Patent Document 1 discloses an example of a fixture used to perform such repairs from the exterior side of an exterior wall. In Patent Document 1, the damaged wall panel (drywall material) is removed, a fixture is fixed to the column-shaped wall base, a separate fixture is fixed to the part of the new wall panel that will be fixed with screws, the new wall panel and the existing wall panel above it are temporarily joined in a V-shape and pushed together to engage the fixtures, the new wall panel is fitted into the repaired area, and the new wall panel is fixed inseparably to the wall base. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 3827689 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, for example, metal siding has become more common, with flat decorative surfaces, making it easier for unevenness on the wall substrate to affect the finish and overall appearance of the exterior wall.However, compared to existing wall panels, new wall panels repaired using the repair structure described in the examples of Patent Document 1 have fixtures interposed between the wall substrate and the new wall panel, and thick fixtures can cause unevenness and impair the appearance of the exterior wall. [Means for solving the problem]

[0005] In order to solve these problems, the present invention provides a repair method for replacing drywall materials using a repair fixture on an exterior wall where drywall materials having a male-female connection structure are connected adjacently in the vertical direction. The repair fixture is made up of two parts: a base material fixture and a wall material fixture. The base material fixture has a rectangular flat bottom, an installation part where one side of the bottom is raised at a right angle, a bent guide part that extends from the tip of the installation part and further extends at a right angle in the opposite direction to the installation part, and a central part on the installation part side of the bottom that is perpendicular to the bottom surface. and a first engaging portion erected from the installation portion across the width of the bottom in the direction in which the replacement drywall material is attached to the existing exterior wall. Furthermore, at the boundary of the bending guide portion extending from the installation portion, a cutting groove portion is provided on the surface opposite the bottom that extends across the width of the bending guide portion. The wall material attachment fixture has a rectangular, flat base portion, a folded portion extending from one side of the base portion and folded back approximately parallel to the base portion with a gap, and a second engaging portion erected across the entire width of the base portion in the opposite direction to the folded portion so as to be parallel to the side on which the folded portion of the base portion is located. The wall material attachment fixture is used to attach a replacement drywall material to an existing exterior wall. The base material fixture is positioned by aligning it with a corner of the base material so that the bending guide portion is in contact with the front side of the base material when viewed from the outdoor side and the installation portion is in contact with the side of the base material, and the installation portion is fixed to the side of the base material with a fixture, and then the bending guide portion is bent and cut from the cutting groove portion, and the wall material fixture is fixed with a fixture so that the base portion is in contact with the indoor side of the new drywall material and the male end of the new drywall material is in contact with the back of the folded portion, and the new drywall material is then attached to the removed drywall and then tilting the upper side of the new drywall material toward the outdoors, tilting the lower side of the existing drywall material above the removed drywall material toward the outdoors and temporarily joining it to the new drywall material in a V-shape when viewed from the side, and then pushing it toward the indoor side to connect the new drywall material to the existing drywall material above in a male-female manner, and engaging a first engaging portion of a base material fixture fixed to the base material with a second engaging portion of a wall material fixture fixed to the new drywall material, thereby attaching the new drywall material. [Effects of the Invention]

[0006] According to the drywall material repair method of the present invention, unevenness is not caused by the fixtures used during repair, so poor finish of the exterior wall appearance due to unevenness caused by repair fixtures does not occur. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION [Example]

[0008] An embodiment of the repair method for drywall materials according to the present invention will be described below with reference to the drawings.

[0009] As shown in Figure 1, the repair fixture P used in the repair method for drywall material 1 of the present invention consists of two parts, a base material fixture 10 (Figure 1(a)) and a wall material fixture 30 (Figure 1(b)), and is used to fix new drywall material 1A to base material 2 such as furring strips when replacing damaged drywall material 1 with new drywall material 1A in an exterior wall where drywall materials 1 having a male-female connection structure are connected side by side. Note that the base material fixture 10 and wall material fixture 30 are preferably made of metal such as aluminum, but are not limited to this.

