Description

  The present invention relates to a concrete curing control system.

  Mass concrete as a concrete structure is known as concrete having a large minimum cross-sectional dimension of a member and high risk of cracking due to a temperature increase due to a cement hydration reaction. In particular, various methods have been used as countermeasures against cracks due to temperature differences between the central part due to heat of hydration and the peripheral part including the mass concrete surface 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 temperature stress analysis to prevent cracking. This system performs preliminary analysis based on temperature analysis, stress analysis, and airflow analysis before concrete placement, and calculates a temporary management reference value. Then, it is possible to perform curing management in accordance with the current situation by performing a previous analysis based on the actual measurement value from the temperature and humidity measurement device and correcting the management reference value according to the actual measurement value to determine the management reference value (For example, refer to Patent Document 1).

JP 2013-252983 A

  In temperature management in concrete curing, it is important to control so that the temperature inside the curing enclosure is gradually lowered and finally the difference between the outside temperature and the concrete temperature is almost eliminated. In other words, in the curing period, gradually decreasing the curing temperature and the curing period based on the curing temperature is an element that shortens the curing period and enables efficient curing control.

  However, the above technique only describes that the management reference value based on the actual measurement value is determined by the prior analysis and the immediately preceding analysis, and the temperature and humidity are controlled based on the management reference value. It is not the structure which changes the curing period by temperature stepwise. Therefore, with a single control based on a certain management standard value (or including a management standard that varies with time series), efficient curing management cannot be performed and the curing period cannot be shortened.

  Moreover, the said technique is set as the structure which acquires an exact measured value by performing airflow analysis other than temperature analysis and stress analysis. However, in order to perform control based on such analysis, a blower, a humidifier, and an apparatus or system for controlling the device are required, which increases costs and troublesome installation work of many devices.

<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 placed, and the inside of the curing enclosure 3 is controlled based on a curing management schedule.

  Specifically, the curing control system 1 is 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, such as footing. The shape of the concrete structure 2 is generally rectangular, but is not limited to this and may be other shapes. Then, after the frame is placed after the concrete is placed, the outer peripheral surface of the concrete structure 2 is sprinkled or humidified, and the outer peripheral surface after the sprinkling or humidification is covered with a plastic film material 20 so as to be covered and sealed. By being in a state, an environment in which so-called watering curing and sealing curing are used in combination is prepared. This is to prevent the surface of the concrete structure from drying out.

  The film material 20 is preferably coated so that the thickness is 0.01 mm to 1 mm. As described above, it is confirmed that the humidity of the concrete structure 2 can be kept almost constant by winding the film material 20 around the outer peripheral surface of the concrete structure, and cracking due to drying can be reliably prevented by the above configuration. Can do. Then, in order to prevent cracking due to drying as in the prior art, a humidifier and a device or system for controlling the humidifier are not necessary, which is economical.

  The measurement management unit 4 includes an indoor temperature measuring device 41 that measures the outside air temperature arranged in the curing enclosure 3, an outdoor temperature measuring device 42 that measures the outdoor temperature arranged outside the curing enclosure, and concrete. It has a function of acquiring (accumulating) each measurement information from the concrete temperature measuring instrument 43 for measuring the temperature of the concrete and transmitting the measurement information to the curing control device 6.

  The temperature measuring devices 41 and 42 are, for example, temperature sensors, and in the illustrated example, there is one, but a plurality of temperature measuring devices 41 and 42 may be installed at predetermined locations. Although it differs depending on the shape and structure of the concrete structure, the predetermined place is installed with the number and arrangement capable of accurately measuring the outside air temperature and the temperature in the curing enclosure 3.

  Moreover, the temperature measuring instrument 43 that measures the temperature of the concrete is a temperature sensor, and a plurality of them can be installed at different locations. For example, it can be embedded in the concrete structure 2 in advance 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 external temperature of the concrete structure 2 can be measured. Incidentally, in this embodiment, the case where it installed in the outer peripheral surface of the concrete structure 2 was shown.

  The temperature controller 5 described above has a function of controlling operations such as stopping and operation of the heater 50 disposed in the curing enclosure 3. Although it mentions later in particular, 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 restrictive. The number is not limited as long as the number and arrangement of the hot air uniformly hit the entire concrete structure. Moreover, in order to apply the warm air from the heater 50 uniformly to the outer peripheral wall surface of the concrete structure 2, it is preferable to install a perforated air duct on the outer periphery of the concrete structure 2.

  The above-described curing control device 6 calculates a curing management schedule by performing a pre-analysis by a three-dimensional finite element method analysis, acquires an actual measurement value of each temperature information acquired from the measurement management unit 4, and sets the curing management schedule to The control signal based on this is transmitted to the temperature control part 5, and it has the function to control the temperature of the concrete structure 2 in the curing enclosure 3. FIG.

