[0020] The existing connection structure is not convenient for finding the installation position between the beam and the column, which prolongs the assembly time of the staff. When continuously operating on the prefabricated building, the work efficiency is reduced.

[0021] In view of this, a beam-column connection structure for prefabricated buildings is provided. Through the cooperation among the cross beam, the back plate and the square plate, the positioning of the cross beam is realized, which is convenient for the user to find the installation position of the cross beam, and there is no need for external facilities to continuously align the connection position for connection, solving the problems that the existing connection structure is not convenient for finding the installation position between the beam and the column, prolonging the assembly time of the staff, and reducing the work efficiency when continuously operating on the prefabricated building.

[0022] Through the personnel in this field, the components in this case are connected in sequence. For the specific connection and operation sequence, the following working principle should be referred to. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0023] Embodiment 1: As Figures 1-4 It can be seen that a beam-column connection structure for prefabricated buildings includes a column body 1. A first annular plate 2 and a second annular plate 4 are welded on the outer side of the column body 1. A positioning mechanism is arranged inside the first annular plate 2 and the second annular plate 4. The positioning mechanism includes a positioning groove 19, a cross beam 5, a bent plate 14, a rotating rod 13, a baffle 12 and a back plate 11. Two positioning grooves 19 are respectively opened on the inner sides of the first annular plate 2 and the second annular plate 4. A cross beam 5 is movably connected inside the two positioning grooves 19. A back plate 11 is attached to the top of the cross beam 5. A baffle 12 is attached to the outer side of the back plate 11. A rotating rod 13 is fixedly connected to one side of the baffle 12. A bent plate 14 is rotationally connected to the outer side of the rotating rod 13 through a pin shaft. The bottom of the bent plate 14 is fixedly connected to the top of the first annular plate 2;

[0024] In the specific implementation process, it is particularly pointed out that through the cooperation among the rotating rod 13, the baffle 12 and the back plate 11, the positioning of the cross beam 5 is realized, which is convenient for the user to find the installation position of the cross beam 5, and there is no need for external facilities to continuously align the connection position for connection, solving the problems that the existing connection structure is not convenient for finding the installation position between the beam and the column, prolonging the assembly time of the staff, and reducing the work efficiency when continuously operating on the prefabricated building.

[0025] Furthermore, a spring 15 is arranged on the top pin shaft of the rotating rod 13, and the two ends of the spring 15 are fixedly connected to the top of the rotating rod 13 and the bent plate 14 respectively;

[0026] In the specific implementation process, it is particularly noted that the elastic deformation of the spring 15 can drive the baffle 12 to always fit against the outer side of the back plate 11 for limiting;

[0027] Furthermore, a second square plate 17 is fixedly connected to the lower side of one side of the back plate 11, and one side of the second square plate 17 is fixedly connected to the upper side of the cross beam 5 through a screw 18;

[0028] In the specific implementation process, it is particularly noted that the screw 18 on the second square plate 17 is used to fix the back plate 11, ensuring the stability of the back plate 11;

[0029] Specifically, when using this connection structure for beam and column of prefabricated building, the user can first rotate the rotating rod 13 by 90 degrees, then align the external cross beam 5 with the positioning grooves 19 on the first annular plate 2 and the second annular plate 4 and place it in. After it is completely placed, release the rotating rod 13. At this time, the elastic deformation of the spring 15 can drive the baffle 12 to always fit against the outer side of the back plate 11 for limiting, and can temporarily fix the cross beam 5, facilitating the user to weld or install rivets subsequently.

[0030] Embodiment 2: From Figure 1 and 3 it can be seen that a cylinder 9 is fixedly connected to the inner side of the column 1 through multiple connecting rods 10. A connecting plate 16 is fixedly connected to the bottom of the first annular plate 2. A first square plate 7 is fixedly connected to one side of the connecting plate 16. The rear of the first square plate 7 is fixedly connected to the outer side of the cross beam 5 through multiple rivets 6;

[0031] In the specific implementation process, it is particularly noted that multiple rivets 6 can be used to connect the column 1 and the cross beam 5;

[0032] Furthermore, multiple metal rods 3 are welded to the inner sides of the first annular plate 2 and the second annular plate 4. The upper side of the first annular plate 2 is fixedly connected to the outer side of the column 1 through a reinforcing rib 8;

[0033] In the specific implementation process, it is particularly noted that multiple metal rods 3 improve the strength between the first annular plate 2 and the second annular plate 4, and the reinforcing rib 8 improves the longitudinal strength of the cross beam 5;

[0034] Specifically, on the basis of the above Embodiment 1, through the cooperation among the first annular plate 2, the second annular plate 4 and the metal rod 3, connecting rods 10 and a cylinder 9 are arranged on the inner wall of the column 1 for support to ensure the compressive strength of the column 1. The reinforcing rib 8 between the column 1 and the first annular plate 2 improves the strength of the connection position, thereby improving the overall stability of the connection structure.
