The number and interval of the first fixing holes 115H are appropriately set according to the structure of the structure 8 and the like.

  The portions of the first member 110 excluding the fixing portion 115, that is, the connecting portion 111, the support portion 114, and the top surface portion 113 constitute a substantially C-shaped cross-sectional portion. That is, the connecting part 111 constitutes a first wall part and connects the support part 114 and the fixing part 115. The support part 114 constitutes a second wall part. One end of the support portion 114 is connected to the connecting portion 111, and the other end of the support portion 114 is connected to the top surface portion 113. The top surface portion 113 constitutes a third wall portion and is disposed substantially parallel to the connecting portion 111.

  The connecting portion 111 is connected to the upper end edge of the fixed portion 115, is bent in the outdoor direction, extends so as to be separated from the structure 8, and extends in the left-right direction. The coupling portion 111 is provided with a plurality of through holes 114H penetrating in the vertical direction.

  The support portion 114 has a lower end edge connected to the distal end edge of the coupling portion 111, extends substantially in parallel with the fixed portion 115, that is, in the vertical and horizontal directions, and reaches the upper end edge.

  The top surface portion 113 is connected to the upper end edge of the support portion 114, bends in the indoor direction, extends so as to approach the structure 8, and extends in the left-right direction.

  A plurality of slits 118 are provided through the support portion 114 and extend long in the left-right direction. The number and interval of the slits 118 are set to a necessary and sufficient size so that hooks 129L and 129R described later can be inserted. That is, it is set slightly larger than the thickness of the plates constituting the hook portions 129L and 129R.

  The mounting portion 119 </ b> A is a lower straight portion of the inner peripheral edge of each slit 118. The mounting portion 119A extends substantially horizontally in the left-right direction while facing upward.

  The restricting portion 119 </ b> B is an upper straight portion of the inner peripheral edge of each slit 118. The restricting portion 119B faces the placement portion 119A and extends substantially horizontally in the left-right direction while facing downward.

  As shown in FIGS. 8-12, the 2nd member 120 has the base part 125, the support part 121, the latching | locking part 123, the hook parts 129L and 129R, and the contact parts 127L and 127R.

  The base 125 has a substantially rectangular plate shape that is long in the left-right direction. The base 125 has a first surface 125F and a second surface 125B facing away from the first surface 125F. The first surface 125F is a surface facing the outdoor direction, and the second surface 125B is a surface facing the indoor direction. The base portion 125 is provided with a plurality of second fixing holes 125H for inserting nails, screws or the like as fasteners.

  The support part 121 protrudes from the upper end edge of the base part 125 to the first surface 125F side, and extends in the left-right direction.

  The locking portion 123 is bent from a substantially central portion of the front end edge of the support portion 121, protrudes downward, and extends in the left-right direction. The locking portion 123 has a tapered shape in which the lower and left corners and the lower and right corners are cut off and tapered downward. In addition, it can also be set as the circular arc shape which bulges the lower end edge of the latching | locking part 123 below.

  The hook portions 129L and 129R are formed by cutting and raising the left and right portions on the upper edge side of the base portion 125. That is, the hook portions 129L and 129R are bent from the protruding position where the support portion 121 protrudes from the base portion 125. The hook portions 129 </ b> L and 129 </ b> R are bent in the same downward direction as the locking portion 123 after protruding from the upper end edge of the base portion 125 toward the second surface 125 </ b> B.

  As shown in FIG. 11, the length L129 in which the hook portions 129L and 129R extend downward is set shorter than the length L123 in which the locking portion 123 extends downward. The thicknesses of the hook portions 129L and 129R are set smaller than the vertical width of the slit 118. The distance between the substantially rectangular plate-like portions extending downwardly of the hook portions 129L and 129R and the second surface 125B of the base portion 125 in the indoor / outdoor direction is set slightly larger than the plate thickness of the placement portion 119A of the first member 110. Has been.

