ABSTRACT:
A pile joiner is disclosed for connecting together the ends of concrete piles which joiner includes a socket member and a mating member one of which is on the end of one pile and the other is on the end of the pile to be connected therewith. Each of these two members has a base plate with a central hole therethrough and a tubular element secured to each base plate and extending at right angles thereto. One tubular element is a socket element and the other is a mating element which is received within the socket element. The socket element and the mating element have at least a first sleeve means which includes a sleeve hole or holes through a wall or walls of each element and in alignment when the members are assembled together, an outer sleeve for each sleeve hole of the socket element extending outwardly and an inner sleeve for the sleeve hole or holes of the mating element extending inwardly or between sleeve holes in opposite walls thereof. When the two members are assembled together with their base plates in contact, the first sleeve means of each member or element are in alignment and receive a lock bar to retain the two members and their piles together against separation. Preferably the tubular socket element and the tubular mating element have a second sleeve means similar to the first which are in alignment when the two members are assembled together and preferably angularly located with respect to the first sleeve means. A second lock bar is received therein to additionally secure the the two members and the ends of the piles together. The pile joiner is constructed so that it is suitable for piles of different forms in cross section and for a wide range of sizes of piles. The invention includes each member individually as well as the members in combination as a pile joiner.
