A fire resistant frame structure for a facade or glass roof, includes a column profile, and a beam profile connectable to the column profile to form a support construction and so positioned relative to the column profile as to form spaces for receiving fire protection glasswork. The column profile and the beam rofile are each made of aluminum and comprised of a supporting core member for receiving static loads, an enclosure surrounding the core member, connecting members joining the core member to the enclosure at formation of a hollow chamber, and adsorbent material received in the hollow chamber and having heat absorbing and hydrophilic properties. The connecting members are formed by bridge members which provide a low heat conductivity to effect a low heat flux from the enclosure to the core member. Thus, crystal water can be released when the adsorbent material is subject to a certain temperature level to thereby cool the metallic framework.

[ What is claimed is:] [1.] A fire resistant frame structure for a facade or glass roof, comprising a first structural element; and a second structural element connectable to the first structural element to form a support construction and so positioned relative to the first structural element as to form bays for receiving a fire-proof glasswork, each of said first and second structural elements being made of aluminum and comprised of a supporting core member for receiving static loads, an enclosure surrounding the core member, connecting means for joining the core member to the enclosure such that a hollow chamber is formed between the core member and the enclosure, and adsorbent material received in the hollow chamber and having heat absorbing and hydrophilic properties, wherein the connecting means provide a low heat conductivity to effect a low heat flux from the enclosure to the core member, wherein the connecting means include bridge members which demarcate the hollow chamber, each said bridge member being provided on its hollow chamber distal side with a groove having a bottom which is formed by at least part of the bridge member, said bottom of the groove being formed with a plurality of spaced punched holes, with webs being formed between successive punched holes to ensure a reduced heat flux from the enclosure to the core member.