  Note that the hooking portions 129L and 129R are located at the upper edge of the base portion 125, that is, at the protruding position where the support portion 121 protrudes from the base portion 125, or the protruding position thereof, in order to eliminate the portion protruding above the first member 110. On the other hand, it is formed downward from a position biased downward.

  As is apparent from a comparison between the locking portion 123 shown in FIG. 9 and the hooking portions 129L and 129R shown in FIG. 10, the area of the locking portion 123 is the area of the hooking portion 129L and the area of the hooking portion 129R. It is set larger than the sum. This is because the member constituting the outer wall plate 2 is usually less strong than the member constituting the first member 110 and is therefore preferably supported by the locking portion 123 having a large area.

  As shown in FIGS. 8 to 12, the contact portions 127 </ b> L and 127 </ b> R protrude downward from the left and right portions of the tip edge of the support portion 121 and extend in the left-right direction. The contact portions 127L and 127R have a predetermined interval in the indoor / outdoor direction between the first surface 125F and the base portion 125, and are closer to the first surface 125F of the base portion 125 than the locking portion 123. is there. The distance between the contact portions 127L and 127R and the locking portion 123 is set slightly larger than the distance from a groove portion 2S of the outer wall plate 2 to be described later to the back surface 2B.

  Next, a construction method for supporting the specific end surface 2P of the outer wall plate 2 using the fixture 100 having such a configuration will be described. In this construction method, the first step, the second step, and the third step are performed, and the groove forming step is performed before the second step. In addition, you may implement a groove part formation process before a 1st process.

  In the first step, as shown in FIGS. 6 and 7, the fixing portion 115 of the first member 110 is fixed to the structure 8. More specifically, the top wall 113 of the first member 110 is brought into contact with the bottom wall 81, which is the downward surface of the aluminum sash 80, or a slight gap is secured between the two. A plurality of operations for screwing screws 110B as fasteners into the first fixing holes 115H of the fixing portion 115 with the waterproof sheet 6 and the waterproof tape 6T interposed between the fixing portion 115 and the structure 8 are performed. The fixing portion 115 is firmly fixed to the structural body 8 by performing the above.

  In a state where the fixing portion 115 is fixed to the structure 8, the support portion 114 is separated from the structure 8 in the outdoor direction. The space surrounded by the connecting portion 111, the support portion 114, and the top surface portion 113 can be vented to the outside by the slit 118 and the through hole 114H.

  Next, in the groove portion forming step, the outer wall plate 2 is cut to a size suitable for the bottom wall portion 81 of the aluminum sash 80 described above. Thereby, the back side up-and-down joining part 24 of the outer wall board 2 is cut off, and the specific end surface 2P is formed.

  And the groove part 2S is formed in the specific end surface 2P of the outer wall board 2 by groove processing. More specifically, an electric circular saw or the like that rotates a circular rotary blade with a motor is used, and the groove 2S is cut into the specific end surface 2P of the outer wall plate 2 by the rotary blade. Accordingly, as shown in FIG. 13, the bottom surface 2T of the groove 2S is recessed in an arc shape, the center portion is deeper, and becomes shallower toward the left end and the right end. As shown in FIG. 14, the interval between the opposing inner surfaces of the groove 2 </ b> S is set slightly larger than the plate thickness of the locking portion 123.

  The number and position of the groove portions 2S formed on the specific end surface 2P of the outer wall plate 2 are appropriately set according to the position of the placement portion 119A of the first member 110 fixed to the structure 8 by the first step. .

