Description

  The present invention relates to an exterior material fixture applied to the mounting of an exterior material.

  In recent years, outer heat insulation has attracted attention as an effective means for improving heat insulation performance and preventing condensation. Specifically, the external heat insulation is to cover the concrete outer wall of the building frame with a heat insulating material and attach an exterior material to the outside via an air layer. The exterior material fixture used for this external heat insulation is disclosed by the following patent document 1, etc., for example.

  The exterior material fixture described in Patent Document 1 includes a bolt connected to a fixed bolt that is driven into and fixed to a concrete wall of a building frame, and a level (non-land) adjustment that is screwed to the free end side of the bolt. A trunk edge bracket having a function. And the trunk edge which extends along a concrete wall surface and should be equipped with an exterior material is attached to this trunk edge receiving metal fitting.

  In addition, when attaching an exterior material using such an exterior material attachment tool, in many cases, adjacent exterior materials are installed so as to be arranged in the same virtual plane, and the outer surface is a flat surface. Is done. And the height adjustment (non-landscape adjustment) of such an exterior material can be performed to a certain length with the trunk edge bracket of the said exterior material attachment tool.

However, if there are large irregularities such as beams or columns on the wall of the frame, the length of the unevenness adjustment becomes long, making it difficult to adjust with the trunk edge bracket, and bolts with different lengths can be used. There is a need to adopt. However, when a bolt with a long length is adopted, the moment load applied to the bolt increases due to the weight of the exterior material and its own weight, and thus it is necessary to consider the bolt strength. Therefore, the exterior material fixture disclosed in Patent Document 2 is provided with a support plate that reinforces the bolt in order to relieve the moment load applied to the bolt extending from the wall surface.

FIG. 2 is a plan view of the exterior material attachment shown in FIG. As shown in FIGS. 1 and 2, the exterior material fixture 10 </ b> A includes a bolt (support shaft) 11, a reinforcing member 13, a channel (trunk edge receiving member) 14, and a trunk edge 16. The exterior material fixture 10A is used, for example, when fixing a heat insulating material 20 made of glass wool to a concrete outer wall 18 of a building erected vertically and attaching an exterior material 22 to the concrete outer wall 18. It is an exterior tool.

  The bolt 11 is a linear bolt in which a male screw portion 12 is formed over the entire length. The bolt 11 is embedded in the concrete outer wall 18 with one end 11 a screwed into a hole-in anchor (anchor nut) 11 A embedded in the concrete outer wall 18, and the other end 11 b is exposed from the concrete outer wall 18. Then, it extends in the normal direction of the wall surface 18 a of the concrete outer wall 18. Hereinafter, for convenience of description, the extending direction (axial direction) of the bolt 11 is described as the X-axis direction, the vertical direction is defined as the Y-axis direction, and the direction orthogonal to the X-axis direction and the Y-axis direction is described as the Z-axis direction.

  The reinforcing member 13 includes a female screw portion 13 a attached to the bolt 11 and a pair of fixing portions 13 b fixed to the concrete outer wall 18. The female screw portion 13 a is a rectangular flat plate-like portion extending so as to be orthogonal to the axial direction (X direction) of the bolt 11, and a female screw that is screwed into the male screw portion 12 of the bolt 11 at the center thereof. A through hole 13c in which is formed is provided. And from each edge part which opposes the horizontal direction of the internal thread part 13a, the strip | belt-shaped fixing | fixed part 13b is extended to the wall surface a of the concrete outer wall 18. As shown in FIG. Each fixing portion 13b is inclined at a predetermined angle with respect to the axial direction of the bolt 11 in the horizontal plane so as to gradually move away from the bolt 11 as it approaches the concrete outer wall 18 from the female screw portion 13a. Each of the pair of fixing portions 13b and the concrete outer wall 18 are fixed by a fixing tool (not shown) such as a screw or a bolt. That is, the displacement of the female screw portion 13a relative to the concrete outer wall 18 is suppressed by the fixing portion 13b.

