This application claims priority to Provisional Application No. 60/856,063, filed Nov. 2, 2006, which is incorporated herein in its entirety.
FIELD OF THE INVENTIONThe present invention relates to hangers, and more particularly to construction hangers that provide for increased strengthening of the structure the hanger is used for and provides for an enhanced structural integrity of the structure.
BACKGROUND OF THE INVENTIONHangers for construction purposes of various types are well known in the art. Such devices are typically used in the construction industry to join beams and/or columns to create a variety of different structures. They are used for commercial and residential building construction.
However, previous hangers have some inherent disadvantages. One of the disadvantages with existing hangers is that they do not supply sufficient strength in certain applications and often, too many of them are required which increases construction costs and time to build a structure. Another disadvantage is that they do not provide for flexibility of structures they are used in and do not provide for elasticity of joints and fasteners. Many of the existing hangers are also difficult to work with and expensive to manufacture.
The present invention overcomes these and other problems inherent in existing hangers. The present invention provides construction hangers that provide for increased strengthening of the structure and enhanced structural integrity. The hangers are less expensive to manufacture than most existing construction hangers and provide for ease of use in the field.
In one form, a construction hanger is provided that provides for the length of time to perform a certain project is substantially decreased, the costs associated with the work are also decreased and the overall strengthening of the structure is enhanced. The cantilever hangers introduce flexibility, elasticity of joints and fasteners and at the same time provide for the possibility of different alternative functions required for every building site. Further, since virtually every project requiring hangers uses between 10-30 hangers at a minimum, the low cost of production for high volume of hangers 10 will provide for additional profits.
In one application, the cantilever hangers may be used for floor joists, porch decks, ceiling joists, or roof joists. In one embodiment, a hanger for short segments of final floor joists or ceilings is provided. The hanger may be used for making the final parts of floors or ceilings by means of beams supported only on one side. The hangers enable overhanging of short beams. The hangers may be made of metal plate-gauge 1/16″, ⅛″, 3/16″ or other dimensions depending on expected load capacity.
BRIEF SUMMARY OF THE INVENTIONIn one form, a hanger is provided that can accept a construction member comprising two mounting plates each having an extension piece and a plurality of holes disposed on the mounting plates and extension pieces. Also provided is at least one joist plate connected to the mounting plates and extending outward to form an opening to accept at least one construction member and a plurality of holes disposed on the joist plate. Other embodiments provide for the joist plates to pivot about the mounting plates. Also, a swivel support may be movably attached and connect the joist plates at an end distal the mounting plates.
While the present invention is susceptible of embodiments in various forms, there is shown in the drawings and will hereinafter be described some exemplary and non-limiting embodiments, with the understanding that the present disclosure is to be considered an exemplification for the invention and is not intended to limit the invention to the specific embodiments illustrated. In this disclosure, the use of the disjunctive is intended to include the conjunctive. The use of the definite article or indefinite article is not intended to indicate cardinality. In particular, a reference to “the” object or “a” object is intended to denote also one of a possible plurality of such objects.

This system of cantilever hangers provides multiple benefits. For example, by using cantilever hangers 10, the length of time to perform a certain project is substantially decreased, the costs associated with the work are also decreased and the overall strengthening of the structure is enhanced. The cantilever hangers introduce flexibility, elasticity of joints and fasteners and at the same time provide for the possibility of different alternative functions required for every building site. Further, since virtually every project requiring hangers uses between 10-30 hangers at a minimum, the low cost of production for high volume of hangers 10 will provide for additional profits.
After joist 20 is inserted into an opening 12 of the cantilever hanger, holes 14 provide for fasteners to be inserted into the joist to maintain the joist in a fixed position within cantilever hanger 10. In one form, bolts, nails or screws may be used and inserted into holes 14 to secure the joist within cantilever hanger 10. In yet other embodiments, different fasteners may be used. Similarly, mounting plates 16 may be fixed to beam 22 by the use of bolts, nails, screws, or other fasteners. See, for example,
There are multiple applications for cantilever hangers 10,
Also shown are extension plates 44 having openings 45 whereby extension plates 44 are attached or formed as a unitary part of joist plate 32. One or more extension plates 46 connect plates 44 and are movably attached to plates 44 whereby a connector 47 (in one form a rivet) passes through opening 45. In one embodiment, the materials used for the hinge hangers may be zinc-coated sheet gauge 1/16″, ⅛″, 3/16″ or other gauges depending on expected load capacity. In yet other embodiments, different materials can be used.
During use, a joist 62 or other structural member is positioned within opening 33 so as to allow for the required angle between the joist and beam. Holes 34 provide for fasteners to be inserted into the joist to maintain the joist in a fixed position within hinge hanger 30. In one form, bolts, nails or screws may be used and inserted into holes 34 to secure the joist within hinge hanger 30. In yet other embodiments, different fasteners may be used. Similarly, mounting plates 36 may be fixed to the beam by the use of bolts, nails, screws, or other fasteners. See, for example,
As shown in
In one embodiment, a hinge hanger with only one wing may be supplied. This format could be used with joists for floors, ceilings, porch decks and other construction applications. In one form, the hanger may consist of the following parts: (i) one metal plate adherent to main beam hanging-top mount—for stronger support features; (ii) one “wing” metal plate joined as a hinge to provide for movement; (iii) at the wing there are two or more holders at the top and bottom to keep joists positioned within the metal plate, wing and holders and holes for nails or screws are provided; (iv) this embodiment may be used as single and/or left angle or right angle; and (v) the size of the hangers—height, width and additional elements can be adapted to the size of the beams, ceiling, floors or roof rafters-joists for a particular application.
Generally, in one form, a skew hanger is provided with a regulated angle of fastening of the two beams. It can be used with floors, ceilings, porch decks, etc. The raw material used may be zinc coated sheet gauge 1/16″, ⅛″, 3/16″ depending on expected load capacity. Steel or aluminum rivets, or other alloys rivets enabling hammering of nailheads in the heat after joining all the elements during the production process may be used. Steel rod (diameter ⅛″—or more depending on the size of the hanger and planned load capacity) may be used. At the end of the rod there may be a flat head in the upper portion. In one form, the hanger consists of the following parts: (i) two load bearing metal plates, adherent to mainbeam hanging—top mount or face mount; (ii) two “wing” metal plates joined in a hinge manner with load bearing metal plates; (iii) at the bottom of the “wing” metal plate there is a rectangular “foot” metal plate with a cut-out elliptic hole; (iv) both “wings” are jointed by means of a flat metal plate—“connector” with two rivets inserted in elliptic holes; (v) in the sides of the “wings” there are holes for screws, bolts or nails. For larger load capacity—there may be a screw joined to two rests which are cut in angular form to maintain the angle of junction; (vi) the weight of the beam inserted in the “hanger” is distributed over screws in side wings and on the main screw. “Connectors” supports the beam only while fitting; and (vii) the size of the hanger—height, width and additional elements will be adapted to accept and adapt to the size of the beams, ceilings or rafters.
