Title:
MECHANICAL JOINT STRUCTURE FOR TUBULAR STEEL PILES
Document Type and Number:
WIPO Patent Application WO/2011/122349
Kind Code:
A1
Abstract:
Provided is a joint structure that mechanically joins two tubular steel pipes by fitting together an inner joint pipe and an outer joint pipe that are fixed by welding to corresponding end surfaces of the two pipes, and keeps the two joint pipes together by inserting pins. An outer joint pipe (3) having a plurality of connecting holes (3a...) made in the peripheral wall thereof in the radial direction is fixed by welding to the end surface of one of the tubular steel piles (1). An end mounting bracket (4) is affixed by welding to the corresponding end surface of the other tubular steel pile (2), and to the other side of the end mounting bracket (4) an inner joint pipe (5) having a plurality of connecting holes (4a...) made in the peripheral wall thereof in the radial direction at positions that correspond with the connecting holes (3a) in the outer joint pipe (3) is affixed by welding. The inner joint pipe (5) can fit into the inside of the outer joint pipe (3). The inner joint pipe (5) is inserted into the inside of the outer joint pipe (3), and the connecting holes (3a and 5a) of the outer joint pipe (3) and the inner joint pipe (5) are brought into alignment and a connecting pin (6) is inserted therein, and processing to prevent the pin from being dislodged is performed, connecting the two tubular steel piles (1 and 2).
