<p><P>PROBLEM TO BE SOLVED: To solve problems wherein the number of joints used is increased, efficiency of construction work is worsened, and required cost is increased because a pipe structure becomes three-dimensional and complicated when difference in axial position between a water supply main pipe and a water supply pipe occurs. <P>SOLUTION: A flow-in port 2A and a flow-out port 2B of the pipe joint 1 having horizontal connection ports (the inflow port 2A, outflow port 2B, connection ports 3A, 3B) formed in four sections at equal angle positions on the same plane and a vertical connection port (an upper connection port 3C) formed on at least an upper face crossing the plane on which they are arranged orthogonally are connected with the water supply main pipe (a main pipe Ps) or the water supply pipe (a branch pipe Pe), the connection ports 3A, 3B and the upper connection port 3C are connected with a branch pipe (a connection pipe Pr) or a plug (a stopcock S), and axes of the main pipe Ps, the branch pipe Pe, and the horizontal connection ports of the pipe joint 1 are arranged on the same plane. As a result, this pipe structure becomes plane and simple and can cope with change of design in the future, efficiency of construction work is improved, and cost required by construction work is reduced because difference in axial position among the main pipe Ps, the branch pipe Pe, and the horizontal connection ports of the pipe joint 1 does not occur. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
