[0017] To make the technical problems, technical solutions, and beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 and 2 As shown in the figure, this embodiment discloses a modular arc-shaped wall template reinforcement device that can be reused, including a steel template 1, a longitudinal keel 6, a transverse keel 3, and a sleeve 7.

[0019] An elastic sealing element 2 is provided between two adjacent steel templates 1 on the left and right. The two adjacent steel templates 1 can be bent at the elastic sealing element 2. A longitudinal keel 6 is provided on the outside of each steel template 1. The longitudinal keel 6 is arranged longitudinally and abuts against the outer wall of the steel template 1.

[0020] The transverse keel 3 is arranged perpendicularly to the longitudinal keel 6. The transverse keel 3 abuts against the longitudinal keel 6. The transverse keel 3 includes several transverse connecting members 301 arranged in sequence. Adjacent transverse connecting members 301 are connected by a hinge locking device 302.

[0021] Each steel template 1 is provided with multiple sleeves 7. The end of the sleeve 7 abuts against the inner wall of the steel template 1. The end of the sleeve 7 with the tie rod 4 passes through the steel template 1, the longitudinal keel 6, and the transverse connector 301 and is connected to the first nut 5. The first nut 5 presses against the transverse keel 3.

[0022] like Figure 3 and 4As shown, in this embodiment, the hinge locking device 302 includes a cylindrical shaft 302-1, with inner ear plates 302-2 fixed at both ends of the cylindrical shaft 302-1. The two inner ear plates 302-2 are fixed to a horizontal connecting member 301 on one side. A central shaft 302-3 is rotatably connected in the cylindrical shaft 302-1. The two ends of the central shaft 302-3 pass through the inner ear plates 302-2 and are fixed to the outer ear plates 302-4. The two outer ear plates 302-4 are fixed to the horizontal connecting member 301 on the other side.

[0023] The inner ear plate 302-2 and the outer ear plate 302-4 are fixed by a locking structure, which includes a spring 302-5, a pressure plate 302-6, a locking pin 302-7, and several positioning holes 302-8. The several positioning holes 302-8 are arranged on the outer ear plate 302-4 in a ring around the central axis 302-3.

[0024] Both pressure plate 302-6 and spring 302-5 are sleeved on the cylindrical shaft 302-1. There are two pressure plates 302-6, which are arranged symmetrically about spring 302-5. Pressure plate 302-6 abuts against spring 302-5. Locking pin 302-7 is fixed on pressure plate 302-6. Locking pin 302-7 passes through the reserved hole on inner ear plate 302-2 and then engages with one of the positioning holes 302-8.

[0025] A pull ring 302-9 is fixed on the pressure plate 302-6. In use, by pulling the pull ring 302-9, the locking pin 302-7 is disengaged from the positioning hole 302-8, and then the two adjacent horizontal connecting pieces 301 are rotated to adjust the included angle between them.

[0026] In this embodiment, the horizontal connector 301 has a rectangular frame structure, and its end is connected to the hinge locking device 302. The end of the pull screw 4 passes through the rectangular opening of the horizontal connector 301.

[0027] like Figure 5 As shown, the steel formwork 1 includes several formwork units 101 arranged sequentially from top to bottom, and two adjacent formwork units 101 are connected by a snap-fit ​​structure. In this embodiment, the snap-fit ​​structure includes a dovetail protrusion 102 and a dovetail groove 103. The dovetail protrusion 102 is located at the lower end of the formwork unit 101, and the dovetail groove 103 is located at the upper end of the formwork unit 101.

[0028] When the template unit 101 is installed and connected, the lateral sliding allows the dovetail protrusion 102 to be inserted into the dovetail groove 103, thus enabling the installation of two adjacent template units 101.

[0029] like Figures 6 to 9As shown, the elastic sealing component 2 includes slots 201 opened on the left and right sides of the template unit 101 and clamping strips 202 inserted into the slots 201; the two clamping strips 202 are fixed together by bolts, and a rubber plate 203 is clamped between the two clamping strips 202.

[0030] In this embodiment, the cross-section of the slot 201 is C-shaped. After the two clamping strips 202 clamp the rubber plate 203, its cross-section also becomes C-shaped, and the clamping strips 202 are inserted from one end of the slot 201.

[0031] In this embodiment, the longitudinal keel 6 is a rectangular square tube, and both the longitudinal keel 6 and the template unit 101 are provided with reserved holes through which the tie rod 4 passes.

[0032] The usage process of this invention is as follows: First, the curvature of the horizontal keel 3 is adjusted according to the curvature of the curved shear wall design. The curvature of the horizontal keel 3 is determined by multiple horizontal connectors 301 and hinge locking device 302. Then, the template unit 101 is assembled according to the height of the shear wall. The rubber plate 203 is clamped and fixed using clamping strips 202. Then, the clamping strips 202 are inserted into the slots 201 on the side of the steel template 1. At this time, a flexible template wall is formed by multiple steel templates 1 and multiple elastic sealing parts 2. A sleeve 7 is arranged between two template walls. The end of the tie rod 4 in the sleeve 7 passes through the steel template 1, the longitudinal keel 6, and the horizontal connector 301 and is connected to the first nut 5. The first nut 5 is tightened so that it presses against the horizontal keel 3. At this time, the curvature of the flexible template wall is constrained and fixed by the horizontal keel 3.

[0033] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
