Description

Method for mounting a kit for fixing a tap to a partition, in particular to a plasterboard partition

The present invention relates to a method for mounting a kit for fixing a tap to a partition, in particular to a plasterboard partition.

In the building sector, there are kits for fixing taps to plasterboard partitions. These kits allow for example to fix a bathtub faucet (or mixer) on a bathroom partition.

FR 3,038,629 B1 discloses an example of a fixing kit. The kit includes two fittings, in particular elbow fittings, each comprising a first connection piece for a pipe and a second connection piece for the tap. The assembly of this kit is carried out as follows. First, the two fittings are connected to the end of the water supply tubes, which are on standby in a configuration where they protrude through the partition. Then fix a plate on the interior face of the partition, that is to say the face turned towards the bathroom, taking care to engage the second connection end piece of each connection through an opening of the plate. A nut is then screwed around the second end piece of each fitting and this nut is fixed to the plate by screwing. This immobilizes each fitting relative to the plate, and therefore relative to the partition. A tap is subsequently fitted on the two connecting ends projecting from the plate.

There are other examples of kit, such as for example that described in FR 3 023 309 A1, the fixing of which is effected by adhesion.

In these two kits, and more generally in all existing fixing kits, there is the presence of a plate to secure the fittings. Conventionally, this plate is fixed on the interior face of the partition, that is to say on the side of the location provided for the tap.

Basically, the method is more or less always the same. The installer drills two holes in the plasterboard to recover the pipes, then waiting behind the partition, makes the connection with the fittings and fixes the plate assembly plus fittings on the internal face of the partition. This method poses a number of difficulties. Firstly, the operation of recovering the pipes behind the pipeline and pulling these pipes through the holes drilled in the partition is relatively painful, especially when the pipes are rigid. Second, it is often necessary to push the pipes inside the holes in the partition to fix the fittings to the plate, which is also painful when the pipes are rigid pipes for example. Third, the presence of the partition can hinder the installer when connecting the pipes to the corresponding fittings. Typically, the installer may run out of space.

All these constraints make the kits of the prior art relatively difficult to install, with an often long assembly time.

It is to these drawbacks that the invention more particularly intends to remedy, by proposing a new method making it possible to mount the kit more quickly and more easily on the partition.

To this end, the invention relates to a method of mounting a kit for fixing a tap to a partition, in particular to a plasterboard partition, this method comprising steps consisting in:

a) attach at least one connector to a plate, each connector comprising a first connector for connection to a water supply pipe and a second connector for connecting the tap,

b) connect each fitting to a corresponding water supply pipe,

c) make at least one hole in the partition for the passage of the second end piece of each fitting through the partition,

d) place the partition in front of the plate,

e) pull the second connection end piece of each connection through a hole in the partition, and

f) fix the plate on a rear face of the partition, on the side opposite to the location provided for the tap.

Thanks to the invention, the installer is not hampered by the partition when connecting with the pipes because the fittings are connected to the ends of the pipes before the installation of the partition. In addition, the installer no longer needs to pull the pipes through the holes in the partition to be able to connect the elbow fittings, nor push the pipes back into the holes to fix the fittings to the plate. This greatly facilitates the task. Also, since the plate is fixed on the hidden face of the partition, it poses no difficulty when laying the tiling or other wall covering.

According to advantageous, but not mandatory, aspects of the invention, such a process can include one or more of the following characteristics, taken in any technically admissible combination:

- the tap is a bath mixer,

- step b) consists of connecting two pipes, respectively of hot and cold water, to corresponding fittings fixed to the plate, and step c) consists of making two holes in the partition, respectively for the passage of the second connection end piece of the two fittings;

- a step subsequent to step e) and prior to step f), consists in using a level, such as a spirit level, to bring the two fittings up to one another;

a step subsequent to step e) and prior to step f), consists in screwing a nut around the second end piece of each fitting, preferably after the two fittings have been leveled with respect to one the other ;

- each nut has an outside diameter greater than the diameter of the hole or holes made in the partition in step c);

- in step f), the plate is fixed to the partition by self-tapping screws screwed from the side of the partition opposite the plate and, in step f), a screwing template is preferably used;

- at least one gripping member is fixed to the second connection end piece of each connection to facilitate the implementation of step e);

- a step subsequent to step b) and prior to step c), consists in temporarily fixing the plate at a certain height above the ground.

