Description

Technical Field

[0001] This invention relates to the field of concrete construction, and in particular to a device and method for monitoring deformation of large-volume concrete with high formwork. Background Technology

[0002] The combined construction of large-volume concrete and high formwork is a common construction technique for large-span, heavy-load building structures. High formwork systems are characterized by large erection height, wide span, concentrated loads, and complex stress states, while large-volume concrete pouring involves large volume, long operation time, high heat of hydration, and drastic dynamic changes in construction loads. The combination of these two factors significantly increases the difficulty of safety control of the support system.

[0003] Existing monitoring methods for high-formwork structures mainly rely on manual inspections and simple tools such as levels and theodolites, which suffer from low efficiency, discrete data, and inability to provide real-time continuous monitoring. Some automated monitoring devices can only measure displacement in a single direction and cannot simultaneously acquire three-dimensional deformation data such as vertical settlement, horizontal displacement, and tilt angle of the uprights, resulting in incomplete, delayed, and inaccurate monitoring data. The devices are often installed using simple binding or clamping methods, which are prone to displacement and loosening under construction vibration, leading to drift in the measurement benchmark. At the same time, they lack anti-interference algorithms and data processing mechanisms, making them susceptible to environmental noise such as concrete vibration and wind loads, resulting in a high false alarm rate and failing to meet the actual needs of automated and high-precision safety management in high-formwork construction. Summary of the Invention

[0004] To address the above problems, this invention proposes a deformation monitoring device and method for high-formwork construction of large-volume concrete, which solves the problem that traditional monitoring methods cannot acquire three-dimensional deformation data such as horizontal displacement and vertical settlement of high-formwork uprights in all aspects in real time during high-formwork construction.

[0005] This application proposes a deformation monitoring device for large-volume concrete with high formwork, comprising: The high formwork support is composed of multiple horizontal bars, vertical bars and vertical bars connected in an alternating manner; Multiple multi-angle detection components are vertically arranged and installed on multiple longitudinal bars. The multi-angle detection components are equipped with a height laser rangefinder in the height direction to detect height deformation, and a circumferential laser rangefinder in the horizontal direction to detect lateral and longitudinal deformation by rotating in the horizontal plane. Multiple reflectors are installed around the multi-angle detection assembly. The reflectors are divided into lateral reflectors and longitudinal reflectors, which are fixed on the vertical rod and the upright rod, respectively, and are used to detect lateral and longitudinal displacement. Both the lateral reflectors and the longitudinal reflectors are oriented towards the multi-angle detection assembly. The data processing terminal receives electrical signals from the multi-angle detection component, processes the signals, and issues alarms.

[0006] Furthermore, the multi-angle detection component includes a first clamping ring, a main support rod, a branch rod, a motor, and a height measuring target. The first clamping ring is clamped around the outside of the longitudinal rod. The motor is installed below the first clamping ring. The main support rod is installed vertically downward below the motor and rotates under the control of the motor. The branch rod is perpendicular to the main support rod and fixed to the main support rod. The height laser rangefinder is installed at the end of the main support rod, and the circumferential laser rangefinder is installed at the end of the branch rod. The altitude measuring target is installed above the first clamping ring, and the reflection direction of the altitude measuring target is vertically upward, opposite to the altitude laser rangefinder of the adjacent multi-angle detection component.

[0007] Furthermore, the lateral reflector includes a second clamping ring, a connecting rod, and a lateral ranging target. The second clamping ring is clamped around the outside of the longitudinal rod, and the lateral ranging target is installed below the second clamping ring via the connecting rod. The reflection direction of the lateral ranging target is in the horizontal plane.

[0008] Furthermore, the longitudinal reflector includes a third clamping ring and a longitudinal ranging target. The third clamping ring is clamped to the outside of the upright. The two longitudinal ranging targets are respectively installed on the front and rear sides of the third clamping ring. The reflection direction of the longitudinal ranging target is perpendicular to the direction of the transverse ranging target.

