The present invention relates to a casing for an element

  rigid reinforcement and a corresponding construction, in particular of barrier type, obtained with such a covering envelope.

  For the construction of barrier-type construction, such as doors, gates, fences, railings, stair railings or similar structures, it is known in particular from the document FR 2 800 437 to integrate a rigid frame, which is presented generally in the form of a frame based on uprights and tubular sleepers, in a plastic cladding. Each element of the rigid reinforcement is housed in a covering envelope comprising a U-shaped cross section covering section comprising a base connecting two opposite parallel lateral branches. The trim profile is fitted on the reinforcing element and then fixed to the latter by gluing, screwing or re-grinding. A closing profile is then assembled on the covering profile to close the opening of the U. In the case of screw fixing in metal reinforcing elements, in particular stainless steel, the screws are screwed, for example to through the base, in pre-drilled holes along the element. To screw through the base in the axis of the perges, marks corresponding to the precise positions of the holes must be marked beforehand on the outer face of the base of the U. The use of oblong openings on the reinforcing elements instead of drilling facilitates or eliminates this marking and marking step, but requires additional machining of the elements. Fastening by rivet also requires the use of pre-drilled elements.

  FIG. 1 schematically represents a barrier-type construction comprising a rigid reinforcement 1, schematized in broken lines, each element of which is integrated in a covering envelope 2. The rigid reinforcement comprises a frame 10 with two uprights 11 , 12 connected in parallel to each other by an upper cross member 13, a lower cross member 14 and an intermediate cross 15. The amounts and crosspieces consist of metal tubes, for example stainless steel, of rectangular cross section, in particular square, secured to each other. others, for example by welding.

  With reference to FIGS. 2 and 3, the covering casing 2 comprises, for each frame upright, a covering profile 3 and two closure profiles 8 and 9. The covering profile is formed in one piece 30, and comprises a base 4 connecting two parallel branches between them 5a, 5b. The profile has a cross section substantially in asymmetric H, defining between its branches, on either side of the base, a main housing 31 adapted to receive the amount 12 and a secondary housing 32 of smaller dimensions than those of the main housing.

  The branches 5a, 5b consist of a partitioned double wall, comprising an outer wall 51 and an inner wall 52 interconnected by longitudinally extending webs 53.

  The base 4 consists of a single wall 40, full whose thickness is of the order of that of the outer and inner walls of the branches. For better rigidity, the base is formed substantially to the right of a sail 53a of each branch. The inner face of the base has two longitudinal bearing ribs 41, between which fixing screws 7 are screwed into bores of the upright for the assembly of the trim profile on the upright and by which the base abuts against the amount.

  According to the invention, the base is made of a translucent plastic material, allowing sufficient light to pass through in order to identify the holes in the upright through said base when the upright is inserted in the housing 31, near or against the base. The base can of course be made of a transparent material through which the holes appear sharply. The covering profile is obtained by extrusion of two plastic materials, preferably of the same kind, for example PVC type, one translucent to make the base, and the other opaque to achieve the branches.

  The longitudinal edges, said main, 33a, 33b of the trim section, which define the opening 34 of the main housing 31 by which the profile is laterally fitted on the upright, each comprise an assembly slide 35 for assembly by snap-fastening of a closure profile, said main 8. Each slide is delimited by the end edges of the outer wall 51 and the inner wall 52. The outer wall ends with a return towards the inside 54, its edge end 55 facing the end edge 56 of the inner wall 52, the latter being provided with a longitudinal bulge 56a. The main closure profile 8 is formed of a flat piece 80 provided, near each of its longitudinal edges 81, with diverging resilient lugs 82, arranged in a V-shape, able to snap into the slides 35 to close the housing. 31, as shown in FIG. 2. The longitudinal edges 81 advantageously abut against longitudinal grooves 54a provided on the outer face of the returns 54 of the outer walls 51.

  Similarly, the longitudinal edges, said secondary, 36a, 36b of the trim section, which define the opening 37 of the secondary housing, each comprise an assembly slide 38 for the snap-fitting assembly of a closure profile. , said secondary 9, this slide being also delimited by the end edge 58 of a return 57 of the outer wall, provided with a rib 57a, and the end edge 59 of the inner wall, punished with a longitudinal bulge 59a. The secondary closure profile 9 is of the same structure as the main closure profile 8. It is formed of a flat piece 90 provided with divergent elastic tabs 92 near each of its longitudinal edges 91.

