摘要： PROBLEM TO BE SOLVED: To provide required dimensional precision and effective tensile performance by providing an L-shaped reinforcing member butted to the connection part of a main girder and a joint plate from the inside, and connecting the L-shaped reinforcing member to the main girder by fillet welding. SOLUTION: This steel segment is formed of a main girder 3a, a joint plate 5, an L-shaped reinforcing member 12, a vertical rib 4, and a skin plate 6. The fillet weld 17 between the main girder 3a and the L-shaped reinforcing member 12 may be performed only in a sectional area necessary for transmitting the load of the main girder 3a. The fillet weld 17 between the outer main girder 3a and the L-shaped reinforcing member 12 is performed in the axial direction of the outer main girder 3a and in the axially right-angled direction of the main girder 3a. Therefore, since the load of the outer main girder 3a is transmitted to the adjacent segment through the L-shaped reinforcing member 12, sufficient resistant force can be provided to tensile force, and this segment is conformable even to the state where the tensile force by internal hydraulic pressure acts thereon. Accordingly, high tensile yield strength and rigidity can be provided, and the segment can be manufactured with high working precision.

摘要： PROBLEM TO BE SOLVED: To smoothly let the air out of an form when concrete is placed in the segment form using a steel shell segment. SOLUTION: An air vent pipe 26 is mounted to the upper part of the inside of a steel shell segment 21. One end of the air vent pipe 26 is located to a position near to the inside of an upper surface wall 24 of the steel shell segment 21 and is made to down from that position, and the other end passes under an inward flange 25. A front form 30 having a hole 32 for the front end of the lower side of the air vent pipe 26 to face thereto is mounted to the front of the steel shell segment 21, and an outside exhaust pipe is connected to the front end of the lower side of the air vent pipe 26. Concrete is placed from a concrete inlet 31. When concrete is placed. air in the form is exhausted to the outside from the air vent pipe 26 and outside exhaust pipe. Even if the steel shell segment 21 is provided with the inward flange 25 to the circumferential edge of the front opening, air is surely exhausted without being prevented from the inward flange 25, and a vertical casting system for casting concrete can be adpted by making the steel shell segment 21 as the vertical.
