Description

  The present invention relates to an outer wall plate mounting bracket for mounting a panel-shaped outer wall plate (sometimes referred to as an outer wall material or an exterior material) to a building frame.

  In recent years, as a method of attaching an outer wall plate to a building frame, a method of attaching the outer wall plate to the building frame via a mounting bracket has become common.

  The applicant of the present application previously described in Patent Document 1 can significantly increase the strength and rigidity by providing a press-drawn portion, and a large force is applied during construction, or after construction, wind, earthquake, etc. We have proposed mounting brackets for panel-like materials such as outer wall plates that do not easily deform even when a large force is applied and are less likely to cause abnormalities in the mounting state of the outer wall plates.

Japanese Patent No. 2968271 JP 2012-112220 A

  However, in the outer wall plate mounting bracket proposed by the present applicant in Patent Document 1, since the bracket supports the outer wall plate rigidly, when a large force acts on the outer wall plate due to strong wind or the like, the outer wall plate cracks. There is a problem that, when a large shock is applied due to a large earthquake or the like, the shock may not be absorbed.

  Further, although the present applicant has proposed an outer wall plate mounting bracket in Patent Document 2 that can solve the problem of the outer wall plate mounting bracket proposed in Patent Document 1, there is still a point that the problem cannot be solved sufficiently.

  The present invention has been made in view of such conventional circumstances, and one of the objects of the present invention is to support the outer wall plate flexibly, even if a large force acts on the outer wall plate due to strong winds or the like. In addition to reducing the risk of the outer wall plate being cracked, it is possible to absorb the impact even when a large impact is applied due to a large earthquake, etc., and the portion of the mounting bracket that requires high strength and rigidity An object of the present invention is to provide an outer wall plate mounting bracket capable of securing a large strength and rigidity as required.

  Other objects of the present invention will become apparent from the following description.

The outer wall plate mounting bracket according to the present invention is:
In the outer wall plate mounting bracket that is formed by molding a metal plate material and is attached to the building frame in a state where the end portions of these outer wall plates are butted against each other,
A main part that is formed by press drawing so as to be recessed in the building housing side, and is attached to the building housing directly or via an interposition material;
An outer wall plate back contact portion that is in contact with the back surface of the outer wall plate;
Outside the main part, an engagement part support that protrudes from the opening edge of one end of the main part or the vicinity thereof in a direction parallel to the wall surface to be formed by the outer wall plate and toward the opposite end of the main part And
An outer wall plate engaging portion provided at the distal end of the engaging portion supporting portion,
The outer wall plate engaging portion includes a front protruding portion that is bent so as to protrude from the distal end portion of the engaging portion supporting portion to the opposite side of the building housing, and an opposite side from the distal end portion of the front protruding portion. Having a bent first bent portion and a second bent portion,
The end portions of the outer wall plates that face each other are between the second bent portion, the front protruding portion, and the outer wall plate rear surface abutting portion, and the first bent portion, the front protruding portion, and the outer wall plate. It is inserted between the back surface contact portion and engaged with the outer wall plate engaging portion, and the front protruding portion is interposed in the abutting portion between the outer wall plates. .

  In the conventional outer wall plate mounting bracket including the outer wall plate mounting bracket of Patent Document 1, the front wall protruding portion of the outer wall plate engaging portion is directly bent from the main component part on the strength of the mounting bracket, and the building frame Therefore, the flexibility in the direction of the thickness direction of the outer wall plate and the direction of butting of the outer wall plate was poor. In addition, in the mounting bracket of Patent Document 2, an engaging portion support portion is interposed between the drawn main portion, which is a main component in strength of the mounting bracket, and the front protruding portion of the outer wall plate engaging portion. However, this engagement portion support portion did not contribute to flexibly supporting the outer wall plate.

  However, in this outer wall plate mounting bracket, the direction parallel to the wall surface to be formed by the outer wall plate from the vicinity of the opening edge of one end of the main portion, which is the main component of the strength of the mounting bracket, and the opposite side of the main portion An engaging portion supporting portion that protrudes toward the end is provided, and the front protruding portion is not directly from the main portion, but is bent so as to protrude from the distal end portion of the engaging portion supporting portion to the opposite side of the building frame. Therefore, the outer wall plate engaging portion can be elastically displaced in the thickness direction of the outer wall plate by elastically bending and deforming the engaging portion supporting portion around the vicinity of the end portion on the main portion side. Furthermore, because of other types of elastic deformation such as bending of the engaging portion support portion and elastic deformation of the front protruding portion, the outer wall plate engaging portion is also in the abutting direction of the outer wall plate (in this embodiment, the vertical direction). Can be elastically displaced. Therefore, since the outer wall plate engaging portion flexibly supports the outer wall plate in the thickness direction and the butting direction of the outer wall plate, even if a large force acts on the outer wall plate due to strong winds or the like, the risk of the outer wall plate breaking is reduced. In addition, even if a large impact acts due to a large earthquake or the like, the impact can be absorbed.

