Abstract
Abstract A tie beam or girder assembly for exterior building face construction includes a core formed by resiliently joined aluminum sections 1, 2, an intermediate layer of fire-resistant material 13, 23, 29, and a surrounding outer facing 14, 16, 20, 28 of steel plate. Resilient mounting strips 10, 11 are provided for securing windows 7 or facing panels 27 to the assembly between flanges 8, 9 extending from the sections and gripping strips 12.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
146 words
A tie beam assembly comprising: a core section consisting of at least two tie beam sections, means for interfittingly connecting said sections together for displacement relative to each other, an inner steel plate facing, an outer steel plate facing and said steel plate facings covering all exposed surfaces of said tie beam sections, at least one preformed element and at least one integral element carried in spaced opposed fashion on at least one unexposed surface of said tie beam sections for mounting panels, panes of glass and the like on at least one side of said tie beam assembly, said tie beam sections being formed of aluminum, means for sealing said tie beam sections together at said interfitting means, and a fire-resistant material provided on the inner side of said steel plate facings and acting as a fire protective means for the aluminum tie beam sections.
Claim 2
Dependent Claim
146 words
A tie beam assembly comprising: a core section consisting of at least two tie beam sections, means for interfittingly connecting said sections together for displacement relative to each other, an inner steel plate facing, an outer steel plate facing and said steel plate facings covering all exposed surfaces of said tie beam sections, at least one preformed element and at least one integral element carried in spaced opposed fashion on at least one unexposed surface of said tie beam sections for mounting panels, panes of glass and the like on at least one side of said tie beam assembly, said tie beam sections being formed of aluminum, means for sealing said tie beam sections together at said interfitting means, and a fire-resistant material provided on the inner side of said steel plate facings and acting as a fire protective means for the aluminum tie beam sections.
Claim 3
Dependent Claim
41 words
A tie beam assembly as claimed in claim 1, wherein retaining elements provided on at least one of the tie beam sections and an interposed packing retains the outer steel plate facing mounted to said at least one tie beam section.
Claim 4
Dependent Claim
32 words
A tie beam assembly as claimed in claim 2, characterized in that the fire-resistant material provided between the tie beam sections (1, 2) and the steel plate facing comprises an asbestos layer.
Claim 5
Dependent Claim
24 words
A tie beam assembly as claimed in claim 1, wherein a snap connection connects the side steel plates facing with respective tie beam sections.
Claim 6
Dependent Claim
55 words
A tie beam assembly as claimed in claim 4, further comprising packing strips carried by said preformed elements for mounting said panes of glass and the like, and wherein reinforcing pieces are mounted to the packing strips for joining the side steel facing to the tie beam sections and comprise portions of said snap connections.
Claim 7
Dependent Claim
30 words
A tie beam assembly as claimed in claim 1, wherein the fire-resistant material provided between the inner and side steel plates and the tie beam sections are of U-shaped cross-section.
Claim 8
Dependent Claim
64 words
A tie beam assembly as claimed in claim 6, wherein said opposing, preformed and integral elements support a panel which is coupled to one side of said interfitting tie beam sections, and wherein fire-resistant material is provided on said panels with the fire-resistant material of U-shaped cross-section interposed between the inner steel plate and the side steel plate overlapping that provided on said panels.
