In some examples, methods, means, elements and circuits that are well known to those skilled in the art are not described in detail, in order to highlight the main idea of the present application.

[0029] The present application provides a reinforcing structure of a cross-span cantilever beam, which is suitable for being installed at the connection between a beam column 120 and a cantilever beam 110, such as Figures 1 to 4As shown, it includes: a first supporting bar 210, a second supporting bar 220, and a reinforcing bar 230; the first supporting bar 210, the second supporting bar 220, and the reinforcing bar 230 are all installed inside the beam-column 120 and the cantilever beam 110; the first supporting bar 210 includes: a first U-shaped seat 211 and two first bends 212, the opening of the first U-shaped seat 211 faces downward, and the two first bends 212 are respectively fixed at both ends of the opening of the first U-shaped seat 211; the reinforcing bar 230 includes: a second U-shaped seat 231, a second bend 232, and a third bend 233; the opening of the second U-shaped seat 231 is connected to the first... The openings of the U-shaped seat 211 are opposite each other. The second bent portion 232 and the third bent portion 233 are respectively fixedly disposed at both ends of the opening of the second U-shaped seat 231. The second U-shaped seat 231 and the first U-shaped seat 211 are arranged intersectingly. The second support rib 220 includes: a third U-shaped seat 221 and two fourth bent portions 222. The opening of the third U-shaped seat 221 is opposite to the opening of the second U-shaped seat 231. The two fourth bent portions 222 are respectively fixedly disposed at both ends of the opening of the third U-shaped seat 221. The third U-shaped seat 221 and the second U-shaped seat 231 are arranged intersectingly, and the third U-shaped seat 221 and the first U-shaped seat 211 are arranged adjacent to each other.

[0030] It should be noted here that, as Figure 1 , Figure 3 As shown, the first support bar 210, the second support bar 220, and the reinforcing bar 230 are all fixedly installed inside the connection between the cantilever beam 110 and the beam-column 120 by casting. The first support bar 210, the second support bar 220, and the reinforcing bar 230 are all used to fix the cantilever beam 110. The first U-shaped seat 211 is fixedly installed inside the beam-column 120 and the cantilever beam 110, and its two ends are respectively anchored into the cantilever beam 110. The first U-shaped seat 211 is used to provide bending support. The first U-shaped seat 211 is fixedly provided with a first bending part 212 at both ends of the cantilever beam 110. The design of the first bending part 212 increases the contact area and anchorage length between the first support bar 210 and the cantilever beam 110, improves the shear strength of the cantilever beam 110, and enhances the stability of the anchorage.

[0031] like Figure 1 , Figure 2As shown, the opening of the second U-shaped seat 231 is arranged opposite to the opening of the first U-shaped seat 211, so that the first support rib 210 cooperates with the reinforcing steel bar 230, not only increasing the anchoring length of the reinforcing steel bar 230 at the end of the cantilever beam 110, but also further improving the shear and bending strength of the cantilever beam 110. The second U-shaped seat 231 is arranged in cross with the first U-shaped seat 211 to form a stable steel framework. When the cantilever beam 110 is subjected to vertical load, horizontal load and other complex forces, the cross reinforcing steel bar 230 and the first support rib 210 can jointly resist shear forces in different directions, improve the bearing capacity of the connection between the cantilever beam 110 and the beam column 120, and enhance the seismic performance of the overall structure.

[0032] As shown in Figure 1 , Figure 4 , the third U-shaped seat is anchored into the cantilever beam 110 at both ends, so that the second support rib 220 is firmly embedded in the cantilever beam 110. The design of the fourth bending part 222 further increases the contact area and anchoring length of the second support rib 220 and the cantilever beam 110, so that the cantilever beam 110 can withstand greater shear strength. The third U-shaped seat is arranged in cross with the second U-shaped seat and adjacent to the first U-shaped seat, so that the first support rib 210, the second support rib 220 and the reinforcing steel bar 230 are closely linked together. When the cantilever beam 110 is subjected to external force, the first support rib 210, the second support rib 220 and the reinforcing steel bar 230 cooperate with each other to resist external force, further enhancing the shear strength and bending strength of the cantilever beam 110 at the connection with the beam column 120.

[0033] Compared with the prior art, the reinforcing steel bar 230, the first support rib 210 and the second support rib 220 are all arranged inside the connection between the cantilever beam 110 and the beam column 120, completely avoiding the occupation of external space, reducing the influence on the layout and use of surrounding facilities, and maximizing the effective use of building space. At the same time, the direct erosion of the reinforcing steel bar 230, the first support rib 210 and the second support rib 220 by the natural environment is avoided, significantly prolonging the service life. The reinforcing steel bar 230, the first support rib 210 and the second support rib 220 work together to resist shear force. When the cantilever beam 110 is subjected to shear force, the reinforcing steel bar 230 can share part of the shear force of the first support rib 210 and the second support rib 220, so that the cantilever beam 110 can better resist shear force, avoiding the occurrence of cracks at the connection between the cantilever beam 110 and the beam column 120 due to excessive shear force, improving the shear resistance of the connection between the cantilever beam 110 and the beam column 120, and ensuring the stability of the overall structure.

[0034] As shown in Figure 1As shown, in order to reduce the deflection and deformation of the cantilever beam end and improve the overall stability of the cantilever beam, the bottom of the cantilever beam is inclined from the fixed position of the beam column to the end of the cantilever beam, wherein one first bending part 212 and a fourth bending part 222 are inclinedly arranged inside the cantilever beam, and the length direction of the first bending part 212 and the length direction of the fourth bending part 222 are arranged in parallel with the length direction of the bottom of the cantilever beam. The inclined design makes the cantilever beam, the first bending part 212 and the fourth bending part 222 work together to better resist external load and vibration, thereby improving the overall stability.

