[0004] In existing aluminum alloy load-bearing beam connection technologies, most connection methods cannot ensure a tight fit between beams and columns. Under long-term exposure to large external forces, the beam-column connection is prone to loosening and swaying, which in turn affects the stability and safety of the entire building structure. At the same time, some connection structures are extremely difficult to disassemble after installation. When the building structure needs to be modified, repaired, or components replaced, it is difficult to complete the disassembly work smoothly even with a lot of manpower and time costs, and it may even cause damage to the beams and columns.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, this utility model provides a detachable aluminum alloy load-bearing beam connector, including a connecting frame 1. Multiple expansion mechanisms 3 arranged in a rectangular array are inserted on both sides of the connecting frame 1. Connecting mechanisms 2 are fixedly installed on both sides of the connecting frame 1. A beam-column 4 is provided inside the connecting mechanism 2. The connecting mechanism 2 includes four side frames 22, one end of which is fixedly connected to one side of the connecting frame 1. A connecting cavity 25 is opened on the inner side of the side frame 22. Two surrounding frames 21 are provided on the outer sides of the four side frames 22. A casting cavity 26 is opened on the inner side of the surrounding frame 21. A casting port 23 is opened on one side of one of the surrounding frames 21. The surrounding frames 21 and the side frames 22 are all fitted to one end of the beam-column 4. When connecting the aluminum alloy load-bearing beam, the connecting frame 1 is first placed in a suitable position, and one end of the beam-column 4 is placed inside the connecting mechanism 2. The four side frames 22 surround one end of the beam-column 4, and their inner connecting cavities 25 are initially fitted to the beam-column 4. Next, two enclosure frames 21 are installed, enclosing the side frame 22 and the beam-column 4. The pouring cavity 26 inside the enclosure frame 21 is further fitted to the beam-column 4, while the sealing strips 27 on both sides of the enclosure frame 21 are tightly fitted to the outside of the beam-column 4, providing a sealing effect. Then, a suitable connecting material, such as concrete, is injected into the pouring cavity 26 through the pouring port 23 on one side of one of the enclosure frames 21. After the material solidifies, the sealing block 24 is engaged inside the pouring port 23, completing the connection and fixation of the connecting mechanism 2 to the beam-column 4.

[0024] Specifically, the expansion mechanism 3 includes a fixed cylinder 30. One end of the fixed cylinder 30 passes through one side of the connecting frame 1 and slides against one end of the beam-column 4. Multiple expansion grooves 36 are provided at one end of the fixed cylinder 30. A fixing screw 33 is slidably mounted on the inner side of the fixed cylinder 30, and a fastening nut 31 is fitted onto the outer side of the fixing screw 33. A pull rod 34 is fixed to one end of the fixing screw 33, and an inner support block 35 is fixed to one end of the pull rod 34. The inner support block 35 slides against the inner side of the expansion grooves 36. When one end of the fixed cylinder 30 passes through one side of the connecting frame 1 and slides against one end of the beam-column 4, the multiple expansion grooves 36 at one end of the fixed cylinder 30 are in an unexpanded state. The fixing screw 33 is inserted into the inner side of the fixed cylinder 30, and an anti-loosening washer 32 is fitted onto the outer side of the fixing screw 33 before tightening the fastening nut 31. As the fastening nut 31 is tightened, the pull rod 34 at one end of the fixing screw 33 drives the inner support block 35 to move towards the end of the fixing cylinder 30 where the expansion groove 36 is located. The inner support block 35 slides and fits against the inner side of the expansion groove 36, gradually opening the expansion groove 36 and making the connection between the fixing cylinder 30 and the connecting frame 1 and the beam column 4 more stable. The anti-slip texture 37 at one end of the fixing cylinder 30 increases the friction with the connection parts, and because the fixing cylinder 30 is a malleable cylinder, it can better adapt to the connection requirements of different shapes and sizes. When disassembly is required, loosen the fastening nut 31, remove the fixing screw 33, and the expansion groove 36 returns to its original shape, allowing for easy disassembly.

[0025] Furthermore, the multiple reinforcing bars 5 installed on the inner side of the beam and column 4 can significantly enhance the strength and load-bearing capacity of the beam and column 4. When subjected to large external forces, the reinforcing bars 5 can effectively disperse and transfer stress, preventing the beam and column 4 from breaking or deforming due to excessive stress, thereby ensuring the stability and safety of the entire building structure.

