Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a remote monitoring system for the quality of formwork engineering. Background Art

[0002] In the construction of reinforced concrete projects, before pouring the reinforced concrete structure, it is necessary to set out and erect the formwork according to the design requirements, so that the plane position, elevation, geometric dimensions, etc. of the structure meet the structural design requirements and reach the structural design strength after the concrete pouring is completed. According to different formwork forms, it can be divided into turnover formwork, fixed formwork, integral formwork, etc. In the process of formwork installation, the general construction process of formwork installation is: construction preparation - formwork assembly - measurement and setting out - formwork installation - calibration and reinforcement - formwork acceptance - concrete pouring - formwork removal.

[0003] After the initial installation of the formwork, it is necessary to calibrate and reinforce the formwork. For the internal dimensions of formwork structures such as foundations, slabs, beams, and columns, it is usually inspected by using a ruler. The above inspection methods are greatly affected by human factors and have low efficiency. There are also problems such as difficult operation in some formwork positions. In addition, after the formwork acceptance is completed, during the concrete pouring, the formwork is affected by problems such as the internal pressure load of the concrete, interference from external construction personnel, and interference from construction machinery and equipment, which affect the formwork installation quality and thus affect the finally poured concrete structure. Therefore, at present, the quality control of formwork engineering during the concrete pouring process needs to be improved and perfected. Summary of the Utility Model

[0004] The purpose of the patent of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a remote monitoring system for the quality of formwork engineering, which can reduce the human influence factors during the formwork inspection and calibration process, improve the formwork inspection and calibration efficiency, and increase the operability of the inspection; during the concrete pouring process, improve the quality control of formwork engineering and achieve the process control of formwork engineering quality during the concrete pouring.

[0005] The technical solution adopted by this patent is as follows: A remote monitoring system for the quality of formwork engineering includes at least one integrated terminal and a server. The integrated terminal includes several distance sensors and at least one sound and light alarm. The distance sensors are detachably installed on one of the formworks and cooperate with the target mirrors installed on the other opposite formwork to measure the distance between the two opposite formworks. The ranging data of the distance sensors is sent to the server. After the server processes the ranging data, it is stored and processed, and when the ranging data exceeds the threshold, an alarm signal is triggered and sent to the sound and light alarm to achieve an alarm.

[0006] Preferably, the server includes a processor, an input module, a storage module, a visualization module, and a communication module that are electrically connected thereto; the input module is used to input the template and the preset data of the integrated terminal, the storage module is used to store the preset data and the ranging data, the processor module is used to process the ranging data and compare it with the preset data of the template to determine whether it exceeds the threshold, the visualization module is used to display the status of the integrated terminal and the server, and the communication module communicates with the distance sensor and the audible and visual alarm device by wire or wirelessly.

[0007] Preferably, the distance sensor is arranged horizontally or vertically.

[0008] Preferably, each distance sensor is equipped with a corresponding audible and visual alarm device. When the ranging data of any distance sensor exceeds the threshold, an alarm signal is triggered and sent to the corresponding visual alarm device to achieve an alarm.

[0009] Preferably, a mobile terminal is further included, which communicates wirelessly with the server and is used to receive the alarm information sent by the server.

[0015] (5) Analysis and discrimination; start the integrated terminal to conduct real-time remote monitoring of the formwork engineering. The processor compares the actual measured spacing of the formwork in the formwork information data sent by the integrated terminal with the preset data in step (3).

Detailed Embodiment

[0026] To enable those of ordinary skill in the art to more clearly understand the purpose, technical solution and advantages of the utility model, the following further elaborates the utility model in conjunction with the drawings and embodiments, but the utility model is not limited to the following embodiments.

[0027] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0028] As Figure 1 shown, this embodiment provides a remote monitoring system for the quality of formwork engineering, including an integrated terminal 1 and a server 2. The number of integrated terminals 1 matches the number of groups of formworks 3 to be monitored. Each integrated terminal 1 includes a number of distance sensors 1.1 and at least one acoustic-optic alarm 1.2. Usually, each distance sensor 1.1 is equipped with a corresponding acoustic-optic alarm 1.2. When the ranging data of any distance sensor 1.1 exceeds the threshold, an alarm signal is triggered and sent to the corresponding optical alarm to achieve an alarm. As Figure 3 , Figure 4 shown, the distance sensor 1.1 is detachably installed on the installation position 3.1 of one of the formworks 3 by means of bolts or glue, etc. The installation angle of the distance sensor 1.1 is determined according to the on-site situation of the formwork 3, usually arranged horizontally or vertically. A target mirror 5 is installed on the installation position 3.1 of the other opposite formwork 3. The target mirror 5 is aligned with the detection end of the distance sensor 1.1 and is not blocked by the intermediate steel bar structure 4. The distance sensor 1.1 and the target mirror 5 cooperate to achieve ranging of two opposite formworks 3. The ranging data of the distance sensor 1.1 is sent to the server 2. After processing the ranging data, the server 2 stores and processes it, and triggers an alarm signal to the acoustic-optic alarm 1.2 to achieve an alarm when the ranging data exceeds the threshold. At the same time, the communication module 2.3 also sends the alarm information to a pre-authorized mobile terminal (such as a mobile phone) through the cellular network.

