Novel assembly type reinforcing steel bar concrete column and steel beam connecting joints

Abstract

The invention discloses novel assembly type reinforcing steel bar concrete column and steel beam connecting joints, and relates to the field of construction steel structure, civil construction technology and mechanical assembly. An end plate with reserved bolt holes is welded on the end part of a steel beam and the end plate is connected with a joint part where a pre-embedded high strength penetrating bolt is connected with the steel pipeline reinforced concrete column through high-strength bolts. According to the novel assembly type reinforcing steel bar concrete column and the steel beam connecting joints, bolt assembly is adopted, prefabricating and welding work is completed in a factory, and the quality is reliable; the anti-seismic performance is excellent, ductility and energy consumption capacity of the joints can be improved significantly; and plastic hinges are moved outward to avoid appearing at the beam end; and repairing or replacing after an earthquake is convenient.

Description

technical field [0001] The invention relates to the fields of building steel structure, civil construction technology and mechanical assembly, in particular to a novel assembled reinforced concrete column and steel beam connection node. Background technique [0002] The development of prefabricated buildings is one of the key points of construction industry reform in recent years. The frame structure system assembled with reinforced concrete columns and steel beams is gradually being applied and developed in engineering practice. The characteristics of its connecting nodes will directly affect the entire structure. Construction performance, performance under normal conditions, safety performance under extreme conditions, and economic indicators of the building in its entire life cycle. Relevant scholars now generally believe that the end-plate connection is a semi-rigid connection. In view of the lack of relevant theories, imperfect joint design and complicated on-site opera...

Problems solved by technology

Relevant scholars now generally believe that the end-plate connection is a semi-rigid connection. In view of the lack of relevant theories, imperfect joint design and complicated on-site operation, there is an urgent need for a kind of anti-seismic performance, convenient and reliable construction, no welding on site, and rapid post-earthquake Replacement and repair, a new type of node that meets the requirements of building industrialization
