Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figures 1 to 3This utility model provides a technical solution: a steel structure connector for construction, including a column 1, a mounting base 2 fixedly connected to the top of the column 1, an I-beam horizontal steel 3 mounted on the top of the mounting base 2, a double-acting screw 4 rotatably connected inside the mounting base 2, an adjusting slide plate 8 symmetrically threaded to the outer side of the double-acting screw 4, the adjusting slide plate 8 being slidably connected to the mounting base 2, a clamping box 10 fixedly connected to the top of the adjusting slide plate 8, a sliding inner plate 11 slidably connected inside the clamping box 10, and a fixed top of the sliding inner plate 11... A fixed top plate 12 is fixedly connected to the fixed top plate 12. A limiting slide plate 14 is slidably connected inside the fixed top plate 12. A sliding plate 15 is fixedly connected to one side of the limiting slide plate 14. The sliding plate 15 is slidably connected to the fixed top plate 12. An mounting plate 16 that mates with the I-shaped horizontal steel 3 is fixedly connected to one side of the sliding plate 15. The mounting plate 16 and the I-shaped horizontal steel 3 are fixedly installed by mounting bolt No. 17. The fixed top plate 12, the sliding inner plate 11, and the clamping box 10 are all provided with mounting through holes 19. A mounting through hole 19 is provided above the fixed top plate 12. A second mounting bolt 18 is provided to mate with the mounting through hole 19. The adjusting slide plate 8 has a mounting threaded hole 20 inside that mates with the second mounting bolt 18. Fixed side plates 9 are fixedly connected to both sides of the mounting base 2. The fixed side plates 9 have openings 23 inside that mate with the second mounting bolt 18. A limiting nut 21 is provided below the fixed side plates 9 to mate with the second mounting bolt 18. The second mounting bolt 18 enters the mounting through hole 19 in the fixed top plate 12, the sliding inner plate 11, and the clamping box 10. Then, rotate the No. 2 mounting bolt 18, and thread the No. 2 mounting bolt 18 into the mounting threaded hole 20. Move the No. 2 mounting bolt 18 downward through the opening 23, and press the top nut of the No. 2 mounting bolt 18 against the top of the fixed top plate 12, pressing and fixing the fixed top plate 12 and the I-shaped horizontal steel 3. Then, install the No. 2 mounting bolt 18 on the outside thread through the limit nut 21. The top of the limit nut 21 presses against the bottom of the fixed side plate 9, further stabilizing the installation position of the No. 2 mounting bolt 18.
[0016] The double-acting screw 4 is fixedly connected to the outer side of the worm wheel 5, and the mounting base 2 is rotatably connected to the worm 6. The worm 6 is meshed with the worm wheel 5. The rotation of the worm 6 drives the worm wheel 5 to rotate, thereby completing the rotation adjustment of the double-acting screw 4 inside the worm wheel 5.
[0017] Among them, a hexagonal rotating block 7 is rotatably connected to one side of the mounting base 2, and one end of the worm 6 is fixedly connected to the hexagonal rotating block 7. The worm 6 is rotated and adjusted by the hexagonal rotating block 7. When the worm 6 is rotated, the meshing worm wheel 5 is rotated, thereby driving the bidirectional lead screw 4 inside the worm wheel 5 to rotate and adjust.
[0018] The sliding inner plate 11 has a first limiting slider 13 fixedly connected to both sides. The clamping box 10 has a first limiting groove symmetrically opened inside to cooperate with the first limiting slider 13. The first limiting slider 13 is slidably connected to the first limiting groove. When the height position of the sliding inner plate 11 is adjusted in the clamping box 10, the sliding inner plate 11 drives the first limiting slider 13 to slide within the first limiting groove in the clamping box 10, which limits the adjustment position of the sliding inner plate 11 and improves the stability of the adjustment.
[0019] The bottom of the adjusting slide plate 8 is fixedly connected to a second limiting slider 22. The interior of the mounting base 2 is symmetrically provided with a second limiting groove that cooperates with the second limiting slider 22. The second limiting slider 22 is slidably connected to the second limiting groove. When the position of the adjusting slide plate 8 is adjusted in the mounting base 2, the second limiting slider 22 at the bottom is driven by the adjusting slide plate 8 to slide within the second limiting groove in the mounting base 2, thereby improving the stability of the adjusting slide plate 8.
[0020] Specifically, during use, when the I-shaped horizontal steel 3 is installed on the mounting base 2, the worm gear 6 is rotated and adjusted by the hexagonal rotating block 7. When the worm gear 6 rotates, it drives the meshing worm wheel 5 to rotate. When the worm wheel 5 rotates, it drives the inner double-acting screw 4 to rotate. When the double-acting screw 4 rotates, it drives the outer adjusting slide plate 8 to move and adjust. The movement of the adjusting slide plate 8 drives the top clamping box 10, sliding inner plate 11, fixed top plate 12, limiting slide plate 14, sliding plate 15, and mounting plate 16 to move. The clamping box 10 clamps and limits the outer side of the I-shaped horizontal steel 3. According to the adjusted position of the adjusting slide plate 8 and the mounting threaded hole 20, the opening 23 that mates with the mounting threaded hole 20, the mounting through hole 19, and the No. 2 mounting bolt 18 is drilled in the fixed side plate 9 using drilling equipment. Then the No. 2 mounting bolt 18 enters the fixed top plate 12 and the sliding inner plate 11. The second mounting bolt 18 is rotated into the mounting through hole 19 of the moving inner plate 11 and the clamping box 10. The second mounting bolt 18 is threaded into the mounting thread hole 20. The second mounting bolt 18 moves downward through the opening 23. The top nut of the second mounting bolt 18 is pressed against the top of the fixed top plate 12, pressing and fixing the fixed top plate 12 and the I-shaped horizontal steel 3. Then, the limit nut 21 is threaded on the outside of the second mounting bolt 18. The top of the limit nut 21 presses against the bottom of the fixed side plate 9, further stabilizing the installation position of the second mounting bolt 18. By pulling the mounting plate 16, the sliding plate 15 and the limit slide plate 14, one side of the mounting plate 16 is brought into contact with the I-shaped horizontal steel 3. The mounting plate 16 and the I-shaped horizontal steel 3 are fixed together by the first mounting bolt 17, fixing the I-shaped horizontal steel 3 at the top of the mounting base 2.