[0029] Specifically, the server 2 includes a processor 2.1 and an input module 2.2, a storage module 2.4, a visualization module 2.5, and a communication module 2.3 that are electrically connected thereto. The input module 2.2 is used to input the preset data of the formwork 3 and the integrated terminal 1, as well as the information of the pre-authorized mobile terminal. The storage module 2.4 is used to store the preset data, the ranging data, and the information of the pre-authorized mobile terminal. The processor 2.1 module is used to process the ranging data and compare it with the preset data of the formwork 3 to determine whether it exceeds the threshold. The visualization module 2.5 can use a display screen or a touch screen and is used to display the status of the integrated terminal 1 and the server 2. The communication module 2.3 communicates with the distance sensor 1.1 and the acoustic-optic alarm 1.2 in a wired or wireless manner (such as data lines, cellular networks, or WIFI, etc.).

[0030] The preset data usually includes basic information such as installation time, template 3 number, model and number of distance sensor 1.1, model and number of audible and visual alarm 1.2, set spacing of template 3, allowable deviation, data acquisition frequency, system error correction, alarm information, etc. The above information is input into the server 2 by the input module 2.2. The recommended accuracy of the distance sensor 1.1 is millimeter level, and conventional infrared distance sensors, ultrasonic distance sensors, etc. can be used.

[0031] During the use process, after the server presets the relevant data, each distance sensor collects the spacing of the corresponding part of the template and transmits it to the server. When the absolute difference of the template spacing ≤ allowable error, the server determines that the quality of the template project is qualified; otherwise, it determines that the quality of the template project is unqualified and sends an alarm signal to the audible and visual alarm supporting the corresponding distance sensor for alarm. The visualization module can display the status of all integrated terminals of the template project, including the preset data of the template and the integrated terminals, the quality qualified status, etc. (for example, green dot + static can be used to represent qualified, and red dot + flashing can be used to represent unqualified). The visualization implementation means of the data and status can adopt the existing technology and will not be introduced in detail here. The data storage module stores and archives the preset data and the ranging data of the distance sensor for convenient later data inspection and call.

[0032] As Figure 2 shown, the remote monitoring method for the quality of the template project provided by the present utility model adopts the above remote monitoring system for the quality of the template project and is carried out according to the following steps:

[0033] (1) Installation preparation

[0034] Before installing the integrated terminal, it is necessary to complete the preparatory work before template installation, that is, complete construction preparation - template assembly - measurement and lofting - template installation, so as to provide the required installation space position for the installation of the integrated terminal.

[0035] (2) Install the integrated terminal

[0036] After the above installation preparation is completed, according to the actual monitoring requirements of the construction site, install the integrated terminal on the template, and the installation method can adopt bolt connection, glue connection, etc. Figure 3 Only install three sets of integrated terminals, and the specific quantity can be adjusted according to the actual on-site requirements such as building level and accuracy requirements. During installation, it is necessary to ensure that the detection end of the distance sensor is aligned with the inner surface of the target mirror and ensure that there are no obstacles blocking the detection path.

[0037] (3) Basic system settings

[0038] After the above integrated terminal is installed, basic settings such as adding the integrated terminal, setting the installation time, setting the device number, inputting the device model, setting the template spacing, setting the allowable deviation, correcting the systematic error, setting the alarm information, and setting the data acquisition frequency are completed on the server side.

[0039] (4) System debugging

[0040] After the above basic system settings are completed, the system needs to be debugged to ensure that the hardware devices of the integrated terminal are normal, the installation is correct, and the data transmission between the integrated terminal and the server is smooth. The accuracy of the distance sensor needs to be calibrated. Use it to measure the fixed-length scale multiple times, record the deviation data between the length data it collects and the actual scale length, and the average value of the deviation data can be used as the systematic error correction value.

[0041] When there are errors in the installation of the integrated terminal hardware and data transmission failures between the integrated terminal and the server, it is necessary to return to step (2) to re-check the installation of the integrated terminal.

[0042] (5) Analysis and discrimination

[0043] After the above system debugging is completed, the system can run formally and can monitor the template project in real time remotely. The processor calculates the difference between the actually measured template spacing in the template information data sent by the integrated terminal and the system-set spacing in step (3). When the absolute difference of the template spacing ≤ the allowable error setting value, it is determined that the quality of the template project is qualified until the monitoring of the concrete pouring ends; otherwise, it is determined that the quality of the template project is unqualified, and an alarm signal is issued, and the visualization module displays the alarm signal (such as "red dot + flashing").

[0044] (6) Sending alarm information

[0045] In the above analysis and discrimination, when it is determined that the quality of the template project is unqualified, the communication module sends an alarm signal (activation instruction) to the audible and visual alarm of the integrated terminal. The audible and visual alarm issues an alarm signal to prompt the relevant quality supervision personnel to correct the unqualified template, and at the same time, it regularly sends alarm information to the mobile terminal pre-set in the "alarm information setting" in step (3).

[0046] (7) Template correction

[0047] After the on-site quality supervision personnel receive the above alarm information, they immediately organize the front-line surveyors and construction workers to correct the unqualified part of the formwork erection quality to ensure the formwork erection quality. When the correction is completed, the absolute difference of the template spacing collected by the distance sensor ≤ the allowable error setting value, the alarm signal is eliminated on the visualization module interface, and the mobile terminal no longer receives the mobile phone alarm information.

[0048] (8) End of monitoring

[0049] After the concrete pouring work of the current formwork project is completed, close the integrated terminal and output the monitoring results, including equipment number, equipment model, monitoring time, formwork spacing, allowable deviation, system correction error, alarm information statistics, etc. The monitoring results can be used as auxiliary materials and basis for the quality acceptance of the formwork project.

[0050] (9) Data storage

[0051] Store the above monitoring results in the storage module of the server. Subsequently, through the visualization module and input module, according to the equipment number or equipment installation time, the monitoring results of the corresponding integrated terminal can be queried.

[0052] The above are only the preferred embodiments of the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
