At the same time, they can be reused, which also reduces construction costs.

[0003] A Chinese patent discloses a prefabricated building support device for construction engineering (publication number CN 220828087

[0004] U), this patent includes a box body, a support plate is slidably connected to the box body, the upper end of the support plate is symmetrically fixedly connected to a support rod, the end of the support rod away from the support plate is rotatably connected to a rotating rod, the end of the rotating rod away from the support rod is fixedly connected to a T-shaped support block, and a roller is arranged on the top of the box body. However, when adjusting the two groups of T-shaped support blocks, the T-shaped support blocks themselves cannot rotate, resulting in the rotation of the rotating rod. The top surfaces of the two groups of T-shaped support blocks will tilt, resulting in a reduction in the contact surface with the prefabricated building, making the prefabricated building more likely to slide or tilt, reducing the stability of the device. At the same time, there is a lack of middle support equipment between the two groups of T-shaped support blocks, which results in the need to withstand greater pressure on the limited contact points, which may cause damage to the T-shaped support blocks and affect the subsequent use of the device.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Please refer to Figure 1 , Figure 2, an assembled building support device for construction engineering, comprising a support column 1, the top of the support column 1 is rotatably connected with a connecting sleeve 2 through a bearing, both sides of the connecting sleeve 2 are fixedly installed with cross bars 3 by bolts, the top surfaces of the two cross bars 3 and the connecting sleeve 2 are installed with support plates 4 for supporting assembled buildings, the top surface of each group of support plates 4 is slidably installed with a positioning structure for clamping and fixing the assembled building, the outer surface thread sleeve of the support column 1 is provided with an adjustment structure for adjusting the distance between the two groups of support plates 4, and the bottom end of the support column 1 is fixedly installed with a lifting structure for adjusting the overall height of the device;

[0024] The adjustment structure includes a threaded ring 5, which is threadedly sleeved on the outer surface of the support column 1, and the outer surface of the support column 1 is provided with a threaded groove for providing the threaded ring 5 with up and down movement, and both sides of the threaded ring 5 are rotatably connected with movable rods 501 for pulling the support plate 4 to move, and a connecting block 502 is fixedly installed at one end of the movable rod 501 away from the threaded ring 5, and a connecting piece 503 for fixed connection with the support plate 4 is fixedly installed on one side of the connecting block 502;

[0025] Specifically, both ends of the movable rod 501 are rotatably mounted with clamping plates 504 for mounting and fixing the movable rod 501 through a shaft fixedly mounted therein, and two sets of clamping plates 504 are respectively fixedly connected to the threaded ring 5 and the connecting block 502;

[0026] More specifically, a driving motor 505 for providing rotational power to the supporting column 1 is fixedly installed at the bottom end of the supporting column 1, and the output end of the driving motor 505 is fixedly connected to the bottom end of the supporting column 1. The driving motor 505 drives the supporting column 1 to rotate, and the control threaded ring 5 connects a group of clamping plates 504 to drive the movable rod 501, and connects another group of clamping plates 504 to drive the connecting block 502 to drive the connecting member 503 to move along the cross bar 3, thereby adjusting the distance between the two groups of positioning structures according to the size of the prefabricated building. When the threaded ring 5 descends along the supporting column 1, it will drive the two groups of positioning structures to move synchronously to the center. The threaded ring 5 contracts at the center, effectively shortening the distance between the two sets of positioning structures, which is suitable for assembled buildings with smaller sizes. On the contrary, when the threaded ring 5 rises along the support column 1, it will drive the two sets of positioning structures to expand synchronously to both sides, effectively extending the distance between the two sets of positioning structures, which is suitable for assembled buildings with larger sizes. While ensuring the flexibility and wide applicability of the device, during the adjustment process, the two sets of positioning structures maintain stable linear movement, and thus the positioning structures do not need to be adjusted in angle, which greatly maintains the contact surface with the assembled building, avoids sliding or tilting, and improves the stability of the device;

[0027] The connecting piece 503 is slidably sleeved on the outer surface of the cross bar 3, and the internal thread connection of the connecting piece 503 is connected with a knob 506 for ensuring the fixed connection between the connecting piece 503 and the cross bar 3, and one side of the connecting block 502 is rotatably sleeved on the outer surface of the knob 506, both ends of the knob 506 pass through the cross bar 3, and nuts are provided to fix them. At the same time, a sliding groove for providing sliding of the connecting block 502 and the knob 506 is opened inside the cross bar 3. The tightness between the connecting piece 503 and the cross bar 3 is adjusted by rotating the knob 506, so as to rotate the connecting piece 503, thereby changing the inclination angle of the positioning structure, which helps the positioning structure to fit prefabricated buildings of different shapes, further expands the scope of use of the device, and enhances the practical value of the device.

