Description

 The present invention relates to a frame element intended to be fixed on a support and making it possible to receive roofing elements and, in particular, for the production of roofs, facade claddings, etc.

Currently, various techniques are known for covering roofs or covering façades, possibly incorporating elements of thermal or sound insulation.
In general, the panels or covering elements used for this purpose, overlap along their edges to ensure proper sealing.

 The degree of overlap of the panels depends on their inclination, so as to prevent runoff from rising up between the panels, slates, etc. and wet the underside of the roof in the case of roofing elements, such as slates, one proceeds by a so-called "tiercée" laying so that in fact only a third of the surface of the slate is visible.

 For reasons of installation economy, etc.

it would be desirable to use cover panels having a certain dimension and not relatively small cover elements.

 Although such panels are already used for example for the coating of facades or roofs, the problem of the 3ction of these panels and their recovery at the anointing level remains posed.

 The object of the present invention is to create a structural element facilitating the use and design of roofing panels, facades, etc. allowing a simplified installation of such panels while ensuring a good tightness; tee and a good evacuation of water, without posing any problem of storage, dimensioning of the elements, etc.

To this end, the invention relates to a frame element intended to be fixed on a support and to receive cover elements, element characterized in that it is constituted by a tubular element whose body has a U-shaped section, forming a water receiving channel terminated at its base by fixing lugs, the upper branches of the body being terminated by fixing wings for the covering elements, these fixing wings possibly comprising sealing means
Such an element can be fixed on any continuous or discontinuous support, such as a wall, or a main frame, for example by being nailed using the tabs terminating the body. As these legs are preferably continuous, this gives great freedom of choice for fixing. The interior of the body which constitutes the receptacle for runoff water is not crossed by the fixing means, there is no difficulty for keep the seal. In addition, the fixing lugs can be used for fixing in the intermediate parts, of cladding panels, insulating panels etc. facing the interior of the attic.

 In the case of roofs or cladding, it is sufficient to install the elements at an appropriate interval.

These elements open into a gutter or into a channel.

After this implementation, the cover elements are fixed, previously dimensioned. In a simple case, the covering elements do not have curved edges, which simplifies their production and their cutting while reducing falls. According to another variant, the frame elements are for example arranged along the lines of greatest slope and are combined with frame elements, the like, arranged laterally between the other elements and emerging therefrom by connecting elements. The frame thus produced corresponds to a network crisscrossing the roof. This solution makes it possible to avoid any overlap since the covering elements are bordered on all four sides by structural elements capable of collecting runoff water.

 It is particularly advantageous to produce a frame element whose U-shaped section of the body is subdivided by a partition delimiting in the lower part of the U-shaped section, a safety cavity and in the upper part, a receiving and water flow. This allows at the same time to reinforce the structural element, to create a safety cavity and to respect the necessary height which the element must present to form a ventilation space.

In addition, the safety cavity allows, in the event of a leak in the partition, to recover the water and evacuate it.
In a particularly interesting way, the body has a U-shaped section, flared, starting from its base towards the upper part.

 This section shape makes it possible to reduce the overall size of the element in the plane of its section, because the fixing lugs are located at the base of the body, that is to say at the level of the part of narrower body width. This shape also reduces the width of the bottom of the channel collecting the runoff water, thus accelerating the speed of flow of the water, avoiding spillage in the case of slight slopes.

 This effect can be improved if, according to another characteristic, the partition which subdivides the body of the frame element, has a V-shaped section and its thickness is greater in the middle than at its edges.

 This section in the form of a flattened V makes it possible to group the water streams in the middle of the partition, at the point of the greatest thickness of the partition, which makes it possible to avoid the effects of wear by erosion.

 Advantageously, the sides of the body are terminated at their upper part by wings forming supports for fixing the cover elements, these wings being extended by sealing means.

 The fixing wings thus constitute at the same time sealing luvres which are supported under the covering elements, preventing water infiltration by runoff under the effect of the wind, etc.

 The structural elements according to the invention have a section allowing their realization by extrusion or spinning this allows in many cases (within the limits of possible dimensions for transport or allowing handling) to have elements in one piece, this which reduces the problems of element binding and the risk of leaks.

 According to FIG. 1, the frame element of tubular form consists of a tubular body 1, of rectangular section or, more generally, of U-shaped section, terminated at its base by fixing lugs 2, continuous or interrupted and at its upper part by fixing wings 3 which serve to receive and fix the cover panels 4 fixed, as is schematically represented, by spikes, nails 5 or other fixing means.

 The frame element 1 is itself fixed by fixing members, such as spikes 6 to a support 7, shown generally. The support 7 can be constituted by the strongly load-bearing parts of the frame such as the purlins, a facade, etc. and any support intended to receive cover panels 4 by means of structural elements, according to the invention.

