1. Field of the Invention
The present invention is directed generally to the field of building construction and, more particularly, to connections between a non-load bearing stud wall and a mounting track that is secured to an overhead structure.
2. Related Art
A typical wall to overhead structure connection is an inverted U-shaped longitudinal mounting track or slip track that receives studs between the legs of the U-shaped track. A wall cladding member is attached to at least one side of the studs. One of the legs of the mounting track is received between the studs and the wall cladding material. A top surface of the studs and wall cladding member are spaced from the overhead structure in order to allow for settling or other movement of the overhead structure (sometimes referred to as the roof or floor deck) with respect to the wall.
Various structures and materials may be used to seal the space between the top surface of the studs and wall cladding member and the overhead structure for purposes of providing an appropriate fire rating. Known sealing structures and materials have several drawbacks. For example, the use of a sealant and filling material is typically useful for very small gaps in applications where small amounts of movement between the overhead structure and the wall are possible. A sealant and filling material is susceptible to deterioration and fatigue over repeated cycles of movement, which may result in loss of the necessary fire rating. Known sealing structures, such as the slip track assembly disclosed in U.S. Pat. Nos. 5,471,805 and 5,755,066, are complex systems that require large amounts of material at a relatively high cost. Thus, a simple, cost effecting sealing structure that provides an appropriate fire rating and provides a positive attachment between the studs and the mounting or slip track would be an important advance in the art.
The present invention is directed to a wall fastener for use between a stud and a mounting or slip track. The wall fastener supports first and second wall cladding members and orients the wall cladding members relative to each other to provide a continuous wall cladding structure between the stud wall and the overhead structure to which the mounting track is secured. The wall fastener includes a first portion having first and second opposed primary surfaces and first and second sides. The first portion is secured to the mounting track with the first primary surface facing the mounting track and the second primary surface facing the first wall cladding member. The wall fastener also includes a second portion having a third primary surface that extends parallel to the first primary surface and is offset from the second primary surface a predetermined distance. The second portion is secured to the second wall cladding member with the third primary surface facing the second wall cladding member thereby positioning the second wall cladding member adjacent to the first wall cladding member. The wall fastener further includes a first fastening structure secured to the first side of the first portion. The first fastening structure slidingly engages the stud thereby retaining the wall fastener to the stud while providing for a sliding movement of the wall fastener relative to the stud.
Another aspect of the present invention is directed to a method of retaining a stud to a mounting track with a fastener such that the mounting track is vertically movable relative to the stud wall. The fastener includes a first portion having a first primary surface and first and second sides, and a fastening structure extending from the first side of the first portion. The method includes securing the first portion to the mounting track with the first primary surface facing the mounting track, and slidingly securing the fastening structure to the stud wall thereby retaining the stud wall to the mounting track so as to prevent lateral movement of the fastener relative to the stud wall while permitting vertical movement of the fastener relative to the stud wall.
A yet further aspect of the present invention is directed to a method of forming a wall fastener from a single piece of material. The wall fastener retains a stud wall to a mounting track and to support a secondary wall cladding member in engagement with a primary wall cladding member of the stud wall. The method includes forming a first portion that includes first and second opposed primary surfaces and first and second sides. The first portion is secured to the mounting track with the first primary surface facing the mounting track and the second primary surface facing the primary wall cladding member. The method further includes forming a second portion that includes a third primary surface that extends parallel to the first primary surface and is secured to the secondary wall cladding member, and positioning the secondary wall cladding member adjacent to the primary wall cladding member, forming a third portion that extends between the first and second portions, and forming a first fastener structure along the first side of the first portion. The first fastener structure is configured to engage a stud of the stud wall to retain the wall fastener to the stud wall while permitting vertical movement of the wall fastener relative to the wall.
