Bracket for concrete forms

Abstract

The present invention provides in one aspect for a bracket for use with insulated forms for concrete walls. The bracket has an attachment plate for overlying the exterior of the insulated form to provide for a means of attaching the header or rim joist to the bracket. The bracket is provided an anchoring plate extending from the attaching plate for insertion into the interior of the insulated form. The present invention also provides for a method of attaching a header or rim joist to a concrete wall formed using insulated forms. The method involves cutting a vertical slot in the insulated form and inserting a bracket into the slot. The bracket has an attachment plate for overlying the exterior surface of the insulated form and an anchoring plate extending from the attachment plate through the slot into the interior of the insulated form. Concrete is poured into the form and allowed to set, after which the header or rim joist is attached to the brackets.

1 . A member for use with forms of insulation panels having an interior into which concrete is adapted to be poured to form an insulated concrete wall and an exterior, said member comprising a unitary metal body adapted to support a load, said body having an anchoring portion for insertion through the forms and into the interior of the forms to be embedded in concrete when concrete is poured into the interior of the forms, and a load supporting portion for location at the exterior of the forms after said anchoring portion has been inserted into the forms.  
   
   
       2 . A member as claimed in  claim 1  in which said anchoring portion has at least one hole or slot therethrough through which concrete can flow.  
   
   
       3 . A member as claimed in  claim 2  in which said anchoring portion has a plurality of holes or slots therethrough.  
   
   
       4 . A member for use in supporting floor structure joists for use with forms of insulation panels having an interior into which concrete is adapted to be poured to form an insulated concrete wall and an exterior, said member comprising a unitary metal body, said body having a planar anchoring portion for insertion through a slot provided in the forms and into the interior of the forms to be embedded in concrete when concrete is poured therein and a load supporting portion for location at the exterior of the forms after said anchoring portion has been inserted into said forms.  
   
   
       5 . A member as claimed in  claim 4  in which said anchoring portion has at least one hole or slot therethrough through which concrete can flow.  
   
   
       6 . A member as claimed in  claim 5  in which said anchoring portion has a plurality of holes or slots therethrough.  
   
   
       7 . A member as claimed in  claim 6  in which said planar anchoring portion is adapted to be inserted into the interior of said forms in a vertical position, said anchoring portion further having an upper edge provided with one or more recesses to receive and support one or more steel reinforcing bars.  
   
   
       8 . A member as claimed in  claim 7  in which said load supporting portion has a tab extending perpendicular to said planar anchoring portion to engage the exterior of the form when said anchor portion has been fully inserted into the interior of the form.  
   
   
       9 . A method of attaching a member having a planar anchoring portion and a load supporting portion to a concrete wall constructed using insulated forms having an interior to receive concrete and an exterior whereby said member is adapted for use in supporting a floor structure joist, the method comprising cutting a vertical slot in the insulated form prior to concrete being received into the interior thereof, inserting said planar anchoring portion of said member through the slot with the load supporting portion of said member located at the exterior of the forms, pouring concrete into the forms and allowing the concrete to set to anchor said member anchoring portion in the concrete whereby said load supporting portion is anchored for use in supporting a floor structure joist.  
   
   
       10 . A method as claimed in  claim 9  wherein said planar anchoring portion has a centrally located opening through which the concrete can flow.  
   
   
       11 . A method as claimed in  claim 10  wherein said opening is of a size to allow two steel reinforcing bars placed in side-by-side relationship to pass therethrough.  
   
   
       12 . A method as claimed in  claim 11  wherein said anchoring portion is provided with recesses along the top and bottom edges for supporting steel reinforcing bars.  
   
   
       13 . A method as claimed in  claim 12  wherein said load supporting portion is provided with at least one extension wing extending from the load supporting portion perpendicular to the anchoring portion where the anchoring portion joins the load supporting portion for supporting the insulated panels during the pouring of the concrete.
