Abstract
The invention relates to a cavity tray for use in a cavity wall, comprising two spaced apart flanges each adapted in use to lie in or adjacent a respective skin of the wall, a connector connecting the two spaced apart flanges, and an arcuate transitional part leading to at least one flange whereby a super- or sub-posed damp-proof men, her may be adhered thereto with substantially no discontinuity.
Claims12
A cavity tray disposed in a gap between and engaged with inner and outer skins of a building wall, the cavity tray comprising:
- a continuous one-piece flexible body constructed of thin sheet-like non-metallic material;
- said body having sheet-like and substantially planar upper and lower flange parts disposed at opposite extremities of the body and disposed in their entireties in vertically and laterally spaced relation and engaged with the respective inner and outer skins of the building wall, said lower flange part extending generally horizontally and fixedly disposed within the outer skin of the wall;
- said body including an inclined flat and elongated sheet-like intermediate part extending vertically and laterally between and interconnected to said upper and lower flange parts, said intermediate part extending in angled relation relative to both of said upper and lower flange parts;
- said body further including a lower arcuately elongate sheet-like transitional part integrally and directly located between said intermediate part and said lower flange part, said lower transitional part having a vertically rounded and arcuately elongate profile as it extends between said lower flange part and said intermediate part, said lower transitional part having horizontal and vertical flexibility to allow the upper flange part to be positionally movably adjusted horizontally and vertically relative to the lower flange part to accommodate variations between the inner and outer skins, and said arcuately elongate profile being free of fold lines and abrupt directional discontinuities for permitting a damp-proof member adhesively bonded thereto so that there is substantially no discontinuity between the lower transitional part and the damp-proof member to prevent the development of a leakage path therebetween;
- and
- said body also including a flat sheet-like end wall part integrally secured to and projecting substantially vertically upwardly from concurrent side edges of said lower flange part, said lower transitional part and at least a portion of said intermediate part.

A cavity tray disposed in a gap between and engaged with inner and outer skins of a building wall, the cavity tray comprising:
- a continuous one-piece flexible body constructed of a thin sheet-like non-metallic material which is deformed both vertically and horizontally to terminate in generally horizontally extending upper and lower free edges which are both vertically and laterally spaced apart;
- said body having flat and substantially planar sheet-like upper and lower flange parts disposed in their entireties in vertically and laterally spaced relationship and secured to the respective inner and outer skins of the building wall, the lower flange part extending generally horizontally and being fixedly secured within the outer skin;
- said body including an inclined flat and elongate sheet-like intermediate part extending vertically and laterally between and interconnecting said upper and lower flange parts, said intermediate part being disposed in angled relationship relative to both of said upper and lower flange parts and being positioned in the gap between the inner and outer skins;
- said body also including an upper vertically arcuately elongate sheet-like transitional part integrally and directly joining said intermediate part and said upper flange part;
- said body further including a lower vertically arcuately elongate sheet-like transitional part integrally and directly joining said intermediate part to said lower flange;
- each of said upper and lower transitional parts having both horizontal and vertical flexibility to permit relative positional movement between said upper and lower flange parts to accommodate for positional variations between said inner and outer skins;
- said lower transitional part having a smooth vertically rounded profile in the elongated direction from said lower flange part to said intermediate part so as to be free of fold lines and abrupt directional discontinuities so as to have smooth exterior surfaces for adhesive securement to a damp-proof course;
- and
- said body still further including a generally flat sheet-like end wall part integrally secured to and projecting substantially vertically upwardly from concurrent side edges of said lower flange part, said lower transitional part and at least a portion of said intermediate part.
