Description

Technical Field

[0001] This invention belongs to the field of building structure technology, and in particular relates to a high-strength and high-toughness concrete structure. Background Technology

[0002] With the continuous development of the economy and society, the number of port facilities, wharves, and cross-sea bridges is constantly increasing, and the tonnage and number of ships are also rising in tandem.

[0003] Compared to gravity wharves and sheet pile wharves, high-pile wharves are one of the main structural forms of wharves in my country. Steel-concrete composite (SCPC) piles, as an important component and load-bearing structure of high-pile wharves, significantly improve the bearing capacity of the piles due to the external steel pipes constraining the lateral deformation of the internal concrete. However, SCPC piles have relatively low horizontal bearing capacity and lateral stiffness. When large tonnage ships berth, improper speed control due to high inertia, as well as human error, often leads to excessive horizontal impact forces. Under impact, the SCPC structure deforms due to insufficient energy absorption capacity of the internal concrete, thus affecting the overall toughness of the wharf structure. In severe cases, it can even cause the entire high-pile wharf structure to collapse. Therefore, improving the resistance of SCPC piles to horizontal deformation in high-pile wharves and further enhancing the synergistic effect of SCPC piles has become a key issue in current engineering construction.

[0004] Therefore, there is an urgent need for a high-strength and high-toughness concrete structure. Summary of the Invention

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1 to 2 This invention discloses a high-strength, high-toughness concrete structure, comprising:

[0032] The outer casing is 1, and the interior is filled with concrete;

[0033] Multiple vertical ribs 7 are inserted inside the outer casing 1. The multiple vertical ribs 7 are evenly spaced around the axis of the outer casing 1 and are parallel to the axis of the outer casing 1.

[0034] Multiple sets of longitudinally reinforced structures are fixedly connected to multiple vertical reinforcing bars 7 respectively;

[0035] Multiple sets of transverse reinforcing structures are arranged sequentially at intervals along the length of the outer tube 1, and the transverse reinforcing structures are fixedly connected to the outer tube 1.

[0036] The longitudinal reinforcement structure and the transverse reinforcement structure are fixedly connected.

[0037] The outer casing 1 is preferably made of a material resistant to seawater corrosion.

[0038] In this invention, vertical reinforcing bars 7 are provided inside the outer casing 1, and longitudinal reinforcing structures are provided on the vertical reinforcing bars 7. The longitudinal reinforcing structures increase the tensile and compressive strength of the concrete structure in the vertical direction, and the transverse reinforcing structures increase the impact resistance of the concrete structure in the horizontal direction, thereby increasing the toughness of the concrete structure and enabling the concrete structure to withstand higher stress.

[0039] Further optimization of the plan, including vertical structural reinforcement, includes:

[0040] Multiple first ring bodies 3 are arranged along the length direction of the vertical rib 7, and adjacent first ring bodies 3 are fixedly connected.

[0041] The vertical reinforcement 7 penetrates multiple first ring bodies 3, and the first ring bodies 3 located at both ends are fixed to the vertical reinforcement 7.

[0042] Two adjacent first ring bodies 3 are fixedly connected. When the concrete structure is subjected to tension or compression, the vertical reinforcement 7 and the concrete share the load. At this time, multiple first ring bodies 3 share the tension or compression with the vertical reinforcement 7, increasing the load-bearing capacity of the vertical reinforcement 7 and the concrete. At the same time, micro-deformation occurs between multiple first ring bodies 3, thereby increasing the vertical load-bearing capacity of the concrete structure.

[0043] Further optimization of the plan includes horizontal structural reinforcement, including:

[0044] Multiple third ring bodies 6 are arranged at equal intervals around the axis of the outer tube body 1, and adjacent third ring bodies 6 are fixedly connected. The axis of the third ring body 6 is parallel to the axis of the outer tube body 1.

