Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a verticality detection device for building construction formwork. Background Technology

[0002] In the construction industry, especially in the construction of vertical formwork for shear walls and columns, accurate verticality testing is crucial for ensuring project quality. Traditional verticality testing methods typically rely on a plumb line. A plumb line is a common tool that uses gravity to suspend a plumb line vertically, thus indicating whether the vertical formwork is vertical. Specifically, the plumb line uses gravity to keep a steel wire rope vertical, and the deviation value is read visually by comparing it with the edge of the formwork. Although this method is widely used, it has some shortcomings, especially its poor applicability in complex construction environments.

[0003] When obstacles exist at the construction site, the application of plumb lines becomes extremely difficult. Construction workers often cannot flexibly adjust the measurement position, and the accuracy of the measurement results is greatly reduced. Specifically, during the construction of vertical formwork for shear walls and columns, obstacles such as scaffolding, supports, and pipelines are inevitable, making it impossible to hang the plumb bob close to the formwork surface. Even if it can be hung close to the formwork surface, it is difficult for construction workers to accurately visually measure the deviation value.

[0004] This makes current plumb line equipment unsuitable for complex building formwork construction environments. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the above-mentioned deficiencies in the existing technology by providing a verticality detection device for building formwork, which can conveniently detect the verticality of building formwork with obstacles.

[0006] According to an embodiment of this utility model, a verticality detection device for building formwork is provided, comprising: a device body; two measuring point components, the two measuring point components being respectively installed on the left and right sides of the device body, the measuring point components being able to extend and retract in the horizontal direction and abut against the surface of the building formwork, the extending end of the measuring point components being provided with a gasket, the gasket being used to fit against the surface of the building formwork; when the gasket is in contact with the surface of the building formwork, the spatial posture of the device body is consistent with the spatial posture of the surface of the building formwork; a posture detection unit, housed within the device body, the posture detection unit being used to detect the spatial posture information of the device body; and a processing unit, electrically connected to the posture detection unit, being used to calculate the verticality measurement result of the building formwork based on the spatial posture information.

[0007] Optionally, the spatial attitude information of the main body of the device refers to the angle of deviation of the main body of the device relative to the direction of gravity.

[0008] Optionally, the measuring point assembly includes a slide rail and a sliding member. The slide rail is rigidly installed on the outer side wall of the main body of the device and extends in a horizontal direction. The sliding member is connected to the slide rail and can slide along the extension direction of the slide rail. The end of the sliding member near the building template is the telescopic end.

[0009] Optionally, the measuring point assembly further includes a locking unit for locking the slider at any position on the slide rail.

[0010] Optionally, the locking unit is a helical telescopic rod or an elastic locking structure.

[0011] Optionally, the gasket is a rectangular gasket.

[0012] Optionally, the gasket is made of a soft rubber material.

[0013] Optionally, the attitude detection unit is an IMU (Inertial Measurement Unit), which includes a gyroscope and an accelerometer.

[0014] Optionally, the device further includes a display unit, which is mounted on the outer side wall of the device body and electrically connected to the processing unit for displaying the verticality measurement results.

[0015] Optionally, the device may also include an auxiliary fixing mechanism, which is installed on the main body of the device and is used to temporarily fix the main body of the device to the building template or its supporting structure. The verticality testing device for building formwork in this invention uses a shim as a measurement reference point. By setting two retractable measuring point components, the shim, serving as the measurement reference point, can bypass obstacles and directly contact the surface of the building formwork. When the shim is in contact with the surface of the building formwork, its spatial orientation is consistent with that of the formwork; that is, the shim and the surface of the formwork are on the same plane, thus ensuring that the spatial orientation of the device body is consistent with that of the formwork surface. At this point, by detecting the spatial orientation information of the device body, the spatial orientation information of the formwork surface can be obtained, and the verticality measurement result of the building formwork can be calculated based on this spatial orientation information.

[0016] In summary, this building formwork verticality testing equipment can conveniently test the verticality of building formwork with obstacles. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] First, in order to facilitate understanding of the verticality detection equipment for building formwork in this application, it is necessary to further explain the application scenarios of the verticality detection equipment for building formwork.

