The column hoops 2 can support and protect the column formwork 1, so that the situation that the column formwork 1 deforms and breaks due to the fact that the lateral pressure of concrete on the column formwork 1 is too large when the column formwork 1 is filled with concrete is reduced. The wood edges 12 are arranged, so that the pressure of the column hoop 2 on the forming plate 11 is more uniformly distributed on the surface of the forming plate 11.

As shown in fig. 2 and fig. 3, the column band 2 includes four clamping assemblies 13 surrounding each other, the clamping assemblies 13 include clamping arms 21 and sleeves 22, the side walls of the sleeves 22 are fixedly connected to the end faces of the clamping arms 21, so that the axial lines of the sleeves 22 are perpendicular to the length direction of the clamping arms 21, and the sleeves 22 can sleeve and slidably connect the clamping arms 21 in another clamping assembly 13. A rectangular slot 221 is formed in the side of the sleeve 22 facing away from the holding arm 21. An elastic sheet 3 is arranged in the strip hole 221, an L-shaped fixing sheet 31 is vertically and fixedly connected to one side wall of the elastic sheet 3, and the fixing sheet 31 is matched with the edge of the strip hole 221, so that the inner side wall of the elastic sheet 3 is flush with the inner side wall surface of the strip hole 221 opened on the sleeve 22. The fixing piece 31 and the elastic piece 3 are integrally formed. The fixing plate 31 is provided with two fixing bolts 32, and the fixing bolts 32 are screwed with the outer side wall of the sleeve 22, so that the elastic sheet 3 and the sleeve are fixed to each other.

As shown in fig. 3 and 4, when a clamping arm 21 is inserted into the sleeve 22, one surface of the elastic sheet 3 facing the clamping arm 21 is fixedly connected with a plurality of latch teeth 30, the latch teeth 30 are arranged in two rows, three latch teeth 30 are arranged in each row along the length direction of the elastic sheet 3, and a plurality of fixing teeth 211 matched with the latch teeth 30 are fixedly connected on the corresponding side wall of the clamping arm 21 matched with the latch teeth along the length direction of the clamping arm 21.

The arrangement of the rotating ball 35 converts the sliding friction between the end surface of the top contact bolt 34 and the surface of the clamping arm 21 into the rolling friction between the rotating ball 35 and the surface of the clamping arm 21, so that the sleeve 22 can be separated from the clamping arm 21 more easily.

As shown in fig. 5, since the knock bolt 34 is not a common component, and the knock bolt 34 is free outside the entire column band 2, it is inconvenient to store and easy to lose. Therefore, the top contact bolt 34 is further fixedly connected with a fixing rope 36, the other end of the fixing rope 36 is fixedly connected with the sleeve 22, and the top contact bolt 34 and the sleeve 22 are connected with each other through the fixing rope 36, so that the integrity of the column hoop 2 is improved, and the loss of the top contact bolt 34 can be reduced.

The working process is as follows: when the staff need establish the column hoop 2 to the cover in the concrete column template 1 outside, can link to each other and the cover is established in the periphery of concrete column template 1 with four add holding the subassembly head. The clamping arms 21 are inserted into the corresponding sleeves 22, and the column hoops 2 are tightened with each other, after the column hoops 2 are attached to the surface of the wood edges 12, the column hoops 2 can keep a fixed shape due to the mutual clamping of the fixing teeth 211 and the clamping teeth 30, and further a certain support is provided for the column formwork 1. When the staff need demolish the column hoop 2, can go into the top through bolt 34 in the screw hole 33 on shell fragment 3 soon, push away the surface that the shell fragment 3 kept away from centre gripping arm 21 through the top through bolt 34 that touches, and then make latch 30 and fixed tooth 211 break away from, sleeve 22 and the centre gripping arm 21 alternate segregation that inserts in sleeve 22 to the dismantlement of column hoop 2 has been accomplished.
