Description

Description Title of the invention: Hydraulic connection device positioning system and corresponding method technical field

[0001] The present invention relates to the building sector, particularly residential construction (hotels, public access buildings, hospitals). The invention specifically relates to a positioning system for a hydraulic connection device, also known as a sealing kit. The invention also relates to a method for positioning a hydraulic connection device, such as a set of pre-installed hydraulic fittings, the method being implemented using such a positioning system. Technological background

[0002] The construction of walls between two formwork panels is a well-known practice in the building industry. This method involves pouring concrete between two formwork panels to create, or after drying, solid and structurally sound walls.

[0003] For example, when installing a faucet on a concrete wall during building construction, it is customary to first pour the wall between two formwork panels, then excavate a vertical trench in the wall to create the necessary space for the supply pipes and the components, called plumbing connections, intended to receive the future wall-mounted faucet. This trench must then be backfilled, taking care to properly seal all the embedded connections while restoring the wall's strength, sound insulation, and flatness.

[0004] This method, while common, is not entirely satisfactory due to the need for chipping away at the newly constructed wall and the subsequent sealing operations required to fix the supply pipes and the temporary hydraulic fittings before the faucets can be installed. Indeed, this necessitates several complex and time-consuming interventions requiring expertise from various trades.

[0005] The number of interventions, the waste of labor, materials, handling, transport, supplies and logistics make such an implementation obsolete.

[0006] There is therefore a need for a simple, quick, and efficient method and system for installing hydraulic connection devices, such as wall-mounted tap fittings, in reinforced concrete walls. This need exists in various hydraulic fields, including plumbing, heating, and air conditioning.

[0007] The present invention aims to address, at least in part, one or more of the problems described above. Summary of the invention

[0008] A system for positioning a hydraulic connection device is proposed, characterized in that said system comprises: - a supporting body; - a hydraulic connection device comprising two hydraulic inlets and at least one hydraulic outlet, said device having at least one opening face; - at least one magnet, preferably two magnets, allowing the positioning system to be fixed on a metal formwork, said at least one magnet having an application face parallel, and possibly coplanar, to said at least one opening face of the hydraulic connection device, said at least one magnet being preferably removable.

[0009] Thanks to the presence of at least one magnet, this system can be positioned on a metal formwork panel before the installation of another closing metal formwork panel and before the concrete is poured between the two panels. The invention thus allows the hydraulic connection device of the system, for example hydraulic fittings, to be pre-positioned before the wall is constructed, the wall preferably being made of reinforced concrete.

[0010] Advantageously, said at least one magnet has a configuration adapted to prevent rotation of the system when fixed to the formwork. In particular, if said at least one magnet comprises a single magnet, it is possible to provide that the magnet be elongated, preferably rectangular, of a suitable size to prevent the rotation of the system.

[0011] The system allows for easy positioning of the hydraulic connection device in space. This is particularly relevant when the hydraulic connection device includes spare hydraulic fittings. Specifically, the spacing between the spare hydraulic fittings is predefined and maintained by the system body, which, in combination with at least one magnet, enables precise alignment of the spare hydraulic fittings on multiple planes and axes, particularly in depth, as well as horizontally and vertically.

[0012] In the case where the device includes two hydraulic standby fittings, each hydraulic standby fitting includes a hydraulic inlet and a hydraulic outlet. In this case, the hydraulic connection device includes two hydraulic inlets and two hydraulic outlets formed by the hydraulic inlets and outlets of the hydraulic standby fittings. In this case, at least one opening face corresponds to the hydraulic outlet face of each hydraulic standby fitting. The outlet is in fluidic communication with the inlet.

[0013] In cases where the device includes a hydraulic mounting box, said at least one opening face is the opening face of a chamber of the box (with which the hydraulic inlets and each hydraulic outlet communicate) into which a valve body is intended to be inserted. This valve body includes a control element, also called a cartridge, for controlling the flow of fluid between each inlet and each outlet of the mounting box. A valve control system, such as a valve handle, may cooperate with the control element and extend at least partially beyond the opening of the box.

[0014] In cases where the device includes a concealed valve body, also called a concealed valve body, the at least one opening face is the opening face of a chamber within the body (with which the hydraulic inlets and each hydraulic outlet communicate) into which a valve control mechanism is inserted or intended to be inserted. The mechanism may include a control element, also called a cartridge, for controlling the flow of fluid between each inlet. and each outlet of the recessed body. The control unit is designed to cooperate with a control system to be inserted into the hollow body through said opening in the body. The control system includes, for example, an on / off tap handle.

