TECHNICAL FIELD

[0001] The application belongs to the technical field of external wall insulation board, in particular to an external wall insulation board structure combined with aluminum formwork and a construction method thereof. BACKGROUND

[0002] With the rapid development of the construction industry, the requirements for building energy saving and environmental protection are increasingly strict. As one of the important means of building energy saving, the research and application of external wall insulation technology have attracted widespread attention. At present, external wall insulation technology mainly includes several forms such as external insulation board, internal insulation board and sandwich insulation wall. However, these traditional insulation methods have many problems in the construction process, such as long construction period, serious material waste and serious environmental pollution.

[0003] Specifically, the traditional external wall insulation construction method usually needs to install aluminum formwork first, and then remove the aluminum formwork after the concrete is poured and reaches a certain strength, and finally install the insulation board. This construction method has the following disadvantages: the installation, removal and installation of the aluminum formwork are carried out separately, which prolongs the construction period and affects the overall construction progress. Since the insulation board is installed after the removal of the aluminum formwork, gaps are easily generated, which leads to unstable insulation effect. The installation of the insulation board requires additional support and fixing measures, which increases the construction difficulty and cost. SUMMARY

[0004] The embodiments of the application provide an external wall insulation board structure combined with aluminum formwork and a construction method thereof, which solve the problems of separate installation of aluminum formwork and insulation board, which affects the construction progress, and unstable insulation effect.

[0017] As a preferred technical solution of the present application, the construction monitoring system comprises a piezoelectric vibration sensor array, which is bolted to the upper surface of the connecting blocks and the upper surface of the cross beam;

[0018] The abnormality identification module calculates the fractal dimension D value of the vibration signal in real time;

[0019] When the fractal dimension D value exceeds a preset threshold K, the adjusting member is triggered to retract.

[0020] As a preferred technical solution of the present application, the fractal dimension D value is obtained by the following steps:

[0022] b. Calculation of the correlation integral under different scales;

[0023] c. Determination of the slope in the double logarithmic coordinates by linear fitting, and the slope is the D value.

[0025] On the other hand, a construction method of an external wall insulation board structure combined with an aluminum formwork comprises the following steps:

[0026] S1, installing the aluminum formwork and the insulation board and fixing them through the connecting member;

[0027] S2, installing the outer frame and adjusting the distance between the cross beams;

[0028] S3, pouring concrete, and when the D value is greater than the threshold K, the pouring is paused and the adjusting member is automatically retracted, and after the fractal dimension D value is less than the threshold K, the pouring is resumed.

[0061] Specifically, the connecting piece 300 is fixed on the inside of the aluminum formwork 200 by the clamping block 301, so that the heat preservation plate 100 will not be displaced during the construction process, the connecting piece 300 forms a cavity between the heat preservation plate 100 and the aluminum formwork 200, the cavity is used for subsequent concrete pouring, the concrete is poured into the cavity and is in close contact with the heat preservation plate 100 and the aluminum formwork 200, and an integrated structure is formed, the design of the connecting piece 300 ensures the close combination between the heat preservation plate 100 and the concrete structure layer, and the stability and durability of the whole structure are improved.

[0062] In the embodiment of the present application, the adjusting part 403 comprises a cylinder 4031 and an adjusting rod 4032, the adjusting rod 4032 penetrates through the cylinder 4031 and is connected to the two cross beams 401 at both ends, the adjusting part 403 is installed between the two cross beams 401 through the connecting plate 402, the other end of the adjusting rod 4032 is provided with a threaded segment 4033, the thread angle of the threaded segment 4033 is 4°±0.2°, the pitch tolerance is ±0.02mm, the adjusting rod 4032 is screwed with the cylinder 4031 through the threaded segment 4033, and the use length of the adjusting rod 4032 can be adjusted through the design of the threaded segment 4033, so as to adjust the distance between the two cross beams 401. The adjusting rod 4032 penetrates through the cylinder 4031, is matched with the cylinder through the threaded segment 4033 at both ends, and the stepping motor drives the adjusting rod to rotate, so that the axial extension and contraction are realized.

[0063] Specifically, the outer frame 400 is arranged outside the thermal insulation board 100 and the aluminum formwork 200, mainly comprises two cross beams 401, a connecting plate 402 and an adjusting part 403, the adjusting part 403 is located between the two cross beams 401, and the connecting plate 402 is located between the adjusting part 403 and the cross beam 401, which plays a connecting and supporting role. The adjusting part 403 is composed of a cylinder 4031 and an adjusting rod 4032, and the length of the adjusting rod 4032 can be adjusted by rotating the adjusting rod 4032, so as to adjust the size and position of the outer frame 400 to adapt to different construction requirements and structural requirements. The left and right sides of the cylinder 4031 are both provided with connecting holes 4034 matched with the cross rod 304, which are used for connecting with the cross rod 304, further enhancing the stability and carrying capacity of the outer frame 400, and the outer sides of the thermal insulation board 100 and the aluminum formwork 200 are both provided with sleeves 101 and telescopic rods 102 to realize the connection with the outer frame 400.

