Description

The present invention relates to a mounting unit such as a bracket mounted on a wall surface.

When mounting an article such as a dry cloth on a wall surface, for example, a mounting unit as described in Patent Document 1 below can be used. 8 and 9 show the mounting unit described in Patent Document 1 below, in which the mounting unit is a combination of the first member 2 having the first surface portion 1 and the second member 4 having the second surface portion 3. It is configured to include a mounting body 5, and an internal space 6 is formed between the first member 2 and the second member 4. More specifically, for example, the first member 2 includes a first surface portion 1 that comes into surface contact with the wall surface 7, and a first side portion 8 formed around the first surface portion 1, and the second member 4 Provided a plate-shaped second surface portion 3. Then, the second member 4 is arranged on the opposite side of the wall surface 7 with respect to the first member 2, and an internal space 6 corresponding to the thickness of the first side portion 8 is formed between the first surface portion 1 and the second surface portion 3. ..

A plate-shaped receiving portion 9 is arranged in the internal space 6, and a fastening hole 10 is opened in the center of the receiving portion 9. Then, the fastening shaft 13 of the fastening member 12 such as a bolt is attached to the mounting body 5 so as to penetrate the insertion holes 11 opened in the first surface portion 1 and the second surface portion 3, respectively, and the fastening hole 10 of the receiving portion 9. Insert into. The fastening shaft 13 penetrates the insertion hole 11 of the second surface portion 3, the fastening hole 10 of the receiving portion 9, the insertion hole 11 of the first surface portion 1, and the wall surface 7 in this order, and is tightened to the wall surface 7. The mounting body 5 is supported with respect to the wall surface 7 by sandwiching the mounting body 5 between the fastening head 14 of the fastening material 12 and the wall surface 7. A washer 15 is sandwiched between the wall surface 7 side of the fastening head 14.

At this time, the receiving portion 9 follows the fastening groove 16 spirally formed along the fastening shaft 13 of the fastening member 12, and as shown in FIG. 9, the fastening portion 9 rotates on the second surface portion 3 side due to the rotation of the fastening shaft 13 accompanying the tightening. The second surface portion 3 is sandwiched between the fastening head 14 and the washer 15 and the receiving portion 9. Then, the fastening member 12 is fastened to the wall surface 7 while supporting the second member 4 so as to sandwich the second surface portion 3 between the fastening head 14 and the receiving portion 9, and the first member 2 is fastened to the fastening member 12. It is pressed against the wall surface 7 via the second member 4 by the tightening force. In this way, the first surface portion 1 constituting the mounting body 5 is pressed against the wall surface 7 with as much uniform force as possible, and a good fixed state can be obtained.

Japanese Unexamined Patent Publication No. 2017-110335

However, in the case of the mounting unit as described above, there is a possibility that non-uniform mounting may occur due to deformation of the receiving portion 9 depending on the application. Since the receiving portion 9 is formed of, for example, an aluminum plate having a size of about 1 mm to several mm, for example, when the fastening material 12 is inserted in a direction slightly inclined with respect to the wall surface 7, it is strong as the fastening material 12 is tightened. When a force is applied, the surface formed by the receiving portion 9 may be distorted so as to be twisted. The twisting of the receiving portion 9 affects the holding of the second surface portion 3 between the receiving portion 9 and the fastening head 14 of the fastening member 12, and as a result, the first to the wall surface 7 via the second member 4. The pressing of the member 2 causes tilting and rattling, and the uniformity of the weight distribution with respect to the wall surface 7 of the first surface portion 1 is impaired.

In order to prevent the receiving portion 9 from being deformed, it is conceivable to increase the thickness of the receiving portion 9, for example. However, it is difficult to process a thick plate material as shown in the receiving portion 9 shown in FIGS. 8 and 9, which may significantly increase the manufacturing cost of the mounting unit. Further, there is a problem that a large amount of force is required when screwing the fastening member 12, and the workability of mounting is deteriorated. It is conceivable to form a pitch corresponding to the fastening groove 16 of the fastening shaft 13 on the inner circumference of the fastening hole 10, but it is technically technical to drill a hole with a pitch in a plate material having a thickness of about 9 for the receiving portion. It is difficult, and even if it is possible, the manufacturing cost will rise further.

In view of such circumstances, the present invention is intended to provide a wall mounting unit capable of ensuring good mounting on a wall surface with a simple configuration.

