Abstract
Abstract A connector for the interconnection in generally perpendicular array of generally C-shaped elongate structural members having a pair of flanges integrally and perpendicularly connected with the web portion thereof in which said flanges each include a flange return edge which extends inwardly of the generally C-shaped channel, which connector, upon the assembly of said interconnection, provides strengthening of the webs of each said C-shaped structural member, and a floor assembly comprising said connector and said generally C-shaped elongate structural members.

Claim 1
Independent Claim
301 words
A connector for the interconnection in a mutually perpendicular array of at least first and second elongate generally C-shaped channel elements, each of said C-shaped channel elements having a web portion and a pair of generally parallel, spaced flanges connected along longitudinal sides of said web portion each of said flanges further including a flange return edge extending perpendicularly from a free edge of said flange inwardly of the generally C-shaped channel element and generally parallel to the web portion thereof, said connector comprising: a tubular portion of generally rectangular cross-section, said tubular portion having spaced side and end walls and being dimensioned such that one of said end walls and both said side walls are received within said first C-shaped channel element between the flanges and adjacent the web of said first C-shaped channel element with said side walls of said tubular portion of said connector being perpendicular to the longitudinal length of said web and perpendicular to said flanges, said side walls of said tubular, generally rectangular portion of said connector having slots positioned to receive said return flanges of said first generally C-shaped channel element when said tubular, generally rectangular portion of said connector is received within said C-shaped channel element; and, a generally channel-shaped portion including a connector web integral with, and being an extension of one of said side walls of said tubular, generally rectangular portion of said connector, and a connector flange secured at a first end to a free end of said connector web generally perpendicular thereto, said connector flange being parallel to the web of said first C-shaped channel element, said channel-shaped portion of said connector being dimensioned to be insertable within said second C-shaped channel element between the flanges thereof and perpendicular to the longitudinal length of said second C-shaped channel element.

A web-stiffening structural joint assembly in a mutually perpendicular array including at least first and second elongate generally C-shaped elongate channel elements, each of said C-shaped channel elements having a web portion and a pair of generally parallel, spaced flanges connected along longitudinal sides of said web portion, each of said flanges further including a flange return edge extending perpendicularly from a free edge of said flange inwardly of the generally C-shaped channel element and generally parallel to the web portion thereof, and a connector interconnecting said elongate generally C-shaped channel elements at generally a right angle one to another, said connector comprising: a tubular portion of generally rectangular cross-section, said tubular portion having spaced side and end walls and being dimensioned such that one of said end walls and both said side walls are positioned within said first said C-shaped channel element between the flanges and adjacent the web of said first C-shaped channel element with said side walls of said tubular portion of said connector being perpendicular to the longitudinal length of said web and perpendicular to said flanges, said side walls of said tubular, generally rectangular portion of said connector having slots positioned receiving the return flanges of said first generally C-shaped channel element; and a generally channel-shaped portion including a connector web integral with, and being an extension of one of said side walls of said tubular, generally rectangular portion of of said connector, and a connector flange secured at a first end to a free end of said connector web generally perpendicular thereto, said connector flange being parallel to the web of the first C-shaped element, said channel-shaped portion of said connector being dimensioned to be positioned within said second C-shaped channel element between the flanges thereof and perpendicular to the longitudinal length of said second C-shaped channel element.
Claim 6
Dependent Claim
304 words
A web-stiffening structural joint assembly in a mutually perpendicular array including at least first and second elongate generally C-shaped elongate channel elements, each of said C-shaped channel elements having a web portion and a pair of generally parallel, spaced flanges connected along longitudinal sides of said web portion, each of said flanges further including a flange return edge extending perpendicularly from a free edge of said flange inwardly of the generally C-shaped channel element and generally parallel to the web portion thereof, and a connector interconnecting said elongate generally C-shaped channel elements at generally a right angle one to another, said connector comprising: a tubular portion of generally rectangular cross-section, said tubular portion having spaced side and end walls and being dimensioned such that one of said end walls and both said side walls are positioned within said first said C-shaped channel element between the flanges and adjacent the web of said first C-shaped channel element with said side walls of said tubular portion of said connector being perpendicular to the longitudinal length of said web and perpendicular to said flanges, said side walls of said tubular, generally rectangular portion of said connector having slots positioned receiving the return flanges of said first generally C-shaped channel element; and a generally channel-shaped portion including a connector web integral with, and being an extension of one of said side walls of said tubular, generally rectangular portion of of said connector, and a connector flange secured at a first end to a free end of said connector web generally perpendicular thereto, said connector flange being parallel to the web of the first C-shaped element, said channel-shaped portion of said connector being dimensioned to be positioned within said second C-shaped channel element between the flanges thereof and perpendicular to the longitudinal length of said second C-shaped channel element.
Claim 7
Dependent Claim
32 words
