Description

The present invention relates to a gap adjustment spacer that is used when attaching building materials (plate-shaped building boards, exterior wall boards, exterior wall materials, exterior materials, etc.) to a wall surface such as lightweight aerated concrete (ALC: Autoclaved Lightweight Aerated Concrete) or concrete (RC: Reinforced Concrete) that constitutes the exterior wall of a building, when the wall surface is uneven (unevenness, steps, etc.), and in particular to a gap adjustment spacer that can be inserted all the way to the back without increasing the size of the thin plate-shaped main body for adjusting the gap, improving ease of insertion work and wasting as little material as possible during manufacturing, and a method for manufacturing the same.

Exterior walls are formed by attaching multiple exterior materials to the exterior side of the wall base in a row and column. When attaching the exterior materials to the wall base, multiple wall material fasteners are provided on the exterior side of the wall base, and the exterior materials are held by these wall material fasteners. However, with wall bases with large unevenness, such as mortar walls, the protruding positions of each wall material fastener from the exterior surface of the wall base vary, so there is a problem that the exterior materials cannot be held by the wall material fasteners, or even if they are held, steps are created between the exterior materials, compromising the smoothness of the exterior side of the exterior wall. To address this problem, finely cut pieces of plywood or the like are inserted between the wall base and the wall material fasteners depending on the size of the unevenness, but cutting the plywood each time is time-consuming, and if the plywood is inserted as is, it is difficult to work because the plywood will fall if it is not held down by hand each time.

One possible solution is to insert a spacer for adjusting unevenness between the wall base and the wall material fastener. JP 2009-161953 A (Patent Document 1) filed by the applicant of the present application discloses an unevenness adjustment spacer that can be easily manufactured and installed. This unevenness adjustment spacer is a spacer for adjusting unevenness on the surface of the wall base when a wall material fastener for holding an exterior material is fixed to the wall base with a fastener such as a screw, and is characterized in that it is formed with a slit that extends from the center of the bottom edge of the board to a position above the center of gravity of the board, and is formed so that the board can be freely inserted from above between the wall base and the wall material fastener while the fastener that fixes the wall material fastener to the wall base is inserted into the slit.

JP 2009-161953 A

The unevenness adjustment spacer disclosed in the above-mentioned Patent Document 1 has been well received, but the following points may be problematic. In this unevenness adjustment spacer, the fastener that fixes the wall material fastener to the wall base is inserted into the slit while the board is inserted from above between the wall base and the wall material fastener. However, because the board is rectangular in shape, it may be difficult to insert it from above or to insert it all the way. In this case, it is possible to make the board larger while keeping it rectangular, or to provide a protrusion that serves as a handle to be held by holding it with your fingertips, but there may be sites where construction is easy even if the board is not large or has no protrusion, and making it larger or providing a protrusion may result in wasted material during manufacturing.

The present invention was developed in consideration of the above-mentioned problems with the conventional technology, and its purpose is to improve the ease of insertion of a gap-adjusting spacer, which is used when attaching building materials (plate-shaped building boards, exterior wall panels, exterior wall materials, exterior materials, etc.) to the ALC, RC, etc. wall surfaces that make up the exterior walls of a building when there are irregularities on the wall surface (irregularities, steps, etc.), by allowing the thin plate-shaped main body for adjusting the gap to be inserted all the way to the back without increasing its size, and further to provide a gap-adjusting spacer and a method for manufacturing the same that waste as little material as possible during manufacturing.

In order to achieve the above object, a gap-adjusting spacer according to one aspect of the present invention employs the following technical measures.
In other words, a gap adjustment spacer according to one aspect of the present invention is a spacer for adjusting a gap, characterized in that it comprises a thin plate-shaped main body portion, an opening formed by cutting out a portion of the periphery of the main body portion, a slit portion extending from the opening through approximately the center of the main body portion toward another periphery opposite the periphery without reaching the other periphery, and a protrusion portion other than the opening that protrudes outward from the periphery of the main body portion.

Preferably, the body portion is provided with one or more cutouts, the total area of the cutouts being approximately equal to the area of the protrusions.
More preferably, the protrusion is arranged to protrude outward from the other peripheral edge which is on an extension of the slit portion and which the slit portion does not reach, the protrusion has a shape which is contained within the slit portion, and the area of the slit portion can be configured to be larger than the area of the protrusion.

More preferably, the shape of the main body portion is approximately rectangular, the slit portion has an opening on one side of the main body portion by cutting out a portion of the one side, and the protrusion portion is configured to be provided at the intersection of two other sides different from the one side.
More preferably, triangular cutouts are formed at the three intersections other than the intersections of the two other sides, and the total area of the three cutouts is configured to be approximately equal to the area of the protrusion.

In addition, a manufacturing method according to another aspect of the present invention is a manufacturing method for any of the gap adjustment spacers described above, which is a manufacturing method for punching out multiple gap adjustment spacers of the same shape from a single sheet of plate material, and the gap adjustment spacers have a thin plate-shaped main body, a slit portion with an opening at a part of the periphery of the main body, and a protrusion provided so as to protrude outward from the periphery of the main body other than the opening, and the main body may have one or more cutouts, and the manufacturing method is characterized in that multiple gap adjustment spacers of the same shape are punched out from a single sheet of plate material adjacent to each other in the same direction, and the protrusion in one gap adjustment spacer is formed by the cutout or slit portion of another gap adjustment spacer adjacent to the one gap adjustment spacer.

