The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a board is sewed up to fire door's lid of steel, lid seam board includes bottom plate and apron, and the bottom plate includes first U-shaped portion and second U-shaped portion, and first U-shaped portion and second U-shaped portion set up side by side and the opening is opposite, first U-shaped portion and the door leaf rigid coupling of fire door, and the apron lock of the shape of falling U is on the bottom plate.
Adopt above-mentioned technical scheme the utility model discloses compare with prior art, beneficial effect is:
form sealed cavity between bottom plate and the apron, prevent that the bottom plate from being heated and warp, increased the sealed effect that the board was sewed up to the lid, bottom plate and apron support mutually, have increased the intensity that the board was sewed up to the lid, have increased the use practical life who prevents fire door.
Further, the utility model discloses an optimization scheme is:
the joint of the first U-shaped part and the second U-shaped part is provided with a protruding part which is arranged in the opening direction of the second U-shaped part.
The first outer vertical plate of the first U-shaped part is in a shape of 5, and the second outer vertical plate of the second U-shaped part is provided with an undercut structure.
The end of the left vertical plate of the cover plate is provided with a hook-shaped structure, the hook-shaped structure is arranged on the inner side of the left vertical plate, the end of the right vertical plate of the cover plate is provided with a U-shaped structure, and the U-shaped structure is arranged on the inner side of the right vertical plate.
The hook-shaped structure of the cover plate is matched with the first outer vertical plate of the first U-shaped part, and the U-shaped structure of the cover plate is matched with the undercut structure of the second U-shaped part.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
Referring to fig. 1, a seam covering plate of a fire door made of steel is composed of a bottom plate 1 and a cover plate 2, wherein the bottom plate 1 and the cover plate 2 are made of thin steel plates and are formed by punching or rolling. As shown in FIG. 2, the bottom plate is composed of a first U-shaped part 1-1 and a second U-shaped part 1-2, and the first U-shaped part 1-1 and the second U-shaped part 1-2 are arranged in parallel and have opposite openings. A convex part 1-3 is processed at the joint of the first U-shaped part 1-1 and the second U-shaped part, the convex part 1-3 is arranged in the opening direction of the second U-shaped part 1-2, and the convex part 1-3 is arranged on the side surface of the door leaf, so that the sealing performance and the strength are improved. The first outer vertical plate 1-4 of the first U-shaped part 1-1 is in a shape of 5, and the second outer vertical plate 1-5 of the second U-shaped part 1-2 is provided with an undercut structure 1-7. The bottom of the first U-shaped part 1-1 is provided with a connecting hole 1-6, the first U-shaped part 1-2 is fixedly connected with a door leaf of the fireproof door through a bolt, and a sealing strip is arranged between the first U-shaped part 1-2 and the door leaf.
The cover plate 2 is buckled on the bottom plate 1 (shown in figures 1 and 3), the cover plate 2 is inverted U-shaped, a hook-shaped structure 2-2 is processed at the end part of a left vertical plate 2-1 of the cover plate 2, the hook-shaped structure 2-2 is arranged on the inner side of the left vertical plate 2-1, the angle of the hook-shaped structure 2-2 is an acute angle, a U-shaped structure 2-4 is arranged at the end part of a right vertical plate 2-3 of the cover plate 2, and the U-shaped structure 2-4 is arranged on the inner side of the right vertical plate 2.