  And on the other hand, it is the main component part on the strength of the mounting bracket, and the main part that is attached to the building frame directly or via the interposing material is formed by press drawing, so the strength of the mounting bracket is great In a portion where rigidity is required, a high strength and rigidity can be ensured as required.

  The outer wall plate mounting bracket of the present invention reduces the possibility that the outer wall plate will be broken even if a large force acts on the outer wall plate due to strong wind or the like by flexibly supporting the outer wall plate in the thickness direction and the butting direction. In addition, even if a large impact is applied due to a large earthquake, etc., the impact can be absorbed, and the part of the mounting bracket that requires high strength and rigidity has high strength as required. In addition, excellent effects such as ensuring rigidity can be obtained.

  The opening portion-side peripheral wall extension portion 5 and the engagement portion-side peripheral wall extension portion 7 are separated from each other by the cut portion 12, and the upper end of the opening portion-side peripheral wall extension portion 5 (opposite to the engaging portion-side peripheral wall extension portion 7) Since the end of the opening part side peripheral wall extension part 5 and the engagement part side peripheral wall extension part 7 are not subjected to drawing processing, the end part of the main part 4 is not connected to the other part. It has become.

  The pair of opening portions 6 are provided at the front end portion of each opening portion side peripheral wall extension portion 5 opposite to the building housing 3 by being bent at right angles outward from each opening portion peripheral wall extension portion 5 by press bending. It has been. The pair of opening portions 6 have a planar shape parallel to the substrate portion 4a (therefore, after mounting, the pair of opening portions 6 has a planar shape parallel to the wall surface to be constituted by the outer wall plate 2). The engagement portion support portion 8 is bent at a right angle from the tip of the engagement portion side peripheral wall extension portion 7 by a press bending process and is parallel to the substrate portion 4a (parallel to the wall surface to be constituted by the outer wall plate 2). Projecting toward the opposite end of the main portion 4 (upper end of the main portion 4). In the present embodiment, the left and right opening portions 6 and the engaging portion support portion 8 constitute an outer wall plate rear surface abutting portion that is brought into contact with the rear surface of the outer wall plate 2 in the present invention.

  The outer wall plate engaging portion 9 is provided at the distal end portion (upper end portion) of the engaging portion supporting portion 8, and includes a front protruding portion 13, a first bent portion 14, and a second bent portion 15. Have. The front protruding portion 13 is bent so as to protrude from the distal end portion of the engaging portion supporting portion 8 to the opposite side of the building housing 3 by press bending. The first bent portion 14 is bent obliquely upward from the front end portion of the front protruding portion 13 by press bending, while the second bent portion 15 is inclined from the front end portion of the front protruding portion 13 by press bending. It is bent downward.

  Next, an example of the mounting structure of the outer wall plate 2 by the mounting bracket 1 will be described with reference to FIGS. 11 and 12 show an attachment method in the case of performing so-called lateral pasting. Moreover, in this example, it is supposed that the mounting bracket 1 is attached to the building frame 3 via the interposing material 10 which is a base material such as a trunk edge or a stud. A first real part 16 is formed at the upper end portion of each outer wall plate 2 by cutting out the outer surface side, while the inner surface side is cut off at the lower end portion (see FIG. 12) of the outer wall plate 2. The second real part 17 is formed by lacking. An engaging groove 18 is formed at the lower end of each outer wall plate 2 so as to contact the inner surface of the second real part 17.

  In this case, first, as shown in FIG. 11, between the second bent portion 15 of the outer wall plate engaging portion 9 of the mounting bracket 1, the front protruding portion 13, the left and right opening portions 6, and the engaging portion supporting portion 8. The outer wall plate engaging portion 9 of the mounting bracket 1 is engaged with the upper end portion of the lower-stage outer wall plate 2 so that the first real part 16 at the upper end portion of the lower-stage outer wall plate 2 is inserted into The left and right opening portions 6 and the engagement portion support portion 8 are brought into contact with the back surface of the lower outer wall plate 2. At this time, the mounting bracket 1 is set so that the front protruding portion 13 is in the horizontal direction and the substrate portion 4a is in contact with the interposing material 10.