[0015] Where the system includes a concealed hydraulic box or a concealed valve body, the two hydraulic inlets correspond, for example, to a cold water inlet and a hot water inlet, and the at least one hydraulic outlet may correspond to a mixed water outlet, for example, intended to supply, via a pipe, a spout or a shower head. Alternatively, the at least one hydraulic outlet may include a cold water outlet and a hot water outlet. The cold water outlet and the hot water outlet may be connected to pipes intended to be embedded (contained) in the wall (i.e., present during the concrete pouring).These pipes can themselves be connected, before pouring the concrete, to hydraulic waiting connections, for example hydraulic waiting connections of another hydraulic connection device positioning system conforming to the embodiment of the invention and applied against a formwork.

[0016] Once the concrete has been poured, the hydraulic connection device is fixed to the wall by being embedded in the concrete. The operator can access at least one opening face of the hydraulic connection device, advantageously by removing one or more protective elements from the opening face, such as a plug, cover, and / or foam, which are present to prevent the opening from being blocked by the concrete. In particular, when the hydraulic connection device includes pre-installed hydraulic connections, and these pre-installed connections are fixed to the wall, the plumber can connect a tap to the pre-installed connections without having to drill into the wall. The tap could be, for example, a radiator, shower, bathtub, sink, or washing machine tap.

[0017] Said at least one magnet is configured, when applied to a metal formwork panel, to generate a holding force sufficient to counteract at least the weight of the system and the pressure of the concrete when the concrete is poured from the top of the two panels. In other words, said at least one The magnet is configured to generate a holding force preventing movement of the system relative to the formwork, without external intervention.

[0018] The system according to the invention allows, in a single intervention, a rapid, precise and definitive implementation, in the wall, of the supply pipes and the hydraulic connection device (for example, hydraulic waiting fittings intended for a future wall tap).

[0019] Using a magnet has the advantage of allowing the magnet to be reused when it is removable from the system body. Preferably, the magnet or magnets are configured to exert a force of at least 800 Newtons.

[0020] The use of a magnet, thanks to the very strong attraction it exerts on the metal of a formwork panel, allows for a firm and rapid attachment to the panel, without significantly increasing the difficulty of removing the panel after a wall has been built. In building construction, the formwork panels used are predominantly made of metal.

[0021] According to one embodiment, the system comprises, for each magnet, a housing fixed to the support body and in which the magnet is housed, preferably by press-fitting, the housing forming a recess with an opening that is closed by the magnet, the magnet being removable from the housing preferably with a tool. The housing is advantageously made of plastic.

[0022] According to one embodiment, the hydraulic connection device comprises two hydraulic standby fittings fixed to the system body, each hydraulic standby fitting comprising: - a hydraulic inlet intended to be connected to a hydraulic supply line, and - a hydraulic outlet intended to be connected to a hydraulic pipe or a hydraulic fitting, the hydraulic outlets having opening faces (corresponding to said at least one opening face of the device) that are coplanar, preferably protected by one or more protective elements, such as a plug and / or foam. The opening faces of the outlets are intended to be, advantageously via the protective element(s), surface-mounted against one of the formwork panels. According to one embodiment, said at least one magnet has an application face parallel to, and which may be coplanar with, the opening face of each hydraulic fitting. When the hydraulic waiting fittings are arranged on the body opposite said at least one magnet, said at least one magnet has an application face parallel to the opening face of each hydraulic fitting, but said opening faces (of the outlets) of the hydraulic waiting fittings are oriented in the opposite direction to the orientation of the application face of said at least one magnet so that the application face of said at least one magnet applies to one form and the opening faces of the hydraulic waiting fittings are applied, via protective element(s), to the other form.

[0023] In one embodiment, the support body comprises: - a first element, and - a second element, one of the first and second elements carrying the hydraulic connection device, (the other element may be provided with an additional hydraulic connection device, for example additional hydraulic fittings) the first element having at least one portion, which is preferably parallel to, and which is separated from, at least one portion of the second element, the separation being in a direction parallel to the normal to the application face of said at least one magnet (or parallel to the normal to the opening face of each of the two waiting hydraulic fittings when the hydraulic connection device includes waiting hydraulic fittings).

[0024] In one embodiment, the support body includes an adjustment system, preferably by sliding, for the position of the second element relative to the first element, configured to adjust the spacing between the first and second elements. The direction of spacing of the body elements is orthogonal to the longitudinal direction of the system.

[0025] According to one embodiment, the adjustment system for the elements of the support body is a sliding adjustment system which includes: - elements, preferably openings, for positioning adjustment provided in opposite end portions of the second element, - for each magnet receiving housing, an insertion slot, integral with said housing, into which one of said end parts of the second element can be inserted to make one of the adjustment elements cooperate positioning of said end part of the second element with a corresponding element of the insertion housing.

[0026] According to one embodiment, the magnet receiving housing(s) is formed from a single piece, for example made of plastic, with: - the insertion housing at one end of the second element of the support body, - and, when present, the insertion housing at one end of the first element.

[0027] According to one embodiment, the first element of the body is an elongated element, preferably a metal bar, for example flat, each of whose opposite ends is attached to the magnet receiving housing(s), preferably by being inserted into a housing attached to the corresponding housing.

