Description

Connection clip

The present invention relates to a connecting clip for connecting a first wall already at least partially built to a second wall under construction, which first and second walls being separated by a hollow arranged to be partially filled with thermal insulation, said second wall being constructed using construction elements, which fastener comprises a fixing element and an anchoring element, which fixing element being arranged to be inserted and fixed in a cavity present in one face of the first wall facing the second wall, which fixing element is connectable to the anchoring element by a junction member.

Such a connecting clip is known from patent FR 2 694 586. The known connecting clip is applied in an expansion plug which itself is pressed into a cavity in the first wall. The known fastener also includes an anchoring element which is located in the extension of the fixing element. The connecting clip is used to establish a connection between the first and the second wall, which are separated by a space used inter alia for the ventilation of the walls.

A disadvantage of the known fastener is that it is not suitable for construction where the second wall is made by masonry with a thin horizontal joint. In this type of construction we use anchoring elements which are relatively thin so that we can place them in the mortar or glue joint which is only at most 5mm thick. Practice has shown that this can lead to problems. Indeed during the construction of the second wall it can move. This will cause the anchor to push back the mortar or glue used for construction, creating cavities around this anchor. Over time, the mechanical stresses exerted among others by the wind on the second wall are not sufficiently absorbed, thus leading to a fall of the second wall.

BE2018 / 0090

-2The purpose of the invention is to provide a connecting clip, in particular for walls with a thin horizontal joint, which offers better resistance to the stresses exerted on the second wall both during its masonry and during its existence.

To this end a connecting clip according to the invention is characterized in that the junction member is arranged to allow a height adjustment between the anchoring element and the fixing element, which anchoring element comprises at minus a retaining member arranged to be secured to the building element on which it will be applied. The fact that the junction member is arranged to allow a height adjustment between the anchoring element and the fixing element makes it possible to adjust the height at which the anchoring element will be able to join with the building element on which it will be applied and thus correctly position it in relation to the second wall. This ensures that the transfer to the first wall of a stress exerted on the second wall is correctly carried out. The presence of at least one retaining member allows this retaining member to be secured to the second wall, thereby helping to keep it in place, especially during its construction.

A first preferred embodiment of a connecting clip according to the invention is characterized in that the retaining member comprises at least one segment which is curved, or can be curved by folding, to allow the member to be secured retained with the building element on which it will be applied.

A third preferred embodiment of a connecting clip according to the invention is characterized in that the anchoring element is formed by a first wire bent according to a first predetermined geometry, which first geometry is formed by a first and a second leg each provided with a foot, said feet forming the retaining members, which legs being interconnected by a loop in the form of an eyelet. A relatively simple and easy-to-install embodiment of the connecting clip is thus obtained. It suffices to pass the loop in the form of an eyelet over the end piece to place the anchoring element on the junction member. The presence of the hook means that the eyelet-shaped loop can slide along the hook.

Preferably the hook and the eyelet-shaped loop are dimensioned so that the eyelet-shaped loop can be engaged around the hook, in particular in a recess formed in the hook. The presence of the recess allows the junction member and the fixing element to be properly aligned with one another.

BE2018 / 0090

-4 predetermined geometry, a first of said retaining members being formed by at least a first segment of the second wire lying at one end of the second wire and forming an angle with the part of the second wire preceding this segment. The presence at the end of one end of the second wire of a first segment which forms an angle makes it possible to produce in a simple and reliable manner a first retaining member. The use of a folded wire makes it possible to obtain, thanks to its geometry, not only a good connection between the first and the second wall, but also a good distribution of the stress exerted on the second wall.

A sixth preferred embodiment of a connecting clip according to the invention is characterized in that the second geometry comprises a second U-shaped segment and a third and fourth segment each time forming the junction between the second and first segment, the second segment forming an angle between 80 ° and 100 °, in particular 90 °, with the third and the fourth segment. The second segment can thus be used to connect the anchoring element to the junction member.

In the drawings, the same reference has been assigned to the same element or to an analogous element.

FIG. 1 illustrates using a first embodiment the connecting clip 10, according to the invention. This connecting clip crosses a recess 11 between a first 1 and a second 2 wall. In the majority of building constructions, the first wall 1 is a wall constructed, for example from blocks or concrete slabs, and forms the load-bearing wall of the construction. The second wall 2 is the facing wall constructed using building elements such as, for example, masonry bricks. The recess 11 left between the first and the second wall forms a ventilation space 11, called a ventilated vacuum, in which a thermal insulator is preferably applied, for example formed by a layer 3 of insulating material, such as for example polyurethane or polystyrene, to insulate the building and reduce heat loss. This layer 3 is applied against the face of the first wall 1 facing this recess 11. This thermal insulator partially fills this recess thus leaving space in which air can circulate.

The thermal insulation is held against the first wall using a dowel 5, which preferably is provided with a disc 7, which dowel is introduced into a cavity 4, which preferably is obtained by drilling in the face. from the first wall facing the second wall. When the plug is inserted into the cavity and the insulating layer 3 is placed against the first wall, the disc 7 keeps the thermal insulator in place against the first wall.

The pin 5 placed in the cavity 4 is also used to introduce a fixing element 6 which is part of the connecting clip according to the invention. The connecting clip also includes an anchoring element 8 having at least one retaining member 12 arranged to be secured to the construction element on which it will be applied. This retaining member will thus help to maintain the second wall in position during its construction and cooperate with the fixing element,

BE2018 / 0090

-10the connecting member and the anchoring element in order to transfer to the first wall a mechanical stress to which the second wall would be subjected after its construction. The at least one retaining member 12 is, in this embodiment, curved or can be curved by folding so as to be folded towards and / or against the second wall 2 during its application and thus establishing a connection with the second wall when applied. The fixing element 6 and anchoring element 8 are connectable by a joining member 9 allowing height adjustment and alignment between them. In the embodiment illustrated in FIG. 1, this height adjustment and the alignment are obtained by sliding the anchoring element in height relative to the fixing element on the junction member. Alignment means the possibility of being able to align the anchoring element with respect to the axis along which the fixing element extends in the first wall.