[0009] Furthermore, positioning holes are provided on the longitudinal rod and the upright rod, and positioning pins are installed on the inner walls of the first clamping ring, the second clamping ring and the third clamping ring, and the positioning pins are inserted into the positioning holes.

[0010] Furthermore, the surfaces of the lateral ranging target, the longitudinal ranging target, and the altitude ranging target are all coated with an anti-ultraviolet high-reflectivity coating.

[0011] Furthermore, the lateral ranging targets and the longitudinal ranging targets of each layer are located on the same horizontal plane.

[0012] A method for detecting deformation of large-volume concrete with high formwork, employing a large-volume concrete high formwork deformation monitoring device, includes the following steps: Installation and positioning: Fix multiple multi-angle detection components and reflectors onto the high formwork support; Zero-point calibration: The data processing terminal collects initial distance data and establishes a monitoring reference coordinate system; Real-time monitoring: The height laser rangefinder continuously collects vertical displacement data, while the circumferential laser rangefinder rotates in steps at a set angle, sequentially collecting horizontal and vertical displacement data from the lateral and longitudinal reflectors. Data processing: The data processing terminal calculates the tilt angle and overall deformation of the pole based on the vertical settlement, lateral displacement, and longitudinal displacement; Early warning judgment: The calculation result is compared with the set threshold. If the result exceeds the set threshold, an audible and visual alarm signal is immediately output.

[0013] Furthermore, during installation and positioning, the angles of the multi-angle detection component and the reflector are adjusted to appropriate positions, and the positioning pin is tightened.

[0014] Furthermore, before data processing, the vertical settlement, lateral displacement, and longitudinal displacement data from a single measurement are filtered and averaged after multiple samplings.

[0015] The beneficial effects of this invention are as follows: Three-dimensional synchronous monitoring: By combining the height laser rangefinder and the circumferential laser rangefinder, vertical settlement, lateral displacement and longitudinal displacement are measured simultaneously, which completely restores the three-dimensional deformation state of the frame and solves the problem of incomplete monitoring data. Strong anti-interference capability: By adopting a stepping rotation, fixed-point dwell, and multiple measurement and averaging method, noise interference from concrete vibration, wind load, etc. is effectively filtered out, improving data accuracy and reliability; High degree of automation: No human intervention is required; it can continuously monitor in real time 24 hours a day; data is automatically processed, calculated, and alerted, eliminating blind spots and lag in manual monitoring. Easy and versatile installation: Modular structure, quick assembly and disassembly, suitable for high formwork systems with different pipe diameters and heights, with strong versatility.

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. All other implementations obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. In the various drawings, the same elements are represented by the same or similar reference numerals, and for clarity, the various parts in the drawings are not drawn to scale.

[0019] See Figure 1-7As shown, this application proposes a deformation monitoring device for high-formwork of large-volume concrete, comprising: a high-formwork support 1, which is formed by multiple horizontal bars 11, vertical bars 12 and uprights 13 connected in an alternating manner; multiple multi-angle detection components 2, which are installed on the vertical bars 12, wherein a height laser rangefinder 25 is installed in the height direction to detect height deformation, and a circumferential laser rangefinder 26 is installed in the horizontal direction to detect lateral and longitudinal deformation by rotating in the horizontal plane; multiple reflectors 3, which are installed around the multi-angle detection components 2, wherein the reflectors 3 are divided into lateral reflectors 31 and longitudinal reflectors 32, which are fixed on the vertical bars 12 and the uprights 13 respectively, for detecting lateral and longitudinal displacement, and both the lateral reflectors 31 and the vertical reflectors 32 are oriented towards the multi-angle detection components 2 in the same plane; and a data processing terminal, which receives electrical signals from the multi-angle detection components 2, processes the signals, and issues alarms. In this embodiment, multiple multi-angle detection components 2 are aligned vertically. The height laser rangefinder 25 of the upper multi-angle detection component 2 receives the vertical settlement information from the lower multi-angle detection component 2. Each multi-angle detection component 2 has a lateral reflector 31 installed on both sides and a longitudinal reflector 32 installed on both sides. The circumferential laser rangefinder 26 of the multi-angle detection component 2 rotates 360° to sequentially receive the displacement information from the surrounding lateral and longitudinal reflectors 31. The detection data from the height laser rangefinder 25 and the circumferential laser rangefinder 26 are synchronously transmitted to the data processing terminal. The data processing terminal compares the real-time detected displacement data with a preset safety threshold. When the displacement data in a certain direction exceeds the preset threshold, an alarm is immediately triggered, facilitating timely investigation of potential deformation hazards in high formwork structures by construction personnel.

