Description

  The present invention relates to an exterior material mounting bracket used to attach an exterior material such as a ceramic siding material to a wall base of a building.

  Conventionally, as an exterior material mounting bracket for fixing an exterior material attached along the vertical direction of a building wall to the building wall, for example, the one described in Patent Document 1 is known. The exterior material mounting bracket includes a fixed plate, a horizontal piece, an upper support piece, and a lower support piece.

  Here, the fixing plate is attached and fixed to the wall base of the building. Further, the horizontal piece is provided so as to protrude forward in the center of the fixed plate. The upper support piece protrudes upward from the front end of the horizontal piece, and engages and supports the lower end portion of the exterior material attached on the upper side. The lower support piece projects downward from the front end of the horizontal piece, and engages and supports the upper end portion of the exterior material attached to the lower side.

  Specifically, the exterior material is formed by providing an engaging recess that opens downward at the lower end and an engaging convex portion that protrudes upward at the upper end. A rear projection is provided behind the engagement recess. Then, the upper support piece of the exterior material mounting bracket is engaged with and supported by the rear convex portion of the lower end of the upper exterior material, and the lower support piece of the exterior material mounting bracket is engaged with the upper end of the lower exterior material. It is supported by engaging with the part.

  Furthermore, a receiving piece is provided on the exterior material mounting bracket. This receiving piece is positioned at least partially above the horizontal piece and abuts against the lower end of the exterior material attached on the upper side to receive at least a part of the load. Therefore, the exterior material can be attached without applying a great load to the exterior material attached to the lower side, and damage or deformation of the exterior material can be prevented.

International Publication No. 2011/040515

  However, in the exterior material mounting bracket described in Patent Document 1, the upper support piece of the exterior material mounting bracket engages and supports the rear convex portion of the lower end of the upper exterior material with almost no gap. The lower support piece of the mounting bracket engages and supports the engagement convex portion at the upper end of the lower exterior member with almost no gap. In this case, for example, if an external force more than expected is applied in the direction of peeling the exterior material from the building due to negative pressure or the like, the movement of the rear convex part of the lower end of the exterior material is particularly near the base of the upper support piece of the exterior material mounting bracket And the movement of the front end of the engaging projection at the upper end of the exterior member is restricted near the base of the lower support piece of the exterior material mounting bracket. Then, a moment of force corresponding to the length from the front end of the rear convex portion to the vicinity of the root and from the front end of the engagement convex portion to the vicinity of the root is generated, and near the base of the rear convex portion and the engaging convex portion. Stress concentrates, and there is a possibility that the rear convex portion and the engaging convex portion may be lost depending on the use environment. Therefore, further improvement in the mounting strength of the exterior material is required. Of course, the rear and engaging protrusions must be formed thinner than the thickness of the exterior material, but to increase the thickness of the rear and engaging protrusions in order to improve strength. There is a limit.

  This invention is made | formed in view of said point, and it aims at providing the exterior material attachment metal fitting which can attach an exterior material to the wall base of a building firmly.

  Embodiments of the present invention will be described below.

  1 to 4 show an example of an embodiment of an exterior material mounting bracket 1 according to the present invention, and FIG. 5 uses this exterior material mounting bracket 1 to attach an exterior material 12 to a wall base 15 of a building. An example of the exterior material attachment structure formed in this way is shown.

  As shown in FIG. 1, the exterior material mounting bracket 1 includes a fixing plate 2, a horizontal piece 3, an upper support piece 4, a lower support piece 5, a protruding piece 6, an inward piece 7, and an outward piece 8. And is formed. The exterior material mounting bracket 1 can be obtained by appropriately cutting and bending a metal plate. The horizontal piece 3, the upper support piece 4, the lower support piece 5, the protruding piece 6, the inward piece 7, and the outward piece 8 can be formed by cutting and raising a part of the fixed plate 2.

