Description

Technical Field

[0001] The present invention belongs to the technical field of building construction. Specifically, it relates to a protective tool and construction method for a detachable and reusable steel structure roof. Background Art

[0002] Currently, the edge protection of conventional steel structure roofs generally uses steel pipe fasteners to set up protective frames. There are the following problems with this method: 1) Difficult to fix the vertical poles: Since steel structures are mostly frame structures and the roofs are mostly color steel plate roofs, when fixing the protective columns on the roof, the protective columns are mostly fixed by welding. This method has high requirements for operators, and welding is likely to cause damage to steel structure components, affecting the construction quality; 2) Low construction efficiency: Conventional steel pipe fastener protection uses fasteners to connect and fix steel pipes. Both the installation and removal work are relatively complex, resulting in low construction efficiency; 3) Non-standardized construction with poor appearance: Steel pipe fastener guardrails mostly use leftover materials in construction, and during the construction process, construction workers cannot ensure the straightness of their construction, so the appearance is poor. Therefore, a protective tool and construction method for a detachable and reusable steel structure roof are designed. Summary of the Invention

[0003] The embodiments of the present invention provide a protective tool and construction method for a detachable and reusable steel structure roof, which solve the problems of difficult fixation of the safety protection steel pipes at the edges of traditional steel structure roofs, insecure fixation of the edge protection, and the welding of the edge protection steel pipes to the steel structure affecting the quality of the steel structure.

[0004] In view of the above problems, the technical solution proposed by the present invention is as follows:

[0005] The present invention provides a protective tool for a detachable and reusable steel structure roof, including a protective plate and columns. The protective plate includes a plurality of protective sheets.

The mounting post is fixed at the bottom end of the telescopic rod, the spring B is wound around the outside of the telescopic rod, the adjusting rod is arranged at the other end of the telescopic rod, and the sleeve is sleeved on the outside of the spring B.

[0009] As a preferred technical solution of the present invention, it further includes a safety prompt system. The safety prompt system is used to monitor the use of protective tools and give safety prompts when problems occur. The safety prompt system includes a sensor acquisition module, an Internet of Things sensor network, a data analysis module, a safety assessment module and a safety prompt module;

[0010] The sensor acquisition module uses sensors to monitor the protective tools and the construction environment;

[0015] As a preferred technical solution of the present invention, the data analysis module uses self-organizing mapping technology to analyze data, specifically including the following steps:

[0016] Step 1, define the fault data, including the characteristics, thresholds and conditions of the fault, create a two-dimensional grid, assign a random weight vector to each node, select a sample from the data, and use the Euclidean distance to measure the weight vector with high similarity to the sample to obtain the winning node;

[0018] Step 3, map all the data into the two-dimensional grid, record the winning nodes of each data, and observe the clustering pattern on the two-dimensional grid. Abnormal clustering indicates data faults;

[0019] Step 4: Calculate the distance between each sample and the weight vector of the winning node. An abnormally large distance indicates that the sample is an outlier. Analyze the impact of each feature on the node weight to determine which feature causes the fault, and use the visualization of a two-dimensional grid to identify patterns and unexpected behaviors in the data.

[0020] As a preferred technical solution of the present invention, the security assessment module uses the Monte Carlo simulation technique to perform a security assessment on the data. The specific steps are as follows:

[0021] Step a: Determine the fail-safe level for evaluating the analysis result of the data analysis module, establish a mathematical model, and select a suitable probability distribution for the uncertainty parameters in the mathematical model.

[0022] Step b: Use a random number generator to generate random samples that conform to the parameter distribution, and substitute the generated random samples into the data model to obtain the calculation results.

[0023] Step c: Perform a probability distribution on the calculation results, represent them using a probability density function or a cumulative distribution function, calculate the risk metric, and compare the obtained risk metric with the predefined safety level standard to evaluate the safety level of the fault data.

[0024] Step d: Perform a sensitivity analysis on the parameters to determine which parameters have the greatest impact on the model output, and optimize the model.

