Description

Technical Field

[0001] This invention relates to the field of reinforced concrete technology, and in particular to a reinforced concrete structure based on spiral circular reinforcement. Background Technology

[0002] Currently, precast or cast-in-place reinforced concrete is widely used. In reinforced concrete components and structures, the reinforcing steel bars rely on the adhesive force of the concrete to function. The load-bearing reinforcing steel bars are arranged near the surface of the reinforced concrete, with rectangular stirrups added, or multiple layers of mesh reinforcement are arranged, followed by straight tie rods.

[0003] Existing reinforced concrete structures have the following problems: the bond between the steel bars and the concrete is loose and the mutual restraint is poor. When affected by load, external impact, temperature difference deformation, etc., the concrete is prone to cracking and loosening, which radiates and spreads to the outside, damaging the surface concrete and making the steel bars easy to detach from the concrete.

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, 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. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0021] The present invention will be further described below with reference to the accompanying drawings: This invention provides a reinforced concrete structure based on spiral circular structural bars, comprising several load-bearing units. Each load-bearing unit includes several spiral circular structural bars 1, and each spiral circular structural bar 1 is equipped with several main load-bearing bars 2 and several auxiliary bars 3. Each main load-bearing bar 2 is located on the inner edge of the corresponding spiral circular structural bar 1, and the auxiliary bars 3 are located at positions different from the main load-bearing bars 2. Adjacent spiral circular structural bars 1 are interconnected or indirectly connected through several auxiliary bars 3. It can be understood that after assembling several load-bearing units, the reinforced concrete structure can be obtained by pouring concrete 4.

[0022] This invention forms a steel reinforcement skeleton by means of spiral circular structural reinforcement 1, main load-bearing reinforcement 2, auxiliary reinforcement 3, etc., which wraps around concrete 4 like a steel cylinder. Through the constraint performance between different steel bars and the solid bonding force of concrete, the steel bars and concrete 4 are integrated into one, forming a strong and reliable load-bearing unit. By combining and connecting several load-bearing units, various reinforced concrete structures that are strong and unbreakable as a whole can be formed.

[0023] Furthermore, by varying the parameters and combinations of the spiral circular structural reinforcement 1, the main load-bearing reinforcement 2, and the auxiliary reinforcement 3, different types of load-bearing units can be obtained, thereby enabling the construction of various reinforced concrete components. Additionally, in some embodiments, the spiral circular structural reinforcement 1 can be replaced by axially arranged circular stirrups; and other types of reinforcing bars such as the spiral circular structural reinforcement 1, the main load-bearing reinforcement 2, and the auxiliary reinforcement 3 can also be replaced by other novel high-tensile-strength materials.

[0024] Reference Figure 1 As shown, a stress-bearing unit in the first embodiment is illustrated. The stress-bearing unit is a strip structure. The corresponding reinforced concrete structure may include a single stress-bearing unit or multiple stress-bearing units assembled end to end to form strip-shaped reinforced concrete beams, columns, piers, and other structures.

[0025] In this type of load-bearing unit, the diameter of each spiral circle of the spiral circular structural reinforcement 1 is the same, and the center line of the spiral circular structural reinforcement 1 is a straight line; the main load-bearing reinforcement 2 is a straight reinforcement, and the center line of the main load-bearing reinforcement 2 is parallel to the center line of the corresponding spiral circular structural reinforcement 1.

[0026] In this embodiment, the auxiliary reinforcement 3 includes a first auxiliary reinforcement 31 and a second auxiliary reinforcement 32; the first auxiliary reinforcement 31 is a rectangular stirrup integrally disposed on the outside of the spiral circular structural reinforcement 1; the second auxiliary reinforcement 32 is a straight reinforcement, preferably located at the four corners of the first auxiliary reinforcement 31.

