Description

[Technical Field]

[0001] The present invention relates to a bearing wall member and a structural facing. [Background technology]

[0002] In some wooden buildings, structural panels are attached to a base frame as a load-bearing wall. The structural panels are fixed to a frame by nailing. Nails must be driven into the base frame from the surface of the structural panel at predetermined intervals from the periphery of the structural panel. Therefore, it is necessary to accurately mark the nailing positions on the structural panel. Conventionally, the nailing positions have been indicated by marking the surface of the structural panel. However, marking each structural panel requires a lot of time and effort. Therefore, in recent years, vertical guide lines to guide the nailing positions have been printed on the surface of the structural panel in advance. As shown in Figure 4, the nailing positions are indicated by vertical guide lines 51, 51 on both side edges of panel 50 and a vertical guide line 52 in the widthwise middle. In Figure 4, 53 indicates the base frame. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-77572 Summary of the Invention [Problem to be solved by the invention]

[0004] When conventional structural paneling is attached to a frame and then exposed to rain, water can seep in through the edge of the structural paneling, causing rain stains at the bottom end, which can be noticeable and make the panel look unsightly.

[0005] The present invention was conceived from this perspective, and its object is to provide a bearing wall member and a structural surface material that can make rain stains less noticeable. [Means for solving the problem]

[0006] The first invention for solving the above problem is a load-bearing wall member comprising a structural panel and a base frame to which the structural panel is nailed, characterized in that a dark band portion that is darker in color than the panel is formed at the lower edge of the structural panel, and nailing lines indicating the intervals between nails are formed in the dark band portion. According to the load-bearing wall member of the present invention, the dark-colored band formed on the lower edge makes rain stains less noticeable. In addition, the nailing lines can guide the nailing positions and make rain stains even less noticeable.

[0007] In the shear wall member of the present invention, nailing position guides for guiding the nailing positions are preferably formed on the surface of the structural panel, and the nailing position guides preferably include vertical side edge guide lines extending along the side edges on both the left and right sides of the panel, vertical intermediate guide lines extending up and down in the widthwise middle, and a plurality of auxiliary vertical guide lines arranged at predetermined intervals in the widthwise direction between the vertical side edge guide lines and the vertical intermediate guide lines. With this configuration, the auxiliary vertical guide lines are arranged at close intervals between the vertical side edge guide lines and the vertical intermediate guide lines, so that even if the panel is cut into small pieces, the vertical guide lines remain, allowing the nailing positions to be guided.

[0008] In the shear wall member of the present invention, it is preferable that the nailing lines of the dark band portion are formed on the extensions of the intermediate guide vertical line and the auxiliary guide vertical line, respectively. With this configuration, it is possible to guide the nailing position over the entire height of the structural surface member.

[0009] In the bearing wall member of the present invention, the nailing lines of the dark colored bands are preferably formed in a grid pattern extending vertically and horizontally, so that the grid pattern makes rain stains less noticeable.

[0010] In the bearing wall member of the present invention, it is preferable that the dark color band is also formed on the upper edge of the structural panel. With this configuration, the structural panel can be installed regardless of the top or bottom.

[0011] In the bearing wall member of the present invention, it is preferable that the nail driving position guide is made of a color different from the color of the nails to be used. With this configuration, it is easy to visually check the nails driven into the nail driving position guide, making it easy to check for missed nails.

[0012] The second invention for solving the above problem is a structural panel that is nailed to a base frame, characterized in that the lower edge of the panel has a dark band that is darker in color than the panel, and nailing lines indicating the intervals at which nails should be driven are formed in the dark band. According to the structural surface material of the present invention, as in claim 1, even if rain stains occur, they can be made less noticeable by the dark colored band portion, and the nailing lines can guide the nailing positions. [Effects of the Invention]

[0013] According to the load-bearing wall member and structural surface material of the present invention, the dark colored band portion can make rain stains less noticeable, and the nailing lines can guide the nailing positions. [Brief explanation of the drawings]

