DE102007032989B3 - Deep-drawn gutter interior angle - Google Patents

Abstract

A deep-drawn gutter-inner angle made of sheet metal has two legs (1, 2), the building-side edges (1.1, 2.1) are bent to a Wasserfalz (1.2, 2.2) and in the direction of the building side corner (3) in each case pass a sheet metal strip. In order to increase the dimensional stability of the gutter inner angle, each of the sheet metal strips (1.3, 2.3) in the region of the corner (3) to a flag (1.4, 2.4) widened and the two flags are integrally connected.

Description

The The invention relates to a deep-drawn gutter interior angle with the features specified in the preamble of claim 1.

since Roof gutters are known for a long time, predominantly 90 ° angles, which consist of two mitred gutter sections, soldered in the corner joint or are welded. In the area of the inner corner, so the later building side corner, is often a separately manufactured fitting usually essentially triangular outline or a sheet metal strip for further stiffening soldered. Such gutter interior angles are very dimensionally stable, but manufacturing technology consuming and therefore have relatively high production costs.

With lower manufacturing costs can be for some years gutter interior angle made from a single blank by deep drawing. These Gutter interior angles, however, are less dimensionally stable, because the corner-side Ends of the respective Wasserfalze extending metal strips not together are connected but at most overlap. An additional Stiffening means of a welded or soldered fitting or Bandes would However, the cost advantage of deep drawing largely ruined.

Of the Invention is based on the object, a deep-drawn gutter interior angle to create with improved dimensional stability.

These Task is inventively by the achieved in claim 1 features.

advantageous embodiments and further developments are the subject of the dependent claims.

Of the Gutter interior angle according to the invention will be described below the one embodiment illustrative drawing explained. It shows:

1 a perspective view,

2 the appropriate blank after deep drawing with marked cutting or punching lines.

The gutter inside angle in 1 has two mutually perpendicular legs 1 and 2 , Their building edges 1.1 , and 2.1 are each directed to the gutter inside Wasserfalzen 1.2 and 2.2 bent. These waterfalls go towards the building's corner 3 in each case a metal strip 1.3 respectively. 2.3 above. These metal strips 1.3 respectively. 2.3 are on the respective, building-facing edge with the Wasserfalzen 1.5 respectively. 2.5 the thigh 1 respectively. 2 directed, so are in the installed state of the gutter interior angle substantially in the same, approximately horizontal plane.

Each of the metal strips 1.3 respectively. 2.3 is in the area of the corner 3 to a flag 1.4 respectively. 2.4 widened. The flag 1.4 overlaps the flag 2.4 , The two flags are in their overlap area 4 integrally connected to each other by one of the usual methods, ie z. B. welded, soldered or enforced (clinched).

When the mutually facing, end edges of the flags 1.4 and 2.4 at least approximately parallel (as shown), the flags need not overlap. It is sufficient if these flag edges butted against each other and welded or soldered in the joint.

2 shows a bottom view of the raw form of the gutter inside angle after deep drawing from a corresponding blank. From this raw form, a blank is produced in the next step by punching along the dashed line, whose edges to the in 1 shown folds are bent, the areas 1.4 respectively. 2.4 in 2 the later, overlapping flags 1.4 respectively. 2.4 in 1 correspond.
