Description

DK 159563 BDK 159563 B

Nærværende opfindelse vedrører en bærende pladeprofil, navnlig 5 til ydertags- eller bjælkelagskonstruktioner med derpå anbragt isolering, ydre tagdækning eller lignende ydre dækning, hvilken profil omfatter en øvre flange, der ved dens kanter går over i to i profilens brugsstilling nedadgående kropsflanger, der begge har afstivninger, hvilke kropsflanger ved deres ned-10 re kant går over i en udadbøjet, nedre flange, idet den øvre flange er betydeligt bredere end de nedre flanger og har et langsgående, afstivende knæk dér, hvor den møder hver af kropsflangerne.The present invention relates to a bearing plate profile, in particular to outer roof or beam layer structures having insulation, outer roofing or similar outer covering, which profile comprises an upper flange which, at its edges, extends into two downwardly flanged body flanges of the profile. stiffeners, which body flanges at their lower edge transition into an outwardly bent lower flange, the upper flange being considerably wider than the lower flanges and having a longitudinal, stiffening crack there where it meets each of the body flanges.

15 En ofte anvendt teknik til rejsning af tage består i på de såkaldte hoveddragere med passende centerafstand at arrangere tværåse. På disse åse anbringer man derefter metalplade, isolering og selve tagdækningen i den nævnte rækkefølge.15 An often used technique for erecting roofs is to arrange transverse rails on the so-called main beams with appropriate center distance. On these ridges are then placed metal plate, insulation and the roofing itself in the order mentioned.

20 I de senere år er der udviklet bærende profiler i ét stykke, som på én gang udgør både ås og metalplade. En sådan bærende profil er beskrevet for eksempel i SE fremlæggelsesskrift nr. 390.045, hvor profilen omfatter en øvre flange, to skrånende kropsflanger og to nedre flanger. Den øvre flange har dels 25 tværgående, afstivende vulster, såkaldte prægninger, og dels langsgående vulster, som er anbragt på hver side af de tværgående prægninger.20 In recent years, one-piece supporting profiles have been developed, which at one time constitute both ridge and sheet metal. Such a supporting profile is described, for example, in SE Patent Specification No. 390,045, wherein the profile comprises an upper flange, two inclined body flanges and two lower flanges. The upper flange has 25 transverse, stiffening beads, so-called embossments, and partly longitudinal beads, which are arranged on each side of the transverse embossments.

Denne kendte bærende profil er imidlertid vanskelig at frem-30 stille, navnlig de tværstillede prægninger i den øvre flange. Tilvejebringelse af både tværgående og langsgående afstivningsvulster eller knæk i en profil af denne type er naturligvis mere kompliceret og derfor dyrere, end hvis profilen alene er forsynet med langsgående afstivninger. Når der i pladen la-35 ves tværgående prægninger af den type, der er vist i det ovennævnte fremlæggelsesskrift, er der også en risiko for, at der dannes revner og svækkelser i den øvre flange.However, this known supporting profile is difficult to produce, especially the transverse embossings in the upper flange. Obtaining both transverse and longitudinal stiffening bumps or fractures in a profile of this type is, of course, more complicated and therefore more expensive than if the profile alone is provided with longitudinal stiffeners. When the plate 35 has transverse embossings of the type shown in the above-mentioned disclosure, there is also a risk of cracks and weaknesses forming in the upper flange.

Det er derfor formålet med den nærværende opfindelse at tilvejebringe en profil, der kan fremstilles lettere og således med lavere omkostninger, sammenlignet med tidligere kendte profi-5 ler af tilsvarende type, og den frembragte profil skal have større styrke og mindre tendens til buckling, navnlig når den udsættes for belastning ovenfra, såsom snebelastning, eller belastninger som forårsages af, at profilen tjener som trædeflade under oplægning af tagdækningen, hvorhos profilens ud-10 formning skal tjene til at nedsætte tendensen til dannelse af revner og svækkelser under fremstillingsprocessen.It is therefore the object of the present invention to provide a profile which can be more readily manufactured and thus at a lower cost, as compared to previously known profiles of similar type, and the profile produced should have greater strength and less tendency to buckling, especially when subjected to overhead loading, such as snow loading, or loads caused by the profile serving as a tread during laying of the roof covering, the shape of which profile should serve to reduce the tendency to crack and weaken during the manufacturing process.