Preferably, the shape of the main body is substantially rectangular, the slit portion has an opening on one side of the main body portion by cutting out a part of the one side, the protrusion is provided at the intersection of two other sides different from the one side, triangular cutouts are formed at the other three intersections excluding the intersection of the two other sides, the total area of the three cutouts is substantially equal to the area of the protrusion, and the protrusion of one gap adjustment spacer can be configured to be formed by the triangular cutouts of the other three gap adjustment spacers adjacent to the protrusion of the one gap adjustment spacer.

According to the present invention, for example, when attaching building materials (plate-shaped building boards, exterior wall panels, exterior wall materials, exterior materials, etc.) to the surface of an ALC, RC, or other material that constitutes the exterior wall of a building, if the wall surface is uneven (unevenness, steps, etc.), the gap adjustment spacer can be inserted all the way to the back without increasing the size of the thin plate-shaped main body for adjusting the gap, improving the ease of insertion, and further providing a gap adjustment spacer and a manufacturing method thereof that minimizes waste of material during manufacturing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A gap-adjusting spacer and a method for manufacturing the same according to an embodiment of the present invention will now be described in detail with reference to the drawings.
In the following description, metal siding is used as the exterior material (building board 200) used for the exterior wall of a building, furring strips are used as wall material fasteners for holding the metal siding, and anchor bolts are used as fasteners for fixing the furring strips to the exterior wall, but the gap adjustment spacer according to the present invention is not limited to such metal siding, furring strips, and anchor bolts. In the following description, the gap adjustment spacer according to the present invention is used when attaching building materials (plate-shaped building boards, exterior wall boards, exterior wall materials, exterior materials, etc.) to an existing wall surface when remodeling an existing wall surface made of ALC, RC, etc. that constitutes the exterior wall of a building, but the gap adjustment spacer according to the present invention may also be used when attaching building materials (plate-shaped building boards, exterior wall boards, exterior wall materials, exterior materials, etc.) to a newly built wall surface instead of remodeling the wall surface. In other words, the gap adjustment spacer of the present invention is not limited to use with metal siding, furring strips, anchor bolts, during reconstruction (remodeling), or during new construction, but is included in the present invention as long as it is fastened with at least a fastening device (anchor bolt, nail, screw, bolt, etc.).

1A shows a partial elevational view of a remodeling structure in which a building board 200 is attached to the wall surface of an exterior wall 100 of a building using a mounting fixture 1000, FIG. 1B shows a side view of the building board 200, and FIG. 1C shows an enlarged view of FIG. 1B. As shown in FIG. 1, metal siding, which is an example of the building board 200, is a building material that constitutes the exterior wall used in a building, and its overall shape is a substantially rectangular shape (approximately rectangular shape) when viewed from the front, and if its longitudinal dimension L is 4000 (a relative value, not an absolute value), it has a shape with a short side (working width) H of 360 to 580 and a thickness t of 14 to 23, and for example, the absolute values are a longitudinal direction L of 4000 mm or L of 3030 mm, a short side H of 430 mm (working width 400 mm excluding the upper fitting portion 220 and the lower fitting portion 210), and a thickness t of 16 mm. In addition to having this shape, this exterior wall material has features such as a male-female connection structure (upper mating portion 220 on the male side and lower mating portion 210 on the female side) at the top and bottom ends that stabilize the connection structure when the longitudinal direction is aligned horizontally.

This fixture 1000 is for attaching a building board 200 to the wall surface of an exterior wall 100 made of ALC, which is an example of an exterior wall in a building. This fixture 1000 includes furring strips 1100 and auxiliary members 1200. The furring strips 1100 are long (for example, 3600 mm
The furring strips 1100 are fixed to the wall surface of the exterior wall 100 at regular intervals by fasteners (anchor bolts 130). When the furring strips 1100 are fixed to the wall surface of the exterior wall 100 by fasteners in this way, if the wall surface of the exterior wall 100 is uneven (concave and convex), the gap adjustment spacer according to the present invention is preferably used, and even if the wall surface of the exterior wall 100 is uneven (concave and convex), the protruding position of the wall material fastener (here, the furring strip 1100) does not vary, so that the building board 200 (metal siding) can be securely held by the wall material fastener (the furring strip 1100), and no step is generated between the building boards 200 (metal siding), and the smoothness of the exterior side of the exterior wall is not impaired.

In this embodiment, the gap adjustment spacer of the present invention is used to adjust the gap on the surface of the wall base (to eliminate unevenness (unevenness, steps, etc.)) when the furring strips 1100, which serve as wall material fasteners for holding exterior materials (building boards 200 (metal siding)), are fixed to the wall base (wall surface) of the exterior wall 100 with fasteners (anchor bolts 130). However, the gap adjustment spacer of the present invention is not limited to use with such furring strips and anchor bolts (as described above).