[Figure 2] 1 is an exploded perspective view showing a bearing wall member according to an embodiment of the present invention. [Figure 3] FIG. 10 is a front view showing a load-bearing wall member according to a modified embodiment of the present invention. [Figure 4] FIG. 1 is a front view showing a conventional load-bearing wall member. DETAILED DESCRIPTION OF THE INVENTION

[0015] A bearing wall member and a structural surface material according to an embodiment of the present invention will be described in detail with reference to the drawings. In the description, the same elements are given the same reference numerals, and duplicated explanations will be omitted. The bearing wall member of the present invention can be applied to, for example, a general wall with a wall ratio of 3 to 11, or a high-strength wall with a wall ratio of 30. In this embodiment, the load-bearing wall member and the structural surface material will be described using an example in which the base frame comprises a frame-shaped outer peripheral frame and an intermediate vertical frame provided inside the outer peripheral frame.

[0016] As shown in Figures 1 and 2, the bearing wall member 1 comprises a structural panel 10 and a base frame 30. The structural panel 10 has a rectangular shape when viewed from the front, with dimensions of, for example, a width of 910 mm and a height of 2650 mm. The height is set appropriately depending on the floor height. The structural panel 10 is made of particle board and is 9 mm thick in this embodiment, which is a typical wall. In the case of a high-strength wall, the thickness is 12 mm.

[0017] As shown in FIG. 2, the base frame 30 is to which the structural panel 10 is fixed by nailing. It is configured with a frame-shaped outer peripheral frame 31 and an intermediate vertical frame 32 on the inside for each structural panel 10. The outer peripheral frame 31 includes an upper horizontal frame 33, a lower horizontal frame 34, and side vertical frames 35 on both the left and right sides. The side edges of adjacent structural panel 10 are fixed to the side vertical frames 35. In this embodiment, which is a wall for a residential building constructed using a wood-frame construction method, each frame is made of structural lumber for wood-frame construction, for example, 204 (38 mm x 89 mm) or 206 (38 mm x 140 mm). For walls of large facilities, for example, laminated lumber with a dimension of 406 (89 mm x 140 mm) is used.

[0018] As shown in Figures 1 and 2, the structural surface material 10 is formed with a dark color band 11 and nailing position guides 12. The dark color band 11 is painted a color darker than the surface material, making rain stains less noticeable. The dark color band 11 is, for example, red, darker than the color of the wood on the surface of the surface material. The color of the dark color band 11 is not limited to red, as long as it is darker than the surface material and different from the color of the nails 2. The dark color band 11 may also be formed by printing. The dark color band 11 is formed on both the upper and lower ends of the structural surface material 10, and has a predetermined height (for example, approximately 320 mm). The upper and lower dark color bands 11 are formed with the same height. Nail driving lines 13 are formed on the dark color band 11. The nail driving lines 13 indicate the nailing intervals and are formed as white without being painted. The nailing lines 13 are arranged, for example, at 100 mm intervals, and are formed in a grid pattern extending up, down, left, and right. In the lower dark band portion 11, of the nailing lines 13 extending horizontally, the lowest nailing line 13 is configured to be positioned at the nailing height of the lower horizontal frame 34. The nailing lines 13 extending horizontally in the lower dark band portion 11 are arranged at 100 mm intervals above the lowest nailing line 13.

[0019] The nail driving position guide 12 is a guide for the nail driving position and is written or printed on the surface of the face material. The nail driving position guide 12 includes a side edge guide vertical line 15, a middle guide vertical line 16, and a reserve guide vertical line 17.

[0020] The side edge guide vertical lines 15 are used to guide the nailing positions of the nails 2 that secure the side edges of the structural panel 10 to the side vertical frames 35, and are composed of dashed lines extending vertically along the side edges on both the left and right sides of the panel. The side edge guide vertical lines 15 are formed between the upper and lower dark bands 11, 11. The dashed lines are, for example, 100 mm long and spaced 100 mm apart. The nailing positions are at both ends of the dashed lines, spaced 100 mm apart along the side edges of the panel. In the upper and lower dark bands 11, nails 2 are driven at 100 mm intervals using the nailing lines 13 as a reference. Note that pointed nailing points may be illustrated aligned with the ends of the dashed lines.

