COMPOSITE PILE Russian patent published in 1995 - IPC

Abstract RU 2045623 C1

FIELD: civil engineering. SUBSTANCE: composite pile comprises jointed sections provided with embedded parts and positioned so as to form clearances between their ends, and connecting members holding together the embedded parts of the jointed sections. The composite pile is characterized in that each joining member has the form of a cover plate secured to the embedded parts of joined sections by a pair of studs one of which has a cone-shaped head and a cylindrical threaded stem while the other one has a cylindrical threaded head and a conical stem. The cover plate has holes for studs, one of said holes being conical to receive the cone-shaped head of one stud while the other one is of a cylindrical threaded shape to receive the head of the other stud. The embedded parts of the sections being joined have, respectively, a cylindrical threaded hole coaxial with the conical hole in the cover plate, and a conical hole coaxial with the cylindrical threaded hole in the cover plate. There are clearances between the embedded parts and the facing surfaces of the stud heads. EFFECT: higher reliability of the joints under dynamic forces applied during jointing, primarily of reinforced-concrete piles. 1 dwg