1 shows a remodeling structure constructed in a "horizontal installation" manner in which the longitudinal direction of the mounting fixture 1000 is aligned with the vertical (sometimes referred to as "perpendicular") direction and the longitudinal direction of the metal siding, which is an example of the building board 200, is aligned with the horizontal direction. However, the gap adjustment spacer according to the present invention may also be applied to a remodeling structure constructed in a "vertical installation" manner in which the longitudinal direction of the mounting fixture 1000 is aligned with the horizontal direction and the longitudinal direction of the metal siding, which is an example of the building board 200, is aligned with the vertical direction, in which case the figure would be rotated 90 degrees from FIG. 1. That is, the gap adjustment spacer according to the present invention may be used to adjust unevenness (unevenness, steps, etc.) on the wall surface of the exterior wall 100 when the furring strips 1100 are fixed to the exterior wall 100 with anchor bolts 130 in a "horizontal installation" where the longitudinal direction of the building board 200 (metal siding) coincides with the horizontal direction, or when the furring strips 1100 are fixed to the exterior wall 100 with anchor bolts 130 in a "vertical installation" where the longitudinal direction of the building board 200 (metal siding) coincides with the vertical direction. The gap adjustment spacer of the present invention may be used to adjust unevenness (unevenness, steps, etc.) on the wall surface of the exterior wall 100 in this case, or may be used for other purposes. When a wall material fastener (here, furring strip 1100) for holding an exterior material (here, building board 200 (metal siding)) is fixed to the wall base (wall surface) of the exterior wall 100 with a fastener (here, anchor bolt 130), the gap adjustment spacer is used to adjust the gap on the surface of the wall base (to eliminate unevenness (unevenness, steps, etc.)).

As shown in Figure 1, in the case of "horizontal installation" in which the longitudinal direction of the building board 200 (metal siding) coincides with the horizontal direction, and the vertically installed furring strip 1100 is fixed to the exterior wall 100 with anchor bolts 130, the unevenness (unevenness, steps, etc.) in the wall base (wall surface) of the exterior wall 100 and the influence of the unevenness (unevenness, steps, etc.) will be explained with reference to Figure 2, which shows a case in which there is no unevenness (unevenness, steps, etc.) in the wall base (wall surface) of the exterior wall 100, and Figure 3, which shows a case in which the wall base (wall surface) of the exterior wall 100 has unevenness (unevenness, steps, etc.). Here, Fig. 2 and Fig. 3 are diagrams showing the case where the furring strip 1100 is fixed with the anchor bolt 130, which is a fastening device, with Fig. 2(A) and Fig. 3(A) being front views, Fig. 2(B) and Fig. 3(B) being elevation views, Fig. 2(C) and Fig. 3(C) being side views (during construction), and Fig. 2(D) as well as Fig. 3(D) and Fig. 3(E) being side views (construction completed).

As shown in FIG. 2, when there is no unevenness (unevenness, step, etc.) on the wall base (wall surface) of the exterior wall 100 (the surface position of the upper wall base (wall surface), the surface position of the middle wall base (wall surface), and the surface position of the lower wall base (wall surface) are the same surface position, as indicated by the open triangle mark), the furring strips 1100 can be fixed to the exterior wall 100 with anchor bolts 130 (without using the gap adjustment spacer according to the present invention) without unevenness (unevenness, step, etc.) on the wall base (wall surface) of the exterior wall 100. Therefore, the protruding position of the wall material fastener (here, the furring strips 1100) does not vary, so the building board 200 (metal siding) can be securely held by the wall material fastener (the furring strips 1100), and no step occurs between the building boards 200 (metal siding), which does not impair the smoothness of the exterior side of the exterior wall.

On the other hand, as shown in FIG. 3, if the wall base (wall surface) of the exterior wall 100 has unevenness (unevenness, steps, etc.) (the surface positions are shown as different between the open triangles indicating the surface positions of the upper and lower wall bases (wall surfaces) and the filled-in triangles indicating the surface position of the wall base (wall surface) in the middle between them), then even if the furring strips 1100 are fixed to the exterior wall 100 with anchor bolts 130 (unless the gap adjustment spacer of the present invention is used), the protruding position of the wall material fasteners (here, the furring strips 1100) will vary due to the unevenness (unevenness, steps, etc.) in the wall base (wall surface) of the exterior wall 100. As a result, the building board 200 (metal siding) cannot be securely held by the wall material fasteners (furring strips 1100), or steps will occur between the building boards 200 (metal siding), compromising the smoothness of the exterior side of the exterior wall. Furthermore, if you try to force the straightness of the furring strips 1100, gaps will form between the furring strips 1100 and the wall base of the exterior wall 100, making it impossible to securely fasten the furring strips 1100 (Figure 3 (E)).

The gap adjustment spacer according to the present invention is not limited to the reason for the occurrence of unevenness (unevenness, steps, etc.) on the wall base (wall surface) of the exterior wall 100 (for example, one reason for the occurrence is the joints between multiple panels installed on the exterior wall, but the reason for the occurrence is not important in the present invention), so in order to make it easy to understand, Figure 3 shows only that the unevenness DS occurs in the middle of the wall base of the exterior wall 100 (and in a state where the unevenness DS can be ideally seen).

Here, a basic construction method using the gap adjustment spacer according to the present invention when the wall base (wall surface) of the exterior wall 100 shown in FIG. 3 has an unevenness DS will be described first. That is, the gap adjustment spacer according to the present invention is used for the wall material fastener (furring strip 1100) attached to the recessed portion (unevenness DS) of the wall base (wall surface) of the exterior wall 100. The gap adjustment spacer according to the present invention has the following basic configuration. The gap adjustment spacer according to the present invention has a thin plate-shaped main body H, an opening KK in which a part of the periphery of the main body H is cut out, a slit portion S provided from the opening KK through approximately the center CC of the main body H in a direction toward another periphery facing the periphery without reaching the other periphery, and a protrusion T provided to protrude outward from the periphery of the main body H other than the opening KK.

