Description

Technical Field

[0001] This invention relates to the field of building formwork technology, and in particular to a prefabricated titanium alloy formwork system with a self-drilling connection structure and its construction method. Background Technology

[0002] Prefabricated formwork is an important piece of construction equipment in building engineering. Its structural form and connection method directly affect the quality of concrete pouring and construction efficiency. Currently, building formwork mainly uses three categories: steel formwork, wooden formwork, and aluminum alloy formwork. Steel formwork has high strength but is heavy, requiring large machinery for handling and installation, resulting in high labor costs; wooden formwork is lightweight but has a limited number of uses, leading to significant resource waste; aluminum alloy formwork, while lightweight and reusable, is prone to electrochemical corrosion in humid environments, affecting its service life and concrete surface quality. Titanium alloy materials, due to their lightweight, high strength, strong corrosion resistance, and good compatibility with concrete, have begun to be explored for application in the field of building formwork in recent years. However, titanium alloy formwork still faces the following technical problems in practical applications: its connection process still uses the traditional bolt connection method, which requires drilling holes, aligning the holes, and then inserting bolts during construction. The process is cumbersome and seriously affects construction efficiency. At the same time, the tightness of the bolts depends on the worker's experience, and the connection status cannot be monitored in real time. Loosening can easily lead to grout leakage or over-tightening and damage to the formwork. Furthermore, there is a lack of on-site verification methods for abnormalities such as cavities and hard foreign objects inside the supporting structure, which often requires disassembly for inspection, which is time-consuming and labor-intensive. Summary of the Invention

[0003] Therefore, the present invention provides a prefabricated titanium alloy formwork system with a self-drilling connection structure and its construction method, in order to overcome the problems of low connection efficiency and lack of intelligent monitoring in the construction process of titanium alloy formwork in the prior art.

[0004] To achieve the above objectives, the present invention provides a construction method for an assembled titanium alloy formwork with a self-drilling connection structure, comprising: Step S1: Initially position and fix the titanium alloy template unit using an adjustable support frame, acquire template splicing images through a vision acquisition unit, extract template splicing seam width and misalignment, and determine whether the titanium alloy template meets the assembly benchmark. Step S2: When the assembly datum is not met, the laser three-dimensional ranging unit is activated to obtain the three-dimensional distance matrix from the datum acquisition point on the surface of each titanium alloy template unit to the construction datum surface. The template offset type is determined according to the deviation characteristics of the distance matrix, and the adjustable support frame is driven to complete the alignment correction. Step S3: When the assembly datum is met, the adjacent titanium alloy template units are locked and fixed using a self-drilling connection structure to complete the template assembly. Step S4: After the assembly is completed, the titanium alloy template is subjected to a vibration excitation with a preset amplitude through the excitation unit, and the template splicing image and three-dimensional distance data are continuously collected. The splicing seam fluctuation parameter is calculated based on the splicing image, and the template surface fluctuation parameter is calculated based on the three-dimensional distance data. Step S5: Based on the splice seam fluctuation parameter and the template surface fluctuation parameter, calculate the overall stability characterization value of the titanium alloy template, compare the stability characterization value with the preset stability threshold, and determine whether the titanium alloy template meets the stability standard. If it does not meet the standard, adjust the layout density of the self-drilling connection structure.

[0005] Furthermore, step S1 determines that the titanium alloy template meets the assembly datum based on the condition that the width of the template splice seam is within the preset width range and the misalignment is less than the preset misalignment threshold.

[0006] Furthermore, the alignment correction step in step S2 includes: Perform difference operations on the three-dimensional distance matrix to obtain the plane tilt deviation, normal offset deviation, and rotation angle deviation; Based on the type of the maximum deviation, the template is determined to be one of the following: tilt offset, normal advance / retreat offset, or angular offset. Output correction commands according to the offset type, and drive the adjustable support frame to perform the corresponding correction action.

[0007] Furthermore, the template assembly process in step S3 includes: Install self-drilling connection structures along the splicing seams at preset intervals; The self-drilling connection structure completes positioning, self-drilling, and self-locking in sequence.

[0008] Furthermore, in step S4, the splice seam fluctuation parameter is determined by the maximum fluctuation amplitude, average fluctuation amplitude, and fluctuation frequency of the splice seam width under vibration excitation.

[0009] Furthermore, in step S4, the template surface fluctuation parameter is determined by the maximum deviation of the three-dimensional distance between each reference acquisition point under vibration excitation, the root mean square deviation, and the in-plane flatness fluctuation value.

[0010] Furthermore, the stability characterization value in step S5 is jointly determined by the splice seam fluctuation parameter and the template surface fluctuation parameter.

[0011] Furthermore, in step S5, if the stability characterization value is less than the preset stability threshold, it is determined that the titanium alloy template does not meet the stability standard, and the layout density of the self-drilling connection structure is adjusted based on the difference between the stability characterization value and the preset stability threshold.

