Definitions
- the invention relates to a T-profile made of one piece Cutting from sheet metal with a hollow bead on top, the in one of two sheet metal layers lying on top of each other formed profile web merges, the two sheet metal layers of the profile web at its lower edges in outwards opposite angled horizontal directions Skip profile flanges.
- T-profiles are widely used in particular for suspended ceilings to form a grid used.
- the horizontally angled Profile flanges of the T-profile s the contact surfaces for the Insert cassettes filling the grid.
- the object of the invention is a T-profile of the beginning mentioned genus so that without a Increasing the sheet thickness further stiffening the T-profile and thus an increase in its load-bearing capacity is achieved.
- the clinching provides a shear-resistant Connection of the two sheet layers.
- a shear stress between these two sheet layers occurs at horizontal acting bending forces. If you take into account that even if the T-profile is overloaded vertically lateral deflection of the profile web or the entire T-profile occurs, it is understandable that a Stiffening of the T-profile compared to horizontal Bending stresses through a shear-resistant connection of the the sheet capacity of the T-profile also in vertical direction significantly improved.
- those formed by the clinching Junctions in adjacent rows against each other offset to achieve a favorable distribution.
- the T-profile 1 shown in Fig. 1 consists of a one-piece cut from sheet metal. At both ends insertion tongues 2 are formed for connection to serve the same neighboring T-profiles.
- the T-profile 1 is used, for example, as a lattice bar of a supporting grid suspended suspended ceiling used.
- An overlying hollow bead 3 goes down into one Profile web 4 over that of two superimposed Sheet metal layers 4a, 4b is formed.
- the two sheet layers 4a, 4b go in to the outside opposite angled horizontal directions Profile flanges 5 over.
- a sheet metal strip 6 At the bottom of the profile flanges 5 is a sheet metal strip 6, the two edges 6a around the outer edges of the profile flanges 5 are folded.
- FIG. 3 and 4 is another embodiment of a T-profile 1 'shown that in its cross-sectional design (Fig. 4) is constructed similarly to the T-profile 1 according to the 1 and 2. It differs essentially from this in that those formed by clinching Junctions 7 and 7 'are arranged in two rows, the junctions 7 and 7 'in the two neighboring rows are offset from each other.
- T profiles 1 and 1 'shown can for example as main profiles in the supporting grid of suspended ceilings be used.
- T-profile 1 can also be act a cross section between the main profiles 1 'according to 3 and 4 is arranged and with its tongue 2 is inserted through punched-out window 8.
