Description

Technical Field

[0001] The utility model relates to the technical field of precast beam columns, in particular to an assembled concrete precast beam column connection node. Background Technique

[0002] In the construction of assembled concrete buildings, the beam-column joint is a very critical joint. It not only affects the stability and safety of the mechanical properties of concrete structures, but also has an obvious impact on improving the economic benefits of construction enterprises. Due to different domestic and foreign specifications, the classification of connection methods is also different. From the construction method, most of them belong to two types: wet connection and dry connection. For wet connection, concrete or cement slurry is poured during connection for anchoring, such as ordinary cast-in-place connection between beams and columns, and integral pouring connection of prestressed technology. For dry connection, concrete is not poured during connection, but steel plates or other steel components are implanted into the connected components, and bolt connection or welding is used to achieve the connection purpose, such as tongue-and-groove connection and corbel connection between beams and columns. The tongue-and-groove connection is a new type of dry connection for assembled frame beam columns. The difference from the ordinary tongue-and-groove connection is that this connection is a dry splicing rigid connection. In the tongue-and-groove connection, the notched beam and the beam corbel are connected by welding a movable connection cover plate to the embedded parts. The precast beam is made into a notched beam, and the forces on the notched beam and the beam end cantilever corbel are equal in magnitude and opposite in direction. So far, there has been little research on the beam rigidity formed by tongue-and-groove connection at home and abroad. Tests show that the local stiffness of the tongue-and-groove connection beam decreases, and the deflection and rotation angle increase, but it has little impact on the overall deformation of the component. Moreover, it is simple and fast in construction, is a relatively economical connection method, and does not affect the beam height of the building.