Dette formål opnås ved en bærende profil af den indledningsvist angivne art, hvilken bærende profil ifølge opfindelsen er 15 kendetegnet ved, at den midterste del af den øvre flange i hele dens længde har en hvælvet bueform, som buer opad i forhold til kropsflangerne og i hovedsagen beskriver en cirkelbue.This object is achieved by a supporting profile of the type mentioned initially, the supporting profile according to the invention being characterized in that the middle part of the upper flange has a curved arc throughout its length, which curves upwards relative to the body flanges and generally describes a circular arc.

Foretrukne udførelsesformer for opfindelsen angives i de ef-20 terfølgende underkrav.Preferred embodiments of the invention are set forth in the following subclaims.

Opfindelsen og dens mange fordele vil blive beskrevet nærmere nedenfor under henvisning til den ledsagende tegning, hvor: 25 fig. 1 viser en bærende profil ifølge opfindelsen, set i perspektiv, fig. 2 viser et tværsnit af profilen i fig. 1, og 30 fig. 3 og 4 viser alternative udformninger af profilen.The invention and its many advantages will be described in more detail below with reference to the accompanying drawings, in which: 1 is a perspective view of a supporting profile according to the invention; FIG. 2 shows a cross section of the profile of FIG. 1, and FIG. 3 and 4 show alternative designs of the profile.

Fig. 1 viser en udførelsesform af en bærende bjælke eller bærende profil 1 ifølge opfindelsen. Profilen 1, som har en tykkelse på for eksempel 0,7-1,5 mm og er fremstillet af metal-35 plade, omfatter en hvælvet øvre flange 2 og to skrånende kropsflanger 3. Hver kropsflange 3 har forneden en udadbøjet flange 4 med en vulst 5. Når det er nødvendigt, kan der udfor-FIG. 1 shows an embodiment of a supporting beam or supporting profile 1 according to the invention. The profile 1, which has a thickness of, for example, 0.7-1.5 mm and is made of metal plate, comprises a vaulted upper flange 2 and two sloping body flanges 3. Each body flange 3 has a downwardly flanged flange 4 with a bead 5. When necessary,

DK 159563 BDK 159563 B

3 mes mere end én sådan vulst i hver af flangerne 4. Den ydre kant af mindst én flange 4 er bøjet opad til dannelse af en kantafstivning 6. Ved opbygning af en tagkonstruktion anbringes flere profiler 1 på hoveddragerne (ikke vist), idet flan-5 gerne 4 på hver af profilerne 1 bringes i indgreb med hinanden på kendt måde. Det indses, at et sikkert indgreb fremmes ved hjælp af vulsterne 5 og kantafstivningerne 6.3, there is more than one such bead in each of the flanges 4. The outer edge of at least one flange 4 is bent upwardly to form an edge stiffener 6. When building a roof structure, several profiles 1 are applied to the main supports (not shown), 5 like 4 on each of the profiles 1 are engaged with each other in known manner. It will be appreciated that a secure engagement is facilitated by the beads 5 and the edge supports 6.