Figures 2 a to e and Figure 3a together show a first embodiment of a connecting clip according to the invention. Figures 2 a to d show that according to this first embodiment the anchoring element 8 is formed by a first wire 8a, 8b, 8c or 8d folded according to a first predetermined geometry. The first geometry is formed by a first 14-1 and a second 14-2 leg, each provided with a foot 15-1, 15-2. The feet form the retaining members. In the embodiments shown in Figures 2a to c the legs are interconnected by a section formed by a loop 16 in the form of an eyelet. The loop 16 in the form of an eyelet forms an opening in which the joining member 9 can engage. In the embodiment shown in FIG. 2d, the legs are connected together by a section formed by a flattened part 16 ’provided with an opening formed by a perforation 16 ″ of the first wire from which the connecting fastener is made. In the embodiment shown in FIG. 2e, the connecting clip comprises only a single leg 14-1 and a single foot 15-1. Leg 14-1 begins with a loop section 16 in the shape of an eyelet

BE2018 / 0090

-11 Instead of using a loop 16 in the form of an eyelet for the embodiment with one leg, it is also possible to use a section with a flattened part similar to that shown in FIG. 2d.

The fixing element 6, see FIG. 3, is formed by a rod having a threaded or twisted part 6-1 and the joining member 9 is formed by a nozzle 17 provided on a head of the rod and forming a hook. The latter is dimensioned in such a way that the loop 16 in the form of an eyelet, or the 16 ”perforation, can be engaged around the hook. The hook preferably forms a hollow 18 in which the loop in the form of an eyelet, or the flattened part, can be engaged. The fixing element 6 is preferably provided with a plug-shaped protrusion 13 and applied downstream of the recess 18 on the rod. This protuberance is dimensioned in such a way as to conform at least in part to another recess 19 present at the entry of the ankle 5. Thus this protuberance will be housed tightly in this other recess of the ankle and will considerably reduce the penetration of water and air in the ankle. Preferably this protrusion is made of plastic, for example by molding, which allows easy and inexpensive manufacture. Preferably, this molding of the plastic material will extend over a part of the fixing element and on the joining member. Instead of using a protrusion, it is also possible to use a washer in the form of a washer, for example made of rubber like those used in plumbing, which would be slid over the fixing element up to the height of the connection between the end piece 17 and the rod.

Preferably the diameter of the opening in the loop in the form of an eyelet is slightly smaller than that of the end piece 17, in order to allow the loop 16 to be well tightened on the end piece when it is mounted on it. Preferably the first wire with a diameter between 1.5 and 3 mm, in particular 2.2 mm, which allows it to keep enough rigidity while remaining thin enough for walls with a thin horizontal joint and to easily bend it . When using a wire

BE2018 / 0090

-12 having a flattened part with a perforation 16, the latter will have a diameter slightly greater than that of the end piece 17. To make up for this slight difference it will suffice to provide that the joining member 9 can be slightly inclined towards the first wall.

The end piece 17 of the fixing element 6 preferably has a hollow shape, for example in J, to facilitate the alignment of the anchoring element on the axis of the rod of the fixing element 6 The hollow may have rounded or substantially rectangular internal sides.

FIG. 3b illustrates another embodiment of the fixing element 6 and of the anchoring element 8. This embodiment differs from that illustrated in FIGS. 2 and 3a by the fact that the junction member 9 , formed by a tip 17, is taken up on the anchoring element instead of on the fixing element. The latter has a flattened head 6-2 provided with a perforation in which the end piece 17 engages. The height adjustment and alignment is done in a similar manner by sliding the junction member in the present perforation. in the flattened head 6-2.

Figures 3c and 3d illustrate other embodiments of the fastening element 6 and the junction member 9. In these embodiments the junction member has the form of a podium used for example in bicycle races or car or motorcycle competition. The lower steps of this podium have a perforation 71-1 and 71-2 which crosses the step from top to bottom and is located substantially in the center of the step. The central step is provided with a cavity 77 arranged in a rising wall and arranged to receive the head 6-2 of the fixing element. The fixing element 6 is mounted on the junction member by introducing the head 6-2 of the rod into the cavity 77. In the embodiment shown in FIG. 3c, the head 6-2 has a threaded part, whereas in the embodiment shown in Figure 3d, it is a nail head shape. In the perforations 71-1 and 71-2 of the steps on either side of the central step we can then

BE2018 / 0090

-13insert a wire comprising a leg and a foot as well as a curved part which is engaged in these perforations. Height adjustment and alignment is done by sliding the wire in the perforations 71-1 and 71-2. In the embodiment shown in Figure 3d the sliding of the head 6-2 in the cavity 77 can also contribute to the height adjustment and alignment.

FIG. 3e illustrates a variant of the embodiment shown in FIG. 3c which makes it possible to introduce two anchoring elements 8-1 and 8-2 in the junction member. This makes it possible to better distribute the load exerted on the second wall and thus to reduce the diameter of the wires used. As in Figure 3b the shape of the junction member, formed by a tip 17, allows height adjustment and alignment. The use of a junction member 9, as illustrated in FIG. 3e, and which is provided with perforations 71-1 and 71-2 which cross the steps makes it possible to introduce the anchoring element therein, either from above or from below or rotate the joint, which increases the range for height adjustment and alignment.

The fastening element 6 is preferably made of metal, in particular stainless steel, and the anchoring element 8 is preferably also made of metal, in particular stainless steel. The joining member 9, formed by the end piece 17, is for example covered with a plastic material, such as for example nylon or polypropylene, on the metal of the fixing element. Preferably, this same plastic material is also applied to a part of the fixing element in extension of the end piece. In this way the plastic prevents direct contact between the fixing element and the anchoring element, which if they are made of different metals makes it possible to avoid a chemical reaction between these metals. Of course the junction member can be covered by molding or by applying a sheath, or a plastic or rubber tube, around this head of the rod.

