Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for building construction, specifically to an auxiliary device for rapid positioning and fixing of building formwork. Background Technology

[0002] Formwork is a critical temporary support structure in concrete construction. Its positioning accuracy and fixing reliability directly affect the geometric dimensions, surface quality, and structural safety of concrete components.

[0003] Traditional methods of fixing construction formwork mainly rely on manual experience, using manual tools such as wooden wedges, steel pipe fasteners, and bolts for positioning and tightening. This approach has the following problems: Positioning accuracy is difficult to guarantee, and manual visual alignment is prone to positional deviations, resulting in dimensional deviations of concrete components; uneven locking force makes it difficult to accurately control the clamping force during manual operation, which can easily cause local deformation of the formwork or leakage of grout. The construction efficiency is low, and the positioning and fixing of a single formwork requires the cooperation of multiple people and repeated adjustments, which takes a long time; the lack of real-time monitoring and feedback means that it is impossible to detect in time when the formwork shifts or loosens during the concrete pouring process, which poses a risk to quality and safety.

[0004] With the development of industrialized construction and intelligent construction technology, formwork construction is gradually shifting towards mechanization and automation. However, existing formwork fixing devices mainly focus on improving mechanical structures and lack the ability to perceive and intelligently control key parameters such as formwork position, clamping force and tilt angle in real time. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide a building formwork quick positioning and fixing auxiliary device that can detect the formwork position deviation, clamping force and tilt angle in real time and automatically adjust the locking force.

[0006] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: a building template quick positioning and fixing auxiliary device, including a device body and a positioning calibration unit, a pressure detection unit, a locking drive unit and an edge processing unit integrated on the device body; The device body includes a fixed end, a clamping end, and a supporting end. The fixed end is connected and fixed to an external support structure. The clamping end clamps the building template, and the supporting end is used to abut against the back of the template to provide support. The positioning calibration unit is installed at the clamping end to detect the positional deviation between the building template and the baseline, and the pressure detection unit is used to detect the clamping force and support reaction force of the building template. The edge processing unit performs local analysis and processing of position deviation and clamping force, and outputs control commands to the locking drive unit. The locking drive unit is installed at the clamping end and adjusts the locking force based on the control commands.

[0007] Preferably, the device body further includes a tilt angle detection unit, which is installed on the support end to detect the installation tilt angle of the building template, and the edge processing unit acquires the installation tilt angle data for local analysis and processing.

[0008] Preferably, the edge processing unit includes a data preprocessing unit, a feature extraction unit, and a local decision-making unit; The data preprocessing unit filters and removes noise and outliers from the collected data; the feature extraction unit extracts clamping force distribution features and position deviation trend features; and the local decision-making unit outputs locking adjustment commands based on preset rules.

[0009] Preferably, it also includes an alarm notification unit, which is installed on a fixed end; The preset rules also include alarm thresholds. When any of the clamping force, position deviation, or tilt angle data exceeds the threshold, the local decision unit triggers an alarm command to the alarm prompt unit.

[0010] Preferably, the positioning calibration unit includes any one of a laser rangefinder sensor and an infrared beam sensor.

[0011] Preferably, the pressure detection unit includes a plurality of pressure sensors arranged at intervals along the contact surfaces of the clamping end and the support end; The edge processing unit calculates the locking force uniformity index based on the feedback difference of each pressure sensor.

[0012] Preferably, it also includes a wireless communication unit, which is communicatively connected to the edge processing unit to upload the processed data to the management platform. The wireless communication unit includes at least one of 4G, 5G, LoRa, or NB-IoT communication methods.

[0013] Preferably, the device body is further provided with a power management unit, which includes a rechargeable battery, a power monitoring unit and a low-power wake-up unit; The power monitoring unit monitors the battery power in real time and triggers a low-power mode when the power level is below a threshold. When the low-power wake-up unit receives a low-power mode command, it shuts down the positioning calibration unit, the pressure detection unit, and the wireless communication unit.

[0014] The advantages of this invention compared with the prior art are as follows: This invention achieves digital precise positioning by real-time detection of template position deviation through positioning calibration unit, and realizes automatic balanced adjustment of locking force by multi-point pressure detection and uniformity index calculation. The template space attitude is fully perceived by tilt angle detection, and the edge processing unit makes local decisions to achieve automated closed-loop control of positioning and fixing. In this invention, alarm and wireless communication enable remote monitoring and early warning. Based on power management and low power consumption design, the battery life is extended. It overcomes the problems of insufficient precision, uneven force, low efficiency and lack of real-time feedback in manual operation, and significantly improves the quality, efficiency and safety of template construction.

[0016] Figure 2 This is a schematic diagram of the control logic structure of the edge processing unit. Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Combined with appendix Figure 1-2 As shown, a rapid positioning and fixing auxiliary device for building templates includes a device body and a positioning calibration unit, a pressure detection unit, a locking drive unit, and an edge processing unit integrated on the device body.

[0019] The device body includes a fixed end, a clamping end, and a supporting end. The fixed end is connected and fixed to an external support structure. The clamping end clamps the building template, and the supporting end is used to abut against the back of the template to provide support. The positioning calibration unit is installed at the clamping end to detect the positional deviation between the building template and the baseline. The pressure detection unit is used to detect the clamping force and support reaction force of the building template. The edge processing unit performs local analysis and processing on the positional deviation and clamping force, and outputs control commands to the locking drive unit. The locking drive unit is installed at the clamping end and adjusts the locking force based on the control commands.

