Abstract

The invention relates to a framework composed of prestressed composite beams of a system and a construction method thereof. The framework composed of the prestressed composite beams of the system is formed by connecting composite columns with the composite beams through joints. The composite beams are horizontally arranged between the composite columns. The joints are outer sleeve integrated joints filled with self-compacting concrete. The composite columns are sectional hollow tubular concrete composite columns. The composite beams are system prestressed honeycombed I beams with flanges being rectangular steel tube concrete. Prestressed tendons arranged in rectangular steel tubes in the lower flanges of the composite beams are located in lower reinforcing cavity annular plates and bypass joint outer tubes. The prestressed tendons are positioned through single-hole positioning plates and double-hole mainpositioning plates with holes and subjected to tensioning anchorage at joint end beams. The self-compacting fine aggregate concrete of the composite beams communicates with self-compacting fine aggregate concrete of the joint end beams. By adoption of the framework, the complexity problem of the connecting joints between the system prestressed I beams with the flanges being made of rectangular steel tube concrete and the hollow tubular concrete composite columns is solved.

Description

technical field [0001] The invention relates to a house frame structure in the field of civil building structures, in particular to a frame composed of internal prestressed composite beams and a construction method thereof. 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 is formed by pou...
