Description

  The present invention relates to a fastener used when attaching an outer wall material, and more particularly, to a fastener that can be applied to many manufacturer standards and various places by devising the shape and dimensions and has excellent workability.

  For the purpose of greatly improving the aesthetics of the appearance and improving the heat insulation and durability, an outer wall plate (exterior material) is often attached to the outer surface of the building. For the attachment, the upper and lower ends of the rectangular thin plate-like outer wall plate are fixed to the base material (such as the outer surface wall material of the building frame) using fastening brackets (ventilation brackets, brackets, fasteners). Things are done. At this time, the upper and lower end surfaces of the outer wall plate are stepped or notched from the standpoints of being firmly fixed, the outer surfaces of the upper and lower outer wall plates being flush with each other, and improving workability. Are formed, and the structure (including dimensions) and shape of the fastener are adapted to them.

  Specifically, the planar shape of the fastener attached to the base material is a substantially rectangular shape, and a horizontal portion that protrudes to the outside is formed at the center in the vertical direction. Alternatively, the central portion is bent downward or diagonally downward, and the central portion (or both right and left sides) is bent upward or diagonally upward. As a result, the horizontal portion bears the load of the upper outer wall plate, and the bending of the left and right sides and the central portion is fitted into the upper or lower outer wall plate steps or notches to fix them ( FIG. 1 of Patent Document 1 and FIG.

  However, the outer wall board is various because it needs to be adapted to the user's various hobbies and is still in the development stage. For this reason, there is no nationally standardized structure and shape for mounting the end face of the outer wall plate, and each manufacturer uses a unique standard with different details. Naturally, each manufacturer also uses a unique standard with different details for the fastener (Non-Patent Document 1 to 4).

As a countermeasure, there have been several utility model registrations for fasteners that are usually used for outer wall plates of flat parts of buildings and that have structures and shapes that can be applied to outer wall materials of multiple manufacturers (Patent Documents). 1, 2).

In addition, although a bolt, a nail, etc. are used for fixing to a base material of a fastener, and various other constructions are also made, since it is a well-known technique, description about these is abbreviate | omitted.

Kubota Matsushita Electric Works Co., Ltd. “Exterior wall material” catalog for general areas, published in December 2008 Nichiha Co., Ltd. “Exterior building materials full lineup catalog” issued in July 2009 Asahi Tostem Co., Ltd. catalog “AT-WALL” issued on March 1, 2009 Catalog “EXTERIOR & INTERRIOR” published by Kamishima Chemical Industry Co., Ltd., December 2009

However, all of the fasteners and the like according to the above-mentioned device only conform to the standards of two of the many manufacturers of outer wall plates, and are not versatile enough.
It seems that fasteners that meet the standards of more than three companies have been announced, but it is still not enough.
For this reason, as an actual problem, the worker of the installation work of the outer wall plate needs to arrange and store in advance a fitting suitable for each manufacturer of the outer wall plate to be implemented. For this reason, the stock burden, specifically, labor and cost increases.

  Furthermore, since the installation of the outer wall plate is done at the location of the building, the operator must bring a fastener that fits the outer wall plate to the work site, although the details of each standard fastener are different. The rough structure, shape, dimensions, and other materials and manufacturing methods are substantially the same and are easily misidentified. For this reason, it is necessary to pay sufficient attention at the time of departure so as not to accidentally bring another manufacturer's standard, and this also increases the stock burden.

In addition, when attaching the outer wall plate to the actual building, a special fastener is required because a long and thin plate outer wall plate having a cross section of “<(the angle between the two sides is 90 degrees)” is used at the corner of the building. In addition, the lower end of the outer wall plate at the bottom is not only used with dedicated fasteners, but there are also manufacturers standards for those fasteners, so the burden on the outer wall plate installation worker is even greater Become.

In addition, since the outer wall plate is attached to the actual building on site, it is preferable that the fasteners have a structure and shape considering workability as much as possible. It is difficult to say that fixing to the door and mounting of the outer wall plate are sufficient.

