Abstract
Description
Technical Field
[0001] This utility model relates to the field of building joint technology, specifically to a complex steel reinforcement joint structure for steel-concrete lapped columns. Background Technology
[0002] In modern building structural design, steel-concrete composite (SRC) structures combine the advantages of steel and concrete, possessing high strength, good ductility, and seismic performance. They can effectively resist the effects of natural disasters such as earthquakes and wind loads, improving the safety and service life of buildings. They are widely used in high-rise buildings, bridges, and other structures requiring high strength and good durability.
[0003] However, traditional steel-concrete joint designs have certain shortcomings. First, the reinforcement arrangement is often chaotic. This chaotic arrangement not only increases construction difficulty but also easily leads to errors during construction, affecting the final structural quality. Furthermore, many traditional steel-concrete joint designs fail to adequately consider the impact of torsional stress and lack effective anti-torsional measures. Torsional stress is a complex stress generated in buildings under dynamic loads such as wind loads and earthquakes, and it has a significant impact on the stability and safety of the structure. The lack of effective anti-torsional measures may cause joints to crack, deform, or even fail under torsional stress, affecting the overall performance and service life of the building.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] In response to the problems in related technologies, this utility model proposes a complex steel reinforcement node structure for steel-concrete lapped columns to overcome the aforementioned technical problems existing in the prior art.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] A complex steel-concrete lap joint column structure includes longitudinal steel sections, two first transverse steel sections connected below the longitudinal steel sections, connecting plates fixedly connected to both sides of the first transverse steel sections, a lower longitudinal bar at the bottom of the first transverse steel sections, an anti-torsion bar above the lower longitudinal bar, an upper longitudinal bar above the anti-torsion bar, and a U-shaped hoop at the bottom of the lower longitudinal bar, with a limiting bar fixedly connected to the U-shaped hoop.
[0008] Furthermore, to facilitate the splicing of the first transverse steel and the second transverse steel, a second transverse steel is provided on one side of one of the first transverse steels, and a fixing plate is provided between the first transverse steel and the second transverse steel. One end of the fixing plate is fixedly connected to the first transverse steel, and the other end is provided with a slider. A sliding groove is provided inside the second transverse steel, and the slider matches the sliding groove.
[0009] Furthermore, a positioning groove is provided on one side of the first transverse steel section, and a positioning block is fixedly connected to one side of the second transverse steel section, with the positioning block matching the positioning groove.
[0010] Furthermore, anti-torsional reinforcement is placed inside the connecting plate.
[0011] Furthermore, in order to limit and fix the limiting steel bars, limiting posts are provided on the outer side of the longitudinal steel, and the limiting steel bars are connected to the limiting posts.
[0012] Furthermore, in order to fix multiple U-shaped hoops, rectangular hoops are provided on the outside of the U-shaped hoops.
[0013] Furthermore, extension plates are provided on both sides of the longitudinal steel section.
[0014] The beneficial effects of this utility model are as follows:
[0015] (1) By connecting two first transverse steel sections below the longitudinal steel section and setting the lower longitudinal reinforcement at its bottom end, and setting anti-torsion reinforcement and upper longitudinal reinforcement above the lower longitudinal reinforcement, a strong stress system is formed, which effectively enhances the overall bearing capacity of the node and can effectively optimize the reinforcement layout, avoid the problem of chaotic reinforcement layout in traditional design, and significantly improve the anti-torsion performance of the node by setting anti-torsion reinforcement, ensuring the stability of the structure when subjected to lateral force.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] According to an embodiment of the present invention, a complex steel reinforcement node structure for a steel-concrete lap joint column is provided.
