A prefabricated assembly dry-type connection frame structure system and its construction method

Abstract

The invention discloses a prefabricated dry-type connecting frame structure system and a construction method thereof. The prefabricated dry-type connecting frame structure system comprises a structural column, a frame beam and a prefabricated hollow floor. The structural column is formed by splicing a set of column assembling units, and the column assembling units are connected through inter-column connecting parts. Embedded parts are respectively embedded in the top and the bottom of the column assembly units; each embedded part comprises an embedded plate, a shear-resistant insertion cylinder and a steel bar connector; a cross-shaped hole is formed in the middle of each embedded plate; each inter-column connecting part comprises a top plate, a bottom plate, a vertical supporting plate and a shear key, wherein the shape of the shear key is matched with that of the corresponding cross-shaped hole; the frame beam comprises a concrete beam body, and concrete protrusions are arranged on the top face of the concrete beam body. Beam main reinforcements are arranged in the concrete bulges, and the two ends of the beam main reinforcements exceed the end surfaces of the concrete bulges; connecting ribs are arranged in the column assembly units; and the connecting ribs are welded with the beam main ribs. The technical problems that wet operation exists in construction of a traditional fabricated structure system, on-site formwork erecting is needed, the structural anti-seismic property is poor, joint connection is unreliable, construction is complex, and safety is low are solved.

Description

technical field [0001] The invention belongs to the field of prefabricated construction engineering, in particular to a prefabricated and assembled dry connection frame structure system and a construction method thereof. Background technique [0002] my country is a country with many islands, and many islands are scattered in the vast sea area. The development of islands has important support significance for the development of my country's marine resources. At present, my country mainly focuses on the development of coastal islands (islands less than 10 km away from the mainland) and near-shore islands (islands between 10 and 100 km away from the mainland). The development involves very little, and the far-shore island is far away from the mainland. The transportation of energy, fresh water, and living materials for construction personnel is deeply affected by natural weather, and the island is often subject to severe weather such as typhoons. Therefore, the rapid constructi...