For this reason, it is desired to develop a fastener that not only conforms to a number of manufacturer standards but also has versatility in the types and locations of applicable outer wall plates, and has better workability than before. It was.

  As a result of intensive research to solve the above problems, the present applicant has found that the horizontal part of the fastener, the shape and size of the bent part at the left and right and center of the horizontal part, and the mounting part fixed to the base material The present invention has been completed by elaborating the rising position of the horizontal part from the top, the shape of the left and right support parts of the base, and the like. The contents of each claim will be described below.

The device described in claim 1
Attachment part to base material, side wall-shaped support part formed on the left and right of the attachment part, horizontal part formed between the lower end of the attachment part and the left and right support parts, and the center or left and right outside the horizontal part It has a bent portion that is formed obliquely upward on the both sides, and a bent portion that is formed on the left and right sides or the center outside the horizontal portion,
The side wall-shaped support part forms a guide part by making the transition from the upper apex part to the vertical direction of the outer end in a curved or inclined line shape,
The horizontal part has a lower surface at a position of 14.5 mm or less from the lower ends of the left and right support parts,
The downward bent part is stepped by bending both the left and right sides or the central part on the tip side of the horizontal part once downward and further horizontally bending, and further downward on the tip side of the part bent further horizontally. And the starting position of the step is 4.0 to 4.1 mm mm from the outer end of the vertical portion of the support portion, and the tip side is 1.1 ± 0.00 mm from the step. The surface on the base material side of the portion that is located 1 mm below and further bent 90 degrees downward is 6.85 to 6.95 mm from the outer end of the portion that forms the vertical direction of the support portion, and the outer surface is supported. Is located at a position of 7.85 to 7.95 mm from the outer end of the portion forming the vertical direction of the part, and its lower end is located at a position of 7.13 to 7.27 mm from the upper side surface of the base part side of the horizontal part,
The bent portion extending obliquely upward to the outside is 68 from the position of 4.0 to 4.08 mm obliquely upward from the outer end of the portion where the central portion or the left and right sides of the horizontal portion form the vertical direction of the support portion. The uppermost part of the bent part is located at a position of 6.65 to 6.75 mm from the outer end of the part perpendicular to the support part, and the length of the upper surface of the bent part is 7. 06-7.2 mm and the outermost end of the bent part does not come out from the outer surface of the bent part downward,
Further, the maximum horizontal width is 90 ° with the outer surface perpendicular to the corner and 90 mm or more on the inner side. This is a fastening member for an outer wall plate, characterized in that it is possible.

  In the invention of this claim, since the structure and shape including the dimensions of each part are appropriate, it is possible not only to attach each manufacturer's standard outer wall plate with only one type of fastener, but also to the bottom. It is possible to attach an outer wall plate and an outer wall plate at a corner of a building. For this reason, it is possible to reduce the labor, cost, mental burden, and the like of arranging the fasteners of the worker for the installation work of the outer wall plate, storing them and bringing them to the work site.

“The maximum width in the horizontal direction is 90 degrees with two fasteners on an outer wall plate having an outer surface perpendicular to the corner for 90 degrees and one side on the base material side (inner side) of 70 mm. In order to be able to be placed and crossed, it is preferred that the overall width is 58 mm or less.
For this reason, depending on the overall width of the fastener, the horizontal portion of the apex portion above the side wall-like support portion is not necessarily required, and sudden transition of the outer end in the vertical direction is curved or inclined. May be made.
Furthermore, as long as the requirements of the dimensions described in the claims are satisfied, the crossing angle between the two surfaces of the outer wall plate used in the actual building may not be 90 degrees.

Further, in principle, the step may be formed by bending, and the upper and lower ends of the step are usually rounded. Of course, other manufacturing methods may be square.
In addition, although “the tip side is located 1.1 ± 0.1 mm below”, due to manufacturing convenience, an error of about 0.01 mm is of course included in the right range.
Moreover, 7.2 mm is preferable for "7-10-7.3 mm from the upper surface of the base material side of the horizontal part".

