Abstract
Abstract A jointing construction for laminated panels of the type having a core lamination of heat insulating material and facing sheet laminations bonded to opposed sides of the core, said joint construction comprising at least one pair of flanges each of which is defined by turning one of a pair of opposed edge portions of one facing sheet outwardly substantially perpendicular to the plane of said sheet, the jointing construction being intended to join a pair of said panels disposed in use such that one flange of one panel is adjacent one flange of the other panel, a joint cap adapted to engage said adjacent flanges, said joint cap including a bridging portion and a pair of spaced side portions each depending from said bridging portion, one side portion of the joint cap being intended to locate adjacent each flange on the side thereof adjacent the inner portion of the panel on which the respective flange is formed, each said side portion being substantially parallel to its adjacent flange, and a water seal fitted between each flange and the adjacent side portion of the joint cap.

Claim 1
Independent Claim
223 words
A jointing construction for laminated panels of the type having a core lamination of heat insulating material and facing sheet laminations bonded to opposed sides of the core, said joint construction comprising at least one pair of flanges each of which is defined by turning one of a pair of opposed edge portions of one facing sheet outwardly substantially perpendicular to the plane of said sheet, the jointing construction being intended to join a pair of said panels disposed in use such that one flange of one panel is adjacent one flange of the other panel, a joint cap engaging said adjacent flanges, said joint cap including a bridging portion extending between said flanges and a pair of spaced side portions each depending from said bridging portion, one side portion of the joint cap being disposed adjacent each flange on the side thereof opposite to the adjacent panel, each said side portion being substantially parallel to its adjacent flange, and a water seal fitted between each flange and the adjacent side portion of the joint cap, said water seal comprising membrane means extending between the adjacent surfaces of each of said flanges and the respective side portions and across the area between said flanges and sealing means providing a seal between each of said flanges and said side portions and said membrane means.

A jointing construction for laminated panels of the type having a core lamination of heat insulating material and facing sheet laminations bonded to opposed sides of the core, said joint construction comprising at least one pair of flanges each of which is defined by turning one of a pair of opposed edge portions of one facing sheet outwardly substantially perpendicular to the plane of said sheet, the jointing construction being intended to join a pair of said panels disposed in use such that one flange of one panel is adjacent one flange of the other panel, a joint cap engaging said adjacent flanges, said joint cap including a bridging portion extending between said flanges and a pair of spaced side portions each depending from said bridging portion, one side portion of the joint cap being disposed adjacent each flange on the side thereof opposite to the adjacent panel, each said side portion being substantially parallel to its adjacent flange, and a water seal fitted between each flange and the adjacent side portion of the joint cap, said water seal comprising membrane means extending between the adjacent surfaces of each of said flanges and the respective side portions and across the area between said flanges and sealing means providing a seal between each of said flanges and said side portions and said membrane means.
Claim 3
Dependent Claim
39 words
A jointing construction as claimed in claim 1 wherein a rabbeted edge is formed in the core lamination adjacent each flange, the aligned rabbeted edges of said pair of panels in combination with said adjacent flanges forming a channel.
Claim 4
Dependent Claim
21 words
A jointing construction as claimed in claim 2 wherein a plug formed of heat insulating material is located in said channel.
Claim 5
Dependent Claim
25 words
A jointing construction as claimed in claim 3 wherein the plug is dimensioned so as to protrude beyond the outer ends of the adjacent flanges.
Claim 6
Dependent Claim
198 words
A jointing construction as claimed in claim 4 wherein said membrane means includes a first membrane extending along the length of the joint, said first membrane in addition extending across said joint from adjacent the base of each flange on the side thereof remote from said channel, the inner portion of said first membrane being disposed between the channel and the plug and each longitudinal side portion of the membrane being disposed adjacent one of said flanges, a second membrane extending along the length of said joint, said second membrane in addition extending across the joint from adjacent the base of each flange on the side of said first membrane remote from the flange, said second membrane passing across said protruding end of of the plug, the sealing means comprising a layer of non-drying sealant providing a seal between each longitudinal side portion of the first membrane and the adjacent flange, a layer of non-drying sealant providing a seal between each longitudinal side portion of said first membrane and an adjacent portion of said second membrane, and a further layer of non-drying sealant providing a seal between said second membrane and each side portion of the joint cap.
Claim 7
Dependent Claim
192 words
A joint construction as claimed in claim 2 wherein said membrane includes a first membrane extending along the length of the joint, said first membrane in addition extending across the joint from adjacent the base of each flange on the side thereof remote from said channel, the inner portion of said first membrane being disposed within said channel and each longitudinal side portion of the membrane being disposed adjacent one of said flanges, a second membrane extending along the length of said joint, said second membrane in addition extending across the joint from adjacent the base of each flange on the side of said first membrane remote from the flange, said second membrane traversing the outer end of said channel, the sealing means comprising a layer of non-drying sealant providing a seal between each longitudinal side portion of the first membrane and the adjacent flange, a layer of non-drying sealant providing a seal between each longitudinal side portion of said first membrane and an adjacent portion of said second membrane, and a further layer of non-drying sealant providing a seal between said second membrane and each side portion of the joint cap.
Claim 8
Dependent Claim
41 words
A jointing construction as claimed in claim 5 wherein each side portion of the joint cap is secured to its respective flange by connecting means, said connecting means passing through said first membrane, said second membrane and said layers of sealant.
Claim 9
Dependent Claim
41 words
A jointing construction as claimed in claim 6 wherein each side portion of the joint cap is secured to its respective flange by connecting means, said connecting means passing through said first membrane, said second membrane and said layers of sealant.
Claim 10
Dependent Claim
49 words
A jointing construction as claimed in claim 1 wherein the free end of each side portion of the joint cap is adapted to engage on the particular facing sheet of the panel from which its associated flange is formed, each said free end being provided with a safety edge.