  The curing control device 6 includes an analysis unit 61 that calculates a curing management schedule by three-dimensional finite element method analysis, and a communication unit 62 that exchanges information with other terminals. Further, the curing control device 6 is a so-called computer 6 and also has various functional means provided in a normal computer. Various necessary information such as past meteorological data, structure information, stress analysis, etc. A storage means for storing software and the like is provided.

  The analysis unit 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. As described above, the analysis unit 61 calculates the curing management schedule by the three-dimensional finite element method analysis. More specifically, the curing management schedule is to maintain a predetermined curing temperature so that the temperature of the concrete structure 2 is not adversely affected by a sudden decrease in the outside air temperature, and to appropriately promote heat dissipation. It is calculated by a method of gradually lowering the curing temperature as a purpose.

  The purpose of calculating the curing management schedule is, as described above, in the temperature management in the concrete curing, the temperature in the curing enclosure 3 is gradually lowered, and finally the difference between the outside temperature and the temperature of the concrete structure 2 is calculated. It is known that it is important to control so as to eliminate it. That is, in the curing period, gradually decreasing the curing temperature and the curing period based on the curing temperature is an element that shortens the curing period and enables efficient curing control.

Therefore, the analysis unit 61 sets a plurality of curing temperatures and curing periods based on the respective curing temperatures, and calculates the curing management schedule in which the plurality of curing temperatures are reduced stepwise. In other words, the curing temperature and the curing period are set 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 from the first day to the seventh day. In the second stage B, the curing temperature was set to 18 ° C. and the curing period was from the 8th day to the 15th day. In the third stage C (final stage), the curing temperature was 13 ° C., and the curing period was set from the 16th day to the 18th day. In the case of FIG. 3, the curing period and the curing temperature are divided into three stages, and a schedule for gradually decreasing (decreasing) the curing temperature is calculated. In particular, in the curing period of the third stage C (final stage), a schedule that gradually approaches the curing temperature of the second stage B from 18 ° C. to, for example, 13 ° C., which is the outside air temperature, is calculated.

  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 is within the management value at the final stage of the third stage C (final stage), the curing is performed. To complete.

  The communication unit 62 has a function of transmitting warning information to another terminal when the measurement information acquired 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. As a condition for transmitting the warning information, for example, 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.

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

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

  First, in step (hereinafter simply abbreviated as ST) 1, the manager inputs construction conditions using an 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.), the dimensions of the concrete structure, various conditions, material information, and the expected outside temperature.

  In ST2, a preliminary analysis is performed based on the input construction conditions. The prior analysis step of ST2 will be specifically described with reference to the flowchart shown in FIG. Specifically, the prior analysis is a temperature stress analysis using a three-dimensional finite element method. By this three-dimensional analysis, advanced analysis is performed in accordance with 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 construction conditions of the structure are three-dimensionally modeled in three dimensions. For this reason, the temperature and stress which generate | occur | produce in a real structure are faithfully reproduced, the case where the curing temperature and the curing period were changed is evaluated by analysis, and optimal curing conditions are calculated.

  First, in ST21 of FIG. 4, a target value for the crack index is set. Checking for cracks that are likely to occur due to cement hydration depends on the size of the crack index. That is, setting the target value of the crack index defines a safety factor against the occurrence of cracks, such as preventing cracks or restricting cracks to be allowed but not widened.

  Next, in ST22, a surface that may be cracked is set as a target surface on which curing control is performed. Here, the surface which does not need to perform curing control may be excluded.

  Next, in ST23, a curing temperature and a curing period in a general construction method are input. In step ST24, temperature stress analysis is performed. The temperature 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 is satisfied. If satisfied (YES), the curing temperature and curing period set in ST23 are determined (ST26). However, the curing temperature and curing period in the general construction method set in ST23 is a method in which no special temperature control is performed, so the curing temperature is set to the same as the outside air temperature, and the curing period is a general plywood or The period during which the steel formwork is placed is set (temporary setting). When using a general plywood or steel formwork, the thermal cracking of the concrete temperature is accelerated by a decrease in the outside air temperature and decreases rapidly. Some structures do not satisfy the index. In ST24, if the crack index is not satisfied (NO), return to ST23 to reset the pattern with different curing periods depending on the curing temperature and the curing temperature, and perform the work from ST23 to ST25 until the target crack index is satisfied. Repeat trial and error. Based on the analysis value calculated by this prior analysis, the subsequent curing management schedule is set.

