Base of a steel unit

Abstract

A base for a steel unit comprises a support tube, a bottom plate, a platform and at least one girder. The bottom plate is connected to a lower end of the support tube and is installed with a plurality of retaining holes. The platform is connected to a top end of the support tube; and the platform is installed with locking holes near the four corners. Thereby, at least one girder having an end may be placed on the platform; and one end of the girder is locked to the locking holes of the platform. Therefore, a preferred shock-proof ability is achieved so that the elevated floor having a better shock tolerance and safety of the structure is improved.

What is claimed is:  
     
         1 . A base for a steel unit comprising: 
 a supporting tube;    a bottom plate connected to an lower end of said supporting tube;    a platform connected to a top end of said supporting tube; and said    platform being installed with locking holes; and    wherein the supporting, bottom plate, and platform are formed as a the support tube, bottom plate and platform are formed as an elevated device; said platform of the elevated device is installed with a main post; the adjacent edges and opposite edges of the elevated device are firmly secured with a plurality of girders; two ends of the girders are placed on the platform; two ends of the girders are locked to locking holes on the platform; a supporting post is installed at a middle portion of the girder, a structure forming by the supporting posts is used to be connected to the supporter.    
     
     
         2 . The base for a steel unit as claimed in  claim 1 , wherein a plurality of retaining holes are formed on the bottom plate for being locked to a ground by retainers.  
     
     
         3 . The base for a steel unit as claimed in  claim 1 , wherein a plurality of triangular wings are installed between the support tube and bottom plate, and connected between an outer wall of said support tube and said bottom plate.  
     
     
         4 . The base for a steel unit as claimed in  claim 1 , wherein the platform is connected to a top end of the support tube by welding.  
     
     
         5 . The base for a steel unit as claimed in  claim 1 , wherein a screw hole is formed on the platform; a top plate is installed on an upper side of said platform; the bottom of the top plate is firmly secured with a screw rod; the screw rod of said platform is screwedly connected to the screw hole of said platform so that the top plate can be screwedly connected to the upper side said platform and nut is screwedly connected to the screw rod.  
     
     
         6 . The base for a steel unit as claimed in  claim 1 , wherein the locking hole on the platform is a long slot.  
     
     
         7 . The base for a steel unit as claimed in  claim 1 , wherein a pad is installed between the platform and the girder.  
     
     
         8 . The base for a steel unit as claimed in  claim 1 , wherein the platform of the elevated device is installed with a plurality of adjustable screw holes; each screw hole is screwedly connected to an adjusting screw; the adjusting screw resists against a bottom of the girder; by the adjusting screw to rotate and push the girder to be moved longitudinally.
