Description

[Detailed description of the invention] [Industrial application field] This invention relates to the eaves of so-called shingled roofs covered with sheet-shaped roofing materials. Concerning the eaves of a shingled roof in which a long roof board is used with a mating joint formed and an external mating joint formed on the other side, and these joints connect the roof boards vertically on the rafters. .

[Conventional technology]

So-called shingle roofs are made by bending colored steel plates, aluminum plates, etc. and placing them over open fields. In particular, when roofing a shingle roof horizontally, a horizontally long roof board called a horizontal roof board is used, and an outer fitting joint and an inner fitting joint are provided at both ends of the roof plate, which are bent downward and upward, respectively, and these are fitted into each other. I pieced it together while doing so.

Conventionally, in the case of such a shingled roof, an eave structure as shown in FIGS. 4 and 5 was generally adopted. That is, eave arabesques 2 are attached to the tips of rafters 1 arranged at regular intervals along the slope of the roof, and the outer fitting joints 7 of the roof plates 4 are wrapped around the roof plate connecting pieces 3 provided at the tips. Insert and secure. The end surface of the eave arabesque 2 has a substantially T-shape, and the vertical piece 5 in the center closes the end surface of the rafter 1. Further, a rafter connecting piece 6 extending laterally on the opposite side from the roof plate connecting piece 3 is fixed to the rafter 1 with screws, nails, or the like.

[Problem that the invention attempts to solve]

However, since the roof plate 4 is made of a somewhat thin metal plate in order to reduce its weight, when the eaves are exposed to strong winds, the tip edge 7a of the external fitting joint 7 will break out as indicated by the two-dot chain line in FIG. Bend outward as shown.
Furthermore, if the roof board is exposed to strong winds in this state, the leading end of the roof board 4 will turn over, causing the outer fitting joint 7 to come off the eaves arabesque 2.

In order to eliminate such problems, especially when damage from strong winds or the like is expected, measures are taken to fix the distal end edge 7a of the external fitting joint 7 with nails or the like. but,
These methods require a lot of work to construct and are difficult to disassemble when re-roofing.

Furthermore, at the eaves, rainwater tends to blow under the rafters 1 during wind and rain, causing water to flood into the attic.

This idea was made to solve the above-mentioned problems with the eaves of conventional shingled roofs.It is easy to install, has fewer problems such as roof shingles turning up or coming off, and provides an eaves that protects well from rain. The purpose is to

[Means to solve the problem]

That is, in the present invention, in order to achieve the above object, the inner fitting joint 22 is formed by bending one of the opposing long sides upward and inward, and the other side is bent downward and inward. A plate roof in which the upper and lower roof plates 20 roofed on the rafters 30 are sequentially connected by the inner fitting joint 22 and the outer fitting joint 21 using a long roof plate 20 on which an outer fitting joint 21 is formed. In the roof, an eave arabesque 10 is attached to the tip of the rafter 30, and the outer fitting joint 21 of the roof plate 20 closest to the eave side is attached to the roof plate connecting piece 11 provided at the tip edge of the eave arabesque 10. The jaw-shaped joint support piece 12 extends from the lower rear of the roof plate connecting piece 11 of the eaves arabesque 10 toward the lower front.
is extended, and the outer fitting joint 2 is attached to the joint support piece 12.
A rafter fitting part 13 having a U-shaped side surface is formed on the back side of the eaves arabesque 10 and engages and supports the tip end edge 21a of the eave arabesque 10.
Fit the tip of the rafter 30 into the rafter fitting part 13.
To provide an eave of a board roof characterized by an apron-like waterproof piece 14 extending downward from the lower part of the roof.

[Effect]

In the eaves according to this invention, the leading edge 21a of the outer fitting joint 21 of the roof board 20 is fitted between the roof board connecting piece 11 of the eaves arabesque 10 and the joint support piece 12 below it, so that the leading edge 21a It is fixed so that it does not move and will not turn over even in strong winds.
Moreover, without using nails or the like, just insert the tip edge 21a between the roof plate connecting piece 11 and the joint support piece 12 at the same time as fitting the outer fitting joint 21 of the roof board 20 into the eaves arabesque 10. That's fine.

