Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.
As shown in figure 1, the fire proof seal system of steel first class fire resistant doorsets of the present utility model, including：It is arranged at fire resistant doorsets
Door leaf open side edge crack between a door and its frame cover plate, the crack between a door and its frame cover plate includes the bedplate 5 being fixed on door leaf 2, is arranged on bottom
Outer buckle 3 and the PLASTIC LAMINATED 4 being made up of thermal expansion material being filled between bedplate 5 and outer buckle 3 on the outside of seat board 5.
Wherein, the bedplate 5 is taken the shape of the letter U on the whole, and the outer buckle 3 takes the shape of the letter U, and the bedplate 5 is opened with outer buckle 3
Mouth is relative, and the bedplate 5 is inserted in outer buckle 3, forms the sky of filling thermal expansion material between bedplate 5 and outer buckle 3
Between.The base of the bedplate 5 preferably bends stepped.
