INVENTION
Russian Federation Patent RU2044851
Device for removing snow and ice from the eaves ROOF
Name of applicant: Perm State Technical University
Name of the inventor: VV Belyaev
The name of the patentee: Perm State Technical University

Starting date of the patent: 1993.07.12
Summary of the invention: to reduce the size and samosbrasyvaniya snow blowing device is mounted on the outer edge of the roof 2. The latter rests on a broadened upper portion of the wall 3. The device is hung from the roof edges of two elastic element 1 made in cross-section in the form of teardrop-shaped contour. 2 ill.
DESCRIPTION OF THE INVENTION
The invention relates to building structures, in particular to structures of buildings curtain assemblies.
There are the eaves of the roof, serving to accommodate drainage devices (trays, gutters, drains and sinks) and to prevent the ingress of water and snow on the outer surface of the walls [1]
The disadvantage of this design is the low reliability of the protection of the roof edge in the top of the wall of operational influences. Due to the sharp pressure drop across the outer edge of the roof swirling airflow occurs, which leads to intensive snegootlozheniyu as "language" in contact with the wall. When melting snow blowing occurs soak the top of the wall and intense frost weathering its outer layer. With an increase in the thickness of the snow blowing his collapse occurs, open the outer edge of the eaves of the roof and the deformation of the broadened top of the wall. In manual chipping icicles forming on the eaves, it is the destruction of a rigid outer edge. Accumulation of ice, freezing of drainage trays, funnels, pipes prevents drainage eaves.
Known and gutter design of the polymer, which avoids clogging of the cross section of leaves and debris [2]
The disadvantage of this design is a sectional freezing winter conditions, leading to transfusion of water through the eaves to soak and top of the wall.
The closest technical solution to the invention is a device for removing snow and ice from the eaves of the roof, comprising mounted on the outer edge of the roof overhangs the closed cross sectional element [3]
A common feature of the prototype and the inventive device is the presence of hanging from the outer edge of the roof closed and a resilient cross-sectional element. However, the known solution does not preclude snegootlozheniya the outer edge of the roof and the snow formation "language" on top of the wall. In the spring when thawing of accumulated snow layer is its failure to deformation and destruction eaves node. Energy consumption for operation of the heating element increases the operating costs.
The task of the invention decrease the size and samosbrasyvanie blowing snow, which ensures reduced maintenance costs to clean up the cornice of snow and ice.
This is achieved in that the device for removing snow and ice from the eaves of the roof, comprising mounted on the outer edge of the roof overhangs the closed cross-sectional element, said element is in cross-section in the form of teardrop-shaped contour.

Apparatus for removing snow and ice from the eaves of the roof comprises a hanging element 1 formed as a closed resilient loop, drop-shaped in cross section. Top (narrower) part of the hanging element 1 is attached to the outer edge of the roof 2 which in this case is based on a broadened upper portion of the wall 3. The element 1 is made for example of rubber-web (conveyor belt) or cold-resistant polymer. When the element 1 receives this teardrop faired under its own weight.
Device operates as follows
With an increase in the thickness of the snow blowing 4 on the outer surface of the element 1 (1) due to the elastic deformation of the element the last bend down. As a result, snow inflating selfresetting 4, after which the element 1 due to its elasticity restores normal form (2). This eliminates the soaking and destruction of the top of the wall 3. Furthermore, the element 1 eliminates the sharp edge of the roof 2, thereby reducing the negative pressure and airflow vortex 5, which greatly hinders the formation of blowing snow and icicles 4 (not shown) at the transition to a positive temperature. For manual cleaning of the roof 2 from snow and icicles from the edge of the shearing or slipping snow from the eaves of the roof due to the elastic element 1, the outer edge of the roof 2 is not destroyed by the shock and bending effects. In addition, this device allows you to place a funnel drain on the outer edge 2 by local elastic deformation element 1, which ensures reliable drainage from the roof eaves.
Inside the cavity of the element 1 can be placed heating device for removing snow and ice. This solution improves the protection of the heating device from rain and accidental destruction when cleaning roofs from snow and ice.
Application of the device hanging endless flexible element 1, due to the elasticity of material having a cross sectional streamlined teardrop shape reduces the possibility of blowing snow and icicles 4 at the transition to the positive temperature increases operating reliability than the eaves of the roof and with the top of walls 3. Ability samosbrasyvaniya blowing snow 4 lowers operating costs compared to the prior art.
CLAIM
DEVICE FOR REMOVING snow and ice from the eaves of roofs, comprising an outer edge fixed to the roof overhangs the closed cross-sectional element, characterized in that said element is in cross-section in the form of teardrop-shaped contour.
