(Description of an embodiment of a decorative board material according to the present invention)
FIG. 1 is a schematic cross-sectional view showing an embodiment in which a decorative board material according to the present invention is attached to a building frame, and FIG. 2 is a schematic cross-sectional view showing a structure of a single decorative board material shown in FIG. FIG. 3 is a schematic cross-sectional view showing a holding metal fitting provided in the building frame, and FIG. 4 is a schematic front view of the holding metal fitting.

  As shown in FIG. 1, a decorative board material 10 according to the present invention has a substantially rectangular cross section used for windbreak provided at the end of a roof of a house, and is perpendicular to the longitudinal direction, that is, the paper surface of FIG. 1. It is a plate-like member that is long in any direction. The front surface 12 side of the decorative board material 10 is directed to the outdoor 14 side, the rear surface 16 side of the decorative board material 10 is arranged to face the building housing 18 side, and is attached to the building housing 18 by screwing.

  Below, the decorative board | plate material 10 attached to the building frame 18 is demonstrated, referring FIG. 1 and FIG. A decorative surface 20 as a decorative part is provided on the surface 12 side of the decorative board material 10, and a stripe pattern is formed on the decorative surface 20 by a plurality of irregularities formed so as to extend in the longitudinal direction, that is, the direction perpendicular to the paper surface of FIG. Designed to give the shadows of However, the present invention is not limited to this, and any other design can be used as long as the appearance of the house is established, as long as it is simply colored or painted on the decorative surface. Further, the contour of the decorative material may be a surface that is slightly inclined so as to be retracted toward the building housing 18 as it goes down, and may be advantageous for draining rainwater that falls on the surface 12.

  Here, the decorative board material 10 is configured as a cement-based extruded product having an equal cross section in the longitudinal direction, that is, the direction perpendicular to the paper surface of FIG. In addition, it is not limited to cement-based, can be used any other material including resin-based material, but when using a cement-based extrusion molded body having a feeling of weight compared to the resin-based material, The effect of the present invention is more embodied. Examples of the dimensions of the decorative board material 10 include a length of 3 m in the longitudinal direction, a height of 15 cm in the vertical direction, and a thickness of about 2 cm, but other arbitrary dimensions can be used.

  On the upper side of the decorative surface 20, a first protruding rib 24 protruding from the surface 12 toward the outdoor 14 side is provided, and on the side of the housing from the outdoor side end of the first protruding rib 24 above the first protruding rib 24. The screwing part 22 is provided at the position of FIG. 2, and the second protruding rib 26 protruding from the surface 12 toward the outdoor 14 side is provided above the screwing part 22. In this case, the screw striking portion 22 needs to have a concave groove shape (see FIG. 2) so that the head 30 of the screw 28 attached does not protrude to the outdoor side from the outdoor side end portion of the protruding rib 24. The protruding ribs 24 and 26 may be formed so as to protrude from the decorative surface 20 to the outdoor 14 side by about 5 mm, for example. In addition, the screwing part 22 is a part into which a screw is simply driven, and it is not necessary to give special marking. However, when there is a possibility that the screwing position is erroneous as in the case of only the first protruding rib, a screw line or the like may be provided.

  In this way, by providing the first protruding rib 24 below the screw striking portion 22 and above the decorative surface 20, the head 30 of the screw 28 driven into the screw striking portion 22 is hidden by the first projecting rib 24. In addition to being invisible from the lower side, the design of the decorative surface 20 that is the external appearance is not impaired.

  The decorative board material 10 is fixed to the wood 32 extending from the building housing 18 side so as to face the back surface 16 side of the decorative board material 10 by a screw 28 driven into the screw driving portion 22. Here, on the outer wall 34 of the building housing 18 facing the back surface 16 of the decorative board member 10, two L-shaped cross-sectional portions that protrude in the horizontal direction from the outer wall 34 toward the outdoor 14 side and bend upward are provided in two upper and lower portions. A holding metal fitting 36 is provided as an engaging tool. For example, as shown in FIGS. 3 and 4, the holding metal fitting 36 is configured to include L-shaped bent portions 38 on the upper and lower sides of a substantially rectangular flat plate shape.