[0025] As a preferred technical solution of the present invention, a motor is provided inside the motor box. The output end of the motor is in transmission connection with the rotating rod. The rotating rod is screwed to the connecting column. The other end of the rotating rod is rotatably connected to a fixed block. The connecting plate includes two mounting plates and several connecting plates. The end of the connecting plate is provided with a connecting end, and adjacent connecting plates are rotatably connected through the connecting end. The mounting plates are arranged on the uppermost and lowermost connecting plates, and the connecting plates are designed in an arc shape.

[0026] As a preferred technical solution of the present invention, insertion rods are fixed to both the fixed block and the bottom of the motor box. An installation hole that is threadedly matched with the threaded column is opened at the upper end of the column. The elastic piece is designed in a cross shape, and a jack that is adapted to the insertion rod is opened at the center of the elastic piece. A spring A is arranged below the elastic piece, and both ends of the spring A are fixedly connected to the connecting column. An insertion cavity is arranged inside the threaded column.

[0027] As a preferred technical solution of the present invention, the mounting post is screwed to the protective plate. Damping washers are provided at both ends of the spring B. The damping washers are arranged outside the telescopic rod and are in threaded cooperation with the telescopic rod. One end of the adjusting rod is in threaded cooperation with the telescopic rod, and the other end of the adjusting rod is in threaded cooperation with a connecting block.

[0028] On the other hand, a construction method of a protective tool for a detachable and reusable steel structure roof includes the following steps:

[0029] S1. Fix the columns on both sides of the area to be protected. Fix the threaded columns on the columns through the mounting holes at the upper ends of the columns. Select a protective plate with a suitable size, and insert the fixing blocks and the insertion rods at the bottom of the motor box into the connecting columns and the threaded columns.

[0030] S2. Use a remote control to control the motor to synchronously rotate the rotating rod and the connecting column, and unfold the protective plate.

[0031] S3. After the protective plate is unfolded, adjust the positions of the adjusting rod and the connecting block according to the situation of the building surface, and connect the bottom of the protective plate to the connecting components of the building surface for protection.

[0032] S4. During the protection process, use sensors to monitor the protective plate and its surrounding environment, analyze the monitoring data through the safety prompt system, and conduct a safety assessment. When problems occur, give prompts.

[0033] S5. When disassembly is required, first untie the fixing parts, then control the motor to wind up the protective plate, and finally pull out the winding structure.

[0034] Compared with the prior art, the beneficial effects of the present invention are:

Each protective piece can rotate around the hinge axis when being wound up, so as to achieve folding, allowing the protective piece to be folded into a smaller volume when not needed, realizing the compact storage of the protective plate and saving space.

[0036] (2) The data collected by the sensors of the present invention is transmitted to the data analysis module through the Internet of Things sensor network. Technologies such as self-organizing mapping are used to analyze the data, identify abnormal patterns, evaluate the safety level of the analysis results, and issue early warnings to construction workers through the safety prompt module, improving the accuracy and efficiency of system fault diagnosis and construction safety.

[0037] (3) Through the design of the reinforcement structure, the present invention utilizes the acting force of the spring to reinforce the bottom of the protection plate, improving the reliability of the protection plate under harsh weather conditions. Especially during the construction of high-rise buildings, the effect of wind force may have a greater impact on the protection plate, enhancing the stability of the protection.

[0060] Referring to the attached Figures 1-8 As shown, the present invention provides a technical solution: a protective tool for a detachable and reusable steel structure roof, including a protective plate 100 and a column 400. The protective plate 100 includes a plurality of protective sheets. The upper end of the protective sheet is provided with a hook portion, and the lower end of the protective sheet is a notch adapted to the hook portion. Adjacent protective sheets are hooked together through the hook portion and the notch, and a movable hinge is provided between adjacent protective sheets for firmness. When winding up, the hinge can be folded, so as not to affect the winding-up work of the protective sheet;

