A frame as claimed in claim 3, wherein each said cladding panel has its vertical side edge abutting said inside vertical surface of said flange of said Z-shaped member, a lower edge abutting a said outwardly facing end portion of a respective said flange of said lower horizontal member, and an upper edge extending above said upper horizontal member.

Claim 8

A frame as claimed in claim 3, wherein said second vertical member is fixed to said upper and lower horizontal members at positions spaced inwardly of said frame from ends of said horizontal members opposite to said first vertical member, and the side of said frame opposite said first vertical member is open.

Claim 9

A frame as claimed in claim 1, wherein the bottom of said frame opposite said upper horizontal member is open.

Claim 10

A frame as claimed in claim 1, further comprising additional horizontal and vertical members defining a subframe for a window or a door.

Claim 11

A process for manufacturing a frame having an inner face and an outer face portion of an external wall of a building, constructed by assembling and encasing a plurality of such frames, said process comprising: providing an upper horizontal C-shaped section channel member and first and second C-shaped section channel members, with each said C-shaped section channel member including a pair of spaced flanges joined by a web, with end portions of said flanges opposite said web being bent inwardly toward each other to define a mouth; rigidly assembling said C-shaped section channel members with said first vertical member extending vertically downwardly from a first end of said horizontal member and with said mouth of said first vertical member facing inwardly of said frame, with said second vertical member extending vertically downwardly from said horizontal member at a position spaced longitudinally thereof from said first vertical member and with said mouth of said second vertical member facing outwardly of said frame, and with said mouth of said horizontal member facing upwardly; vertically spacing and fixing stiffening members to said spaced flanges of said vertical members, with each said stiffener member extending between respective said spaced flanges at substantially right angles thereto; positioning cladding panels on said inner and outer faces of said frame, each said cladding panel having vertical side edges between a front side and a back side; providing a pair of Z-shaped section members, each including a web having flanges extending in opposite directions from opposite ends thereof; and fixing said pair of Z-shaped members to said horizontal member to extend vertically downwardly therefrom at a position adjacent said first vertical member and inwardly therefrom, with one of said flanges of each said Z-shaped member extending outwardly from said inner and outer faces of said frame and having opposite inside and outside vertical surfaces forming means for supporting and positioning said vertical side edges of said cladding panels to cover said inner and outer faces of said frame.

Claim 12

A process for manufacturing a frame having an inner face and an outer face portion of an external wall of a building, constructed by assembling and encasing a plurality of such frames, said process comprising: providing an upper horizontal C-shaped section channel member and first and second C-shaped section channel members, with each said C-shaped section channel member including a pair of spaced flanges joined by a web, with end portions of said flanges opposite said web being bent inwardly toward each other to define a mouth; rigidly assembling said C-shaped section channel members with said first vertical member extending vertically downwardly from a first end of said horizontal member and with said mouth of said first vertical member facing inwardly of said frame, with said second vertical member extending vertically downwardly from said horizontal member at a position spaced longitudinally thereof from said first vertical member and with said mouth of said second vertical member facing outwardly of said frame, and with said mouth of said horizontal member facing upwardly; vertically spacing and fixing stiffening members to said spaced flanges of said vertical members, with each said stiffener member extending between respective said spaced flanges at substantially right angles thereto; positioning cladding panels on said inner and outer faces of said frame, each said cladding panel having vertical side edges between a front side and a back side; providing a pair of Z-shaped section members, each including a web having flanges extending in opposite directions from opposite ends thereof; and fixing said pair of Z-shaped members to said horizontal member to extend vertically downwardly therefrom at a position adjacent said first vertical member and inwardly therefrom, with one of said flanges of each said Z-shaped member extending outwardly from said inner and outer faces of said frame and having opposite inside and outside vertical surfaces forming means for supporting and positioning said vertical side edges of said cladding panels to cover said inner and outer faces of said frame.

Claim 13

A process as claimed in claim 10, further comprising forming a plurality of spaced holes in said webs of each of said C-shaped section channel members, and thereby providing means for the supply of filling or insulating material into the interior of said frame.

Claim 14

A process as claimed in claim 10, further comprising providing a lower horizontal C-shaped section channel member including a pair of spaced flanges joined by a web, with end portions of said flanges opposite said web being bent outwardly away from each other and thereby forming means for supporting bottom edges of the cladding panels, and fixing said lower horizonal member to bottom ends of said first and second vertical members and said Z-shaped member, with said web of said lower horizontal member facing upwardly.

Claim 15

A process as claimed in claim 12, further comprising fitting a horizontal anchoring member into a cavity formed in the bottom of said lower horizontal member, with said anchoring member and said lower horizontal member having complementary surfaces substantially in planar contact.

Claim 16

A process as claimed in claim 12, further comprising forming vertical, generally rectangular holes in said upper and lower horizontal members for passage through said frame of a pillar of the building.

Claim 17

A process as claimed in claim 12, further comprising positioning said vertical side edge of each said cladding panel abutting said inside vertical surface of said flange of said Z-shaped member, with a lower edge of each said cladding panel abutting said outwardly facing end portion of said flange of said lower horizontal member, and with an upper edge of each said cladding panel extending above said upper horizontal member.

Claim 18

A process as claimed in claim 12, comprising fixing said second vertical member to said upper and lower horizontal members at positions spaced inwardly of said frame from ends of said horizontal members opposite to said first vertical member, and maintaining open the side of said frame opposite said first vertical member.

Claim 19

A process as claimed in claim 10, further comprising maintaining open the bottom of said frame opposite said upper horizontal member.

Claim 20

A process as claimed in claim 10, further comprising fixing additional horizontal and vertical members, and thereby defining a subframe for a window or a door.