The basic construction method using a gap adjustment spacer with such a configuration involves temporarily fastening the fastener (anchor bolt 130) by not completely driving it in and tightening it, and also temporarily fastening the wall material fastener (furring strip 1100). After this, the fastener (anchor bolt 130) in the temporarily fastened state is inserted through the opening KK at the lower end of the slit portion S of the gap adjustment spacer according to the present invention, while inserting the main body H into the gap (unevenness DS) between the temporarily fastened furring strip 1100 and the wall base (wall surface) of the exterior wall 100. Furthermore, when the fastener (anchor bolt 130) reaches the upper end of the slit portion S, the fastener (anchor bolt 130) is tightened to completely drive it into the wall base (wall surface) of the exterior wall 100.

This allows the wall material fastener (furring strip 1100) and the gap adjustment spacer to be fixed to the wall base (wall surface) of the exterior wall 100 with the fastener (anchor bolt 130), and the thickness of the gap adjustment spacer can absorb unevenness on the surface of the wall base (wall surface) of the exterior wall 100. In this way, by using the gap adjustment spacer of the present invention, even if there is unevenness DS on the wall base (wall surface) of the exterior wall 100, the unevenness DS is absorbed by the gap adjustment spacer of the present invention, and the protruding position of the wall material fastener (here, furring strip 1100) does not vary, so the building board 200 (metal siding) can be securely held to the wall material fastener (furring strip 1100), and no steps are created between the building boards 200 (metal siding), which does not impair the smoothness of the exterior side of the exterior wall.

In this way, when fixing a wall material fastener (furring strip 1100) for holding a building board 200 (metal siding) (either directly or indirectly) to the wall base (wall surface) of an exterior wall 100 with a fastener (anchor bolt 130), a gap adjustment spacer according to an embodiment of the present invention that is preferably used when unevenness DS occurs in the wall base (wall surface) of the exterior wall 100 will be described in detail below. More specifically, the gap adjustment spacer 10 according to the first embodiment and the gap adjustment spacer 15 according to its modified example and the manufacturing method of the gap adjustment spacer 15 will be described in detail with reference to Fig. 4 and Fig. 5, the gap adjustment spacer 20 according to the second embodiment and the gap adjustment spacer 25 according to its modified example and the manufacturing method of the gap adjustment spacer 25 will be described with reference to Fig. 6, the gap adjustment spacer 30 according to the third embodiment and the gap adjustment spacer 35 according to its modified example and the manufacturing method of the gap adjustment spacer 35 will be described with reference to Fig. 7, the gap adjustment spacer 40 according to the fourth embodiment and the gap adjustment spacer 45 according to its modified example and the manufacturing method of the gap adjustment spacer 45 will be described with reference to Fig. 8, and the gap adjustment spacer 50 according to the fifth embodiment and the gap adjustment spacer 55 according to its modified example and the manufacturing method of the gap adjustment spacer 55 will be described with reference to Fig. 9. Here, in the first to fifth embodiments, the same structures are given the same reference numerals. The explanations of those will overlap with the explanations of the embodiments described above, so they will not be repeated in the embodiments described later.

First Embodiment
The gap adjustment spacer 10 according to the first embodiment, the gap adjustment spacer 15 according to a modification thereof, and a method for manufacturing the gap adjustment spacer 15 will be described with reference to FIGS.
Gap adjustment spacers These gap adjustment spacers 10 and 15 are spacers used to adjust gaps (irregularities (bumps, steps, etc.)) on the surface of the wall base (wall surface) of the exterior wall 100 when fixing a wall material fastener (furring strip 1100) for holding the exterior material, the building board 200 (metal siding), to the wall base (wall surface) of the exterior wall 100 with a fastener (anchor bolt 130). 4(A) and 4(B), the gap adjustment spacer 10 and the gap adjustment spacer 15 are provided with a thin plate-like main body H, an opening KK formed by cutting out a part of the periphery 11 of the main body H, a slit portion S provided in a direction from the opening KK through approximately the center CC of the main body H toward the other periphery 12 opposed to the periphery 11 without reaching the other periphery 12, and a protrusion T provided so as to protrude outward from the periphery of the main body H (here, the intersection KT of the periphery 12 and the periphery 14) other than the opening KK. The shape of this protrusion T is a generally rectangular shape that is inclined obliquely.

Here, the gap adjustment spacer 15 shown in Figure 4 (B) has one or more cutout portions K provided in the main body portion H, and the total area of the cutout portions K (here, the total area of the three cutout portions K) is approximately equal to the area of the protrusion portion T.
In the gap adjustment spacer 10 shown in FIG. 4(A) and the gap adjustment spacer 15 shown in FIG. 4(B), the shape of the main body H is approximately rectangular, the slit portion S has an opening KK in the periphery 11, which is one side of the main body H, by cutting out a part of the periphery 11, and the protrusion T is provided at the intersection KT of two other sides different from the periphery 11, which is the one side (the periphery 12, which is the other side, and the periphery 14, which is yet another side).

Here, as shown in FIG. 4(C), the gap adjustment spacer 15 shown in FIG. 4(B) has triangular cutouts K formed at three intersections (i.e., the corner where the periphery 12 intersects with the periphery 13, which is one side constituting the approximately rectangle, the corner where the periphery 13 intersects with the periphery 11, which is one side, and the corner where the periphery 11 intersects with the periphery 14, which is one side, of the approximately rectangle, which are the three corners of the approximately rectangle excluding the intersection KT) excluding the intersection KT of the two other sides where the protrusion T is provided, and the total area of the three cutouts K is approximately equal to the area of the protrusion T. That is, as shown in FIG. 4(C), the area TS of the protruding portion T of the gap adjustment spacer 15A is approximately equal to the sum of the triangular area KS1 of the notch 15R1K of the gap adjustment spacer 15R1 adjacent to the gap adjustment spacer 15A on the upper side, the triangular area KS2 of the notch 15R2K of the gap adjustment spacer 15R2 adjacent to the gap adjustment spacer 15A on the diagonally upper side, and the triangular area KS3 of the notch 15R3K of the gap adjustment spacer 15R3 adjacent to the gap adjustment spacer 15A on the right side (TS ≒ KS1 + KS2 + KS3).

