[0002] The Chinese invention patent with the publication number CN110965746B discloses a fixing device for interior wall decorative panels of prefabricated buildings, which comprises installing a Wright gas rod on the top surface of a movable seat, welding a rotating seat at the end of the piston rod of the Wright gas rod, arranging an adjustment component in the rotating seat, arranging a clamping component at the front end of the adjustment component, and arranging a power component at the rear end of the rotating seat, clamping and fixing the interior wall decorative panel to be installed by the clamping component, driving the adjustment component to rotate on the horizontal axis by the power component, so that the horizontally placed clamping component rotates to a vertical state, and then driving the adjustment component to rotate on the vertical axis by the power component, so that the clamping component drives the interior wall decorative panel to calibrate the installation position, thereby facilitating the connection and fixing of the interior wall decorative panel and the interior wall. The present invention not only saves time and effort, but also helps to improve the installation efficiency of the interior wall decorative panel.

[0003] A Chinese invention patent with publication number CN112502413B discloses a device for fixing interior wall decorative panels of prefabricated buildings. The first adjustment component and the second adjustment component are used to drive the positioning plate to move inward, clamp the four sides of the decorative panel, and fix the decorative panel; the fixing mechanism drives the decorative panel to rotate to a vertical state through the main shaft, and the fixing mechanism and the decorative panel are moved outward through the hydraulic telescopic rod and the push plate, so that the decorative panel is close to the wall, so as to install the decorative panel, etc.; when the decorative panel is installed, the fixing mechanism located at the top can place and fix the decorative panel at the same time, thereby speeding up work efficiency. Although the interval time between two decorative panel installations is shortened, due to the large wall panels, the device is large in size and cannot meet the operation requirements of indoor environments of different sizes.

[0004] In the related art, in order to improve the installation effect of the interior wall, a corresponding wall panel fixing device is usually required for auxiliary operation. However, when operating the existing interior wall fixing device, it is often necessary to manually erect the wall panel, and it lacks the self-erecting function. Due to the large volume and weight of the interior wall or interior wall decorative panel, the operation is time-consuming and labor-intensive, and the wall panel after being fixed lacks the fine-tuning function. The fixing device needs to be adjusted as a whole to meet the corresponding assembly work of the wall panel, which reduces the auxiliary effect of the fixing device. Summary of the invention

[0040] By setting the lifting assembly 6, the inner wall strips 3 laid flat on the ground can be erected, and by the longitudinal driving of the Z-shaped sliding frame 42 and the U-shaped positioning block 43 by the driving member in the fixing assembly 4, not only the erected inner wall can be positioned and fixed, but also the positioned and fixed inner wall can be longitudinally driven, so as to facilitate splicing and alignment with the outer wall or the already fixed and installed inner wall, thereby improving the fixing effect of the inner wall strips 3 and solving the problem that the fixing device in the prior art cannot fine-tune the fixed inner wall after fixing the inner wall, thereby affecting the convenience of subsequent inner wall assembly;

[0041] The opening of the U-shaped positioning block 43 is expanded to facilitate the U-shaped positioning block 43 to better position and fix the inner wall during the erection process, thereby forming a calibration and fine-tuning work for the inner wall. An electric clamping member for fixing the inner wall strip 3 can be arranged inside the U-shaped positioning block 43 to further improve its fixing effect.

[0042] The telescopic assembly 5 is connected to the L-shaped base 1 in a convenient disassembly manner, which not only facilitates the rapid disassembly and assembly of the fixing device by the staff, but also satisfies the operation in different indoor environments, thereby increasing the use range of the equipment;

[0049] The bottom end of the telescopic frame 53 is inserted into the latch hole 52 at the corresponding position, thereby facilitating the detachable installation of the telescopic component 5 and the L-shaped base 1. This not only facilitates the staff to quickly disassemble and assemble the fixing device, but also meets the operation requirements of different indoor environments, thereby increasing the scope of use of the equipment.

