The locking piece 10 is provided corresponding to the position of the locking portion 11 in the direction perpendicular to the inserting direction of the engaging tool 4 so as to engage with the locking portion 11 provided on the fixture 5. There is. The locking portions 11 are arranged side by side in two rows along the inserting direction, and two locking pieces 10 are provided corresponding to the positions of the locking portions 11. The locking piece 10 may be provided so as to correspond to the position of the locking portion 11 so that it can be engaged with the locking portion 11, and when the locking portions 11 are arranged in three or more rows, The number of the locking pieces 10 can be three or more. Alternatively, one wide locking piece 10 may be provided to engage with the locking portions 11 in a plurality of rows.

Further, the connecting portion 8 is provided with a swing suppressing piece 22 that is formed so as to obliquely project from the connecting portion 8 toward the indoor side and the upper side. The rocking|swiveling suppression piece 22 is formed so that the front-end may contact|abut to the fixing plate 17, and by this, the engagement tool 4 reduces swinging (rattle) toward the fixing plate 17. .. That is, although the engagement tool 4 moves in the direction in which the engagement tool 4 moves closer to and away from the fixed plate 17, the engagement tool 4 is inserted into the fixture 5 so as to move in the front-back direction within a range in which the rocking suppressing piece 22 elastically deforms. ..

The fixture 5 is fixed to the wall base 2 and engages with the engagement device 4, and is made of metal. As shown in FIGS. 1C and 1D, the guide portion 9 is provided along each of both ends 18 of the rectangular plate-shaped fixed plate 17. The fixing plate 17 is formed with an opening 19 for inserting a fixing tool 38 such as a nail or a screw to fix the fixing tool 17 to the wall base 2. In addition, each guide portion 9 faces both end portions 18 of the fixed plate 17, an extending piece 20 that extends from both side edges of the both end portions 18 to the outdoor side, and faces both end portions 18 from the tip of the extending piece 20. And the guide pieces 21 provided as described above, each of which is formed in a U shape in a plan view. In each guide portion 9, the distance between both end portions 18 of the fixed plate 17 and the guide piece 21 is larger than the thickness of the connecting portion 8 of the engagement tool 4, and the extension piece 20 of each guide portion 9 is provided. The length between them is substantially the same as or slightly smaller than the length between both side edges of the connecting portion 8 of the engagement tool 4.

The fixed plate 17 is provided with a locking portion 11 for engaging with the engagement tool 4 by partially cutting and raising the fixed plate 17. For example, the locking portion 11 is on the outdoor side and the lower side. It is formed so as to project obliquely to the side. Further, the locking portions 11 are arranged side by side in two rows along the inserting direction of the connecting portion 8, and the respective locking portions 11 are arranged in a zigzag manner in the inserting direction of the connecting portion 8. That is, the locking portions 11 of one row and the locking portions 11 of the other row are arranged without overlapping in the lateral direction (direction perpendicular to the insertion direction), and are arranged in a zigzag shape in the insertion direction as a whole. doing. More specifically, the locking portions 11 in each row are arranged at equal pitches, and the locking portions 11 in one row and the locking portions 11 in the other row are half-spaced in the insertion direction. They are arranged with a pitch difference. By thus arranging the locking portions 11 in a staggered manner, the locking portions 11 in one row and the locking portions 11 in the other row do not line up in the lateral direction, and stress is applied to the fixing plate 17. Can be reduced and the rigidity of the fixing plate 17 can be increased. Further, when the engagement tool 4 is inserted into the fixing tool 5, one of the two locking pieces 10 is sequentially and alternately engaged and engaged with the engagement portion 11 which is deviated by a half pitch. The insertion position of the tool 4 can be finely adjusted. Although the example in which the locking portions 11 are arranged in two rows is shown, the arrangement is not limited to this, and the locking portions 11 may be arranged in three or more rows.

In addition, a line marking portion 46 is formed in a portion of the fixing plate 17 into which the engagement tool 4 is inserted and the rocking suppressing piece 22 contacts. The line marking portion 46 is provided by roughening the surface of the fixed plate 17, and is formed by cutting the surface of the fixed plate 17 into a plurality of straight lines in a direction perpendicular to the insertion direction. By thus forming the line marking portion 46, when the rocking suppressing piece 22 comes into contact, the tip of the rocking suppressing piece 22 is caught by the line marking portion 46, and the rocking suppressing piece 22 is fixed to the fixing plate 17. It is possible to reduce sliding on the top, and to support the engagement tool 4 with the fixing plate 17 to reduce swinging of the engagement tool 4 (backlash).

