Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a connecting structure of roof plates in a valley portion of a horizontal roof.

[Prior Art] Conventionally, the roof boards from both directions are butted together,
At the bottom, either a method of passing a trough or a specially shaped roofing board made for the valley as shown in No. 60-33228 of the actual construction is connected.

[Problems to be solved by the invention] The conventional method of passing a trough guides rainwater into the trough,
And since it is used as a waterway, when there is a lot of rain or when there are tree branches, leaves, or garbage in this trough,
Water may overflow from the trough and inundate. In addition, it takes time and effort to fit the troughs to the butt positions of the roof plates.

The method using a specially shaped roof requires adjustment of such a specially shaped roof and a differently shaped roof according to the slope of the valley portion, which is a laborious process.

[Means for Solving Problems] Therefore, the present invention is suitable for any slope roof, and can be easily installed by simply inserting the side edge of the roof plate, and can completely shut out rainwater intrusion. Is provided.

Therefore, one side is flatly S-shaped and the other side is flat S-shaped, and the lower ends of the S-shaped and inverted S-shaped portions are curled upward and inward, and the tips are S-shaped. And the inverted S-shaped portions are in contact with each other at a substantially central position, and the curled portions are connected by a C-shaped cross-section plate whose both sides are curved so as to hold the curled portions,
Further, the S-shaped and inverted S-shaped portions are continuously connected to each other at their upper ends to form a valley cover, and the roof plate side ends from both directions in the roof valley portion are inserted into and engaged with the curl tip abutting portion. It is designed to be connected, and under the valley cover, the roof trough where the drain gutters, which are raised at both ends on the back side of the roof plate in both directions, are in contact, are arranged. It is intended to provide a connection structure of parts.

By configuring in this way, by connecting the roof plates to each other without actively guiding the rainwater unlike the conventional trough,
The valley cover prevents rainwater from entering, and even if it does, the valley gutter below will completely refuse the entry of rainwater.

[Embodiment] An embodiment of the present invention will be described with reference to the drawings.

The valley cover A of the present invention is symmetrically bent into a flat S-shape on the left side and a flat reverse S-shape on the right side. The upper ends 1 are connected to each other, and the lower ends are respectively connected. It is curled inward to form curls 2 and 3 and its tip 2
a and 3a are the central positions 4, 5 of the S-shaped or inverted S-shaped part.
Is in contact with. The curled portions 2 and 3 are connected by a scraping plate 8 having a C-shaped cross-section with curved portions 6 and 7 on both sides so as to hold the curled portion.

Then, as shown in FIG. 2, the valley cover A has side edges B1 of the roof plate B in both directions, and the curl portion tip 2a of the valley cover,
3a and the centers 4 and 5 of the S-shaped or inverted S-shaped portions are inserted and engaged and connected. Below the valley cover A, a trough C is arranged so that the draining portion 9 (only one side is shown in the figure) of which both ends are raised contacts the back surface B2 of the roof plate B.

The trough cover has a length corresponding to the step width of the roof plate, and similarly to the roof plate, bent portions in opposite directions are provided in the upper and lower portions so as to be sequentially locked and connected.

[Effect of the Invention] Since the present invention is configured as described above, there is no possibility of rainwater inundation, as compared with the conventional one having only a trough.
Not only will the branches and leaves of the trees not get clogged up, but also the recesses between the roof plates will be covered, and the roof plates will be continuous, giving it a beautiful appearance. It can also be used for roofs of any slope.

Claims (1)

[Scope of utility model registration request] 1. A cross-sectional shape is symmetrically bent into an S-shape with one side flat and an inverted S-shape with the other side flat, and the lower ends of the S-shape and inverted S-shape are curled upward inward. , The tip of which is in contact with the center of the S-shape and the reverse S-shape, and between the curls, both sides of the curl are curved so that both sides are curved. The ends of the roof plate from both directions in the valley part of the roof are inserted into the curl part tip abutting part, and the valley cover is formed by connecting the upper ends of the S-shaped part and the inverted S-shaped part to each other. It is designed to be engaged and connected, and under the valley cover, a drainage part with both ends raised on the back surface of the roof plate in both directions is arranged on the back of a roof gutter that is formed so as to abut. Valley connection structure.
