Description

  The present invention relates to a concrete curing control system.

  Mass concrete, which is a concrete structure, is known as a concrete having a large minimum dimension of a member cross section and a high possibility of cracking due to a temperature rise due to a hydration reaction of cement. In particular, various methods have been used as measures against cracks caused by a temperature difference between a central portion due to heat of hydration and a peripheral portion including the surface of the mass concrete, and cracks due to drying shrinkage.

  For example, there is a concrete curing management system in which a curing enclosure is provided around a concrete structure, and the temperature in the curing enclosure is controlled based on a thermal stress analysis to prevent cracks. This system performs a preliminary analysis based on a temperature analysis, a stress analysis, and an airflow analysis before concrete placement to calculate a temporary management reference value. Then, by performing a last-minute analysis based on the actually measured value from the temperature and humidity measurement device and correcting the management reference value in accordance with the actually measured value to determine the management reference value, it is possible to perform curing management according to the current situation. (For example, see Patent Document 1).

JP 2013-252983 A

  It is important to control the temperature in concrete curing by gradually lowering the temperature inside the curing enclosure and finally controlling so that the difference between the outside air temperature and the concrete temperature is almost eliminated. That is, within the curing period, gradually reducing the curing temperature and the curing period based on the curing temperature is a factor that shortens the curing period and enables efficient curing control.

  However, the above technique only determines that a control reference value based on an actually measured value is determined based on the pre-analysis and the immediately preceding analysis, and that the temperature and humidity are controlled based on the control reference value. It is not a configuration in which the curing period by temperature is changed stepwise. Therefore, with a single control using a fixed management reference value (or a management reference that varies according to time series), efficient curing management cannot be performed, and the curing period cannot be shortened.

  In addition, the above technique is configured to obtain an accurate measured value by performing airflow analysis in addition to temperature analysis and stress analysis. However, in order to perform control based on such analysis, a blower, a humidifier, a device and a system for controlling the device, and the like are required, so that costs are increased and installation work of a large number of devices is troublesome.

<System configuration>
Hereinafter, an embodiment of a concrete curing control system according to the present invention will be described. FIG. 1 is a diagram showing a schematic configuration of a concrete curing control system 1 according to an embodiment of the present invention.

  The concrete curing control system 1 of the present invention is a system in which a curing enclosure 3 is installed at a place where a concrete structure 2 is cast, and curing inside the curing enclosure 3 is controlled based on a curing management schedule.

  The curing control system 1 is specifically configured to control the curing of the concrete structure 2 by the measurement management unit 4, the temperature control unit 5, and the curing control device 6.

  The concrete structure 2 of the present embodiment is mass concrete, for example, footing. Although the shape of the concrete structure 2 is schematically shown as a rectangular shape, the shape is not limited to this and may be another shape. Then, after the concrete is cast, the outer peripheral surface of the concrete structure 2 is sprayed or humidified after the frame is removed. The outer peripheral surface after the sprinkling or humidification is covered with a plastic film material 20 wound and covered. By setting the state, an environment in which so-called watering curing and sealing curing are used in combination is provided. This is to prevent the surface of the concrete structure from drying.

  The film material 20 is preferably coated so as to have a thickness of 0.01 mm to 1 mm. It has been confirmed that by wrapping the film material 20 around the outer peripheral surface of the concrete structure as described above, the humidity of the concrete structure 2 can be kept substantially constant, and the cracks due to drying can be reliably prevented by the above configuration. Can be. Then, in order to prevent cracks due to drying as in the related art, a humidifier or a device or a system for controlling the humidifier is not required, which is economical.

  The measurement management unit 4 includes an indoor temperature measuring device 41 arranged inside the curing enclosure 3 for measuring the outside air temperature, an outdoor temperature measuring device arranged outside the curing enclosure 3 for measuring the outdoor temperature, and concrete. It has a function of acquiring (accumulating) each measurement information from the concrete temperature measuring device 43 for measuring the temperature of the concrete, and transmitting the respective measurement information to the curing control device 6.

  Each of the temperature measuring devices 41 and 42 is, for example, a temperature sensor. In the illustrated example, one is provided, but a plurality of temperature measuring devices may be provided at a predetermined location. The predetermined location differs depending on the shape and structure of the concrete structure, but is installed in such a number and arrangement that the outside air temperature and the temperature in the curing enclosure 3 can be accurately measured.

