Abstract
A hanger for concrete walls, the joist hanger comprising a flat plate having a front surface and a back surface. A truss chord bracket or hanger that supports the bottom chord of a truss at the side of a building.
Description
TO WHOM IT MAY CONCERN:
Be it known that I, Carmen Gueli, a resident of the City of Saginaw, County of Saginaw, State of Michigan, a citizen of the United States of America have invented a new and useful device that is a JOIST HANGER/BRACKET
that is described in this specification.
BACKGROUND
Joist hangers are not new to the art. However, joist hangers that are imbedded into poured concrete for the purpose of retaining the joint support, increasing the strength of the overall structure are. Insulated concrete forms can be built quickly and efficiently. The present device improves the ability to increase efficiency. Prior art devices are limited in their application.
In United States Patent 8,051,620 entitled, "Joist Hanger for ICF Wall System" issued to Kittlitz on November 8, 2011 teaches a hanger for supporting joists or beams in insulated concrete formwork (ICF) systems that has two parallel side plates having inner and outer sections, plus an L-shaped support member comprising a horizontal leg extending between the lower edges of the outer section of the side plates, and an upward-extending vertical leg which demarcates the inner and the outer side plate sections.
The inner sections of the side plates are passed through slits in one insulation panel of the ICF wall forming system, until the support's vertical leg abuts the outer face of the insulation panel, leaving the side plate inner section extending partially into the formwork cavity.
The joist or beam to be supported may be set on the horizontal leg of the support member either before or after the concrete wall is cast.
Preferably, a cut out is made in the insulation panel behind the vertical leg of the support members to allow concrete to flow against the vertical leg and the supported joist or beam is cut for a close fit against the vertical leg such that external loads on the wall can pass into the joist or beam by direct compression.
The Kittlitz patent is limited by the required effort to thread the re bar through the opening in the part of the hanger that is within the forms. The present device allows for a quicker resolution by allowing the re bar to rest in the groove of the joist hanger portion imbedded within the poured wall and between the foam forms. The present device also has a plate between the hanger portion and the foam form for greater stability.
In United States Patent 6,845,954 entitled, "Pre-manufactured Joist and Beam Support for Concrete Walls", issued to Harber on January 25, 2005 teaches a pre-manufactured joist hanger and beam hanger support for concrete walls to be poured, particularly those utilizing a permanent, secondary non-structural material as forms essentially adjacent to the concrete, comprised of a U-shaped rigid member, rigid anchor members extending therefrom so as to cause a sufficiently large hole to be created in the secondary material in which the support is inserted and which essentially does not interfere with the flow of concrete being poured.
The Harber patent is limited, in that, it does not tie to any other structural item. It does not connect to any re-bar within the poured concrete and relies on the anchors to hold the compression weight to support the joist or

4 DETAILED DESCRIPTION OF THE DRAWINGS
Figure 1 shows the joist hanger 2 from the side within a poured wall 36. The flat plate 4 has a re-bar hanger 10 extending rearwardly from the back surface 8. The front surface 6 has the joist holder 12 extending forwardly from that front surface 6. The joist holder 12 consists of a first side 22 and a second side 24. The joist holder 12 also has a bottom 26 where a joist rests. Both the first side 22 and the second side 24 have openings therethrough 28 to secure the joist 38.
The back surface 8 of the flat plate 4 has the distal end 16 of the re-bar hanger 10 extending from it. The near end 14 of the re-bar hanger 10 has a first U-shaped portion 18 that supports re-bar 40. It has been discovered that the re-bar 40 can simply be placed in the first U-shaped portion 18 and the poured concrete 32 will retain it in place which adds to the structural integrity by receiving and transferring compression weight. There is a second U-shaped portion 20 that allows for extra reinforcement when a second re-bar 40 is added. This second re-bar 40 must be tied down with re-bar ties 34 to prevent movement of the re-bar 40 prior to the concrete pour.
The hanger 2 fits securely through an opening in the foam form 30. The flat plate 4 prevents movement during the pour process and reduces any leakage that may occur during the pouring or the concrete 32.
Figure 2 shows the joist hanger 2 from the top. The joist hanger 4 is on the front surface 6 of the flat plate 4. The re-bar hanger 10 is on the back surface 8 of the flat plate 4. The re-bar hanger 10 is slightly angled outwardly as it runs from its distal end 16 to the near end

9 The hangers 2 are manufactured for use in construction of wood and concrete. The first embodiment is placed through a layer of foam that is provided as a form to fill with concrete to create walls. The hangers 2 provide improved features like a rebar hanger 10 to provide additional strength for accepting and transferring compression stress. The re-bar hanger 10 also helps prevent pull out by having the ability to allow poured concrete to pass through it, thus providing a large concrete encased anchor.
The second embodiment is placed in the end cap of a pour wall to provide a truss support for securing joist.
The third embodiment is a truss chord bracket or hanger 2 that supports the bottom chord of the truss at the side of the building.
The joist hanger/bracket 2 also serves to replace hurricane straps and eliminate the need to use them. The joist hanger/bracket 2 are mounted before the concrete is poured. It has been discovered that the joist hanger/bracket 2 is more secured than any hurricane strap because it is now part of the structure instead of an added feature.
