The present invention relates to an outer wall panel fixture for attaching an outer wall panel to a base material of a building , and an outer wall panel mounting structure.

  As a conventional outer wall panel fixture, for example, there is one shown in FIG. 14 (see, for example, Patent Document 1). As shown in the figure, the outer wall panel fixture 1 includes a panel attachment member 2 and first and second bolts 3 and 4 (the first bolt 3 is not shown in the figure). . The panel attachment member 2 has a base end 2b fastened and fixed to the outer wall panel 6 by first and second bolts 3 and 4 and nuts 5 and 5. In this state, the clamping portion of the panel attachment member 2 2a sandwiches an upper base material (angle) 7 with the outer wall panel 6. In this way, the upper part of the outer wall panel 6 can be attached to the upper base material 7. The upper base material 7 is welded to the beam 8 of the building.

JP-A-8-277593

  However, in the conventional outer wall panel fixture 1 shown in FIG. 18, when the building is shaken by an earthquake, for example, and the tightening of the first and second bolts 3 and 4 is loosened, as shown by a two-dot chain line, the panel mounting member 2 May rotate clockwise around the first bolt 3. As described above, when the panel mounting member 2 rotates and the clamping portion 2 a of the panel mounting member 2 is detached from the upper base material 7, the upper portion of the outer wall panel 6 may be detached from the upper base material 7.

  In order to prevent the panel mounting member 2 from rotating clockwise about the first bolt 3, a bolt hole is formed in the panel mounting member 2 instead of the notch 11, and the second bolt 4 is formed in the bolt hole. It is conceivable to pass through.

  However, if a bolt hole is used instead of the notch 11, the second bolt 4 cannot be inserted into the bolt hole by rotating the panel mounting member 2 counterclockwise as shown in FIG. There is.

  Here, as shown in FIG. 17, the panel mounting member 2 is rotated counterclockwise about the first bolt 3 so that the second bolt 4 is engaged with the notch 11. If the panel mounting member 2 is temporarily fixed with the first and second bolts 3 and 4 at the mounting position shown in FIG. This is because the outer wall panel 6 cannot be disposed at the attachment positions of the upper and lower base materials 7 due to obstruction.

  It is also conceivable that the panel mounting member 2 is fastened and fixed to the upper part of the outer wall panel 6 with the first and second bolts 3 and 4 in a state where the outer wall panel 6 is disposed at the mounting positions of the upper and lower base materials 7. However, in a state where the outer wall panel 6 is disposed at the attachment positions of the upper and lower base materials 7, the nut 5 is disposed in the hollow portion 6a of the outer wall panel 6, and the first and second bolts 3 are disposed on the nuts 5, 5. In order to screw 4, it is necessary to use a special tool or a special nut that can be inserted into a predetermined position of the hollow portion 6 a and can be attached to that position, which increases costs.

The present invention has been made to solve the above-described problems. Even if the outer wall panel can be easily attached to the building base material, for example, the first and second bolts are loosened due to an earthquake. It is an object of the present invention to provide an outer wall panel attachment that can prevent the sandwiching portion of the panel attachment member from being detached from the base material , and an outer wall panel attachment structure that uses this outer wall panel attachment .

An outer wall panel attachment according to the present invention is an outer wall panel attachment for attaching a hollow outer wall panel to a base material of a building, a sandwiching part for sandwiching the base material between the outer wall panel, and a coupling with the sandwiching part A panel mounting member having a base end portion fixed to the outer wall panel by at least two first and second bolts, the base end portion including a bolt hole through which the first bolt is inserted; A notch portion formed with a width that allows the second bolt to enter and exit, and the back side portion of the notch portion is formed wider than the inlet portion, and the second bolt is provided on the back side portion. The first and second bolts are screwed into respective nuts disposed in the hollow portion of the outer wall panel , and further, between the base material and the clamping portion. Arranged and fixed to the base material A slide stopper is provided, and the slide stopper engages with an edge of the panel mounting member, so that the panel mounting member moves in one or both of the length directions with respect to the base material. This is characterized in that a protrusion for preventing the above is provided .

