Definitions

  • the present invention relates to a covering structure for making, for example, a vault, generally transparent or translucent, intended to cover a defined area.
  • the structure according to the invention allows in particular, but not exclusively, portions of transparent or translucent surfaces in the roof of a building, the covering of corridors, passageways, shelters, awnings, etc.
  • Structures of this type generally consist of a plurality of transparent or translucent plates, for example of plastic, fixed by pinching between arches and possibly crosspieces, which define its frame.
  • Such structures must meet criteria of tightness, aesthetics, ease of assembly and occasionally ease of modification of the structure, for example by adding other surface levels while using the structure already laid. Furthermore, they generally use materials of different natures, which in particular have different coefficients of expansion. It is therefore necessary to take into account the differences in expansion in the materials assembled together, in the construction of the structure.
  • the profiles and plates are assembled by fixing the profiles together, for example by means of rivets, screws, or bolts which are distributed over the entire length of the profile.
  • the plates are engaged between the profiles and fixed by pinching, as well as the seal, when the fastening means are tightened.
  • One of the aims of the present invention is to provide a structure which overcomes the above drawbacks, which satisfies the criteria of tightness, aesthetics, ease of assembly and flexibility of adaptation of additional walls to an already laid structure. , and which also allows the plates to expand freely relative to the frame, without creating thermal bridges between the arches.
  • Another object of the invention is to propose a structure in which the assembly of the profiles constituting the arches and of the profiles constituting the connecting sleepers, when the latter are present, is homogeneous and the junction between the sleepers and the arches prevents possible water infiltration inside the structure.
  • this covering structure intended to produce for example a vault, possibly transparent or translucent, intended to cover an area situated between two substantially parallel supports in a longitudinal direction, composed of a plurality of juxtaposed covering plates located at one or several levels, and arches arranged transversely between the two longitudinal supports, each of these arches consisting of a pair of elementary arches comprising an inferior arcea laughing and an upper arch superimposed on the lower arch, the transverse edges of the plates being engaged between the lower and upper arches of each pair, means for causing the deformation of one of the superimposed arches by applying it under pressure against the 'other and thus achieve the clamping of the plates between the superimposed elementary arches, the superimposed arches having guide means extending across the level defined by the juxtaposed cover plates and comprising, on at least one of the arches, a rib and, on the other arch, a groove in which the rib of the first arch is engaged, is characterized in that the rib is engaged in the groove without being in contact with the latter so as to avoid thus formation, at this
  • Figure 1 a structure 1 made in the form of a vault which covers an area defined by two longitudinal supports 2, generally parallel, connected or not at their ends by transverse supports 3. All of these supports define , for example, a curb, which projects relative to the surface of a roof and which delimits an opening in this roof that covers this structure 1.
  • the upper surface 4 of the supports 2 is substantially horizontal.
  • the structure 1 also comprises longitudinal edge profiles 11 and 19 integral with the supports 2. It also comprises arches oriented transversely with respect to the longitudinal direction defined by the supports 2 and spaced apart longitudinally. Each of these arches is in fact made up of two elementary arches superimposed, namely an upper arch 5 and a lower arch 6.
  • cover plates 7 are for example made of a plastic material or a resin and they have a flexibility allowing their bending during assembly.
  • Structure 1 has one or more surface levels.
  • an intermediate hoop is interposed between an upper hoop 5 and a lower hoop 6 of the same pair, all these hoops 5, 6, 8 being superimposed.
  • an intermediate hoop 8 will be considered as an upper hoop with respect to a lower hoop 6 and as a lower hoop with respect to an upper hoop 5.
  • the transverse edges of the cover plates 7 are pinched between the upper 5 and lower 6 arches and the pinching is carried out by the deformation of one of the elementary superimposed arches and the pressure exerted by this deformed arch on the other.
  • This pinching is carried out without the member for fixing the arches distributed over their length, or a seal between the plates and the arches.
  • This pinching is however carried out in a completely sealed manner vis-à-vis the interior of the structure, while allowing the free expansion of the plates.
  • Figures 2 and 3 schematically show two modes of deformation of one of the elementary arches allowing such a pinching of the plates.