  The fixing plate 2 constitutes the main body of the exterior material mounting bracket 1 and is fixed to the wall base 15 of the building as shown in FIG. The fixing plate 2 is provided with a fixing hole 10. As shown in FIG. 5, the fixing plate 2 can be fixed by inserting a fixing tool 16 such as a nail, a screw, or a screw into the fixing hole 10 and striking it against the wall substrate 15. A first rib 17 is provided at the upper end of the fixed plate 2. The first rib 17 is formed of an upper slope 17a and a lower slope 17b. The first rib 17 is formed to have a substantially L-shaped cross-section by bending so as to protrude forward at a boundary portion between the upper slope 17a and the lower slope 17b over substantially the entire length of the fixing plate 2 in the left-right direction. A second rib 18 having a substantially C-shaped cross section is formed at the lower end portion of the fixing plate 2 so as to protrude forward over substantially the entire length in the left-right direction. The strength of the exterior material mounting bracket 1 is increased by the first rib 17 and the second rib 18. Although a plurality of fixing holes 10 can be provided, at least one fixing hole 10 a is provided below the first rib 17 and in the vicinity above the horizontal piece 3. The fixing hole 10a is provided at substantially the center in the left-right direction of the fixing plate 2. On the both sides of the fixing hole 10a, the vertical direction from the lower slope 17b of the first rib 17 to the horizontal piece 3 is increased in order to increase the strength. A third rib 20 is formed to protrude forward. A plurality of other fixing holes 10 b are provided on the upper slope 17 a of the first rib 17. In order to further increase the strength, the fourth rib 21 is formed to protrude forward in the vertical direction from the upper end edge of the fixing plate 2 to the upper slope 17a of the first rib 17.

  The horizontal piece 3 is provided so as to protrude forward from a substantially center in the vertical direction of the fixed plate 2. Since the horizontal piece 3 is formed by cutting and raising substantially the lower half of the fixed plate 2, an opening 19 is formed in the lower portion of the fixed plate 2. A horizontal protrusion 22 is formed at the center of the horizontal piece 3. The horizontal convex part 22 protrudes upward, and the upper part is a substantially flat surface. The horizontal convex part 22 functions as a rib, and can especially increase the strength of the horizontal piece 3. As shown in FIG. 2, a U-shaped slit 23 is formed in the horizontal convex portion 22, and a receiving piece 24 is formed inside the U-shaped slit 23. The receiving piece 24 is provided with a slight inclination so that its tip is directed forward and protrudes from the upper surface of the horizontal convex portion 22. As shown in FIGS. 1 and 2, a fifth rib 25 is formed at the boundary between the fixed plate 2 and the horizontal piece 3 in order to increase the strength.

  The upper support piece 4 is provided so as to protrude upward from the front end of the horizontal piece 3 and supports the exterior member 12 attached to the upper side. The upper support piece 4 is provided continuously over substantially the entire length of the horizontal piece 3 in the left-right direction without being divided. At a position corresponding to the fixing hole 10 a of the upper support piece 4, the defect portion 11 is provided leaving at least the lower end of the upper support piece 4. For example, the defect 11 shown in FIG. 1 is provided so as not to reach the front end of the horizontal piece 3 by cutting off the tip of the upper support piece 4. More specifically, the defect portion 11 is formed by notching the tip of the upper support piece 4 in a substantially semicircular shape and attaching Rs on both sides, but is not limited to such a shape. That is, although not shown in the drawings, the defect portion 11 may be provided as a circular through hole leaving the upper end and the lower end of the upper support piece 4. The defect portion 11 is for facilitating insertion of the fixture 16 so that the upper support piece 4 does not obstruct the insertion of the fixture 16 when the fixture 16 is inserted into the fixing hole 10a. At both ends in the left-right direction of the front end of the horizontal piece 3, sixth ribs 26 are formed to protrude upward at the boundary between the horizontal piece 3 and the upper support piece 4 in order to increase the strength.

  The lower support piece 5 is provided so as to protrude downward from the front end of the horizontal piece 3 and supports the exterior material 12 attached to the lower side. The lower support piece 5 is divided into two parts, but may be provided continuously like the upper support piece 4. A protrusion 27 is provided on the rear surface near the tip of the lower support piece 5.

  The protruding piece 6 is provided to protrude forward from the left and right ends of the fixing plate 2 so as to be shorter than the protruding length of the horizontal piece 3. The protruding piece 6 can form a ventilation space 28 between the exterior member 12 and the wall base 15 as shown in FIG.

  The inward piece 7 is provided so as to extend from the front end of the protruding piece 6 substantially in parallel to the fixed plate 2 and to the side (inner side) of the fixed plate 2. In the protruding piece 6, the inwardly facing piece 7 is provided below the horizontal piece 3, and supports the lower surfaces of the left and right sides of the horizontal piece 3 at the upper edge of the inwardly facing piece 7 provided on the left and right protruding pieces 6. ing. In this way, by supporting the horizontal piece 3 with the inward pieces 7 that are substantially perpendicular to the horizontal piece 3, the horizontal piece 3 is not affected even when a load is applied to the lower side of the upper exterior member 12. It becomes difficult to sag, and rattling of the exterior material 12 can be suppressed.

