Adjustable beam support

Abstract

A support apparatus provides a vertical strut having a threaded portion at a lower end and a strut cap positioned on an upper end. A beam support yolk engages a structural beam and the support yolk rotationally engages the strut cap. A strut base provides a threaded receiver and a cavity, the cavity positioned below the threaded receiver. The threaded portion of the strut engages the threaded receiver. The strut further provides a device for rotational advantage for rotating the strut and the strut cap for adjustment in vertical position of the support yolk relative to a support surface under the strut base.

What is claimed is:  
     
         1 . A support apparatus comprising: a vertical strut providing at a lower end, a threaded portion; a strut cap positioned on an upper end of the strut and integrally joined with the strut cap is a beam support yolk extending upwardly, the support yolk rotationally engaged with the strut cap; a strut base providing a threaded receiver and a cavity, the cavity positioned below the threaded receiver; the threaded portion of the strut engaged with the threaded receiver; the strut further providing a means for rotational advantage for rotating the strut within the threaded receiver for vertical adjustment of the support yolk relative to a support surface under the strut base.  
     
     
         2 . The apparatus of  claim 1  wherein the rotational advantage means is a pair of opposing flat surfaces on the strut.  
     
     
         3 . The apparatus of  claim 1  wherein the rotational advantage means is a rod engaged within a transverse clearance hold in the strut, the rod extending laterally from the strut.  
     
     
         4 . A support apparatus comprising in combination: a structural beam; and a vertical strut providing at a lower end, a threaded portion; a strut cap positioned on an upper end of the strut and integrally joined with the strut; a beam support yolk engaging the structural beam, the support yolk rotationally engaged with the strut cap; a strut base providing a threaded receiver and a cavity, the cavity positioned below the threaded receiver; the threaded portion of the strut engaged with the threaded receiver; the strut further providing a means for rotational advantage for rotating the strut, strut cap and support yolk for adjustment in vertical positioning of the support yolk relative to a support surface under the strut base.  
     
     
         5 . The apparatus of  claim 4  wherein the rotational advantage means is a pair of opposing flat surfaces on the strut.  
     
     
         6 . The apparatus of  claim 4  wherein the rotational advantage means is a rod engaged within a transverse clearance hole in the strut, the rod extending laterally from the strut.  
     
     
         7 . A support apparatus comprising in combination: a structural beam; and a vertical post providing at an upper end thereof, a hollow portion; a metal plate positioned over the top end of the post and providing a threaded center hole; a threaded rod engaged with the center hole and thereby able to rotate for vertical advancement in the hole; the rod engaged with a beam support yolk engaging the structural beam.
