However, in the above-mentioned conventional mounting tool, it is necessary to secure a large working space above the plate material for completely fitting the insertion piece of the engaging metal fitting into the receiving portion of the fixing metal fitting. Specifically, when the plate material is attached below the window frame or the like, it is necessary to increase the distance between the lower end edge of the window frame or the like and the upper end surface of the plate material. As the portion where the plate material does not exist becomes large in this way, the aesthetic appearance of the wall is spoiled.

Further, since the distance between the plate material and the window frame or the like is widened, the amount of the sealing material used to fill the joints is likely to increase, and eventually, problems such as breakage, peeling, and dirt of the sealing material are likely to occur. As a result, this fixture has a problem that it is difficult to improve the aesthetic appearance around the fixture in the plate material.

The present invention has been made in view of the above-mentioned conventional circumstances, and provides a plate material mounting tool and a plate material construction method capable of improving the aesthetic appearance of the entire wall including the periphery of a member such as a window frame. It is an issue to be solved.

The connecting portion 111 is provided with a plurality of through holes 114H penetrating in the vertical direction.

The lower end edge of the support portion 114 is connected to the tip end edge of the connecting portion 111, and extends substantially parallel to the fixed portion 115, that is, in a flat plate shape in the vertical and horizontal directions to reach the upper end edge.

The top surface portion 113 is connected to the upper end edge of the support portion 114, is bent 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 formed in the support portion 114, and each of the slits 118 extends long in the left-right direction. The number and spacing of the slits 118 are set to a size necessary and sufficient for the hooking portions 129L and 129R, which will be described later, to be inserted. That is, it is set to be slightly larger than the thickness of the plates constituting the hooking portions 129L and 129R.

The mounting portion 119A is a straight portion on the lower side 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 119B is an upper straight portion of the inner peripheral edge of each slit 118. The regulating portion 119B faces the mounting portion 119A and extends substantially horizontally in the left-right direction while facing downward.

As shown in FIGS. 8 to 12, the second member 120 has a base portion 125, a support portion 121, a locking portion 123, a hook portion 129L and 129R, and a contact portion 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 the opposite side of 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 125 is provided with a plurality of second fixing holes 125H for inserting nails, screws, etc. as fasteners.

The support portion 121 projects from the upper end edge of the base portion 125 toward the first surface 125F and extends in the left-right direction.

The locking portion 123 bends from a substantially central portion of the tip edge of the support portion 121, projects downward, and extends in the left-right direction. The locking portion 123 has a tapered shape that tapers downward by cutting off the lower and left corners and the lower and right corners. It should be noted that the lower end edge of the locking portion 123 may be formed into an arc shape that bulges downward.

The hooking portions 129L and 129R are formed by cutting up two places on the left and right sides of the upper end edge side of the base portion 125. That is, the hooking portions 129L and 129R are bent from the protruding positions where the support portions 121 project from the base portion 125. The hooking portions 129L and 129R project downward from the upper end edge of the base portion 125 toward the second surface 125B, and then bend downward in the same manner as the locking portion 123.

As shown in FIG. 11, the length L129 in which the hooking portions 129L and 129R extend downward is set shorter than the length L123 in which the locking portion 123 extends downward. The thickness of the hooking portions 129L and 129R is set to be smaller than the vertical width of the slit 118. The distance between the substantially rectangular plate-shaped portion extending downward of the hooking portions 129L and 129R and the second surface 125B of the base portion 125 in the indoor and outdoor directions is set to be slightly larger than the plate thickness of the mounting portion 119A of the first member 110. Has been done.

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

As is clear by comparing the locking portion 123 shown in FIG. 9 with 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 members constituting the outer wall plate 2 are usually smaller in strength than the members constituting the first member 110, and therefore are preferably supported by the locking portion 123 having a large area.

