Abstract

Abstract A construction element which consists of a length of tube, rod or other rolled or extruded section which has two seatings on its periphery. The seatings are each adapted to hold at a predetermined angle to one another and a predetermined angle to the continuous length of the ends of two strips and to also hold between the strips a screwably connected wedge. The two strips are thereby firmly held into the seatings.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 139 words
A construction joint comprising: a continuous length of the tube, rod or other extruded or rolled section, having on its periphery two seatings, each of said seatings including a tongue and a pair of substantially perpendicular abutment faces adjacent said tongue; two strips, each strip having a forward edge at one end thereof, each strip including a groove; and a screwably connected wedge, said two seatings being adapted to hold said one end of each of said two strips at a pre-determined angle to the line of the continuous length and to hold said wedge between said two strips, such that the two strips are firmly held into the seatings, each of said abutment faces engaging with said forward edge corner of one of said strips each of said tongues interlocking with said groove in one of said strips.
Claim 2
Dependent Claim 139 words
A construction joint comprising: a continuous length of the tube, rod or other extruded or rolled section, having on its periphery two seatings, each of said seatings including a tongue and a pair of substantially perpendicular abutment faces adjacent said tongue; two strips, each strip having a forward edge at one end thereof, each strip including a groove; and a screwably connected wedge, said two seatings being adapted to hold said one end of each of said two strips at a pre-determined angle to the line of the continuous length and to hold said wedge between said two strips, such that the two strips are firmly held into the seatings, each of said abutment faces engaging with said forward edge corner of one of said strips each of said tongues interlocking with said groove in one of said strips.