  When attaching the outer wall panel to the building base material using the outer wall panel fixture according to the present invention, for example, first, the first bolt is inserted into the respective bolt holes provided in the panel mounting member and the outer wall panel. The second bolt is inserted into a bolt hole provided in the outer wall panel, and the first and second bolts are screwed into the respective nuts arranged in the hollow portion of the outer wall panel. Then, the outer wall panel to which the panel mounting member is temporarily fixed is disposed at the mounting position with respect to the base material, and the panel mounting member is rotated around the first bolt, and the cut portion formed in the panel mounting member is inserted into the cut portion. Engage 2 bolts. Next, the disengagement prevention part provided in the 2nd volt | bolt is fitted in the back | inner side part of a notch | incision part, and a 1st and 2nd volt | bolt is fastened. In this way, the outer wall panel can be attached to the base material.

  According to the outer wall panel fitting attached in this way, even if the building is shaken due to an earthquake, for example, and the tightening of the first and second bolts is loosened, the come-off prevention portion provided on the second bolt is the cut portion. Since it is fitted to the back side portion of this, it is possible to prevent the cutout portion from rotating in the direction away from the second bolt by this slip-off preventing portion. Accordingly, the panel mounting member does not come off from the second bolt, and therefore does not come off from the base material. Therefore, the outer wall panel can be locked so as not to come off from the base material.

  Even when the nuts are arranged in the hollow portion of the outer wall panel, the first and second bolts can be easily screwed to the respective nuts. This is because the operation of screwing the first and second bolts into the nut can be performed at the stage before the outer wall panel is disposed at the attachment position with respect to the base material, for example, on the ground. This is because it is easy to attach a nut to the hollow portion of the outer wall panel in the state.

Furthermore, even when a force that moves the panel mounting member in one or both of its length directions is applied to the base material due to an earthquake, for example, the protrusion of the slide stopper fixed to the base material is Since it is engaged with the edge, the panel mounting member can be prevented from moving in the length direction with respect to the base material. This can prevent the positional relationship between the base material and the outer wall panel from shifting.

  And in the outer wall panel fixture which concerns on this invention, it is good for the said coming-off prevention part to be a disk shaped body which the said 2nd volt | bolt penetrates. Thus, by making the shape of the locking part a disk-shaped body, the locking part can be easily fitted to the back side of the cut part regardless of the orientation.

  In the outer wall panel fixture according to the present invention, an operation management reference line indicating the mounting position of the panel mounting member with respect to the base material may be displayed on the outer surface of the clamping portion of the panel mounting member. When the panel mounting member is attached to the outer wall panel with the first and second bolts so that the enforcement control reference line substantially coincides with, for example, the edge of the base material, the positional relationship between the panel mounting member and the base material due to, for example, an earthquake However, even if there is a deviation within a predetermined range, the panel mounting member can be prevented from being detached from the base material. Therefore, the panel attachment member can be easily attached to an appropriate position of the outer wall panel.

The outer wall panel mounting structure according to the present invention is an outer wall panel mounting structure in which a hollow outer wall panel is mounted to a building base material by a panel mounting member, and the sandwiching portion provided in the panel mounting member and the outer wall panel The base material is sandwiched between and the base end connected to the holding part is fixed to the outer wall panel with at least two first and second bolts, and the first bolt is inserted into the base end. And a notch portion formed with a width that allows the second bolt to enter and exit, and a back side portion of the notch portion is formed wider than an inlet portion thereof, A locking part provided on two bolts is fitted, and the first and second bolts are screwed into respective nuts arranged in the hollow part of the outer wall panel , and further, the base material and the clamping Between departments The slide stopper is disposed and fixed to the base material, and the slide stopper engages with an edge of the panel mounting member so that the panel mounting member has a length relative to the base material. A protrusion for preventing movement in one or both directions is provided .

  According to this outer wall panel mounting structure, as described above, the outer wall panel mounting tool of the present invention is used to provide the same operation as that of the structure in which the outer wall panel is mounted on the base material.

According to the outer wall panel mounting tool and the outer wall panel mounting structure according to the present invention, the outer wall panel mounting tool can be temporarily fixed to the outer wall panel at a stage before the outer wall panel is disposed at the mounting position with respect to the base material. Therefore, the outer wall panel arranged at the attachment position with respect to the base material can be easily attached to the base material using the temporarily fixed outer wall panel fixture.

