It projects substantially vertically from the tip of the piece 64 downward (on the opposite side to the fixed piece 26). Here, the protruding dimension of the locked piece 64 from the fixed piece 26 is formed to be equal to or slightly larger than the protruding dimension of the locking plate 13 of the fixing member 4 from the substrate 10. Further, the dimension between the upper and lower opposed pieces 64 and 64 is formed to be equal to or slightly larger than the height dimension of the locking plate 13.

  As the new exterior material 2, a known outer wall material or roof material can be used. For example, a metal siding material or the like formed into a concave-convex section by bending a metal plate or the like can be used. In addition, as the new exterior material 2, a heat insulating panel (sandwich panel) formed by filling a heat insulating material between two metal shells can be used.

  And when repairing the existing wall of a building using the repairing part A, the new base material 12, and the new exterior material 2 of the present invention, it is performed as follows.

  First, the fixing member 3 of the repair part A is attached to the outdoor surface of the existing exterior material 1 constituting the existing wall of the building. Here, the existing exterior material 1 of the corrugated slate plate is attached to a structural material 62 such as a beam of a building with an existing fixture 5 such as a hook bolt, and the fixing member 3 is attached using the existing fixture 5. That is, as shown in FIG. 6, the existing exterior material 1 is formed by alternately connecting up and down ridges 1 a and valleys 1 b, and the existing fixture hooked on the structural material 62 of the building. The existing exterior material 1 is attached to the structural material of a building by providing the fastener 9 at the front-end | tip of the existing fixing tool 5 which 5 penetrates the mountain part 1a and protrudes on the outdoor surface of the mountain part 1a. The fastener 9 includes a packing 9c, a washer 9a, and a nut 9b. The packing 9c and the washer 9a are attached in this order to the tip of the existing fixture 5, and then a nut 9b is further attached to the tip of the existing fixture 5. To conclude.

  Then, as shown in FIG. 7, the fixing member 3 is attached to the outdoor surface of the existing exterior member 1 by inserting and locking the existing fixing tool 5 in the mounting hole 6. When inserting the existing fixture 5 into the mounting hole 6, the fixing member 3 is brought close to the existing fixture 5 from above, and the packing 9 c or the washer 9 a of the fastener 9 fastened to the existing fixture 5 and the existing exterior material 1 The mounting hole 6 is inserted into the existing fixture 5 from the lower end opening between the mountain portion 1a. When the mounting hole 6 is thus inserted into the existing fixture 5, the width dimension (diameter) of the packing 9 c and the washer 9 a of the fastener 9 is larger than the width dimension of the mounting hole 6. A certain locking plate portion 7b is sandwiched and locked between the packing 9c or the washer 9a and the existing exterior material 1, and thereby the fixing member 3 is locked and attached to the existing fixing tool 5. Can do. In addition, when inserting the attachment hole 6 into the existing fixture 5, the fixing member 3 may be hit from the upper side with a hammer or the like. However, it is preferable to use the attachment tool B described later because damage to the existing exterior member 1 can be prevented. .