Here, the width of the slit portion S is W(1)<W(2), and after the anchor bolt 130 is inserted up to the upper end of the slit portion S, the gap adjustment spacer is less likely to come out of the anchor bolt 130, and the gap adjustment spacer can be prevented from falling off. The absolute value of the width of the slit portion S corresponds to the standard of the anchor bolt 130.

The main body H in these gap adjustment spacers 10 and 15 has a thin plate shape using, for example, resin materials such as foamed resin, polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), and metal materials such as stainless steel, aluminum, and iron. It is also preferable to form it into a substantially rectangular shape such as a square or rectangle. The size of the main body H is not particularly limited, but it is preferable to form it taking into account the size of the furring strip 1100, which is the wall material fastener. Although not limited, for example, when the size of the main body H is about 60 mm long x 48 mm wide, the thickness is about 2 mm. In addition, it is preferable to set the width of the slit portion S to W(1) = 12 mm and the width W(2) = 14 mm, with respect to 12 mm, which is the maximum thickness in the standard of the anchor bolt 130 corresponding to ALC. The thickness of the main body H can be varied, for example, to 2 mm, 5 mm, 10 mm, etc., and the combination and number of types of gap adjustment spacers used can be changed depending on the degree of unevenness (unevenness, step DS). The thickness of this gap adjustment spacer, including the main body H, is uniform, and the approximate center CC is the center of gravity (even when considering the slit S, protrusion T, and notch K).

Here, by adopting the above-mentioned materials (resin materials such as foamed resin, polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), etc., particularly triple-foamed polypropylene), the body H can be constructed by preparing gap adjustment spacers of various thicknesses and combining the number and thickness of the spacers. Since the unevenness (unevenness, steps, etc.) that actually occurs cannot always be made the same as the thickness of the gap adjustment spacer (no matter how gap adjustment spacers of different thicknesses are combined, it may not be possible to make the thickness the same as the unevenness (unevenness, steps, etc.) that actually occurs), it is preferable to use the above-mentioned flexible material in that the gap adjustment spacer is compressed and finely adjusted between the furring strip 1100 and the exterior wall 100 by tightening the anchor bolt 130.

Manufacturing Method of the Gap Adjustment Spacer 15 A manufacturing method of the gap adjustment spacer 15 will be described in detail with reference to FIG. 4(B) and FIG. 4(C).
The manufacturing method of the gap adjustment spacer 15 is a manufacturing method of punching out a plurality of gap adjustment spacers 15 of the same shape from a sheet of plate material, the gap adjustment spacer 15 has a thin plate-like main body H, a slit part S with an opening KK as a part of the periphery 11 of the main body H, and a protruding part T provided so as to protrude outward from the periphery of the main body H except for the opening KK, and one or more (here, three) cutout parts K are provided on the main body part, and the manufacturing method of the gap adjustment spacer 15 is to punch out a plurality of gap adjustment spacers 15 of the same shape adjacent to each other in the same direction from a sheet of plate material as shown in Fig. 4 (C). Even when adjacent, since the blade width of the punching blade is not 0, for example, when the size of the main body H is about 60 mm long x 48 mm wide, the spacers are punched out adjacent to each other with an interval of about 4 mm (about 8% of the short side dimension of the main body H).

In this case, as shown by the black and white arrows in FIG. 4(C), the protrusion T in one gap adjustment spacer 15A is formed by the cutout portions K of the other (three) gap adjustment spacers 15R1, 15R2 and 15R3 adjacent to the one gap adjustment spacer 15A.
Furthermore, in the gap adjustment spacer 15, the shape of the main body H is approximately rectangular, the slit portion S is provided with an opening KK in the periphery 11, which is one side of the main body H, by cutting out a part of the periphery 11, the protrusion T is provided at the intersection KT of two other sides (the periphery 12, which is the other side, and the periphery 14, which is the other side) different from the periphery 11, which is the one side, and triangular cutouts K are formed at the other three intersections (i.e., the three corners of the approximately rectangle excluding the intersection KT) excluding the intersection KT of the two other sides where the protrusion T is provided (here, the intersection KT of the periphery 12 and the periphery 14), and when the total area of the three cutouts K and the area of the protrusion T are approximately equal (the above-mentioned TS ≒ KS1 + KS2 + KS3), the manufacturing method of this gap adjustment spacer 15 is to punch out a plurality of gap adjustment spacers 15 of the same shape adjacent to each other in the same direction from a single plate material, as shown in FIG. 4(C). In this case, as shown by the black and white arrows in Figure 4 (C), the protrusion T in one gap adjustment spacer 15A is formed by the cut-out portions K of the other gap adjustment spacers 15R1, 15R2, and 15R3 adjacent to the one gap adjustment spacer 15A.