[0020] See Figure 3-4 As shown, specifically, the multi-angle detection component 2 includes a first clamping ring 21, a main support rod 22, a branch rod 23, a motor 24, and a height measuring target 27. The first clamping ring 21 is clamped around the outside of the longitudinal rod 12. The motor 24 is installed below the first clamping ring 21. The main support rod 22 is installed vertically downward below the motor 24 and rotates under the control of the motor 24. The branch rod 23 is perpendicular to the main support rod 22 and fixed on the main support rod 22. The height laser rangefinder 35 is installed at the end of the main support rod 22, and the circumferential laser rangefinder 36 is installed at the end of the branch rod 23. The height measuring target 27 is installed above the first clamping ring 21, and the reflection direction of the height measuring target 27 is vertically upward, opposite to the height laser rangefinder 25 of the adjacent multi-angle detection component 2.

[0021] In this embodiment, the first clamping ring 21 consists of two semi-rings connected by bolts, with the upper and lower rings fastened to the outside of the longitudinal rod 12. The main support rod 22 is vertically downward, with its upper end connected to the first clamping ring 21 via the motor 24, and its lower end equipped with the height laser rangefinder 25. A height measuring target 27 is installed above the first clamping ring 21. Between the adjacent multi-angle detection components 2, the upper-layer height laser rangefinder 25 faces the lower-layer height measuring target 27, receiving height reflection information from the lower layer to detect height deformation at that location. When the motor 24 is started, it can drive the main support rod 22 to rotate, and the branch rod 23 drives the circumferential laser rangefinder 26 to rotate synchronously in the horizontal plane. The orientation of the circumferential laser rangefinder 26 is adjusted according to the installation positions of the surrounding lateral reflectors 31 and longitudinal reflectors 32 to ensure it is aligned with a preset position, thus completing the detection of lateral and longitudinal deformation.

[0022] See Figure 5 , 6 As shown, specifically, the lateral reflector 31 includes a second clamping ring 311, a connecting rod 312, and a lateral ranging target 313. The second clamping ring 311 is clamped around the outside of the vertical rod 12, and the lateral ranging target 313 is installed below the second clamping ring 311 via the connecting rod 312. The reflection direction of the lateral ranging target 313 is in the horizontal plane. Specifically, the longitudinal reflector 32 includes a third clamping ring 321 and a longitudinal ranging target 322. The third clamping ring 321 is clamped around the outside of the vertical rod 13, and the two longitudinal ranging targets 322 are respectively installed on the front and rear sides of the third clamping ring 321. The reflection direction of the longitudinal ranging target 322 is perpendicular to the direction of the lateral ranging target 313. Specifically, the lateral ranging targets 313 and the longitudinal ranging targets 322 of each layer are located on the same horizontal plane. In this embodiment, the second clamping ring 311 and the third clamping ring 312 have the same structure, each consisting of two half-rings connected by bolts, respectively clamping the outer sides of the longitudinal rod 12 and the upright rod 13; the connecting rod 312 extends downward a certain distance, and the lateral ranging target 313 and the longitudinal ranging target 322 are installed on the same horizontal plane; the corresponding targets are aligned with the lateral and longitudinal detection directions of the circumferential laser rangefinder 26, thereby ensuring that the circumferential laser rangefinder 26 can accurately receive reflection information from both directions when rotated to the corresponding orientation. Two lateral reflectors 31 and two longitudinal reflectors 32 are installed around the perimeter of each multi-angle detection component 2.