BE2018 / 0090

-14In the embodiment shown in Figure 2a, d and e, the retaining member formed by the feet 15 is straight while in that shown in Figure 2b it is wavy. In the embodiment shown in FIG. 2c, the retaining member is also rectilinear, but it also has a curved end which forms an angle of 90 ° with the rectilinear part. In the embodiment illustrated in Figure 2a, d and e the feet 15-1 and 15-2 can be bent by folding the material from which they are made.

To apply the connection clip according to the invention, use is preferably made of a series of tools developed for this purpose. However, it should be noted that these tools will facilitate the installation of the connection clips, but that they are not essential for this installation. FIG. 43 illustrates a tool 100 for positioning the holes to be drilled in the insulation layer and the first wall to introduce the dowel into which the fixing element will be applied. The positioning tool is formed by two slats 101 and 102 forming a right angle between them. The first slat 101 is provided with a set of holes 103 passing through this first slat. The holes are placed at different heights which correspond to a multiple of the sum of the height of the building elements and the height of the joints between the building elements of the second wall. In the example shown in Figure 43 this sum of heights is 40, 45 or 50 mm. The second slat 102 is used to be placed on the second wall under construction, because it is the height reached by the second wall under construction which will help to determine the height at which it will be necessary to drill the cavities 4 in the first wall and the insulating. In use, the mason will deposit the second batten on the second wall under construction. After that he will be able to mark the places where it is necessary to drill by making use of the whole of the line of holes 103 chosen according to the construction elements and the horizontal joints used for the second wall and taken up on the first batten.

BE2018 / 0090

FIG. 44 illustrates a drilling aid tool which is formed for example by a block 104 drilled with another hole 105 whose axis is perpendicular to the face of the block which will be applied to the insulation. Preferably this block will be cube-shaped, but it goes without saying that other geometric shapes can be used, such as a cylinder. This block when it is placed against the layer 3 of insulating material makes it possible to guide the drilling so that it is perpendicular to the first wall and to the layer of insulating material. The drill bit will be slid into the other hole 105 of the block to then drill the hole (s) at the locations that have been indicated using the positioning tool 100. Passing the drill bit to through the other hole 105 this wick will be guided by the linearity of the other hole 105 and it will be possible to obtain a cavity 4 perpendicular to the wall of the first wall and the insulating layer. The fact that the cavity is perpendicular has the advantage that the fixing element 6 will then extend perpendicularly in the first wall and that therefore the transfer of force by the connecting clip will be optimized.

Figures 45 and 46 illustrate a screwdriver bit 106 arranged to be mounted on a head of a screwdriver / drill and take hold on the connecting member. The screwdriver bit comprises a transmission shaft 107, one end of which is arranged to be introduced into the head of the screwdriver / drill and the other end is provided with a coupling piece 108 allowing coupling with the connecting member. In the embodiment according to FIG. 45, the coupling part is formed by a rectangular part provided with a recess which has the dimension of the end piece 17 so as to allow this recess to be engaged in the end piece. In the embodiment according to FIG. 40, the coupling piece 108 is formed by a pad which can take hold in the opening of the C-shaped joining member which will be described below.

BE2018 / 0090

FIG. 47 illustrates a positioning template 109 of other cavities, for example formed by cuts or holes, to be made in the second wall to accommodate the retaining member there. The positioning template is formed by a plate provided with several perforations 110. The plate is also provided with a protuberance 111, itself provided with another perforation 112 whose diameter is slightly greater than that of the end piece 17. The perforations 110 serve to indicate the place where to make another cavity in the second wall.

To apply the connection tie shown in Figures 2a, b and c and 3a, the mason will preferably use the tools shown in Figures 43 to 47. The mason will place the second slat 102 of the positioning tool 100 on the second wall under construction and indicate using holes 103 the place (s) where to drill in the layer of insulating material. Using a drill, and making use of block 104, the mason will make one or more cavity (s) 4 in the first wall 1 and the layer of insulating material 3 to introduce the dowel 5. After the drilling of or cavity (s) 4 and the introduction of the dowel in the cavity 4, we will introduce the fixing element in the dowel by screwing it. To this end, it will use the screwing bit 106 which it will couple to the bit 17. The rotation imposed by the drill on the shaft 106 (indicated by the arrow 113 in FIG. 45 and 46 will be transmitted by the part 108 to the end piece 17 housed in its recess, thus the fastening element can easily and quickly be inserted into the dowel.

Then, and in the case where the construction elements of the second wall are not already provided with other cavities to apply the retaining member, the mason will take the positioning template 109 which he will hang using the other perforation 112 on the end piece 17. Then he will place the positioning template 109 on the second wall under construction to apply there using the perforations 110 one or more marks to indicate the places where one or others (s )

BE2018 / 0090

-17 cavity (ies) must / must be carried out. After that he will make these other cavities in the building element of the second wall.

Then the mason will put binder, such as mortar or glue, on the second wall under construction and will then take the anchor element and apply pressure on the legs 14-1 and 14-2 by pushing them. towards each other. This will have the consequence that the eyelet-shaped loop will open a little, which will facilitate the engagement of this loop on the end piece 17. Then it will slide the loop on the end piece so as to adjust in height l anchor relative to the second wall under construction and align the anchor relative to the axis of the fixing element. By height adjustment means that the anchoring element is placed so that the legs 14-1 and 14-2 are at the height of the second wall under construction and embedded in the binder, as illustrated in Figure 1 After the loop has been correctly positioned, the mason will let go of the legs 14-1 and 142 so that the loop 16 can come to tighten on the end piece 17. Preferably the fixing element will be positioned on the first wall of such so that the loop 16 can be housed in the recess 18. In this latter configuration, the anchoring element will be aligned with the fixing element, which allows direct transfer in the axis of the fixing element of the stress applied on the second wall.