  The outward piece 8 is provided so as to extend from the front end of the protruding piece 6 substantially parallel to the fixed plate 2 and to the opposite side (outside) of the fixed plate 2 side. In the protruding piece 6, the outwardly facing pieces 8 are provided alternately above and below the inwardly facing piece 7. Thus, the deformation of the protruding piece 6 can be suppressed by alternately providing the inward pieces 7 and the outward pieces 8 on the protruding piece 6.

  In particular, as shown in FIG. 1, it is preferable that the reinforcing rib 9 is formed to protrude outward from the position higher than the horizontal piece 3 to the position lower than the lower end edge of the inward piece 7 in the protruding piece 6. . When the reinforcing rib 9 is formed in this way, the deformation of the protruding piece 6 can be further suppressed.

  Next, a method of forming the exterior material attachment structure as shown in FIG. 5 by attaching the exterior material 12 to the wall base 15 of the building using the exterior material attachment metal fitting 1 will be described.

  As the exterior material 12, a rectangular material can be used. The exterior material 12 is formed by providing an engagement recess 13 that opens downward on substantially the entire length of the lower end, and an engagement protrusion 14 that protrudes upward on the substantially entire length of the upper end. A front convex portion 29 is provided in front of the engaging recess 13, and a rear convex portion 30 is provided behind the engaging recess 13. The protrusion length from the bottom surface of the engagement recess 13 is such that the front convex portion 29 is long and the rear convex portion 30 is short. A step portion 31 is provided in front of the engaging convex portion 14.

  First, after the lower exterior material 12 is attached, the exterior material 12 is moved between the lower support piece 5 and the projecting piece 6 while moving the exterior material fitting 1 downward from above the exterior material 12. The engaging convex portion 14 is inserted, and the lower support piece 5 is hooked on the engaging convex portion 14 to be engaged. In this state, the fixture 16 is fixed by inserting the fixture 16 into the fixing hole 10 of the fixing plate 2 and driving it against the wall base 15. At this time, the protrusion 27 of the lower support piece 5 abuts against or bites into the front surface 14a of the engagement convex portion 14, thereby suppressing rattling of the exterior material 12.

  Further, a gap is formed between the vicinity of the upper end portion of the front surface 14 a of the engaging convex portion 14 and the lower support piece 5. As a result, even when an external force is applied to the exterior material 12, the movement of the vicinity of the base of the engaging convex portion 14 is restricted near the tip of the lower support piece 5 and the external force is received, and the upper end portion of the exterior material 12 is supported. The moment of force generated in the engaging convex portion 14 that is a portion can be made as small as possible. For this reason, the engagement convex portion 14 of the exterior material 12 is not easily lost.

  When the fixture 16 is inserted into the upper fixing hole 10b, the upper support piece 4 is unlikely to obstruct the insertion of the fixture 16. For this reason, it seems that only the upper fixing hole 10b may be fixed, but since the distance between the horizontal piece 3 on which the load of the exterior material 12 is applied and the upper fixing hole 10b is long, the exterior material mounting bracket 1 It is difficult to increase the mounting strength. Therefore, it is desirable to insert the fixture 16 into the lower fixing hole 10a. In this case, since the distance between the horizontal piece 3 and the lower fixing hole 10a is shortened and close to each other, the mounting strength of the exterior material mounting bracket 1 can be sufficiently increased. However, when the fixture 16 is inserted into the lower fixing hole 10 a, the upper support piece 4 can be an obstacle to insertion of the fixture 16. Therefore, by providing the upper support piece 4 with the defect portion 11, the fixture 16 can be easily inserted in the horizontal direction. Moreover, as shown in FIG. 5, the mounting angle of the fixing member 16 inserted into each of the upper fixing hole 10 b and the lower fixing hole 10 a is different, so that the mounting strength of the exterior member 12 to the wall base 15 is further increased. It is something that can be done.

  Next, the upper exterior material 12 is moved downward from above the exterior material mounting bracket 1, and the rear convex portion 30 is moved upward while the front convex portion 29 is disposed in front of the upper support piece 4 and the lower support piece 5. It inserts between the support piece 4 and the protrusion piece 6, and inserts the upper support piece 4 in the engagement recess 13 and engages it. Thereby, the lower surface of the front convex portion 29 of the upper exterior material 12 is close to or in contact with the upper surface of the step portion 31 of the lower exterior material 12, and the entire exterior material mounting bracket 1 is obscured by the front convex portion 29. It is.