[0050] Refer to the attached Fig. 9 The lifting assembly 6 includes a fixed plate 61 fixed between the tops of the two telescopic blocks 54, the top of the fixed plate 61 is rotatably connected to a winding wheel 62 through a bracket, a rope 63 is wound around the outer surface of the winding wheel 62, one end of the rope 63 is fixedly connected to a hook 64, one end of the rope 63 is connected to a binding member for limiting the top of the inner wall strip 3 through the hook 64, the top of the fixed plate 61 is fixedly connected to a second motor 65 for driving the winding wheel 62 to rotate forward and reverse, the output shaft of the second motor 65 is fixedly connected to the axial rod of the winding wheel 62, and one side of the fixed plate 61 is rotatably connected to a guide sleeve 68 through a bracket;

[0052] One end of the rope 63 is connected to the binding piece by a hook 64, which can drive the inner wall slats 3 laid flat on the ground to perform a fan-shaped movement to press against the position of the component 2, thereby forming a lifting and vertical operation of the inner wall slats 3. This not only facilitates the fixation of the inner wall slats 3 by the equipment and improves the subsequent installation of the inner wall slats 3, but also eliminates the need for manual uprighting work, thereby solving the problem in the prior art that the inner wall slats 3 are large in size and weight, making them inconvenient to operate upright. The guide sleeve 68 is provided to guide the rope 63, thereby improving the lifting effect of the inner wall slats 3.

[0053] Refer to the attached Fig. 9 The binding member includes a connecting belt 66 for wrapping the top of the inner wall strip 3, and both ends of the connecting belt 66 are fixedly connected to a hanging ring 67 through a connecting rope;

[0054] The connection belt 66 is provided to bundle the inner wall strips 3, and the two hanging rings 67 are provided to facilitate the connection between the two ends of the connection belt 66 and the hooks 64, thereby facilitating the winding of the rope 63 to form the lifting work of the inner wall strips 3. After the inner wall strips 3 are lifted upright, they can be removed.

[0055] The working principle of the inner wall fixing device of an assembled building of the present invention is as follows:

[0056] By setting the connecting belt 66, one end of the inner wall strip 3 lying flat on the ground is tied up, and then connected to the hook 64 through two hanging rings 67.

One end of the rope 63 is connected to the binding piece through the hook 64, and then the inner wall strip 3 lying flat on the ground can be driven to move in a fan-shaped manner at the position of the tight assembly 2, forming a lifting and vertical operation of the inner wall strip 3;

[0057] After the inner wall strip 3 is erected, the first motor 46 is started to drive the threaded rod 45 to rotate forward and backward. The forward and backward rotation of the threaded rod 45 can drive the Z-shaped sliding frame 42 to reciprocate longitudinally. The forward and backward movement of the Z-shaped sliding frame 42 can drive the U-shaped positioning block 43 to reciprocate longitudinally. The movement of the U-shaped positioning block 43 can wrap the inner and outer sides of the erected inner wall strip 3 to form a positioning and fixation of the inner wall strip 3. With the continuous movement of the U-shaped positioning block 43, the positioned and fixed inner wall strip 3 can be driven longitudinally to facilitate splicing and alignment with the outer wall or the inner wall that has been fixed and installed.

This not only facilitates the reinforcement work of the diagonal brace assembly 7 at different inclination angles, improves its reinforcement effect, but also is suitable for operation in different indoor environments.

[0061] A magnet block 75 is inserted at the top of the diagonal support rod 72, which can be locked in conjunction with a row of inclined blocks 74 to improve the stability of the diagonal support rod 72 after telescopic adjustment. In addition, the magnet block 75 is made of magnet material and the diagonal support rod 72 is made of steel material, which not only facilitates the self-locking of the magnet block 75 to the U-shaped guide rail 71, but also does not hinder the extension of the diagonal support rod 72, thereby improving the convenience of operation.

The U-shaped pad 24 is provided to support the bottom of the upright inner wall strip 3, which not only facilitates the subsequent fine-tuning and calibration of the inner wall strip 3, but also facilitates the laying of cement at the bottom of the inner wall strip 3 during the installation process, thereby improving its fixing effect.

[0065] The control component is used to drive the movable frame 21 to move left and right, and the left and right movement of the movable frame 21 can drive the fixing component 4 and the U-shaped pad 24 to move left and right, thereby fine-tuning and calibrating the inner wall strip 3 during the fixing process, thereby improving the functionality of the inner wall fixing device.

[0066] The control member includes a hydraulic cylinder 23 fixed to the bottom of the inner wall of the L-shaped base 1 through a bracket, and the telescopic end of the hydraulic cylinder 23 is fixedly connected to the mobile frame 21;
