Abstract

The invention relates to a frame system composed of hollow steel pipe concrete integral joints and a construction method. The frame system composed of the hollow steel pipe concrete integral joints is formed by connecting composite columns with composite beams through the joints. The composite beams are horizontally arranged among the composite columns. The joints are outer sleeving integral type joints internally filled with high-strength concrete. The composite columns are sectional type hollow steel pipe concrete composite columns. The composite beams are sectional type external-prestressing honeycombed I-shaped beams. Beam connecting plates are arranged on the side faces of the two ends of the sectional type external-prestressing honeycombed I-shaped beams. Lower beam projecting plates are arranged at the lower ends of the beam connecting plates provided with bolt holes and further provided with prestressing tendon holes. Prestressing tendons are tensioned and anchored through the lower beam projecting plates. The joints are fixedly connected with the composite columns through upper connecting rings and lower connecting rings and connected with beam connecting plates of the composite beams through lower joint projecting plates. The problem of connecting complexity of the hollow interlayer steel pipe concrete columns and the beam joints is solved.

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...