[0028] According to one embodiment, the other of said first and second body elements carries an additional hydraulic connection device.

[0029] According to one embodiment, the hydraulic connection device and the additional hydraulic connection device each comprise two waiting hydraulic connections, each additional waiting hydraulic connection comprising a hydraulic inlet intended to be connected to a hydraulic supply line and a hydraulic outlet intended to be connected (after pouring of the concrete and removal of the formwork) to a hydraulic line or to a hydraulic connection, the outlets having coplanar opening faces with each other, and which are parallel to the coplanar opening faces of the other two waiting hydraulic connections, the outlets of the two additional waiting hydraulic connections being oriented in the opposite direction to the outlets of the two waiting hydraulic connections.

[0030] According to one embodiment, the second element of the body has a U-shaped form, and is preferably formed by a flat metal bar whose end portions are bent at right angles.

[0031] According to one embodiment, the support body has through holes for fixing, for example by rivets, the hydraulic connection device, and possibly an additional hydraulic connection device.

[0032] According to one embodiment, said at least one magnet comprises two magnets separated from each other along a longitudinal direction of the system, the two magnets preferably being located at the longitudinal ends of the system.

[0033] The normal to the application face of said at least one magnet is orthogonal to the longitudinal direction of the system.

[0034] According to one embodiment, to ensure the removable connection between said at least one magnet and the body of the system, said at least one magnet includes a guide piece for a screw, said piece being fixed inside a through passage provided in a body of said at least one magnet, and the body of said at least one magnet having a thread adapted to cooperate with an external thread of the guide piece.

[0035] According to one embodiment, the through passage provided in the body of said at least one magnet is configured to have a thread adapted to cooperate with a thread of a part of a removal instrument of said at least one magnet.

[0036] According to one embodiment, said at least one magnet comprises two removable magnets having coplanar application faces.

[0037] Having two magnets allows for better support of the system on the formwork, limiting in particular the risks of rotation.

[0038] According to one embodiment, the hydraulic connection device comprises: - two hydraulic standby fittings; - a built-in tap body; or - a hydraulic recessed housing for taps.

[0039] According to one embodiment, the system includes an additional hydraulic connection device.

[0040] According to one embodiment, the additional hydraulic connection device comprises: - two hydraulic standby fittings; - a built-in tap body; or - a hydraulic recessed housing for taps.

[0041] It can be foreseen that the hydraulic connection device, for example two spare hydraulic fittings, is different from the additional hydraulic connection device, for example a concealed valve body. It can also be foreseen that the hydraulic connection device includes the same type of element(s) as the additional hydraulic connection device, for example, hydraulic standby fittings.

[0042] In one embodiment, the hydraulic connection device is located, along the depth (or width) direction of the system, on the side of the system opposite at least one magnet. In other words, in this embodiment, the hydraulic connection device is located on the side of a formwork panel, oriented, in particular with at least one opening face oriented, towards that panel, and at least one magnet is located on the opposite side, i.e., with its application face oriented towards the other panel.

[0043] In one embodiment, the hydraulic connection device is located, along the depth (or width) direction of the system, on the same side as at least one magnet. In other words, in this embodiment, the hydraulic connection device and at least one magnet are located on the same side of the system. That is to say, at least one opening face and the application face of at least one magnet are oriented towards the same formwork.

[0044] According to one embodiment, said at least one opening face of the hydraulic connection device has a part located flush with the plane of the application face of said at least one magnet.

[0045] According to one embodiment, the planes of the opening faces of said hydraulic waiting fittings are located flush with the plane of the application face of said at least one temporary fixing element.

[0046] According to a particular aspect, each waiting hydraulic fitting has an opening face (outlet face), preferably with a horizontal (normal) axis, flush with a face of the wall, the (vertical) wall having an opening, i.e. an area devoid of concrete, opposite said opening of the hydraulic fitting.

[0047] According to one embodiment, the system comprises said hydraulic connection device and an additional hydraulic connection device, one of the hydraulic connection devices being located, along the depth (or width) direction of the system, on the side opposite said at least one magnet (said at least one opening face of said hydraulic connection device being oriented in the opposite direction to the application face of said at least one magnet), said at least one opening face of said other hydraulic connection device being oriented in the same direction as the application face of said at least one magnet. It can be provided that said at least one opening face of said other hydraulic connection device is located flush with the plane of the application face of said at least one magnet.

[0048] In general, it can be expected that, after removal of the formwork, said at least one opening face of the hydraulic connection device (and of the additional hydraulic connection device when present), preferably with a horizontal (normal) axis, is located flush with one face of the wall, the (vertical) wall having an opening, i.e. an area without concrete, opposite said opening of the hydraulic connection.