[0024] In building construction, the construction of vertical formwork for shear walls and columns is a crucial step in ensuring the overall stability and lateral force resistance of the structure. The verticality of the formwork directly affects the geometric accuracy of the structure after concrete pouring. If the deviation exceeds the standard, it will not only affect the accuracy of subsequent node connections and assembly, but may also weaken the load-bearing capacity and durability of the structure. Traditionally, various methods are used on construction sites to check the verticality of the formwork, such as plumb lines, spirit levels, theodolites, total stations, and laser plumb lines.

[0025] Taking the conventional plumb line method as an example, the plumb line uses gravity to keep the steel wire rope vertical, and the deviation value is read by visually comparing it with the edge of the template. This method is low-cost and uses simple tools, but it relies entirely on manual visual inspection and reading, and its accuracy is easily affected by the operator's eyesight and experience. Under the influence of wind, scaffolding vibration, or interference from obstacles on site, the plumb bob is difficult to suspend stably, resulting in fluctuating readings and difficulty in fixing the measuring point position, making it unsuitable for long-span or high-altitude operations.

[0026] It is evident that the accuracy of plumb line suspension depends on the operator's experience and skills, and usually requires manual visual inspection, which may lead to large measurement errors.

[0027] Furthermore, the traditional plumb line method is cumbersome and time-consuming. Construction workers need to precisely install the plumb line and perform multiple checks to ensure accurate verticality measurements. This not only increases the labor intensity of construction but also affects efficiency, especially in large-scale projects where frequent verticality measurements and adjustments lead to significant time waste.

[0028] In addition, the traditional plumb line method cannot achieve real-time data acquisition and automated calculation, so it requires manual conversion and correction of verticality, which is prone to calculation errors and is cumbersome, and cannot meet the requirements of modern engineering for fast and efficient construction.

[0029] Therefore, with the increasing demands of construction projects, especially the requirements for high precision and high efficiency, the traditional plumb line method has gradually shown its limitations, and a new verticality testing device is urgently needed to solve these problems. Please see Figure 1 This utility model discloses a verticality detection device for building formwork, comprising: a device body 1, a measuring point assembly 2, an attitude detection unit 3, and a processing unit (not shown in the figure).

[0030] Two measuring point components 2 are respectively installed on the left and right sides of the main body 1. The measuring point components 2 can extend and retract horizontally and abut against the surface of the building template. The extending ends of the measuring point components 2 are equipped with gaskets 23, which are used to adhere to the surface of the building template. When the gaskets 23 are in contact with the surface of the building template, the spatial posture of the main body 1 is consistent with the spatial posture of the surface of the building template. An attitude detection unit 3, housed within the main body 1, is used to detect the spatial attitude information of the main body 1. A processing unit, electrically connected to the attitude detection unit 3, is used to calculate the verticality measurement result of the building template based on the spatial attitude information.

[0031] Specifically, the spatial attitude information of the main body 1 refers to the angle of deflection of the main body 1 relative to the direction of gravity. Furthermore, by sensing the direction of gravity, the attitude detection unit 3 can measure the angle of deflection (i.e., pitch angle) of the main body 1 in the front-back direction relative to the direction of gravity (vertical direction).

[0032] The verticality measurement results include the inclination angle value of the building formwork and the verticality value of the building formwork (i.e., the linear offset).

[0033] The operator places the equipment near the formwork. By extending and retracting the measuring point components 2 on both sides, the end pads 23 overcome obstacles at the construction site and finally fit tightly against the surface to be measured on the building formwork. At this time, the spatial posture (i.e., tilt angle) of the equipment body 1 is forcibly adjusted to be consistent with the posture of the formwork surface through the rigidly connected measuring point components 2. The posture detection unit 3, housed within the equipment body 1, detects this posture information in real time, and the processing unit receives this information and calculates the measurement result representing the verticality of the formwork.

