For a better understanding of the invention, and to show how the same may be carried into effect, reference will now be made, by way of example, to the accompanying drawings, in which:
The need for a form pressure concrete monitor arises from the critical importance of ensuring the safety, precision, and efficiency of concrete pouring processes in construction projects. Traditional methods of monitoring form pressure have proven inadequate, leading to various challenges and potential risks. Without an advanced, reusable form pressure concrete monitor, construction professionals lack reliable means of accurately gauging and controlling the immense forces exerted by concrete during placement.
A significant concern is the potential danger posed to workers caused by flying bolts and other hazards resulting from formwork blowouts during the pouring process. Without reliable means of monitoring and controlling form pressure, the safety of on-site personnel may be compromised, and construction sites become susceptible to accidents and injuries. Furthermore, the significant financial implications of costly and time-consuming formwork blowouts highlight the critical role of a form pressure concrete monitor. These blowouts cause significant project delays, as well as budget overruns and wasted resources.
The numerous challenges and safety concerns persist today. Conventional methods and tools for monitoring concrete form pressure have exhibited notable shortcomings, prompting the need for innovative, calibrated, and reusable alternatives.
Conventional form pressure monitoring systems often lack calibration, reducing their precision and accuracy. Conventional systems are typically single-use and costly, as they must be immersed within the formwork and concrete to take accurate measurements, rendering them impractical and costly for repeated use across various construction projects. In contrast, the various form pressure concrete monitoring systems disclosed herein break away from this restrictive pattern, ensuring high precision in measuring compressive forces without needing to be embedded within the formwork, allowing for accurate and controlled management of concrete placement during construction projects.
Existing tools and equipment for monitoring form pressure often fail to meet the specific demands of concrete pouring. Some solutions use single-use monitors that are not specifically designed for the complexities of form pressure, and these are typically tied to the form or formwork itself to measure the pressure exerted by the concrete during the pour. The concrete form pressure monitor described here, however, is attached to the form tie and employs a custom-designed load cell assembly, engineered to precisely measure forces, weight, and pressure from the expansion of form ties. This departure from conventional practices marks a significant advancement in form pressure monitoring.
Disclosed herein is a novel form pressure concrete monitor addressing the complex challenges and safety concerns inherent in concrete pouring during construction projects. The present disclosure details the form pressure concrete monitor, its structural intricacies, operational processes, software components, and potential applications.

Each load cell 130 may be secured to a form tie 120 using appropriate fastening means. In embodiments, the load cell 130 is secured by sliding it onto the form tie 120, followed by placing a load-bearing compression-resistant metal washer 132 over the load cell 130, and fastening it with a nut 133. Alternative fastening methods such as locking nuts, rivet nuts, flange nuts, wedge locking nuts, hydraulic tensioners, and more may be employed to secure the load cell 130 to the form tie 120.
Integrated into or connected to the load cell 130 is a multi-functional communication and processing unit 136 that facilitates additional functionalities, as described later with respect to

The multi-faceted bearing plate 140 includes a load-bearing surface 140a and a displacement surface 140b. The load-bearing surface 140a is configured to receive and distribute the compressive forces exerted by the form tie 120, ensuring that the pressure from the concrete during the pouring process is accurately transmitted to the internal sensors, as discussed below. The displacement surface 140b, serves to manage the displacement of the load cell 130 under stress, allowing for a controlled response to the applied pressure, which will be translated into measurable signals by the multi-functional communication and processing unit 136. In embodiments, the displacement surface 140b is less than 1 inch in thickness.
The seal plate 150, positioned opposite the multi-faceted bearing plate 140, acts as a closure to protect the internal components from external environmental factors, such as moisture, debris, concrete, and more. In this configuration, the seal plate 150 ensures that the internal sensors and electronic components remain intact and functional during and after the concrete pouring process. Depending on the embodiments, either the seal plate 150 or bearing plate 140 may be oriented to face the formwork 110 and come into contact with the form tie 120.
In embodiments, the entirety of the load cell 130, including the multi-faceted bearing plate 140 and the seal plate 150, is made of aluminum. In further embodiments, the load cell 130 is fabricated from 6061 aluminum, a material suitable due to its strength, corrosion resistance, and suitability for machining. In further embodiments, the material used is 6061-T6 aluminum, which has been treated to enhance its mechanical properties, providing increased yield strength and tensile strength. These properties make the material ideal for load-bearing applications, such as the form pressure monitoring system, assembly, and apparatus 105, where both lightweight characteristics and high strength are necessary.
In embodiments, each plate—both the multi-faceted bearing plate 140 and the seal plate 150—is composed of a single, continuous piece of material with no breaks or seams, ensuring structural integrity and uniform distribution of force across the load cell 130. In other embodiments, the multi-faceted bearing plate 140 is formed by the load-bearing surface 140a and the raised annular ring 141 as separate components that are welded together, creating a unified structure capable of withstanding significant mechanical loads during operation.