The invention also relates to a method of fixing a tap to a partition, in particular to a plasterboard partition, this method consisting in mounting a kit according to the mounting method defined above, then in connecting the tap with the second end piece. of each connection.

The invention also relates to a fixing kit, for implementing the fixing method defined above, this kit comprising at least one connector, comprising a first connector for connecting to a pipe and a second connector for connecting the tap, a plate intended to be fixed to the partition and fixing means, to fix each fitting on the plate. According to the invention, the kit comprises, for each connector, a gripping member capable of being removably attached to the second end of the connector.

According to advantageous, but not mandatory, aspects of the invention, such a kit may include one or more of the following characteristics, taken in any technically admissible combination:

- Each gripping member is configured to help an installer pull the second connection end piece of the fitting through a hole in the wall when mounting the kit.

- Each gripping member is screwed to the second connection end of a connection, in particular inside a threaded hole of the second connection end.

- Each gripping member forms a tight plug.

The kit includes, for each fitting, a nut, intended to be screwed around the second end of the fitting.

- Each gripping member has a cylindrical part for positioning a level, such as a spirit level.

- Each gripping member is removed at the time of fitting the tap.

The plate comprises one or more stiffeners, preferably formed by bosses.

The plate includes in the center, a preferential break line, which allows the plate to be cut in half by folding.

- Each fitting is a bent fitting.

Figures 12 and 13 are views comparable to Figures 8 and 9, respectively, for a third embodiment of a mounting kit.

Figures 1 to 7 are representations of the different stages of the process which is the subject of the invention. The purpose of this process is to mount a kit 100 for fixing a tap (not shown) to a partition 2, in particular to a plasterboard partition, of the placo type (registered trademark). Typically, the partition 2 is a finishing partition, not to be confused with the masonry (wall) which generally has a mechanical bearing function and which is completely irremovable. In the example, the partition 2 advantageously has a thickness of 13 mm, but the kit 100 can be mounted on a partition of different thickness. To be complete, the partition 2 has no lift function, but only a finish function.

The kit 100 is better represented in FIGS. 8 and 9. Once mounted on the partition 2, the kit allows, on the one hand, to mechanically fix the tap to the partition 2 and, on the other hand, to interface for the connection between the tap (or mixing valve) and two pipes (or conduits) 4, for supplying hot and cold water respectively, extending behind the partition 2.

Typically, the pipes 4 may be of the flexible type, for example made of PER (crosslinked polyethylene), or rigid, for example of multilayer.

In what follows, the space at the front of the partition 2 designates the space provided for the location of the tap, that is to say typically the interior volume of the bathroom, while the space at the rear of the partition 2 designates the space where the pipes 4 pass. Generally, the space at the rear of the partition 2 is a space delimited between the partition 2 and the masonry (represented by bricks in FIGS. 1 to 4). This definition can be transposed for identifying the front and rear directions. Thus, the front face of the partition 2 is a face turned towards the side of the location provided for the tap, while the rear face is generally turned towards the masonry of the building, that is to say towards the wall.

In the first example, that is to say in the example of FIGS. 1 to 9, the kit 100 comprises a plate 102, preferably of rectangular shape, two connectors 110, two nuts 130 and two gripping members 122.

In the example, the plate 102 is a sheet metal plate, in particular 0.6 mm thick.

The plate 102 cleverly includes, in the center, a preferential break line 104, which makes it possible to cut the plate 102 in two by folding. This preferred break line 104, or break line, is in fact formed by at least one, preferably three oblong openings aligned with each other in the height direction of the plate 102. This allows the kit to be adapted. when mounting an insulated tap, like the tap on a household appliance or a single tap. This is called a "single-hole" kit.

Advantageously, each connector 110 is an elbow connector, for example made of brass.

Each connector 110 comprises a first connector 112 for connection to a pipe 4 and a second connector 114 for connection to the tap. In the example, the second end piece 114 is a end piece qualified as a female end piece / 2, making it possible to receive offset fittings (not shown) supplied with the fittings, that is to say with the tap. Each end piece 114 therefore comprises an internal thread. The end piece 112 comprises corrugated shapes forming baffles for connection with a pipe 4. Typically, the connection between the end piece 112 and the tube 4 is made by means of a slip fitting, a crimp fitting or still a compression fitting (not shown). The connection operation is generally carried out using pliers.

