Description

  The present invention relates to an outer wall material mounting bracket for fixing an outer wall material to a wall base, and more particularly to an outer wall material mounting bracket used for fixing a laterally stretched outer wall material.

  The laterally stretched outer wall material has a joining structure for joining the outer wall materials to the upper and lower sides extending in the horizontal direction. Each of these joining structures is a structure having an insertion piece projecting upward or downward at a portion of the outer wall material on the wall base material side. In the upper side joining structure, a cutout step portion is provided on the outer side of the insertion piece. In the lower side joining structure, a cutout step of the upper side joining structure is provided on the outer side of the insertion piece. The covering piece which fits in the part is suspended.

  The outer wall material mounting bracket has a structure that is locked to the joint structure between the upper side and the lower side. In other words, it has a fastening plate part that is attached to the fixed part of the wall base and a horizontal piece that protrudes forward from the fastening plate part. It has a structure having a hanging piece to be locked and an upright piece that stands upward and locks the insertion piece on the lower side of the outer wall material. The hanging piece of the outer wall material mounting bracket is locked to the insertion piece on the upper side of the outer wall material fixed to the lower side, and this outer wall material mounting bracket is fixed to the wall base, and then the standing piece of the outer wall material mounting bracket is used. The outer wall material is fixed by engaging the insertion piece on the lower side of the outer wall material fixed on the upper side.

  In order to strengthen this fixed state, for example, as disclosed in Patent Document 1 below, the upright piece is bent upward at an acute angle from the position of the front end edge of the horizontal piece, and the outer wall material is elastically repelled. It is proposed that the elastic bent piece is pushed back toward the wall base.

  When the elastic bent piece portion is thus provided, the outer wall material can be firmly fixed by the pressing action of the elastic bent piece portion.

Utility Model Registration No. 25007028

  However, since the outer wall material is a so-called ceramic industry that uses fiber reinforced cement or the like as a material, it is heavy. Although the elastic bent piece portion presses the outer wall material in the direction of the wall base, the elastic bent piece portion is formed by bending upward at an acute angle from the horizontal piece, so that a concentrated load is applied to the base portion. However, the corner portion to which the concentrated load is applied has no support as disclosed in FIG.

  In other words, the elastic action of the elastic bending piece part mainly depends on the constituent material, and the corner part is apt to be brittle due to secular change. There is a risk of flying.

  Therefore, the main object of the present invention is to make it possible to firmly fix the outer wall material and to enhance the durability.

  Means therefor include a horizontal piece projecting forward from the fastening plate portion attached to the fixed surface, and a hanging piece that hangs downward and locks the upper end insertion piece of the outer wall material at the tip of the horizontal piece, An outer wall material mounting bracket having an upright piece that stands up and locks a lower end insertion piece of the outer wall material, wherein the hanging piece or the base piece of at least one of the hanging piece or the upstanding piece can be elastically displaced. A bent convex portion for supporting the upright piece is formed, and when the bent convex portion is formed on the hanging piece, the horizontal piece is formed above the horizontal piece, and when formed on the upright piece, the horizontal piece. It is an outer wall material attachment metal fitting which protrudes below rather.

  In the outer wall material mounting bracket with this structure, the vertical and standing pieces can be elastically displaced so that the bent protrusions formed on the base of one or both of the hanging pieces and the standing pieces are not subjected to concentrated load. Support elastically. The bent protrusion protrudes in the opposite direction to the extending direction of the piece on which it is formed so that it can be locked with the insertion piece with which the piece is locked.

  According to the present invention, the hanging piece and the upright piece that are supported so as to be elastically deformable by the bent convex portion lock the insertion piece of the outer wall material, so that the outer wall material can be strongly fixed by the action of the elastic force, Since the bent convex portion has a structure in which a concentrated load is not applied to one place unlike a conventional metal fitting, durability can be improved.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view of an outer wall material attachment fitting 11 (hereinafter referred to as “metal fitting”), which fixes the outer wall material 21 to the wall base 31 as shown in FIG. The metal fitting 11 shown in this example is a metal fitting 11 having a structure in which an air passage 41 is formed between the wall base 31 and the outer wall material 21.