[0061] A winding-up structure 200, the winding-up structure 200 is arranged at the upper end of the protective plate 100. The winding-up structure 200 includes a connecting column 201, a motor box 202, a connecting plate and a rotating rod 207. The motor box 202 is arranged at one end of the connecting rod. The connecting column 201 is sleeved outside the connecting rod, and the connecting plate is arranged between the connecting column 201 and the protective plate 100;

[0062] A connecting structure 300, the connecting structure 300 is arranged between the winding-up structure 200 and the column 400. The connecting structure 300 includes a connecting column 201, a spring piece 302, a threaded column 304 and a plug rod 306. The connecting column 201 is fixed at the upper end of the threaded column 304. The spring piece 302 is embedded inside the connecting column 201, and the plug rod 306 is fixed at the bottom of the motor box 202;

[0063] Reinforcement structure 500 is provided at the bottom end of the protection plate 100. The reinforcement structure 500 includes a mounting post 501, a spring B 502, a telescopic rod 503, an adjusting rod 504, and a sleeve 506. The mounting post 501 is fixed to the bottom end of the telescopic rod 503. The spring B 502 is wound around the outer side of the telescopic rod 503. The adjusting rod 504 is provided at the other end of the telescopic rod 503. The sleeve 506 is sleeved on the outer side of the spring B 502;

[0064] Safety prompt system 600 is used to monitor the use of protective tools and give safety prompts when problems occur. The safety prompt system 600 is integrated on the remote controller, so that the operator can receive monitoring data and alarms in real time. A display screen or a sound prompt can be set on the remote controller for displaying monitoring results and giving alarms. The safety prompt system 600 includes a sensor acquisition module 601, an Internet of Things sensor network 602, a data analysis module 603, a safety assessment module 604, and a safety prompt module 605;

[0065] The sensor acquisition module 601 uses sensors to monitor the protective tools and the construction environment;

[0066] The Internet of Things sensor network 602 is used to transmit the monitoring data from the sensor acquisition module 601. The data is collected through sensor nodes, transmitted to the gateway through the communication interface, and then the gateway sends the data to the remote data analysis module 603 for processing and analysis;

[0067] The data analysis module 603 is used to receive the monitoring data and perform fault analysis on the monitored data;

[0068] The safety assessment module 604 is used to evaluate the safety level of the results analyzed by the data analysis module 603;

[0069] The safety prompt module 605 is based on the results evaluated by the safety assessment module 604.

[0070] The embodiments of the present invention are also implemented through the following technical solutions.

[0071] In the embodiments of the present invention, the data analysis module 603 uses self-organizing mapping technology to analyze data, specifically including the following steps:

[0072] Step 1: Define the fault data, including the characteristics, thresholds, and conditions of the faults. Create a two-dimensional grid, assign a random weight vector to each node, select a sample from the data, use the Euclidean distance to measure the weight vector with high similarity to the sample, obtain the winning node, and map the similar data to adjacent positions on the grid. Therefore, the distribution of the data can be visually observed. By observing the activation patterns of the nodes on the grid, the changes in the data distribution can be monitored, thus revealing potential fault patterns;

[0073] Step 2: Determine the neighborhood of the winning node. The neighborhood function is used to determine which nodes around the winning node will update their weights, including Gaussian functions, rectangular functions, etc. All nodes within this neighborhood are updated with weights, adjusting the weights of the winning node and the nodes within its neighborhood to improve the similarity with the current input sample. Repeat the above process until the preset conditions are met;

[0074] Step 3: Map all the data into the two-dimensional grid, record the winning nodes of each data, calculate the number of winning times of the nodes. An abnormally high winning frequency may indicate the existence of duplicate or similar samples in the dataset, and the standard deviation of each node to evaluate the variability of the data within the node. Observe the clustering patterns on the two-dimensional grid. Abnormal clustering indicates data faults;

[0075] Step 4: Calculate the distance between each sample and the weight vector of the winning node. An abnormally large distance indicates that the sample is an outlier. An abnormally large distance means that the Euclidean distance between the sample and the weight vector of the winning node exceeds the threshold. Analyze the influence of each feature on the node weight to determine which feature causes the fault, and use the visualization of the two-dimensional grid to identify the patterns and unexpected behaviors in the data;

[0076] During the training process, if a certain node wins frequently, it indicates that there is a specific pattern in the input data. If it is found in subsequent monitoring that a new data point is not similar to any of the trained nodes, it indicates the emergence of a new fault pattern.