Advantageously, each end piece 114 also includes an external thread for positioning a nut 130. When they are screwed around the end pieces 114, the plate 102 is pressed against the rear surface of the partition 2, and the end pieces 114 are pulled out. through holes 3 made in the partition 2. Effectively, the nuts 130 are configured to bear against the front face of the partition 2. For this, the nuts 130 advantageously have an outside diameter greater than that of the holes 3 made in the partition 2.

Each connector 110 comprises a collar 116 for fixing to the plate 102. In particular, the collar 116 is screwed onto the plate 102. In the example, there are four screws 118. The screws 118 pass through holes in the plate 102 and engage in complementary threads of the flange 116.

The plate 102 comprises two passage openings for the connectors 110. Advantageously, the plate 102 comprises a recess 108 around the openings to receive the flange 116 of each connector 110. Each recess 108 extends towards the rear, that is that is to say defines a boss on the rear face of the plate 102 (or the face of the plate turned towards the masonry). The depth of each recess

108 is substantially identical to the thickness of the flange 116 of the two connections 110, so that the flange 116 of the two connections is flush with the front surface of the plate 102. This makes it possible, among other things, to have no space between the plate 102 and the partition 2 when the kit is mounted on the partition 2.

In practice, the fittings 110 are delivered in the kit in a configuration where they are already mounted, that is to say fixed, on the plate 102.

Preferably, a gripping member 122 is provided around the second connecting end piece 114 of each fitting 110 to help the installer pass the fittings 110 through the holes in the partition 2. Typically, these gripping members 122 are handles of maneuver (or installation accessories).

Also, the gripping members 122 are delivered pre-assembled, that is to say already assembled with the fittings 110. To do this, each gripping member 122 is screwed inside a corresponding end piece 114. Thus , each gripping member 122 comprises an external male thread 123 complementary to the internal (female) thread of the end pieces 114.

Advantageously, the gripping members 122 take the form of two plugs (or caps), of elongated shape. Thus, these two plugs make it possible to prevent foreign bodies (dust, plaster or other) from entering inside the fittings 110 and a fortiori inside the water distribution network during the period preceding the installation of the tap. The two plugs also allow leak tests to be carried out before commissioning.

Preferably, the members 122 are respectively red and blue in color. The red plug is located on the side of the hot water pipe, while the blue plug is located on the side of the cold water pipe. These two members 122 are removed at the time of fitting the tap.

The method of mounting the kit 100 on the partition 2 is described below.

First, the installer cuts the pipes 4 to obtain a certain length depending on the height desired for the installation of the tap. Before or afterwards, during a step a), it is necessary to fix each fitting 110 to the plate 102, by screwing the screws 118 in the holes of the plate 102 and in the threads of the flange 116. In practice, the fittings 110 are delivered pre-mounted on the plate 102, that is to say that step a) is not implemented by the installer, but by the manufacturer of the kit 100. Note that the fittings 110 are, in the first embodiment, fixed to the front of the plate 102.

Then, the installer connects, in a step b), each connection 110 to a corresponding water supply pipe 4. In particular, the two pipes 4 are connected with the corresponding end pieces 112 of the connections 110 fixed to the plate 102. For this, the installer uses, in a manner known per se, a slip, compression or crimp connection and a clamp (not shown) to tighten the connection.

Preferably, and in particular in the case where there are flexible pipes, for example in PER, the kit 100 is temporarily fixed on the masonry, for example using a pin, which is threaded into an oblong opening of the plate to temporarily support the plate 102 at a certain height. At this point, the kit 100 is at approximately the correct height from the height of the valve location. Temporary fixing is generally not necessary in the case of rigid pipes, for example in multilayers.

Subsequently, at least one hole is made during a step c), preferably two holes 3 in the partition 2, respectively for the passage of the second connection end piece 114 of the two connections 110. Typically, these two holes 3 can be made using a hole saw. It is therefore understood that the holes 3 are made before the installation of the partition 2.