Furthermore, since the tip of the rafter 30 is fitted into the U-shaped rafter fitting part 13, the end surface of the rafter 30 is completely covered by the rafter fitting part 13. Moreover, since the apron-shaped waterproof piece 14 extends from the lower part of the rafter fitting part 13, rainwater can be prevented from blowing in from the lower surface of the rafter 30.

Such an eaves can be created by simply attaching the eave arabesque 10 as described above to the tips of the rafters 30.
Since the eaves can be covered with the same roofing board 20 used for the ridge above the eaves without using any special fasteners or special roofing boards 20 just for the eaves, the eaves construction is extremely simple. can be done.

〔Example〕

Next, embodiments of this invention and preferred embodiments thereof will be described with reference to the drawings.

The eave arabesque 10 is a long piece made of aluminum or the like, and usually has the same cross section over its entire length except for both ends. The roof plate connecting piece 11 and the rafter connecting piece 16 are made of a horizontal series of flat plate-like pieces, and a vertical piece 15 extends vertically from between them so as to be orthogonal to each other. The leading edge of the roof plate connecting piece 11 is bent downward at a substantially right angle.

A rafter support piece 17 extends from near the lower edge of the vertical piece 15 in parallel with the rafter connection piece 16, and these rafter connection pieces 16, vertical pieces 15, and rafter support pieces 17
Accordingly, a U-shaped rafter fitting portion 13 is formed. Furthermore, from the tip edge of the rafter support piece 17,
A waterproof piece 14 extends downward parallel to the vertical piece 15.

From the position near the vertical piece 15 of the roof plate connecting piece 11,
A joint support piece 12 is extended. The same piece 12 is
The end face is L-shaped, and the horizontally extending tip side is connected to the roof plate connecting piece 11 toward the tip side.
It extends parallel to 1.

The roof plate 20 is made by bending a long steel plate, aluminum plate, or the like, and usually has the same cross section over its entire length except for both ends.
An outer fitting joint 21 and an inner fitting joint 2 are provided on opposing edges to connect these to each other on the rafter 30.
2 is formed. The outer fitting joint 21 is formed by bending the edge of the roof plate 20 downward to form a U-shape with the end surface opening inward. Further, the distal end edge 21a of the external fitting joint 21 is bent downward into a U-shape. On the other hand, the inner fitting joint 22 bends the edge of the roof sheet 20 upward,
It is formed into a mountain shape with an upwardly convex end face.

As shown in FIG.
The connection is made by inserting 1a under the inner fitting joint 22.

The rafters 30 are installed in parallel on the roof sheathing board at regular intervals along the slope of the roof. In the case of a board roof, the rafters 30 are made of metal plates bent into a channel shape.

Using these members, first place eaves arabesque 1 at the tips of the rafters 30 so as to block the tips of the rafters 30.
Fit the rafter fitting part 13 of 0, and connect the rafter connecting piece 16.
are fixed to the rafters 30 with nails, screws, etc. Further, the outer fitting joint 21 of the roof plate 20 is fitted so as to cover the roof plate connecting piece 11 protruding from the tip of the eave arabesque 10, and the outer fitting joint 21 of the roof plate 20 is fitted so as to cover it.
Insert the leading edge 21a between the roof plate connecting piece 11 and the joint support piece 12. In this way, the eaves based on this idea are assembled.

[Effect of idea]

As explained above, according to this invention, by simple construction, an eaves can be obtained in which the outer fitting joint 21 of the roof board 20 does not curl up even in strong winds. Furthermore, it is possible to prevent rainwater from blowing in from the tips and bottoms of the rafters 30, and the rain can be effectively shut off.

In particular, without using a special roofing board 20 only for the eaves, the roofing board 20 is exactly the same as the roofing board above the eaves.
Since the eaves can be roofed using 0, there is no need to separately prepare roofing boards exclusively for the eaves, and roofing work can be easily performed using fewer types of roofing boards.
