[0032] The second connecting tube 4 includes a third connecting tube 8 and a fourth connecting tube 9 sleeved on the outside thereof. The inner diameter of the fourth connecting tube 9 is equal to the outer diameter of the third connecting tube 8, and the inner wall of the fourth connecting tube 9 is not threaded, so that it can be inserted into the third connecting tube 8. The upper end of the third connecting tube 8 is provided with an inverted Y-shaped groove 12, and the lower end is provided with a threaded hole 13 axially connected to the inverted Y-shaped groove 12. The centers of the inverted Y-shaped groove 12 and the threaded hole 13 coincide, and the threaded hole 13 is connected to the second steel bar 5. The inverted Y-shaped groove 12 is arranged to penetrate along the diameter direction of the third connecting tube 8, and the diameter of the threaded hole 13 is smaller than the width of the end connected to it in the inverted Y-shaped groove 12, which is convenient for the insertion of the connecting column 3 and can also limit the axial position of the connecting column 3.

[0033] The connecting column 3 includes a connecting column 7 and a connecting block 11 at the lower end thereof, the two forming an inverted T-shaped structure, matched with an inverted Y-shaped groove 12, the projection of the connecting block 11 on the horizontal plane is a circle cut off two arcs along two symmetrical chords, and the diameter of the circle is smaller than the outer diameter of the third connecting tube 8. The sliding plug-in cooperation between the lower end of the connecting column 3 and the second connecting tube 4 is the sliding plug-in cooperation between the connecting block 11 and the lower end of the connecting column 7 and the inverted Y-shaped groove 12 at the upper end of the third connecting tube 8, and the lower end of the third connecting tube 8 is threadedly connected to the second steel bar 5.

[0034] The first connecting tube 2 is a connecting tube 6 with a threaded interface 10 at the center. The upper end of the connecting tube 6 is threadedly connected to the first steel bar 1. The upper end of the connecting column 7 is provided with an external thread to achieve a threaded connection between the upper end of the connecting column 7 and the lower end of the connecting tube 6.

[0035] In the connection device, the connection tube 6 is used to connect the first steel bar 1 and the connection column 3, the connection column 3 and the third connection tube 8 are inserted and connected together, and then the fourth connection tube 9 is inserted to limit the range of movement of the connection column 3 and leave a certain adjustment margin.

[0042] (5) The upper prefabricated component falls down, and the first steel bar 1 is aligned with the connecting column 7. After adjusting the distance, the connecting tube 6 is screwed out upward and connected to the first steel bar 1. Since the connecting column 7 and the connecting block 11 can slide in the third connecting tube 8, the first steel bar 1 can have a deviation adjustment margin, that is, the first steel bar 1 and the second steel bar 5 are misaligned, and the two can also be connected;

[0043] (6) After the connection is fixed, the reinforcing bar glue is poured into the connection part of the connection column 7, the connection block 11 and the third connection tube 8 to fix it;