[0028] See also Figure 1 , Figure 2 The outer surface of the connecting sleeve 2 is fixedly installed with an inclined rod 6, so that a triangular angle is formed between the support column 1 and the cross bar 3, and at the same time, a triangular angle of a larger area is formed in cooperation with the movable rod 501. The stability principle of the triangle is utilized to ensure that the device has a high degree of stability, effectively resist the external pressure brought to the device by the prefabricated building, evenly disperse and withstand the pressure, avoid the situation of excessive force on a single point, further enhance the stability of the structure, improve the load capacity of the device, and further maintain the safety and reliability of the device.

[0029] Example 2: Please refer to Figure 1 , Figure 3 The positioning structure includes a pressing plate 7, and a clamping plate 701 for clamping and fixing the assembled building is fixedly installed on one side of the pressing plate 7. The clamping plate 701 and the two sides of the pressing plate 7 are rotatably connected with sliding blocks 702, and are slidably installed on the upper surface of the supporting plate 4 through the sliding blocks 702; specifically, two pressing plates 7 and clamping plates 701 are arranged in each group of positioning structures, and the overall size of the clamping plate 701 is longer than the pressing plate 7, so that the clamping plate 701 is naturally unfolded and tilted on both sides when not subjected to external pressure, thereby driving the pressing plate 7 to warp up. When the pressing plate 7 contacts the assembled building, it is subjected to pressure, and the pressing plate 7 rotates downward until it is horizontally fitted with the supporting plate 4, and at the same time drives the two clamping plates 701 to rotate inward synchronously, thereby playing the role of clamping and fixing the assembled building, and using the assembled building's own gravity to achieve a fixed limiting effect, ensuring the stability and reliability of the fixation while simplifying the fixing steps, and the clamping plates 701 on both sides can effectively prevent the assembled building from shaking or displacement when subjected to external forces, further enhancing the fixing effect;

[0030] One side of the sliding block 702 is fixedly connected to a fixed plate 703, and one side of the fixed plate 703 is fixedly installed with a spring 704 for expanding the use range between the two clamping plates 701. The upper surface of the support plate 4 is provided with a movable groove for providing sliding of the sliding block 702 and the fixed plate 703, and the sliding block 702 and the fixed plate 703 are located in the movable groove. The clamping plate 701 is pushed to squeeze the spring 704 to move to both sides according to the size of the prefabricated building itself, so as to flexibly adjust the use range between the two clamping plates 701 according to the different sizes of the prefabricated building. At the same time, the squeezed and contracted spring 704 will release a reverse driving force to the clamping plate 701, thereby ensuring that the clamping plate 701 will not move at will, thereby ensuring the stability of the positioning structure.

[0031] See also Figure 1 , Figure 4 The lifting structure includes a positioning plate 8, which is fixedly mounted on the bottom surface of the driving motor 505. A bottom plate 801 is mounted on the bottom end of the positioning plate 8, and a hydraulic electric cylinder 802 for adjusting the height of the device is fixedly mounted in the gap between the two. The top of the hydraulic electric cylinder 802 is fixedly connected to the bottom surface of the positioning plate 8, and the bottom end of the hydraulic electric cylinder 802 is fixedly connected to the top surface of the bottom plate 801. The overall height of the device is adjusted by the extension and contraction of the hydraulic electric cylinder 802.

[0032] Four stabilizing rods 803 for ensuring the stability of the lifting device are fixedly installed on the top surface of the bottom plate 801. The top end of each stabilizing rod 803 passes through the positioning plate 8 and is fixedly installed with a limiting plate 804 for preventing the positioning plate 8 from falling off.

[0033] The working principle of the utility model is:

[0034] First, start the drive motor 505 to drive the support column 1 to rotate, control the threaded ring 5 to connect the movable rod 501, drive the connecting block 502 to drive the two sets of positioning structures to move closer or farther along the cross bar 3, until the distance between the two sets of positioning structures is adjusted to fit the size of the prefabricated building, and then start the hydraulic electric cylinder 802 to push the positioning plate 8 along the stabilizing rod 803 to drive the entire device to rise to fit the bottom surface of the prefabricated building, and finally the prefabricated building presses the pressing plate 7 downward to rotate it downward until it fits horizontally with the support plate 4, driving the two clamping plates 701 to rotate inward synchronously until they fit closely to the side surface of the prefabricated building, and at the same time use the size of the prefabricated building itself to push the clamping plate 701 to squeeze the spring 704 to move to both sides, adjust the appropriate range between the two clamping plates 701, and the squeezed and contracted spring 704 will also release a reverse driving force to the clamping plate 701, thereby playing a role in fixing and supporting the prefabricated building.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
