Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically relating to a construction deformation monitoring device and implementation method for a fan-shaped cantilever beam structure. Background Technology

[0002] Cantilever structures, with their unique shapes, have attracted the attention of architects and are increasingly being used in architectural works. The entire construction process of a large fan-shaped cantilever structure mainly includes: the construction of the central cylindrical column, the construction of the rotating thick shell connected to the column, and the construction of the outermost fan-shaped beam structure. Due to the asymmetrical double helix of the fan-shaped cantilever structure, the load borne by the core shell during the installation, tensioning, and loading of multiple structural beams is asymmetrical, time-varying, and extremely large. This complex stress state will cause cumulative three-dimensional spatial displacement of the core shell. If the deformation is not monitored and adjusted in time, it will cause inconsistencies between the constructed structure and the design state, leading to serious problems. Since the structural beams are installed step by step from bottom to top, existing technology can use the installed structural beams as a platform to directly monitor the deformation of their upper surfaces. However, monitoring the deformation of internal spaces such as the openings at the bottom of the structural beams remains difficult. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a construction deformation monitoring device and implementation method for a fan-shaped cantilever structural beam, which can monitor the deformation of the opening groove at the bottom of the structural beam, ensuring the installability and timeliness of the monitoring.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This invention discloses a construction deformation monitoring device for a fan-shaped cantilever beam. The beam includes a Z-shaped beam body with a vertical reinforcing plate integrally formed on the lower part of the beam body. A downward-opening slot is formed between the reinforcing plate and the beam body. The deformation monitoring device includes a first monitoring component, a second monitoring component, and a connecting plate for connecting the first and second monitoring components. The first monitoring component includes a support carrier, a monitoring head, a crawling wheel assembly, a linear motor, and a hollow rotating platform. The hollow rotating platforms corresponding to the first and second monitoring components are respectively installed at both ends of the connecting plate. The linear motor is connected to the hollow rotating platform. The upper end of the output shaft of the linear motor is connected to the support carrier, and the lower end passes through the center of the hollow rotating platform. Two sets of crawling wheel assemblies are symmetrically installed on both sides of the support carrier. The support carrier is supported inside the slot, and the monitoring head is installed on the support carrier.

[0006] Furthermore, the crawler wheel assembly includes a first hydraulic cylinder, a slide block, an elastic support rod, a parallel connecting rod, a deflection connecting rod, a vertical motor, a vertical roller, a horizontal motor, and a horizontal roller. The first hydraulic cylinder is mounted on the support carrier, and its output end is connected to the slide block. The slide block is slidably mounted on the support carrier along the lateral direction. The slide block is connected to the middle of the parallel connecting rod through the elastic support rod. The two ends of the parallel connecting rod are respectively connected to the support carrier through two mutually parallel deflection connecting rods. The vertical motor and the horizontal motor are mounted on the parallel connecting rod, and the vertical motor and the horizontal motor are respectively connected to the vertical roller and the horizontal roller.

[0007] Furthermore, the elastic support rod includes an inner rod, an outer rod, a pin, and a first support spring.

The inner rod is fixed to the outer side of one end of the outer rod with a pin, and the pin is slidably disposed in a groove on the outer rod. The two ends of the first support spring are respectively connected to the inner rod and the outer rod.

[0008] Furthermore, a ranging component is also installed on the support carrier. The ranging component includes a top rod, a bottom rod, a second support spring, a support roller, a roller seat, a trigger switch, and an indicator. The bottom rod is fixed on the support carrier, and the lower end of the top rod is slidably disposed inside the top rod. The bottom rod and the top rod are connected by the second support spring. A roller seat is installed at the upper end of the top rod, and a support roller is installed on the roller seat. A trigger switch is installed in the middle of the inner side of the bottom rod, and the trigger switch is connected to the indicator and the power supply through a circuit.

[0009] Furthermore, the connecting plate includes a first plate and a second plate that cooperate with the first monitoring component and the second monitoring component respectively. The end of the first plate away from the first monitoring component is slidably installed in a slot opened inside the second plate. Both the first plate and the second plate are provided with through holes for the output shaft of the linear motor to pass through. Both the first plate and the second plate are equipped with elastic buffers.

[0010] Furthermore, the elastic buffer includes a support plate, a central rod, a nut, a third support spring, and an elastic support foot. The support plate is connected to the first plate.

