The panel 1 comprises a steel skin or backing tray (2) and an external steel skin (3) with a layer of foam insulation material (4) such as a phenolic or polyurethane based foam material therebetween. One of the skins, in this case the external skin 3 has a plurality of mountings for fixing cladding elements such as tiles (5) to the panel to form a cladding. The mountings comprise rails (10) and fasteners (12) for fastening the rails (10) to the external skin (3). Each fastener (12) comprises an internal clamping sleeve (15) and a bolt (16). A hole is first drilled through the skin (3) and the sleeve (15) is inserted. On tightening of the bolt (16), the sleeve (15) splays and is clamped against the inside surface of the external skin (3), and the rails (10) are fixed to the panels. To enhance the peel strength of the composite panel a layer (30) of an adhesive is applied to the internal face of the external skin (3). The adhesive layer (30) is a pre-lay-down adhesive which is compatible with the material of the insulting core (4). The use of such an adhesive greatly enhances the peel strength of the panel and enables the panel to carry the additional load of the cladding tiles.

A rigid polymeric insulating foam board comprises an upper facing 2, a lower facing 1 and a foam layer 3 between the facings 1, 2. The foam sandwich is delivered into an oven 10 and the continuous length of foam board exiting the oven is delivered through a curing station A. The foam board is cut to length B, trimmed C, optimally re-bated D, the cut board lengths are stacked E and wrapped F. A cooling station 50 for the wrapped stacks 55 comprises upper and lower stack conveyors 51, 52. Scissors-type lifters 56, 57 are provided at the infeed and outfeed end to divert a stack 55 to or from a cooling conveyor 51, 52.
摘要:
A high pressure phenolic resin is impingement mixed with a low pressure acid stream in a mixing head (1) to form a phenolic insulating foam reactant mixture. The mixing head has two oppositely directed high pressure inlet ports (2, 3) each connected to a phenolic resin stream at a pressure of at least 140 bar. Acid at a pressure of about 3 bar is drawn into the mixing head (1) through an inlet port (6). The mixing head (1) may be mounted on a lay-down traversing poker (10) to form a phenolic insulating body such as a composite panel.

A composite roof panel for flat or low pitch roofs comprises a generally flat external sheet (2), a profiled internal decking sheet (3), and an insulating core (4) between the external sheet (2) and internal sheet (3). The external sheet (2) has an external male projecting part (10) and an internal recess part (11) on one side for engagement, on assembly, with a corresponding external recess part (12) and projecting inner male part (13) respectively on the opposite side of the panel. At least a portion of the side edges (21, 22) of the insulating core (4) between the joint forming portions of the external sheet and internal lining sheet has an inclined wedge profile. The inclined wedge profiles of the side edges (21, 22) of the insulating core (4) form oppositely directed wedge faces. A side edge (22) of the insulating core (4) of one panel (20A) is matched with the opposite side edge (21) of an adjacent panel (20B). On assembly, a first overlap portion (30) of the panel receives a second overlap portion (31) of the adjacent panel. A joint reinforcing plate (40) has a downwardly extending locator defined by a projection (41) which is located in a gap (35) at the joint to ensure that the reinforcing plate (40) is accurately positioned relative to the joint. The plate (40) has holes (42, 43) to receive joint fasteners (44, 45).

A fire resistant edge seal 100 for sealing a joint between adjacent panels 101, 102 is in the form of a sheet or tape and comprises a resin fabric prepreg backing layer 105 pre-bonded to a layer 106 of intumescent material. In a fire, phenolic resin in the prepreg bonds on to the foam on the foam surface at the panel edge. The prepreg cures to provide a thermal shield to the foam surface that it covers. The combination of a phenolic glass prepreg and an intumescent material provides substantially improved fire protection to the joints between adjacent panels.

A cleaning carriage 50 is mounted for vertical movement and is also movable transversely of separated panels 10, 12 along tracks 51 for movement of the carriage 50 across the gap between the separated panels 10, 12. The carriage 50 is moved from a raised inactive position to an extended or lowered active position and is then driven across the gap created between the panels 10, 12 to clean and de-burr the end faces 11, 13. Material removed on cleaning is collected in hoppers 52 to prevent contamination in the region of the panels. To clean the upper and lower faces 70, 71 of a panel 10, the panel is led over a lower face cleaning brush 80 and under an upper face cleaning brush 81 at a panel face cleaning station 85. The brushes 80, 81 are provided in the form of belts that brush across the faces 70, 71 of the panel 10 as the panel travels along a conveyer 86. Debris is brushed into inlets 87 of a vacuum removal system 88.
摘要:
An insulated wall panel comprises a profiled external sheet (2), an internal lower sheet (3), and an insulating core between the sheets (2, 3). The external sheet (2) has an external male projecting part (10) and an internal recess part (11) on one side for engagement, on assembly, with a corresponding external recess part (12) and projecting male inner part (13) on the opposite side of a panel. A seal (20) is interposed between a flattened nose portion (13a) and a flat wall (11a) for effective sealing engagement. The outer gap (g) between adjacent sheets (2) is substantially uniform and set by engaging the external male part (10) against an inclined wall (25) of the adjacent external skin (2). The internal lining sheet (3) has an inner recess part (30) and an outer male projecting part (31) on one side and a corresponding inner projecting male part (32) and outer recess (33) on the opposite sides. The internal joint between adjacent internal sheets is sealed by a seal (35). A fixing pin (40) may be extended through the overlapping internal sheets (3).
摘要:
An insulated foam board is manufactured by leading a first facing (1) from a reel and laying down liquid foam reactants. A second facing (2) from a supply reel is laid over the reactants forming a sandwich. The foam is expanded in an oven (12) and the board is cut to a desired length. One or both facings (21, 22) are removed and re-wound onto a reel (24, 25) for re-use. A coating in the form of a metallised paint is applied (30, 35) in-line to one or both faces of the foam core (23), after removal of the facings (21, 22). The painted boards have enhanced heat insulation properties.