  Here, the female screw portion 13 a of the reinforcing member 13 is located closer to the exterior material 22 than the outer surface of the heat insulating material 20 (the surface on the exterior material 22 side). The bolt 11 between the female screw portion 13a and the heat insulating material 20 is provided with a heat insulating material fixing plate 23 inserted through the bolt 11, and the heat insulating material fixing plate 23 is provided with the heat insulating material 20. Is held on the concrete outer wall 18 of the building frame.

  The channel 14 includes a circular washer 24 and a trunk edge receiving metal fitting 26. The washer 24 has a cylindrical rivet nut 24a in which an internal thread portion 25 corresponding to the external thread portion 12 of the bolt 11 is formed on the inner peripheral surface, and a disk-shaped disc formed on the outer peripheral edge of the rivet nut 24a. It is comprised by the handle panel part 24b. Here, the rivet nut 24a has a female screw portion 25 on its inner peripheral surface engaged with the male screw portion 12 of the bolt 11, and the rivet nut 24a rotates relative to the bolt 11, The rivet nut 24a slides in the axial direction of the bolt 11 (X-axis direction). The rivet nut 24a is fixed by caulking with a handle panel portion 24b extending in the axial direction of the bolt 11, and the rivet nut 24a is also integrated when the handle panel portion 24b rotates about the axis of the bolt 11. To turn.

  The trunk edge receiving metal fitting 26 has a through hole 26a having a diameter slightly larger than the outer diameter of the rivet nut 24a. The rivet nut 24a described above is inserted into the through hole 26a and crimped so that the outer periphery of the rivet nut 24a swells, and the washer 24 and the trunk edge receiving metal fitting 26 are coupled to each other in a rotatable state. ing. That is, the washer 24 and the trunk edge receiving bracket 26 can be rotated around the axis of the bolt 11 independently of each other.

The trunk edge fitting 26 is composed of a flat plate portion 28 in which a through hole 26 a is formed, and a pair of facing wall portions (facing wall portions) 30 </ b> A and 30 </ b> B erected from the plate portion 28. ing. The pair of wall portions 30A and 30B extend in a direction away from the concrete outer wall 18 along the X-axis direction. The plate portion 28 has a rectangular flat plate shape that extends in the Z-axis direction and is narrower than the handle plate portion 24b of the washer 24 described above, and the pair of wall portions 30A and 30B are formed on the opposing long sides of the plate portion 28. It is erected across. A plurality of U-shaped notch pairs 32A and 32B are formed at the tops of the pair of wall portions 30A and 30B. A plurality of notches pairs 32A, 32B are opposed in the Y-axis direction, the wall portion 30A, are arranged at equal intervals with a pitch D ₁ to 30B. A step portion (return portion) 33 is formed in each notch of the notch pair 32A, 32B.

  By rotating the washer 24, the channel 14 slides the channel 14 in the axial direction of the bolt 11 to adjust the unevenness of the trunk edge 16 attached to the channel 14 to the concrete outer wall 18 (that is, in the X-axis direction). Position adjustment). Here, the washer 24 of the channel 14 and the body edge receiving bracket 26 employed in the exterior material fixture 10A can be independently rotated around the axis of the bolt 11 as described above, and in the case of uneven adjustment. In addition, since the extending direction of the trunk edge receiving metal fitting 26 is maintained, the unevenness adjustment is facilitated. Further, by holding and rotating the handle panel portion 24b having a width wider than that of the trunk edge receiving bracket 26 in a state in which the rotation of the trunk edge receiving bracket 26 is suppressed, only the washer 24 of the channel 14 can be easily rotated. Therefore, the use of the handle panel 24b makes it easier to adjust the unevenness of the trunk edge 16.

