 There is shown in Figure 1 schematically from the side, the roof 1 of a veranda leaning against the wall 2 of a house. For the construction of said veranda, a masonry fixing profile 3 which is fixed to the load-bearing wall 2 by means of traditional screws, not shown. A sand pit 4 is arranged at the end opposite to the masonry profile 3 and is held by retaining beams 5; the beam assembly 5, sandpit 4, masonry profile 3 forms the frame of the veranda.

 Conventionally, rafters 6 are arranged at regular intervals between the masonry profile 3 and the plate 4, as shown in FIG. 1.

 These rafters 6 consist of an aluminum profile provided with a core 7 arranged vertically and extended horizontally in its lower part by at least one wing 8 for the rafters of banks (framed part B of FIG. 2) and two wings 8 symmetrical with respect to the core 7 of the rafter 6 for the other rafters (boxed part A in FIG. 2). Each of the wings 8 being intended to support the edge of a panel 9, as illustrated in FIG. 2.

 Thus, once these rafters 6 are arranged, it is possible to cover the frame with translucent panels 9 of the glazing or insulating plate type.

 These panels 9 are placed on the wings 8 of the rafters 6 which are further provided with a resilient material 10 of the rubber seal type pressed into grooves provided on the wings.

 A cover 12 having in cross section substantially the shape of an inverted U, the free ends of the branches of the U each having a groove 13 for insertion after immobilization of the cover 12 on the rafter 6 of a resilient material 14, so that this material presses against the top of the panel so as to seal the roof covering.

 According to the present invention, this cover 12 comprises means allowing its engagement by longitudinal sliding on each rafter 6 and means for locking its sliding on the rafter 6 accessible from the interior of the roof 1.

 Furthermore, the core 7 of each rafter 6 comprises means for fixing a plurality of reinforcements in order to adapt the number of reinforcements to the resistance.

 desired rafters which is determined depending in particular on the weight of the panels, the length of the rafter, the spacing of the rafters and conventional pressures.

 To do this, the core 7 of the chevron 6 consists of two side walls 15 and 16, a bottom 17 and a top 18 delimiting between them a cavity 19. Each of the side walls 15 and 16 comprises symmetrically with respect to its longitudinal axis a pair of claws 20,21 projecting outwards intended to block a reinforcement 22. Similarly, inside the cavity 19, on the wall of the bottom 17 and of the top 18, is produced a groove 23 in order to allow a modular accommodation of a plurality of reinforcements 22. Each of the reinforcements 22 advantageously consists of a galvanized sheet.

 FIGS. 6 to 8 show different arrangements of reinforcements 22 on the core 7 of each rafter 6 in order to illustrate the filling modularity offered by such a rafter structure 6 according to the invention. It will be noted that the number of reinforcements 22 for a chevron can range according to the embodiment shown up to five, namely two reinforcements on the outside and three reinforcements inside the cavity 19 of the core 7. A such a reinforcement housing arrangement thus offers twelve levels of inertia depending on the number of combinations of reinforcements.

 There is shown in Figures 2 to 5, a particular embodiment of the panel fastening device 9. According to this embodiment, the sliding means of the cover 12 on the rafter 6 consist of conjugate projecting parts 24.25 having in cross section the shape of an L able to cooperate in order to form a slide whose protruding parts of the cover 12 and the rafter 6 respectively constitute the slide and the rail.

 As can be seen in the figures, these projecting portions 24.25 are arranged respectively on the inner face of the branches of the cover 12 and on the outer face of the side walls 15.16 of the core of the rafter 6.

 It will be noted that the edge rafters, as visible in FIG. 5, further comprise on the branch of the cover 12 located near the edge of the roof, a second projecting part 26 intended to cooperate with a second projecting part 27 of the core 7 together forming a reinforcement making it possible to prevent any deformation of this branch of the cover 12 by a person wishing to remove this cover in order to lift a roof panel.

 Furthermore, this cover 12 also comprises means for locking its sliding accessible only from the inside of the veranda. These means consist, according to one embodiment, of at least one wedge 28 disposed in the bottom of the cover 12 fixed to the latter by screws or by other equivalent means, not shown. Each of these shims 28 disposed substantially at regular distance along the length of the cover 12, as visible in FIG. 1, is intended to form a stop against the end of a screw 29 engaged on the side of the wings 8 and passing through the core 7 of chevron 6.

 According to an alternative embodiment, each of the wedges 28 is intended to be crossed by a screw, not shown, engaged on the side of the wings 8 of the rafter 6, that is to say from the inside of the veranda, and also passing through the soul 7 of the chevron 6.

 The operation of the panel fixing device according to the invention, applied to the fixing of veranda roof panels 9, which already emerges from the description which has been given above, will now be explained in more detail.

 The operator arranges on the frame, not described in detail in the remainder of the description, the rafters 6 at regular distance, in particular fixing the latter on the masonry profile 3.

 Once the rafters 6 in place, the operator has the panels 9 on the wings 8 of the rafters 6 which are further provided with a rubber seal 10 pressed into grooves 11 arranged on the wings 8 then slides a cover 12 from the bottom of the slope upwards on each rafter 6, as illustrated in FIG. 3. A seal 14 is then pressed into the grooves 13 of the branches of the cover 12 thus ensuring the waterproofing of the roof 1. Finally, screws, by example 29, are engaged from the inside of the veranda in order to lock the sliding of the cover 12 on the rafter 6.

 It is found that this device makes it possible, in a simple manner, to provide security for dismantling from the outside of a roof panel 9 while retaining ease of assembly for the operator.

 FIGS. 6 to 8 show alternative embodiments of the sliding means which are described below.

 We can see in Figure 6, the chevron 6 which is provided with a ring 30

These protruding parts 24 ′ arranged along the length of the cover 12 consist of a longitudinal tongue capable of engaging in a groove 25 ′ formed in the ring 30. In order to ensure safety for the device, that is to say to avoid removing the cover 12 from the rafter 6, each of the tabs 24 ′ from the cover 12 is inclined relative to the core 7 of the rafter 6 at an angle between 30 and 60 degrees.

FIG. 7 shows an alternative embodiment of the device according to which the ring 30 of FIG. 6 is integrated into the core 7 of the rafter 6.

Furthermore, the sliding means described above can be reversed, namely that the cover 12 can comprise, over its entire length and symmetrically on each branch of the cover 12, a pair of tongues 31, 32 spaced apart so as to form a rail for guiding a projecting part 33 of the rafter 6 able to cooperate inside said rail, as visible in FIG. 8.

We can see in Figure 9, a last non-limiting variant in which the sliding means consist of a rail formed in the core 7 of the rafter 6 and a slide having the shape of an inverted T arranged in the bottom of the cover 12 able to cooperate with the rail in order to form the slide.

It will be understood from reading the description above that the device for fixing panels 9, in particular veranda roof panels according to the invention is relatively simple to produce and allows security against break-in relative to the prior art.

Furthermore, this device provides easy adaptation of the reinforcements 22 of rafters by allowing a modular arrangement of these, as illustrated in Figures 6 to 9. In addition, such a device allows an economic advantage through the use of reinforcements made of galvanized sheet with respect to the devices of the prior art.

Although the invention has been described in connection with a particular embodiment and variant embodiments, it includes all the technical equivalents of the means described.
