Although the technology to do so has been previously registered, on-site assembly is cumbersome because the upright pipe coupling unit is divided into a pair of unit plates, one side is bound by the first and second hinges, and the other side is fastened by bolts. Loss of parts occurs frequently, and due to the one-way bolting structure, there is a limit to increase the fixing force with the upright pipe.

In addition, in another prior art registration number 10-1514834, the through sleeve is configured to be separated into a lower pipe and an upper pipe; The lower pipe has a plurality of fixing brackets protruding from the outer periphery of the bottom of the lower body that penetrates up and down, and the lower expansion part is formed at the same height as the lower body in the middle and outside of the lower body, so that between the lower body and the lower expansion part. A pad indentation space is formed in the flame-blocking expansion pad, and several expansion pad expansion holes are formed at the upper end of the lower body facing the lower expansion part; The upper tube is formed so that the upper body is fitted to the lower body, a lid that is easily divided by a dividing groove is integrally formed at the upper part of the upper body, and the upper part is expanded to fit into the lower expansion part outside the lower part of the upper body. A technology in which a tube part is formed, and a locking frame is formed to protrude from the upper outer periphery of the upper expansion part so that it can be caught in the lower expansion part, and the upper pipe and the lower pipe constituting the through sleeve are formed in a circular or square shape. Although it has been previously registered, it may lead to damage due to the flow of the standing pipe due to external impacts such as earthquakes because the standing pipe is not firmly fixed.