[0012] Furthermore, the density of the self-drilling connection structure is positively correlated with the stability difference, wherein the stability difference is the difference between the stability characterization value and the preset stability threshold.

[0013] The present invention also provides an assembled titanium alloy formwork system with a self-drilling connection structure, characterized in that it comprises: Several titanium alloy template units; An adjustable support frame is used for initial positioning and fixation of the titanium alloy template unit and for posture adjustment. The visual acquisition unit is used to acquire template splicing images to extract the splicing seam width and misalignment amount; The laser three-dimensional ranging unit is used to acquire three-dimensional distance data from the reference acquisition point on the surface of the titanium alloy template unit to the construction reference surface; The self-drilling connection structure is used to lock and fix adjacent titanium alloy template units; The vibration excitation unit is used to apply vibration excitation to the assembled titanium alloy template. The control unit is connected to the adjustable support frame, the vision acquisition unit, the laser three-dimensional ranging unit and the vibration excitation unit respectively, and is used to execute all the steps in the construction method according to any one of claims 1-9.

[0014] Compared with existing technologies, the advantages of this invention lie in its ability to acquire template splicing images in real time through a visual acquisition unit, extract the splicing seam width and misalignment, and automatically activate a laser three-dimensional ranging unit when assembly benchmarks are not met to obtain a three-dimensional distance matrix from the template surface benchmark acquisition point to the construction benchmark surface. By analyzing the deviation characteristics of the distance matrix, the type of template offset can be accurately determined, and the adjustable support frame can be driven to perform corresponding alignment correction actions. This closed-loop feedback control mechanism overcomes the shortcomings of low accuracy and low efficiency of traditional manual alignment, thus improving the template assembly accuracy.

[0015] Furthermore, after the template assembly is completed, the present invention applies vibration excitation of a preset amplitude through a vibration unit to simulate the dynamic loads that may be encountered during construction. Based on this, spliced ​​images and three-dimensional distance data are continuously acquired, and the splice seam fluctuation parameter and the template surface fluctuation parameter are calculated respectively. The present invention utilizes these two parameters to construct a quantitative evaluation index for template stability, realizing a post-evaluation of the connection quality of prefabricated templates and overcoming the deficiency of existing technologies that cannot effectively verify stability after construction.

[0016] Furthermore, this invention compares the calculated stability characterization value with a preset stability threshold. When the stability standard is not met, the density of the self-drilling connection structure is adaptively adjusted based on the difference between the stability characterization value and the preset stability threshold. Since the density and the stability difference are positively correlated, this invention changes the fixed-spacing layout method used in traditional construction. While ensuring structural safety, it avoids material waste caused by excessive layout, achieving optimized configuration and dynamic reinforcement of the connection structure.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0019] It should be noted that the data in this embodiment are all derived from a comprehensive analysis and evaluation of historical test data and corresponding historical test results from the three months prior to this test. Those skilled in the art will understand that the determination of the above-mentioned parameters for any single item in this invention can be achieved by selecting the value with the highest percentage based on the data distribution as the preset standard parameter, using weighted summation to obtain the value as the preset standard parameter, substituting each historical data point into a specific formula and using the value obtained from that formula as the preset standard parameter, or other selection methods, as long as the invention can clearly define different specific situations in the single-item judgment process through the obtained values.

[0020] Please see Figure 1 As shown, it is a flowchart of the construction method of the prefabricated titanium alloy formwork with a self-drilling connection structure according to an embodiment of the present invention; Step S1: Initially position and fix the titanium alloy template unit using an adjustable support frame, acquire template splicing images through a vision acquisition unit, extract template splicing seam width and misalignment, and determine whether the titanium alloy template meets the assembly benchmark. Step S2: When the assembly datum is not met, the laser three-dimensional ranging unit is activated to obtain the three-dimensional distance matrix from the datum acquisition point on the surface of each titanium alloy template unit to the construction datum surface. The template offset type is determined according to the deviation characteristics of the distance matrix, and the adjustable support frame is driven to complete the alignment correction. Step S3: When the assembly datum is met, the adjacent titanium alloy template units are locked and fixed using a self-drilling connection structure to complete the template assembly. Step S4: After the assembly is completed, the titanium alloy template is subjected to a vibration excitation with a preset amplitude through the excitation unit, and the template splicing image and three-dimensional distance data are continuously collected. The splicing seam fluctuation parameter is calculated based on the splicing image, and the template surface fluctuation parameter is calculated based on the three-dimensional distance data. Step S5: Based on the splice seam fluctuation parameter and the template surface fluctuation parameter, calculate the overall stability characterization value of the titanium alloy template, compare the stability characterization value with the preset stability threshold, and determine whether the titanium alloy template meets the stability standard. If it does not meet the standard, adjust the layout density of the self-drilling connection structure.

