DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0046] Embodiment 1

[0047] Please refer to Figure 4 , Figure 5 , Figure 8 and Figure 10 , the present application provides a technical solution: a prefabricated prestressed beam and cast-in-place concrete beam connecting joint, comprising a connecting assembly clamped outside the concrete beam 1 and connected with the prestressed beam 2, the connecting assembly comprising a metal card sleeve 3, the metal card sleeve 3 is clamped outside the concrete beam 1, and a support assembly for supporting and fixing the prestressed beam 2 is installed outside the metal card sleeve 3 and on the outer side of the concrete beam 1; by providing the support assembly, the prestressed beam 2 can be directly supported and fixed.

[0048] Specifically, the prestressed beam 2 is provided with a metal sleeve 4 at both ends, and the prestressed beam 2 is connected with the support assembly through the metal sleeve 4 at both ends. The metal sleeve 3 comprises a bearing part 21 and a connecting part 5 arranged on both sides of the bearing part 21. The top of the concrete beam 1 is provided with a first clamping groove 6 matched with the bearing part 21. The bearing part 21 is arranged in the first clamping groove 6, and the inner side of the connecting part 5 is attached to the side of the concrete beam 1. The first clamping groove 6 is arranged to mount the bearing part 21 of the metal sleeve 3. The first clamping groove 6 can limit the bearing part 21 to prevent the metal sleeve 3 from deviating and improve the stability of the connection.

[0049] Further, the support assembly comprises a support plate 7 arranged on the side of the connecting part 5 away from the concrete beam 1. The bottom of the metal sleeve 4 is connected with the top of the support plate 7. The bottom of the metal sleeve 4 is provided with a protruding block 8. The top of the support plate 7 is provided with a groove 9 matched with the protruding block 8. The protruding block 8 is slidingly arranged in the groove 9. When the prestressed beam 2 is suspended and installed by the suspension equipment, the groove 9 and the protruding block 8 can facilitate the alignment of the installation position of the prestressed beam 2.

[0050] The prestressed beam 2 is also a reinforced concrete structure and is prefabricated. Thus, the concrete structure at both ends of the prestressed beam 2 is prone to wear and tear and unevenness, which makes it difficult to install the prestressed beam 2 with the concrete beam 1. Therefore, the metal sleeve 4 with regular shape is arranged at both ends of the prestressed beam 2. The metal sleeve 4 can not only prevent wear and tear at both ends of the prestressed beam 2, but also facilitate the alignment of the connecting part 5 made of metal material, thereby improving the stability and convenience of the connection.

[0051] Specifically, the bottom of the support plate 7 is provided with a triangular block 10. One side of the triangular block 10 is connected with the surface of the connecting part 5. The metal sleeve 4 and the connecting part 5 are provided with a positioning block 11. The support plate 7 can support both ends of the prestressed beam 2. The triangular block 10 can improve the support strength of the support plate 7.

[0052] It is worth noting that after the prestressed beam 2 is contacted with the connecting part 5 and the support plate 7 through the metal sleeve 4 and is moved to the installation position, the metal sleeve 4 and the connecting part 5 can be connected through the positioning block 11. Since the metal sleeve 4 and the connecting part 5 are both made of metal material, the connection mode can be bolt connection and welding. Thus, drilling and damage to the outside of the concrete beam 1 and the prestressed beam 2 are avoided, the construction difficulty is reduced, and the convenience and stability of the connection are improved.

[0053] Further, the top of the concrete beam 1 is embedded with four sets of dispersion assemblies for dispersing pressure, and the dispersion assemblies are installed in two groups on both sides of the metal sleeve 3. The dispersion assemblies include four first steel bars 12, which are symmetrically welded in two groups on both sides of the bearing part 21, and the outside of the first steel bar 12 is sleeved with a steel sleeve 13. The top of the outside of the steel sleeve 13 is integrally formed with a groove-shaped eave, and the top of the concrete beam 1 is provided with a second clamping groove 14 matched with the steel sleeve 13, the steel sleeve 13 is embedded in the second clamping groove 14, and the gap between the steel sleeve 13 and the second clamping groove 14 is filled with a silicone sealant layer 15. The second clamping groove 14 is arranged to facilitate the installation of the steel sleeve 13, and the embedded mode improves the firmness of the installation. At the same time, the silicone sealant layer 15 can fill the gap between the steel sleeve 13 and the second clamping groove 14, improve the connection effect and firmness between the steel sleeve 13 and the second clamping groove 14.