The trunk edge 16 is a long vertical trunk edge extending in the Y-axis direction. The trunk edge 16 is hooked to the building frame or its concrete outer wall 18 by a chain or the like at its upper end. Further, the trunk edge 16 is produced by bending a single metal plate, and includes a mounting surface portion 34 having a surface to which the exterior material 22 is mounted, and a pair of facing surfaces erected from the mounting surface portion 34. And flange portions 36A and 36B. The exterior member 22 is attached to the attachment surface portion 34 with screws 35, and two ribs 38 are provided side by side along the extending direction (Y-axis direction) of the trunk edge 16 in order to enhance rigidity. . A pair of flanges 36A, 36B extend in a direction approaching to the concrete outer wall 18 along the X-axis direction, the flange portion 36A, the mutual distance 36B is a D ₂ The D ₂ is It is twice as long as D ₁ (see FIG. 2). The end portions of the flange portions 36A and 36B are folded inward to form claw portions 40A and 40B.

  Next, a procedure for attaching the exterior material 22 to the concrete outer wall 18 using the exterior material attachment 10A according to the first embodiment will be described.

  In order to attach the exterior material 22 to the concrete outer wall 18, first, the hole-in anchor 11 </ b> A is driven into the concrete outer wall 18 and embedded. Next, the bolt 11 is screwed into the hole-in anchor 11 </ b> A, and the bolt 11 is fixed to the concrete outer wall 18. Then, the heat insulating material fixing plate 23 and the reinforcing member 13 are sequentially attached to the bolt 11.

  Next, the heat insulating material 20 with a predetermined cut is inserted so as to surround the base of the bolt 11 and the reinforcing member 13. Thereafter, the position of the heat insulating material fixing plate 23 previously attached is adjusted to press the heat insulating material 20 against the concrete outer wall 18. Thus, after the fixing of the heat insulating material 20 is completed, the channel 14 is attached to the free end 11b of the bolt 11. The body edge 16 is attached to the body edge receiving bracket 26 of the channel 14, and the exterior material 22 is screwed to the attachment surface portion 34 of the body edge 16 to complete the attachment of the exterior material 22 to the concrete outer wall 18.

  As described above, the reinforcing member 13 is attached to the bolt 11 in the exterior material fixture 10A according to the first embodiment. In the reinforcing member 13, the female screw portion 13 a is screwed into the male screw portion 12 of the bolt 11, and the bolt 11 and the reinforcing member 13 are firmly fixed in the axial direction (X direction) of the bolt 11. . And the displacement with respect to the concrete outer wall 18 of this internal thread part 13a is suppressed by the fixing | fixed part 13b fixed to the concrete outer wall 18. FIG. Therefore, the reinforcing member 13 is formed between the bolt 11 and the reinforcing member 13 with respect to the axial direction (X direction) of the bolt 11 as compared with a conventional reinforcing member provided with a pipe portion (mounting portion) for simply passing the bolt. The bond is strengthened. Therefore, even when a tensile force is applied to the exterior material fixture 10 </ b> A in the axial direction of the bolt 11 due to the wind blown on the exterior material 22, a situation in which the exterior material 22 is detached from the concrete outer wall 18 is suppressed.

When the channel 14 and the barrel edge 16 are coupled, the flange portion 36A of the surface of the plate portion 28 of the channel 14 where the wall portions 30A and 30B extend and the surface of the attachment surface portion 34 of the trunk edge 16 are combined. The channel 14 and the trunk edge 16 are brought into contact with each other in a state where the surface side from which 36B extends faces each other. Since the plate portion 28 of the channel 14 extends in the Z-axis direction and the mounting surface portion 34 of the trunk edge 16 extends in the Y-axis direction, the wall portions 30A and 30B of the channel 14 and the flange portion 36A of the trunk edge 16 are provided. , 36B are in contact with each other. At this time, by aligning the positions of the notch pairs 32A and 32B formed on the walls 30A and 30B with the positions of the flange parts 36A and 36B, the flange parts 36A and 36B are elastically deformed to cause the notch pairs 32A and 32A. It fits in 32B and the channel 14 and the trunk edge 16 are couple | bonded. Incidentally, the flange portion 36A, the distance D ₂ of 36B is notched pair 32A, since it is twice the pitch D ₁ of the 32B, 1 pair of notches pairs 32A, across the 32B, a pair of flanges 36A, 36B fits into two pairs of notches 32A and 32B.

