After the binding is completed, the beam steel bars are dropped into the beam formwork as a whole. At this time, the frame column formwork has been supported. There are many quality problems in the construction, such as uneven spacing in the node area, insufficient quantity, and stirrups overlapping each other, resulting in a long distance without stirrups for the column longitudinal reinforcement. The longitudinal reinforcement may be burned short or burned due to the hooks, resulting in insufficient anchorage length. Utility Model Content

[0006] Furthermore, a lower surface of one of the stirrup clamps is fixedly connected to a limiting support rod, and an inner wall of the limiting support rod is fixedly connected to a limiting block.

[0007] Furthermore, a plane bearing is fixedly connected to the bottom end of the limiting support rod, and the limiting support rod is rotatably connected to a nut via the plane bearing.

[0008] Furthermore, the inner thread of the nut is connected to a bottom rod, and the bottom end of the bottom rod is fixedly connected to a base.

[0009] Furthermore, a limiting groove matched with the limiting support rod is formed on the surface of the bottom rod.

[0011] The utility model provides a tool for improving the one-time qualified rate of stirrup installation at beam-column nodes, and has the following beneficial effects:

[0012] During use, personnel can adjust the spacing of the stirrup clamps according to the preset distance of the beam-column nodes by turning the knobs on the positive and negative screw rods to make it meet the preset distance of the beam-column nodes, and then place multiple devices around the beams and columns, and fix the node stirrup positions around the beams and columns by putting the stirrup clamps on the node stirrups.
