- FIG. 1 illustrates a first construction device according to the invention, designated as a whole by the reference 100.
- This device of the double skin cladding type, comprises two lateral members 110 and 120, defining a spacer space 130, which is occupied by thermal insulation 140.
- the first lateral member 1 10 successively comprises, from the inside towards the outside, posts of which only 1 1 1 is illustrated, several C-shaped cladding boards 1 12, stacked one on top of the other, as well as a vapor barrier film 1 13.
- Various thermal insulation blocks 1 14 are also received in the interior volume of the trays 1 12.
- the second lateral member is formed by an external cladding 120, which can extend horizontally as in the example illustrated, but also vertically or obliquely.
- the various mechanical elements, listed above, are of conventional type and will not be described in more detail in the following.
- This device 100 further comprises several spacers according to the invention, which are regularly distributed along the cladding 120, for example every 1 .50 or 2 meters.
- Figure 1 illustrates one of these spacers 1, which generally has a Z shape in side view.
- this spacer comprises a core 2, which is placed in the spacer space 130, in contact with the insulator 140 or in the immediate vicinity of the latter.
- This core 2 is extended at both ends by wings 3 and 3 'protruding opposite one another. These wings, which are perpendicular to the core, are fixed for example by screwing, respectively on the lips 1 12 'of the trays, as well as on the cladding 120.
- the junction zone between the core 2 and each wing is reinforced by means of a succession of stampings 8, which will be called secondary in what follows.
- stampings 8 which will be called secondary in what follows.
- These secondary embossings which are evenly distributed along the core, are made in a manner known per se, for example by stamping. It can be provided that these stampings are present at a single junction zone between the core and one or other of the wings, or that the spacer is devoid of such secondary embossings.
- the core provides, in addition to a spacer function, a thermal function as explained at the beginning of the present description.
- a spacer function for this purpose, as shown in particular in Figures 2 to 4, it has a perforated zone 4.
- the latter is formed by a single perforated strip, placed in central position with reference to the main axis A1 of the spacer, namely its median longitudinal axis.
- the core also comprises two solid side strips 5 and 6, on either side of this perforated strip 4.
- the band 4 is composed of several rows of perforations, which extend parallel to the aforementioned axis A1.
- a perforation is a light that opens on the two opposite faces of the core. This perforation can be performed by any appropriate method known from the state of the art.
- this band 4 comprises between 3 and 12 rows.
- the number of rows is odd, which makes it possible to lengthen the path that the flow of heat must travel.
- the number of rows is more particularly greater than or equal to 5, preferably 5, which constitutes a good compromise between the thermal performance and the mechanical strength. Note that the invention takes the counterpoise of FR-A-2 288 194, which provides instead an even number of rows.
- Each perforation is elongated, namely that its main dimension, ie along the axis A1, is much greater than its transverse dimension. It has a generally rectangular shape, its edges being rounded in the manner of a semicircle. It can also provide straight edges, so that the perforation is strictly rectangular. Finally, we can provide edges having any intermediate shape, between a semicircle and two right angles.
- the rows are arranged in staggered rows, namely that the middle of a given perforation is located opposite the middle of the gap, separating the ends of two perforations of the or each adjacent row.
- the perforations 1 1, 31 and 51 placed at a first end of the odd rows, open on the first front edge of the core 2.
- the perforations 26 and 46 placed at the opposite end of the even rows, open on the other front edge of the core 2. Therefore, these end perforations have a shorter length than the other perforations. In what follows, they are called “open”, as opposed to all the other perforations which are thus called “closed”.
- the spacer shown in the figures has reduced longitudinal dimensions, for the sake of clearly illustrating its various constituent elements.
- the even and odd rows each have six perforations, respectively.
- a spacer according to the invention has a greater length.
- This number of perforations can vary in particular depending on the intended application, or the overall dimensions of the construction device.
- the end perforations open or not on a front edge, or even that they are not cut in the middle, at this front edge.
- the core 2 also comprises a succession of embossings 91 to 96, said principals as opposed to the secondary embossings 8, which extend transversely.
- the main axis of each embossing like those A93 to A95 in the figure 4, is a transverse axis of the spacer, perpendicular to the axis A1 above.
- Each embossing is carried out in a manner known per se, for example by a stamping process, in particular by rolling. Typically these embossings are formed after having made the various perforations in the core.
- embossings 91 to 96 are provided next to each other, along the main axis of the spacer. In other words, a single embossing is provided in a given longitudinal zone of the core. Thus, in each of these areas, if any of the embossings is projected along a transverse axis of the spacer, there is no overlap with another embossing. These embossings are traversed by certain perforations, as will be explained in what follows. It will be noted that the invention takes the counterpoise of FR-A-2 288 194, which provides lines of two or even three embossings, in certain areas of the spacer.
