Adjustable metal framing system and connecton

A connection comprising an outer support member and an inner support member with apertures secured by a connection member:

• said outer support member having a C-shape configuration with a web attached to a first flange with a lip and a second flange with a lip opposite said first flange with said lip, said outer support member encompasses an (OD) outside planar surface and an (ID) inside planar surface and a top end and a bottom end, said inner support member encompasses an (OD) outside planar surface and an (ID) inside planar surface and a top end and a bottom end comparably similar to said outer support member with a smaller profile able to form a concentric C-shape configuration or a U-shape configuration, with said first flange and second flange having a continuous indentation leaving the corners at said web and said lip to abut said inside planar surface of said outer support member;
• said outer support member with a first aperture spaced along the centerline of said web setback from the top end and a second aperture aligned and setback from said bottom end, said first aperture and said second aperture having said outer planar surface cut through to said inner planar surface with said first aperture and said second aperture each having a first perimeter edge and a second perimeter edge opposite said first perimeter edge with a third perimeter edge opposite said fourth perimeter edge between said first perimeter edge and said second perimeter edge, said first perimeter edge and said second perimeter edge form a pair of first perimeter notches with an opening cut into said first perimeter edge and another opening cut into said second perimeter edge forming a pair of said first perimeter notches with at least a second pair of perimeter notches cut into said first and said second perimeter edge of said first aperture and said second aperture, said perimeter notch has a first notch edge, a second notch edge and a back notch edge;
• said inner support member with a third aperture setback from the top end and a fourth aperture setback from the bottom end, said third and said fourth aperture have a pair of said first and said second perimeter notches comparably similar to said outer support member, said inner support member having an outer planar surface able to slide within the said inside planar surface of said outer support member to align a pair of said perimeter notches at said first aperture or said second aperture of said outer support member to align with a pair of said perimeter notches at said third aperture or said fourth aperture;
• said first connector member has a first connector notch and a second connector notch opposite said first connector notch to engage said first aperture, or engage said second aperture, or engage a combination of two adjacent said apertures and when aligned form said first-second aperture between said outer support member and said inner support member, said first and second connector notch has an indentation cut into the same or a different element to engage said first perimeter side end and said second perimeter side edge of said first and said second perimeter notch, setback from a front end and a back end of said connector member, and fits tight into the narrow width opening between said first perimeter edge and said second perimeter edge at said apertures of said outer and said inner support members, said first and second perimeter notches have sloped notch side edges for easy access to said first and said second connector notch;

A method of erecting an expandable wall structure, of the method comprising:

• attaching a fixed top track to a ceiling or a sliding top track to a ceiling;
• attaching a bottom track to a floor, said bottom track located directly below said top track;
• inserting an inner support member into a outer support member, each said support member having an aperture at a top end and a bottom end, said outer support member having said aperture with L-shaped perimeter notches at the upper and lower aperture at said first and said second end, said inner support member having an aperture at a top end and a bottom end with said top end having said aperture with L-shape perimeter notches and said second end having said sliding top track with a recessed gap with deep straight gaps on both sides of said recessed gap, each said outer and said inner support member has a connection aperture above said first and said second aperture at each end with each connection aperture having perimeter notches;
• insert said inner support track into said outer support track, set an inner web against an outer web or reverse said inner support member against the lip of said outer support member;
• align said connection apertures in said outer and said inner support members to form a continuous inner-outer aperture;
• extending the inner support member with said L-shape perimeter notches to said fixed top track, or extend the opposite end of said inner support member with said recessed gap and said straight gaps into said sliding top track, leaving said inner support member overlapping said outer support member;
• insert a connection clip or a connection member through the connection apertures by pressuring said clip or connection member into the perimeter notches and, or the connection member with the lip notches;
• install mineral wool to framing members as required by building codes;
• abut and connect drywall with fasteners against said inner and said outer support members as required by building codes;
• install fire caulking as required by building codes.