[0021] Specifically, step S1 determines that the titanium alloy template meets the assembly datum based on the condition that the template splice width is within the preset width range and the misalignment is less than the preset misalignment threshold; if the template splice width exceeds the preset width range or the misalignment is greater than or equal to the preset misalignment threshold, then the titanium alloy template does not meet the assembly datum.

[0022] In this embodiment of the invention, the preset width range is 2mm to 5mm, and the preset misalignment threshold is 2mm. However, the above values ​​are not limited to these, and those skilled in the art can adjust the above values ​​according to actual needs.

[0023] Specifically, the vision acquisition unit uses an industrial camera to extract the edge features of the splicing seam through image recognition algorithms, and calculates the seam width and misalignment.

[0024] Specifically, the alignment correction step in step S2 includes: Perform difference operations on the three-dimensional distance matrix to obtain the plane tilt deviation, normal offset deviation, and rotation angle deviation; Based on the type of the maximum deviation, the template is determined to be one of the following: tilt offset, normal advance / retreat offset, or angular offset. Output correction commands according to the offset type, and drive the adjustable support frame to perform the corresponding correction action.

[0025] Specifically, the measured coordinates of each reference acquisition point are compared with the theoretical coordinates point by point to obtain the deviation matrix; the deviation values ​​are linearly fitted along the length and width directions of the template; if the Z-direction deviation shows a linear trend, it is extracted as the plane tilt deviation; if the Z-direction deviations of all acquisition points are similar in magnitude and have the same sign, their average value is taken as the normal offset deviation; if the X-direction or Y-direction deviations of two sets of acquisition points along the diagonal direction are opposite, the torsional angle around the Z-axis is calculated as the rotation angle deviation.

[0026] Specifically, if a tilt deviation is detected, the support rod on the lower side is extended or the support rod on the higher side is retracted according to the tilt direction until the tilt angle is less than a preset threshold. If a normal deviation is detected, all support rods are controlled to move synchronously in the normal direction, so that the template as a whole moves to the theoretical position. If an angular deviation is detected, the two sets of support rods in the diagonal direction are controlled to move differentially, so that the template rotates around the center to the correct angle. During the correction process, the laser three-dimensional ranging unit continuously monitors the template position in real time, forming a closed-loop feedback control until all deviation values ​​are less than the preset threshold.

[0027] Specifically, the laser three-dimensional ranging unit is a high-precision laser ranging sensor based on phase or pulse principle, combined with a two-dimensional galvanometer scanning mechanism or mechanical rotating stage, and is installed on an independent and stable reference support. Its measurement field of view covers the entire assembly area of ​​the titanium alloy template unit.

[0028] Specifically, the template assembly process in step S3 includes: Install self-drilling connection structures along the splicing seams at preset intervals; The self-drilling connection structure completes positioning, self-drilling, and self-locking in sequence.

[0029] In this embodiment of the invention, the preset spacing ranges from 200mm to 300mm, but the above value is not limited to this. Those skilled in the art can adjust the above value according to actual needs.

[0030] Specifically, in step S4, the splice seam fluctuation parameter is determined by the maximum fluctuation amplitude, average fluctuation amplitude, and fluctuation frequency of the splice seam width under vibration excitation. The splice seam fluctuation parameter is calculated using the following formula: In the formula, For the splice seam fluctuation parameter, This represents the maximum fluctuation amplitude during the vibration process. This represents the average fluctuation amplitude during the vibration process. This is the allowable deviation threshold for the width of the splice seam. This represents the measured dominant frequency of the fluctuation. The excitation frequency of the excitation unit is... These are the weighting coefficients.

[0031] In this embodiment of the invention, The value is 2.0 mm. The value is set to 20Hz. The value is 0.4. The value is 0.3. The value is 0.3, but the above value is not limited to this. Those skilled in the art can adjust the above value according to actual needs.

[0032] Specifically, the excitation unit is an electric or hydraulic vibrator, fixedly installed on the surface of the assembled titanium alloy template unit or on the crossbeam of the adjustable support frame, and its output end is rigidly connected to the template surface through a connector. The excitation unit has a built-in signal generator and power amplifier, which can receive commands from the control unit and output a sine wave or random wave vibration excitation with a preset frequency and preset amplitude. During operation, the excitation unit applies a continuous and stable excitation force to the template system, causing the template to produce controllable micro-amplitude vibrations to simulate dynamic loads such as concrete pouring, vibration, or construction disturbance. In this embodiment of the invention, the preset amplitude is 0.5mm to 1.0mm, and the preset frequency is 20Hz.