- FIG. 5 denotes S2 and S2 'the two parallel main surfaces, which define the thin wall constituting the core 2.
- the embossings can be formed in relief, like those 92, 94 and 96 in FIG. that their surface protrudes beyond a first surface, in this case that S2. They may also be recessed, such as those 91, 93 and 95, namely that their surface protrudes in the opposite direction, beyond the other surface S'2.
- the embossings are alternated, namely that they are successively formed in relief and hollow.
- This measure is advantageous because it gives a symmetrical character to the spacer and a homogeneous behavior. In particular, the risks of mechanical weakness in one or the other direction are reduced. Moreover, this alternation is beneficial for the overall aesthetics of the retractor.
- the invention takes the counterpoise of FR-A-2 288 194, which indicates that all the embossings must project from the same side of the soul.
- L2 the width of the core, as well as L4 to L6 the respective widths of the bands 4 to 6.
- the ratio L4 / (L5 + L6) is between 0.16 and 2.10, in particular between 0.24 and 0.63.
- the width of the perforated strip corresponds to the distance between the opposite side edges, belonging to the perforations of the end rows R1 and R5.
- the perforated strip is not in the central position.
- the width L5 or L6 of one of the solid strips is then greater than the width L6 or L5 of the other of these strips.
- the ratio L4 / (L5 + L6) is similar to that described in the previous paragraph.
- the web of the spacer has two perforated strips, a central solid strip separating them, and two lateral solid strips. These different bands are arranged symmetrically with respect to the median longitudinal axis.
- the ratio between the total width of the perforated strips and the total width of the solid strips is similar to that described above with reference to FIG. 4. In this case the width of the perforated zone corresponds to the distance between the opposite edges of the perforations. end of this area.
- each perforation longitudinal dimension, or length of each perforation, ie greater distance between the opposite edges of this perforation, along the axis A1. Without limitation, this length is typically between 50 and 100 mm, especially between 75 and 85 mm;
- transverse dimension or width of each perforation.
- this width is typically between 0.5 and 10 mm, in particular between 2.5 and 3.5 mm;
- all the closed perforations have the same length LP and all the spacings EL are identical. Consequently, the pitch between two adjacent closed perforations is identical over the entire perforated strip, which makes it possible to standardize the performance of the spacer.
- the pitch PE between two adjacent embossings has the same value P as the pitch between two closed perforations, as presented above.
- the embossings are distributed regularly along the soul. This makes it possible to confer good uniformity on the mechanical behavior of the spacer, while ensuring a satisfactory possibility of industrial manufacture of the spacer and its embossings.
- the embossings are traversed by certain perforations.
- the relief embossment 94 is traversed by two perforations 24 and 44 whereas, in FIG. 7, the hollow embossment 93 is traversed by two perforations 23 and 43.
- These perforations extend from one end to the other. of these embossings, namely that they connect their opposite side edges 93A and 94A.
- 23 ', 24', 43 'and 44' are also noted on the edges of the various perforations, which follow the profile of the embossing.
- each embossing is crossed only by perforations belonging to even rows R2 or R4.
- each lateral edge of these embossings is advantageously distant from the different odd rows. There is therefore, between the edges facing the embossing and these odd perforations, an interval I for example greater than 1 mm.
- the core 2 is embossed in its zone "less perforated", which is advantageous mechanically.
- Figures 1 1 A and 1 1 B schematically illustrate this feature of the invention for spacers having three ( Figure 1 1 A) or five ( Figure 1 1 B) rows of perforations.
- FIG. 11A only the row R2 of perforations passes through embossings in the zone of the core 2 where only the row R2 is located.
- FIG. 11B similarly, only the zone of the core where the rows R2 and R4 are located is provided with embossings.
- L93 and H93 respectively denote the length and the height, or depth, of each embossing, for example that 93.
- L93 is defined as the greatest distance, along the axis A93, between the longitudinal edges. opposite 93B of this embossing. These edges correspond to the places where the opposite surfaces of the embossing move away from the plane of the main surfaces S2 and S'2 of the core.
- the length L93 of each embossing which is typically between 10 and 200 mm, is greater than or equal to the width of the perforated strip 4, as defined above. It can be expected that the embossings extend beyond this band, to the vicinity of the junction of the core 2 with the wings 3 and 3 '.
- the height H93 is defined as the distance, along an axis perpendicular to the surface S2, between this surface and the bottom of the embossing. This height is typically between 1 and 5 mm.
- the width L'93 or L'94 is defined analogously as the greatest distance, along the main axis of the spacer, between the opposite lateral edges 93A or 94A of each embossing. As seen above, this width, which is typically between 3 and 30 mm, is advantageously less than the transverse spacing ET.
- the Applicant has identified that the value of the LP / EL ratio is more particularly important.
