Here, two longitudinal frame sections (LRA1, LRA2) each include a carrier (1) and a U-profile (2), the carrier (1) forming a first arched segment (9) in side view and the U-profile (2) in side view forms a second arch segment (9), the shield (3) being held in opposing grooves of the two U-profiles (2) and each U-profile (2) being stabilized by the associated carrier (1).

Description

The invention relates to a roofing element according to the preamble of claim 1 and a method for producing a longitudinal frame section according to the preamble of claim 7.

Roofs in hall character are known from the prior art. Such roofs are usually displaced by ground-mounted rails and have various forms of openings on the lateral Abschlußus, up to doors. Such pool covers or pool roofs are z. B. off AT 008 466 U2 and DE 195 14 230 C2 are known and comprise a frame and a shield, wherein the roofing element is formed by at least two opposite longitudinal edges of the shield arranged longitudinal frame sections as a domed 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.

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 allows large spans with a simple structure and in which with minimal material use longitudinal frame sections for such roofing elements are simple and inexpensive to produce and in which a high dimensional accuracy of the roofing elements is reached. 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 are given.

In the roofing element according to the invention, the two longitudinal frame sections each comprise a carrier and a U-profile, wherein the carrier forms a first arc segment in side view, the U-profile forms a second arc segment in side view, wherein the shield in opposing grooves of the two U-shaped Profiles is maintained and wherein each U-profile is stabilized by the associated carrier. As a result, it is possible to produce arc segments with a very high bending stiffness from two components which are easy to produce and easy to machine, namely a carrier and a U-profile, so that large distances can be bridged with little use of material.

The method according to the invention comprises the steps of cutting out a carrier forming a curved segment in a side view from a flat material, in particular a metallic flat material, bending a U-profile rail to an arc-shaped course adapted to the carrier and connecting the U-profile rail to the carrier.

As a result, can be produced with minimal material use longitudinal frame sections which have a high bending stiffness by the flat material and which 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.

Hereby shows:

1 a plan view of a swimming pool, which is covered by a roofing element;

2 : a side view on the representation of the 1 in the direction of arrow II;

3 : a section through the representation of the 1 along a section line III-III;

4 : a top view of that from the 1 well-known swimming pool, this one through. seven other roofing elements is completely covered;

5 : a perspective distorted single view of the in the 1 shown roofing element and

6 : A top view of a circuit board with a pattern for twelve carriers.

The roof consists of several elements designed as roofing elements, which can be moved or opened independently of each other. In the 1 is exemplified a roofing element U in the plan view of a swimming pool S. 2 represents the side view on the representation of the 1 in the direction of arrow II. The 3 represents the section III-III from the 1 represents.

The roofing element U consists of a shield 3 of polycarbonate held on both sides over the entire span or length L of two longitudinal frame sections LRA1 and LRA2 comprising a supporting system consisting of one support each 1 and a U-profile 2 form (see also 3 ). The carrier 1 is to the U-profile 2 with aluminum blind rivets 4 riveted. The shield 3 lies in the U-profile 2 and is with stainless steel screws 5 fixed.

The geometry of the carrier 1 is able to absorb very high bending forces. Depending on the span of length L to be bridged, the height hT of the beam must be dimensioned (see 1 and 3 ).

The connection of the U-profile 2 with the carrier 1 Ensures that the lateral shape stability of the wearer 1 is given to the length L and thereby the full height of the carrier hT is available for receiving the resulting bending loads under load over the full length L.

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

The 2 represents the side view of the cover formed as a canopy U in the arcuate version. The radius R of a lower arc 12 , on whose course an upper arch 11 is adapted in its course, can be adjusted depending on the individual requirements of the covered swimming pool S. 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 Design constraints must be considered when determining the shape.

The size in the direction of the length L of the swimming pool S to be covered can be varied over the high span of more than 10 meters made possible in the context of the invention.

The size in the direction of a width of the swimming pool S to be covered is unlimited by the use of several canopy elements U possible. Theoretically, an infinite number of roofing elements can be strung together. 4 represents a plan view of the fully covered swimming pool S dar. This is covered by eight roofing elements, which are with outer side surfaces 13 their wearer (see 3 ) are opposite.

Further expedient embodiments are due to the variability of the strength of the shield 3 possible. The necessary insulation values can thus be achieved specifically for the expected ambient temperatures at the place of use.

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 can through suitable materials such. As plastics, other metals or wood are exchanged.

The 5 represents a perspective distorted representation of the canopy U, in order to better understand its structure, namely the course of the two longitudinal frame sections LRA1 and LRA2.

The production of the bearing system, consisting of carrier 1 and U-profile 2 is realized in the following steps (see also 6 ):
First, the carriers 1 cut out according to the necessary dimensioning of an aluminum board P on a 2D laser cutting machine. 6 shows the top view of a board P with sketched on carriers 1 for 6 roofing elements U, each consisting of two load-bearing systems.

To the cut out carriers 1 gets along the upper arch 11 the U-profile 2 with rivets 4 attached (see 3 ). This gives the carrier 1 the roofing element U the arcuate roof course. The U-profile 2 stabilizes the wearer 1 along the length L, so that even with slight lateral 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.) can be combined depending on the customer's wishes.
