<p>PURPOSE:To always present constant fire preventing performance without presenting the condition of dispersion by mechanically pressurizing the side surface of a foaming body molding object, executing the exlargement and formation of a space part between an opening part, etc., and the foaming molding object, filling a fireproof filling material or a flameproof foamed molding body to the generated exlarging space part again and enclosing the space part. CONSTITUTION:An opening part 2 is bored to pass through a cable and an iron made sleve 3 is fitted to the internal surface of the opening part. Then, a lot of cables 4 are passed through the opening part and a bottom board, which is formed by a ceramic board, is set on the bottom board of the sleeve. After that, silicone foamed sticks 8, 8' and 8'' are stuffed into the opening part without intervals and the opening part is enclosed. Next, the side surface of the foamed stick is pressed by a presser 9 and a space part 10 is forcibly formed between the opening part and silicone foamed stick. Then, new silicone foamed sticks 11 and 11' are filled into the space part, which is formed in the above mentioned way, and the said space part is enclosed. After that, the said presser 9 is removed and a fire prevention measure is obtained.</p> |