  For its mounting, the profiling section 3 = is fitted on the upright 12 through the opening 34, coming to press the face of the upright provided with holes against the support ribs 41 of the base. The amount includes Io holes distributed at regular intervals, for example between 25 and 30 cm. The operator can then locate the holes of the upright through the translucent base 4, looking through the opening 37 of the secondary housing 32, to come screw screws in the holes. Advantageously, the screws are of the self-drilling type, in order to allow the base to be pierced directly during the screwing operation, without pre-drilled holes in the base. By way of example, for bores of the order of 4 mm, screws of the order of 5 mm in diameter are used. Once the cladding profile fixed on the entire height of the upright, the secondary closure profile 9 can be snapped into the slides 38 to close the secondary housing. The main housing 31 is closed by a main closure profile 8.

  In the illustrated embodiment, legs legs are formed of square section tubes, for example 30x30mm section. The spacing between the two inner walls 52 substantially corresponds to the transverse dimension of the upright. The depth of the housing, defined by the distance between the base and the main longitudinal edges 33a, 33b is in turn greater than the size of the upright, for example, more than two times greater, so as to allow the fitting of tubes of rectangle section: Larger area and / or to maintain a free space between the inserted tube and the main longitudinal edges, for the end reception of filling rails and / or electrical connections for example.

  For the assembly of vertical or oblique filling rails 17, the casing comprises, with reference to FIG. 4, a main closure profile 108 comprising a longitudinal central recess 183 into which the ends of 16. When the elastic tabs 182 are snapped into the slides 35, the central recess is engulfed in the main housing 31, bearing against the inner walls 52 of the branches 5a, 5b. The edges of the recess are provided with longitudinal ribs 184 between which the rails are clamped.

  The single-wall nature of the base 4 ensures a correct visualization of the holes of the tube through the wall. The secondary closure profile 9 serves to stiffen the connection between the two lateral branches 5a, 5b, and forms with the single-walled base, cecalized with respect to the secondary longitudinal edges a double wall system. This offset of the base, conferring this asymmetrical form of H in cross-section to the covering profile, also makes it possible to form the secondary housing 32 which can be used to house, for example, a system for articulating the upright on a fixed support, elements of locks and / or the end of smoothing pad. The casing 2 described with reference to Figures 3 and 4 is also used to wrap the cross 13-15 of the barrier. In the case of the intermediate crosspiece 15, the secondary housing 32 can receive the end of the vertical rails 16 via a closure profile 109, as described above with reference to Figure 4.

  The inner wall 152 of the wing 1C33 of the second piece 130b has a longitudinal assembly groove 160 comprising a shoulder 161, said shoulder defining an inlet section and a bottom section. The opposite edges of the bottom section of the groove are provided with longitudinal ribs 162 arranged substantially in the extension of the shoulder. A longitudinal web 150b is advantageously provided between the bottom 163 of the groove and the outer wall to stiffen the groove. A longitudinal web 153a is also provided between the inner and outer walls of the wing 1031 to the right of the fin 1032.

  The free longitudinal edge of fin 1032 has a longitudinal tongue 142, arranged perpendicular to the plane of the fin, and handles on its outer face two divergent elastic tabs 143 arranged in V. The assembly of the two profiled pieces is carried out by engagement of the elastic tabs 143 in the groove 160, the tabs coming elastically engaging behind the ribs 162, the tongue 142 bearing on its outer face against the shoulder 161, the longitudinal edges of the tongue being wedged between the longitudinal edges of the entrance section. The height of the inlet section substantially corresponds to the thickness of the tongue, so that the inner face of the latter is: _ement at the same level as the outer face of the outer wall 151 of the wing 1033. The positioning of the fin and the groove are defined so as to form, after assembly of the two profiled parts, a casing section 103 of substantially H-shaped asymmetric cross section, with a main housing 131 and a secondary housing 132 from and star of the base 104.