  Here, since the return portion 33 is formed in the notch pair 32A, 32B and the claw portions 40A, 40B are formed in the flange portions 36A, 36B, the flange portions 36A, 36B are elastically deformed. Even when the claw portions 40A and 40B are locked to the return portion 33 and an external force in a direction in which the channel 14 and the trunk edge 16 are separated is applied to the channel 14 and the trunk edge 16, the channel 14 and the trunk edge 16 are not easily detached. ing. Therefore, the situation where the trunk edge 16 falls off from the channel 14 is avoided.

  As described above, when the flange portions 36A and 36B are fitted into the notch pairs 32A and 32B and the channel 14 and the trunk edge 16 are coupled to each other, the trunk edge 16 is extended even after the coupling with the channel 14. It is slidable in the current direction (Y-axis direction). Therefore, with respect to vibration in the Y-axis direction in which the trunk edge 16 extends, the flange portions 36A and 36B of the trunk edge 16 slide along the notch pairs 32A and 32B of the channel 14 to absorb the vibration. be able to. Further, with respect to the vibration in the Z-axis direction orthogonal to the extending direction of the trunk edge 16, the trunk edge receiving bracket 26 attached to the trunk edge 16 rotates around the axis of the bolt 11 to absorb the vibration. can do.

  That is, in this exterior material fixture 10A, the trunk edge 16 and the channel 14 are coupled in a state in which the trunk edge 16 and the channel 14 can slide in the extending direction of the trunk edge 16 (Y-axis direction). The vibration in the present direction can be absorbed. Therefore, in the outer heat insulation in which the exterior material fixture 10A is adopted, regarding the vibration in the extending direction of the trunk edge 16, vibration transmission from the building housing to the exterior material is suppressed, and high earthquake resistance is realized. . Further, the exterior material fixture 10A can absorb vibration in the Z-axis direction orthogonal to the extending direction of the trunk edge 16 by employing the channel 14 that is rotatable around the bolt 11, so that vibration in this direction is also possible. In addition, the vibration transmission from the building frame to the exterior material is suppressed, and high earthquake resistance is realized.

In the above-described embodiment, the pair of fixing portions 13b of the reinforcing member 13 branches into two hands in the horizontal plane, but as shown in FIG. 3, the two hands in the plane stretched by the X axis and the Y axis. You may change suitably to the reinforcement member 13 which has the fixing | fixed part 13b branched to.

  As shown in FIGS. 4 and 5, the exterior material fixture 10 </ b> B is reinforced by the fact that the bolt 11 is composed of two bolts (first support shaft) 11 </ b> P and a bolt (second support shaft) 11 </ b> Q. Unlike the exterior material fixture 10A according to the first embodiment described above, the nut 45 is attached to the bolt 11 instead of the member 13, and the other portions are the same as or similar to the exterior material fixture 10A. ing.

  Each of the bolt 11P and the bolt 11Q is formed with a male screw portion (first male screw portion) 12P and a male screw portion (second male screw portion) 12Q over the entire length thereof. And the volt | bolt 11Q is coaxially attached to the free end side of the volt | bolt 11P. The bolt 11P and the bolt 11Q are connected by a nut 45 having a female screw portion.

Here, the diameter _{D P} of the bolt 11P is larger than the diameter _{D Q} of the bolt 11Q. Therefore, among the female screw portion of the nut 45, a female screw portion of the center than the bolt 11P side (first female screw portion) 45a is made substantially the same diameter as the diameter D _P of the bolt 11P, whereas, the center The female screw portion (second female screw portion) 45b on the bolt 11Q side has substantially the same diameter as the diameter _{DQ of the} bolt 11Q.

  Next, the procedure for attaching the exterior material 22 to the concrete outer wall 18 using the exterior material fixture 10B according to the second embodiment will be described.