Then, as shown in FIGS. 1F and 2A, both ends 16 of the connecting portion 8 of the engaging tool 4 are inserted into the guide portions 9 provided at both ends 18 of the fixing tool 5 from above the fixing tool 5, and By engaging the locking piece 10 of the fitting 4 and the locking portion 11 of the fixing tool 5, the engaging tool 4 and the fixing tool 5 can be engaged as shown in FIG. 1F. At this time, since the locking piece 10 of the engagement tool 4 is formed so as to project upward and the locking portion 11 of the fixing tool 5 is formed so as to project downward, the engagement tool 4 is formed by engaging the both. The locking piece 10 and the locking portion 11 are locked so that they can be moved only in the inserting direction (downward) with respect to the fixture 5. Therefore, it is possible to prevent the engagement tool 4 from moving upward with respect to the fixing tool 5 and prevent the engagement between the hook portion 7 and the outer wall member 3 from coming off easily. And the fixing member 5 are firmly engaged with each other, and the engaging member 4 moves in the direction opposite to the inserting direction to prevent the engagement of the both members from being unintentionally released, thereby reliably supporting the outer wall member 3. It can be attached.

Further, in the outer wall material mounting tool 1 of the present embodiment, the displacement of the hook portion 7 in the front-rear direction with respect to the connecting portion 8 connected to the fixing tool 5 is restricted by the fixing tool 5. That is, each of the left and right end portions 16 of the connecting portion 8 is fitted into the guide portion 9 of the fixture 5 to regulate the displacement of the hook portion 7 in the front-rear direction. That is, since both ends 16 of the connecting portion 8 can contact the both ends 18 of the fixed plate 17 and the guide piece 21, the longitudinal displacement of the hook portion 7 is restricted by the fixture 5. Therefore, even if a negative pressure is applied to the outer wall member 3 hooked on the outer wall member attaching tool 1, the hooking portion 7 and the connecting portion 8 are unlikely to be deformed. That is, even if the negative pressure applied to the outer wall member 3 is applied to the hook portion 7, the displacement of the hook portion 7 in the front-rear direction is restricted by the fixture 5 and is reduced. Therefore, even if a negative pressure is applied to the outer wall member 3, the hook portion 7 is less likely to be displaced with respect to the connecting portion 8, and stress is less likely to be generated in the hook portion 7 and the connecting portion 8 and deformation is less likely to occur.

FIG. 2B shows a structure in which the outer wall material 3 is attached using the outer wall material attachment 1 of the present embodiment. In the illustrated example, the hooking piece 15 of the hooking portion 7 provided on the engaging tool 4 is hooked in the groove 6 formed in the cut surface that appears when the upper portion of the outer wall material 3 is cut. By hooking the engagement tool 4 in the groove 6 in this manner, the outer wall member 3 and the engagement tool 4 can be hooked and attached to the wall base 2. Further, the center hooking piece 15a is formed to be inclined toward the hooking connecting piece 13 more than the end hooking piece 15b, and the hooking tip piece 45 is tilted to the outdoor side at the tip of each hooking piece 15. Since the groove 6 is formed, even if an error occurs in the position of the groove 6 formed in the outer wall member 3 in the thickness direction, and the groove 6 and the hooking piece 15 are misaligned, the central hooking piece 15a is formed. Can contact the cut surface of the groove 6 to absorb this thickness error, and reliably insert the hooking piece 15 into the groove 6 and hook it to support the outer wall member 3.

Further, since the tip of the rocking suppressing piece 22 abuts the fixed plate 17 to support the fixed plate 17, the engaging tool 4 and the fixing tool 5 are easily fixed firmly, and the strength of the outer wall material mounting tool 1 is increased. Therefore, the mounting structure of the outer wall member 3 having high strength can be formed.

As described above, normally, the engagement piece 10 of the engagement tool 4 and the engagement portion 11 of the fixing tool 5 are disengaged by once pulling out the connecting portion 8 of the engagement tool 4 that has been inserted. Although the outer wall member 3 is formed so that it cannot be engaged, when the outer wall member 3 is replaced, the engagement can be released by using an appropriate jig.

