[0043] In the field of building steel bar connection, the two steel bars to be connected are often misaligned. For example, when connecting steel cages or installing modules, the two steel bars to be connected are often not coaxial, that is, misaligned, which brings great difficulties to the steel bar connection. At present, there are two ways to solve this problem: one is to expand the steel bar sleeve, and the other is to manually correct the two steel bars when connecting.

[0047] like Figure 7In the assembled structural node shown in the figure, the steel bars on the left component and the steel bars on the right component are misaligned with each other. In order to connect these misaligned steel bars, the steel bar straightener is fixed to a suitable position, and the two mutually misaligned steel bars on the assembled structural node are first clamped into the jaws 401 of the two clamps 400 respectively, and the connecting nut 001 is screwed into one of the two misaligned steel bars, and then the driving device 100 drives the scissor mechanism 200 to close, and the scissor mechanism 200 drives the jaws 401 of the two clamps 400 to align the misaligned steel bars, so that the two misaligned steel bars are bent to the same axis, and then the connecting nut 001 is screwed into the connecting nut 001. Unscrew it to connect the two steel bars, fix the stress reliever to a suitable position, so that the connecting nut 001 and the steel bar are placed in the receiving groove 012 of the high-frequency heater 002, and the two steel bars bent on the same axis are heated by the high-frequency heater 002 to eliminate the residual stress between the two steel bars. The temperature sensor 003 is used to monitor the heating temperature of the high-frequency heater 002.

The first transverse movement slider is threadedly connected to the first transverse movement adjustment screw. The first transverse movement slider is fixed on the base plate.

5. The assembled structural node correction device according to claim 4 is characterized in that: The first lifting slider is provided with a second guide rod, the extension direction of the second guide rod is the same as the extension direction of the first transverse adjustment screw, the first transverse slider is provided with a second guide channel, and the second guide rod is slidably assembled in the second guide channel.

6. The assembled structural node correction device according to claim 1 is characterized in that: The stress reliever also includes a second transverse movement mechanism, which includes a second transverse movement adjustment screw and a second transverse movement slider. The second transverse movement adjustment screw is rotatably mounted on the second lifting slider. The second transverse movement slider is threadedly connected to the second transverse movement adjustment screw. The high-frequency heater is mounted on the second transverse movement slider through a connecting piece.

7. The assembled structural node correction device according to claim 1 is characterized in that: A third guide rod is provided on the second base, and the extension direction of the third guide rod is the same as the extension direction of the second lifting adjustment screw rod. A third guide channel is provided on the second lifting slider, and the third guide rod is slidably assembled in the third guide channel.

8. The assembled structural node correction device according to claim 6, characterized in that: The second lifting slider is provided with a fourth guide rod, the connecting member is provided with a fourth guide channel, the extension direction of the fourth guide rod is the same as the extension direction of the second transverse adjustment screw, and the fourth guide rod is slidably assembled in the fourth guide channel.

9. A method for correcting a prefabricated structure node, characterized in that: The use of the assembled structure node correction device according to any one of claims 1 to 8 comprises the following steps: Clamp two mutually displaced steel bars on the assembled structure node into the jaws of two clamps respectively; Screw the connecting nut onto one of the steel bars; The driving device drives the scissor mechanism to close, and the scissor mechanism drives the two clamps to move closer to each other and align them so as to bend the two misaligned steel bars to the same axis; Rotate the connection nut on the rebar to connect it to another rebar; Remove the steel bar straightener; Adjust the high-frequency heater to a suitable position, place the connecting nut and the steel bar in the receiving groove of the high-frequency heater, and heat it to eliminate the residual stress at the connection between the two steel bars.