The 6061-T6 aluminum used in some embodiments exhibits several mechanical properties that illustrate its suitability for this application. Illustrative properties include a yield strength of approximately 2.75e+08 N/m2 and a tensile strength of around 3.1e+08 N/m2. These properties ensure that the load cell can withstand the compressive forces typically encountered in concrete monitoring without experiencing undue deformation or failure. In terms of volumetric properties, an example configuration of the load cell made from 6061-T6 aluminum might exhibit a mass of approximately 0.721045 kg, which highlights the material's lightweight nature while maintaining the necessary strength for use in high-stress environments, with a volume of around 0.000267054 m3, and a density of 2,700 kg/m3.
It will be understood that the characteristics and properties of the aluminum described herein are illustrative, and the invention is not limited to this specific material or its properties. Other materials with similar or enhanced properties may also be used. For instance, other aluminums, titanium alloys, high-strength steels, and more may be employed. This is based on the desired use to achieve greater durability or flexibility in handling displacement, without sacrificing resistance to deformation under heavy loads. These materials offer a balance between strength, flexibility, and machinability, ensuring that the load cell design remains adaptable to a variety of construction environments and application requirements.

In embodiments, within the load cell's 130 enclosure, the internal cavity 134, houses various electronic components used for its operation, including one or more compression sensors 160 and one or more tension sensors 161. In further embodiments, the load cell 130 includes two compression 160 sensors and two tensions 161 sensors that are arranged in Wheatstone bridge configuration. In embodiments, additional sensors are users (e.g. four, six, eight, or more total sensors). In embodiments, other configurations may be utilized including, but not limited to, full-bridge configuration, half-bridge configuration, quarter-bridge configuration, and more.
In embodiments, the load cell 130 is configured in a full-bridge configuration wherein four sensors are placed symmetrically around the load cell 130 (e.g., at 0°, 90°, 180°, and 270° positions), with two in tension 161 and two in compression 160 as the load deforms or displaces the load cell 130. This allows for temperature compensation and ensures that the load cell is sensitive to vertical or axial forces, even if the load is slightly off-center. For example, if the load is applied vertically, strain gauges 160 placed on the sides of the load cell 130 would measure compression, while those on the strain gauges 161 would measure tension. The reverse may be true depending on the direction of the load.
In embodiments, the tension gauges 161 and the compression gauges 160 of the load cell 130 are configured in separate circuits to detect force applied to the load cell 130. The tension gauges 161 are positioned to measure the tensile strain on portions of the load cell experiencing stretching forces, while the compression gauges 160 are positioned to measure compressive strain on portions of the load cell 130 experiencing compressive forces. Each set of gauges 160, 161, in embodiments, is electrically isolated and connected to independent Wheatstone bridge circuits, allowing for separate and precise detection of tensile and compressive forces.
For those embodiments, the outputs from the tension and compression bridge circuits are combined using a signal processing unit 162 or microcontroller. The system can sum, filter, or otherwise process the signals from each bridge circuit to determine the net force acting on the load cell 130. This modular approach allows for flexibility and precision, as each type of strain is measured independently, providing high accuracy in detecting forces applied in both tensile and compressive directions. The system can also compensate for temperature fluctuations and non-uniform force distribution, which may otherwise affect the accuracy of a single circuit configuration, in some cases.
In yet other embodiments, the tension and compression gauges 160, 161, may be arranged in a hybrid full-bridge configuration, with the tension gauges 161 placed in one leg of the Wheatstone bridge and the compression gauges 160 placed in the opposite leg. This configuration allows the differential between tensile and compressive forces to be measured directly, outputting a single signal representing the total applied force. The system compensates for off-axis loading and thermal variations, enhancing the overall sensitivity and reliability of the force measurements.
The internal cavity 134, in embodiments, houses a signal processing unit 162, analog to digital converter 163, a control unit 164, a wireless communication unit 165, a power supply 166 and other related components, collectively referred to as multi-functional communication and processing unit 136. In embodiments, the communication and processing unit or dongle 136 may be externally connected to the load cell 130 through an external interface, where a dedicated port is integrated into the load cell 130. In embodiment, the port is located on the side of the bearing plate 140. This configuration facilitates the transmission of force measurements to the external communication and processing unit 136. The connection between the load cell 130 and the unit 136 can be established using either a wired or wireless communication method, depending on the specific implementation.
The compression sensors 160 and the tension sensors 161 are strategically positioned within the cavity to directly measure the forces exerted on the bearing plate 140. When the load-bearing surface 140a receives compressive force, the resulting displacement is detected by the sensors 160, 161 and processed by the communication and processing unit 136 which converts the physical strain into an electrical signal.