Before the anchor is mounted on the joining member and correctly positioned in height and aligned, the mason will have bent feet 15-1 and 15-2 of the embodiment illustrated in Figure 2 (a) . As illustrated in Figure 4 (b) the retainer will be placed on the second wall. The mason will then introduce the folded feet into the other cavities made in the second wall. Figure 4 (b) illustrates the placement of the retainer according to Figure 2 (b). In this embodiment the brick is already provided with another cavity formed by a groove 80 in which the retaining member, formed by the wavy shape of the feet, can be placed by the mason. In the embodiment

BE2018 / 0090

-18illustrated in Figure 4 (c) the brick is provided with another cavity formed by two holes 81-1 and 81-2 in which the curved ends of the feet 15 of the embodiment illustrated in Figure 2 (c) will be introduced.

The fact that the retaining member is introduced into the second wall will result in it being made integral with the construction element in the second wall in which it is placed. So when a stress is applied to the second wall, the retaining member, which is now secured to the second wall, will feel this stress and transmit it via the legs 14-1 and 14-2 to the eyelet 16 and thus towards the fixing element 6. This will result in a transfer of this constraint to the first wall. The connecting clip according to the invention also makes it possible to hold the second wall in place during its construction when the mortar between the bricks has not yet dried. The fact that the retaining member is in the other cavities 81 or 80 has the consequence that it is retained there thus preventing the second wall from moving in the hours which follow its construction, it will remain in this other cavity and the mortar or the glue, which surrounds the anchor, will hardly be removed if the second wall moves. This reduces the likelihood that an air bubble, which could affect stress resistance, will form around the anchor in the mortar or glue until it has hardened.

FIG. 5 illustrates another embodiment of the junction member 9. In this embodiment the junction member has the form of a podium used for example in bicycle races or in car or motorcycle competition. Each step of this podium has a perforation 24 which crosses the step from top to bottom and is located substantially in the center of the step. The central step is provided with a channel 25 into which opens the perforation applied in this central step. The junction member is mounted on the fastening element 6 by introducing the head of the rod 9 into the channel 25 in such a way

BE2018 / 0090

-19 that it can pass through the perforation 24. In the perforations of the steps on either side of the central step, it is then possible, for example, to introduce a wire comprising a leg and a foot as well as a curved part which is engaged in these perforations.

Figures 6 a, b, c, d and e illustrate a second embodiment of a connecting clip according to the invention. According to this second embodiment, the anchoring element has a second geometry and is mounted in a second part 9-2 which is part of the junction member. Still according to this embodiment, the anchoring element is formed by a second wire 8d bent according to the second predetermined geometry. A first retaining member being formed by at least a first segment 20-1 of the second wire. This first segment is located at one end of the second wire and forms an angle with the part of the second wire preceding this first segment. In the embodiment illustrated in Figure 6, the second wire has two first retaining members, 20-1 and 20-2, each located at one end of the second wire. Preferably, the second geometry also includes a second segment 26 in the shape of a U and a third 22 and fourth 23 segment each forming the junction between the second and first segment. The second segment forming an angle between 80 ° and 100 °, in particular 90 °, with the third and fourth segment. According to a more elementary embodiment, the anchoring element could be formed from only the first segment 20-1, the third segment 22 and the rising part of the second segment 26. The wire is preferably a wire having a diameter located between 1.5 and 3mm, preferably 2.2mm, which makes it compatible with the dimension of so-called thin joints in construction. In addition, this dimension gives it sufficient rigidity and allows it to be easily folded. The anchoring element 8 is, as in the first embodiment, made of metal, preferably steel

BE2018 / 0090

-20 stainless. The same is true for the third and fourth embodiment which will be described below.

The retaining member illustrated in FIGS. 6 and 8 has a geometry and an operation similar to that shown in FIG. 2 (c), but it goes without saying that in this second embodiment, the geometries shown in FIGS. 2 ( a) and (b) can also be used.

As illustrated in FIGS. 7 and 8, the joining member 9 comprises a first part 9-1 having a geometry essentially in the form of a C and the second part 9-2 having a geometry essentially in the form of a T. The second part being dimensioned and retained in the first part so as to slide inside the C-shape, as illustrated in FIG. 8. Preferably the clearance between the first and second part is as small as possible and just enough to allow the one piece slides into the other. This greatly reduces the likelihood that the second part can move relative to the first after the connecting clip has been correctly positioned in height. Indeed, such a displacement could affect the transfer of the load from the second wall to the first wall.

The second part illustrated in FIGS. 6 a to d is provided with at least one perforation 24 which is crossed by the anchoring element 8d. The anchoring element is mounted in such a way that the third 22 and fourth 23 segments pass through the perforations 24 which each end in a channel 25, preferably semi-cylindrical or U-shaped, located in the horizontal branch of the form in T of the second part. Thus the second segment 26 is partly housed in the channel 25. This allows the anchoring element to be properly retained in place in the second part of the junction member. The fact that the second segment forms an angle with the third and fourth segment has the advantage of also retaining the anchoring element well in the second part of the joining member.

BE2018 / 0090

-21 In the embodiment illustrated in Figure 6e the anchoring element 8d is trapped in the second part 9-2. This embodiment is obtained by molding.

When the second part 9-2 is housed in the first part 9-1, the horizontal branch of the T-shape will be inside the C-shape and the vertical branch of the T-shape will cross the opening present in the C shape. The T shape will thus be able to slide inside the C shape which will allow a height adjustment between the anchoring element, the fixing element and the member junction. It being understood that the anchoring element 8d is mounted on the second part 9-2, it can also slide in the first part thanks to the sliding movement of the second part relative to the first. Thus by sliding the second part into the first, the anchor element will be displaced in height, which makes it possible to adjust the height of the anchor element relative to the second wall.

