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 relates specifically to a hydraulic connection device positioning system, also called a sealing kit, and a method for positioning a connection device, such as a set of pre-installed hydraulic fittings, using such a system. Technological background

[0002] The construction of walls between two formwork panels or hips is a well-known practice in the building industry. This method consists of pouring concrete between two formwork panels or hips to form, or create 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 construct the wall between two haunches, then to excavate a vertical trench in this wall to create the necessary space for the supply piping and the 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, although common, is not entirely satisfactory due to the chipping required on the newly constructed wall and the necessary sealing operations to fix the supply pipes and the pre-installed hydraulic fittings before the taps can be fitted. Indeed, this requires several complex and time-consuming interventions that demand expertise in techniques from various trades.

[0005] The number of interventions, the waste of manpower, 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 a hydraulic connection device, such as hydraulic fittings for wall-mounted taps, in a reinforced concrete wall. This need exists in various hydraulic fields, including plumbing, heating, and air conditioning.

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

[0008] A positioning system for a hydraulic connection device is proposed, characterized in that said system comprises: - a body; - at least one temporary fixing element on a formwork, said at least one temporary fixing element being fixed to the body of the system; - a hydraulic connection device fixed to the body of the system, the hydraulic connection device comprising at least one inlet intended to be connected to a hydraulic supply line and at least one hydraulic outlet intended to be connected to a hydraulic line or to a hydraulic fitting.

[0009] Thanks to the presence of at least one temporary fixing element on a formwork panel, the present system can be positioned on a formwork panel before the installation of another closing formwork panel and before the concrete is poured between the two panels. The invention thus makes it possible to pre-position the hydraulic connection device of the system, for example hydraulic fittings, before the wall is constructed.

[0010] Advantageously, said at least one temporary fastening element has a configuration adapted to prevent rotation of the system when fixed to the formwork. In particular, when said at least one temporary fastening element includes a magnet, the magnet may be provided to be elongated, preferably rectangular, and of a size adapted to prevent rotation of the system.

[0011] The system allows for easy positioning of the hydraulic connection device in space. This is particularly the case when said device includes pre-installed hydraulic connections. In particular, the space between the hydraulic connections is predefined and maintained by the body of the system, which, in combination with said at least one temporary fixing element, allows for good alignment of the hydraulic connections on several planes and axes, particularly in depth, and also with respect to the horizontal and vertical planes.

[0012] Once the concrete has been poured, the hydraulic connection device is fixed to the wall by being embedded in the concrete. These hydraulic fittings are fixed to the wall, and the plumber then only needs to connect a tap, without having to drill into the wall. The tap could be, for example, a radiator, shower, bathtub, sink, or washing machine tap.

[0013] Said at least one temporary fastening element is configured, when temporarily fixed to a formwork, to generate a holding force enabling to compensate at least for the weight of the system and the pressure of the concrete when poured from the top of the two formwork panels. In other words, said at least one temporary fixing element is configured, when temporarily fixed to a formwork panel, to generate a holding force preventing movement of the system relative to the formwork panel, without external intervention.

[0014] 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).

[0015] According to one embodiment, said at least one temporary fastening element is removably fixed to the body of the system.

[0016] According to one embodiment, said at least one temporary fastening element comprises a magnet.

[0017] The use of a magnet has the advantage of allowing the magnet to be reused when it is removable from the body of the system. Preferably, the magnet or magnets are configured to exert a force of at least 800 Newtons.

[0018] The use of a magnet allows, through the very strong attraction produced by the magnet on the metal of a formwork panel, for a firm and rapid attachment to the metal panel, without significantly increasing the difficulty of removing the panel after a wall has been built. Formwork panels are generally made of metal, but the invention can be applied to non-metallic formwork, for example, wood. In particular, the magnet(s) can be replaced by one or more metal or plastic parts of the same configuration (advantageously having a hole for attachment to the body of the system and for removal) and of the same thickness as the magnet(s), which can be fixed using nails whose length is calculated to penetrate only 1.5 centimeters into the wooden formwork. Alternatively, each magnet can be pre-drilled to allow for nailing when using wooden formwork.

[0019] Alternatively, said at least one temporary fastening element is temporarily fixed to a non-metallic formwork, for example, by bonding, for example using an adhesive such as double-sided tape. The system is advantageously reinforced by wire ties allowing the body of the system to be connected to welded wire mesh sheets.

[0020] Alternatively, said at least one temporary fixing element is fixed using a suction cup.

[0021] According to one embodiment, said at least one temporary fastening element is removably fixed to the body of the system.

[0022] This removable attachment of said at least one temporary fixing element to the body allows, after the wall has been built and the formwork removed, said at least one temporary fixing element to be recovered from the wall, so that it or they can be retrieved for reuse. Said at least one temporary fixing element thus removed can also be reused to assemble a new system.

