Abstract
A piping joint for preventing pipe members laid across the connection end faces of two adjacent structural elements from being damaged by changes in the relative positional relationship between the two adjacent structural elements due to the expansion and contraction caused by changes in the temperature or external stresses. The piping joint connects the end portions of the two pipe members laid in two structural elements whose connection end faces can displace relatively to each other, between the connection end faces to make the two pipe members communicate. It comprises a fixed unit (30) fixedly embedded into the connection end face of one of the structural elements and a movable unit (50) supported by the fixed unit so as to be movable along the connection end face. The pipe member in the structural element is connected to the fixed unit, and the pipe member in the other structural element is connected to the movable element. The two pipe members communicate in the fixed unit. The stresses applied to the pipe members due to the relative displacements of the connection end faces of the two structural elements are absorbed by the displacements of the movable unit to the fixed unit along the connection end face.
