Description
METHOD OF INSTALLING CONDUIT AND CONDUIT ASSEMBLY
THEREFOR.
This invention relates to the installation of conduit such as pipework and is particularly suitable for the installation of the plumbing required for central heating.
It is normal practice when installing pipework, especially that for central heating, in premises having wooden flooring, to install the bulk of the pipework for the central heating beneath the floorboards of the premises.
This has the virtue of minimising the amount of unsightly pipework which is visible upon completion of the installation.
This practice is convenient and easy when the premises are being constructed but is extremely disruptive when central heating is to be fitted to existing premises. Where premises have solid floors of concrete or similar material then, once again, during construction it is convenient to install pipework in channels provided for the pipework in the solid floors, but it is extremely disruptive to install pipework in this manner after a building has been completed.
The present invention seeks to provide a convenient way of installing conduit, such as pipework needed for a central heating system, in an existing building or premises with the minimum disruption to the structure, furnishings and decor of the premises, such that the conduit is hidden from view.
It is with a view to this end that the applicant invented the invention set out in European Patent Application No.EP0008544. The latter invention suffered certain drawbacks, one being that for neatness and compactness the pipework was of a rectangular section, but because of this it was difficult to pump fluid along the pipes due to their high flow resistance.
The present invention provides in one aspect a method of installing conduit comprising the steps of laying an open-topped channel section member on a floor adjacent at least one wall of a building; securing said member to the floor or wall; laying at least one conduit of smoothly continuous cross-section, for the conveyance of fluid, in said member; releasably fitting to said member a closure element to form an assembly which encloses the conduit within the said member; and laying floorcovering so as to abut said assembly to form a level floor surface.
Preferably the method also includes the additional step of laying said floor covering to overlie said closure element to form a level floor surface and to hide said assembly beneath the floorcovering.
It will be seen that by the invention the conduit pipe is hidden by the closure element and this is especially suitable for the installation of conduit for example across doorways, where the enclosed conduit is conveniently positioned so as to be beneath a door when the latter is in a closed position, in the manner of a conventional carpet gripping threshold strip. For conduit laid within a room of a building then the preferred additional step results in the conduit and closure element being hidden from view.
The invention also provides a conduit assembly for use in the method set out in the preceding paragraphs comprising an open-topped channel section member made from metallic material, a closure element therefor, also made from metallic material, and pipe conduit of smoothly continuous cross-section, the channel section member and closure element having formations by means of which they may releasably engaged with one another, to enclose the pipe conduit
Preferably the component parts of the assembly set out in the proceeding paragraph are supplied in standard lengths, lengths of each component being provided with inter-engaging means allowing one length to releasably engage a neighbouring length. Desirably the conduit assembly also comprises gripping means by which a portion of floorcovering can be secured to said assembly.
The assembly preferably also comprises, in order that the conduit may negotiate corners and bends and form junctions, at least one open-topped member, together with a complementary closure element, the open-topped member having inter-engaging means enabling said member to releasably engage at least two lengths of said channel section member such that said lengths do not have their longitudinal axes aligned, but such that said lengths and open-topped member have floor-abutting under-surfaces which are coplanar.
The assembly may mount a plurality of insulated electrical conducting elements. Means may provided for the insulated electrical connection of conducting elements of one length of channel section member and/or closure element with an adjacent element or with electrical components provided in a building within which the assembly is to be installed.
The conducting elements may be utilised to provide one or more power circuits such as 'ring' mains or for example spur lighting circuits, or control or supply circuits for domestic or other appliances. In another preferred aspect of the invention the pipe conduits may be replaced by the electrical conducting elements, such as cables, disposed on or in the assembly.
Preferably the conduit assembly comprises within the or each channel section member a separate region, walled off from a region in which said conduit is received, for the reception of at least one insulated electric cable comprising one or more insulated electrical conducting elements.
The open-topped element may be provided with a plurality of inter-engaging means so that it may be used in a variety of circumstances, also enabling 'T' and other junctions of lengths of said channel section member to be formed, or enabling a bend or corner selected from several choices of bend angle, to be made.
The open-topped element is preferably dimensioned such that it has preferably sufficient room inside to accommodate two portions of said pipe conduit side-by-side, the latter being either preformed at a chosen angular deviation or, where the pipe conduit is made of a flexible plastics material, there being sufficient room inside said open-topped element to allow the conduit to follow a smooth curve of the order of 10 centimetres radius within said open-topped element. Lengths of the plastics pipe conduit may be joined by the provision of ready-made push-fit joiners or alternatively the lengths may be formed with male and female formations at opposed ends for sealing engagement with complementary formations on adjacent lengths of pipe conduit.
The lengths of plastics pipe conduit may be sealingly joined by means of solvent or 'welding' procedures.
The or each conduit is preferably of rounded, flattened cross-section.
Where a conduit is required to emerge from said channel section member, for example to connect with a radiator, the pipe conduit is preferably provided with a portion of circular cross-section upstanding from the flattened cross-section pipe conduit said portion being received through an aperture of complementary shape provided in the closure element, said portion being compatible with conventional circular cross-section pipe for connection thereto in known manner.
The method of the invention and embodiments of assemblies according to the invention will now be described, by way of example only, and with reference to the accompanying drawings, in which:

Fig.8 is a schematic partial view of an additional assembly in accordance with the invention.
In the following description the various assemblies will be described first and then the method of the invention will be described in relation to the various assemblies.
