Description
IMPROVEMENTS TO MEMBRANE LINED GUTTERS
The present invention relates to an improved membrane lined gutter. The primary purpose of a gutter is to collect and contain water running off an adjoining roof-slope and to direct it to disposal points.
Lightweight and flexible materials are used in gutter manufacture but these materials can have associated problems of leakage, instability and corrosion. Most commonly used, metal based, lightweight gutter systems are subject to one or more of these problems.
Although gutters can be manufactured from aluminium, glass reinforced plastics (G. R. P) materials and other suitable materials, the most preferred material is a 2mm-3mm thickness steel substrate with a pre or post galvanised coating. Steel is the most preferred material owing to
, -, availability, speed of manufacture and cost and 2mm thickness steel is the most predominant thickness.
Although steel has excellent strength to weight characteristics and 2mmthickness steel will support loads, for example from foot traffic, without undue deflection, it has an unreliable life span owing to the erosion of its galvanised coating and the subsequent corrosion of the steel substrate.
This erosion and corrosion process can take from as little as 12 months to 15 years to occur depending on a large variety of circumstances.
Measures have been taken to slow or prevent this process by the application of protective paints and to a certain extent these have been successful. However there is a significant price increase for a suitable coating.
In use sections of gutter must be joined together and the most common joint comprises the use of Polyisobutylene synthetic rubber mastic (P. I. B) in strip form within a bolted joggle and spigot joint. Although
Polyisobutylene can provide an effective seal for a considerable length of time it is fairly common for the joint to fail.
The above problems have been addressed to some extent by the provision of membrane lined gutters wherein roofing membranes are applied to gutters as the waterproofing medium. The membrane is applied to a suitable substrate, for example steel, and gutter sections are joined using existing membrane joint technology to form a homogenous lining. The resultant product is long term, leak free and able to withstand structural movement and corrosion.
The problem with membrane lined gutters is that they are inherently expensive and because of the increased costs are rarely used for"single skin"gutters but are more often used in insulated gutter systems.
Furthermore the membrane is usually bonded to steel approximately 0. 7mm thick to keep costs to a minimum and is then fabricated into a composite unit, which includes a rigid insulation board and a decorative steel lining tray, again of 0. 7mm thickness. The component parts are usually bonded together and make a rigid assembly when complete.
To date no steel having a thickness of less than 2mm has been deemed to have the required structural integrity to support the imposed loading for single skin gutters. Therefore the 0. 7mm thickness steel used in membrane lined gutters would be inadequate for single skin gutters other than for the smallest of gutters which would not be required to support foot traffic of any kind.
The aim of the present invention is therefore to develop a composite material comprising a membrane and a"thin gauge"material that has good inherent waterproofing qualities and the structural capabilities similar to 2mm thickness galvanised steel while keeping the costs to a minimum.
Accordingly the present invention provides a composite material including a membrane secured to a substrate comprising a rigidised material.
The membrane is preferably a waterproof membrane and may, for example be a polypropylene alloy, a flexible PVC alloy, a polyethylene alloy, EPDM (ethylene propylene diene monomer) or polyisobutylene (P. I. B.).
The rigidised material is preferably a rigidised metal, most preferably steel. The steel preferably has a thickness of less than or equal to 1.4mm
The membrane and rigidised materials are preferably bonded together using an adhesive. Suitable adhesives include moisture cured or solvent/moisture-cured polyurethanes or contact adhesives. The adhesive may alternatively be a polyester resin based adhesive, preferably the resin based adhesive is a solvent borne formulation. The resin based adhesive is preferably heat cured. The type of adhesive used depends on the bonding process that may, for example be continuous or blank bonding.
The membrane preferably includes a fleece secured to its underside. The fleece is preferably synthetic and may be secured to the membrane during membrane manufacture by means of a permanent adhesive. The fleece provides a suitable medium to aid secure bonding of the membrane to the rigidised material and allows a large variety of adhesives to be used.
The present invention also provides a gutter section formed from the composite material of the present invention.
Gutter sections formed from the composite material of the present invention are lightweight owing to the reduction in the amount of substrate by the use of a rigidised material. The reduction in weight allows longer gutter sections to be supplied thus reducing the number of joints needed.
The gutter section of the present invention has a strength and rigidity comparable to gutter sections made from 2mm thickness steel and can therefore be used in"single skin"gutters where membrane lined gutter sections were not previously acceptable.
The gutter sections of the present invention may be joined together to form a gutter system. The use of butt straps and rivets may join the sections, alternatively male-female clips may be used.
