BAND-LIKE STEEL SHEET DOWEL AND SHAPE STEEL USING IT, AND COMPOSITE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a steel sheet dowel easy to manufacture, allowing a good yield of a material, and capable of simplifying its execution and to provide a shape steel beam using it and a structure of a composite beam. SOLUTION: Convex sections 3 and concave sections 4 having the same shape in a vertical inverse mode and continuously formed in turn in the axial direction X of a band-like steel sheet 2, and the head width of each convex section 3 is formed wider than its base width in this band-like steel sheet dowel 1.
