Screed device and system

Abstract

A screed grading device is provided that simplifies the process of grading a floor when screeding. The screed grading device comprises: a base, for being positioned on a substrate; and a platform, coupled to the base by one or more spacing members, the platform configured to provide a reference surface when screeding on the substrate. A height of the platform relative to the base is adjustable.

1 . A screed grading device comprising:
 a base, for being positioned on a substrate; and   a platform, coupled to the base by one or more spacing members, the platform configured to provide a reference surface when screeding on the substrate;   
       wherein a height of the platform relative to the base is adjustable. 
     
     
         2 . The screed grading device of  claim 1 , wherein the base and platform are coupled by a threaded spacing mechanism, wherein the height of the platform is adjustable relative to the base by rotation of the platform relative to the base 
     
     
         3 . The screed grading device of  claim 1 , wherein a first threaded member extends upwardly from base, and a second threaded member extends downwardly from platform. 
     
     
         4 . The screed grading device of  claim 3 , wherein the first and second threaded members include inwardly and outwardly threaded spacing members, wherein the outwardly threaded spacing member is configured to be received in, and engage with, the inwardly threaded spacing member. 
     
     
         5 . The screed grading device of  claim 1 , wherein the platform includes a screw drive, enabling the platform to be rotated by a tool. 
     
     
         6 . The screed grading device of  claim 1 , wherein the platform comprises a substantially planar upper surface. 
     
     
         7 . The screed grading device of  claim 6 , wherein the platform is substantially planar. 
     
     
         8 . The screed grading device of  claim 1 , wherein the platform is substantially circular in shape. 
     
     
         9 . The screed grading device of  claim 1 , wherein the platform includes one or more notches for supporting string. 
     
     
         10 . The screed grading device of  claim 9 , wherein the platform includes a plurality of notches around a periphery of the platform. 
     
     
         11 . The screed grading device of  claim 1 , comprising an upper member, unitarily formed of plastic, and lower member, unitarily formed of plastic. 
     
     
         12 . The screed grading device of  claim 1 , wherein the base includes a substantially planar lower surface. 
     
     
         13 . The screed grading device of  claim 12 , wherein the base is substantially planar. 
     
     
         14 . The screed grading device of  claim 1 , wherein the base includes an adhesive on a lower surface thereof. 
     
     
         15 . The screed grading device of  claim 14 , wherein the base includes double sided tape on a lower surface thereof. 
     
     
         16 . The screed grading device of  claim 1 , wherein the platform is pivotable relative to the base. 
     
     
         17 . The screed grading device of  claim 1 , wherein the base includes one or more supports, for supporting rebar above the substrate.