In embodiments, the compression sensors 160 and tension sensors 161 are used to measure strain, which represents the deformation or displacement of the bearing plate 140 when subjected to forces such as the expansion of portions of the form tie 120 due to the expansion of the formwork panels 111 and 112. These sensors 160, 161 are capable of detecting forces such as tension, compression, bending, or twisting that occur during the expansion or movement of the formwork assembly 110. In further embodiments, the compression sensors 160 consist of thin metallic materials arranged on opposite ends and placed in close proximity to the hollow ring cavity 146, bonded to the interior surface of the depressed ring 143 of the bearing plate 140.
While the size of the sensors 160, 161, as shown may be relatively small, the sensors 160, 161, may be of any size up to covering the entire depressed area 143 of the bearing plate 140. In embodiments, a metal wire mesh is integrated into one or more sensors 160, 161, where it functions as a conductive element that deforms under applied stress or pressure. The deformation of the wire mesh results in measurable changes in electrical properties, such as resistance or capacitance, enabling the sensors to detect and quantify mechanical forces with high precision. The wire mesh may also be integrated into the depressed area 143 and covering the entirety of the depressed area's 143 surface.
The sensors 160, 161 measures the amount of deformation per unit length, often expressed as a ratio, such as microstrain. Strain can occur if the bearing plate 140 is subjected to tension, stretching, and/or compression. The sensors 160, 161 can also be used to measure stress by relating strain to stress through material properties, using principles such as Hooke's Law for materials operating within their elastic range.
When a force is applied to the load-bearing surface 140a, the bearing plate 140 undergoes slight displacement or deformation, causing the compression sensors 160 to stretch or compress along with the internal surface of the bearing plate 140. This deformation induces a measurable change in the electrical resistance of the sensors 160, where the magnitude of resistance change is directly proportional to the strain exerted on the load-bearing surface 140a. The strain detected by the sensors allows for accurate real-time monitoring of the forces acting on the load cell 130.
In embodiments, the compression sensors 160 and tensions sensors 161 are arranged to precisely capture deformation from both compression and tensile forces. In embodiments, the compression sensors 160 are positioned on opposite side on the depressed ring 143 near the hollow ring cavity 146, which experience the most significant strain during operation. The tension sensors 161 are positioned on opposite side on the depressed ring 143, rotated 90° from the compression sensors 160, further away from the hollow ring cavity 146, in embodiments, which experiences the least strain during operation. As the bearing plate 140 deforms or displaces under load, the strain is measured through the sensors 160, and communication and processing unit 136 captures this data as electrical signals, which can then be processed and converted into force measurements.
These sensors 160, 161 may be configured as part of a Wheatstone bridge circuit, maximizing sensitivity by placing sensors at key deformation points-measuring both compressive and tensile strains on different location on the bearing plate 140. This arrangement provides precise monitoring of compressive forces exerted on the load-bearing surface 140a, as well as any bending or twisting forces experienced by the bearing plate 140.
The compression sensors 160 and tension sensors 161 are strategically positioned within the internal cavity 134 to directly measure the forces exerted on the bearing plate 140. When the load-bearing surface 140a receives a compressive force, the resulting displacement of the load bearing surface 140a and displacement surface 140b is detected by both the compression sensors 160 and tension sensors 161, which transmit the information to the communication and processing unit 136. This unit 136 processes the physical strain and converts it into an electrical signal for further analysis.
After the compression sensors 160 and tension sensors 161 measure the strain on the bearing plate 140, the collected data is processed and transmitted through a series of components housed within the internal cavity 134, which are part of the communication and processing unit 136. Once the compression sensors 160 and tension sensors 161 detect strain, the raw electrical signals generated from the deformation are sent to the signal processing unit 162 to be filtered, amplified, and conditioned for further analysis. The signal processing unit 162 removes any noise or interference, ensuring the signals accurately reflect the strain exerted on the load-bearing surface 140a and displacement surface 140b. It may also normalize or stabilize the signal to account for temperature variations or other environmental factors.
After the signals are processed, the analog to digital converter 163 takes these conditioned analog signals and converts them into digital data. This conversion is necessary because digital data can be more easily processed, stored, and transmitted by the subsequent electronic systems. The ADC 163 quantizes the continuous analog signal into discrete values, ensuring the strain data is accurately represented in a format suitable for digital processing.
Once the strain data is digitized, it is sent to the control unit 164. The control unit 164, in embodiments, is responsible for managing and coordinating the overall operation of the communication and processing unit 136. In embodiments, it applies algorithms to calculate the actual force, pressure, or stress being exerted on the bearing plate 140, based on the digital strain data received from the ADC 163. The control unit may also perform error-checking and validation of the data to ensure it is within expected ranges, or flag any anomalies for further inspection.
After the control unit 164 processes the data, the results, such as the measured force or strain, are transmitted to an external device or monitoring system via the wireless communication unit 165. This unit allows for real-time data transmission, enabling remote monitoring of the system. The wireless communication unit uses protocols such as Wi-Fi, BLUETOOTH®, LTE, or another low-power wireless standard to send data from the load cell to a central hub or mobile device where it can be analyzed further.
