surface of the wall base. The upper end surface 124 is provided with a straight portion 124a and a pair of oblique portions 124b. The straight portion 124a extends linearly 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. Further, the inclined portion 124b is inclined and extends with respect to the straight portion 124a so as to approach the second side surface 123 toward the lower side (the other end side along the lateral direction 1S).

As particularly shown in FIGS. 3 and 5, a metal plate extending outward from the tip of the upper end surface 124 along the lateral direction 1S holds the back base material 13 in the straight portion 124a of the upper end surface 124. An upper flange 124c formed by being folded back on the back side of the front base material 12 is provided.

No flange is provided on the inclined portion 124b of the upper end surface 124. This is because, similarly to 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 portion 120 is formed. However, a flange similar to 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 lateral direction 1S, and is adapted so as to be located on the lower side when the flat plate wall material 1 is arranged on the surface of the wall base. In the flat plate wall material 1 of the present embodiment, the lower end surface 125 is composed of only a straight portion extending along the longitudinal direction 1L. However, the lower end face 125 may have other shapes.

The lower end surface 125 is formed by a metal plate extending outward from the tip of the lower end surface 125 along the lateral direction 1S and folded back to the back side of the front base material 12 so as to hold the back base material 13. A lower flange 125a is provided.

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

The metal plate that is the material of the table base material 12 includes a molten Zn-based plated steel sheet, a molten Al-plated steel sheet, a molten Zn-based plated stainless steel sheet, a molten Al-plated stainless steel sheet, a stainless steel sheet, an Al plate, a Ti plate, and a painted molten Zn-based steel sheet. A plated steel sheet, a painted molten Al plated steel sheet, a painted molten Zn-based plated stainless steel sheet, a painted molten Al plated stainless steel sheet, a painted stainless steel sheet, a painted Al plate or a painted Ti plate can be used. When the table base material 12 has a box shape, it is preferable to draw the steel plate to form the table base material 12. This is because work hardening occurs in the peripheral wall 120b by drawing the steel plate, and the wind pressure resistance performance of the flat plate wall material 1 can be improved. Further, the peripheral wall 120b can be a wall surface continuous in the circumferential direction of the surface base material 12.

The back base material 13 is a member arranged on the back side of the front base material 12 so as to close the opening of the main body 120. As the backing base material 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 backing base material 13, it is possible to avoid an increase in the weight of the flat plate 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 backing base material 13. The material of the core material 14 is not particularly limited, and urethane, phenol, nurate resin and the like can be used. However, it is essential to use non-combustible certified materials for wall materials. In the non-combustible material certification test, a heat generation test based on the ISO5660-1 cone calorimeter test method is carried out. 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 foamed particles. By filling the foam resin between the main body 120 and the back base material 13, the core material is attached to the back surface of the front base material 12 rather than the backing material such as a resin sheet is attached to the back side of the front base material 12. 14 can be firmly adhered to each other, and the performance required for the wall material such as rain noise property, heat insulating property and trampling resistance can be improved.

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

The plate-shaped cover material 5 shown in FIG. 6 is a damaged flat plate wall material when one of the plurality of flat plate wall materials 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-shaped cover material 5 is arranged on 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 to 8, the flat plate wall material 1 on which the plate-shaped cover material 5 is superposed is represented by a two-dot chain line. In the plate-shaped cover material 5, when the plate-shaped cover material 5 covers the top plate of the flat plate wall material 1 (lower flat plate wall material 1), the outer edge of the plate-shaped cover material 5 is the outer edge of the flat plate wall material 1. It has an outer shape that fits inside.

Similar to the flat plate wall material 1, the plate-shaped cover material 5 has a substantially rectangular outer shape in a plan view having a longitudinal direction of 5L (width direction) and a lateral direction of 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 plate wall material 1. When the flat plate wall material 1 is composed of the metal wall material in which the metal plate is used for the surface base material 12 as described above, the plate-shaped cover material 5 may be composed of the metal plate as in the surface base material 12. it can. For example, when surface treatment such as painting or uneven processing is applied to the top plate 120a of the flat plate wall material 1, it is preferable that the same surface treatment is applied to the surface of the plate-shaped cover material 5. The same surface treatment referred to here is not limited to exactly the same surface treatment, but when the surface base material 12 of the flat plate wall material 1 and the plate-shaped cover material 5 are viewed at a distance of about several m, the plate-shaped cover material 5 is used. Also included is the same type of surface treatment that gives the impression that the surface of the surface is not clearly different from the surface of the surface base material 12 and is of the same type.

