Insulated concrete form wall having a bracket attaching a rim joist thereto

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.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 
     
         1 . A building structure comprising a concrete wall constructed using insulated forms having an interior containing concrete and an exterior, the concrete wall including a bracket having a header or rim joist attached thereto, the bracket comprising a unitary metal body being of a rigidity and stiffness sufficient to support the load of a floor through the header or rim joist, the bracket having a floor joist load supporting portion located to the exterior of the insulated form to which the header or rim joist is attached, and an anchoring portion extending from the floor joist load supporting portion and projecting a substantial distance into the interior of the insulated form and embedded within the concrete therein, the anchoring portion having an anchoring structure embedded within the concrete, the anchoring structures including a concrete flow passage providing a continuity of concrete through the anchoring portion. 
     
     
         2 . A building structure as claimed in  1  wherein the unitary metal body is formed from a 12 or 16 gauge steel sheet. 
     
     
         3 . A building structure as claimed in  claim 2  wherein the anchoring portion is generally U-shaped with two anchoring structures located at a top and bottom of the anchoring portion, each of the anchoring structures having a concrete flow passage comprising an opening through which the concrete passes. 
     
     
         4 . A building structure as claimed in  claim 3  wherein the each of the openings have steel reinforcing bars passing therethrough. 
     
     
         5 . A method of attaching a header or rim joist to a concrete wall constructed using insulated forms having an interior containing concrete and an exterior, the method comprising cutting a vertical slot in the insulated form, inserting a bracket into the slot, the bracket having a floor joist load support portion located to the exterior of the insulated form and an anchoring plate extending from the attaching plate and projecting a substantial distance through the slot and into the interior of the insulated form, pouring concrete into the form, allowing the concrete to set, and attaching the header or rim joist to the floor joist supporting portion of the bracket. 
     
     
         6 . A method as claimed in  claim 5  wherein the anchoring plate is generally U-shaped to provide for two anchoring structures located at the top of bottom of the anchoring plate. 
     
     
         7 . A bracket as claimed in  claim 6  wherein each of the anchoring structures are provided with a centrally located opening through which the concrete can flow. 
     
     
         8 . A method as claimed in  claim 7  wherein the opening is of a size to allow two steel reinforcing bars placed in side-by-side relationship to pass therethrough. 
     
     
         9 . A method as claimed in  claim 8  wherein the anchoring structures are provided with recesses along the top and bottom edges for supporting steel reinforcing bars.