The communication and processing unit 136 is powered by the power supply 166, which may consist of batteries, a rechargeable power source, or another energy-harvesting method. The power supply 166 ensures continuous operation of the signal processing unit 162, analog to digital converter 163, control unit 164, and wireless communication unit 165. Depending on the application, the power supply 166 may be optimized for low power consumption, especially if the system is meant to operate for extended periods in remote locations without easy access to recharging or replacement.
As described above, the load cell assembly 130 is configured to detect the forces exerted on the formwork assembly 110 through a variety of strain gauges 160, 161 using one of the many configurations disclosed here. The load cell 130 assembly, in embodiments, is attached to a form tie 120, enabling the system to accurately measure both compressive and tensile forces acting on the formwork, providing monitoring of forces transferred from the formwork during the concrete pour.
In embodiments, the system, assembly, and apparatus 105 further comprises an accelerometer, which works together with the sensors 160, 161, to provide real-time data on the structural integrity of the formwork during construction and concrete pouring. The accelerometer is configured to detect external vibrations that may affect the formwork assembly 110. These vibrations can be caused by various construction activities, including, but not limited to, the use of devices inserted into fresh plastic concrete, external vibrators mounted on the formwork assembly 110, equipment operating near the formwork assembly 110, vibration caused by the pouring of concrete into the formwork assembly 110, vibration caused by the expansion of the formwork assembly 110, vibration as a result of pressure applied to the formwork assembly 110, and more. The accelerometer provides vibration data that may influence the pressure exerted on the formwork assembly 110, ensuring the system 105 can dynamically adjust to changes during the concrete pouring process.
The communication and processing unit 136, in embodiments, is operatively connected to both the load cell assembly 130 and the accelerometer, and it is configured to receive outputs from the pressure sensors 160, 161 and vibration data from the accelerometer. Upon receiving this data, the communication and processing unit 136 analyzes the outputs to determine the forces exerted on the formwork 110 and identifies any vibration events that may impact those forces. For example, vibrations from the formwork assembly 110, such as through the expansion of the formwork 110, can introduce variations in the pressure on the formwork 110, which the processor will detect and compensate for by adjusting the detected forces exerted on the formwork based on the vibration data. This adjustment, in embodiments, ensures that the system can provide accurate readings of the forces affecting the formwork 110, even in the presence of external vibrations, such as external vibrators mounted to the exterior of the formwork 110. The communication and processing unit 136 compares the compensated forces to a safety threshold, which in embodiments depends on the pressure ratings of the mounting surface such as form ties 120, to ensure that the pressure on the formwork 110 remains within safe operational limits. The specified range or safe operational limits is, in embodiments, specified as any percentage of the pressure ratings, such as 10%, 20%, and so on. If the forces exceed the threshold or the specified operational limits, the system 105, in embodiments, generates signals to alert construction personnel.
The system 105, in embodiments, is also capable of generating signals to indicate the occurrence of vibration events and whether the adjusted forces fall within the specified range of the predefined threshold. These signals provide real-time feedback to construction teams, ensuring that they are aware of any potential issues with the formwork's structural integrity. Additionally, the communication and processing unit 136, in embodiments, is configured to transmit the analyzed outputs, identified vibration events, and signals to a user device, a server, a cloud, or other data structure for remote monitoring, further processing, storing, and more.
Further enhancing the system's functionality, the communication and processing unit 136, in embodiments, is equipped with a filtering mechanism to filter out low-magnitude vibrations that do not significantly, or negligibly, affect the formwork 110. This ensures that the system focuses on relevant vibration events without overreacting to minor disturbances. Additionally, the load cell assembly 130, in embodiments, includes a temperature sensor, which monitors environmental conditions such as temperature. The communication and processing unit 136 adjusts the measured forces based on any changes in temperature, ensuring that fluctuations in environmental conditions are accounted for in addition to fluctuations in vibration.
Similarly, a method for monitoring concrete formwork pressure is also disclosed. In embodiments, the method involves detecting forces exerted on the formwork 110 using the load cell assembly 130, detecting vibrations using the accelerometer, and receiving data from these components via the communication and processing unit 136. The communication and processing unit 136 then analyzes the data to determine exerted forces and identifies vibration events affecting pressure on the formwork 110. The method, in embodiments, further includes adjusting the determined forces, comparing the adjusted forces to a predefined threshold, and generating signals based on whether the forces are within a safe, specified range (e.g. 10% of pressure ratings of the mounting surface of the load cell 130). The signals and analyzed data are then transmitted to and/or displayed on a device, a cloud server, a storage unit, and more.