In Fig.1 there is shown an assembly having an open-topped channel section member 10 dimensioned to receive a pair of conduits 12 each of flattened, rounded cross-section. The member 10 comprises a web 14 with upstanding walls 16 at outer margins of the walls and centrally disposed upstanding dividing walls 18. The walls 16 are provided with elongate socket formations 20. An elongate closure element 22 comprises a cover portion 24 having at its outer margins elongate lip formations 26 releasably engageable in the sockets 20 in an interference fit, to enclose conduits 12 in the assembly. The closure element 22 is provided along one of its long sides with an elongate socket 30 open to the side for receiving an edge portion 28 of a carpet.Upstanding teeth 32 are provided within the socket and so disposed to engagingly grip said carpet and restrain withdrawal of the carpet edge portion 28 from said socket 30. The walls 18 are provided for additional support of the closure element 22.
The assemblies shown in Figs 2-6 have many similarities to that shown in Fig.1 and corresponding reference numerals have been used to indicate similar portions of the assemblies. In the assembly shown in Fig.2, it will be noted however that two sockets 30 are provided along opposed long sides of the assembly but they form part of the open-topped channel section 10 and not the closure element 22. In Fig.2 the pipe conduits are not shown. This assembly is useful where a conduit is required to cross a doorway, the assembly being laid so as to be disposed beneath a door of the doorway when the door is in a closed position (in the manner of a conventional threshold strip carpet gripper). Carpet to each side of the doorway is received in an appropriate socket 30.It will be seen that in the assembles of Figs. 1 and 2 the carpet 28 does not overlie the closure element 22, which is thus visible but of neat appearance and readily accessible, especially in the assembly shown in Fig.2.
In the assembly shown in Fig.3, the closure element 22 has upstanding teeth 40 to grip carpet 42 disposed in use to overlie the entire assembly. This is a desired assembly where frequent access is not a requirement and appearance is important. Carpet 42 also overlies conventional underlay 43 lying alongside member 10.
The assembly shown in Fig.4 is essentially the same as that shown in Fig.3 except that during installation a small gap 43 is left between the open-topped channel section member 10 and a wall 44 so that an edge 45 of carpet 42 can be received in the gap to provide a neat finish.
In the assembly shown in Fig.5 the closure element 22 is again provided with upstanding teeth 40 to grip a portion of carpet 42 which overlies the assembly. Further, the closure element 22 is provided with a flange 47 with an outturned portion 48 disposed so as to overlie the floor of a room in which the assembly is installed. The portion 48 may be secured to said floor with tacks or screws, for additional security against movement. In the assembly shown in Fig.6 there is shown an open-topped channel section member of the kind shown in Fig.3, and a corresponding closure element provided with an aperture 22a of round shape. The assembly is shown with the channel member abutting a skirting board 52 of a room wall 54, secured to a floor 56 and in the channel member there are disposed a pair of conduit pipes 12a, 12b.
one conduit pipe 12a is provided with an upstanding portion 57 of circular cross section received through aperture 22a and cooperable in known manner with a copper pipe 58 connected to a radiator 60 through a valve 62. The conduit pipe 12a does not continue past the pipe 58 along the channel member. The pipe 12b continues along channel member until it connects with a further pipe (not shown) similar to pipe 58 but connected to an opposite end (not shown) of radiator 60.
thus fluid is conveyed from conduit pipe 12a into the radiator, through the radiator, and into conduit pipe 12b
In the assembly shown in part in Fig.7 the channel section member 10 is provided with an extra channel 70 walled off by an additional wall 18a from the channels which receive conduits 12. The channel 70 receives, in use, at least one electric cable 72a, 72b for the supply of mains electricity and/or one or more telephone cables 74. The cables 72a, 72b, 74 emerge where necessary to connect with appliances and power installations through apertures cut where required in the side wall 16a of the channel 70. A complementary closure element (not shown) similar to those shown in previous figures is provided to enclose the cables and conduits.
In the embodiment of Fig.8 there is shown an open topped member 80 provided with a closure element of complementary shape (not shown) the open topped member being arranged so as to link up with two of the assemblies shown in Fig.5 having their axes arranged at right angles in order that conduits 12 may negotiate a corner. Lugs 82 are provided to locate between walls 18 in the embodiment of Fig. 2 such that the undersides of the assemblies and open topped member shall be coplanar. It is to be understood that angles other than the right angle shown in Fig. 8 may be negotiated using open topped members of appropriate shape.
The closure member of the channel section member may actually mount electrical conductors, suitably insulated, the conductors for example being applied by 'printed circuit' technology. This is however not preferred as there are problems of ensuring good electrical connections and completeness of insulation at joints of the enclosure member and/or channel section member.
It will be appreciated that the height of the assembly is substantially equal to the thickness of a conventional carpet or carpet underlay so that the assembly may abut the carpet when the assembly is to be visible or abut a carpet underlay so that carpet can overlie both underlay and the assembly when the latter is to be invisible.
It will be readily apparent from the foregoing description how the method of the invention may be performed.
The open channel section member is positioned on a floor adjacent a wall and the member secured to the wall through web 14 or a side wall 16 by pins, nails, screws or adhesive.
he fluid tight conduit(s) is/are then laid in the channel section member and a closure element(s) fitted on to the channel section member to enclose the conduit(s). The closure element(s) may then, where appropriate, (Fig.5) also be secured to the floor. Carpet is then secured to the resulting assembly by the gripping means. Cables are laid where appropriate alongside the conduits (Fig.7) before fitting the closure element(s). Cables and conduits emerge to link up with circuits and pipework in the manner shown in
Figs. 6 and 7.
Various modifications and improvements may be made within the scope of the invention.
The invention possesses the advantage that in making fluid-tight pipe conduit connections, such connections may well be unsightly though mechanically sound. With the present invention such unsightly connections are hidden from view.
