Den foreliggende opfindelse angår et ved valsning formet byggeprofil af tyndplade med en krop og to flanger og flangeafstivninger i form af indefter ombukkede, afstivende flangekanter, idet byggeprofilet i det væsentlige har C-5 formet tværsnit og kroppen har afstivende, oppressede riller med ringe dybde.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll-shaped, thin-plate construction profile having a body and two flanges and flange braces in the form of internally bent, stiffened flange edges, the building profile having substantially C-5 shaped cross-sections and the body having stiffened, pressed grooves of low depth.

Sådanne pladeprofiler anvendes i stigende omfang i stedet for trælægter i skeletvægge, som beklædes med gips-plader. Den mest almindelige anvendelse er til ikke-bærende 10 skillevægge. Kroppen på profilet har da sædvanligvis en højde på 70 mm, og flangerne har en bredde på 35 mm, idet disse dimensioner svarer til størrelsen af de trælægter, der tidligere er blevet anvendt til det samme formål.Such slab profiles are increasingly used in place of wooden slats in skeleton walls, which are coated with plasterboard. The most common use is for non-load-bearing 10 partitions. The body of the profile usually then has a height of 70 mm and the flanges have a width of 35 mm, these dimensions being equal to the size of the wooden luminaires previously used for the same purpose.

Gipspladerne eller en anden form for beklædning fast-15 gøres til flangerne ved hjælp af selvborende og -skærende skruer.The plasterboard or other type of cladding is fastened to the flanges by self drilling and cutting screws.

Det er ønskeligt, at flangerne giver så lidt efter som muligt under denne fastgørelse af pladerne. Det er også ønskeligt, at væggen er så stiv som muligt. Et profil ifølge 20 opfindelsen opfylder disse ønsker og er ejendommeligt ved det i kravene angivne.It is desirable that the flanges yield as little as possible during this fastening of the plates. It is also desirable that the wall be as rigid as possible. A profile according to the invention meets these requirements and is peculiar to the requirements of the claims.

Opfindelsen skal i det følgende beskrives næmere under henvisning til tegningen, som viser fire udførelsesformer for profilet ifølge opfindelsen.The invention will be described in more detail below with reference to the drawing, which shows four embodiments of the profile according to the invention.

2 8, og fig. 8 er en afbildning set fra enden af profilet i-følge fig. 7 som vist ved pilene 8-8 ifølge fig. 7.2, and FIG. 8 is a view from the end of the profile according to FIG. 7 as shown by arrows 8-8 of FIG. 7th

Profilet ifølge krav 1 og 2 har en krop 11 og to flanger 12,13. Flangerne er afstivet ved hjælp af deres 5 indefter bukkede kanter 14,15. Kroppen har en serpentineformet rille 16, der består af i det væsentlige rette dele 17,18, der er forbundet med hinanden ved hjælp af tilnærmelsesvis cirkulære buer 19,20. De rette dele 17,18 strækker sig over i det mindste halvdelen af kroppens højde under en 10 vinkel på ca. 45° med profilets længderetning. Disse rette dele 17,18 forløber derfor i det væsentlige vinkelret på hinanden.The profile according to claims 1 and 2 has a body 11 and two flanges 12,13. The flanges are stiffened using their 5 inwardly curved edges 14.15. The body has a serpentine-shaped groove 16, consisting of substantially straight portions 17,18, which are connected to each other by approximately circular arcs 19,20. The proper parts 17,18 extend over at least half of the height of the body at an angle of approx. 45 ° with the longitudinal profile of the profile. These proper parts 17,18 therefore extend substantially perpendicular to each other.

Profilet ifølge fig. 3 og 4 ligner profilet ifølge fig. 1 og 2, men har to serpentineformede riller 16,21 i 15 stedet for kun en. Det mønster, som serpentinerillerne danner, er symmetrisk, og serpentinerillerne skærer hinanden under tilnærmelsesvis rette vinkler.The profile according to FIG. 3 and 4 are similar to the profile of FIG. 1 and 2, but has two serpentine grooves 16.21 instead of just one. The pattern formed by the serpentine grooves is symmetrical, and the serpentine grooves intersect at approximately right angles.

