Abstract
Abstract A 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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
124 words
An integral bridging element for interconnecting spaced parallelly arranged longitudinal structional members such as joists, roof rafters and studding comprising: a pair of spaced parallelly arranged members, a cross brace disposed between and attached to the ends of each of said members, means extending laterally outwardly of at least one end of each of said members for extending over exterior edges of a pair of the structural member, aperture means in said means for use in affixing said means to the structural members, and a beam member extending between the other ends of said members, whereby the briding element spaces and holds the structural members in place relative to each other during assembly and substantially reduces lateral warpage or deflection under normal building loads.
Claim 2
Dependent Claim
124 words
An integral bridging element for interconnecting spaced parallelly arranged longitudinal structional members such as joists, roof rafters and studding comprising: a pair of spaced parallelly arranged members, a cross brace disposed between and attached to the ends of each of said members, means extending laterally outwardly of at least one end of each of said members for extending over exterior edges of a pair of the structural member, aperture means in said means for use in affixing said means to the structural members, and a beam member extending between the other ends of said members, whereby the briding element spaces and holds the structural members in place relative to each other during assembly and substantially reduces lateral warpage or deflection under normal building loads.
Claim 3
Dependent Claim
169 words
An integral bridging element for interconnecting and applying supporting stress to spaced longitudinal juxtapositioned structural members such as joists, roof rafters and studding comprising: a substantially rigid first beam member for fixedly securing to and being supported at its ends by the exterior edges of a pair of structural members, aperture means formed in the ends of said first beam member for aiding in securing it to each of the structural members, and a pair of spaced parallelly arranged support members extending laterally outwardly of said first beam member from the same side thereof one adjacent each end thereof, a cross brace disposed between and attached to each of said support members, said support members being juxtapositioned with the sides of each of the structural members, and a second beam member extending between the free ends of said support members, whereby the bridging element spaces and holds the structural members in place relative to each other during assembly and substantially reduces lateral warpage or deflection under normal building loads.
Claim 4
Dependent Claim
169 words
An integral bridging element for interconnecting and applying supporting stress to spaced longitudinal juxtapositioned structural members such as joists, roof rafters and studding comprising: a substantially rigid first beam member for fixedly securing to and being supported at its ends by the exterior edges of a pair of structural members, aperture means formed in the ends of said first beam member for aiding in securing it to each of the structural members, and a pair of spaced parallelly arranged support members extending laterally outwardly of said first beam member from the same side thereof one adjacent each end thereof, a cross brace disposed between and attached to each of said support members, said support members being juxtapositioned with the sides of each of the structural members, and a second beam member extending between the free ends of said support members, whereby the bridging element spaces and holds the structural members in place relative to each other during assembly and substantially reduces lateral warpage or deflection under normal building loads.
Claim 5
Dependent Claim
25 words
The bridging element set forth in claim 2 wherein: the ends of said second beam member extend over the exterior edges of the structural members.