  The temperature measuring device 43 for measuring the temperature of the concrete is a temperature sensor, and a plurality of the temperature measuring devices 43 can be installed in different places. For example, it can be buried in advance in the concrete structure 2 as one installation location, and can be installed at a predetermined position on the outer peripheral surface of the concrete structure as another installation location. Then, the internal temperature and the external temperature of the concrete structure 2 can be measured. Incidentally, in the present embodiment, a case where the concrete structure 2 is installed on the outer peripheral surface is shown.

  The temperature control unit 5 has a function of controlling operations such as stopping and operating the heater 50 arranged in the curing enclosure 3. In particular, as will be described later, on / off control of the heater 50 is performed based on a control signal transmitted from the curing control device 6.

  The heater 50 is, for example, a jet heater, and two heaters are mounted in the illustrated example, but this is not a limitation. The number is not limited as long as it is a number and an arrangement in which warm air hits the entire concrete structure uniformly. In order to uniformly apply the warm air from the heater 50 to the outer peripheral wall surface of the concrete structure 2, it is preferable that a perforated air duct is installed on the outer peripheral portion of the concrete structure 2.

  The above-mentioned curing control device 6 performs a preliminary analysis by three-dimensional finite element method analysis to calculate a curing management schedule, acquires actual measured values of each temperature information acquired from the measurement management unit 4, and It has a function of transmitting a control signal based on the temperature to the temperature control unit 5 to control the temperature of the concrete structure 2 in the curing enclosure 3.

  The curing control device 6 includes an analysis unit 61 that calculates a curing management schedule by three-dimensional finite element analysis, and a communication unit 62 that exchanges information with another terminal. The curing control device 6 is a so-called computer 6 and also has various functional units provided in a normal computer, and includes various kinds of necessary information such as past weather data, structure information, stress analysis, and the like. It is provided with storage means for storing software and the like.

  The analysis section 61 has a function of calculating a curing management schedule in which the curing temperature of the concrete structure 2 and the duration of the curing temperature are changed stepwise. The analysis unit 61 calculates the curing management schedule by the three-dimensional finite element method analysis as described above. More specifically, the curing management schedule requires that the temperature of the concrete structure 2 be maintained at a predetermined curing temperature so as not to be adversely affected by a sudden drop in the outside air temperature, and that the heat radiation be appropriately promoted. For the purpose, it is calculated by a method of gradually lowering the curing temperature.

  The purpose of calculating the curing management schedule is to control the temperature in concrete curing as described above, by gradually lowering the temperature in the curing enclosure 3 and finally determining the difference between the outside air temperature and the temperature of the concrete structure 2. It is known that it is important to perform control so as to eliminate it. That is, within the curing period, gradually reducing the curing temperature and the curing period based on the curing temperature is an element that can shorten the curing period and achieve efficient curing control.

Therefore, the analysis unit 61 sets a plurality of curing temperatures and a curing period based on the respective curing temperatures, and calculates the curing management schedule in which the plurality of curing temperatures are reduced stepwise. That is, this is a method of setting the curing temperature and the curing period in a plurality of stages.
For example, as shown in FIG. 3, in the first stage A, the curing temperature is set to 23 ° C., and the curing period is set to the first to seventh days. In the second stage B, the curing temperature was set to 18 ° C., and the curing period was set to 8 to 15 days. In the third stage C (final stage), the curing temperature was set to 13 ° C., and the curing period was set to 16 days to 18 days. In the case of FIG. 3, the curing period and the curing temperature are divided into three stages, and the schedule for gradually lowering (falling) the curing temperature is calculated. In particular, during the curing period of the third stage C (final stage), a schedule is gradually calculated from the curing temperature of 18 ° C. of the second stage B to 13 ° C., which is the outside temperature, for example.

  In the curing management schedule, if the difference between the outside air temperature of the temperature measuring device 42 and the temperature of the concrete structure 2 of the temperature measuring device 43 falls within the management value at the end of the third stage C (final stage). Complete.

  The communication unit 62 has a function of transmitting warning information to another terminal when the measurement information obtained from the measurement management unit 4 exceeds a specified value. The warning information is automatically sent to a preset terminal by e-mail or the like. The condition for transmitting the warning information is, for example, a case where the temperature in the curing enclosure 3 is higher than the temperature of the concrete structure 2 and exceeds a specified value. These conditions and specified values are set in the storage means in advance.

