GUTTER ASSEMBLY UNIT, PARTICULARLY FOR A BUILDING WITH A ROOF WITHOUT EAVES

Description

[0001] The subject of the invention is a gutter assembly unit used in a drainage system for a roof, balcony or building terrace of which the front edge of the gutter extends out over the facade, particularly for a building with a roof without eaves.

[0002] Known gutter assembly units have hook-shaped attachment brackets with a U-shaped cross section girding the gutter in the web, with flanges directed external to the cross section. In buildings with a roof without eaves where the drainage system of gutters and downspouts is frequently contained internal to a layer of thermal insulation, the gutters are shielded with a cover attachment suspended on the front edge of the gutter and obscuring them substantially in the plane of the building facade. One of the solutions for the design conditions equivalent to those with a roof without eaves is presented in the German patent application specification DE29714562U by the example of the construction presented in Fig.3. A drainage system for a balcony slab or terrace includes a drip plate, gutter brackets connected to the front surface of the slab or the external building wall, a gutter with a right-angled-box cross-section and a cover attachment mounted on the external shoulder of the gutter. The solution uses components made of aluminum channels and is technically complex. Hook-shaped gutter brackets of the most commonly used construction are U-shaped, with flanges directed external to the cross section girding the gutter in the web, for example as according to the utility model PL 64347Y.

[0003] In the rear segment, flush to the attachment surface the flanges have mounting members bent outwardly with mounting holes. The gutter is located between a rim inwardly bent from the rear wall of the web and the outwardly curved front rim of the bracket contiguous to the curved front edge of the gutter.

[0004] DE 101 18 227 discloses a gutter assembly unit according to the preamble of claim 1.

[0005] According to the present invention the gutter assembly unit comprises the features of claim 1. It is similar to the above description, with a U-shaped, hook-shaped bracket with flanges directed external to the cross section, which web locates the gutter between a rim inwardly bent from the rear wall of the web and the outwardly curved front rim of the bracket. The cover attachment is suspended on the curved front rim of the gutter. The essence of this solution is based on the fact that the bracket has attachment grooves on the bottom edge of the flanges in the area behind the lower front bend, directed at a sharp angle downward to the rear and the cover attachment has a front face of a height greater than the height of the bracket and an oblique face bent away from the lower edge in from below the bracket upward. The oblique face is finished with a catch which enters the attachment grooves by elastic deformation.

[0006] It is advantageous for the oblique face of the cover attachment to be bent longitudinally in the central area creating a cross section in the shape of a broken line, the rear section of which is perpendicular to the front face of the cover attachment in the position of the catch.

[0007] It is also advantageous to create the bracket with a rear tongue in the form of a strip of sheet metal welded to the rear surface at the end of the web. The solution guarantees easy mounting of the cover attachment, which is attached to the bracket by elastic deformation, at the same time rending the gutter area favorable architectural aesthetics.

[0008] The assembly unit solution according to the present invention is illustrated by the description of sample constructions shown in the drawing, in which Fig. 1 presents a cross section of the gutter assembly unit with a right-angle-box profile, Fig.2 and Fig.3 successively are perspective views of the cover attachment and bracket, Fig.4 a cross section of the gutter assembly unit with a semi-circular profile, while the following Figures 5 and 6 present the cross-section and cover attachment of another gutter assembly unit, used for a roof without eaves, where the front curved rim of the gutter is located higher and beyond the upper edge of the building facade.

[0009] Sample unit constructions presented in Figures 1, 2 and 3 have been adjusted to-the conditions of a building with a roof without eaves where the outer wall is covered with a layer of insulation 10 and a layer of plaster facade 9 - with a total thickness greater than the width of the gutter R. Drainage water drips from the roof to the gutter R via a drainage plate, not visible in the drawing. The location of gutter R with a right-angled-box cross section is set by brackets U, attached to a wooden or plastic fascia board under the roof allowing for the anchoring of the U bracket via screws through the holes in mounting members 7. The bracket U has the shape of a hook of dimensions designated by the gutter channel R, and is formed from sheet steel in a U cross section that girds the gutter R in its web with flanges directed externally. Gutter R is set in bracket U between the rear tongue 1 in the form of a strip of sheet metal welded to the rear surface at the end of the web. The rear tongue 1 is bent by hand to the rear edge of the gutter R after its mounting into location in bracket U and resting on the curved front rim at the front end 2 of the bracket U. Bracket U has attachment grooves 3 on the bottom edges of the flanges of the web in the area behind the lower front bend, directed at a sharp angle α downward to the rear. The cover attachment M is suspended on the curved front rim of the gutter R, and has a front face 4 of a height H greater than the height h of the bracket U and an oblique face 5 bent away from the lower edge in direction from below the bracket U upward and finished with a catch 6. The oblique face 5 is bent longitudinally in the central area creating a cross section in the shape of a broken line, the rear section of which is perpendicular to the front face of the cover attachment M at the position of the catch 6. After having suspended the cover attachment M on the front rim 2, by pressing the lower end of the front face 4 the assembler causes the elastic deformation of the bracket U and the insertion of catch 6 into the attachment groove 3 of the cover attachment M. Holes 8 are located in the outwardly curved front rims 2 of the brackets U, through which holes - in the final assembly operations - cover attachment M and gutter R are fixed with tubular rivets.

[0010] The assembly unit solution shown in Figure 1, 2 and 3 may also be used in the situation of a roof with eaves, gutters of a semicircular profile and assembly of brackets U directly to the element constituting the facade of the building - which, for example, is illustrated in Fig.4.

[0011] The example of the gutter assembly unit illustrated in Fig.5 differs from the above-described installation conditions. Gutter R is located above and behind the upper edge of the facade 9. The cover attachment M shown in Fig.6 has a cross-sectional shape determined by the front face 4 connected to the upper curved rim, finished with corner 11. The oblique face 5 is bent in corner 11 toward the facade 9 and is finished with a supportive section 12 with externally bent drip edge. Cover attachment M and gutter R are fixed with tubular rivets 8 to the front rims of the brackets U.
