Description

[Detailed explanation of the idea] [Industrial application field] This idea relates to a snow stopper structure on a roof.

[Conventional technology]

In regions with heavy winter snowfall, snow stoppers A as shown in FIG. 3 are distributed at appropriate locations on the roof in order to prevent the snow accumulated on the roof from falling naturally.

[Problems with conventional technology]

The above-mentioned snow stopper fitting A is generally formed by bending a thin metal plate, and has a fixing part A1 on the roof field surface;
It consists of an extending part A2 reaching the surface of the roofing material and a folded piece A3 for blocking snow, but since the extending part A2 is inserted between the upper row roofing material B1 and the lower row roofing material B2, the thickness T There is a difference in level due to the roof material B.
There was a problem that tread cracks were more likely to occur.

However, in order to solve this problem, the extension part A
Although it would be possible to reduce the thickness of 2, there is a limit to its durability against snow loads, and at present it is not possible to take sufficient measures against cracks.

[Problems solved by invention]

This invention was devised in view of the above-mentioned problems, with the aim of obtaining a snow stopper structure on a roof that does not impair the strength of the snow stopper fittings and does not cause cracks in the roofing material.

〔Example〕

Next, this invention will be explained using examples.

Figure 1 is a perspective view of the main parts of an embodiment of this invention;
The figure is a perspective view of the snow stopper of this invention.

In the snow prevention structure on the roof of this invention, some of the roofing materials arranged in horizontal rows of the roofing materials 1 are cut into strips (3 in the figure) at their lateral butting ends 2, and the roof field surface is A strip plate 5 with an upper end 5A fixed to the strip is fitted into the cut strip and placed with its lower end 5B exposed on the surface of the lower row roofing material 1, and the lower end 5B of this strip plate 5 is folded upward to form a snow stopper piece 5C. It is structured as follows.

In the above, the thickness T of the strip plate 5 does not need to be larger than the thickness of the roofing material 1, and therefore, taking into consideration the snow load and the thickness of the roofing material 1, the thickness T can be set to 2 to 3 mm. It is.

Further, the shape of the upper end 5A of the strip plate 5 is made to follow the contour shape of the butt portion of the roofing material 1,
Mutual adhesion is improved.

Note that 6 in the figure indicates a fixed nail.

[Function] In this invention, since the strip plates 5 are arranged parallel to each other in a plane between the roofing materials 1, 1, no protrusion is formed on the upper row of roofing materials 1, and no local stress is generated.

Furthermore, since the thickness of the strip plate 5 can be increased within a range that does not reach the thickness of the roofing material 1, sufficient strength can be achieved.

〔effect〕

This idea is structured as above, so
It completely eliminates the problem of snow stoppers causing cracks in roofing materials, has strong durability, and is convenient to supply and use if the roofing material and band-like metal fittings are included as a set. It has various practical effects such as being easy to implement.
