  In general, in this type of outer wall plate mounting bracket, it is required to reduce the size of the entire mounting bracket as much as possible in order to reduce the amount of metal plate used as a raw material and reduce costs. However, when the size of the entire mounting bracket is reduced, the size of the claw portion that is necessarily engaged with the outer wall plate is also reduced.

  For this reason, conventionally, when a large force acts in the direction (front) of pulling the outer wall plate away from the building frame during a typhoon or the like, a large pressure concentration occurs in the portion of the outer wall plate that contacts the claw portion, There has been a problem that damage such as cracks may occur in the outer wall plate.

  In addition, since the front projecting portion is formed by being simply bent at a right angle from the outer wall plate back surface abutting portion, in the event of an earthquake or the like, the front projecting portion is perpendicular to the front projecting portion (the so-called up-and-down direction in the case of lateral tension, so-called When a large load is applied in the vertical direction (in the horizontal direction and in the direction parallel to the outer wall of the building), a large concentrated load is generated in the vicinity of the base end of the front protrusion, that is, the bent portion, and the bent portion is plastically deformed. There was a problem that it may be damaged.

  The present invention has been made in view of such conventional circumstances, and one of the objects of the present invention is to increase the size of the claw portion without increasing the size of the entire outer wall plate mounting bracket. Even if a large force acts in the direction (front) to pull the outer wall plate away from the building frame during a typhoon or the like, a large pressure concentration occurs in the portion of the outer wall plate that contacts the claw part, and the outer wall An object of the present invention is to provide an outer wall plate mounting bracket that can prevent the plate from being damaged such as cracks.

  Another object of the present invention is to provide an outer wall plate mounting bracket capable of improving the strength in the vicinity of the base end portion of the front protrusion in the direction perpendicular to the front protrusion.

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

It becomes easy to do.

  Therefore, even when a large force is applied to the outer wall plate in the case of a typhoon or the like, the claws support the outer wall plate flexibly, so that the outer wall plate may be damaged such as cracks. Can not be.

  In addition, since the front projecting portion is not simply bent at a right angle from the outer wall plate rear surface contact portion as in the prior art, a curved surface portion is provided between the front projecting portion and the outer wall plate rear surface contact portion. Even if a large load is applied in a direction perpendicular to the front protrusion, a large concentrated load is not generated on the curved surface portion. Therefore, the strength near the base end of the front protrusion in the direction perpendicular to the front protrusion is increased. Can be improved. Therefore, even in the event of an earthquake or the like, even if a large load is applied in the vertical direction to the front protrusion, the vicinity of the base end of the front protrusion can be prevented from being plastically deformed or damaged.

The outer wall plate mounting bracket of the present invention is

  The outer wall plate mounting bracket 1 is formed by pressing a single metal plate made of a steel plate, a stainless steel plate, an aluminum alloy plate, or the like. Most of the mounting bracket 1 is raised by drawing. Reference numeral 5 denotes the raised drawing portion 5, and the direction of the raised portion is such that the mounting bracket 1 is directly attached to the building housing 3, or an interposing material 4 such as a base material such as a trunk edge or a stud or a heat insulating material. When attached via (see FIGS. 9 and 10), the direction (front) is the opposite side of the building housing 3 side. A rectangular edge 6 is provided on the outer periphery of the outer wall plate mounting bracket 1, and this edge 6 surrounds the outer periphery of the drawn portion 5. The edge 6 is entirely on one plane and is brought into contact with the building housing 3 directly or via the interposing material 4.

  The top portion of the drawing portion 5 is flat and forms an outer wall plate rear surface abutting portion 7. The outer wall plate rear surface abutting portion 7 is in contact with the rear surface of the outer wall plate 2. It has become. Near the upper end portion of the drawing portion 5, a slope portion 8 is formed in the vicinity of the upper end portion of the mounting bracket 1, and a nail hole 9 is provided in the slope portion 8. Below the inclined surface portion 8 of the mounting bracket 1, a rectangular non-raised portion 10 is provided so as to be surrounded by the drawing portion 5. The non-protruding portion 10 is on the same plane as the edge portion 6, and is brought into contact with the building housing 3 together with the edge portion 6 directly or via the interposing material 4. Further, a screw hole 11 is provided in the non-raised portion 10. The nail hole 9 and the screw hole 11 are used to nail or screw the mounting bracket 1 to the building housing 3 via the interposing material 4 or are usually used.