By the way, the engaging tool 4 and the fixing tool 5 in the illustrated example can be obtained by processing a metal plate. That is, the engaging tool 4 and the fixing tool 5 can be formed by appropriately subjecting the metal plate to processing such as cutting, drilling, and bending, which requires welding and complicated processing. In addition, the outer wall material mounting tool 1 can be easily manufactured by simple processing.

Then, by mounting the outer wall material 3 on the wall foundation 2 of the building using the outer wall material mounting tool 1 formed as described above, a mounting structure for the outer wall material 3 as shown in FIG. 9 can be formed. .. Although the case where the opening 55 is a window will be described below, the outer wall member 3 can be similarly attached to the opening 55 other than the window.

Hereinafter, first, the attachment of the outer wall member 3 on the lower side of the opening 55 will be described. In attaching the outer wall material 3, first, the outer wall material 3 is processed.

As shown in FIG. 4, first, an extra portion of the upper portion of the outer wall material 3 is cut off to form the outer wall material 3 into a desired shape (a concave shape in the figure). Although FIG. 4 shows the case of the wide opening 55 that straddles three wall foundations 2 (vertical furring strips), the case of the opening 55 that spans one wall foundation 2 (vertical furring strips) is shown. May be

Next, as shown in FIG. 5A and FIG. 5B, the groove 6 (upper groove 6a) is formed in the cut surface that appears by cutting the upper portion of the outer wall material 3. At this time, the groove 6 is provided in a portion of the outer wall member 3 which is overlapped with the wall foundation 2 (a portion indicated by A in FIG. 4). The groove 6 can be easily formed at a construction site by using an appropriate processing tool. The groove 6 may be formed over the entire length of the cut surface of the outer wall material 3, or may be formed only at a predetermined position where the outer wall material fitting 1 is attached as shown in the drawing. The shape of the groove 6 may be a substantially rectangular cross section in a front view, or may be a semicircular cross section in a front view as illustrated.

As the outer wall material 3, it is possible to use an outer wall material 3a having a plurality of hollow holes 60 therein as shown in FIG. 5C or a solid outer wall material 3b as shown in FIG. 5E. After forming, the groove 6 can be formed as shown in FIGS. 5D and 5F. Here, when the outer wall member 3a having a plurality of hollow holes 60 provided therein is used, the groove 6 can be formed, for example, with reference to the indoor side surface of the hollow hole 60 as shown in FIG. 5D. .. The broken line shown in FIG. 5B indicates a guideline for the depth of the groove 6.

To attach the outer wall member 3 processed as described above, first insert both end portions 16 of the connecting portion 8 of the engaging member 4 into the guide portions 9 of the fixing member 5 from above to attach the engaging member 4 to the fixing member 5. Hook and connect. However, at this stage, the connecting portion 8 of the engagement tool 4 is not completely inserted into the fixing tool 5. This is because the outer wall member 3 can be easily engaged with the engagement tool 4 later. Then, the fixtures 5 such as nails and screws are used to fix the fixtures 5 to the wall base 2, as shown in FIG. 6A. Alternatively, the fixing tool 5 may be first fixed to the wall base 2, and then the fixing tool 5 and the engaging tool 4 may be engaged with each other. 6 to 9, the opening frame 37 and the outer wall material 3 are shown by being cut so that the state of attachment can be confirmed, and a part of the outer wall material fitting tool 1 hidden by the outer wall material 3 is shown by a broken line as appropriate. ing. In the figure, 53 is a waterproof tape.

Then, while lifting the outer wall material 3, by hooking the hooking piece 15 of the hooking portion 7 of the engaging tool 4 into the groove 6 formed in the cut surface of the outer wall material 3, the outer wall material 3 and the engaging tool 4 are Hook.

Next, as shown in FIGS. 7A and 7B, first, the outer wall member 3 is pushed down (arrow in the figure). At this time, the lower portion of the outer wall member 3 is structured to be supported by a normal fastener (not shown). After that, as shown in FIGS. 8A and 8B, the engaging member 4 is pushed down to firmly insert the hooking piece 15 of the hooking portion 7 into the groove 6 to fix the outer wall member 3 and to connect the engaging tool 4. The part 8 is completely inserted into the fixture 5 from above, and the engaging tool 4 and the fixture 5 are hooked and connected (arrows in the figure). Alternatively, both the outer wall member 3 and the engaging member 4 are pushed down at the same time so that the lower portion of the outer wall member 3 is placed on the fastener (not shown) and the hooking piece 15 of the hooking portion 7 of the engaging member 4 is grooved. The outer wall member 3 may be fixed by firmly inserting it into the outer wall member 3.

