<p>The present invention relates to a connector improving watertightness and stiffness by connecting high-rigidity drainpipes with an eco-friendly property and a manufacturing method thereof. The present invention is capable of stably maintaining watertightness and providing a strong coupling force in the connector connecting a cross-shaped reinforcement or a high-rigidity drainpipe to one side front end. The present invention comprises: a pressure wheel wherein a rubber ring is coupled to a pressure wheel connection portion of the connector; an inner profile having a through-hole and the cross-shaped reinforcement; an outer profile extrusion molding four surfaces of the inner profile to have the same thickness; and the drainpipe molding an outer diameter coating portion to an outer diameter of the outer profile. The high-rigidity drainpipe composed of the pressure wheel is connected to the connector improving watertightness and stiffness, and the connector has H-shaped reinforcement protrusions at constant intervals on the outer diameter to improve stiffness.</p> |