[0064] Among them, the adjustment of the adjusting rod 4032: the stepping motor is installed at the outer side end of the adjusting part 403 and is connected with the adjusting rod 4032 through a shaft coupling, and the driving circuit is connected to the construction monitoring system 500. The construction monitoring system 500 sends a driving instruction to the stepping motor according to the trigger signal of the abnormality identification module 502, so as to realize the automatic retraction of the adjusting part 403. The adjusting rod 4032 and the threaded segment 4033 are designed in an integrated manner, and the stepping motor directly drives the adjusting rod 4032 to rotate. Since the threaded segment 4033 is matched with the thread on the inner wall of the cylinder 4031, the adjusting rod 4032 will move along the axial direction of the cylinder 4031 during rotation, so as to realize the axial extension and contraction, and further adjust the size and position of the outer frame 400;

[0065] When the fractal dimension D value exceeds the preset threshold K, the sound and light alarm is triggered, and a trigger signal is sent to the adjusting part 403 to make it retract, and the retraction amount of the stepping motor is calculated according to the following formula:

[0066] ΔL=k×(D-K)mm(D>K)

[0067] wherein k is an adjustment coefficient, which can be set as 2.5, for converting the part of the fractal dimension exceeding the threshold value into a suitable indentation amount to achieve effective adjustment of the structure, the adjustment member 403 is indented for 30s, the construction monitoring system 500 reacquires the vibration signal and calculates the fractal dimension D value, if the D value after retesting still exceeds the threshold value K, secondary indentation is performed, the secondary indentation amount is also calculated according to the above formula, it should be noted that the secondary indentation should be performed on the basis of the first indentation, that is, the total amount of the secondary indentation is the sum of the two calculated indentation amounts, in order to ensure the accuracy of the adjustment and the safety of the structure, the number of indentations is at most 3 times.

[0068] In the embodiment of the application, the construction monitoring system 500 comprises a piezoelectric vibration sensor array 501 fixed on the upper surface of the connecting block 302 and the upper surface of the beam 401 for real-time acquisition of the structural vibration signal, specifically, through calibration and debugging, it is ensured that the sensor can accurately capture the slight vibration change of the structure during the construction process;

[0069] The signal acquisition and processing unit is connected with the piezoelectric vibration sensor array 501, is responsible for receiving the vibration signal collected by the sensor, and pre-processes the signal, the piezoelectric vibration sensor array 501 continuously acquires the vibration signal at a frequency of 100Hz, the acquisition time is 10s each time, and the acquisition cycle interval is 1s, these parameters are determined according to the common vibration frequency range (10-50Hz) in the concrete pouring process and the short-term response characteristics of the structure in the pouring process, and the transient vibration characteristics of the structure in the concrete pouring process can be effectively captured, the signal is first filtered, the frequency band filtering technology is used to remove high-frequency noise and low-frequency interference in the signal, and the effective signal frequency band is retained, then the wavelet denoising algorithm is used for further denoising processing of the signal, the main characteristics of the signal are highlighted, finally the signal is normalized to adjust the signal amplitude to a range suitable for subsequent analysis, improve the quality and readability of the signal, and provide a reliable signal basis for subsequent fractal dimension calculation and anomaly identification;

[0070] The anomaly identification module 502 comprises a threshold value K comparator and an alarm, compares the calculated fractal dimension value with the preset threshold value K, the threshold value K is determined based on the pouring test to distinguish normal and abnormal vibration states, if the fractal dimension value exceeds the threshold value K, it is determined that the structure may be abnormal, the audible and light alarm is triggered, and a trigger signal is sent to the adjustment member 403 to make it perform the indentation action;

[0071] wherein the threshold value K is set according to the reference: for example, the threshold value K = 1.25 ± 0.05, through the test in the environment of 25℃, 30kN / m 2 static load + 10kN / m 2The 10-time pouring test calibration under the impact load, in the construction process, according to the real-time monitoring of the concrete pouring progress and the change of the structure response, the construction monitoring system 500 will periodically reevaluate and calibrate the threshold K to adapt to the dynamic change of the structure state, and ensure accurate identification of abnormal vibration conditions;

[0072] The abnormality identification module 502 includes a fractal dimension calculation unit 5021, which uses phase space reconstruction method (according to Takens theorem) to analyze the collected wavelet denoised vibration signals, extract feature parameters, and calculate fractal dimension. The specific steps are as follows:

[0073] The filtered vibration signal is reconstructed in phase space: the embedding dimension m and the delay time τ are determined, and the embedding dimension m and the delay time τ are determined according to the actual calculation condition. The one-dimensional time series vibration signal is converted into an m-dimensional phase space trajectory, and the phase space is reconstructed to reveal the internal dynamic characteristics of the signal;

[0074] Calculate the correlation integral C(r): in the reconstructed phase space, calculate the ratio of the number of all point pairs with a distance less than r to the total number of points, and obtain the correlation integral C(r), which reflects the distribution characteristics of the system at different scales;