  In addition, the dimensions described in the claims are only for adapting to the outer wall plates of many manufacturers and can be fixed, and the position, shape, dimensions, etc. of the parts unrelated to the fixing are limited to names, examples, etc. Of course it is not (restrained). For example, an unevenness is formed near the attachment portion of the horizontal portion to the base material to ensure strength. Similarly, unevenness may be formed to ensure strength across the horizontal portion formed between the attachment portion to the base material and the lower end of the attachment portion and the left and right support portions. Regarding the dimensions, the length in the front-rear direction of the side wall-shaped support portions formed on the left and right of the attachment portion may be 15.0 mm or 14.8 mm.

Moreover, although it is described in the claims as “bend”, this is only used for easy understanding of the shape and structure, and since it is a utility model, the manufacturing method is not required. For this reason, a bending part and a horizontal part support mechanism may be formed by attaching a plate piece by welding or adhesion (as an equivalent idea, it is included in the scope of rights).
Similarly, the material is not questioned.

Similarly, an elongated thin plate may be placed on the horizontal portion, or a curable resin (or adhesive) layer such as araldite may be formed to support the lower end of the outer wall plate located above through this. . That is, as long as the configuration described in the claims is provided, the outer wall plate may be fixed and supported more firmly using a general-purpose auxiliary material.
In addition, it is possible to substantially change the size and shape of the bent part downward and the bent part obliquely upward with the same means. May be dealt with flexibly.

  In addition, in order to adapt to the products of foreign manufacturers with different standards, etc., the details of the fasteners and outer wall plates that satisfy the above dimensions are shaved by about 0.05 mm on site processing, the bending is slightly changed, or deformed. May be used. In addition, if the difference is about 0.05 mm, on-site compensation and conforming work are possible.

The invention described in claim 2
Attachment part to base material, side wall-shaped support part formed on the left and right of the attachment part, horizontal part formed between the lower end of the attachment part and the left and right support parts, and the center or left and right outside the horizontal part It has a bent portion that is formed obliquely upward on the both sides, and a bent portion that is formed on the left and right sides or the center outside the horizontal portion,
The side wall-shaped support part forms a guide part by making the transition from the upper apex part to the vertical direction of the outer end in a curved or inclined line shape,
The horizontal part has a lower surface at a position of 15.0 mm or less from the lower ends of the left and right support parts,
The downward bent part is stepped by bending both the left and right sides or the central part on the tip side of the horizontal part once downward and further horizontally bending, and further downward on the tip side of the part bent further horizontally. The starting position of the step is located at 4.0 to 4.1 mm from the outer end of the vertical portion of the support portion, and the tip side is 1.0 to 2.0 mm depending on the step. The surface on the base material side of the portion located below and further bent 90 degrees downward is located at a position of 6.8 to 7.0 mm from the outer end of the portion perpendicular to the support portion, and the outer surface is the support portion. The lower end is located at a position of 7.8 to 8.0 mm from the outer end of the portion forming the vertical direction, and the lower end thereof is located at a position of 7.10 to 7.3 mm from the upper side surface of the base material side of the horizontal portion.
The bent part that extends diagonally upward is a part of the center part on the front end side of the horizontal part or both the left and right sides, etc. The uppermost part of the bent part is formed at a position of 6.6 to 6.8 mm from the outer end of the part that forms the vertical direction of the support part, and is formed on the upper surface of the bent part. The length is 7.1 to 7.24 mm, and the outermost end of the bent portion does not come out from the outer surface of the bent portion downward,
Furthermore, the maximum horizontal width is 90 degrees with an outer surface perpendicular to the corner and 90 mm or more on the inner side. This is a fastening member for an outer wall plate, characterized in that it is possible.

The device of this claim is easy to manufacture because of the wide tolerance of numerical values. As described above, cutting and deformation of about 0.05 mm are extremely easy even on site.

