Abstract

PROBLEM TO BE SOLVED: To remove a pattern by hammering when the top of a pattern on a building board is above the nail head when fixing with nailing, and the color, gloss, and color change of repair paint applied to that part Avoid detracting from aesthetics due to differences.
SOLUTION: When a building board 1 having a ridge pattern formed on the surface thereof is fastened by nailing, the interval between the tops 3 of the ridge pattern of the portion into which the nail 2 is driven is made narrower than the diameter of the nail head 4. As a result, the nail head 4 is put on the top 3 of the ridge pattern, and the hammer for driving the nail 2 is hit only by the nail head 4 to prevent the pattern chipping.

Description

  The present invention relates to a building board for buildings.

  Conventionally, a building board such as a wall board or an eaves-back ceiling board is fastened to a structural material by nailing.

  In the above construction, generally a drill hole is drilled in a building board according to the arrangement pitch of the structural material, and a nail is driven using a nailing machine, but in order to drive completely, it is continuously driven with a hammer. .

  In the case of such nailing, if the concavo-convex pattern is provided on the surface of the building board, the concavo-convex pattern may be chipped by hitting the concavo-convex pattern with a hammer when nailing. The nail head is coated with repair paint of a color similar to that of the board, but if a hammer chip occurs, the repair paint needs to be applied to the chipped portion of the building board.

  In recent years, building boards are often painted in multiple colors, but the repair paint is usually a single color, and the gloss is different from the painting applied to the building boards. If the paint repair is about the area of the nail head, it will not stand out so much, but if it is applied to the chipped part with a hammer, the area will become wider and noticeable. Moreover, since the discoloration resistance color with the aging differs between the paint applied to the building board and the repair paint, this defect is promoted.

On the other hand, Patent Document 1 discloses a technique for minimizing the impact of hitting by providing a convex portion with a certain area in the surface pattern of the exterior plate and receiving a hammer hit by that portion. It has been done. However, the entire convex portion of the surface handle is hit with a hammer, which widens the failure range of damage. In addition, providing the portion having a certain area that is hit by the hammer in the ridge pattern itself greatly restricts the pattern design.
JP-A-7-247621

  The present invention has been made in view of the above situation, and an object of the present invention is to provide a building board in which a protruding pattern is less likely to be chipped when a protruding board is fastened to a building structural material by nailing. It is said.

  In order to achieve the above object, the present invention provides a building board having a ridge pattern formed on the surface thereof, and the interval between the tops of the ridge pattern at least in the surface portion where the nail is driven is larger than the diameter of the nail head. It is narrowed.

  Further, the present invention is characterized in that the ridge pattern formed on the surface portion into which the nail is driven has a band shape, and is formed within a range where the band-shaped portion is at least in contact with the structural material.

  With the above configuration, the top of the ridge pattern receives the nail head, and the hammer can be hit only by the nail head, so that the entire surface of the ridge pattern is not damaged, and repair paint is applied after nailing. There is an advantage that only the head part is formed and the area is small and unnoticeable.

  The building board according to the present invention has a ridge pattern on the surface, and in the place where the nail corresponding to the pitch of the structural material is driven, the distance between the tops of the ridge pattern is narrower than the diameter of the nail head. In this case, the nail head is covered on the ridge pattern, and the hammer hits only the nail head and does not hit the ridge pattern.

  FIG. 1 shows an embodiment according to the present invention, and is an explanatory view showing a cross section in a state in which a nail (2) is driven into a building board (1). In the figure, symbol (3) indicates the top of the ridge pattern on the surface of the building board, and (4) indicates the nail head.

  As shown in the figure, in the building board (1), the interval between the tops (3) of the ridge pattern is narrower than the diameter of the nail head (4). For this reason, the nail head (4) is covered with the top (3) of the ridge pattern, thereby preventing the top (3) of the ridge pattern from being chipped by hammering.

  FIG. 2 is an explanatory view showing a comparative example with the present invention. This figure shows a cross section when a nail is struck in a portion where the distance between the top portions (6) of the ridge pattern is wider than the diameter of the nail head (4). In this case, there is a problem that the portion above the nail head (4) is hit by a hammer and the top (6) of the ridge pattern is missing.

  In this respect, in the building board (1) of the present invention, the hammer can be hit by the nail head (4), so that the top (3) of the ridge pattern is not damaged.

  In addition, in the building board (1) according to the present invention, the nail head (4) may be covered with the tops (3) of the two ridge patterns, or the tops (3) of the two or more ridge patterns may be covered. It may be a mode of covering.

  Further, in the building board (1) according to the present invention, it is desirable that the convex top portion (3) receiving the nail head (4) is substantially the same height on both sides of the nail head (4). .

  FIG. 3 is an explanatory view perspectively showing a construction structure according to the second embodiment of the present invention. In the illustrated form, it is preferable that nails are driven into the building board (1) between adjacent ridges.

  In FIG. 3, reference numeral (5) denotes a structural material, a portion of the surface of the building board (1) where the narrow strips are concentrated to form a belt-like aspect, and a structural material (5) for driving a nail Are in the relationship shown in the figure.

  This building board (1) is formed at a position where the strip-like portions having a narrow interval are concentrated to form a belt-like aspect, and are in contact with the structural material (5). When the nail is driven into the nail, it is preferable to hit the nail at any position of the portion where the narrow strips are concentrated to form a belt-like aspect. Thereby, it can nail to a structural material (3) reliably.

  In addition, by making the space between the tops (3) of the ridge pattern of the portion into which the nail is driven in this way, it is possible to obtain a building board in which the nail-punched portion is not noticeable without generating a pattern chipping due to hammering. Can be provided.

It is explanatory drawing which shows Example 1 concerning this invention. 6 is an explanatory diagram illustrating a comparative example of Example 1. FIG. It is explanatory drawing which shows Example 2 of this invention.
