Description

FIELD OF THE INVENTION

The invention relates to a sealing apparatus which can be used in the field of building construction, and in particular for fixing plumbing elements.

PRIOR ART

Sealant sealing is a common technique in building construction. Hydraulic setting material such as plaster or prompt cement is used, for example, to partially coat the sealer and bond it to the masonry. In the field of plumbing, the trend is to integrate the pipes in the walls or floors so that they are not visible. In the case of domestic water pipes, these are connected to taps, for example a tap projecting from a vertical wall. A hydraulic heating network using radiators is also formed in the same way.

For the connection of the fittings to the pipes, a pipe-shaped connection is generally placed which is welded or crimped at the end of the pipe. The fitting has a threaded female outlet which is placed opening perpendicular to the wall, as shown in FIG. figure 6 . The fitting is sealed in the wall in order to properly maintain the faucet. The fitting is then secured via a threaded nipple which is screwed into the outlet of the fitting. In the case of a tap with an inlet for cold water and an inlet for hot water, two supply lines and two connections are provided. The distance between the connections is normalized, for example to 150 mm, and the position of the fittings must meet this condition to allow mounting. In addition, it is necessary that the axes of the threaded portions of the connections are parallel to each other, perpendicular to the wall and that the fittings are flush in the same plane.

The method of laying these connections is generally to make a groove in the wall, coat the bottom of the groove with the quick-setting material, set up the pipes and fittings before setting, finish coating the bleeding in coating especially the fittings and hold them in place until the setting of the material.

It is obvious that it is very difficult to obtain a good positioning of the connections during the setting. Indeed, the pipes have a high elasticity and tend to put the fittings in a position that is not necessarily the desired one. In addition, at least one operator is mobilized until the catch is obtained.

The document EP 1 178 257 shows a device intended to be used on plasterboard in particular. The device comprises a metal plate intended to be fixed on the plasterboard wall, at the arrival of the pipes. The metal plate has at least two holes, and fittings are provided to be fixed through the holes and held by a nut screwed from the outside. This device has the disadvantage that the metal plate protrudes from the surface of the wall. It also requires the use of special dowels for fixing the metal plate to the wall. Moreover, this additional element remains in place and is for single use. This solution is not well suited to cases of solid walls.

The document EP 1 253 386 shows a template of mounting for plastic pipes supplying a radiator. A square serves as a support and is first attached to a wall. Then, a ruler with two guides receives two pipes in the guides and is screwed on the square. The sealing of the pipes can then be carried out. This equipment is not suitable for fixing fittings for faucets.

OBJECTIVES OF THE INVENTION

The invention aims to provide a sealing apparatus for sealing elements, in particular for plumbing elements, which allows to obtain precisely the position of the elements to be sealed with ease of implementation.

STATEMENT OF THE INVENTION

With these objectives in view, the invention relates to an apparatus for sealing at least one element to be sealed, comprising a support and connecting means for fixing the element to the support, the connecting means comprising a first member intended to to receive the element to be sealed, characterized in that the connecting means further comprise a second member connected to the support, the second member being connected to the support or to the first member by magnetization in an adjustable manner.

Providing magnetization connection means, it is easily possible to obtain a relative adjustment between two members or with the support, by sliding the two members one on the other or on the support. The position obtained is maintained by the attraction of the limbs or the support between them. Once the adjustment is obtained, and thus the position of the determined sealing element, the sealing element can be coated with sealing material while the position of the sealing element is maintained.

According to one particular provision, the second member has two wings perpendicular to each other, the first receives the first member connected thereto by magnetization, the second member being connected to the support by magnetization between the support and the second wing. Thus, it is possible to obtain adjustments in directions and directions which intersect and which are complementary, in order to have the maximum of adjustment possibilities.

The first wing of the second member has for example a flat face. The first member which is placed on this plane face can be adjusted in distance in all directions of the plane of the wing, and in rotation along an axis perpendicular to the plane. The position is therefore adjustable according to three degrees of freedom.

According to another feature, the first wing of the second member has a face having at least one stopper to define a predetermined orientation of the first member when it is in abutment against the stopper. The cleat allows to predetermine a direction of the first member relative to the support. If the support is oriented relative to the wall to be equipped, the direction of the element to be sealed can be obtained directly. Moreover, by combining assemblies to hold two elements to be sealed at the same time, on the same support, it is possible to predefine, with cleats, a spacing and a parallelism between the axes of two elements to be sealed.

According to another provision, the first member is slidably mounted on the second member, locking means for maintaining a relative position of the members together. The connection is not obtained in this case by magnetization, but by the locking means. Guiding the second member provides a preset permanent direction between the first and second members.

