Description

 The invention relates to building structures, in particular to structures of cornice units of buildings.

Known eaves roof overhangs, which are used to place drainage devices (trays, gutters, drains and funnels) and to prevent water and snow from falling onto the outer surface of the walls [1]
The disadvantage of this design is the low reliability of the protection of the edge of the roof in the upper part of the wall from operational influences. Due to the sharp pressure drop on the outer edge of the roof, an airflow swirls, which leads to intense snow deposition in the form of a “tongue” in contact with the wall. When snow blowing melts, the upper part of the wall is soaked and the frosty weathering of its outer layer is intense. As the thickness of the snow blow increases, it collapses, the outer edge of the overhang of the roof breaks and the broadened upper part of the wall deforms. With manual cleavage of icicles formed on the eaves overhang, the hard outer edge is destroyed. Ice growths, the freezing of gutters, funnels, pipes prevents drainage from the eaves.

Also known is the design of the polymer drainage gutter to avoid clogging of the cross section with leaves and debris [2]
The disadvantage of this design is the freezing of the cross section in winter conditions, which leads to transfusion of water through the eaves overhang and to the soaking of the upper part of the wall.

Closest to the invention, the technical solution is a device for removing snow and ice from the eaves overhang of the roof, containing a hanging element closed in cross section fixed to the outer edge of the roof [3]
A common feature of the prototype and the proposed device is the presence of an elastic and closed in cross section element hanging from the outer edge of the roof. However, the known solution does not exclude the possibility of snow deposition on the outer edge of the roof and the formation of a snowy "tongue" on the upper part of the wall. In the spring, during thawing of the accumulated layer of snow, it collapses with deformation and destruction of the cornice assembly. The energy consumption for the operation of the heating element increases operating costs.

 The objective of the invention is to reduce the size and self-dropping of snow blowing, which ensures a reduction in operating costs for cleaning the cornice from snow and ice.

 This is achieved by the fact that in the device for removing snow and ice from the eaves of the roof of the roof, containing a hanging element fixed in the cross section fixed to the outer edge of the roof, said element is made in the cross section in the form of a drop-shaped contour.

 Figure 1 shows a transverse section of the eaves overhang with a hanging element during the growth of a crack of snow blowing; in Fig.2 the same, after self-resetting snow blowing.

 A device for removing snow and ice from the eaves of the roof contains a hanging element 1 made elastic in the form of a closed contour of a drop-shaped shape in cross section. The upper (narrow) part of the hanging element 1 is attached to the outer edge of the roof 2, which at the same time rests on the widened upper part of the wall 3. Element 1 is made, for example, of a rubber fabric (conveyor belt) or cold-resistant polymer. In this case, the element 1 takes a drop-shaped streamlined shape under the action of its own weight.

 The device operates as follows.

 With increasing thickness of the snow blow 4 on the outer surface of the element 1 (figure 1) due to the elastic deformation of this element, the latter bends down. As a result, the snow inflation 4 self-reset, after which the element 1 due to its elasticity restores its normal shape (figure 2). This eliminates the soaking and destruction of the upper part of the wall 3. In addition, the element 1 eliminates the sharp edge of the roof 2, thereby reducing the rarefaction and turbulence of the air flow 5, which greatly complicates the formation of snow blowing 4 and icicles (not shown) when moving to a positive temperature. When manually cleaning the roof 2 from snow and chipping icicles from the edge or when snow slides off the overhang of the roof due to the elasticity of the element 1, the outer edge of the roof 2 does not collapse from shock and bending influences. In addition, this device allows you to place the drain funnels on the outer edge 2 due to local elastic deformation of the element 1, which ensures reliable drainage from the overhang of the roof.

 Inside the cavity of the element 1 can be placed heating devices to remove snow and ice. This solution improves the protection of heating devices from precipitation and accidental destruction when cleaning the roof from snow and ice.

 The use of a hanging closed flexible element 1 in the device, which has a drop-shaped streamlined shape due to the elasticity of the material in the cross section, reduces the possibility of snow blowing 4 and icicles during transition to a positive temperature, which increases the reliability of operation of the eaves of the roof from the top of the wall 3. Possibility of self-dropping snow blowing 4 reduces operating costs compared with the prototype.