In step d), the partition 2 is placed in front of the plate 102. To do this, as shown in FIG. 3, a structure 6 is installed in the form of a frame for supporting the partition 2. Advantageously, the uprights and crosspieces of the structure 6 are made in the same grade of steel as the plate 102, and have, in section, the same sheet thickness.

We then rock the partition 2 against the structure 6, taking care to align the holes 3 with the position of the gripping members 122. At this stage, the gripping members 122 are at least partially inserted in the holes 3 of the partition 2. The partition 2 is then fixed to the structure 6, in particular by screwing.

Then, in a subsequent step e), the second connection end piece 114 of each connection 110 is passed through the partition 2. For this, the installer pulls, with his fingers, on the gripping members 122 towards the 'before, so as to pull the end pieces 114 through the holes 3 of the partition 2 and to press the plate 102 against the rear face of the partition 2.

The installer then threads the nuts 130 around the plugs 122 and the end pieces 114, and can slightly screw the nuts 130 around the end pieces 114, for example until the nuts 130 abut against the front face of the partition 2 The nuts 130 actually have a diameter greater than that of the holes 3 in the partition 2.

Before tightening the nuts 130, the installer can advantageously take advantage of this to level the two end pieces 114. Indeed, the holes 3 are provided with a larger diameter to facilitate the passage of the fittings 110. In other words, there is a certain clearance, on each side, in all radial directions relative to a central axis of the holes 3. It is therefore possible that one of the end pieces 114 is slightly higher than the other. This can be checked using a level 8 which, in the example, is a spirit level. The gripping members 122 advantageously each have a perfectly cylindrical part 125 for positioning the spirit level.

The installer then adjusts the positioning of the end pieces 114 in order to obtain that the two end pieces 114 are at the same level, that is to say at the same height. Once the spirit level indicates perfect horizontality, the installer then tightens the nuts 130, which has the effect of moving the fittings 110 and the plate 102 forwards. The plate 102 is then pressed completely against the rear face of the partition 2 and the end pieces 114 pass through the partition 2 until reaching a configuration (FIG. 6), where they can be connected with complementary offset fittings (not shown) serving fixing the fittings. This type of fitting is known per se, which is why there is no further explanation on this subject.

Subsequently, in stage f), the plate 102 is fixed to the partition 2, on the side opposite to the location provided for fixing the valve, that is to say on the rear face of the partition 2 In particular, the plate 102 is fixed to the partition 2 by self-tapping screws (or self-drilling) 10, which are also supplied in the kit and which are screwed from the side of the partition 2 opposite the plate 102, c 'ie from the front side of partition 2. The installer can use a suitable screwdriver.

Advantageously, a screwing template 12 is used to screw the screws 10 into the plate 102. This template 12 has the shape of a rectangular plate provided with different holes indicating where the screws 10 must be positioned. This template 12 is provided in kits 100 and 200. It can be a rigid or flexible plate, for example made of plastic, a cardboard sheet, etc. The template 12 includes a marking "UP" to indicate to the installer how the template 12 should be oriented relative to the ground. The template 12 can also include self-adhesive means (adhesive tape or the like) to adhere alone to the partition 2.

The screws 10 pierce the partition 2, then the plate 102. By crossing the partition 2 and the plate 102, the screws 10 create tapped holes (principle of self-tapping screws), which makes it possible to secure the screws 10 to the partition 2 and to the plate 102. To avoid any deflection of the plate 102 during the tightening of the screws 10, the plate 102 comprises a plurality of stiffeners 106, which extend in the vertical direction, and which are in fact directed recesses, like recess 108, backwards. This means that the stiffeners form bosses at the rear of the plate 102.

At this stage, the fixing kit 100 is mounted. The partition 2 is then awaiting fixing of the valve. During the period preceding the installation of the tap, the grippers 122 can be left in place. When we want to install the valve, we remove the members 22 and connect offset fittings (not shown) on the tips 114 of the two fittings 110. We can then fix the fittings to said offset fittings.

Preferably, the nuts 130 remain in place because they contribute to the solidity of the fixing of the plate 102 against the partition 2. One could however imagine, as a variant, remove them.

Preferably, steps a) to f) are successive steps. However, one could very well imagine, as a variant, a different order. Typically, step a) could in theory be implemented after step b).