As shown in FIGS. 8 to 12, the contact portions 127L and 127R project downward from the left portion and the right portion 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 distance in the indoor / outdoor direction from the first surface 125F of the base 125, and are located closer to the first surface 125F of the base 125 than the locking portion 123. be. The distance between the contact portions 127L and 127R and the locking portion 123 is set to be slightly larger than the distance from the groove portion 2S of the outer wall plate 2 to the back surface 2B, which will be described later.

Next, a construction method for supporting the specific end surface 2P of the outer wall plate 2 by 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 carried out, and the groove forming step is carried out before the second step. The groove forming step may be carried out before the first step.

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 surface portion 113 of the first member 110 is brought into contact with the bottom wall portion 81, which is the downward surface of the aluminum sash 80, from below, or a slight gap is secured between the two. Then, with the waterproof sheet 6 and the waterproof tape 6T interposed between the fixing portion 115 and the structure 8, a plurality of operations of screwing the screw 110B as a fastener into the first fixing hole 115H of the fixing portion 115 are performed. By doing so, the fixing portion 115 is firmly fixed to the structure 8.

In the 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 supporting portion 114, and the top surface portion 113 can be ventilated to the outside by the slit 118 and the through hole 114H.

Next, in the groove 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. As a result, the upper and lower joints 24 on the back side of the outer wall plate 2 are cut off, and the specific end surface 2P is formed.

Then, a groove portion 2S is formed on the specific end surface 2P of the outer wall plate 2 by grooving. More specifically, an electric circular saw or the like that rotates a circular rotary blade with a motor is used, and the groove portion 2S is cut into the specific end surface 2P of the outer wall plate 2 by the rotary blade. As a result, as shown in FIG. 13, the groove portion 2S has a bottom surface 2T recessed in an arc shape, the central portion is deep, and the groove portion 2S becomes shallower toward the left end and the right end. As shown in FIG. 14, the distance between the facing inner side surfaces of the groove portions 2S is set to be slightly larger than the plate thickness of the locking portion 123.

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

Next, in the second step, the front upper and lower joints 23 formed at the lower end of the outer wall plate 2 are supported by the tension start attachment 60 shown in FIG. 4 or the upper and lower joint attachment 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 portion 2S of the specific end surface 2P of the outer wall plate 2. At this time, as shown in FIG. 13, the tapered locking portion 123 is along the bottom surface 2T recessed in an arc shape of the groove portion 2S. Further, as shown in FIGS. 7 and 14, the locking portion 123 is sandwiched between the opposite inner side surfaces of the groove portion 2S. Further, the contact portions 127L and 127R come into contact with the back surface 2B of the outer wall plate 2.

Next, in the third step, as shown in FIGS. 7 and 14, the second surface 125B 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 slit 118 of the first member 110, and the hooking portions 129L and 129R are hooked on the mounting portion 119A of the slit 118. As a result, the second member 120 sandwiches the vicinity of the mounting portion 119A in the support portion 114 between the second surface 125B of the base portion 125 and the substantially rectangular plate-shaped portion extending downward of the hooking portions 129L and 129R.

At this time, the restricting portion 119B on the upper side of the slit 118 prevents the hooking portions 129L and 129R from easily falling off from the slit 118.

In this way, the first member 110 preferably 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 portion 127L and 127R of the second member 120 specify the outer wall plate 2. The end face 2P is suitably locked. As a result, the specific end surface 2P of the outer wall plate 2 can be satisfactorily supported in a state of being adjacent to the window frame 8W from below.

After the third step, the backup 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. .. On the tip end side of the aluminum sash 80, a concealing portion 82 that hangs down from the bottom wall portion 81 is formed. The length L82 from the bottom wall portion 81 to the lower end of the concealing portion 82 is set to be longer than the distance 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 material 88 is concealed by such a concealing portion 82, the aesthetic appearance around the specific end surface 2P of the aluminum sash 80 and the outer wall plate 2 is improved.

