Abstract

A screed post assembly which may be easily and quickly interfaced to a Nelson stud extending upwardly from a horizontal support beam used in the construction of a building framework. The screed post serves as a support for a screed support system which is used to conduct a leveling operation for a concrete pour during the formation of a composite deck. The screed post assembly is also adapted to be extendable over a rebar member and used in the assembly of a protection device which covers the top, exposed ends of a plurality of linearly aligned, upwardly extending rebar members.

Claims

1. A rebar protection device for covering the top, exposed ends of a plurality of linearly aligned rebar members extending vertically upwardly from a support structure, said protection device comprising:

at least two screed post assemblies, each of said assemblies comprising;

an elongate, tubular screed post having upper and lower ends, said lower end being sized to receive the top end of a respective one of said rebar members; and

a support channel disposed on the upper end of the second post in a manner wherein said support channel substantially caps and covers said upper end;

a rail member sized and configured to be slidably receivable into and to extend between the support channels of said screed post assemblies;

the lower ends of said screed posts being extended over a pair of said rebar members with the top ends of the pair being abutted against the support channels when fully received into the screed posts, said support channels being oriented on said upper ends such that said rail member covers the top ends of each the remaining rebar members when received into the support channels.

2. The device of claim 1 wherein said support channel of each of said screed post assemblies comprises:

a middle portion having a generally planar upper surface and a lower surface, the top end of a rebar member of the pair being abutted against said lower surface when fully received into the screed post;

a first flange portion extending perpendicularly from said upper surface of said middle portion, said first flange portion having a generally planar first inner surface; and

a second flange portion extending perpendicularly from said upper surface of said middle portion, said second flange portion having a generally planar second inner surface substantially parallel to said first inner surface of said first flange portion;

said upper surface, said first inner surface and said second inner surface defining a generally U-shaped recess for slidably receiving said rail member.

3. The device of claim 1 wherein said support channel is threadably connected to said upper end of said screed post.

4. The device of claim 3 wherein at least a portion of said upper end of said tubular screed post is internally threaded, and said middle portion of said support channel includes a threaded member extending downwardly from said lower surface thereof which is threadably receivable into said upper end.

5. A rebar protection device for covering the top, exposed ends of a plurality of linearly aligned rebar members extending vertically upwardly from a support structure, said protection device comprising:

at least two screed post assemblies, each of said assemblies comprising an elongate, tubular screed post having upper and lower ends, at least a portion of said upper end being internally threaded and said lower end being sized to receive the top end of a respective one of said rebar members, and a support channel threadably connected to the upper end of said screed post, said support channel comprising;

a middle portion having a generally planar upper surface and a lower surface;

a first flange portion extending perpendicularly from said upper surface of said middle portion, said first flange portion having a generally planar first inner surface;

a second flange portion extending perpendicularly from said upper surface of said middle portion, said second flange portion having a generally planar second inner surface substantially parallel to said first inner surface of said first flange portion; and

a threaded member extending downwardly from the lower surface of said middle portion which is sized and configured to be threadably receivable into said threaded upper end;

said upper surface, said first inner surface and said second inner surface defining a generally U-shaped recess;

a rail member sized and configured to be slidably receivable into the generally U-shaped recesses of the support channels of said screed post assemblies;

said screed port assemblies being extended over a pair of rebar members such that said rail member covers the top ends of each of the remaining rebar members when received into the U-shaped recesses of the support channels.

6. A rebar protection device for covering the top, exposed ends of a plurality of linearly aligned rebar members extending vertically upwardly from a support structure, said protection device comprising:

at least two screed post assemblies, each of said assemblies comprising an elongate, tubular screed post having upper and lower ends, at least a portion of said upper end being internally threaded and said lower end being sized to receive the top end of a respective one of said rebar members, and a support channel treadedly connected to the upper end of said screed port, said support channel comprising;

a middle portion having a generally planar upper surface and a lower surface;

a first flange portion extending perpendicularly from said upper surface of said middle portion, said first flange portion having a generally planar first inner surface;

a second flange portion extending perpendicularly from said upper surface of said middle portion, said second flange portion having a generally planar second inner surface substantially parallel to said first inner surface of said first flange portion;

and a threaded member extending downwardly from the lower surface of said middle portion which is sized and configured to be threadably receivable into said upper end, said threaded member being operable to plug the upper end of said screed post when threadably received thereinto;

said upper surface, said first inner surface and said second inner surface defining a generally U-shaped recess;

a rail member sized and configured to be slidably receivable into the generally U-shaped recesses and extend between the support channels of said screed post assemblies;

the lower ends of said screed posts being extended over a pair of said rebar members with the top ends of the pair being abutted against the threaded members when fully received into the screed posts, said support channels being oriented on the upper ends such that said rail member covers the top ends of each of the remaining rebar members when received into the U-shaped recesses of the support channels.
