Definitions

  • the invention relates to a modular confinement assembly, usable in particular in the nuclear industry, in order to delimit an evolving closed volume which is easily decontaminable and the dismantling of which produces a limited quantity of waste.
  • the modular confinement assembly according to the invention is particularly suitable for use in the nuclear industry.
  • it can be used to delimit a closed volume around contaminated nuclear equipment, the dismantling of which is desired.
  • This containment system can also be used for storage or in a non-hostile environment.
  • Document EP-A-0 161 133 describes a modular confinement assembly formed of flat rectangular panels comprising continuous peripheral edges, of U-shaped section, formed of two wings at right angles.
  • the adjacent panels are assembled edge to edge, either directly when they must be placed in the same plane, or by means of angles when they must form a right angle between them.
  • This assembly is ensured by organs of the bolt type passing through holes formed opposite in the first wing of the edges, which forms a right angle with the rectangular panels.
  • the second edge flange is used to fix stiffeners on the panels.
  • the edges of the panels are placed outside the volume delimited by the containment assembly, so that the interior surface is smooth and easily decontaminable.
  • the subject of the invention is precisely a modular confinement assembly whose original design makes it possible to reduce the number of different parts used to form this assembly, to simplify the structure of these parts and to increase the possibilities of assembly without creating large quantities of waste and without the ease of decontamination being seriously affected.
  • a modular confinement assembly comprising rectangular panels having at least one substantially planar peripheral zone carrying a continuous peripheral wing and means for assembling these panels edge to edge, taking support on said wings, characterized in that the peripheral wing of each panel is oriented substantially at 135 ° relative to the peripheral zone, and that the assembly means comprise cross-section bars in the shape of an isosceles right triangle, bearing clamping members oriented along the bisector of the right angle of this isosceles right triangle.
  • the panels can be assembled edge to edge either in the same plane, between them an internal angle of 90 °, or by forming between them an internal angle of 270 °.
  • One or more panels can also serve as an interior partition. The peripheral edges of these panels are then pinched between the adjacent edges of two panels assembled together in the same plane.
  • the assembly means are tightened from the outside. The interior of the enclosed volume delimited by the assembly is practically smooth and easily decontaminated.
  • the assembly means comprise a first type of bars, carrying clamping members on the side of the right angle of the isosceles right triangle, and a second type of bars, bearing members bridle on the hypotenuse side of the isosceles right triangle.
  • the bars of the first type are used to join edge to edge two neighboring panels located in the same plane while the bars of the second type are used to join edge to edge of panels forming between them an angle of 90 ° or 270 °.
  • the two types of bars can be obtained using identical bars carrying identical clamping members arranged in opposite directions depending on the type of bars concerned.
  • each clamping member comprises a threaded rod on which is screwed a nut.
  • Truncated angle angles can be mounted on these threaded rods, between the nuts and the wings of the adjacent panels.
  • the wings of the panels have open notches for the passage of the clamping members. These notches are used when the panels are assembled edge to edge to form an internal angle of 90 ° between them. Indeed, the wings of the panels adjacent are then pressed against each other and compressed by the clamping members which pass through the open notches.
  • a first type of rectangular panel is used, the length of which is twice the width, and a second type of square panel, the side of which is equal to the width of the panels of the first type.
  • the bars then have a length equal to or slightly less than the width of the panels of the first type.
  • At least one of the panels of the first type is equipped with a door.
  • the panels are made of a transparent material such as polyvinyl chloride.
  • Figure 1 illustrates by way of example one of these configurations. It illustrates the relatively limited number of different parts that it is necessary to use to make a confinement assembly of relatively complex shape.
  • These parts essentially comprise two types of rectangular panels, as well as the parts constituting the means for assembling these panels.
  • a first type of rectangular panel designated by reference 10 in FIG. 1, is formed from panels whose length is twice the width. In a preferred modular configuration, the width of these panels is 1 m and their length is therefore 2 m.
  • the second type of panel designated by the reference 12 in FIG. 1, consists of square panels whose side is equal to the width of the rectangular panels 10. In the example described, the length of the sides of these panels 12 is therefore 1 m.