[0077] In the embodiment of the present invention, the security assessment module 604 uses the Monte Carlo simulation technique to perform security assessment on the data. The specific steps are as follows:

[0078] Step a: Determine the fault safety level of the analysis result of the assessment data analysis module 603, establish a mathematical model, and select a suitable probability distribution for the uncertainty parameters in the mathematical model, including normal distribution, uniform distribution, exponential distribution, etc.;

[0079] Safety level standard:

[0080] Level 1: Negligible fault impact, no action required;

[0081] Level 2: Minor faults, which require monitoring and recording;

[0082] Level 3: Medium faults, which require investigation and corrective actions;

[0083] Level 4: Severe faults, which require immediate actions to prevent accidents;

[0084] Step b, use a random number generator to generate random samples that conform to the parameter distribution, and input the generated random samples into the data model to obtain the calculation results;

[0085] Step c, perform a probability distribution on the calculation results, represent it using a probability density function or a cumulative distribution function, calculate risk metrics such as expected value, confidence interval, coefficient of variation, failure probability, etc., and compare the obtained risk metrics with the predefined safety level standards to evaluate the safety level of the failure data;

[0086] Step d, perform a sensitivity analysis on the parameters to determine which parameters have the greatest impact on the model output, and optimize the model. This helps to determine which parameters are the most critical in the model and require more attention and accurate estimation. Use methods such as the Morris method and the Sobol method to perform the sensitivity analysis.

[0087] In the embodiment of the present invention, a motor is provided inside the motor box 202. The output end of the motor is in transmission connection with the rotating rod 207. The rotating rod 207 is screwed to the connecting column 201. The other end of the rotating rod 207 is rotatably connected to a fixed block 203. By controlling the rotation of the rotating rod 207 by the motor, the connecting column 201 outside the rotating rod 207 is synchronously driven to rotate. The other end of the rotating rod 207 is inserted into the fixed block 203 and rotates inside the fixed block 203. The connecting plate includes two mounting plates 204 and several connecting plates 205. The end of the connecting plate 205 is provided with a connecting end 206. Adjacent connecting plates 205 are rotatably connected through the connecting end 206. The mounting plates 204 are arranged on the uppermost and lowermost connecting plates 205. The connecting plates 205 are designed in an arc shape. The connecting end 206 of the adjacent connecting plates 205 penetrates the fixing rod to fix the adjacent connecting plates 205. The two ends of the fixing rod are in threaded cooperation with the connecting end 206, and the connecting end 206 at other positions is rotatably connected to the fixing rod, so that when the connecting column 201 rotates, the protective plate 100 connected to the connecting column 201 through the connecting plate can rotate together therewith.

[0088] Specifically, by configuring a remote terminal, such as a remote control, the forward and reverse rotation of the motor in the motor box 202 is controlled, and the motor rotation controls the rotating rod 207 and the connecting column 201 to rotate synchronously. The connecting column 201 drives the protective plate 100 connected to it to rotate through the connecting plate. The protective plate 100 is lowered or rolled up according to the forward and reverse rotation of the motor. The operation is convenient. The number of protective plates 100 is set according to the height of the column 400, and the width of the protective plate 100 is matched with the distance between the two columns 400. The protective plate 100 is designed to be an arc or other shape that is compatible with the connecting column 201, which is convenient for rolling up.