[0023] Alternatively, said at least one temporary fastening element is not removable from the body. This can, for example, limit the manufacturing cost of the system when the flush part of said at least one fastening element does not cause an aesthetic problem and does not weaken the finishing coating.

[0024] According to one embodiment, to ensure the removable connection between said at least one temporary fastening element and the body of the system, said at least one temporary fastening element comprises a guide piece for a screw, said piece being fixed inside a through passage provided in a body of said at least one temporary fastening element, and the body of said at least one temporary fastening element having a thread adapted to cooperate with an external thread of the guide piece.

[0025] According to one embodiment, the through passage provided in the body of said at least one temporary fastening element is configured to have a thread adapted to cooperate with a thread of a part of a removal tool of said at least one temporary fastening element.

[0026] According to one embodiment, said at least one temporary fastening element comprises two temporary fastening elements, preferably two removable magnets, having coplanar application faces.

[0027] Having two temporary fixing elements allows for better support of the system on the formwork, in particular limiting the risks of rotation.

[0028] According to one embodiment, the hydraulic connection device comprises two hydraulic waiting fittings fixed on the body of the system and having coplanar opening faces.

[0029] According to one embodiment, the hydraulic connection device comprises four hydraulic standby fittings fixed on the body of the system in pairs.

[0030] According to one embodiment, the hydraulic connection device includes a recessed valve body.

[0031] According to one embodiment, the hydraulic connection device includes a hydraulic recessed box.

[0032] A method for positioning a hydraulic connection device, such as hydraulic standby fittings, is also proposed using a system according to any one of the preceding embodiments, the method comprising the following steps: - possibly, cutting two sheets of wire mesh; - positioning of the system by applying one application face of said at least one temporary fixing element of the system against one face of a first formwork panel, preferably metallic, and at a location corresponding to a desired position of the hydraulic connection device, said at least one temporary fixing element being applied against the inner face of the first formwork panel and the hydraulic connection device being located: - either on the opposite side of the said area at least one temporary fixing element, - either flush with the application face of said at least one temporary fixing element.

[0033] A method for positioning hydraulic standby fittings using a system according to any one of the preceding embodiments is also proposed, the method comprising the following steps: - possibly, cutting two layers of a metal mesh; - positioning of the system by applying one application face of said at least one temporary fixing element of the system against one face of a first formwork panel, in particular metallic, and at a location corresponding to the desired positioning of said hydraulic waiting fittings, said at least one temporary fixing element being applied against the inner face of the first formwork panel and said hydraulic waiting fittings being located: - either on the opposite side of the said area at least one temporary fixing element, - either flush with the application face of said at least one temporary fixing element.

[0034] In particular, the cut of the mesh sheets can be located opposite a face of the first formwork corresponding to the inner face, in an area and at a location corresponding to the desired positioning of the hydraulic connection device, for example each hydraulic connection, to allow the insertion of the system into the cut area.

[0035] According to one embodiment, the hydraulic connection device is located on the opposite side of at least one temporary fixing element.

[0036] According to one embodiment, said hydraulic waiting connections are located on the opposite side of said at least one temporary fixing element.

[0037] According to one embodiment, the hydraulic connection device has a part located flush with the application face of said at least one temporary fixing element.

[0038] According to one embodiment, said hydraulic waiting connections are located flush with the application face of said at least one temporary fixing element.

[0039] Each waiting hydraulic fitting has an opening face (outlet face), preferably with a horizontal axis, flush with a face of the wall, the wall having an opening, i.e. an area without concrete, opposite said opening of the hydraulic fitting.

[0040] According to one embodiment, said hydraulic waiting connections comprise two hydraulic waiting connections, one of the two hydraulic waiting connections is located on the opposite side of said at least one temporary fastening element, the other of the two hydraulic waiting connections is flush with the application face of said at least one temporary fastening element.

[0041] According to one embodiment, the process further comprises the steps of: - connection of a hydraulic supply line to the inlet(s) of the hydraulic connection device; - possibly connection of a hydraulic pipe to the outlet or each outlet of the hydraulic connection device when said outlet is intended to be embedded (with said pipe), in particular when the hydraulic connection device is a hydraulic recessed box or a recessed valve body; - positioning of a second formwork, preferably metallic, and, when at least part of the hydraulic connection device is located on the opposite side of said at least one temporary fixing element, the inner face of the second formwork is applied against said at least part 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.

[0042] According to an embodiment in which the device includes hydraulic standby fittings, the method comprises the steps of: - connection of a hydraulic supply line to an inlet of each of the system's standby hydraulic fittings; - positioning of a second formwork, preferably metallic, and, when at least part of the hydraulic fittings (said at least part preferably including a pair of waiting hydraulic fittings) is located on the opposite side of said at least one temporary fixing element, the inner face of the second formwork is applied against said at least part of the hydraulic fittings (preferably against an outlet face of each waiting hydraulic fitting of said pair of waiting hydraulic 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.