The bearing plate 140 forms the upper portion of the load cell 130 and, together with the seal plate 150, encloses the internal cavity 134. This cavity 134 may be used to house various components (not shown in this view), such as sensors and processing units. The internal cavity 134 extends around the hollow ring cavity 146, with dimensions of approximately 1.1 inches, in embodiments. The cavity 134 is formed by the depressed area 143 of the bearing plate 140 and the corresponding depressed area 152 of the seal plate 150.
The load cell 130 is secured together using flush-mount fasteners 135, which pass into the blind holes 144 in the bearing plate 140 and through the through countersunk holes 151 in the seal plate 150. Between the two plates 140, 150, to ensure a tight seal and protect from environmental elements, an annular groove 145 is provided on the outer portion of the hollow ring cavity 146. This groove is designed to house a reversed O-ring 147, which seals the connection between the bearing plate 140 and the seal plate 150, while still allowing the form tie 120 to pass through the center of the load cell 130. This configuration ensures that the load cell 130 remains tightly sealed and structurally sound during operation, while also accommodating the necessary components and providing an efficient passage for form ties.
Referring to
Blind holes 144 are evenly spaced around the plate 140, allowing for secure attachment of the seal plate 150 using flush-mount or countersunk fasteners 135. The annular groove 145 is positioned on the outer edge of the hollow ring cavity 146 and is designed to house the reversed O-ring 147, which seals the connection between the bearing plate 140 and the seal plate 150, ensuring the internal cavity remains protected from external elements. The O-ring 147 may be used of a hard, extrusion-resistant material such as nylon, Hytrel, high durometer nitrile, fluorinated ethylene propylene (FEP), perfluoroelastomer (FKM), nitrile butadiene rubber (NBR), polytetrafluoroethylene (PTFE), hydrogenated nitrile butadiene rubber (HNBR), and more.
The seal plate 150 includes several through countersunk holes 151, which extend entirely through the plate 150. These holes are designed to receive the flush-mount fasteners 135, securing the seal plate 150 to the bearing plate 140. The depressed ring 152 is positioned around the perimeter of the seal plate 150, with a diameter closely matching the corresponding depressed ring 143 on the bearing plate 140. At the center of the plate 150, the ring recess 153 is designed to receive at least part of the annular ring 142, which forms part of the hollow ring cavity 146. The ring recess 153 works in conjunction with the reversed O-ring 147, creating a tight seal with the annular ring 142, ensuring that the load cell 130 is properly sealed and components within it are protected. This arrangement prevents external contaminants from entering the internal cavity 134 and maintains the integrity of the load cell 130 during operation.
In embodiments, the diameter of the ring recess 153 on the seal plate 150 is marginally larger than the exterior diameter of the hollow ring cavity 146, allowing for a snug fit, while giving room for the ring 146 to move. In further embodiments, the depths of the depressed rings 152 and 143 differ, with the depressed ring 143 being deeper. This difference allows for proper spacing between the two plates, accommodating internal components and allowing for displacements. In yet further embodiments, the through countersunk holes 151 are marginally larger than the blind holes 144, allowing fasteners 135 to be inserted and countersunk properly.

At step 705, the system 105 is powered on, activating the power supply 166 for the load cell 130 and associated electronic components, including the communication and processing unit 136. During this step, calibration is performed to establish an initial baseline or zero-point, ensuring accurate force measurement. In embodiments, the baseline is calculated and determined during the calibration process. In further embodiments, the baseline incorporates user input, such as the type of concrete and other relevant data, to enhance calibration accuracy. This calibration sets the tare value before any load is applied to the formwork assembly 110, accounting for any initial load or imperfections in the setup. The system is also initialized to manage the transmission of force data collected from the sensors 160, 161 of the load cell 130, packaging this data into a raw data packet that may include fields for the device name, sensor readings, and relevant metadata. Additionally, the system verifies that the load cell 130 is correctly communicating with the wireless communication unit 165, ensuring smooth data transmission for further processing and monitoring.
The calibration process for the system 105 begins with the initial setup of the load cell 130 and its associated components, including the compression sensor 160 and tension sensor 161. Before any load is applied, the system 105 is zeroed out through a baseline calibration, which involves setting a tare value to eliminate any pre-existing forces or environmental factors that might affect the readings. In some embodiments, the system 105 allows for operator input regarding the type of concrete and other relevant data, ensuring the baseline is accurately calibrated to reflect real-world conditions.
Once the baseline is established, the system 105 proceeds to load increment calibration, where known weights are applied at regular intervals. These intervals may be set at 10,000-pound increments but may vary based on the specific requirements. During each interval, the system records the response of the sensors to ensure that the load cell's 130 output is linear and consistent across the entire range of applied forces.
In further embodiments, pressure calibration is incorporated into the process, taking into account the rated capacity of the form ties 120. This ensures that the system 105 not only measures weight but also accurately captures the pressure exerted. The calibration process continues with the application of a calibration constant, which is used to adjust raw data from the sensors 160, 161 to produce meaningful force and pressure readings in standardized units, such as pounds or Newtons.
