Description

 The invention relates to the construction and can be used when installing a metal roof.

 A known design of the element of the cornice edge of the roof, consisting of a cornice overhang located under the row cover and a flap with an apron located under the cornice overhang and a gutter located under them and attached to the wall (UK application N 2194565, E 04 D 13/15, 1988 )

 The closest in technical essence is the design of the cornice edge of the roof, consisting of a cornice overhang, a wall gutter and an ordinary cover (Smirnov P.N. Roof content. - L .: Stroyizdat, 1975, p.77). In FIG. 1 shows a schematic illustration of the design of the cornice edge of the roof.

 Crutches 2 are attached to the lower edge of the lathing 1, on which a picture of the eaves overhang is attached 3. On top of the picture of the eaves overhang with a given slope, hooks 4 are mounted, on which the picture of the wall trough 5 rests. The upper edge of the picture of the wall trough is connected to the row cover picture 6.

 When assembling the painting of an ordinary covering, a standing single fold 7 was used, and when assembling a picture of a wall trough, paintings of a wall overhang and a connection of a wall trough with an ordinary coating were used as a double lying fold 8. All the roof paintings were attached to the crate with 9 clasps.

 This design has the following disadvantages.

 The complexity of the design and the great complexity of the work associated with the manual preparation of the elements of the picture of the eaves overhang and the wall gutter and manual connection using a double lying fold.

 The inability to use modern roofing steel with a plastic coating without destroying this coating when performing manual joining of paintings using a double lying fold. As a result, the service life of the roof is sharply reduced, there is no maintainability of the roof, since even slight damage to the eaves of the roof or wall gutter necessitates the complete replacement of a significant area of the roof area.

 The objective of the invention is to remedy these disadvantages, increase the manufacturability of the assembly of the wall gutter, increase the service life and increase maintainability of the roof.

 The problem is solved as follows. The design of the eaves edge of the roof consists of an ordinary coating and a wall gutter, an ordinary coating is made of paintings connected by a double fold. The wall trough is made as an overhead in the form of a hollow prism. An elastic gasket is installed between the wall trough and the row cover, which is covered with a layer of sealant on both sides. At the installation location of the wall chute, the double folds connecting the paintings of the row cover are made lying, between the roof crate and the row cover there is a backing plate, to which the wall chute is attached through an elastic gasket and the row cover using self-tapping screws.

 An additional eaves overhang can be installed under the ordinary coating, with the wall chute attached to the roof lath through an elastic gasket, an ordinary coating, the eaves overhang and the underlay plate.

 The wall chute is made collapsible and consists of a frame, front and rear shields. The front flap covers the front (with respect to flowing water) and the lower edges of the wall groove frame, and the rear flap - the rear face of the frame.

 The invention meets the criteria of "novelty" and "materiality of differences", as a new design of the eaves edge of the roof has been developed, which ensures the achievement of a higher technical result.

 The service life of the eaves of the roof increases due to the rigid connection of the roof elements and the wall trough and prevents the destruction of the structure under the adverse effects of the atmosphere and temperature extremes. The developed design allows you to remove and repair individual elements.

 In FIG. 2 schematically shows the design of the eaves edge of the roof, where 1 is the roof lathing, 2 is the row cover pattern connected by a double fold 3, 4 is a wall chute consisting of a front shield 5, a frame 6 and a rear shield 7. The wall chute 4 is mounted on the gasket 8 of elastic material having a sealant layer 9 on both sides, under the ordinary coating 2 along the axis of the wall groove 4, a backing plate 10 is installed on the roof crate, the elements of the wall groove are interconnected and attached to the backing plate 10 by self-cutting x screws 11. The double folds 3 pictures ordinary coating 2 at the fixing trough wall formed immobile.

 The paintings of the ordinary cover 2 are mounted on the crate of the edge of the roof 1 using crutches 12.

 In FIG. 3 schematically shows the design of the eaves edge of the roof, where 1 is the roof lathing, 2 are the paintings of the ordinary coating, connected by a double fold 3, 4 is the wall gutter. The wall chute 4 is mounted on a gasket 8 made of elastic material with a sealant layer 9 on both sides, a picture of the eaves 13 is installed under the row cover 2, a lining plate 10 is installed under the picture of the eaves 13 along the axis of the wall chute 4, the wall chute 4 attached to the backing plate 10 using self-tapping screws 11. Double folds 3 of the paintings of the ordinary coating 2, in the place of attachment of the wall gutter made lying.

 The picture 13 of the eaves overhang is mounted on the crate of the edge of the roof 1 with the help of crutches 12. The double fold 3 in the place of fastening the wall trough is made lying.

 A method of assembling the cornice edge of the roof is as follows (figure 2). Crutches 12 and a backing plate 10 are attached to the roof crate 1, installing it along the supposed axis of the wall trough; on the crutches 12, paintings of an ordinary cover 2 are attached, which are interconnected using a double standing fold. In the place of attachment of the wall groove 4, these folds are heaped up, that is, turned into lying ones. A layer of sealant 9 is applied to the elastic gasket 8 on both sides and installed on an ordinary coating 2. On the gasket with a sealant layer, the front shield 5 of the wall groove 4 is placed. The frame 6 is inserted into the front shield 5, and then the back shield 7 is hung on the front shield 5 . All elements of the wall chute fasten with self-tapping screws 11.

 When using the eaves overhang pattern in the roof structure (Fig. 3), after installing the backing plate 10 on the crutches 12, the eaves overhang 13 is fixed, and then the lap over the eaves overhang 13 is installed, the paintings of the ordinary cover 2, which are interconnected using a double standing rebate. In the place of attachment of the wall groove 4, these folds are heaped up, that is, turned into lying ones. A layer of sealant 9 is applied to the elastic gasket 8 on both sides and installed on an ordinary coating 2. A wall chute 4 is placed on the gasket with a sealant layer, which is fastened with self-tapping screws 11 to the backing plate 10, through the elastic gasket 8, paintings of the ordinary coating 2, picture eaves overhang 13.

 The manufacturability of the cornice edge assembly is increased in comparison with the prototype of the roof due to the mechanization of joining the patterns of the ordinary coating and the unification of the structural elements of the wall gutter, the simplicity of its assembly and installation. The maintainability of the structure is high, since the wall chute is made collapsible, and any element of the wall chute can be removed and repaired. The method of assembling the eaves edge of the roof ensures no damage to the coating of the roofing steel, which ensures a long service life of the roof.

 In addition, the design of the wall gutter is such that it is easy to place a heating electric cable inside the wall gutter to prevent icing of the eaves of the roof, while the heating cable is reliably protected from damage.