The present invention includes a mounting portion provided with a first surface portion that abuts on the wall surface and a second surface portion that is arranged on the opposite wall surface side of the first surface portion so as to form a gap between the first surface portion. And an insertion hole arranged in the gap and provided with a plurality of sandwiching surfaces, an insertion hole formed in the second surface portion, and a fastening hole formed in each sandwiching surface of the sandwiching member. And, it is fixed to the wall surface by a fastening material that penetrates the insertion hole formed in the first surface portion and is fastened to the wall surface. A wall mounting unit configured to mesh with a fastening groove formed in a fastening shaft in the fastening hole and to support the second surface portion between the fastening head of the fastening material, and the sandwiching member. However, by sandwiching the outer periphery of the plurality of sandwiching plates forming the sandwiching surface with a holding material made of a pair of halves, the sandwiching surfaces are bundled so as to overlap each other and be connected to each other. A holding groove for inserting the outer periphery of each of the sandwiching plates is formed on the inner surface of the split body, and the spacing between the sandwiching plates is maintained by the spacing between the holding grooves. It is characterized by .

In the wall mounting unit of the present invention, it is preferable that the first surface portion and the second surface portion are connected to each other by an edge portion at the top and bottom, and at least one of the left and right sides of the gap is open. It is preferable that a rib surrounding the fastening hole is formed so as to suppress deformation due to the load of the sandwiching plate.

According to the wall mounting unit of the present invention, it is possible to obtain an excellent effect that good mounting on the wall surface can be ensured with a simple configuration.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1 to 4 show an example of the form of the wall mounting unit according to the implementation of the present invention. The wall mounting unit 20 of this embodiment is, for example, as shown in FIG. 1, a bracket for fixing the base of a clothesline or the like to the wall surface 7, but is not limited to this, and various types are fixed to the wall surface 7. Goods can be assumed.

As shown in FIG. 1, the wall surface mounting unit 20 of this embodiment includes two upper and lower mounting portions 21, and each mounting portion 21 has a first surface portion 22 that comes into surface contact with the wall surface 7 as shown in FIG. The second surface portion 23 is provided at a position separated from the first surface portion 22 on the opposite wall surface 7 side. The first surface portion 22 and the second surface portion 23 are vertically connected by an edge portion 24 forming a surface along the horizontal direction, and are viewed from the side by the first surface portion 22, the second surface portion 23, and the edge portion 24. As shown in 3, it has an annular cross section and forms a gap 25 between the first surface portion 22 and the second surface portion 23.

The upper and lower parts of the gap 25 are closed by the edge portion 24, but the left and right sides are open, and this can be used as an insertion port 25a to access the inside of the gap 25. Then, as shown in FIGS. 1 to 3, the sandwiching member 26 is inserted from the insertion port 25a and arranged in the gap 25. Here, both the left and right sides of the gap 25 are opened to form the insertion port 25a, but the insertion port 25a may be formed only on either the left or right side.

As shown in FIG. 2, the sandwiching member 26 of this embodiment is configured by holding a plurality of (here, three) sandwiching plates 27 with each other by a holding material 28. Each sandwich plate 27 is a plate-shaped member made of a material having higher strength than aluminum, such as stainless steel, and has a fastening hole 27a in the center. The sandwich plate 27 has a square shape as a whole, and has a thickness of, for example, 0.1 mm or more and 1 mm or less. However, the thickness of the sandwiching plate 27 can be appropriately changed depending on the required strength, workability at the time of mounting, ease of manufacturing and processing, the relationship with the dimensions of the gap 25, and the like. That is, as the thickness of each sandwiching plate 27 increases, the fixing strength at the time of mounting increases, but on the other hand, the force required at the time of mounting work increases and the workability deteriorates, and the manufacturing and processing of the sandwiching plate 27 Costs will also increase. Further, if the thickness of one sandwiching plate 27 is increased, the thickness of the sandwiching member 26 is increased by that amount, and a large gap 25 is required, which leads to an increase in the size of the entire mounting portion 21. In carrying out the present invention, the thickness of the sandwiching plate 27 should be determined in consideration of these conditions.

A rib 27b is formed in the sandwiching plate 27 so as to surround the fastening hole 27a, so as to suppress deformation of the sandwiching plate 27 due to a load. Although the square rib 27b is shown here, the shape of the rib 27b is not limited to this, and may be, for example, a circular shape or another polygonal shape. Any shape may be adopted for the rib 27b as long as the deformation of the sandwich plate 27 can be appropriately suppressed.

