Abstract
Existing systems require the installation of joists directly to a partially cast hanger or bracket or to the joist hanger. The present disclosure is related to the brackets for use in ICF systems allowing joist hangers to be directly mechanically attached to brackets obviating the need for the use of ledgers. A bracket includes a plate having one or more anchor members extending from the plate for casting into an ICF wall. A method of assembling a bracket includes cutting a sheet of metal to define the plate and the one or more anchor members and bending the anchor members toward from the plate. A method installing joist hangers includes inserting anchor members of brackets into an ICF wall pre-casting and attaching joist hangers to the brackets post-casting.
Claims20
A bracket for attaching joist hangers to an insulated concrete form (ICF) wall comprising:
- a face plate having a top and a bottom edge, side edges, and a front and a back surface, the face plate having a longitudinal centerline extending from the top edge to the bottom edge;
- a first anchor member and a second anchor member extending from a common side edge of the face plate substantially perpendicular to the front surface of the face plate;
- a central anchor member extending from the common side edge of the face plate substantially perpendicular to the front surface of the face plate, the central anchor member between the first anchor member and the second anchor member;
- wherein:
- the first anchor member, the central anchor member, and the second anchor member are for insertion through an ICF panel of the ICF wall and into a formwork cavity of the ICF wall,
- the first anchor member, the central anchor member, and the second anchor member each have a respective longitudinal axis extending from the face plate to a tip of each respective anchor member, and a respective transverse axis perpendicular thereto,
- the transverse axis of the first anchor member is offset by a first angle from an axis of the longitudinal centerline of the face plate,
- the transverse axis of the second anchor member is at a second angle relative to the axis of the longitudinal centerline of the face plate, and
- the transverse axis of the central anchor member is parallel to the axis of the longitudinal centerline of the faceplate.
A method of manufacturing a bracket for attaching joist hangers to an ICF wall comprising
- providing a sheet of metal;
- cutting the sheet of metal to define a face plate having a longitudinal centerline extending from a top edge to a bottom edge of the face plate and a first anchor member, a central anchor member, and second anchor member, the first, central, and second anchor members extending from the face plate along a common side edge of the face plate and the central anchor member between the first anchor member and the second anchor member;
- and
- bending each of the first anchor member, the central anchor member, and the second anchor member along a respective fold line until the first, central, and second anchor members extend substantially perpendicularly from a common surface of the face plate, wherein the fold line of the first anchor member is angularly offset from the longitudinal centerline of the face plate, and wherein the fold line of the central anchor member is parallel to the longitudinal centerline of the face plate, and wherein the first, central, and second anchor members are for insertion through an ICF panel of the ICF wall and into a formwork cavity of the ICF wall.
A method of installing joist hangers on an ICF wall comprising:
- cutting slots in an ICF panel disposed around a formwork cavity, said slots sized for the insertion of anchor members of a pair of brackets therethrough, wherein at least one of the slots is cut at an angle that is offset from a vertical axis that is perpendicular to a ground level;
- inserting the anchor members through the slots such that they extend into the formwork cavity, and such that face plates of the pair of brackets contact the ICF panel;
- pouring concrete into the formwork cavity of the ICF wall;
- and
- attaching a joist hanger to the face plates of the pair of brackets.
An insulated concrete form (ICF) system comprising:
- an ICF wall comprising two ICF panels and a formwork cavity therebetween;
- and
- two brackets inserted through one of the two ICF panels of the ICF wall and into the formwork cavity of the ICF wall, the two brackets spaced apart at a distance from one another for attachment of a joist hanger to the two brackets, each of the two brackets comprising:
- a face plate having a top and a bottom edge, side edges, and a front and a back surface, the face plate having a longitudinal centerline extending from the top edge to the bottom edge, and
- a first anchor member and a second anchor member extending from a common side edge of the face plate substantially perpendicular to the front surface of the face plate, wherein:
- the first anchor member and the second anchor member are for insertion through one of the two ICF panels of the ICF wall and into the formwork cavity of the ICF wall,
- the first anchor member and the second anchor member each have a respective longitudinal axis extending from the face plate to a tip of each respective anchor member, and a respective transverse axis perpendicular thereto,
- the transverse axis of the first anchor member is offset by a first angle from an axis of the longitudinal centerline of the face plate, and
- the transverse axis of the second anchor member is at a second angle relative to the axis of the longitudinal centerline of the face plate.
The ICF system of 17, wherein the central anchor member has a longitudinal axis extending from the face plate to a tip of the central anchor member, and a transverse axis perpendicular thereto, said transverse axis being parallel to the axis of the longitudinal centerline of the faceplate.