In a particular way, the support comprises least one face of magnetic material, the connecting means comprising a permanent magnet for cooperating with the magnetic material side. Thus, the permanent magnet of the connecting means can be placed over the entire length of the support. It is not necessary to provide a large magnet on the support. The magnetic material is, for example, mild steel. The face may be a sheet attached to the support. It can also be directly a wall of a rectangular metal tube forming the support or a part thereof.

According to an improvement, the support comprises two parallel guiding faces between them to guide the second member between the guide faces. Thus the second member is guided between the guide faces to always remain centered on the face of magnetic material.

In a complementary manner, the second member comprises a disc-shaped foot whose dimensions are adapted to the width between the guide faces of the support, the foot being in abutment on the face of magnetic material. Thus the second member is guided in one direction along the guide faces, but is free to pivot about an axis perpendicular to the face of magnetic material.

In a complementary manner, the first member comprises a spirit level. It is thus possible to adjust easily without additional instrument the horizontality of the axis of the element to be sealed.

In the case of use in plumbing, the first member comprises a part to be screwed on the element to be sealed, the workpiece being fixed separably on the first member. The part to be screwed makes it possible to fix the element to be sealed by a functional part which then determines the orientation of the elements which will be fixed there. The maintenance is also well assured by this means. As the workpiece is separable, it can be connected first to the element to be sealed, then connected quickly to the first member.

According to an improvement, the support comprises a base for resting on the ground and an amount disposed between the base and the connecting means. The device does not need to be fixed and its stability is ensured by the base. This also has the advantage of allowing the device to be removed after the adjustments have been made, to put the sealing material in place and then to put the assembly back in place, if the precaution has been taken to accurately locate the position of the apparatus on the ground, for example by means of stops.

According to a particular provision, the amount is telescopic. It is thus possible to obtain a large range of use over the height, while limiting the size of the apparatus, in particular for storage or transport.

According to another arrangement, the amount is removably mounted or articulated on the base. This facilitates the transport of the device by limiting its size. In addition it is thus possible to give the amount of various positions relative to the base, to provide a multiplicity of positions amount and diversified use of the device.

According to another improvement, at least one of the members is graduated. It is thus easy to locate his position.

DETAILED DESCRIPTION

A sealing apparatus 1 according to a first embodiment of the invention, as shown on the Figures 1 to 5 , comprises a support 10 comprising a base 101 intended to rest on the ground. The support 10 further comprises a telescopic upright 102 extending substantially vertically from the base 101 when the latter rests on the ground. The post 102 is located near an edge of the base 101 so that the post 102 can be placed in close proximity to a wall. The amount 102 is telescopic in order to adjust its length. For this, it comprises two tubes 1021, 1022 of rectangular section which is enclosed in one another. The tubes are made of mild steel. Stop means 103 are provided to hold the two tubes 1021, 1022 in a more or less extended position. These stop means 103 are represented by a pressure screw, but other equivalent techniques could be used.

The sealing apparatus 1 further comprises connecting means for attaching to the support 10 two elements to be sealed 2. In the example shown, the elements to be sealed are pipe-shaped connectors 2 connected at one end to pipes 3 flexible plastics such as PER. The pipes 3 extend in a groove 4 of the wall 5 and are intended to be embedded in the sealing material. Each connector 2 comprises a female threaded outlet 20 whose axis is substantially perpendicular to the direction of the pipe 3 and the wall 5, as shown in FIG. figure 6 .

The connection means comprise two sets, each set comprising a first member 12 intended to receive the element to be sealed 2 and a second member 13 connected to the support 10 and making the intermediate between the first member 12 and the support 10. The first and the second member 12, 13 are interconnected by magnetization in an adjustable manner, as well as the second member 13 and the support 10.

The second member 13 has a tee shape with two wings 131, 132 perpendicular to each other. The length of the second member 13 substantially corresponds to the width of the amount 102. The first flange 131 receives the first member 12, while the second flange 132 is pressed against the amount 102 by the magnetization. For this, as best shown by the figure 2 the second flange 132 comprises a plate-shaped magnet 1320 which is screwed to the second member 13.

The first wing 131 has a flat face 1310 and an opposite face 1311 to the flat face having tabs 1312 parallel to the second wing 132. It is made of mild steel to be magnetic.

The first member 12 is formed by a tube 122 fixed on a rule 121. The rule 121 comprises a magnet of flat shape and having two edges 1210 parallel to the axis of the tube 122. The first member 12 can be placed on the first flange 131, against the face 1311 with cleats 1312, one of the edges 1210 of the magnet being in abutment against one of the cleats 1312. The axis of the tube 122 is then in a predefined direction relative to the support 10, and at a predefined distance. The tube 122 is threaded at its end and receives a workpiece 123, held by a collet nut 124. The screw part 123 also has a male thread adapted so that the screw part 123 can be screwed into the connection 2 to seal. The first member 12 also includes a spirit level 125 to facilitate adjustment operations.

