[0002] Building structural reinforcement devices are devices or systems that enhance the load-bearing capacity, stability, or durability of existing building structures through mechanical, material, or engineering techniques. Their core objectives are to repair structural defects, improve safety, or adapt to new usage requirements.
[0003] When supporting and reinforcing a building structure, workers need to control the upward movement of the reinforcement structure until the reinforcement structure supports and reinforces the building structure. However, if the workers do not reasonably control the upward movement distance of the reinforcement structure, the reinforcement structure will move upward excessively and damage the building structure. In addition, it can only provide fixed-mode reinforcement and cannot automatically adjust its shape according to the type of building structure, which affects the reinforcement effect. Therefore, a reinforcement device based on the building structure is proposed. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0033] Example 1
[0034] like Figure 1 - Figure 10 As shown, the present invention proposes a reinforcement device based on a building structure, including a base 1, the upper part of the base 1 is rotatably connected to a circular plate 3, the upper part of the circular plate 3 is slidably provided with a movable rod 4, and a support plate 6 is installed at one end of the movable rod 4 away from the base 1, and a locking assembly is provided between the support plate 6 and the movable rod 4. The locking assembly includes a linkage unit jointly arranged between the support plate 6 and the movable rod 4, a pressure plate 10 movably connected to the upper part of the support plate 6, a pressure block 17 slidably arranged on the inner side of the movable rod 4, and a movable block 20 movably connected to the end of the pressure block 17. A plurality of first fixing grooves 21 are provided on the inner side of the circular plate 3. When the support plate 6 moves upward and contacts the building structure, the pressure plate 10 moves downward, and the pressure plate 10 moves downward to drive the pressure block 17 to move. The pressure block 17 moves and drives the movable block 20 to insert into the first fixing groove 21 to lock the support plate 6, which prevents the support plate 6 from excessively moving upward to damage the building structure and avoids rigid impact to damage the equipment itself.
[0035] The support plate 6 is provided with a reinforcement assembly, which includes a transmission unit provided on the support plate 6, a clamping plate 23 symmetrically connected to the upper portion of the support plate 6, a pushing plate 28 installed on the side of the clamping plate 23, an extension plate 31 symmetrically slidingly provided on the inner side of the support plate 6, and a plurality of limit plates 35 movably connected to the inner side of the support plate 6. A second fixed groove 32 is provided on the upper portion of the extension plate 31. When the support plate 6 contacts the building structure, the transmission unit is started to drive the two clamping plates 23 to rotate and clamp the building structure. When reinforcing the planar building structure, the two clamping plates 23 are driven to be parallel to the support plate 6 by the transmission unit. When the clamping plate 23 rotates, the pushing plate 28 squeezes the limit plate 35 and drives the limit plate 35 to move up and move to the outside of the second fixed groove 32, and the two extension plates 31 move to the outside of the support plate 6. The two extension plates 31, the clamping plate 23 and the support plate 6 jointly reinforce the building structure, and the reinforcement state can be changed according to different building structures to improve the reinforcement effect.
[0036] The inner side of the base 1 is rotatably connected to a driving device 2, which is fixedly connected to the circular plate 3. The output shaft of the driving device 2 extending to the inner side of the circular plate 3 is installed with a threaded rod 5, which is threadedly connected to the movable rod 4. The driving device 2 drives the threaded rod 5 to rotate, and when the threaded rod 5 rotates, it drives the movable rod 4 to move up along the circular plate 3.
[0037] The linkage unit includes a first sliding groove 7 provided between the support plate 6 and the movable rod 4, a push rod 8 is slidingly provided on the inner side of the first sliding groove 7, and the push rod 8 is fixedly connected to the pressure plate 10. A square groove 9 is provided on the upper part of the support plate 6, and the size of the square groove 9 opening is adapted to the size of the pressure plate 10. After being squeezed by the building structure, the pressure plate 10 moves into the square groove 9, thereby driving the push rod 8 to move downward along the first sliding groove 7.
[0038] A first telescopic rod 12 and a first spring 11 are respectively installed on the inner side of the first sliding groove 7. The first spring 11 is sleeved on the outer side of the first telescopic rod 12. The ends of the first spring 11 and the first telescopic rod 12 are fixedly connected to the push rod 8.
[0039] A first open groove 13 is provided on the inner side of the movable rod 4, and a square plate 14 is installed on the inner side of the first open groove 13. The side surfaces of the square plate 14 are respectively installed with a second telescopic rod 15 and a second spring 16. The second spring 16 is sleeved on the outer side of the second telescopic rod 15. The ends of the second telescopic rod 15 and the second spring 16 are fixedly connected to the pressure block 17, and the pressure block 17 is on the movement trajectory of the push rod 8.