[0020] In one embodiment, the device body further includes a tilt angle detection unit, which is installed on the support end to detect the installation tilt angle of the building formwork. The edge processing unit acquires the installation tilt angle data for local analysis and processing. The tilt angle detection unit uses a dual-axis or tri-axis tilt sensor, installed on the back of the load-bearing surface of the support end, to measure the tilt angle of the support end relative to the horizontal and vertical planes, with a measurement range of ±90° and an accuracy of ±0.1°. The tilt angle detection unit and the edge processing unit are connected by a wire to transmit the tilt angle data in real time. The edge processing unit fuses and analyzes the tilt angle data with the position deviation data. When the formwork has both positional offset and tilt angle deviation, it is determined to be an overall displacement of the formwork, and the clamping position of the locking drive unit is adjusted first. When only tilt angle deviation exists and the position is accurate, it is determined to be a local settlement or deformation of the support end, triggering an alarm prompting the support foundation to be checked. In use, the edge processing unit includes a data preprocessing unit, a feature extraction unit, and a local decision-making unit. The data preprocessing unit filters and removes noise and outliers from the collected data. The feature extraction unit extracts the clamping force distribution features and position deviation trend features. The local decision-making unit outputs locking adjustment commands based on preset rules. The preset rules include positioning adjustment rules and locking force adjustment rules; The positioning adjustment rule is as follows: when the absolute value of the position deviation is greater than the allowable positioning deviation, the position adjustment command is output to the locking drive unit, and the clamping end is driven to move slightly in the opposite direction of the deviation until the position deviation falls into the allowable range. The allowable positioning deviation is set according to the dimensional accuracy requirements of the concrete component. The locking force adjustment rule is as follows: when the average clamping force is lower than the minimum locking force threshold, an increase command is output to increase the locking force; when the average clamping force is higher than the maximum locking force threshold, a decrease command is output to decrease the locking force; when the locking force uniformity index is lower than the uniformity threshold, a uniform force command is output to adjust the relative force of each clamping point. In one embodiment, an alarm notification unit is also included. The alarm notification unit is installed at the fixed end. The preset rules also include alarm thresholds. When any of the clamping force, position deviation, or tilt angle data exceeds the threshold, the local decision unit triggers an alarm command to the alarm notification unit. The alarm notification unit includes an audible and visual alarm and an LED status indicator. It is installed in a conspicuous position at the fixed end for easy observation by on-site construction personnel. The alarm thresholds include clamping force exceeding the limit threshold, position deviation exceeding the limit threshold, and tilt angle exceeding the limit threshold. When in use, the positioning calibration unit includes either a laser rangefinder or an infrared beam sensor. The laser rangefinder uses a phase-type or pulse-type laser rangefinder principle. It is installed on the reference side of the clamping end, emits a laser beam towards the surface of the building template and receives the reflected signal, calculates the distance between the sensor and the template surface, and obtains the position deviation by comparing it with the reference distance. The infrared beam sensor uses a pair of infrared emitting tubes and receiving tubes. The emitting tube is installed at the clamping end, and the receiving tube is installed at the corresponding position of the template baseline, or vice versa. When the template is in the correct position, the infrared beam is blocked or aligned with the receiving tube. When the template is offset, the light path is interrupted or the receiving intensity changes, thereby detecting the position deviation. The pressure detection unit includes multiple pressure sensors spaced apart along the contact surfaces of the clamping end and the support end. The edge processing unit calculates the locking force uniformity index based on the feedback difference of each pressure sensor, wherein the pressure sensors are thin-film pressure sensors or strain gauge pressure sensors; In one embodiment, a wireless communication unit is also included. The wireless communication unit is communicatively connected to the edge processing unit and uploads the processed data to the management platform. The wireless communication unit includes at least one of 4G, 5G, LoRa or NB-IoT communication methods. The built-in communication module is selected according to the network coverage conditions at the construction site. After receiving the data, the management platform stores, analyzes and visualizes the data, and supports remote viewing of the operating status, historical curves and statistical reports of each device. To adapt to different construction needs and reduce the need for external cables, a power management unit is also installed on the device body. This power management unit includes a rechargeable battery, a power monitoring unit, and a low-power wake-up unit. The power monitoring unit monitors the battery level in real time and triggers a low-power mode when the level falls below a threshold. The low-power wake-up unit, upon receiving a low-power mode command, shuts down the positioning calibration unit, pressure detection unit, and wireless communication unit. In specific implementation of the present invention, The fixed end of the device body is connected and fixed to the external support structure by bolts, clips or welding to ensure the overall stability of the device. The building template is placed between the clamping end and the support end. The positioning calibration unit is activated to detect the positional deviation of the template from the baseline. Based on the pressure detection unit, the clamping force of the clamping end and the support reaction force of the support end are detected. The tilt angle detection unit detects the installation tilt angle of the template. The edge processing unit makes a judgment by combining the positional deviation, clamping force and tilt angle data. If any one of them exceeds the alarm threshold, the alarm prompt unit is triggered to issue an audible and visual alarm and the alarm information is uploaded to the management platform through the wireless communication unit. During the concrete pouring process, the device continuously monitors the formwork status, and the edge processing unit periodically analyzes data trends to promptly detect abnormalities such as formwork displacement, loosening, or deformation, automatically adjusting the locking force or triggering an alarm to ensure construction quality and safety.