In embodiments, to calculate the calibration factor for a load cell 130, the process begins by averaging sensor readings at specific applied weights, e.g., 4000, 8000, 16000 units. For each weight, multiple sensor readings are taken, and their average is calculated to reduce noise and improve accuracy. These averaged values are then plotted on an XY graph, where the X-axis represents the applied weights, and the Y-axis represents the sensor readings. The slope of the line of best fit is determined, for example, by determining the change in sensor readings over the change in applied weights. The calibration factor is obtained by taking the inverse of the slope. This calibration factor is then applied to convert future sensor outputs into accurate force measurements during the operation of the load cell system. This process ensures that the system provides reliable and precise data for real-time force monitoring.
At step 710, as the concrete pour begins, the system 105 detects the initial force applied to the formwork assembly 110 via the bearing plate 140. This initial pressure may serve as a reference point before any significant force accumulates. The system 105 is designed to gather raw data from the load cell 130, which is subsequently processed to calculate various user-readable data, including force and temperature. Prior to calculating any weight or force, the system first zeroes out any baseline readings from the load cell 130 by setting a tare value, ensuring accuracy. The raw data from the load cell 130 may be collected over multiple samples to minimize noise and fluctuations, resulting in a more stable and reliable reading. This raw data is then converted into a relevant measurement, such as force measurements, by applying a calibration constant that adjusts for the specific characteristics of the load cell 130 being used.
At step 715, the compression sensor 160 and tension sensor 161 integrated into the load cell 130 continuously monitor the strain and forces exerted on the system 105. These sensors 160, 161 are strategically mounted on key locations of the bearing plate 140. The detected forces represent the pressure applied to the formwork panels 111, 112 and form ties 120. As compressive force from the concrete is applied to the formwork assembly 110, strain gauges embedded within the sensors experience mechanical deformation. In addition to force data, the system 105 also measures environmental conditions, such as barometric pressure and temperature, using integrated sensors. These environmental values are periodically read and included in the transmitted data, providing a comprehensive overview of the system's 105 operational conditions.
At step 720, as the load-bearing surface 140a is subjected to compressive forces, both the compression sensor 160 and tension sensor 161 detect the resulting mechanical strain on the multi-faceted bearing plate 140. In embodiments, the detected strain is directly proportional to the magnitude of the applied compressive forces, providing an accurate measurement of the pressure exerted on the system 105. The mechanical deformation of the bearing plate 140 causes a change in electrical resistance within the strain gauges integrated into the sensors 160, 161. This change in resistance is proportional to the amount of strain, which in turn corresponds to the force being applied, allowing for precise force measurement through the strain gauge response.
At step 725, the strain data captured by the sensors 160 and 161 is converted into electrical signals. In embodiments, this data is routed through a Wheatstone bridge circuit integrated within the load cell 130. This configuration detects small changes in resistance caused by the applied strain, converting these changes into a differential voltage signal.
At step 730, if the generated electrical signal is small, a signal amplifier integrated into the signal processing unit 162 boosts the voltage to a readable level, ensuring that even small force changes can be accurately detected and processed. In embodiments, a precision amplifier is utilized, which boosts the signal to a level suitable for further processing. This amplified signal accurately represents the magnitude of the forces acting on the load-bearing surface 140a, ensuring reliable force measurement.
At step 735, the amplified signal is converted from an analog voltage into digital force data through the analog-to-digital converter 163. This conversion transforms the continuous analog signal into a digital format, enabling further processing and electronic storage. The digital output, while proportional to the applied force, may need to be calibrated and converted into meaningful force units, such as Newtons or pounds.
At step 740, the digital force data is processed by the control unit 164. This process, in embodiments, involves applying a calibration constant, established during the system's 105 initial calibration, to account for the specific characteristics of the load cell 130, such as its sensitivity in millivolts per volt per Newton. This ensures that the force data is both accurate and reflective of the actual conditions being measured.
At step 745, the processed force data is transmitted wirelessly via the wireless communication unit 165 to a remote user interface, enabling real-time monitoring of the formwork pressure. The system 105 supports multiple transmission protocols, including BLUETOOTH®, Wi-Fi, and in some embodiments, LTE, allowing for flexible communication with devices such as smartphones, wearable devices, computers, cloud-based servers, and more. This ensures that users can monitor data continuously during the concrete pour, facilitating quick decision-making. The system 105 is also capable of broadcasting data to external devices, which can access the transmitted information for real-time analysis.
The data, including force and other measurements and time-stamped pressure changes, may be packaged into wireless packets and sent to the user interface. In further embodiments, the data is also transmitted to cloud servers for archiving and further processing. The system 105 is designed to handle potential errors during sensor initialization or calibration by outputting diagnostic messages to the serial console, ensuring proper troubleshooting and system maintenance. This robust wireless communication ensures accurate, timely data transfer for optimal monitoring and control during concrete pours.