  In order to attach the exterior material 22 to the concrete outer wall 18, first, the hole-in anchor 11 </ b> A is driven into the concrete outer wall 18 and embedded. Next, the bolt 11P is screwed into the hole-in anchor 11A, and the bolt 11P is fixed to the concrete outer wall 18. And while insulating the heat insulating material 20 against the concrete outer wall 18 so that the volt | bolt 11P may stab, the heat insulating material fixing plate 23 is attached to the volt | bolt 11P. Thereafter, the nut 45 is attached to the free end of the bolt 11 </ b> P, and the bolt 11 </ b> Q is attached to the nut 45. The subsequent procedure is the same process as in the first embodiment in which the channel 14 and the trunk edge 16 are attached to the bolt 11.

As described above, in the exterior material fixture 10B according to the second embodiment, the diameter of the bolt 11P is larger than that of the bolt 11Q. Thus, when the diameter of the bolt 11P fixed to the concrete outer wall 18 is larger than the bolt 11Q to which the channel 14 is attached, the contact area with the concrete outer wall 18 can be increased. Therefore, in this exterior material fixture 10B, the exterior material 22 can be more firmly fixed as compared with the case where the bolt 11Q to which the channel 14 is attached is directly fixed to the concrete outer wall 18.
(Third embodiment)

  Next, an exterior material fixture 10C according to a third embodiment of the present invention will be described. FIG. 6 is a schematic perspective view showing an exterior material fixture 10C according to the third embodiment of the present invention. FIG. 7 is a cross-sectional view of the exterior material fixture 10C shown in FIG. 6 taken along the line VII-VII.

  As shown in FIGS. 6 and 7, the exterior material fixture 10 </ b> C according to the third embodiment includes a bolt 11, a bar (trunk edge receiving member) 114, a trunk edge 116, and a washer similar to those of the first embodiment. 117.

  The washer 117 includes a cylindrical rivet nut 117a in which an internal thread portion 125 corresponding to the external thread portion 12 of the bolt 11 is formed on the inner peripheral surface, and a rectangular flat plate-shaped handle formed on the outer peripheral edge of the rivet nut 117a. It is comprised with the board part 117b. Here, the rivet nut 117a has a female threaded portion 125 on its inner peripheral surface engaged with the male threaded portion 12 of the bolt 11, and the rivet nut 117a rotates relative to the bolt 11, The rivet nut 117a slides in the axial direction (X-axis direction) of the bolt 11. The rivet nut 117a is fixed to the handle panel 117b extending in the axial direction of the bolt 11 by caulking, and the rivet nut 117a is integrated when the handle panel 117b rotates about the axis of the bolt 11. To turn. The handle panel 117b is formed with two ribs (projections) 117c, which will be described later, projecting toward the plate 126 of the bar 114.

  The bar 114 is formed by bending and forming a single thin metal plate having sufficient flexibility, and includes a flat plate portion 126 and a pair of facing walls erected from the plate portion 126. Part (facing wall part) 130A, 130B. The pair of wall portions 130A and 130B extend in a direction away from the concrete outer wall 18 along the X-axis direction. In addition, claw portions 131A and 131B that are bent in the direction facing each other are formed at the tops of the pair of wall portions 130A and 130B. The plate portion 126 has a rectangular flat plate shape that extends in the Z-axis direction and is narrower than the handle plate portion 117b of the washer 117 described above, and the pair of wall portions 130A and 130B are formed on the long sides facing the plate portion 126. It is erected across.

  In the center of the plate portion 126 of the bar 114, an oval slit (long hole) 126a is provided that extends in the facing direction of the wall portions 130A and 130B and through which the rivet nut 117a passes. The width of the slit 126a is slightly larger than the outer diameter of the rivet nut 117a and smaller than the outer diameter of the large-diameter stopper portion 117d at the tip of the rivet nut. Further, a holding fitting 127 for closing the slit 126a is disposed on the side of the body edge 116 of the slit 126a. The holding metal 127 is provided with a through hole 127a having a diameter slightly larger than the outer diameter of the rivet nut 117a and smaller than the outer diameter of the stopper portion 117d, and the rivet nut 117a passes through the through hole 127a. . That is, the bar 114 and the holding fitting 127 are prevented from falling off from the rivet nut 117a by the stopper portion 117d, and rotate around the axis of the bolt 11 by sliding on the outer periphery of the rivet nut 117a. Can do. Further, the handle panel 117b fixed to the rivet nut 117a can be rotated around the axis of the bolt 11 together with the rivet nut 117a, and the handle panel 117b and the bar 114 are independent of each other around the axis of the bolt 11. To turn.