  Next, as shown in FIG. 12, the mounting bracket 1 is screwed to the interposing material 10 with the screw 19 using the screw hole 11, and the mounting bracket 1 is attached to the building frame 3 via the interposing material 10. As a result, the mounting bracket 1 is fixed to the interposing material 10 in a state where the substrate portion 4a is along the interposing member 10, and as a result, the upper end portion of the outer wall plate 2 on the lower stage side is connected to the building frame via the mounting bracket 1. 3 is attached. Subsequently, the first bent portion 14 of the mounting bracket 1 is caused to enter the engaging groove 18 at the lower end portion of the upper outer wall plate 2, and the rear side from the engaging groove 18 at the lower end portion of the upper outer wall plate 2. Is inserted into a portion between the first bent portion 14, the front projecting portion 13 and the left and right opening portions 6 of the outer wall plate engaging portion 9, and the lower end portion of the outer wall plate 2 on the upper stage side is the front projecting portion 13. The outer wall plate engaging portion 9 of the mounting bracket 1 is engaged with the lower end portion of the upper-side outer wall plate 2 so as to be placed on the lower-side outer wall plate. Butt the top of 2.

  Thereafter, in the same manner, by sequentially attaching the outer wall plate 2 from the lower stage side to the upper stage side, it is possible to attach the outer wall plate 2 to the building frame 3 in a state in which the outer wall plate 2 is abutted up and down. Between the upper and lower ends of the plate 2, the front protruding portion 13 of the outer wall plate engaging portion 9 of the mounting bracket 1 is interposed).

  In such an attached state, the front projecting portion 13 is opposed to or abutted against the upper and lower end portions of the outer wall plate 2 to prevent vertical movement. Further, the left and right opening portions 6 and the engaging portion support portions 8 are in contact with the back surface of the outer wall plate 2 to prevent the outer wall plate 2 from moving toward the building housing 3 side, and the rear surface of the outer wall plate 2 and the interposition. A certain gap is secured between the material 10 and the building frame 3.

  Here, the case of performing so-called horizontal bonding has been described. However, in the case of performing so-called vertical bonding, the direction in which the mounting bracket 1 is rotated by 90 degrees as compared with FIGS. 11 and 12, that is, the front protrusion 13 is in the vertical direction. 11 and 12 can be used to attach the outer wall plate 2 to the building frame 3 via the interposing material 10 in the same manner as in FIGS.

  In the conventional outer wall plate mounting bracket including the outer wall plate mounting bracket of Patent Document 1, the front wall protruding portion of the outer wall plate engaging portion is directly bent from the main component part on the strength of the mounting bracket, and the building frame Therefore, the flexibility in the direction of the thickness direction of the outer wall plate and the direction of butting of the outer wall plate was poor. In addition, in the mounting bracket of Patent Document 2, an engaging portion support portion is interposed between the drawn main portion, which is a main component in strength of the mounting bracket, and the front protruding portion of the outer wall plate engaging portion. However, this engagement portion support portion did not contribute to flexibly supporting the outer wall plate.

  However, in this outer wall plate mounting bracket 1, the direction parallel to the wall surface to be formed by the outer wall plate 2 from the vicinity of the opening edge of one end of the main portion 4, which is the main component of the strength of the mounting bracket 1, An engaging portion support portion 8 that protrudes toward the opposite end of the portion 4 is provided, and the front protruding portion 13 is not directly from the main portion 4 but from the distal end portion of the engaging portion support portion 8 to the building housing 3. 9 so that the engagement portion support portion 8 is elastically bent and deformed around the end portion on the main portion 4 side as indicated by a one-dot chain line and an arrow in FIG. Thus, the outer wall plate engaging portion 9 can be elastically displaced in the thickness direction of the outer wall plate 2. Furthermore, because of other types of elastic deformation such as bending of the engaging portion support portion 8 and elastic deformation of the front protruding portion 13, the outer wall plate engaging portion 9 is in the abutting direction of the outer wall plate 2 (in this embodiment, vertical). Direction). Accordingly, since the outer wall plate engaging portion 9 flexibly supports the outer wall plate 2 in the thickness direction and the butting direction of the outer wall plate 2, the outer wall plate 2 is cracked even if a large force acts on the outer wall plate 2 due to strong winds or the like. Can be absorbed even if a large impact is applied due to a large earthquake or the like (note that the alternate long and short dash line in FIG. 9 indicates the outer wall plate engaging portion for easy understanding). 9 is exaggerated and greatly shown, and usually it is not actually so greatly deformed).

  In addition, in this embodiment, the engagement portion support portion 8 is not directly continuous with the main portion 4, and the engagement portion side peripheral wall extension portion 7 is further provided between the engagement portion support portion 8 and the main portion 4. Since it is interposed, the elastic displacement of the engaging portion side peripheral wall extension 7 further increases the elastic displacement of the outer wall plate 2 in the thickness direction of the outer wall plate engaging portion 9 and the butting direction of the outer wall plate 2. Therefore, the outer wall plate 2 can be supported more flexibly in these directions.

