Roof element used as skylight

The definition of the invention is formed by an upper light θ serving Roof component that is predominantly or entirely made of translucent Made of plastic,

The invention is located on opposite marginal edges adjoining main part on edge parts standing at an angle, by means of v / elcher it can be placed like a hood on a roof opening i3t and the main part is due to its profile design compared to the edge parts having the shape of flat strips reinforced trained. Such roof elements are preferred as roof skylights of halls and the like, excellently suited, v / o it is a question of relatively large and slightly inclined sections of the roof between the load-bearing roof parts lichtdui'chläasiß to cover.

In some cases, especially if the covered room is heated, it is advantageous to design these roof construction elements not only to be translucent but also to be heat-insulating, otherwise condensation will inevitably form on the underside of the same, which will drip or run off makes the subsequent building construction part unpleasantly noticeable and also, when it comes to metallic w j Daoh constructions, contributes to the corrosion and gradual destruction of the same.

In this case, the main part of the roof element is made from zv / ei or more plastic sheets formed, which at least arranged at a distance from one another in the majority of their area and are firmly connected to one another at least at two opposite edges. It is a thermal insulating one in this way Component created which completely or to a large extent prevents the formation of condensation water.

The shape of the plates or their joining together can be selected in the most varied of ways, for example two barrel-shaped arched plates are provided at the same distance throughout, which only at the marginal edges, at which they sit on the roof structure, are connected to each other, can instead of barrel-shaped arched panels also two gable-roof-shaped panels placed one on top of the other with the same distance throughout and on the longitudinal edges be connected to each other. But it is not a condition

4 * 6 the plates have the same shape and the same distance over the entire surface.! Rather, when the distance also change and the main surface of the roof element consists, for example, of an upper, gabled roof-shaped plate and a lower, flat plate, or the upper plate can be barrel-shaped and the lower plate is flat, so that the main part of the roof element has a triangular baw · circular segment-shaped cross section. Of course, two plates, one of which is more curved and the other less curved, can be assembled to form a roof component of this type, so that its main part has a crescent-shaped cross-section. It is also easily possible to use connecting elements at one or more points on the main panel surfaces, for example to achieve improved stiffening and ultimately the ability to walk on the roof component. Form a gable roof with two very different angles of inclination, whereby the permeability of the slightly sloping filing can be restricted either by covered or partially covered layers (absorbing blue, UV or infrared rays) or by blind-type fixtures of opaque slats, that incident light rays that are at an angle greater than

are inclined about 30 ° to the horizontal, this surface / the skylight is no longer immediately, but only after reflection can penetrate the built-in slats, such roof skylights are particularly suitable for halls, in which substances to be protected against sunlight, such as textiles, paper, chemicals and the like are processed, or where additional heat is to be prevented by "exposure to the sun" or sunlight from acts as a hindrance to work for other reasons.

According to a further concept of the invention, the roof component is composed of two panels, of which at least one is has a corrugated profile perpendicular "to the support edges and is welded to the second, similarly corrugated or flat plate at the wave bulges, which creates a special one load-bearing and also heat-insulating spaces exhibiting, translucent ftaohbaüelement can be achieved.

When it comes to rooms like e, B, warehouses that are not are heated so that the rooflights are not heat-insulating Must have property, the roof element according to the invention can also consist of a simple plastic plate, which is reinforced in the main part by a corrugated profile compared to the edge parts having the shape of flat strips. For example, the roof element has the shape of a Sheddaohee with a steeper and a less sloping flank,

i with the less inclined flank with a wholly or predominantly opaque or a light reflective Layer is provided,

Of course, such a shed roof-shaped roof component can also be composed of a wave-shaped profiled and at least one flat plate.

Below are a number of foon exemplary embodiments with reference to the drawings of roof elements according to the invention explained in more detail.

In order to be able to cover roof sections of any length with such roof construction elements, several such elements are included in the Attached lengthways aneihjfeer. For this purpose, it is advantageous to have vertical, flange-like protruding edges at the joint edges Provide components 8, which with the corresponding flange of the next element by welding or gluing with or can be connected firmly and tightly without additional screwing. To ensure watertightness, Another misshapen plastic profile piece over the butting one Flanges 8 are pulled and glued to this so that the joint is not exposed at any point.

The embodiment according to FIG. 2 shows a similar roof structure, the two plates 11 and 12 of which are not curved, but rather the shape of a flat gable roof, whereby the dao surfaces of both plates have the same inclination. The rest of the arrangement is completely analogous to that of FIG. 1.

According to FIG. 5, the outer plate 11 may, for example, have the shape of a 'Saddle roof ·! have, while the inner plate 13 is flat so that the cross section of the cavity formed a gleiohechenkellgea triangle let.

In the embodiment of Fig. 4- the outer plate 14 is barrel-shaped, while the inner plate 15 is flat trained 1st. The cross section of this roof component therefore has the shape of a segment of a circle. To increase strength, can for example be a vertical connecting web 16, which is connected to both plates by welding, gluing or the like.

In the embodiment according to Figl 5, the roof element has two barrel-shaped arched plates 17 and 17 ¹ , which have different radii of curvature and are connected to each other at the edges of their hands, so that a crescent-shaped cross-section of the cavity formed results.

The bulge of the two plates is only in the middle part maintained, while at the two edge parts 33 and 33 'the two plates by deformation under heat and Printing in the form of planar, adjoining and welded together Plates are brought, it is clear that such a deformation only when using thermoplastic material is possible. These edge parts 33 and 33 'lie on the roof structure 34 and thus form the watertight seal. It is clear that such, multi-arched or curved Skylights are extremely strong and therefore easy to walk on. It doesn't have to be both plates be profiled in a wavy manner, but the in 9 and 10 profiles shown in cross section are used in which only the outer or the inner plate 30 or 31 is profiled in a wave-like manner and the other plate 34 or 34 · * is flat, with the latter in the roof element only has a simple, barrel-shaped curvature.
