Description

TECHNICAL FIELD The present invention relates to an exterior panel having ribs that look different depending on the angle of incidence of light and the angle at which a person sees them, and which have a high degree of design.

Conventionally, inorganic boards such as ceramic siding boards, slag gypsum boards, and metal siding boards, fiberboards such as particle boards, and resin boards are used as exterior wall boards for constructing the exterior walls of buildings. When an exterior wall is installed using exterior wall panels, a plurality of exterior wall panels are joined together in the vertical and horizontal directions.

When these exterior wall panels are manufactured, as described in Patent Document 1, after extruding a base material, texture is often applied to the surface of the exterior panel by embossing with a roller. .

However, in terms of production, the raw sheet immediately after extrusion had bulges due to pressure release. If a linear bulge occurs in a specific part of the outer wall panel in the direction of extrusion, the bulging part will appear as a line due to the influence of light reflection after the panel is actually installed on the outer wall, resulting in a design problem for the outer wall. was occurring.

Preferably, the direction in which the rising inclination angle of the rib continuously changes is different from left to right for each horizontal joint, and the rib is attached to the outer wall for use.

In the outer wall panel according to the present invention, ribs having rough projecting surfaces that diffusely reflect light and smooth side surfaces that reflect light are arranged vertically and horizontally. Because the light changes continuously as it travels, when the light hits the siding, the area of the protruding surface or side of the rib that reflects or diffuses the reflection changes gradually in the horizontal direction, creating a gradation pattern on the surface of the siding. As a result, it is possible to enhance the design and make the vertical lines that inevitably appear in the manufacturing process less conspicuous.

In addition, since the ribs are arranged so that the bottom joints formed between the laterally adjacent ribs and the horizontal joints formed between the vertically adjacent ribs are aligned, the overall feeling of unity is achieved. It can be a certain outer wall, and substitutability can be improved when dividing the outer wall plate and attaching it to the outer wall.

In addition, since the bulging portion, which is thicker than the water bottom joint, is provided so as to be continuous at the upper and lower ends of the bottom joint and the horizontal joint when viewed from the front, the strength in the vertical direction can be increased.

Exterior panel 1 according to the present invention will be described in detail below with reference to the drawings.

[Embodiment]
FIG. 1 is a front view showing an exterior wall panel 1 according to the present invention. The outer wall panel 1 is mainly used for outer walls of general buildings such as ordinary houses, shops, and public facilities. The outer wall plate 1 has a rough pattern on the surface of the base plate 1a. As shown in FIG. 1, the rough pattern consists of 3 rib groups 1b each having 40 ribs 2 arranged in the horizontal direction. A horizontal joint 3 formed between vertically adjacent rib groups 1b and a bottom joint 4 formed between horizontally adjacent ribs 2 are provided so as to form a straight line. As will be described later in the examples, by forming the outer wall plate 1 in a straight line, substitutability can be enhanced when attaching to the outer wall when the outer wall plate 1 is divided. The number of ribs 2 arranged vertically and horizontally can be changed as needed.

The outer wall plate 1 is used by being divided at a horizontal joint 3 and installed along the outer wall of the building. In this embodiment, the length of the outer wall plate 1 in the width direction is 1 m, but the length in the width direction is appropriately cut at intervals of 250 mm according to the length of the outer wall so as not to leave any excess. be able to.

(About hollow hole 5)
FIG. 2 shows a horizontal sectional view of the outer panel 1. As shown in FIG. The outer wall plate 1 is formed by extrusion molding, and as shown in FIG. 2(a), the inside of the substrate 1a has hollow holes 5 at regular intervals. The hollow holes 5 consist of four large hollow holes 5a and one small hollow hole 5b, which are continuous at intervals of about 250 mm.

By providing the hollow holes 5, the strength of the outer wall plate 1 itself can be increased. When cutting the outer wall plate 1 vertically according to the width of the outer wall, cut the outer wall plate 1 vertically along the bottom joint 4 above the small hollow hole 5b. By making the hollow holes 5 small hollow holes 5b at regular intervals, it is possible to reduce the hollow portions in the cross section of the outer wall plate 1 when cut, compared to cutting along the large hollow holes 5a. It can have a flat cross section.

Since the hollow portion of the small hollow holes 5b has a smaller volume than the large hollow holes 5a, the bottom joint 4 above the small hollow holes 5a swells after extrusion molding, as shown in FIG. 2(a). Therefore, as shown in FIG. 4, when light hits the outer wall plate 1, the bulging portion corresponding to the upper portion of the small hollow hole 5a appears as a vertical line L due to light reflection.

(About rib 2)
Ribs 2 are formed on the surface of the outer wall plate 1, and bottom joints 4 are formed between the ribs 2 adjacent in the horizontal direction. The surface of the bottom joint 4 is embossed to have fine unevenness, and the surface has rough unevenness to diffusely reflect light.

