Description

Roofing element and method for producing a longitudinal frame section for a roofing element

The invention relates to a roofing element according to the preamble of claim 1 and a method for

Production of a longitudinal frame section corresponding to

Preamble of claim 7.

In the prior art canopies are in

Hall character known. Such roofs are usually displaced by ground-mounted rails and have different forms of openings on the side

Final parts, right up to doors. such

Swimming pool covers or pool enclosures are e.g. from AT 008 466 U2 and DE 195 14 230 C2 and comprise a frame and a shield, wherein the

Roofing element by at least two

Longitudinal frame sections arranged opposite opposite longitudinal edges of the shield is formed as a curved roofing element and wherein the curved roofing element with two opposite transverse edges can be placed on a substrate.

The roofs known from the prior art have the disadvantage that they are expensive to manufacture and are limited in the span to about 5 to 6 meters.

CONFIRMATION COPY The object of the invention is to propose a roofing element or a method for producing a longitudinal frame section for a roofing element, which in a simple

Structure large spans allows and in which with minimal use of material longitudinal frame sections for such roofing elements are simple and inexpensive to produce and in which a high dimensional stability of

Roofing elements is achieved. In particular, a maximum span of at least 10 meters should be realized.

This object is solved by the characterizing features of claim 1 and 7, respectively. In the respective subclaims advantageous developments of the subject matter of

Claim 1 specified.

In the roofing element according to the invention, the two longitudinal frame sections each comprise a support and a U-profile, wherein the support in side view a first

Arc segment forms, the U-profile forms a second arc segment in side view, wherein the shield is held in opposite grooves of the two U-profiles and wherein each U-profile is stabilized by the associated carrier. As a result, from two easy to manufacture and easy to edit components, namely a carrier and a U-profile, arc segments with a very high

Material use large distances can be bridged.

The inventive method comprises the steps of

Cutting out a in the side view of an arc-forming carrier made of a flat material, in particular of a metallic sheet, bending a U-profile rail on the carrier adapted arcuate course and connecting the U-profile rail with the carrier. As a result, longitudinal frame sections can be produced with minimal use of material, which through the

Flat material have a high flexural rigidity and which, characterized in that the first sheet segment is produced without bending process, have a high dimensional stability and are insensitive even when loaded against deformation.

Non-floating canopies for wider swimming pools can be built using the system support and U-profile. Spans in the length L over 10 meters can be realized.

Swimming pool, this through seven more

Roofing elements completely covered;

Pattern for twelve wearers.

The roof consists of several elements designed as roofing elements, which can be moved or opened independently of each other. In the figure 1 is an example of a roofing element U in the plan view of a

Swimming pool S shown. FIG. 2 shows the side view on the illustration of FIG. 1 in the direction of arrow II. FIG. 3 shows the section III-III from FIG.

The roofing element U consists of a shield 3 made of polycarbonate, on both sides over the entire

Span and length L of two longitudinal frame sections LRA1 and LRA2 is held, which form a supporting system consisting of a respective carrier 1 and a U-profile 2 (see also Figure 3). The carrier 1 is riveted to the U-profile 2 with aluminum blind rivets 4. The shield 3 is located in the U-profile 2 and is fixed with stainless steel screws 5.

The geometry of the carrier 1 is capable of very high

Absorb bending forces. Depending on the span of length L to be bridged, the height hT of the beam must be

are dimensioned (see Figures 1 and 3).

The connection of the U-profile 2 with the carrier 1 ensures that the lateral dimensional stability of the carrier 1 is given to the length L and thereby the full height of the carrier hT to Recording of the resulting bending load forces over the full length L is available.

With this solution swimming pools with a width of more than 10 meters can be covered.

FIG. 2 shows the side view of FIG

Canopy U trained canopy in the

arcuate version. The radius R of a lower

Arch 12, on the course of which an upper arch 11 is adapted in its course, can be adjusted depending on the individual requirements of the swimming pool S to be roofed. It is an infinitely large radius (planar shape) feasible. The radius can vary over the length L.

Only by the bendability of the shield 3 are

to consider design constraints when determining the shape.

The size in the direction of the length L of the covered

Swimming pool S can over the within the scope of the invention

allowed high span of over 10 meters to be varied.

The size in the direction of a width of the covered

Swimming pool S is characterized by the use of several

Roofing elements U unlimited possible. Theoretically, an infinite number of roofing elements can be strung together. Figure 4 shows a plan view of the fully covered swimming pool S dar. This is from eight

Roofing elements covered, which overlap with outer

Side surfaces 13 of their carrier (see Figure 3) are opposite.

Further expedient embodiments are possible by the variability of the thickness of the shield 3. The necessary Insulation values can thus be specific to the expected

Ambient temperatures can be achieved on site.

Furthermore, other materials can be used. The polycarbonate of the shield 3 can be replaced by other plastics, glass or cloth materials. The aluminum of the carrier 1 and the U-profile 2 may be formed by suitable materials, e.g. Plastics, other metals or wood are exchanged.

FIG. 5 shows a perspective distorted representation of the roofing element U in order to better understand its construction, namely the course of the two longitudinal frame sections LRA1 and LRA2.

The production of the supporting system consisting of support 1 and U-profile 2 is realized in the following steps (see also FIG. 6):

First, the carrier 1 are cut out according to the necessary dimensions of an aluminum board P on a 2 D Laserschneidanla e. FIG. 6 shows the

for 6 roofing elements U, which consist of two supported systems.

The U-profile 2 with rivets 4 is fastened to the cut-out supports 1 along the upper arch 11 (see FIG. 3). Thus, the carrier 1 is the roofing element U the arcuate roof course. The U-profile 2 stabilizes the carrier 1 along the length L, so that even in light

Transverse forces of the carrier 1 remains dimensionally stable. Thus, the full height hT can absorb the bending forces occurring under load. In principle, these manufacturing steps can be transferred to all conceivable materials (eg plastics, wood, etc.). Likewise, all connection variants (eg screws, welding, soldering, clips, etc.) depend on the

Customer wishes can be combined.