[0027] By setting this load-bearing unit in strip-shaped beams, columns and other structures, the spiral circular structural reinforcement 1 and the first auxiliary reinforcement 31 wrap the main load-bearing reinforcement 2 and the concrete 4. Due to the restraining effect of the spiral circular structural reinforcement 1 and the first auxiliary reinforcement 31, it is beneficial to improve the compressive strength, seismic resistance, damage resistance and fatigue resistance of strip-shaped reinforced concrete beams, columns, bridge piers and other structures.

[0028] Further reference Figure 2 As shown, the load-bearing unit may also include pre-cast concrete 4 to fix the spiral circular structural reinforcement 1, the main load-bearing reinforcement 2 and the auxiliary reinforcement 3 into one unit. Subsequently, the different load-bearing units are cast and fixed into one unit by post-cast concrete 4.

[0029] Reference Figures 3-5 As shown, a force-bearing unit in the second embodiment is illustrated. This force-bearing unit is a planar structure. Figure 3 and Figure 4 The image shows force-bearing elements from different perspectives. Figure 5 This shows a load-bearing element containing pre-cast concrete 4.

[0030] Reinforced concrete structures may include a single load-bearing unit or multiple load-bearing units assembled in a plane to form planar structures such as walls and slabs. Additionally, it is understood that for strip structures such as beams and columns, if their width is large enough that a single spiral circular reinforcement bar 1 is difficult to cover, a planar load-bearing unit as described in this embodiment can also be used.

[0031] In this embodiment, multiple spiral circular structural ribs 1 are arranged in one direction, the center lines of the multiple spiral circular structural ribs 1 are parallel to each other, and the multiple spiral circular structural ribs 1 are arranged sequentially along a single direction; the auxiliary ribs 3 are straight ribs, each auxiliary rib 3 is located inside the main load-bearing rib 2, and is set along the arrangement direction of the multiple spiral circular structural ribs.

[0032] In addition, such as Figure 4 As shown, each spiral circular structural rib 1 may not be circular, but rather elliptical as illustrated. Elliptical spiral circular structural ribs 1 are suitable for thinner structures. In actual production, the circular spiral circular structural ribs 1 can be linked together first, and then stretched laterally to the required elliptical cross section.

[0033] Reference Figure 6 As shown, a force-bearing unit in the third embodiment is illustrated. This force-bearing unit is also a planar structure, but it differs from the second embodiment in that multiple spiral circular structural ribs 1 are arranged in both directions.

[0034] Specifically, the center lines of some spiral circular structural reinforcements 1 are parallel to each other and are all set in the longitudinal direction, while the center lines of the remaining spiral circular structural reinforcements 1 are parallel to each other and are all set in the transverse direction. The longitudinal and transverse spiral circular structural reinforcements 1 are arranged alternately. The auxiliary reinforcements 3 are straight reinforcements. Each auxiliary reinforcement 3 is located inside the main load-bearing reinforcement 2, and the auxiliary reinforcements 3 and the main load-bearing reinforcement 2 are arranged alternately.

[0035] The load-bearing units in the second and third embodiments described above can be used in planar reinforced concrete walls, slabs and other structures. Due to the restraining effect of the spiral circular structural reinforcement 1, the main load-bearing reinforcement 2 and the auxiliary reinforcement 3, it is beneficial to improve the compressive strength, shear strength, seismic strength, damage resistance and fatigue resistance of the wall and slab structure. It is suitable for walls, slabs, foundation rafts and road surfaces of houses and high-rise buildings.

[0036] Reference Figure 7 As shown, a load-bearing unit in the fourth embodiment is illustrated. This load-bearing unit is a three-dimensional structure. The reinforced concrete structure includes one load-bearing unit or multiple load-bearing units assembled in a three-dimensional space. This load-bearing unit is mainly used for large-volume reinforced concrete components. Additionally, it can be understood that for planar structures such as walls and slabs, if their thickness is large, making it difficult for a single layer of spiral circular reinforcing bars 1 to cover them, the three-dimensional load-bearing unit of this embodiment can also be used.