  • the ends 9 and 10 of the lower elementary arch 6 are respectively immobilized in position relative to the wing of the longitudinal edge profile 11 secured to each support 2, this wing being oriented substantially perpendicular to the defined curve by the arch 6.
  • This immobilization can be a stop or it can be ensured by a clamping screw.
  • it is the upper arch 5 which is deformed and this deformation consists in exerting traction on the ends 12 and 13 of the upper arch 5, this traction being substantially parallel to the tangent at the low point of the curve. that it defines.
  • Such traction is shown diagrammatically by the arrows 14 and 15.
  • the ends 17 and 18 of the upper arch 5 which are respectively immobilized in position, for example relative to the wing of a longitudinal edge profile 19 integral with each of the supports 2.
  • This immobilization can be an abutment or it can be ensured by a clamping screw.
  • the deformation mode consists in exerting a push on the ends 20 and 21 of the lower arch 6, this push being shown diagrammatically by the arrows 22.
  • This push is oriented parallel to the tangent at the low point of the curve that defines the lower arch 6. It causes, over the entire length of the lower arch 6, a pressure oriented perpendicularly at each point of the curve defined by the lower arch 6, this pressure being shown schematically by the arrows 23.
  • the lower arch 6 is thus applied under pressure, over its entire length, against the upper arch 5 and the edges of the plates are interposed and pinched between the arches 5 and 6.
  • FIGS. 4 and 5 relate to an embodiment corresponding to the deformation mode shown diagrammatically in FIG. 2.
  • the end 9 of the lower arch 6 is in abutment against a wing 25 of the profile 11.
  • a clamping screw 26 is provided to exert traction on the end 12 of the upper arch 5.
  • This screw 26 is oriented parallel to the tangent at the low point of the curve of the arch 5. Its head rests on a wing 27 of the profile 11, this wing being oriented perpendicular to the axis of the screw and offset towards the outside with respect to the wing 25 for a reason which will be specified later.
  • the threaded part of the screw 26 is screwed into one or more threaded housings of the end 12 of the upper arch 5.
  • profiles 29 are inserted between the different upper arches 5, these profiles 29 ensuring a sealed connection between the upper faces of the cover plates 7 and a wing 28 of the longitudinal edge profile 11.
  • This profile 29 has any suitable shape, for example that shown in FIG. 4 which advantageously allows it to fit into the end part of the wing 28 of the longitudinal edge profile 11.
  • the upper part 28 of the profile 11 closes and exerts pressure on the upper face of the upper arch 5, the profile 29 being made integral with the profile 11 by its fitting onto the wing 28.
  • the profile 29 follows the movement of the wing 28 and exerts a pressure on the upper face of the cover plate 7 which itself, by this pressure, is applied to the lower wing and parallel to the wing 28 of the profile 11 and thus forms a tight assembly in the longitudinal direction .
  • FIG. 5 represents a variant of the mode execution shown in Figure 4, variant in which the structure 1 has two levels of cover plates.
  • the traction members 30 and 31, such as screws, are respectively engaged in the ends of the upper hoop 5 and of the intermediate hoop 8.
  • the screw 31 engaged in the intermediate hoop 8 is tightened before the screw 30 engaged in the upper hoop 5, so as to first deform the intermediate hoop 8 on the lower hoop 6, then the deformation of the upper hoop 5 on the intermediate hoop 8.
  • the edge profile 11 has substantially the same shape as that described with reference to FIG. 4, apart from the fact that its wing 27 has a greater width which constitutes a bearing surface for the heads of the screws 30 and 31.
  • a profile 32 is interposed between the ends of the various successive intermediate arches.
  • the profiles 29 and 32 seal the assembly longitudinally when tightening the screws 30 and 31, according to the same principle previously described.
  • Figures 6 and 7 relate to embodiments corresponding to the deformation mode shown schematically in Figure 3.
  • the end 34 of the lower arch 6 is subjected to a thrust produced using a screw 35 bearing on a wing of the longitudinal edge profile 19.
  • the thrust exerted by the screw 35 can optionally be effected by means of a profile 41 oriented longitudinally.
  • the end of the longitudinal profiles 11 and 19 formed by a U-shaped section, oriented towards the outside of the structure and whose lower level is located below level 4 of the support 2, has means for collecting, channeling and evacuating the condensation water from the structure and any infiltration water.
  • the profiles 11 and 19 have means for preventing the water collected by these profiles from flowing inside the structure.
  • FIG. 8 shows an alternative embodiment of a structure 60 in which the longitudinal supports 61 have either an inclined upper face 62, substantially parallel to the tangent at the low point of the curve of the arches at their ends , or a substantially horizontal face, in which case the inclination is caught up using an appropriate fixing bracket.