  And even if the first and second bolts that fasten the panel mounting member to the outer wall panel are loosened by, for example, an earthquake, the panel mounting member can be prevented from being detached from the base material by the detachment preventing portion. It can prevent reliably that a panel remove | deviates from a base material.

  Hereinafter, an embodiment of an outer wall panel fixture according to the present invention will be described with reference to FIGS. And in this embodiment, the mounting structure of the outer wall panel using this outer wall panel mounting tool 12, and the method of mounting the outer wall panel 6 to the upper and lower base materials 13, 14 using this outer wall panel mounting tool 12 Will be explained. As shown in FIG. 1, the outer wall panel fixture 12 can attach the outer wall panel 6 to an upper base material (for example, an angle) 13 and a lower base material (an angle, see FIG. 10) 14 of a building. The panel mounting member 15 and the first and second bolts 3 and 4 are provided (the first bolt 3 is not shown in the figure). The upper base material 13 and the lower base material 14 are welded to the beam 8 of the building via a bracket (see FIG. 10) 16. The outer wall panel 6 is, for example, a hollow extruded cement board.

  As shown in FIGS. 2A and 2B, the panel mounting member 15 connects the lower edge of the sandwiching portion 18 of the substantially trapezoidal plate-like body and the upper edge of the base end portion 19 of the substantially rectangular plate-like body. The sandwiching portion 18 and the base end portion 19 are parallel to each other and arranged with a predetermined interval K therebetween.

  The sandwiching portion 18 is, for example, a portion that sandwiches the upper base material 13, and as shown in FIG. 2A, the left corner of the lower edge is formed at a substantially right angle, and the right corner is approximately 45 °. Is formed. And on the surface of the clamping part 18, two enforcement control reference lines 21 and 21 are displayed in parallel with the lower edge part. The reference line 21 may be formed by a groove, for example.

  The base end portion 19 is a portion fixed to the outer wall panel 6. As shown in FIG. 2A, a bolt hole 22 through which the first bolt 3 is inserted is formed on the left side, and this base is formed on the right side. A notch 23 that opens at the lower edge of the end 19 is formed. The cut portion 23 is formed with a lateral width W1 that allows the second bolt 4 to enter and exit, and a substantially circular back side portion 24 is formed on the back side of the cut portion 23. The back side portion 24 is formed with a width W2 wider than that of the inlet portion, and is formed to have a size that allows the slip prevention portion 25 shown in FIGS. 3B and 3C to be fitted. The detachment preventing portion 25 is a disk-shaped body having a diameter W3 (<W2), and has an insertion hole 25a through which the second bolt 4 is inserted at the center. Further, as shown in FIG. 3 (b), a spring washer 26, a washer 27 and a detachment preventing portion 25 are inserted into the second bolt 4 from the bolt head side.

  FIG. 1 shows an example in which the upper part of the outer wall panel 6 is attached to the upper base material 13 by the outer wall panel fixture 12, but the outer wall panel 6 has a mounting structure that is symmetrical with the mounting structure of the outer wall panel 6 shown in FIG. The lower part of the panel 6 is also attached to the lower base material 14 by the outer wall panel fixture 12.

  Next, with reference to FIGS. 5 to 9, a procedure for attaching the upper portion of the outer wall panel 6 to the upper base material 13 using the outer wall panel fixture 12 will be described. First, as shown in FIG. 5, for example, the first bolt 3 is attached to the panel mounting member 15 and the outer wall panel 6 at a stage before the outer wall panel 6 is disposed at the mounting positions with respect to the upper and lower base materials 13 and 14. The second bolt 4 is inserted into the bolt hole (see FIG. 6) 28 provided in the outer wall panel 6 while being inserted into the provided bolt holes 22 and 10. Then, the first and second bolts 3, 4 are screwed into the nuts 5, 5 arranged in the hollow portion 6 a of the outer wall panel 6. Note that a spring washer (not shown) 26, a washer 27, and a locking portion 25 are inserted into the first bolt 3, and a spring washer (not shown) 26 and a washer 27 are inserted into the second bolt 4. ing. The outer wall panel 6 has a hollow portion 6a formed therein, and nuts 5 and 5 having a substantially rectangular plate-like body are disposed in the hollow portion 6a.