Another aspect of the present invention relates to a wall fastener that is secured to a mounting track to support a secondary wall cladding member adjacent to a primary wall cladding member. The wall fastener includes a first portion having first and second opposed primary surfaces, the first primary surface defining a first portion plane, and the first portion being secured to the mounting track with the first primary surface facing the mounting track and the second primary surface facing the primary wall cladding member. A second portion of the wall fastener is spaced apart from the first portion a predetermined distance and includes third and fourth surfaces that extend parallel to the first surface. The second portion is secured to the secondary wall cladding member with the third primary surface facing the secondary wall cladding member and the fourth primary surface facing the first portion plane. A third portion of the wall fastener extends between the first and second portions to couple the first and second portions together, and a fourth portion of the wall fastener extends from the second portion in a direction toward the first portion plane and contacts the mounting track.
The present invention is also directed to a wall fastener configured to retain a stud wall to a mounting track, wherein the stud wall includes a plurality of studs and a primary wall cladding member secured to the plurality of studs. The wall fastener includes a first portion having first and second primary surfaces and first and second sides. The first portion is secured to the mounting track and is positioned between one of the plurality of studs and the primary wall cladding member with the first primary surface facing the mounting track and the one stud, and the second primary surface facing the primary wall cladding member. The wall fastener also includes a first fastening structure that extends from the first side of the first portion and retains the fastener to the one stud while providing sliding movement of the fastener relative to the one stud to provide vertical movement of the mounting track relative to the stud wall.
The present invention is also directed to a wall fastener configured to retain a stud wall to a mounting track, wherein the stud wall includes a plurality of studs and a primary wall cladding member secured to the plurality of studs. The wall fastener includes a first portion having first and second primary surfaces and first and second sides. The first portion is secured to the first side wall of mounting track with the first primary surface facing the outside surface of the first side wall and the second primary surface facing the first wall cladding member. The first portion also includes a first track retaining member that engages the inside surface of the first side wall.

The wall fastener 60, shown in
The second portion 64 of the wall fastener 60 is parallel but offset from the first portion 62 by a distance “D.” The second portion 64 defines third and fourth primary surfaces 72 and 74. The third portion 66 is horizontal and connects the top edge 75 of the first portion 62 to the bottom edge 73 of the second portion 64. The fourth portion 68 is horizontal and connects the top edge 71 of the second portion 64 with the top edge 69 of the contact member 70. The contact member 70 is in the same vertical plane as the first portion 60. The contact member 70 contacts the outside surface 55 of side wall 54 of the slip track 50 and provides extra support for the wall fastener 60 when the secondary wallboard member 40 is being secured to the third primary surface 72 of the wall fastener 60.
Primary wallboard member 32 is fastened to stud 20 with screws 94 or other conventional fastening means. Primary wall cladding member 32 is preferably gypsum board in large part due to its fire resistance properties. In that regard, it is understood that primary wall cladding member 32 may include multiple layers of wall material, for example, to create the required fire rating. The thickness of the primary wall cladding member 32 defines the distance “D” of the wall fastener 60. As stated above, stud 20 is spaced vertically lower than roof structure 10 a distance “S.” Likewise, primary wall cladding member 32 is spaced a distance “S1” from the overhead structure 10. Distance “S1” is typically several inches, but could be more or less depending on the application.
As mentioned above, the secondary wall cladding member 40 is attached to the third primary surface 72 of the fastener 60 with screws 92 or other conventional fastening means. Secondary wall cladding member 40 extends down from a top edge 42 that is adjacent to overhead structure 10 and overlaps in a sliding relationship with primary wall cladding member 32. Secondary wall cladding member has a vertical dimension “S2” which is greater than “S1” to provide overlap and ensure maintenance of the overlap for all expected relative movement between overhead structure 10 and the stud wall 30. The secondary wall cladding member 40 covers the space between the top end of primary wall cladding members 32 and the overhead structure 10. The secondary wall cladding member is preferably made of material similar to the material of the primary wall cladding member 32 and preferably has a similar thickness as primary wall cladding member 32 so as to provide a consistent fire rating.