First, the schematic structure of the outer wall material 21 will be described.
The outer wall material 21 is a plate material having a predetermined thickness, and has an upper side extending in the left-right direction at the upper end and a lower side extending in parallel with the upper side at the lower end, and joining structure portions 22 and 23 for joining the outer wall materials 21 to the upper side and the lower side. have. The joint structure portion 22 on the upper side is a portion that locks the metal fitting 11 and joins the outer wall member 21 connected to the upper side via the metal fitting 11. The joint structure 23 on the lower side is a part that is fixed to the joint structure 22 on the upper side of the outer wall member 21 fixed on the lower side via the metal fitting 11.

  The joining structure portion 22 on the upper side has an upper end insertion piece 24 having a predetermined thickness protruding upward at a portion of the thickness of the outer wall material 21 on the wall base 31 side. A notch step portion 25 is formed on the outer surface side of the upper end insertion piece 24.

  The lower-side joining structure portion 23 has a lower end insertion piece 26 having a predetermined thickness protruding downward at a portion of the outer wall material 21 on the wall base material 31 side. A locking space 27 that enters upward is formed on the outer surface side of the lower end insertion piece 26, and extends downward from the lower end of the lower end insertion piece 26 on the outer surface side of the locking space 27. A covering piece 28 that fits into the notch step portion 25 in the joining structure 22 is suspended. A portion extending from the lower end of the lower end insertion piece 26 to the upper end portion of the locking space 27 has an inclined surface 26 a inclined forward.

  Next, the structure of the metal fitting 11 will be described.

  As shown in FIGS. 1 to 4, the metal fitting 11 is made of a single metal plate, and is attached to the front side on both the left and right sides of the fastening plate portion 12, and the fastening plate portion 12 to be attached to the fixed portion of the wall base 31. A regulating support portion 13 that protrudes, a horizontal piece 14 that protrudes forward from the fastening plate portion 12 between the regulation support portions 13 and extends horizontally in the left-right direction, and an outer wall that hangs downward at the tip of the horizontal piece 14. A hanging piece 15 that locks the upper end insertion piece 24 of the material 21, and an upright piece 16 that rises upward at the tip of the horizontal piece 14 along with the hanging piece 15 and locks the lower end insertion piece 26 of the outer wall material 21. Have.

  The fastening plate portion 12 has a plurality of screw holes 17 for fixing, is a rectangular shape that is long in the left-right direction, and is a portion where almost the entire back surface contacts the wall base 31. A bulging portion 12a having a triangular longitudinal section is formed in a straight line on the upper portion of the fastening plate portion 12 so that screws (not shown) can be inserted obliquely downward into some of the screw holes 17. Those screw holes 17 are formed in the upper surface of the bulging portion 12a.

  The restriction support piece 13 is used to form the air passage 41, and is formed by bending the left and right side edges of the fastening plate portion 12 forward to a necessary length. The front end edge of the regulation support piece 13 has a support surface portion 13a that projects outward in the left-right direction. The surface of the support surface portion 13 a is a portion that receives the back surface of the outer wall material 21. The lower part of the restriction support piece 13 in the vertical direction protrudes below the lower end position of the fastening plate part 12.

  The horizontal piece 14 is formed at the lower end of the fastening plate portion 12 by bending. As shown in FIG. 4C, which is a side view of the metal fitting, the horizontal piece 14 projects forward from the regulation support piece 13. The forward protrusion length of the horizontal piece 14 depends on the forward protrusion length of the restriction support piece 13, the size of each part of the joint structure portions 22 and 23 of the outer wall material 21, and the shape of the hanging piece 15 and the standing piece 16. Set as appropriate. The length of the horizontal piece 14 in the left-right direction is slightly shorter than the length of the fastening plate 12 in the left-right direction. One drooping piece 15 and two standing pieces 16 are arranged over the entire left and right direction at the tip edge of the horizontal piece 14.

