SOLUTION: During a drilling work to a steel plate 2, magnets 7 are magnetically attracted to the bottom surface of the steel plate and the fireproof sheet 3 is arranged in a suspended state. The magnet 7 is attached to the top end portions 5a of longitudinal frames 5, each frame 5 is attached in a rotatable manner to a hinge portion 10 located at the upper end portion of a support pole 9 and, when not used, the longitudinal frames 5 are collapsible through the hinge portion 10 in the direction of the support pole 9.
