    [0001] The invention relates to a profile for a joint, in particular a joint in the field of construction between two construction elements, or a joint between two parts of a machine, for example two parts of a vehicle. .
    [0002] A "seal" here designates a free space arranged between two walls respectively forming two bodies. A seal may be provided for different purposes. A seal may for example be provided so as to allow relative movement between the two bodies; in particular, an expansion joint may be provided to allow relative movement between the two bodies as a function of temperature changes. A seal is generally (but not necessarily) delimited by a bottom going from one body to another: in this case, the seal has the shape of a groove. The two bodies may be separate pieces or, on the contrary, be two parts of one and the same piece. A "profile" here means a product having a constant section along an axis or more generally along a curve, regardless of the section plane perpendicular to the axis or the curve. A joint profile is a profile whose function is to be placed at least partly in the joint to provide a function of connection between the two bodies located on either side of the seal, for example a sealing function. between these two bodies, or thermal insulation, etc. The invention more particularly relates to the case where the two walls 25 are respectively part of two bodies and are delimited by real or imaginary edges parallel to one another, and the bodies respectively have two surfaces said outer surfaces, substantially coplanar which extend from said ridges substantially in the lateral direction. The invention has been developed for joints of the latter type. In particular, in the field of construction (as in other areas) it is common to make walls and especially building facades from prefabricated elements. These elements are assembled to each other. Expansion joints are provided between the members so assembled to permit relative movement of these elements, and to avoid the occurrence of undesirable stresses therein. Due to the presence of these seals, it is necessary to provide profiles to ensure sealing between the various building elements. In a manner known per se, such profiles are made of elastically deformable material; they can thus be deformed so as to accompany the relative movements of the building elements. These profiles are arranged inside the expansion joints. However, these expansion joints have the disadvantage that their visual appearance is quite easily degraded as soon as one or other of the edges delimiting the joint is damaged and no longer has the originally intended nominal shape. The objective of the invention is therefore to overcome this drawback and to propose a profile which is able to be fixed in a joint, and which makes it possible to ensure at least one connecting function between the walls of the joint, even if the walls of the joint (and in particular the edges which delimit them) are partially degraded or have defects. This object is achieved by means of a profile extending in a curve and having at least one partition; said at least one partition extending in a lateral direction transverse to the curve and being able to be supported (elastic) on two parallel walls so as to maintain the profile in a seal formed between said walls, the profile comprising in addition to two fins, connected to said at least one partition, said fins extending respectively by at least 2 mm from each side relative to the remainder of the profile in the lateral direction. The term "partition" here designates a structure having a transverse section of any shape and which is capable of connecting one wall to another. The cross section of a partition is generally relatively thin and elongated, and may have a shape of straight segment, or a corrugated shape or the like. The support of the partition on the walls is generally an elastic support, to allow repeated relative displacements of the surfaces without this modifying the functions provided by the partition. In general, the ends of the partitions are intended to be brought into contact with the walls at substantially the same depth (with respect to the external surfaces of the two bodies between which the expansion joint is formed): this allows ensure that the forces applied by the walls of the gasket on the partition are offset and are oriented perpendicular to the walls. Between its ends, each wall may have a relatively arbitrary shape, and in particular a section that is not a straight segment. For example, in one embodiment, at least one partition has a V-shaped cross-section. (This characteristic, as the following characteristics of the profile characterize, unless otherwise indicated, the profile in a 'rest' state, without constraint, which is not the state of the profile when attached to the joint). This shape facilitates regular deformation of the partition (s) concerned. When the profile is placed in the seal, each partition is supported on the walls of the seal, and can perform one or more desired functions between these walls, for example a sealing function, etc.
