Then, the joint portion between the upper roof plate 5.5a of the lower roof plate A and the upper roof plate B is covered with a cap 20.

〔Effect of the invention〕

In the present invention, an inclined part 2.2 is formed on both sides of the bottom part 1, and a top part 3.3 is formed outward from the upper end of the inclined parts 2, 2. A groove part 6 and an upward step part 7 are formed on the water side of the lower roof plate, which has a lower roof plate 4 formed above the outer end of the top part 3 and an upper part 5 formed above the outer end of the top part 3 on the other side. A first step 10. a lower roof plate A with a second step portion 11 formed thereon;
The lower water side of the upper shingle B is superimposed on the upper water side of the upper shingle B, and the first step 10. Second step part 11 and lower roof plate A
A first gap 19 and a second gap 19 are formed with the water side surface of the roof and the upward step 7, respectively, and a roof joint structure is formed in which a cap 20 is covered at the joint between the upper parts 5 and 5a. As a result, firstly, the joint between the lower roof plate A and the upper roof plate B can be well protected from rain, secondly, the joint can be made with excellent watertightness at the edge, and thirdly, The joint portion can be made extremely strong, and fourthly, the overall construction of the joint portion can be made relatively easily even if it has a ridge portion, and various other effects can be achieved.

To explain these effects in detail, first, the upper roof board B is provided with the first step part 10 and the second step part 11, and the lower roof board A is provided with the upward step part 7. At the joint part where the upper roof plate B is superimposed on the lower roof plate A, the first
A first gap 18 and a second gap 19 are formed by the step 10, the second step 11, the water-side surface of the lower roof plate A, and the upward step 7 (Figs. 1 to 4). reference).

These two voids can double prevent capillarity caused by the surface tension of rainwater.

In other words, in the case of a large amount of rain or strong winds and rain, for example,
Even if rainwater infiltrates into the first cavity 18, the rainwater can be reliably prevented from penetrating into the next second cavity 19, providing a great effect.

In addition, since the cap 20 covers the joints between the upper ridges 5 and 5a, there is an advantage that the ridges, which are difficult to protect from rain, can be made watertight.

Next, on the water side of the lower roof board A, a groove part 6 and an upward step part 7 are bent, and on the water side of the upper roof board B, a first step part 10 and a second step part 11 are formed. As a result, the cross-sectional properties of the upper roof plate A on the water side and the upper roof plate B on the water lower side are greatly improved.

Therefore, in the joint part, the cross-sectional performance is further improved synergistically at the overlapping location of the lower roof plate A and the upper roof plate B, making it extremely strong.

In addition, if the fitting part 21C of the JITINT side door 21 is fitted into the upper part 5.5a of the joint part, even the M-hoof-shaped roof joint part can achieve more reliable watertightness.

Furthermore, a groove 6 is provided in the lower roof plate A, and if the groove 6 is filled with a sealant 17 and the upper roof rib B is superimposed on the lower roof plate A during roof construction, extremely watertightness can be achieved. Excellent joints can be easily formed. Furthermore, since a portion of the seesaw material 17 is supported by the groove portion 6, the position of the sealing material 17 can be prevented from shifting during roof construction, and reliable construction can be achieved.
