Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building board and a construction structure thereof, and more particularly, to a building board having a high designability, which can give a different feeling depending on a viewing direction, and an outer wall portion and an outer corner of the building. The construction structure of the building board at the corner or corner.

[0002]

2. Description of the Related Art Generally, a building board as a building material is used as an exterior board (siding) on an outer wall portion of a building. Its external shape is almost a flat plate structure, and its surface portion expresses an uneven pattern shape (for example, brick tone and tile sticking) having convex portions divided by grooves (or joints). There are many. In addition, there are other types in which various three-dimensional uneven patterns are formed on the surface.

[0003] Originally, a building board is made as a plate-like body, so that its design evaluation naturally involves only the appearance viewed from the front. At that time, the grooves (or joints) are usually colored dark and the original purpose is to have a function as a drainage channel for rainwater. It is treated as a secondary part having a function to enhance the design exhibited by the convex part due to a shading effect contrasting with the convex part.

However, in reality, the exterior panel exhibits its design when attached to (or attached to) the outer wall of the building, so that the building after construction can be viewed from all directions. The appearance shape of the outer wall portion, the outer corner portion, or the inner corner portion of the building board or the building to which the building board is attached when the building board is attached needs to be naturally considered in the design evaluation.

[0005] In particular, in recent years, with the trend toward high-end products, exterior panels having a greater thickness than before have been manufactured. Has become. Under such a trend, the influence of each surface constituting the groove on the surface design has become much larger than before. For example, for an exterior plate in which the area ratio of the two slopes and the bottom surface constituting the groove to the total surface area is considerably larger than before, the design exhibited by the groove itself is no longer the same as the conventional secondary design. The effect on surface design has become so remarkable that it cannot be handled by conventional treatment.

[0006] By the way, the design evaluation of the building board is, after all, that the irradiation light such as natural light hits the building board surface.
It depends on the visual evaluation of the reflected light reflected therefrom, and there have already been some proposals for improving the design of the groove (or joint) from such a viewpoint. For example, Utility Model Registration No. 1998656
Japanese Utility Model Publication No. 3-34433 discloses a technique in which minute joints are formed by embossing in joints in order to make joints in joints inconspicuous.
No. 43840 proposes a method in which the grooves are provided with uneven protrusions of the aggregate by lysine coating, and furthermore, the protrusions are scraped off with a reverse roll so that only the grooves have an uneven pattern. . In addition, Japanese Patent Laid-Open
In Japanese Patent Application Laid-Open No. 7-247653 , the shape of the groove is a W-shape having a specific shape, and light incident at right angles to the wall surface (surface portion) of the building board is totally reflected in the W-shaped groove. 90
Light incident from directions other than ゜ is made to be semi-reflective or non-reflective from inside the W-shaped groove, so that the appearance of the decorative groove of the W-shaped groove is always changed with the change of the sunshine time. There has been known a method of obtaining a rich and highly designable architectural board.

[0007]

[Problems to be solved by the invention]

Each of the above proposals is effective, but in any case, when a parallel ray is projected from the surface to the surface of the building board, the light from the plurality of grooves formed on the building board surface is reduced. Even if the reflection state may be different between the vertical groove group and the horizontal groove group, at least in the groove group running in the same direction, it is equal, and the unevenness on one building board The reflection state of light in the shape pattern is changed as compared with the conventional one, and even if the design evaluation is high, it is still the same monotonous pattern anyway. Further, even when a large number of such architectural boards are constructed on the outer wall portion, the outer corner, or the inner corner of a building, the same pattern is repeated monotonously.

[0008] With the passage of the moon and within one day, in addition to the lighting direction changing every moment according to the operation of the sun, in addition to the fact that people look at the building from all directions, it is monotonous. It is preferable that one building board has a so-called random reflection condition that transcends a pattern, so that a building board with a rich design can be obtained that gives a different feeling depending on the viewing direction. The same is true even when a large number of building boards are constructed on the outer wall of the building, on the outside corner or on the inside corner, etc.By constructing the construction surface so that it has random reflection conditions as a whole,
It is possible to obtain a construction structure such as an outer wall portion, an outer corner portion, or an inner corner portion which is rich in a design that gives a different feeling depending on a viewing direction.

[0009] Accordingly, an object of the present invention is to provide a light reflecting condition of light from a surface portion in a single building board, or in an outer wall portion, an outgoing corner or an ingoing corner where a plurality of building boards are attached. Are partially different from each other, so that they are not monotonous repetition, but have a rich design that gives a different feeling depending on the viewing direction, as well as the outer wall, outer corner, or inner corner of the building. It is to provide a construction structure.

