Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a roof made of thin metal sheets.

[Conventional technology]

Recently, with the development of surface treatment technology for materials such as steel, aluminum, and stainless steel, the materials used for metal roofs have become more diverse and sophisticated, and it has become possible to freely select materials according to the building. .

On the other hand, the thickness of roofing materials used to be relatively thick, mainly around 0.3 to 1.0m/m, for conventional color steel sheets, but recently, the materials used have become more sophisticated, and metal sheets with the thinnest thickness possible have been used. The number of roofs that are thatched with wood is increasing.

By the way, as is well known, there are various shapes of such metal roofs, as shown in FIGS. 5 to 8.

Figure 5 shows the case of roofing with tile sticks. In the figure, 1 shows the roof board on the main building 2, 3 shows the underlayment such as asphalt roofing or waterproof paper, and 4 shows the groove board.

Figure 6 shows the case of vertical thatching, Figure 7 shows the case of dovetail roofing, 5 is the standing seam, 6 is the rafter, 7 is the dovetail roof, and 8 is the dovetail fixing nail. Further, FIG. 8 shows the case of the welding method, in which numeral 9 is an angle member fixed on the shedding board 1, and the rising ends of the groove plate 4 are welded and fixed to both sides of the rising piece of the angle member 9.

[Problem that the invention attempts to solve]

In a roof made of such thin metal plates, especially when the groove plate 4 is made of a metal plate thinner than 0.5 m/m, local distortions 10 commonly known as pocket waves occur, resulting in a very unsightly appearance. becomes.

The reason for this is that the roofing material made of the first groove plate 4 is usually formed by roll forming, and the pocket waves are generated during this roll forming. The reason for this is that distortions in the original plate itself, distortions in the molding machine, etc. are accumulated.

Second, even during the on-site construction stage, in addition to the pocket waves that have already occurred in the molded material, distortions due to shims and welding during installation may be added.

Traditionally, in the case of roofs that use colored iron plates, no special measures have been taken to prevent such pocket waves, and other materials have been used to prevent grooves from having fine ribbed waves, commonly known as sazawa waves, or relatively rough pitches. Rib waves are sometimes provided, but this is not very effective in preventing the occurrence of pocket waves, and often only makes it difficult to discern the presence of distortion from the outside.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
To provide a metal thin plate roof that can easily and reliably prevent the occurrence of local distortion and avoid deteriorating the commercial value of a roof made of high-grade materials.

[Means for solving problems]

In order to achieve the above object, when a roof is covered with a combination of metal groove plates, a sheet-like material is provided between the sheathing plate and the groove plate so that the groove plate is curved with its center raised. The gist of this is to intervene.

[Effect]

According to the present invention, the grooved plate is curved so that the central portion is high and the left and right ends are lowered due to the presence of the sheet-like material, thereby applying tension to the grooved plate. As a result, there is no local slack and no local distortion due to pocket waves.

〔Example〕

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

Fig. 1 is a longitudinal sectional front view of the main part showing an embodiment of the metal thin plate roof of the present invention, and Fig. 2 is a longitudinal sectional side view of the entire building, showing the case where vertical seams 5 are formed with vertical flat roofing. . In Fig. 2, 12 is a beam, 13 is a gutter, 14 is a gutter holder, 15 is a ceiling, and 16 is a hanger.

Field board 1 made of century board on main building 2
After that, an underlayment 3 such as asphalt roofing or a base material is applied thereto, and then a sheet-like material 11 is fixed thereon with an adhesive. The mounting location of this sheet-like material 11 is specified by measurement in advance, and the width is such that it contacts only the center portion of the groove plate 4.

As for the material of the sheet-like material 11, if it is made of an elastic material, it should have a rectangular cross section, and if it is made of a hard and inelastic material, it should have a curved cross-section with a chevron-shaped cross section. Preferably wood.

Examples include sheets made of closed-cell foam made of radiation-crosslinked polyethylene, sheets made of glass fibers formed into a felt shape using a needle punch machine, foam sheets made of gypsum dihydrate as its main component and polyester fibers on the surface, asbestos, carbon dioxide, etc. A foamed sheet containing calcium as a main component and soft vinyl chloride as a binder can be used as the sheet-like material 11.

In this way, as shown in FIG.
When a thin groove plate 4 of about 0.5 m/m is placed on top of the groove plate 4 and the left and right ends of the groove plate 4 protruding from the sheet-like material 11 are pushed down, the entire groove curves as shown in FIG.

This curvature is such that the central portion of the groove plate 4 is raised due to the interposition of the sheet-like material 11, and tension is applied accordingly.

Note that the sheet-like material 11 has a thickness of 4 to 10 m/
The width is smaller than the width of the groove plate 4, which is 50 to 150 m/m, and is laid within the range where the groove plate 4 will not be distorted because workers step on the roofing material during roofing construction. It is.

In addition, although the above-mentioned embodiments show examples of vertical roof roofs, the same applies to roofs of other structures such as roofs made of tiled roofs or roofs constructed using welding methods.

[Effect of idea]

As mentioned above, the thin metal sheet roof of the present invention is
When roofing is made of a combination of thin metal plates,
By simply adding a simple configuration, it is possible to reliably prevent the occurrence of local distortion in the groove plate. the result,
Even when using high-quality materials such as aluminum, stainless steel, and titanium, it does not lose its appearance.
The commercial value of the roof can be maintained at a high level.

Further, there is no need to remove distortion from the original plate for molding, and the molding machine may be one that can maintain the dimensional accuracy of the molded material. Furthermore, no skill level is required for roofing work, and the insulation performance of the roof can be improved by laying the sheet-like material to prevent distortion.
