EP2976477B1 - Method for producing a longitudinal frame section for a roofing element - Google Patents

Description

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

Canopies with a hall character are known from the prior art. Such canopies can usually be moved by rails mounted on the floor and have various forms of openings on the side end pieces, up to doors. Such swimming pool covers or swimming pool roofs are made, for example AT 008 466 U2 and DE 195 14 230 C2 known and comprise a frame and a shield, wherein the roofing element is designed as a curved roofing element by means of longitudinal frame sections arranged on at least two opposite longitudinal edges of the shielding and wherein the curved roofing element can be placed on a substrate with two opposite transverse edges.

The canopies known from the prior art have the disadvantage that they are complex to manufacture and their span is limited to approximately 5 to 6 meters.

Furthermore, from the FR 2 873 395 A1 a swimming pool roof for low shelters is known, which consists of roof elements arranged next to one another in the longitudinal direction of the swimming pool.

From the DE 22 33 440 A1 a hall construction is known, the hall being guided in slot-shaped walls Floor pockets is carried hanging freely by a lifting device acting on the hall roof.

From the U.S. 2004/099383 A1 discloses a covering structure for swimming pools, suitable for at least partial opening, consisting of several parallel pairs of brackets and deformable plates, the brackets being formed by a curved profile, the side walls of which have a series of parallel, superimposed guide grooves perpendicular to the surface of the bracket.

Finally is out of the CH 277 562 A a coach house with two opposite side walls is known, the roof, which consists of a fixed part and a part serving as a door, is arcuate, the connection of each side wall to the fixed part of the roof being formed by a respective profile rail, which is a has the relevant edge of the side wall and a U-profile receiving the relevant edge of the fixed roof part, and the roof is curved according to an arc of a circle.

The object of the invention is to propose a method for producing a longitudinal frame section for a roofing element which, with a simple structure, enables large spans and with which longitudinal frame sections for such roofing elements can be produced easily and inexpensively with minimal use of material and with which a high degree of dimensional accuracy of the roofing elements is achieved. In particular, a maximum span of at least 10 meters should also be realized.

This object is solved by the characterizing features of claim 1. In the respective dependent claims advantageous developments of the subject matter of claim 1 specified.

In the roofing element, the two longitudinal frame sections each comprise a carrier and a U-profile, with the carrier forming a first arc segment in a side view, with the U-profile forming a second arc segment in a side view, with the shielding in opposite grooves of the two U-profiles is held and each U-profile is stabilized by the associated carrier. In this way, arc segments with a very high flexural rigidity can be produced from two components that 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, which forms an arc segment in the side view, from a flat material, in particular from 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, longitudinal frame sections can be produced with minimal use of material, which have high flexural rigidity due to the flat material and which, because the first arc segment is produced without a bending process, have high dimensional accuracy and are also insensitive to deformation under load.

Non-floating enclosures for wider pools can be built using the beam and U-profile system. Spans with a length L of more than 10 meters can be realised.

The canopy consists of several elements designed as canopy elements, which can be moved or opened independently of one another. In the figure 1 a roofing element U is shown as an example in a plan view of a swimming pool S. figure 2 sets the side view to the representation of figure 1 in the direction of the arrow II. The figure 3 represents the section III-III from the figure 1 represent.

The roofing element U consists of a shielding 3 made of polycarbonate, which is held on both sides over the entire span or length L by two longitudinal frame sections LRA1 and LRA2, which form a supporting system each consisting of a beam 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 in the U-profile 2 and is fixed with stainless steel screws 5.

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

The connection of the U-profile 2 with the girder 1 ensures that the lateral dimensional stability of the girder 1 is given over the length L and that the full height of the girder hT is available over the full length L to absorb the bending forces that occur under load .

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

the figure 2 shows the side view of the roof designed as a roof element U in FIG The radius R of a lower arc 12, to the course of which an upper arc 11 is adapted in its course, can be adapted depending on the individual requirements of the swimming pool S to be covered. An infinitely large radius (flat shape) can be realized. The radius can vary over the length L. Structural limitations are only to be taken into account when determining the shape due to the flexibility of the shielding 3 .

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

The size in the width direction of the swimming pool S to be covered is unlimited by using several roofing elements U. In theory, an infinite number of roofing elements can be lined up. figure 4 represents a top view of the completely covered swimming pool S. This is covered by eight covering elements, which are connected to the outer side faces 13 of their supports (see figure 3 ) are opposite.

Other expedient designs are possible due to the variability of the thickness of the shielding 3. The necessary insulation values can thus be achieved specifically for the ambient temperatures to be expected at the place of use.

Furthermore, other materials can be used. The polycarbonate of the shield 3 can be replaced with other plastics, glass or cloth materials. The aluminum of the carrier 1 and the U-profile 2 can by suitable Materials such as plastics, other metals or wood can be exchanged.

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

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

The U-profile 2 is fastened to the cut-out beam 1 along the upper arch 11 with rivets 4 (see Fig figure 3 ). In this way, the carrier 1 gives the roofing element U the curved shape of the roof. The U-profile 2 stabilizes the carrier 1 along the length L, so that the carrier 1 remains dimensionally stable even with slight transverse forces. This means that the full height hT can absorb the bending forces that occur under load.

In principle, these manufacturing steps can be transferred to all conceivable materials (e.g. plastics, wood, etc.). All connection variants (e.g. screwing, welding, soldering, clipping, etc.) can also be combined depending on customer requirements.