  Next, in the second step, the front side vertical joint 23 formed at the lower end of the outer wall plate 2 is supported by the tension starting fixture 60 shown in FIG. 4 or the vertical joint fixture 70 shown in FIG. Then, as shown in FIGS. 7, 13, and 14, the locking portion 123 of the second member 120 is inserted into the groove 2 </ b> S of the specific end surface 2 </ b> P of the outer wall plate 2. At this time, as shown in FIG. 13, the tapered locking portion 123 extends along the bottom surface 2 </ b> T that is recessed in the arc shape of the groove 2 </ b> S. Further, as shown in FIGS. 7 and 14, the locking portion 123 is sandwiched between the opposing inner side surfaces of the groove portion 2S. Further, the contact portions 127 </ b> L and 127 </ b> R are in contact with the back surface 2 </ b> B of the outer wall plate 2.

  Next, in the third step, as shown in FIGS. 7 and 14, the second surface 125 </ b> B of the base portion 125 of the second member 120 is brought into contact with the support portion 114 of the first member 110, and the second member 120 is hooked. The portions 129L and 129R are inserted into the slits 118 of the first member 110, and the hooking portions 129L and 129R are hooked on the placement portion 119A of the slit 118. As a result, the second member 120 sandwiches the vicinity of the mounting portion 119 </ b> A in the support portion 114 between the second surface 125 </ b> B of the base portion 125 and the substantially rectangular plate-like portion extending downward from the hook portions 129 </ b> L and 129 </ b> R.

  At this time, the hooking portions 129 </ b> L and 129 </ b> R are prevented from easily falling off the slit 118 by the restriction portion 119 </ b> B above the slit 118.

  Thus, the first member 110 suitably holds the base portion 125 and the hooking portions 129L and 129R of the second member 120, and the locking portion 123 and the contact portions 127L and 127R of the second member 120 specify the outer wall plate 2. The end surface 2P is suitably locked. Thereby, the specific end surface 2P of the outer wall board 2 can be favorably supported in a state of being adjacent to the window frame 8W from below.

  After the third step, a back-up material 89 made of foamed resin or the like is inserted into the gap between the bottom wall portion 81 of the aluminum sash 80 and the specific end surface 2P of the outer wall plate 2, and further, the sealing material 88 is filled. . A concealing portion 82 that hangs downward from the bottom wall portion 81 is formed on the tip side of the aluminum sash 80. A length L82 from the bottom wall portion 81 to the lower end of the concealing portion 82 is set to be longer than an interval S1 between the bottom wall portion 81 of the aluminum sash 80 and the specific end surface 2P of the outer wall plate 2. Since the sealing member 88 is concealed by such a concealing portion 82, the beauty of the periphery of the aluminum sash 80 and the specific end surface 2P of the outer wall plate 2 is improved.

  In addition, as shown in FIG. 6, a screw 120 </ b> B as a fastener can be inserted into the second fixing hole 125 </ b> H to fasten the base portion 125 of the second member 120 to the support portion 114 of the first member 110.

  The second fixing hole 125H is used when the second member 120 is attached to the first member 110 in the upside down direction and the outer wall plate 2 is supported from below through a groove formed on the lower surface of the outer wall plate 2. It can also be used.

<Effect>
According to the fixture 100 of the outer wall plate 2 and the method of constructing the outer wall plate 2 according to the first embodiment, as shown in FIGS. 6 and 7, the fixing portion 115 of the first member 110 is fixed to the building structure 8. Keep it. When fixing the specific end surface 2P on the upper side of the outer wall plate 2, the engaging portion 123 of the second member 120 is inserted into the groove portion 2S formed on the specific end surface 2P of the outer wall plate 2, and the back surface 2B from the groove portion 2S of the outer wall plate 2 is inserted. It is assumed that the portion up to the side is located between the locking portion 123 and the base portion 125. Then, the second member 120 is attached to the first member 110 fixed to the structure 8. At this time, the hooking portions 129L and 129R of the second member 120 are inserted into the slits 118 of the first member 110, and the hooking portions 129L and 129R are hooked on the mounting portion 119A of the slit 118, together with the second member 120. The outer wall plate 2 is attached to the structure 8 via the first member 110.