The plate-shaped 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-shaped cover material 5 is provided along the top plate 120a of the flat plate wall material 1. In other words, the side end portion 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-shaped cover material 5 is inserted between the flat plate wall materials 1 as described later, the plate-shaped cover material 5 is formed along a straight line along the longitudinal direction 5L. It can be easily warped to the front or back side. The width of the plate-shaped cover material 5 along the longitudinal direction 5L is equal to the width of the top plate 120a of the flat plate wall material 1 along the longitudinal direction 5L, or slightly smaller than the width of the top plate 120a. ing.

As shown in FIG. 8, the lower end portion 51 is provided with a vertical wall 51a along the peripheral wall 120b (lower end surface 125) of the flat plate wall material 1. By providing the vertical wall 51a on the lower end portion 51, it is possible to prevent the plate-shaped cover material 5 from warping along a straight line along the lateral direction 5S. Further, by abutting the vertical wall 51a against the peripheral wall 120b, the plate-shaped cover material 5 can be reliably positioned along the lateral direction 5S. When the plate-shaped cover material 5 covers the top plate 120a of the flat plate wall material 1 (lower flat plate wall material), the lower flange 125a extends outward from the lower part of the vertical wall 51a. Although it is described that the vertical wall 51a is provided at the lower end portion 51 in the present embodiment, the vertical wall 51a may be omitted. Further, an extension wall that holds or covers the lower flange 125a of the flat plate wall material 1 may extend from the tip of the vertical wall 51a.

The upper end portion 52 is provided with a straight portion 52a and an oblique portion 52b. The straight portion 52a extends linearly along the longitudinal direction 5L. Further, the straight portion 52a extends at 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. Further, the inclined portion 52b is inclined and extends with respect to the straight portion 52a so as to go downward as it approaches the side end portion 50.

The width between the straight portion 52a along the lateral direction 5S and the lower end portion 51 is the lower end portion of the flat plate wall material 1A in the first row and the flat plate in the third row along the vertical direction 3 shown in FIG. It is preferably larger than the separation distance D1 from the lower end portion of the wall material 1C. With this configuration, when the plate-shaped cover material 5 is inserted between the flat plate wall material 1A in the first row and the flat plate wall material 1B in the second row, it is covered by the flat plate wall material 1C in the third row. The plate-shaped cover material 5 can be extended below the butt portion of the side end of the flat plate wall material 1B in the second row that is not hidden (see FIG. 10). As a result, it is possible to prevent moisture entering from the abutting portion of the side end of the flat plate wall material 1B in the second row from entering between the plate-shaped cover material 5 and the flat plate wall material 1A in the first row.

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

The binding member 4B driven into the flat plate wall material 1B in the second row penetrates through the lower end of the flat plate wall material 1A in the first row. If the width between the straight portion 52a and the lower end portion 51 along the lateral direction 5S is widened, the binding member 4B driven into the flat plate wall material 1B in the second row and the plate-shaped cover material 5 may interfere with each other. The sex becomes high. By providing the inclined portion 52b at the upper end portion 52 as described above, the possibility that the binding member 4B driven into the flat plate wall material 1B in the second row and the plate-shaped cover material 5 interfere with each other can be reduced. it can.

Next, a method of repairing the wall according to the embodiment of the present invention will be described. The wall repair method of the present embodiment corresponds to the method of manufacturing the repaired wall structure. FIG. 9 is an explanatory view showing a wall repair method according to the 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 wall material 1B is arranged above the first row of flat wall material 1A, and the third row of flat wall material 1C is placed above the second row of flat wall material 1B. In the arranged wall structure, it is assumed that the top plate of the flat plate wall material 1A in the first row is damaged. At this time, the plate-shaped cover material 5 is inserted between the flat plate wall material 1A in the first row and the flat plate wall material 1B in the second row (between the lower flat plate wall material and the upper flat plate wall material). As shown in FIG. 10, the plate-shaped cover material 5 covers the top plate 120a of the flat plate wall material 1A in the first row. As a result, the top plate 120a can be repaired while leaving the damaged flat plate wall material 1A in the first row. That is, it is possible to save the trouble of cutting the binding member that binds the flat plate wall material 1A in the first row and extracting the flat plate wall material 1A in the first row. This configuration is particularly useful when the binding member 4B driven into the flat plate wall material 1B in the second row also penetrates the flat plate wall material 1A in the first row.