  Here, since the lower end opening edge of the mounting hole 6, that is, the surface of the lower end of the locking plate portion 7 b is formed as an inclined surface 7 c, the locking plate portion 7 b is used as the packing 9 c or the washer 9 a and the existing exterior material 1. It is easy to insert between. In addition, the fixing member 3 is formed in a substantially square shape when viewed from the front (outdoor side) in a state where it is attached to the outdoor surface of the existing exterior material 1, and the existing fixture 5 is located at substantially the center thereof. become. Therefore, the new base material 12 to be described later can be attached long in the horizontal direction (horizontal direction) or can be attached long in the vertical direction (vertical direction). Even after the fixing member 3 is attached to the existing fixture 5, the nut 9b of the fastener 9 can be seen from the outdoor side. Therefore, for example, when it is difficult to insert the locking plate portion 7b which is the opening edge portion of the mounting hole 6 between the packing 9c or the washer 9a of the fastener 9 and the peak portion 1a of the existing exterior material 1, the nut 9b is loosened. The locking plate portion 7b is later inserted between the packing 9c or the washer 9a of the fastener 9 and the peak portion 1a of the existing exterior material 1, and thereafter, the nut 9b can be tightened. Further, even when the nut 9b is loosened before the fixing member 3 is attached under conditions such as aging of the building, the nut 9b after the fixing member 3 is attached to the existing fixture 5 can be tightened. Therefore, even after the fixing member 3 is attached, a stable attachment state can be confirmed, and the maintenance of attachment strength can be easily performed. Moreover, since the base board 7 which contacts the existing exterior material 1 of the fixing member 3 is a shape which substantially follows the R shape (convex curve shape) of the outdoor surface of the peak part 1a, the peak part 1a of the existing exterior material 1 is used. The fixing member 3 can be smoothly attached to the existing fixture 5 without being shaved by the base plate 7, and dust of harmful substances (for example, asbestos) contained in the existing exterior material 1 is hardly generated. Further, the leg portions 8, 8 on both sides of the fixing member 3 are arranged in the valley portions 1 b, 1 b located on both sides of the mountain portion 1 a to which the fixing member 3 is attached. 8d is arrange | positioned in the state which does not contact the outdoor surface of the trough part 1b. And only when a certain positive pressure is applied to the new exterior (force to push the new exterior toward the existing exterior 1), the fixing member 3 is deformed and the leg piece 8d comes into contact with the outdoor surface of the valley 1b, It can withstand positive pressure. Thus, in the normal state, the leg piece 8d of the fixing member 3 does not contact the outdoor surface of the existing exterior member 1, and therefore, when the fixing member 3 is attached to the existing fixture 5, the existing exterior member is used by the leg piece 8d. 1 can be mounted without shaving, and dust of harmful substances is less likely to be generated.

  In this way, by attaching the fixing member 3 to each of the plurality of existing fixtures 5, 5... Projecting from the outdoor surface of the existing exterior material 1, the plurality of fixing members 3 are vertically and horizontally mounted on the outdoor surface of the existing exterior material 1. It arranges in. Here, the existing fixture 5 is usually positioned at the upper end of the mounting hole 6, but by moving each fixing member 3 up and down within the length range of the mounting hole 6 with respect to the existing fixture 5, The plurality of fixing members 3 arranged in the horizontal direction are aligned at the same height.

  Next, as shown in FIG. 8, the height adjusting member 4 is disposed on the outdoor side of each fixing member 3 attached to the outdoor surface of the existing exterior material 1. Here, the height adjusting member 4 is not attached to the fixing member 3 or the type of the height adjusting member 4 attached to each fixing member 3 is selected according to the unevenness of the existing exterior material 1. That is, when two types of height adjusting members 4a and 4b having different heights are used, the fixing member 3 disposed at a relatively indoor position on the outdoor surface of the existing exterior member 1 is high. One height adjusting member 4a is provided. In addition, the height adjusting member 4 is not provided on the fixing member 3 disposed at a position relatively on the outdoor side of the outdoor surface of the existing exterior material 1. Further, the lower height adjustment member 4b is provided on the fixing member 3 disposed in the middle of the location on the relatively indoor side and the location on the relatively outdoor side of the outdoor surface of the existing exterior material 1. Is provided. In this way, the modified part A of the present invention can be adjusted to three levels of height.

  When a plate-like wall material such as a corrugated sheet slate plate is used as the existing exterior material 1, unevenness of the outdoor surface of the existing exterior material 1 is caused by the overlap of the adjacent existing exterior materials 1 and 1. That is, when the existing exterior of a building is formed by arranging a plurality of existing exterior materials 1, 1 ... vertically and horizontally, the ends of the existing exterior materials 1, 1 that are adjacent in the vertical and horizontal directions overlap (overlapping). The position is indicated by Δ in FIG. 9). Accordingly, the dimensions from the existing wall base (trunk frame or the like) to the outdoor surface of the existing exterior material 1 are partially different, and the existing exterior material of the repair part A is used in the construction method using the existing fixture 5 as in the present invention. It is necessary to partially adjust the protrusion dimension from the outdoor surface of 1. For example, in the case of an existing exterior as shown in FIG. 9, the substantially central portion (position indicated by L in FIG. 9) of each existing exterior material 1 is in contact with the existing base and is located on the most indoor side. Further, portions corresponding to the upper end, the lower end, and the side end of each of the existing exterior materials 1 at positions just above, directly below, and directly next to the substantially central portion (position L) of each of the above existing exterior materials 1 (FIG. 9). (Positions indicated by M1 and M2) are portions where the ends of the adjacent existing exterior materials 1 and 1 overlap each other, and the thickness of the existing exterior material 1 (for example, 8 mm) compared to the position of the above L It is a location located outside. Further, the portion directly above and below the position of M1 and the portion directly next to the position of M2 (the position indicated by H in FIG. 9) are portions where the ends of the adjacent existing exterior materials 1 and 1 are affected by overlapping. Compared with the position of L, it is a location located on the outdoor side by the thickness (for example, 16 mm) of the two existing exterior materials 1. Therefore, the fixing member 3 and the higher height adjustment member 4a are attached to the existing fixture 5 at the position L, and the fixing member 3 and the lower height are attached to the existing fixture 5 at the positions M1 and M2. The adjustment member 4b is attached, and only the fixing member 3 is attached to the existing fixture 5 at the position H.

