[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely explain the technical solutions in the embodiments of the utility model. It should be noted that the embodiments and features in the embodiments of the utility model can be combined with each other without conflict, and the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0025] See also Figure 1-5 To illustrate the present embodiment, an integrally lifting rectangular shaft formwork comprises an integral formwork 1, a ladder 3, a driving structure and a supporting structure, wherein the multiple supporting structures are arranged on the inner wall of the integral formwork 1, the ladder 3 and the driving structure are both arranged on one side of the inner wall of the integral formwork 1, and the driving structure is connected to the ladder 3, and the ladder 3 is driven to rise by the driving structure.

[0026] When the construction workers go down into the integrated formwork through the provided ladder and finish their work, they climb out of the integrated formwork 1 along the ladder. After pouring the vertical shaft, they open the driving structure and drive the ladder 3 to rise through the driving structure, which not only allows the ladder 3 to be removed from the integrated formwork 1, but also reduces the overall load of the integrated formwork 1, making it easier to demould later.

[0027] The supporting structure includes a plurality of cross frames 14, a plurality of vertical beams 15 and a supporting unit. The cross frames 14 are arranged at equal intervals on the inner wall of the integrated formwork 1 in the horizontal direction. The vertical beams 15 are evenly distributed on the inner wall of the integrated formwork 1 in the vertical direction. The cross frames 14 and the vertical beams 15 are fixedly connected at the intersection. The supporting unit is arranged between the cross frames 14 and the vertical beams 15. The supporting structure ensures that the integrated formwork 1 reduces deformation caused by pouring.

[0028] A plurality of screw holes 10 are provided at equal intervals in the cross frame 14, and the support unit comprises reinforcing steel bars 6, fixed angle steels 7, fixed sleeves 8 and locking bolts 9. The upper end of the reinforcing steel bars 6 is connected to the cross frame 14 through the cooperation of the fixed sleeves 8, the locking bolts 9 and the screw holes 10. The fixed sleeves 8 are arranged on the outside of the cross frame 14, and are connected to the cross frame 14 through the locking bolts 9 and the screw holes 10. The upper end of the reinforcing steel bars 6 is hinged to the fixed sleeves 8, and the fixed angle steels 7 are arranged on the vertical beams 15. The fixed angle steels 7 are connected to the bottom ends of the reinforcing steel bars 6. The reinforcing steel bars 6 can be adjusted in position through the fixed sleeves 8 so as to be suitable for integrated formworks 1 of different specifications, thereby saving a great deal of cost for the construction unit.

[0029] The reinforcing steel bars 6 are grouped together in two pieces, and the reinforcing steel bars 6 and the cross frame 14 form a triangular support structure. The triangular support structure improves the supporting force of the inner wall of the integrated formwork 1, reduces the deformation of the integrated formwork 1 caused by pouring, ensures the regular shape of the shaft, and extends the service life of the formwork.

[0030] Artificial racks 5 are arranged on both sides of the ladder 3 , and the artificial racks 5 are connected to the driving structure, so that the ladder 3 is driven to rise through the artificial racks 5 .

[0031] The driving structure includes two groups of gears 2 and a driving motor 16. The driving motor 16 is arranged in one of the groups of gears 2. The two groups of gears 2 are meshed and connected with the artificial rack 5. After the driving motor 16 is energized, the two groups of gears 2 are driven to rotate by the driving motor 16. The two groups of gears 2 are meshed with the artificial rack 5, driving the ladder to rise, so that the ladder is removed from the integrated formwork 1, thereby reducing the overall load of the integrated formwork 1.

[0032] A limit plate is installed on the top of the ladder 3, and the bottom of the ladder 3 is abutted against the bottom of the integrated formwork 1. The ladder 3 ensures that construction workers can work safely up and down in the shaft. The limit plate can ensure that the formwork is connected as a whole and has enough space for activities.

[0033] A welding foot 13 is provided at the intersection of the cross frame 14 and the vertical beam 15 , and the stability of the connection between the cross frame 14 and the vertical beam 15 is reinforced by providing the welding foot 13 .

[0034] A fixed step 12 is arranged on the lower half of the inner wall of the integrated formwork 1, and the fixed step 12 surrounds the inner wall. A plurality of hydraulic cylinders 11 are arranged on the bottom of the integrated formwork 1, and the piston rods of the hydraulic cylinders 11 are upwardly abutted against the fixed step 12. A corresponding number of hydraulic cylinders 11 can be arranged according to the weight of the integrated formwork 1. The hydraulic cylinders 11 are regularly distributed on the bottom of the integrated formwork 1, and are used to push the integrated formwork 1 in the later stage, cooperate with external cranes and other equipment, so as to better realize demoulding and reduce the risk of construction accidents caused by demoulding.

[0035] The outer wall of the integrated formwork 1 is covered with an outer wall plate 4, which is an integrally bent metal plate without welds. The outer wall plate 4 ensures that the surface of the shaft is smooth, which is convenient for construction after casting.

[0036] When the utility model is in use, first, the integrated formwork 1 is hoisted into the well by a crane, and then the outer wall is poured. After the poured concrete is waited for solidification, after the pouring is completed, the construction personnel go down to the integrated formwork 1 to work. After the work is completed, they can climb out of the formwork along the ladder 3, and then connect the power to the drive motor 16, drive the gear 2 to rotate through the drive motor 16, and the two sets of gears 2 are meshed with the artificial rack 5 to drive the ladder 3 to rise, so that the ladder 3 is removed from the integrated formwork 1. A plurality of hydraulic cylinders 11 are pre-placed at the bottom of the integrated formwork 1. The number of hydraulic cylinders 11 can be set according to the weight of the integrated formwork 1, and the hydraulic pressure is used later. The piston rod of the cylinder pushes the fixed step 12 in the integrated formwork 1 to lift the integrated formwork 1 upward, and cooperates with external cranes and other equipment to better realize demoulding. In the integrated formwork 1, reinforcing ribs 6 are set up through cross frames 14 and vertical beams 15 to prevent the integrated formwork 1 from being easily deformed due to pouring. The bottom end of the reinforcing steel bar 6 is connected to the vertical beam 15 through a fixed angle steel 7, and the upper end of the reinforcing steel bar 6 can be adjusted in position through a fixing sleeve 8, a locking bolt 9 and a screw hole 10 on the cross frame 14 so as to be suitable for integrated formworks 1 of different specifications. The reinforcing ribs 6 that constitute a triangular structure can increase the supporting force of the inner wall and reduce the deformation of the formwork caused by pouring.
