Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat roofing structure formed of an asbestos cement board, a fiber cement board or the like and used for roofing a house.

[0002]

2. Description of the Related Art Conventional flat roofing materials A have various shapes as shown in FIGS. 6 (a), 6 (b) and 6 (c), and are provided with an uneven pattern on the surface.

[0003]

However, since the flat roofing material A is relatively large in size, the roof surface is monotonous when laid on the roof, and there is a problem that the roof surface is not small and feels cheap. . Also, when the size of the flat roof material is reduced, a feeling of small splitting appears, but there is a problem that the construction is complicated.

The present invention has been made in view of the above problems, and an object of the present invention is to change a method of cutting a front edge and a side edge so that a relatively large size is obtained. It is an object of the present invention to provide a roofing structure of a flat roof material capable of showing a change when a roof surface is blown up without lowering workability .

[0005]

In order to achieve the above-mentioned object, the roofing structure of the flat roofing material according to the present invention comprises a flat roofing material main body.
The flat surface 2 and the uneven surface 3 are continuously provided on the front edge 1a of the
And the uneven surface 3 of the front edge 1a is
Formed so as to reach one side edge 1b, the side of the roofing material body 1
An uneven surface 3 or a notch 4 is provided on the edge 1b, and
The uneven surface 3 of the front edge 1a and the unevenness of the side edge 1b of the roofing material body 1.
The surface 3 or the notch 4 was connected in a stepwise manner .

[0006]

According to the above configuration, by changing the way of cutting the front edge 1a, the flat surface 2 and the uneven surface 3 are formed on the front edge 1a, so that the change can appear on the front edge 1a. Thereby, the flat roofing material A can be roofed so as to have a small split feeling without reducing the workability while keeping the size of the flat roofing material A as it is. In addition, the front edge 1a of the roof material body 1 is
Side edge of the roofing material body 1
1b is provided with an uneven surface 3 or a notch 4, and the roof is
Uneven surface 3 of front edge 1a and uneven surface of side edge 1b of root material body 1
Since 3 or notch 4 was connected in a step-like fashion, the sun
The three-dimensional effect appears due to the shadow of light, and it has a more subtle feeling
It can be roofed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A flat roof material body 1 of a flat roof material A is shown in FIG.
In the case of the embodiment, the width is X and the length is Y. X is, for example, 50 to 100 cm;
Y has a relationship of X> Y, and Y = the roofing foot length × 2 + the overlap margin. The thickness t of the roofing material body 1 is 4 to 10 mm.
The roofing material body 1 is formed of a cement board, an asbestos cement board, a fiber reinforced cement board, a calcium silicate board, or the like. The surface of the roofing material main body 1 has been subjected to uneven pattern processing (approximately 0.2 mm to 2 mm) such as a stone-grain tone or a wood-grain tone. The roofing material body 1 is formed by punching out a green sheet formed by a press or the like. At the time of punching, at least the method of punching the front edge 1a is changed. That is, as shown in FIG. 2A, the front edge 1a is cut straight to form a flat surface 2, or as shown in FIG.
Or is formed. In the case of the present embodiment, the uneven surface 3 is formed to have an inclined surface and to be provided with unevenness, and the width W is about ・ · t to 2t. Further, in the case of the present embodiment, the uneven portions 3 are also formed on the exposed portions of the side edges 1b on both sides of the roofing material main body 1. FIG. 3 shows another embodiment, in which cuts 4 having a width U of about 1.5 to 5 mm are provided in the exposed portions of the side edges 1b on both sides. In the case of the embodiment of FIGS.
The notch 4 is provided and the uneven surface 3 is provided. A flat surface 2 provided by a straight cut on the front end edge 1a and an uneven surface 3 provided by a rough cut are formed continuously, and the length thereof is 1 / 5.A to 4 / 5.A.

[0008] The flat roof material A thus constructed is shown in FIG.
As shown in the figure, it is laid in a single-lettered shape. In other words, the lower flat roofing material A is laid so that it is sequentially shifted sideways to the center in the width direction of the lower flat roofing material A so that the side edges of the upper flat roofing material A are aligned. Where C
Is the length of the roof, and D is the overlap margin. With this construction, the appearance is varied and has a feeling of small splitting. At this time, if there is a cut 4 at the side edge, the roof is laid so as to have a more subtle feeling.

[0009]

[Effect of the invention The present invention 葺設structure of flat roofing materials provided flat surface and the uneven surface continuously to a front edge of the flat roof material body as described above Rutotomoni, the uneven surface of the front end edge roof Lumber
Formed so as to reach one side edge of the main body, and
Provide an uneven surface or notch on the edge, and use the roof
The uneven surface of the front edge of the body and the uneven surface or cut of the side edge
Since it is made into a staircase, by using this flat roof material to construct the roof surface, it is possible to break away from the existing flat roofing condition of the flat roofing material, and in a simple roofing It can bring out the appearance. In other words, when flat roofing materials are
The shadow caused by the sunlight is concave on the front edge of the roofing material body.
There is a difference between the convex surface and the uneven surface or
Therefore, the three-dimensional effect is more apparent due to the shade of sunlight, and
The uneven surface of the front edge reaches one side edge of the roofing material body
So that the front and rear edges are uneven and the side edges are uneven.
Or, an uneven pattern that is continuous in a staircase by cutting
Will be but are formed, clothes such that there is one layer of small split feeling
Is what you can do. Also a relatively large flat
Even when it's covered with a flat roof, it's a simple roof
A different step-like uneven pattern and notch pattern
It can be made to appear , and a pattern is formed on the oblique line when it is roofed by the flat surface at the front edge and the uneven surface (because the way of shadow by sunlight is different between the flat surface and the uneven surface) By changing the length of the flat surface and the uneven surface, it is possible to obtain the one in which the above pattern is further changed. without lowering, also while using those same materials as conventional, the front end edge 及
By simply changing the cuts on the side edges , it is possible to change the feeling of small splitting and the overall roofing design.