  And since the main part 4 which is a main structural part on the strength of the mounting bracket 1 and is attached to the building housing 3 directly or via the interposing material 10 is formed by press drawing, In parts where high strength and rigidity are required, high strength and rigidity can be secured as required.

  Furthermore, in this embodiment, the opening portion side peripheral wall extension portion 5 is provided outside the main portion 4 so as to extend from the edge portion of the main portion 4 subjected to press drawing processing to the side opposite to the building housing 3. Since the opening part 6 is provided in the front-end | tip part of the side peripheral wall extension part 5, the outer wall board mounting bracket 1 supports the outer wall board 2 flexibly also by this. For this reason, even if a large force acts on the outer wall plate 2 due to strong winds or the like, the risk of the outer wall plate 2 being cracked is reduced, and even if a large impact is applied due to a large earthquake or the like, the shock is absorbed. To be able to.

  In the present embodiment, the drain hole 20 is useful for allowing rainwater that has entered the mounting bracket 1 to be discharged to the outside.

  13 to 18 show a second embodiment of the present invention. In the present embodiment, the upper end of the main portion 4 is not provided with the peripheral wall portion 4b, and the main portion 4 is not in a perfect container shape. For this reason, the main part 4 has the surrounding wall part 4b in the perimeter like Example 1, and the intensity | strength of the main part 4 becomes weaker than the case where the main part 4 becomes a perfect container shape. However, the drawing of the main part 4 is facilitated, and it is possible to reduce the occurrence of defects such as cracks and the amount of materials used, and to obtain advantages such as being able to use a press machine with a small capacity. .

  In addition, FIG. 14 is the figure which gave the main part 4 the net line in the perspective view of the attachment metal fitting 1 in order to clarify the range of the main part 4 (press drawing process part) in a present Example.

  Other configurations are the same as those of the first embodiment, and the same effects as those of the first embodiment can be obtained.

  In the present embodiment, a relatively large hole 21 is provided in the peripheral wall portion 4 b of the main portion 4. The hole 21 is formed by providing a hole having a shape corresponding to a corresponding position of the blank (material metal plate) of the mounting bracket 1 before drawing the main portion 4. By providing such a hole 21, the strength of the main portion 4 becomes weaker than when the hole 21 is not provided. However, the drawing of the main part 4 is facilitated, and it is possible to reduce the occurrence of defects such as cracks and the amount of materials used, and to obtain advantages such as being able to use a press machine with a small capacity. . And the hole 21 can be utilized as a drain hole.

  Further, in this embodiment, the opening portion side peripheral wall extension portion 5, the engagement portion side peripheral wall extension portion 7 and the cut portion 12 in the first and second embodiments are not provided. And the opening part 6 and the engaging part support part 8 are each following the opening edge part of the main part 4 directly. For this reason, the effect that the outer wall plate 2 can be more flexibly supported by the outer wall plate mounting bracket 1 by elastic deformation of the opening portion side peripheral wall extension portion and the engaging portion side peripheral wall extension portion cannot be obtained. . However, also in the present embodiment, as in the first and second embodiments, the opening portion side peripheral wall extension portion 5, the engagement portion side peripheral wall extension portion 7 and the cut portion 12 may be provided.

  Other configurations are the same as those of the first embodiment, and the same effects as those of the first embodiment can be obtained.

  In each of the above embodiments, the left and right opening portions 6 and the engaging portion support portion 8 constitute an outer wall plate rear surface abutting portion that contacts the rear surface of the outer wall plate 2, but in the present invention, the outer wall It suffices that the plate back surface abutting portion (the portion abutted against the back surface of the outer wall plate 2) is present, and the configuration itself of the outer wall plate back surface abutting portion may be different from the embodiment. For example, the engaging portion support portion 8 is provided at a position retracted from the opening portion 6 in the embodiment to the building housing 3 side, and only the opening portion 6 constitutes the outer wall plate back surface abutting portion, and the engaging portion support portion 8 is the outer wall. The plate back surface contact portion may not be configured, or the opening portion 6 in the embodiment may not be provided, and the opening edge of the main portion 4 may be used as the outer wall plate back surface contact portion.

  Further, in each of the above embodiments, the main wall 4 is provided with the screw hole 11 for screwing the outer wall plate mounting bracket 1 to the building housing 3 side, but instead of the screw hole, the outer wall plate mounting bracket is attached to the building.