<Curing control procedure>
Next, the flow of the curing control of the concrete curing control system 1 according to the present invention will be described with reference to the flowchart of FIG.

  In the present embodiment, for example, a case where the present system is applied to a footing having a thickness of about 1 m or more as a concrete structure 2 will be described with occasional specific numerical values.

  First, in step (hereinafter simply abbreviated as ST) 1, the manager inputs construction conditions using input means or the like added to the computer of the curing control device 6. The construction conditions include, for example, the type of concrete structure (footing, box culvert, caisson, etc.), dimensions of the concrete structure, various conditions, material information, expected outside air temperature, and the like.

  In ST2, a pre-analysis is performed based on the input construction conditions. The pre-analysis step of ST2 will be specifically described with reference to the flowchart shown in FIG. The pre-analysis is specifically a thermal stress analysis using a three-dimensional finite element method. By this three-dimensional analysis, advanced analysis is performed according to various conditions related to concrete curing management, such as the type and shape of the concrete structure input in ST1. The three-dimensional analysis is different from the two-dimensional analysis in which the depth of the structure is assumed to be uniform because the shape and the construction conditions of the structure are three-dimensionally modeled. For this reason, the temperature and stress generated in the actual structure are faithfully reproduced, the case where the curing temperature and the curing period are changed is evaluated by analysis, and the optimal curing condition is calculated.

  First, in ST21 of FIG. 4, a target value of the crack index is set. The check of cracks that are likely to occur due to the hydration of cement is performed based on the magnitude of the crack index. In other words, setting the target value of the crack index determines the safety factor against the occurrence of cracks, such as whether to prevent cracks or to allow cracks but limit the width of cracks.

  Next, in ST22, a surface where cracks may occur is set as a target surface on which curing control is performed. Here, the surface where it is not necessary to perform the curing control may be excluded from the target.

  Next, in ST23, a curing temperature and a curing period in a general construction method are input. Then, a temperature stress analysis is performed in ST24. The thermal stress analysis is an analysis using the three-dimensional finite element method as described above.

  In ST25, it is confirmed whether or not the target value of the crack index has been satisfied. If satisfied (YES), the curing temperature and the curing period set in ST23 are determined (ST26). However, since the curing temperature and the curing period in the general construction method set in ST23 are methods in which no special temperature control is performed, the curing temperature is set to the same as the outside temperature, and the curing period is a general plywood or The period during which the steel formwork remains is set (temporarily set). When using a general plywood or steel formwork, heat dissipation of concrete temperature is promoted due to a decrease in outside air temperature, and the temperature drops sharply. Some structures do not satisfy the index. If the crack index is not satisfied in ST24 (NO), the process returns to ST23, and the curing temperature and the curing period depending on the curing temperature are reset, and the operations from ST23 to ST25 are performed until the target crack index is satisfied. Repeat by trial and error. Based on the analysis value calculated by the pre-analysis, the setting of the subsequent curing management schedule is performed.

  Returning to FIG. 2, in ST3, the analysis unit 61 of the curing control device 6 calculates and determines a curing management schedule based on the analysis value of the pre-analysis. As described above, the curing management schedule sets a plurality of curing temperatures and the curing periods based on the respective curing temperatures, and calculates the curing management schedule in which the curing temperature is reduced stepwise. That is, the curing management schedule is calculated using the set values of the curing temperature and the curing period that satisfy the target crack index in the analysis values of the above-described preliminary analysis.

  An example of the curing management schedule is shown as an image in FIG. This curing management schedule is a footing with a thickness of about 1 m or more, and the construction time is assumed to be in early April. The curing management schedule YS in FIG. 3 is divided into three stages, and is set so that the curing temperature decreases in order. In the first stage A, the curing temperature is 23 ° C., and the curing period is from the first day to the seventh day. In the second stage B, the curing temperature is 18 ° C., and the curing period is from day 8 to day 15. In the third stage C, the curing period is from the 16th day to the 18th day, and the curing temperature is a schedule in which the temperature of the concrete structure 2 is gradually decreased so as to gradually approach the outside temperature of 13 ° C. Of course, the final stage, the third stage C, may be further divided into one day, and may be lowered little by little, such as 1.5 ° C. This point is appropriately set in accordance with the season, the type and shape of the concrete structure 2, and the like. In short, the most efficient (shorter curing period) curing management schedule is calculated using three-dimensional finite element analysis.

