Definitions
- the invention relates to a method for producing a one-piece gutter bracket provided with beads and water seams for the connection of box-shaped gutters to side walls designed in the shape of a circular arc in the corner region of the gutter bracket pieces, in particular according to DIN 18461.
- Box gutter brackets for the connection of box-shaped roof gutters are made from two mutually abutting box gutter sections, which are miter cut at the joint, by means of conventional soldering or welding of the connection point running in the miter direction.
- Such a production involves a considerable amount of material and time for the soldering or welding and for the miter cutting of the box gutter pieces.
- the long-term tightness of the connection point is also not guaranteed, because there are deposits of dirt which lead to corrosion.
- the bending rigidity of this conventional box gutter angle is not sufficient for a number of applications, its shape does not meet the aesthetic requirements for contemporary facade design of buildings.
- EP-A 0 078 584 describes a one-part gutter bracket provided with beads and water seams for connecting semicircular gutters, which is designed in the shape of a circular arc in the corner region of the gutter brackets.
- the forming direction of the outlet board for the gutter angle is diagonal to the rolling direction of the square or rectangular board with four corner cuts.
- the beads and water seams are simultaneously formed in a straight line on the gutter elbows by bending in one operation.
- the beads abutting against each other at an acute angle in the corner area merge into a circular-shaped edge in the circular edge of the gutter angle and the transverse edges of the water seams in the corner area merge into an externally formed crescent-shaped intermediate piece.
- the board shape used for such a gutter angle is not suitable for the production of box-shaped gutter angles, since the wall thickness is uneven, particularly in the area of the open leg ends, and cracks can form in this area.
- the object of the invention is therefore to provide a box gutter angle which can be produced without the use of component connections, in particular soldering and welding, which has an improved flexural rigidity, in which there are no signs of corrosion and which meets the aesthetic requirements with regard to the contemporary facade design of buildings.
- a pentagonal non-ferrous metal plate in particular a zinc plate, the plane of symmetry of which is perpendicular to the rolling direction and whose four sides, two of which are each of equal length, are drawn diagonally and one side of which runs parallel to the rolling direction, whereby the forming direction of the corresponding board sections runs diagonally to the rolling direction of the board, the beads and water seams are formed in a straight line on the gutter elbows by bending and the beads abutting against each other at an acute angle in the corner area to form a triangular aperture in the circular edge of the gutter angle and the transverse edges the water seams in the corner area merge into a crescent-shaped intermediate piece formed on the outside.
- the radii of the rounded corners between the legs have approximately the same size.
- the free overhanging edges of the deep-drawn box gutter angle are trimmed so that both the beads and the water seams can be produced simultaneously by bending in one operation.
- the box gutter angle according to the invention can be simplified by deep drawing from a suitably shaped sheet metal blank that has the same service life as the associated box-shaped hanging roof gutters, that has improved bending rigidity and that meets the aesthetic requirements currently made with regard to modern facade design.
- FIG. 1 shows the zinc sheet blank (2) to be used for the production of the box gutter angle, punched out of a strip (1) produced by rolling, which has a pentagonal shape with a plane of symmetry (3) perpendicular to the rolling direction, the four sides (4, 4 ', 5, 5'), two of which are of equal length, diagonal and one side (6) parallel to the rolling direction.
- the rectilinear beads (8, 9) collide in the rounded corner region between the legs (10, 11) to form an approximately triangular diaphragm (12), which merges into the circular arc-shaped upper edge of the side wall of the box gutter bracket (7).
- the rectilinear water folds (13, 14) merge in the rounded corner area of the legs into a crescent-shaped intermediate piece (15) formed on the outside.
- Fig. 3 is formed as an inside angle, made by deep drawing box gutter angle (16), in which in the ends of the straight executed beads (17, 18) in the rounded corner area between the legs (19, 20) a same radius as the corner area having bead (21) is screwed, which rests with its free longitudinal edge on the inside of the box gutter angle (16).
- the straight water folds (22, 23) overlap in the rounded corner area between the legs (19, 20).
