Waterproof juncture
View Patent ↗A waterproofing flashing and resulting juncture, comprising in a first embodiment a generally horizontally positioned planar member which is positioned in sandwiched engagement between the upper peripheral edge of a shower pan or shower bench sidewall (or equivalent wallboard) and a lower peripheral edge of adjacent wallboard (or equivalent shower bench, shelf or ledge), and a vertically extending member attached to a distal edge of the horizontal member extending vertically upwardly behind the wallboard (or equivalent shower bench, shelf or ledge). An alternative form of the invention comprises a T-shaped flashing member comprised of a mid-section to which are connected first and second attachment members or wings, the wings adapted to connect the flashing to the room-facing side of the wallboard and/or shower module sections. A further version of the invention comprises a waterproof juncture comprised of a water-impermeable membrane applied over at least the upper peripheral edge of a wallboard or shower pan sidewall and a portion of an adjacent wall-forming member which is coplanar with the wall studs, which in turn will form a waterproof covering over the seam between the upper peripheral edge of the wallboard or shower pan sidewall (or equivalent shower bench, shelf or ledge) and the adjacent wall-forming member.
1. A waterproof flashing used to seal a joint between first and second wall members, the first wall member being disposed substantially vertically and ending in a first peripheral substantially horizontally oriented edge, the second wall member being disposed substantially vertically and ending in a second peripheral substantially horizontally oriented edge, the first and second peripheral edges facing each other in substantial registry and forming a space therebetween, the flashing comprising:
a Z-shaped flashing member at least partially sandwiched between the first and second peripheral edges, the flashing member comprised of a first, substantially horizontally disposed, section extending in the space between the first and second peripheral edges, the first section having a thickness;
a second, upstanding, section which is attached to the first section along a distal edge of the first section and extending substantially vertically upwardly behind at least a portion of the second wall member when installed;
a third, downwardly depending, section which is attached to the first section along a proximal edge of the first section and extending substantially downwardly in front of at least a portion of the first wall member when installed;
a row of tile applied over a projected area occupied by the space between the first and second peripheral edges and the flashing; and
the first and second peripheral edges being spaced from each other by no more than substantially the thickness of the first section of the flashing member.
2. The waterproof flashing of claim 1 , further comprising a resilient sealing agent disposed in and substantially filling the space between the first and second peripheral edges.
3. The waterproof flashing of claim 1 , further comprising one or more fasteners to mechanically connect the flashing to one or more fixed objects, wherein the fixed object(s) is a wall stud lying behind one or both of the first and second wall members.
4. A waterproof flashing used to seal a joint between a vertically oriented wallboard member, the wallboard member ending in a first substantially horizontally oriented peripheral edge, and a vertically oriented sidewall of a shower or bath tub module, the sidewall of the shower or bath tub enclosure ending in a second substantially horizontally oriented peripheral edge, the first and second peripheral edges directly opposing each other, being in substantial registry with each other, and defining a space between each other, the flashing comprising:
a z-shaped flashing member comprised of a first section extending substantially horizontally in the space between the first and second peripheral edges, the first section having a thickness;
a second, upstanding, section which is attached to the first section along a distal edge of the first section and extending substantially vertically upwardly behind at least a portion of the wallboard member;
a third, downwardly depending, section which is attached to the first section along a proximal edge of the first section and extending substantially downwardly in front of at least a portion of the sidewall member when installed;
a row of tile applied over the space between the first and second peripheral edges and the flashing; and
the first and second peripheral edges being spaced from each other by no more than substantially the thickness of the first section of the flashing member.
5. A waterproof flashing used to seal a joint between a first member, said first member consisting of one or more of a sidewall of a shower pan, a back wall of a shower bench, a shower accessory or a sidewall of a bath tub module, and a second member, said second member consisting of one or more of a legwall of a shower bench, a wallboard or a shower accessory, the first member being vertically oriented and ending in a first peripheral edge, the second member being vertically oriented and ending in a second peripheral edge, the first and second peripheral edges being substantially parallel to, directly opposing and in registry with each other, the flashing comprising:
a z-shaped flashing member comprised of a first section extending substantially horizontally in a space between the first and second peripheral edges, the first section having a thickness;
a second, upstanding, flashing member which is attached to the first flashing member along a distal edge of the first flashing member and extending substantially vertically upwardly behind at least a portion of the second member when installed;
a third, downwardly depending, section which is attached to the first section along a proximal edge of the first section and extending substantially downwardly in front of at least a portion of the first member when installed;
the first and second peripheral edges being spaced from each other by no more than substantially the thickness of the first section of the flashing member;
a row of tile applied over a projected area defined by the space when viewed in elevation.
6. The waterproof flashing of claim 5 , further comprising a row of tile applied over a projected area occupied by the space between the first and second peripheral edges and the flashing.
7. The waterproof flashing of claim 5 , further comprising one or more fasteners to mechanically connect the flashing to one or more fixed objects.
8. The waterproof flashing of claim 7 , wherein the one or more fixed objects is a wall stud disposed behind the first and second wall members.
9. The waterproof flashing of claim 5 , further comprising a resilient sealing agent disposed in and substantially filling the space between the first and second peripheral edges and at least partially encapsulating the first section.
10. The waterproof flashing of claim 9 , further comprising a row of tile applied over a projected area occupied by the space between the first and second peripheral edges and the third flashing section.
11. A waterproof flashing used to seal a joint between first and second wall members, the first wall member being substantially vertically oriented and ending in a first peripheral edge, the second wall member being substantially vertically oriented and ending in a second peripheral edge, the first and second peripheral edges facing each other in directly opposed relation and being in registry with, and defining a space between, each other, the flashing comprising:
a z-shaped flashing member comprised of a first section adapted to be placed in a space formed between the first and second peripheral edges, the first section having a thickness;