The rib 2 is a short-circuit-shaped block, and has a projecting surface 2a projecting from the substrate 1a, one longitudinal inclined surface 2b, the other longitudinal inclined surface 2c, an upper end surface 2d, and a lower end surface 2e. there is

Further, as shown in FIG. 2(b), the protruding surface 2a of the rib 2 is embossed to have fine unevenness, which is a rough surface and diffusely reflects light. Also, one longitudinal inclined surface 2b and the other longitudinal inclined surface 2c of the rib 2 are smooth and reflect light.

Further, as shown in FIGS. 3(a) and 3(b), the rising inclination angles θ1 to θ40 formed by the substrate 1a and one longitudinal inclined surface 2b of the rib 2 change continuously in the horizontal direction. . That is, the rising inclination angles θ1 to θ40 gradually decrease as the rib 2 goes from left to right. In this embodiment, the rising inclination angle θ1 of the leftmost rib 2 is 70 degrees, and the rising inclination angle θ40 of the rightmost rib 2 is 30 degrees. .theta. gradually changes by about a little over 1 degree as the rib 2 shifts by one in the horizontal direction. On the other hand, the rising inclination angle formed by the substrate 1a and the other longitudinal inclination 2c is fixed at 70 degrees for any rib 2. FIG.

Since the height of the rib 2 and the rising inclination angle of the other longitudinal inclined surface 2c side are uniformly formed at 70 degrees, by sequentially changing the rising inclination angles θ1 to θ40 of the rib 2, the protruding surface 2a and The area of one longitudinal inclined surface 2b also changes. That is, when the rising inclination angle θ1 is 30 degrees, the area of the projecting surface 2a is large and the area of one longitudinal inclined surface 2b is small, but when the rising inclination angle θ40 is 70 degrees, the area of the projecting surface 2a is small. , and the area of one longitudinal inclined surface 2b is increased. Therefore, since the rising inclination angles θ1 to θ40 gradually decrease from left to right, the area of the projecting surface 2a gradually decreases from left to right when the outer wall plate 1 is viewed from the front. , and the area of one longitudinal inclined surface 2b seems to gradually increase.

Therefore, since the protruding surface 2a diffusely reflects light and the one longitudinal inclined surface 2b reflects light, as shown in FIG. A gradation pattern in which the area that reflects or diffusely reflects light and the area of the shadow gradually change in the horizontal direction can be provided, and the design of the outer wall of the building can be enhanced.

In addition, for a person who walks while looking at the outer wall, the angle at which the outer wall is viewed changes as the person walks. The appearance of shadows, expressions, and gradation patterns are also different, and you can enjoy the design of the outer wall.

(Regarding horizontal joint 3)
As shown in FIG. 5 and the like, the horizontal joints 3 formed between the rib 2 and the rib 2 vertically adjacent thereto are formed so as to form a straight line in the horizontal direction.

(Regarding bottom joint 4)
As shown in FIG. 5 and the like, bottom joints 4 formed between ribs 2 and adjacent ribs 2 are formed so as to form a straight line in the vertical direction. The surface of the bottom joint 4 has fine unevenness by embossing so as to diffusely reflect light.

(Regarding the filling portion 6)
As shown in FIG. 5 , the fill portion 6 is provided so as to be continuous at the upper and lower ends of the bottom joint 4 and the horizontal joint 3 . By providing the thicker portion 6 than the bottom joint 4 of the outer wall plate 1, the strength of the outer wall in the vertical direction can be increased.

Moreover, as shown in FIGS. 6 and 7, not only the horizontal joint 3 but also the portion other than the horizontal joint 3 may be provided with the filling portion 6 at the bottom joint 4 at a constant interval d1. By providing the raised portions 6 at a constant interval d1, compared with the case where the raised portions 6 are provided only on the horizontal joints 3, the exterior wall of the building can be given a sense of unity and the design can be enhanced. In addition, when the angle of the sunlight is large, the horizontal striped pattern appears with shadows, and the connection in the horizontal direction can be felt. In addition, it is possible to use a large exterior wall pattern with different facial expressions depending on the time of day.

As shown in FIG. 7, when the fill portion 6 is provided in the horizontal joint 3, the fill portion 6 is thick so that it is continuous from end to end of the outer wall plate 1. When the bottom joint 4 is provided with the filling portion 6, it is provided independently without being continuous.

As shown in the cross-sectional views of FIGS. 8(a) and 8(b), the bottom joint 4 is provided with a bulging portion 6 at a constant interval d1, rising from the bottom joint 4 at angles θa and θb and having a height of about 1 mm. is. In this embodiment, the distance d1 is 50 mm, and the angles θa and θb are each 60 degrees, but they can be changed as appropriate.