[0010]

According to the present invention, there is provided a building board comprising:
Basically, an architectural board having a plurality of grooves formed on a surface thereof, and a state of reflection of light from each groove when a parallel light beam is projected from the surface to the surface of the building board, The grooves are not equal, and at least one groove has a different reflection state from the other grooves, so that the reflection state from the surface portion is partially different. Features.

In this building board, at least one part of the surface of one building board has a part different in light reflection conditions from other parts, and a viewer can receive high design evaluation. In addition, different design feelings can be given depending on the viewing time and direction, thereby creating a unique design effect that has never been seen before. The concave groove may be either one along the longitudinal direction of the building board, one along the short direction, or both. Further, the concave groove may be any of a straight groove, a curved groove, and a groove in which a straight line and a curved line are formed continuously.

Preferably, each of the grooves has a first inclined surface, a second inclined surface, and a groove bottom connecting the lower ends of the first and second inclined surfaces. The inclined angle formed by the inclined surface 2 with the surface portion is different between the at least one groove having the different reflection state and the other groove, whereby the reflection state from the surface portion is partially changed. Are different.

Preferably, each groove has a first inclined surface, a second inclined surface, and a groove bottom portion connecting lower ends of the first and second inclined surfaces. An uneven pattern is formed on at least one of the inclined surface, the second inclined surface, and the bottom surface of the groove, and the uneven pattern formed on the at least one surface has at least one recess having a different reflection state. The groove is made different from the other concave grooves, so that the reflection state from the surface portion is made partially different.

Preferably, similarly to the above, each concave groove is formed of a first inclined surface, a second inclined surface, and a groove bottom portion connecting lower ends of the first and second inclined surfaces. An uneven pattern is formed on at least one of the first inclined surface, the second inclined surface, and the bottom surface of the groove, wherein the at least one surface on which the uneven pattern is formed has the reflection surface; At least one groove having a different state and another groove have different surfaces, so that the reflection state from the surface portion is partially different.

In the above case, the inclination angle formed by the first inclined surface with the surface portion in one concave groove and the inclined angle formed by the second inclined surface with the surface portion may be the same or different. You may. If they are different, there is an advantage that a higher design property is exhibited on the entire surface of the building board.
Further, the uneven pattern is arbitrary as long as it can visually appeal to what is seen, a pattern consisting of continuous or discontinuous concave or convex ridges formed along the concave groove, a small concave or It may be a pattern formed by repeating convex portions, a pattern formed by repeating step portions, or the like. Further, if one groove (or groove group) corresponding to the grooves having different reflection states is formed on the surface of one building board, the initial object can be achieved, A plurality (a plurality of groups) may be formed under different conditions. As a result, an architectural board with a better design can be obtained.

The present invention also discloses a construction structure in which any of the above-described building boards is attached to an outer wall portion, a corner portion, or a corner portion of a building. In this construction structure,
Each of the constructed building boards has at least one place and a place that reflects differently from the other parts, so that the entire outer wall part, the outer corner or the inner corner of the constructed building is formed. However, it gives the viewer a high design reputation. In addition, different design feelings can be given depending on the viewing time and the viewing direction, and a unique design effect that has not been obtained in the past can be obtained. When looking at the outer wall part, the outer corner or the inner corner of the constructed building as a whole, not as individual building boards, but at least one part of the whole as a reflection state different from other parts If it is formed, the construction structure can achieve the initial purpose.

According to the present invention for achieving the object,
The construction structure of the outer wall of the building, the outer corner or the inner corner,

Thus, the reflection state from the outer wall portion, the outer corner, or the inner corner is partially different.

In the construction structure, the at least one building board may be in a reflection state different from that of another building board. The aspect formed to have a reflection state different from the above may be diverted as it is for each building board. In addition, by constructing a group of building boards corresponding to the group of building boards having different reflection states by using a plurality of sets with different reflection conditions, it is possible to further enhance the design of the construction structure as a whole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a building board and its construction according to the present invention will be described below with reference to the drawings. The drawings are drawn only for the purpose of facilitating the understanding of the invention, and are characterized by only the grooves, particularly when the present invention is applied to a building board that is generally used as a building material. Is illustrated. Therefore, the overall size of the building board, the depth and width of each groove, the interval between each groove, and the shape of the convex part (for example, brick stacking or tile bonding) divided by the groove (or joint). Tonality) differs greatly from the case of actual building boards.