  Further, a gap is formed between the vicinity of the lower end portion of the rear surface 13 a of the engagement recess 13 and the upper support piece 4. As a result, even if an external force is applied to the exterior member 12, the movement of the vicinity of the base of the rear projection 30 near the tip of the upper support piece 4 is restricted and the external force is received, and the support portion of the lower end portion of the exterior member 12 is received. The moment of force generated in the rear convex portion 30 can be made as small as possible. Therefore, the rear projection 30 of the exterior material 12 is particularly difficult to be lost.

  Here, if the horizontal piece 3 is supported by the inward piece 7 that is substantially perpendicular to the horizontal piece 3, the horizontal piece 3 is not affected even if a load is applied to the lower side of the upper exterior member 12. It becomes difficult to sag, and rattling of the exterior material 12 can be suppressed. Further, if the inwardly facing pieces 7 and the outwardly facing pieces 8 are alternately provided on the projecting pieces 6, deformation of the projecting pieces 6 can be suppressed. Therefore, the exterior material 12 can be firmly attached to the wall base 15 of the building.

  Further, since the upper support piece 4 is continuously provided without being divided in substantially the entire length of the horizontal piece 3, a support range for supporting the exterior material 12 is widened. 15 can be firmly attached.

  Here, conventionally, as shown in FIG. 6A, the upper support piece 4 of the exterior material mounting bracket 1 is engaged with and supported by the rear convex portion 30 of the lower end of the upper exterior material 12 with almost no gap. ing. In this case, for example, when an external force more than expected is applied in the direction in which the exterior member 12 is peeled off from the building by negative pressure or the like, the movement of the tip of the rear projection 30 at the lower end of the exterior member 12 is particularly supported on the exterior material mounting bracket 1. It is regulated near the root of the piece 4. Then, a moment of force corresponding to the length from the tip of the rear convex portion 30 to the vicinity of the root is generated, stress concentrates near the root of the rear convex portion 30, and the rear convex portion 30 is lost depending on the use environment. There is a risk. Therefore, in the present invention, as shown in FIG. 6B, the tip of the upper support piece 4 is brought into contact with the vicinity of the root of the rear surface 13a in the engagement recess 13 (that is, the front surface of the rear convex portion 30, the same applies hereinafter). In addition, a gap is formed between the upper support piece 4 and the vicinity of the lower end portion of the rear surface 13a in the engagement recess 13 by making the upper support piece 4 and the rear surface 13a in the engagement recess 13 non-parallel. To do. As a result, even if an external force is applied to the exterior member 12, the movement of the vicinity of the base of the rear projection 30 near the tip of the upper support piece 4 is restricted and the external force is received, and the support portion of the lower end portion of the exterior member 12 is received. The moment of force generated in the rear convex portion 30 can be made as small as possible. For this reason, the rear projection 30 of the exterior material 12 is particularly difficult to be lost, so that the exterior material 12 is not easily peeled off, and the exterior material 12 can be firmly attached to the wall base 15 of the building.

  Further, conventionally, as shown in FIG. 6A, the lower support piece 5 of the exterior material mounting bracket 1 is engaged with and supported by the engagement convex portion 14 at the upper end of the lower exterior material 12 with almost no gap. doing. In this case, for example, when an external force more than expected is applied in the direction in which the exterior member 12 is peeled off from the building due to negative pressure or the like, the movement of the front end of the engaging convex portion 14 at the upper end of the exterior member 12 is It is regulated near the base of the support piece 5. Then, a moment of force corresponding to the length from the tip of the engaging convex portion 14 to the vicinity of the root is generated, and stress concentrates near the base of the engaging convex portion 14, and depending on the use environment, the engaging convex portion 14 may be lost. Therefore, in the present invention, as shown in FIG. 6B, the tip of the lower support piece 5 is brought into contact with the vicinity of the base of the front surface 14a of the engagement convex portion 14, and the lower support piece 5 and the engagement convex portion 14 are contacted. By making the front surface 14 a non-parallel, a gap is formed between the lower support piece 5 and the front surface 14 a of the engaging convex portion 14. As a result, even when an external force is applied to the exterior material 12, the movement of the vicinity of the base of the engaging convex portion 14 is restricted near the tip of the lower support piece 5 and the external force is received, and the upper end portion of the exterior material 12 is supported. The moment of force generated in the engaging convex portion 14 that is a portion can be made as small as possible. For this reason, since the engagement projections 14 of the exterior material 12 are particularly difficult to be lost, the exterior material 12 is difficult to peel off, and the exterior material 12 can be firmly attached to the wall base 15 of the building.