At step 750, the transmitted data is displayed in one or more formats, such as text or graphical representations, illustrating the real-time pressure distribution across the formwork panels 111 and 112. This allows operators to monitor the force exerted within the formwork assembly 110 in real-time, ensuring that the pressure remains within safe operational limits.
The user interface, which may be a mobile app, a web-based application, desktop software, or similar, receives the wireless data and provides real-time visualization of the pressure distribution from one or more load cells 130. Graphical representations show the force applied at various points of the formwork assembly 110, offering a clear view of where the pressure is concentrated. The system 105 continuously updates this display, allowing operators to observe fluctuations in force, and other parameters, during the concrete pour, facilitating informed decision-making to maintain structural integrity.
At step 755, if the force or pressure exceeds pre-set safety thresholds-such as regulatory limits or the rated capacity of critical components, for example, the form ties 120—the system 105 automatically triggers alerts to notify the operator. The system 105 is configured with threshold monitoring, where maximum allowable pressure limits are set for the formwork. These alerts can be visual, auditory, notifications on the user interface, on a display on the load cell 130, a combination of these, and more ensuring that any potential risks, such as formwork failure, are promptly identified and addressed. This real-time alert system is crucial for preventing structural damage and ensuring the safe continuation of the concrete pour.
At step 760, based on real-time data analysis, the system 105 may prompt the operator to adjust the pour rate if necessary, to ensure the applied pressure remains within safe limits, optimizing the integrity of the formwork during the concrete pour. Alternatively, if pressure is well within safe limits, prompt user to increase speed while staying in safe limits to increase efficiency.
At step 760, based on real-time data analysis, the system 105 may prompt the operator to adjust the concrete pour rate if necessary to ensure that the applied pressure remains within safe limits, thereby optimizing the structural integrity of the formwork during the pour. Alternatively, if the pressure remains well within the safe limits, the system 105 may prompt the operator to increase the pour rate while maintaining safety, thereby improving overall efficiency.
At step 770, all pressure and force data are stored for post-pour analysis, allowing for comprehensive review and optimization of future concrete pours. The system 105 archives pressure readings, timestamps, and event alerts in onboard memory or on a connected cloud service, ensuring that the data is accessible for quality control and structural assessments. The stored data may be utilized to analyze pressure distribution patterns, verify that the pour remained within safety parameters, and identify opportunities for improving the efficiency and safety of subsequent pours.
This process repeats continuously, allowing for real-time monitoring of both weight and environmental conditions. The system 105 is designed to be highly accurate, with provisions for calibration and tare adjustments, and is able to transmit data wirelessly for convenience and integration into broader systems. The system 105 ensures that data can be accessed from a variety of devices, enhancing its versatility in various applications.

This structured database design allows for real-time monitoring, detailed historical analysis, and optimized operation of the form pressure monitoring system.
The structural components system, including the load cell, work in conjunction with the system's functional modules to provide real-time data analysis and decision-making capabilities. The load cell, designed to measure compressive forces exerted by the concrete, transfers these physical pressures into electrical signals via the embedded compression and tension sensors. These signals are then transmitted to the processing unit, which interprets the data in the context of the ongoing concrete pour. The processing unit evaluates the pressure distribution in real time, comparing the data against pre-set safety thresholds, and sends actionable feedback to the user interface. This integration allows for immediate adjustments, such as altering the pour rate, thereby optimizing both the safety and efficiency of the concrete pouring process. By maintaining constant communication between the load cell's sensors and the processing unit, the system ensures that the structural integrity of the formwork is preserved while minimizing the risk of blowouts or structural failure.
The various embodiments of the system disclosed herein may incorporate advanced features designed to enhance functionality in challenging construction environments. One such feature is the LTE autosense multiband function, which maximizes signal strength in high signal-attenuating environments, such as those commonly encountered in concrete forming assemblies. This technology ensures consistent and reliable data transmission even in dense material surroundings, enabling continuous monitoring without signal degradation.
Machine learning (ML) models may be employed within the system to enable a smart reliquification warning notification system. This feature provides project managers with real-time alerts regarding potential concrete reliquification events, offering better control over heavy equipment operation and environmental factors that could otherwise destabilize the concrete. By incorporating ML algorithms, the system intelligently anticipates risks and issues warnings before a reliquification event occurs, optimizing the safety and efficiency of the construction process.
Additionally, the system may utilize artificial intelligence (AI) to assist in identifying the end of concrete pours, thereby eliminating the need for project managers to continuously monitor the site to determine when conditions are met for removing concrete forming. This AI-enabled end-of-pour detection ensures that removal occurs at the most optimal time, reducing human error and increasing operational efficiency.
For battery-operated components, the system may implement AI-assisted deep sleep and soft power-off rules, which maximize battery life by intelligently adjusting power usage based on real-time operational needs. This feature is critical for long-term monitoring, particularly on remote or hard-to-access construction sites where frequent battery replacement is impractical.
