Abstract

The invention discloses a fireproof door cover seam arrangement device based on a water-based steel structure in the technical field of fireproof door cover seams. The fireproof door cover seam arrangement device comprises two fireproof door bodies, wherein a cover seam arrangement device is mounted on the door body section at a door seam of each of the two fireproof door bodies; each cover seam arrangement device comprises a cover seam frame, a fastening piece and a cover seam assembly; each cover seam frame comprises a C-shaped groove frame as high as the corresponding fireproof door body; amounting groove communicating with a groove cavity of each C-shaped groove frame is formed in the top end of the C-shaped groove frame; and a groove cover is embedded into the groove cavity of each mounting groove. Through cooperation of a steel belt and a rotating rod, front-back displacement of a cover seam plate can be realized, so that the sequence of closing a certain door body first is avoided when the double-opening type fireproof door bodies are closed, that is, people can conveniently select one door body for closing first, the situation that the cover seam plate hinders closing of the door body is avoided, and negative effects caused by the fact that the cover seam plate hinders closing of the door body are avoided.

Description

technical field [0001] The invention relates to the technical field of fire door cover seams, in particular to a fire door cover seam arrangement equipment based on a water-based steel structure. Background technique [0002] The fireproof door cover seam plate is a long fireproof board specially set at the middle seam of the double fire door, which is the same height as the door leaf. Its function is to strengthen the sealing performance of the door seam, prevent the smoke from spreading and the fire tongue from penetrating through the seam. It is widely used in double-leaf fire doors for safe passages such as shopping malls, office buildings, and exhibition centers. [0003] When the double-opening fire doors are closed, the cover seams of the two door bodies are stacked together in a front and back shape. Though effectively preventing and controlling smog and flame from penetrating through the gap, the switching mode of the two door bodies of the double door is also limi...