    [0003] For example to ensure the seal between the walls, a partition may be constituted by a sealed plate, without holes, arranged to extend continuously from one wall to the other when the profile is placed in the seal. Furthermore, as previously stated, each of the fins of the profile protrudes by at least 2 mm, and if possible by at least 5 mm, with respect to the remainder of the profile, in the lateral direction. With this arrangement, the profile is adapted to be attached to the gasket in a flush position, in which at least one of the partitions is supported on the walls so as to fix the profile in the gasket, and the fins are placed in position. contact with external surfaces. It is further understood that the fins must be located on the same side of the partition, if there is only one partition, or at least one of the partitions if there are several partitions. Preferably, the fins are arranged on the same side with respect to all the partitions, when the profile comprises a plurality of partitions.
    [0004] Thus, when the profile is placed in a flush position, the fins because they are in contact with the external surfaces contribute to maintaining the profile in the desired position relative to the joint, even if the walls are partially damaged at the expense of the support partitions on them. In addition, the fins in this position mechanically protect the part with which they are in contact (or that they cover) and thus prevent the entry of foreign elements between the walls of the joint (water, various particles, etc.).
    [0005] Consequently, even if the edges delimiting the walls of the joint are partially degraded or have defects, the profile is able to provide the connection function or functions provided between the walls of the joint. Finally, advantageously according to the invention when the profile is fixed to the gasket in a flush position, the fins project from either side of the ridges to the right of the external surfaces. The fins thus make it possible to hide the edges of the external surfaces. Thus, whatever the state of these, the visual appearance obtained at the joint is satisfactory insofar as only the fins and the upper part of the profile are apparent (the seal and in particular the edges being hidden) . The aesthetic appearance of the portion of the profile that is outside the joint when the profile is in the flush position can be chosen according to the visual appearance sought at the location of the joint. In one embodiment, the profile is adapted so that, when in a flush position, the fins are supported on said outer surfaces. The fins thus exert pressure on the outer surfaces, which creates a relative seal at the point of contact between the fins and the outer surfaces and prevents the entry of water or foreign particles into the seal. For this purpose, preferably at rest, the fins extend from a central part of the profile in an oblique direction, away from both the central part of the profile and the external surfaces. This form increases the resistance of the profile to extraction out of the joint, compared for example with flat partitions. The fins may in particular be designed to be able, when the profile is in the flush position, to be slightly deformed so as to extend in the lateral direction against the external surfaces. The vanes may be connected to the bulkhead (s) in a variety of ways. In one embodiment, the fins are connected to the remainder of the profile in such a way that the profile is also suitable for being fixed to the joint in a second so-called recessed position, in which the fins are disposed between the walls of the joint, the said at least one partition being supported thereon. In the preceding sentence, the fact that the fins are disposed between the seal walls means that in this position of the seal and unlike the flush position of the seal, the fins no longer protrude outside the seal and in particular are not in contact with the seal. look at the external surfaces of it. In this embodiment, the profile is therefore likely to be used in at least two operating positions: the flush position and the recessed position. The profile is attached to the seal in the flush position when it is desired that the fins cover the edges of the seal.
    [0006] Conversely, the profile is placed in a recessed position when it is desired to make the profile as invisible as possible. In this embodiment, at least two arrangements are possible for the fins: the fins may themselves constitute the ends of a partition and bear against the walls when the profile is in the recessed position; or . the fins may extend substantially from the ends of a partition, and when the profile is in the embedded position, it is these ends which bear on the walls, the fins adopting inversely a folded position which allows them to be arranged between the walls of the joint. Whatever the arrangement of the fins, when the seal is placed in the recessed position the fins and their connection with the rest of the profile can follow elastic deformation or not.
