が待たれていたのが現状であった。However, in the lateral connection structure as described above, the stability of the panel is insufficient, it is difficult to obtain sufficient watertightness under strong wind, and it is difficult to improve the construction efficiency. There was a desire for improvement. In other words, under strong wind, a displacement force or a deformation force in the lifting direction acts on the roof panel. However, as a connection structure of the horizontal connecting portion between the roof panels, the position of the roof panel is opposed to the displacement force or the deformation force. It is required to be able to prevent displacement and deformation, generation of a gap at a lateral joint between roof panels, and the like. Until now,
Various connection structures intended to prevent displacement or deformation of the roof panel have been proposed, however,
There are problems that the effect of preventing the displacement and deformation of the roof panel is insufficient, the structure is complicated and it takes time to construct, and the aesthetic appearance can not be secured by design,
Nothing was right. For example, under adverse conditions, such as when a large typhoon is exposed to intense wind and rain for a long time due to long-term typhoon, very large displacement and deformation forces act on the roof panel due to the occurrence of waving behavior of the entire roof. As a result, the connection between the roof panels is disengaged, and the roof panels are lifted up or turned up.However, there is almost no connection structure that can maintain the connection state between the roof panels against such a strong displacement force or deformation force. . Furthermore, if the connection structure is excellent in workability and design, it can be said that it does not exist at all, and the current situation is that future development has been awaited.

In addition, since the upper surface forming portions 24 of the exterior panels 20 on both sides are closely arranged along the protrusions 12e of the joint component 12, the protrusions are prevented. The displacement in the lateral direction and the change in the direction are also restricted by the contact with the portion 12e, where the change in the direction of the exterior panel 20 means the exterior on the base 13 on which the exterior panel 20 is installed. This is a displacement in the rotation direction of the panel 20, and the change in the direction is such that the water gradient upstream or downstream end of the side surface facing the ridge 12e of the upper surface forming portion 24 abuts on the ridge 12e. Regulated by Is. The superior rigidity of the joint part 12 that is a T-shaped cross section, the outer panel 20

It is surely prevented. Thereby, for example, even under bad conditions such as storms, the lateral connecting portions 1 of the exterior panels 20 on both sides are formed.
1 can be reliably maintained. The vertical joints 27 between the exterior panels 20 have sufficient connection stability due to the engagement between the upstream folded portion 28 and the downstream engagement portion 29 provided over substantially the entire working length direction of the exterior panel 20. And watertightness are ensured. Accordingly, disconnection between the vertical and horizontal exterior panels 20 can be prevented, and watertightness can be maintained, even in a bad environment such as a storm that involves deformation such as waving of the entire roof 10.

作用することを回避できるといった利点がある。Further, in the horizontal connecting portion 11, the ridge 12e is sandwiched between the upper surface forming portions 24 of the outer panels 20 on both sides, so that the pressing force acting on the ridge 12e from one outer panel 20 is formed. Since the other exterior panel 20 supports the pressure, the lateral displacement and the change in the direction of each exterior panel 20 on both sides can be more effectively regulated. However, the upper surface forming portion 24 of each exterior panel 20 does not necessarily have to be in close contact with the ridge portion 12e, and a slight clearance can be secured. In this case, since the lateral displacement and the change in the direction are slightly allowed in each of the exterior panels 20, it is assumed that the external force causing the lateral displacement and the change in the direction directly acts as a deformation of the exterior panel 20. There is an advantage that it can be avoided.

By engaging the upper fixing portion 12d with the downstream engaging portion 29 of the exterior panel 20 on the upstream side of the water gradient, the upper fixing portion 12d is installed at the horizontal connecting portion 11 between the exterior panels 20, so that the construction can be easily performed. . Moreover, this joint part 12 is connected to the horizontal connecting part 11 of the existing exterior panel 20.
Also, it can be constructed by inserting the ridge 12e between the upper surface forming portions 24. There is almost no adverse effect on the appearance.

れる。The present invention is not limited to the configuration described in each of the above embodiments, and it goes without saying that various modifications such as the specific configuration of the exterior panel and the joint parts are possible. As the exterior panel applicable to the present invention,
Various configurations can be adopted, but a configuration in which the ends in the working length direction of the upper surface forming portion can be arranged close to each other at the horizontal connecting portion is employed. However, the working width does not always coincide with the direction of the water gradient of the roof that is roofed by the connection between the exterior panels, and includes a case where the working panel is slightly inclined with respect to the water gradient. Therefore, the “working length” is not limited to the lateral direction substantially orthogonal to the water gradient direction, but includes a direction slightly inclined to this. The ridge of the joint component is inserted between the ends of the working length portion of each exterior panel.
