Description

[Detailed Description of the Invention] The present invention relates to an improvement of a roof in which the rising portions of opposing side edges of adjacent metal roof plates such as elongated materials are welded together and sealed.

Conventionally, for the above-mentioned roof, an angle-shaped mounting member 2 is fixed on the main building 1, and the upper end portions of opposing side edge rising portions 4 of the roof plate 3 adjacent to both upper ends of the mounting member 2 are temporarily attached. Weld the entire length of the upper end of the side edge rising portion 4, including these temporary welded portions, to seal the cover 2.
0 is known.

In addition, as shown in FIGS. 2 and 3, a mounting member 6 is connected to the holding member 5 fixed on the main building 1 by means such as tightening, and the side edge of the roof board 3 is connected to the mounting member 6. It is also known that the upper end of the portion 4 is temporarily welded and then welded and sealed.

However, the conventional roof as described above had the following drawbacks. That is, it is necessary to temporarily weld 30 the rising portions of the side edges of the roof plate to the mounting member, and at this time, it is necessary for multiple workers to press the rising portions and bring them into close contact with the mounting member. There is a risk that the roof shingles may be torn off by the wind before welding. Further, even after temporary welding, rain still enters the building because there are gaps between the rising parts other than the parts that sandwich the mounting member. Furthermore, actual welding is performed after temporary welding, but since it is duffle welding and there is a gap as mentioned above, waves are formed in the welded area and the finish is poor, and it is not possible to correct the misalignment of the roof plate after temporary welding. . In addition to the above, when it rains, there is a risk of electric shock, which forces the work to be postponed, which is a major cause of delays in the construction period.

The present invention eliminates the drawbacks of conventional roofs as described above, and makes it possible to construct a roof with good workability.
The aim is to provide a roof that has a good finish after welding and also has less leakage even before welding.

That is, the present invention is a roof in which the opposing rising edges of adjacent metal roof plates are welded together and sealed, and the legs of the holding member are fixed on a roof supporting member such as a main building, and the holding member is The protrusions protruding outward on both sides of the standing portions rising from the legs of the member engage and resiliently hold the engaging portions provided on the rising portions of the side edges of the adjacent roof sheets, so that the holding members of the rising portions It is characterized in that the upwardly projecting upper end portions are crimped together and the crimped portions are welded and sealed.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 4 shows an embodiment of the present invention. In FIG. 4, reference numeral 11 indicates a purlin that is a roof supporting member, and the purlin 11 is made of C-beam steel. Holding members 12 made of extruded shapes of metal such as aluminum are fixed on the main building 11 at predetermined intervals. The holding member 12 has leg portions 12 perpendicular to both sides of the upright portion 12a.
These leg portions 12b are fixed to the main house 11 with screws, and protrusions 12c are provided diagonally downwardly and outwardly from the upper ends of both sides of the upright portion 12a. cut into short lengths.

Side edge rising portions 14 are formed on adjacent roof panels 13, and these rising portions 14 include a downward slope portion 14a that projects obliquely upward toward the holding member 12, and a downwardly sloped portion 14a that continuously extends above the downward slope portion 14a. The engaging portion 14b that bulges toward the holding member 12 side and the engaging portion 14
The upper inclined portion 14c extends obliquely upward toward the holding member 12 from the upper inclined portion 14c, and the upper end portion 14d extends upward continuously from the upper inclined portion 14c.

The roof plate 13 is laid on the main building 11, and the engaging portion 14b of the rising portion 14 is attached to the holding member 12 from above.
At the same time, the upper end portions 14d of the opposing rising portions 14 of the adjacent roof sheets 13 are respectively projected upwardly from the holding member 12, and these upper end portions 14d are connected to the rising portions 14.
Crimp with elastic force. Then, in this state, the crimped upper end portion 14d is permanently welded and sealed without being temporarily welded. Thereafter, if necessary, a metal plate cover 19 with bent engagement parts formed at required locations is placed over the upper end of the rising part of the two welded roof plates as shown on the left side of FIG. It may be fixed by appropriate means.

The roof of the embodiment configured as described above has the engaging portion 14b of the rising portion 14 of the adjacent roof plate 13.
By engaging the protrusions 12c of the holding member 12, the upper ends 14d of the rising portions 14 are crimped together above the holding member 12. The upper end portion 14d can be welded and sealed by the operator, resulting in good workability.

Further, while the rising portion 14 is engaged with the holding member 12, it is possible to correct the relative position of the adjacent roof sheets 13, and since no temporary welding is performed as described above, no waves are formed in the welded portion. , good finish.

Furthermore, since the rising portions 14 of the roof plate 13 are engaged with the holding member 12, the roof panels 13 are hardly blown away by the wind even before welding, and the upper ends 14a of the rising portions 14 are crimped together without any gaps before welding. As a result, there is little chance of rain leaking even before welding.
Furthermore, since roofing work can be carried out even during rainy weather, delays in the construction period are minimized.

In addition, in the present invention, the holding member 12 is the fifth
As shown in the figure, a long hole 1 is provided only on one side of the upright portion 12a.
2d, or as shown in FIG. 6, upper and lower protrusions 12e and 12f are provided at right angles on both sides of the standing portion 12a, and these
Upper and lower engaging portions 14e, 1 provided on the rising portion 14
4f can be changed as appropriate, such as engaging and holding each.
Further, the holding member may also serve as a long rafter perpendicular to the main building. Furthermore, in this invention,
A roof plate may be laid on the main roof through an appropriate member, or a holding member may be fixed.The roof plate may be made of any suitable material as long as it is a metal plate that can be welded, such as a steel plate or a stainless steel plate. Can be used.

The present invention can be applied to both vertical and horizontal roofs.

As explained above, the roof according to the present invention has protrusions protruding outward on both sides of the upright part of the holding member whose legs are fixed on the roof supporting member such as a main house, and the side edge upright part of the adjacent roof plate. Since the provided engaging portion is engaged and held, the upper end of the rising portion is crimped above the holding member, and the crimped portion is welded, temporary welding as in the conventional method is not required, and the crimped portion can be welded. By sealing the roof sheet, it is possible to provide a good finish without waves with good workability, and even before welding, the engagement between the holding member and the rising part prevents the roof sheet from being blown away by the wind. Since the upper end of the rising part is crimped, it has the effect of reducing rain leakage, and since temporary welding work is not required, construction can be performed during rainy days. Since the parts are crimped and welded to each other above the holding member, the holding member is not distorted or damaged by the heat during welding, and therefore the roof plate can be attached to the protrusion of the holding member. It has many excellent features, such as being able to secure the engagement of the engaging portion of the roof plate, and securely fixing the roof plate to the main building etc. via the holding member.
