Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering, in particular to a sliding connection node between a steel beam and a concrete beam with multiple guarantees. Background Art
[0002] Steel structures are composed of steel materials and are one of the main types of building structures. They primarily consist of components such as steel beams, steel columns, and steel trusses made from sections and steel plates. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. In construction projects such as floor additions, renovations, and reinforcement, it is often necessary to connect steel structural components to reinforced concrete columns. Traditionally, this is done by implanting chemical anchor bolts or anchor bars in the original reinforced concrete columns and then welding them to steel plates to form post-installed steel embedded components. The newly added steel beams are then connected to the embedded components using connecting steel plates.
[0003] According to the application number CN201720639923.0, a connection node between a newly added steel beam and an original concrete beam is proposed; it solves the problems in the prior art that the newly added steel beam and the original concrete beam are prone to slippage and the force on the connection node does not meet the engineering requirements; it includes: a concrete beam, an H-shaped steel beam, a fastening sleeve is fixed on the concrete beam by a chemical anchor bolt, and the fastening sleeve is provided with evenly distributed card grooves, and the card grooves and the card teeth provided on the connecting piece cooperate with each other to prevent the connecting piece and the H-shaped steel beam installed thereon from lateral displacement, and ribs are welded on the H-shaped steel beam at the connecting end of the H-shaped steel beam and the connecting piece, and the steel bars are tightened with double nuts after passing through the ribs. This application only uses steel bars and double nuts for connection, and its connection structure is relatively simple, without multiple connection limits. For this reason, we propose a sliding connection node between a steel beam and a concrete beam with multiple guarantees. Utility Model Content

[0012] 1.
