Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an exterior panel attached to a pillar, wall, ceiling or the like of a building.

[Conventional technology and its problems]

In recent years, steel frame structures have been widely adopted, and decorations have been performed on columns or walls using exterior panels, and exterior panels made of natural materials such as stones or artificial materials such as tiles and synthetic plates have also been adopted. ing.

However, the exterior panel according to the conventional example has a problem that the weight is heavy and the construction is troublesome.

Furthermore, since its shape is fixed, it is necessary to manufacture a large number of exterior panels according to the purpose of use.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide an exterior panel that can be easily constructed and can be bent according to a building on site.

[Means for solving problems]

The exterior panel according to claim 1, which is in line with the above purpose, has side plates and end plates connected to the side plates formed around a rectangular metal plate,
An exterior panel in which the side plate is bent at a right angle, the end plate is further bent at a right angle in the outward direction to form a box body with an end plate, and the whole is curved in one direction, the curved panel being formed. The side plate and the end plate connected to the side plate are formed with notches communicating with each other at a predetermined pitch, and each notch of the side plate is formed in a trapezoidal shape extending inward.

The exterior panel according to claim 2 is the exterior panel according to claim 1, wherein a lightweight vibration-proof material is arranged inside the box body.

[Action]

In the exterior panel according to claim 1 or 2, the curved side plate and the end plate connected to the curved side plate are formed with notches communicating with each other at a predetermined pitch, and each notch of the side plate is trapezoidal on the back side. Since the side plate bent at a right angle can be smoothly curved without causing wrinkles or deformation.

Particularly, in the exterior panel according to the second aspect, since the lightweight vibration damping material is arranged inside the box body, the sound can be damped even if the box body vibrates.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention.

FIG. 1 is a perspective view illustrating a method of using the exterior panel according to an embodiment of the present invention, FIG. 2 is a sectional view of the exterior panel, and FIG. 3 is a partial plan view of the exterior panel before assembly. , 4th
FIG. 5 is a perspective view showing a method of manufacturing the exterior panel, FIG. 5 is a perspective view of the exterior panel in a standing state, and FIG. 6 is a perspective view showing another method of using the exterior panel.

First, a method of manufacturing the exterior panel 10 according to an embodiment of the present invention will be described with reference to FIG.

First, prepare a decorative iron plate of about 0.6 to 1.5 mm (referred to as an iron plate whose surface is coated) and a stainless steel plate, and see FIG. 4 (A).
Make notches 11 and 12 by pressing on both sides as shown in. As shown in FIG. 3, the notches 11 and 12 have parallel gaps 13 at both ends, and are formed in a trapezoidal shape on the back side. Then, as shown in FIG. 4 (B), the side plates 14a are formed by bending both sides where the cuts 11 and 12 are formed by pressing, and are bent outward when the cuts 11 and 12 of the side plate 14a spread out in a trapezoidal shape. Forming the end plate 14b,
Further, both sides where the notches 11 and 12 are not formed are also bent to have an L-shaped cross section and formed into a box shape. Where notches on both ends
When bent so as to coincide with the bottom portion 14 of 11, 12, the plate end protrudes to the outside, so that the bending line 15 should be located inside the bottom portion 14 by 2 mm to 5 mm (preferably about 3 mm). Bend. In this case, the bottom portion 14 is contracted, so that the position of the folding line 15 is determined in consideration of the entire bending radius.

With this, the flat exterior panel 10 is completed for the time being,
If necessary, the roller 16 is bent as shown in FIG. 4 (C) and pre-bent as shown in FIG. 4 (D) and FIG.

In the state shown in FIG. 4 (C), it is preferable to store the light-weight vibration isolator 17 in a box, which has the advantage that no light metallic noise is produced even when hit from the outside.

The lightweight vibration-proof material 17 is preferably a lightweight material such as styrofoam or sponge, which can be bent and can be obtained at low cost. Furthermore, when fire resistance is also taken into consideration, glass wool, rock wool. It may be a plate-shaped product containing, for example, as a main raw material.

As shown in FIG. 2, it is preferable that the light-weight anti-vibration material 17 is fixed to the inside of the exterior panel 10 with an adhesive or the like, but even if it is simply fitted in the contact state. good.

In addition, screw holes 18 and 19 for attaching the exterior panel 10 to a base material are provided in the peripheral portion of the exterior panel 10.

Therefore, when this exterior panel 10 is used, for example, as shown in FIG. 1, predetermined columns 20 and 21 (note that FIG. 1 is a model, the columns are small, H-shaped steel or the like is used) to attach a semicircular first base material 22.

A notch for engagement is formed around the first base material 22 so that a second base material 23 having a groove-shaped cross section can be fitted therein.

The exterior panel having a semicircular cross section around the second base material 23
Although 10 is screwed, in this case, the exterior panel 10 bent and formed in advance may be used, or a flat exterior panel may be used and bent according to the second base material 23.

In addition, the portion where the exterior panel 10 is adjacent to and joined to is the first
In the figure, it is wide for ease of explanation,
Usually, it is within 10 to 15 mm. After mounting the exterior panel 10, a backup material is put in this portion and silicon (or polysulfide caulking material) is filled therein.

FIG. 6 shows an example in which the exterior wall 10 is exteriorly coated by using the exterior panel 10. The exterior panel 10 having a flat shape and the flexion-molded exterior panel 10 are used to form an overall structure. There is. It should be noted that although the internal base material is omitted in the description,
By arranging the second base materials 23 as shown in the drawing at predetermined intervals in the vertical direction and screwing the exterior panel 10 thereon, the construction can be carried out smoothly.

[Effect of device]

As is apparent from the above description, the exterior panel according to claim 1 and 2 is provided with notches communicating at a predetermined pitch in the curved side plate and the end plate connected to the side plate,
Moreover, since the cuts of each of the side plates extend in the trapezoidal shape on the inner side, the whole can be bent smoothly.

Then, by the trapezoidal notch formed in the side plate, even when the side plate and the end plate communicating with the side plate are curved so as to be inward, wrinkles are generated in the bent side plate, or deformation is generated. It rarely occurs.

In particular, in the exterior panel according to claim 2, since the lightweight vibration damping material is arranged inside the box body, it softens the metallic vibration to give weight to the sound, and the overall weight is light, so that the smoothness is smooth. Construction can be done.