At this time, the insertion positions of the engagement tool 4 can be finely adjusted by the zigzag-shaped locking portions 11, so that the engagement tool 4 can be easily and firmly hooked on the outer wall material 3, and the outer wall material 3 can be easily hooked. The workability of attaching the material 3 is improved. Further, since the swinging restraining piece 22 reduces the swinging movement of the hooking portion 7 of the engagement tool 4 toward the indoor side, the hooking piece 15 of the engagement tool 4 can be easily and surely fitted into the groove of the outer wall member 3. 6 and the workability of attaching the outer wall member 3 can be improved. Further, since the rocking suppressing piece 22 of the attached engaging tool 4 is in contact with the fixing plate 17, the strength of the outer wall material mounting tool 1 in the indoor and outdoor directions can be improved, and an outer wall structure having high strength can be obtained. Can be formed.

Finally, as shown in FIGS. 9A and 9B, after the backup material 36 is attached, the sealing material 35 is used to fill the gap between the outer wall material 3 and the opening frame 37 to form the outer wall material attachment structure. The area remaining under the opening frame 37 can be completely covered.

In the attachment method described above, the engaging tool 4 is slightly inserted in advance into the fixing tool 5, the outer wall member 3 is arranged, and then the engaging tool 4 is completely inserted and fixed. The method of attaching the material 3 is not limited to this. For example, in a state where the engaging tool 4 and the fixing tool 5 are separated, after hooking the hooking piece 15 of the engaging tool 4 into the groove 6 of the outer wall material 3, the outer wall material 3 is placed under the opening 55. The outer wall member 3 may be attached by placing it on the side and then placing the supported portion of the outer wall member 3 on the fastener and inserting the engaging member 4 into the fixing member 5.

The outer wall member receiver 43 is formed by connecting the supporting portion 61 and the fixing portion 62. The fixing portion 62 includes a fixing piece 42 fixed to the wall base 2 on the upper side of the opening frame 37, a downward inclination piece 49 provided by inclining downward from the lower end of the fixing piece 42 to the outdoor side, and the downward inclination piece. A rear contact piece 50 that is provided so as to hang down from the lower end of the rear wall 49 and that contacts the rear surface of the outer wall member 3; and a support rear surface piece 64 that extends downward from the lower end of the rear contact piece 50. There is. The fixing piece 42 is formed with a fixing hole 52 for inserting a fixing tool 38 such as a nail or a screw to fix the fixing piece 38 to the wall base 2 on the upper side of the opening frame 37.

The support portion 61 is horizontally provided by being connected to the lower end of the support back surface piece 64, and a bottom surface contact piece 51 that comes into contact with the bottom surface of the outer wall member 3, and an upward projection from the tip of the bottom surface contact piece 51. The support piece 41 provided is provided with a support tip piece 65 that extends from the tip of the support piece 41 in an inclined manner toward the outdoor side.

In the outer wall member receiver 43, the lower portions of the supporting portion 61 and the fixing portion 62 are formed in a rectangular shape in a front view, but the lateral dimension of the supporting portion 61 and the lateral dimension of the lower portion of the fixing portion 62. Are the same as. That is, the horizontal dimension of the bottom contact piece 51 of the support portion 61 is the same as the horizontal dimension of the support back piece 64 in the lower portion of the fixed portion 62. That is, in this embodiment, the outer wall material receiver 43 does not have a structure corresponding to the constricted portion of Patent Document 1. The outer wall material receiver 43 can be formed by pressing a metal plate or the like, whereby the outer wall material receiver 43 having no step between the lower portion of the fixed portion 62 and the support portion 61 can be easily formed. can do.

The support portion 61 is continuously formed from one end to the other end in the left-right direction. That is, the support portion 61 is not divided into a plurality of parts in the left-right direction, and is not formed of a plurality of pieces as in Patent Document 1. Therefore, even if a negative pressure applied to the outer wall member 3 is applied to the support portion 61, the force generated by the negative pressure is easily dispersed throughout the support portion 61, and it is possible to prevent deformation.

