摘要： PROBLEM TO BE SOLVED: To provide sufficient joining strength of both steel bottom plate end parts 1a and 1a and a splicing plate 4; and to provide sufficient joining strength for the steel bottom plate end parts and concrete C.
SOLUTION: This joint part structure of a steel-concrete composition floor slab, is integrated by placing the concrete C by arranging reinforcements 3 on a steel bottom plate 1. Both steel bottom plate end parts and the splicing plate 4 are firmly joined by fastening to both steel bottom plate end parts 1a and 1a, by respectively screwing a nut 17 in a welding stud 16. A stud 15 with a swelling head part is arranged separately from this stud 16 by penetrating through the splicing plate 4. The swelling head part is formed by screwing a nut 19 in the tip of both studs 15 and 16, and the sufficient joining strength in the vertical direction of the steel bottom plate end parts and the concrete C, is provided by the head parts 19 and 20. The shearing key effect is exhibited by the concrete C entering clearance of a through-hole 22, to enhance joining force in the horizontal direction of the concrete C and the steel bottom plate end parts 1a. The respective studs 15 and 16 are arranged in a zigzag shape.