  By rotating the washer 117, the bar 114 can be slid in the axial direction of the bolt 11, and the unevenness of the trunk edge 116 attached to the bar 114 to the concrete outer wall 18 can be adjusted. Here, the washer 117 and the bar 114 employed in the exterior material fixture 10C can be independently rotated around the axis of the bolt 11 as described above, and the extension of the bar 114 is also performed during unevenness adjustment. Since the direction is maintained, it is easy to adjust the unevenness. In addition, the handle panel 117b is adopted because only the washer 117 can be easily rotated by gripping and rotating the handle panel 117b wider than the bar 114 while the rotation of the bar 114 is suppressed. This makes it easier to adjust the unevenness of the trunk edge 116.

The trunk edge 116 is a long vertical trunk edge extending in the Y-axis direction. The trunk edge 116 is hooked to the building frame or its concrete outer wall 18 with a chain or the like at its upper end. The trunk edge 116 is formed by bending a single metal plate, and includes a mounting surface portion 134 having a surface to which the exterior material 22 is mounted and a pair of facing surfaces erected from the mounting surface portion 134. And flange portions 136A and 136B. That is, the body edge 116 has a structure in which the attachment surface portion 134 is bridged between the flange portions 136A and 136B. The exterior member 22 is attached to the attachment surface portion 134 with screws 135, and the pair of flange portions 136A and 136B extend in a direction approaching the concrete outer wall 18 along the X-axis direction. Further, a plurality of notches 138 are formed at the same position on both the flange portions 136A and 136B at the tops of the pair of flange portions 136A and 136B. The plurality of notches 138 are opposed to each other in the Z-axis direction, and are arranged at equal intervals in the flange portions 136A and 136B. Each notch 138 has a stepped portion (return portion) 139. In the present embodiment, the claw portions 131A and 131B of the bar 114 are fitted into the two notches (notch pairs) 138 and 138 on both sides of the three notches 138 arranged side by side. Then, the claw portion 131A, _{(D 3} in FIG. 7) the maximum width of the notch pairs 138, 138 131B is fitted is larger than the claw portion 131A, the distance of 131B _{(D 4} in FIG. 7).

  Next, a procedure for attaching the exterior material 22 to the concrete outer wall 18 using the exterior material attachment 10C according to the third embodiment will be described.

  In order to attach the exterior material 22 to the concrete outer wall 18, first, the hole-in anchor 11 </ b> A is driven into the concrete outer wall 18 and embedded. Next, the bolt 11 is screwed into the hole-in anchor 11 </ b> A, and the bolt 11 is fixed to the concrete outer wall 18. Then, the heat insulating material fixing plate 23 and the reinforcing member 13 are sequentially attached to the bolt 11.

  Next, the heat insulating material 20 with a predetermined cut is inserted so as to surround the base of the bolt 11 and the reinforcing member 13. Thereafter, the position of the heat insulating material fixing plate 23 previously attached is adjusted to press the heat insulating material 20 against the concrete outer wall 18. In this manner, after the heat insulating material 20 is fixed, the washer 117, the bar 114, and the trunk edge 116 are attached to the free end 11b of the bolt 11. The body edge 16 is attached to the body edge bracket 26 on the attachment surface part 134 of the body edge 16, and the exterior material 22 is screwed to the attachment surface part 34 of the body edge 16 to attach the exterior material 22 to the concrete outer wall 18. Is completed.