 The body 1 of the frame element thus placed on the support 7, and after fixing the cover panels 4, defines an opening 8 which remains between the corresponding edges of the cover panels 4 as well as between the edges of the wings fixing 3.

 The runoff from the cover panels 4 can thus be collected inside the body 1 forming a discharge channel.

 FIG. 2 represents a second embodiment of a frame element, according to the invention. This structural element is distinguished from the element of FIG. 1 by the shape of the body 10 which is horizontally subdivided by a partition 11 defining, in its upper part, a channel 12 for collecting the runoff water and, in its lower part, an insulation and safety cavity 12.

In the event of a leak, the cavity 12 prevents the leakage runoff from reaching the support 7.

 Figure 3 shows a third embodiment of the invention.

 In this third embodiment, the body 20 of the frame element has a trapezoidal shape, in order to limit the overall size of this element due to the necessary presence of the fixing lugs 2 and allow the assembly to be inscribed. in an apparent rectangular outline.

 Figure 4 is a sectional view of a preferred embodiment of a frame member. The body 30 of the element has a U-shaped section, flared, and the fixing wings 31 constitute the folded extension of the side walls of the body 30. These wings 31 end in a curved front part 32 forming a lip which s 'presses against the underside of the cover panels 4 to seal.

The fixing is done, as before, for example using spikes or nails 5 or even using pliers.

 The flared shape of the body 30 of the frame element allows this element to be inscribed in an apparent contour of square or rectangular section, to prevent the fixing lugs 33 not protruding from this apparent contour, this facilitates manufacture, packaging. , transport, etc.

 The partition 34 separates the interior cavity from the body, as in the example in FIG. 3, into a channel 35 for the flow of water and into a safety cavity 36. This partition 34 has a V-shaped section, very flattened, and in the middle, the thickness of the partition 34 is greater than at the edges, to compensate for wear by runoff.

 In general, it is advantageous for the fixing lugs 2, 33 of the various embodiments of the frame element, to be continuous; these fixing lugs can thus serve, in the case of structural elements fixed on other load-bearing elements of the framework.

Furthermore, these tabs also make it possible to fix insulation or finishing panels 71, etc. then coming in place of what (in the left half of Figure 4), is represented by the support 7 and which only exists from interval to interval.

 The diagram in Figure 5 shows a roof made using structural elements according to the invention, these structural elements receiving the cover panels 4 which overlap in the direction of the slope, the edges of these elements 4 being aligned at the openings 8 of the structural elements. These structural elements are in fact arranged in the direction of the greatest slope, at an appropriate interval depending on the width of the panels 4.

 The arrows A indicate the course of the runoff water, which is finally collected by the gutter 100 discharging it by the downpipes 101.

 FIG. 6 shows a vertical wall 200 furnished with structural elements 201, according to the invention. These structural elements are arranged vertically at an appropriate interval to receive insulation elements 4 ′ which are covered by the panels 4.

 FIG. 7 shows a detail of FIG. 6 and in particular the arrangement of the elements 201, of the covering panels 4 which overlap vertically.

 Figure 8 is a section of a roof by a vertical plane, passing through the greatest slope. This view shows a frame element 210, directed in the direction of the greatest slope, as well as a transverse frame element 211, which leads into the previous one by a connection not shown.

 In the assembly envisaged in FIG. 8, the frame elements 211 open into some of the frame elements 210 by means of junction parts not shown, such as T-shaped branches.

 In general, the frame elements according to the invention are produced in the form of profiled parts, preferably made of synthetic material, obtained by extrusion.

These frame elements can thus be cut to the length of the frame or in the case of great length be assembled by simple fitting.

 The structural elements can also be made of metal, in particular spun aluminum.

 The elements allow a particularly simple and fast installation of the cover panels. This simplicity also has repercussions on the design of the panels themselves which have only a reduced overlap and consequently a reduced installation cost.

 In general, the above description relates to structural elements terminated by flat legs, intended to come on a support. I1 is also conceivable to produce legs which, compared to the previous ones, would for example be curved by 900, to come in the extension of the side walls of the body as in Figure 1, these legs then applying against the sides of elements carriers such as beams. This solution can be envisaged in particular when there are already load-bearing elements directed in the direction of the structural members of the tube according to the invention. In this case, it suffices to mount the structural elements, according to the invention, on such load-bearing elements.

 Conversely, this type of assembly makes it possible to simplify the manufacture of the structural elements which are no longer necessarily self-supporting since they are supported on the supporting elements located below. This allows, in particular, to reduce the height of the structural elements and to arrive at flatter elements since their only function is then to collect runoff.

 In the case of frame elements intended to come to cap load-bearing elements, it is preferable that the width of the frame element or the interval between the curved legs correspond to the width of the load-bearing element which it covers. .