    [0007] In one embodiment, the profile is arranged so that it can be placed in the embedded position without plasticizing or breaking. Laminating here designates a non-elastic deformation of the profile, following which the shape at rest of the profile is irreversibly changed. In this embodiment, the vanes are preferably connected to the rest of the profile by a relatively flexible connection, capable of elastically deforming when the profile is placed in the recessed position. Alternatively, the profile may be provided to undergo plasticization and / or partial breakage (with, for example, frangible portions) when placed in a recessed position. In one embodiment, the fins are connected to each other by a facade having a generally flat outer surface, adapted to be placed substantially at or slightly above said external surfaces when the profile is in the flush position (the expression "slightly above" means here that in the flush position of the profile, said generally planar outer surface is slightly offset from the plane of the outer surfaces of the opposite side of the joint). This facade may for example be in the form of blade or elongated plate. This facade forms a first barrier which helps to prevent the entry of air, water or foreign particles into the joint. This facade may be part of a partition capable of being placed in abutment on the seal walls in the flush position of the profile. But this facade can also be designed to be without support on the joint walls when the profile is flush: the latter embodiment allows greater freedom of operation for the connection between the fins and the rest of the profile. In the latter case, in some embodiments this facade in association with the fins may however be provided to bear on the walls of the seal when the profile is in the recessed position. Thus in these latter embodiments, when the profile is in a flush position, the facade does not bear against the walls of the joint; conversely when the profile is in the recessed position, the facade 35 bears on these walls.
    [0008] In one embodiment, the partition (s) are thin partitions, and the profile comprises at least two thin links, substantially perpendicular to the lateral direction Y, and which connect said fins to the partition (s).
    [0009] The term "thin" here means that a length / width ratio of the transverse section (respectively of the partition or the connection) is greater than 4. Furthermore, the partition or walls of the profile according to the invention have portions of support, intended to be supported on the seal walls when the profile is attached to the seal. When the profile comprises connections for connecting the fins to the partition or walls as presented above, in one embodiment, the support portions of at least one of the partition or walls above mentioned may be provided projecting on said links .
    [0010] These contact portions contribute to increase the resistance of the profile to the extraction out of the joint. These are generally elastic parts of the room, which allow an elastic support between the partition (s) and the walls of the joint. This elasticity then compensates for the effect of the bonds, which tend to stiffen the profile.
    [0011] In one embodiment, the support portions extend from a central portion of the profile in an oblique direction, away from the central portion of the profile while approaching the outer surfaces. This shape of the bearing portions allows the profile to have a relatively high holding force enabling the fins to bear on the outer surfaces. In one embodiment, the profile is integrally formed, in particular by extrusion. The invention also relates to an assembly formed by two surfaces between which is arranged a seal, and a profile as previously described, attached to the seal. The invention finally relates to a building or facade of a building, comprising at least one profile as defined above. The invention will be better understood and its advantages will appear better on reading the detailed description which follows, of embodiments shown by way of non-limiting examples. The description refers to the accompanying drawings, in which: - Figure 1 is a schematic perspective view of a profile according to the invention, in a first embodiment, in the unconstrained state; FIG. 2 is a diagrammatic cross-sectional view of the section of FIG. 1, in the unstressed state; - Figure 3 is a schematic view showing the section of Figure 1, mounted in a recessed position in a building facade; FIG. 4 is a schematic view showing the profile of FIG. 1, mounted flush in a building facade; - Figure 5 is a schematic view of a profile according to the invention in cross section, in a second embodiment, in the unconstrained state. In the different embodiments, the corresponding or identical bodies carry the same reference sign and are only described for the first embodiment in which they appear. A first embodiment of the invention will now be presented in connection with Figures 1 to 4 which have a profile for construction joint. The profile 10 is an extruded part formed integrally of elastic material. In the example presented, this material is a rubber-based compound, mainly EPDM or ethylene-propylene-diene monomer. The seal can also be made of a nitrile according to DIN 18541. It is a straight X-axis profile (the invention can however also be applied to profiles extending in any curve, for example). example packaged in coils). The profile 10 has a cross section (perpendicular to its axis X) of constant shape, shown in Figure 2. This section extends in two directions: - a direction of depth Z which is the direction in which the seal must be depressed to be attached to a joint; and the lateral direction Y, which is the direction both perpendicular to the X axis of the profile and to the depth direction Z. The profile 10 comprises four partitions 11, 12, 13, 14.
    [0012] Each partition has substantially the shape of a thin strip extending in the X and Y directions. However, the partitions also extend to a certain extent along the Z direction, in particular the partitions 12 and 13.
