Fireproof door leaf and manufacturing method thereof
The invention relates to the technical field of fireproof doors, in particular to a fireproof door leaf and a manufacturing method thereof. The fireproof door leaf comprises an outer plate and an inner plate. One long edge side of the outer plate is provided with a first folded edge, and the other long edge side of the outer plate is provided with a V-shaped folded edge. One long edge side of theinner plate is provided with a second folded edge, and the other long edge side of the inner plate is provided with an outer overturned edge. The outer plate and the inner plate are buckled together.The first folded edge is located at the outer portion of the second folded edge, the inner surface of the second folded edge is used for installing a strengthening plate through a connecting piece, and the outer overturned edge can be clamped and fixed into the V-shaped folded edge, and accordingly a cover gap plate can be formed. Through the arrangement of the inner plate and the outer plate, thestrengthening plate can be conveniently installed on the inner surface of the second folded edge through a connecting piece, then, buckling assembling is conducted, welding is not needed, and the outer space cannot be occupied; and meanwhile, the outer overturned edge is clamped and fixed into the V-shaped folded edge equivalent to a labyrinth seal structure, and therefore seal performance is guaranteed.
本发明涉及防火门技术领域，尤其是涉及一种防火门门扇及其制作方法。防火门门扇，包括外板和内板，外板的一个长边侧设置有第一折边，外板的另一个长边侧设置有V形折边；内板的一个长边侧设置有第二折边，内板的另一个长边侧设置有外翻边；外板与内板扣合在一起，其中，第一折边位于第二折边的外部，第二折边的内表面用于通过连接件安装加强板，外翻边能够夹紧固定在V形折边的内部，以形成盖缝板。通过设置内板和外板，便于先将加强板通过连接件安装在第二折边的内表面，然后再进行扣合装配，不需要焊接，也不会占用外部空间，同时，由于外翻边夹紧固定在V形折边的内部，相当于迷宫密封结构，保证了密封性。
