The present invention provides a pipe connecting device. The pipe connecting device includes: a sleeve body; a flange unit; and a pocket body. The sleeve body includes a foaming agent accommodating space formed in a tubular shape with a through hole and installed on a mounting hole vertically penetrated through a concrete slab dividing floor sections in a building; an insertion unit protruding to the inner side of the through hole and opened to one side; and a hanging unit. The foaming agent accommodating space is formed on the side of an upper vertical pipe or a lower vertical pipe passing through the through hole, and a circumference thereof is enlarged. Also, one side of the foaming agent accommodating space is open, and a foaming fireproof filler is accommodated in the foaming agent accommodating space. The insertion unit has an insertion groove in which the upper vertical pipe or the lower vertical pipe coming in contact with the foaming fireproof filler is inserted. The hanging unit supporting the lower end of the lower vertical pipe or the upper vertical pipe inserted into the through hole. The pocket body is coupled to components for household branch and has a sliding pocket unit and a first coupling unit, wherein the sliding pocket unit is to enable the upper vertical pipe and the lower vertical pipe to be slid and separated from each other in order for an exposed length of the upper vertical pipe or the lower vertical pipe to be controlled. Therefore, the pipe connecting device has a structure in which the sleeve body and the pipe are integrally coupled without a gap. Therefore, the pipe connecting device can maintain stability by preventing shaking or a slip and can perform a certain fireproof function in a fire. The pipe connecting device enables a pipe work on a floor to be constructed by the sleeve body without the additional installation of a fixed clamp for fixing the vertical pipe, thereby improving workability and reducing the number of components to improve economic feasibility. |
