The invention relates to a steel pipe concrete frame equipped with prestressed tendons and a construction method thereof. The steel pipe concrete frame equipped with prestressed tendons is composed of composite columns and composite beams connected through joints, and the composite beams are horizontally arranged between the composite columns. It is an outer jacket integral node filled with self-compacting concrete; the composite column is a segmental steel pipe concrete composite column with built-in steel; the composite beam is a prestressed I-shaped steel pipe concrete composite beam in the body; The outer tube of the node is bypassed in the reinforced ring plate with cavity, and the prestressed tendon is positioned through the single-hole positioning plate and the double-hole main positioning plate with holes. The self-compacting fine-grain concrete of the beam and the self-compacting fine-grain concrete of the node end beam are connected, and are integrated with the outer tube of the node after curing. The invention solves the problem that the connection nodes of the beam-column joints of the steel pipe concrete novel frame with prestressed tendons are complex and easy to be damaged.
Description
Technical field [0001] The invention relates to a house frame structure in the field of civil construction structures, in particular to a steel tube concrete frame equipped with prestressed tendons and a construction method thereof. Background technique [0002] In the conventional reinforced concrete frame structure system, most of the frame nodes are cast-in-place reinforced concrete nodes. Like frame beams and columns, this type of reinforced concrete nodes require formwork, lashing of steel bars and then concrete pouring. The components have low bearing capacity and a long construction period. Moreover, the nodes are prone to damage under the action of earthquake. With the rapid development of the civil construction industry, concrete-filled steel tube structures have been widely used in large-span, heavy-duty and ultra-high buildings. The concrete-filled steel tube frame with prestressed tendons is a new structural form of concrete-filled steel tube structures. The steel tu...