[0043] Advantageously, one face of the hydraulic connection device, such as an opening face of each waiting hydraulic connection, preferably with a horizontal axis, is flush with one face of the wall, the wall having an opening, i.e. an area devoid of concrete, opposite said opening of the hydraulic connection.

[0044] According to an embodiment in which the device includes waiting hydraulic fittings, the method further includes the steps of: - removing said at least one temporary fastening element; - preferably, for each of the said hydraulic waiting fittings, removal of a foam located opposite an outlet of said hydraulic fitting; - for each of the said hydraulic waiting fittings, removal of a plug which blocks an outlet of said hydraulic fitting.

[0045] The removal of said at least one temporary fastening element 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 fastening element.

[0046] 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 connection points according to the method according to any of the preceding embodiments for which the device includes hydraulic connection points, - connecting a hydraulic line or a connecting fitting, for example straight or eccentric, to an outlet of each of said hydraulic connection points, for the connection of a tap device to the hydraulic lines or connecting fittings.

[0047] Each connecting fitting can be straight or eccentric.

[0048] The first and second hips extend apart from each other, preferably parallel to each other, so that the hydraulic connection device positioning system extends into the space defined between the two hips. It is understood that the body of the system is embedded following the pouring of concrete between the hips.

[0049] The body of the system may include a frame, preferably rectangular, or a bar, for example made of metal. Brief description of the figures

[0060] 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.

[0061] A reference throughout the description to "an embodiment" means that a particular functionality, structure, or feature described in relation to an embodiment is included in at least one embodiment of the present invention. Thus, the appearance of the expression "in an embodiment" in various Locations throughout the description do not necessarily refer to the same embodiment. Furthermore, features, structures, or special characteristics can be combined in any suitable way in one or more embodiments.

[0062] Figures 1 to 3 illustrate a first embodiment of system 1 for positioning hydraulic waiting fittings according to the invention.

[0063] The system 1 comprises a body 10, for example formed by a substantially rectangular metal frame.

[0064] The system 1 also includes two magnets 2. The two magnets can be separated from each other and positioned, one on one lateral side of the body and the other on the opposite lateral side of the body 10. The magnets allow for secure temporary attachment to a formwork, as will be described later. Advantageously, the two magnets 2 are removable and reusable, as explained below.

[0065] The magnets 2 each comprise an application face 26 on a base. The application faces 26 of the two magnets 2 are, in this example, coplanar.

[0066] Each magnet 2 is removably fixed to the body 10 preferably 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.

[0067] In this embodiment, the through passage 21 includes a thread 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.

[0068] The guide piece 22 also includes a through passage 24 allowing the passage of the screw 23.

[0069] 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.

[0070] When the screw 23 is positioned, it does not protrude from the application surface 26.

[0071] The system 1 also includes, on one side of the body 10 opposite the magnets 2, at least two hydraulic standby fittings 11 fixed to the body 10 using bolts 101.

[0072] In this embodiment, the two fittings 11 have coplanar opening faces 110.

[0073] Each fitting 11 includes, before wall fabrication, a compressible foam 117 above a sealing plug 116 which seals the hydraulic outlet of the fitting 11 and the sealing plug 116.

[0074] 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.

[0075] A method for installing wall-mounted taps in a reinforced concrete wall is described below.

[0076] In a first step, a first formwork 6 is installed, as well as, preferably, two layers of wire 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.

[0077] To allow the insertion of the system 1 at a location corresponding to the desired positioning of the fittings 11, a cut is made in the metal mesh sheets 8 when they are present.

[0078] The system 1 is then positioned by applying the application faces 26 of the magnets 2 to the inner surface 62 of the first panel 6 at said location.

[0079] Optionally, the body 10 can be tied to the wire mesh sheets 8 using iron wires 81.

[0080] Each fitting 11 is then connected to a hydraulic supply line 118 at the inlet of the fitting 11.

[0081] 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.

[0082] Concrete can then be poured between the first formwork 6 and the second formwork 7 to form the wall 67.

[0083] Once the concrete has dried, the hips 6 and 7 can be removed (formwork removal), the system 1 being sealed in the wall 67 with an opening face of the fitting 11 flush with a face of the wall 67, the wall 67 having an area devoid of concrete, opposite said opening face of the hydraulic fitting.

[0084] Using a hex key, for example, each screw 23 can be removed from the corresponding magnet 2. The magnets 2, which are no longer fixed to the body 10, can be removed from the wall using a tool 9, as illustrated in [Fig. 4].

[0085] Once the magnets 2 have been removed, the wall 67 includes two negative imprints 672 at the former positions of the magnets 2, as illustrated in [Fig.5].

