DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0027] Embodiment 1:

[0028] like Figure 1-Figure 8As shown, a hoop formwork for cast-in-place construction of piers comprises two formwork units 101, the cross section of the formwork unit 101 is semicircular, a plurality of first reinforcing ribs 104 and third reinforcing ribs 106 are arranged on the formwork unit 101, a plurality of bolt through holes 107 are arranged on the third reinforcing ribs 106 on the two formwork units 101, and the two formwork units 101 are surrounded into a full circle to form a complete hoop formwork by passing bolts through the third reinforcing ribs 106 on the two formwork units 101; an anti-scratch component is arranged on the formwork unit 101, and the anti-scratch component comprises a mounting frame 103, two swing arms 109 are rotatably connected to the mounting frame 103, and the two swing arms 109 are respectively arranged at two ends of the axial direction of the formwork unit 101, and an anti-scratch wheel 108 is arranged on the swing arm 109, which is pressed against the surface of the pier by the plurality of anti-scratch wheels 108, so that the distance from the circumferential surface of the formwork unit 101 to the pier is always the same, so as to prevent the formwork unit 101 from scratching the pier when the formwork is disassembled.

[0029] After the two template units 101 are combined with bolts, the casting of the pier begins. When the pier is finalized, the two template units 101 are slightly separated so that the template unit 101 is separated from the pier. At this time, the anti-scratch wheels 108 are pressed on the surface of the pier. Although the two anti-scratch wheels 108 have been separated from the pier, the two template units 101 are still connected together by bolts. Under the action of multiple anti-scratch wheels 108, the two template units 101 will not touch the pier. Then the template can be lifted and pulled out of the pier. The above arrangement solves the problem of the inconvenience of template removal when casting piers in a narrow space in the prior art, and achieves the technical effect of smoothly removing the template without damaging the pier after the casting of the pier is completed in a limited space.

[0030] Embodiment 2:

[0031] like Figure 4-Figure 5 As shown, the mounting frame 103 is provided with a plurality of adjustment limit grooves 112, the adjustment limit grooves 112 are fixedly connected with springs 113, the springs 113 are fixedly connected with pressure blocks 114, the elastic force of the springs 113 pushes the limit pin 110 through the pressure blocks 114, so that the limit pin 110 pushes the anti-scratch wheel 108 on the swing arm 109 to be close to the pier column. When the two template units 101 are slightly separated, the anti-scratch wheel 108 can be close to the pier column under the action of the spring 113, and when the two template units 101 are combined, the spring 113 is further compressed, and the anti-scratch wheel 108 is still close to the pier column. Through the above arrangement, the plurality of anti-scratch wheels 108 can always complete the positioning function, ensuring that the distance from the circumferential surface of the template unit 101 to the pier column is always the same, and ensuring that the template unit 101 will not damage the pier column.

[0032] like Figure 4-Figure 5As shown, the mounting frame 103 is provided with a plurality of stowage limiting holes 111. When the anti-scratch wheel 108 needs to be stowed, the stowage limiting hole 111 is used to insert the stowage limiting hole 111, thereby limiting the swing arm 109. Through the above arrangement, after the anti-scratch wheel 108 and the swing arm 109 are stowed, the limiting latch 110 can be stuck in the stowage limiting hole 111 to limit the swing arm 109, thereby preventing the anti-scratch wheel 108 from shaking, and facilitating construction.

[0033] like Figure 5 As shown, a rubber layer is provided on the circumferential surface of the anti-scratch wheel 108. Through the above arrangement, it can be further ensured that the anti-scratch wheel 108 will not damage the pier column.

[0034] like Figure 4 As shown, the template unit 101 is fixedly connected with a plurality of lifting ears 102, and a reinforcing rib is arranged between the lifting ears 102 and the template unit 101. The plurality of lifting ears 102 are evenly distributed, and the above arrangement can facilitate the template to be lifted off the pier, thereby improving the working efficiency.

[0035] like Figure 6 As shown, a plurality of the first reinforcing ribs 104 are provided with second reinforcing ribs 105, and a splitting assisting assembly is provided between two template units 101. The splitting assisting assembly can speed up the splitting operation of the template units 101 and improve the operation efficiency.

[0036] like Figure 6-Figure 7 As shown, the split assist assembly includes two symmetrically arranged outward expansion plates 116 and two connecting columns 119, and the outward expansion plates 116 are rotatably connected to multiple first connecting rods 117 and second connecting rods 118. The two connecting columns 119 are rotatably connected to the first connecting rod 117 and the second connecting rod 118 on the same side, respectively. A threaded hole is provided on the connecting column 119, and two sections of threads with opposite rotation directions are provided on the driving screw 120. The driving screw 120 is threadedly connected to the two connecting columns 119, and the connecting columns 119 are respectively matched with different threads. The driving screw 120 is fixedly connected to the sleeve 121. When the two template units 101 need to be separated, the bolts fastening the two template units 101 are first loosened, and then the split assist assembly is placed between the two template units 101. The driving screw 120 is rotated by the person twisting the sleeve 121. When the driving screw 120 rotates, the two connecting columns 119 approach each other, so that the first connecting rod 117 and the second connecting rod 118 push the two outer expansion plates 116 away from each other, and the outer expansion plates 116 push the third reinforcing ribs 106, so that the two template units 101 are away from each other, and the template unit 101 is separated from the pier column and the two template units 101 are separated. Through the above arrangement, the labor intensity of personnel can be reduced and the work efficiency can be improved.

[0037] like Figure 8As shown, the template unit 101 is provided with a curling edge 115, and the center of the curling edge 115 is located outside the circumferential surface of the template unit 101. The radius of the connection between the curling edge 115 and the template unit 101 is R, and by setting the outer curling of the curling edge 115, when the template unit 101 is lifted off the pier, even if the template unit 101 touches the pier, it will not damage the pier.

[0038] Working principle: In the initial state, all swing arms 109 are retracted, and the swing arms 109 are limited by inserting the limit pin 110 into the retracted limit hole 111 to facilitate the subsequent pouring of the pier column. Then, the personnel use the bolts to insert through the bolt holes 107 to fasten and combine the two template units 101, and then the pouring of the pier column can begin. When the pier column is completely finalized, loosen the bolts inserted in the bolt holes 107, but do not completely remove the bolts, so that the two template units 101 are still connected together by bolts; put the split assist assembly between the two template units 101, and then use it to separate the two template units 101 from the pier column, and then take out the limit The limit pin 110 is positioned to move the swing arm 109 to the working state, and then the limit pin 110 is inserted into the adjustment limit slot 112, and the elastic force of the spring 113 is used to make the limit pin 110 press the swing arm 109 tightly. At this time, the anti-scratch wheel 108 is pressed on the surface of the pier, and the anti-scratch wheel 108 is used to adjust the positions of the two template units 101, so that the distance from each position of the circumferential surface of the template unit 101 to the pier is the same, and then the rope of the hoist is put on the lifting ear 102 to lift the template as a whole. In this process, due to the action of the anti-scratch wheel 108 and the spring 113, the template unit 101 will never touch the pier until the template is completely lifted off the pier.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
