BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting member used for connecting a roofing metal roof plate.

[0002]

2. Description of the Related Art As a conventional connecting member for a roofing board for a thatched roof,
There is one in which a locking portion having a hat-shaped cross section as shown in Japanese Utility Model Publication No. 57-16977 is provided at the center.
This is a form in which each side edge of the roof plate is inserted from the lateral direction.

Further, Japanese Utility Model Publication No. 56-2740 discloses a water blocking plate for connection in which a deep groove is provided in the center and a protruding piece of a roof plate whose side end is bent downward is engaged in the groove.

Furthermore, both sides of one plate are folded back to the upper side and bent into a bag shape so that they meet at the center, and the engaging piece at the folded side end of the roof plate is joined to the center. A connecting member adapted to be inserted and engaged is known as Japanese Utility Model Laid-Open No. 61-185831.

Furthermore, the invention of the applicant of the present application is disclosed in Japanese Utility Model Laid-Open No. 2-47318.

[0006] The roofing board for a horizontal roof is formed with an engaging portion that rises to the upper surface side in the upper portion and an engaging portion that is bent in a U-shaped cross section on the lower surface portion in the lower portion. The upper or lower roof plate is engaged with the engaging portions and the engaging portions, respectively, and the roofs are sequentially turned.

[0007]

The conventional connecting member having a hat-shaped cross-section with a locking portion protruding in the center does not sufficiently lock the roof plate, and the manufacturing of the connecting material fixes the locking portion. Therefore, there are drawbacks such as work such as rivet stop is required, manufacturing time is long, and sufficient consideration is not given to infiltration of rainwater.

The water stop plate described in Japanese Utility Model Publication No. 56-2740 also has a drawback that it easily comes off because the engagement of the roof plate with the water stop plate is shallow and insufficient.

The connection member described in Japanese Utility Model Laid-Open No. 61-185831 has the highest strength because the folded side edge of the roof plate is engaged with one plate of the folded piece on the upper surface side. There was a defect that the required locking portion was weak and was rolled up by a strong wind, and the roof plate was disengaged.

Since the conventional roof plates are continuously connected in the vertical direction only because the engaging portions and the engaging portions are engaged with each other, the connecting portions between the roof plates in the same row in the lateral direction are between the two roof plates. The measures against rainwater that infiltrate into the gap between the above are not sufficient, and even if a cover is provided on this connection part, if it is raining with a strong wind, rainwater may infiltrate the underside of the roof from above this cover piece. Existed. In addition, this cover piece requires extra cost.

Further, in the case of the connecting structure of the type in which the folded piece at the side end of the roof plate is inserted and locked, the folded back side end of the roof plate is bent so that the upper and lower locking parts and engaging parts are Since it is difficult to turn back due to processing, it is performed only on the central flat portion. For this reason, there is a risk that rainwater may enter from the connection parts of the upper and lower engaging parts and the engaging parts that are not folded back.

The invention disclosed in Japanese Utility Model Laid-Open No. 2-47318 is superior to the other known examples in the strength of the engaging portion between the connecting member and the roof plate, but the water repellent at both ends is Is located outside the shallow bag-shaped recess in the center, so at the engaging portion of the upper and lower roof plates, rainwater that has infiltrated in the vicinity of the water return does not flow into the central recess, so that it is similar to other known examples. There is a risk that rainwater that has infiltrated around the return area will infiltrate into the roof, and a wasteboard is required.

[0013]

Therefore, in the connecting material of the present invention, a single plate is folded to form a shallow bag-shaped recess at the central portion with a narrow opening, and a recess in both directions is provided. The shingles were connected by inserting the folded side edges of the shingles. The opening has a double-folded plate, and the side edge of the roof plate is firmly locked to this portion. Therefore, the roof plate can be reliably locked.

Further, by arranging the water return positions at both ends above the central recess, water that reaches the drainer will also flow into the central recess of the connecting material, and the roof It is possible to prevent water from entering inside.

Furthermore, since the vicinity of the lower end of the folded piece is cut out, water reaching the water-returned portion can flow into the central concave portion without being transmitted to the back surface due to the capillary phenomenon between the folded piece and the water-returned portion. Will increase.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment shown in the drawings.

Both sides of one plate are curled inwardly (curling portions 1 and 2), and the folded pieces 3 and 4 after the curling are performed.
Toward the center and slightly slanted upward, and the first turn-back pieces 3 and 4 from both directions meet at the center, and both have a slight distance a and are turned back in the opposite direction this time ( The folded-back portions 5, 6) and their edges rise up inside the curled portions 1, 2 to form water-folded portions 7, 8.

At the lower ends of the folding pieces 3 and 4, the curl portion 1 is formed.
It is slightly cut away, leaving 2. The roof plate B connected by the connecting member A of the present invention has a side end portion c folded back, and the folded back portion is inserted into the central space a and engaged in the recess d.

The upper and lower ends 9 and 10 of the connecting material A are respectively bent in the vertical direction so as to project into the engaging portions or the locking portions of the upper and lower roof plates.

[0020]

As described above, according to the present invention, the folded portions 5 and 6 are doubled at the engaging portion where strength is required as described above.
Folding pieces 3 and 4 which securely lock the roof plate end portion c, the water return portions 7 and 8 are located on the central recessed portion d, and which are overlapped on the back surface are cut out at the lower end. Since the portions are not overlapped with each other, the water reaching the water return portion is not transmitted to the back surface due to the capillary phenomenon and flows into the central concave portion, so that a sufficient waterproof effect is exhibited.

Therefore, it is possible to provide a product with good workability and low cost without the need for other equipment such as a wasteboard.