  The drooping piece 15 is formed by being bent at a right angle toward the lower side in the middle portion of the horizontal piece 14 in the left-right direction (see FIG. 4A which is a cross-sectional view taken along the line AA in FIG. 3). The length in the left-right direction is set as appropriate, and the length in the vertical direction is set so that a good locking state can be obtained between the upper end insertion piece 24 and the restriction support piece 13.

  The upright pieces 16 are formed on both side portions in the left and right direction at the front end edge of the horizontal piece 14, that is, on both left and right portions of the hanging piece 15 with a slight gap between the hanging pieces 15. These upright pieces 16 are supported by a bent convex portion 16a formed at the base of the upright pieces 16 so as to be elastically displaceable. The bent convex portion 16 a protrudes below the horizontal piece 14, and comes into contact with a facing portion of the outer wall material 21 when the joint structure portion 23 on the lower side of the outer wall material 21 is fitted. Moreover, the cross-sectional shape of the bending convex part 16a is a semicircular arc shape (refer FIG.4 (b) which is BB sectional drawing of FIG. 3).

  That is, the standing piece 16 bends downward from the edge of the horizontal piece 14 and then curves upward to draw a semicircular arc. The standing piece 16b is slightly inclined from the tip to the rear, that is, toward the mounting plate portion. The tip is inclined slightly upward and extended to form the tip inclined portion 16c, and the overall shape is a substantially J-shaped longitudinal section. The tip inclined portion 16 c is a portion that contacts the inclined surface 26 a extending from the lower end of the lower end insertion piece 26 of the outer wall material 21 toward the upper end of the locking space 27. The length of the upright piece 16 in the vertical direction is set so that a good locking state can be obtained between the upright piece 16 and the lower end insertion piece 26 as in the case of the hanging piece 15.

  When a load in the direction in which the upright piece 16 is tilted forward is applied to the upper part of the upright piece 16 having such a shape, the load is mainly applied to the entire bent convex portion 16a and the portion between the bent convex portion 16b and the horizontal piece 14. To distribute.

  Further, as shown in FIG. 5, the size of the bent convex portion 16a is set so as to be compatible with a plurality of types of outer wall materials 21 in which the shape of the joint structure portion 22 on the upper side is different.

  That is, when the width of the upper end surface 24a of the upper end insertion piece 24 of the outer wall member 21 is wide in the front-rear direction, the bent convex portion 16a abuts the upper end surface 24a on the lower surface of the bent convex portion 16a (FIGS. 6 and 7). When the width is narrow, the upper end surface 24a is received in the rear space and is brought into contact with or close to the lower surface of the horizontal piece 14 (see FIGS. 8 and 9).

  In addition, the lower part of the upper end insertion piece 24 whose upper end surface 24a is narrower than the upper end surface 24a has an inclined surface 24b that extends obliquely toward the notch step 25. For this reason, the bending convex part 16a contact | abuts to this inclined surface 24b.

  In FIGS. 5 and 8, 29 is a sealing material.

The metal fitting 11 configured as described above is used as follows.
As shown in FIGS. 6 and 8, the metal fitting 11 is locked to the joint structure portion 22 on the upper side of the outer wall member 21 fixed to the lower side. The locking is performed by inserting an upper end insertion piece 24 between the restriction support portion 13 and the hanging piece 15. In the locked state, when the upper end surface 24a of the upper end insertion piece 24 is wide, as shown in FIGS. 6 and 7, the bent protrusions 16a of the upright pieces 16 located on the left and right sides of the hanging piece 15 are provided. The lower end contacts the upper end surface 24 a of the upper end insertion piece 24. This state is extremely stable because the upper end surface 24a of the upper end insertion piece 24 does not contact the horizontal piece 14, but the bent convex portions 16a are at two left and right positions. Moreover, since the upper end insertion piece 24 is sandwiched between the restriction support portion 13 and the hanging piece 15, it can be fixed without rattling.