[0023] See Figure 4-7As shown, specifically, positioning holes 14 are provided on the longitudinal rod 12 and the upright rod 13. Positioning pins 4 are installed on the inner walls of the first clamping ring 21, the second clamping ring 311, and the third clamping ring 321. The positioning pins 4 are inserted into the positioning holes 14 to fix the multi-angle detection component 2, the lateral reflector 31, and the longitudinal reflector 32. Specifically, the surfaces of the lateral ranging target 313, the longitudinal ranging target 322, and the altitude ranging target 27 are all coated with an anti-ultraviolet high-reflection coating. In this embodiment, the first clamping ring 21, the second clamping ring 311, and the third clamping ring 321 are all formed by two semi-ring structures enclosing each other. The positioning pin 4 is provided on the inner wall of the first clamping ring 21, the second clamping ring 311, and the third clamping ring 321. The positioning pin 4 is inserted into the positioning hole 14 of the longitudinal rod 12 and the upright rod 13 to determine the installation position of the multi-angle detection component 2, the lateral reflector 31, and the longitudinal reflector 32, and to ensure that the components do not shift or loosen under construction vibration and impact. Preferably, the inner wall of the first clamping ring 21, the second clamping ring 311, and the third clamping ring 321 is equipped with a rubber anti-slip pad, which plays a role in buffering and increasing friction, and ensures the stability of the long-term measurement benchmark.

[0024] See Figure 1 , 3 As shown, a method for detecting deformation of large-volume concrete with high formwork uses a large-volume concrete high formwork deformation monitoring device and includes the following steps: S001. Installation and positioning: Fix multiple multi-angle detection components and reflectors onto the high formwork support; S002, Zero point calibration: The data processing terminal collects initial distance data and establishes a monitoring reference coordinate system; S003. Real-time monitoring: The height laser rangefinder continuously collects vertical displacement data, and the circumferential laser rangefinder rotates step by step at a set angle to collect horizontal and vertical displacement data of the transverse and longitudinal reflectors in sequence. S004. Data Processing: The data processing terminal calculates the tilt angle and overall deformation of the pole based on the vertical settlement, lateral displacement, and longitudinal displacement. S005, Early Warning Judgment: Compare the calculation result with the set threshold. If the result exceeds the set threshold, immediately output an audible and visual alarm signal.

[0025] Specifically, during the installation and positioning of S001, the angles of the multi-angle detection component 2 and the reflector 3 are adjusted to appropriate positions, and the positioning pin 4 is tightened.

[0026] Specifically, before processing the S004 data, the vertical settlement, lateral displacement, and longitudinal displacement data from a single measurement are filtered and averaged after multiple samplings.

[0027] The detection method of this application is as follows: adjacent multi-angle detection components transmit reflection information to each other in the height direction to calculate height settlement; the multi-angle detection components rotate in the horizontal plane, and adjacent lateral reflectors reflect lateral distance information to the circumferential laser rangefinder of the multi-angle detection components to calculate lateral displacement; adjacent longitudinal reflectors reflect longitudinal distance information to the circumferential laser rangefinder of the multi-angle detection components to calculate longitudinal displacement; the high formwork support is divided into multiple coordinate systems with the multiple multi-angle detection components as the center, and the deformation in each coordinate system can be detected individually.

[0028] The beneficial effects of this invention are as follows: Three-dimensional synchronous monitoring: By combining the height laser rangefinder and the circumferential laser rangefinder, vertical settlement, lateral displacement and longitudinal displacement are measured simultaneously, which completely restores the three-dimensional deformation state of the frame and solves the problem of incomplete monitoring data. Strong anti-interference capability: By adopting a stepping rotation, fixed-point dwell, and multiple measurement and averaging method, noise interference from concrete vibration, wind load, etc. is effectively filtered out, improving data accuracy and reliability; High degree of automation: No human intervention is required; it can continuously monitor in real time 24 hours a day; data is automatically processed, calculated, and alerted, eliminating blind spots and lag in manual monitoring. Easy and versatile installation: Modular structure, quick assembly and disassembly, suitable for high formwork systems with different pipe diameters and heights, with strong versatility.
