Claims

[Scope of utility model registration request]

It is constructed by combining an upper mold body and a lower mold body which are divided into two parts, and attaches the upper mold body and lower mold body to the existing piping by sandwiching them. A split type branch pipe joint for taking out a branch pipe from a mold body, which includes a peripheral surface sealing material between the outer peripheral surface of the existing pipe and the inner peripheral surfaces of both the upper mold body and the lower mold body, and the upper mold, In addition to interposing joint surface sealing material between the joint surfaces of both lower mold bodies,
Furthermore, on the inner peripheral surfaces of both the upper and lower mold bodies,
A split type branch pipe joint characterized in that a tapered surface is formed along the axial direction of the existing piping, and a pipe movement prevention mechanism is interposed between the tapered surface and the outer peripheral surface of the existing piping.
