Document Type and Number:
Japanese Patent JP2016089329
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a steel pipe connecting jig that allows an interval between connected steel pipes to be adjusted readily.SOLUTION: A steel pipe connection jig 1 is for connecting a lower pile 100 and an upper pile 110 made of steel pipes. The steel pipe connecting jig 1 includes a ring-form member 3 that is tightened and fixed on an outer peripheral surface at an upper part of the lower pile 100 and surrounds the outer periphery of the lower pile 100, a ring-form member 2 that is tightened and fixed on an outer peripheral surface at a lower part of the upper pile 110 and surrounds the outer periphery of the upper pile 110, and distance changing means 4 capable of changing a distance between the ring-form members 2 and 3. The distance changing means 4 adjusts a distance C (route interval Cr) between the upper pile 110 and the lower pile 100 at a plurality of locations in a circumferential direction of the upper pile 110 and the lower pile 100, by changing the distance between the ring-form members at a plurality of locations in a circumferential direction of the ring-form members 2 and 3.SELECTED DRAWING: Figure 8
