Description

[Detailed description of the invention] The present invention provides an upper flap 2 that protrudes from the ridge side end of the corpse 1 to the surface side of the corpse 1, and also extends the body 1 from the eave side end of the corpse 1.
A lower flap 3 is provided protruding below the eave side of the body, one groove 4 is curved on one side of the corpse 1, and two grooves 5a, 5 are formed on the other side of the corpse 1.
b, and the inner groove 5a of the two grooves 5 is used as a fitting part on the lower surface of the groove 4, and the outer groove 5
A horizontal flap 6 is provided on the surface side of the horizontal piece 13 that extends in the horizontal direction.
The purpose of this is to provide a roofing material which can prevent water leakage at horizontal joints and has fewer steps in the vertical direction when constructed.

As shown in Figure 4, in conventional roofing materials, the protrusions on the side edges are overlapped and joined horizontally, and rainwater infiltrates through capillary action from the area where the protrusions overlap, causing rainwater to flow to the back side of the roofing material. It had the disadvantage of rotating.

The present invention solves the above-mentioned drawbacks and will be explained in detail below with reference to examples.

A corpse 1 made of a metal material has a horizontally elongated substantially rectangular plate shape, and an upper ridge portion 2 having a generally abbreviated cross-section extends from the ridge side end to the surface side of the corpse 1 over the entire length in the lateral direction. A lower flap part 3 having an abbreviated cross-section extends downward from the eave side of the corpse 1 over substantially the entire length in the lateral direction from the end of the eave side of the corpse 1, and the lower flap part 3 is open on the back side of the corpse 1. ing.

On one shaft of the corpse 1, there is a groove 4 having a U-shaped cross section with an open upper surface extending over almost the entire length between the eave side end and the ridge side. The side edges of the groove 4 are flush with each other, and a concave curved portion 11 having the same shape as the groove 4 is provided on the vertical piece of the upper flap 2 on the ridge side of the groove 4 over the entire length in the vertical direction.

In the center of the corpse 1, there are a plurality of grooves 7 spaced apart in parallel over the entire length from the eave side end to the ridge side, and on the other side of the corpse 1, there are grooves 7 spaced apart from each other in parallel over the entire length between the eave side end and the eave side. Two grooves 5a and 5b are provided adjacent to each other over substantially the entire length of the groove.

The groove 5a is designed so that the groove 4 can be inserted into the groove 5a.
A concave groove 5a is formed on the vertical piece of the upper flap 2 on the ridge side of a and 5b over the entire length in the vertical direction.

A concave curved portion 12 having the same shape as the concave groove 5b is provided.
There is a horizontal piece 13 extending horizontally on the outside of the horizontal piece 1.
At the end of the body 3, a horizontal gap 6 having a U-shaped cross section is provided extending over the entire length between the eaves side and the ridge side and has a U-shaped cross section and is open on the side of the groove 5b.

To construct a roof, a roof base material 9 is laid on the field material 8 attached to the rafters, the roof material 10a is fixed to the field material 8 via the roof material 9 with nails, etc., and the other roof material 10b is attached. Concave groove 5a of the roof board material 10a to which the upper spring part 2 is fixed on the groove part 4 side
, by inserting the groove 4 into the inner groove 5 by inserting it into the upper flap 2 on the 5b side.
a, and at the same time, fit the concave curved part 11 into the concave curved part 12a, and fit the horizontal flap part 6 of the roofing material 10a into the groove part 4 of the roofing material 10b.
Roofing materials 10 are horizontally spliced so as to face each other with a gap between the side and back surfaces.

To connect the roofing materials 10 in the vertical direction, the roofing materials 10a on the eaves side fixed to the sheathing material 8 are connected to the upper seams 2 which are open on the front side, and the lower seams 3 where the back side of the roofing materials 10c on the ridge side is open. are inserted and locked to connect the roofing material 10 in the vertical direction.

In this invention, a groove is curved on one side of the corpse, and a groove is provided on the other side of the corpse, so that the groove of another roofing material can be inserted into the groove and the roofing material can be easily horizontally spliced. Of course, one groove is curved on one side of the corpse, two grooves are provided on the other side of the corpse, and the inner groove of the two grooves is connected to the fitting part on the lower surface of the groove. Therefore, by inserting the groove of another roofing material into the inner groove of the two grooves of one roofing material and making a horizontal connection, a space is formed in the outer groove, and capillary action occurs. In addition, a horizontal gap is provided on the surface side of the horizontal piece that extends horizontally from the groove on the outside of the groove provided on the other side of the corpse. Even if rainwater enters through the joints due to capillary action, it can prevent further leakage at the lateral edges on the outside of the groove, and it also prevents water from leaking further from the ridge side edge of the corpse to the surface side of the corpse. At the same time, a lower flap was set up to protrude from the end of the eave side of the corpse, so the lower flap of the roofing material on the ridge side was locked to the upper flap of the roofing material on the eave side, and the roof was fixed. The materials can be joined vertically, and the bottom seam protrudes below the eaves of the structure.
The lower edge is inclined and protrudes downward from the eave side of the roofing material.
The difference in level between the eave side of the roofing material on the ridge side and the ridge side of the eave side roofing material can be reduced, resulting in a good appearance.