[0010] The drywall material 1 that constitutes the exterior wall is rectangular and has a male-female connecting structure. It is fixed to a base material 2 such as a furring strip by fasteners 3, and is connected and installed adjacent to each other in the vertical direction of the exterior wall surface.

[0011] An example of drywall material 1 is metal siding as shown in Figure 2. Figure 2(a) is a side view of metal siding, and Figure 2(b) is an enlarged view of the male-female connecting portion of the metal siding. Metal siding is a long panel with a core material sandwiched between a metal surface material and a backing material, and has male-female connecting structures at opposing longitudinal ends. Fixing pieces 1B on the male side are fixed to furring strips (underlayment material 2) with fasteners 3 such as nails or screws, connecting adjacent metal sidings to form an exterior wall. Drywall material 1 can be any material as long as it has a male-female connecting structure, and can also be plastic siding or molded metal thin plates.

[0012] The repair method for the drywall material 1 of the present invention will now be described in detail. In an exterior wall in which drywall materials 1 with a male-female connection structure are connected next to each other, if damage such as scratches or dents occurs, it becomes necessary to replace and repair the damaged drywall material 1. Horizontally laid drywall material 1 (Fig. 2(a)), which is connected and constructed in the vertical direction of the exterior wall surface, has a connection structure with a male type 1C at the top and a female type 1D at the bottom, and is equipped with a fixing piece 1B on the upper side of the drywall material 1. The fixing piece 1B part of the drywall material 1 is fixed to the wall base material with fixings 3 such as nails or screws, and the next drywall material 1 is connected male-female to the top, and this process is repeated in order to construct the exterior wall.

[0013] The damaged drywall material 1 is removed from such an exterior wall (Fig. 3(a)). The damaged drywall material 1 is destroyed and removed together with the fasteners 3 that held the drywall material 1 in place. In the space created by the removal, a base material mounting fixture 10 is fixed to the furring strip (base material 2) from the exterior side. As will be described later, Fig. 3(b) shows the state after a portion of this base mounting fixture (bending guide portion 13) has been bent and cut. Next, new drywall material 1A is prepared, and a wall material fixture 30 is fixed to the inside (indoor side) of fixing piece 1B at the top of new drywall material 1A, and it is connected to the existing drywall material 1 that was below the removed drywall material 1, and the top side of new drywall material 1A is tilted toward the outdoors, and the bottom side of the existing drywall material 1 that was above the removed drywall material 1 is tilted toward the outdoors to temporarily join it to the new drywall material 1A in a V-shape when viewed from the side, and then it is pushed toward the indoor side as shown by the arrow (Figure 3(c)). The new drywall material 1A and the existing drywall material 1 above are connected male and female, and the wall material fixture 30 fixed to new drywall material 1A is engaged with the base material fixture 10 fixed to the furring strip (base material 2), and the new drywall material 1A is fixed to the furring strip (base material 2) (Figure 3(d)). By fixing the new drywall material 1A with this repair fixture P, the new drywall material 1A does not come off the furring strip (base material 2), resulting in a strong attachment that can withstand wind pressure on the exterior wall.

[0014] Figure 4 shows the state of use of the base material fixture 10, with Figure 4(a) showing the state before the bending guide portion 13 is cut, and Figure 4(b) showing the state after the bending guide portion 13 has been cut. Figure 4(a) shows the state in which the base material fixture 10 has been fixed to the base material 2, and is a view of the base material fixture 10 from the installation portion 12 side. Figure 4(b) shows the state in which the bending guide portion 13 of the base material fixture 10 has subsequently been cut. Figure 5 shows the state in which the base material fixture 10 and wall material fixture 30 are used, with Figure 5(a) showing the state in which the wall material fixture 30 is fixed to the new drywall material 1A and the state before the wall material fixture 30 and base material fixture 10 are engaged. Figure 5(b) shows the state after the wall material fixture 30 and base material fixture 10 have engaged. Note that the existing drywall material 1 that is connected to the top of the new drywall material 1A is not shown.