Selv om kropsflangerne 3 kan være fuldstændig uden afstivnin-10 ger, er hver af kropsflangerne 3 i den viste udførelsesform forsynet med to afstivninger i form af langsgående knæk 7. Antallet af knæk 7 er imidlertid ikke afgørende for opfindelsen. Overgangen mellem den hvælvede del 2 af den øvre flange og hver af kropsflangerne 3 omfatter dels en afstivningsås 8, der 15 giver profilen 1 tilstrækkelig stivhed og styrke, navnlig når flangen 2 udsættes for belastning ovenfra, og dels et langsgående knæk 9, som også afstiver profilen 1. Fortrinsvis ligger det hvælvede partis højeste punkt i niveau med eller højere end de højeste punkter på afstivningsåsene.Although the body flanges 3 may be complete without stiffeners, each of the body flanges 3 in the illustrated embodiment is provided with two stiffeners in the form of longitudinal cracks 7. However, the number of cracks 7 is not essential to the invention. The transition between the vaulted portion 2 of the upper flange and each of the body flanges 3 comprises, in part, a stiffening sauce 8 which gives the profile 1 sufficient stiffness and strength, in particular when the flange 2 is subjected to a load from above, and partly a longitudinal crack 9, which also stiffens The profile 1. Preferably the highest point of the vaulted portion is at or above the highest points of the stiffening sauces.

Udformningen af profilen (se fig. 2) kan naturligvis også defineres sådan, at profilen udgøres af to nedre flanger 4, de dermed forbundne kropsflanger 3 og en øvre flange, der strækker sig mellem kropsflangernes 3 øverste kanter og omfatter 25 åsdannende flangedele 11, nedadbøjede flangedele 12 og en hvælvet flangedel 2, så renderne mellem flangedelene 12 og den hvælvede flangedel 2 udgør et langsgående afstivende knæk 9.The profile of the profile (see Fig. 2) can of course also be defined such that the profile consists of two lower flanges 4, the associated body flanges 3 and an upper flange extending between the upper edges of the body flanges 3 and comprising 25 ridge-forming flange parts 11, downwardly bent. flange portions 12 and a vaulted flange portion 2 so that the grooves between flange portions 12 and the vaulted flange portion 2 constitute a longitudinal stiffening crack 9.

Det indses, at den på tegningen viste, hvælvede form for den 30 øvre flange 2 i praksis kan udgøres af en udadbuende del af en cirkelbue, som nærmer sig en ellipsebue eller en parabelbue, eller kan bestå af en række af retlinede afsnit, der tilsammen udgør nævnte hvælvede bueform.It will be appreciated that the vaulted shape of the upper flange 2 shown in the drawing may in practice be constituted by an outwardly extending portion of a circular arc approaching an ellipse or parabola, or may comprise a series of rectangular sections joining together. constitutes said arched arch shape.

35 Ifølge den beskrevne udførelsesform udgøres afstivninger af kropsflangerne 3 af knæk 7, der strækker sig i profilens 1 længderetning, men disse afstivninger kan naturligvis også ud-According to the described embodiment, stiffeners of the body flanges 3 are made of knuckles 7 extending in the longitudinal direction of the profile 1, but these stiffeners can of course also be provided.

DK 159563 BDK 159563 B

4 formes som vulster (ikke vist). Afstivningerne kan også omfatte andre typer af indskæringer, prægninger eller lignende deformer inger.4 is formed as beads (not shown). The stiffeners may also include other types of notches, embossings or similar deformations.

5 I fig. 2 ses det, at bredden af den øvre flange 2 er betydeligt større end bredden af hver af de nedre flanger 4, idet forholdet mellem bredderne ifølge den viste udførelsesform er omkring 7,5:1.5 In FIG. 2, it is seen that the width of the upper flange 2 is considerably greater than the width of each of the lower flanges 4, the ratio of the widths of the embodiment shown being about 7.5: 1.

10 En fagmand på området vil også forstå, at profilen ifølge opfindelsen kan modificeres på en sådan måde, at den omfatter to eller flere med hinanden forbundne profiler af den ovenfor beskrevne type. Fig. 3 og 4 viser modifikationer med to og tre med hinanden forbundne profiler, la og lb henholdsvis.A person skilled in the art will also appreciate that the profile of the invention can be modified in such a way that it comprises two or more interconnected profiles of the type described above. FIG. 3 and 4 show modifications with two and three interconnected profiles, 1a and 1b, respectively.
