することができる。[Function] According to the present invention, a flame-retardant laminated sheet in which a flame-retardant foam sheet is laminated on one side of a flame-retardant rubber sheet is wrapped around a cable shelf, and the periphery is roughly fixed with shape-memory alloy fittings. In this case, the flame-retardant foam sheet expands due to the heat generated during the spread of the fire, and at the same time the shape-memory alloy metal fittings deform, which eliminates the gap between the cable and the flame-retardant laminated sheet and prevents the supply of oxygen. It is possible to prevent the spread of fire to the cable.

The figure shows a flame-retardant foam sheet 3 on one side of a flame-retardant rubber sheet 2.
This figure shows an example of a flame-retardant laminate sheet 1 formed by laminating the following. In addition, as shown in the figure, a combustible foam material sheet 4 may be further laminated so that the flame retardant foam material sheet 3 is easily foamed by heating when the cable fire spreads. The flame-retardant laminated sheet 1 thus created is wrapped around the cable shelf 7 on which the cable 6 is laid, with the flame-retardant foam sheet 3 facing inside, and then the shape memory alloy metal 5 is wrapped around the cable shelf 7 on which the cable 6 is laid. FIG. 2 shows a state in which the flame retardant laminated sheet 1 is fixed by attaching the flame retardant laminate sheets 1 at appropriate intervals.

ることができる。Note that FIG. 3 shows the state of the cable shelf 7 after the fire has spread, to which the fire spread prevention method has been applied. As shown in the figure, the flame-retardant foam sheet 3 foams due to the heat generated during the spread of the fire, and at the same time the shape-memory alloy metal fitting 5 deforms, eliminating the gap between the cable 6 and the flame-retardant laminated sheet 1, thereby causing oxygen can effectively prevent the spread of fire in the cable 6.