As described above, the fixing piece 52 of the fixing portion 62 is formed with the fixing hole 52 penetrating in the thickness direction, but the ribs 80 are formed on both sides of the fixing hole 52 in the left-right direction. The rib 80 is formed so as to project from the surface of the fixed piece 42. Further, the rib 80 is formed from the fixed piece 42 to the descending inclined piece 49.

Further, a rib 81 is further formed outside the rib 80 in the left-right direction. That is, the ribs 81 are formed closer to the left and right ends of the fixed portion 62 than the ribs 80. The rib 81 is formed from the descending inclined piece 49 to the back contact piece 50, and is formed so as to project from the back surface of the descending inclined piece 49 and the back contact piece 50.

In this way, the fixing portion 62 is reinforced by both the ribs 80 and 81 to reduce deformation. That is, the load applied to the outer wall material 3 reaches the fixing portion 62 through the support portion 61 and reaches the peripheral portion of the fixing hole 52 fixed by the fixing tool 38, but the ribs 80 and 81 are formed on the left and right sides of the fixing hole 52. Because of the existence and reinforcement, the deformation of the fixing portion 62 due to the negative pressure can be suppressed. That is, when fixing a fixing tool such as a screw to the fixing hole 52, it is possible to suppress the deformation of the fixing portion 62 around the fixing hole 52, and it is difficult for the outer wall member 3 to be deformed due to the negative pressure. Further, when these outer ribs 81 are provided from the fixed piece 42 to the downward inclined piece 49, it is possible to suppress the bending portions of the fixed piece 42 and the downward inclined piece 49 from being deformed.

Further, ribs 82 are formed on the outer surface of the support portion 61. A pair of the ribs 82 are formed side by side in the left-right direction, and are formed so as to project to the lower surface of the bottom surface contact piece 51 (the outer surface (back surface) of the support portion 61). Further, the rib 82 is formed so as to extend from the lower portion of the supporting back surface piece 64 to the bottom surface contact piece 51. The ribs 82 can reinforce the support portion 61 and suppress the deformation of the support portion 61 due to the negative pressure applied to the outer wall member 3. Further, since the rib 82 is provided on the outer surface (back surface) of the support portion 61, it is possible to prevent the outer wall member 3 supported by the support portion 61 from interfering with the rib 82.

Next, attachment of the outer wall member 3 on the upper side of the opening 55 will be described.

When the outer wall material 3 is attached to the upper side of the opening 55, as shown in FIG. 11, first, as in the case of the lower side of the opening 55 (in the case of FIG. 4), the lower part of the outer wall material 3 is firstly attached. Excessive portions are cut off to form the outer wall material 3 into a desired shape. Next, as in the case of FIG. 5, as shown in FIGS. 12A to 12F, the groove 6 (lower groove 6b) is formed in the cut surface that appears by cutting the lower portion of the outer wall material 3.

Then, as shown in FIGS. 13A and 13B, the fixing pieces 42 of the outer wall material receiving tool 43 are fixed to the wall foundation 2 by using fixing tools 38 such as nails and screws. Thereafter, as shown in FIGS. 14A and 14B, by hooking the support piece 41 of the outer wall material receiving tool 43 into the groove 6 formed in the cut surface of the outer wall material 3, the outer wall material 3 and the outer wall material receiving tool 43 are separated from each other. hook. Finally, as shown in FIGS. 15A and 15B, the gap between the outer wall material 3 and the opening frame 37 is filled with the sealing material 35 and the backup material 36. In this way, the area remaining on the upper side of the opening frame 37 can be completely covered.

By mounting the outer wall material 3 on the upper side and the lower side of the opening 55 by the method as described above, the outer wall material mounting structure as shown in FIGS. 16 and 17 can be formed. 16 and 17 show an example in which a backup material 36 having a substantially rectangular cross section is used. As the backup material 36, a material formed of an elastic body can be appropriately used. The wall base 2 may be a horizontal furring strip.

As described above, according to the present embodiment, the outer wall material 3 can be attached to the wall base material 2 without directly driving or screwing the fasteners 38 such as nails and screws into the outer wall material 3, and a plurality of outer wall materials can be attached. In the case of attaching 3 to the wall base 2 adjacent to each other, even if a region smaller than the size of the normal outer wall material 3 remains above and below the opening 55, it is cut into a desired size. By attaching the outer wall material 3 to the wall foundation 2, the area can be covered and eliminated.