Further, as shown in FIG. 6, a screw 120B as a fastener can be inserted into the second fixing hole 125H 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 up-down direction and the outer wall plate 2 is supported from below via a groove formed on the lower surface of the outer wall plate 2. It can also be used.

<Action effect>
According to the method of constructing the fixture 100 of the outer wall plate 2 and the outer wall plate 2 of the first embodiment, as shown in FIGS. 6 and 7, the fixing portion 115 of the first member 110 is fixed to the structure 8 of the building. Keep it. When fixing the specific end surface 2P on the upper side of the outer wall plate 2, the locking portion 123 of the second member 120 is inserted into the groove portion 2S formed in the specific end surface 2P of the outer wall plate 2, and the groove portion 2S of the outer wall plate 2 to the back surface 2B. 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, by inserting the hooking portions 129L and 129R of the second member 120 into the slit 118 of the first member 110 and hooking the hooking portions 129L and 129R to the mounting portion 119A of the slit 118, the hooking portions 129L and 129R are hooked 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 is open toward the outside of the building, and the hooking portions 129L and 129R can be inserted into the slit 118 of the first member 110, and FIG. 11 As shown in the above, the length L129 is shorter than the length L123 of the locking portion 123. Therefore, as shown in FIG. 7, the hooking portions 129L and 129R of the second member 120 are hooked on the mounting portion 119A of the slit 118 without sliding the second member 120 upward with respect to the outer wall plate 2. 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 are located above the restricting portion 119B opposite to the mounting portion 119A of the slit 118. Since the hooking portions 129L and 129R are regulated so as not to come off from the fixing portion 115, it is possible to prevent the second member 120 from coming off from the first member 110. On the other hand, since the locking portion 123 inserted into the groove portion 2S of the outer wall plate 2 is longer than the hooking portions 129L and 129R, the outer wall plate 2 can be sufficiently supported.

Further, the hooking portions 129L and 129R are bent from the protruding positions where the support portions 121 project from the base portion 125. Therefore, 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 set as the uppermost position of the second member 120. It is possible to have a compact structure with no extra portion above the second member 120. Therefore, no extra space is required when the second member 120 is attached to the member such as the aluminum sash 80 constituting the lower side of the window frame 8W or the like of the structure 8. Specifically, as shown in FIG. 7, the distance S1 between the bottom wall portion 81 of the aluminum sash 80 and the specific end surface 2P of the outer wall plate 2 can be reduced.

As described above, since there is no extra portion above the second member 120 when the second member 120 is attached to the first member 110 without significantly moving the second member 120, the upper end of the first member 110 is used. No unnecessary gap is required between the portion and a member such as the window frame 8W of the structure 8. Therefore, since the portion where the outer wall plate 2 cannot be attached can be minimized, not only the aesthetic appearance can be improved, but also the use of the sealing material 88 can be minimized, and the aesthetic appearance is also improved from this point.

Therefore, according to the method of constructing the fixture 100 of the outer wall plate 2 and 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. Further, in the attachment 100 and the construction method, the repair work of the outer wall plate 2 caused by the fastener can be omitted, and the amount of the sealing material 88 used can be reduced, so that the workability can be improved.

Further, in the attachment 100 and the construction method, when the outer wall plate 2 is attached to the structure 8 via the first member 110 together with the second member 120, the contact portions 127L and 127R of the second member 120 are attached to the outer wall plate 2. By abutting on the back surface 2B of the above, the ventilation layer can be secured by the distance between the base 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 portion of the outer wall plate 2 from the groove portion 2S to the back surface 2B side is formed by the locking portion 123 and the contact portion 127L and 127R. The second member 120 is attached to the outer wall plate 2 in a state of being sandwiched between the side surfaces facing each other. Therefore, when the outer wall plate 2 is attached 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 plate 2, so that the operator can prevent the outer wall plate 2 from falling. Can be easily installed.

