Description

FIELD OF THE INVENTION

The 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 INVENTION

Hangers 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 INVENTION

In 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.

DETAILED DESCRIPTION OF THE INVENTION

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.

In one form, as shown in FIGS. 1, 2 and 3, the invention is a cantilever hanger. 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 a metal plate-gauge 1/16″, ⅛″, 3/16″ or other dimensions depending on expected load capacity. The metal plate is bent into rectangular shape with a splice which enables pressure of the beam inserted in the hanger while hammering the nails or screwing in screws which fasten the beams to the hanger. In one embodiment, the hanger can be constructed from a single piece of sheet metal without the requirement of joining two or more pieces at a weld or seam. On one side of this rectangular shape two (2) wings adherent to the carrying beam (ridge beam-DBL Joister BEAM) are bent. The wings have upper splice on the carrying beam. They have top mount fastening features. The loading force of the beam is spread in groups by means of clockwise blocking hanger-top mount with additionally fixed wing and an upper splice which balances the stranding force. In some applications it is recommended to put joists every 12″ O.C. In one form, it is important to use ¾″ PLYWOOD hardware which is screwed into the beam provides for reinforcement of the spread layers. It is also important to ensure that the joist is adherent to the carrying beam. In that way the joist neutralizes the force from the final part of the carrying beam and the hangers only act to hold it in position. The size of hangers used depends on the final length and width of joists. In one application, it is recommended to use 3-4 maximum which enables a great variety of use.

As shown in FIGS. 1, 2 and 3, in one embodiment, cantilever hanger 10 may have an open end 12, load bearing mounting plates 16 having holes 14, and load bearing joist plates 18 having opening 19. In one embodiment, joist plates 18 (or wing) are formed to create hole 12 by adapting connector plate 24 as shown in FIG. 1. Plate 24 may be secured to plate 18 by, for example, welding or riveting. A joist 20 may be inserted into hole 12 to achieve a substantially snug fit of the joist 20 placed inside the cantilever hanger. Mounting plates 16 are formed to fit adjacent beams 22 as shown, for example, in FIGS. 3-7.

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, FIG. 3.

There are multiple applications for cantilever hangers 10, FIG. 4 shows an example of the cantilever hangers 10 being used to form a small balcony. FIG. 5 shows a roof being formed by a system of the cantilever hangers 10. FIG. 6 shows the curved end of a balcony being constructed by using cantilever hangers 10. FIG. 7 shows soffit construction formed by use of cantilever hangers 10. There are also many other applications and structures that can be created by use of cantilever hangers 10. For example, this embodiment may be used to provide additional support for larger joists.

FIGS. 8 and 9 show yet another embodiment of cantilever hangers 10 which may be used in applications that require additional mounting support for mounting plates 16. As shown in FIGS. 8 and 9, additional mounting plate extension pieces 17 may be placed so that they extend from mounting plate 16 to wrap around opposite side of beam 22 for yet increased strength and support of cantilever hanger 10. Extension pieces 17, also have one or more Holes 14 so fasteners can be inserted to attach the hanger 10 to Beam 22.

FIGS. 10-13 show hinge hangers 30. Hinge hangers 30 provide flexible, adjustable angle support for a variety of different joists, trusses and other structural members. As shown in FIG. 13, some examples of how hinge hangers 30 may be used are with standard wood joists, I-joists, floor trusses, roof trusses and other applications. As shown in FIGS. 10-12, one embodiment of hinge hanger 30 may include a joist plate 32 (or wing) having holes 34, whereby joist plates 32 form an opening 33. Also provided are mounting plates 36 having holes 38 and extending to form hinge portions 39.