[0021] The intermediate vertical guide line 16 is used to guide the nailing positions of the nails 2 that secure the widthwise intermediate portion of the structural panel 10 to the intermediate vertical frame 32. It is composed of a dashed line extending vertically in the widthwise intermediate portion of the panel. The intermediate vertical guide line is formed between the upper and lower dark-colored bands 11, 11. The dashed line is, for example, 90 mm long and spaced 10 mm apart. The intermediate vertical guide line 16 is formed on the same line as the vertical nailing lines 13 in the widthwise intermediate portion of the dark-colored band 11. The nailing positions are every third end of the dashed line, spaced 200 mm apart along the side edge of the panel. In the upper and lower dark-colored bands 11, nailing points may be illustrated to align with every third end of the dashed line.

[0022] The auxiliary vertical guide lines 17 are used to guide the nailing position when the structural panel 10 is cut and the side edge vertical guide lines 15 and intermediate vertical guide lines 16 are removed. A plurality of auxiliary vertical guide lines 17 are arranged at predetermined intervals in the width direction between the side edge vertical guide lines 15 and the intermediate vertical guide lines 16. The auxiliary vertical guide lines 17 are arranged at 100 mm intervals from the intermediate vertical guide line 16 side, and are formed on the same line as the vertical nailing lines 13 of the dark color band portion 11. The auxiliary vertical guide lines 19 are composed of dashed lines extending in the vertical direction. Like the side edge vertical guide lines 15, the dashed lines are, for example, 100 mm long and spaced 100 mm apart.

[0023] As shown in FIG. 1, when nails 2 are driven to secure the upper edge of the structural panel 10 to the upper horizontal frame 33, they are driven in the middle between the nailing lines 13 extending vertically on the upper dark band 11. The height position of the nailing is a position corresponding to the upper horizontal frame 33 (in this embodiment, it is on the uppermost nailing line 13 of the nailing lines 13 extending horizontally). Note that in the embodiment shown in FIG. 1, the nails are driven in the middle between the vertically extending nailing lines 13, but this is not limited to this. Nails may also be driven in the vertically extending nailing lines 13, i.e., at the intersection of the uppermost horizontally extending nailing line 13 and the vertically extending nailing line 13.

[0024] When driving nails 2 to secure the lower edge of the structural panel 10 to the lower horizontal frame 34, they are driven in the middle between the vertically extending nailing lines 13 of the lower dark band 11, just as they were for the upper edge. The height position of the nailing is a position corresponding to the lower horizontal frame 34 (in this embodiment, the nailing is on the lowest nailing line 13 of the horizontally extending nailing lines 13). Note that in the embodiment shown in FIG. 1, the nails are driven in the middle between the vertically extending nailing lines 13, but this is not limited to this. Nails may also be driven in the vertically extending nailing lines 13, i.e., at the intersection of the lowest horizontally extending nailing line 13 and the vertically extending nailing line 13.

[0025] The effects of the shear wall member 1 and structural panel 10 of this embodiment are described below. According to the shear wall member 1 and structural panel 10 of the present invention, the formation of a dark color band 11 at the lower edge of the panel makes rain stains less noticeable. This prevents the structural panel 10 from losing its aesthetic appeal. Furthermore, the formation of nailing lines 13 in the dark color band 11 makes it possible to guide the nailing position using the dark color band 11. Furthermore, the nailing lines 13 make rain stains even less noticeable.