  • the panels 10 and 12 are preferably flat panels, at least in their peripheral zones. They are made of a transparent material such as polyvinyl chloride, capable of being easily decontaminated and having satisfactory rigidity as well as a relatively low unit weight (for example around 15 kg for the panels 10 of larger dimensions).
  • each of the panels 10 and 12 carries a peripheral wing continuous, oriented substantially at 135 ° relative to this peripheral zone.
  • This peripheral wing is designated respectively by the reference 10a for the panels 10 and by the reference 12a for the panels 12, as illustrated in FIGS. 2 and 3.
  • panels 10 and 12 can be used interchangeably to form the side walls, the roof or interior partitions of the containment assembly that it is desired to make, as illustrated in FIG. 1.
  • At least one of the rectangular panels 10 used to form the lower part of the walls of the containment assembly may include a door 14 allowing operators to access the enclosed volume 15 (Figure 2) bounded by this containment set.
  • panels 10 and 12 can be cut on demand, or replaced by a vinyl sheet 16 ( Figure 1).
  • the assembly means by means of which the panels 10 and 12 are assembled edge to edge to form the desired containment assembly also include a limited number of parts bearing on the wings 10a and 12a of the panels 10 and 12 and the mounting of which is done from the outside of the containment assembly.
  • the wings 10a and 12a of the panels forming the walls and the roof of the assembly are oriented towards the exterior of the closed volume 15.
  • the assembly means which are used to assemble edge to edge the panels 10 and 12 according to the desired arrangement are of two types but advantageously consist of the same parts.
  • the assembly means comprise a bar with a section substantially in the form of an isosceles right triangle, as well as clamping members carried by this bar and oriented along the angle bisector. right of this isosceles right triangle.
  • each of the bars has the same length, preferably slightly less than the width of the panels 10 and the side of the panels 12 (that is to say 0.945 m in the example described).
  • each of the bars carries two clamping members, near its ends.
  • Each of these clamping members 20 comprises a threaded rod 22 fixed in the bar 18, as well as a nut 24, screwed onto this threaded rod.
  • the nuts 24 are preferably butterfly nuts.
  • the threaded rods 22 are preferably fixed in a removable manner in the bars 18, for example by screwing.
  • Each of these clamping members 28 comprises a threaded rod 30 fixed to the bar 26 and a nut 32 screwed onto the threaded rod 30.
  • the nuts 32 are advantageously butterfly nuts.
  • the threaded rods 30 are detachably fixed in the bars 26, for example by screwing.
  • the bars 18 and 26 are advantageously identical to each other, as are the threaded rods 22 and 30 and the nuts 24 and 32.
  • the two types of bars 18 and 26 are then distinguished only by the fact that the threaded rods 22 and 30 are screwed in the opposite direction into the threaded holes formed for this purpose in the bars 18 and 26.
  • angles 34 and 36 are identical and include ovalized holes for the passage of the threaded rods 22 and 30. They exist in two lengths (0.945 m and 1.945 m in the example considered).
  • the bars 18 and 26 are advantageously made of polyvinyl chloride.
  • the threaded rods 22 and 30, the nuts 24 and 32 and the angles 34 and 36 are made of a metal such as stainless steel.
  • the panels 10 and / or 12 must be assembled edge to edge so that they lie in the same plane, vertical or horizontal as the case may be.
  • the assembly is then carried out as illustrated in A in FIG. 2, by means of the bars 18 carrying the clamping members 20 projecting from the side of the right angle of the isosceles right triangle formed in section by each of the bars 18.
  • the panels to be assembled being arranged in the same plane, their wings 10a and / or 12a are placed side by side and turned towards the outside of the closed volume 15 delimited by the confinement assembly to be produced. These wings are applied against the faces of the bars 18 corresponding to the sides of the right angle of the isosceles right triangle formed in sectioon by these bars.
  • a symmetrical angle iron 34 with a truncated angle is interposed between the nuts 24 and the wings of the panels.
  • the tightening of the nuts 24 then has the effect of tightening the wings 10a and / or 12a between the angle iron 34 and the bar 18.