[0026] Example 1
[0027] like Figures 1-4As shown, the complex steel reinforcement node structure of the steel-concrete lap joint column according to the embodiment of this utility model includes a longitudinal steel section 1, two first transverse steel sections 2 connected below the longitudinal steel section 1, connecting plates 3 fixedly connected to both sides of the first transverse steel section 2, a lower longitudinal reinforcement 4 provided at the bottom end of the first transverse steel section 2, an anti-torsion reinforcement 5 provided above the lower longitudinal reinforcement 4, and an upper longitudinal reinforcement 6 provided above the anti-torsion reinforcement 5. The upper longitudinal reinforcement 6 and the lower longitudinal reinforcement 4 bend downward and upward respectively when they come into contact with the longitudinal steel section 1, so as to facilitate their connection with the longitudinal steel section 1. A U-shaped hoop 7 is provided at the bottom end of the lower longitudinal reinforcement 4, and a limiting reinforcement 8 is fixedly connected to the U-shaped hoop 7. The U-shaped hoop 7 is connected to the anti-torsion reinforcement 5. The anti-torsion reinforcement 5 is located inside the connecting plate 3 and is used to block the anti-torsion reinforcement 5. A limiting post 15 is provided on the outside of the longitudinal steel section 1, and the limiting reinforcement 8 is connected to the limiting post 15, so as to limit and fix the limiting reinforcement 8. This limiting and fixing method effectively prevents the limiting steel bar 8 from shifting or falling off during construction, ensuring the overall stability and safety of the structure. Extension plates 17 are provided on both sides of the longitudinal steel bar 1, increasing the contact area of the longitudinal steel bar 1 and improving the overall stability and load-bearing capacity of the structure. A rectangular hoop 16 is provided on the outside of the U-shaped hoop 7 to fix it and prevent it from shifting. Through the above scheme, the lower longitudinal reinforcement 4 is set to bear the vertical load; the upper longitudinal reinforcement 6 works in conjunction with the lower longitudinal reinforcement 4 to optimize the stress distribution of the entire node area; the anti-torsional steel bar 5 is set to resist torsional stress; and the limiting steel bar 8 can separate and fix the multiple upper longitudinal reinforcement 6 and lower longitudinal reinforcement 4. This separated arrangement not only avoids mutual interference between the steel bars but also ensures uniform spacing between them, improving the stress performance and load-bearing capacity of the steel bars. Furthermore, by moving the first row of edge longitudinal reinforcement bars of the lower longitudinal reinforcement 4 to the second row for merging, the steel bar arrangement is effectively optimized, the load-bearing capacity is improved, and concrete pouring is facilitated.
[0028] like Figures 1-4As shown, a second transverse steel section 9 is provided on one side of a first transverse steel section 2. A fixing plate 10 is provided between the first transverse steel section 2 and the second transverse steel section 9. One end of the fixing plate 10 is fixedly connected to the first transverse steel section 2, and the other end is provided with a slider 11. A sliding groove 12 is provided inside the second transverse steel section 9, and the slider 11 matches the sliding groove 12. A positioning groove 13 is provided on one side of the first transverse steel section 2, and a positioning block 14 is fixedly connected to one side of the second transverse steel section 9, and the positioning block 14 matches the positioning groove 13. Through the above scheme, by placing the positioning block 14 inside the positioning groove 13, the first transverse steel section 2 and the second transverse steel section 9 can be accurately positioned. This accurate positioning can effectively avoid errors that occur during the splicing process, ensuring that the spliced structure has good alignment and stability. Furthermore, when the positioning block 14 is inserted into the positioning groove 13, the slider 11 can move inside the sliding groove 12, realizing the splicing between the first transverse steel section 2 and the second transverse steel section 9, which facilitates the subsequent welding of the connection between the first transverse steel section 2 and the second transverse steel section 9.
[0029] In summary, by utilizing the above-mentioned technical solution of this utility model, a strong load-bearing system is formed by connecting two first transverse steel sections 2 below the longitudinal steel section 1, setting a lower longitudinal reinforcement 4 at its bottom end, and setting an anti-torsional steel reinforcement 5 and an upper longitudinal reinforcement 6 above the lower longitudinal reinforcement 4. This effectively enhances the overall load-bearing capacity of the joint and optimizes the reinforcement arrangement, avoiding the problem of chaotic reinforcement arrangement in traditional designs. Furthermore, by setting the anti-torsional steel reinforcement 5, the torsional performance of the joint is significantly improved, ensuring the stability of the structure under lateral forces. Additionally, by setting a fixing plate 10, a slider 11, and a groove 12 between the first transverse steel section 2 and the second transverse steel section 9, the first transverse steel section 2 and the second transverse steel section 9 can be easily spliced. This splicing method is not only simple to operate but also ensures that the spliced structure has good integrity and stability, facilitating the welding of the first transverse steel section 2 and the second transverse steel section 9.
