Hollow slab hinge joint structure, hollow slab beam and construction method of hollow slab beam
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 the longitudinal extending direction of the hinge joint in a staggered and opposite pre-buried mode at intervals and sequentially penetrate through and are hinged to full-length longitudinal steel bars extending in the longitudinal direction of the hinge joint in a sleeved mode. The hinge joint is compact in structure, stable in connection, stable in transverse connection and good in bending resistance and shearing resistance, and glue injection reinforcement in the operation period is facilitated.
本发明公开了一种空心板铰缝构造、空心板梁及其施工方法，属于铰缝施工技术领域，铰缝结构包括设置于相邻空心板之间的铰缝，铰缝内由上向下依次缝隙连通且填充高强无收缩水泥灌浆料的设置有注浆缝、第一腔铰连部、中部灌浆缝、第二腔铰连部和承插式连接部；第一腔铰连部和第二腔铰连部均包括分别沿铰缝纵向延伸方向开设于相邻空心板侧端面的半圆形腔槽，且两个半圆形腔槽相向对称共同围成一个沿铰缝纵向伸展的圆柱形空腔，两个半圆形腔槽内沿铰缝纵向延伸方向依次间隔交错且相向预埋设置有若干个U型钢筋环，且依次穿套铰接于沿铰缝纵向伸展的通长纵向钢筋上。本发明的铰缝结构密实、连接稳定，横向联系稳定，抗弯抗剪性好，且便于运营期注胶加固。