Installation method of the gap adjustment spacer 15 The installation method of the gap adjustment spacer 15 will be described in detail with reference to Fig. 5. The gap adjustment spacer 15 having the above-mentioned characteristic configuration will be described in addition to the above-mentioned basic installation method. Note that the states shown in Fig. 5(A), Fig. 5(B) and Fig. 5(C) are the states in the above-mentioned basic installation method in which the fasteners (anchor bolts 130) are not completely driven in and tightened, and the wall material fasteners (furring strips 1100) are also temporarily fastened. After that, as shown in Fig. 5 (A), the gap adjustment spacer 15 according to the modified embodiment is pinched between the fingers at the protruding portion T of the gap adjustment spacer 15, the gap adjustment spacer 15 is tilted so that the slit portion S is approximately inclined, and the fastener (anchor bolt 130) in the provisionally fastened state is inserted into the slit portion S from the opening KK at the lower end of the slit portion S (the gap adjustment spacer 15 is hooked on the anchor bolt 130), while the main body H is inserted into the gap (unevenness DS) between the provisionally fastened furring strip 1100 and the wall base (wall surface) of the exterior wall 100. At this time, the gap adjustment spacer 15 in the inclined state is gradually raised (while changing the inclined state to a vertical state) so that the slit portion S finally faces vertically (up and down direction) as shown in Fig. 5 (C), and the anchor bolt 130 is inserted from the lower side to the upper side of the slit portion S of the gap adjustment spacer 15. Then, when the fastener (anchor bolt 130) reaches the upper end of the slit portion S, the fastener (anchor bolt 130) is tightened so as to completely drive the fastener into the wall base (wall surface) of the exterior wall 100. At this time, as shown in Fig. 5(C), the slit portion S of the gap adjustment spacer 15 faces vertically (up and down).

In this case, before the fastening device (anchor bolt 130) is tightened, (1) the end of the slit section S is provided from the opening KK through approximately the center CC of the main body H (above approximately the center CC), and when the fastening device (anchor bolt 130) reaches the end of the slit section S, the thickness of this gap adjustment spacer is uniform and the center CC is the center of gravity, so it does not rotate, and it is possible to prevent the fastening device (anchor bolt 130) from falling off the slit section S (the gap adjustment spacer falling), and (2) since the width of the slit section S is W(1) < W(2), it is possible to prevent the fastening device (anchor bolt 130) from falling off the slit section S (the gap adjustment spacer falling), and by the time the fastening device (anchor bolt 130) is tightened and completely driven into the wall base (wall surface) of the exterior wall 100, the gap adjustment spacer does not rotate or fall, and unevenness can be suitably eliminated.

As described above, the gap adjustment spacer 10 and gap adjustment spacer 15 according to this embodiment are used when attaching building materials (plate-shaped building boards, exterior wall boards, exterior wall materials, exterior materials, etc.) to the ALC, RC, etc. wall surfaces that make up the exterior walls of a building, and when there are irregularities on the wall surface (irregularities, steps, etc.), the gap adjustment spacer can be inserted all the way to the back without increasing the size of the thin plate-shaped main body portion for adjusting the gap, improving the ease of insertion. The gap adjustment spacer 15 and the manufacturing method for the gap adjustment spacer 15 according to this embodiment make it possible to minimize the waste of material during manufacturing.

More specifically, in the gap adjustment spacer 15, triangular cutouts K are formed at three intersections (i.e., the corner at the intersection of the periphery 12 and the periphery 13, which is one side constituting the approximately rectangle, the corner at the intersection of the periphery 13 and the periphery 11, which is one side, and the corner at the intersection of the periphery 11 and the periphery 14, which is one side, of the approximately rectangle excluding the intersection KT) except for the intersection KT of the two other sides where the protrusion T is provided (here, the intersection KT of the periphery 12 and the periphery 14) (furthermore, the total area of the three cutouts K and the area of the protrusion T are approximately equal), but in the gap adjustment spacer 25, only one cutout K is provided other than the opening KK so as to recess inward from the periphery (the periphery 13 here) of the main body H. Also, the shape of this cutout K is approximately an isosceles triangle shape (with the base being the periphery 13), the same as the protrusion T.

The manufacturing method of this gap adjustment spacer 25 is a manufacturing method in which a plurality of gap adjustment spacers 25 of the same shape are punched out from a single sheet of plate material, and the gap adjustment spacer 25 has a thin plate-shaped main body portion H, a slit portion S with a part of the periphery 11 of the main body portion H as an opening KK, and a protrusion portion T provided so as to protrude outward from the periphery of the main body portion H other than the opening KK, and one or more (here, one) cut-out portions K are provided in the main body portion.The manufacturing method of this gap adjustment spacer 25 is a manufacturing method in which a plurality of gap adjustment spacers 25 of the same shape are punched out adjacent to each other in the same direction from a single sheet of plate material, as shown in Figure 6 (C).

In this case, as shown in FIG. 6C, the protruding portion T of one gap adjustment spacer 25 is formed by a cutout portion K of one gap adjustment spacer 25 adjacent to the one gap adjustment spacer 25.
As described above, the gap adjustment spacer 20 and the gap adjustment spacer 25 according to this embodiment can improve the ease of insertion work by allowing the gap adjustment spacer, which is used when attaching building materials (plate-shaped building boards, exterior wall boards, exterior wall materials, exterior materials, etc.) to the ALC, RC, etc. wall surfaces that make up the exterior walls of a building, to be inserted deep into the wall without increasing the size of the thin plate-shaped main body for adjusting the gap. The gap adjustment spacer 25 and the manufacturing method for the gap adjustment spacer 25 according to this embodiment can minimize the waste of material during manufacturing.

7, a gap adjustment spacer 30 according to a third embodiment, a gap adjustment spacer 35 according to a modification thereof, and a method for manufacturing the gap adjustment spacer 35 will be described. The same structures as those in the above-mentioned embodiment are denoted by the same reference numerals, and the description thereof overlaps with the description in the above-mentioned embodiment, so that it will not be repeated in this embodiment.