[0037] In each load-bearing unit, the centerlines of multiple spiral circular structural reinforcements 1 are parallel to each other, and the multiple spiral circular structural reinforcements 1 are arranged in multiple directions; the auxiliary reinforcements 3 are rectangular stirrups, and each auxiliary reinforcement 3 is located inside the outermost main load-bearing reinforcement 2.

[0038] Due to the restraining effect of the spiral circular structural reinforcement 1, the main load-bearing reinforcement 2 and the auxiliary reinforcement 3, it is beneficial to improve the compressive strength, shear strength, seismic strength, damage resistance and fatigue resistance of large-volume reinforced concrete components; it is suitable for large-volume reinforced concrete structures such as retaining walls, bridge piers, wharves, power station dams, and water conservancy dams.

[0039] Reference Figure 8 and Figure 9 As shown, a force-bearing unit in the fifth embodiment is a first annular column structure.

[0040] In this embodiment, the diameter of each spiral circle of the spiral circular structural reinforcement 1 is the same. The center line of the spiral circular structural reinforcement 1 and the main load-bearing reinforcement 2 are both straight lines. The center lines of multiple spiral circular structural reinforcement 1 are parallel to each other, and the multiple spiral circular structural reinforcement 1 are arranged in a circular ring. The direction of the center line is the height direction of the first annular column structure. The main load-bearing reinforcement 2 is provided at least at the inner end and the outer end of each spiral circular structural reinforcement 1, and is referred to as the inner main load-bearing reinforcement 21 and the outer main load-bearing reinforcement 22, respectively. The auxiliary reinforcement 3 includes the inner auxiliary reinforcement 33 and the outer auxiliary reinforcement 34. The inner auxiliary reinforcement 33 and the outer auxiliary reinforcement 34 are both circular stirrups, and their diameters are different. Each inner auxiliary reinforcement 33 is located outside all the inner main load-bearing reinforcement 21, and each outer auxiliary reinforcement 34 is located inside all the outer main load-bearing reinforcement 22.

[0041] Reference Figure 10 and Figure 11 As shown, a force-bearing unit in a sixth embodiment is illustrated, which is a second annular column structure different from the first annular column structure.

[0042] In this embodiment, the diameter of each spiral circle of the spiral circular structural rib 1 is the same, and the spiral circular structural ribs 1 are connected end to end. The center line of the spiral circular structural rib 1 and the main load-bearing rib 2 are both circular. The size of the circles corresponding to the center lines of multiple spiral circular structural ribs 1 is the same, and multiple spiral circular structural ribs 1 are arranged along the height direction of the second annular column structure. The main load-bearing rib 2 is provided at least at the inner end and the outer end of each spiral circular structural rib 1, and is referred to as the inner main load-bearing rib 21 and the outer main load-bearing rib 22, respectively. The auxiliary ribs 3 are straight ribs. Some of the auxiliary ribs 3 are located inside each outer main load-bearing rib 22, and the rest of the auxiliary ribs 3 are located outside each inner main load-bearing rib 21.

[0043] Both the first and second annular column structures described above can be combined with pre-cast concrete 4 to form annular columnar structures. The first annular column structure is preferably used in reinforced concrete piles, poles, hollow columns, hollow bridge piers, etc.; the second annular column structure is preferably used in reinforced concrete tunnels, culverts, etc. Through special structural design, it is beneficial to improve compressive strength, shear strength, seismic resistance, damage resistance, and fatigue resistance.