  When the upper end surface 24 a of the upper end insertion piece 24 is narrow, as shown in FIGS. 8 and 9, the curved lower surface portion of the bent convex portion 16 a is lower than the upper end surface 24 a of the upper end insertion piece 24. The upper end surface 24a is in contact with or close to the lower surface of the horizontal piece 14. This state is also very stable because the bent convex portions 16a are at two left and right positions and the upper end insertion piece 24 enters the space behind the bent convex portions 16.

  Subsequently, the metal fitting 11 locked to the joint structure portion 22 on the upper side is fixed to the wall base 31 by inserting a screw (not shown) into the screw hole 17.

  Next, the joint structure portion 23 on the lower side of the outer wall member 21 connected to the upper side is locked to the metal fitting 11 from above.

  The lower end insertion piece 26 of the outer wall material 21 is locked to the rear side of the upright piece 16, the tip inclined portion 16 c of the upright piece 16 abuts on the inclined surface 26 a of the outer wall material 21, and the covering piece 28 of the outer wall material 21 It fits in the notch step part 25, and the joining state of the outer wall materials 21 is obtained.

  In such a fixed state of the outer wall member 21, even when a load is applied in the direction of peeling the outer wall member 21 as shown by the phantom line arrow in FIG. As shown by the solid line arrow, the upright piece 16 acts to hold the outer wall material 21 against the wall base 31, so that a firm fixed state is obtained.

  In addition, the bent convex portion 16a of the upright piece 16 supports the upright piece 16 so that it can be elastically displaced so that no concentrated load is applied, so that the strength and durability are high, even when a large load is applied due to an earthquake or the like. Can be maintained. In addition, since the bent convex portion 16a of the upright piece 16 disperses the load while being supported by being supported by the upper end insertion piece 24 of the outer wall member 21, a higher elasticity can be obtained.

  In addition, since the locking of the upper side of the outer wall material 21 to the bonding structure portion 22 and the locking of the lower side of the outer wall material 21 to the bonding structure portion 23 can be performed firmly, rattling occurs between the outer wall material 21 and the metal fitting 11. This also has the effect of suppressing the deterioration of the fixed structure.

  Furthermore, the bending convex part 16a can also fix a plurality of types of outer wall materials 21 having different shapes of the upper end insertion piece 24 portion. In particular, since the bent convex portion 16a has a semicircular cross section, the allowable range of the shape of the upper end insertion piece 24 when the upper end surface is narrow is wide, and the applicable range of the metal fitting 11 is expanded. In addition, when the upper end surface 24a is narrow, a state in which the upper end surface 24a is sandwiched by the lower curved surface of the bent convex portion 16a is obtained, and the locking state becomes stronger, so there is no backlash. The effect of obtaining a state can be further enhanced.

  Hereinafter, other examples will be described. In this description, parts that are the same as or equivalent to those in the above-described configuration are given the same reference numerals, and detailed descriptions thereof are omitted.

  FIG. 10 is a cross-sectional view showing a usage state of the metal fitting 11 according to another example. As shown in this figure, a bent protrusion 15a may be formed on the hanging piece 15 as well. In this case, the bent convex portion 15 a may have a shape that fits into the lower portion of the locking space 27. This is because the bent convex portion 15a fixes the joint structure portion 23 on the lower side of the outer wall material 21 with elasticity.

  When such a bent convex portion 15a is provided, the bent convex portion 16a of the upright piece 16 can be omitted.

  FIG. 11 is a perspective view of a metal fitting 11 according to another example. This metal fitting 11 is an example in which the protruding length of the restriction support portion 13 to the front is increased so that the ventilation space 41 (see FIG. 2) can be widened. In this case, an inclined portion 13b that is inclined rearward toward the upper end side can be formed on the upper portion of the support surface portion 13a of the restriction support portion 13 to facilitate insertion of the outer wall material 21.

The fixing surface of the present invention corresponds to the fixing portion of the wall base 31,
The present invention is not limited to the above-described configuration, and other configurations can be employed.

  For example, the hanging piece 15 and the standing piece 16 can be formed at the same position in the left-right direction of the horizontal piece 14.

  Further, the regulation support portion 13 can be omitted.