Figure 7 illustrates the fastener 6 applied to the back of the first part 9-1. Thus the junction member 9 makes it possible to slide the anchoring element relative to the fixing element. The connecting member is preferably made of plastic to reduce the thermal bridge to the first wall. The fact that the anchoring element is retained in the second part, which is preferably made of plastic and that the first part is also preferably made of plastic, will prevent the different metals from which the element is made. anchoring and fixing are in direct contact with each other thus avoiding heat losses and chemical reactions.

On the back of the first part 9-1 there is also the protrusion 13 in the form of a plug, which has the same function as that presented in the first embodiment. Of course one could in this embodiment use a washer in the form of a washer, as for the embodiment shown in FIG. 3a.

BE2018 / 0090

-22To apply the connecting clip according to the second embodiment, apply the dowel and the fixing element provided with the first part 9-1 in the same way as that described for the application of the connecting clip according to the first embodiment. However, screwing bit 106 illustrated in FIG. 46 will be used to screw the fixing element provided with the first part 9-1 into the dowel. We will also use a positioning template whose protuberance 111 will have a geometry adapted to the C shape of the first part 9-

1. After having marked and made the other cavities in the element of the second wall under construction, we will slide the second part 9-2 provided with the anchoring element 8 into the first part. The sliding of the second part with respect to the first will make it possible to align the anchoring element with respect to the height of the second wall 2 under construction. The mason will take the curved ends of the first retaining members 20-1 and 20-2 in order to introduce them into the other cavities 81, in a similar manner to that described in FIG. 4c. Thus the retaining member can retain the second wall. The presence of the retaining member will help to keep the second wall in position during its construction and cooperate with the anchoring element and the fixing element in order to transfer to the first wall a mechanical stress to which the second wall after being built.

Figures 9 a and b show a third embodiment of a connecting clip according to the invention. According to this embodiment, the anchoring element is formed by a third wire 8e folded according to a third predetermined geometry. A first of said retaining members being formed by at least a first segment 30-1, 30-2, of the third wire lying at the level of one end of the third wire and forming an angle with the part 31-1, 31-2 , of the third thread preceding this segment. The segments 30-1 and 30-2, as well as the parts 31-1 and 312 have a geometry and a function similar to that of the anchoring element illustrated in FIG. 2c. The first segments being provided with

BE2018 / 0090

23 curved parts similar to those illustrated in FIG. 2 (c). A second of said retaining members being formed by a U-shaped intermediate segment 32 of the third wire. This second retaining member being connected to parts 31-1 and 31-2. This second retaining member extends into the opening formed by the joining member 9. Preferably the third wire with a diameter between 1.5 and 3 mm similar to that of the first and second wire.

Still according to this third embodiment, the junction member is preferably formed by a third part 33 having a U-shaped profile. The rising sides of the U-shaped profile are each provided with a passage 34 crossing the rising side and s' extending over at least 50% of the height of the rising sides.

The anchoring element being mounted in this junction member so as to pass through the corridors 34. Thus it will be able to slide in height inside these corridors to adjust the height between the anchoring element and the fastening element. The connection between the parts 31-1 and 31-2 and the second retaining member are each in one of the respective corridors. Their displacement in height inside the corridors allows an adjustment in height of the anchoring element. In this embodiment, the back of the junction member will preferably be configured in a similar manner to that illustrated in FIG. 7 and therefore provided with a protrusion 13.

To apply the connecting clip according to the third embodiment, the dowel and the connecting clip will be applied in the same way as that described for the application of the connecting clip according to the second embodiment. After mounting the link, the mason will adjust the anchor to the height of the second wall under construction by sliding it into the channel 34. After adjusting the height of the anchor he will introduce the curved part of segments 30-1 and 30-2 in the second wall in a similar way to that illustrated in Figure 4c. If necessary, it will also position the

BE2018 / 0090

-24 intermediate segment 32 in U so that it comes to push against the internal face of the second wall. Thus in this third embodiment the anchoring element will exert a retaining force in two different places from the construction element of the second wall.

Figures 10a and b show a fourth embodiment of a connecting clip according to the invention. According to this embodiment, the anchoring element is formed by a fourth wire 8f bent according to a fourth predetermined geometry having a profile in the form of two T connected by their base. This profile comprises a first T having a first vertical part 40 and a first horizontal part 41 extending above this vertical part. The first horizontal part 41 forming the retaining member. The second T of this profile in the form of two T comprises a second horizontal part 42 and a second vertical part 44, which joins the first vertical part 40 of the first T. This second horizontal part 42 is mainly housed in the junction member. The latter is preferably formed by a fourth part 43 having a C-shaped geometry, as illustrated in FIG. 10b. The second horizontal part 42 of the second T being mounted in this fourth part 43 so as to slide inside the C-shape. The second vertical part 44 of the second T crosses the opening of the C-shape to reach the first vertical part of the first T. The back of this junction member is produced in a similar manner to that illustrated in FIG. 7. Preferably the fourth wire has a diameter between 1.5 and 3 mm, similar to the other embodiments already described.

To apply the connecting clip according to the fourth embodiment, the dowel and the connecting clip will be applied in the same way as that described for the application of the connecting clip according to the second embodiment. After mounting the fixing element and the joining member, the mason will introduce the second horizontal part 42 of the second T into the joining member 43 and will adjust

BE2018 / 0090

-25the anchoring element at the height of the second wall under construction by sliding it in the fourth part 43. During the height adjustment it will introduce the curved parts of the segments 41-1 and 41-2 in the second wall in the same way as that described for the third embodiment.