  As described above, the reinforcing member 13 is attached to the bolt 11 in the exterior material fixture 10C according to the third embodiment. In the reinforcing member 13, the female screw portion 13 a is screwed into the male screw portion 12 of the bolt 11, and the bolt 11 and the reinforcing member 13 are firmly fixed in the axial direction (X direction) of the bolt 11. . And the displacement with respect to the concrete outer wall 18 of this internal thread part 13a is suppressed by the fixing | fixed part 13b fixed to the concrete outer wall 18. FIG. Therefore, the reinforcing member 13 is formed between the bolt 11 and the reinforcing member 13 with respect to the axial direction (X direction) of the bolt 11 as compared with a conventional reinforcing member provided with a pipe portion (mounting portion) for simply passing the bolt. The bond is strengthened. Therefore, even when a tensile force is applied to the exterior material fixture 10 </ b> C in the axial direction of the bolt 11 due to the wind blown on the exterior material 22, a situation where the exterior material 22 is detached from the concrete outer wall 18 is suppressed.

  When the bar 114 and the barrel edge 116 are joined, the flange portion 136A of the surface of the plate portion 126 of the bar 114 where the wall portions 130A and 130B extend and the surface of the mounting surface portion 134 of the barrel edge 116 are combined. The bar 114 and the trunk edge 116 are brought close to each other in a state where the surface side from which 136B extends faces each other. Since the plate portion 126 of the bar 114 extends in the Z-axis direction and the mounting surface portion 134 of the barrel edge 116 extends in the Y-axis direction, the wall portions 130A and 130B of the bar 114 and the flange portion 136A of the barrel edge 116 are provided. , 136B come into contact. At this time, by aligning the positions of the notches 38 formed in the flange portions 136A and 136B with the positions of the claw portions 131A and 131B of the wall portions 130A and 130B, the plate portion 126 of the bar 114 is elastically deformed, and the claw The portions 131A and 131B are fitted into the notches 138, and the bar 114 and the trunk edge 116 are joined. When the flange portions 136A and 136B and the notch 138 are aligned, the position can be easily corrected by sliding the bar 114 in the slit extending direction (Y-axis direction).

At the time of coupling between the bar 114 and the furring strip 116, a maximum distance _{D 3} of the notch 138 described above, the claw portion 131A, since wider than the distance _{D 4} of 131B, bent plate portion 126 of the bar 114 is Thereby, the space | interval of nail | claw part 131A, 131B spreads. And claw part 131A, 131B is latched in the return part 139 which is substantially the same as the separation distance of claw part 131A, 131B. By adopting such a return portion 139, even when an external force in a direction in which the bar 114 and the trunk edge 116 are separated is applied to the bar 114 and the trunk edge 116, the bar 114 and the trunk edge 116 are not easily detached. Thereby, the situation where the trunk edge 116 falls off from the bar 114 is avoided. In addition, when the bar 114 and the trunk edge 116 are coupled, the trunk edge 116 does not need to bend, and thus can be thick enough to support the exterior material 22 firmly. Note that a reinforcing member such as a buckle may be attached to the attachment surface portion 134 of the trunk edge 116 in order to further improve the support strength of the exterior member 22.

  As described above, a part of the rib 117c of the washer 117 is in contact with the plate portion 126 of the portion where the wall portions 130A and 130B of the bar 114 are erected. For this reason, the plate portion 126 of the bar 114 is less likely to be elastically deformed so as to protrude toward the body edge 116, and thus the claw portions 131 </ b> A and 131 </ b> B that are locked to the return portion 139 are less likely to come off. Yes.

  The operation of fitting the wall portions 130A and 130B into the notch 138 is very easy as compared with a conventional exterior material fixture that uses a screw or the like to join the trunk edge receiver and the trunk edge. When the fixture 10C is used, the workability of the base assembling work is greatly improved. Even after the bar 114 and the trunk edge 116 are joined, the trunk edge 116 is slidable in the extending direction of the bar 114 (Z-axis direction). Therefore, the trunk edge 116 can absorb the vibration in the Z-axis direction by sliding the notch 138 along the wall portions 130A and 130B of the bar 114. Further, the vibration in the Y-axis direction, which is the extending direction of the trunk edge 116, can be absorbed by sliding the bolt 11 in the slit 26a.