[0049] A method for positioning a hydraulic connection device is also proposed, using a positioning system according to any one of the preceding embodiments, the method comprising the following steps: - possibly, cutting of a metal mesh; - positioning of the system by applying the application face of said at least one magnet of the system against a face of a first metal formwork, and at a location corresponding to a desired position of the hydraulic connection device, said at least one magnet being applied against the inner face of the first formwork, and the hydraulic connection device being located: - either on the side of said at least one magnet, when said at least one opening face of the hydraulic connection device is oriented in the same direction as the application face of said at least one magnet, said at least one opening face being applied preferably by means of protective element(s), such as plug and / or foam, against the first formwork; - either on the opposite side of said at least one magnet when said at least one opening face of the hydraulic connection device is oriented in the opposite direction to the application face of said at least one magnet, - positioning of a second formwork, the inner face of the second formwork being applied against the hydraulic connection device when said at least one opening face of the hydraulic connection device is oriented in the opposite direction to the application face of said at least one magnet; - pouring of concrete between the first formwork and the second formwork; - drying of concrete; - removal of the first formwork and the second formwork, the said hydraulic connection device being sealed in the concrete; preferably removal of one or more protective elements, such as plug and / or foam, from said at least one opening face (which allows to connect a fitting or pipe to each outlet in the case of waiting hydraulic connections or to introduce a mechanism into the corresponding opening in the case of a recessed box or recessed tap body).

[0050] In one particular aspect, the formwork panels are vertical.

[0051] According to one embodiment, the process further includes, before positioning the second formwork, the step of connecting a hydraulic supply line to each inlet of the hydraulic connection device (and possibly connecting another line to the one or each outlet of the hydraulic connection device when the device is of the type recessed box or recessed valve body).

[0052] According to one embodiment, the depth dimension of the body is adjusted by adjusting the spacing between the body elements.

[0053] In particular, the cutting of the mesh, especially the mesh sheets, can be carried out opposite a face of the first metal formwork corresponding to the inner face, in an area and location corresponding to the desired positioning of the hydraulic connection device to allow the insertion of the system into the cut area and the application of the magnets to the first metal formwork.

[0054] According to one embodiment, the process further comprises the steps of: - connection of a hydraulic supply line to each inlet of the hydraulic connection device; - possibly connection of a hydraulic pipe to the outlet(s) of the hydraulic connection device when said outlet(s) are intended to be embedded (with said pipe) (i.e., intended to be embedded in the concrete to be poured between the formwork panels), particularly when the hydraulic connection device is: - a recessed housing (or enclosure) (for hydraulic use) intended to house a valve body, or - a built-in tap body; - positioning of a second metal formwork, and, when the hydraulic connection device is located on the opposite side of said at least one magnet, the inner face of the second formwork is applied against said at least one opening face of the hydraulic connection device; - pouring of concrete between the first formwork and the second formwork; - drying of concrete; - removal of the first formwork and the second formwork, the said hydraulic connection device being sealed in the concrete.

[0055] According to an embodiment in which the device includes hydraulic standby fittings, the process comprises the steps of: - connection of a hydraulic supply line to an inlet of each of the system's waiting hydraulic fittings (in particular after positioning the system on the first metal formwork by applying said at least one magnet to said formwork); when a pair of waiting hydraulic fittings is located on the side of said at least one magnet, the outlets of the waiting hydraulic fittings are preferably applied via protective element(s), such as plug and / or foam, against the first formwork, and before positioning the second formwork; (advantageously the outlet opening faces of the fittings are coplanar with the application face of said at least one magnet); - positioning of a second metal formwork, and, when hydraulic standby fittings are located on the side of the body opposite said at least one magnet, the inner face of the second formwork is applied against the outlet opening face of each hydraulic standby fitting of said pair of hydraulic standby fittings; - pouring of concrete between the first formwork and the second formwork; - drying of concrete; - removal of the first formwork and the second formwork, the said hydraulic fittings being sealed in the concrete.

[0056] Advantageously, after removal of any protective elements, such as plugs and / or foam, said at least one opening face of the hydraulic connection device, such as one opening face of each provisional hydraulic fitting, preferably with a normal horizontal axis, opens onto a facing the wall, the wall having an opening, i.e. an area devoid of concrete, opposite said opening of the hydraulic connection device.

[0057] According to an embodiment in which the device includes hydraulic standby fittings, the process comprises the steps of: - removal of said at least one magnet; - preferably, for each of the said hydraulic waiting fittings, removal of a foam located opposite an outlet of said hydraulic waiting fitting; - for each of the said hydraulic waiting fittings, removal of a plug which blocks an outlet of said hydraulic waiting fitting.

[0058] The removal of said at least one magnet can be done by unscrewing a retaining screw, for example using a hex key and then using a removal tool for said at least one temporary fixing element.

