Hanger for insulated concrete system and method of installation thereof and method of installing a retrofit hanger in an insulated concrete

Abstract

There is described a hanger for hanging an object from a composite wall. The composite wall has a concrete core, a foam outer wall and a second outer wall. The hanger comprises: a first plate having an embedded portion for retention within the concrete core and a hanging portion extending from the foam outer wall for connection to the object. The embedded portion having an edge in addition to its distal edge, the edge being substantially transverse to the longitudinal axis of the first plate. A method for installing the hanger is also described. The hanger is particularly well suited for hang a joist.

       5 . The hanger defined in  claim 4 , wherein the support has an aperture formed therein for receiving the securing means.  
   
   
       6 . The hanger defined in  claim 3 , wherein the support is a U-shaped bracket.  
   
   
       7 . The hanger defined in  claim 2 , wherein the hanging portion has an aperture for receiving the securing means.  
   
   
       8 . The hanger defined in  claim 3 , wherein the securing means secures the hanging portion, the support and the object together.  
   
   
       9 . The hanger defined in  claim 3 , wherein the support and the hanging portion each have a plurality of apertures therein for receiving the securing means, the apertures arranged such that the support can be secured at a number of angles.  
   
   
       10 . The hanger defined in  claim 1 , wherein the embedded portion has an aperture therein for improved retention in the concrete core.  
   
   
       11 . The hanger defined in  claim 1 , wherein the embedded portion has slots about its periphery.  
   
   
       12 . The hanger defined in  claim 11 , wherein the slots are sized to fit reinforcing bars.  
   
   
       13 . The hanger defined in  claim 1 , wherein the first plate has a projection extending therefrom substantially parallel to the composite wall.  
   
   
       14 . The hanger defined in  claim 13 , wherein the projection is adjacent the exterior of the foam wall.  
   
   
       15 . The hanger defined in  claim 13 , wherein the projection is adjacent the concrete core.  
   
   
       16 . The hanger defined in  claim 1 , wherein the hanger is formed of metal.  
   
   
       17 . The hanger defined in any one of claims  1 - 16 , wherein the hanger further comprises a second plate having an embedded portion for retention within the concrete core and a hanging portion extending from the composite wall, the object being connectable to both plates.  
   
   
       18 . The hanger defined in  claim 17  wherein the first plate and second plate are the same.  
   
   
       19 . The hanger defined in  claim 17  wherein the first plate and second plate are different.  
   
   
       20 . The hanger defined in  claim 17 , further comprising a member connecting the first plate and second plate.  
   
   
       21 . A method for installing a hanger on a composite wall formed from a foam wall and a second wall defining a cavity fillable with concrete, the hanger including a first plate having an embedded portion and a hanging portion, wherein the embedded portion comprises an edge in addition to its distal edge, the edge being substantially transverse to the longitudinal axis of the first plate, the method comprising the steps of: 
 (a) cutting a slit through the foam wall so that the slit extends to a hanging position;    (b) sliding the first plate in the slit to the hanging position, wherein the embedded portion of the first plate extends into the cavity and the hanging portion extends from the composite wall;    (c) pouring concrete into the cavity and allowing it to cure to form the composite wall.    
   
   
       22 . The method defined in  claim 21 , further comprising the step of securing a support for receiving an object to be hung to the hanging portion.  
   
   
       23 . The method defined in  claim 21 , further comprising the step of (d) sliding a second plate into a second slit before step (c) and positioning it substantially opposite the first plate, wherein an embedded portion of the second plate extends into the cavity and a hanging portion of the second plate extends from the composite wall.  
   
   
       24 . The method defined in  claim 23 , further comprising the step of (e) positioning the support between the hanging portions of the first and second plates and securing the support to the hanging portions of the first and second plates.  
   
   
       25 . A method of hanging a hanger from a foam wall of a composite wall having a cured concrete core and at least one foam outer wall, the hanger comprising a substantially L-shaped bracket having a retaining portion and a hanging portion for connection to an object to be hung, the hanging portion disposed at substantially a 90 degree angle to the retaining portion, the method comprising the steps of: 
 (a) forming a cavity at a hanging position in the foam wall to accommodate the retaining portion;    (b) securing the retaining portion to the concrete core.    
   
   
       26 . The method defined in  claim 25  further comprising the step of securing a support for receiving the object to the hanging portion.
