Abstract

PROBLEM TO BE SOLVED: To enable only one worker to rapidly and precisely position even a wide and large planer roofing member of which a positioning mark can be easily formed and which is easily visible. SOLUTION: Planar roofing members are arranged in one lateral row, their left and right ends abutting against one another, and the upper parts of the planar roofing members in a lower row are covered with the lower end parts of the planar roofing members in an upper row, being shifted by one half of the widths thereof from the planer roofing members in the lower row and being arranged similar to latter. Each of these planer roofing members 1 is formed at a lateral central position on the outer surface thereof with an aligning mark 2. Further, aligning marks 3, 4 are formed on the same outer surface at the laterally opposite ends, respectively. The distance (a) between the upper aligning mark 3 and the lower end of the outer surface and the distance (a) between the lower aligning mark 4 and the upper end of the outer surface are set to be equal to each other.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat roof material, especially a large flat roof material, and a construction method for positioning and arranging the flat roof material.

[0002]

2. Description of the Related Art A flat roofing material is a thin cement board, and has shallow groove-shaped alignment marks formed by sharpening shallow grooves on the left and right ends of the surface, the upper end on the ridge side and the central part, respectively. . The alignment mark is used for positioning the flat roof material during construction.

When constructing a flat roofing material, the first row of flat roofing material on the eaves side is arranged in a row in the left-right direction on the sloped roof plate, with its left and right ends abutting each other. The lower part of the flat roof material is covered with the lower part of the eaves on the upper part of the ridge side of the flat plate roof material of the first row, and the plate roof material of the first row is shifted by a half width in the left-right direction to form the flat plate of the first row. The roofing materials are arranged in the same manner as the roofing materials, and the flat roofing materials in the third row and thereafter are also arranged in the same manner as the flat roofing materials in the second row.

[0004]

However, when the alignment mark is provided on the surface of the flat roof material, the central portion of the surface is
It is more difficult to position than the edge of the surface, so it is difficult to provide alignment marks. Further, when the shallow groove is cut with a cutter to provide the alignment mark, the groove of the alignment mark is more difficult to cut in the central portion of the surface than in the edge of the surface.

Further, when a flat roofing material is constructed, the alignment mark at the center of the surface is more difficult to find than the alignment mark at the edge of the surface.

Further, when constructing a large flat roof material having a wide width of, for example, about 1 m, if the flat roof material is positioned by using the alignment marks at the left and right ends of one flat roof material, the Since the alignment marks on both ends are separated by the wide width of the flat roof material, the positioning cannot be performed quickly and accurately by one person.

[0007]

[Means for Solving the Problems] Flat roofing materials are arranged in a row in the left-right direction by abutting the left and right ends of the flat roofing materials, and the flat roofing materials in the upper row and the lower parts are the upper portions of the flat roofing materials in the lower row. In the flat roof roofing material, which is covered with and is displaced in the left-right direction by a half width from the flat roof roofing material in the lower row, and is arranged in the same manner as the flat roof roofing material in the lower row, the flat roof material 1 is illustrated in FIG. As described above, the alignment marks 2 are provided at the left and right center positions on the upper end of the surface, and the alignment marks 3 and 3 are respectively provided on the left and right ends of the surface.
The upper and lower alignment marks 3 have the same distance a from the lower end of the surface and the lower alignment mark 4 has a distance a from the upper end of the surface.

In constructing the flat roof material 1, when the flat roof materials in each row are arranged from left to right, the positioning of the first flat roof material 21 in the upper row is illustrated in FIGS. 2 and 3. The lower end of the flat roofing material 21 is aligned with the lower alignment mark 4 of the right end of the flat roofing material 11 of the lower row, and the upper alignment mark 3 of the left end of the flat roofing material 21 of the upper row is lowered. Aligned with the upper edge of the flat roofing material 11 in the row,
The left end of the flat roof material 21 in the upper row is the flat roof material 1 in the lower row.
1 to the alignment mark 2 at the upper end, the second and subsequent flat roof members 22 in the upper row are positioned by aligning the lower ends of the flat roof members 22 in the upper row with the lower one as illustrated in FIGS. 4 and 5. While aligning with the alignment mark 4 on the lower side of the right end of the flat roof material 12 in the row, the alignment mark 3 on the upper left side of the flat roof material 22 in the upper row is aligned with the upper alignment mark 3 on the right end of the flat roof material 21 in the same row. 3, the left end of the flat roof material 22 in the upper row is abutted against the right end of the flat roof material 21 in the same row.

When arranging the flat roofing materials in each row from right to left, it is the same as the above case except that the left end and the right end of the flat plate roofing material are interchanged.

[0010]

In the flat roofing material, the alignment mark is provided not at the center of the surface but at the edge of the surface, so that the alignment mark can be easily provided and easily found.

Further, when the flat roofing material is constructed, the flat roofing material is positioned by using the alignment mark and the end within the left half or the right half of the flat roofing material.
Even when constructing a large flat roof material with a wide width, positioning can be performed quickly and accurately by one person.