  An outer wall plate engaging portion 13 formed by cutting and raising a part of the metal plate material is provided below the non-raised portion 10, and the outer wall plate engaging portion 13 includes a front protrusion 14, It has one claw portion 15 and a second claw portion 16. The front projecting portion 14 projects to the side (front) opposite to the building housing 3 in the horizontal plane. The first claw portion 15 is formed by being bent obliquely upward from the front end portion of the front projecting portion 14. The second claw portion 16 is formed by being bent obliquely downward from the front end portion of the front projecting portion 14.

  A cut-and-raised opening 17 is formed below the front protrusion 14. A part of the cut-and-raised trace opening 17 is a trace from which the outer wall plate engaging portion 13 is cut and raised, and the remaining part of the cut-and-raised trace opening 17 is a trace from which the metal plate material has been cut.

  2 and 8, as shown in FIGS. 2 and 8, near the both ends in the width direction of the base end portion of the front projecting portion 14, the cut-and-raised trace opening 17 and the outer wall plate back surface abutting portion are in contact with both ends. A cut 18 is cut toward 7. These cuts 18 are not linear but have a slight width when viewed in the front direction (perpendicular to the paper surface in FIG. 2), and the outer periphery of the front end of the cut 18 has a semicircular shape. ing.

  A curved surface portion 19 is provided between the two cuts 18. 5 and 7, the curved surface portion 19 is interposed between the outer wall plate back surface abutting portion 7 and the front projecting portion 14, and the outer wall plate back surface abutting portion 7 extends to the outer wall. It curves so that it may reach the front protrusion part 14 through the position which will approach the building skeleton 3 side from the board back surface contact part 7. FIG.

  Next, the mounting operation and the mounting completion state of the outer wall plate 2 by the mounting bracket 1 will be described with reference to FIGS. 9 and 10 are so-called horizontal stretches (a stretch in which the outer wall plate 2 is horizontally long, the upper end portion and the lower end portion of each outer wall plate 2 are abutted, and the outer wall plate 2 is sequentially attached from the lower stage side to the upper stage side. This shows how to install the case. Further, in this example, the mounting bracket 1 is attached to the building frame 3 via the interposing material 4 which is a base material such as a trunk edge or a stud.

  A first real part 20 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 formed at the lower end portion (see FIG. 10) of each outer wall plate 2. The second real part 21 is formed by notching. Further, an engaging groove 22 is formed at the lower end of each outer wall plate 2 so as to contact the inner surface of the second real part 21.

  In this case, first, as shown in FIG. 9, the lower outer wall is provided between the second claw portion 16 and the front projecting portion 14 of the outer wall plate engaging portion 13 of the mounting bracket 1 and the outer wall plate back surface abutting portion 7. The outer wall plate engaging portion 13 of the mounting bracket 1 is engaged with the upper end portion of the lower outer wall plate 2 so that the first real part 20 of the plate 2 is inserted, and the outer wall plate rear surface abutting portion 7 is engaged. Is brought into contact with the back surface of the lower outer wall plate 2. At this time, the front protruding portion 14 of the mounting bracket 1 is oriented in the horizontal direction, and the edge 6 and the non-raised portion 10 are in contact with the interposition material 4.

  Next, the nail 23 is used to nail the mounting bracket 1 to the interposing material 4 as shown in FIG. 10 and the mounting bracket 1 is attached to the building frame 3 via the interposing member 4 (see FIG. 10). Note that the mounting bracket 1 may be screwed using the screw hole 11 instead of using the nail 23 as described above. As a result, the attachment fitting 1 is fixed to the intervention member 4 in a state where the edge portion 6 and the non-raised portion 10 are in contact with the intervention member 4, and as a result, the outer wall plate 2 on the lower stage side is interposed via the attachment fitting 1. The upper end is attached to the building frame 3.