Before inserting the plate-shaped cover material 5, an adhesive is applied to the back surface of the plate-shaped cover material 5, and after inserting the plate-shaped cover material 5, the plate-shaped cover material 5 is adhered to the flat plate wall material 1A in the first row. Can be done. Further, for example, a binding member such as a nail or a screw may be inserted into the plate-shaped cover material 5 and then driven into the plate-shaped cover material 5 to bind the plate-shaped cover material 5 to the wall base. Either one or both of the plate-shaped cover material 5 may be adhered and bound.

When inserting the plate-shaped cover material 5, the vertical wall 51a (see FIG. 8) provided at the lower end portion 51 of the plate-shaped cover material 5 abuts or approaches the peripheral wall 120b of the flat plate wall material 1A in the first row. Will be done. When the plate-shaped cover material 5 is inserted, the side end portion 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 formed along a straight line along the longitudinal direction 5L. The shape cover material 5 can be warped.

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

According to such a wall repair method and its wall structure, since the plate-shaped cover material 5 covers the top plate 120a of the lower flat plate wall material 1, it is possible to save the trouble of cutting the binding member 4 and damage it. The flat plate wall material 1 can be repaired more efficiently. This configuration is particularly useful when the flat plate wall material 1 is composed of a metal wall material having a front base material 12, a back base material 13, and a core material 14.

Further, in the plate-shaped cover material 5, when the plate-shaped cover material 5 covers the top plate 120a of the lower flat plate wall material 1, the outer edge of the plate-shaped cover material 5 is inside the outer edge of the lower flat plate wall material 1. Since it has an outer shape that fits in, a specific wall material can be repaired without changing the appearance of the wall surface.

Further, since the plate-shaped cover material 5 is made of a metal plate like the surface base material 12, it is possible to prevent the plate-shaped cover material 5 from being conspicuous due to the difference from the surrounding flat plate wall material 1.

Further, the plate-shaped cover material 5 inserted between the flat plate wall material 1A in the first row and the flat plate wall material 1B in the second row extends below the lower end portion of the flat plate wall material 1C in the third row. Since it is present, it is possible to prevent moisture entering from the abutting portion of the side end of the flat plate wall material 1B in the second row from entering between the plate-shaped cover material 5 and the flat plate wall material 1A in the first row. it can.

Further, since the water return portion 52c in which the plate material constituting the plate-shaped cover material 5 is folded back from the back surface side to the front surface side is provided at the upper end portion of the plate-shaped cover material 5, the flat plate wall of the second row is provided. It is possible to prevent the moisture entering from the abutting portion of the side end portion of the material 1B from exceeding the upper end portion 52 and entering between the plate-shaped cover material 5 and the flat plate wall material 1A in the first row.

Further, since the side end portion of the plate-shaped cover material 5 is provided along the top plate of the flat plate wall material, the plate-shaped cover material 5 can be warped along a straight line along the longitudinal direction 5L. The plate-shaped cover material 5 can be inserted more efficiently between the flat plate wall material 1A in the first row and the flat plate wall material 1B in the second row.

Further, since the vertical wall 51a along the peripheral wall 120b of the flat plate wall material 1 is provided at the lower end of the plate-shaped cover material 5, the plate-shaped cover material 5 warps along a straight line along the lateral direction 5S. In addition to improving the proof stress, the plate-shaped cover material 5 can be reliably positioned along the lateral direction 5S.

Further, since the vertical wall is along the lower end surface, the plate-shaped cover material 5 can be reliably positioned along the lateral direction 5S.

Further, since the plate-shaped cover material 5 is adhered to the top plate 120a of the lower flat plate wall material 1, it is possible to prevent the plate-shaped cover material 5 from coming off from the flat plate wall material 1.

Further, since the plate-shaped cover material 5 is tied to the wall base together with the lower flat plate wall material 1, it is possible to prevent the plate-shaped cover material 5 from coming off from the flat plate wall material 1.

In the embodiment, it is described that the flat plate wall material 1 is composed of the metal wall material having the front base material 12, the back base material 13, and the core material 14, but for example, a ceramic system such as a slate roof tile.
