[0021] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-4 The present invention provides a technical solution: an auxiliary positioning device for the installation of a portal frame structure, comprising a first fixing plate 1, a fastening bolt 2 installed on the first fixing plate 1, an installation plate 3 rotatably connected to the first fixing plate 1 through the fastening bolt 2, a hollow rod 4 connected to the installation plate 3, a first threaded rod 5 rotatably connected inside the hollow rod 4, a rotating wheel 6 connected to one end of the first threaded rod 5, a movable rod 7 threadedly installed on the first threaded rod 5, and a guide groove 8 provided on the movable rod 7.

[0023] A sliding sleeve 9 is slidably connected to the movable rod 7. One end of the movable rod 7 is rotatably connected to a support plate 10 via a fastening bolt 2. A sliding groove 11 is provided on the support plate 10. A connecting plate 12 is connected below the support plate 10. A second threaded rod 13 is rotatably connected in the sliding groove 11. A torsion block 14 is connected to one end of the second threaded rod 13. Two clamping plates 15 are installed on the second threaded rod 13. Threaded sleeves 16 are installed on the clamping plates 15.

[0024] One side of the sliding sleeve 9 is rotatably connected to a telescopic rod 17 via a pin. One end of the telescopic rod 17 is connected to a second fixed plate 18. The sliding sleeve 9 is in close contact with the movable rod 7. The contact between the sliding sleeve 9 and the movable rod 7 can prevent the sliding sleeve 9 from rotating on the movable rod 7. The extension and retraction of the telescopic rod 17 can allow the sliding sleeve 9 to adapt to the movable rod 7 at different angles.

[0025] Nuts are threaded onto the fastening bolts 2 at one end of the first fixed plate 1 and the movable rod 7. The connecting plate 12 is rotatably connected to the fastening bolts 2 at one end of the movable rod 7. Fixing holes 19 are provided on both the first fixed plate 1 and the second fixed plate 18. By screwing threaded bolts into the fixing holes 19 on the first fixed plate 1 and the second fixed plate 18, the first fixed plate 1 and the second fixed plate 18 are fixed, so that the positioning device can support the steel frame beam. The angle between the hollow rod 4 and the support plate 10 can be adjusted by loosening and tightening the nuts on the fastening bolts 2.

[0026] The second threaded rod 13 has threads in opposite directions at both ends. The threaded sleeve 16 is threadedly engaged with the second threaded rod 13. The torsion block 14 has a hexagonal groove. Through the threads in opposite directions at both ends of the second threaded rod 13, the two clamping plates 15 can move in opposite directions to clamp the steel frame beam. The operation is simple and convenient, and the efficiency of connection and positioning is improved.

[0027] Guide blocks 20 are connected to the inner walls on both sides of the hollow rod 4. The guide blocks 20 slide in the guide groove 8. When the movable rod 7 moves, the guide blocks 20 will move in the guide groove 8. Thus, the movement of the movable rod 7 is guided and restricted by the cooperation between the guide blocks 20 and the guide groove 8, so as to prevent the movable rod 7 from rotating and deviating.

[0028] An anti-slip pad 21 is connected to the clamping plate 15. The anti-slip pad 21 is provided with anti-slip texture. When the clamping plate 15 comes into contact with the steel frame beam, the anti-slip pad 21 will be squeezed, thereby increasing the contact friction and improving the stability of the clamping.

[0029] In use, the worker first fixes the first fixing plate 1 to the steel frame column using the fixing hole 19 and threaded bolts. Then, the angle of the hollow rod 4 is adjusted by loosening and tightening the nuts on the fastening bolts 2. The first threaded rod 5 is then rotated by the rotating wheel 6, causing the movable rod 7 to move along the hollow rod 4, thereby adjusting the length of the positioning device and supporting different positions of the steel frame beam. Then, the torsion block 14 is turned by the Allen wrench, causing the second threaded rod 13 to rotate, thereby driving the two clamping plates 15 to move in opposite directions along the sliding groove 11 to clamp and position the steel frame beam. Then, the sliding sleeve 9 slides on the movable rod 7 and threaded bolts are screwed into the fixing hole 19 on the second fixing plate 18 to fix it to the steel frame column, so that the telescopic rod 17 and the movable rod 7 form a stable structure to support the portal frame.
