Non-welding fabricated steel pipe concrete beam-column joint and its construction method

Abstract

The invention relates to a solderless assembly type steel pipe concrete beam column node, which comprises a steel pipe concrete column, wherein an annular sleeve is arranged outside the steel pipe concrete column; a plurality of reinforced concrete beams are annularly arranged at the circumferential side of the annular sleeve. The invention also relates to a construction method of the solderless assembly type steel pipe concrete beam column node. The solderless assembly type steel pipe concrete beam column node and the construction method have the advantages that the structure design is simple, compact and reasonable; all mechanical properties of the node are met; the structure assembly is realized; the assembling speed of components is accelerated; the requirements and the characteristics of an assembly type system are fully met.

Description

Technical field [0001] The invention relates to a non-welded assembled steel tube concrete beam-column node and a construction method thereof. Background technique [0002] At present, as a new type of construction technology, prefabricated building is gradually recognized by people for its convenient production, safety, reliability, and cost-saving characteristics. However, in the connection between reinforced concrete beams and concrete-filled steel tube columns, the steel column cannot be In construction work, the current method of connecting beams and columns is mainly welding. The construction procedure is complicated, it is not easy to achieve rigid connection, and the welding takes a long time, which restricts the construction speed of the entire structure. In addition, a large number of welding is prone to relatively Large residual stress affects the mechanical performance of the node.

Problems solved by technology

[0002] At present, prefabricated buildings, as a new type of construction technology, are gradually recognized by people for their convenient manufacture, safety and reliability, and cost-saving features. In construction work, the current method of connecting beams and columns is mainly based on welding. The construction procedure is complicated, it is not easy to achieve rigid connection, and the welding takes a long time, which restricts the construction speed of the entire structure. In addition, a large number of welding is easy to produce Large residual stress affects the mechanical performance of the joint

[0003] In addition, the current prefabricated buildings shorten the working hours through factory prefabricated components and on-site assembly. However, the construction of beam-column joints is still time-consuming and labor-intensive. The reliability of on-site steel bar binding is affected by the technical proficiency of workers. Insufficiency may lead to unstable quality of node reinforcement binding, which is not suitable for prefabricated structures