Further, in the attachment 100 and the construction method, the contact portions 127L and 127R of the second member 120 are formed by bending downward from the support portion 121 in the same direction as the locking portion 123, and the locking portion 123 is formed. It is formed on both sides in the width direction. As a result, even if the gap between the locking portion 123 and the contact portion 127L and 127R is small, as shown in FIG. 14, the second member 120 is viewed from above with the contact portion 127L, 127R and the locking portion 123. Is easily visible, so that the locking portion 123 can be easily inserted into the groove portion 2S of the outer wall plate 2.

Further, in the attachment 100 and the construction method, as shown in FIG. 14 and the like, the hooking 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. Since it is arranged between the contact portions 127L and 127R on both sides of the locking portion 123, when the operator inserts the hooking portions 129L and 129R into the slit 118 of the first member 110, the back surface 2B side. It is easy to grasp the position of the hooking portion 129L and 129R. Therefore, even when the outer wall plate 2 is attached in a narrow area with the window frame 8W or the like, the work becomes easy.

Further, in the attachment 100 and the 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, so that the second member 120 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.

Further, in the attachment 100 and the construction method, the through hole 114H provided in the connecting portion 111 of the first member 110 penetrates in the vertical direction. Therefore, 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 ventilated to the outside by the slit 118 and the through hole 114H. , Drainage and ventilation around the fixture 100 can be performed well.

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 form a substantially C-shaped cross-sectional shape portion. The substantially C-shaped cross-sectional shape portion improves the rigidity of the support portion 114, and the mounting portion 119A of the slit 118 is less likely to be deformed. As a result, the support portion 114 of the first member 110 can firmly hold the second member 120 and the outer wall plate 2.

Further, in the attachment 100 and the construction method, as shown in FIGS. 9 and 10, the locking portion 123 of the second member 120 inserted into the groove portion 2S of the outer wall plate 2 is longer than the hooking portions 129L and 129R. Not only that, the area is larger than that of the hooking portions 129L and 129R. Therefore, the fixture 100 can sufficiently 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 that cracks or the like occur in the portion of the outer wall plate 2 where the groove 2S is formed. Can be prevented.

Further, in the attachment 100 and the construction method, the base 125 of the second member 120 is provided with a second fixing hole 125H for inserting the fastener. Therefore, 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 becomes the first member 110. By fixing, the outer wall plate 2 can be supported from below via the groove formed on the lower surface of the outer wall plate 2.

Further, in the fixture 100 and the construction method, at the time of construction, a part of the outer wall plate 2 is cut according to the installation location, and the groove portion 2S is formed on the cut specific end surface 2P of the outer wall plate 2 to form the outer wall thereof. 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 in which the upper and lower joint portions 24 on the back side of the outer wall plate 2 are cut off according to the window frame 8W or the like. Further, by cutting with a rotary blade, the groove portion 2S in which the bottom surface 2T is recessed in an arc shape can be easily formed.

Needless to say, it can be changed and applied.

For example, as shown in FIG. 22, in the fixture 200 of the second embodiment, the lower end surface of the left locking portion 223L of the second member 220 is changed to be inclined downward to the right, and the right locking portion is locked. The lower end surface of the portion 223R may be changed so as to be inclined downward to the left or right. That is, the locking portions 223L and 223R may be changed to a taber shape that tapers downward so as to be along the bottom surface 2T of the groove portion 2S. In this case, since the locking portions 223L and 223R can enter deep into the groove portion 2S, the locking portions 223L and 223R can reliably lock the specific end surface 2P of the outer wall plate 2. Further, in this case, since it is easy to secure an adjustment allowance in which the locking portions 223L and 223R can move in the longitudinal direction of the groove portion 2S, that is, in the left-right direction, it is possible to provide a margin for positioning the second member 220 with respect to the groove portion 2S. can.

In the first and second embodiments, the specific end surface 2P is the upper end surface of the outer wall plate 2 cut at the construction site, but may be cut and formed at the manufacturing stage.