  • the latter is then turned towards the inside of the closed volume 15 delimited by the containment assembly, such so that the hyposenuse of the isosceles right triangle which it forms in section is substantially aligned with the planes of the panels 10 and / or 12 thus assembled.
  • the assembly is carried out by means of bars 26 equipped with clamping 28, without using any angle 34 or 36 with truncated angle.
  • the peripheral wings 10a and / or 12a of the panels to be assembled are oriented towards the outside of the enclosed volume delimited by the containment assembly which it is desired to produce, by applying these wings one against the other.
  • the threaded rods 30 are then fitted into open notches 38 formed for this purpose on the edges of each of the sides 10a and / or 12a of the panels.
  • the spacing between these notches 38 is equal to the spacing which exists between the two threaded rods 30 carried by each of the bars 26.
  • the assembly of the containment assembly involves the formation of an outgoing angle of 90 °, that is to say an internal angle of 270 °, as illustrated in C on Figure 2, the corresponding panels are assembled by means of bars 26 carrying clamping members 28, by interposing a symmetrical angle iron 34 with a truncated angle.
  • the wings 10a and / or 12a of the panels to be assembled are then placed end to end and in the same plane, by passing the threaded rods 30 between the adjacent edges of these wings and by placing the bar 26 inside the enclosed volume. delimited by the containment unit to be produced.
  • the tightening of the nuts 32 on the threaded rods 30 then has the effect of pinching the sides 10a and / or 12a of the panels to be assembled between the angle 34 with a truncated angle and the bar 26.
  • the assembly is practically the same as that which was described previously in A, but the wing 10a or 12a of the panel intended to form the interior partition is interposed between the bar 18 and one or the other. wings 10a and / or 12a of the two panels adjacent to form the bulkhead or roof. To take account of the thickness of the wing 10a and / or 12a of the panel forming the partition, the holes formed in the angles 34 and 36 for the passage of the threaded rods 22 and 30 are ovalized.
  • bars 18 and 26 have a modular length, for example 0.945 m in the embodiment described, the different types of assembly which have just been described with reference to parts A, B, C and D on Figure 2 are generally ensured by placing end to end several bars of the type concerned.
  • the modular confinement assembly thus obtained delimits a closed volume whose interior surface is practically smooth with the exception of the bars 18 and 26 in the case of the assemblies illustrated in A, C and D. Only interstices remain at the ends of the bars 18 and 26 and when four panels have a common angle, as illustrated at E in FIG. 1 and shown in detail in FIG. 3.
  • this last figure is a view taken from inside the enclosed volume delimited by the confinement assembly, in region E which corresponds to the connection between two walls forming between them an interior angle of 270 °, at the junction in the vertical direction between two panels 10 and / or 12.
  • each of the left and right walls is formed by a square upper panel 12 and a rectangular lower panel 10.
  • Each group of panels 10 and 12 thus formed is assembled by means of a bar 18 and clamping members 20, as illustrated in A in FIG. 2.
  • junctions between the panels 10 and 12 forming the left and right walls are located at the same level and the upper walls 12 as the lower walls 10 are joined together by means of bars 26 and clamping members 28 as illustrated in C in FIG. 2.
  • this arrangement is to leave a gap 39 between the ends of the bars 18 and 26 corresponding to the junction between the four panels 10 and 12.
  • this gap 39 is closed by gluing a rectangular piece 40 cut from a strip adhesive on the inside of the four adjacent panels 10 and 12.
  • the dimensions of the part 40 are chosen so as to completely close the gap 39.
  • gap 39 A gap comparable to gap 39 is found at each junction between two, three or four adjacent panels, whether or not these panels are in the same plane. In all cases, this gap is closed by means of a piece of adhesive tape glued to the interior faces of the panels as illustrated in FIG. 3.
  • the self-supporting nature of the modular confinement assembly according to the invention also provides great security and appreciable comfort. Safety is also ensured by the fire resistance of the panels and their transparency. This last characteristic is also appreciable to facilitate lighting, display and communication between the interior and exterior of the enclosed volume. Finally, it should be noted that specific panels can be integrated on demand by transforming the modular panels 10 and 12.
