Abstract

The embodiment of the invention provides a fireproof building steel structure which comprises a fireproof outer shell, a fireproof inner core, fireproof covers, an ignition assembly and driving assemblies. The fireproof outer shell is slidably connected to the fireproof inner core; the ignition assembly is used for guiding flames to combustible tension cables which connect the fireproof inner corewith the fireproof outer shell so as to break the combustible tension cables, so that the fireproof inner core can close an inner cavity under self weight. The fireproof building steel structure canisolate safe areas from fire areas in time in the event of a fire, thereby avoiding the spread of fire and improving the safety.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a fireproof building steel structure. Background technique [0002] At present, in the field of construction, the steel structure itself is fireproof. However, the building structure is complex, and the outside and inside of the steel structure are equipped with combustible protective layers, and there are combustible materials indoors and outdoors. During a fire, if If the fire source is not isolated in time, it is easy to cause serious accidents. [0003] The study found that the current steel structure buildings have the following disadvantages in terms of fire protection: [0004] The vents are always open and cannot be closed in time when a fire occurs, which poses a great safety hazard. Contents of the invention [0005] The objectives of the present invention include, for example, to provide a fire-resistant building steel structure, which can isolate the safe area...
