That is, the turning material A is composed of a main body A ₁ and a waste plate A ₂ , and its material is a metal plate (color steel plate, aluminum plate, titanium plate, stainless steel plate, copper plate, sandwich steel plate, clad steel plate, etc.) or synthetic resin. The plate is formed by roll forming, press forming, or the like. For example, as shown in FIGS. 1 and 2, a plurality of roofs are formed for each step in a valley portion of the roof to provide a waterproof material, a covering material, and a decorative material. It works.

To explain further, the turning material A is formed into a fan shape with a generally fan-like shape as a whole.
FIG. 4 is an enlarged end view of a portion indicated by a line, and FIG. 5, FIG. 3 is an enlarged end view of a portion indicated by a roll line in FIG.
As shown in FIG. 6 which is an enlarged end view of the portion shown by the line (a) in FIG. 6, the cross section is formed in a mountain shape from the apex 2 corresponding to the central portion of the decorative surface 1.

The main body A ₁ is shown in FIG. 7 (a) (front view), (b)
As shown in the (rear view), the long tongue side which is the upper part is formed with a locking tongue piece 3 which is formed by being bent in a substantially U shape on the decorative surface 1 side, and the back side is formed on the short edge side which is the lower part. 4 has a stepped decorative surface 5 bent and a buffer projection 7 protruding outward or inward is formed at the center 6 of the stepped decorative surface 5, and the tip of the stepped decorative surface 5 is attached to the decorative surface 1 The engaging tongue piece 8 is bent substantially in parallel with the engaging tongue piece 8 and the notch 9 is formed by partially removing the central portion of the engaging tongue piece 8. Further, a goby-shaped fitting tongue piece 10 which is bent inward is formed on both left and right edges of the decorative surface 1.

As shown in an enlarged view of a part of FIG. 8, the scrapboard A ₂ has a waterproof surface 11 and a locking piece 12 in which one end of the waterproof surface 11 is bent inward in a substantially U-shape. And is formed in a fan shape along the locking tongue piece 3 of the main body A ₁ as shown in FIGS. 3 (a) and 3 (b).

The scraping plate A ₂ is integrated with the locking tongue 3 of the main body A ₁ by locking the locking tongue 3 and functions as a fixing part when the roof base α is constructed and a waterproof part after the construction. It is a thing. For this reason, the turning material A can be reliably fixed to the roof base α, and the waterproofness against wind and rain can be greatly improved.

The vertical cross-sectional shape of the decorative surface 1 is substantially the same as that of the decorative surface 13 of the stepped roof material B as shown in FIG. 9, and the stepped decorative surface 5 also corresponds to the step 14 of the roof material B. This creates an appropriate level difference and improves the design.

The locking tongue 3 locks the locking piece 12 of the waste plate A _{2, and} the engaging tongue 8 is engaged with the locked locking piece 12 to turn the turning material A. By connecting vertically, the flaps of the swivel material A are prevented from fluttering, and the engaging tongues 8 of the upper swivel material A are in close contact with the upper part of the decorative surface 1 of the lower swivel material A,
It improves waterproofness.

As shown in FIG. 5, the cushioning projection 7 has a shape which is a pyramid-shaped projection that is widened toward the tip from the decorative surface 1 in the center 6 of the stepped decorative surface 5, or is a projection (not shown). Even if the two decorative surfaces 1 are changed with the apex 2 as a bending line according to the change in the gradient, the buffer protrusions 7 are deformed by elastic deformation, and the center 6 of the stepped decorative surface 5 is not cracked and waterproof. In addition, the design is improved.

Further, the engaging tongues 8 have their lengths l ₂ and l ₃ corresponding to the slope of the roof. That is, as the angle of the roof slope increases, the lengths l ₂ and l ₃ increase.
Is made longer, and the smaller the gradient angle is, the shorter the lengths l ₂ and l ₃ are. That is, as the gradient angle increases, the angle θ _{1 of the} apex 2 shown in FIG. 6 increases. Along with this, the angle θ ₂ of the bottom point 1a in FIG. 3A becomes smaller, and the bottom point 1a shifts in the eaves direction as a whole. Therefore, if the lengths l ₂ and l ₃ of the engaging tongue 8 are short, the engaging tongue 3 is no longer engaged and locked, and the risk of flapping or falling off increases. Therefore, the engaging tongue piece 8 is previously
The lengths l ₂ and l ₃ are formed to be long, and cut according to the slope of the roof at the factory shipment stage. In this way, since only one type of the thatching material A can cope with changes in the roof slope, it is possible to reduce costs such as manufacturing equipment and costs. The turning material A can easily follow the change in θ ₁ by utilizing the elastic deformation of the material.

The backing material C shown in FIG. 10 is a long rectangular plate material, and the material thereof is a foaming board such as a siding board, a siding insulation board, a rock wool board, a plywood, a styrene board, or urethane. It is formed from a synthetic resin foam such as foam, isocyanurate foam, phenol foam or vinyl chloride foam, or a composite plate made of these. The backing material C has a function as a heat insulating material, a raising material, a soundproof material, a sound insulating material, a humidity control material, and the like.

As described above, according to the valley turning material according to the present invention, the valley turning material is fitted by the upper and lower engaging tongue pieces, the engaging tongue pieces and the right and left fitting tongue pieces. If it is locked, it is firmly fixed and does not flutter and is highly waterproof. Since fixing tools such as nails are not necessary at all for fixing the turning material for troughs, the workability is improved, the fixing tool does not appear in the appearance, and the waterproof property is also improved. As with the roofing material, a moderate step appears when the roof is raised, and the aesthetic appearance is improved without any change in the tone at the valley and no trace marks.
By changing the length of the engaging tongue, it is possible to cope with changes in the roof slope with one type of turning material, so it is possible to reduce costs such as manufacturing equipment and costs, and no large inventory space is required. . Since the strain on the central part caused by the change of the roof slope is absorbed by the buffer protrusions, the change of the roof slope can be dealt with by one turning material for the valley part. Since the buffer protrusion absorbs the strain in the central portion caused by the change in the roof slope, it is possible to greatly improve the waterproofness, airtightness, and designability without forming a break in the appearance. There are characteristics and effects.
