Description

[0001]
【Technical field】
The present invention relates to a building board that is used by being attached to the outer wall of various buildings.
[0002]
[Prior art]
As shown in FIG. 8, a construction board 9 is known in which longitudinal grooves 91 and lateral grooves 92 are regularly arranged at regular intervals in a lattice pattern (Japanese Utility Model Publication No. 60-29560). A portion surrounded by the vertical concave groove 91 and the horizontal concave groove 92 becomes a convex surface 93, and the vertical concave groove 91 and the horizontal concave groove 92 become concave portions, and the role of draining rainwater by using the concave groove to flow downward. Is responsible.
The building board 9 is used by attaching a large number of the building plates 9 to the outer wall of the building, with the longitudinal direction being the horizontal direction and the short direction being the vertical direction (see FIG. 7 described later).
[0003]
[Problems to be solved]
However, in the building board 9, the longitudinal groove 91 provided in the short direction of the building board 9 extends straight from end to end of the building board 9.
For this reason, the cross-shaped intersection portions 94 of the lattice-like vertical concave grooves 91 and the horizontal concave grooves 92 are provided in the respective parts when carrying and transporting while holding the longitudinal direction of the building board 9 or when pasting to the building. For this reason, it was easy to break and a request for improvement was made in terms of work efficiency.
In addition, there is a problem that the horizontal concave groove 92 after construction is liable to collect dust and dust, and the building board 9 is soiled and the appearance is deteriorated at an early stage.
[0004]
Further, since the above-mentioned building plate 9 is provided with the vertical concave grooves 91 and the horizontal concave grooves 92 regularly, the vertical concave grooves 91 and the horizontal concave grooves are adjacent to each other in the installed state. If 92 does not penetrate in a straight line, the appearance of the building will be very bad.
For this reason, it is necessary to provide the vertical concave grooves 91 and the horizontal concave grooves 92 with high accuracy when the building board 9 is manufactured. Furthermore, it is necessary to arrange the vertical concave grooves 91 and the horizontal concave grooves 92 so that they are not displaced in the adjacent portions with great care during the construction.
[0005]
The present invention has been made in view of such conventional problems, and is intended to provide a building board that is easy to handle and construct and has excellent appearance after construction.
[0006]
[Means for solving problems]
According to one aspect of the present invention, a crossbeam for buildings plate is molded longer laterally, the surface is partitioned formed on upper and lower by one transverse groove, each section of the upper and lower the plurality of longitudinal grooves are formed, and the longitudinal groove formed in the longitudinal groove and a lower compartment which is formed in the upper compartment rather Do collinear longitudinal grooves and the transverse direction adjacent the The building board is characterized in that there are a plurality of widths in the lateral direction of the convex surface formed between the grooves .
[0007]
The upper and lower tiers are described with reference to the lateral groove. For example, as in the first embodiment, when there is only one lateral groove in the center of the building board, the lateral groove is used as a reference. One divided by is the upper row, the other is the lower row.
When there are a plurality of lateral grooves, attention is paid to a certain lateral groove, and when one of the adjacent portions through the lateral groove is an upper stage, the other adjacent is a lower stage.
[0008]
Next, the operation of the present invention will be described.
The building board according to the present invention is divided into an upper stage and a lower stage by lateral grooves, and a number of longitudinal grooves are provided in each of the upper stage and the lower stage. These longitudinal grooves are provided so that the upper stage and the lower stage are integrated so as not to form a groove penetrating in a straight line. That is, the vertical grooves are provided so that the positions of the vertical grooves in the upper and lower stages are different from each other (see FIG. 1 and the like).
[0009]
As described above, in the present invention, since there are almost no grooves penetrating the building board in the vertical direction, a significant reduction in strength in the vertical direction due to the groove formation is suppressed. Therefore, handling during transportation and construction becomes easy.
