Abstract

PURPOSE:To economize the labor in the processing for snow by constituting a snow fall roof structure from an upper stage slope surface having a prescribed angle slope of a roof surface towards an eaVes from a ridge, lower stage slope surface which is continuous to the upper stage slope surface and has 3 (height)/10 (eateral length) slope and a parabola shaped curved surface forming the eaves. CONSTITUTION:A natural advance type vertical snow dropping roof is formed from an upper stage slope surface 1 having a slope of 45 deg. of a roof surface towards an eaves from a ridge, lower stage slope surface 2 which is continuous to the upper stage slope surface 1 and has the slope ranging from 2/10 slope to 3/10 slope and a parabola shaped curved surface 3 continuous to the lower stage slope surface 2. When a certain quantity of heaped snow is generated by snow fall, the natural advance vertical snow fall structure (a) permits the slip fall of the roof snow on the upper stage slope surface 1, and the roof snow on the lower stage slope surface 2 is pushed out, and the dynamic friction is induced on the roof snow, and the roof snow is gradually shifted by the composite force with the self sliding-out force on the lower stage slope surface 2, and even if the direct drop-down type snow fall at a nearly uniform speed is generated, snow is discharged vertically from the curved surface 3 at the eaves. If a temperature keeping member is laid on the whole surface of the undersurface of a roof plate made of metal, natural snow fall is generated, keeping the frictional coefficient nearly constant, and freezing and the generation of ice pillar are prevented.

ものである。2. Description of the Related Art As for the present state of roof snow treatment for a roof structure to which the present invention is applied, a technique such as a treatment by sliding snowfall with a steep roof surface or a treatment by a sliding roof snowfall at any time is proposed. However, in the former Tongari structure with a steep slope, the frequency of snowfall is high, and the slipping out of the structure causes it to fly out, which requires a lot of space with the next house and also requires measures to prevent snow accumulation. However, the latter circular roof structure is adopted for school gymnasiums and large stadiums, and is not suitable for general housing.

As shown in FIG. 1, the roof surface has an upper slope surface 1 with a 45 ° slope from the ridge toward the eaves, and a three-dimensional slope surface continuous with the upper slope surface 1. It is composed of a lower sloped surface 2 and a parabolic curved surface 3 which continuously forms an eave tip on the lower sloped surface 2.

ものである。In the naturally propelled vertical snowfall roof structure a (hereinafter, simply referred to as the snowfall roof structure a) constructed as above, when a certain amount of snow is accumulated due to snowfall, the roof snow on the upper slope surface 1 slides down, and the lower slope surface. The roof snow on the surface 2 is pushed out, dynamic friction is induced in the roof snow, and the roof snow gradually moves due to the combined force with the self-sliding output on the lower slope surface 2, resulting in a direct snowfall at a substantially uniform speed. It is removed vertically from the curved surface 3 of the eaves.

It is very safe, and because it is vertical snowfall, it does not pose a risk to adjacent houses at narrow intervals and realizes roof snow treatment for general houses. If a heat insulating material is laid on the entire bottom surface of the metal roof plate, the contact temperature between the snow cover and the roof surface can be maintained at about the same as during the daytime even during snowfall at night, so that the friction coefficient can be kept substantially constant, and Natural snowfall can be performed with rhythmic continuity regardless. Therefore, there is no room for freezing and no icicles are generated.
