Abstract
Abstract Two elongated metallic profiles each formed with two pairs of flanges each of which forms a longitudinally extending groove are positioned with the two grooves of each profile parallel and opening toward the two grooves of another such profile. An elongated bar of insulating material having a pair of longitudinally extending sides is fitted between each groove of each profile and the corresponding groove of the other profile. This forms a longitudinally extending passage defined on two opposite sides by the two insulating bars and on the other two sides by the two profiles. A tool is disposed through this passage so as plastically and permanently to deform the inner flanges outwardly and into intimate tight contact with the bars.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
120 words
A construction element comprising: an elongated bar having a pair of longitudinally extending sides and formed along each of said sides with a longitudinally extending recess having a laterally directed face; a pair of elongated metallic profiles each formed with a pair of flanges forming a respective groove receiving a respective side of said bar, at least one of said flanges of each of said pairs being plastically deformed into the respective recess and having a face bearing on the face of the respective recess; a coating on at least one of said faces; and particles imbedded in and projecting from said coating, whereby the coefficient of friction between said bar and said profiles is greatly increased at said recesses.
Claim 2
Dependent Claim
120 words
A construction element comprising: an elongated bar having a pair of longitudinally extending sides and formed along each of said sides with a longitudinally extending recess having a laterally directed face; a pair of elongated metallic profiles each formed with a pair of flanges forming a respective groove receiving a respective side of said bar, at least one of said flanges of each of said pairs being plastically deformed into the respective recess and having a face bearing on the face of the respective recess; a coating on at least one of said faces; and particles imbedded in and projecting from said coating, whereby the coefficient of friction between said bar and said profiles is greatly increased at said recesses.
Claim 3
Dependent Claim
39 words
The construction element defined in claim 1, wherein said recesses each extend longitudinally the full length of said bar along the respective side and are shaped so that said bar is thicker outside said recesses than at said recesses.
Claim 4
Dependent Claim
19 words
The construction element defined in claim 2, wherein said one flanges are formed with a region of reduced thickness.
Claim 5
Dependent Claim
19 words
The construction element defined in claim 3, wherein each of said regions is formed with a longitudinally extending groove.
Claim 6
Dependent Claim
18 words
The construction element defined in claim 2, wherein each of said one flanges is generally rectangular in section.
Claim 7
Dependent Claim
22 words
The construction element defined in claim 2, wherein each of said one flanges tapers transversely of the elongation of the respective profile.
Claim 8
Dependent Claim
16 words
The construction element defined in claim 2, wherein each of said one flanges is of L-section.
Claim 9
Dependent Claim
45 words
The construction element defined in claim 2, wherein each of said one flanges has a face turned toward the other flange of the respective pair and formed with a lip extending toward the respective other flange and imbedded in the respective side of said bar.
Claim 10
Dependent Claim
19 words
The construction element defined in claim 2, wherein each of said one flanges is formed with a plastified welt.
Claim 11
Dependent Claim
24 words
The construction element defined in claim 2, wherein the other flange of each of said pairs is substantially stronger than the respective one flange.
Claim 12
Dependent Claim
71 words
The construction element defined in claim 2; further comprising a second such bar spaced from and parallel to the first-mentioned bar, each of said profiles being provided adjacent the first-mentioned pair of flanges with a second pair of flanges forming a second groove parallel to the first-mentioned groove and receiving the sides of the second bar in the same manner as the first flanges receive the sides of the first bar.
Claim 13
Dependent Claim
47 words
The construction element defined in claim 11, wherein said one flange of each of said pairs is that flange closer to the other pair of flanges of the respective profile, said one flanges being deflected outwardly away from each other and being received in the respective recesses.
Claim 14
Dependent Claim
26 words
The construction element defined in claim 12, wherein the other flanges of said pairs are substantially greater in cross-sectional size and stronger than said one flanges.