[0054] In addition, the bottom of the bearing part 21 and the inside of the first clamping groove 6 are both provided with a rough surface, and the silicone sealant layer 15 is filled between the bearing part 21 and the first clamping groove 6, which can better connect the bearing part 21 and the first clamping groove 6.

[0055] In addition, the bottom of the steel sleeve 13 is provided with a support block 16, the bottom of the support block 16 is attached to the bottom of the inner cavity of the second clamping groove 14, the outside of the groove-shaped eave is attached to the inner wall of the second clamping groove 14, and the bottom of the steel sleeve 13 and the surface of the groove-shaped eave are both provided with an injection hole 17. The groove-shaped eave can prevent the silicone sealant layer 15 from overflowing and improve the sealing of the connection.

[0056] It is worth noting that the support plate 7 and the connecting part 5 directly bear the gravity from the prestressed beam 2, but since the connecting part 5 and the bearing part 21 are integrally formed, the connecting part 5 will transmit the pressure to the bearing part 21, and the first steel bar 12 directly connected to the bearing part 21 is embedded in the inside of the steel sleeve 13, so that when the first steel bar 12 is under pressure, the pressure can be evenly transmitted to the steel sleeve 13, and then dispersed by the steel sleeve 13, thereby increasing the stress area of the concrete beam 1, which can reduce the local pressure and improve the overall bearing effect of the concrete beam 1.

The tripod 18 is made of high-strength metal material, and the triangular structure has good stability.

[0060] Specifically, the top of the tripod 18 is provided with a connecting rod 19 at equal intervals, the top of the connecting rod 19 extends above the first steel 12, the first steel 12 is internally provided with a connecting column 20, and the top of the connecting column 20 is connected with one end of the connecting rod 19. By arranging the connecting column 20 and the connecting rod 19, the tripod 18 can be connected with the first steel 12. Firstly, the tripod 18 is arranged on both sides of the concrete beam 1, which can improve the tightness and firmness of the connection between the metal card sleeve 3 and the concrete beam 1, and secondly, when the first steel 12 is subjected to pressure, the pressure can be transmitted to the tripod 18 through the connecting rod 19 and the connecting column 20, which can further disperse the pressure and improve the load-bearing performance of the concrete beam 1 to prevent local excessive stress from causing collapse.

[0061] The top of the metal card sleeve 3 is provided with a reinforcing assembly, the two sides of the reinforcing assembly are provided with a diagonal bracing assembly, and the diagonal bracing assembly is connected with the top of the reinforcing assembly.

By arranging the first screw rod 24 and the first screw sleeve 25, the second steel 22 can be connected and fixed with the load-bearing part 21.

[0062] In addition, by arranging the V-shaped frame 27 and the third section steel 28 to reinforce the second section steel 22, three-dimensional bearing is achieved, and the bearing effect and the compression resistance of the prestressed beam 2 are further improved. In addition, in the embodiment 1, the prestressed beam 2 is connected and fixed with the concrete beam 1 by the support assembly, and in the embodiment, the prestressed beam 2 can be further connected and fixed with the concrete beam 1 by the reinforcing assembly, which is suitable for high-strength building requirements, such as some factory buildings and factory warehouses.

S5. Installation of connection nodes: After demolding, install the connection nodes into the predetermined positions on the concrete beam. S6. The prestressed beam is connected to the connection node using a suspension device, and further fixing and testing are carried out after the connection is completed. Finally, the connection between the prestressed beam and the concrete beam is completed.
