Summary: | The invention discloses a hollow slab hinge joint structure, a hollow slab beam and a construction method of the hollow slab hinge joint structure, and belongs to the technical field of hinge joint construction. A grouting seam, a first cavity hinging part, a middle grouting seam, a second cavity hinging part and a socket type connecting part are sequentially arranged in the hinge seam from top to bottom in a seam communication manner and are filled with a high-strength shrinkage-free cement grouting material; the first cavity hinge part and the second cavity hinge part each comprise a semicircular cavity groove formed in the side end face of the adjacent hollow slab in the longitudinal extension direction of the hinge joint, and the two semicircular cavity grooves are oppositely and symmetrically formed to jointly define a cylindrical cavity extending in the longitudinal direction of the hinge joint. A plurality of U-shaped steel bar rings are sequentially arranged in the two semicircular cavity grooves in t |