    [0013] The partition 11 plays a special role and is called the facade of the profile. It is placed at one end of the profile in the direction Z. The partitions 12, 13 and 14 are therefore located on the same side of the facade 11: Thus, the profile can be put in place in a joint with the partitions 12, 13 and 14 placed deeper than the partition or facade 11 in the joint. The term "width" for a partition is its measurement in the lateral direction Y. The partitions 12, 13 and 14 all have the same width E.
    [0014] The partition 11 is of greater width than the partitions 12, 13 and 14, for reasons which will be explained later. The profile 10 further comprises links 16A, 16B and 16C. These bonds are thin bonds of generally flat shape. They form substantially parallel blades extending generally in directions X and Z. The profile 10 has a plane of symmetry, namely the X-Z plane of equation "Y = 0" in the reference shown. The wall 16C is placed substantially in this plane of symmetry X-Z; the links 16A and 16B are placed at a distance from this plane, symmetrically to each other with respect to this plane. As a result, in a transverse section the links 16A, 16B, 16C and the partitions 11, 12, 13, 14 form a kind of grid (Fig.2). This grid forms six cells 21A, 21B, 22A, 22B, 23A, 23B. These cells appear in a transverse section like closed cells. The partition 11 is characterized by its ends which form fins 11A, 11B extending substantially in the lateral direction Y. Each of the fins 11A, 11B protrudes by a distance D, in the Y direction, relative to the rest of the profile. 10. In the embodiment shown, the fins 11A, 11B protrude by a distance D in the Y direction relative to the partitions 12, 13 and 14. In accordance with the invention, the distance D is at least equal to 2 mm; in this case it is 9 mm. As a result, the fins 11A, 11B are particularly elongate with respect to the ends of the partitions 12, 13 and 14. 5 Moreover, each of the partitions 12, 13 and 14 has at its ends elastic bearing portions (respectively 12A, 12B , 13A, 13B, 14A, 14B). These resilient support portions protrude on the links 16A and 16B and provided to bear against the walls of a seal when the profile is attached to a seal. The implementation of the profile 10 will now be presented in relation with FIGS. 3 and 4 which have the profile 10 mounted on a building facade 100. More specifically, the profile 10 is fixed in an expansion joint 50 provided on A facade of building 100. The joint 50 is a space formed between two surfaces 56A and 56B which constitute the walls within the meaning of the invention. These surfaces respectively belong to two building elements 52A and 52B (the two 'bodies' in the sense of the invention), each being of rectangular parallelepipedal shape.
    [0015] The building elements 52A and 52B are positioned relative to each other so that the side surfaces 56A and 56B face each other and parallel to each other. The surfaces 56A and 56B are delimited respectively by parallel edges 58A and 58B.
    [0016] Blocks 52A and 52B have outer surfaces 54A and 54B that extend away from each other in the Y direction from edges 58A and 58B. The profile 10 is provided to be placed in the seal 50 so as to seal it including air and water.
    [0017] The profile can be placed in the seal 50 in two positions: in the recessed position shown in Figure 3, and in the flush position shown in Figure 4. In both cases, the profile 10 is inserted into force in the seal 50 so as to place the bearing portions 12A, 12B, 13A, 13B, 14A, 14B of the partitions 12, 13 and 14 bearing on the walls 56A and 56B.
