Description
CLADDING APPARATUS AND XHTKOD This invention relates to an apparatus for, and a method of, cladding for use in the insulation industry.
Presently, a member to be cladded with insulation, such as pipework, is cladded with the insulation, and subsequently an outermost protective cladding layer positioned and retained on the outer surface of the insulation layer. The outermost protective cladding layer comprises a plurality of swedges, ie. suitably shaped sheet form members, which are retained around the insulation layer by means of a plurality of self tapping screws or the like. Each swedge is further retained in association with adjacent swedges by means of respective raised and depressed portions located adjacent respective outermost edges of each swedges, each portion being engageable with a corresponding portion on the adjacent swedge. In this way the swedges can be used to build up a complete outermost protective cladding layer on the insulation layer, including at bends, junctions etc.
A problem exists in this type of prior outermost protective cladding in that the installation of such cladding is time consuming and labour intensive.
A further problems exists in that periodic inspection of the insulation and cladding is required - this being carried out by the PID (Plant Inspection Department). Since such inspection involves the removal, and reassembly, of the cladding layer, this is again expensive and labour intensive.
It is, therefore, an object of the present invention to obviate or mitigate the aforementioned disadvantages.
Further advantages, of at least some embodiments of the present invention, are as follows:
removal of the need for self tapping screws and
washers;
no need for the use of drills, or power tools on
site, and, therefore, no need for plant or
equipment;
no need for a "Hot Work Permit", since no drilling
needed.
Accordingly, a first aspect of the present invention provides a cladding layer member comprising a sheet form member suitably shaped such that first and second opposing edges thereof substantially meet one another so as to enclose a member locatable therewithin, the opposing edges being capable of being held in association with one another by means of a clip, first and second portions of which are located adjacent respective opposing edges.
Hereinafter, the term "clip" is used in the sense of "releasibly engageable retaining means".
According to a second aspect of the present invention there is provided a cladding layer member comprising a plurality of sheet form members suitably shaped such that respective first and second edges of adjacent sheet form members can substantially meet one another so that the plurality of sheet form members enclose a member locatable therewithin, each pair of respective edges being capable of being held in association with one another by means of a clip, first and second portions of each clip being located adjacent respective first and second edges.
The clip can be a toggle type clip.
More than one clip can be provided to hold the first and second edges in association with one another, first and second portions of each clip being located adjacent respective first and second edges.
Either of the opposing first and second edges can be formed into the shape of an 'S', the other edge being insertable within the portion of the 'S' shaped edge which is concave with respect to the other edge.
The 'S' shape formed on one of the edges is preferably oriented inwardly of the cladding layer.
The 'S' shaped edge may be formed with the 'S' having an extended tail, so as to ease in the locating of the other edge within the concave portion of the 'S' shaped edge.
Each sheet form member may itself comprise a plurality of preassembled sheet form members positioned longitudinally of one another, the meeting edges of which are held in association with one another by means of rivets, welds or even further clips.
In this case, all, or only some, of the sheet form members can have first and second portions of a clip or clips located adjacent respective first and second edges thereof.
A strengthening member may further be provided which is attached to and bridges two or more of the plurality of preassembled sheet form members.
In most applications the sheet form members will be made of metal, particularly one of aluzinc, aludip, aluminium, stainless steel, or a galvanised metal. However, it should be appreciated that other materials could be used for other applications.
According to a third aspect of the present invention there is provided a method of cladding a member comprising enclosing the member within a cladding layer member comprising a suitably shaped sheet form member, first and second opposing edges of which substantially meet one another and are capable of being held in association with one another by means of a clip, first and second portions of the clip being located adjacent respective opposing edges.
According to a fourth aspect of the present invention there is provided a method of cladding a member comprising enclosing the member within a cladding layer comprising a plurality of suitably shaped sheet form members, respective first and second edges of adjacent sheet form members substantially meeting one another and being capable of being held in association with one another by means of a clip, first and second portions of which are located adjacent respective first and second edges.

Referring to Figs 1, 2 and 3 there is provided a first embodiment of a longitudinal cladding layer member, generally designated 5a, according to the present invention. The cladding layer member 5a comprises a sheet form member 10a having a substantially cylindrical cross-section. First and second opposing longitudinal edges 15a, 20a thereof substantially meet one another so that the cladding layer member 5a encloses a space therewithin.
The opposing longitudinal edges 15a, 20a can be held in association with one another by means of releasibly engageable retaining means, in the form of toggle clips 25a, 30a, first and second portions 35a, 40a of each of the clips 25a, 30a being provided adjacent opposing longitudinal edges l5a, 20a.
The first portion 35a (not shown in detail) of each clip 25a, 30a comprises a plate member 45a which may be attached adjacent the first edge 15a by means of rivets, welds or the like. On the plate member 45a is an upwardly protruding member 15a having a lug 55a at the upper end thereof which faces away from the second edge 20a.
