In a specific embodiment of the present invention, the angle between the connecting plate 19 and the first template 1 and the angle between the connecting plate 19 and the second template 2 are both 135°.
[0040] The right side of the first template 1 can be set in any suitable direction, see Figure 1 As shown, in a specific embodiment of the present invention, the right side of the first template 1 is vertically arranged and tilted toward the right rear from left to right.
[0041] The angle between the right side surface of the first template 1 and the vertical plane arranged vertically and along the left-right direction can be any suitable angle. In a specific embodiment of the present invention, the angle between the right side surface of the first template 1 and the vertical plane arranged vertically and along the left-right direction is 45°.

[0043] The angle between the rear side surface of the second template 2 and the vertical plane arranged vertically and along the front-to-back direction can be any suitable angle. In a specific embodiment of the present invention, the angle between the rear side surface of the second template 2 and the vertical plane arranged vertically and along the front-to-back direction is 45°.
[0044] The middle portion of the adjusting screw 9 can have any suitable configuration, see Figure 1 As shown, in a specific embodiment of the present invention, a rotation-assisting insertion hole 20 is vertically provided in the middle of the adjusting screw 9. With this arrangement, when the adjusting screw 9 needs to be rotated about its axis, another auxiliary rotating rod is vertically inserted into the rotation-assisting insertion hole 20. By holding both ends of the auxiliary rotating rod and rotating it about the axis of the adjusting screw 9, the auxiliary rotating rod is rotated to assist in rotating the adjusting screw 9, thereby saving effort.
[0045] The first template 1 and the second template 2 can be plates made of any suitable material. In a specific embodiment of the present invention, the first template 1 and the second template 2 are both steel plates.
[0046] The first keel 3, the second keel 4, the first main keel 5 and the second main keel 6 can be any suitable building components. In a specific embodiment of the present invention, the first keel 3, the second keel 4, the first main keel 5 and the second main keel 6 are all square steels.
[0047] The number of the first keels 3 and the number of the second keels 4 can be determined as needed. The above "multiple" refers to more than 2, see Figure 1 As shown, in a specific embodiment of the present invention, the number of the first keels 3 and the number of the second keels 4 are both 7.
[0048] When in use, the present invention can be directly used for the construction of 90° internal angle templates; if the internal angle is less than 90°, the adjusting screw 9 can be rotated around the axis of the adjusting screw 9, so that the first adjusting link 8 and the second adjusting link 10 are close to each other along the tilt direction of the adjusting screw 9, thereby pulling the first main keel 5 and the second main keel 6 closer, and then pulling the first template 1 and the second template 2 closer through the first keel 3 and the second keel 4 respectively, so that the angle between the first template 1 and the second template 2 becomes smaller, such as Figure 4 As shown; if the inner angle is greater than 90°, the adjusting screw 9 can be rotated in the opposite direction around the axis of the adjusting screw 9, so that the first adjusting link 8 and the second adjusting link 10 move away from each other along the tilt direction of the adjusting screw 9, thereby pushing the first main keel 5 and the second main keel 6 away, and then pushing the first template 1 and the second template 2 away through the first keel 3 and the second keel 4 respectively, so that the angle between the first template 1 and the second template 2 becomes larger, as shown in FIG. Figure 5 As shown in the figure, the internal corner template can be precisely corrected by slightly adjusting the included angle of the internal corner template.
[0049] When removing the formwork, the above method can be used to reduce the angle of the internal corner formwork, generate a pulling force toward the inside of the formwork, and realize the autonomous removal of the formwork.
[0050] Therefore, by adopting the utility model, by rotating the adjusting screw, the internal power of the angle adjustment reinforcement device is formed, which drives the first adjusting link and the second adjusting link to move toward the middle or both ends of the adjusting screw, driving the first main keel and the second main keel, the first keel and the second keel, and the first template and the second template to move closer to or away from each other, thereby achieving the purpose of freely adjusting the angle of the internal corner template.
[0051] The angle adjustment reinforcement device's two end supports connect the first and second formworks, forming a triangular, stable support structure. Preferably, connecting plates connect the right side of the first formwork and the rear side of the second formwork, forming an obtuse angle. This reduces the area on either side of the angle subject to adhesive stress when the formwork is removed. Simultaneously, adjusting the formwork angle toward a smaller angle creates tension on both sides of the internal corner formwork, separating it from the concrete contact surface and achieving a self-detachable formwork.
[0052] The present invention allows for more precise corner formwork correction, flexible formwork angle adjustment, and simplified operation, improving work efficiency. It effectively addresses technical challenges such as precise angle adjustment, variable angle installation, and removal of formwork at internal corners of concrete structures. Compared to existing technologies, the present invention increases formwork installation speed, enhances precise positioning of corner formwork, accelerates removal, and achieves superior forming results. It is quick and easy to operate, allows for free adjustment of the angle, and significantly improves internal corner formwork construction speed and efficiency.
[0053] In summary, the angle-adjustable and easy-to-dismantle internal corner template reinforcement structure of the present invention can effectively support the internal corner template, and can adjust the angle of the internal corner template to facilitate the dismantling of the internal corner template. It has a clever design, a simple structure, is easy to manufacture, and has a low manufacturing cost, and is suitable for large-scale promotion and application.
[0054] It can be seen that the purpose of this utility model has been fully and effectively achieved. The functional and structural principles of this utility model have been demonstrated and explained in the embodiments. Without departing from the principles described, the embodiments may be modified in any way. Therefore, this utility model includes all modified embodiments based on the spirit and scope of the claims.
