ABSTRACT:
A support member for use in a support system wherein the support member is positioned under a beam of a structure is shown. The support member includes a planar base and a bottom member operatively coupled to the planar base. The bottom member has a vertically extending portion defining a thrust bearing member receiving cavity. A raised locking boss is attached to the planar base and is positioned adjacent the vertically extending portion within the thrust bearing member receiving cavity. A support member which has a planar support plate is passed through the vertically extending portion of the bottom member into mating position with the raised locking boss to lock the same in position and to prohibit rotation thereof about an axis passing perpendicular to the plane of the planar support plate. The support member includes a vertically extending support shaft which is affixed to the planar support plate and includes first coacting surface located around the periphery thereof. A thrust bearing member has a collar and outer lip having an opening extending axially therethrough with the interior thereof formed with a second coacting surface which is capable of coacting with the first coacting surface. An elongated sleeve member, which supports a top member, is in affixed to the collar. The thrust bearing member is brought into contact with the vertically extending support shaft such that said first coacting surface and the second coacting surface coact with each other and are responsive to a rotational force applied therebetween to vary the distance between the planar support plate and the thrust bearing member.
