[0028] Specific implementation method in this embodiment: when it is necessary to reinforce the formwork body 1 completed by the formwork on both sides of the cast-in-place shear wall, a clamping plate 5 is horizontally fixed to the lower part of the side of the formwork body 1 by nails penetrating the positioning holes 7 on the fixing plate 6, and a number of square timbers 2 are inserted into the clamping plate 5, and the positions of the square timbers 2 are limited by nails penetrating the clamping plate 5 and nailing them on the square timbers 2. The nails do not need to be completely nailed into the square timbers 2, so that the clamping plate 5 can be removed when the formwork is removed later. After all the required square timbers 2 are placed in the clamping plate 5, the upper part of the square timbers 2 is limited and fixed again by the fixing plate 6 and the clamping plate 5 in the above-mentioned manner. The through-wall bolts 3 penetrate the two formwork bodies 1, and several of the through-wall bolts 3 are horizontal. Two adjacent reinforcement rods 4 are located above and below the several horizontal through-wall bolts 3, and the reinforcement rods 4 symmetrically arranged on both sides of the two formwork bodies 1 are locked by the locking unit to complete the reinforcement of the formwork body 1. Several positioning holes 7 are opened on the clamping plate 5 and the fixing plate 6, and the square wood 2 is positioned with nails used on site to prevent the square wood 2 from tipping over when pouring concrete in the formwork body 1. The overall structure is simple and suitable for different types of square wood 2, thereby reducing the cost of reinforcing the shear wall formwork body 1.

[0029] Embodiment 2

[0030] See also Figure 1-Figure 4 , this embodiment includes the above-mentioned embodiment, wherein the locking unit includes a U-shaped clamping frame 8 sleeved on both ends of the through-wall bolt 3, the clamping frame 8 is adapted to the two adjacent reinforcement rods 4 and clamped on the sides of the two adjacent reinforcement rods 4, both ends of the through-wall bolt 3 are threadedly connected with a limit nut 9, and the side of the limit nut 9 is fixedly connected with a reinforcing circular plate 10, the reinforcing circular plate 10 is adapted to the clamping frame 8, and each side of the clamping frame 8 is fixedly connected with an L-shaped fixing frame 13, and the fixing frame 13 is penetrated by a movable column 1 4. A plurality of tooth grooves 16 are provided on the side of the reinforcing circular plate 10. A limit plate 15 adapted to the tooth groove 16 is fixedly connected to one end of the moving column 14. A spring 17 sleeved on the side of the moving column 14 is provided between the fixing frame 13 and the limit plate 15. A transverse plate 19 which is perpendicular to the moving column 14 is fixedly connected to one end of the moving column 14 away from the limit plate 15. A lifting bolt 18 is threadedly connected to the transverse plate 19. The end of the lifting bolt 18 can be abutted against the side of the fixing frame 13. The cross section of the moving column 14 is rectangular.

[0031] Specific implementation method of this embodiment: when it is necessary to reinforce the reinforcement rod 4, the clamping frame 8 is sleeved on the side surfaces of the two ends of the through-wall bolt 3, and the clamping frame 8 is clamped on the side surfaces of two adjacent reinforcement rods 4 to limit the positions of the two adjacent reinforcement rods 4. The limiting nuts 9 are threadedly connected to the two ends of the through-wall bolt 3, and the two limiting nuts 9 are locked by an electric wrench to lock the reinforcement rod 4. The reinforcing circular plate 10 increases the contact area between the limiting nuts 9 and the clamping frame 8 to improve the reinforcement effect. After the limiting nuts 9 are locked, the lifting bolt 18 is rotated by the electric wrench. When the lifting bolt 18 rotates, the limiting plate 15 is pushed downward due to the tension of the spring 17 and the action of the moving column 14. The moving column 14 with a rectangular cross-section limits the position of the limiting plate 15 and prevents the spring 17 from When radial deformation occurs, one side of the limit plate 15 engages with the tooth groove 16, thereby limiting the position of the reinforcing circular plate 10. The lifting bolt 18 is continuously rotated so that one end of the lifting bolt 18 is disengaged from the fixing frame 13, thereby ensuring that the tension of the spring 17 is fully applied to the limit plate 15, thereby preventing the limit nut 9 from loosening when pouring concrete and vibrating concrete in the formwork body 1, thereby improving the reinforcement effect of the formwork body 1. When the locking unit needs to be disassembled, the lifting bolt 18 is rotated in the opposite direction with an electric wrench, so that one end of the lifting bolt 18 is against the side of the fixing frame 13, and the lifting bolt 18 is continuously rotated to drive the movable column 14 to move upward, thereby driving the limit plate 15 away from the reinforcing circular plate 10, and the limit nut 9 can be removed with an electric wrench. The structure is simple and the operation is convenient.

[0034] The specific implementation method in this embodiment: when connecting the clamping plate 5 with the template body 1, the clamping plate 5 is fixed according to the position where the through-wall bolt 3 needs to be inserted. When the square wood 2 is installed, the reinforcement rod 4 is plugged into the plug-in frame 11 through the plug-in block 12 to pre-fix the reinforcement rod 4. When the reinforcement personnel operate the limit nut 9, there is no need to support the reinforcement rod 4, which is convenient for the reinforcement personnel to reinforce the template body 1 and reduces the labor intensity of the reinforcement personnel.