Figures 11 to 19 illustrate a fifth embodiment of a connecting clip according to the invention where the anchoring element is formed by a plate 50 which can be mounted on or in the junction member 9. The plate comprises a head 51. In the embodiment illustrated in FIGS. 11, 13 and 15 to 19, the head 51 of the plate has a hole 52 in which a junction member 9 similar to that illustrated in FIG. 3a can engage. In the embodiment illustrated in FIG. 13, the hole is extended, preferably by a ring 53, to increase the contact surface between the head of the wafer and the junction member and thus improve the connection between the wafer and the fixing element. This also makes it possible to avoid damaging the plastic coating of the end piece 17. When using a plate with a hole 52, the latter will have a diameter slightly greater than that of the end piece 17. To catch up this slight difference in diameter it will suffice to provide that either the connecting member 9 can be slightly inclined towards the first wall, or the head of the wafer.

The head 51 of the wafer, in the embodiment illustrated in FIGS. 12 and 14, is T-shaped and is dimensioned in such a way that it can slide inside the junction member 9 formed by a fifth piece in the form of C and illustrated in FIG. 20 and which is similar to that illustrated in FIG. 7. This joining member is similar to that illustrated in FIG. 7 but is distinguished by cheeks 29-1 and 29- 2 of the thicker C shape and a narrower opening. The head of the wafer will be slid into the opening of this C shape and can slide there. The horizontal part of the T-shape being engaged at

BE2018 / 0090

The interior of the C shape of the junction member and the vertical part of the T shape extends through the opening of the C shape. Preferably the plate has a thickness of 0.7 to 1.5mm, preferably 1mm, and is made of metal, especially stainless steel. Such a thickness gives it sufficient rigidity while making it easy to fold the retaining member.

In this fifth embodiment, said at least one retaining member is formed by at least one first tongue 54-1, 54-2 applied in the plate at the bottom thereof to the face opposite to that of the head 51. This first of said at least one tab extends along a fraction of a lateral edge 55-1, 55-2 of the wafer and is obtained by cutting in the bottom of the wafer. This cut in the insert ensures that the tab is foldable. A second 56 of said at least one tab extends into a first opening 57 applied in the wafer. This first opening is located offset from the first tabs towards the head of the wafer. If necessary, the plate is provided with reinforcing ribs (not shown in the drawings) applied at the height of the head part.

Still according to this fifth embodiment, said at least one retaining member also comprises at least one third tab 58-1, 58-2 applied in the plate halfway up the lateral edges 55-1, 55-2 of the plate. and is also obtained by cutting in the wafer. Preferably at least one second opening 59 is provided in the plate 50 in order to increase the retention of the facing wall and the resistance to tearing. The first and the second opening, which extend in parallel to each other, are separated by a crosspiece 60. It is also possible to apply a fourth tongue 61-1, 61-2 as a member. of restraint. These fourth tabs are located at the height of the head of the wafer and are also obtained by cutting in the

BE2018 / 0090

-27plate. It goes without saying that the presence of tabs in four different places is not essential for carrying out the invention and that it suffices to have a single tab. The multiplication of the tabs has the advantage of providing an anchoring element which can be used for different dimensions and models of the building element of the second wall.

The embodiment illustrated in FIG. 11b differs from that of FIG. 11a by a more elementary embodiment which only comprises a second tongue 56 placed in the first opening 57 in protrusion of the cross-member 60. The embodiment illustrated in Figure 11c differs from that of Figure 11b by a longer head. The length of the head will be mainly determined by the width of the building element used for the second wall.

The anchoring element 50 illustrated in FIG. 15a has an L shape. The hole 52 is applied to the upper part of the vertical branch of the L shape and the first tongue 54 is located at the bottom of the vertical branch of the L-shape. This first tongue 54 is obtained by cutting out the L-shape from the horizontal branch of the L-shape.

FIG. 15b shows an anchoring element 50 which differs from that shown in FIG. 15a by the presence of a stair step at head height 51. The hole 52 is present on the top of the step. In this embodiment the fixing element 6 is provided with a joining member 9 formed by a simple hook. The step aligns the fastener and the anchor between them.

In the embodiments shown in Figures 15c and 15d we see the same hook as that shown in Figure 15b but this time with an anchoring element 8 formed by a wire provided with a loop 16, respectively with a flattened part 16 'provided with a hole. The difference in height 120 between the anchoring element and its point of attachment to the fixing element that allows the presence of the step in the figure

BE2018 / 0090

-2815b is in the forms shown in Figures 15c and d obtained by a curvature of the anchoring element which also allows alignment.

The embodiment of the anchoring element illustrated in FIG. 16 differs from that of FIG. 11b by circular openings 57 and 59 instead of rectangular, as well as by the absence of a head 51. The hole 52 being applied in the upper part of the plate of which the anchoring element is made.

The anchoring element 50 illustrated in FIG. 17 has a double sawtooth shape 64-1, 64-2, 64-3 and 64-T, 64-2 ’, 64-3’. A head 51 provided with a hole 52 is connected to teeth 64-3 and 64-3 ’forming one end of the sawtooth shape. The first tongue 54 being applied to the other end of the sawtooth shape where the teeth 64-1 and 64-1 ’are located. This sawtooth shape offers the advantage of allowing the mortar or glue used for the construction of the second wall to be housed between the teeth, thereby better retaining the anchoring element. Preferably at least one of the teeth 64-1, 64-1 ’, 64-2 or 64-2’ is provided with a flap 63, 65 which extends substantially perpendicular to the surface of the teeth. In the illustrated embodiment, the flap extends in a direction opposite to that in which the tongue 54 will extend when it is placed in the second wall. It is however also possible to have an embodiment where the flap and the tongue extend in the same direction. The bib will extend into the mortar or glue when it is placed with the anchor in the second wall, thereby increasing the tear resistance of the anchor. This or these flap (s) is or are in particular useful (s) for second walls are in fine joints. In the latter case, it is necessary to use anchoring elements of small thickness, for example 1 mm, because otherwise their integration into the thin joint poses a problem. A flap with a height of 0.5 to 0.8 mm can locally provide a higher thickness and therefore better anchoring, without disturbing the thin joint. This

BE2018 / 0090

- 29 better anchoring will indeed slow down the sliding of the anchoring element in the mortar or glue.