    [0018] The distance F between the walls 56A, 56B is smaller than the distance E. It is therefore necessary to compress laterally the profile 10. To facilitate the deformation of the profile 10, each of the partitions 12 and 13 has a cross section in the form of a 'V with the tip of the V directed in the direction of depression of the section 10 that is to say on the opposite side to the partition 11 having the fins 11A and 11B. Due to the V-shape of the partitions 12 and 13, the bearing portions 12A, 12B, 13A, 13B extend in respective oblique directions A and B (see arrows in FIG. 2) from the links 16A or 16B, 10 away from the central portion of the profile (located near the plane of symmetry XZ) and toward the outer surfaces 54A and 54B. The bearing portions 14A, 14B of the partition 14 also have this property. Since the profile 10 is formed of an elastic material, each of the partitions 12, 13 and 14 bears on the walls 56A and 56B. The partitions 12, 13 and 14 therefore seal the seal 50. The role of the partition 11 depends on the position in which the profile 10 is mounted. In the flush position (FIG. 4), the fins 11A and 11B of the partition 11 are in contact with external surfaces 54A and 54B but not necessarily supported thereon. As a result, in this position, while the partitions 12, 13 and 14 are supported on the walls 56A, 56B, the partition 11 is not supported on these walls. She plays a different role. By being in contact with the surfaces 54A, 54B, it contributes to keeping the profile 10 in position relative to the walls 56A, 56B, in addition to the partitions 12, 13 and 14, preventing rotation thereof around the surface. X axis and preventing it from sinking too much between the walls 56A and 56B. In addition, the fins 11A, 11B conceal the ridges 58A and 58B (as well as a portion of the outer surfaces 54A and 54B). As a result, the fins 11A and 11B hide these edges and thus mask a possible defect thereof. In the recessed position (FIG. 3), the profile 10 is pushed deeper into the seal 50 than in the flush position. The partitions 12, 13 and 14 are positioned between the walls 56A and 56B and play the same role as in the flush position. 301 76 84 12 The partition 11 on the other hand adopts a different shape and position and plays a different role (relative to the flush position): when the profile 50 is in the recessed position, the partition 11 has substantially the same function as the partitions 12, 13 and 14.
    [0019] The fins 11A and 11B, which are significantly longer than the bearing portions 12A, 12B, 13A, 13B, 14A, 14B, are provided to be pivotable and thus able to pass between the walls 56A and 56B, as shown in FIG. 3. In this position, they rest on the walls 56A and 56B. The partition 11 then performs a sealing function in the same way as the partitions 12, 13 and 14. The profile 10 is provided to be able to deform in an elastic manner, without plasticization or rupture, when it is placed in the joint that either in the flush position or in the recessed position. The partition 11 has (at rest) an outer surface 11S generally flat - and extending in the lateral direction. This surface 11S is intended to be placed substantially at or slightly above the outer surfaces 54A, 54B when the profile 10 is in the flush position. In the plane of symmetry X-Z, the surface 11S comprises a groove 25. This is provided to facilitate the deformation of the partition 11, in particular when the profile 10 is placed in the embedded position. Figure 5 shows a section 10 in a second embodiment of the invention. In this embodiment, the profile 10 has two links 16A, 16B between the partitions, but no third link 16C. In addition it has only three partitions 11, 12 and 13 instead of four. This embodiment can be adopted for profiles to be placed in joints of small width F. For example, this embodiment is suitable for joints of width equal to 10 mm, while the embodiment of Figures 1 to 4 is best suited for joints between 20 and 80 mm wide. Apart from the differences in size, the profile 10 is largely identical in both embodiments. The main differences between the two embodiments are as follows: As previously indicated, the section 10 of the second embodiment has only two links 16A, 16B. In addition, it comprises only three partitions 11, 12 and 13, and no partition 14. It therefore comprises only two cells 21 and 22.
    [0020] This example shows that a profile according to the invention can be made with a number of partitions and very variable connections. On the other hand, at rest the fins 11A and 11B extend obliquely in directions A ', B' which move away both from the plane of symmetry XZ and the partition 11 having the fins 11A, 11B (FIG. .5).
    [0021] The profile 10 may be positioned flush in the seal 50 so that the fins 11A and 11B deform with respect to their rest position and extend parallel to the lateral direction Y, and not in the directions A ' and B'. Under these conditions, the partitions 12 and 13 via their support portions 12A, 12B, 13A and 13B exert traction on the partition 11 in the direction Z, in the direction tending to drive the profile 10 between the walls 56A, 56B. Under the effect of this traction, the fins 11A and 11B rest on the outer surfaces 54A and 54B and thus advantageously provide a relative seal.
