2. Description of the Related Art Architectural boards such as decorative outer wall panels fastened to outer wall surfaces of houses and the like are designed in consideration of designability and the like.
Usually, as shown in FIG. 5 and FIG. 6, it is fastened to the base material 70 on the building frame side by using the fastener 30. Generally, the fastener 30 includes a substrate 31, a horizontal piece 32 erected on the substrate 31, and upper and lower locking pieces 33A and 33B formed at the tip of the horizontal piece 32, and a real part is formed in four turns. Each of the building boards 40A and 40B has a locking portion 33
A, 33B locks up and down (see, for example, JP-A-9-203184).

Normally, as shown in the figure, the fastener 30 has upper and lower ends of a substrate 31 having inclined surfaces 31a and 31b inclined obliquely backward, and an upper end of the upper inclined portion 31a has a horizontal portion 31c. A screw hole 34 for attaching the fastener 30 to the base material 70 is formed therein. Since this kind of the fastener 30 is attached to a base material 70 of a building which is, for example, a horizontal waistline or a vertical waistline, since it has the slope parts 31a and 31b, as shown in FIG. A space S, which is a gap H, is formed between the space and the building board 40, and this space S is effectively used as a ventilation path or a drainage path in case rainwater enters.

The examples shown in FIGS. 5 and 6 are for the case where the building board is stretched horizontally, but when the building board is stretched vertically,
A fastener having a shape as shown in FIG. 7 is used. The fastening 130 includes a substrate 131, a vertical piece 132 erected on the substrate 131, and left and right locking pieces 133 </ b> A and 133 </ b> B formed at the tip of the vertical piece 132. Substrate 13
The upper and lower ends of 1 are rising pieces 131a, 131b
And each tip is a horizontal portion 131c. Even in this case, since the fastening pieces 130a and 131b have the rising pieces 131a and 131b, when the fastener 130 is attached to a base material of a building, a space S which is a gap H as shown in FIG. 6 is formed.

Further, the upper and lower ends of the building board 40 fastened as shown in FIG. In order to prevent infiltration of rainwater and secure the appearance of the hang portion, an appropriate decorative member such as a parting edge is attached to the eave portion and a base drainage fitting is attached to the base portion. 8 and 9 show a construction example of the eaves sky (FIG. 8) and a construction example of the base (FIG. 9). In the construction of the eaves top, a substrate 51 fastened to a base material (vertical edge in this example) 70 of the building
A receiving plate 52 extending forward from an upper end of the substrate 51;
A parting edge 50 consisting of a front plate 53 extending downward from the front end of the receiving plate 52 and covering the upper end surface of the building board 40 is attached so as to cover the upper end edge of the building board 40. As described above, in the fastening of the building board using the fastening hardware 30, since the gap H is formed between the base material 70 and the building board 40, the gap H is filled. It is necessary to insert a long packing material 80 between the substrate 51 and the base material (vertical trunk edge) 70.

[0006] The same applies to the construction of the base portion, and a substrate 61 fastened to a base material (horizontal edge in this example) 71 of the building.
A base drainage bracket 60, which extends obliquely downward from the lower end of the substrate 61 and has a vent 62 formed on the lower surface side, is attached so as to cover the lower edge of the building board 40. Also in this case, in order to fill the gap H, the substrate 61 of the base drainage fitting 60 and the base material (horizontal body edge) are used.
It is necessary to insert a long packing material 80 between the first and second packings 71.

[0007]

As described above, in the fastening work of a building board using a fastener, the eaves and the base, which are the upper and lower ends of the fastened building board, are constructed as follows. Cosmetic parts (parts such as parting edges, base drainers)
In addition, a packing material of a required thickness is required, and it takes time and effort to prepare the packing material, and it is required to strike a decorative member in a state where the packing material is sandwiched at the time of construction, which makes it difficult to work with the packing material. . Furthermore, the presence of the long packing material may impair the ventilation on the back side of the building board.

[0008] Further, the parting edge and the substrate part of the base drainage bracket are usually flat surfaces, and a gap is likely to be formed between the front plate of the decorative member and the surface of the building board after the striking work, from which rainwater may enter. It can happen. On the other hand, if the size of the decorative member is extremely close to the thickness of the building board so that no gap is generated, it is not easy to assemble the decorative member on the building board and the air permeability is impaired at this time. May be a factor. The same applies to the construction of the overhang portion.

[0009] From these circumstances, conventionally, in the construction of the eaves heaven portion, the base portion, or the overhang portion, a special decorative member (a parting edge having a different shape, a base drainage fitting,
By preparing in advance a squid head corner, etc., the easiness of construction, the prevention of water leakage, and the securing of air permeability have been achieved. The object of the present invention has been made in view of the above circumstances, and in fastening work of a building board, it is possible to construct an eaves ceiling, a base or an overhang without using a packing material, Another object of the present invention is to provide a decorative member for a building board which does not hinder drainage and air permeability even if the same form is used for the construction.

According to the present invention, there is provided a decorative member for a building board according to the present invention, comprising: a substrate fixed to a base material of a building; a receiving plate extending forward from a lower end of the substrate; A front plate extending from the front end of the receiving plate in a state parallel to the substrate so as to cover an end surface of the building plate. A plurality of ribs are formed, and a ridge projecting toward the front plate side is formed near the upper end of the substrate.

[0011] In the decorative member for building boards according to the present invention,
The height of the ribs and the height of the ridges are determined by a gap H formed between the ground side and the back of the building board when the building board is fastened using a fastener. It is a distance that can be covered only by. For this reason, the decorative member can be firmly fixed to the base material side without the need to arrange the packing material as in the conventional construction method. Further, only the decorative member for building boards exists in the gap H, and since there is no long packing material, the air permeability is not hindered.

Further, the building board is brought into a posture in which the front surface thereof is pressed against the front plate while the rear surface side thereof is pressed forward by the ridge formed near the upper end of the substrate. For this reason, the front panel of the decorative member and the front of the building board are in close contact with each other, which reliably prevents infiltration of rainwater, and a space is formed between the back of the building board and the board, so that air permeability is improved. Is also secured. In addition, as described above, regardless of the direction and direction of the decorative member, airtightness between the front plate and the front of the building board and air permeability between the back surface of the building board and the board are simultaneously secured. The decorative member for a building board according to the present invention can be effectively used as a decorative member common to an eaves section, a base section, or an overhang section.

[0013] In a preferred embodiment, the receiving plate of the decorative member has a step, and an opening for ventilation or water passage is formed in each step. Thereby, between the end face of the building board and the receiving plate, the air permeability between the end face of the building board and the base material is further ensured, the occurrence of dew condensation is suppressed, and when rainwater enters. Also, it will be easily discharged.

In a preferred aspect, the substrate of the decorative member further includes an extension extending outside the receiving plate portion. When the decorative member for a building board of this shape is used as a parting edge, it is possible to attach the extension piece to the base material in a posture in which the extension piece is in contact with the eave heaven material. Rainwater can be reliably prevented from entering through the gap with the heavenly material. In addition, the decorative member for building boards according to the present invention can be similarly applied regardless of whether the building board is vertical or horizontal. Depending on which one, only the length of the decorative member is adjusted. [Detailed description of the invention]