The holding material 28 is a member that bundles the sandwiching plates 27 constituting the sandwiching member 26, and forms a regular square columnar tubular structure by combining two U-shaped half-split bodies 28a. Three holding grooves 28b are formed on the inner surface of each half-split body 28a, and the outer peripheral end portion of the sandwiching plate 27 can be inserted into each holding groove 28b. Then, one end of the sandwiching plate 27 is inserted into each holding groove 28b of one half-split body 28a, and the other end of each sandwiching plate 27 is inserted into each holding groove 28b of the other half-split body 28a. In this way, the two halves 28a are combined, and the sides of the sandwiching plates 27 are aligned with the holding grooves 28b on the inner circumference of the holding material 28, which forms a regular square columnar cylinder as a whole. The sandwiching plate 27 is bundled by the holding material 28. The outer periphery of each sandwiching plate 27 is held by the holding material 28 and bundled with each other, and at the same time, the spacing between the sandwiching plates 27 is maintained at the spacing between the holding grooves 28b. The half-split body 28a constituting the holding material 28 is formed of, for example, a resin, and the pair of half-split bodies 28a are combined with each other while inserting the sandwiching plate 27 into the holding groove 28b, and then one holding is performed by thermal adhesion. It is formed as a material 28. It should be noted that such a configuration is an example, and the holding material 28 and the half-split body 28a may be formed of another material.

The dimension of the sandwiching member 26 formed in this way is the minimum dimension in the direction orthogonal to the axial direction of the fastening hole 27a (that is, in the example shown here, the overall shape is square when viewed from the axial direction of the fastening hole 27a. The length of one side of the sandwiching member 26) is equal to or less than the vertical width of the gap 25, that is, the distance between the edges 24, and the maximum dimension (square-shaped sandwiching) in the direction orthogonal to the axial direction of the fastening hole 27a. The length of the diagonal line of the member 26) is set to be larger than the vertical width of the gap 25. That is, while the sandwiching member 26 can be accommodated in the gap 25, the shape and dimensions are such that the sandwiching member 26 cannot rotate about the axis of the fastening hole 27a in the gap 25. The shape of the sandwiching member 26 is not limited to the example shown here. Various shapes can be adopted for the sandwiching member 26 as long as the rotation can be restricted with respect to the gap 25.

Insertion holes 22a and 23a are opened in the centers of the first surface portion 22 and the second surface portion 23, respectively. The dimensions of the insertion holes 22a and 23a are set to be larger than the diameter of the fastening shaft 13 of the fastening material 12, and the fastening shaft 13 of the fastening material 12 is passed through the insertion holes 22a and 23a so that the fastening shaft 13 is connected to the first surface portion 22. It can be penetrated through the second surface portion 23. In the case of this embodiment , the insertion holes 22a and 23a are formed as long holes that are long on the left and right, so that the insertion position of the fastener 12 can be adjusted in the left and right direction.

Further, the diameter of the fastening hole 27a opened in each sandwiching plate 27 of the sandwiching member 26 is set so as to mesh with the fastening groove 16 formed in the fastening shaft 13 of the fastening member 12. In the example shown here, a spiral pitch is formed in the fastening shaft 13 of the fastening member 12 to form a fastening groove 16, and in the middle portion of the fastening shaft 13, the diameter at the bottom of the fastening groove 16 is the minimum diameter. , The diameter at the apex of the pitch is the maximum diameter. In this case, the diameter of the fastening hole 27a may be set to be equal to or larger than the diameter at the bottom of the fastening groove 16 of the fastening shaft 13 and less than the diameter at the apex of the pitch.

When mounting the wall surface mounting unit 20 of this embodiment on the wall surface 7, the wall surface mounting unit 20 is arranged at an appropriate position on the wall surface 7 so that the first surface portion 22 of the mounting portion 21 abuts on the wall surface 7 as shown in FIG. do. Then, the sandwiching member 26 is inserted from the insertion port 25a into the gap 25 between the first surface portion 22 and the second surface portion 23 of the mounting portion 21. Then, as shown in FIG. 3, the fastening shaft 13 of the fastening member 12 is inserted so as to penetrate the fastening hole 27a of the sandwiching member 26 from the insertion hole 23a of the second surface portion 23. At this time, the fastening shaft 13 is passed through the washer 15 in advance.

