Definitions

  • the invention relates to a module and a storage module for holding tanks.
  • modules are known formed of an assembly of half-storage modules by vertical stacking of the half-modules between them and by horizontal junction edge-to-edge of the half-modules adjacent.
  • Such a half-module is generally made of a single piece formed of a horizontal plate-shaped grid and vertical studs which extend from a large face of the plate.
  • the invention thus provides a plate and separate pads which are fixed to each other only for the realization of a half-module. It is thus possible to transport and manipulate separately the plate and the pads, thus alleviating the arduous task of the staff.
  • the set of pads intended to be mounted on the plate can also be handled and transported at one time or by sub-set of pads or pad by pad according to the weight of the latter.
  • a single plate allows to accommodate on its two opposite sides two sets of pads where, in the prior art, thanks to its configuration, two plates were necessary; the thickness and therefore the size of such an arrangement are reduced.
  • the invention also relates to a storage module for retention basin, characterized in that it comprises two storage half-modules such as briefly exposed above which are mounted head to tail and assembled with each other by cooperation of each stud of a first half-module storage respectively with the corresponding pad of the second storage half-module and, more particularly, by cooperation of the projecting element and the through hole of each pad of a first storage half-module respectively with the through hole and the protruding element of the corresponding stud of the second storage half-module.
  • This arrangement or stack of half-modules is less high, less bulky, lighter and therefore less painful to assemble than in the prior art (half-modules and conventional modules) due to the use of two large opposite faces of the plate of the first half-module.
  • a storage tank half-module comprises, on the one hand, a grid-shaped plate ( figure 1a ) and, on the other hand, a plurality of pads assembled on the plate, such as the stud 30 ( figure 2a ).
  • the plate 10 is provided, in its thickness, with a plurality of main through openings, for example four referenced 12a-d (having for example each a generally rectangular shape), and a multitude of secondary through openings 14.
  • the main openings 12a-d each have a passage section that is very much greater than that of the secondary openings (at least in a ratio of 10).
  • the main openings 12a-d are in this example arranged at the four corners of the rectangle formed by the plate leaving clear a central corridor 16, while the secondary openings 14 are mainly arranged between the main openings, in the central corridor and between two openings adjacent principal 12a-b and 12c-d.
  • the plate 10 has two large opposite faces of which only the upper face 10a or first face is shown on the figure 1a .
  • the plate is provided on the first face 10a of first fastening means which are located in a channel 18a-d respectively surrounding each main opening 12a-d and which follows its contour.
  • the channel makes it possible to stabilize the stud which will be fixed there.
  • the figure 1b shows two types of first fixing means: male means and female means which are intended to cooperate each with second complementary fastening means secured to the studs such as that of the figure 2a . It should be noted that all the fixing means present on the plate and on the pads are not necessarily used for mounting according to the plate and stud configurations envisaged.
  • the channel 18a is delimited by two parallel walls vis-à-vis, one inside 18a1, defines the outline of the main opening 12a and the other, 18a2 exterior, carries the fastening means.
  • the outer wall 18a2 comprises two large opposite sides and two adjacent small opposite sides. Each small side carries for example a male fastening means 20a and a female fastening means 20b. Each large side carries for example four identical fastening means 20c.
  • four fixing means 20c are represented on the figure 1b but only two are used for the mounting of pads on the upper face 10a, the other two being used for the mounting of pads on the opposite face not visible here.
  • the second large opposite face of the plate has a structure almost identical to that of the first face 10a.
  • the stud 30 illustrated at Figures 2a and 2b comprises a base 32 and a side wall 34 which extends axially from and away from the base to an end wall 36.
  • the wall 34 extends in a narrower direction towards the wall end to give the pad a generally frustoconical general shape.
  • the end wall 36 is partially closed and is provided as attachment members with a projecting element 38 of axial extension which is perforated and an adjacent through hole 40.
  • the projecting element 38 and the hole 40 of the stud are intended to fit respectively with the hole and the projecting element of another stud in the manner of a tenon-mortise type assembly (complementary fastening elements). one of the other).
  • the projecting element 38 has for example a truncated pyramid shape and is provided with two lights 38a-b in two opposite faces and a central opening 38c at the top.
  • the end wall 36 is also pierced with other openings / orifices for the flow of water.
  • Two additional attachment members 40a-b (forming a retainer) are arranged in an area located inside the stud withdrawn from the through hole, at the periphery thereof and in facing relation. These bodies are intended to fit into the lights 38a-b of a projecting element 38 fitted into the hole.
  • the wall 34 is profiled in a cross section so as to stiffen the stud.
  • the base 32 of the stud forms a peripheral portion of which a flat zone 32a surrounds a central opening 42 communicating with the inside of the stud (seen from below the figure 2b ).
  • the peripheral portion 32 is also shaped so as to form, from the plane zone 32a, an outer rim 45 rising upwards ( Fig. 2a ) and which defines with the outer wall 34 of the stud a groove 44 which borders the stud at its base.