  • the channel or channels are delimited by the wings constituting the pinching means, the lower wall of the lower arch 5 and part of the guide means. These channels are watertight along the length of the arch. They channel the water which could possibly infiltrate between a cover plate 7 and an arch.
  • the longitudinal support profiles have suitable means for discharging this water, for example water outlet orifices.
  • these channels contribute to the tightness of the structure since they evacuate the water coming from the outside which could infiltrate between the cover plates and the arches, more particularly the upper arch.
  • FIGS. 31 and 32 show a device of the "toggle" 98 type.
  • FIG. 33 represents a structure 150 whose range requires lengths of plates making mounting of the structure expensive and difficult. It has cover plates 7 which are juxtaposed both in the longitudinal direction and in the transverse direction. The plates are joined in the transverse direction by means of arches 151, similar to those which have been described. The junction of the cover plates 7 in the longitudinal direction is carried out by means of connecting crosspieces 152. These crosspieces connect two sets of successive superimposed arcs and their number depends on the span of the structure. The connecting crosspieces also make it possible to produce an opening, such as the opening 153, by delimiting, in a longitudinal direction, the periphery of the opening and that of the opening itself, the arches 151 delimiting the opening in the transverse direction.

  • the thickness of the flanges 167 and 168 is substantially less than the thickness of the cover plates 7 arranged at their level.
  • the lower face of the lower profile 156 of the crosspieces has at least one projecting rib. By way of illustration, two ribs 169 and 170 have been shown in FIG. 35.
  • the dimensions of the profiles constituting the crosspiece are determined so as to be in relation to those of the arches of which they provide the connection, mainly in the height direction.
  • the purpose of these relationships between dimensions is to ensure continuity between the longitudinal and transverse nip areas of the edges of the cover plates.
  • connection between a cross member and superimposed arches is achieved by nesting or pinching the ends of the profiles of the cross member in the arches and between the superimposed arches.
  • the lower profile 156 has, at each end, a projecting part 171 which is constituted by the lower face and the lower part of the wings of the U.

  • This orifice is pierced in the side wall with a sealed tubular chamber 173 located in the lower part of the lower arch 6.
  • the lower edge of the orifice 172 is located at a sufficient distance above the lower face of the tubular chamber 173, in order to allow the flow inside the lower arch 6 of the water recovered by the connecting crosspieces.
  • the flanges 168 and 167 extend beyond the ends of these profiles and constitute respective projections 174 and 175.
  • the projections 174 and 175 are located substantially at the level of the cover plates 7 and they extend respectively between the upper arch 5 and the intermediate arch 8 and between the intermediate arch 8 and the lower arch 6.

  • the central open tubular rib of the lower profile 156 can optionally be tapped at the ends so as to make this profile 156 integral with a door jamb, window, etc.
  • cover plates 7 are mounted directly between the profiles constituting a crosspiece, without having to use seals, and they allow free expansion.
  • the crosspieces present means for collecting and evacuating any external infiltration water which would infiltrate between the cover plates and the profiles constituting the crosspieces.

These channels are delimited laterally by the wings of the profiles and by the ribs constituting the guide means. They are delimited in their lower part by the lower part of the profiles. It should be noted that at the lower profile, the projecting part 171 extends the channels of this profile inside the sealed tubular chamber 173. Thus the runoff water which can infiltrate into the profiles of a cross member towards the lower profile 156 is channeled and it is evacuated towards the outside through the sealed tubular chamber 173 of the lower arch 6, which is provided at each of its ends with means of evacuation towards the outside.
  • a cross is inclined transversely since it follows the curvature of the arches at the location of the connection.

  • the means for channeling the runoff water to the lower profile 156 include, for the intermediate profile 154 , orifices 177 which are drilled in the horizontal branch of the H formed by this profile and on the left side in FIG. 35. These orifices 177 allow water, which can flow towards the lower part of the lower profile 156 infiltrate between the upper level of the cover plates 7 and the upper profile 155.
  • the orifices 177 of the intermediate profile 154 located on the right side of FIG. 35, that is to say towards the lower level of the slope, are equipped with funnels 179 which define, with each orifice 177, a sealed pipe tube opening below the level of the cover plates 7 of the lower level.
  • the stops 178 seal the water evacuation channels defined by this profile. These stops are for example assembled to the horizontal part of the H, by screwing.
  • the channels of the lower profile 156 and more particularly the channel oriented towards the top of the slope channel the water towards the interior of the sealed tubular chamber 173 of the lower arch 6, through which it is discharged towards the outside. It should be noted that the channels of the lower profile 156 open into the sealed tubular chamber 173 at a level at least equal to the level that the water could reach in this chamber, so as to avoid saturation or overfilling of this chamber.
  • the lower profile 156 of the cross member laterally preferably has two gutters 181 and 182 which collect the condensation water from the structure. These gutters extend into the projecting part 171 and open into the sealed tubular chamber 173 via the opening 172. Thus, the condensation water is also collected, channeled and evacuated.
  • Figure 37 shows schematically the connection between an opening, such as the opening 153 shown in Figure 33, and a cross which defines the opening in a longitudinal direction.

  • the cross-member 183 has the same means of interlocking in the arches and pinching between the arches as that which was previously described.
  • the connection between the cross member and the end of the opening is made substantially leaktight by means of seals which are preferably three in number and which are indicated in FIG. 37 by the references 186, 187 and 188.
  • the seal 186 takes support on the wing 162 of the intermediate profile 154 and, at the location of each of its ends, on the upper face of the upper arch 5 of the fixed structure.

  • the seals 186 and 187 are flexible and housed in cavities 189 and 190 which are delimited, for example, by the wings of a profile integral with the end of the opening 153. These two seals thus make the lateral part of the watertight opening structure at this location.
  • the seal 188 is preferably in the form of a lip. It is semi-rigid and rests against the wall of the gutter 181 of the lower profile 156. This joint 188 provides insulation between the internal and external parts of the structure and thus avoids condensation water inside as much as possible. of the book.
