Abstract:
A dual-web H-shaped steel, and a connecting node of the dual-web H-shaped steel and a concrete precast slab. The dual-web H-shaped steel comprises two flange plates (1) and two webs (2), the two flange plates (1) being parallel to each other, the two webs (2) being parallel to each other, and the webs (2) being fixedly connected between the two flange plates (1) perpendicularly; the two webs (2) and the two flange plates (1) form a hollow cavity. The dual-web H-shaped steel is good in wholeness and has high rigidity, thereby facilitating connection between the dual-web H-shaped steel and a concrete precast slab.