[0059] A method for installing wall-mounted taps in a concrete wall, preferably reinforced concrete, is also proposed. The method comprises the following steps: - positioning hydraulic standby fittings according to the method in any of the preceding embodiments in which the device includes hydraulic standby fittings, - after pouring and drying of the concrete, and removal of the formwork, connect a hydraulic pipe or a connecting fitting, for example straight or eccentric, to an outlet of each of the said waiting hydraulic fittings, for the connection of a valve device to the hydraulic pipes or connecting fittings.

[0060] Each connecting fitting can be straight or eccentric.

[0061] The first and second formwork panels extend at a distance from each other, preferably parallel, so that the hydraulic connection device's positioning system extends within the space defined between the two panels. It is understood that the system body is embedded after the concrete is poured between the panels. In one embodiment, the system body, each housing, the hydraulic connection device, and, where present, the additional hydraulic connection device, are embedded in the concrete. The protective element(s) of each opening face of the hydraulic connection device are removable after the concrete has dried and the formwork panels have been removed to access the face(s). an opening that leads to one side of the wall. Advantageously, at least one magnet is also removed.

[0062] The body of the system may include a frame, preferably rectangular, or a bar, for example made of metal. Brief description of the figures

Description of method(s) of implementation

[0081] Embodiments are described below with reference to the accompanying drawings. Similar numbers refer to similar features in all drawings. For the sake of brevity, some features may not be described opposite each figure, with the differences between the embodiments being described. The invention can be implemented in many different forms and should not be construed as being limited to the embodiments shown herein. The scope of the invention is defined by the accompanying claims.

[0082] A reference throughout the description to "an embodiment" means that a particular feature, structure, or characteristic described in relation to an embodiment is included in at least one embodiment of the present invention. Thus, the appearance of the phrase "in an embodiment" in various places throughout the description does not necessarily refer to the same embodiment. Furthermore, the features, structures, or particular characteristics may be combined in any suitable manner in one or more embodiments.

[0083] Figures illustrate several embodiments of system 1 for positioning a hydraulic connection device 1000.

[0084] Depending on the embodiment and as detailed below, the hydraulic connection device 1000 may include provisional hydraulic connections, a concealed valve body, or a concealed hydraulic housing for a wall-mounted valve body. The system may also include an additional hydraulic connection device 1001.

[0085] System 1 comprises a support body 10. The support body 10 can be formed by a substantially rectangular metal frame, for example illustrated in Figures 1 to 9. It can also be provided as explained later in the link with Figures 10 to 14 that the support body comprises several distinct elements 10A, 10B, preferably adjustable in spacing relative to each other (in the direction of depth) in order to be able to adapt to the distance between the two formworks and therefore to the thickness of the wall to be made.

[0086] It can be foreseen that the support body 10 has through holes for fixing, for example by rivets 15, the hydraulic connection device 1000, and possibly an additional hydraulic connection device 1001.

[0087] The system 1 also includes at least one magnet 2, preferably two magnets 2. The two magnets 2 are advantageously spaced longitudinally apart and preferably arranged, one at one longitudinal end of the body 10 and the other at the opposite longitudinal end of the body 10. The magnets 2 allow for secure temporary attachment of the system to a metal formwork panel before the system is embedded in the concrete intended to form the wall between the panels, as will be described later. Advantageously, the two magnets 2 are removable and reusable, as explained below.

[0088] Each magnet 2 comprises an application face 26 (magnetized) on a metal plate. The application faces 26 of the two magnets 2 are preferably coplanar.

[0089] Magnets

[0090] As mentioned above, the two magnets are advantageously spaced apart along a longitudinal direction of the system. The longitudinal direction corresponds to the direction along which the system is elongated, i.e., the longest dimension of the system. The longitudinal direction is orthogonal to the depth, or width, direction of the system. The depth, or width, direction of the system is parallel to the normal to the magnetized application surface of each magnet. In the illustrated embodiments, the magnets are located at the longitudinal ends of the system, in particular at the longitudinal ends of the support body 10.

[0091] In projection along the longitudinal direction of the system, the hydraulic connection device 1000 and, when present, the additional hydraulic connection device 1001, is or are located between the magnets 2.

[0092] Such an arrangement makes it possible to ensure the reliable positioning in space of the hydraulic connection device(s) when applying the system to the metal formwork.

[0093] According to one embodiment, as illustrated for example in Figures 1 to 3, each magnet 2 can be removably fixed on the body 10 for example by means of a screw 23 through a through passage 21, provided in a body of the magnet 2, and a thread 12 in the body 10.

[0094] In this embodiment, the through passage 21 includes a tapped hole cooperating with a guide piece 22 of the screw 23. The guide piece 22 can extend over a part, for example over about 50% (half), of the length of the through passage 21.

[0095] The guide piece 22 also includes a through passage 24 allowing the passage of the screw 23.

[0096] The diameter of the through passage 24 is greater than the diameter of the threaded shank of the screw 23, but less than the diameter of the head of the screw 23.

[0097] When the screw 23 is positioned, it does not protrude from the application surface 26.