  Further, as shown in FIG. 2, on the back surface 16 side of the decorative board material 10, an inverted L-shaped key-like portion 40 (dent) as an engaged portion corresponds to the bent portion 38 of the holding metal fitting 36. As shown in FIG. Projecting portions 42 are formed on the lower sides of the upper and lower key-like portions 40 so as to come into contact with the building housing 18 side or the holding fitting 36 when the decorative board material 10 is attached.

  On the surface 12 side of the decorative board material 10, a metal keraba wrapping plate 44 (keraba drainer) covers the upper end of the building housing 18, extends horizontally and bends downwardly, and bends the second projecting ribs 26 and screws. It arrange | positions so that the front-end | tip of the 1st protrusion rib 24 of the lower part of the part 22 may be covered. Due to such a positional relationship, the first 24 and the second projecting ribs 26 restrain the horizontal displacement of the keraba wrapping plate 44 toward the building housing 18, so that the keraba wrapping plate 44 serves as a support member for preventing the blurring. Can function. Further, the first protruding rib 24 can block and hide the upper screw head 30 when the decorative member 10 after mounting is viewed from below. Therefore, the beauty of the decorative board material 10 is not impaired.

  On the other hand, by providing two protruding ribs on the upper side of the decorative surface 20 like the protruding ribs 24 and 26, it is possible to prevent damage to the protruding ribs during transportation. For example, in the case where the two decorative plate members 10 are turned upside down so that the protruding ribs of each of the decorative plates 10 are inward and are transported in a face-to-face manner through a thin sheet, the protruding ribs such as only the protruding ribs 24 are provided. In the case of transporting only one decorative board material 10, the two decorative board materials 10 facing each other are in a mode of supporting the load of the decorative board material 10 at the protruding ribs 24 located at both ends. This is because the load is concentrated in a single-point support state when focusing on one side where the projection ribs 24 are provided, and the projection ribs 24 are easily broken due to rocking or the like accompanying transportation.

  However, when the decorative board material 10 provided with the two protruding ribs 24 and 26 on the upper side of the decorative surface 20 is transported facing each other, the two sides of the decorative board material 10 are supported at two points by the two protruding ribs 24 and 26, respectively. Therefore, since the load is dispersed and the protrusion ribs 24 and 26 are not easily broken due to swinging or the like, the occurrence of breakage of the protrusion ribs 24 and 26 when the decorative board material 10 is transported can be reduced.

Thus, the decorative board material 10 is temporarily fixed to the building housing 18. Thus, the holding metal fitting 36 and the key-like part 40 are used to assist the screwing operation in the subsequent process. By doing so, it is not necessary to require a person who supports the decorative plate material 10 for positioning the decorative board material 10 in preparation for a screwing operation in a later process.

  After the temporary fixing, the screws 28 are driven at a predetermined interval with respect to the screw line in the longitudinal direction of the screw driving portion 22 to fix the decorative board material 10 to the wood 32 extending from the building housing 18. Thereby, the attachment work of the decorative board material 10 is completed. By doing so, it is possible to easily and efficiently attach the decorative board material 10 to the building frame 18. In particular, the time required for an operator to attach the decorative board material 10 to stay at a high place such as a roof is shortened, and a complicated work that requires cooperation of a plurality of persons can be avoided, so that work safety is also improved.

  In the above embodiment, a sheet metal screw, for example, can be used as the screw 28 to be driven into the screw driving portion 22. In addition, a pilot hole may be provided for the screw hitting portion 22 or a pilot hole may not be provided. Moreover, the holding metal fitting 36 provided in the building housing 18 may be a known catch-type metal fitting that is temporarily fixed by inserting the engaged portion of the decorative board material 10 into the holding metal fitting 36, and the screwing operation in the subsequent process can be easily performed. As long as the weight of the decorative board 10 can be temporarily placed on the building housing 18 side so as to be able to do so, not only the L-shaped holding metal fitting 36 but also any shape and structure can be used.
