Let y) = p be the reference pitch.

 First, the field width U is divided by the reference pitch p, and U / p = a ... The remainder ca is the number of columns of the roof plate 5.

When the remainder c is 0 (c = 0), the roof plate 5 and the connecting member A fit in the positional relationship shown in FIG.

The remainder c is smaller than half the reference pitch p (c <p / 2)
When the remainder c is larger than half the reference pitch (c> p / 2), this is called negative adjustment, and a separate adjustment method is adopted for each.

§In the case of positive adjustment U ÷ p = a ...... remainder c (c <p / 2) This remainder c is divided by a, and c ÷ a = α The obtained value α becomes the necessary adjustment amount per row. .
Therefore, if this α is added to the reference pitch p, the desired pitch of the roof plate 5 is obtained.

§ In the case of negative adjustment U ÷ p = a ...... remainder c (c <p / 2) Divide the difference between the standard pitch p and the remainder c by the number of roof plate rows a plus +1 (p−c) ÷ (A + 1) = α The calculated numerical value α is the necessary adjustment amount per row, and if this α is subtracted from the reference pitch p, the desired pitch dimension of the roof plate 5 can be calculated.

FIG. 29 is a standard set drawing, in which case the engagement preventing wall 29 of the roof plate 5 is located at the center of the lower width adjusting portion 16 and therefore no adjustment is required.

FIG. 28 is a diagram of minus adjustment. In this case, the engagement prevention wall 29 of the roof plate 5 approaches the hanging piece 14 and is located inside the lower width adjusting portion 16 to be minus adjusted, which is the minus mounting position. .

FIG. 30 is a diagram of plus adjustment. In this case, the engaging waterproof wall 29 of the roof plate 5 approaches the sliding curved portion 13 and is located outside the lower width adjusting portion 16 for plus adjustment. The position.

Effect of the Invention As described above, since the width adjustment mounting method of the roof plate of the present invention is to connect the roof plate by inserting the side rising wall of the roof plate into the wide lower width adjustment portion of the connection member, Even if the pitch between the connecting members changes according to the change in the field width, or if there is an error in the mounting position of the connecting members, it is possible to adjust the width of the standard width roof plate and mount it accordingly. Abnormality due to thermal expansion and contraction of can be absorbed. Moreover, since the movable amount of the roof plate is large, the dimensional accuracy of the members can be low.

In addition, since the connecting member is provided with a sliding bend, the sliding bend guides the edge of the roof plate below the overhanging part, and after all the connecting members are allocated and fixed as calculated, the connection is made. A roof plate can be laid between the members, so that the installation work can be performed efficiently, and only one member needs to be carried onto the roof at a time, which is safe for roofing work. Sex increases.

Furthermore, since the side rising wall of the roof plate is located inside the sliding curved part, it is difficult for the side rising wall to come off from the lower width adjustment part, and rainwater that has dropped from above does not cross the side rising wall. It is hard to leak water, and rainwater that has fallen along the connecting members is drained toward the eaves using the roof board as a gutter, and does not flood the roof substrate.