[0089] In the embodiment of the present invention, the bottom of the fixing block 203 and the motor box 202 are fixed with a plug rod 306, which is used in conjunction with the connecting structure 300 through the plug rod 306. The upper end of the column 400 is provided with a mounting hole 307 that is threadedly matched with the threaded column 304. The threaded column 304 is installed on the column 400 through the mounting hole 307. The spring piece 302 is a cross design, and the center of the spring piece 302 is provided with a socket that is adapted to the plug rod 306. The plug rod 306 is conveniently inserted through the socket. The spring sheet 302 is passed through, and the spring sheet 302 is made of elastic metal material, so that the spring sheet 302 can be stretched open by the insertion rod 306. A spring A303 is arranged under the spring sheet 302, and both ends of the spring A303 are fixedly connected to the connecting column 201. An insertion cavity 305 is arranged inside the threaded column 304, and the insertion rod 306 is inserted into the inside of the spring A303. The insertion rod 306 is clamped by the spring A303, and the insertion rod 306 is inserted into the insertion cavity 305 of the threaded column 304.

[0090] Specifically, when performing temporary protection, first install the column 400, install the connecting structure 300 through the mounting hole 307 at the upper end of the column 400, select the protective plate 100 of the corresponding size according to the size of the column 400, insert the fixed block 203 and the plug 306 at the bottom of the motor box 202 into the connecting column 201 and the threaded column 304. When the plug 306 is inserted, the spring piece 302 and the spring A303 in the connecting column 201 are stretched open, and the plug 306 is clamped based on the elastic force, so that the winding structure 200 and the protective plate 100 are installed on the column 400. When disassembly is required, the winding structure 200 can be directly unplugged. The operation is convenient and simple, and the cost of the spring and the spring piece 302 is low and easy to replace.

[0091] In an embodiment of the present invention, the mounting post 501 is screwed to the protection plate 100. The mounting post 501 passes through the bottom end of the protection plate 100 and is fixed by screws. Damping washers are provided at both ends of the spring B502. The damping washers are arranged outside the telescopic rod 503 and are in threaded cooperation with the telescopic rod 503. By adjusting the position of the damping washers outside the telescopic rod 503, the use length of the spring B502 can be adjusted, so as to adjust the tension of the strengthening structure 500. One end of the adjusting rod 504 is in threaded cooperation with the telescopic rod 503, and the other end of the adjusting rod 504 is in threaded cooperation with a connecting block 505. By adjusting the telescopic length of the adjusting rod 504, the position of the connecting block 505 can be adjusted, which is convenient for the connecting block 505 to be connected to the building surface through connecting components such as bolts.

[0092] Specifically, when the protection plate 100 is unfolded for protection, the bottom surface of the protection plate 100 contacts the building surface and accumulates a part. Connecting components are embedded in the building surface. According to the distance between the protection plate 100 and the connecting components, the telescopic length of the adjusting rod 504 is adjusted. The mounting post 501 is installed on the bottom surface of the protection plate 100. The accumulated part of the protection plate 100 is lifted, and the connecting block 505 is connected to the embedded connecting components, and the accumulated part is used for stretching, so as to avoid the bottom of the protection plate 100 from being suspended when the strengthening structure 500 is installed. The lengths of the protection plate 100 and the strengthening structure 500 and the positions of the connecting components on the building surface need to be adjusted according to the actual construction and are not fixed;

[0093] When the wind blows the protection plate 100, the spring B502 can help pull the protection plate 100 to prevent the protection plate 100 from falling off due to wind pressure. Specifically, the spring can be compressed or stretched under the action of the wind force, so as to absorb and buffer the impact of the wind force and keep the protection plate 100 in close fit with the building surface.

[0094] Embodiment 2

[0095] Refer to the attached Figure 9 As shown, another construction method of a detachable and reusable steel structure roof protection tool provided by an embodiment of the present invention includes the following steps:

[0096] S1. Fix the upright posts 400 on both sides of the area to be protected. Fix the threaded posts 304 on the upright posts 400 through the mounting holes 307 at the upper ends of the upright posts 400. Select a protection plate 100 with a suitable size. Insert the insertion rods 306 at the bottoms of the fixing blocks 203 and the motor boxes 202 into the connecting columns 201 and the threaded posts 304, and ensure that the elastic pieces 302 and the springs A303 clamp the insertion rods 306;

[0097] S2. Use a remote control to control the motor to synchronously rotate the rotating rod 207 and the connecting column 201 to unfold the protection plate 100;
