Abstract
A fireproof, heat-insulating slat consists of a pair of slat members having the same structure and disposed in the opposite directions. An enclosed space is formed between the pair of slat members. A first upper shoulder and a first lower shoulder are formed on the top end of the slat from the left to the right, and a second lower shoulder and a second upper shoulder are formed on the bottom end of the slat from the left to the right. An upper hinge and a lower hinge part are formed on the first lower shoulder and the second lower shoulder, respectively, and the upper hinge part and the lower hinge part are bent toward the first upper shoulder and the second upper shoulder, respectively. The enclosed space is filled with a fireproof, heat-insulating material.

A slat member (100), with a top end configuration and a bottom end configuration formed by bending a top portion and bottom portion of an elongated sheet respectively, the slat member (100) comprising:
- an upper shoulder (101) and a recess 102, formed on the top end of the slat member (100), the recess (102) being formed on one side of the upper shoulder (101) and lower than the upper shoulder (101);
- an upper hinge part (103), extending upward from the recess (102) a first predetermined distance and bent toward the upper shoulder (101) to shape a first hook;
- a lower shoulder (104), formed on the bottom end of the slat member (100) corresponding to the upper shoulder (101);
- and
- a lower hinge part (105), extending downward from the lower shoulder (104) a second predetermined distance shorter than the first predetermined distance and bent toward a direction away from the lower shoulder 104 to shape a second hook.