  In disposing the height adjusting member 4 on the outdoor side of the fixing member 3, as shown in FIG. 1A, the height adjusting member 4 is brought closer to the fixing member 3 attached to the existing exterior material 1 from the outdoor side. The tip of the existing fixture 5 is inserted into the locking hole 14 of the height adjusting member 4. As shown in FIG. 1B, the tip of the existing fixture 5 penetrates the attachment hole 6 by inserting the existing fixture 5 into the attachment hole 6 of the fixing member 3 as described above. It is a part protruding to the outdoor side, and is a part protruding further to the outdoor side than the nut 9 b of the fastener 9 fastened to the existing fixture 5. When the tip of the existing fixture 5 is inserted into the locking hole 14 of the height adjusting member 4 in this way, the opening edge of the locking hole 14 is locked to the existing fixture 5, thereby The height adjusting member 4 can be held on the existing fixture 5.

  Here, the height adjusting member 4 is disposed so that the pair of locking plates 13 and 13 provided on the height adjusting member 4 face each other in the lateral direction (horizontal direction). Further, the rear end of the projecting piece 24 of the height adjusting member 4, the rear end of the projecting piece 23, and the rear surface of the substrate 10 are brought into contact with the surface of the mounting portion 8 b of the leg portion 8 of the fixing member 3 and the rotation preventing piece 25 is provided. It inserts between the leg parts 8 and 8 which the fixing member 3 opposes. Thereby, even if the height adjusting member 4 tries to rotate around the existing fixture 5, the side end portion of the rotation preventing piece 25 comes into contact with the surface of the inner wall portion 8 a of the leg portion 8 of the fixing member 3 to adjust the height. The rotation of the member 4 can be prevented. Further, the concave portion 21 of the height adjusting member 4 is positioned between the opposing leg portions 8 and 8 of the fixing member 3. Thus, by attaching the height adjusting member 4 to each fixing member 3 one by one, a plurality of repair parts A composed of the fixing member 3 and the height adjusting member 4 are arranged vertically and horizontally on the outdoor surface of the existing exterior material 1. It can be arranged.

  Next, as shown in FIG. 1C, a new base material 12 is supported by a plurality of repair parts A, A,. The base material 12 is bridged. Here, the new base material 12 is configured such that the support portion 16 is locked to the locking plate 13 of the height adjusting member 4 of each repaired part A. That is, the new base material 12 is brought close to the existing exterior material 1 from the outdoor side, the pair of locking plates 13 and 13 are inserted between the upper and lower locked pieces 64 and 64 of the support portion 16, and the upper locked By placing the piece 64 on the upper end surface of the locking plates 13 and 13, the new base material 12 can be locked to the locking plates 13 and 13. Further, the upper fixing piece 17 of the new base material 12 abuts on the surface (outdoor surface) of the upper coupling piece 11 of the height adjusting member 4 and the lower fixing piece 17 of the new base material 12 is the height adjusting member. 4 is disposed in contact with the surface (outdoor surface) of the lower coupling piece 11. For the fixing member 3 to which the height adjusting member 4 is not attached, the fixing piece 17 of the new base material 12 is brought into contact with the outdoor surface of the attaching portion 8 b of the leg portion 8 of the fixing member 8. In this way, the new base material 12 can be disposed in a state of being temporarily fixed to the height adjusting member 4.