  Next, in ST4, concrete is cast with contents that match the construction conditions input in ST1, and a concrete structure 2 is constructed.

  After the above operation, the curing control device 6 acquires the measurement information from the measurement management unit 4 and starts the curing control (ST5). At this time, the measurement management unit 4 transmits the measurement information from the indoor temperature measuring device 41, the outdoor temperature measuring device 42, and the concrete temperature measuring device 43 to the curing control device 6.

  In ST6, the curing control device 6 sends a control signal (ON / OFF) of the heater 50 to the temperature control unit 5 based on each measurement information from the measurement management unit 4 and the curing management schedule set in ST3. Send to control the curing temperature. Incidentally, the on / off control of the heater 50 may be set to operate when the temperature exceeds, for example, ± 3 ° C. with respect to the curing temperature set in the curing management schedule. In this example, when the set curing temperature is 23 ° C., the operation of the heater 50 is stopped when the temperature reaches 26 ° C., and the operation of the heater starts when the temperature reaches 20 ° C.

  The "control of curing temperature" step of ST6 will be specifically described with reference to the flowchart of FIG. Hereinafter, a description will be given by taking as an example a curing management schedule YS having contents divided into three stages from the first stage A to the third stage C (final stage) shown in FIG. ST60 to ST63 of the control flow shown in FIG. 5 are repeated for each set stage. Therefore, immediately after the start, first, the number of stages “N” = “1” stages is given.

  In ST60, the curing control device 6 first determines whether the curing temperature of the first stage A (23 ° C. in FIG. 3) has been achieved. If not achieved (NO), the curing control device 6 transmits a control signal to the temperature control unit 5 in ST61 to perform on / off control of the heater 50 to achieve the curing temperature. The case where the curing temperature is not achieved is, for example, a case where the curing temperature is not within ± 3 ° C. of the curing temperature set in the first stage A. In the case of FIG. 3, the temperature is 23 ° C. (± 3 ° C.).

  In ST60, when the curing temperature of the first stage A has been achieved (YES), the curing control device 6 determines whether or not it is within the curing period of the first stage A in ST62. This can be confirmed by calendar information or the like of the computer of the curing control device 6. The curing period of the first stage A in FIG. 3 is up to the seventh day. If it is within the curing period of the first stage A (YES), the process returns to ST60 and the curing temperature control steps (ST60 to ST62) are repeated until the curing period elapses.

  In ST62, when the curing period of one stage A has passed (NO), the curing control device 6 determines whether the number of stages “N” is the final stage (ST63). At this time, the number of stages “N” is “1”, and in the case of FIG. 3, the number of stages is “3”, so it is not the final stage (NO). Then, the curing control device 6 gives “N = N + 1” as the number of steps, and repeats the second step of controlling the curing temperature in ST60 to ST62. Since the steps after the second step have been described above, they will not be particularly described, but in the case of the second step B in FIG. 3, the curing temperature is 18 ° C. (± 3 ° C.) during the 8 to 15 days of the curing period. Curing control is performed so that

  If N is the final stage (three stages C in the case of FIG. 3) in ST63 (YES), the curing control device 6 achieves the curing period and the curing temperature set in the final stage (three stages C). Control is performed. At this time, it is determined whether the difference between the temperature of the concrete structure 2 and the outside air temperature is within the control value (ST64).

  In the final stage, as shown in FIG. 3, by the final day of the curing period (18th day), the curing temperature (18 ° C.) of the previous stage (two stages B) gradually approaches the outside temperature (13 ° C.). The control for lowering the curing temperature is performed. That is, the curing control device 6 acquires the measurement information acquired from the temperature measuring device 42 for measuring the temperature of the outside air temperature and the measurement information acquired from the temperature measuring device 43 for measuring the temperature of the concrete, and obtains the temperature of the concrete. Is transmitted to the temperature control unit 5 so as to gradually reduce the temperature to the outside air temperature.

  Controlling to approach the outside temperature means reducing the curing temperature so that the difference between the temperature of the concrete structure 2 and the outside temperature falls within the management value.