Here, in this embodiment , the first surface portion 22 and the second surface portion 23 are connected by the upper and lower edge portions 24 to form a gap 25, and the left and right sides are opened to form the insertion port 25a. Therefore, as compared with the above-mentioned conventional example (see FIGS. 8 and 9), the sandwiching member 26 (corresponding to the receiving portion 9) can be easily installed in the gap 25 (corresponding to the internal space 6). That is, in the case of the above-mentioned conventional example, the receiving portion 9 is arranged inside the first side portion 8 of the first member 2, and then the second member 4 is placed so as to cover the receiving portion 9 and the first side portion 8. The fastening member 12 is inserted while being arranged and supported by hand or the like so that the receiving portion 9 and the second member 4 do not fall off. However, in the case of the mounting portion 21 as in this embodiment , the fastening member 12 is inserted from the insertion port 25a. All that is required is to insert the sandwiching member 26 and insert the fastening member 12. Once the sandwiching member 26 is inserted into the gap 25, the sandwiching member 26 is supported by the lower edge portion 24, and is connected to the first surface portion 22 as well as the second surface portion 23 by the edge portion 24. It is not necessary to support the sandwiching member 26 and the second surface portion 23 so that they do not fall off when the fastening member 12 is inserted. It also has the effect of reducing the number of parts and reducing the management effort.

Next, the fastening head 14 of the fastening member 12 inserted into the insertion hole 23a is rotated, and the fastening member 12 is tightened with respect to the fastening hole 27a of the sandwiching member 26. Along with the tightening, the fastening shaft 13 advances to the wall surface 7 side, penetrates the fastening hole 27a, and reaches the insertion hole 22a of the first surface portion 22. Further, the wall surface 7 is pierced through the insertion hole 22a and tightened deeper than the wall surface 7.

At the time of tightening, each sandwiching plate 27 constituting the sandwiching member 26 meshes with the spiral fastening groove 16 formed in the fastening shaft 13 of the fastening member 12 in the fastening hole 27a. On the other hand, as described above, the sandwiching member 26 does not rotate in the gap 25. As a result, as the fastening shaft 13 rotates, each sandwiching plate 27 that meshes with the fastening groove 16 moves in the gap 25 toward the anti-wall surface 7 along the spiral surface of the fastening groove 16. Finally, as shown in FIG. 4, the tip end side of the fastening shaft 13 is buried inside the wall from the wall surface 7, and on the proximal end side of the fastening shaft 13, between the sandwiching member 26 and the fastening head 14. The two-sided portion 23 is sandwiched. The fastening shaft 13 supports the entire mounting portion 21 via the second surface portion 23 sandwiched between the sandwiching member 26 and the fastening head 14, and the mounting portion 21 presses the first surface portion 22 against the wall surface 7. Is fixed to the wall surface 7.

In this state, in the case of the present embodiment , the sandwiching member 26 is provided with a plurality of (three) sandwiching plates 27, and each of the sandwiching plates 27 is between the fastening head 14 of the fastening member 12. It works as a sandwiching surface for sandwiching the second surface portion 23. For this reason, the load applied to the wall surface 7 on the first surface portion 22 is maintained as evenly as possible.

During tightening, a strong force may be applied to the sandwiching member 26, and depending on conditions such as the angle of the fastening member 12 with respect to the wall surface 7, the sandwiching surface formed by the sandwiching plate 27 may be twisted. .. The twisting of the sandwiching surface may affect the holding of the second surface portion 23 with the fastening head 14. However, in the case of this embodiment , since the sandwiching member 26 is provided with a plurality of sandwiching plates 27 forming the sandwiching surface, even if some of the sandwiching plates 27 are twisted on the sandwiching surface. There is no large kinking on the sandwiching surface of another sandwiching plate 27, and it can be expected that the second surface portion 23 is properly held between the sandwiching plate 27 and the fastening head 14. In the above-mentioned conventional example (see FIGS. 8 and 9), the receiving portion 9 forming the sandwiching surface is formed as a single plate material. Therefore, if the single plate material is twisted, the twist is not the same. There was a risk that it would be directly linked to the non-uniform holding of the two-sided portion 3. In this embodiment , by using a plurality of sandwiching surfaces, the risk that kinking affects the holding of the second surface portion 23 is reduced.

