Title:
JOINING STRUCTURE OF STEEL MATERIAL AND BUSHING USED FOR THE SAME STRUCTURE
Document Type and Number:
Japanese Patent JP3896179
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To execute easily steel material integrated joining work without demanding for troublesome work and contrive to definite stress transmission even when the relative positions of the mutually joined steel pipes are deviated.
SOLUTION: Penetration holes 9 and 10 are formed on connecting plates 7 and 8 at matching positions with steel shells 1A, 1A or connecting materials 3 respectively. A bushing 11 is fitted in the respective penetration holes 9 and 10. An insertion hole 13, which extends in the axial direction shifted to the rotary center, is formed in the bushing 11. When the bushings 11 and 12 are rotated, the absolute position of the insertion hole 13 varies, centering on the rotary center. Even when the positions between the penetration hole on the side of a segment and the penetration hoe of the connecting material 3 are deviated, it is possible to match the insertion holes 13 formed respectively by turning the bushings 11, 12 properly. A bolt is inserted into the insertion holes 13 so that the bolt may be fastened with a nut.