  And the outer wall panel 6 to which the outer wall panel fixture 12 was temporarily fixed as shown in FIG. 5 is shown in FIG. 6 (the heads of the first and second bolts 3 and 4 are omitted). The upper and lower base materials 13 and 14 are arranged at predetermined mounting positions. However, FIG. 6 shows a state in which the upper part of the outer wall panel 6 is arranged at the attachment position of the upper base material 13. Next, as shown in FIGS. 6 to 8, the panel attachment member 15 is rotated clockwise around the first bolt 3 to form a cut portion (back side portion 24) 23 formed in the panel attachment member 15. The second bolt 4 is engaged. Next, as shown in FIG. 9, the first and second bolts 3, 4 are respectively fitted to the back side portion 24 of the cut-out portion 23 by fitting the detachment preventing portion 25 attached to the second bolt 4. Tighten to nuts 5 and 5. Thereby, the upper part of the outer wall panel 6 can be attached to the upper base material 13. Similarly, the lower part of the outer wall panel 6 can be attached to the lower base material 14 using another outer wall panel fixture 12.

  FIG. 1 shows a state in which the outer wall panel 6 is attached to the upper base material 13, and the base end portion 19 of the panel attachment member 15 has first and second bolts (the first bolt 3 does not appear in the figure). .) 3 and 4 and nuts 5 and 5 screwed to the first and second bolts 3 and 4 are fastened and fixed to the upper portion of the outer wall panel 6. In this state, the upper base material 13 is sandwiched between the sandwiching portion 18 of the panel mounting member 15 and the outer wall panel 6.

  According to the outer wall panel fixture 12 attached in this way, even if the building is shaken by an earthquake and the tightening of the first and second bolts 3 and 4 is loosened, as shown in FIG. 4 is fitted in the back side 24 of the cut-out portion 23, so that the cut-out portion 25 is rotated counterclockwise so that the cut-out portion 23 is removed from the second bolt 4. This can be prevented. As a result, the panel mounting member 15 does not come off from the second bolt 4, and therefore does not come off from the upper base material 13. Therefore, it is possible to reliably prevent the outer wall panel 6 from coming off from the upper base material 13. Can do.

  In addition, according to the outer wall panel fixture 12, the outer wall panel mounting structure, and the outer wall panel mounting method according to this embodiment, the stage before the outer wall panel 6 is disposed at the mounting positions with respect to the upper and lower base materials 13 and 14. Thus, as shown in FIG. 5, the outer wall panel fixture 12 can be temporarily fixed to the outer wall panel 6, so that it is attached to the upper and lower base materials 13, 14 as shown in FIGS. The outer wall panel 6 disposed at the position can be easily attached to the base materials 13 and 14 by using the temporarily fixed outer wall panel fixture 12.

  Furthermore, as shown in FIG. 9, since the stopper part 25 is formed as a disc-like body, the stopper part 25 can be easily formed on the substantially circular back side part 24 of the notch part 23 regardless of its orientation. Can be fitted.

  As shown in FIG. 5, the nuts 5, 5 to be screwed into the first and second bolts 3, 4 can be disposed in the hollow portion 6 a of the outer wall panel 6. As a result, the nuts 5 and 5 do not appear on the outer surface of the outer wall panel 6, and the aesthetic appearance can be improved. Even when the nuts 5 and 5 are thus arranged in the hollow portion 6a of the outer wall panel 6, the first and second bolts 3 and 4 can be easily screwed into the nuts 5 and 5, respectively. Therefore, the outer wall panel 6 can be easily attached to the upper and lower base materials 13 and 14. That is, the operation of screwing the first and second bolts 3 and 4 into the nuts 5 and 5 can be performed at a stage before the outer wall panel 6 is disposed at the mounting position with respect to the base materials 13 and 14, for example, on the ground. Because it can.

  FIG. 10 shows a state (vertical stretching method) in which the rectangular vertically long outer wall panel 6 is attached to the upper and lower base materials 13 and 14 using the outer wall panel fixture 12 shown in FIG. The upper and lower base materials 13 and 14 are horizontally arranged with a space therebetween and are welded to the beam 8 via the bracket 16. Then, two outer wall panel attachments 12 are attached to each of the upper part and the lower part of the outer wall panel 6. However, a notch 29 provided as an inclined side in the sandwiching part 18 of the panel mounting member 15 and a notch 23 provided in the base end 19 are formed on the right side as viewed from the front as shown in FIG. It may be formed on the left side as viewed from the front.