That is, in this exterior material fixture 10C, the bar 114 is coupled to the trunk edge 116 having the attachment surface portion 134 to which the exterior material 22 is attached, at the wall portions 130A and 130B. The coupling between the bar 114 and the trunk edge 116 is caused by bending the plate portion 126 of the bar 114 having flexibility, and the separation distance D ₄ between the claw portions 131A and 131B formed on the wall portions 130A and 130B of the bar 114. The claw portions 131A and 131B are fitted into the wider cutout 38, and the claw portions 131A and 131B are engaged with the return portion 139 of the cutout 138. As described above, since the coupling between the bar 114 and the trunk edge 116 is performed by fitting, it can be easily performed as compared with the conventional exterior material fixture that couples the trunk edge receiving member and the trunk edge using screws or the like. . Also, the rib 117c of the washer 117 contacts the plate portion 126 where the wall portions 130A and 130B are erected. Therefore, the bending of the plate portion 126 of the bar 114 is suppressed, and the claw portions 131A and 131B of the bar 114 and the notch 138 of the trunk edge 116 are hardly detached. Therefore, the bar 114 and the trunk edge 116 are firmly coupled.

As shown in FIG. 8, the washer 17 is configured so that the rib 117 c is parallel to the extending direction (Z-axis direction) of the bar 114 when the bar 114 and the trunk edge 116 are coupled. This is a state in which the washer 117 described above is rotated 90 degrees around the bolt 11. FIG. 8 is a schematic perspective view showing a state of the washer 117 when the bar 114 and the trunk edge 116 are coupled. Since the interval between the two ribs 117c is narrower than the interval between the wall portions 30A and 30B of the bar 114, when the washer 117 is in the position shown in FIG. 8, the rib 117c of the washer 117 is the wall portions 130A and 130B. It contacts the inner plate part 126. Therefore, when the bar 114 and the barrel edge 116 are joined, when the flange portions 136A and 136B of the barrel edge 116 come into contact with the wall portions 130A and 130B of the bar 114, the plate portion 126 on which the wall portions 130A and 130B stand up. The long side end portion bends in the direction of the washer 117 with a slight force, and the distance between the claw portions 131A and 131B increases. That is, by adjusting the angular position of the washer 117 with respect to the axis of the bolt 11, the bar 114 and the trunk edge 116 can be easily combined.
(Fourth embodiment)

  Next, an exterior material fixture 10D according to a fourth embodiment of the present invention will be described. FIG. 9 is a schematic perspective view showing an exterior material fixture 10D according to the fourth embodiment of the present invention. FIG. 10 is a sectional view taken along line XX of the exterior material fixture 10D shown in FIG.

  As shown in FIGS. 9 and 10, the exterior material fixture 10 </ b> D is such that the bolt 11 is configured by the same bolt 11 </ b> P and bolt 11 </ b> Q as in the second embodiment, and the nut 45 is a bolt instead of the reinforcing member 13. 11 is the same as or similar to the exterior material fixture 10C in the other parts, unlike the exterior material fixture 10C according to the third embodiment described above.

  Also in the exterior material fixture 10D according to the fourth embodiment, the diameter of the bolt 11P is larger than that of the bolt 11Q, like the exterior material fixture 10B according to the second embodiment. Thus, when the diameter of the bolt 11P fixed to the concrete outer wall 18 is larger than the bolt 11Q to which the washer 117, the bar 114, and the trunk edge 116 are attached, the contact area with the concrete outer wall 18 is increased. Therefore, the exterior material 22 can be firmly fixed as in the second embodiment.

  The present invention is not limited to the above embodiment, and various modifications are possible. For example, although the example mentioned above was an example mainly about an outer heat insulation, it cannot be overemphasized that it can apply easily also to the external insulation used in a wooden house. Further, the male screw portion of the bolt does not necessarily have to be formed over the entire length thereof, and can be appropriately formed partially such as a portion in contact with the end portion or the reinforcing member. Furthermore, in the above-described example, only the reinforcing member having a pair of fixing portions is shown, but it can be appropriately changed to a reinforcing member having one fixing portion or a reinforcing member having three or more fixing portions.
