Description

Technical Field

[0001] The present application relates to the technical field of reinforced concrete frame reinforcement, and in particular to a HDC wire wrapping reinforcement device for reinforced concrete frame nodes. Background Art

[0002] The patent with the published authorization announcement number CN214885767U discloses a HDC wire-wrapped reinforcement device for reinforced concrete frame nodes, including a vertical frame column and a horizontally extending frame beam on its periphery. The reinforcement area of ​​the reinforcement device includes a full-height replacement area and a partial replacement area that are interconnected. The full-height replacement area is formed by chiseling through the contact end of the frame beam itself and the frame column, and the partial replacement area is formed by chiseling inward from the outer peripheral surface of the frame column to the node core area inside the frame column. The exposed stirrups in the node core area are fixedly connected with vertical steel bars at the midpoints of each leg, and each steel bar is connected into a whole by cold-drawn steel wire. The full-height replacement area and the partial replacement area are both reinforced by HDC spray filling. By setting up multiple replacement areas, the beam end reinforcement is weakened, the number of plastic hinges at the beam end under earthquake action is increased, and the redundancy of node damage is improved. The use of cold-drawn steel wire and wire-wrapped steel bars can more efficiently constrain the concrete in the core area, improve the hoop effect of the core area, and increase the restraint on the concrete.

[0003] The HDC wire-wrapped reinforcement device for reinforced concrete frame nodes in the above-mentioned patent has an insignificant reinforcement effect on the frame beam. Therefore, after long-term use, when the frame beam is subjected to vibration, its stabilization effect gradually becomes unstable, thereby affecting the use effect.