  Next, as shown in FIGS. 10 to 12, the temporarily fixed new base material 12 is fixed (mainly fixed) to the height adjusting member 4 and the fixing member 3. When the new base material 12 is fixed to the height adjusting member 4 and the fixing member 3, a new fixture 15 such as a screw is screwed into the fixing piece 17 of the new base material 12 in the temporarily fixed state from the outdoor side and driven. The new fixture 15 is passed through the fixing piece 17 and the coupling piece 11 and screwed into the attachment portion 8b of the leg portion 8 of the fixing member 3 to be driven. Thereby, the fixing piece 17 of the new base material 12, the coupling piece 11 of the height adjusting member 4, and the mounting portion 8b of the fixing member 3 can be connected by the new fixing tool 15, and the height of the new base material 12 is adjusted. It can be fixed (mainly fixed) to the member 4 and the fixing member 3. Here, the new fixture 15 is driven into the mounting portion 8b at the diagonal two corners or the four corners of the fixing member 3 with the existing fixture 5 interposed therebetween. As a result, the new fixtures 15 are arranged approximately evenly around the axis of the existing fixture 5, and the moment generated when the fixtures are not uniform can be minimized. Then, by suppressing the generation of moment, a load is applied in the vertical direction to the center of the existing fixture 5, so that the load on the existing exterior material 1 is reduced as compared with the case where the moment is not uniform. Even if a large load is applied to the wall surface, the existing exterior material 1 is difficult to break. Moreover, since the front-end | tip part of the existing fixing tool 5 is stored in the inner space of the support part 16 of the new base material 12, and it hides, the extra length of the existing fixing tool 5 can be absorbed using this, The length of the extra length of the existing fixture 5 is almost unrelated, and the troublesome cutting of the existing fixture 5 does not have to be performed.

  As described above, by temporarily repeating the temporary fixing and the main fixing of the new base material 12, a plurality of new base materials 12, 12... Can be arranged on the outdoor side of the existing exterior material 1. Here, in the horizontal direction (horizontal direction), a plurality of new base materials 12, 12,... Are arranged in a substantially straight line. In the longitudinal direction (vertical direction), a plurality of new base materials 12, 12,... Are arranged in parallel with each other.

  As described above, after a plurality of new base materials 12, 12... Are disposed on the outdoor side of the existing exterior material 1, a plurality of new exterior materials 2, 2 are attached to the outdoor side of the new base material 12. As shown in FIG. 13, the new exterior material 2 is arranged so as to be bridged over the adjacent new base materials 12, 12, and thereafter, a fixture 65 such as a drill screw is placed on the new base material from the outdoor side of the new exterior material 2. It can be attached so as to be screwed and driven into the fixing piece 26 of the support portion 16 of the material 12. Then, by arranging a plurality of new exterior materials 2, 2... Vertically and horizontally and arranging them on the outdoor side of the new base material 12, it is possible to cover the existing outer walls with the new exterior walls formed by the new exterior materials 2, 2.. Yes, the building can be renovated. In FIG. 13, a part of the new base material 12 and the new exterior material 2 are omitted.

  And in this invention, the kind of the height adjustment member 4 attached to the fixing member 3 is changed according to the surface of the existing exterior material 1, or the height adjustment member 4 is attached to the fixing member 3. By avoiding this, the unevenness of the existing exterior material 1 can be absorbed, and the new base material 12 does not float from the fixing member 3 or the height adjusting member 4. 12 can be securely fixed to the fixing member 3 to prevent insufficient strength of the new exterior. In addition, the projecting position of the new base material 12 from the outdoor surface of the existing exterior material 1 can be made constant, and the unevenness of the existing exterior material 1 does not appear on the surface (outdoor surface) of the new exterior material, thereby preventing appearance deterioration. Is something that can be done.

  In the repair part A provided with the plurality of height adjusting members 4 having different heights as described above, the unevenness generated on the outdoor surface of the existing exterior material 1 can be absorbed and reduced. That is, when the existing exterior material 1 is a corrugated slate plate such as a small wave slate plate, the existing exterior materials 1 and 1 that are adjacent in the horizontal direction and the vertical direction are constructed with their ends overlapped by several centimeters. . Accordingly, the position of the mountain portion 1a of the existing exterior material 1 in the indoor / outdoor direction is not constant in the vertical direction, and the overlapping portion of the adjacent existing exterior materials 1 and 1 is more protruded to the outdoor side. Therefore, the protrusion position to the outdoor side of the fixing member 3 attached to the outdoor surface of the mountain portion 1a varies, and accordingly, the height adjusting member 4, the new base material 12, and the new exterior material 2 on the outdoor side. As a result, the projecting position varies, and the surface of the new exterior becomes uneven.