In addition, the bending angle of the outer obliquely upward bent portion to the outer oblique upper direction is set to “about 68 degrees”, which may be slightly different from 68 degrees for convenience of other dimensions (within the scope of rights). Is included).
Further, “the tip side is positioned 1.0 to 2.0 mm below depending on the step” is preferable, but “1.0 to 1.5 mm” is preferable depending on the rounding at the lower end of the step and the processing method.

The invention according to claim 3 is that the length of the upper end portion of the side wall-shaped support portion is less than 5.388 mm,
The outer wall plate fastening bracket is characterized in that the upper outer end excluding the upper end portion is bent to the left and right to form a wide guide portion of the outer wall plate that is lowered from above for attachment.

In the present invention, the length of the upper end portion of the side wall-shaped support portion is less than 5.388 mm, so that the lower end of the outer wall plate that is lowered from above for mounting, particularly the inner lower end, may be caught by the fastener. Absent.
In addition, since the outer ends of the side wall-shaped support portions formed on the left and right are bent to the left and right to form a guide portion that is wider than the plate pressure, the outer wall plate that is lowered from above for mounting The risk of damaging the lower end is eliminated.

  The “wide” is preferably about 5 mm, but is not limited to this value as long as a corner exterior plate can be attached under the above conditions.

  Further, “bent to the left and right” means that the shape is bent, and other processing methods such as brazing are also included in the claims.

The invention described in claim 4
The nail hole is formed at a position 14 mm or more below the upper side of the attachment part,
The central screw hole is a fastening member for an outer wall plate, which is located within 3 mm from the center of a substantially rectangular diagonal line connecting the upper and lower ends of the left and right side walls of the left and right support portions.

  In the invention of this claim, since the position of the nail hole is used more than 14.5 mm from the upper side of the mounting portion, even if the pushing force acts upward for some reason during the work, the fastener is not It becomes difficult to peel off.

Further, since the position of the central screw hole is at or near the center of the contact surface between the fastener and the base material, the screw can be easily screwed and the stability after screwing is increased.

The device according to claim 5 is:
The horizontal part of the left and right side wall-shaped support parts that protrudes inward from the lower part of the horizontal part or the upper and lower parts of the horizontal part by processing, and constrains the lower surface of the horizontal part or the lower and upper surfaces from both the left and right sides. The outer wall plate fastening bracket according to any one of claims 1 to 4, wherein a part restraining mechanism is formed.

  In the device of this claim, the horizontal portion restraining mechanism can be easily formed.

  In addition, the horizontal portion support mechanism projects a part of the portion located below the horizontal portion of the left and right side wall-shaped support portions to the inside by cutting and bending, and restrains only the lower surface of the horizontal portion from both the left and right sides ( (Support).

  The fastener of the present invention can be used to install the outer wall plate of many manufacturers with only one kind, so the worker of the outer wall plate installation work can Since there is no need to arrange and store fasteners suitable for each installation location, the labor and cost for that are eliminated. In addition, since there is no risk of bringing an incorrect manufacturer-standard fastener to the work site, the burden required for management and the like is reduced from this aspect as well.

  In addition, even if the outer wall plate has an upper portion with an inclination toward the outside, and the upper portion is narrow, the downward bent portion is formed by a step or an inclined portion on the lower surface and the base material side. Since the dent is a structure that fits the narrowed upper part of the outer wall plate well, the horizontal part of the fastener can fix the upper part of such an outer wall plate below it more reliably. Become.

It is a figure which shows the shape of the fastener of 1st Embodiment of this invention. Similarly, it is a figure which shows the dimension of the horizontal part outer side vicinity. Similarly, it is a figure which shows a mode that the product of the manufacturer of each outer wall board is being fixed. Similarly, it is a figure which shows a mode that the lowermost outer wall board is attached. Similarly, it is a figure which shows a mode that the outer wall board for corner | angular parts is attached. It is a 3rd view of the fastener of the 2nd Embodiment of this invention. It is a 3rd page figure of the fastener of the 3rd Embodiment of this invention. It is a figure which shows the structure of the principal part of the fastener of 4th Embodiment of this invention.