[0044] Reference Figure 12As shown, a force-bearing unit in the seventh embodiment is illustrated. This force-bearing unit is an arched shell structure, comprising multiple spiral circular structural ribs 1. Each spiral circular structural rib 1 has the same diameter, and the spiral circular structural ribs 1 are connected end to end. The centerline of the spiral circular structural rib 1 and the main force-bearing rib 2 are both circular. The circular dimensions corresponding to the centerlines of the multiple spiral circular structural ribs 1 are different. The multiple spiral circular structural ribs 1 are arranged in a nested manner, and the height of the spiral circular structural ribs 1 decreases sequentially from the inside to the outside. The main force-bearing ribs 2 are provided at least at the upper and lower ends of each spiral circular structural rib 1, respectively referred to as the upper main force-bearing rib 23 and the lower main force-bearing rib 24. Each auxiliary rib 3 is an arc-shaped rib, and each extends from the center of the arched shell structure to the outer end. The auxiliary ribs 3 include upper auxiliary ribs 35 and lower auxiliary ribs 36. Each upper auxiliary rib 35 is located below all the upper main force-bearing ribs 23, and each lower auxiliary rib 36 is located above all the lower main force-bearing ribs 24.

[0045] With this structure, the arch shell structure can be made as thin as possible by combining the constraint and cohesion performance of the spiral circular structural reinforcement 1 with the main load-bearing reinforcement 2 and auxiliary reinforcement 3, thereby reducing its self-weight and improving the arch shell structure's resistance to compression, shear, earthquake, damage, and fatigue.

[0046] In addition, the reinforced concrete structure can be a composite structure, which is composed of multiple load-bearing units of different types. For example, a composite structure can be a hollow structure, a bridge structure, or a pier structure.

[0047] Reference Figure 13 As shown, in the eighth embodiment, a hollow structure composed of multiple load-bearing units of the aforementioned planar structure is illustrated. The hollow region 7 can be formed into stripes, grids, or squares as needed. The hollow structure exhibits a tube-tube effect, which enhances anti-interference capabilities and reduces self-weight. The hollow region 7 can also be filled with special materials, such as thermal insulation and / or sound insulation materials, as needed. This type of hollow structure is suitable for components such as walls, slabs, columns, beams, bridges, culverts, foundation rafts, and urban corridors. It can also be used for wall panel assembly structural components to reduce self-weight and optimize the overall structural stress distribution of buildings. By filling with thermal insulation and / or sound insulation materials, the desired effects can be achieved, saving energy.

[0048] Reference Figure 14 As shown, in the ninth embodiment, a different hollow structure from the seventh embodiment is presented. This hollow structure consists of a load-bearing unit of the aforementioned planar structure and a load-bearing unit of the aforementioned arched shell structure. Its top can be a thin flat plate, which, together with the thin arched shell at the bottom, forms several hollow regions 7. The hollow regions 7 can also be filled with heat-insulating and / or sound-insulating materials to form a heat-insulating and sound-insulating hollow arched shell panel. Due to the load-bearing characteristics of the hollow arched shell panel, it is particularly suitable for structures such as long-span bridges, houses, and clubhouses.

[0049] Reference Figure 15 and Figure 16 As shown in the tenth embodiment, a bridge structure is illustrated. The bridge deck employs planar structural load-bearing units; in the region at the bottom of the bridge deck, each load-bearing unit is provided with multiple prestressed steel strands 8, and each prestressed steel strand 8 is fitted with a spiral circular structural reinforcement 1 on its outer side, with the prestressed steel strand 8 positioned close to the centerline of the corresponding spiral structural reinforcement 1.

[0050] By using the spiral circular structural reinforcement 1 along the prestressed steel strand 8 and the corresponding main load-bearing reinforcement 2 and auxiliary reinforcement 3, it is beneficial to make the prestressed steel strand 8 and the grouting concrete in contact with it more firmly and reliably bonded, and prevent the expansion damage to the concrete 4 caused by the expansion and contraction of the prestressed steel strand 8; thereby improving the strength of the bridge structure and its shear resistance, seismic resistance, damage resistance and fatigue resistance.