[0015] Next, examples of the base material fixture 10 and the wall material fixture 30 that constitute the repair fixture P according to the present invention will be specifically described with reference to the drawings. The base material mounting fixture 10 is fixed to the furring strip (base material 2), and as shown in Figure 1(a), has a bottom 11, an installation portion 12, a bending guide portion 13, and a first engagement portion 14, and the bending guide portion 13 is provided with a cutting groove portion 15 and a cutting preparation groove portion 16.

[0016] The bottom 11 is in the shape of a rectangular flat plate. The installation section 12 is rectangular with one side of the bottom 11 raised at a right angle, and serves as the section for fixing the base material fixture 10 to the furring strip, and is fixed to the side of the furring strip (when viewed from the outside) with fixing devices 3 such as screws. Holes 22 for the fixing devices 3 may be provided in the installation section 12.

[0017] The bending guide portion 13 extends from the tip edge of the raised installation portion 12, and a cutting groove portion 15 is formed in the extending portion on the surface opposite the bottom portion 11, with the tip of the cutting groove portion 15 extending further and bent at a right angle toward the cutting groove portion 15. The base material fixture 10 is fixed to the furring strip by aligning the right angle portion of the bending guide portion 13 with the corner of the furring strip so that the bending guide portion 13 is located on the front side of the furring strip and the installation portion 12 is located on the side side of the furring strip when viewed from the outdoors. This fixes the base material fixture 10 at a fixed distance from the outdoors surface of the furring strip toward the indoor side, ensuring stable engagement between the base material fixture 10 and the wall material fixture 30 without any variation.

[0018] The cutting groove 15 is provided at the boundary with the installation section 12, running continuously from end to end of the bending guide section 13, parallel to the direction in which the bottom surface 11 and the installation section 12 intersect. This cutting groove 15 allows the bending guide section 13 to be cut along the cutting groove 15 when the base material fixture 10 is secured to the furring strip and then bent. When two base material fixtures 10 are provided spaced apart as shown in FIG. 1(a), for ease of fastening, the upper bending guide section 13 may be bent and cut before the base material fixture 10 is secured to the base material 2, and then the lower bending guide section 13 may be bent and cut. By cutting the bending guide section 13 extending from the installation section 12, the remaining cut portion of the base material fixture 10 becomes linear. After being cut from the cutting groove 15, the base material fixture 10 is positioned on the side of the furring strip when viewed from the outside, and the position of the base material fixture 10 in the indoor / outdoor direction is such that no portion of it protrudes outdoors from the outdoor surface of the furring strip. Because the wall material fixture 30 is positioned to engage with the base material fixture 10 fixed to the side of the furring strip in the outdoor direction, when the base material fixture 10 and the wall material fixture 30 are used to fix the new drywall material 1A to the furring strip, the fixture will not be sandwiched between the new drywall material 1A and the furring strip, and unevenness F caused by the fixture will not occur in the new drywall material 1A portion.

[0019] The cutting preparation groove 16 is provided on the surface on the 270-degree side of the right-angle bent portion of the bending guide portion 13. When the bending guide portion 13 is raised, bent, and cut, if this cutting preparation groove 16 is not provided, the cutting will occur from the right-angle bent portion of the bending guide portion 13 or from the cutting groove portion 15. By providing this cutting preparation groove 16, cutting can be stably performed from the cutting groove portion 15.

[0020] The first engagement portion 14 has two raised portions 18 spaced apart from the approximate center of the bottom portion 11, and engagement claws 20 at the tips of the raised portions 18. The two raised portions 18 are continuous across the width and face each other in parallel. In FIG. 1(a), both long sides of a rectangular central piece are raised to form a generally U-shaped cross section with an open upper portion, and this is then clinched 19 to the bottom portion 11. Although FIG. 1(a) shows linear raised portions facing each other, it is also possible for arc-shaped raised portions to face each other. The first engagement portion 14 engages with a second engagement portion 33 of a wall material fixture 30, which will be described later.