  Therefore, a plurality of height adjusting members 4a and 4b having different heights are used properly as the height adjusting member 4 attached to the fixing member 3 as described above. For example, the height adjusting member 4 is not attached to the fixing member 3 located on the most outdoor side, and the height adjusting member 4a having the highest height is attached to the fixing member 3 located on the most indoor side. A height adjusting member 4b having a low height is attached to the fixing member 3 located at an intermediate position between the fixing member 3 to be fixed and the fixing member 3 positioned closest to the indoor side. Thereby, the position of the new base material 12 supported by the height adjusting member 4 becomes substantially constant in the indoor / outdoor direction, and the protruding position of the new exterior material 2 to the outdoor side becomes substantially constant. It is possible to prevent unevenness from occurring on the surface.

  In the present invention, the new base material 12 can be fixed to the fixing member 3 and the height adjustment member 4 by the new fixture 15 in a state where the new base material 12 is temporarily fixed by the height adjustment member 4. It is not necessary to fix the new base material 12 while supporting it at a predetermined position, and the construction becomes easy. Moreover, although the moment acting on the fixing member 3 is minimized as described above, an increase in the moment is also assumed due to a malfunction due to defective construction or the like, and in this case, the direction is shifted in the direction (upward) in which the fixing member 3 is inserted. There is a risk of returning upward from the existing fixture 5. Therefore, in the present invention, the movement of the height adjustment member 4 can be restricted by the existing fixture 5 by inserting the tip of the existing fixture 5 into the locking hole 14 of the height adjustment member 4 with almost no gap. The movement of the fixing member 3 can be restricted by the height adjusting member 4 by coupling the height adjusting member 4 and the fixing member 3, which are restricted in movement, with the new fixture 15. Inadvertent sliding movement along the longitudinal direction of the mounting hole 6 can be prevented. Moreover, since the latching hole 14 is provided in the bottom face of the recessed part 21 formed concavely shaped by press molding etc., the latching hole 14 can be located in the vicinity of the nut 9b of the existing fixture 5, For this reason, even if the front-end | tip part of the existing fixing tool 5 which protrudes on the outdoor side rather than the nut 9b is short, the latching hole 14 can be reliably inserted in the front-end | tip part of the existing fixing tool 5.

  In addition, the new exterior formed by the present invention needs to handle almost the same wind load acting on both positive pressure and negative pressure. For positive pressure (wind load that pushes the new exterior from the outdoor side), the base plate 7 that contacts the peak 1a of the new exterior member 1 of the fixing member 3 has an approximately R shape (convex shape), and the existing exterior material The load resistance is improved by an evenly distributed load in surface contact with the ridge 1a. Moreover, the leg part 8 arrange | positioned at the trough part 1b of the existing exterior material 1 is provided in the both sides of the fixing member 3, and it contacts with the trough part 1b only at the time of a positive pressure load, and it matches with the surface contact of the said base board 7 together. It bears positive pressure. In addition, the shape of the leg piece 8d that is in contact with the valley 1b of the leg 8 is made as long as an R shape, and the load on the existing exterior material 1 that has deteriorated by dispersing the positive pressure load is reduced. Prevention can be achieved. Further, with respect to negative pressure (wind load that pulls the new exterior to the outdoor side), the fixing member 3 is locked with the nut 9b and the washer 9a to obtain a load resistance.

  The modified part A of the present invention can also be used when the new base material 12 is disposed long in the vertical direction. In this case, the mounting method of the fixing member 3 and the height adjusting member 4 is the same as described above, but the mounting method of the new base material 12 is different from the above. That is, the new base material 12 is brought close to the existing exterior material 1 from the outdoor side, and the new base material 12 is inserted between the pair of locking plates 13 and 13 of the height adjusting member 4. Thereafter, as shown in FIG. 14, if necessary, the pair of locking plates 13 and 13 are tilted in the direction of approaching each other to narrow the interval so that the pair of locking plates 13 and 13 can form the new base material 12. Is sandwiched from both sides, and the new base material 12 is temporarily fixed by the height adjusting member 4. Thus, in order to make it easy to bend the pair of locking plates 13 and 13 by tilting them toward each other, a notch 27 is provided at the base of the locking plate 13. In addition, when the temporary fixing of the new base material 12 is unnecessary, it is not necessary to bend the locking plate 13. Thereafter, as shown in FIGS. 15 to 18, the fixing piece 17 of the new base material 12, the coupling piece 11 of the height adjusting member 4, and the mounting portion 8 b of the fixing member 3 are connected by the new fixing tool 15 in the same manner as described above. Then, the new base material 12 is fixed to the height adjusting member 4 and the fixing member 3. Thereafter, as shown in FIG. 19, the new exterior material 2 is attached to the outdoor side of the new base material 12 in the same manner as described above, and the repair is performed. In FIG. 19, some of the new base material 12 and the new exterior material 2 are omitted.