[0026] Furthermore, the sealing strips 27 fixed on both sides of the enclosure frame 21 have their inner sides tightly fitted to the outer sides of the beam and column 4, providing a good sealing effect. When the connecting material is injected into the pouring cavity 26, it can prevent the material from leaking from the gap between the enclosure frame 21 and the beam and column 4, ensuring the filling effect of the connecting material and improving the tightness and stability of the connection between the connecting mechanism 2 and the beam and column 4.

[0027] It is worth noting that the sealing block 24, which engages inside the pouring opening 23, can promptly seal the pouring opening 23 after the connecting material is injected into the pouring cavity 26. This prevents external dust, moisture, and other impurities from entering the pouring cavity 26, avoiding affecting the quality and performance of the connecting material and ensuring the long-term stability of the connection between the connecting mechanism 2 and the beam-column 4.

[0028] It is worth noting that the anti-loosening washer 32 sleeved on the outside of the fixing screw 33 can increase the friction between the fixing screw 33 and the fastening nut 31 when the fastening nut 31 is tightened. During long-term use, it can effectively prevent the fastening nut 31 from loosening due to vibration, external force and other factors, and ensure that the expansion mechanism 3 can always maintain a stable and reliable fixing effect on the connecting frame 1 and the beam column 4.

[0029] It is worth mentioning that the multiple equally spaced anti-slip grooves 37 fixed at one end of the fixing cylinder 30 can increase the friction between the fixing cylinder 30 and the connecting parts such as the connecting frame 1 and the beam column 4. During the fixing process of the expansion mechanism 3, it can prevent the fixing cylinder 30 from sliding and improve the accuracy of fixing; during use, it can also enhance the stability of fixing and reduce the problem of loosening of the connection due to sliding.

[0030] It is worth emphasizing that the fixing cylinder 30 adopts a malleable cylinder design, giving it good flexibility and adaptability. In different application scenarios, facing connection parts of different shapes and sizes, the malleable cylinder can deform to a certain extent according to the actual situation, better fit the connection parts, thereby achieving a more stable fixation and expanding the application range of the expansion mechanism 3.

[0031] Working Principle: When connecting aluminum alloy load-bearing beams, first place the connecting frame 1 in a suitable position, and place one end of the beam / column 4 inside the connecting mechanism 2. Four side frames 22 surround one end of the beam / column 4, and their inner connecting cavities 25 initially fit against the beam / column 4. Next, install two surrounding frames 21, so that the surrounding frames 21 enclose the side frames 22 and the beam / column 4. The pouring cavity 26 inside the surrounding frames 21 further fits against the beam / column 4, while the sealing strips 27 on both sides of the surrounding frames 21 fit tightly against the outside of the beam / column 4, providing a sealing effect. Then, inject suitable connecting material, such as concrete, into the pouring cavity 26 through the pouring port 23 on one side of one of the surrounding frames 21. After the material solidifies, the sealing block 24 is engaged inside the pouring port 23, completing the connection and fixation of the beam / column 4 by the connecting mechanism 2.

[0032] One end of the fixing cylinder 30 is inserted through one side of the connecting frame 1 and slidably fitted against one end of the beam-column 4. At this time, the multiple expansion grooves 36 at one end of the fixing cylinder 30 are in an unexpanded state. The fixing screw 33 is inserted into the inside of the fixing cylinder 30, and after the anti-loosening washer 32 is put on the outside of the fixing screw 33, the fastening nut 31 is tightened. As the fastening nut 31 is tightened, the pull rod 34 at one end of the fixing screw 33 drives the inner support block 35 to move towards the end of the fixing cylinder 30 where the expansion groove 36 is opened. The inner support block 35 slides against the inside of the expansion groove 36, gradually opening the expansion groove 36, making the connection between the fixing cylinder 30 and the connecting frame 1 and the beam-column 4 more stable. The anti-slip texture 37 at one end of the fixing cylinder 30 can increase the friction with the connection part, and since the fixing cylinder 30 is a malleable cylinder, it can better adapt to the connection requirements of different shapes and sizes. When disassembly is required, loosen the fastening nut 31, remove the fixing screw 33, and the expansion groove 36 returns to its original state, so that it can be easily disassembled.