  Here, as shown in FIG. 7, the slit 118 opens toward the outdoor direction of the building, and the hook portions 129 </ b> L and 129 </ b> R can be inserted into the slit 118 of the first member 110. As shown, the length L129 is shorter than the length L123 of the locking portion 123. For this reason, as shown in FIG. 7, the hook portions 129 </ b> L and 129 </ b> R of the second member 120 are hooked on the mounting portion 119 </ b> A of the slit 118 without almost sliding the second member 120 upward with respect to the outer wall plate 2. Thus, the second member 120 can be attached to the first member 110 together with the outer wall plate 2.

  Further, the hooking portions 129L and 129R are set to a length L129 shorter than the length L123 of the locking portion 123, but by the restricting portion 119B located on the opposite side of the mounting portion 119A of the slit 118. Since the hook portions 129 </ b> L and 129 </ b> R are regulated so as not to come off from the fixing portion 115, it is possible to prevent the second member 120 from being detached from the first member 110. On the other hand, the engaging portion 123 inserted into the groove 2S of the outer wall plate 2 is longer than the hooking portions 129L and 129R, so that the outer wall plate 2 can be sufficiently supported.

  Furthermore, the hook portions 129L and 129R are bent from the protruding position where the support portion 121 protrudes from the base portion 125. For this reason, when the outer wall plate 2 is attached to the structure 8 together with the second member 120 via the first member 110, the position substantially the same as the upper surface of the outer wall plate 2 may be the uppermost position of the second member 120. In other words, the second member 120 has a small configuration with no excess portion above the second member 120. For this reason, when attaching the 2nd member 120 between members, such as aluminum sash 80 which comprises lower sides, such as the window frame 8W of the structure 8, extra space is not required. Specifically, as shown in FIG. 7, the distance S <b> 1 between the bottom wall portion 81 of the aluminum sash 80 and the specific end surface 2 </ b> P of the outer wall plate 2 can be reduced.

  As described above, when attaching the second member 120 to the first member 110 without largely moving the second member 120, there is no extra portion above the second member 120, so the upper end of the first member 110 is An unnecessary gap is not required between the portion and the member such as the window frame 8W of the structure 8. For this reason, since the part to which the outer wall board 2 is not attached can be minimized, not only the aesthetics are improved, but also the use of the sealing material 88 can be minimized, and the aesthetics are also improved in this respect.

  Therefore, according to the fixture 100 of the outer wall plate 2 and the construction method of the outer wall plate 2 of the first embodiment, it is possible to improve the aesthetic appearance of the entire wall including the periphery of the member such as the window frame 8W. Moreover, in this fixture 100 and construction method, while repair work of the outer wall board 2 resulting from a fastener can be omitted, since the usage-amount of the sealing material 88 can be reduced, workability | operativity can also be improved.

  Further, in this fixture 100 and the construction method, when the outer wall plate 2 is attached to the structure 8 together with the second member 120 via the first member 110, the contact portions 127 </ b> L and 127 </ b> R of the second member 120 are the outer wall plate 2. By abutting on the back surface 2B, a ventilation layer can be secured by the distance between the base portion 125 and the abutting portions 127L and 127R. Further, when the locking portion 123 of the second member 120 is inserted into the groove portion 2S of the outer wall plate 2, the portions from the groove portion 2S to the back surface 2B side of the outer wall plate 2 are connected to the locking portion 123 and the contact portions 127L and 127R. The 2nd member 120 is attached to the outer wall board 2 in the state pinched | interposed between the mutually opposing side surfaces. For this reason, when attaching the outer wall board 2 to the first member 110 fixed to the structure 8 together with the second member 120, the second member 120 can be prevented from falling from the outer wall board 2, so that the operator can remove the outer wall board 2. Can be easily performed.

