Abstract

The present invention relates to a frame system and a construction method composed of hollow concrete-filled steel tube integral joints. The frame system composed of hollow concrete-filled steel tube integral joints is composed of composite columns and composite beams connected through joints, and the composite beams are arranged horizontally between the composite columns. The joints are jacket integral joints filled with high-strength concrete; the composite column is a segmental hollow tubular concrete composite column, the composite beam is a segmental externally prestressed honeycomb I-beam, and the segmental externally prestressed honeycomb I-beam Both ends of the beam are equipped with beam connection plates, the lower end of the beam connection plate has a beam lower protrusion plate, bolt holes are set on the beam connection plate, prestressed tendon holes are also set on the beam lower protrusion plate, and the prestressed tendons are tensioned and anchored through the beam lower protrusion plate ; The node is fixedly connected to the composite column through the upper connecting ring and the lower connecting ring, and the node is connected to the beam connecting plate of the composite beam through the lower protruding plate of the node. The invention solves the problem of complex connection between the hollow interlayer concrete-filled steel tube column and the beam node.

Description

technical field [0001] The invention relates to a house frame structure in the field of civil and architectural structures, in particular to a frame system and a construction method composed of integral joints of hollow steel tube concrete. Background technique [0002] In the conventional reinforced concrete frame structure system, the frame joints are mostly reinforced concrete cast-in-place joints. This kind of reinforced concrete joints needs formwork, binding steel bars and then pouring concrete like frame beams and columns. Not only the bearing capacity of the components is low, but the construction period is long. Moreover, the nodes are prone to damage under the action of earthquakes. With the rapid development of the civil construction industry, the concrete-filled steel tube structure has been widely used. The hollow sandwich concrete structure is a new structural form based on the concrete-filled steel tube structure. The hollow sandwich concrete-filled steel tube...
