ABSTRACT:
The present invention provides a pipe junction holder for connecting a pipe to a mechanical joint. The junction holder contains a wedge placed between a seal gland and a wedge gland. The wedge has a split opening along its outer sloped surface. The seal gland is adapted for connection to the mechanical joint and the wedge gland. The wedge gland is adapted to seat over the wedge and cause the wedge to clamp on the pipe when the wedge glang is connected to the seal gland. The inner surface of the wedge is designed to clamp along substantially the entire circumference of the pipe when the wedge is tightly held in place over the pipe. The invention also provides a method of joining pipes with mechanical joints, wherein a free end of the pipe is adapted to be seated in a socket end of the mechanical joint. The method comprises the steps of: (a) placing the free end of the pipe in the socket end of the mechanical joint; (b) placing a gasket in the socket end over the pipe for providing a seal between the pipe and the mechanical joint; (c) placing a seal gland adjacent to the gasket over the pipe and connecting the seal gland to the mechanical joint; (d) placing a ring wedge having a through split opening and an outer sloped surface over the pipe adjacent to the seal gland; and (e) placing a wedge gland having an inner sloped surface that is adapted to slide over the outer surface of the wedge when the wedge gland is urged over the ring wedge; and (f) connecting the wedge gland to the seal gland.