In the example shown in FIG. 1, the construction board 10 has a substantially flat plate appearance, and its surface portion 12 is provided with a large number of grooves 11 in the lateral direction (in the example shown, a concave groove is formed). Five grooves 11a to 11e) are formed. Each concave groove 11a
11e includes a first inclined surface L1 and a second inclined surface R1, and a groove bottom surface F connecting the lower ends of the first and second inclined surfaces L1 and R1. Groove width W
1. The width W2 and the groove depth h of the groove bottom surface F are made equal.

Furthermore, the first grooves 11a, 11b, 11d and 11e other than the groove 11c located at the center are used.
The angle formed by the inclined surface L1 with the surface portion 12 is θ1, and the angle formed by the second inclined surface R1 with the surface portion 12 is θ.
2 and θ1> θ2. On the other hand, in the case of the concave groove 11c located at the center, the angle between the first inclined surface L1 and the surface portion 12 is θ2, and the angle between the second inclined surface R1 and the surface portion 12 is θ1. I have.

That is, in this building board, of the five concave grooves 11a to 11e, the first and second inclined surfaces L1 and R1 of one concave groove 11c form the inclination angle (θ2 , Θ1) are different from the other grooves 11a, 11b, 11d,
The inclination angles (θ1, θ2) formed by the first and second inclined surfaces L1, R1 of the surface 11e and the surface portion 12 are different. Thereby, when the parallel rays are projected from the surface portion 12 side, the reflection state of the light from each of the concave grooves 11a to 11e is determined by the concave groove 11c and the concave grooves 11a, 11b, 11d, 11e.
In the part, the part is different, and as a result, it is possible to give the viewer an appearance shape that is not monotonous repetition but rich in design. Furthermore, the fact that the angles θ1 and θ2 formed by the first and second inclined surfaces L1 and R1 with the surface portion 12 are not the same makes it possible to give a different feeling depending on the viewing direction.

In this example, only one groove 11c is formed so as to have a different light reflection state from the other grooves, but two or more grooves are formed differently from the other grooves. You may form so that a state may differ. In addition, the angle relationship between θ1 and θ2 is reversed as a means for changing the light reflection state, but the concave grooves may be formed at completely different angles such as θ3 and θ4. Further, the angle formed by the first and second inclined surfaces L1 and R1 with the surface portion 12 may be different for each groove.

In the example shown in FIG. 2, the building board 20 has grooves formed on the surface portion 22 (grooves 21a to 21c) formed not in the short direction but in the long direction. Of the three concave grooves 21a to 21c, the inclination angles (θ2, θ1) formed by the first and second inclined surfaces L1 and R1 of the upper concave groove 21a with respect to the surface portion are located in the lower two stages. 1 in that the first and second inclined surfaces L1, R1 of the concave grooves 21b, 21c are different from the inclination angles (θ1, θ2) formed by the surface portions. ing. In this case, it is easily understood that the same visual effect as that of the building board 10 shown in FIG. 1 is exhibited.

Although not particularly shown, both the short groove 11 shown in FIG. 1 and the long groove 21 shown in FIG. 2 are formed on the surface of one building board, and In addition, an uneven pattern shape (for example, brick tone or tile sticking tone) having convex portions divided by concave grooves (or joint portions) may be developed. This makes it possible to easily obtain a visual effect that is greater than that of the building boards 10 and 20 shown in FIGS.

FIG. 3 conceptually shows a case where the building corner is constructed by using the building board 10 shown in FIG. 1, and FIG. 4 shows the building board shown in FIG. 20 conceptually shows a case where a projecting corner of a building is constructed by using No. 20.
In the corner that was constructed in this way, each of the constructed building boards will have at least one place, a part that reflects differently from the other parts, and the entire corner will be visible In addition, different design feelings can be given depending on the viewing time and direction, and a unique design effect that has never existed before can be obtained. In addition, such a design effect is not limited to the outer corner, even when the construction is performed at the inner corner and the wall,
Can be obtained as well.

FIG. 5 shows another embodiment of the building board according to the present invention. In this building board 30, four concave grooves 31a-3
Although the cross-sectional shapes of 1d are all substantially the same,
In the concave groove 31a and the concave groove 31c, fine convex stripes are formed as a pattern on the groove bottom surface F1, and the first and second inclined surfaces L1 and R1 are flat surfaces. On the other hand, in the concave groove 31b and the concave groove 31d, the groove bottom surface F and the first inclined surface L1 are flat surfaces, but fine convex stripes are formed as a pattern on the second inclined surface R2. .