[0098] According to the embodiment illustrated in Figures 1 to 3, the system 1 comprises, on one side of the body 10 opposite the magnets 2, a hydraulic connection device 1000. The hydraulic connection device 1000 comprises two hydraulic standby fittings 11 fixed to the body 10, for example, by means of bolts 101. Advantageously, the two fittings 11 have coplanar opening faces 110.

[0099] Preferably, each fitting 11 includes, before wall construction, a sealing plug 116 which seals the hydraulic outlet of the fitting 11 and, advantageously, a compressible foam 117 on the sealing plug 116. [000100] The compressible foam 117 allows the sealing plug 116 to be protected, preferably a hexagonal female recess of the sealing plug 116, at the time of pouring the concrete during the manufacture of the wall. [000101] Magnet housing [000102] According to other embodiments, illustrated for example in Figures 10 to 14, the system comprises, for each magnet 2, a housing 120 in which the magnet 2 is housed, preferably by press fitting. The housing 120 forms a housing with an opening that is closed by magnet 2. The application face 26 of the magnet can be flush with the opening of the housing 120 or extend slightly beyond it. Magnet 2 can be removed from the housing, for example using a tool 9 (Figure 15B), after the wall has been built and the formwork removed. [000103] Multi-part support body [000104] According to the embodiments, the support body 10 connects the magnets 2, or the magnet receiving housings 120 2, the hydraulic connection device 1000, and where applicable an additional hydraulic connection device 1001. [000105] As with the embodiments illustrated in Figures 10 to 14, it can be foreseen that the body 10 comprises a first element 10A, and a second element 10B. [000106] Preferably, the second element 10B of the body 10 has a U-shaped form and is preferably formed by a metal bar, for example a flat one, the end portions of which are bent at right angles. Each end portion bent at a right angle extends along said direction of separation of the elements 10A, 10B of the supporting body 10 relative to each other. [000107] According to an embodiment illustrated, for example, in Figure 11, the second element 10B carries the hydraulic connection device 1000, which includes, for example, two hydraulic connection fittings. In the example illustrated in Figure 11, the other element 10A does not have an additional hydraulic connection device 1001. According to an embodiment illustrated, for example, in Figure 12, said other element 10A is equipped with an additional hydraulic connection device 1001, for example, additional hydraulic fittings. [000108] The first element 10A has at least one portion parallel to, and separated from, at least one portion of the second element 10B, the separation being in a direction parallel to the normal of the application face 26 of said at least one magnet 2 (or parallel to the normal of the opening face of each of the two hydraulic waiting fittings which make up the hydraulic connection device). [000109] For fixing the element 10A to the housing 120, it can be provided that the end of the element 10A is insertable into a housing 14 integral with the separate housing from the housing which receives the end of element 10B, and that the end of element 10A is fixable inside housing 14 by an element such as a pin 140A, which facilitates the design of the system. [000110] According to an embodiment as illustrated in Figure 10, the support body 10 comprises the element 10A but is devoid of the element 10B. In this case the hydraulic connection device 1000 is fixed to the element 10A. [000111] Depending on the embodiment, it can thus be provided that element 10A carries the hydraulic connection device 1000 (which includes, for example, the two hydraulic standby fittings). Element 10B may be absent, as illustrated for example in Figure 10, or it may be present. [000112] According to another embodiment, as illustrated for example in Figure 11 or 12, it can be provided that the element 10B carries the hydraulic connection device 1000. The element 10A may be without a hydraulic connection device. [000113] According to another embodiment, as illustrated for example in Figure 13 or 14, it can be provided that the element 10A carries the hydraulic connection device 1000 and that the element 10B carries an additional hydraulic connection device 1001, for example additional waiting hydraulic fittings 11. [000114] Depth adjustment system [000115] The positioning system 1 includes a system for adjusting the position of the second element 10B relative to the first element 10A. The adjustment system is configured to adjust said spacing between the first element 10A and the second element 10B. [000116] The spacing direction is the depth direction in the system's operating situation, which corresponds to the spacing direction between the formwork panels between which the system is intended to be positioned by the magnets on one of said formwork panels. [000117] The adjustment system for the body elements 10 support may be a sliding adjustment system which includes, for example: - elements 103B, preferably positioning adjustment holes provided in, preferably through, opposite end portions of the second element 10B, such as right-angled folded ends of element 10B; - for each magnet receiving housing 120, an insertion housing 13, integral with said housing 120, into which one of said end parts of the second element 10B can be inserted to make a positioning adjustment element 103B of said end part of the second element 10B cooperate with a corresponding element 130B of the insertion housing 13. [000118] The corresponding element 130B is, for example, a pin 130B which can be inserted through an orifice 103B in an end portion of the element 10B of the support body. This orifice is positioned opposite another orifice 13B formed through a wall of the insertion housing 13, and the pin 130B passes through these orifices 13B, 103B to