TRANSPARENT FIRE-RESISTANT STRUCTURE Russian patent published in 2004 - IPC

FIELD: building units, particularly members for fire-resistant glazing of fire partitions and windows.

SUBSTANCE: transparent fire-resistant structure has casing formed as frame into which multi-chamber glass pack in placed. Glass packet is formed of silicate glasses spaced by spacers. Gaps between glasses are filled with gas. Structure has outer casing made as frame and at least one coupling member for frames connection. Inner frame has cover plates. Glass packet is placed between cover plates and inner casing frame. Coupling member is formed as bracket, which is fixed to outer frame and movably connected to inner frame. Gap is formed between inner and outer frames. Inner casing frame is connected with covering plate through thermal bridge made as sleeves. Glass packet includes at least 5 glasses connected in turns by frame-like spacers. Fire-resistant polymeric material layer is applied on adjoining surfaces of two glasses located at both glass packet sides. Gap between glasses from glass edges to frame perimeter is filled with sealant. Sealant and frame-like member located between two glasses arranged from two sides of glass pack are divided by layer of polymeric waterproof material.

EFFECT: increased heat insulation and fire-resistance along with reduced cost.