Unlike the corresponding gap adjustment spacers 10 and 15, the gap adjustment spacers 30 and 35 have a main body H with an upper part hollowed out in an arc shape rather than a substantially rectangular shape, and have the same slit portion S of the same shape at the same position of the main body H as the corresponding gap adjustment spacers 10 and 15. Therefore, the main body H including the slit portion S of the gap adjustment spacers 30 and 35 has an inverted U shape. The main body H of the gap adjustment spacers 30 and 35 is formed by the periphery 31 where the opening KK is provided, the left and right peripheries 33 and 34 connected to the periphery 31, and the semicircular arc-shaped periphery 32 (where the protrusion T is provided) connected to the left and right peripheries 33 and 34. In this embodiment, the periphery 32 is a semicircular arc, but this is not limited to this, and may be, for example, an R-shaped portion where the periphery 33 and periphery 34 are connected to the left and right periphery.

A gap adjustment spacer 30 corresponding to the gap adjustment spacer 10 has a projection T with a different position and shape.

Also, the shape of this protrusion T is a similar shape that is smaller than the slit portion S. However, it is not limited to a similar shape, and in the gap adjustment spacer 35, as long as the protrusion T has a shape that is included in the slit portion S (a shape in which the area of the slit portion S is larger than the area of the protrusion T), it is not limited to a similar shape.

The gap adjustment spacer 35 does not have any of the three notches K that the gap adjustment spacer 15 has, and the protrusion T of the gap adjustment spacer 35 is arranged to protrude outward (straight up) from another periphery (here, the top of the periphery 32) that is on the extension line of the slit portion S but does not reach the slit portion S, and the area of the slit portion S is larger than the area of the protrusion T, so that the protrusion T is contained within the slit portion S.

In the manufacturing method of this gap adjustment spacer 35, a plurality of gap adjustment spacers 35 of the same shape are punched out adjacent to each other in the same direction from a single sheet of plate material, as shown in Figure 7 (C).
In this case, as shown in FIG. 7C, the protrusion T of one gap adjustment spacer 35 is formed by the slit S of another gap adjustment spacer 35 adjacent to the one gap adjustment spacer 35 .

As described above, the gap adjustment spacer 30 and gap adjustment spacer 35 according to this embodiment can be used when attaching building materials (plate-shaped building boards, exterior wall boards, exterior wall materials, exterior materials, etc.) to the ALC, RC, etc. wall surfaces that make up the exterior walls of a building when there are irregularities on the wall surface (irregularities, steps, etc.), as the gap adjustment spacer can be inserted all the way to the back without increasing the size of the thin plate-shaped main body portion for adjusting the gap, improving ease of insertion.

The gap adjustment spacer 40 and the gap adjustment spacer 45 have a main body H that is not substantially rectangular but is entirely circular, unlike the corresponding gap adjustment spacer 10 and the gap adjustment spacer 15, and have the same shaped slit portion S at the same position of the main body H as the corresponding gap adjustment spacer 10 and the gap adjustment spacer 15. Therefore, the main body H including the slit portion S of the gap adjustment spacer 40 and the gap adjustment spacer 45 has a entirely circular shape. The main body H of the gap adjustment spacer 40 and the gap adjustment spacer 45 is formed by the periphery 41 where the opening KK is provided, the left and right peripheries 43 and 44 that are continuous with the periphery 41, and the arc-shaped periphery 42 (where the protruding portion T is provided) that is continuous with the left and right peripheries 43 and 44, and the periphery 41, periphery 42, periphery 43, and periphery 44 form the entire periphery by the entire circumference of the entire circle.

The gap adjustment spacer 40 corresponding to the gap adjustment spacer 10 has a projection T with a different position and shape.
More specifically, in the gap adjustment spacer 10, the protrusion T is provided so as to protrude outward from the periphery of the main body portion H (here, the intersection KT of the periphery 12 and the periphery 14) other than the opening KK, whereas in the gap adjustment spacer 40, the protrusion T is provided so as to protrude outward from the periphery of the approximately diagonal portion of the circumference of the upper part of the main body portion H (here, the periphery 42) other than the opening KK.

More specifically, in the gap adjustment spacer 15, the protrusion T is provided so as to protrude outward from the periphery of the main body H (here, the intersection point KT between the periphery 12 and the periphery 14) other than the opening KK, whereas in the gap adjustment spacer 45, the protrusion T is provided so as to protrude outward (straight up) from the periphery (here, the periphery 42) of the uppermost part of the circumference of the upper part of the main body H other than the opening KK. Also, the shape of this protrusion T is a similar shape that is smaller than the slit portion S. However, it is not limited to a similar shape, and in the gap adjustment spacer 45, as long as the protrusion T has a shape that is included in the slit portion S (a shape in which the area of the slit portion S is larger than the area of the protrusion T), it is not limited to a similar shape.

The gap adjustment spacer 45 does not have any of the three notches K that the gap adjustment spacer 15 has, and the protrusion T of the gap adjustment spacer 45 is arranged to protrude outward (straight up) from another periphery (here, the top of the periphery 42) that is on the extension line of the slit portion S but does not reach the slit portion S, and the area of the slit portion S is larger than the area of the protrusion T, so that the protrusion T is contained within the slit portion S.

