Edge protection j (for cladding panels

The innovation "concerns an edge protection for cladding panels and the like. Made of wood with a front profile rail and two inner expanding legs extending from these rails.

It is "already known an edge protection rail formed from bent sheet metal, which is formed on the part facing the end face of the plate to form a central leg which is spread outwards and outwards approximately from the center of the plate and again inwards at the lower end In the last piece it is inclined downwards and slightly outwards. The middle _{limb is hollow, ie the wood y,} which this middle limb would contain in its interior, has been removed. Such an arrangement has the disadvantage that the

Middle leg for strength and resilience of the profile rail at the edges where the stress on the plates and rails is greatest, not at all or only insignificantly

$ contributes. Compared to hitting, impact forces and the like

"Profile rails are exercised in the vicinity of the corners, '" ■ such a profile rail behaves similarly to when there is no expansion

legs would be provided because a deformation of the rail there is insufficient strength at the outer edges even if the profile sheet is bent.

Furthermore, it is generally known to have inwardly inclined expansion legs to be provided for edge protection profiles for formwork panels. In such known embodiments, the inner part with the expansion legs welded to the outer U-profile; the spreader legs, inclined at an angle, are straight et and run from the corners, so that the edges of the plate are at risk and the profile easily out of the plate can be torn out.

According to the innovation, there is an edge protection for cladding panels proposed in which the expansion legs at a small distance from the corners of the profile rail starting inwards and from run away from the splint, at the ^ Qie splint and the splay legs in l'Jeise, which is known per se, from a continuous Rolled strip exist, in which the expansion legs at the end facing away from the profile rail parallel to the profile rail have outwardly directed legs and in which the connection between the profile rail and expansion leg as reinforcement the corners of the rail is formed.

The renewal proposal contemporary decisive j knowledge is von.der assumed that protection in form panels with marginal \ and rail is essential to reinforce the outer edges of the \ rail, so that a deformation of the profile

Rail during operation and thus damage to the formwork panel and becoming unusable is prevented. the both inwardly protruding legs of the arrangement according to the innovation are based on the proximity of the edge of the profile rail, see above that the direction of the compressive stress on the profile rail, e.g. through impact, blow, etc., approximately in the direction of the expansion legs runs and this stress is absorbed by the expansion legs and their approaches at the free ends. Through this results in a high resistance to the Outer edges of the profiles applied shock loads and practice has shown that the innovation according to the arrangement is much more advantageous than any of the known profiles. In particular, the wood of the panel will tear open almost completely switched off.

In arrangements according to known embodiments in which the inner part with the splaying legs to the outer U-profile is welded on, the effect of the profile does not occur through the increase in resistance, but through the enlargement of the profile diameter. The extraordinarily good results that can be achieved with the arrangement according to the innovation can by far not be achieved with the known profiles, as has been clearly established in practice has been. A profile with straight expanding legs can also cope with the stresses that are exerted on the edges of the profile rail from the outside are exercised, absorb only very imperfectly, so that the

high stability and pull-out strength of edge protection rails according to the proposal according to the innovation in the known designs cannot be reached.

The subject matter is explained below on the basis of exemplary embodiments the innovation explained in connection with the drawing.

Mg. 1 shows an embodiment according to the innovation in which the edge protection carried out in a particularly advantageous manner is,

Pig. 2 shows a modified embodiment according to FIG. 1, wherein also special emphasis is placed on the edge reinforcement, and

g-s- 3 another embodiment of the edge protection rail according to the innovation .

The profile rail is on the front of the cover plate 1 2 used, which has the shape of a U-rail towards the outside. At the end of the leg 3 of the U-profile is the rail bent in opposite directions and is the course of the outer rail along the legs uad a part of the crossbar of the U-profile following down into two expanding legs that run towards one another 4 bent, which at its lower end 'a short horizontal Piece 5 and an adjoining piece 6 running approximately in the direction of the expanding legs 4. The splay legs 4 and the legs 3 are connected to one another via the intermediate piece 7. The adjacent to the legs 3 after running inside and connected to the intermediate piece 7 parts