[0010]
Further, as shown in FIG. 7 described later, when the building board according to the present invention is applied to a building and rainwater falls on the building, as shown in FIG. After flowing down the groove, the flow reaches the horizontal groove, where it is distributed in the horizontal direction as shown by the arrow 8 in the figure, then descends into the lower vertical groove and further flows down. .
For this reason, even if dust or debris accumulates in the lateral groove, it is washed away when rainwater flows laterally. Therefore, it is difficult for the appearance to deteriorate due to dirt.
[0011]
In the present invention, since at least the longitudinal grooves are formed so as not to penetrate the building board in a straight line, as shown in FIG. , Misalignment of the vertical groove between the building boards is inconspicuous.
For this reason, positioning accuracy is not required during construction board construction, and construction is easy. In addition, in the formation of the longitudinal groove when manufacturing the building board, the groove width and the groove forming position are not required to be precise, and the manufacturing is easy.
[0012]
Moreover, the building board of the present invention is formed so that the upper and lower longitudinal grooves do not exist on a straight line. Therefore, in order to give the appearance impression that it is a natural stone, a calm design is formed, and an architectural board excellent in aesthetics can be obtained.
[0013]
As described above, according to the present invention, it is possible to provide a building board that is easy to handle and construct and has excellent appearance after construction.
[0014]
Examples of the building board according to the present invention include an inorganic cement board, a slate board, a calcium silicate board, a slag cement pearlite board, and the like.
Moreover, the building board concerning this invention can be utilized as an outer wall of various buildings.
[0015]
It is preferable as defined in claim 1, said building plate key next stick for buildings plate der that is formed long in the lateral direction (see FIG. 7). Thereby, despite the fact that many longitudinal grooves are formed, breakage can be made difficult to occur when carrying and carrying both ends. In addition, dust and the like in the lateral grooves can be washed away by many longitudinal grooves (see FIG. 6).
[0016]
A long-sided building board for horizontal application has a horizontal direction and is easy to break due to its long length. In particular, when a groove penetrating in the vertical direction is formed, this defect appears remarkably. Since the building board according to the present invention is not formed with a groove penetrating in the longitudinal direction, a decrease in the strength in the transverse direction due to the groove formation is suppressed, and the application to the building board long in the transverse direction functions very effectively.
[0017]
Then, as in the embodiment described in claim 2, it is preferred that the uneven pattern is formed on the surface of the protrusion between the longitudinal groove and the lateral groove adjacent said is provided. As a result, a natural stone-like appearance can be brought out, and when it is constructed as shown in FIG. 7 to be described later, the positional deviation of the longitudinal groove and the lateral groove in the adjacent building board can be made inconspicuous. it can.
[0018]
In addition, as shown in FIGS. 1 and 3 to be described later, the concavo-convex pattern has a structure in which a large number of laterally elongated recesses are provided, a pattern that appears to be thinly split like an iron slab, or a stucco pattern. Examples of the structure include a handle.
[0019]
Further, the lateral width of the convex portion surface Ri plurality of types Oh, certainly for the longitudinal grooves can be configured to not arranged in a straight line between the upper and lower, it is possible to reliably obtain such an effect in the present invention . In addition, when a large number of construction boards are installed adjacent to each other and the construction is performed, the longitudinal grooves are less noticeable, and positioning accuracy is not required during construction and construction is easy. In addition, in the formation of the longitudinal groove at the time of manufacturing, there is no need for accuracy in the groove width and the groove forming position, and manufacturing is easy.
[0020]
In addition, by making the width of the convex surface in the horizontal direction plural types, the longitudinal grooves can be randomly arranged as a whole. For this reason, in order to give the appearance impression which is a natural stone, the calm design is formed and the board for construction excellent in aesthetics can be obtained .

That is, as shown in FIG. 1, the widths d1 to d5 and the like of the convex surface between the vertical grooves 11 are not all the same but are random.
[0023]
This will be described in detail below.
