Abstract

A substantially C-formed sheet metal profile has a continuous substantially zig-zag formed groove in its web. According to one embodiment of the invention, (Fig 1), the groove (16-19) is a serpentine groove. According to an other embodiment (Fig 5) the zig-zag groove (26, 27) has straight diagonal grooves that join with two longitudinal grooves (24, 25) in a lattice-like pattern. The illustrated profiles will have an improved stiffness.

Description

Sheet metal profile
This invention relates to a i-rα-DSt-c-.Λti-ally C-formed sheet metal profile having a web with stiffening grooves and two flanges with inwardly bent edges that stiffen the flanges.
Such sheet metal profiles are increasingly used in place of wooden studs in framework walls lined with plaster board. The most common use is for partitions that do not carry a load. The web of the profile is then ususally 70 mm and the flanges are usually 35 mm; these dimensions corres¬ pond to the size of common wooden studs for the same purpose.
The plaster board or any, other possible lining is screwed to the flanges of the profile by means of self boring and tapping screws.
It is desirable that the flanges give away as little as possible during this securing of the board. It is also desir¬ able that the wall is as stiff as possible. A profile in accordance with the invention fulfilles the above require¬ ments and it has been given the characteristics defined in the claims.
The invention will be described in more detail with reference to the accompanying drawings that show four embodi¬ ments of a profile in accordance with the invention.
Fig 1 is a view of a first embodiment seen as indicated by the arrows 1-1 in Fig 2 and Fig 2 is an end view seen as indicated by the arrows 2-2 in Fig 1.
Fig 3 is a view of a second embodiment seen as indicated by the arrows 3-3 in Fig 4 and Fig 4 is an end view seen as indicated by the arrows 4-4 in Fig 3.
Fig 5 is a view of a third embodiment seen as indicated by the arrows 5-5 in Fig 6 and Fig 6 is an end view seen as indicated by the arrows 6-6 in Fig 5.
Fig 7 is a view of a fourth embodiment seen as indicat¬ ed by the arrows 7-7 in Fig 8 and Fig 8 is an end view seen as indicated by the arroew 8-8 in Fig 7.
The profile according to claim 1 and 2 has a web 11 and two flanges 12, 13. The flanges are stiffened by their in- warding bent edges 14, 15. The web 11 has a serpentine formed groove 16 that consists of substantially straight parts 17, 18 joined by substantially circular bows 19, 20. The straight parts 17, 18 extend over at least half the width of the web at an angle of about 45 to the longitudinal direction of the profile. These straight parts 17, 18 are thus substanti¬ ally at right angle to each other.
The profile according to Figs 3 and 4 are similar to the one according to Fig 1 and 2 but it has two serpentine grooves 16, 21 instead of one. The pattern formed by the serpentine grooves is symmetric and the serpentine grooves 16, 20 intersect at a substantially right angle.
The profile according to Figs 5 and 6 has two longitu¬ dinal flatbottomed grooves 24, 25 along the edges of its web 11 and these grooves 24, 25 are connected by a zig-zag groove that consists of straight grooves 26, 27 that have the same directions as the grooves 17, 18 of the serpentine groove 16 in Fig 1. Preferably the grooves 26, 27 have the same depth as the grooves 24, 25 and flat bottoms.
The profile according to Figs 7 and 8 is similar to the one shown in Figs 5 and 6 but it has two zig-zag grooves 26, 27 and 28, 29 instead of one groove. The pattern is symmetric and the grooves 26, 27 and 28, 29 intersect at substantially right angles.
In all the illustrated embodiments, there is a con¬ tinuous substantially zig-zag formed stiffening groove. In the embodiments according to Figs 5 and β , one respectively two zig-zag formed grooves (26, 27 and 28, 29) join with two longitudinal grooves 24, 25 so that a lattice-like pattern is formed. Preferably, the longitudinal grooves and the zig-zag formed grooves should have equal depth so that their bottoms are joined. This provides for a force flow akin to the flow in a like lattice. It seems advantageous though not necessary that both the longitudinal grooves and the zig-zag grooves have flat bottoms as shown in the Figures.
When manufacturing profiles according to any one of the four examples shown in a roll forming process, one starts bending the flanges 12, 13 and then makes the grooves in the web 11 before one finishes the bending of the flanges in the conventional manner. The zig-zag formed grooves in the web can be made by means of two synchronized steel rolls. Alternatively, one may use a male steel roll and a non-grooved female steel roll with an even lining that is resilient but not too soft. Neoprene rubber can be used as a lining and its thickness can suitably be 4-6 times, preferably 5-6 times, the depth of the grooves that is to be rolled into the steel web.