A method for manufacturing the gap adjustment spacer 45 (only the differences from the gap adjustment spacer 15) will be described with reference to FIG. 8(B) and FIG. 8(C).
The manufacturing method of this gap adjustment spacer 45 is a manufacturing method in which a plurality of gap adjustment spacers 45 of the same shape are punched out from a single sheet of plate material, and the gap adjustment spacer 45 comprises a thin plate-shaped main body portion H, a slit portion S with an opening KK in part of the periphery 41 of the main body portion H, and a protrusion portion T provided so as to protrude outward (straight upward) from the top of the periphery 42 of the main body portion H other than the opening KK, and no cutout portion K is provided in the main body portion. In the manufacturing method of this gap adjustment spacer 45, a plurality of gap adjustment spacers 45 of the same shape are punched out adjacent to each other in the same direction from a single sheet of plate material, as shown in Figure 7 (C).
In this case, as shown in FIG. 8C, the protrusion T of one gap adjustment spacer 45 is formed by the slit S of another gap adjustment spacer 45 adjacent to the one gap adjustment spacer 45 .

As described above, the gap adjustment spacer 40 and gap adjustment spacer 45 according to this embodiment can be used when attaching building materials (plate-shaped building boards, exterior wall boards, exterior wall materials, exterior materials, etc.) to the ALC, RC, etc. wall surfaces that make up the exterior walls of a building when there are irregularities on the wall surface (irregularities, steps, etc.), as the gap adjustment spacer can be inserted all the way to the back without increasing the size of the thin plate-shaped main body portion for adjusting the gap, improving ease of insertion. The gap adjustment spacer 45 and the manufacturing method for the gap adjustment spacer 45 according to this embodiment can be used to minimize the waste of material during manufacturing.

In addition, by making the main body H a full circle, when multiple gap adjustment spacers 45 are stacked and used, the main body H will overlap neatly even if the position of the protrusion T is misaligned, allowing for more stable gap adjustment and making it easier to check that all gap adjustment spacers 45 are firmly inserted all the way.

Fifth embodiment
9, a gap adjustment spacer 50 according to the fifth embodiment, a gap adjustment spacer 55 according to a modification thereof, and a method for manufacturing the gap adjustment spacer 55 will be described. The same reference numerals are used for the same structures as those in the above-mentioned embodiment, and the description thereof overlaps with the description in the above-mentioned embodiment, so that it will not be repeated in this embodiment.

Unlike the corresponding gap adjustment spacers 10 and 15, the gap adjustment spacers 50 and 55 have a main body H that is not approximately rectangular but doughnut-shaped (a shape in which the outer periphery is formed around the entire circumference and the inner circle is punched out, like the gap adjustment spacers 40 and 45), and have a slit portion S of the same shape at the same position of the main body H as the corresponding gap adjustment spacers 10 and 15, and this slit portion S is connected to the inner circle of the main body H. Therefore, the main body H including the slit portion S of the gap adjustment spacers 50 and 55 has a slit portion S in a doughnut shape. In addition, the periphery of the main body H of the gap adjustment spacer 50 and the gap adjustment spacer 55 is the same as the periphery of the main body H of the gap adjustment spacer 40 and the gap adjustment spacer 45, so it is given the same reference number (periphery 41, periphery 42, periphery 43, and periphery 44 form the entire circumference of the entire circle).

A gap-adjusting spacer 50 corresponding to the gap-adjusting spacer 10 has a projection T with a different position and shape.
More specifically, in the gap adjustment spacer 10, the protrusion T is provided so as to protrude outward from the periphery of the main body portion H (here, the intersection KT of the periphery 12 and the periphery 14) other than the opening KK, whereas in the gap adjustment spacer 50, the protrusion T is provided so as to protrude outward from the periphery of the approximately diagonal portion of the circumference of the upper part of the main body portion H (here, the periphery 42) other than the opening KK.
A gap adjustment spacer 55 corresponding to the gap adjustment spacer 15 differs in the position and shape of the protrusion T, and in that the spacer does not include the notch K.

Also, the shape of the protrusion T is a similar shape that is smaller than the slit part S. Note that it is not limited to a similar shape, and in the gap adjustment spacer 55, it is not limited to a similar shape as long as the protrusion T has a shape that is included in the slit part S (a shape in which the area of the slit part S is larger than the area of the protrusion T).

Furthermore, the gap adjustment spacer 55 does not have any of the three cutout portions K that the gap adjustment spacer 15 has, and the protrusion portion T of the gap adjustment spacer 55 is arranged to protrude outward (straight up) from another periphery (here, the top part of the periphery 42) that is on the extension line of the slit portion S but does not reach the slit portion S, and the area of the slit portion S is larger than the area of the protrusion portion T, and the protrusion portion T is contained within the slit portion S.

In this case, as shown in FIG. 9C, the protrusion T of one gap adjustment spacer 55 is formed by the slit S of another gap adjustment spacer 55 adjacent to the one gap adjustment spacer 55 .

In addition, the gap adjustment spacer 50 and the gap adjustment spacer 55 according to this embodiment are provided with a donut-shaped main body H (a shape in which the outer periphery is formed around the entire circumference and the inner circle is punched out, like the gap adjustment spacer 40 and the gap adjustment spacer 45), and the slit portion S is connected to the inner circle of the main body H, but as shown in Figures 9(A) and 9(B), the width of the slit portion S satisfies W(1)<W(2), and after the anchor bolt 130 has been inserted up to the upper end of the slit portion S, it is possible to make it difficult for the gap adjustment spacer to come out of the anchor bolt 130, and it is possible to prevent the gap adjustment spacer from falling off.
That is, in this embodiment, the punched inner circle constitutes a part of the slit portion S.