  Subsequently, as shown in FIG. 10, the first claw portion 15 of the mounting bracket 1 is inserted into the engagement groove 22 at the lower end portion of the upper outer wall plate 2, and the lower end of the upper outer wall plate 2. The portion on the back side of the engaging groove 22 of the portion is inserted between the first claw portion 15 and the front projecting portion 14 of the outer wall plate engaging portion 13 and the outer wall plate rear surface abutting portion 7, so that the outer wall plate 2 on the upper stage side is inserted. The outer wall plate engaging portion 13 of the mounting bracket 1 is engaged with the lower end portion of the upper outer wall plate 2 so that the lower end portion of the upper outer wall plate 2 is placed on the front projecting portion 14. The lower end portion is butted against the upper end portion of the outer wall plate 2 on the lower stage side.

  Thereafter, in the same manner, the outer wall plate 2 is sequentially attached from the lower stage side to the upper stage side, so that the outer wall board 2 can be attached to the building frame 3 in a state where the outer wall plates 2 face each other up and down ( The front projecting portion 14 of the outer wall plate engaging portion 13 of the mounting bracket 1 is interposed between the upper and lower end portions of the outer wall plate 2 that are abutted with each other).

  In such an attachment state, the front projecting portion 14 is opposed to or abuts on the upper and lower end portions of the outer wall plate 2 to prevent the outer wall plate 2 from moving in the vertical direction. Further, the outer wall plate rear surface abutting portion 7 is in contact with the rear surface of the outer wall plate 2 to prevent the outer wall plate 2 from moving to the building housing 3 side, and the rear surface of the outer wall plate 2 and the interposing material 4 and thus the building housing. A certain gap is ensured between 3 and 3.

  In addition, although the case where what is called horizontal stretch was demonstrated here, what is called vertical stretch (The outer wall board 2 is made into elongate, the left end part and right end part of each outer wall board 2 are faced | matched, and sequentially from left to right or right to left side. 9), the mounting bracket 1 is rotated 90 degrees, that is, the front projecting portion 14 is in a vertical direction. As in the case of 9 and 10, the mounting bracket 1 can be used to attach the outer wall plate 2 to the building frame 3 via the interposing material 4 (the vertical mounting of the mounting bracket 1 in the case of horizontal stretching is therefore In the case of left and right).

  In this outer wall plate mounting bracket 1, as is well shown in FIGS. 2 and 8, the outer wall plate back surface abutting portion 7 is in contact with both ends of the base end portion of the front projecting portion 14 from the cut and raised opening 17. In addition, as shown in FIGS. 5 and 7, a curved surface portion 19 is formed between the outer wall plate back surface abutting portion 7 and the front protruding portion 14. Therefore, as shown by the arrows in FIG. 7, the outer wall plate engaging portion 13 is easily elastically displaced in a wide range with respect to a direction perpendicular to the building wall surface (front-rear direction).

  Accordingly, even when a large force is applied to the outer wall plate 2 to be separated from the building housing 3 during a typhoon or the like, the first and second claw portions 15 and 16 flexibly support the outer wall plate 2. The outer wall plate 2 can be prevented from being damaged such as cracks.

  In the present embodiment, the outer periphery of the tip of the notch 18 is semicircular, so the notch 18 can be prevented from having a notch effect.

  In addition, the front protrusion 14 is not simply formed at a right angle from the outer wall plate back surface abutting portion 7 as in the prior art, but a curved surface 19 is provided, so that the direction perpendicular to the front protrusion 14 ( Even if a large load is applied in the vertical direction in the case of horizontal tension, the horizontal direction in the case of vertical tension and a direction parallel to the outer wall surface), a large concentrated load does not occur on the curved surface portion 19. On the other hand, the strength in the vicinity of the base end portion of the front protruding portion 14 in the direction perpendicular to the vertical direction can be improved. Therefore, even in the event of an earthquake or the like, even if a large load acts on the front projecting portion 14 in the vertical direction, the vicinity of the base end portion of the front projecting portion 14 can be prevented from being plastically deformed or damaged.
