[0028] Specifically, the vertical stress beam concrete 1 is used to support the vertical steel reinforcement frame 3 to improve crack resistance and toughness. The vertical steel reinforcement frame 3 is used to support the composite vertical beam column 5 to prevent collapse. The horizontal stress beam concrete 2 is used to support the horizontal steel reinforcement frame 4 to prevent deformation and cracking. The horizontal steel reinforcement frame 4 is used to support the composite horizontal beam column 15 to prevent collapse. The composite vertical beam column 5 is used to support the inclined plate 6 for fixation. The inclined plate 6 is used to support the shell 7 for fixation.

[0029] Reference Figures 4-6 The sliding assembly includes a connecting rod 10, the outer wall of which is slidably connected to the inside of the baffle 8. A spring 9 is fixedly connected to the outer wall of the connecting rod 10, and a fixing block 11 is fixedly connected to the outer wall of the connecting rod 10. A support rod 12 is rotatably connected to the outer wall of the fixing block 11. The outer wall of the spring 9 is located on the outer wall of the baffle 8, and the outer wall of the support rod 12 is located inside the composite vertical beam column 5. The outer wall of the outer shell 7 is provided with a thread 13, and a rotating block 14 is rotatably connected to the outer wall of the thread 13. The outer wall of the rotating block 14 is located on the outer wall of the inclined plate 6, and the outer wall of the rotating block 14 is fixedly connected to the inside of the horizontal stress beam concrete 2. The outer wall of the connecting rod 10 is fixedly connected to the inside of the horizontal stress beam concrete 2, and the outer wall of the outer shell 7 is fixedly connected to the inside of the horizontal stress beam concrete 2.

[0030] Specifically, the outer shell 7 supports the connecting rod 10 for sliding, the connecting rod 10 drives the spring 9 for compression, the baffle 8 supports the connecting rod 10 for sliding, the connecting rod 10 drives the fixing block 11 for sliding, the fixing block 11 drives the support rod 12 for rotation, the support rod 12 is used to fix the stacked beam-column 5 and the inclined plate 6 to prevent collapse, and the rotating block 14 is used to fix the outer shell 7 and the inclined plate 6 to prevent movement. This allows for the rapid installation of the stacked beam-column joint. The rapid installation device enables the rapid positioning and connection of the beam-column joint.

[0031] Reference Figures 5-7The outer wall of the inclined plate 6 is fixedly connected to the composite beam column 15. The interior of the composite beam column 15 is provided with an L-shaped support plate 21. The outer wall of the L-shaped support plate 21 is provided on the outer wall of the composite vertical beam column 5. The outer wall of the composite beam column 15 is fixedly connected to the interior of the horizontal stress beam concrete 2. The outer wall of the composite beam column 15 is fixedly connected to the interior of the horizontal steel reinforcement frame 4. The composite beam column 15 includes a first glass fiber 16, a first carbon fiber cloth 17, a steel frame 18, a second carbon fiber cloth 19, and a second glass fiber 20.

[0032] Specifically, the first glass fiber 16 has high tensile strength and can withstand large tensile forces. In beam-column joints, it can work together with concrete to share the tensile force, improve the tensile strength of the joint, and reduce the possibility of cracks caused by tensile forces. The first carbon fiber cloth 17 has good chemical stability and is almost unaffected by the corrosion of chemicals such as acids, alkalis, and salts. In prefabricated structures, the use of carbon fiber cloth can avoid corrosion damage to beam-column joints caused by environmental factors. The steel frame 18 has high strength and stiffness. Setting the steel frame 18 at the composite beam-column joint can effectively share the bending moment borne by the joint, thereby achieving the effect of strengthening the internal material, better transmitting and distributing internal forces, and making the entire structural system more robust and reliable.

[0033] Working principle: When the prefabricated prestressed composite beam-column joint of a building is required, the connecting rod 10 is pressed to compress the spring 9, thereby causing the connecting rod 10 to slide inside the baffle 8. At the same time, the fixing block 11 slides, causing the support rod 12 to rotate, which in turn causes the outer shell 7 to slide inside the inclined plate 6 and the composite vertical beam-column 5. The rotating block 14 rotates on the outer wall of the thread 13, and then the rotating block 14 is fixed to the outer wall of the inclined plate 6. The L-shaped support plate 21 is used to support and fix the composite vertical beam-column 5 and the composite horizontal beam-column 15 to prevent breakage. This allows for the rapid installation of the composite beam-column joint. The rapid installation device can achieve rapid positioning and connection of the beam-column joint, shortening the installation time of a single joint.

[0034] The first glass fiber 16 supports and fixes the first carbon fiber cloth 17, thereby fixing the steel frame 18, which in turn fixes the second carbon fiber cloth 19 and the second glass fiber 20. This strengthens the internal material and allows for better transmission and distribution of internal forces when subjected to vertical and horizontal loads, making the entire structural system more robust and reliable.
