Claims

[Scope of utility model registration request]

In a concrete pipe branch pipe joint that connects a branch pipe to the side of a concrete main pipe, there is a core pipe with a branch pipe attached to the base end, a flange provided on the outer peripheral surface of the tip of this core pipe, and a flange attached to the flange. and a gasket which is attached to the core pipe with its rear end locked and is press-fitted into the side opening hole of the concrete main pipe, and the diameter of the flange is smaller than the diameter of the side opening hole of the concrete main pipe. A joint for a branch pipe for a concrete pipe, characterized in that the flange portion is provided with a pair of tongue pieces that protrude in the same direction as the axial direction of the concrete main pipe and are engaged with the outer peripheral surface of the concrete main pipe.
