[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example

[0027] Reference Figures 1-4 , a building steel bar connection structure, comprising:

[0028] Sleeve 1, both sides of the surface of the sleeve 1 are provided with external threads, and the top and bottom of the sleeve 1 are provided with openings;

[0029] The threaded sleeves 2 are movably mounted on both sides of the sleeve 1. The inner cavity of the threaded sleeves 2 is adapted to the external thread. The two threaded sleeves 2 are provided with sliding grooves on opposite sides.

[0030] A fixing box 10 is fixedly installed in the inner cavity of the opening;

[0031] The fixing mechanism is located in the inner cavity of the fixing box 10 and is used for quickly connecting the building steel bars.

[0032] As a preferred solution of the present invention, the fixing mechanism includes: two limiting rods 3, two sliding sleeves 4, four inclined blocks 5, four guide plates 6, four guide rods 7 and four pulleys 8;

[0033] The limiting rod 3 is fixedly installed in the inner cavity of the fixed box 10, and the sliding sleeve 4 is slidably sleeved on the surface of the limiting rod 3. Both sides of the limiting rod 3 are fixedly connected to the inclined block 5. Both sides of the inner cavity of the fixed box 10 are slidably connected to the guide plate 6. The opposite sides of the two guide plates 6 are fixedly connected to the guide rod 7. The ends of the two guide rods 7 away from the guide plate 6 are rotatably connected to the pulley 8, and the pulley 8 is slidably set in the inner cavity of the slide groove.

[0034] Limit openings are provided on both sides of the opposite sides of the two fixing boxes 10, and the limit openings are adapted to the inclined block 5. By rotating the threaded sleeve 2, the pulley 8 is driven to rotate, the pulley 8 drives the guide rod 7 to move, the guide rod 7 drives the guide plate 6 to move, and the guide plate 6 drives the inclined block 5 to move. When the inclined block 5 moves, it contacts the building steel bars, so that the building steel bars can be quickly fixed and connected.

[0035] As a preferred solution of the present invention, limiting openings are provided on both sides of the opposite sides of the two fixing boxes 10, and the limiting openings are adapted to the inclined blocks 5. By providing the limiting openings, the inclined blocks 5 can be conveniently positioned for the steel bars.
