This connection structure prefabricates beam and column components in the factory and then transports them to the construction site for assembly and connection. Common prefabricated beam-column connection methods include bolt connection and welding connection.

[0003] However, when connecting beams and columns through welding connection and bolt connection, it is rather troublesome, the installation efficiency is low, and it is not convenient for subsequent disassembly of beams and columns.

A connection circular plate is fixedly connected to the top of the vertical beam. Uniformly distributed adjustment screw holes are opened on the outside of the connection circular plate. A rotating sleeve is arranged on the top of the connection circular plate. Adjustment bolts are arranged through the outside of the rotating sleeve and are in threaded connection with the adjustment screw holes. A fixed sleeve is fixedly connected to the top of the rotating sleeve. A plug-in plate is fixedly connected in the middle between the inner walls of the fixed sleeve. Plug-in slots are opened on both the left and right sides of the plug-in plate. Limiting blocks are slidably connected through the front and rear inner walls of the plug-in slots.

An adjustment knob is fixedly connected to the front end of the bidirectional screws. Two nut pairs are threadedly connected through the outside of the plug-in plate. The nut pairs are fixedly connected to the sliding plate. Cross beams are arranged on both the left and right sides of the fixed sleeve. A plug-in block is fixedly connected to the end of the cross beam adjacent to the fixed sleeve. Limiting grooves are opened on both the front and rear sides of the plug-in block. The limiting grooves are slidably connected through the limiting blocks.

[0008] Specifically, arc-shaped plates are arranged on both the left and right sides of the outside of the vertical beam. Two support frames are fixedly connected to the outside of each arc-shaped plate. A bottom support is fixedly connected to the end of the support frame opposite to the arc-shaped plate.

[0022] As Figures 1-5As shown in the figure, the beam-column connection structure of the prefabricated building structure includes a vertical beam 1 and a cross beam 18. A connecting circular plate 16 is fixedly connected to the top of the vertical beam 1. Uniformly distributed adjusting screw holes 17 are formed in the outer part of the connecting circular plate 16.

A sliding plate 22 is fixedly connected to the side of the limiting block 23 opposite to the plugging groove 19, and the sliding plate 22 penetrates and is slidably connected with the plugging plate 12. Two bidirectional screws 20 penetrate and are rotatably connected to the front side of the fixed sleeve 3, and the bidirectional screws 20 penetrate and are rotatably connected with the plugging plate 12. An adjusting knob 4 is fixedly connected to the front end of the bidirectional screw 20. Two nut pairs 21 penetrate and are threadedly connected to the outer part of the plugging plate 12, and the nut pairs 21 are fixedly connected to the sliding plate 22. Cross beams 18 are arranged on both the left and right sides of the fixed sleeve 3. A plugging block 14 is fixedly connected to the end of the cross beam 18 adjacent to the fixed sleeve 3. Limiting grooves 15 are formed on both the front and rear sides of the plugging block 14, and the limiting grooves 15 penetrate and are slidably connected with the limiting blocks 23. The rotating sleeve 2 is sleeved on the connecting circular plate 16, and then the cross beam 18 is inserted into the fixed sleeve 3, so that the plugging block 14 on the cross beam 18 is inserted into the plugging groove 19 on the plugging plate 12. By turning the adjusting knob 4 with a screwdriver to drive the bidirectional screw 20 to rotate, the rotation of the bidirectional screw 20 drives the two nut pairs 21 and the sliding plate 22 connected to the nut pairs 21 to approach each other until the limiting block 23 on the sliding plate 22 is inserted into the limiting groove 15 on the plugging block 14, so that the cross beam 18 can be fixed in the fixed sleeve 3 without welding or a large number of bolts. After the installation is completed, the cross beam 18 is rotated to drive the rotating sleeve 2 to rotate on the connecting circular plate 16. After the rotation is completed, the adjusting bolt 13 is penetrated through the rotating sleeve 2 and screwed into the adjusting screw hole 17, so as to fix the rotating sleeve 2 and the connecting circular plate 16.

[0023] Arc-shaped plates 9 are arranged on both the left and right sides of the outer part of the vertical beam. Two support frames 8 are fixedly connected to the outer parts of the arc-shaped plates 9. A bottom support is fixedly connected to the end of the support frame 8 opposite to the arc-shaped plate, and the inner wall of the bottom support is in contact with the cross beam. After the installation and adjustment are completed, the bottom support 6 is in contact with the bottom of the cross beam 18, and the arc-shaped plate 9 is moved along the cross beam 18 towards the vertical beam 1 until the inner wall of the arc-shaped plate 9 is in contact with the vertical beam 1. Then, the ear plates 10 on the arc-shaped plate 9 are connected through the fourth fixing bolts 11, so as to fix the two arc-shaped plates 9 on the vertical beam 1. The bottom support 6 is in contact with the bottom of the cross beam 18 to realize the support of the cross beam 18.

A spring 25 is fixedly connected between the clamping block 7 and the bottom bracket 6, and the spring 25 is sleeved on the sliding rod 24. The elastic force of the spring 25 enables the two clamping blocks 7 to contact the front and rear sides of the cross beam 18, so as to realize the clamping and support of the cross beam 18 and improve the stability of the cross beam 18. The sliding rod 24 ensures that the spring 25 will not deform when contracting.

[0025] Both the front and rear sides of the arc-shaped plate are fixedly connected with ear plates 10. The outer sides of the ear plates 10 are penetrated and threadedly connected with two fixing bolts 11. By providing the ear plates 10, it is convenient to connect and install the two arc-shaped sleeves 9 with the fourth fixing bolt 11.

[0026] A reinforcing plate 5 is fixedly connected between the rotating sleeve 2 and the fixed sleeve 3. A rubber pad is arranged on the inner wall of the arc-shaped plate, which can increase the friction between the inner wall of the arc-shaped sleeve 9 and the vertical beam 1, thereby improving the stability.

[0027] The working principle of a beam-column connection structure of a prefabricated building structure provided by the present utility model is as follows:

[0028] First, during use, first put the rotating sleeve 2 on the connecting circular plate 16, and then insert the cross beam 18 into the fixed sleeve 3, so that the insertion block 14 on the cross beam 18 is inserted into the insertion slot 19 on the insertion plate 12. Then, turn the adjusting knob 4 with a screwdriver to drive the bidirectional screw rod 20 to rotate. The rotation of the bidirectional screw rod 20 drives the two nut pairs 21 and the sliding plates 22 connected to the nut pairs 21 to approach each other until the limit blocks 23 on the sliding plates 22 are inserted into the limit slots 15 on the insertion blocks 14, so that the cross beam 18 can be fixed in the fixed sleeve 3 without welding or a large number of bolts. After the installation is completed, rotate the cross beam 18 to drive the rotating sleeve 2 to rotate on the connecting circular plate 16. After the rotation is completed, penetrate the adjusting bolt 13 through the rotating sleeve 2 and screw it into the adjusting screw hole 17 to fix the rotating sleeve 2 and the connecting circular plate 16. After the installation and adjustment are completed, contact the bottom bracket 6 with the bottom of the cross beam 18, and move the arc-shaped plate 9 along the cross beam 18 towards the vertical beam 1 until the inner wall of the arc-shaped plate 9 contacts the vertical beam 1. Then, connect the ear plates 10 on the arc-shaped plate 9 with the fixing bolts 11 to fix the two arc-shaped plates 9 on the vertical beam 1. The elastic force of the spring 25 enables the two clamping blocks 7 to contact the front and rear sides of the cross beam 18, so as to realize the clamping and support of the cross beam 18 and improve the stability of the cross beam 18.