  Further, in this embodiment, as shown in FIG. 1, the sandwiching portion 18 of the panel mounting member 15 is attached so as to be brought into direct contact with and pressed against the upper base material 13. As shown in FIG. 4, the outer wall panel fixture 12 may be a slide stopper 30 disposed between the upper base material 13 and the sandwiching portion 18.

  As shown in FIGS. 4A and 4B, the slide stopper 30 is formed by bending one end of a rectangular plate-shaped portion 30a to form a protrusion 30b. For example, as shown in the enlarged view of part A in FIG. 10, the slide stopper 30 is provided so as to be welded to the upper base material 13 by the welded portion 31 and the protrusion 30 b is engaged with the left side edge of the clamping portion 18. used. As shown in FIG. 10, another outer wall panel fixture 12 that is symmetrical with the outer wall panel fixture 12 of the A portion is provided on the left side of the outer wall panel fixture 12 provided in the A portion. ing. The slide stopper 30 is provided on the outer wall panel fixture 12 so that the protrusion 30b engages with the right edge of the clamping portion 18.

  As shown in FIG. 10, according to at least the pair of left and right outer wall panel fixtures 12, 12 provided with the slide stopper 30, the panel attachment member 15 is in the length direction (horizontal) with respect to the upper base material 13 due to, for example, an earthquake. Even when a force that moves in one or both directions is applied, the protrusions 30b of the respective slide stoppers 30 welded (fixed) to the base material 13 are the left and right edges of the sandwiching portions 18 corresponding thereto. Therefore, the panel attachment member 15 can be prevented from moving in the length direction (horizontal direction) with respect to the upper base material 13. Thereby, it is possible to reliably prevent the positional relationship between the upper and lower base materials 13 and 14 and the outer wall panel 6 from shifting in the horizontal direction.

  FIG. 11 shows a state in which a rectangular outer wall panel 6 that is long in the horizontal direction is attached to the left and right base materials 33 and 34 using the outer wall panel fixture 12 shown in FIG. . The left and right base materials 33 and 34 are arranged in the vertical direction with a space therebetween and are welded to the column 35 via the bracket 17. Then, two outer wall panel fixtures 12 are attached to each of the left side portion and the right side portion of the outer wall panel 6.

  Further, in this embodiment, as shown in FIG. 10, the clamping portion 18 of the panel mounting member 15 is attached so as to be detachably pressed without being fixed to the upper and lower base materials 13, 14. As shown in the enlarged view of part B in FIG. 11, the holding part 18 of the lower panel attachment member 15 attached to the lower part of the outer wall panel 6 of the horizontal construction method is welded to the left and right base materials 33 and 34. May be. And it is good also as a structure which sandwiches packing (buffer material) 36 between each base material 33,34 on either side, and the outer wall panel 6. FIG.

  12 and 13, for example, the length of the outer wall panel 6 is 5,000 mm, the width is 1,200 mm, the distance between the outer wall panel attachments 12 and 12 attached in the width direction is 1,056 mm, and the interlayer displacement is 1 The amount of displacement of the outer wall panel fixture (panel mounting member 15) 12 attached to each point A, B, and C of the outer wall panel 6 is calculated, and the necessity of the outer wall panel fixture 12 is set. Measured dimensions and mounting positions will be described.

  FIG. 12A shows the case of the vertical stretching method shown in FIG. 10, and the panel mounting member 15 sandwiches the outer wall panel 6 between the upper and lower base materials 13 and 14 as shown in FIG. 1. It shall be. At the time of interlayer displacement, if the O point at the lower right of the outer wall panel 6 is locked to the fulcrum, the panel attachment members 15 attached to the points A, B and C are relative to the upper and lower base materials 13 and 14. Move on. As described above, even if the panel mounting member 15 attached to each point moves, the panel mounting member 15 can be prevented from being detached from the upper and lower base materials 13 and 14.