The anchoring element 50 illustrated in FIG. 18 has a T-shape, the horizontal branch of which also has flaps 65. The vertical branch of the T-shape has at its lower end the head 51 provided with a hole 52. The flaps are preferably applied to the lower flank of the horizontal branch and have the same function as that described for the embodiment shown in FIG. 17.

The anchoring element 50 illustrated in FIG. 19 has a double T shape, the horizontal branches of which also have at least one of the flaps 63 and 65. The first 54 and second 56 tabs are applied on either side of the vertical branch of the upper T-shape.

FIG. 21 illustrates a variant of the fifth embodiment. In this latter embodiment, the plate 50 comprises a head portion 51 having an L-shaped profile. The junction member 9 being formed by a first part 9-1 illustrated in FIG. 20 and having a geometry essentially in the form of C, similar to that illustrated in FIG. 7. The joining member also comprises a second part 9-2 having a T-shaped geometry, similar to that illustrated in FIG. 8, except that it comprises a slot 62 instead of the perforations 17. If necessary, the second part and the anchoring element can also be produced by molding by molding the second part on the L-profile. The second part being mounted in the first part so as to slide inside the C shape. The slot is crossed by the L-profile of the head part of the insert. The L-shaped profile is mounted in such a way in the second part that the foot is anchored in the slot 62 and passes through the second part. Preferably the plate and the second part are molded together from

BE2018 / 0090

-30 such that the plate is firmly anchored in this second part.

FIG. 22 illustrates a sixth embodiment of a connecting clip according to the invention. This sixth form is distinguished from the fifth embodiment by the presence of at least one lateral extension 70-1 and 70-2 to the side walls of the first part 9-1 of the junction member. In this embodiment this or these lateral extension (s) is / are formed by angular ridges which preferably extend at an angle of 45 ° on either side of the first part 9 -1. These lateral extensions are each provided with two cavities 71-1 and 71-2 applied at a distance from each other. These cavities are used to introduce an additional anchoring element 73, as illustrated in FIGS. 25, 26 and 27. These additional anchoring elements have a geometry and a function similar to that illustrated in FIG. 2 or 6. A leg 74 , or both legs, of this additional anchoring element will come, or will come, to be inserted into one of the cavities 71-1 or 71-2.

Figure 23, respectively 24, illustrates a variant of this sixth embodiment where the lateral extensions 70-1 and 70-2 are in the form of a staircase applied on either side of the first part 9-1, respectively in the form of a wing 76-1 and 76-2 applied on either side of the first part 9-1. Both the stairs 75 and the wings 76 are provided with cavities 71. If necessary, the embodiment illustrated in FIG. 20 could also be provided with lateral extensions. The embodiment illustrated in FIG. 24 allows, if the upper face of the lateral extensions is in the axis of the fixing element, to vary the height of the point of attachment of the anchoring element, if rotates the fastening element and therefore the joining member by half a turn. This difference in height is equivalent to the height of the side extension.

BE2018 / 0090

FIG. 28 illustrates the application of this fifth embodiment of the connecting clip according to the invention and making use of the plate 50 illustrated in FIG. 11. The placement of the pin 5 and the element of fixing 6 is similar to that described for the first embodiment because the plate is mounted on the hook of the joining member 9 in a similar manner to that where the first wire is applied. The same goes for the application of holes 81 in the building element of the second wall. After having adjusted the height of the plate relative to the second wall 2 under construction, the mason will bend one or more of the retaining members to place them against and / or in the second wall. For example, the first tabs 54-1 and 54-2 will be folded and introduced into the holes 81-1 and 81-2 applied in the second wall to penetrate the latter. The second tab 56 will be folded to be applied in the hole 81-3. Where appropriate, the third tabs 58 and the fourth tabs 61 can, either in combination with the first and second tabs, or alone, be folded and applied in other holes applied in the second wall, respectively against the internal face of the second wall. as illustrated in Figure 30. The presence of several tabs on the plate thus allows the same plate to be used for different dimensions of the construction elements of the second wall.

FIG. 29 also illustrates the application of this fifth embodiment of the connecting clip according to the invention but makes use of the plate 50 illustrated in FIG. 14. In this embodiment, the height adjustment is made by sliding the head of the plate in the C-shaped joining element. The application of the tongues is similar to that described above for FIG. 28. FIG. 30 shows the tongues bent and inserted into the holes 81 applied in the second wall and against it.

Figure 31 illustrates the application of the sixth embodiment of the connecting clip according to the invention and making use of the plate

BE2018 / 0090

-3250 illustrated in Figure 12 in combination with the additional anchoring elements shown in Figure 25. We can see not only the plate 50 whose head is inserted into the junction member 9, but also the additional elements of anchoring 73 which are introduced into the cavity 71 provided in the ridges 70 of the junction member illustrated in FIG. 22. The plate 50 is laid in the same way as that described in FIGS. 29 and 30. The additional anchoring elements 73 are introduced into additional cavities 81 ′ of the second wall and the plate is applied in the same way as that described in FIG. 30. FIG. 32 illustrates the use of only the additional anchoring elements 73 without making use of the brochure. It is in fact possible to use the sixth embodiment by making only use of the additional anchoring elements 73 whose end 74 is introduced into the cavity 71-2 of the lateral extension 70-1. In FIG. 31, it can therefore be seen that not only the plate 50 serves as an anchoring element but also the additional anchoring elements 73 applied in the cavities 71 of the ridges which are part of the joining member. Thus we increase the number of anchor points of restraint and we distribute more the stress that would be applied on the second wall. As both the anchoring element and the additional anchoring element are connected to the fixing element via the junction member, the stress will be transferred to this fixing element and thus to the first wall .

