For example, Japanese Utility Model Laid-Open No. 53-11720 or Japanese Patent Laid-Open No.
As can be seen in No. 93813, it is conceivable to join the metal panels to be overlapped with each other in a so-called goby-folding manner. However, when a simple general goby folding joint is applied, the surfaces of the metal panels contact each other in the vicinity of the goby folding joining portion, so that there is a problem that rainwater easily enters from the contact portion due to a capillary phenomenon.

The outer edge of the outer metal panel and the side edges of the other metal panels stacked on the upper surface side are in contact with each other at the central portion in the direction orthogonal to the water gradient direction in the lower metal panel. In the exterior metal panel configured as described above, a rising rib formed by bending the peripheral portion upward at a substantially right angle is exposed at the peripheral edge of the overlapping portion where another metal panel is laminated on the upper surface side, and is exposed even after the roofing. On the peripheral edge of the exposed portion, downward ribs are formed by bending the peripheral edge downward at substantially right angles so as to be at the same height as the rising ribs, and are continuously formed at constant heights. Set the length in the water gradient direction so that it is longer than the length of the exposed part in the water gradient direction. The metal panel is configured such that the panel back surface of the portion corresponding to the rising rib of the side edge portion of the overlapping portion is in contact with the metal panel, and a Z-shaped bent portion is further formed on the boundary line between the overlapping portion and the exposed portion. Is formed so that the lower end of the water gradient of the portion overlaps the upper end of the water gradient of the exposed portion, and at the end of the descending rib on the lower end of the water gradient of the exposed portion, in the Z-shaped bent portion of another metal panel. It is characterized in that an engaging portion for engaging is provided.

ることができる。Further, here, between the metal panels to be overlaid (between the metal panel on the upper surface side and the metal panel on the lower surface side), the rising ribs at the periphery of the overlapping portion of the metal panel on the lower surface side and another metal panel on the upper surface side are arranged. The enclosed space, which is completely surrounded by the falling ribs on the peripheral edge of the exposed part, is formed with a certain and sufficient space, and it is possible to prevent the occurrence of the capillary phenomenon between the vertically overlapping metal panels, and at the same time, the enclosed space. Rainwater can be prevented from entering inside (primary waterproofing), and even if rainwater enters the enclosed space, the leakage of rainwater from the enclosed space to the roof substrate side under the metal panel is prevented. It is possible (draining; secondary waterproofing), and it is possible to reliably prevent the occurrence of rain leaks.

における雨漏りの発生を確実に防止できる。That is, in the metal panel of the present invention, the length of the overlapping portion in the water gradient direction is set to be larger than the length of the exposed portion in the water gradient direction, and the metal panel on the lower surface side in the overlapped and roofed state is set. Panel of a portion corresponding to the rising ribs of the side edges of the overlapping portion of another metal panel on the upper surface side, at the upper ends of the rising ribs of the upper end portion (upper end portion in the vertical direction of the water gradient; the top portion) of the overlapping portion of Since the back surfaces are in contact with each other, the rising ribs of the peripheral edge portion of the lower surface side metal panel and the peripheral edge portions of the upper surface side metal panel are provided between the stacked upper and lower side metal panels. The descending ribs form a space that surrounds the entire circumference without interruption.
Since the rising ribs and the falling ribs have the same height and are continuously formed with a constant height, the upper ends of the rising ribs and the lower ends of the falling ribs are different from each other on the plate surface ( Since the back surface and the front surface are in contact with each other and are in close contact with each other, the space is a closed space with a constant vertical space and a sufficient space. The presence of such a closed space prevents rainwater from entering between the upper and lower metal panels due to the capillary phenomenon. On the other hand, the descending rib itself plays a role (primary waterproofing) of preventing rainwater from entering the sealed space due to wind and rain blowing up from below the water gradient. And even if rainwater invades into the enclosed space due to wind and rain blowing, rainwater will be prevented from leaking to the roof substrate side under the metal panel, as a result of the rising rib becoming a draining wall. , It is possible to reliably prevent the occurrence of rain leaks on the roof.

することができるのである。Here, since the engaging portion to be engaged with the Z-shaped bent portion is provided at the lower end of the lower rib, the engaging portion is engaged with the Z-shaped bent portion at a position apart from the back surface of the exposed portion. Then
Therefore, the back surface of the exposed part does not contact the Z-shaped bent part,
Therefore, it is possible to surely secure the above-mentioned closed spaces at regular intervals.

る。Effects of the Invention As described above, the stacking-type exterior metal panel according to the present invention is a stacking-type exterior metal panel used for a roof or an outer wall of a building. The rising ribs that are bent and the downward ribs that are bent downward on the periphery of the exposed part are continuously formed at the same height so that they are lightweight, hard to break and durable. Since it is rich in workability, the workability is good, and between the metal panels that overlap when the roof is raised, the upper ends of the rising ribs and the lower ends of the falling ribs are in contact with the upper surface or the lower surface (rear surface) of different metal panels. There is a fixed and sufficient space between the metal panels that is completely surrounded by the rising ribs of the lower metal panel and the lower ribs of the upper metal panel. Since the enclosed space is formed, the capillarity does not occur between the upper and lower metal panels, and therefore rain leakage due to intrusion of rainwater due to the capillarity is prevented. In addition, the falling ribs on the periphery of the exposed portion prevent rainwater from entering the sealed space by blowing up rainwater from below (primary waterproofing), and even if rainwater enters the sealed space, it will overlap. The rising rib of the portion serves as a draining wall to prevent rainwater from entering the roof substrate side below the metal panel (secondary waterproofing), so that rain leakage can be reliably prevented. Therefore, according to the metal panel of the present invention, it is possible to reliably and sufficiently prevent the occurrence of rain leakage.
