The present invention relates to a through-wall pipe connecting device which is installed at a through-hole penetrating a wall to fix and connect a through-wall pipe penetrating the through-hole. The present invention provides the through-wall pipe connecting device including: a first and a second sleeve part at which one through-hole of the wall is installed, and which include a first and a second insertion space having a first and a second through-hole penetrated by the through-wall pipe in a tube shape and having a diameter expanded to an inserted side and having one side opened, a first and a second sleeve body having diameters expanded to another side and having a first and a second foaming agent accommodation space formed to be opened at another side, a first and a second foamed fire proofing filling material accommodated in the first and the second foaming agent accommodation space, and a first and a second flange part combined with the first and the second sleeve body to close the first and the second foaming agent accommodation space; and a control pipe which is connected to each of the first sleeve part and the second sleeve part by being inserted into each of the first insertion space and the second insertion space facing the first and the second sleeve part in a pipe shape, and is formed to have setting length in correspondence to the thickness of the wall. The first and the second sleeve body, the first and the second foamed fireproofing filling material and the first and the second flange part are packaged to form the first and the second sleeve part. Therefore, since the foamed fireproofing filling material is accommodated in the sleeve body and the sleeve part including the flange part is manufactured by being packaged at a factory, the sleeve part can be installed at the through-hole simply at the spot. Thus, the through-wall pipe connecting device of the present invention can be constructed very easily and can reduce construction costs. |
