Fireproof heat insulation door

Abstract

The invention discloses a fireproof heat insulation door which comprises a fireproof door body, wherein a concave cavity is formed in one side surface of the fireproof door body; an expansion body isbonded onto the bottom surface of the concave cavity; a floating door plate is installed onto the outer side end of the expansion body; the inner side end of the floating door plate is in contact withone side surface of the expansion body; a circle of clamp groove is formed in the outer side surface of the floating door plate in a way of surrounding the floating door plate for a circle; a water storage ring is arranged in the clamp groove; a hollow cavity is formed inside the floating door plate; a water storage bag is arranged in the hollow cavity; and the water storage bag is fully filled with water so that the water storage bag expands. The floating door plate can be ejected out after being heated; the floating door plate is used for blocking the flame, isolating a fire source and a heat source and prolonging the fireproof time; and additionally, the floating door plate which is ejected out can seal a door frame and isolate gaps to prevent smoke from going in or out of a room.

Description

technical field [0001] The invention relates to a door, in particular to a fire-proof and heat-insulating door. Background technique [0002] Fire doors of the prior art, these fire doors are used to isolate flames in case of fire. However, although the fire door has the ability to prevent fire, after all, there is only one solid door. After the door body is subjected to the long-term burning of the flame, the door body will still be damaged, and then the flame will enter another space, and the fire prevention time is not long. Moreover, since the door body is fireproof, many door slits will be formed on the outer wall surface of the door body. When the refugees take refuge, the smoke will enter the refuge place, causing the trapped people inside to suffocate because of the smoke, and its fireproof performance is average. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is a fireproof and heat insulation door, which can increas...

AI Technical Summary

Problems solved by technology

However, although the fire-resistant door has the ability to prevent fire, there is only one solid door after all. After the door body has been burned by the flame for a long time, the door body will still be damaged, and the flame will enter another space. The fire prevention time is not long

Moreover, because the door body is fireproof, but the outer wall of the door body will form a lot of door gaps, when the refugees take refuge, the smoke will enter the refuge, making the trapped people inside suffocate because of the smoke, and its fire performance is average.