When using the sealing apparatus 1, as shown on the figure 1 , the support 10 is placed opposite the place where the connections 2 to be sealed must be, for example for the connection of a shower valve. A distance from the floor and the angle of the wall 5 should preferably be respected. The screw pieces 123 are placed on the outlets 20 of the connections 2 to be sealed, and then the screw pieces 123 are fixed to the tubes 122 of the first members 12 by means of the collar nuts 124.

Then, adjusting the position of the first members 12 on the second members 13 and second members 13 on the support 10 until the desired position and orientation of the connectors 2 to seal with respect to the wall 5 and between them. The adjustments are made by sliding the second flange 132 on the support 10 or the first members 12 on the first flange 131. The position obtained is maintained by the adhesion between the surfaces due to the attraction exerted by the magnets. The kerf 4 is then filled with a material to be sealed so as to coat the pipes 3 and the connectors 2. The sealing apparatus 1 makes it possible to maintain the correct position of the connectors 2 during the setting and setting of the sealing material, without the presence of an operator. When the grip is made, the flanged nuts 124 are loosened so as to separate the first members 12 of the parts to be screwed 123, the support 10 is removed and the parts to be screwed 123 are unscrewed.

We showed on the figure 5 another configuration of use of the sealing apparatus 1 for fixing connectors 2 for supplying a radiator through connections located one above the other. The two sets of connecting means are placed on the same face of the support 10 at different heights. The settings are made in the same way as before.

The sealing apparatus 1 can be used by placing the first members 12 on the face having cleats 1312, the magnet being supported by one of its edges against a cleat 1312. It is thus possible to obtain positions in which the first members 12 are parallel with a predetermined spacing, for example 150 mm. By sliding the first member 12 along the cleat 1312, it is still possible to adjust the depth of depression of the connector 2 in the groove 4 of the wall 5. It is also possible to use the sealing apparatus 1 by directly placing the first member 12 on the amount 102. The amount 102 then plays the role of the second member 13.

In a second embodiment, as shown in the Figures 7 to 11 , the base 101 'comprises a base 1010 on which two crosspieces 1011 are mounted sliding transversely to the base 1010. The base 1010 further comprises two flanges 1012 between which the amount 102' is inserted and tightened by clamping means 1013 to be Removably attached. Other clamping means 1014 are provided for stopping the sleepers 1011. The ends of the sleepers 1011 are equipped with soft 1015 buffers.

The amount 102 'has two grooves 1023 parallel to each other and extending over the entire length of the amount 102'. Each groove 1023 is delimited by guide faces 1024 while the bottom is lined with a metal sheet 1025 forming the face of magnetic material. The second member 13 'has a disk-shaped foot 133 whose diameter is adjusted to the width of the groove 1023. Thus, the transverse position of the second member 13' is determined by the guide faces 1024 which position the foot 133. However, the foot 133 can pivot between the guide faces 1024.

The second member 13 'is shown in detail on the figure 11 . It comprises a magnet 136 placed in the center of the disk so as to act on the surface thereof. A wing 132 'protrudes from the foot 133 and has two cylindrical housings 1325 parallel to each other and to the face of the foot 133. One of the housing 1325 to choose the first member 12' which has a tubular shape. The first member 12 'can thus slide in the housing to adjust its position. The second member 13 'further comprises locking means 134 for fixing the first member 12'. The locking means 134 comprise a wedge 1340 slidably mounted in a recess 1341 tangential to the two housings 1325 and a screw 1342 exerting traction on the corner 1340 to press against the first member 12 '. The second member further comprises a spirit level 1326 at the end of the wing 132 '.

In use, the second member 13 'can be adjusted in position in the longitudinal direction of the upright 102' and in orientation along an axis perpendicular to the faces of magnetic material, the magnet 136 maintaining the position obtained by sliding or by removal and pose. The first member 12 ' can be positioned relative to the second member 13 ', in principle in a direction transverse to the amount 102'. Several linking assemblies 12 ', 13' can be used, as shown on the Figures 7 to 10 .

The figure 8 shows that it is possible to move the sleepers 1011 to the left in order to place the amount 102 'closer to a wall angle to the right. Similarly, figure 9 shows that it is possible to move the sleepers 1011 to the right in order to place the upright 102 'as close to a wall angle to the left. The figure 10 shows also a use of the apparatus 1 'in which the amount 102' is placed horizontally between the flanges 1012 to place the first members 12 'in a vertical axis cantilever relative to the base 101'. It is also possible to use two bases 101 'connected by the amount 102' acting as a beam, the faces of magnetic material being placed horizontally or vertically. In this first case, the cross members 1011 make it possible to adjust the altitude of the beam.

The invention is not limited to the embodiments which have just been described by way of example. The tube of large section of the telescopic post could be in the upper part while the tube of smaller section could be fixed on the base.
