AI Technical Summary
During construction, due to the conflict between the curved anchor design at the connection between the top frame beam and the column, the reinforcement bars are difficult to place, the casting quality is difficult to ensure, and the common curved anchor length does not meet the specification requirements, which poses a project safety hazard.
A reinforced concrete top layer edge node connection structure is adopted, including side columns, frame beams and connecting plates. Through the tight fit between the first curved anchor section and the connecting plate, the number of curved anchor sections of the edge column longitudinal ribs is reduced, and the terminal anchoring is used. The plate increases the anchor length, combined with perforated plug welding and double-sided corner welding connections to ensure force transfer reliability.
The indirect connection between the first beam top longitudinal bar and the first side column longitudinal bar is achieved, reducing the number of steel bars at the nodes, ensuring the quality of concrete pouring, facilitating construction, and enhancing the tensile bearing capacity and structural safety of the nodes.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a reinforced concrete top floor edge node connection structure. Background Art
[0002] In civil engineering structures, connecting the top reinforced concrete columns with reinforced concrete beams is a common connection method. Its connection structure is relatively complex and there are a large number of steel bars at the nodes.
[0003] In the relevant existing technologies, the current specifications and atlases have specific provisions for the steel bar connection of the top-level edge nodes of reinforced concrete; for example, the atlas "Drawing Rules and Structural Details for Overall Representation of Plane Planes of Concrete Structure Construction Drawings" 22G101-1, pages 2-14 and 2-15, give the longitudinal reinforcement connection method of the top-level frame column edge nodes.
[0004] However, in actual projects, since there are many longitudinal bars at the column ends of the top frame beams, if the anchoring is performed according to the atlas, the longitudinal bars at the top of the beams conflict with the bending section positioning of each longitudinal bar of the first side column longitudinal bar group, making it difficult to place the steel bars, and the pouring quality of the node concrete is difficult to ensure. In addition, in order to facilitate construction, the following situations generally occur at the construction site: 1. The bending and anchoring length of the column longitudinal bars does not meet the requirements of the specification; 2. The construction workers directly cut off the longitudinal steel bars of the column without setting the bending and anchoring section; 3. The bending and anchoring length of the longitudinal bars of the top plate of the beam is not enough in the column. This will leave hidden safety hazards in the project. Utility Model Content
