[0003] After the traditional formwork is poured, a frame-shaped inner wall is formed. The door and window are installed in the door and window opening, and waterproof material is filled between the outer side of the door and window frame and the inner side wall of the door and window opening, so as to reduce the possibility of leakage between the gap between the door and window and the inner side wall of the concrete door and window opening. However, the cooperation area between the outer side of the door and window frame and the inner side wall of the door and window opening is small, so the phenomenon of leakage between the door and window and the inner side wall of the door and window opening occurs from time to time in reality.

[0007] By using the above technical solution, the back battens are enclosed on the outer side of the formwork frame and flush with the outer side surface of the wall after pouring is completed. After the concrete solidifies, the supporting device, the formwork frame and the back battens are removed to form a door and window opening. A back-shaped installation groove is formed at the back batten. The door and window frame is installed in the back-shaped installation groove formed by the back batten. Waterproof material is brushed or filled between the outer side surface of the door and window frame and the inner circumferential wall of the back-shaped installation groove, and between the side surface of the door and window frame and the side wall of the back-shaped installation groove. Since one side surface and the outer side surface around the door and window frame are filled with waterproof material between the inner wall of the back-shaped installation groove, the cooperation area of the door and window frame and the inner wall of the door and window opening is increased, and the waterproof performance between the door and window frame and the inner side wall of the door and window opening is improved.

[0010] Preferably, the driving mechanism comprises a sleeve ring rotatably arranged on the fixed tube, the sleeve ring is sleeved on the threaded rod, the sleeve ring is threadedly connected with the threaded rod, and a limiting piece is arranged between the threaded rod and the fixed tube to prevent the threaded rod from rotating relative to the fixed tube.

[0011] By adopting the above technical scheme, the sleeve ring is rotatably arranged on the fixed tube, the sleeve ring is threadedly connected with the threaded rod, and when the sleeve ring is rotated, the threaded rod can move along the axial direction of the fixed tube under the action of the limiting piece, so that the supporting device can be adjusted according to the template frame, thereby improving the application range of the supporting device.

[0012] Preferably, a limiting groove is formed in the inner wall of the fixed tube, the limiting piece is fixed to the threaded rod, the limiting piece is inserted into the limiting groove, and the limiting piece is slidingly arranged in the limiting groove.

[0013] By adopting the above technical scheme, the limiting groove is formed in the inner wall of the fixed tube, the limiting piece is fixed to the threaded rod, the limiting piece is inserted into the limiting groove, and the limiting piece is slidingly arranged in the limiting groove, thereby preventing the threaded rod from sliding relative to the fixed tube, so that when the sleeve ring is rotated, the threaded rod can stably slide along the axial direction of the fixed tube.

[0014] Preferably, the supporting device is arranged in the template frame in at least one group in the transverse direction and the longitudinal direction, respectively, a control device is arranged on the supporting device arranged in the longitudinal direction, the control device comprises an electric motor fixedly connected to the fixed tube, a driven gear is sleeved on the outer circumferential surface of the sleeve ring, the driven gear is fixedly connected with the sleeve ring, a driving gear is fixedly connected to the output shaft of the electric motor and engaged with the driven gear, and the control device further comprises a trigger mechanism for detecting the bending degree of the pouring formwork at the top of the door and window opening, and the trigger mechanism controls the start and stop of the electric motor.

In the pouring process, due to vibration, sleeve loosening or keel strip deformation, the contact between the threaded rod and the keel strip may not be tight enough, so when the pouring formwork at the top of the door and window hole is bent due to the large pressure of the concrete on the top formwork, the trigger mechanism can control the motor to start. Since the driving gear is engaged with the driven gear, and the driven gear is fixed on the sleeve, the motor can automatically adjust the length of the supporting device when the motor is started, preventing the pouring formwork from continuing to bend downward, improving the stability of the pouring formwork structure and reducing the size error of the door and window hole.

[0016] Preferably, the trigger mechanism comprises a rigidity detection rod arranged on the side surface of the top keel strip, both ends of the rigidity detection rod are provided with a waist-shaped hole, a pin shaft is inserted in the waist-shaped hole, the pin shaft is fixed on the keel strip, a space is left between the top surface of the rigidity detection rod and the bottom surface of the pouring formwork at the top, a fixed seat is fixedly connected to the bottom surface of the pouring formwork, a sliding groove is formed in the bottom surface of the fixed seat, a trigger block that can be in contact with the rigidity detection rod is slidably arranged in the sliding groove, a fixed contact is embedded on the inner wall of the sliding groove, a movable contact that can be in contact with the fixed contact is embedded on the trigger block, a power supply is fixedly connected to the fixed tube, the movable contact and one electrode of the power supply are electrically connected, the other electrode of the power supply and one terminal post of the motor are electrically connected, and the other terminal post of the motor and the fixed contact are electrically connected.