[0045] An elastic sheet 5 is fixed to the side of the third ring body 6 near the inner wall of the outer tube body 1. The concave surface of the elastic sheet 5 faces the inner wall of the outer tube body 1, and the elastic sheet 5 is located inside the third ring body 6.

[0046] One end of the first connecting rod 2 is fixedly connected to the middle of the concave surface of the elastic sheet 5. The other end of the first connecting rod 2 passes through the third ring body 6 and is fixed to the inner wall of the outer tube body 1. The first connecting rod 2 is perpendicular to the inner wall of the outer tube body 1, and the first connecting rod 2 is slidably connected to the third ring body 6.

[0047] When the side wall of the outer tube 1 is subjected to force, the force is transmitted to the elastic plate 5 through the first connecting rod 2, and then the elastic plate 5 transmits the force to the third ring 6. The force on the outer tube 1 is borne by multiple mechanisms, which increases the concrete structure's ability to withstand horizontal impact forces. At the same time, the third ring 6 and the elastic plate 5 undergo micro-deformation when subjected to force, which increases the horizontal strength of the concrete structure.

[0048] In a further optimized design, the third ring body 6 is set as a hexagonal star shape, and a connecting groove is formed at the outer edge of two adjacent third ring bodies 6. A second ring body 4 is fixedly connected in the connecting groove, and the first ring body 3 is fixedly connected to the second ring body 4.

[0049] The third ring body 6 is set in a hexagonal star shape, which is easy to produce micro-deformation, and works with the elastic sheet 5 to consume the force of horizontal impact on the outer tube body 1.

[0050] With this configuration, the longitudinal and transverse reinforcing structures are connected into a whole under the action of the second ring 4, increasing the overall toughness of the concrete structure and making the entire concrete structure more stable and solid.

[0051] In a further optimized design, both the first ring body 3 and the second ring body 4 are set as regular hexagons. The two side walls of the first ring body 3 and the second ring body 4 are fixedly connected. The axes of the first ring body 3 and the second ring body 4 are set perpendicularly, and the intersection of the axes of the first ring body 3 and the second ring body 4 is located at the center of the first ring body 3 and the second ring body 4.

[0052] Both the first ring body 3 and the second ring body 4 are set as regular hexagons to simulate a honeycomb structure, making the entire structure more stable and robust.

[0053] To further optimize the design, a connecting ring 8 is installed between multiple third ring bodies 6. The connecting ring 8 is fixedly connected to the multiple third ring bodies 6 and is coaxially arranged with the outer casing 1. With the multiple third ring bodies 6 fixedly connected to each other, the connecting ring 8 is installed between the multiple third ring bodies 6 to provide secondary reinforcement, further increasing the stability of the entire structure.

[0054] In this invention, when the outer tube 1 is subjected to tensile force, pressure or horizontal impact force, the outer tube 1 transmits the force to the longitudinal reinforcement structure and the transverse reinforcement structure located inside the outer tube 1. The longitudinal reinforcement structure and the transverse reinforcement structure are integrated and share the force borne by the outer tube 1, thereby improving the toughness of the concrete structure and improving the stress self-adaptation ability of the concrete structure.

[0055] In actual use, multiple vertical reinforcing bars 7 penetrate the top and bottom of the outer tube 1. The transverse and longitudinal reinforcing structures are applied to the parts of the concrete pile subjected to horizontal forces. When the concrete pile is impacted by an external force, the outer tube 1 transmits the force to the first connecting rod 2 on the force-bearing side. The first connecting rod 2 transmits the force to the elastic plate 5. Under the action of the inner force, the elastic plate 5 undergoes elastic deformation, which in turn causes the two adjacent sides of the third ring 6 to deform. The third ring 6 transmits the force to the second ring 4, the second ring 4 transmits the force to the first ring 3, and then to the vertical reinforcing bars 7, thereby dispersing the force to the entire structure, thus making the strength and toughness of the present invention higher.

Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
