Abstract
A one-piece cross brace or bridging member for parallel structure beams, such as joists, studs, rafter trusses and the like which spaces and holds them in place relative to each other during assembly, and under normal building load conditions holds them in place longitudinally and prevents or greatly reduces lateral warpage or deflection thereof.
Claims9
An integral bridging element for interconnecting spaced substantially parallelly arranged longitudinal structural members such as joists, roof rafters and studding comprising:
- an elongated thin, flat, rigid strip,
- a part of each of the opposite ends of said strip being bent into a plane normal to the plane of said ends and at a distance spaced from the associated end of said strip to form abutment flanges substantially parallel to each other spaced apart a distance equal to the desired distance between adjacent structural members,
- the portion of said stip between said ends being bent longitudinally thereof to form a reinforced web,
- means formed in each of said ends for use in fastening the bridging element to the associated structural members,
- said part of each of the opposite ends of said strip comprising a tab formed by at least one cut extending into and through the end of said strip longitudinally thereof and through a predetermined distance, and
- said tab being normal to the surface of said end to provide the abutment flange.

- means formed in each of said ends for use in fastening the bridging element to the associated structural member,
- said part of each of the opposite ends of said strip comprising a tab formed by two spaced cuts extending into and through the end of said strip longitudinally thereof a predetermined distance, and
- said tab being bent normal to the surface of said end to provide the abutment flange.

- means formed in each of said ends for use in fastening the bridging element to the associated structural members,
- said part of each of the opposite ends of said strip comprising a tab formed along one side of the end of said strip, and
- a second part formed along each of said ends,
- said second part being bent normal to the surface of said end to provide a second flange for engaging the surface of the associated structural member opposite to the surface of the structural member engaged by the abutment flange formed at said end.