[0017] By adopting the technical scheme, the rigidity detection rod is fixed on the side surface of the keel strip through the pin shaft. When the contact between the threaded rod and the keel strip is not tight enough and the pouring formwork is bent by the concrete, the rigidity detection rod can contact the trigger block and push the trigger block into the sliding groove, so that the movable contact and the fixed contact are in contact. At this time, the electric circuit of the motor is conducted, the motor automatically drives the threaded rod to move upward, so that the threaded rod restores the pouring formwork through the keel strip.

[0021] By adopting the above technical scheme, the annular plate is rotatably arranged in the annular groove, thereby preventing the collar from being separated from the fixing tube, and enabling the sleeve to be stably rotatably arranged on the fixing tube.

[0022] Preferably, the end of the threaded rod away from the fixing tube is fixedly connected with a contact plate, and the contact plate is in contact with the side of the keel away from the pouring formwork.

[0023] By adopting the above technical scheme, the contact plate is in contact with the side of the keel away from the pouring formwork, thereby increasing the contact area between the support device and the keel and enabling the threaded rod to be in more stable contact.

[0024] In a second aspect, the application provides a construction method for a seepage-proof door and window opening, which adopts the following technical scheme:

[0025] The construction method for a seepage-proof door and window opening comprises the following steps: S1: connecting the pouring formworks to each other; S2: fixing the keels on the inner side surfaces of the pouring formworks, wherein the keels are connected to each other; S3: fixing the back batten strips on the outer side surfaces of the pouring formworks, wherein the back batten strips are connected to each other; S4: installing the support devices inside the formwork frames; and S5: installing the control devices on the vertically arranged support devices.

[0026] By adopting the above technical scheme, the back batten strips are connected to each other on the outer side surfaces of the formwork frames and are flush with the outer side surfaces of the wall after the pouring is completed.

When the pouring formwork is bent, the control device can automatically lift the pouring formwork to correct the pouring formwork, thereby reducing the size error of the door and window opening.

[0027] In summary, the application has at least one of the following beneficial technical effects:

[0028] 1. The back strip is enclosed outside the formwork frame, and is flush with the outer side of the poured wall. After the concrete is solidified, the support device, formwork frame and back strip are removed, forming a door and window opening. A back-shaped mounting groove is formed at the back strip. The door and window frame is installed in the back-shaped mounting groove formed by the back strip. Waterproof material is applied or filled between the outer side of the door and window frame and the inner wall of the back-shaped mounting groove, and between the side of the door and window frame and the side wall of the back-shaped mounting groove. Since one side of the door and window frame and the outer side around it are filled with waterproof material between the inner wall of the back-shaped mounting groove, the cooperation area of the door and window frame and the inner wall of the door and window opening is increased, and the waterproof performance between the door and window frame and the inner wall of the door and window opening is improved.

[0029] 2. The motor is fixed on the fixed pipe, the drive gear is fixed on the output shaft of the motor, and the driven gear is fixed on the sleeve. The driven gear is engaged with the drive gear, and the motor can drive the sleeve to rotate when the motor is started. During pouring, due to vibration, loosening of the sleeve or deformation of the keel strip, the contact between the threaded rod and the keel strip may not be tight enough. Therefore, when the pouring formwork at the top of the door and window opening is bent due to the large pressure of the concrete on the top formwork during pouring, the trigger mechanism can control the motor to start. Since the drive gear is engaged with the driven gear, and the driven gear is fixed on the sleeve, the motor can automatically adjust the length of the support device when the motor is started, preventing the pouring formwork from continuing to bend downward, improving the stability of the pouring formwork structure, and reducing the size error of the door and window opening.

[0030] 3. The rigid detection rod is fixed on the side of the keel strip through the pin shaft. When the contact between the threaded rod and the keel strip is not tight enough and the pouring formwork is bent by the concrete, the rigid detection rod can contact the trigger block and push the trigger block into the sliding groove, so that the movable contact piece contacts the fixed contact piece. At this time, the electric circuit of the motor is conducted, and the motor automatically drives the threaded rod to move upward, so that the threaded rod passes through the keel strip to reset the pouring formwork. During the resetting process of the pouring formwork, the trigger block gradually slides out of the sliding groove until the pouring formwork is reset. The movable contact piece and the fixed contact piece are separated, so that the motor automatically stops. BRIEF DESCRIPTION OF DRAWINGS
