The base plate fixing part (1221) fits against the base plate (11). Fasteners (8) pass through the base plate fixing part (1221), the base plate (11) and the first support member (61), so that the base plate fixing part (1221) and the base plate (11) fit together. The side plate fixing part (1222) is fastened to the first support member (61), and the side plate fixing part (1222) is located on both sides of the first side plate (121). The side plate fixing part (1222) and the end face of the second side plate (122) facing the first side plate (121) are fitted together. The fastener (8) passes through the side plate fixing part (1222) and the second side plate (122) to fasten the first side plate (121) and the second side plate (122). The first side plate (121) and / or the second side plate (122) are provided with the clearance hole (7).

7. The concrete column reinforcement device according to claim 6, characterized in that, The first support member (61) is provided with a second position adjustment structure, which cooperates with the first side plate (121) to adjust the distance between the pair of first side plates (121).

8. The concrete column reinforcement device according to claim 7, characterized in that, The second position adjustment structure includes a plurality of second waist-shaped holes (611), which are spaced apart along the guide direction of the first support member (61). The base plate fixing part (1221) is fixedly connected to any of the second waist-shaped holes (611) by fasteners (8).

9. The concrete column reinforcement device according to any one of claims 1 to 8, characterized in that, It also includes an adjusting positioning rod (9), which is set in the pouring cavity (3). One end of the adjusting positioning rod (9) is fixedly connected to the inner wall of the template (1), and the other end of the adjusting positioning rod (9) has a flexible structure (91) that abuts against the concrete column (2).

10. A method for reinforcing concrete columns, using the concrete column reinforcement device described in any one of claims 1 to 9, characterized in that, Includes the following steps: Remove the floor slab (4) around the concrete column (2) to reserve space for reinforcement. Roughen the surface of the concrete column (2) to be reinforced and the concrete beam connected to it. Then, install and tie the reinforcing bars of the concrete column (2) according to the construction process. Install template (1) and support components (6). For the reinforcement of floor slab (4), use vertical lifting equipment to hoist and lift template (1) through the chiseled floor slab (4) opening until the template (1) is hoisted to the reinforcement elevation position, ensuring that the bottom top elevation of template (1) is flush with the bottom elevation of the reinforcement node. Position the template (1) to ensure that the size of the pouring cavity (3) is the size of the concrete that needs to be reinforced; Clean the mold surface and use flexible sealing material to seal the gaps between the template (1) and the concrete column (2) and between the template (1) and the concrete beam; Pour concrete and vibrate it to make it compact. After the concrete reaches the demolding strength, remove the formwork (1) and support components (6).