  • the outer flange 45 carries second fastening means distributed on the different sides of the flange and which are intended to cooperate with the first complementary fixing means of the plate.
  • a male means 46a is for example in the form of an elastic tab ( figs 2a and 2c ) provided at its free end with a ramp 46a1 ending in a straight edge 46a2.
  • This means 46a is intended to cooperate with a first complementary fastening means 20b of the plate as shown in FIG. figure 2e (partial enlarged view in perspective and in section).
  • the ramp 46a1 slides on the upper edge and the vertical edge 20b1 which stops by a lower drop 20b2 forming a recess into which penetrates the elastic tab 46a.
  • the upper edge 46a2 is in axial abutment against the upper edge of the recess 20b2 forming a retainer, thus preventing axial shrinkage (locking of the two complementary latching means relative to one another).
  • the male means 46a are offset relative to each other on either side of a median plane passing through the short sides of the stud ( Fig. 2b ).
  • the female means 46b are four in number on the long side and are intended to cooperate with the plate means 20c ( fig 1b ) as shown on the figure 2f (partial enlarged view in perspective and in section).
  • the means 46b have a ramp 46b1 on their outer surface which cooperates by sliding on a complementary ramp 20c1 of the complementary means 20c which is here an elastic blade.
  • the coverslip elastic 20c is shaped to include, after the ramp, a return 20c2 towards the inner wall 18a2 of the channel 18a, thus conferring on the upper part of the means 20c a triangular profile.
  • the ramp 20c1 is erased when sliding above the ramp 46b1 and returns to its initial position after crossing the lower edge of the ramp by the ramp 46b1.
  • the free upper edge 46b2 is thus blocked by engagement with the return 20c2 which forms an axial retaining element and prevents any axial shrinkage (locking of the two complementary snap-fastening means with respect to each other).
  • Keystrokes 48a-c are provided on the long sides of the peripheral flange 45 (for example two on one side and one on the opposite side) for mounting the stud in the correct position around the opening 12a ( figure 1b ) on complementary polarizers 50a-c arranged in the channel 18a.
  • the figure 3 illustrates a half-module 60 which is formed from the plate 10 ( figure 1a ) on which four studs 30 were mounted via the first and second complementary fastening means of the plate and the pads respectively.
  • the pads are fixed / locked to the plate, the flat area 32a of the peripheral portion 32 of each pad is supported on the upper edge of the inner wall 18a1 of each opening 12a-d.
  • the central opening 42 of each stud is thus disposed opposite each main through opening 12a-d.
  • the studs 30 are arranged two by two adjacent to one of the short sides or edges of the plate 10 to leave a free space large enough for the central corridor 16 between pairs of adjacent studs.
  • the pairs of salient element 38 and hole 40 of each pair of adjacent studs are mounted head to tail.
  • the studs arranged along the diagonals have the same arrangement (order) of alignment of the projecting element 38 and the hole 40.
  • This assembly is facilitated by the presence of the polarizers 48a-c and 50a-c.
  • This assembly thus makes it possible to have only one type of half-module to assemble (only one reference to manage in stock), unlike a half-module in which the pads all have the same arrangement (order) of alignment of the projecting element and the hole.
  • the half-module 60 of the figure 3 (first half-module) can thus be assembled with an identical half-module referenced 62 (second half-module) which is mounted head-to-tail from above as shown in FIG. figure 4 .
  • the two half-modules 60 and 62 are easily assembled with each other by means of their matching pads fixed to each other via the complementary coupling members 38, 40 (interlocking means) of each stud.
  • the assembly thus assembled / stacked is a storage module 70 in which the channel 16 can be used for the passage of an inspection tool (camera ...) or as a drain.
  • the figure 5 illustrates the assembly of several half-storage modules. More particularly, four additional studs 30 are fixed under the second large face 10b of the plate 10 of the first half-module 60 of the figure 4 identical to the mounting of the pads on the first face 10a.
  • a third half-module 80 identical to the half-module 60, is mounted head-to-tail and assembled with the additional pads 30 fixed to the face 10b identically to the assembly of the half-modules 60 and 62.
  • the plates and the pads being manufactured separately, different materials can be used to adapt to the types of mechanical forces to which the plates are subjected (lateral forces) and the studs (axial or vertical forces) and therefore in order to optimize their mechanical characteristics.
  • the plates and the pads are for example made by injection molding with a mold for the plate 10 and one for the stud 30.
  • Each stud carrying the two types of fasteners with the other pads there is only a type of plot, which facilitates the management of references in stock.
  • the pads 30 are thus larger than in the prior art (each pad has for example a section at the base which is 200x400mm instead of about 200x200mm in the prior art), which reduces the number of mounting operations of pads on a plate.
  • the plates, on the one hand, and the pads on the other hand can be stacked separately to optimize the transport and the storage.
  • the handling of the stacked elements is also facilitated because of a lower weight than in the prior art (plate and pads indissociable).
  • the half-module can be transported already assembled or partially assembled.