Profilet ifølge fig. 5 og 6 har to langsgående riller 24.25 med plan bund langs kanterne af kroppen 11, og disse 20 riller 24,25 er forbundet med hinanden ved hjælp af en zig- zag-rille, der består af rette dele 26,27, som har samme retning som noterne 17,18 på serpentinerillen 16 ifølge fig.The profile according to FIG. 5 and 6 have two longitudinal grooves 24.25 with a flat bottom along the edges of the body 11 and these 20 grooves 24.25 are connected to each other by means of a zigzag groove consisting of straight parts 26,27 having the same direction as the grooves 17, 18 on the serpentine groove 16 of FIG.

1. Fortrinsvis har rillerne 26,27 samme dybde som rillerne 24.25 og plan bund.1. Preferably, the grooves 26.27 have the same depth as the grooves 24.25 and flat bottom.

25 Profilet ifølge fig. 7 og 8 ligner profilet ifølge fig. 5 og 6, men har to zigzag-riller 26,27 og 28,29 i stedet for en rille. Mønsteret er symmetrisk, og rillerne 26,27 og 28,29 skærer hinanden under tilnærmelsesvis rette vinkler.25 The profile according to FIG. 7 and 8 are similar to the profile of FIG. 5 and 6, but have two zigzag grooves 26.27 and 28.29 instead of one groove. The pattern is symmetrical and the grooves 26,27 and 28,29 intersect at approximately right angles.

30 I alle de viste udformninger er der en kontinuerlig, i det væsntlige zigzag-formet afstivningsrille. I udførelsesformerne ifølge fig. 5 og 7 forbinder én, henholdsvis to zigzag-formede riller 26,27 og 28,29 to langsgående riller 24,25, således at der dannes et gitterlignende mønsker.In all of the embodiments shown, there is a continuous, essentially zigzag-shaped stiffening groove. In the embodiments of FIG. 5 and 7, one, two zigzag-shaped grooves 26,27 and 28,29 respectively connect two longitudinal grooves 24,25, thus forming a grid-like groove.

35 Fortrinsvis har de langsgående riller og de zigzag-formede riller samme dybde, således at deres bunde løber over i hinanden. Dette bevirker et kraftlinieforløb svarende til kraftlinieforløbet i et gitter. Det synes at være fordelag-Preferably, the longitudinal grooves and the zigzag-shaped grooves have the same depth so that their bottoms run into each other. This causes a power line process similar to the power line process in a grid. It seems to be advantageous-

3 tigt, men ikke nødvendigt, at både de langsgående riller og zigzag-rillerne har plane bunde som vist på figurerne.3, but not necessary that both the longitudinal grooves and the zigzag grooves have flat bottoms as shown in the figures.

Ved fremstilling af profilerne ifølge de fire eksempler begynder man med at bukke flangerne 12,13, og dernæst 5 fremstilles rillerne i kroppen 11, inden bukningen af flangerne afsluttes på konventionel måde.In preparing the profiles according to the four examples, one begins to bend the flanges 12,13 and then 5 the grooves in the body 11 are made before the bending of the flanges is completed in a conventional manner.

De zigzag-formede riller i kroppen kan fremstilles ved hjælp af to synkroniserede stålruller. Alternativt kan man anvende en af stål fremstillet han-rulle og en glat hun-10 rulle med en jævn beklædning, der er eftergivelig, men ikke for blød. Til beklædning kan der anvendes neoprengummi, og tykkelsen kan hensigtsmæssigt være 4-6 gange, fortrinsvis 5-6 gange dybden af rillerne, som skal valses ind i stålkroppen.The zigzag-shaped grooves in the body can be made using two synchronized steel rollers. Alternatively, one can use a steel-made male roller and a smooth female roller with a smooth covering that is resilient but not too soft. For cladding, neoprene rubber may be used, and the thickness may conveniently be 4-6 times, preferably 5-6 times the depth of the grooves to be rolled into the steel body.