[0034] This verticality testing device for building formwork uses a shim 23 as a measurement reference point. By setting two retractable measuring point components 2, the shim 23, serving as the measurement reference point, can bypass obstacles and directly contact the surface of the building formwork. When the shim 23 is in contact with the surface of the building formwork, its spatial orientation is consistent with that of the formwork; that is, the shim 23 and the surface of the formwork are on the same plane, thus ensuring that the spatial orientation of the device body 1 is consistent with that of the formwork surface. At this point, by detecting the spatial orientation information of the device body 1, the spatial orientation information of the formwork surface can be obtained, and the verticality measurement result of the building formwork can be calculated based on this spatial orientation information.

[0035] In summary, this building formwork verticality testing equipment can conveniently test the verticality of building formwork with obstacles.

[0036] In this embodiment, the measuring point assembly 2 includes a slide rail 21 and a slider 22. The slide rail 21 is rigidly installed on the outer wall of the main body 1 of the equipment. The slide rail 21 extends in the horizontal direction. The slider 22 is connected to the slide rail 21 and can slide along the extension direction of the slide rail 21. The end of the slider 22 near the building template is a telescopic end.

[0037] By manually pushing the slider 22, it can be moved along the horizontal slide rail 21, thereby causing the end pad 23 to move closer to or further away from the template surface, achieving telescopic adjustment. The rigid installation of the slide rail 21 ensures directional stability during adjustment.

[0038] The slide rail 21 and the sliding component 22 have smooth structural movement, are easy to process and operate, and can ensure the stability of attitude transmission.

[0039] Furthermore, the measuring point assembly 2 also includes a locking unit (not shown in the figure), which is used to lock the slider 22 at any position on the slide rail 21.

[0040] Specifically, when the slider 22 moves to the appropriate position and the pad 23 fits against the template, the operator activates the locking unit to fix the relative position of the slider 22 and the slide rail 21, preventing accidental sliding during use.

[0041] Clearly, the locking unit can greatly enhance the stability and reliability of the equipment during the measurement process. Specifically, it ensures that the mechanical connection length from the gasket 23 to the main body 1 remains constant at the moment of measurement, preventing measurement errors caused by accidental retraction or extension of the measuring point and guaranteeing the accuracy of the measurement results.

[0042] Optionally, the locking unit can be a helical telescopic rod or an elastic locking structure.

[0043] In some embodiments, a spiral telescopic rod can be selected as both an adjustment unit and a locking unit. The operator rotates the screw, directly pushing the sliding member 22 to extend or retract via the threaded transmission. The self-locking characteristic of the thread naturally achieves locking at any position. The spiral telescopic rod allows for stepless adjustment with high precision.

[0044] In another embodiment, an elastic locking structure can be directly used as the locking unit. The elastic locking structure includes an elastic locking pin and multiple predetermined holes disposed on the slide rail 21. The multiple predetermined holes are arranged at intervals along the sliding extension direction. During operation, the operator first pulls up the elastic locking pin, and then moves the sliding member 22 to the predetermined hole. The locking pin springs into the hole under the action of the spring, achieving rapid positioning and locking. The elastic locking structure enables rapid positioning and is convenient to operate.

[0045] In this embodiment, the gasket 23 is a rectangular gasket 23. The rectangular gasket 23 has a larger contact area and better torsional stability. This can more effectively compensate for minor unevenness on the template surface, ensuring that the plane of the gasket 23 is parallel to the template surface to the maximum extent, thereby more accurately transmitting the template's posture to the device body 1.

[0046] Furthermore, the gasket 23 is made of a soft rubber material. The soft rubber gasket 23 undergoes slight deformation under pressure, fully filling the tiny gaps between itself and the template surface to ensure stable contact between the gasket 23 and the contact surface.

[0047] In this embodiment, the attitude detection unit 3 is an IMU (Inertial Measurement Unit), which includes a gyroscope and an accelerometer.

[0048] The accelerometer in the IMU (Inertial Measurement Unit) provides an absolute gravitational direction reference when the device is stationary, used to measure static tilt angles; the gyroscope continuously tracks changes in the device's angular velocity, used for dynamic angle tracking. The data from both can be fused using existing filtering algorithms (such as Kalman filtering).