[0033] Specifically, in step S4, the template surface fluctuation parameter is determined by the maximum deviation of the three-dimensional distance between each reference acquisition point under vibration excitation, the root mean square deviation, and the in-plane flatness fluctuation value. The template surface fluctuation parameter is calculated using the following formula: In the formula, For template surface fluctuation parameters, The maximum normal displacement deviation at the measuring point. This is the root mean square value of the displacement deviation at the measuring point. This refers to the allowable thickness deviation of the template surface. This represents the in-plane flatness fluctuation value. These are the weighting coefficients.

[0034] In this embodiment of the invention, the in-plane flatness fluctuation value is the difference between the maximum and minimum values ​​of the normal displacement relative to the initial reference plane. The value is 5mm. The value is 0.4. The value is 0.3. The value is 0.3, but the above value is not limited to this. Those skilled in the art can adjust the above value according to actual needs.

[0035] Specifically, the stability characterization value in step S5 is determined jointly by the splice seam fluctuation parameter and the template surface fluctuation parameter. The stability characterization value is calculated using the following formula: In the formula, This is a stability characterization value. This is the weighting coefficient for seam fluctuation. This is the template surface fluctuation weighting coefficient.

[0036] In this embodiment of the invention, The value is 0.6. The value is 0.4, but the above value is not limited to this. Those skilled in the art can adjust the above value according to actual needs.

[0037] Please see Figure 2 As shown, it is a flowchart of an embodiment of the present invention for determining whether a titanium alloy template meets the stability standard based on the stability characterization value; Specifically, in step S5, if the stability characterization value is less than the preset stability threshold, the titanium alloy template is determined to not meet the stability standard, and the layout density of the self-drilling connection structure is adjusted based on the difference between the stability characterization value and the preset stability threshold; if the stability characterization value is greater than or equal to the preset stability threshold, the titanium alloy template is determined to meet the stability standard.

[0038] In this embodiment of the invention, the preset stability threshold is 0.9, but this value is not limited to this. Those skilled in the art can adjust this value according to actual needs.

[0039] Specifically, the density of self-drilling connection structures is positively correlated with the stability difference. If the stability difference is less than the first preset difference, then the deployment density is determined to be the first preset density; If the stability difference is greater than or equal to the first preset difference and less than the second preset difference, then the deployment density is determined to be the second preset density. If the stability difference is greater than or equal to the second preset difference, then the deployment density is determined to be the third preset density; The stability difference is the difference between the stability characterization value and the preset stability threshold.

[0040] In this embodiment of the invention, the first preset difference is 0.1, the second preset difference is 0.2, the first preset density is 300mm between adjacent self-drilling connection structures, the second preset density is 200mm between adjacent self-drilling connection structures, and the third preset density is 100mm between adjacent self-drilling connection structures. However, the above values ​​are not limited to these, and those skilled in the art can adjust the above values ​​according to actual needs.

[0041] Please see Figure 3 As shown, it is a schematic diagram of the module connection of the assembled titanium alloy template system with self-drilling connection structure according to an embodiment of the present invention; The present invention provides an assembled titanium alloy formwork system with a self-drilling connection structure, comprising: Several titanium alloy template units; An adjustable support frame is used for initial positioning and fixation of the titanium alloy template unit and for posture adjustment. The visual acquisition unit is used to acquire template splicing images to extract the splicing seam width and misalignment amount; The laser three-dimensional ranging unit is used to acquire three-dimensional distance data from the reference acquisition point on the surface of the titanium alloy template unit to the construction reference surface; The self-drilling connection structure is used to lock and fix adjacent titanium alloy template units; The vibration excitation unit is used to apply vibration excitation to the assembled titanium alloy template. The control unit is connected to the adjustable support frame, the vision acquisition unit, the laser three-dimensional ranging unit and the vibration excitation unit respectively, and is used to execute all the steps in the construction method according to any one of claims 1-9.

[0042] Specifically, the self-drilling connection structure is a self-drilling screw, with a drill head at the front end and a threaded shank at the rear end. During the locking process, after the self-drilling screw is positioned at a preset location, the drill head first drills a hole in the surface of the titanium alloy template by means of an electric tightening gun. Then, the threaded shank is screwed into the hole and pressed to form an internal thread, thereby achieving self-locking between adjacent titanium alloy template units.

[0043] Understandably, the adjustment of the self-drilling connection structure layout density is based on feedback from the control unit, and secondary reinforcement is carried out in the construction area or in assembled areas that are determined not to meet stability standards. Specifically, the control unit dynamically calculates a new target spacing based on the level of stability difference and outputs instructions to the operators through an interactive interface. According to the instructions, the operators add new self-drilling screws between existing screws at the predetermined splice joints of adjacent templates, shortening the actual connection spacing from the initial sparse state to a denser state. This increases the number of constraint points per unit length, thereby improving the overall connection stiffness and stability of the template system and achieving adaptive adjustment of the layout density.
