The connecting piece is two fixedly connected connecting angles 14, and the two connecting angles 14 are T-shaped structures. The transverse sections of the T-shaped structure are fixedly connected to the supporting member and the locking member respectively. Designing the connecting piece into a T-shaped structure can make the hanger more secure.

[0036] The supporting member includes an open base plate, a fixing frame and a fine-adjusting member. The open base plate is an open steel plate 1, and a plurality of openings are arranged on the open steel plate 1. The fixing frame is a fixed channel steel 2, and the fixed channel steel 2 is welded on the open steel plate 1. A matching nut 6 is fixed on the fixed channel steel 2. There are multiple groups of fine-adjusting members, and each group of fine-adjusting members includes a horizontal adjustment member, a vertical adjustment member and a top supporting plate. The vertical adjustment member is a tension spring 10, and the top supporting plate is a top supporting steel plate 9. The horizontal adjustment member includes a horizontal adjustment rod and a pushing member 8. The horizontal adjustment member adopts an adjustment structure of a single screw. Specifically, the horizontal adjustment rod adopts a fine-adjusting screw 5, and the fine-adjusting screw 5 is connected to the fixed channel steel 2 through a matching nut 6. The matching nut 6 is a pushing fulcrum for the rotation of the fine-adjusting screw 5. The front end of the adjusting screw 5 is movably connected with the push nut 7 fixed on the pushing member 8. The front end of the fine-adjusting screw 5 has a T-shaped structure, and the T-shaped structure is located between the push nut 7 and the pushing member 8. The T-shaped structure at the front end of the fine-adjusting screw 5 can ensure that the pushing member 8 is pushed or the pushing member 8 is pulled back by the push nut 7. The pushing member 8 slides horizontally on the open steel plate 1, and the open steel plate 1 can better support the pushing member 8 and ensure the horizontal fine adjustment of the steel bar 3. The pushing member 8 is connected to the supporting steel plate 9 through a tension spring 10. The supporting steel plate 9 is provided with a groove for placing steel bars. The vertical position of the steel bar 3 is adjusted by the tension spring 10, which can ensure the vertical fine adjustment of the steel bar 3 and make the steel bar connection more efficient and simple.

[0037] The locking component includes an upper open locking piece 11 and a lower open locking piece 12, and the upper open locking piece 11 and the lower open locking piece 12 are connected by a pin 13. The openings of the upper open locking piece 11 and the lower open locking piece 12 cooperate with each other to form an embracing structure, and the embracing structure can lock the steel bar 3 to prevent the steel bar 3 from falling off or shaking during lifting. The lower open locking piece 12 includes a fixedly connected steel plate and an angle steel, and a slide groove is formed between the steel plate and the angle steel. The upper open locking piece 11 includes a fixedly connected steel plate and a square steel, and the square steel is slidably placed in the slide groove. The steel plates of the upper open locking piece and the lower open locking piece are connected by a pin 13, and the lower open locking piece 12 is fixed to the connecting angle steel 14 through the angle steel.

[0040] (2) Position adjustment: During installation, a crane is used to lift the hanger and the steel bar 3 as a whole. The steel bar 3 moves downward by its own weight, and at the same time, the tension spring 10 is stretched, and the sleeve 4 is pressed against the top supporting steel plate 9 (such as Figure 3 As shown in the figure, the open steel plate 1 of the hanger is placed on the scaffold support point by using a rope-assisted crane, and the position of the steel bar 3 is roughly adjusted. After the hanger is stable, the pin 13 in the locking member is pulled out, and then the upper opening locking piece 11 is pushed laterally to disengage (as shown in the figure). Figure 5 As shown in the figure), by rotating the fine adjustment screw 5 to link the push member 8 to move forward or by pulling the push member 8 back through the push nut 7, the steel bar 3 is adjusted in the horizontal direction (as shown in the figure). Figure 4 As shown), lightly lift the steel bar 3, the steel bar 3 is contracted and moved upward by the tension spring 10, and the steel bar 3 is driven to adjust to the mechanical connection position in the vertical direction;

[0041] (3) Removal of the hanger: After the connection of the steel bar 3 is completed, a crane is used to separate the hanger from the steel bar 3, and the removal of the hanger is completed.

[0042] The steel bar overall fine-tuning installation hanger of the present invention can better support the fine-tuning components through the open steel plate to ensure the horizontal fine-tuning of the steel bar; the T-shaped structure at the front end of the fine-tuning screw pushes and pulls back the pushing components to accurately adjust the horizontal position of the steel bar, and the tension spring adjusts the vertical position of the steel bar to ensure the vertical adjustment accuracy of the steel bar, which is more flexible and improves the efficiency of steel bar installation; the two layers of open locking pieces are used to pull and encircle the steel bar and disassemble the hanger, which is flexible to install and disassemble, easy to operate, and can effectively prevent the steel bar from falling off and shaking during the lifting process, which is safer and more reliable. The hanger is suitable for the fine-tuning connection of steel bars with variable curvature sections and slope structures. Different types of hangers can be made according to different types of steel bars to adapt to the overall fine-tuning installation of steel bars of different sizes and spacings.

[0043] The application of the steel bar integral fine-tuning installation hanger of the present invention is suitable for large-scale steel bar integral fine-tuning installation operations, which greatly reduces the use time of the crane, greatly improves the construction operation efficiency, reduces the demand for manpower and material resources, and effectively reduces the construction cost.