  Hereinafter, the present invention will be described based on the best mode. In addition, this invention is not limited to the following embodiment, Of course, the requirements described in the claims and the scope equivalent thereto are all included in the scope of rights.

(First embodiment)
FIG. 1 shows the dimensions and shape of the outer shape of the fastener according to the first embodiment of the present invention, and FIG. 2 shows the dimensions of the main part. In both figures, 10 is a mounting portion, 11 is its base plate portion, 12 is its nail hole portion, 18 is a nail hole, and 19 is a screw hole. 20L and 20R are left and right support parts, 21L and 21R are apexes thereof, 22L and 22R are guide parts thereof, and 23L and 23R are side walls thereof. Reference numeral 30 denotes a horizontal portion, 31L and 31R are outwardly obliquely bent portions, and 32 is a downwardly bent portion.

  (1) in FIG. 1 uses this fastener (which is often referred to as a ventilation clasp to distinguish it from a metal fitting that does not exist) because it has a ventilation portion between the building base material and the outer wall plate as the base material for the outer wall of the building. It is the figure which looked at the attached state from the outside (front) direction orthogonal to a base material. (2) The figure is also a view seen from the right side, and the same is seen from the left side. (3) is the figure which looked at the lower part from the upper part similarly. However, since it is self-explanatory and complicated, mounting screws and nails, building base materials, etc. are not drawn.

The manufacture of the fastener of the present embodiment is mainly performed by pressing, cutting, and bending of a metal thin plate. Specifically, a thin metal plate having a thickness of about 1.0 mm, such as a galvanized steel plate, is first formed into a thin plate piece of a predetermined shape by pressing and cutting, and then the thin plate piece is bent. Specifically, the left and right sides of the mounting portion 10 (substrate portion 11) are bent 90 degrees forward to form the left and right support portions 20R and 20L, and the lower portion of the mounting portion 10 is the same as the left and right support portions 20R and 20L. The horizontal portion 30 is formed by bending 90 degrees in the (front) direction, and further, the left and right sides of the tip thereof are bent obliquely upward and outward to form bent portions 31L and 31R that are obliquely upward and outward, and the central portion is also 90 degrees downward. The bent portion 32 is formed by bending it. It goes without saying that the right and left sides may be bent downward and the central part may be bent outward and obliquely upward.

  As shown in FIG. 1, this fastener has a width (horizontal direction) of 58 mm, a height (vertical direction) of 53.8 mm, and a thickness (front-rear direction) of 22.9 mm.

  Further, the three nail holes 18 are 14.5 mm below the upper side of the mounting portion 10. For this reason, even if a push-up force acts upward for some reason during the work, the fastener is difficult to peel off.

Further, as easily understood from FIG. 1 (1), a line connecting the left and right upper and lower ends of the left and right support portions 20R and 20L, that is, the convex portion of the contact portion with the base material of the fastener. The line connecting the portions forms a substantially rectangular shape, and one of the three screw holes 19 at the center is close to the center position 0 of the diagonal line of the rectangle (position within 3 mm). As a result, when the screw is screwed into the middle screw hole, the fastener becomes difficult to rotate, fixing at that time is facilitated, and stability after screwing is increased.

  FIG. 2 is an enlarged view of the vicinity of the outside of the horizontal portion of (2) in FIG. As shown in the figure, the horizontal portion 30 protrudes outward from the outer ends of the left and right support portions 20R, 20L by 7.9 mm, and a downward bent portion 32 is formed at the tip of the horizontal portion 30 by bending. The lower end is located 7.2 mm below the upper surface (left side in the figure) of the horizontal portion on the base material side.