[0075] Fitting the slope of the lnC(r)-lnr curve in the double logarithmic coordinate system to obtain the fractal dimension value D: taking lnr as the abscissa and lnC(r) as the ordinate to draw the curve, and linearly fitting the curve in the double logarithmic coordinate system. The slope of the fitting straight line is the fractal dimension value D, which is used to represent the degree of chaos of the system. The larger the D value is, the higher the degree of chaos of the system is;

[0076] Through the above steps, the fractal dimension value D can be calculated, which provides a key basis for subsequent anomaly identification. When the calculated D value exceeds the preset threshold K, it is determined that the structure may be abnormal, triggering the sound and light alarm, and sending a trigger signal to the adjusting part 403 to make it retract;

[0077] The cellular automaton simulation module 503 is used as an auxiliary analysis tool based on the known material creep prediction model, such as the Burgers model. According to the material properties and construction conditions, the creep process of the material is simulated, and the basic model is constructed. The material properties include elastic modulus, Poisson's ratio, compressive strength and other mechanical performance indicators. The construction conditions include concrete pouring speed, formwork support system stiffness, environmental temperature and humidity, etc. The elastic modulus is determined by material tensile test, the Poisson's ratio is determined according to the material type and reference to relevant standards, and the compressive strength is determined according to the concrete design strength grade. The concrete pouring speed is set according to the actual situation of the construction site, and the formwork support system stiffness is calculated by finite element analysis;

[0078] The multi-scale prediction module 504 performs evolution prediction based on the model of the cellular automaton simulation module 503. The multi-scale prediction module 504 includes a short-term prediction unit 5041 that predicts the structural state within 1 hour in the future based on the current vibration signal and the cellular automaton model, focusing on immediate changes and short-term trends.

[0079] The decision module 505 accesses a pre-stored treatment scheme library based on the prediction results. The treatment scheme library contains coping strategies for different prediction results. According to the time scale of the prediction, the type of the structure, and other information, the corresponding treatment scheme is matched. The multiple matched treatment schemes are screened and optimized. A detailed treatment scheme report is generated based on the effectiveness of the scheme, the implementation cost, the impact on the construction progress, and other factors. The report content includes the recommended coping strategy, the implementation steps, the expected effect, etc. The report is output to the construction personnel or the management personnel, providing a scientific basis for construction decision-making.

[0080] At the same time, an early warning mechanism is added. Based on historical data and simulation results, early warning thresholds for short-term, medium-term, and long-term creep prediction are set. Considering factors such as the safety factor of materials and the design allowable deformation, the early warning is divided into different levels, such as slight abnormality, moderate abnormality, and severe abnormality. Each level is configured with a corresponding treatment scheme. When the prediction result reaches or exceeds a certain early warning threshold, the system timely issues an early warning signal to remind the construction personnel to take corresponding measures to ensure construction safety.

[0081] When the prediction result reaches or exceeds a certain early warning threshold, the system timely issues an early warning signal to remind the construction personnel to take corresponding measures to ensure construction safety. The early warning levels are divided into slight abnormality, moderate abnormality, and severe abnormality. When there is slight abnormality, the construction personnel should increase the monitoring frequency, record the monitoring data every 30 minutes, and conduct preliminary inspection on the relevant construction area to analyze the abnormality reason. When there is moderate abnormality, the construction should be temporarily suspended, and the abnormal area should be inspected and evaluated in detail. According to the evaluation result, measures such as local reinforcement or adjustment of construction technology are taken, and the monitoring data is recorded every 10 minutes. When there is severe abnormality, the construction should be immediately stopped, the personnel should be quickly organized to evacuate the dangerous area, and the structure should be comprehensively inspected and evaluated. Reinforcement or repair measures are taken, and the construction should not continue until the problem is solved. At the same time, the monitoring data is recorded every minute to real-time master the structural state change.

[0082] The detailed content of the simulation performed by the cellular automaton simulation module 503 is as follows:

[0083] Step a, determine material properties and construction conditions, collect data of material mechanical properties, thermal properties, chemical composition, etc., determine construction environmental conditions such as temperature, humidity, load, etc., set the parameters of cellular automaton model, define the state of cell such as elasticity, plasticity, damage, etc., set the cell conversion rule, i.e. determine the state at next time based on the state of neighborhood and current state, determine the simulation parameters such as time step, spatial resolution, etc., build the model of simulating the evolution of material microstructure, simulate the creep behavior of material during construction and use by changing the construction condition parameters, calculate the evolution of material with time, during the simulation process, the material may experience elastic deformation, plastic deformation, damage accumulation, etc., and finally show the creep behavior, analyze the creep behavior of material such as creep rate, creep deformation, etc., evaluate the influence of construction conditions on the creep behavior of material, according to the simulation results, optimize the construction conditions or material design;

[0084] Step b, build EnKF framework, including state equation, observation equation, etc., generate initial parameter set representing the uncertainty of model parameters, collect real-time monitoring data such as strain, temperature, etc., compare monitoring data with model prediction data, calculate residual, update model parameters using EnKF algorithm to reduce residual, continuously apply EnKF algorithm during simulation process, continuously correct model parameters according to new monitoring data.
