Claims

[Claims for Utility Model Registration] 1. A pipe made of FRP in which a female screw is carved into the inner circumferential surface of the tip of the tube, and a vertical groove is provided on the inner circumferential surface leading to the tip of the tube. A male screw is carved on the outer circumferential surface of the tip of the body, and a vertical groove or a flat part is provided on the outer circumferential surface, and an annular groove is provided on the outer circumferential surface at a position above the groove or the flat part. It consists of an FRP tube provided with a protrusion and a flexible rod-shaped body, and the male and female threads of the tube are screwed together to form a concave groove and a concave portion of the tube. The rod-shaped body is inserted into a gap formed by aligning the groove or the groove and the flat part so that they face each other, so that the upper end of the rod-shaped body is positioned on the lower surface side of the annular protrusion. Characteristic pipe connection structure. 2. Claim 1, wherein the flat portion is formed by dividing the circumference of the outer peripheral surface of the tube into three equal parts.
Connection structure of the described pipe body. 3. The tube connection structure according to claim 1, wherein a plurality of concave grooves are provided in the circumferential direction of the tube body having the female thread and the tube body having the male screw. 4. The groove position of the groove provided in the tube body having a female screw and the groove provided in the tube body having a male screw is
4. The tube connection structure according to claim 3, wherein the tube connection structure is provided at unequal intervals in the circumferential direction.