Here, in this embodiment , the sandwiching plate 27 is formed thinner than the receiving portion 9 of the above-mentioned conventional example so as to provide a plurality of sandwiching surfaces and not to make the volume of the entire sandwiching member 26 too large. However, a material having a higher strength than aluminum is used as the material, and the ribs 27b are provided on the sandwiching plate 27 to secure the strength of each sandwiching plate 27 and prevent the sandwiching surface from being kinked. There is.

In tightening, since the fastening hole 27a of the sandwiching plate 27 meshes with the spiral fastening groove 16, each sandwiching plate 27 is deformed along the pitch forming the fastening groove 16 around the fastening hole 27a. (See FIG. 4), this deformation is local and does not affect the function of the sandwich plate 27 as the sandwiching surface. As a result of tightening, even if some deformation occurs in the meshing portion between the fastening groove 16 and the sandwiching plate 27, the sandwiching plate 27 which is the sandwiching surface is orthogonal to the fastening shaft 13 as a whole and the second surface portion. If the surface is parallel to the 23, it is sufficient to properly hold the second surface portion 23. Alternatively, although not shown, the periphery of the fastening hole 27a may be previously processed into a shape along the spiral surface of the pitch forming the fastening groove 16 so that deformation during tightening can be prevented as much as possible. good.

In the mounting work of the wall surface mounting unit 20 as described above, the holding material 28 bundles a plurality of sandwiching plates 27 so that they can be handled as one sandwiching member 26, thereby improving workability and between the sandwiching plates 27. It also serves to maintain a gap and assist each sandwiching plate 27 in properly meshing with the fastening groove 16 in the tightening process. In the fixed state shown in FIG. 4, each sandwiching plate 27 meshes with the fastening groove 16 adjacent to each other of the fastening shaft 13. one by one. In order to evenly transmit the tightening force of the fastening member 12 from the pitch of the fastening shaft 13 to each sandwiching plate 27 that meshes with the fastening groove 16, in this way, one round of the spiral fastening groove 16 is used. The optimum shape is that the sandwiching plates 27 are engaged with each other. Therefore, in the sandwiching member 26, if a holding groove 28b is formed in the holding material 28 and the sandwiching plate 27 is inserted into each holding groove 28b to secure a space between the sandwiching plates 27 in advance, tightening is performed. At this time, each sandwiching plate 27 meshes with the fastening groove 16 at an appropriate interval, and as a result, meshes with the fastening groove 16 adjacent to each other one by one. In this way, an appropriate fixed state can be easily realized.

As described above, in the wall mounting unit 20 of the present embodiment , between the first surface portion 22 that abuts on the wall surface 7 and the first surface portion 22 on the opposite wall surface 7 side of the first surface portion 22. The second surface portion 23 is provided with a mounting portion 21 having a second surface portion 23 arranged so as to form a gap 25, and a sandwiching member 26 arranged in the gap 25 and having a plurality of sandwiching surfaces 27. The insertion hole 23a is formed, the fastening hole 27a formed on each sandwiching surface 27 of the sandwiching member 26, and the insertion hole 22a formed on the first surface portion 22 are penetrated and fastened to the wall surface 7. It is fixed to the wall surface 7 by the fastening material 12, and at the time of fixing to the wall surface 7, the sandwiching surface 27 meshes with the fastening groove 16 formed in the fastening shaft 13 of the fastening material 12 in the fastening hole 27a and fastens the fastening material 12. The second surface portion 23 is supported between the head portion 14 and the head portion 14. By doing so, the second surface portion 23 is sandwiched between the sandwiching surface 27 and the fastening head 14 of the fastening member 12, so that the load applied to the wall surface 7 on the first surface portion 22 is maintained as evenly as possible. ing. At that time, by using a plurality of sandwiching surfaces 27, it is possible to reduce the risk that the kinks generated on the sandwiching surfaces 27 affect the holding of the second surface portion 23.

Further, in the present embodiment , the first surface portion 22 and the second surface portion 23 are connected to each other by the edge portion 24 at the top and bottom, and at least one of the left and right sides of the gap 25 is open. The sandwiching member 26 can be inserted into the gap 25 and held, and the workability in mounting the wall surface mounting unit 20 can be improved.

Further, since the present embodiment includes the holding material 28 for bundling the outer circumferences of the plurality of sandwiching plates 27 constituting the sandwiching surface 27, the plurality of sandwiching plates 27 may be used in the mounting work of the wall surface mounting unit 20. The workability can be further improved by bundling them so that they can be handled as one sandwiching member 26.