[0026] The surface of the structural panel 10 is formed with nailing position guides 12, each of which includes a side edge guide line 15, a middle guide line 16, and a preliminary guide line 17. This means that the guide lines are distributed across the entire width of the panel. In contrast, as shown in FIG. 4, a conventional structural panel 50 has only a side edge guide line 51 and a middle guide line 52. The large spacing between the guide lines causes the guide lines to disappear when the panel is cut, making it impossible to guide the nailing positions. In this embodiment, the preliminary guide line 17 remains even when the structural panel 10 is cut into small pieces, allowing the nailing positions to be guided. If the preliminary guide line 17 is not located at the left or right side edge of the cut structural panel 10 (if the panel is cut at an intermediate position), the nailing positions are determined by referring to the nearest preliminary guide line 17.

[0027] Furthermore, the nailing lines 13 in the dark color band portion 11 are formed on the extensions of the intermediate vertical guide lines 16 and the auxiliary vertical guide lines 17, respectively, and therefore can guide the nailing positions even at the upper and lower edge portions of the structural surface panel 10. In other words, the nailing lines 13 can guide the nailing positions over the entire height of the structural surface panel 10. Furthermore, the nailing lines 13 are formed in a grid pattern, and this grid pattern makes rain stains even less noticeable.

[0028] Furthermore, since the dark band portion 11 is formed on both the lower edge and the upper edge of the structural panel 10, the structural panel 10 can be installed regardless of the top-bottom direction, making it easy to handle during installation.

[0029] The nail driving position guide 12 is formed in a color different from the color of the nails 2 to be used, so that it is easy to visually check the nails 2 driven into the nail driving position guide 12. This makes it easy to check if any nails 2 have been left behind.

[0030] FIG. 3 shows a front view of a modified shear wall member 1. This shear wall member 1 is used for high-strength walls with a large wall ratio. The structural surface member 10 is made of, for example, 12 mm thick particle board, and the base frame 30 is made of, for example, 406-type (89 mm x 140 mm) laminated lumber. The modified shear wall member 1 has more nails 2 than the embodiment shown in FIG. 1. Specifically, the nails 2 are driven along the outer edge of the structural surface member 10 at a pitch of 50 mm, half the pitch of the embodiment shown in FIG. 1. When driving nails 2 along the vertical side edge guide lines 15, the nailing positions are at both ends and the middle of the dashed lines of the vertical side edge guide lines 15, and at the middle of the gap between the lines, and the nails 2 are driven at 50 mm intervals along the side edges of the surface member. When nails 2 are driven along the upper and lower edges of the structural panel 10, the nailing positions are on the nailing lines 13 extending up and down the dark band 11 and in the middle between adjacent nailing lines 13, 13, and nails 2 are driven at 50 mm intervals along the upper and lower edges of the panel. The nailing height position corresponds to the upper horizontal frame 33 or the lower horizontal frame 34. The other components including the nail driving guide 12 are the same as those in the above embodiment, so the same reference numerals are used and the description thereof will be omitted.

[0031] While the present invention has been described above as an embodiment, it is not limited to the above embodiment, and various design changes are possible without departing from the spirit of the present invention. For example, in the above embodiment, only one intermediate vertical guide line 16 is provided, but if the width of the face plate is large and the number of intermediate vertical frames 32 of the base frame 30 is multiple, the number of intermediate vertical guide lines 16 can be increased in accordance with the number of intermediate vertical frames 32.

[0032] In the above embodiment, the dark color bands 11 are provided on both the upper and lower edges of the structural panel 10, but this is not limitative and they may be provided at least on the lower edge. In this case, the side edge guide vertical lines 15, the intermediate guide vertical lines 16, and the auxiliary guide vertical lines 17 are formed to extend to the upper end of the panel.

[0033] Furthermore, in the above embodiment, the nailing positions of the nails 2 for fixing the upper edge of the structural panel 10 to the upper horizontal frame 33 and the nails 2 for fixing the lower edge to the lower horizontal frame 34 are determined in accordance with the nailing lines 13 in the dark band portion 11, but the nailing positions may also be illustrated in advance in the dark band portion 11 along the horizontal direction.
