Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a cement-based or other flat sheet roof material having a flat plate shape.

[Background Art] Although a flat-plate roof material A having a flat plate shape is conventionally known,
It is most preferable that the flat plate roof material A has a rectangular shape in terms of trampling. The flat roof material is usually aligned next to the upper corner of the already roofed flat roof material A as shown in FIG. Then, while positioning this portion with the finger 7, the flat plate roofing material to be constructed next is rotated to horizontally arrange the flat plate roofing material A as shown in FIG. 5 (b). Then, it is confirmed whether the lower end corners of the flat roof material A match each other, and then the flat roof material A is fixed with nails.
However, in the above-mentioned conventional example, as shown in FIG. 5 (a), the flat plate roofing material A to be constructed next to the upper edge corner part of the already-roofed rectangular flat plate roofing material A is slanted and the upper end corner portion is positioned. When the flat plate roofing material A to be constructed adjacently is rotated by pressing this part with the finger 7 and centering it here, use the finger to touch the abutting part of the upper end corner of the rectangular flat plate roofing material A. Since it is pressed, the angle of α shown in FIG.
It is easy to slide in the direction of the arrow in the figure. Therefore, when rotating the flat roof material A, it is difficult to hold it in the state of accurate alignment. There was a problem that I had to In addition, when the flat roof material A is constructed, the other upper end corner portion of the flat roof material A is grasped by the other hand, but this portion has a problem that it is difficult to grasp because it is a right angle.

[Object of the Invention] The present invention was devised in view of the above-mentioned conventional problems, and its purpose is to maintain workability while maintaining a rectangular original shape so as to prevent stepping cracks as much as possible. It is to provide a flat roof material that can improve the

DISCLOSURE OF THE INVENTION In the flat roof material of the present invention, only the shoulders on both upper sides of a rectangular flat roof main body 1 are obliquely cut to form an inclined edge portion 2, and a lower end portion of the inclined edge portion 2 is formed. Is a narrow horizontal edge portion 2a, the length of the horizontal edge portion 2a is about 10 mm, and the horizontal edge portion 2 is located above the upper end of the exposed portion 3 of the flat sheet roofing material body 1. By adopting such a configuration, the above-described object of the present invention is achieved. That is, since only the shoulder portion of the rectangular flat roof material 1 is obliquely cut to form the slanted edge portion 2 and the lower end portion of the slanted edge portion 2 is formed as a narrow horizontal edge portion 2a, the flat sheet roofing material body is formed. Sloping edge 2 to align the upper corners of one another
By aligning at the lower end of the and rotating it by pressing it with your finger, you can surely press it with your finger and rotate it. Since the horizontal edges 2a do not align with each other, you can easily find the vertical deviation by checking this, and even in this case you can touch the horizontal edge 2a with your finger and move the flat roof material A up and down. The position can be easily adjusted, especially by setting the length of the horizontal edge 2a to about 10 mm,
The total length of the horizontal edges 2a adjacent to each other when touching with a finger is about 20 mm, which is slightly wider than the width of an adult finger, and alignment work using fingers is possible. It was made easy.

Hereinafter, the present invention will be described in detail with reference to embodiments. Flat roof material 1
Is formed of asbestos board, asbestos cement board, fiber-containing cement board, or other known roof molding material,
It has a rectangular shape. Then, only the shoulders on both sides of the upper portion of the rectangular flat roof main body 1 are obliquely cut to form an inclined edge portion 2. The lower end of this inclined edge 2 is a narrow horizontal edge 2a. This horizontal edge 2a
Is preferably set to a width in the range of approximately half the width of a human finger to the width of several fingers. The horizontal edge portion 2a is located above the upper end of the exposed portion 3 on the lower surface of the flat plate roofing material body 1. Although the flat roof material A is configured as described above, only the shoulder portion of the rectangular flat roof material body 1 is cut, so that the rectangular original shape is left and the lower end of the inclined edge portion 2 is horizontal. Since the edge portion 2a is located above the upper end of the exposed portion 3, the overlapping area at the time of construction is widened as much as possible to prevent the stepping crack and the rainwater intrusion prevention effect close to that of the rectangular shape. FIG. 1 shows an example of a flat roof material A, and in FIG. 1, H = 4.
15mm, L = 909mm, h = 80mm, l = 80mm, l ₁
= 10 mm. The shape of the inclined edge portion 2 is not limited to the above. For example, in FIG. 3 (a), l =
80 mm, h = 40 mm, l ₁ = 10 mm, and FIG.
(b) the l = 40mm, h = 40mm, there as l ₁ = 10 mm, FIG. 3 (c) in l = 40mm, h = 80mm, l 1 = 10
mm, and in FIG. 3 (d), l = 120 mm, h = 40 m
m, l ₁ = 10 mm, and in FIG. 3 (e), l = 120 m
m, h = 80 mm, l ₁ = 10 mm. In order to construct the above flat roof material A, the flat roof material A to be constructed next to the lower end of the inclined edge portion 2 of the already constructed flat roof material A is slanted and the lower end portion of the inclined edge portion 2 is slanted. Horizontal edge of
2a are aligned, and both inclined edges 2 are aligned in this state
As shown in FIG. 2 (a), the horizontal edge portion 2a of the lower end portion is pressed by the finger 7 (index finger), and the flat roof material A to be constructed is rotated around the portion pressed by the finger 7 as a center. Flat roof material A
The side edges of are brought together. In this case, since the horizontal edge portion 2a of the lower end portion of the inclined edge portion 2 is pressed by the finger 7, the angle indicated by α in FIG. 4 is smaller than in the conventional case, and when the flat roof material A is rotated, the finger 7 slides smoothly. Without pressing it with your finger 7, you can rotate it.

[Effects of the Invention] In the present invention, as described above, only the shoulders on both upper sides of the rectangular flat roof roof body are obliquely cut to form an inclined edge, and the lower end of the inclined edge is formed. Is a narrow horizontal edge, and the horizontal edge is located above the upper end of the exposed part of the flat roofing material, so the shoulders of the flat roofing materials are put together and the flat part is pressed with your finger. When the roof material is rotated and installed, the flat roof material can be reliably rotated and installed without the fingers slipping. In particular, since the horizontal edge is provided at the lower end of the inclined edge, by touching the finger on the horizontal edge, the finger may slip at the angle between the horizontal edge and the inclined edge. In this case, the length of the horizontal edges is about 10 mm, so the total length of adjacent horizontal edges is about 20 mm when aligning with your finger, which is just an adult. The width of the fingers is slightly wider than that of the fingers, so that the fingers are prevented from sliding sideways during the positioning work using the fingers, and the positioning work using the fingers can be easily performed. Moreover, in order to improve the workability by providing the inclined edges in this way, since the inclined edges whose lower end is the horizontal edge are formed only on the shoulders of the rectangular flat roof material, Since the original shape is retained, it has the advantages of the rectangular flat roofing material, that is, the overlapping area can be widened to prevent trampling and rainwater intrusion. Further, when the shoulder portion of the flat roofing material is grasped by the other hand, this portion is inclined not at a right angle, so that it is easy to grasp by the hand. Furthermore, when the flat roofing materials are rotated and arranged side by side, the horizontal edges do not align with each other if they are slightly misaligned in the vertical direction. Even in such a case, the position can be easily adjusted by placing a finger on the horizontal edge and shifting the flat roof material in the vertical direction.