  Furthermore, in this fixture 100 and the construction method, the contact portions 127L and 127R of the second member 120 are bent from the support portion 121 in the same downward direction as the locking portion 123. It is formed on both sides in the width direction. Thereby, even if the clearance gap between the latching | locking part 123 and the contact parts 127L and 127R is small, as shown in FIG. 14, seeing the 2nd member 120 from upper direction, the contact parts 127L and 127R, and the latching | locking part 123 Can be easily recognized, so that the locking portion 123 can be easily inserted into the groove portion 2S of the outer wall plate 2.

  Further, in the fixture 100 and the construction method, as shown in FIG. 14 and the like, the hook portions 129L and 129R of the second member 120 are on the second surface 125B side opposite to the contact portions 127L and 127R in the base portion 125. 2, the contact portion 127 </ b> L and 127 </ b> R on both sides of the locking portion 123 is disposed between the contact portion 127 </ b> L and 127 </ b> R. The positions of the hooks 129L and 129R are easy to grasp. For this reason, even when attaching the outer wall plate 2 in a narrow region such as the window frame 8W, the operation becomes easy.

  Furthermore, in this fixture 100 and construction method, as shown in FIGS. 6 and 7, the support portion 114 is separated from the fixed portion 115 by a predetermined distance by the connecting portion 111 of the first member 110. At the same time, when the outer wall plate 2 is attached to the structure 8 via the first member 110, a space is formed between the back surface 2B of the outer wall plate 2 and the fixing portion 115, and a ventilation layer can be secured.

  Moreover, in this fixture 100 and construction method, the through-hole 114H provided in the connection part 111 of the 1st member 110 has penetrated in the up-down direction. For this reason, in a state where the fixing portion 115 is fixed to the structure 8, the space surrounded by the connecting portion 111, the support portion 114, and the top surface portion 113 can be vented to the outside by the slit 118 and the through hole 114H. In addition, water drainage and ventilation around the fixture 100 can be performed satisfactorily.

  Further, in the fixture 100 and the construction method, the portion of the first member 110 excluding the fixing portion 115, that is, the connecting portion 111, the support portion 114, and the top surface portion 113 constitute a substantially C-shaped cross-sectional portion. This substantially C-shaped cross-sectional portion improves the rigidity of the support portion 114 and makes it difficult for the placement portion 119A of the slit 118 to be deformed. As a result, the second member 120 and the outer wall plate 2 can be firmly held by the support portion 114 of the first member 110.

  Moreover, in this fixture 100 and construction method, as shown in FIG.9 and FIG.10, the latching | locking part 123 of the 2nd member 120 inserted in the groove part 2S of the outer wall board 2 is longer than the hook parts 129L and 129R. In addition, the area is larger than the hooks 129L and 129R. For this reason, the fixture 100 can fully support the outer wall plate 2. As a result, even if the outer wall plate 2 vibrates due to wind pressure or the like, the outer wall plate 2 can be supported in a large area, so that it is possible to cause a crack or the like in the portion of the outer wall plate 2 where the groove 2S is formed. Can be prevented.

  Further, in the fixture 100 and the construction method, the base 125 of the second member 120 is provided with a second fixing hole 125H for allowing the fastener to pass therethrough. For this reason, instead of the hooking portions 129L and 129R, a screw or the like as a fastener is inserted into the second fixing hole 125H so that the locking portion 123 of the second member 120 faces upward, and the second member 120 is attached to the first member 110. By fixing, the outer wall plate 2 can also be supported from below via a groove formed on the lower surface of the outer wall plate 2.

  Moreover, in this fixture 100 and construction method, at the time of construction, a part of outer wall board 2 is cut | disconnected according to an installation place, and the outer wall is formed by forming the groove part 2S in the specific end surface 2P which the outer wall board 2 cut | disconnected. The plate 2 can be suitably attached to the structure 8. The specific end surface 2P is particularly effective because it is an end surface obtained by cutting off the back side vertical joint portion 24 of the outer wall plate 2 in accordance with the window frame 8W or the like. Further, the groove 2S in which the bottom surface 2T is recessed in an arc shape can be easily formed by cutting using a rotary blade.
