The present invention relates to a pipe connection device. Therefore, the pipe connection device according to the present invention, which is equipped between the end unit of a pipe in one side and the end unit of a pipe in the other side, comprises an expansion sleeve and a rubber band. The expansion sleeve is banded and wound so that the end unit of one side of a sleeve band can be folded toward the outside of the end unit of the other side. A joint unit is equipped in the end unit of one side of the sleeve band and the outside of the end unit of the other side. The joint unit is coupled with a fixing piece with a female screw outside the end unit of one side of the sleeve band. A pressing piece with a pressing hole is combined to the outside of the end unit of the other side of the sleeve band. A sleeve screw is inserted into the female screw of the fixing piece so that the pressing piece can be inserted into the pressing hole. The rubber band touches the outside of the sleeve band in order to be inserted into the inner circumferential surfaces of the pipes in one and the other sides. A sleeve screw of the joint unit is expanded. Therefore, the rubber band is pressed in the inner surfaces of the pipes in one and the other sides while being expanded. Accordingly, the present invention facilitates on-site construction, thereby shortening a construction period, and facilitates manufacturing operations. Also, the present invention prevents the generation of interference between pipe connection devices, thereby enabling to smoothly perform storage, loading, and transporting operations, and extends the lifespan by preventing transformation or damage. |