The second portion 40a (not shown in detail) of each clip 25a, 30a comprises a further plate member 60a which may be attached adjacent the second edge 20a by means of rivets, welds or the like. On the plate member 60a is substantially rectangular frame member 65a, one edge of which is pivotally connected to the further plate member 60a.
One of the edges 15a is further formed into the shape of an 'S' oriented inwardly of the cladding layer member 5a. In this way edge 20a can be inserted within a portion of the 'S' shaped edge 15a which is concave with respect to the edge 20a.
In use, an installer will clad a pipeline (not shown) with insulation material (not shown), and then install the longitudinal cladding layer member 5a over and around both, firstly by ensuring that the clips 25a, 30a are loose, and then prising the first and second edges 15a, 20a apart. In this way the cladding layer member 5a can be placed around a member to be cladded - in this case the pipeline cladded with insulation.
The installer can then align the edges 15a, 20a, and thence insert the edge 20a into the concave portion of the other edge 15a.
The rectangular frame member of the second protion 40a, can then be placed over the lug 65a, 55a and upwardly protuding member 50a of the first portion 35a, and the two portions 35a, 40a releasably engaged with one another, as is conventional with toggle type clips.
If and when inspection of the pipeline or insulation is required, the cladding layer member 5a can readily be removed by releasing the clips 25a, 30a.
Referring to Figs 4, 5 and 6 there is provided a second embodiment of a longitudinal cladding layer member, generally designated 5b, according to the present invention. The cladding layer member 5b comprises two sheet form members lOb, llb of substantially semi-circular cross-section. The two sheet form members lOb, llb can be arranged such that respective longitudinal first and second edges 15a, 16a, 20a, 21a meet one another so that the cladding layer member 5b encloses a space therewithin.
The respective longitudinal edges 15a, 16a, 20a, 21a held in association with one another by means of releasibly engageable retaining means, in the form of toggle clips 25b, 30b, first and second portions 35b, 40b of each of the clips 25b, 30b being provided adjacent respective longitudinal edges 15b, 16b, 20b, 21b.
The installation of the cladding layer member 5b is apparent in view of the foregoing description of the installation of cladding layer member 5a. It should, however, be noted that when installing cladding layer member 5b, an installer may choose to either locate both sheet form members lOb, lib in place, and then clip them together, or alternatively clip one pair of edges together, eg. first and second edges 15b and 20b, and then place the cladding layer member Sb over the member to be clad in an analogous way to installing cladding layer member Sa.
Referring to Figs 7 and 8 there is provided a first embodiment of a radius bend cladding layer member, generally designated 5c, which comprises two semi-circular sheet form members lOc, llc. The construction and installation of the radius bend cladding layer member 5c is analogous to the longitudinal member 5b, and therefore needs no further explanation.
Referring to Figs 9, 10, 11 and 12 there is provided a second embodiment of a radius bend cladding layer member, generally designated 5d. The difference between this embodiment, and the first embodiment of the radius bend 5c, is that herein, the sheet form members lOd, lld comprise a plurality of preassembled sheet form members (in this case five, 70d, 75d, 80d, 8Sd, 90d and 95d, lOOd, 105d, 110d, 115d respectively) positioned longitudinally from one another, and held in association, in this case, by rivets.
First and second portions 35d, 40d of clips 15d, 20d are only provided on the first and fifth sheet form members 70d, 90d and 95d, 115d respectively. It should, however, be understood that clips could also be provided on the other members 75d, 80d, 85d if required.
Strengthening members 120d, and 125d are further provided on the inner surfaces of the sheet form members lOd and lld respectively, bridging, and attached to, each of the preassembled sheet form members, 70d, 75d, 80d, 85d, 90d and 9Sd, lOOd, 105, 110d, 115d respectively. The purpose of the strengthening members is to both strengthen the members lOd and lld, and also aid in retaining the preassembled sheet form members 70d, 75d, 80d, 85d, 90d and 95d, lOOd, 105d, 110d, 115d together.
Referring to Figs 13, 14 and 15 there is provided first and second embodiments of elbow bend cladding layer members, generally designated 5e and 5f.
Referring to Figs 16 and 17 and to Figs 18 and 19 there is provided first and second embodiments of T-junction cladding layer members, generally designated 5g and 5h.
Referring to Figs 20 and 21 there is provided first and second embodiments of conical cladding layer members, generally designated 5i and 5j.
The construction and installation of the embodiments of
Figs 13 to 21 need no further description since this is apparent from the description of the previous embodiments.
Finally, it should be appreciated that the embodiments of the present invention hereinbefore described are given by way of example only, and are in no way meant to limit the scope of the invention.
