Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building exterior material, and more particularly to a building roof material.

[0002]

2. Description of the Related Art Conventionally, many face materials, for example, roof plates have been manufactured on the assumption that the roof surface is flat. For example, the conventional technique as shown in FIG.
In the roof plate engaging structure of Japanese Patent Application Laid-Open No. 5034), one longitudinal side edge 21a of a long metal plate 21 is curved upward, and the tip end thereof is bent upward to stand up. 22
An engaging portion is formed by fixing the rubber 23 at the tip position of the metal plate 21, the other side edge 21b of the metal plate 21 is bent downward in an inverted U-shape, and a bent portion 24 is formed in a step shape at the tip thereof. And a locking portion Y formed by bending the tip thereof downward.

Then, the bent portion 2 upward of the tip of the engaging portion.
Depending on the bending position of 2, the bending position 22f of the upper step of the step-like bending part 24 at the tip of the locking portion Y of the next step of roofing is changed to the bending part 2
1a. However, such a conventional technique has a structure in which the engaging portion and the locking portion are simply engaged, that is, the engaging portion is engaged at a fixed angle, and therefore, it is applicable to a building having a curved roof surface. I couldn't. For example, a roof such as a kamaboko-type gymnasium as shown in FIG. 2 requires a specially designed roof plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 3 shows an embodiment of the present invention and shows an exterior material B applied to a roof whose entire roof is curved as shown in FIG. Figure 3
Shows an example in which the exterior material B according to the embodiment of the present invention is applied to a curved roof.

FIG. 1 shows the face material A used in this embodiment.
Will be explained. The face material A is formed of one long metal plate as a whole, for example, an aluminum alloy plate,
It is composed of a substrate portion 1 and engaging portions 4 and 7 at both ends. The one-end engaging portion 4 includes a rising portion 2 formed by rising one end of the substrate portion 1, a bending portion 3 formed above the rising portion 2 and curved in a substantially semicircular shape, and a bending portion. It is formed of a suspender engaging portion 11 for a suspender 10 formed at the upper end of the portion 3. The rising portion 2 does not need to be provided with a portion in a substantially vertical state as shown in the drawing, and the curved portion 3 may be directly provided as the rising portion.

The other end engaging portion 7 is provided at the other end of the base plate portion 1 downward
That is, the bent portion 5 formed by bending to the back side, and the bent portion 5
And a folded-back portion 6 formed in a substantially U-shaped cross section. The folded-back portion 6 does not have to be formed in a substantially U-shaped cross section as shown in the drawing, but may be a simple linear plate body and the standing wall portion 8 may be provided at the end portion.

When the length of the standing wall portion 8 attached to the end of the folded portion 6 is c and the diameter of the bending portion 3 is a, c
<A is satisfied. In particular, by providing the protrusion 8a at the lower end of the standing wall portion 8 formed at the end of the folded-back portion 6, it is easy to adjust the connection angle of the joint portion, and the adjustment range can be widened.

The exterior material B constructed using the face material A will be described. FIG. 4 shows the joint portion C in the exterior material B in a state of being actually connected, and the entire joint portion C is attached via the heat insulating material 12 by the suspenders 10 attached to the building structure D. There is. To attach such an exterior material B, the exterior material B is attached from the lower side of the roof (eave end).

That is, first, the lower face material A'is arranged, the suspension 10 is engaged with the suspension engagement portion 11 and attached to the building structure D, and then the upper face material A "is attached. Although they are attached together, the standing wall portion 8 of the folded-back portion 6 may be inserted into the bending portion 3 for this engagement, and the angle may be appropriately set while rotating.

FIG. 5 shows a joint portion C in a curved roof, and FIG. 6 shows a state in which the roof surface is flat. In any case, in this engagement state, when the diameter of the bending portion is a, the width of the entrance of the bending portion is b, and the length of the standing wall portion in contact with the bending portion is c, <
It is configured so that a <b holds, and the lower side 9 of the curved portion
If it is configured to incline outward, there will be less runoff of rainwater,
Therefore, the rainwater does not enter the joint portion C, and the preferable exterior material B is obtained. In the present embodiment, the suspension 1
0, the heat insulating material 12, etc. were not described in detail,
For these, conventional techniques are appropriately adopted.

Next, the function and effect of the embodiment will be described. Although the face material A and the exterior material B are configured as described above, basically one type of face material A may be used for the construction on the site, and therefore, the construction method is simplified and easy to perform, and after the construction, Even if the roof is curved to some extent, the joint portion C easily follows this and the watertightness is not impaired. Although the example of the roof structure is shown in the above embodiment, the present invention may be applied to the side wall of other buildings.

The face material A is preferably made of an aluminum alloy or a copper alloy as a metal material, but a hard synthetic resin may be used. Further, since the face material A is variously adopted in its length and width, and the angle of the joint portion C is relatively free to be set on site, the face material A having a large width may be adopted, and It may be appropriately designed in consideration of the overall size, design, workability and the like.

The exterior material B after completion has its joint portion C
In this case, since a certain range of rotation is allowed, even if a person is placed on the exterior material B, the exterior material B can be flexibly accommodated and
Is less likely to be damaged.

[0018]

The present invention has the following effects due to the above configuration. 1. According to the invention described in claim 1, the roof to be mounted does not have to be a flat surface, and whether the roof is curved or uneven to some extent, the connecting angle of the face members can be freely set within a certain range. Because it is possible, various roofing is possible. In addition, the structure is simple, and manufacturing, processing, transportation,
Easy on-site construction. In particular, since it has a degree of freedom in the connection angle while keeping it watertight, it has excellent versatility, is easy to construct, and has great durability.

Further, even if the connection angle between the upper and lower face members of the joint portion changes due to an earthquake or the like, the connection angle automatically changes at the joint portion, and sufficient water tightness can be ensured. Further, if a decompression space is formed between the curved portion and the standing wall portion, rainwater is unlikely to enter the joint portion due to a capillary phenomenon.

Furthermore, in addition to the above effects, by providing the projection on the vertical wall subordinates end portion constituting the folded portion, not only easily performed adjustment of the coupling angle of the joint portion, be wider adjustment range it can.

2. According to the invention described in claim 2,
In addition to the effect of the invention described in Item 1 , c <a makes it possible to increase the connection angle of the continuous face materials even if the roof has a large degree of curvature and can be attached.

3. According to the invention described in claim 3,
In addition to the effects of the invention of Item 1 or 2, rainwater sprayed on the joint can be swiftly flown by the outward inclination of the lower side of the curved portion.
