1. A support for a building structure comprising:
an elongated hollow body having first and second ends, a central axis and an interior, a first connection portion at the first end and a second connection portion at the second end;
the first connection portion comprising a first outer surface and a first inner surface and having an axial bore extending from an opening in the first outer surface having a first outer surface diameter to an opening in the first inner surface having a first inner surface diameter greater than the first outer surface diameter, the bore in the first connection portion having a first shoulder therein with a shoulder surface facing inward wherein a bolt having a head with a diameter less than the first inner surface diameter and greater than the first outer surface diameter and having a shank with a diameter less than first outer surface diameter can pass shank first through the hollow body and partially through the bore with the shank extending outward from the first connection portion;
the second connection portion comprising a second outer surface and second inner surface and having an axial hole therein extending from an opening in the second outer surface to an opening in the second inner surface and having a diameter throughout greater than the head diameter of the bolt, the axial hole having an outer shoulder therein with a shoulder surface facing inward, the axial hole configured to allow a coupler in an insertion position to be moved from outside of the body adjacent the second end through the axial hole past the outer shoulder and to permit rotation of the coupler within the axial hole from the insertion position to a captured position wherein the shoulder blocks axial motion of the coupler towards the second outer surface;
wherein when the first connection portion of a first support is adjacent and in axial alignment with the second connection portion of a second support, the first and second supports can be affixed to each other by a respective bolt having a shank passing through the axial bore in the first connection portion of the first support and engaging a threaded aperture in a coupler in the captured position within the axial hole of the second connection portion of the second support.