Detailed Implementation

[0027] like Figures 1-8 As shown, the present invention discloses a construction deformation monitoring device for a fan-shaped cantilever structural beam. The structural beam includes a Z-shaped beam body 1, and a vertical reinforcing plate 2 integrally formed on the lower part of the beam body 1. An opening groove 3 with a downward opening is formed between the reinforcing plate 2 and the beam body 1. Due to the high height of some fan-shaped cantilever structural beams and the downward opening groove 3, it is not convenient to monitor the deformation in the opening groove 3. Therefore, this device was invented. Figure 9 This is a structural schematic diagram of another embodiment of the structural beam. The specific operating principle of the device inside its opening slot is the same as that of the above embodiment, which should be understood by those skilled in the art.

[0028] Specifically, the deformation monitoring device disclosed in this invention includes a first monitoring component 4 and a second monitoring component 5 with identical structures, as well as a connecting plate for connecting the first monitoring component 4 and the second monitoring component 5. The first monitoring component 4 and the second monitoring component 5 have completely identical structures and are used to monitor two adjacent structural beams, respectively. Taking the first monitoring component 4 as an example, the first monitoring component 4 includes a support carrier 6, a monitoring head 7, a crawling wheel assembly 8, a linear motor 9, and a hollow rotating platform 10. The support carrier 6 is mainly used to support the entire device to prevent it from falling. The hollow rotating platforms 10 corresponding to the first monitoring component 4 and the second monitoring component 5 are respectively installed at both ends of the connecting plate. The linear motor 9 is connected to the hollow rotating platform 10. The upper end of the output shaft of the linear motor 9 is connected to the support carrier 6, and the lower end passes through the center of the hollow rotating platform 10. Two sets of crawling wheel assemblies 8 are symmetrically installed on both sides of the support carrier 6. The support carrier 6 is supported inside the opening slot 3. The monitoring head 7 is installed on the support carrier 6. The monitoring head 7 adopts existing monitoring devices, such as laser displacement sensors or photogrammetry instruments, to measure the deformation of the structural beam in the vertical or horizontal direction. The device can also measure the tilt of the structural beam. The specific measurement principle and equipment belong to the prior art. The support carrier 6 only provides support, which can be understood by those skilled in the art.

[0029] The implementation method of the construction deformation monitoring device for a fan-shaped cantilever beam according to the present invention is as follows:

[0030] With the length of the structural beam as the transverse direction, the first monitoring component 4 and the second monitoring component 5 are first installed in the opening slots 3 of the two structural beams respectively. The crawling wheel assembly 8 ensures they are tightly against the inner wall of the opening slot 3, preventing the device from falling downwards due to friction. During monitoring, the crawling wheel assembly 8 is activated, moving both monitoring components laterally. After monitoring is complete, the crawling wheel assembly 8 of the second monitoring component 5 is released, and the linear motor 9 of the second monitoring component 5 is activated, moving the second monitoring component 5 downwards until it is completely detached from the opening slot 3. At this time, the crawling wheel assembly 8 of the first monitoring component 4 remains stationary to ensure the device's stability. After the second monitoring component 5 has moved to its downward position, the central rotating platform of the first monitoring component 4 is activated, causing the connecting plate and the second monitoring component 5 to rotate around the center of the platform. When the second monitoring component 5 rotates to another structural beam, the linear motor 9 of the second monitoring component 5 is activated, moving the second monitoring component 5 upwards until it is installed in the opening slot 3 of that structural beam. Repeating this process allows for the monitoring of deformation in each structural beam.

[0031] It is understandable that the length direction of the support carrier 6 is also along the transverse direction. The crawling wheel assemblies 8 located on both sides of the support carrier 6 have the same structure. Taking the structure of one side of the crawling wheel assembly 8 as an example, the crawling wheel assembly 8 includes a first hydraulic cylinder 11, a slide 12, an elastic support rod 13, a parallel connecting rod 14, a deflection connecting rod 15, a vertical motor 16, a vertical roller 17, a transverse motor 18, and a transverse roller 19. The first hydraulic cylinder 11 is installed on the support carrier 6, and the output end of the first hydraulic cylinder 11 is connected to the slide 12. The slide 12 is slidably installed on the support carrier 6 along the transverse direction. The first hydraulic cylinder 11 can drive the slide 12 to move along the transverse direction.