Further, in the present embodiment , since the holding groove 28b for inserting the outer periphery of each sandwiching plate 27 is formed on the inner peripheral surface of the holding material 28, the spacing between the sandwiching plates 27 is maintained and tightened. In the process, it assists each sandwich plate 27 to properly mesh with the fastening groove 16, and an appropriate fixing state can be easily realized.

Therefore, according to the above embodiment , good mounting on the wall surface can be ensured with a simple configuration.

5 and 6 show different reference examples (second and second reference examples ) of the present invention, respectively. Here, only the sandwiching member 26 is shown, and the configuration other than the sandwiching member 26 is the same as that of the above embodiment (see FIGS. 1 to 4), so that the illustration is omitted.

In the sandwiching member 26 (see FIG. 5) in the first reference example , an adhesive tape is used as the holding material 28 instead of the component (see FIG. 2) in which the holding groove 28b is formed as in the embodiment , and a plurality of sandwiching members are used. The sandwiching member 26 is formed by holding the side portion of the plate 27 with a holding material 28 which is an adhesive tape. Even in this way, it is sufficient to bundle the plurality of sandwiching plates 27 to improve the workability at the time of mounting, and the structure is as compared with the case where the holding material 28 having a specific shape is manufactured as in the above embodiment . Is simple and advantageous in terms of cost.

When the holding material 28 is used as an adhesive tape as in the first reference example , it is difficult to secure the space between the sandwiching plates 27 by the holding material 28, but for example, due to the thickness of the ribs 27b, the sandwiching plates 27 are connected to each other. It is possible to specify the interval between. Alternatively, if the thickness of each sandwiching plate 27 is set to be larger than half the width of the fastening groove 16 (see FIG. 4) and equal to or less than the width of the fastening groove 16, it will be formed in the fastening groove 16 around the circumference when tightening. On the other hand, it is possible to prevent two or more sandwiching plates 27 from engaging with each other.

Further, in the first reference example , the shape of the rib 27b formed on the sandwiching plate 27 is circular. As described above, the rib 27b can take various shapes as long as the twisting of the sandwiching surface can be suppressed.

The sandwiching member 26 (see FIG. 6) in the second reference example forms a plurality of sandwiching surfaces 27 that overlap each other by bending one plate material, and each sandwiching surface 27 is regarded as one component. They are connected to each other. By doing so, it is possible to hold the plurality of sandwiching surfaces 27 as one sandwiching member 26 without using the holding material 28 (see FIGS. 1 to 5), and the spacing between the sandwiching surfaces 27 is also appropriate. Can be kept in.

Further, in the second reference example , a notch is formed around the fastening hole 27a opened in each sandwiching surface 27 so that the fastener 12 is easily deformed along the fastening groove 16 at the time of tightening. .. By doing so, the deformation around the fastening hole 27a is unlikely to spread to other parts of the sandwiching surface 27, and the sandwiching surface 27 is less likely to be twisted. In addition, the force required for tightening can be reduced to improve workability. In addition, the fastening hole 27a can take various shapes as long as it can mesh with the fastening member 12 (see FIGS. 1 to 4).

As described above, in the second reference example , since the sandwiching member 26 is formed in a row so that the plurality of sandwiching surfaces 27 overlap each other, the plurality of sandwiching surfaces 27 may be one piece regardless of the holding material 28. It can be held as the sandwiching member 26, and the distance between the sandwiching surfaces 27 can be appropriately maintained.

Since other configurations and operational effects are the same as those in the above embodiment , the description thereof will be omitted, but the first and second reference examples can also ensure good mounting on the wall surface with a simple configuration.

FIG. 7 shows another example of possible configurations for the fastener 12 and the wall. In the above embodiment (FIGS. 1 to 4), the case where the fastening groove 16 is formed over the entire fastening shaft 13 as the fastening material 12 is illustrated, but as shown in FIG. 7, the tip that enters the back of the wall surface 7 is illustrated. The fastening groove 16 may be formed only in the portion and the base end portion that meshes with the sandwiching member 26. Further, the wall surface 7 may be the surface of a wall provided with a ventilation layer 7c between the outer wall material 7a and the base material 7b, for example, as shown here. In this case, the fastening material 12 is tightened to the base material 7b. Further, at this time, the outer wall material 7a may be provided with an insertion hole 7d.
