Description

Fireproof glass frame system of steel section bar Technical Field The invention relates to the field of doors and windows, in particular to a steel section fireproof glass frame system. Background The aluminum alloy door and window partition has the advantages of light weight, easy processing, strong durability, easy maintenance and the like in the market, but also has certain application defects, such as poor energy saving and heat preservation effects, unfavorable environmental protection, poor noise isolation effects, insufficient fireproof performance and the like, but the aluminum alloy door and window is more important in distinguishing whether a fire source comes from the outer side or the inner side, if the fire source comes from the inner side, the better the sealing effect of the window can cause choking death of internal people due to insufficient oxygen, and people in an internal room need to be protected from contacting smoke coming from the outside when the aluminum alloy door and window occurs outside, so that the aluminum alloy door and window needs to make targeted reactions aiming at different fire source directions. To this end, we propose a steel profile fire-resistant glazing frame system that solves the above-mentioned problems.
