Removable safety stanchion post arrangement

Abstract

A floor perimeter safety rail arrangement for the protection of workers on a cement floor. The cement floor has an upper surface thereon upon which they are working. The rail arrangement comprises a cement encasable hollow receiving base having a lower end for welded attachment to an “I” beam support surface and a “floor-even” upper end arranged to be even with the upper surface of the cement floor; a stanchion post removably securable onto the receiving base; and a locking arrangement for temporarily securing and unlocking the stanchion post with respect to the receiving base; wherein the base comprises a means for temporarily securing the stanchion to the upper surface of the floor, wherein the “floor-even” upper end of the base also comprises a means for leaving a flat planar floor where nothing extends beyond the upper surface of the floor upon removal of the stanchion from the base encased within the cement floor.

1 . A floor perimeter safety rail arrangement for the protection of workers on a cement floor, said cement floor having an upper surface thereon upon which they are working, comprising: 
 a cement encasable hollow receiving base having a lower end for welded attachment to an “I” beam support surface and a “floor-even” upper end arranged to be even with said upper surface of said cement floor;    a stanchion post removably securable onto said receiving base; and    a locking arrangement for temporarily securing and unlocking said stanchion post with respect to said receiving base; wherein said base comprises a means for temporarily securing said stanchion to said upper surface of said floor, wherein said “floor-even” upper end of said base also comprises a means for leaving a flat planar floor where nothing extends beyond said upper surface of said floor upon removal of said stanchion from said base encased within said cement floor.    
   
   
       2 . The safety rail arrangement as recited in  claim 1 , wherein said stanchion is “L” shaped in cross-section to permit ease of access to said locking arrangement.  
   
   
       3 . The safety rail arrangement as recited in  claim 1 , wherein said stanchion has a plate across a lower end thereof.  
   
   
       4 . The safety rail arrangement as recited in  claim 3 , wherein said receiving base has a plate arranged across an upper end thereof.  
   
   
       5 . The safety rail arrangement as recited in  claim 4 , wherein said locking arrangement comprises a vertically displaceable bolt arranged through said plate on said upper end of said receiving base.  
   
   
       6 . The safety rail arrangement as recited in  claim 5 , wherein said bolt extends through said plate arranged at said lower end of said stanchion.  
   
   
       7 . The safety rail arrangement as recited in  claim 6 , wherein a removable nut is arranged on an upper end of said bolt.  
   
   
       8 . The safety rail arrangement as recited in  claim 1 , wherein said locking arrangement comprises a diagonally arranged bolt extending through a lower portion of said stanchion and into a threaded receiving member angularly disposed in said receiving base.  
   
   
       9 . The safety rail arrangement as recited in  claim 1 , wherein said locking arrangement comprises a threaded opening on an upper surface of said receiving base, and said stanchion has a threaded annular surface on a lower end thereof, to threadably engage and disengage of one another, for simple respective twisting securement and separation of said stanchion with respect to said receiving base.  
   
   
       10 . A method of providing a temporary safety rail arrangement to a periphery of a floor of a building comprising: 
 welding a lower end of a receiving base to an upper surface of an I beam defining a periphery said floor of said building;    securing a removable stanchion to said receiving base by a locking arrangement disposed therewith to provide a temporary safety rail;    pouring concrete onto said floor of said building to a level even with an upper end of said receiving base to define a cement floor; and    permanently encasing said receiving base in concrete on said I beam, up to said upper end of said base so that nothing extends above said concrete on said floor at said receiving base when said removable stanchion is removed therefrom.    
   
   
       11 . The method as recited in  claim 10 , including: 
 securing a safety line to said stanchion.    
   
   
       12 . The method as recited in  claim 11 , including: 
 unsecuring said stanchion on said base;    removing said unsecured stanchion from said base; and    providing an unemcumbered flat cement floor with nothing extending above the surface of said floor upon removal of said stanchion from said base in said cement floor.    
   
   
       13 . The method as recited in  claim 12 , including: 
 re-using said removed stanchion as part of another safety rail arrangement in a further receiving base.    
   
   
       14 . The method as recited in  claim 10 , wherein said locking arrangement comprises an elongated bolt disposed between said stanchion and said base with a nut threaded onto an upper end of said bolt.  
   
   
       15 . The method as recited in  claim 10 , wherein said locking arrangement comprises a displaceable bolt engaged between said stanchion and said receiving base.  
   
   
       16 . The method as recited in  claim 13 , including: 
 unthreading said nut from said bolt; and    dropping said bolt into said base from its stanchion securement position.    
   
   
       17 . The method as recited in  claim 15 , wherein said upper end of said bolt when said nut is unthreaded therefrom is even with said upper end of said base.