FIGS. 10 and 11 represent a second embodiment of a fixing kit 100. In this mode, the fittings 110 can be fixed independently at the front or at the rear of the plate 102. It suffices simply to provide that the diameter of the holes 3 made in the partition 2 is greater than the diameter of the flanges 116. Thus, in the case where the flange 116 of a connector 110 is fixed to the front face of the plate 102, the plate 102 can be fixed without space with the rear face of the plate 102 because the flange 116 is in fact pressed inside the corresponding hole 3.

Thus, it is understood that the recess 108 described above in connection with the first embodiment is purely optional.

Figures 12 and 13 show a third embodiment of a fixing kit 200. In the following, only the differences compared to the first two termination methods are mentioned. To facilitate understanding, the elements of kit 200 comparable to those of kit 100 have the same reference numeral, to which the value 100 is added.

Kit 200 differs from Kit 100 mainly by the nature of the fittings. Indeed, the kit 200 includes fittings 210 of the male type% allowing a direct connection of the taps, that is to say that the tap can be connected directly to the fittings 210, without using offset fittings, as in the first embodiment. In particular, the kit 200 is close to that described in FR 3,038,629 A1, the content of which is incorporated here by reference. Each connector 210 comprises a first connector 212 for connection to a pipe 4 and a second connector 214 for connection of the tap. The endpiece 214 defines a longitudinal axis X214, which also forms a central axis, and has an outer surface of polygonal section, in particular hexagonal. We are talking about a "hex" tip. Furthermore, the end piece 214 has an external thread.

Advantageously, the kit 200 comprises means for blocking the ends 214 in rotation about their axis X214. In the example, these means comprise a ring 215 for each connection end piece 214. Each ring 215 has an inner contour complementary to the external shape of the end piece 214, that is to say hexagonal. Each ring 215 is fixed to the plate 202 by screws 217. In particular, the screws 217 pass through holes provided in each ring 215 and come into engagement in corresponding threads provided in the plate 202.

Each end piece 214 is received inside a corresponding ring 215. The rings 215 block the rotation of the end pieces 214 about their longitudinal axis X214, but do not prevent them from sliding parallel to the axis X214.

Thus, the installer can adjust the length over which each endpiece 214 protrudes axially relative to the front face of the partition 2, as a function of the thickness of the wall covering, such as a tiling, intended to cover the partition 2. Typically, the thicker the tiling, the more the end pieces 214 should protrude relative to the partition 2.

The kit 200 also includes means for immobilizing each endpiece 214 along their longitudinal axis X214. In the example, these means are formed by two nuts 230 which, once the installer has reached the desired position, are screwed respectively around the end pieces 214, then screwed to the corresponding rings 215. In particular, screws 224 are used, which pass through holes provided in each nut 230 and which engage in threads provided in each ring 215.

If, however, the length over which the end pieces 214 must exceed relative to the partition 2 is not good and that the wall covering is installed, the installer can still unscrew the nuts 230 and pull or push axially on the end piece 214 , in order to adjust the length of the protruding end part.

The implementation of the assembly process with the kit 200 differs from that described previously on the following points.

In the kit 200, the plate 202, the fittings 210 and the anti-rotation rings 215 are delivered pre-assembled, that is to say that the rings 215 are already screwed to the plate 202. The nuts 230, themselves, are arranged separately.

Advantageously, the kit 200 also includes, for each fitting 210, a gripping member (not shown) capable of being removably fixed to the second end piece 214 of the fitting 210. Typically, each gripping member is screwed to the second connecting end piece 214 of a fitting 210, in particular around or inside a threaded hole of the second connecting piece 214. Preferably, each gripping member forms a tight plug, which is particularly practical for leak testing. As in the first embodiment, each gripping member has a cylindrical part for positioning a level, such as a spirit level. The gripping members are removed at the time of fitting the tap.

However, in this embodiment, the gripping members are optional, insofar as the threaded ends 214 themselves could serve as gripping members, since they are long enough to be caught by the installer and pulled out. through the holes in the partition 2. Nevertheless, the gripping members remain advantageous for carrying out the leakage tests.

For leveling the two fittings 210, the spirit level can be placed on a flat face of the end pieces 214.

The features of the embodiments and variants not shown can be combined together to generate new embodiments of the invention.
