Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a prefabricated assembled beam-column node connection structure. Background Art

[0002] Prefabricated concrete structures, whose components are prefabricated in factories and assembled and connected on-site using specialized joint structures, are increasingly favored by engineers due to their industrialized production and prefabricated construction. They are widely used and rapidly developing worldwide. Beam-column joints are a crucial component of reinforced concrete frame structures. They include the core area where the beams and columns intersect, as well as the connected beam and column ends. Accurate assembly and strengthening of beam-column joints are crucial for prefabricated concrete structures.

[0003] According to application number 201822029233.0, a prefabricated assembled frame beam-column node connection structure includes a cast-in-place frame column and a prefabricated beam. The cast-in-place frame column includes a lower column body. One end where the prefabricated beam and the cast-in-place frame column are assembled is provided with a reserved groove facing the node. A positioning structure is provided at the node between the cast-in-place frame column and the prefabricated beam. The positioning structure includes a positioning column and a positioning hole. A vertical positioning column is provided on the side of the upper end of the lower column body close to the prefabricated beam. One end where the prefabricated beam and the cast-in-place frame column are assembled is provided with a positioning hole corresponding to the positioning column.

[0004] After the lower column of the cast-in-place frame column of this device is cast on site, main reinforcement and positioning columns are left at the upper end. When the precast beam is assembled to the upper end of the lower column, the positioning holes at the assembly end cooperate with the positioning columns to position the precast beam, which helps improve the accuracy of the precast beam assembly and enhance the assembly quality. However, the cast-in-place frame column, lower column, and upper column in this device are fixed together by positioning plates, limit plates, and reinforcing ribs. There is no connection between the cast-in-place frame column, lower column, and upper column, making this connection unstable. Utility Model Content
