BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof connector for fastening a roof panel to a roof panel or a wall panel.

[0002]

2. Description of the Related Art Generally, a roof panel is placed on a roof of a house, and is then tied to a wall panel or a roof panel as a roof receiving member by a roof connector.

FIG. 8 is a view showing a state of attachment of a conventional roof connector for fastening a roof panel to a roof panel.

In FIG. 8, reference numeral 400 denotes a roof connector, which is formed into a substantially rectangular roof panel side fixing piece 410 and a roof panel side fixing piece 410 in an asymmetric shape. A panel-side fixing piece 420 is vertically bent at the right end of the panel-side fixing piece 410.

[0005] The roof connector 400 is attached at a keraba portion vertically joined to the roof cutting panel 200.

That is, the roof panel side fixing piece 410 is screwed and fixed inside the core member 110 of the roof panel 100, and the roof cutting panel side fixing piece 420 becomes the roof cutting panel 200.
The roof panel 100 and the roof panel 200 in the keraba portion are fixed by screws while being in contact with the upper end surface of the
And ties are made.

FIG. 9 is a view showing a conventional roof connector for fastening a roof panel to a wall panel.

The roof connector 500 also has a roof panel side fixing piece 510 and a roof panel side fixing piece 510 and an asymmetric rectangular wall panel side fixing piece 520. The roof panel 100 has a girder portion. Since it is joined to the wall panel 300 while being inclined, the center axis l of the roof panel-side fixing piece 510 is set so as to intersect the wall panel-side fixing piece 520 at an inclination angle of the roof panel 100.

[0009]

However, in the above-described conventional roof connector, the roof connector 400 for the keraba of the roof panel 200 and the roof connector 5 for the girder of the wall panel 300 are provided.
Since two types of roof connectors different from 00 were required, a roof connector 400 or 500 suitable for the installation site had to be found and attached from a large number of building components at the construction site. Is complicated, and there is a problem of delaying on-site work.

[0010] The roof connector is formed by punching a single iron plate to mass-produce iron pieces having the outer shape of the roof connector, drilling a screw hole in each iron piece, and bending each iron piece. It is common to use

However, the conventional roof connector 500 (40
0) is the shape of the roof panel side fixing piece 510 (410) and the wall panel side fixing piece 520 (roof panel side fixing piece 42).
Since the shape of 0) is set asymmetrically,
Poor yield.

That is, as shown in FIG. 10, the roof connectors 500 must be punched apart from each other, so that a wasteful portion cannot be used as a roof connector, as shown by hatching in FIG. There is a disadvantage that the production cost is increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object the purpose of using one kind of roof connector so that the roof panel can be fastened to a roof panel receiving member whose roof panel is orthogonal. It is another object of the present invention to provide a roof connector that can also be used for fastening to a roof receiving member in which a roof panel is inclined and intersects, and that can improve the production yield.

[0014]

In order to achieve the above-mentioned object, the present invention provides a roof receiving member such as a panel or a beam on a building body side, and a core material crossing the roof receiving member. A roof panel that is fastened at the intersection of the roof panel and a longitudinally elongated parallelogram, and has a long side extending from the end of one short side and the other end of one short side. A metal plate body where a line extending more vertically intersects is bent at a right angle at a line position extending vertically from the short side to form a roof panel side fixing piece and a roof receiving member side fixing piece, and the roof Attach the roof panel to the lower edge of the panel side fixing piece.
A concave step for positioning is formed, and a convex step is formed at a position opposite to the concave step of the roof receiving member side fixing piece so as to project in a shape corresponding to the concave step.

[0015]

In the present invention having the above-described structure, the roof panel is fixed to the roof panel as a roof receiving member at the keraba portion where the roof panel is perpendicular to the roof panel. When the side fixing piece is fixed to the roof panel and the roof receiving member side fixing piece is fastened and fixed to the roof cut-off panel, the roof panel is tightened to the roof receiving member.

At this time, since the position can be determined at the concave step portion of the roof panel side fixing piece, the work of attaching the roof connector can be performed efficiently and quickly.

When the roof connector is attached to a girder portion where the roof panels intersect at a fixed inclination angle, the roof panel-side fixing piece is applied to the roof panel, and the roof receiving member-side fixing piece is used as a roof receiving member. When the roof panel-side fixing piece is fixed to the roof panel and the roof receiving member-side fixing piece is fastened and fixed to the wall panel or the like in a state of being in contact with the wall panel or the like, the roof panel is tied to the wall panel or the like.

Therefore, this one roof connector not only allows the roof panel to be fastened to the roof panel receiving member where the roof panel crosses at right angles, but also enables the roof panel to be fastened to the roof receiving member where the roof panel is inclined and intersects. It can be shared.

Further, the roof connector before bending is a substantially parallelogram having a point symmetry, and is recessed at a position opposite to the recessed step by the recessed portion of the roof panel side fixing piece. Since the protruding step of the shape corresponding to the step is protruded, it is possible to punch the roof connectors close to each other in one metal plate, so there is an unnecessary part that can not be used as a roof connector. It hardly occurs, and the production yield is very good.

[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.