In this building board 30, the grooves 30a to 31d
In the above, the positions of the surfaces on which the fine uneven pattern (fine ridges) are formed are made different, so that the concave groove 31a and the concave groove 31 are formed.
The light reflection state at c and the light reflection state at the concave groove 31b and the concave groove 31d are different from each other, whereby the light reflection state at the surface portion 32 of the building board 30 is partially different. Are formed.

FIG. 6 shows still another embodiment of the building board according to the present invention. This building board 40 also has four concave grooves 41a.
To 41d are substantially the same, the first inclined surface L1 and the groove bottom surface F are all flat surfaces, and a fine uneven pattern is formed only on the second inclined surface R2. I have. The fine uneven pattern formed on the second inclined surface R2 is a fine ridge running in the horizontal direction in the concave grooves 41a, 41b, 41d, and a fine ridge running in the vertical direction in the concave groove 41c. ing.

In this building board 40, the grooves 40a to 41d
In the above, the shape of the fine concavo-convex pattern (fine projection) formed in the concave groove is changed to the concave groove 41a, 41b, 41d and the concave groove 41c.
And the grooves 41a, 41b, 41
The reflection state of the light at d is different from the reflection state of the light at the concave groove 41c. Thereby, a place where the light reflection state is partially different is formed on the surface portion 42 of the building board 40.

Even with such building boards 30, 40,
It will be understood that, similarly to the building board shown in FIG. 1 or FIG. 2, the viewer can be given a design-like appearance that is not monotonous and repetitive. Further, the angles formed by the first and second inclined surfaces L1 and R1 (R2) with the surface portion 12 may be different or partially different,
It will also be understood that a higher design effect is thereby obtained. Further, the fine concavo-convex pattern is not limited to the fine convex streak as shown in the figure, and may be any shape such as a continuous or discontinuous step-like shape, a rib-like shape, a protrusion or a concave portion, and a ring-like shape.

FIG. 7 shows an example in which the technical concept according to the present invention is applied not to one building board but to the entire corner of the constructed building. here,
Two types of building boards 10a and 10b having different shapes of the concave grooves on the surface are joined at an angle of 90 degrees at the corner of the building. As can be understood by referring to the enlarged views showing the portions A and B in FIG. 7, all of the plurality of grooves 11A formed on one building board 10a have the same shape, and the first inclined surface L1 is formed.
Makes an angle θ1 with the surface portion 12a, and the second inclined surface R
The angle between 1 and the surface portion 12a is θ2, and
It is assumed that θ1> θ2. The plurality of grooves 11B formed on the other building board 10b also have the same shape,
The angle between the first inclined surface L1 and the surface portion 12a is θ2, and the angle between the second inclined surface R1 and the surface portion 12a is θ1. In the figure, only two building boards are shown, but in an actual building, two
Seed building boards are installed regularly or randomly.

In the construction structure at this corner, the building board 10a when parallel rays are projected from the surface to the building board surface portion
The state of reflection of light from the group and the state of reflection of light from the group of building boards 10b are the same for building boards in each group,
The group of building boards 10a and the group of building boards 10b are not the same. For this reason, the reflection state of the light at the projected corner portion is partially different, and a different design feeling can be given to the viewer as a whole viewed corner depending on the viewing time and direction. Such a design effect can be similarly obtained also in the construction structure in the corner portion and the wall portion, not limited to the corner portion.

In this construction structure, when making a group of architectural boards having different light reflection states, the construction boards shown in FIGS. It will be easily understood that the shape and the position of the fine unevenness formed on the slope and the bottom surface of the concave groove may be changed. In addition, a plurality of sets of building boards having different reflection states may be prepared with different reflection conditions, and these may be regularly or randomly attached and attached, thereby making the entire construction structure more rich in design. Things.

Further, although not particularly shown, the same type of building boards having grooves of different directions are attached and installed in one building board, or two or more kinds of grooves having grooves of different directions are installed. It is also possible to attach and build a building board to partially change the light reflection state. In addition, when a paint having a strong color rendering property is post-painted on the surface of the building board, the lighting direction of natural illumination light (sunlight) and the color temperature of the building in one day change, so that the groove (concave groove) is formed. The hue change can be more effectively exhibited by the shape and pattern applied to the surface, so that the design can be significantly changed to be displayed.
