Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a building exterior panel suitable for construction without constructing a scaffold.

[0002]

[Prior Art]

 In recent years, due to the effective use of land, the distance between adjacent buildings is often very small, and it is often difficult to construct scaffolds around buildings for construction. However, the general exterior panels are usually fixed on the foundation material etc. by the work from the outside of the building, assuming that the scaffold is installed, so if there is no scaffold, Has a problem that the work is dangerous and that it takes a long time even if the work can be performed without a scaffold.

In order to solve such a problem, metal fittings for attachment are fixed to the back surface of the exterior panel at appropriate intervals by welding or the like, and by utilizing the metal fittings, the back surface side, that is, the inside of the building is fixed. Although the work may be done, in general, the panel for exterior is thin, and the thin metal plate is preliminarily subjected to surface treatment to improve weather resistance, corrosion resistance, stain resistance, chemical resistance, etc. In many cases, it is very difficult to fix the metal fittings for mounting with the required strength. Moreover, since the metal fittings partially attached at appropriate intervals may come off, there is a problem in reliability.

[0004]

[Problems to be solved by the device]

 The technical problem of the present invention is to fix the exterior panel for construction by the work from the inside of the building, by attaching the engaging part of the mounting bracket having sufficient strength to the back side of the exterior panel by a simple means. To form.

[0005]

[Means for Solving the Problems]

 The exterior panel for a building of the present invention for solving the above problems is formed of a metal thin plate, and is fixed to the building at a folding portion formed by folding an appropriate number of intermediate portions of the thin plate inward. It is characterized in that a locking portion of a mounting metal fitting is formed.

[0006]

[Action]

 The folded part formed by folding the middle part of the thin metal plate to the inner surface side does not come off like a metal fitting fixed by welding, and the reliability of mounting the exterior panel becomes extremely high. Further, the folded-over portion can be easily formed by bending the thin metal plate during forming. Then, by locking the fittings to the locking portions formed on the folded portion, the exterior panel is easily and firmly fixed to the building base material by the work from the inside of the building.

【Example】

 1 and 2 show a state in which a building exterior panel 1 according to the present invention is fixed to a building base material 10. The exterior panel 1 is formed of a thin metal plate having weather resistance, corrosion resistance, stain resistance, chemical resistance, etc., and is attached to the outer wall of the building at a suitable location in the middle part of the thin plate. The folded-over portion 2 is formed by folding the folded-inward portion 2 to the inner surface side, and the folded-over portion 2 is bent in a U-shape to form the locking portion 3 of the mounting bracket 11 for fixing to the building. .. The both end portions 4 and 5 of the exterior panel 1 can be formed in any joint shape generally used for joining with an adjacent panel.

As the fitting 11 for mounting, a bolt 12 provided with a locking hook 13 at its tip, a locking member 14 for locking the base material 10, etc., and a nut 16 screwed into the bolt 12 are provided. The thing provided is illustrated. In this fitting, the locking hook 13 is locked to the locking portion of the exterior panel 1, the locking member 14 is locked to the building base material 10, and the bolt 12 is fixed to the locking member 14. The exterior panel 1 is fixed by inserting it and screwing the nut 16 into the bolt 12. The mounting metal fitting 11 is not limited to the one illustrated in the drawings, and a metal fitting having another suitable structure can be used. Further, the panel 1 can be fixed not only to vertical and horizontal base materials but also to arbitrary members of a building including studs and furring strips.

On the other hand, the locking portion 3 formed on the folded-over portion 2 of the exterior panel 1 is bent into an appropriate shape as shown in FIGS. be able to. In FIG. A, a groove portion 6 is formed on the front surface side of the exterior panel 1 by using the folding overlap portion 2, and the folding overlap portion 2 is bent in a U-shape to form a locking portion 3. In the case of FIG. 6B, the pair of U-shaped locking portions 3 are formed in the folding portion 2, and in the same drawing C, when the hook-shaped locking portion 3 is formed in the folding portion 2. Fig. D shows the case where the folding portion 2 is bent in an L-shape to form the locking portion 3, and Fig. E shows the case where the folding portion 2 is bent in the T-shape to form the locking portion 3. In the same drawing F, the case where the folding portion 2 is not bent, but the folding portion 2 is provided with a hole through which the locking hook 13 of the mounting bracket 11 and the like are formed to form the locking portion 3, respectively. It is illustrated. In the folded portion 2 of the structural examples A to E, holes for locking the fitting 11 can be provided if necessary.

In the engaging portion 3 of the exterior panel 1, it is desirable to provide a contact surface 3a that abuts the base material 10 of the building to which it is attached, in order to increase the joint strength. As shown, the linear portion can be brought into contact with the base material 10, and can be appropriately selected according to the shape of the member to which the exterior panel 1 is to be attached.

The exterior panel having the above structure can be easily formed including the folding portion 2 and the locking portion 3 by folding the middle portion of the thin metal plate to the inner surface side when forming the thin metal plate. You can Further, the folded-over portion 2 is unlikely to come off like a metal member fixed by welding, so that the reliability of attachment of the exterior panel can be remarkably enhanced.

Thus, by locking the mounting member 11 to the locking portion 3 formed in the folded portion 2 on the inner surface side of the exterior panel 1, the exterior panel 1 can be constructed without a scaffold. The work can be easily and firmly fixed to the building base material 10 or the like from the inside of the object, and the work is simple, so that the work can be performed in a short period of time. The exterior panel 1 may be fixed with its longitudinal direction oriented either vertically or horizontally.

[Effect of the device]

 According to the present invention described in detail above, the engaging portion of the mounting bracket for fixing the exterior panel by the work from the inside of the building is provided on the rear surface of the exterior panel by a simple means. Since it can be formed with sufficient strength, it does not come off like metal fittings fixed by welding, the reliability of the mounting of the exterior panel can be remarkably increased, and the fixing work to the building is also possible. Because it is simple, it can be installed in a short period of time.