In certain embodiments, visual and auditory feedback may be provided to the users. For instance, the system could include bright, multi-color LED striping along the load cell body, providing real-time visual feedback on the force being applied to the material and alerting the user when the material is approaching maximum load limits. In addition, auditory alarms may be triggered when force-loading thresholds are breached, offering immediate warnings about critical load conditions.
The system may also be integrated with AI-assisted customized statistical process control (SPC) rules, which alert users to impending and actual violations of force-loading limits. By continually analyzing real-time data, the AI ensures that project managers are notified of potential risks before they become critical, thereby allowing for timely intervention and avoiding costly errors or structural failures.
Embodiments may further include proprietary BLUETOOTH® advertisement protocols to facilitate seamless multi-factor authentication (MFA) in the IoT edge environment.

This feature allows for a flexible and self-healing network, ensuring that the system remains operational even when individual sensors or connections are compromised, further enhancing reliability in construction environments.
The various embodiments enclosed herein may utilize one or more of the features and capabilities described above, either alone or in combination, to enhance the functionality, reliability, and efficiency of the form pressure concrete monitor system in diverse construction environments. While the focus of the present disclosure is on concrete form applications, the system described herein has broad applicability across various industries. It is well-suited for industrial weighing, material testing, and other applications requiring precise force and weight measurement.
Put variously, the present disclosure includes a load cell that may incorporate transducers and/or sensors designed to convert mechanical forces into electrical signals, enabling precise measurement of force, weight, and pressure exerted by external elements, such as form ties. The sensing elements include highly sensitive components, such as strain gauges and/or piezoelectric crystals, for measuring force, along with optional temperature, humidity, and moisture sensors for assessing concrete curing conditions. When pressure is applied, these sensing elements undergo controlled deformation, resulting in measurable changes in electrical parameters, such as resistance or voltage, which provide an accurate indication of the magnitude and distribution of the compressive forces being applied. In embodiments, the load cell is designed and calibrated to withstand pressure in excess of 40,000 pounds.
In embodiments, to improve the accuracy of force measurements, the load cell houses an array of four sensors. Two sensors are positioned near the central opening, spaced 180 degrees apart, configured to measure compression. The other two sensors are located farther from the central opening, also spaced 180 degrees apart but rotated 90 degrees relative to the inner sensors, and are designed to measure tension. This arrangement enables the load cell to detect and analyze differential pressure between the two sets of sensors. In further embodiments, the sensors may be configured in a Wheatstone bridge circuit. When force is applied, the sensors, such as strain gauges, detect displacement of the load-receiving element, which causes changes in resistance. These resistance changes are proportional to the applied force and form the basis for measuring the load.
The upper housing of the load cell maintains a flat surface that facilitates consistent force distribution by utilizing a raised section around the central opening, which serves as the load-receiving element. This raised portion effectively transmits and concentrates the force onto the inner sensors, enabling precise pressure measurement and differential analysis.
To install the load cell, a user positions the load cell over a form tie that has been securely affixed to the formwork. The load cell is placed over the form tie using the central opening, a metal washer and a nut are placed over the load cell. The load cell, while mounted on the form tie, is not part of the formwork itself.
Another aspect of the disclosure is a data processing and transmission unit, which may be connected to the load cell via appropriate wiring or be formed as part of the load cell itself. The unit may include a custom-designed printed-circuit board (PCB) acting as the central hub, managing the system's functions, including interfacing with the load cell, processing data, and handling wireless connectivity. A dedicated data processing unit, which includes a microcontroller, memory, and specialized algorithms, may be utilized to collect raw data from the sensors and convert it into precise load measurements and pressure readings. A data storage unit with non-volatile memory stores historical records for future reference may also be included. The system may also include wireless communication modules such as near-field communication (NFC), BLUETOOTH®, Wi-Fi®, or mobile broadband networks. Adding a global positioning system (GPS) module can further enhance functionality by providing precise location tracking during concrete placement.
Users may input project-specific data to customize the monitoring process. This can include formwork size and dimensions, concrete type, ambient conditions, and more, ensuring that the monitoring parameters are tailored to each project. The system's interface allows users to input project data, access real-time readings, and take proactive steps to ensure successful concrete placement. If equipped with a GPS module, the system may also gather environmental information based on location. The system, in embodiments, analyzes historical data from past projects to provide predictive insights on factors such as curing time or pour speed, enabling users make informed decisions and optimize the timeline and quality of the project. Users may export data and generate reports detailing concrete pour parameters, environmental conditions, and other relevant metrics for quality control and regulatory compliance.
To use the system, the load cell is secured to the form tie, users initialized the load cell and related components, and using an external device track pressure build-up in real-time data. After the pour is completed, the load cell may be removed and stored for future use, with the collected data available for post-pour analysis and documentation.
