Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1 Please refer to Figures 1-4 , the present invention provides a technical solution:

[0024] A standardized formwork reinforcement device for door and window openings, including a shear wall formwork 1 for door and window openings. A door and window opening reinforcement wooden square 2 is circumferentially connected near the inner wall of the shear wall formwork 1 for door and window openings. A side formwork 3 for door and window openings is fixedly installed inside the door and window opening reinforcement wooden square 2. A fillet connecting member 4 is connected at an angle near the inner wall of the door and window opening reinforcement wooden square 2, and the surface of the fillet connecting member 4 is fixedly connected to the surface of the side formwork 3 for door and window openings. The inside of the shear wall formwork 1 for door and window openings is connected to the end face of the side formwork 3 for door and window openings.

[0025] Specifically, as Figures 1-4As shown, the internal corner connecting member 4 is composed of an ∠100x10 angle steel 401, a triangular support member 402, a φ12 screw rod 403, a nut 404, and a backing plate 405. The surface near the center of the ∠100x10 angle steel 401 and the surface near the middle of the triangular support member 402 are fixedly installed with the surface of the φ12 screw rod 403. The nut 404 is threadedly connected to the surface near the bottom of the φ12 screw rod 403, and the backing plate 405 abuts against the top of the nut 404. One end of the reinforcing square timber 2 for the door and window opening extends into the gap between the ∠100x10 angle steel 401 and the triangular support member 402, and the contact ends of the reinforcing square timber 2 for the door and window opening with the ∠100x10 angle steel 401 and the triangular support member 402 are threadedly connected to the φ12 screw rod 403. The ∠100x10 angle steel 401 and the φ12 screw rod 403 are connected by welding. The triangular support member 402 is formed by connecting an ∠150x5 angle steel and a 5-mm-thick steel plate by welding. The ∠100x10 angle steel 401 and the triangular support member 402 are connected by the φ12 screw rod 403, and the ∠100x10 angle steel 401 is located at one end of the vertical line of the triangular support member 402. The backing plate 405 and the nut 404 are located at the end away from the ∠100x10 angle steel 401, and two φ12 screw rods 403 are vertically arranged on a single internal corner connecting member 4. The reinforcing square timber 2 for the door and window opening is extended into the gap between the ∠100x10 angle steel 401 and the triangular support member 402, connected by the φ12 screw rod 403, and fastened by the backing plate 405 and the nut 404 sleeved on the upper φ12 screw rod 403. The inside of the door and window opening is internally braced and reinforced by arranging longitudinal, transverse, and diagonal reinforcing square timbers 2 for the door and window opening to prevent the reinforcing device from being compressed and deformed. The door and window opening shear wall formwork 1 and the door and window opening side formwork 3 are connected as a whole.

[0026] Example 2 Please refer to Figures 1-4, the difference between this embodiment and Embodiment 1 is that: an anti-slip card slot 5 is provided on the front side of the side formwork 3 of the door and window opening. An anti-slip card plate 6 is clamped on the inner wall of the anti-slip card slot 5. The anti-slip card plate 6 is fixedly connected to a spring telescopic rod 7. The output end of the spring telescopic rod 7 is fixedly connected to a cross plate 8. A rotating screw rod 9 is rotatably connected to the inside of the cross plate 8 through a bearing. A threaded sleeve plate 10 is threadedly connected to the threaded surface of the rotating screw rod 9. A limiting component is connected to one side of the threaded sleeve plate 10. One end of the threaded sleeve plate 10 is rotatably connected to a positioning suction cup 11 through a bearing. The limiting component includes a limiting inner rod 12 and a limiting outer sleeve 13. The limiting inner rod 12 is fixedly connected to the surface of the cross plate 8. The limiting outer sleeve 13 is fixedly connected to one side of the threaded sleeve plate 10 and is fixedly connected to the inside of the threaded sleeve plate 10. The inner wall of the limiting outer sleeve 13 is slidably connected to the surface of the limiting inner rod 12. When the side formwork 3 of the door and window opening slowly enters the door and window opening of the shear wall formwork 1 of the door and window opening, the rotating screw rod 9 can be rotated. Under the constraint of the limiting inner rod 12 and the limiting outer sleeve 13, the movement track of the threaded sleeve plate 10 is limited, so that the rotation of the rotating screw rod 9 can drive the threaded sleeve plate 10 to move, and can drive the cross plate 8 and the entire side formwork 3 of the door and window opening to move, and compress the spring telescopic rod 7 for subsequent adaptation to the card-in effect of the door and window opening in the shear wall formwork 1 of the door and window opening.

[0027] Working principle of the utility model: During use, the staff can first firmly fix the contact surface between the reinforcing wooden square 2 of the door and window opening and the side formwork 3 of the door and window opening with nails or connect them by rotating a screw rod. The anti-slip card slot 5 on the side formwork 3 of the door and window opening can be used for the clamping and positioning of the anti-slip card plate 6, so as to form the cross plate 8 at the front side of the shear wall formwork 1 of the door and window opening. With the help of the positioning suction cup 11 at the front side of the shear wall formwork 1 of the door and window opening, after the basic position of the side formwork 3 of the door and window opening is positioned, the side formwork 3 of the door and window opening slowly enters at the door and window opening of the shear wall formwork 1 of the door and window opening. The rotating screw rod 9 can be rotated. Under the restraint of the limit inner rod 12 and the limit outer sleeve 13, the movement track of the threaded sleeve plate 10 is limited, so that the rotation of the rotating screw rod 9 can drive the threaded sleeve plate 10 to move, and can drive the cross plate 8 and the entire side formwork 3 of the door and window opening to move, and compress the spring telescopic rod 7 to adapt to the clamping effect of the door and window opening in the shear wall formwork 1 of the door and window opening. The reinforcing wooden square 2 of the door and window opening is extended into the gap between the ∠100x10 angle steel 401 and the triangular support 402, and is connected by the φ12 screw rod 403, and is tightened by the backing plate 405 and the nut 404 sleeved on the upper φ12 screw rod 403. The inside of the door and window opening is internally braced and reinforced by arranging longitudinal, transverse and diagonal reinforcing wooden squares 2 of the door and window opening to prevent the reinforcing device from being deformed under pressure. The shear wall formwork 1 of the door and window opening and the side formwork 3 of the door and window opening are connected as a whole. After all the pouring formworks are supported, concrete is poured. After the concrete solidifies, the pouring formwork and this reinforcing device are removed, thus completing the quick and stable reinforcement effect on the door and window structure.

[0028] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
