Steel wooden heat preserving door
The invention relates to a steel wooden heat preserving door which comprises a steel door frame and a door leaf. Flame retarding and heat insulating pine skeletons and heat preserving filling materials are arranged in the door frame and the door leaf. Hinges and a lock are fixed to the front side of the door leaf. The door frame is formed by splicing a left border, a right border, an upper border and a lower border, wherein the left border and the right border are vertically arranged, and the upper border and the lower border are horizontally and transversely arranged. The cross section of the door frame is in a T shape protruding towards the inner side of the door frame. As the door frame is formed by splicing the left border, the right border, the upper border and the lower border, the left border and the right border are vertically arranged, and the upper border and the lower border are horizontally and transversely arranged, the door frame and the door leaf are matched through double groove faces, each groove face is provided with a row of sealing strips, step surface rabbets used for installing the sealing strips are formed in the rectangular periphery edge faces arranged on the inner sides of the step surfaces of the door leaf, the step surfaces of the upper and lower rabbets and the step surfaces of the left and right rabbets correspond to the step surfaces of the upper and lower borders and the step surfaces of the left and right borders respectively, the step surface of the lower rabbet is parallel to the step surface of the upper rabbet, and a side rabbet of the lock is provided with a slope and does not interfere with the door frame when used for opening the door leaf.
