Description

[Technical Field]

[0001] The present invention relates to a fixture used when repairing damaged drywall materials that are the exterior walls of buildings. [Background technology]

[0002] In exterior walls constructed by sequentially connecting drywall materials such as metal siding with a male-female connection structure, if the drywall materials become damaged or dented, it becomes necessary to repair the drywall materials by replacing them. 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.

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

[0004] The examples and Figures 4 and 6 of Patent Document 1 show that a specific fixture is placed across the exterior surface of a base material, such as a furring strip (a column-shaped wall base), and its end is secured. However, when removing damaged drywall and using the empty space to secure a fixture to the base material from the exterior, the right or left half of the furring strip at the corner of the empty space is often hidden by the adjacent existing drywall. This necessitates a fixture that can be secured using one side of the base material (the side as viewed from the exterior). Furthermore, when securing a fixture to one side of the base material, because there is a furring strip on the left and right ends of the empty space, it becomes necessary to prepare fixtures for the right and left sides. Furthermore, when using the empty space to perform work from the exterior, problems arise when positioning and securing a fixture to the base material in a limited space, such as slippage while holding the fixture down or vibration caused by driving the fixture with an electric screwdriver. To provide a drywall repair fixture according to the present invention that can be fixed to only one side of a base material, can be fixed to either the left or right side of the base material, and can prevent displacement or rattle during fixing. [Means for solving the problem]

[0005] In order to solve these drawbacks, the present invention provides a fixture used when repairing drywall materials on an exterior wall where drywall materials having a male-female connection structure are adjacently connected, and the fixture is made up of two members: a base material fixture and a wall material fixture. The base material fixture has a rectangular flat base portion, an installation portion with one side of the bottom raised at a right angle, a bent guide portion extending from the tip of the installation portion and further extending at a right angle in the opposite direction to the installation portion side, and a first engagement portion erected from the installation portion at the center of the bottom on the installation portion side in a direction perpendicular to the bottom surface and the width of the bottom. The installation portion also has a plurality of protrusions on the surface opposite the bottom. The wall material fixture has a rectangular flat base portion, a folded portion extending one side of the base portion and folded back approximately parallel to the base portion with a gap therebetween, and a first engagement portion erected from the installation portion at the center of the base on the installation portion side in a direction perpendicular to the bottom surface and the width of the bottom. and a second engaging portion erected across the entire width of the base portion in the direction opposite the folded portion so as to be parallel to the side on which the folded portion is located; the base material mounting fixture is positioned by aligning it with a corner of the base material so that the bending guide portion contacts the front side of the base material when viewed from the outdoors and the installation portion contacts the side of the base material, and the protrusion of the installation portion is forced into the base material to fix the installation portion to the side of the base material; the wall material mounting fixture is fixed to the drywall material so that the base portion contacts the indoor side of the drywall material and the male end of the drywall material contacts the back of the folded portion, and the drywall material is mounted to the base material by engaging the first engaging portion of the base material mounting fixture fixed to the base material with the second engaging portion of the wall material mounting fixture fixed to the drywall material. [Effects of the Invention]

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

[0009] As shown in Figure 1, the repair fixture P for drywall material 1 of the present invention consists of two members, 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 a 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 makes up 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 or horizontal directions of the exterior wall surface.

[0011] An example of a drywall material 1 is metal siding as shown in Figure 3. Figure 3(a) is a side view of the metal siding, and Figure 3(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. The drywall material 1 may be any material that has a male-female connecting structure, and may be resin siding or a molded metal sheet.

[0012] A method of using the repair fixture P according to the present invention will now be described in detail. In an exterior wall where drywall materials 1 with male-female connection structures are connected next to each other, if damage such as scratches or dents occurs, it will be necessary to replace and repair the damaged drywall material 1. Taking horizontally laid drywall material 1 as an example, drywall material 1 (Fig. 3(a)) has a connection structure with a male type 1C at the top and a female type 1D at the bottom, and has a fixing piece 1B on the upper side of drywall material 1. The fixing piece 1B part of 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 male-female connected to the top, and this process is repeated in order to form the exterior wall.

