Definitions
- This invention relates to a method of making a duct member, i.e. a length of duct of which a number can be joined end to end to form tubular ducting for, e.g., air and gas distribution systems.
- WO 2010/094385 ( PCT/EP2010/ 000433 ) published on 26 August 2010 discloses a tubular duct member comprising a plurality of sheet metal panels joined along adjacent longitudinal edges by cooperating folded sheet metal catches. The catches are pushed together such that respective detent surfaces on each catch engage behind one another to retain the edges of the sheets together.
- an insulating panel is fixed to the various panels of the duct member.
- the present invention provides a method of making a duct member comprising feeding sheet metal continuously from a roll, progressively folding the opposite edges of the sheet as it advances to form a respective folded metal catch along each edge, each catch including an upstanding wall defining with the main body of the sheet a shallow tray across the width of the sheet, dispensing a thermal
- the thermal insulator in flowable form into the shallow tray as the sheet advances so that the thermal insulator spreads out to fill substantially the full width of the tray between the upstanding walls, the liquid thereafter solidifying to form a solid thermally insulating layer, and cutting the sheet transversely into individual panels having a respective catch along each edge for in-use push fit connection to a cooperating catch along the edge of an adjacent panel.
- Figure 1 shows a duct panel produced according to an embodiment of the present invention.
- Figures 2 and 2 (a) show detailed views of assembled ducting including the duct panels of Figure 1.
- Figure 1 shows a duct panel produced according to an embodiment of the present invention.
- Figure 1(a) is an underneath plan view of a duct panel 100
- Figure 1 (b) is a cross-section on the line B-B of Figure 1 (a)
- Figure 1 (c) is an enlarged cross-section similar to Figure 1 (b) .
- the panel 100 has male and female catches respectively running along opposite parallel edges. These catches are constructed and operate generally the same as the male and female catches 14', 16' of WO 2010/094385 Figure 8 and, accordingly, the same reference numerals have been applied. The following description will concentrate on the differences from WO 2010/094385, the basic operation of the catches being assumed.
- each catch 14', 16' includes a respective upstanding wall 102, 104 formed by additional folding of the sheet metal at each edge of the panel through two 90 degree bends and one 180 degree bend, as shown in Figure 1(c) .
- the panels 100 are produced continuously from a roll of sheet metal, the edges of the sheet being progressively folded as the sheet advances from the roll to form the catches 14', 16' and the upstanding walls 102, 104, the sheet then being cut transversely into individual panels. However, after the folding of the catches and the
- liquid polyurethane (LPU)
- end flanges 118 as shown in the assembly drawing of Figure 2 and the detailed view of Figure 2 (a) , serving the same purpose as the integral flanges 18 in WO 2010/094385 Figures 1 to 4, are riveted (or alternatively spot welded) to the
- transverse cut ends of each panel for fixing each panel to an adjacent panel.
- a hard polymer lining 114 is optionally sprayed onto the exposed surface of the
- foam/insulating layer 110 Figure 1. This has two
- the hard polymer lining is a flame retardant, and provides a higher fire resistance than the underlying material.
- the hard polymer layer 114 has a thickness of about 3mm, but could range in thickness from about 0.5mm, in contrast with the layer 110 which is typically 32mm-35mm thick but could be up to around 45mm thick.
- the flame retardant polymer 114 is preferably of the type produced by BASF under the mark Elastocoat C6325/105; or by Bollom Fire Protection (UK) under the mark BroFlame.
- ducting for example as shown in Figures 2 and 2 (a) , includes an insulating layer 110 possibly coated with a polymer lining 114, a durable and relatively impervious internal lining is provided, by comparison with using for example Rockwool or equivalent as an insulator either within or around the ducting.
- This layer/lining does not accommodate rodents or harbour or promote the spread of bacteria, such as Legionella as readily as prior art systems.
- the ducting can be transported in flat packed form and when assembled can provide a relatively airtight conduit for use in many applications.
- an antimicrobial layer (not shown) can be added to the insulating layer 110.
- One suitable coating is produced by General Paints Ltd of Celbridge, Ireland under the mark Hygen