[0035] It should be pointed out here that when 2500>L>1500, only the first supporting rib 210 and the reinforcing rib 230 need to be arranged to ensure the stability of the overall structure, and when 3600>L>2500, the second supporting rib 220 needs to be added on the basis of the first supporting rib 210 and the reinforcing rib 230 to ensure the stability of the overall structure. Wherein, L is the length of the cantilever beam 110 cantilevered out of the beam column 120.

[0036] In one possible implementation manner, as shown in Figure 2 , a first preset angle α is arranged between the length direction of the bottom edge of the second U-shaped seat 231 and the length direction of the two side edges of the second U-shaped seat 231. It should be pointed out here that the design of the first preset angle α makes the anchoring force of the reinforcing rib 230 better match the main stress direction, thereby maximizing the anchoring effect of the reinforcing rib 230.

[0037] Further, the value range of the first preset angle α is 30-60°; preferably, the value of the first preset angle α is 45°.

[0038] In one possible implementation manner, as shown in Figure 1 , Figure 2 , the length direction of the second bending part 232 is parallel to the length direction of the third bending part 233, and the length h3 of the second bending part 232 is greater than the length h4 of the third bending part 233; the longer second bending part 232 can increase the length of the reinforcing rib 230 anchored into the cantilever beam 110, thereby improving the shear and bending strength of the cantilever beam 110 and enhancing the stability of the anchoring.

[0039] Preferably, the value of the length h3 of the second bending part 232 is 800mm, and the value of the length h4 of the third bending part 233 is 300mm.

[0040] Further, the diameter of the reinforcing rib 230 is in the range of 16mm-25mm.

[0041] Further, as shown in Figure 1 , Figure 2As shown, the second bending part 232 and the third bending part 233 are fixedly connected with the second U-shaped seat 231 respectively, and the second bending part 232 and the third bending part 233 extend towards the direction away from the second U-shaped seat 231, and the end of the second bending part 232 and the third bending part 233 away from the second U-shaped seat 231 is provided with a folded edge 234, and the design of the second bending part 232 and the third bending part 233 enhances the mechanical engagement between the cantilever beam 110, when the second bending part 232 and the third bending part 233 are subjected to shear force, the folded edge 234 forms a structure similar to "barb" to prevent the second bending part 232 and the third bending part 233 from being pulled out from the inside of the cantilever beam 110, so that the reinforcing steel bar 230 can withstand a larger shear force, and the stability of the structure is enhanced.

[0042] Further, the second U-shaped seat 231, the second bending part 232, the third bending part 233 and the folded edge 234 are integrally formed by steel bending, the design of integral forming prevents the reinforcing steel bar 230 from separating or failing during the stress process, enhances the integrity and stability of the structure, and ensures the stability of the anchoring of the reinforcing steel bar 230.

[0043] In a possible implementation manner, as shown in Figure 1 , Figure 3 , the first U-shaped seat 211 is provided with a second preset angle β between the top length direction and the side length direction of the first U-shaped seat 211; the second preset angle β enhances the anchoring strength of the first supporting steel bar 210, and improves the shear strength of the cantilever beam 110.

[0044] Further, the value of the second preset angle β is 45°.

[0045] In a possible implementation manner, as shown in Figure 1 , Figure 4 , the third U-shaped seat 221 is provided with a third preset angle γ between the top length direction and the side length direction of the third U-shaped seat 221; the design of the third preset angle γ enhances the anchoring strength of the second supporting steel bar 220, and further improves the shear strength of the cantilever beam 110.

[0046] Further, the second preset angle β and the third preset angle γ are the same; the same angle setting makes the first U-shaped seat and the third U-shaped seat cooperate with each other in the transmission direction of tensile stress and compressive stress, so that the stress can be more effectively transmitted from the cantilever beam 110 to the beam column 120, further improves the bearing capacity of the connection between the beam column 120 and the cantilever beam 110, and ensures the stability of the overall structure.

[0047] Further, as shown in Figure 1 , Figure 3 , Figure 4As shown, the top length h2 of the third U-shaped seat 221 is greater than the top length h1 of the first U-shaped seat 211, and the third U-shaped seat 221 with a longer top can increase the length of the second support rib 220 anchored into the cantilever beam 110, further improve the shear and bending strength of the cantilever beam 110, enhance the stability of anchoring, and ensure the stability of the overall structure.

[0048] In one possible implementation, a locking part (not shown in the figure) is further included; the second U-shaped seat 231 is fixedly connected with the first U-shaped seat 211 and the third U-shaped seat 221 through the locking part.

[0049] It should be noted that the two side edges of the second U-shaped seat 231 are arranged to intersect with the two side edges of the first U-shaped seat 211, one side edge of the second U-shaped seat 231 is arranged to intersect with one side edge of the third U-shaped seat 221, and the second bending part 232 of the second U-shaped seat 231 is arranged to overlap with the top of the third U-shaped seat 221; the fixed connection of the locking part forms a stable overall structure among the first support rib 210, the second support rib 220 and the reinforcing steel bar 230, increases the anchoring length and anchoring force of the first support rib 210, the second support rib 220 and the reinforcing steel bar 230 inside the cantilever beam 110, and when the cantilever beam 110 is stressed, the stress is more evenly transmitted among the second U-shaped seat 231, the first U-shaped seat 211 and the third U-shaped seat, thereby avoiding the relative displacement among the second U-shaped seat 231, the first U-shaped seat 211 and the third U-shaped seat, enhancing the shear strength and bending strength of the connection between the cantilever beam 110 and the beam column 120, and improving the load bearing capacity and durability of the overall structure.

[0050] Preferably, the locking part is a wire or a bundle of steel bars, and the structure of the locking part is not limited in the present application.
