[0022] Reference Figure 1 and Figure 2 As shown, a large template hoisting device includes: a base steel plate 1, a U-shaped steel plate 3 disposed above the base steel plate 1, and a hoisting device 4 detachably connected to the U-shaped steel plate 3; the base steel plate 1 is rectangular, and a through hole is provided in the center of the base steel plate 1. The through hole has the same diameter as the opening of the template 5. A connecting bolt 2 is fitted inside the through hole and the opening of the template 5. The base steel plate 1 is connected to the template through the connecting bolt 2, and the end of the connecting bolt 2 is fitted with a connecting nut.

[0023] Preferably, in this embodiment, the lifting device 4 includes: a U-shaped steel bar and a limiting bolt detachably connected to the end of the U-shaped steel bar; both ends of the U-shaped steel bar are provided with connecting holes, the limiting bolt passes through the connecting holes in sequence, the end of the limiting bolt is sleeved with a limiting nut, and a detachable annular space is formed between the U-shaped steel bar and the limiting bolt, the annular space containing the U-shaped steel plate 3 and the steel wire rope.

[0024] Preferably, in this embodiment, a number of reinforcing ribs 7 are provided between the base steel plate 1 and the U-shaped steel plate 3.

[0025] When in use, the large formwork hoisting device is connected to the formwork 5 via connecting bolts 2, and the lifting device 4 is connected to the U-shaped steel plate 3. The wire rope is then passed through the lifting device 4 to meet the requirements for hoisting the large formwork 5. After hoisting is completed, simply remove the connecting bolts 2. This effectively solves problems such as formwork 5 deformation, wire rope breakage, and low construction efficiency during formwork 5 transportation. The hoisting device has low manufacturing cost and simple manufacturing method. After being put into use, it can greatly reduce labor input, and is safe, reliable, easy to operate, and has high construction efficiency, with good economic and safety features. Example 2

[0026] Based on Example 1, such as Figure 3 As shown, in this embodiment, the base steel plate 1 is a rectangular plate with several through holes. In this embodiment, there are three through holes. The distance between two adjacent through holes is the same as the distance between the openings of the template 5. A connecting bolt 2 is fitted in each through hole. The base steel plate 1 is connected to the template by the connecting bolt 2. The end of the connecting bolt 2 is fitted with a connecting nut.

[0027] It should be noted that, in this embodiment, increasing the number of through holes corresponds to increasing the length of the base steel plate 1, which can increase the contact area between the base steel plate 1 and the template 5, reduce the stress on the opening of the template 5, and prevent the sidewall of the template 5 from deforming.

[0028] Preferably, in this embodiment, a plurality of auxiliary steel plates 8 are provided on both sides of the base steel plate 1.