[0013] The damaged drywall material 1 is removed from the exterior wall constructed in this way (Fig. 4(a)). The space created by the removal is used to secure the base material fixture 10 to the furring strip (base material 2) (Fig. 4(b)). New drywall material 1A is prepared, and a wall material fixture 30 is fixed to the inside (indoor side) of the fixing piece 1B at the top of the new drywall material 1A, and the new drywall material 1A is temporarily joined to the existing drywall material 1 that was below the removed drywall material 1. The top side of the 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 and temporarily joined to the new drywall material 1A in a V-shaped configuration when viewed from the side, and then the new drywall material 1A is pushed toward the indoor side as shown by the arrow (Fig. 4(c)). The new drywall material 1A is connected to the existing drywall material 1 above by a male-female connection, and the wall material fixture 30 fixed to the new drywall material 1A is engaged with the base material fixture 10 fixed to the furring strip (base material 2), thereby fixing the new drywall material 1A to the furring strip (base material 2) (Fig. 4(d)). This strong attachment and fixation by the repair fixture P prevents the new drywall material 1A from separating from the furring strip (base material 2), making it able to withstand wind pressure on the exterior wall.

[0014] Figure 5 shows the state in which the base material fixture 10 and wall material fixture 30 are used. Figure 5(a) shows the state in which the base material fixture 10 is fixed to the furring strip (base material 2), and the state in which the wall material fixture 30 is fixed to the new drywall material 1A. Figure 5(b) shows the state after the wall material fixture 30 and base material fixture 10 have been 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 fixture 10 is fixed to the furring strip (base material 2) and is shown in Figures 1(a), 2(a), and 2(b). Figure 1(a) is a perspective view, Figure 2(a) is a side view seen from direction A in Figure 1(a), and X is a partially enlarged view thereof. Figure 2(b) is a side view seen from direction B in Figure 1(a). As shown in these figures, the base material fixture 10 has a bottom portion 11, an installation portion 12, a bending guide portion 13, and a first engagement portion 14, and the installation portion 12 is provided with a protrusion 15.

[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. The installation section 12 may be provided with holes 22 for the fixing devices 3.

[0017] A plurality of protrusions 15 are provided by pressing or the like on the surface of the installation section 12 facing the bending guide section 13, and these protrusions 15 bite into the wooden furring strips to prevent misalignment. By forming a plurality of protrusions 15 as shown in Figure 2(b), a set position is stably maintained. When fixing the base material fixture 10 to the furring strip, these protrusions 15 prevent the fixing position from moving unintentionally. Note that Figure 2(a) shows an example of the shape of the protrusions 15.

[0018] The bending guide portion 13 extends from the tip edge of the raised installation portion 12, and then bends at a right angle to extend to the opposite side of the bottom portion 11. When viewed from the outdoors, the bending guide portion 13 is positioned on the front side of the furring strip, and the installation portion 12 is positioned on the side of the furring strip, and 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. 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.

[0019] The first engagement portion 14 has two raised portions 17 spaced apart from the approximate center of the bottom portion 11, and engagement claws 20 at the tip ends of the raised portions 17. The two raised portions 17 are continuous across the width and face each other parallel to one another. 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 18 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.

[0020] 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 fastening to a furring strip, the furring strip fixture 10 is fastened 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 fasten the furring strip fixture 10 to the side of the furring strip from the exterior side, the furring strip at the edge of the space may only be fastened to the right or left side of the furring strip. In this case, if the furring strip fixture 10 is flipped 180 degrees up and down, it can be fastened to either the left or right side of the furring strip. The furring strip fixture 10 is fastened to the furring strip at the top of the space through 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.

[0021] The bottom 11 may also be provided with side reinforcing pieces 16 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 16.

[0022] 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.

[0023] 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 makes it possible to easily and consistently position the new drywall material 1A relative to the male end portion thereof.

[0024] 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.

[0025] 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]