[0086] If the two negative impressions 672 are located on a wall face inside the building, they should preferably be filled by the mason when applying the finishing plaster (particularly at the formwork joints and through holes left by through-cylinders for the large rods used to assemble and secure the hips). Therefore, no further intervention by the plumber is required. If the two negative impressions 672 are on the building's facade, facade insulation will advantageously cover them. Therefore, no further intervention by the plumber is required.

[0087] At the fittings 11, the foams 117 and the plugs 116 can be removed to allow the installation of connecting fittings, for example straight or eccentric, for connecting a valve device to the connecting fittings.

[0088] The invention is not limited to the embodiment just described.

[0089] In one variant, illustrated in [Fig.6], the system 1 includes two additional fittings 11 positioned between the magnets 2.

[0090] In this variant, during the manufacture of the wall 67, two fittings 11 will be located on the opposite side of the magnets 2, the other two fittings 11 will be flush with the application faces 26 of the magnets 2.

[0091] In the variant of [Fig. 7], the body 10 of the system 1 has a reduced width and is formed by a metal bar. In addition, the system 1 comprises at least one, preferably two, fittings 11 positioned between the magnets 2. In this variant, during the fabrication of the wall 67, the two fittings 11 will be flush with the application faces 26 of the magnets 2.

[0092] In an unillustrated embodiment, the application faces 26 of the two magnets 2 could extend in planes forming a non-zero angle between them, for example at 45°. Such a configuration can allow the installation of a tap at the junction between two walls of a building.

[0093] The system described above in the context of a hydraulic connection device which includes hydraulic fittings for wall taps, also applies to other types of hydraulic connection devices.

[0094] According to another embodiment, the hydraulic connection device comprises a wall-mounted valve body 11' having at least one inlet 112' for connection to a hydraulic supply line located between the two halves and at least one outlet 113' for connection to another hydraulic supply line located between the two halves. An example is shown in [Fig. 8], with the wall-mounted body being the "Trio" wall-mounted valve body for a stop valve and diverter from the brand "HANSGROHE" (registered trademark) bearing the reference number 15981180.

[0095] The embedded body 11' comprises a chamber having an opening sealed by a sealing 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 a foam for sealing the plug and for allowing the embedded body to be compressed between the formwork panels.

[0096] The mounting body has a control element, also called a cartridge, which controls the flow of fluid between the inlet and outlet of the mounting body. The control element is designed to cooperate with a system of control to be inserted into the hollow body. Thus, after removal of the formwork and the sealing system 119', a part of the valve control system, such as an on / off type valve handle, is inserted into the hollow body.

[0097] According to another embodiment, the hydraulic connection device comprises a recessed 11” box or housing for wall-mounted valves having at least one 112” inlet for connection to a hydraulic supply line located between the two formwork panels and at least one 113” outlet for connection to another hydraulic supply line located between the two formwork panels. An example is shown in [Fig. 9], with the recessed housing being the "iBox universal" housing from the "HANSGROHE" brand (registered trademark) bearing the reference 01800180.

[0098] The 11” recessed box defines a chamber that has an opening closed by a closure system 119” against which the inner face of a formwork panel is applied. The closure system 119” is thus removable after pouring and removal of the formwork panels. The closure system 119” includes a plug (or cap) for protecting the inside of the 11” box and foam for sealing the plug and allowing the 11” recessed box to be compressed between the formwork panels.

[0099] After removing the formwork and the sealing system 119”, a control unit, also called a cartridge, is introduced into the chamber defined by the recessed box, allowing the passage of fluid between the inlet and outlet of the recessed box to be controlled, a valve control system, such as a tap handle, which cooperates with the control unit.

[0100] The hydraulic connection device may also be a device other than those shown in the examples or embodiments above, in the fields of plumbing, heating and air conditioning.

[0101] 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 box, the outlet or each outlet of the body or box is connected by a supply line forming a connecting line to an inlet of a hydraulic connection of a system as described above equipped with several hydraulic connections.

[0102] It is understood that in the case of a hydraulic connection device, such as a recessed body or recessed box, which includes an outlet opening into the space delimited between the two formwork panels, a hydraulic pipe, intended to be embedded in the concrete, is connected to said outlet before pouring and removal of the formwork panels, whereas in the case of a hydraulic connection device, such as a set of connecting fittings, whose outlet(s) open onto a formwork panel, said The outlet is only connected to a hydraulic pipe or fitting after the hips have been poured and removed.

[0103] The invention is not limited to the embodiments illustrated in the drawings. Consequently, it must be understood that, where the features mentioned in the appended claims are followed by reference numerals, these numerals are included solely for the purpose of improving the intelligibility of the claims and are in no way limiting the scope of the claims.

[0104] Furthermore, the term "including" does not exclude other elements or steps. In addition, features or steps that have been described with reference to one of the embodiments set out above may also be used in combination with other features or steps from other embodiments set out above.
