Abstract

A structural support column with telescopically adjustable head, includes a base, and an elongate support member extending substantially vertically from the base. The support member has a remote end opposed to the base with a cavity. A centralizing member covers the cavity at the remote end of the support member. The centralizing member has an aperture which is axially aligned with the longitudinal axis of the support member. A levelling screw is provides having a first end with a head and a second end. The second end of the levelling screw extends through the aperture in the centralizing member and is secured against removal by a levelling nut. The first end of the levelling screw is received in the rectangular cavity at the remote end of the support member. The head at the first end of the levelling screw is received in close fitting engagement in the cavity. A support bracket is positioned at the second end of the levelling screw.

Claims

1. A structural support column with telescopically adjustable head, comprising:

a base;

an elongate support member extending substantially vertically from the base and having a remote end opposed to the base with a cavity;

a centralizing member covering the cavity at the remote end of the support member, the centralizing member having an aperture which is axially aligned with a longitudinal axis of the support member;

a levelling screw having a first end with a head and a second end, the second end of the levelling screw extending through the aperture in the centralizing member and being secured against removal by a levelling nut, the first end of the levelling screw being received in the cavity at the remote end of the support member, the head at the first end of the levelling screw being in close fitting engagement in the cavity; and

a support bracket positioned at the second end of the levelling screw.

2. A structural support column with telescopically adjustable head, comprising:

a base;

an elongate support member extending substantially vertically from the base and having a remote end opposed to the base with a rectangular cavity;

a centralizing member covering the rectangular cavity at the remote end of the support member, the centralizing member having an aperture which is axially aligned with the longitudinal axis of the support member;

a levelling screw having a first end with a rectangular head and a second end, the second end of the levelling screw extending through the aperture in the centralizing member and being secured against removal by a levelling nut, the first end of the levelling screw being received in the rectangular cavity at the remote end of the support member, the rectangular head at the first end of the levelling screw being in close fitting engagement in the rectangular cavity; and

a support bracket positioned at the second end of the levelling screw.

3. The structural support column as defined in claim 2, wherein the support bracket has a depending collar with an aperture which receives the second end of the levelling screw.