fix the insertion position of the second element 10B in the corresponding housing 13. [000119] According to a particular aspect, the end part of the element 10B can be inserted to an adjustable distance in the corresponding insertion housing 13 to define the spacing between the elements 10A, 10B. In particular, the spacing is a function of the orifice 103B which is chosen from the plurality of orifices to be brought opposite the orifice 13B of the insertion housing 13 and to be passed through (along with the orifice 13B) by the pin 130B. [000120] It can be foreseen that the magnet receiving housing 120 is formed in one piece, for example in plastic, with the insertion housing 13 of one end of the second element 10B of the support body 10, and, when present, the insertion housing 14 of one end of the first element 10A of the support body 10. [000121] Installation method [000122] The systems presented above allow for the implementation of a corresponding installation method. An embodiment of a method for installing wall-mounted taps in a reinforced concrete wall is described below. [000123] In a first step, a first metal formwork 6 is installed, as well as, preferably, two layers of metal mesh 8 opposite an inner face 62 of the first formwork 6, to form respectively part of the formwork and the metal skeleton of a reinforced concrete wall. [000124] To allow the insertion of system 1 at a location corresponding to the desired positioning of the hydraulic connection device, which This includes, for example, fittings 11; a cut is made in the metal mesh sheets 8 where present. The sheets are positioned opposite the first metal formwork 6. [000125] The system 1 is then positioned, advantageously through the cut part of the wire mesh 8, by applying the application faces 26 of the magnets 2 to the inner surface 62 of the first panel 6 at said location. [000126] Optionally, the body 10 can be tied to the wire mesh sheets 8 using iron wires 81. [000127] Each fitting 11 is then connected to a hydraulic supply line 118 at the inlet of the fitting 11. [000128] A second panel 7 is then positioned parallel to the first panel 6 so that an inner face 72 of the second panel 7 is applied against the foam 117 of the fittings 11. [000129] Concrete can then be poured between the first formwork 6 and the second formwork 7 to form the wall 67. [000130] Once the concrete has dried, the formwork panels 6 and 7 can be removed (formwork stripped), with system 1 sealed in wall 67. The opening face of the fittings 11 is flush with one face of wall 67, and wall 67 has a concrete-free area opposite the opening face of the hydraulic fittings. Wall 67 also has a concrete-free area opposite the application face of each magnet. [000131] In the embodiments shown in Figures 1 to 9, each screw 23 can be removed from the corresponding magnet 2 using, for example, a hex key. The magnets 2, which are no longer attached to the body 10, can be removed from the wall using a tool 9, as illustrated in Figure 4. The magnets 2 in the embodiments shown in Figures 10 to 15 can also be removed (from the corresponding housings 12) using tool 9. [000132] Once the magnets 2 are removed, the wall 67 includes two negative imprints 672 at the former positions of the magnets 2, as illustrated in Figure 5. The negative imprints can be formed from the inside of the housings 12 in the case of the embodiments of Figures 10 to 15. [000133] If the two negative impressions 672 are located on a wall face inside the building, they will preferably be filled in by the The mason will be applying the finishing plaster (particularly around the formwork joints and through holes left by the through-cylinders used for the large rods that assemble and secure the formwork panels). Therefore, no further intervention from the plumber is required. If the two negative impressions 672 are located on the building's facade, facade insulation will effectively cover them. Therefore, no further intervention from the plumber is required. [000134] At the hydraulic waiting connections 11, the protective element(s), such as foams 117 and plugs 116, can be removed to allow the installation of connecting connections, for example straight or eccentric, for connecting a valve device to the connecting connections. [000135] The invention is not limited to the embodiment just described. [000136] In the embodiment illustrated in Figure 6, and similarly for the embodiment of Figure 12, the system 1 includes two additional hydraulic standby fittings 11 positioned between the magnets 2. [000137] In these embodiments corresponding to Figures 6 and 12, during the manufacture of the wall 67, two fittings 11 will be located on the opposite side of the magnets 2 and in application of the formwork 7, the other two fittings 11 will be flush with the application faces 26 of the magnets 2 and in application of the metallic formwork 6. [000138] Figure 15 shows the magnetic attachment of the positioning system 1 of the embodiment of Figure 12 on one of the metal formwork panels, between the two metal formwork panels. [000139] Figure 15A shows the whole of Figure 15 in the poured state of the concrete between the formworks to form the wall 67 and in the removed state of the formworks, the body 10 of the system, the boxes 12, the hydraulic connection device 1000 (two waiting hydraulic connections in the example of Figure 15) and the additional hydraulic connection device 1001 (two additional waiting hydraulic connections in the example of Figure 15) being taken in the concrete. [000140] Figure 15B shows the whole of Figure 15A in the removed state of the magnets in relation to the corresponding housings and in the removed state of the foams 117 and plugs 116 of the waiting hydraulic fittings whose opening faces are flush with the corresponding faces of the wall. [000141] In the embodiment illustrated in Figure 7 or 10, the body 10 of the system 1 has a reduced depth and is formed by a metal bar which carries two fittings 11 positioned between