  In ST64, when the difference between the temperature of the concrete structure 2 and the outside air temperature is outside the control value (NO), the curing control device 6 determines whether it is necessary to extend the final curing period in ST65, and extends the curing period. If it is necessary to do so, the analyzer 61 changes (re-sets) the curing management schedule. In particular, the curing period of the final stage (3rd stage C) is corrected, and accordingly, the schedule for lowering the curing temperature is also changed. This is a step to cope with a case where, for example, an unexpected outside air temperature results in a considerable difference in temperature from the concrete structure 2 and it is difficult with the set curing temperature and curing period. Therefore, the curing control device 6 determines a necessary curing period using information on a difference between the temperature of the concrete structure 2 and the outside air temperature.

After the step of ST65, the control signal (ON of the heater 50 to the temperature control unit 5 is sent to the temperature control unit 5 based on the measurement information from the measurement management unit 4 and the curing management schedule (including the modified curing management schedule) in ST66.・ Off) is transmitted to control the curing temperature in the final stage.
ST66 is a setting in which the curing control of ST61 is divided more finely, and conceptually performs the same curing control as ST61.

  In ST64, when the difference between the temperature of the concrete structure 2 and the outside air temperature is within the control value (YES), the curing control device 6 determines in ST67 whether or not it is within the final stage (three stages) of the curing period. In the case of FIG. 3, the curing period in the final stage is 18 days (eyes). Further, in ST65, when the curing management schedule is changed, it is determined whether or not it is within the changed curing period.

  In ST67, if the curing period is within the final stage (YES), the process returns to ST64 and waits until the curing period has passed while controlling the difference from the outside air temperature to be within the management value. If the final curing period has passed in ST67 (NO), the “control of curing temperature” step ends. This means that the “curing temperature control” step of ST6 in FIG. 2 has been completed, and the curing control by the concrete curing control system 1 has been completed.

  By the way, when the measurement information obtained from the measurement management unit 4 exceeds the specified value after the concrete placement in ST4, the curing control device 6 transmits the warning information to another terminal of the manager or the like via the communication unit 62. Send automatically. That is, a configuration in which warning information is transmitted when each temperature information from the indoor temperature measuring device 41, the outdoor temperature measuring device 42, and the concrete temperature measuring device 43 becomes a dangerous value or a non-specified value. It is.

  Incidentally, from the temperature information from the indoor temperature measuring device 41, the outdoor temperature measuring device 42, and the concrete temperature measuring device 43, the indoor temperature, the outside air temperature, and the temperature of the concrete structure 2 can be detected. Therefore, the difference between the temperatures may be calculated, and the warning information may be transmitted even when the difference exceeds the specified value. For example, if there is too much difference between the room temperature and the temperature of the concrete structure 2, it is considered that there is a failure in the curing enclosure or a failure of the temperature measuring instrument, and it is necessary to take immediate action. Of course, there are other reasons for exceeding the specified value.

<Summary>
As described above, the concrete curing control system according to the present embodiment is configured to calculate the most efficient curing management schedule using three-dimensional finite element method analysis. That is, since a plurality of curing temperatures and a curing period based on each of the curing temperatures are set, and the curing management schedule in which the curing temperature is reduced stepwise is calculated, the conventional curing period is reduced by, for example, 10% to 15%. %.

  As described above, it is known that it is important to control the temperature in the concrete curing so as to finally eliminate the difference between the outside air temperature and the temperature of the concrete structure 2.

  The curing management schedule by the concrete curing control system of the present embodiment is configured such that at the end of the final stage, control is performed to gradually lower the temperature of the concrete so as to approach the outside air temperature. Furthermore, after confirming whether the difference between the outside air temperature and the temperature of the concrete structure 2 is within the control value, curing is completed. Therefore, it is possible to reliably prevent cracks and contribute to the construction of a high-quality concrete structure 2.

Watering or humidification is performed on the outer peripheral surface of the concrete structure 2 to be cured, and a plastic film material 20 is wound around the outer peripheral surface after watering or humidification to cover the outer peripheral surface, thereby forming a closed state. The environment where both watering curing and sealing curing are used is prepared. Therefore, it is possible to prevent the surface of the concrete structure from cracking due to drying. In addition, there is no need to install humidifiers or devices or systems that control the equipment, so it is necessary to prevent large-scale systems, reduce costs and increase the efficiency of equipment installation work.