[0049] The IMU (Inertial Measurement Unit) can be a commercially available IMU sensor, model ICM-20602, manufactured by InvenSense. In this embodiment, the device also includes a display unit (not shown in the figure). The display unit is installed on the outer wall of the device body 1 and is electrically connected to the processing unit for displaying the verticality measurement results.

[0050] Specifically, the display unit can use a conventional commercially available display screen, and the processing unit can use a commercially available main control chip (such as an ARM Cortex-M series microcontroller).

[0051] In this embodiment, the device also includes an auxiliary fixing mechanism, which is installed on the main body 1 of the device. The auxiliary fixing mechanism (not shown in the figure) is used to temporarily fix the main body 1 of the device to the building template or its supporting structure.

[0052] Specifically, the auxiliary fixing mechanism can be in the form of magnetic adsorption or mechanical clamps, which temporarily fix the main body of the equipment 1 to the template or its steel keel, so that the operator does not need to hold the equipment all the time.

[0053] The following is a further description of the verticality testing equipment for the formwork of this building: This equipment is used for verticality detection during the construction of vertical formwork for shear walls and columns. It aims to solve the problems of inaccurate measurement, inconvenient operation, and difficulty in adapting to complex construction environments associated with traditional plumb line methods.

[0054] The verticality testing device of the present invention includes a main frame (i.e., the device body 1 mentioned above), a retractable measuring point assembly 2 (i.e., the measuring point assembly 2 mentioned above), a rectangular pad 23 assembly (i.e., the pad 23 mentioned above), a gyroscope detection module (i.e., the attitude detection unit 3 mentioned above), a digital display module (i.e., the display unit mentioned above), a power supply and control unit, and an auxiliary fixing mechanism. The overall structure is a portable testing device that can be held by a single person or attached to the template surface by magnetic force / clamp.

[0055] The main body 1 of the equipment has a set of retractable measuring points on each side. Each set of measuring points is connected to the main body via a slide rail 21, and its length is adjusted using a spiral telescopic rod or an elastic locking structure. The length of the measuring points can be freely adjusted according to the template size, ranging from 100mm to 600mm, ensuring that the equipment can adapt to template surfaces of different widths and heights.

[0056] Each measuring point is equipped with a rectangular pad 23 at its end. The pad 23 is made of soft rubber material, which serves two purposes: firstly, it ensures close contact with the template surface, avoiding the influence of minor unevenness on the template surface on the measurement results; secondly, it also acts as a shock absorber and protects the equipment. The measuring point is supported by an elastic support system, which generates a certain preload when it is attached to the template, ensuring that the measuring point is stably fixed at the measurement position.

[0057] The device incorporates a high-precision gyroscope module, which is mounted in the center of the main frame, aligning with the overall vertical orientation of the device. The gyroscope acquires real-time information on the device's angle relative to the ground, achieving a measurement accuracy within ±0.01°.

[0058] The gyroscope continuously tracks the device's attitude through a built-in sensor array (such as a three-axis gyroscope + a three-axis accelerometer), and outputs the current vertical angle deviation after calculation by the main control chip.

[0059] The real-time data output by the gyroscope is converted into visual digital information by a digital signal processor and displayed on the LCD or LED screen on the front of the device. The displayed content includes the current vertical angle (in degrees), whether it deviates from the design value (distinguished by green / yellow / red indicator lights), and information on historical measurement data cache.

[0060] In addition, the module has a built-in unit conversion function, which supports the conversion of angles into millimeter offsets (based on the set height), making it easy for on-site technicians to directly determine whether the template needs to be adjusted based on the measurement results.

[0061] The device is powered by a built-in rechargeable lithium battery with a capacity of over 2000mAh, supporting continuous operation for more than 6 hours. The control unit includes a main control chip, a data processing chip, and a power management module, and is equipped with a power switch, reset button, and settings button for convenient user operation and data reset.

[0062] The device also features a USB-C interface for data export and software upgrades, and some models can be equipped with a Bluetooth module for wireless data synchronization.