The joints are then sealed, preferably using a patch of the membrane that is heat-sealed over the joint to make it waterproof.
The composite material of the present invention can also be used to manufacture accessories for gutter systems, for example, outlet pipes.
The present invention will now be described in more detail with reference to the figures in which:
Figure 1 shows a first embodiment of the composite material of the present invention ; and
Figure 2 shows a second embodiment of the composite material of the present invention ; and Figure 3 shows a rigidising pattern applied to the composite material of the present invention.
The composite material 1 of Figure 1 is manufactured from a flexible polypropylene alloy membrane 2 securely bonded to galvanised steel 3 with a gauge thickness no greater than 1. 4mm.
The adhesive used to bond the membrane 2 to the steel 3 is a single component, solvent borne formulation based on a polyester resin. The adhesive is applied to the steel 3 by means of a roller. The steel 3 is then passed, by a conveyor, through an oven and heated to 1600. The solvent is flashed off by this heat and on emergence from the oven the membrane 2 is applied in continuous form to the steel 3 and then passed through "pinch"rollers to consolidate the bond. At the same time the composite material 1 is cooled by air or water or a combination of both.
The bonding process can be carried out in a number of ways with the most appropriate being :a) Continuous method (as described in relation to Figure 1)-the materials are bonded continuously from separate rolls with adhesive being introduced prior to application of pressure to form the bond. The resultant material may be either blanked into sheets or re-coiled for further processing ; or b) Blank method-the composite material is formed from individual sheets of membrane and galvanised steel. Adhesive is applied to either
the steel or the membrane or to both and a stack formed from several sheets, which is then be pressed to form the bond.
The resultant composite material does not have sufficient strength and rigidity to approach that of 2mm thickness galvanised steel so a rigidising process is applied to the composite material.
The rigidising process forms ribs 4 along the length of the material 1, which form the pattern shown in Figure 3 and provide structural strength and improved rigidity.
Where the composite material is in sheet form the sheet is passed through a set of powered rolls. One roll is directly above the other (pinch roll format) and they are of sufficient width to allow the complete width of a sheet to pass through. The rolls are machined in rib format around the diameter and the ribs are formed so that the ribs of the top roll mate with the ribs of the bottom roll. The spacing between the rolls is adjustable to allow sufficient spacing between them such that when the sheet is passed through the ribbed form from the rolls is transferred to the entire length of the sheet to the required depth of profile.
Where the composite material is in a coil the coil is loaded onto a decoiling mandrell located behind the powered rolls and as the composite material is de-coiled it is passed through the rolls and the either cut into sheets or re-coiled.
The composite material 10 of Figure 2 is manufactured from a flexible polypropylene alloy membrane 11 with a synthetic polyester fleece 12 applied to the underside at the initial membrane manufacturing stage.
The fleece 12 is permanently bonded to the underside of the membrane 11 by an adhesive.
The fleece 12 provides a medium for securely bonding the alloy membrane 11 to galvanised steel 13 with a gauge thickness no greater than 1.2mm.
Due to the versatility of both the fleece 12 and galvanised steel 13 surfaces the two materials may be bonded together using a variety of adhesives, the nature of the adhesive being dependant on the bonding process used. Appropriate adhesives include moisture cured or solvent/moisture cured polyurethanes or alternatively contact adhesives may be employed.
The composite material 10 is subjected to a rigidising process as described above in relation to Figure 1.
Forming and fabrication method
The resultant material may be press formed into any gutter using traditional metalwork techniques, membrane fabrication methods or plastics welding technique or a combination of all three.
Typical fabrication methods employed for the manufacture of accessories would be press joining, flanging, rolling (e. g. into cylinders for outlets etc. ).
Typical membrane techniques employed would be hot air welding and forming to weather and seal corners and fabrication joints using strip membrane or formed membrane accessories. Hot air welding can be used to melt"rods"of material identical to the membrane composition to fill areas that are difficult to seal by the other methods.
Site Application The composite material gutters of the present invention are fitted in similar ways to existing gutters, for example they are supported by brackets or wrapped over and attached to the eaves purlins.
The composite gutters are easier and faster to fit than traditional systems as they are approximately 30% lighter in weight. This decrease in weight, together with processing from coiled materials provides the opportunity to offer far longer length gutters than can normally be provided and the further opportunity of site forming which would eliminate the maximum number of joints.
Joining
Gutters are joined together, for example, by means of butt straps or rivets. No seal is applied at this stage.
Sealing
The gutters are sealed using a patch of membrane that is heat sealed (hot air welded) over the mechanical join area.
