    摘要: A stress transmission device arranged between a pile head of a foundation pile and an upper structural portion for transmitting stress between the foundation pile and the upper structural portion, to a structure which employs such a stress transmission device, and to a method of constructing such a structure. In the figures, a pile head member 5 is provided to the pile head 2a of the foundation pile 2, a structure support member 6 is fixed to an upper structural portion 3, and these mutually contact one another in the vertical direction via a first contacting surface 11 which defines a portion of a first imaginary spherical surface Sv1. And a prestressing steel rod 7 is fitted to the pile head member 5 and the structure support member 6 for holding them together in contact while pressing them together via the first contacting surface 11.

    摘要: The inner surface of the open end of a socket for a pipe is formed with a taper portion and a lock ring is received on the inner periphery of the taper portion. The outer peripheral portion of the socket corresponding to the taper portion is tapered in the same direction so that the wall thickness of the socket at the taper portion has a suitable value. When a pull-out force acts on a spigot inserted in the socket, the wedge action of the taper portion presses the lock ring against the spigot, whereby the separation is prevented. If an excessive pull-out force acts thereon, the portion of the socket which has the suitable thickness is deformed for radial expansion so as to allow the pull-out of the lock ring. Thereby, the pipe joint and the pipe body are prevented from being broken by the excessive force.