The building board 1 of this example is a board | plate material which comprises the outer wall of the building 2 as shown in FIG. 7, and consists of an inorganic cement board. The outside of the building 2 is arranged in two rows in the horizontal direction and many in the vertical direction without gaps. A lateral joint groove 19 is formed between the building boards 1 adjacent in the vertical direction.
As shown in FIG. 2, the building board 1 is a horizontally pasting building board that is long in the horizontal direction, and has a width W of about 3 m and a height H of about 45 cm. The thickness is 18 mm.
[0024]
As shown in FIGS. 1 to 5, the upper end 161 has a stepped portion 141 on which a stepped portion 142 of another building plate is placed during construction, and another building plate as shown in FIGS. 4 and 7. An inclined surface 14 is provided which becomes a lateral joint groove 19 formed between adjacent building plates 1 by contact of 1. The lower end 162 is provided with a slope 140 that forms a lateral joint groove 19 between the step 142 and the adjacent building board.

[0026]
Between each longitudinal groove | channel 11, as shown in FIGS. 1-3, the uneven | corrugated pattern 13 which consists of many recessed parts formed in the horizontal direction is provided. In each figure, only a part of the concavo-convex pattern 13 is shown as the concave part, and the others are omitted.
[0027]
The effect of this example will be described.
In the building board 1 of this example, a number of longitudinal grooves 11 are provided in each of an upper stage 151 and a lower stage 152 divided by lateral grooves 12, and these longitudinal grooves 11 are as shown in FIG. , So as not to form a groove penetrating from the upper end 141 to the lower end 142 in a straight line. That is, the vertical grooves 11 are provided so that the positions of the upper stage 151 and the lower stage 152 are different from each other.
As described above, the building board 1 of this example has almost no grooves penetrating in the vertical direction, and thus a large strength reduction in the lateral direction due to the groove formation is suppressed. Therefore, handling during transportation and construction becomes easy.
[0028]
Further, as shown in FIG. 6, when rainwater falls on the building board 1 of this example, the rainwater flows downward along the longitudinal groove 11 of the upper stage 151. After reaching the horizontal groove 12 and being distributed in the horizontal direction as indicated by the arrow 8 shown in the figure, it descends into the vertical groove 11 of the lower stage 152 and further flows downward. Then, in the horizontal joint groove 19 between the building boards 1 shown in FIG. 7, it is similarly distributed in the horizontal direction, and further descends into the vertical groove, and flows down further.
For this reason, even if dust or dirt accumulates in the lateral groove 12 or the lateral joint groove 19, it is washed away when rainwater flows in the lateral direction. Therefore, it is difficult for the appearance to deteriorate due to dirt.
[0029]
Further, in this example, since the longitudinal grooves 11 are formed so as not to penetrate the building board 1 in a straight line, as shown in FIG. 7, when a large number of construction boards 1 are installed adjacent to each other in the longitudinal direction, The deviation of the direction groove 11 is not noticeable.
For this reason, positioning accuracy is not required at the time of construction board 1 construction, and construction is easy. In addition, the formation of the longitudinal groove 11 when manufacturing the building board 1 does not require precision in the groove width and the groove forming position, and is easy to manufacture.
[0030]
Moreover, the building board 1 of this example has a plurality of types of widths of the convex surface defined between the vertical grooves 11 and the horizontal grooves 12, that is, the vertical grooves 11 are randomly formed. Therefore, in order to give the appearance impression that it is a natural stone, a calm design is formed, and an excellent aesthetic appearance can be obtained.
[0031]
According to this example, since there is one horizontal groove 12 and the gap between the vertical grooves 11 is 7 to 10 cm, there are few places where dust and dust accumulate, and rainwater can easily flow and at the same time the vertical grooves 11 Is not penetrating in a straight line, the strength of the building board can be maintained, breakage can be prevented, and the appearance of natural stone can be emphasized from the random feeling. In addition, it is possible to provide a building board that is easy to handle, construct and manufacture and hardly deteriorates in appearance after construction.