(Regarding groove surface 7)
When the exterior wall panel 1 is manufactured, since the ribs 2 have different sizes on the left and right sides, depending on the extrusion speed of the base material, the height of the horizontal joints 3 may be disturbed and the design may be impaired. Therefore, as shown in FIGS. 7 and 9, groove surfaces 7 extending from the longitudinal upper end surface 2d and the lower end surface 2e of the rib 2 to the horizontal joint 2 are provided in the direction toward the substrate 1a. By providing the groove surface 7, a dark shadow can be formed in the center of the horizontal joint 3 when looking at the outer wall plate 1, and even if the height of the horizontal joint 3 is shifted, the dark shadow is conspicuous. Height deviation can be made inconspicuous.

Further, by providing deep shadows in the horizontal joints 3, the contrast of the shadows can be further enhanced in the exterior wall panel 1 as a whole, and an exterior wall with a high design property can be obtained.

[Example]
When the outer wall plate 1 is used for the outer wall, rib groups 1b obtained by dividing the outer wall plate 1 at each horizontal joint 3 are attached to the outer wall. The horizontal length in the width direction of the rib group 1b is the same even after division. On the other hand, since the vertical length of the rib group 1b is determined by the length of the rib 2 in the longitudinal direction, there are several types of rib groups 1b having different vertical lengths.

When actually used for the outer wall of a building, as shown in FIGS. 10 and 11, the rib group 1b with different lengths in the longitudinal direction is vertically inverted and attached to the outer wall so as to form a gradation pattern alternately left and right. . Therefore, the direction in which the rising inclination angle of the rib 2 continuously changes differs for each horizontal joint 3, and the rib 2 is attached to the outer wall and used.

Since the rising inclination angles θ1 to θ40 of the rib group 1b gradually change, the outer wall plate 1 when viewed from the front is left-right asymmetrical. By enforcing it, the vertical line L due to the bulge does not appear to be continuously connected vertically. Further, since the gradation pattern of the rib group 1b is highly designed, the vertical lines L are not conspicuous. When the vertical line L becomes inconspicuous, the visibility of the vertical line L itself can be lowered by dispersing the places where the line of sight of the person viewing the outer wall is concentrated.

Since the length of the rib 2 in the longitudinal direction is changed for each horizontal joint 3 of the outer wall plate 1, when the outer wall plate 1 is divided, the rib groups 1b having different vertical lengths can be formed. Therefore, since the rib group 1b is attached at the site, by randomly attaching the rib group 1b, the outer wall can be made by combining the rib groups 1b with various patterns having different vertical lengths depending on the site.

When a plurality of outer wall boards 1 are divided and mounted, even if the rib group 1b of another outer wall board 1 is mistaken for mounting, the bottom joint 4 and the horizontal joint 3 of the outer wall board 1 are aligned. Therefore, after installation, the outer wall can be formed with the horizontal joints 3 and the bottom joints 4 aligned. Therefore, the outer wall panel 1 has high substitutability.

In addition, since the angle of incidence of light changes depending on the season and the time of day, the shadows on the outer wall differ when the angle of incidence changes, and various gradation patterns can be achieved.

Further, as shown in FIG. 12, depending on where the person H walking in front of the building sees the outer wall, the area of the ribs 2 reflecting and the area of diffuse reflection differ.

When the person H on the side where the inclination angle gradually changes, that is, on the left side in FIG. Since the area of the protruding surface 2a that diffusely reflects light is on the front side, it looks large in perspective, and the change in gradation can be clearly recognized.

When the person H in the center looks at the outer wall plate 1, the area of the protruding surface 2a of the rib 2 that diffusely reflects the light appears to be the largest compared to the others, so the pattern looks darker gradation.

When a person H on the side where the rising inclination angle is fixed, that is, on the right side in FIG. Since the projecting surface 2a that diffusely reflects light becomes smaller in order from the back side to the front side, a gradation pattern that becomes brighter from the back side to the front side is obtained.

In this manner, the expression of the gradation pattern of the outer wall plate 1 differs depending on the angle at which the person H views the rib group 1b. When a person walks in the horizontal direction with respect to the outer wall plate 1, he/she can enjoy the change of the shadow of the outer wall like a hologram.

In addition to the high designability, for example, if the outer wall board 1 is used for the outer wall of a store, by combining rib groups 1b with different horizontal and vertical lengths, even simple alphabets and characters can be displayed. For example, shadows can be made to appear as symbol marks of the store. Therefore, even a person away from the store can find the symbol mark appearing on the outer wall, and the outer wall panel 1 can exhibit not only the design but also the advertising function of the store. .

[Other embodiments]
The rising inclination angles θ1 to θ40 change by more than 1 degree each time the rib 2 shifts by one, but the rising inclination angles θ1 to θ40 may change so that the degree of change gradually increases.

In addition, the rising inclination angles θ1 to θ40 change continuously from one direction, but if the gradation pattern is left-right asymmetrical, the vertical line L becomes inconspicuous, so it changes continuously from both directions. may

Since the exterior wall panel of the present invention has ribs on the surface of which the rising inclination angle gradually changes in the horizontal direction, a hologram gradation pattern can be formed, which is useful for building exterior wall materials and the like.
