Description

Technical Field

[0001] This utility model relates to the field of steel bar connection structure technology, and in particular to a steel bar node connection structure that improves corrosion resistance and durability. Background Technology

[0002] In the current method, structural strength is achieved by adding diagonal ribs to the main frame nodes. In fact, the purpose of adding diagonal ribs is to provide strength nodes for the transverse and longitudinal reinforcement. The nodes bear the axial force, bending moment and shear force transmitted from the beam end and column end. In the prior art, Chinese invention patent application, publication number CN119041566A, invention patent application title "Steel Structure Reinforcement Node Device for Multi-Rib Building Structure", the diagonal ribs and the original beams and columns form at least six directions of reinforcement intersection, which solves the problem of the main reinforcement and stirrups being very dense and difficult to arrange and connect during construction. The box-type structure itself is made of thick plates and welded together, with sleeve threaded connections to the reinforcing bars, which fully guarantees strength and connection quality. The technical solution considers the location of the main nodes. However, in actual application, the number and spacing of such main nodes are not very large. Most of the placement is based on the structural arrangement of the building design. A large number of horizontal and vertical reinforcing bars are still constructed by binding to ensure the overall shape. For the treatment of horizontal and vertical reinforcing bars, the strength of the treatment must be guaranteed (due to the long construction time and few main nodes). It is necessary to ensure the strength of most node locations to facilitate long-term construction. In addition, the corrosion resistance and durability of the reinforcing bar node connections are the key to ensuring structural safety and long-term service. The existing corrosion protection method is coating protection. The node connection should avoid the accumulation of moisture in the gaps and should use the same corrosion protection scheme as the main structure. Epoxy coating of reinforcing bars is a commonly used corrosion protection method. However, if the node locations are dense, the spraying will be blocked. That is, the problem with the existing technology is that there is no connection structure that can guarantee strength to improve durability while minimizing the impact of dense nodes on anti-corrosion spraying. Utility Model Content

[0003] This invention aims to address the technical problem of the lack of a connection structure in the prior art that can ensure strength to improve durability while minimizing the impact of dense nodes during anti-corrosion spraying, and provides a steel bar node connection structure that improves both anti-corrosion performance and durability.

[0004] To solve the above-mentioned technical problems, the specific technical solution of this utility model is as follows: A reinforced concrete joint connection structure for improving corrosion resistance and durability, comprising: The interlacing of transverse and longitudinal reinforcing bars forms node locations; A transverse reinforcing bar limiting component, which enables the transverse reinforcing bar to be engaged in the transverse limiting space it forms; The longitudinal reinforcement limiting component enables the longitudinal reinforcement to be engaged in the longitudinal limiting space it forms. The transverse reinforcing bar limiting component and the longitudinal reinforcing bar limiting component have the same structure and both have limiting components and guide connecting rods; The limiting component has multiple sparsely spaced strips to facilitate spraying coverage of the transverse and longitudinal reinforcing bars during anti-corrosion spraying; and A stabilizing block, wherein the guide connecting rod can be inserted into the stabilizing block to ensure that the transverse reinforcing bars and the longitudinal reinforcing bars are radially fitted at the node position.

[0005] Specifically, the limiting component includes: A limiting ring-shaped body with a notch; An arc-shaped deformable piece is formed on the side of the limiting ring body opposite to the notch; The arc-shaped deformable piece bends toward the center of the limiting ring body; The notch has an arc-shaped blocking part.

[0006] Specifically, the diameter of the limiting ring body is larger than the diameter of the transverse reinforcing bar or the longitudinal reinforcing bar.

[0007] Specifically, in the radially fitted state, the limiting component is away from the node position.

[0008] Specifically, the arc-shaped blocking portion bends away from the gap.

[0009] Specifically, the arc-shaped deformable sheet is provided with threaded holes; A connecting screw, one end of which can be inserted into the threaded hole and screwed onto a fixing nut; The other end of the connecting screw is connected to the guide connecting rod.

[0010] Specifically, the stabilizing block has: mutually perpendicular and non-intersecting transverse through holes and longitudinal through holes; A minimum distance is formed between the transverse through hole and the longitudinal through hole; The guide connecting rod can be inserted into and pass through the transverse through hole or the longitudinal through hole.

[0011] Specifically, the guide connecting rod is provided with external threads; The guide connecting rod can be screwed onto a locking nut to lock the guide connecting rod onto the stabilizing block.

[0012] This utility model has the following beneficial effects: This solution does not directly act on the node location. Instead, it uses limiting components at adjacent node locations to radially restrict the transverse and longitudinal reinforcing bars. The actual fixing is achieved through a crisscrossing of transverse and longitudinal reinforcement using guide connecting rods and stabilizing blocks. The limiting components can actually be adjusted and slid on the surface of the reinforcing bars without obstructing the node location. The reinforcing bar body can be sprayed first, and then the node location can be treated in an orderly manner to ensure the anti-corrosion effect. The multiple gaps and sparse strips are more conducive to subsequent observation and maintenance. Attached Figure Description