[0063] To enhance the stability of the equipment during the testing process, this device is also designed with optional magnetic bases or clamping systems. The magnetic base is suitable for templates with reinforced steel frames, providing a secure hold; the clamping system, secured to both sides of the template via spiral clamping arms, is suitable for wooden templates or non-ferromagnetic templates. This structure further improves the equipment's anti-interference capability during use, ensuring stable data output.

[0064] The usage procedure for this device is as follows: Start the device and complete the initial calibration; Place the device on the template surface to be tested, and adjust the measuring points to ensure they are in close contact with the template. Ensure that the rectangular shims 23 are evenly pressed against the template surface; The gyroscope begins collecting data and displays the vertical angle in real time. If the deviation exceeds the preset range, the display screen will issue an alarm. After the test is completed, the data can be saved and an analysis report can be exported.

[0065] In summary, the specific improvements to this equipment and the resulting beneficial effects include the following aspects: 1. Scalable Measuring Point Design: Traditional verticality testing methods typically rely on fixed measuring tools and struggle to adapt to changes in complex construction sites. To overcome this problem, the device of this invention features a scalable measuring point structure. Through the telescopic device, the measuring point can be adjusted according to different construction environments, easily adapting to various complex conditions, such as confined spaces or construction sites with obstacles. This design not only improves the applicability of the device but also simplifies the operation process, avoiding measurement errors caused by the inflexible adjustment of the device's position in traditional methods.

[0066] 2. Rectangular shim 23 installation: To further improve measurement accuracy, a rectangular shim 23 is installed at the end of each measuring point. The rectangular shim 23 design ensures that the measuring point and the template are in parallel contact, eliminating errors caused by uneven template surface or uneven contact of measuring points. This design greatly improves the accuracy of verticality detection and ensures the reliability of measurement results.

[0067] Each measuring point is equipped with a rectangular pad 23 at its end. The pad 23 is made of soft rubber material, which serves two purposes: firstly, it ensures close contact with the template surface, avoiding the influence of minor unevenness on the template surface on the measurement results; secondly, it also acts as a shock absorber and protects the equipment. The measuring point is supported by an elastic support system, which generates a certain preload when it is attached to the template, ensuring that the measuring point is stably fixed at the measurement position.

[0068] 3. Combination of Gyroscope and Digital Display: Traditional methods of verticality testing often rely on manual calculations and conversions, which are cumbersome and prone to errors. To address this issue, this device is equipped with a gyroscope and digital display. The gyroscope collects real-time angle change data from the device, and combined with the digital display screen, automatically displays the measurement results and performs real-time conversions. This design not only improves measurement accuracy but also significantly increases operational efficiency, avoiding the tedious manual calculations required in traditional methods, allowing construction personnel to quickly obtain verticality measurement results.

[0069] The real-time data output by the gyroscope is converted into visual digital information by a digital signal processor and displayed on the LCD or LED screen on the front of the device. The displayed content includes the current vertical angle (in degrees), whether it deviates from the design value (distinguished by green / yellow / red indicator lights), and information on historical measurement data cache.

[0070] In addition, the module has a built-in unit conversion function, which supports the conversion of angles into millimeter offsets (based on the set height), making it easy for on-site technicians to directly determine whether the template needs to be adjusted based on the measurement results.

[0071] 4. Adaptability to complex construction environments: The extendable design of this equipment allows for flexible adjustment on construction sites with obstacles, avoiding the limitations of traditional plumb line methods that are restricted by space and site conditions. The equipment's design ensures its rapid adaptation to various environments, avoiding limitations imposed on its use during on-site construction.

[0072] 5. Simplified Operation and Efficient Workflow: This equipment simplifies the verticality measurement process through its automated and intelligent design. Operation is simple; users merely place the device on one side of the template, adjust it to the appropriate position using the telescopic device, and the gyroscope automatically performs verticality detection. The digital display shows the results in real time, eliminating the need for manual calculations and repeated adjustments, significantly improving construction efficiency. Furthermore, the automated conversion function eliminates human error, improving construction quality. It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