[0032] The slide block 12 is connected to the middle of the parallel connecting rod 14 via an elastic support rod 13. Both ends of the parallel connecting rod 14 are connected to the support carrier 6 via two parallel deflection connecting rods 15. A vertical motor 16 and a horizontal motor 18 are mounted on the parallel connecting rod 14, and the vertical motor 16 and the horizontal motor 18 are respectively connected to a vertical roller 17 and a horizontal roller 19. When the first hydraulic cylinder 11 extends, the slide block 12 moves, and simultaneously, the elastic support rod 13 drives the deflection of the parallel connecting rod 14, causing the vertical roller 17 and the horizontal roller 19 to press tightly against the inner wall of the opening groove 3. Although the height of the monitoring component can be achieved through the friction between the rollers and the opening groove 3, when the monitoring component moves laterally, vertical balance is required via the vertical roller 17 to prevent the monitoring component from detaching from the opening groove 3. Of course, the force for lateral movement is achieved through the horizontal roller 19.

[0033] In this embodiment, the elastic support rod 13 includes an inner rod 20, an outer rod 21, a pin 22, and a first support spring 23. One end of the inner rod 20 is hinged to the slide block 12, and the other end of the inner rod 20 is slidably disposed inside the outer rod 21. The pin 22 is fixed to the outer side of one end of the inner rod 20, and the pin 22 is slidably disposed within a groove 24 formed on the outer rod 21. The two ends of the first support spring 23 are respectively connected to the inner rod 20 and the outer rod 21. By designing the elastic support rod 13, an elastic support effect can be achieved, ensuring the stability of the monitoring component during support and movement monitoring.

[0034] In this embodiment, a ranging component 25 is also installed on the support carrier 6. The ranging component 25 can indicate the position of the support carrier 6 relative to the bottom of the opening slot 3 to ensure monitoring effectiveness. The ranging component 25 includes a top rod 26, a bottom rod 27, a second support spring 28, a support roller 29, a roller seat 30, a trigger switch 31, and an indicator. The bottom rod 27 is fixed on the support carrier 6. The lower end of the top rod 26 is slidably disposed within the top rod 26. The bottom rod 27 and the top rod 26 are connected by the second support spring 28. The roller seat 30 is installed on the upper end of the top rod 26, and the support roller 29 is installed on the roller seat 30. The trigger switch 31 is installed in the middle of the inner side of the bottom rod 27. The trigger switch 31 is connected to the indicator and the power supply through a circuit. As the push rod 26 continues to move upward, it moves downward under the reaction force of the opening slot 3 to compress the second support spring 28. When the lower end of the push rod 26 contacts the trigger switch 31, a signal is sent to the indicator, indicating that the upward movement is complete and monitoring can begin.

[0035] In this embodiment, the connecting plate includes a first plate 32 and a second plate 33 that respectively cooperate with the first monitoring component 4 and the second monitoring component 5. The end of the first plate 32 away from the first monitoring component 4 is slidably installed in a slot opened inside the second plate 33. Both the first plate 32 and the second plate 33 have through holes for the output shaft of the linear motor 9 to pass through. Both the first plate 32 and the second plate 33 are equipped with elastic buffers. Due to the structural limitations of the fan-shaped cantilever beam itself, the relative position between the first monitoring component 4 and the second monitoring component 5 may change during monitoring. In this invention, a second hydraulic cylinder 45 is installed between the first plate 32 and the second plate 33, which can be used to actively control the distance between the first plate 32 and the second plate 33, that is, to control the relative position between the first monitoring component 4 and the second monitoring component 5 to adapt to the need for positional changes between adjacent structural beams.

[0036] In this embodiment, the elastic buffer includes a support plate 34, a central rod 35, a nut 36, a third support spring 37, and an elastic support leg 38. The support plate 34 is connected to the first plate 32. A through hole is provided on the support plate 34 for the central rod 35 to pass through. The upper end of the central rod 35 is connected to the nut 36, and the lower end of the central rod 35 is connected to the elastic support leg 38. The third support spring 37 connects the central rod 35 and the elastic support leg 38. By designing the elastic buffer, when the device is accidentally dropped, it can be cushioned to reduce damage. The length of the central rod 35 extending upward can be adjusted by the nut 36.

[0037] In this embodiment, the elastic support leg 38 includes a pressure plate 39, steel plate springs 40, a base plate 41, and an airbag 42. The pressure plate 39 is fixed to the lower end of the central rod 35. The base plate 41 is installed parallel to the lower side of the pressure plate 39. Multiple steel plate springs 40 are overlapped and installed between the pressure plate 39 and the base plate 41. The airbag 42 is installed on the outer side of the base plate 41. The airbag 42 is installed on the outer side of the base plate 41, which allows for easy replacement.

[0038] In this embodiment, the end of the support plate 34 is rotatably connected to the first plate 32 via a rotating rod 43, and a reset torsion spring 44 is installed between the support plate 34 and the first plate 32, thereby enabling the support plate 34 to twist and achieve a better support effect.
