Description of the Related Art As an exterior work of a building, a ceramic building board 40 having a form as shown in FIG. (For example, see Japanese Patent Application Laid-Open No. 2000-291225).
FIG. 5 shows an example of the fastening member.
Reference numeral 0 denotes a substrate 21 formed by punching from a stainless steel plate and sheet metal processing, and serving as a surface to be attached to a vertical member.
Two rising pieces 22 in the vertical direction having a height h formed by bending both ends of the substrate 21 in the horizontal direction by approximately 90 °;
23, and a horizontal rising piece 26 having a height H located between the two vertical rising pieces 22 and 23. The tip of the rising piece 26 in the horizontal direction is longer than the tip of the rising pieces 22 and 23 in the vertical direction by a distance X (H−
h), three locking projections 26a, 26b, 26c bent in opposite directions are formed at the tip of the horizontal rising piece 26. A through hole 28 for fixing is formed in the substrate 21. [0003] In order to fasten the building board 40, FIG.
As shown in FIG.
To fix the fastener 20 (in this example,
The particle board 60 is used as a base material, and a waterproof sheet 53 is further provided thereon. However, the base material may be omitted.) Then, the fixed fastener 20 is fixed. The building board 40 is fastened to a state where the solid mounting portion 42 on the back side, which is the lower horizontal side of the building board 40, is hooked to the upward locking pieces 26a, 26c formed on the horizontal rising piece 26 of FIG. wear. Thereafter, the downward locking piece 26b formed on the horizontal rising piece 26 of the other fastener 20 is locked to the lower solid mounting portion 44, which is the upper horizontal side of the building board 40, and Screws and nails 6 in the same manner
The required number is fixed to the vertical members 12 using 2 or the like. Thereby, the fastening of one building board 40 is completed. Hereinafter, the building board 40 is sequentially fastened while repeating the same operation. [0004] As shown in FIG. 7, since the fastening fitting 20 is covered from the outside by the fastening building board 40, a high appearance design is maintained after the fastening. Also, a waterproof sheet 53 constructed on the particle board 60
The space S defined by the height h of the vertical rising pieces 22 and 23 of the fastener 20 is provided on the surface of
c is formed, and that portion functions as an air passage, and it is possible to suppress the occurrence of dew condensation on the back surface of the building board 40. Even if it is generated, dew condensation water is discharged downward through the space. This prevents the back of the building board from being kept wet. [0005] As described above, in the construction method of fastening the building board 40 to the skeleton side by using the fastening members 20, the fastening members 20 are vertically erected at predetermined intervals. It is a natural premise that it is fixed to 12. On the other hand, in place of a structural plywood or a particle board as a base material, plate materials 51 and 52 as shown in FIG. 3 are stacked so as to be oblique to each other and assembled in a cross-girder shape. A plate thickness of about 9 mm and a plate width of about 55 mm, and two plate members are joined by an adhesive) may be used as a substitute for the structural face material. When using such a wooden substrate 50,
It is sufficient to fix the fastener to the plate member 51 located on the front surface, and it is not always necessary to fix the fastener to the vertical member 12, and the degree of freedom in selecting the fastening position increases. Specifically, the fastener can be fixed without worrying about the position of the vertical member 12. This is because the thickness of the vertical waist edge conventionally used for fixing the fastener is about 18 mm, and the thickness of 18 mm can be secured by overlapping two plate members 51 and 52 constituting the wooden base 50. Therefore, the fastening of the building plate to the plate member 51 can be sufficiently performed. However, as shown in FIG. 3, such a wooden substrate 50 naturally has a considerably wide space formed between the oblique plate members 51 and 52. Therefore, when the conventional fastener 20 is used, a situation may occur in which the fastener 20 must be located in the space. In such a case, the fastener 20 is naturally fixed to the plate 51 located nearby, but the predetermined attachment position of the fastener to the building board is changed, and Attachment (especially
In terms of wind resistance), there is a possibility that it becomes slightly unstable. The present invention has been made in view of the above circumstances, and has an area where nails or screws can be nailed, such as a wooden girder base, and an area where nails or screws can be nailed, such as a space. A construction that can always be stuck and fixed in a stable state without selecting a place, even on a wooden base where there are areas that cannot be mixed, thereby enabling the building boards to be securely fastened An object of the present invention is to provide a fastener for a board. According to the present invention, there is provided a fastener for solving the above-mentioned problems, comprising: a substrate; two vertically rising pieces provided on both ends of the substrate in the left-right direction; A horizontal rising piece located between the two vertical rising pieces, and a tip of the horizontal rising piece projects forward from a tip of the vertical rising piece, and a locking projection is provided there. It is characterized in that it has at least a fastening portion on which a piece is formed, and an attachment portion to a skeleton side extending laterally from both left and right ends of the board of the fastening portion. In this fastener, the area which can be used for fixing to the frame using nails or screws is the area of the board at the fastening portion and extends laterally from both left and right ends of the board. This is the area that includes the mounting part. Therefore, even in the case of a wooden base where the area where nails and screws can be nailed and the area where nails and screws cannot be nailed such as space are mixed in the lateral direction, When the fastener is placed at an arbitrary place without selecting a place, either one or two of the area of the board of the fastened part or the attachment part extending laterally from both left and right ends of the board. There is a very high possibility that the abutment will come into contact with the area where the nail or screw can be driven. Therefore, the fastening of the fastener to the wooden substrate is always stable, and as a result, the fastening of the building board is also stable. In the fastener according to the present invention, the whole may be made of one metal plate, and the fastening part and the mounting part are formed as separate members, and the two parts are integrated by an appropriate means such as welding. You may make it.
The left and right attachment portions are formed integrally and continuously on both sides of the second substrate, and the second substrate and the substrate of the fastening portion are integrally fixed by means such as welding or caulking.