  Now, as shown in FIG. 12 (b), the panel mounting member 15 is fixed to the outer wall panel 6 with first and second bolts (not shown) 3, 4, and is displayed on the clamping portion 18 of the panel mounting member 15. It is assumed that the panel attachment member 15 is attached so that the edge portions 37 of the upper and lower base materials 13 and 14 are positioned between the two enforcement management reference lines 21 and 21 that are being used. For example, the interval c between the two execution management reference lines 21 is 10 mm, and the allowable movement amount a when the edge portions 37 of the upper and lower base materials 13 and 14 move in the direction toward the front end edge of the sandwiching portion 18. Is 15 mm or less, and the allowable movement amount b when the edge portions 37 of the upper and lower base materials 13 and 14 are moved in the direction from the sandwiching portion 18 toward the base end portion 19 is set to 15 mm or less. d is the minimum length required for the engagement between the clamping portion 18 of the panel mounting member 15 and the base materials 13 and 14 and is 15 mm.

  Here, as shown in FIG. 12 (b), the amount of movement in the vertical direction (Y direction) of the panel mounting member 15 attached to each point of A, B, and C at 1/100 interlayer displacement is +10 mm, Since it is −0.26 mm and +10.6 mm, they are within the ranges of allowable movement amounts a and b (15 mm or less), respectively. However, even if the panel attachment member 15 attached to each point of A, B, and C moves in the left-right direction (X direction), the clamping part 18 does not come off from the base materials 13, 14. Description is omitted.

  Fig.13 (a) is a case of the horizontal construction method shown in FIG. However, as shown in FIG. 11, the upper pair of panel attachment members 15 attached to the upper part of the outer wall panel 6 are not welded to the left and right base materials 33 and 34, and the lower pair of panels. It is assumed that the attachment member 15 is welded to the left and right base materials 33 and 34 by the welding portion 32. When the struts 38 parallel to the pillars 35 are inclined to the right and the outer wall panel 6 slides in the horizontal right direction at the time of interlayer displacement, the pair of upper panel mounting members 15 are moved in the horizontal right direction, and the left and right base materials It moves relative to 33 and 34 by X. Then, the pair of lower-side welded panel mounting members 15 rotate by θ around the welded portion 32 so that the back side portion 24 formed in the cut portion 23 of the panel mounting member 15 is in a substantially vertical direction. Further, the E moves relative to the outer wall panel 6 by E. Thus, even if the panel mounting member 15 attached to each of the four points moves or rotates (swings), the panel mounting member 15 is prevented from being detached from the left and right base materials 33 and 34. The panel mounting member 15 can be allowed to rotate.

  Now, as shown in FIGS. 13A and 13B, the panel mounting member 15 is fixed to the outer wall panel 6 with first and second bolts (not shown) 3 and 4, and this panel mounting member 15. The panel mounting member 15 is attached so that the edge portions 37 of the left and right base materials 33 and 34 are positioned between the two enforcement management reference lines 21 and 21 displayed on the sandwiching portion 18 Suppose that However, in the same manner as described above, for example, the interval c between the two enforcement management reference lines 21 and 21 shown in FIG. 13B is 10 mm, and the edge portions 37 of the left and right base materials 33 and 34 are located on the clamping portion 18. The allowable movement amount a when moving in the direction toward the distal end edge is 15 mm or less, and the allowable amount when the respective edge portions 37 of the left and right base materials 33 and 34 move in the direction from the clamping portion 18 toward the proximal end portion 19. The movement amount b is set to 15 mm or less. d is the minimum length required for the engagement between the clamping portion 18 of the panel mounting member 15 and the base materials 33 and 34, and is 15 mm. The gap f between the inner diameter of the back side portion 24 of the cut portion 23 and the outer diameter of the locking portion 25 is 1.5 mm. Moreover, as shown to Fig.13 (a), the dimension e from each edge part 37 of the right-and-left base materials 33 and 34 to the center of the back side part (cutting part 23) 24 is 50 mm.

  Here, as shown in FIG. 13B, the movement amount in the left-right direction (X direction) of the pair of upper panel mounting members 15 at 1/100 interlayer displacement is 9 mm. , B (15 mm or less). An amount E of the back side portion 24 of the cut portion 23 that moves vertically upward with respect to the locking portion 25 is 0.5 mm, and is within a range of an allowable movement amount f (1.5 mm or less). Yes. In this case, the welded panel attachment member 15 rotates about the welded portion 32 by θ (= 1/100 rad = 0.57 °).
