A plurality of insertion rods are arranged at intervals along the vertical direction on one side of the crossbeam relative to the column, and the column has insertion holes for the corresponding insertion of the insertion rods.

[0006] Above the insertion hole, a through groove is opened in the column along the vertical direction. A moving plate is slidably connected inside the through groove. An intercepting rod is located inside the column and is fixedly connected to the moving plate. The insertion rod has a through hole for the intercepting rod to be inserted into. A plurality of support bars are arranged between the bottom of the crossbeam and the column.

[0007] The further improved solutions in the above technical scheme are as follows:

[0008] 1. In the above solution, one end of the moving plate located outside the column is connected with an adjusting handle.

[0009] 2. In the above solution, the length of the through groove is greater than the length of the intercepting rod.

[0011] 4. In the above solution, several clamping openings for the support bars to be inserted are arranged below the jack.

[0012] 5. In the above solution, the support bar has a connection block that cooperates with the clamping opening.

[0013] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0014] For the prefabricated steel structure joint of the utility model, several insertion rods are arranged at intervals in the vertical direction on one side of the cross beam relative to the column. A moving plate is slidably connected inside the through groove. The intercepting rod is located inside the column and fixedly connected to the moving plate. The insertion rod has a through hole for the intercepting rod to be inserted. The cross beam is connected to the column by inserting several insertion rods into the jacks of the column and inserting the intercepting rod located inside the column into the through holes of the insertion rods. Further, several insertion rods are arranged at intervals in the vertical direction on one side of the cross beam relative to the column, and the column has jacks for the corresponding insertion of the insertion rods.
