A bracket for use with insulated forms for concrete walls for attaching header or rim joists to the 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 with an anchoring plate extending from the attaching plate for insertion into the interior of the insulated form. A method of attaching a header or rim joist to a concrete wall formed using insulated forms is also provided. The method involves cutting a vertical slot in the insulated form and insterting 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.
A bracket for use with a form of spaced apart insulation panels defining a cavity into which concrete is to be poured, the bracket being adapted for attaching and supporting a joist the bracket comprising a unitary metal body having a rigidity and stiffness sufficient to support the load of a joist, the bracket having a rigid, planar attachment plate for location to the exterior of an insulation panel of the form to provide for a means of attaching joist to the bracket, and a rigid, planar anchoring plate extending from the attaching plate for insertion into the cavity of the form and having at least one concrete flow passage therethrough to provide a continuity of concrete through the anchoring plate when concrete is poured into the form, the bracket being an L-shaped bracket with the attachment plate forming the base of the L and the anchoring plate extending perpendicular from one edge of the attachment plate to form the leg of the L, wherein the attachment plate is provided with at least one extension wing extending perpendicularly from the anchoring plate to the opposing side of and in the same plane as the attachment plate to provide support to the exterior of the insulation panel.
A bracket as claimed in 1 wherein the unitary metal body is formed from a 14 to 16 gauge steel sheet.
A method of attaching a header or rim joist to a concrete wall constructed using a form of insulation panels into which concrete is to be poured, the method comprising cutting a vertical slot in the exterior of the insulation panel, inserting a bracket into the slot, the bracket being a unitary metal body having a rigidity and stiffness sufficient to support the load of a joist, the bracket having an attachment plate located to the exterior surface of the insulation panel and an anchoring plate extending from the attachment plate through the slot into the interior of and part way across the form and having at least one concrete flow passage to provide a continuity of concrete through the anchoring plate for embedment within the concrete, pouring concrete into the form, allowing it to set and attaching the joist to the brackets.
A building structure comprising a concrete wall constructed using insulated forms, the concrete wall including a bracket having a header or rim joist attached thereto, the bracket comprising a an L-shaped bracket of 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 an attachment plate forming the base of the L overlying the exterior of the insulated form to which the header or rim joist is attached, and an anchoring plate extending perpendicular from one edge of the attachment plate forming the leg of the L and extending into the interior of the insulated form and embedded within the concrete therein, the anchoring plate having an anchoring structure embedded within the concrete, the anchoring structures including a concrete flow passage providing a continuity of concrete through the anchoring plate.
A building structure as claimed in 15 wherein the unitary metal body is formed from a 14 to 16 gauge steel sheet.
