A frame structure of a fireproof glass door is provided to increase critical limits of elasticity and elongation and to prevent the breaking of heatproof glass regardless of deformation and distortion by thermal expansion by installing the border of heatproof glass on a frame at the appointed interval. The frame structure of a fireproof glass door contains a support frame(10) provided with a primary insertion groove formed in the C-shape to house heatproof glass(G) and a movable frame and a pair of support projections projected to limit both sides of a movable frame placed in the primary insertion groove and split to tighten with a bolt(B), a reinforcement frame installed to the inside of the support frame to prevent sudden transformation caused by thermal expansion in a fire, a movable frame(20) installed in the primary insertion groove of the support frame and provided with a secondary insertion groove formed in the C-shape to house the border of the heatproof glass and a pair of support projections projected to support the border of the heatproof glass, a reinforcement frame installed tot he inside of the secondary support projection of the movable frame to keep the heatproof glass not to be separated by distortion or flexural deformation, and a space formed to absorb the flexural deformation of the movable frame and the heatproof glass inserted to the primary insertion groove and the secondary insertion groove against thermal expansion. |
