[0024] The concrete column 1 is provided with a column steel reinforcement cage 2, which enhances the crack resistance and integrity of the concrete column 1. The connecting bar 3 is embedded in the concrete column 1 and partially extends out of the concrete column 1. The first connecting sleeve 9 is arranged at one end of the connecting bar 3 extending out of the concrete column 1. The concrete beam 5 is provided with a beam steel reinforcement cage, which enhances the crack resistance and integrity of the concrete beam 5. The beam steel reinforcement cage includes the prestressed main bar 6 and the stirrup. The prestressed main bar 6 can effectively improve the bearing capacity of the concrete beam 5, that is, significantly improve the bending resistance and bearing capacity of the concrete beam 5, so that the concrete beam can better resist deformation and damage when bearing external load, thereby prolonging the service life of the structure. Moreover, the prestressed main bar 6 is also beneficial to enhancing the crack resistance of the concrete beam 5. By pre-applying pressure stress, when the concrete beam 5 bears external load, the pre-pressure first offsets the tensile stress in the concrete, thereby delaying or reducing the occurrence and expansion of cracks. This makes the concrete beam 5 more stable and safe during use. The prestressed main bar 6 partially extends out of the concrete beam 5, and the second connecting sleeve 8 is arranged at one end of the prestressed main bar 6 extending out of the concrete beam 5. The connecting column 7 is used for connecting the first connecting sleeve 9 and the second connecting sleeve 8 to realize the connection of the prestressed main bar 6 and the connecting bar 3. The second connecting sleeve 8 not only has the function of connecting the second connecting sleeve 8, but also has the function of connecting the tensioning plate to tension the prestressed main bar 6, that is, the outer side of the second connecting sleeve 8 is also provided with external threads for connecting the tensioning plate. The large-diameter end and the small-diameter end of the connecting column 7 are both provided with external threads.

Moreover, the arrangement of the large-diameter end can improve the stability and safety of the connection between the concrete beam 5 and the concrete column 1, the large-diameter end can better disperse and bear the tension and pressure, improve the durability and service life of the connection between the concrete beam 5 and the concrete column 1, and improve the reliability of the connection between the concrete beam 5 and the concrete column 1.

The corbel 4 is a concrete structure integrally formed with the concrete column 1, while the corbel frame is a reinforced steel structure. The corbel frame not only enhances the crack resistance and integrity of the corbel 4, but also effectively restrains the development of cracks in the corbel 4 under stress. In practical applications, especially under tension, compression, and deformation, the corbel frame can distribute stress more evenly to all parts. The corbel 4 is used to temporarily support the concrete beam 5, that is, the concrete beam 5 is hoisted onto the corbel 4, then connected to the prestressed main reinforcement 6 and connecting reinforcement 3, and then the post-pouring operation is carried out.