the magnets 2. [000142] In these embodiments of Figures 7 and 10, during the manufacture of the wall 67, the two fittings 11 will be flush with the application faces 26 of the magnets 2. [000143] The system described above in the context of a hydraulic connection device 1000, and possibly an additional hydraulic connection device 1001, including hydraulic fittings for wall taps, also applies to other types of hydraulic connection devices for example illustrated in Figures 8, 9, 13 and 14. [000144] According to an embodiment illustrated, for example, in Figure 8 or 13, the hydraulic connection device 1000 comprises a wall-mounted, concealed valve body 11' having two inlets 112' (for example, for cold water and hot water inlets), each inlet being intended to be connected to a hydraulic supply line located between the two walls, and at least one outlet 113' (for example, a mixed water outlet) intended to be connected to another hydraulic supply line located between the two walls. Examples are illustrated in Figures 8 and 13, with the concealed body being the "Trio" concealed body for stop and diverter valves from the brand "HANSGROHE" (registered trademark), bearing the reference number 15981180. [000145] The embedded formwork body 1 T comprises a chamber having an opening closed by a sealing (or protection) system 119' against which the inner face of a formwork panel is applied. The sealing system 119' is thus removable after pouring and removal of the formwork panels. The sealing system 119' includes a plug (or cap) for protecting the inside of the body and preferably a foam for sealing the plug and for allowing the embedded formwork body to be compressed between the formwork panels. [000146] The embedded body has a control element, also called a cartridge, which controls the flow of fluid between each inlet and one or more outlets of the embedded body. The control element is designed to cooperate with a control system to be inserted into the hollow body through said opening. Thus, after removal of the formwork panels and the sealing system 119', Part of the valve control system, such as an on / off type valve handle, is inserted into the hollow body. The control system extends partially beyond the opening of the housing to be accessible to a user. [000147] According to another embodiment, the hydraulic connection device 1000 comprises a wall-mounted valve box or housing 11” with two inlets 112” (for example, hot water inlet and cold water inlet), each inlet being intended to be connected to a hydraulic supply line located between the two formwork panels, and at least one outlet 113” intended to be connected to another hydraulic supply line located between the two formwork panels. An example is shown in Figure 9 or 14, with the wall-mounted housing being the "iBox universal" housing from the brand "HANSGROHE" (registered trademark) bearing the reference 01800180. [000148] The 11” recessed housing may also include other outlets to supply a hand shower, an overhead shower, and / or a massage jet. [000149] The 11” recessed box defines a chamber having an opening closed by a sealing (or protection) system 119” against which the inner face of a formwork panel is applied. The sealing system 119” is thus removable after pouring and removal of the formwork panels. The sealing system 119” includes a plug (or cap) for protecting the inside of the 11” box and advantageously a foam for sealing the plug and for allowing the 11” recessed box to be compressed between the formwork panels. [000150] After removing the formwork and the 119" sealing system, a control device, also called a cartridge, is inserted into the chamber defined by the recessed housing and through said opening. This device controls the flow of fluid between each inlet and outlet of the recessed housing. A valve control system, such as a tap handle, cooperates with the control device and extends at least partially beyond the opening of the housing to be accessible to a user. [000151] The hydraulic connection device 1000, and / or the additional hydraulic connection device 1001, can be used in the fields of plumbing, heating and air conditioning. [000152] According to one embodiment, it can be provided that for a system equipped with a hydraulic connection device of the type of recessed body or recessed housing (or enclosure) for valve body, the outlet or each outlet of the body or housing is connected by a supply line forming a connecting line to an inlet of a hydraulic connection waiting for another positioning system which can be as described above, in particular equipped with several hydraulic connections waiting for. [000153] The method described above for embodiments in which the hydraulic connection device, and, optionally, the additional hydraulic connection device, including waiting hydraulic connections, also applies to embodiments in which the hydraulic connection device, and, optionally, the additional hydraulic connection device, includes (or include both) a concealed valve body or a concealed hydraulic housing. [000154] It is understood that in the case of a hydraulic connection device, such as a recessed valve body or a hydraulic recessed box, which includes inlets and one or more outlets which open into the space delimited between the two formwork panels, hydraulic pipes, intended to be embedded in the concrete, are connected to said inlets and outlet(s) before pouring and removal of the formwork panels, whereas in the case of a hydraulic connection device, such as a set of waiting fittings, whose outlets open onto a formwork panel, via the possible protective element(s), said outlets are connected to hydraulic pipes or fittings (which extend outward from the wall) only after pouring and removal of the formwork panels. [000155] When the depth dimension of the system body is adjustable, preferably by sliding, said dimension can be adjusted before the second formwork is put in place to adjust the depth of the body to the desired gap between the formworks.
