部から熱風等が流出することがある。In the above conventional fireproof screen device, since the fireproof sheet is made of flame-retardant cloth, the fireproof sheet shields the shielded portion between the guide rails on both sides. In the event of a fire, the heat of the fire, such as hot air, causes the refractory sheet to shrink in the height direction of the refractory sheet, and the weight body is lifted by this refractory sheet, and an opening is made between the weight body and the floor surface. Hot air, etc. may flow out from the part. Further, when the refractory sheet receives wind pressure in a state where the shielded portion is shielded by the refractory sheet, the refractory sheet is bent, and the weight body is lifted by the refractory sheet. The space is opened, and hot air or the like may flow out from this opening.

ある。Therefore, the weight of the weight body is made heavy so that the weight body cannot be lifted to prevent the weight body from being lifted up. However, since the refractory sheet becomes large according to the opening of the shielded portion. However, there is a problem that the weight attached to the refractory sheet increases in weight depending on the size of the refractory sheet.

簡単に流出する、という問題が生じる。It is possible to pre-slacken the refractory sheet in consideration of the contraction amount of the refractory sheet or the bending amount of the refractory sheet which is bent by wind pressure when the refractory sheet is shielded by the refractory sheet. In this case, there arises a problem that outflow gaps are formed between both side ends of the refractory sheet in the width direction and the guide rails on both sides, and hot air or the like easily flows out from the outflow gaps.

である。The present invention has been made in view of the above problems, and when the sheet body shields the shielded portion, the sheet body is attached to the floor surface of the shielded portion when receiving pressure such as wind pressure. The lower end of the sheet body is pulled out from the weighted body on the floor, and the weighted body is not lifted by this sheet body and hot air etc. is prevented from flowing out between the weighted body and the floor surface. An object of the present invention is to provide a highly airtight screen device capable of reducing the weight of the weight body even if the sheet body becomes large according to the opening of the shielded portion.
