Abstract

1. Method for producing an integral gutter angle member (1) for the connection of semicircular gutters by deep-drawing from a blank of nonferrous metal, particularly of zinc, comprising beads (2, 3) and water flanges (7, 8) and having side walls with the shape of an arc of a circle at the corner at which the leg portions (4, 5) of the angle member merge, wherein the portions of the blank forming the leg portions of the gutter angle member have been shaped in a direction diagonal to the direction in which the blanks has been rolled, characterized in that the beads (2, 3) and water flanges (7, 8) will be formed straight-lined at the leg portions (4, 5) of the gutter angle member, wherein the beads meeting at the corner by an acute angle merge into the circular edge of the gutter angle member (1) by forming an approximately triangular blind (6) and the transverse edges of the water flanges merge near the corner into a crescent-shaped intermediate portion (9) formed on the outside.

Description

Oppfinnelsen vedrører en fremgangsmåte til fremstilling av en med vulster og vannfalser forsynt, enhetlig og for forbindelse med halvrunde takrenner beregnet takrennevinkel med i takrennevinkelbenenes hjørneområde sirkelbueformede sidevegger, fremkommet ved dyptrekking av et ikke-jern-metall-emne, særlig et sinkemne, idet omformingsretningen til de respektive emneavsnitt går diagonalt på emnets valseretning. The invention relates to a method for producing a gutter angle provided with beads and water seams, uniform and intended for connection with semi-circular gutters, with circular arc-shaped side walls in the corner area of the gutter angle legs, obtained by deep drawing a non-ferrous metal blank, in particular a zinc blank, the direction of transformation to the respective subject sections run diagonally in the subject's rolling direction.

For å unngå den ved fremstillingen av takrennevinkler bestående av to i spiss vinkel til hverandre støtende halvrunde takrennestykker vanlige sveising eller lodding av det i gjæringsretningen forløpende forbindelsessted, for derved å unngå de dermed forbundne betydelige ulemper med hensyn til montering og ønsket langtidstetthet, foreslås det i DE-GM 78 11 514 en takrennevinkel for forbindelse mellom halvrunde takrenner, hvilken takrennevinkel er fremstilt ved dyptrekking av sinkplate, idet sideveggene har sirkelbueform i hjørneområdet. En slik takrennevinkel har imidlertid ikke funnet særlig anvendelse i praksis, fordi den sirkelbueformede utforming, særlig av vulsten, ikke tilfredsstiller de estetiske krav med hensyn til tilpassing til rettvinklede hushjørner. Dessuten vil i mange tilfeller bøyestivheten til en slik takrennevinkel ikke være god nok. In order to avoid the usual welding or soldering of the connection point running in the miter direction in the manufacture of gutter angles consisting of two half-round gutter pieces butting at an acute angle, in order to thereby avoid the associated significant disadvantages with regard to assembly and the desired long-term tightness, it is proposed in DE-GM 78 11 514 a gutter angle for connection between semi-circular gutters, which gutter angle is produced by deep drawing of zinc sheet, the side walls having a circular arch shape in the corner area. However, such a gutter angle has not found particular application in practice, because the circular arc-shaped design, especially of the bead, does not satisfy the aesthetic requirements with regard to adaptation to right-angled house corners. Moreover, in many cases the bending stiffness of such a gutter angle will not be good enough.

Fra DE-A 27 26 607 er det kjent en takrennevinkel fremstilt i ett stykke ved hjelp av dyptrekking, men også denne kjente utførelse anses å ha for dårlig bøyestivhet. From DE-A 27 26 607, a gutter angle produced in one piece by means of deep drawing is known, but this known design is also considered to have too poor bending stiffness.

Det er derfor en hensikt med foreliggende oppfinnelse å for-bedre den innledningsvis nevnte fremgangsmåte derhen at det kan fremstilles enhetlige takrennevinkler som både har den nødvendige bøyestivhet såvel som et av estetiske grunner ønsket, kantet utseende. It is therefore an aim of the present invention to improve the initially mentioned method to the extent that uniform gutter angles can be produced which both have the necessary bending stiffness as well as an angular appearance desired for aesthetic reasons.

Dette oppnås ved en fremgangsmåte som nevnt innledningsvis, med de kjennetegnende trekk som fremgår av krav l's karakteristikk. Med en slik fremgangsmåte oppnår man ikke bare at takrennevinkelen optisk sett får et ønsket kantet utseende, men også at bøyestivheten økes betraktelig på grunn av formen til den trekantede blende og det sigdformede mellomstykke. This is achieved by a method as mentioned at the outset, with the characteristic features that appear in the characteristics of claim 1. With such a method, it is not only achieved that the gutter angle optically acquires the desired angular appearance, but also that the bending stiffness is increased considerably due to the shape of the triangular cover and the sickle-shaped intermediate piece.

Fordelaktig kan radiene til takrennevinkelbenenes hjørne-områder utformes omtrent like store, idet derved takrennevinkelen kan anvendes både for tilveiebringelse av ytter-såvel som innervinkler. Advantageously, the radii of the corner areas of the gutter angle legs can be designed to be approximately the same size, as the gutter angle can thereby be used both for the provision of external as well as internal angles.

Fordelaktig blir de frie utragende kanter av den dyptrukne takrennevinkel beskåret slik at man derav kan tilforme både vulstene såvel som vannfalsene, fortrinnsvis i en arbeidsgang. Advantageously, the free projecting edges of the deep-drawn gutter angle are trimmed so that both the beads and the water folds can be formed from them, preferably in one work step.

Oppfinnelsen skal forklares nærmere under henvisning til tegningene som viser takrennevinkler fremstilt ifølge oppfinnelsen. The invention shall be explained in more detail with reference to the drawings which show gutter angles produced according to the invention.

Ved den i fig. 1 viste, ved hjelp av dyptrekking av et tilsvarende utformet emne fremstilt takrenne-yttervinkel 1, støter de rettlinjede vulster 2,3 på takrenne-yttervinkelstykkene 4,5 slik mot hverandre med en spiss vinkel i hjørneområdet at de under dannelse av en trekantformet blende 6 går over i den sirkelbueformde øvre kant av sideveggen i takrenne-yttervinkelen 1. Tverrkantene til de rettlinjede vannfalser 7,8 på takrenne-yttervinkelstykkene 4,5 går i hjørneområdet over i et utad tilformet sigdformet mellomstykke 9. By the one in fig. 1 showed, by means of deep drawing of a correspondingly designed blank produced gutter-external angle 1, the rectilinear beads 2,3 on the gutter-external angle pieces 4,5 abut against each other at an acute angle in the corner area so that during the formation of a triangular aperture 6 merges into the circular arc-shaped upper edge of the side wall in the gutter-external angle 1. The transverse edges of the rectilinear water rebates 7,8 on the gutter-external angle pieces 4,5 merge in the corner area into an outwardly shaped sickle-shaped intermediate piece 9.

I fig. 2 er det vist en dyptrukket takrennevinkel hvis kanter er beskåret slik at det derav kan tilformes en takrenne-yttervinkel . In fig. 2 shows a deep-drawn gutter angle whose edges have been trimmed so that a gutter outer angle can be formed from it.