It will be clear that, even if the various embodiments of the connecting clip according to the invention have been described separately, the invention is not limited to the embodiments described and that it is possible to combine shapes particular embodiments of the junction member with particular shapes of the anchoring element, provided of course that the selected embodiments allow the junction member to be linked with the anchoring element. he is also

BE2018 / 0090

-33possible to apply embodiments of the retainer on other embodiments of the anchor.

Figure 33a shows another variant of the fifth embodiment where the head of the wafer 50 is formed of two arms 86-1 and 86-2 stretched towards one another. Figure 33b shows the first part 9-1 of the junction member adapted to the two arms of the head shown in Figure 33a. This first part is formed by two T connected by their base so as to form two passages 87-1 and 87-2 in which the arms 86-1 and 86-2 can respectively engage. FIG. 33c shows another embodiment of the first part 9-1 of the junction member adapted to the two arms of the head shown in FIG. 33a. According to this other embodiment, the first part is formed from a C 88 profile in which a T profile 89 is introduced so as to form two L-shaped passages on either side of the T shape. arms 86-1 and 86-2 of the head of the wafer will then be engaged in these L-shaped passages.

Figure 34 shows the fastening element according to a seventh embodiment of the connecting clip according to the invention. This shape is distinguished from the first embodiment by the presence of a sole 90 located under the protrusion 13. This sole extends on either side of this protuberance, which is preferably provided with a flattened part for allow a larger contact surface between the protuberance and the sole. The latter will slip into the thermal insulating layer 3, as illustrated in FIG. 35. The sole is located just behind the disc 7.

The junction member 9 is formed by the end piece 17, similar to that illustrated in FIG. 3, and a shim 91 of thickness also illustrated in FIG. 36. Just as in the first embodiment, the end piece 17 is provided on the head of the rod. The shim 91 is formed by a rectangular patch provided with yet another hole 92. This hole 92 is not centered on the patch, but offset with respect to the center of the latter.

BE2018 / 0090

-34 both in height and in width. Thus by rotating the pellet when it is placed in the hook formed by the end piece 17, a variation in height of the space available inside the recess 18 is obtained.

Still according to this seventh embodiment, the anchoring element is formed by a grid 93 made of horizontal and vertical wires, as shown in FIG. 37. Preferably the horizontal wire has a diameter of 4mm the vertical wire has a diameter of 5mm , which gives a low weight to the grid and allows little stress on the fastening elements. The grid is attached to the fixing elements, preferably using horizontal wires. Figure 37 shows that a limited number of horizontal wires of the grid are laid on the shims 91 which are placed in the hook. It is indeed not necessary that each of the horizontal wires rest on a hook. By rotating the shim in the hollow 18, the height of the grid 93 can be adjusted. It is also possible, instead of using a grid, to use for example a perforated plate.

The second wall is formed by building elements which are facing elements, such as for example plates 94 illustrated in FIG. 38. The retaining member is formed by a set of mechanisms 95. Each facing element will be provided with 'at least one of the mechanisms 95 which will be applied to the rear of this facing element 94. The mechanism is dimensioned in such a way that it can be hung on the horizontal wires of the grid so as to rest on these horizontal wires.

To mount the seventh embodiment, the fixing element will be mounted in a similar manner to that described for the first embodiment. However, care should be taken to ensure that the sole 90 is properly inserted into the layer of thermal insulation, that is to say that it extends horizontally. Then we will put the shim 91 in the hook formed by the junction member. When enough fixing elements are placed on the first wall, grid 93 will be

BE2018 / 0090

-35 hung by placing it on the shims 91. The height of the grid will be adjusted by rotating the shims in the hook. After installing the grid, the facing elements 94 will be hooked to the grid using their mechanism 95.

A horizontal stress applied to the facing elements forming the second wall will then be transferred to the first wall through the grid. The sole 90 is used to distribute the vertical stress imposed by the weight of the facing over a larger laying surface on the insulation layer and thus reduce the probability that the fastening element is pulled down by the applied stress.

Figures 39 to 41 show a particular embodiment of the mechanism 95. The latter consists of a first 95-1 and a second component 95-2 which can slide one into the other. The first component 95-1 comprises a first base portion 96 from which extends a protrusion 97 in the form of a dovetail. The second component 95-2 comprises a second base part 98 in which extends another hollow in the form of a dovetail sized to allow the sliding of the first component and the second component therebetween. On the back of this second component are two L-shaped profiles 99-1 and 99-2 which are used to hang the facing element on the grid. These two L-profiles extend lengthwise of this second component and are placed at a distance from each other and oriented in the same direction.

In use, the second component will therefore be hung using the L-shaped profiles on the grid, as illustrated in FIG. 42. The sliding between them of the first and of the second component will make it possible to prevent the vertical wires of the grid and / or the junction member prevents the attachment of the second component, and therefore of the facing element 94, to the grid. Indeed when the L-shaped profiles are at the height of a vertical wire and / or the fixing element, it will suffice to slide the

BE2018 / 0090

-36second component relative to the first to separate it from this vertical wire and / or the joining member.

It goes without saying that the present invention is not limited to the use of the particular mechanism illustrated in FIGS. 39 to 41 and that other 5 mechanisms allowing sliding between the first and the second component can also be used.

For facing elements having a height greater than cm, several mechanisms can be applied to the rear of these facing elements and distributed over the height in order to distribute the weight 10 of the facing element over several horizontal wires of the grid. In addition when the facing wall is built, the facing elements will be automatically locked in place by the very superposition of these elements. To detach a facing element attached to the grid, it will necessarily be necessary to lift several which are superimposed on the one to be detached.