- the respective thermal and mechanical behaviors of the spacer do not evolve in the same way, with the variations of this LP / EL ratio.
- the thermal performance of the spacer improves until this ratio reaches a value close to 4, then evolves substantially more.
- the mechanical strength deteriorates in a globally continuous manner, as this ratio grows, without the value 4 constituting a remarkable point.
- LP / EL is between 3.70 and 4.30 (relation 1).
- LP / EL is between 3.90 and 4.10, in particular between 3.95 and 4.05, in particular equal to 4.
- the relation 1 is verified on at least a part of the closed perforations of the strip.
- it is checked by at least 50%, in particular at least 90%, preferably by all these closed perforations.
- certain perforations do not verify this relation 1, they are in particular those located at longitudinal ends of the spacer, or those belonging to the lateral rows of the perforated strip, such as R1 and R5 in the illustrated example.
- the ratio between the width TP of a perforation, for example 21, and the spacing AND separating this perforation 21 and the perforation opposite 31 of the adjacent row to be close to the value 1. This value ensures a satisfactory compromise between the thermal performance of the spacer and its mechanical strength.
- TP / ET is between 0.66 and 2.1 (relation 2).
- TP / ET is between 0.80 and 1 .33, in particular equal to 1.
- all the open and closed perforations have the same width TP, while all the spacings ET are identical.
- the spacer 1 of the first embodiment has a Z shape in side view.
- the spacer according to the invention has different shapes.
- this spacer comprises a core 62 extended at both ends by wings 63 and 63 'projecting in the same direction.
- the core 62 has a perforated strip 64, as well as two solid strips 65 and 66.
- the mounting of this spacer 61 is similar to that of the spacer 1, namely that the core is placed in the spacer space 130, while the wings are fixed respectively on the lips 1 12 'of the trays, as well as on the cladding 120.
- Another variant involves a spacer 71 in the shape of Sigma, which differs from that 61 only in that its core 72 has a median recess, including the perforated strip 74.
- the other constituents 73, 73 ', 75 and 76 are identical to those 63, 65 and 66.
- a spacer 81 in the shape of Omega is therefore provided with two webs 82 and 82 ', each of which has a perforated strip 84, 84', and two solid strips 85 and 86, 85 'and 86'. It further comprises three wings, of which a first 83 connects the two souls, a first side thereof, and the other two 83 'and 83 "protrude in opposite directions, from the other side of these souls In use, the souls are placed in the spacer space 130, the first wing 83 is fixed on the lips 1 12 ', or on the cladding 120, while the other two wings 83' and 83 "are fixed on the cladding 120, or on the lips 1 12 '.
- the different wings may have a straight edge.
- at least one of these wings may have a fallen edge, namely that its free end is provided with a return forming a right angle with respect to this wing.
- the wings 3, 3 ', 63, 63' and 73 ' are on a straight edge, while those 73, 83' and 83 "are on board.
- FIG. 9 illustrates a second construction device according to the invention, designated as a whole by the reference 200.
- This device comprises two lateral members, consisting respectively of a concrete wall 210 and a cladding 220, similar to that 120.
- two members 210 and 220 define an interspace 230, which is occupied by a thermal insulator 240.
- This device 200 further comprises several spacers 1 as described above, the core 2 is received in the spacer space 230 and whose wings 3 and 3 'are screwed respectively to the wall and cladding.

- FIG. 10 illustrates a third construction device according to the invention, designated as a whole by the reference 300.
- This device placed on the roof of a building, comprises two lateral members 310 and 320, defining an intermediate space 330, which is occupied by thermal insulation 340.
- the first lateral member 310 successively comprises, from the inside towards the outside, faults of which only one 31 1 is illustrated, a plurality of U-shaped plates 312 placed next to each other, and a film covering Steam 313.
- Various thermal insulation blocks 314, as well as spacers 315 shaped Omega, are also received in the interior volume of the trays 312.
- the second lateral member is constituted by a metal cover 320, formed of classic way by a ribbed steel sheet.
- This device 300 further comprises at least one spacer 1 as described above, the core 2 is received in the interspace 330 and whose wings 3 and 3 'are screwed respectively on the spacers and the metal cover.
- Several identical spacers may be evenly distributed on the surface of this device.
- the trays 312 may be replaced by a ribbed steel sheet, similar to that constituting the cover 320.
- the construction device is a thermal wall, of the type described in WO-A-98/45545.
- This wall comprises two lateral surfaces defining an intermediate space, in which at least one spacer according to the invention is received.
- the invention can find its application to a renovation of cladding. For this purpose it starts from an existing cladding and has on the outer shell of the latter, several spacers according to the invention. A new shell is then placed against these spacers, so as to form an interspace between this new shell and the existing shell. These two shells are mutually secured, for example by riveting, while the above spacer space is filled by means of a suitable insulator.