[0051] Reference Figure 17 As shown, in the eleventh embodiment, a support structure is illustrated. It includes a base, the load-bearing unit of which is a single variable-diameter spiral circular structural rib 1. The diameter of the spiral circular structural rib 1 varies uniformly from one end to the other, with the end containing the spiral circle with the largest diameter as the bottom end. The corresponding main load-bearing ribs 2 are straight ribs, each inclined along the inner edge of the variable-diameter spiral circular structural rib 1. The corresponding auxiliary ribs 3 are also straight ribs, each extending from the center of the spiral circle at the bottom end to the edge, and bending upwards at the edge. The load-bearing units above the base are arranged according to the desired shape; in the illustrated embodiment, they are strip-shaped load-bearing units.

[0052] Through this structural design, the constraint performance of the combination of spiral circle 1 and auxiliary reinforcement 01 is beneficial to improving the compressive strength, shear strength, seismic strength, damage resistance, and fatigue resistance of the pier structure; it is suitable for independent piers, multi-pile piers, precast independent piers, etc.

[0053] Reference Figure 18 and Figure 19 As shown, in the twelfth embodiment, a load-bearing unit is illustrated as a connecting joint 6 or a post-cast strip structure. It includes a first load-bearing unit 11 and a second load-bearing unit 12. For the first load-bearing unit 11, the spiral circular structural reinforcement 1, the main load-bearing reinforcement 2, and / or the auxiliary reinforcement 3 include portions reserved outside the pre-cast concrete 4, referred to as reserved portions 5. Reserved portions 5 can serve as anchorage areas for the connecting joint 6 or the post-cast strip structure. Furthermore, a second load-bearing unit 12 can be provided in the reserved portions 5 to connect two adjacent first load-bearing units 11, and the two adjacent first load-bearing units 11 are cast and fixed together as a single unit through the reserved portions 5, the second load-bearing unit 12, and the post-cast concrete 4.

[0054] It is understood that in this embodiment, the first load-bearing unit 11 can be a surface structure, and the second load-bearing unit 12 can be a strip structure; that is, the strip structure load-bearing unit can be used at the connection joint 6 of two surface structure load-bearing units. In other embodiments, other types of connection joints 6 or post-cast strip structures can also be applied. The width of the connection joint 6, the reserved part 5, and the intermediate load-bearing unit structure can be adjusted as needed; connection joints 6 in the transverse, longitudinal, and other directions are all possible. Due to the fusion constraint of the spiral circular structural reinforcement 1 plus auxiliary reinforcement 3 and the reserved part 5, combined with the solidification and bonding effect of the post-cast concrete 4, the reserved part 5 in the connection joint 6 can be welded without welding, and the connection is firm, reliable, and safe; it is suitable for the connection of prefabricated assembly of houses, high-rise buildings, and super high-rise buildings, post-cast strips, etc.

[0055] It is understood that the above description only describes some embodiments of the present invention. Depending on actual needs, by changing the structure and combination of the force-bearing unit, the present invention can also be widely used in other scenarios.

[0056] In summary, the reinforced concrete structure based on spiral circular reinforcing bars provided by this invention forms a reinforcing steel skeleton through spiral circular reinforcing bars 1, main load-bearing bars 2, and auxiliary bars 3, which encloses the concrete 4 like a steel cylinder. The constraint properties between different reinforcing bars, combined with the solid-state bonding force of the concrete, allow the reinforcing bars and concrete 4 to fuse together, forming a robust and reliable load-bearing unit. By combining and connecting several load-bearing units, various robust and unbreakable reinforced concrete structures can be constructed. The constraint properties between different reinforcing bars help reduce the risk of concrete damage and cracking caused by local temperature differences, expansion stress, and external impact pressure, thereby improving the compressive strength, seismic resistance, damage resistance, and fatigue resistance of the reinforced concrete structure. This also helps improve the utilization efficiency of reinforced concrete structures, saves limited steel and concrete resources, promotes green and environmentally friendly construction, and expands the application scope of reinforced concrete structures.

[0057] Finally, it should be noted that the above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