In addition, the bent part to the lower side is the tip of the part where the left and right side parts or the center part on the tip side of the horizontal part is stepped by being bent downward and then bent horizontally, and then bent further horizontally. The starting position of the step is 4.1 mm from the outer end of the portion that forms the vertical direction of the support part, and the tip side is positioned about 1.1 mm below by the step. Further, the surface on the base material side of the portion bent downward by 90 degrees is located at a position 6.9 mm from the outer end of the portion that forms the vertical direction of the support portion, and the outer surface of the portion that forms the vertical direction of the support portion. The position is 7.9 mm from the outer end, and the lower end is 7.2 mm from the upper surface of the horizontal portion.

In addition, the left and right sides of the tip of the horizontal portion 30 are bent diagonally upward by about 68 degrees from the position of 4.0 mm from the outer ends of the left and right support portions 20R and 20L (which forms an inclination of 22 degrees with respect to the vertical line). Bending portions 31L and 31R that are 7.0 mm long and obliquely upward are formed. It should be noted that the outer ends of the outwardly bent portions 31L and 31R do not protrude outward (forward) from the outer end of the downward bent portion 32.

  The side walls 23L and 23R of the left and right support portions 20R and 20L form horizontal apex portions 21L and 21R having a length of 5.388 mm at the upper ends, and the outer ends thereof form a circular arc with a radius of 22.5 mm from above to below. Finally, the guiding portions 22L and 22R that are vertical are formed while drawing. Thereby, the lower end surface of the outer wall plate inserted from above in the mounting operation of the exterior plate at the site is appropriately mounted. This will be described later with reference to another drawing. Moreover, the outer side edge part of the side wall parts 23L and 23R is each bent right and left. For this reason, the width | variety of the contact location with the outer wall board | plate of guidance part 22L, 22R becomes wider than 5 mm and 1 mm of board thickness, and there is no possibility of damaging an outer wall board | plate with a sharp front-end | tip.

  The lower ends of the side wall portions 23L, 23R of the left and right support portions 20R, 20L are also the lower ends of the fasteners, and their positions are at a distance of 14.5 mm from the back surface of the horizontal portion 30. For this reason, although this is also demonstrated later, this fastener can be used for fixation of the outermost wall plate of the lowest step. Incidentally, in the conventional one, the horizontal portion is formed approximately in the middle.

  FIG. 3 shows a state in which the fasteners of the present embodiment fix the outer wall plates of the respective manufacturers arranged above and below. In the figure, reference numeral 1 denotes a fastener according to the present embodiment, 31 is a bent portion obliquely upward to the outside, and 91U, 91L to 95U, 95L are upper (U) lower (L) outer walls of each manufacturer. It is a board. (1) in this figure is the case where the outer wall plate to be attached is a 15 mm and 16 mm thick product of Nichiha Corporation's 16 mm thickness product, and (2) is the case of Kanjima Chemical Industry Co., Ltd. Yes, (3) is also the case of 15 mm thick product of Asahi Tostem Exterior Co., Ltd. (4) is the case of 15 mm thickness product of Kubota Matsushita Exterior Co., Ltd. (5) This is also the case for a 16 mm thick product from Kubota Matsushita Exterior Co., Ltd.

In any outer wall plate of any manufacturer, the base material (rear) direction is constrained by the vertical part of the outside (anti-base material direction) end of the side wall parts 23L and 23R, and the upper part is slightly lower due to the step or inclination of the horizontal part 30 And is restrained by the lower surface of the front end side (outer side, front side), downward is restrained by the upper step of the upper side surface of the horizontal portion 30 or the upper end surface of the outer wall plate, and the lower end is outward. It can be seen that the upper ends are constrained by the downward bent portions 32 at the outwardly bent portions 31L and 31R.
Furthermore, in the case of the outer wall plate that is narrowed by forming an inclination at the upper end shown in (1) to (3), it can be seen that the restraint is further ensured because it is restrained even at the step.

The scales (1) to (5) in this figure are the same except for the thickness (2). Further, the fastener 1 is not shown except for the main part for fixing the outer wall plate of each manufacturer. Furthermore, the base material etc. are also omitted.
Further, there is a ventilation (air) space between the surface of the base material and the inner surface of the outer wall plate.

