From destal of junction structure and junction manner, and concrete steel compound truss bridge null metal tubing component

摘要

PROBLEM TO BE SOLVED: To provide a connection method and a structure of a concrete member and a steel pipe member which is simple in the structure and excellent in a fatigue-resistant property and has no structural weak point and also provide a concrete-steel composite truss bribe making use of the connection structure. ;SOLUTION: A part of a bar-form steel member 23 is inserted in the inside of a steel pipe member 21 from the end of the steel pipe member 21 to be connected to a concrete member 11, and a filling material 24 is charged into the part. The filling material 24 is cured to firmly stick to the bar-form steel member 23. The concrete member 24 is formed so that the end of the steel pipe member 21 butts the concrete member and the bar-form steel member 23 projected from the end of the steel pipe member 21 is embedded in the concrete member 11. And hence, the tensile force acting on the steel pipe member is transmitted to the concrete member by the adhesive force between the filling material and the steel pipe member, and the filling material and the bar-form steel member and concentration of stresses is not brought in the steel pipe member or the bar-form steel member.;COPYRIGHT: (C)1999,JPO