  In the present invention, when attaching the fixing member 3 to the existing fixture 5, a dedicated attachment tool B can be used. As shown in FIG. 20, the attachment tool B is formed with an operation member 40 and a fulcrum member 41. The operation member 40 is formed by providing a rod-shaped pressing portion 42 at the front end of an operation member main body 50 having a substantially U-shaped cross section, and providing a rod-shaped gripping portion 51 on the rear end surface of the operation member main body 50. Both end portions of the pressing portion 42 protrude outward from the side end surface of the operation member main body 50. Further, the fulcrum member 41 has a piece-like locking portion 44 projecting obliquely upward at the lower end (front end) of the fulcrum member main body 52 having a substantially U-shaped cross section, and the upper end (rear end) of the fulcrum member main body 52 is provided. The shaft portion 45 is pivotally attached to the operation member main body 50. The shaft portion 45 is located between the pressing portion 42 and the gripping portion 51, and the axial direction (longitudinal direction) of the shaft portion 45 is substantially parallel to the longitudinal direction of the rod-shaped pressing portion 42 and the rod-shaped gripping portion. The direction is substantially perpendicular to the longitudinal direction of 51. Accordingly, the operation member 40 is formed to be rotatable up and down with respect to the support member 41 with the shaft portion 45 as the center.

  And when attaching the fixing member 3 to the existing fixing tool 5 using this attachment tool B, it carries out as follows. First, as shown in FIG. 21A, the fixing member 3 is brought close to the existing fixture 5 from above, and the packing 9c or the washer 9a of the fastener 9 fastened to the existing fixture 5 and the peak portion of the existing exterior material 1 The fixing member 3 is temporarily placed on the existing fixture 5 between the packing 9c or the washer 9a and the peak portion 1a of the existing exterior material 1 by applying the inclined surface 7c at the lower end of the fixing member 3 between the fixing member 3 and 1a. At this time, the lower end opening of the mounting hole 6 of the fixing member 3 is located immediately above the existing fixture 5. Next, as shown in FIG. 21 (b), the locking portion 44 of the fulcrum member 41 of the attachment tool B is placed under the existing fixture 5 on the packing 9 c or washer 9 a of the fastener 9 and the crest of the existing exterior material 1. By inserting it between the parts 1a, it locks to the washer 9a of the fastener 9 fastened to the existing fixture 5, and both ends of the pressing part 42 of the operating member 40 are both recessed 8e of the fixing member 3. Fit from above. Next, as shown in FIG. 22A, the pressing portion 42 is urged to move downward by lifting the gripping portion 51 and rotating the operation member 40 about the shaft portion 45. . Thereby, the fixing member 3 can be pushed down by the pressing portion 42, and as shown in FIG. 22B, the existing fixing tool 5 is inserted into the mounting hole 6 and the fixing member 3 is placed on the outdoor surface of the existing exterior material 1. Can be attached.

  And the attachment tool B of this invention can attach the fixing member 3 to the existing fixing tool 5 with small force using a lever principle, and can attach the fixing member 3 easily. Further, in the mounting tool B of the present invention, the locking tool 44 is lifted (outdoor side) by inserting the locking portion 44 between the packing 9c or the washer 9a of the fastener 9 and the peak portion 1a of the existing exterior material 1. And the pressing portion 42 of the operation member 40 can be linearly operated substantially parallel to the surface of the existing exterior member 1. Furthermore, even when there is no surplus length of the existing fixture 5 (portion protruding outward from the fastener 9), the locking portion 44 is connected to the packing 9 c or washer 9 a of the fastener 9 and the peak portion 1 a of the existing exterior material 1. The attachment tool B can be supported by being locked between.
