Anchor for a concrete floor

Abstract

An anchor for connecting a concrete layer to timber supports in building. The anchor has a first portion and an intermediate section disposed between upper and lower edge margins dividing a height of the first portion into thirds. The first portion can extend between two adjacent members of the timber supports into the concrete layer of the floor. The first portion may have a plurality of openings to receive fasteners to attach the first portion to one of the two adjacent members to attach the anchor to the timber supports. A second portion of the anchor extends from the upper edge margin in a first direction that is transverse to the first portion, and is configured to be spaced apart from the timber supports and embedded within the concrete layer to attach the anchor to the concrete layer.

What is claimed is: 
     
         1 . An anchor for connecting a concrete layer of a floor to a cellulosic layer of the floor, the cellulosic layer comprising a plurality of cellulosic members joined together in a side-by-side arrangement, the anchor comprising:
 a first portion having a height extending between a top and a bottom of the first portion, the first portion being configured to extend between two adjacent cellulosic members of the plurality of cellulosic members of the cellulosic layer, the first portion including a plurality of openings having uniform dimensions and configured for receiving fasteners to attach the first portion to one of the two adjacent cellulosic members of the cellulosic layer to attach the anchor to the cellulosic layer, the openings extending along at least 60% of the height of the first portion; and   a second portion extending from the upper edge margin in a first direction that is transverse to the first portion, the second portion configured to be spaced apart from the cellulosic layer and embedded within the concrete layer of the floor to attach the anchor to the concrete layer, the second portion including a plurality of openings having uniform dimensions and configured for receiving concrete ties in order to secure rebar to the second portion.   
     
     
         2 . The anchor as set forth in  claim 1 , wherein the openings in the first portion are circular. 
     
     
         3 . The anchor as set forth in  claim 2 , wherein the openings in the second portion are circular. 
     
     
         4 . The anchor as set forth in  claim 3 , wherein the openings in the second portion have a larger diameter than the openings in the first portion. 
     
     
         5 . The anchor as set forth in  claim 1 , wherein the opening in the first portion have a staggered arrangement. 
     
     
         6 . The anchor as set forth in  claim 5 , wherein the openings in the second portion are centered on a common axis. 
     
     
         7 . The anchor as set forth in  claim 1 , further comprises a transition between the first and second portions, wherein the transition comprises a rounded bend. 
     
     
         8 . The anchor as set forth in  claim 7 , wherein the anchor consists of only the first portion, the second portion, and the transition between the first and second portions. 
     
     
         9 . The anchor as set forth in  claim 1 , wherein the second portion has a width that is at least 70% of a height of the first portion. 
     
     
         10 . The anchor as set forth in  claim 9 , in combination with the concrete layer, wherein the second portion is embedded in the concrete layer. 
     
     
         11 . The anchor as set forth in  claim 1 , wherein the openings in the first portion extend along at least 65% of the height of the first portion. 
     
     
         12 . The anchor as set forth in  claim 1 , in combination with the cellulosic layer, wherein the first portion is attached to the cellulosic layer. 
     
     
         13 . An anchor for connecting a concrete layer of a floor to a cellulosic layer of the floor, the cellulosic layer comprising a plurality of cellulosic members joined together in a side-by-side arrangement, the anchor comprising:
 a first portion having opposite upper and lower edge margins and an intermediate section disposed between the upper and lower edge margins dividing a height of the first portion into thirds, the first portion configured to extend between two adjacent cellulosic members of the plurality of cellulosic members of the cellulosic layer into the concrete layer of the floor, the first portion including a plurality of uniform openings configured to receive fasteners to attach the first portion to one of the two adjacent cellulosic members of the cellulosic layer to attach the anchor to the cellulosic layer, the openings being disposed in the upper and lower edge margins; and   a second portion extending from the upper edge margin in a first direction that is transverse to the first portion, the second portion configured to be spaced apart from the cellulosic layer and embedded within the concrete layer of the floor to attach the anchor to the concrete layer.   
     
     
         14 . The anchor as set forth in  claim 13 , wherein the second portion includes a plurality of openings configured to receive concrete ties to secure rebar to the second portion. 
     
     
         15 . The anchor as set forth in  claim 13 , wherein the openings in the second portion are circular. 
     
     
         16 . The anchor as set forth in  claim 15 , wherein the openings in the second portion are centered on a common axis. 
     
     
         17 . The anchor as set forth in  claim 13 , in combination with the cellulosic layer. 
     
     
         18 . The anchor as set forth in  claim 17 , in combination with the concrete layer.
