Description

[Detailed description of the invention] The present invention has a stripe board main body 2 having a plurality of grooves 1 parallel to the longitudinal direction on its upper surface, and the end surface located above the bottom surface 4 of the grooves 1 in the short direction is a vertical plane. 5, the end surface in the short direction of the stripe plate body 2 located below the bottom surface 4 of the groove 1 is a tapered surface 6 having an appropriate cutting angle with the vertical surface 5 in the inner direction of the stripe plate body 2, This relates to a stripe board in which the stripe board bodies 7 are arranged in a row so that the vertical surface 5 of the stripe board main body 2 and the vertical surface 5' of the end face in the transverse direction of the adjacent stripe board main body 7 are in contact with each other. It is.

Conventionally, when a plurality of striped boards made of non-combustible material having grooves parallel to the longitudinal direction are stretched on a ceiling, the end face of the striped board in the transverse direction and the end face of another striped board in the transverse direction are connected to each other. are joined so that the striped patterns parallel to each other are continuous in the longitudinal direction, and after finishing, the ceiling is constructed as if it were formed of a single striped board. In this case, if the end surface of the joint of the stripe board is cut perpendicular to the top surface of the stripe board, when foreign matter gets into the joint of the stripe boards, the joint will be cut due to this foreign material and the single-plate ceiling will be damaged. I can't see it. Therefore, the end faces of the joints of the striped plates were cut at an angle. FIG. 1a shows the above conventional example. That is, the entire end surface in the short direction of a striped plate main body 2' having a striped pattern by forming concave grooves 1 parallel to the longitudinal direction is formed into a tapered surface 6' having an inward cutting angle, and the tapered surface 6' and A tapered surface 6'' of another striped plate main body 2'' formed in the same manner is brought into contact with the striped pattern so that the respective striped patterns become parallel to form a single plate-like ceiling. Fig. 1b is an enlarged side view of the joint between the stripe plate bodies 2' and 2'' shown by A in Fig. 1a, and in the conventional stripe plate bodies 2' and 2'', the cutting angle with respect to the perpendicular line is 15 minutes. It shows that it is ~2 degrees. However, even in this conventional example, a joint break as shown by S in Fig. 1a occurs on a part of the joint surface of the stripe board bodies 2' and 2'', and after the ceiling is finished, the single-plate ceiling It had the disadvantage of not being visible.

In view of the above-mentioned points, the present invention has been developed so that even if striped boards made of non-combustible materials are stretched on the ceiling as a ceiling material, there will be no seam breakage at the joints of each striped board, and after finishing, the striped boards will remain in the form of a single board. The purpose is to provide a striped board that looks like a ceiling and has a beautiful finish.

The present invention will be explained in detail with reference to the drawings. FIG. 2 shows a perspective view of the striped plate of the present invention. That is, in the figure, 2 is a ceiling stripe board main body formed in a rectangular shape from a non-combustible material, and the stripe board main body 2 has a plurality of grooves 1 parallel to the longitudinal direction on its upper surface. Both end surfaces of the stripe board main body 2 in the short direction are as follows:
It is formed of a vertical surface 5 and a tapered surface 6 as shown below. The vertical surface 5 is a cross section perpendicular to the longitudinal direction of the first stripe plate main body 2, and the vertical surface 5
is a part of the end surface above the bottom surface 4 of the groove 1. Further, the tapered surface 6 has a cross section that has an appropriate cutting angle with the vertical surface 5 in the inner direction of the striped plate main body 2, and extends downward from the vertical surface 5, that is, below the bottom surface 4 of the groove 1. It is part of a certain end face. 7 in the figure has the same shape as the stripe plate main body 2,
They are adjacent stripe plate bodies made of the same material and have concave grooves 1' formed on their upper surfaces, and both end surfaces of the adjacent stripe plate bodies 7 also have vertical cross sections perpendicular to the longitudinal direction, similar to the end surfaces. It is formed of a surface 5' and a tapered surface 8 adjacent to the vertical surface 5' and having an appropriate cutting angle inward of the stripe plate body 7. Thus, one end surface of the stripe board main body 2 and the adjacent end surface of the adjacent stripe board main body 7 are brought into contact and joined so that the respective grooves 1 and 1' draw a continuous stripe pattern. . moreover,
An end surface of a similarly formed stripe plate body (not shown) is joined to the other end face in the transverse direction of the adjacent stripe plate body 7, and inner surfaces 13, 13' of the stripe plate body 2 in the longitudinal direction are joined. Stripe board bodies (not shown) formed in the same manner are joined to each other so that the respective grooves are parallel to each other, so that the ceiling as a whole has a monolithic striped pattern. Figure 3a shows the joint surface in the transverse direction between the stripe plate main body 2 and the adjacent stripe plate main body 7, and shows the concave grooves 1, 1'.
At the same time as drawing a continuous striped pattern,
Since the portions above the bottom surface 4 of the groove 1 each have a vertical cross section, the joint break is not visible from the direction C in the figure (the direction C is the ceiling surface). FIG. 3b shows an enlarged sectional view of the joint B in FIG. 3a. That is,
Above the bottom surface 4 of the concave groove 1, the respective vertical surfaces 5 and 5' are in contact with each other, and below the bottom surface 4, the respective tapered surfaces 6 and 8 are cut at a cutting angle of 15 minutes to 2 degrees with respect to the perpendicular line. , and are in contact with each other.

Thus, in the present invention, the end face located above the bottom surface of the grooves in the short direction of the stripe plate main body having a plurality of grooves parallel to the longitudinal direction on the upper surface is a vertical plane, and the grooves are The end surface in the short direction of the stripe board body located below the bottom surface of the stripe board body is a tapered surface having an appropriate cutting angle with the vertical surface in the inner direction of the stripe board body, and is arranged adjacent to the vertical surface of the stripe board body. Since the stripe boards are connected together and stretched on the ceiling with the vertical surfaces of the ends of the stripe board in contact with each other, the joints in the width direction are not noticeable and the ceiling looks like a single board. It has the effect of making it look beautiful.
