[0002] The assembled hybrid frame system consists of beam-column + steel connection nodes. The beam-column connection and column-column connection are achieved by pre-embedding steel connectors at the ends of beams and columns and connecting the steel connectors on site.

[0003] In the prior art, for example, the Chinese patent number CN210713255U is a prefabricated prestressed composite beam-column node for buildings, which uses a traditional reinforced concrete core tube and an outer frame composed of a prefabricated prestressed composite beam-column node and a composite column to form a new type of prefabricated composite beam-column node frame core tube structure system. The key to this structural system is the composite beam-column node, which includes prefabricated reinforced concrete prestressed beam concrete, prefabricated reinforced concrete prestressed beam bottom longitudinal reinforcement, prefabricated reinforced concrete prestressed beam stirrups, prestressed tendons and bolts. The utility model cooperates with prefabricated reinforced concrete prestressed beams and composite columns, and the prefabricated reinforced concrete prestressed beams and composite column node area steel components in the node can all be prefabricated and assembled in the factory, and can be hoisted on site, reducing the workload on site, and the prestressed tendons are tensioned on site, and the post-cast concrete layer on the top of the beam and the post-cast composite column outer concrete are cast on site, which enhances the integrity of the structure, combines the factory with the site, meets the structural safety, and shortens the construction period.

[0004] However, in the prior art, although the above patent has the above technical advantages, it has the disadvantage that when traditional beams and columns are matched with nodes, workers need to use a crane to lift the beams and then match them with the nodes. The volume and weight of the beams and columns and the nodes are very large. When the workers control the movement of the beams and columns by the crane, the beams and columns are prone to shaking and are not easy to match directly with the nodes, which leads to the problem that the workers need to make continuous adjustments and the assembly time is too long.

[0010] Preferably, the inner wall of the main section is fixedly connected with the vertical steel bars through matching holes, and the matching holes are opened in the wall of the main section. A steel bar column is arranged outside the vertical steel bars, and the bottom end of the steel bar column is fixedly connected to the inner wall of the main section.

When assembling the crossbeam, the staff uses a crane to move the crossbeam column to the outside of the side installation shell, and makes one end of the crossbeam column that is stuck in the matching groove fit with the two sides of the L-shaped plate, so as to facilitate the crossbeam column to fully match with the node and speed up the assembly speed. When one end of the crossbeam column is stuck in the matching groove and the insertion hole for installing the steel bar, the thrust of the crossbeam column on the protrusion and the friction between the crossbeam column and the L-shaped plate will drive the L-shaped plate to move into the matching groove until the protrusion is stuck in the main node block.

When one end of the crossbeam column is inserted into the matching groove 4 and the insertion hole 6 of the installation steel bar 5, the thrust of the crossbeam column on the protrusion 8 and the friction between the crossbeam column and the L-shaped plate 7 will drive the L-shaped plate 7 to move into the matching groove 4 until the protrusion 8 is inserted into the main section block 1. At this time, the crossbeam column is fully matched with the node.

[0030] The inner wall of the main section 1 is fixedly connected with the vertical steel bar 12 through the matching hole 11, and the matching hole 11 is opened in the wall of the main section 1. The outside of the vertical steel bar 12 is provided with a steel bar column 13, and the bottom end of the steel bar column 13 is fixedly connected to the inner wall of the main section 1. The node is installed on the top of the vertical beam column.