[0021] In addition, in Figure 1(a), the first engagement portion 14 is located approximately in the center of the bottom portion 11, with multiple holes 22 for fasteners 3 on both sides. When attaching to a furring strip, the furring strip fixture 10 is attached to either the left or right side of the furring strip when viewed from the exterior. However, when damaged drywall material 1 is removed from the exterior wall surface and the resulting space is used to attach the furring strip fixture 10 to the side of the furring strip from the exterior side, there are cases where the fixture can only be attached to the right or left side of the furring strip, such as a furring strip at the edge of the space. In such cases, the furring strip fixture 10 can be attached to either the left or right side of the furring strip by flipping it 180 degrees up and down. The furring strip fixture 10 is attached to the furring strip at the top of the space created by the damaged and removed drywall material 1. Regardless of which side of the furring strip the base material mounting fixture 10 is fixed to, it can be fixed by the fixing fixture 3 through the hole 22 for the fixing fixture 3 on the underside of the first engagement portion 14, making installation easy.

[0022] The bottom 11 may also be provided with side reinforcing pieces 17 that reinforce the strength so that the angle between the bottom 11 and the installation section 12 does not widen, i.e., so that the position of the first engagement section 14 that engages with the second engagement section 33 does not move. In Fig. 1(a), both end sides of the bottom 11 are raised and the side toward the installation section 12 is bent, and the pieces that come into contact with the installation section 12 are joined by welding or the like to provide side reinforcing pieces 17.

[0023] The wall material mounting fixture 30 is fixed to the male end of the new drywall material 1A, and as shown in Figure 1(b), has a base portion 31, a folded portion 32, and a second engagement portion 33. The base plate 31 is a rectangular flat plate and is fixed to the back side (the indoor side during construction) of the fixing piece 1B of the novel drywall material 1A with a fixing device 3 such as a rivet. The base plate 31 may have holes 23 for the fixing device 3.

[0024] The folded portion 32 is formed by folding back one side of the base portion 31 to form a folded portion 32 spaced apart from the base portion 31. It is desirable that this folded portion 32 be approximately parallel to the base portion 31. The male end of the new drywall material 1A, where the fixing piece 1B is located, is inserted into this folded portion 32, and the wall material fixture 30 is positioned so that the folded portion 32 is on the front side (outdoor side) of the new drywall material 1A and the base portion 31 is on the back side (indoor side) of the new drywall material 1A, and the base portion 31 of the wall material fixture 30 is fixed to the fixing piece 1B portion of the new drywall material 1A with a fixing device 3 such as a rivet. The new drywall material 1A can be inserted all the way into this folded portion 32 to fix the wall material fixture 30 to the new drywall material 1A. When the wall material fixture 30 is fixed to the new drywall material 1A in this manner, the folded portion 32 allows easy and consistent positioning from the male end of the new drywall material 1A.

[0025] The second engagement portion 33 is formed on the surface of the base portion 31 opposite the folded portion 32. The second engagement portion 33 is formed continuously from one end of the base portion 31 to the other end in a direction parallel to one side of the base portion 31 where the folded portion 32 is located. The second engagement portion 33 has two opposing, spaced-apart erected portions 34 and an engagement claw 21 at the tip of each erected portion 34. By forming these two erected portions 34 at a distance from each other, when the wall material fixture 30 is fixed to the indoor surface of the fixing piece 1B of the new drywall material 1A with a fixing device 3 such as a rivet, the protruding fixing device 3 can be contained between the two erected portions 34. The second engagement portion 33 engages with the first engagement portion 14 of the base material fixture 10, and the engagement claw 21 of the second engagement portion 33 engages with the engagement claw 20 of the first engagement portion 14 of the base material fixture 10.

[0026] This is just one example of a drywall material 1 repair fixture P consisting of a base material fixture 10 and a wall material fixture 30. As another example of the base material fixture 10, a bending guide portion 13 may be provided as shown in Figures 6(a) and (b). [Explanation of symbols]