Next, workability will be described.
As shown in (1) to (5) of FIG. 3, each manufacturer's outer wall plate has a complicated step at its lower end, but the upper ends of the left and right side wall portions 23L, 23R are 5.388 mm or less. In addition, since the guide portions 22L and 22R are continuously formed, the lower end of the outer wall plate inserted from above in the mounting work of the exterior plate in the field, in particular, the inner end thereof is the side wall portions 23L and 23R. It does not catch on the upper end, and does not catch on the upper ends of the bent portions 31, 31L, 31R that are obliquely upward and outward, and is guided so as to be properly fitted.

  FIG. 4 shows a state where the lower end of the lowermost outer wall plate is attached. This figure is the case of Nichiha Co., Ltd. shown in (1) of FIG. 3, and the lower end of the fastener 1 of this embodiment, that is, the lower ends of the left and right support portions 20R, 20L is the front (left side in the figure). It exists in the substantially same height as the lower end of the outer wall board which exists in. For this reason, even if it does not use the fastening metal fitting for a lower end, a big clearance gap does not arise between the lower end of the outer wall board after attachment, the foundation below it, etc.

FIG. 5 shows a state in which an elongated plate-like outer wall plate having a cross-section “<(the angle between two sides is 90 degrees)” used for the corner of the building is attached. This figure is a case where the bottom is seen from the top. In this figure, 96 is an outer wall board for a corner of a building. The outer wall plate 96 is bent 90 degrees at the center, and the horizontal length (inside dimension) of the bent inner surface is 70 mm and the thickness is 15 mm.
Also in this case, it can be seen that the two fasteners 1 appropriately fix the outer wall plate bent at a right angle.

(Second Embodiment)
FIG. 6 shows a trihedral view of the fastener according to the second embodiment. (1), (2) and (3) in this figure have the same meaning as in FIG. In this figure, 25L and 25R are horizontal part restraining mechanisms. This is because a part of the portion located below the horizontal portion 30 of the left and right side wall-like support portions 23L and 23R is protruded inward by cutting and bending, and the horizontal portion is restrained from both the left and right sides of the lower surface (particularly , Support from below).

(Third embodiment)
In FIG. 7, the 3rd view of the fastener of 3rd Embodiment is shown. (1), (2) and (3) in this figure have the same meaning as in FIG. In this figure, 26L and 26R are horizontal upper restraint mechanisms, and 27L and 27R are horizontal lower restraint mechanisms. This is because part of the portions located below and above the horizontal part 30 of the left and right side wall-like support parts 23L, 23R are projected inward by forming a recess by cutting and pressing, and the horizontal part is Restraining from the left and right sides of the lower surface.

(Fourth embodiment)
In FIG. 8, the structure of the principal part of the fastener of 4th Embodiment is shown. (1), (2) and (3) in this figure have the same meaning as in FIG. This clasp is a clasp without a ventilation portion between the base material of the building and the outer wall plate (for this reason, it may be simply referred to as a metal fitting or a clasp. However, a recess is formed on the base material side. This is the case.)

As shown in this figure, this fastener has a length of 50 mm in the front-rear direction of the side wall-shaped support portions 20L and 20R formed on the left and right of the attachment portion to the base material, and the horizontal cross-sectional shape is also “L”. "" Type instead of "" type.
Further, the present embodiment is different from the previous embodiments in that the overall height is 45 mm in order to ensure the strength while reducing the weight. In addition, since the height of the entire fastener is reduced, the distance between the nail hole 18 and the upper end of the fastener is less than 14 mm, and the horizontal portion at the upper end of the side wall-like support portion is also eliminated. Note that the upper end of the support portion is combined with a cutting process in order to have a roundness, but it is not shown because it has a complicated drawing and a well-known shape.

  The same applies to the bent portions 31R and 31L that are obliquely upward and outward, the bent portions 32 that are downward, and the steps. In addition, the horizontal restraint is not drawn because it is complicated.

  The present invention can be used in the construction industry, particularly in the housing exterior industry.
