Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figure 1. In this embodiment, the steel waist beam and prestressed anchor reinforcement device includes a steel waist beam 1. A mounting plate 2 is fixedly installed on the top of the steel waist beam 1. Two expansion nails 3 are fixed to the steel waist beam 1 and are slidably connected inside the mounting plate 2. The expansion nails 3 are used to fix the whole to the steel waist beam 1. A connecting block 4 is fixed on the top of the mounting plate 2. Two positioning plates 5 are fixed on the top of the connecting block 4. The two positioning plates 5 are internally rotatably connected with an angle adjustment component 6.

In addition, a connecting block 7 located between the two positioning plates 5 is fixed to the outer surface of the angle adjustment component 6, and a support frame 8 is fixed to the top of the connecting block 7. The angle adjustment component 6 is used to adjust the angle between the mounting plate 2 and the support frame 8. A fixing component 9 is arranged inside the support frame 8. The fixing component 9 includes a moving rod 901, a control block 902 and two fixing blocks 903. The moving rod 901 is threadedly connected to the support frame 8, the left side of the moving rod 901 is fixed to the control block 902, the right side of the moving rod 901 is rotatably connected to one of the fixing blocks 903, and the right side wall of the inner cavity of the support frame 8 is fixed to the other fixing block 903. The prestressed anchor rod can be effectively clamped and fixed by the set fixing block 903. The fixing component 9 is used to fix the prestressed anchor rod.

In general, by rotating the movable rod 901, the movable rod 901 can be moved simultaneously due to the extrusion of the thread, thereby shortening the distance between the two fixed blocks 903, and then the prestressed anchor rod can be effectively fixed. The overall structure is simple and the overall practicality is effectively improved.

Please refer to Figures 2-3. In order to facilitate the overall adjustment, the angle adjustment assembly 6 in this embodiment includes a rotating rod 601, two limit blocks 602, a limit assembly and four telescopic rods 603. The rotating rod 601 is rotatably connected to the positioning plate 5, the outer surface of the rotating rod 601 is fixed to the connecting block 7, the outer surface of the rotating rod 601 is threadedly connected to the limit block 602, the interior of the limit block 602 is fixed to the telescopic rod 603, the telescopic rod 603 includes an extension block fixed to the limit block 602, the interior of the extension block is slidably connected to the extension block fixed to the limit plate 604, and the telescopic rod 603 is set so that after the limit block 602 moves, the limit plate 604 can still limit the rotation of the limit block 602.

In addition, the outer surface of the telescopic rod 603 is fixed to the limit assembly, and the limit assembly is used to limit the rotation of the rotating rod 601. The limit assembly includes two pushing rods 605, a handle 606 and a limit plate 604. The limit plate 604 is slidably connected to the rotating rod 601, and the limit plate 604 is fixed to the telescopic rod 603. The limit plate 604 penetrates into the interior of the connecting block 4, and the interior of the limit plate 604 is threadedly connected to the pushing rod 605. The pushing rod 605 is a threaded rod, and the interior of the limit plate 604 is provided with a threaded hole that is compatible with the threaded rod. Through the threaded connection, the rotation of the pushing rod 605 will push the non-rotatable limit plate 604 to move. The inner cavity of the connecting block 4 is fixed with a fixed bearing, and the interior of the fixed bearing is fixed to the pushing rod 605. By setting the fixed bearing, the stability of the rotation of the pushing rod 605 can be effectively improved, thereby making the overall operation more stable.

The outer surface of the handle 606 is fixed with a friction strip, and the outer surface of the rotating rod 601 is fixed with a positioning block 607. The positioning block 607 is used to prevent the rotating rod 601 from being displaced. The friction strip can effectively improve the comfort of rotating the handle 606. The opposite sides of the two handles 606 are fixed with a plug-in block. The interior of the push rod 605 is provided with a plug-in groove matched with the plug-in block. The handle 606 can normally drive the push rod 605 to rotate by plugging the plug-in block into the plug-in groove. The limit plate 604 is inserted into the interior of the connecting block 4, so that the connecting block 4 can effectively limit the rotation of the limit plate 604. The handle 606 is connected by plugging, which makes it easy to disassemble later, effectively improving the overall practicality.

In general, when the rotating rod 601 rotates, it will push the limit block 602 to move, and the set limit plate 604 can effectively limit the movement of the limit block 602, thereby simply and effectively realizing the restriction of the rotation of the rotating rod 601. The overall structure is simple and effectively improves the overall practicality.

The working principle of the above embodiment is:

After the mounting plate 2 is fixed to the steel waist beam 1, if it is found that the overall angle with the prestressed anchor rod is incorrect, the push rod 605 is driven to rotate by rotating the handle 606, so that the limit plate 604 that cannot rotate is moved due to the extrusion of the thread, and then the limit plate 604 is away from the limit block 602. At this time, the angle adjustment can be completed by rotating the rotating rod 601, and when the rotating rod 601 is rotated, the limit block 602 that cannot rotate is moved due to the extrusion of the thread. When the adjustment is completed and needs to be re-fixed, the limit plate 604 is pushed to fit the limit block 602 again by rotating the handle 606. Because the limit block 602 is pushed to move when the rotating rod 601 rotates, the limit plate 604 can limit the movement of the limit block 602, thereby effectively completing the adjusted fixation. The overall structure is simple, the angle adjustment is more accurate, and the overall practicality is effectively improved.