[0040] A third spring 18 and a third telescopic rod 19 are respectively installed on the side of the pressure block 17 away from the push rod 8. The ends of the third spring 18 and the third telescopic rod 19 away from the pressure block 17 are fixedly connected to the movable block 20. When the pressure block 17 moves, it can drive the movable block 20 to be inserted into the first fixed groove 21.
[0041] In this embodiment, when it is necessary to reinforce the building structure, the driving device 2 can be started, and the threaded rod 5 can be driven to rotate by the driving device 2. The force generated when the threaded rod 5 rotates can drive the movable rod 4 to move up along the circular plate 3, thereby driving the support plate 6 to move up until the support plate 6 contacts the building structure to support and reinforce the structure. When the support plate 6 contacts the building structure, the pressure plate 10 can be squeezed and the pressure plate 10 moves into the square groove 9, thereby driving the push rod 8 to move down along the first sliding groove 7. When the push rod 8 moves down, the first spring 11 and the first telescopic rod 12 contract, and the push rod 8 squeezes The inclined surface of the pressure block 17 drives the pressure block 17 to move. At this time, the second telescopic rod 15 and the second spring 16 are stretched. The pressure block 17 can drive the movable block 20 to insert into the first fixed groove 21 when moving, so that the movable rod 4 cannot move up, avoiding excessive upward movement of the support plate 6 and causing damage to the building structure. When it needs to move down, since the movable block 20 is connected to the pressure block 17 through the third spring 18 and the third telescopic rod 19, the movable block 20 is driven to squeeze the circular plate 3 when the movable rod 4 moves down. The circular plate 3 is contracted by the elasticity of the third spring 18 and the third telescopic rod 19, which will not affect the downward movement of the movable rod 4.
[0042] Example 2

The first rotating rod 22 is fixedly connected to the clamping plate 23, and the second rotating rod 27 is rotatably connected to the inner side of the support plate 6. The third rotating rod 36 is rotatably connected to the inner side of the support plate 6. A first transmission belt 24 is commonly sleeved between the servo motor 25 and the second rotating rod 27, and a third transmission belt 39 is commonly sleeved between the second rotating rod 27 and the third rotating rod 36. A second transmission belt 26 is commonly sleeved between the output end of the servo motor 25 and the second rotating rod 27. A second gear 38 is installed on the outer side of the first rotating rod 22 near the second rotating rod 27, and a first gear 37 is installed on the outer side of the third rotating rod 36. The first gear 37 is meshed with the second gear 38, driving the two clamping plates 23 to rotate in opposite directions, and the building structure is clamped by the two clamping plates 23.
[0044] A second opening groove 29 is symmetrically opened on the inner side of the support plate 6, and a fourth spring 30 is symmetrically installed on the inner side of the second opening groove 29. The end of the fourth spring 30 is fixedly connected to the extension plate 31, and the extension plate 31 is slidably connected to the second opening groove 29. The end of the extension plate 31 is in the same horizontal plane as the support plate 6. The building structure is reinforced by the two extension plates 31, the two clamping plates 23 and the support plate 6.

[0046] The limiting plate 35 is located on the movement track of the pushing plate 28 , and the pushing plate 28 can press the limiting plate 35 after rotating.
[0047] In this embodiment, when the support plate 6 contacts the building structure, the servo motor 25 can be started at this time. When the output shaft of the servo motor 25 rotates, the second rotating rod 27 can be driven to rotate through the second transmission belt 26. Therefore, the first transmission belt 24 of the output shaft of the servo motor 25 drives the first rotating rod 22 to rotate, and the second rotating rod 27 can drive the third rotating rod 36 to rotate through the third transmission belt 39. The third rotating rod 36 simultaneously drives the first rotating rod 22 near the side of the second rotating rod 27 to rotate in the opposite direction through the first gear 37 and the second gear 38, thereby driving the two clamping plates 23 to rotate in opposite directions, and the building structure is clamped by the two clamping plates 23 to improve the reinforcement. The stability of the work. If it is necessary to support the planar building structure, the servo motor 25 drives the two clamping plates 23 to rotate and be parallel to the support plate 6. After the clamping plate 23 rotates, it can drive the push plate 28 to rotate. After the push plate 28 rotates, it can squeeze the limit plate 35, thereby driving the limit plate 35 to move upward. At this time, the limit plate 35 moves to the outside of the second fixed groove 32 and no longer limits the extension plate 31. The fourth spring 30 in the contracted state is reset, thereby driving the extension plate 31 to move to the outside of the second opening groove 29. The two extension plates 31, the two clamping plates 23 and the support plate 6 are used to reinforce the building structure and increase the support area.
