Abstract
A method of sealing the space between adjoining lengths of guttering, comprises the steps of bonding a sheet of flexible liquid impermeable material (6) to a strip (4) of such material secured or adhered to the adjoining end region of one of each length of guttering (1, 2). Bonding may be achieved by hot air or hot plate welding or by solvent welding. <IMAGE>
Description
Improvements in and Relating to
Jointing Systems for Water Ways
This invention relates to jointing systems for water ways. More especially, but not exclusively, the invention relates to apparatus for and methods of making sealed joints between adjoining lengths of guttering, such as roof eave gutters, and parapet and valiey gutters of buildings.
It is to be understood that the term "water way" is to be taken to include such items as gutters, gulleys, pipes and other similar items for conveying liquid from one location to another.
Jointing methods currently employed for joining together lengths of gutter generally comprise the step of compressing a waterproof sealing product between two gutter surfaces and then securing these surfaces tightly together.
Various waterproof sealing products are used, these ranging from mastics and silicone sealants to compressible materials which may be self adhesive on one or both sides.
Conventional methods of securing the overlapping gutter surfaces include the use of bolts, nuts and washers, or rivets, or may be achieved by forced interlocking or snapping together of overlapping surfaces using special tools.
With all jointing methods, an allowance for thermal movement should be made.
Limitations of performance and effective life of joints made by said methods vary considerably and in the case of some methods without any controllable consistency.
With the use of mastics, silicone sealants and stuck or self adhesive compressible materials, dry surfaces are usually essential to ensure satisfactory adhesion. Also, especially with mastics and silicone sealants, the effectiveness of the joints made depends almost entirely on the complete joint being formed on site.
Interlocking or snapping techniques are likely to restrict not only the method of producing the gutter but also the shapes and sizes that can be achieved, and it is unlikely that such methods could be applied to all types of gutter required.
This invention sets out in one aspect to provide a jointing system for guttering and the like which provides a relatively secure sealed joint between adjoining gutter lengths.
According to the present invention in one aspect, there is provided a jointing system for sealing the space between adjoining lengths of guttering, the joint comprising a sheet of flexible liquid impermeable material capable of being bonded to a strip of such material secured or adhered to the adjoining end region of one or each length of guttering.
According to the present invention in another aspect, there is provided a method of sealing the space between adjoining lengths of guttering, the method comprising the steps of bonding a sheet of flexible liquid impermeable material to a strip of such material secured or adhered to the adjoining end region of one of each length of guttering.
Bonding may be achieved by hot air or hot plate welding or by solvent welding.
A strip of the liquid impermeable material may be adhered to the end regions of each gutter length, the sheet of liquid impermeable material (which may be the same material as that used for the strips) being bonded, e.g. by hot air welding, hot plate welding or solvent welding to the exposed faces of the strips on site.
Alternatively, a strip of liquid impermeable material may be adhered to one end region of one gutter length, with the sheet of liquid impermeable material being adhered to the end region of the other gutter length and being bonded on site, e.g. by hot air welding to the exposed face of the strip by being overlaid onto that strip and hot air welded thereto.
Suitable sheet materials include PVC (polyvinyl chloride, CPE (chlorinated polyethylene), CSM (chlorosulphanated polyethylene), VET (vinyl ethylene terpolymer), PIB (polyisobutylene) IIR (butyl rubber),
EPDM (ethylene propylene diene monomer), ECB (ethylenecopolymer plus bitumen), butyl, (LDPE) low density polyethylene, and ultra linear low density polyethylene (ULLDE). The sheet thickness is typically from 0.5 mm to 2.0 mm.
The invention will now be described by way of example only with reference to the accompanying diagrammatic drawings in which:
Figures 1, 2 and 3 are perspective views of apparatus in accordance with the invention during the stages of a joint being made between adjoining lengths of guttering.
Figures 1 to 3 of the drawings illustrate the way in which joints in new guttering can be made. Two adjoining gutters 1,2 are shown in Figure 1, the space to be sealed being shown at 3. Strips 4 of flexible liquid (e.g.
water) impermeable material are adhered to the gutters 1, 2 and a metal strip 5 is welded, bolted or otherwise secured across the space 3 as shown in Figure 2. Finally, a sheet 6 of flexible impermeable material is hot air or hot/plate welded or solvent welded to the strips 4 to complete the seal as shown in Figure 3. The metal strip 5 is optional.
Where downpipe openings are present in a gutter length, suitably shaped outlet pieces may be provided.
Suitable sheet materials include PVC (polyvinyl chloride, CPE (chlorinated polyethylene), CSM (chlorosulphanated polyethylene), VET (vinyl ethylene terpolymer), PIB (polyisobutylene) IIR (butyl rubber),
EPDM (ethylene propylene diene monomer), ECB (ethylenecopolymer plus bitumen), butyl, (LDPE) low density polyethylene, and ultra linear low density polyethylene (ULLDE). The sheet thickness is typically from 0.5 mm to 2.0 mm.
The invention has particular application for use with single skin metal guttering produced by any suitable process such as bending of folding of sheet metal, or extruding and casting of molten/liquid metal to achieve any suitable shape such as half round, ogee and box profile, of any suitable size, for use in any suitable location such as roof eaves, valley or parapet situations.
The strips are preferably of a width not less than 50mm and not more than 100mm.
Each gutter piece may be of any length; typically, said gutter lengths will be not less than lm and not more than 3m.
The strips of flexible fluid-impermeable material are located normally at or towards each end of the respective length of gutter. Their exact position is, however, variable depending on the exact design and/or style of gutter to be joined.
If the gutter has external collars then the strips may be fitted precisely at the end of the gutter. If the gutter is plain ended without collars, however, then the strip need not be positioned at the end of the respective gutter lengths but set back a sufficient distance to allow for the use of an internal closure piece. Such a closure piece may be necessary because of thermal movement and where an external appearance of continuous gutter line and, possibly, colour are required.
After the process of adhering the strips of fluidimpermeable material to the gutter has been completed, a layer of liquid PVC or fluid-impermeable material may be applied to the leading edge of the strip for increased protection.
Each length of gutter may be supplied with a separate sheep of fluid-impermeable material, for use as an internal union sealing strip, either bonded/adhered to the fluid-impermeable material already fitted to one end region of the gutter, or loose, for final bonding/adhering on site during installation.
With either situation the final fitting and sealing of the fluid-impermeable sealing strip to one or each end of the adjoining gutter is achieved by hot air or hot plate welding or a solvent welding technique or an appropriate bonding/adhering agent.
In all situations either at works or on site, the bonding/adhering process of a fluid-impermeable material to itself is completed by the application of a bead of liquid PVC of fluid-impermeable material to all leading edges.
It will be appreciated that the foregoing is merely exemplary of gutter jointing systems in accordance with the invention and that modifications can readily be made thereto without departing from the true scope of the invention.