  Returning to FIG. 2, the analysis unit 61 of the curing control device 6 calculates and determines a curing management schedule based on the analysis value of the preliminary analysis in ST3. As described above, the curing management schedule sets a plurality of curing temperatures and curing periods based on the respective curing temperatures, and calculates the curing management schedule in which the curing temperature is lowered stepwise. That is, the curing management schedule is calculated with the setting values of the curing temperature and the curing period that satisfy the target cracking index in the analysis values of the prior 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 the 8th day to the 15th day. The third stage C is a schedule in which the curing period is from the 16th day to the 18th day, and the curing temperature is gradually lowered so that the temperature of the concrete structure 2 gradually approaches the outside air temperature 13 ° C. Of course, the third stage C, which is the final stage, may be further divided into one day, and the temperature may be lowered little by little, such as 1.5 ° C. This point is appropriately set according to the season and the type and shape of the concrete structure 2. In short, the most efficient (short curing period) curing management schedule is calculated using a three-dimensional finite element method analysis.

  Next, in ST4, concrete placement with contents matching the construction conditions input in ST1 is performed, and the concrete structure 2 is constructed.

  After the above operation, the curing control device 6 acquires measurement information from the measurement management unit 4 and starts curing control (ST5). At this time, the measurement management unit 4 transmits each measurement information from the indoor temperature measuring instrument 41, the outdoor temperature measuring instrument 42, and the concrete temperature measuring instrument 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 curing temperature. Incidentally, the on / off control of the heater 50 may be set to operate when, for example, ± 3 ° C. is exceeded 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 it reaches 26 ° C., and the operation of the heater is started when it reaches 20 ° C.

  The “curing temperature control” step of ST6 will be specifically described from the flowchart of FIG. Further, the following description will be given by taking the 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, the number of stages “N” = “1” is first given.

  In ST60, the curing control device 6 first determines whether or not 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 is achieved (YES), the curing control device 6 determines whether it is within the curing period of the first stage A in ST62. This can be confirmed by calendar information etc. possessed by 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 one 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 apparatus 6 determines whether the stage number “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”, which is not the final stage (NO). Then, the curing control device 6 gives “N = N + 1” as the number of stages, and then repeats the second-stage curing temperature control step in ST60 to ST62. Steps after the second stage have been described above and will not be described in particular. However, in the case of the second stage B in FIG. Curing control is made so that

  In ST63, when N is the final stage (three stages C in the case of FIG. 3) (YES), the curing control device 6 achieves the curing period and curing temperature set in the final stage (three stages C). Control to do so. At that 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 last day of the curing period (18th day), the curing temperature (18 ° C.) of the previous stage (2 stages B) gradually approaches the outside air temperature (13 ° C.). Control is performed to lower the curing temperature. That is, the curing control device 6 acquires the measurement information acquired from the temperature measuring device 42 that measures the temperature of the outside air temperature and the measurement information acquired from the temperature measuring device 43 that measures the temperature of the concrete, and the temperature of the concrete. Is transmitted to the temperature control unit 5 in such a manner that the temperature is gradually lowered to approach the outside air temperature.

  Controlling to approach the outside air temperature means that the curing temperature is lowered so that the difference between the temperature of the concrete structure 2 and the outside air temperature falls within the control 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 or not the last curing period needs to be extended in ST65, and the extension is performed. When it is necessary to do this, the curing management schedule is changed (reset) by the analysis unit 61. In particular, the curing period of the final stage (3 stages C) is corrected, and the curing temperature drop schedule is changed accordingly. This is a step for dealing with a case in which, for example, when the outside air temperature is unexpected, the temperature difference from the concrete structure 2 is considerably widened, and the set curing temperature and curing period are difficult. Therefore, the curing control device 6 determines a necessary curing period using information on the difference between the temperature of the concrete structure 2 and the outside air temperature.

After the step ST65, based on the measurement information from the measurement management unit 4 and the curing management schedule (including the changed curing management schedule) in ST66, the control signal (ON) of the heater 50 is sent to the temperature control unit 5. Send off) to control the curing temperature in the final stage.
ST66 is set by finely dividing the curing control of ST61, and conceptually performs the curing control similar to 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 whether it is within the curing period of the final stage (three stages) in ST67. In the case of FIG. 3, the last stage curing period is 18 days (eyes). Moreover, in ST65, when the curing management schedule is changed, it is determined whether or not it is within the changed curing period.

  In ST67, when it is within the last curing period (YES), the process returns to ST64 and waits until the curing period is over while controlling the difference from the outside air temperature to be within the management value. In ST67, when the last curing period has passed (NO), the “curing temperature control” step is completed. 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 is terminated.

  Incidentally, after the concrete placement in ST4, when the measurement information acquired from the measurement management unit 4 exceeds the specified value, the curing control device 6 sends warning information to another terminal held by the administrator 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 an unspecified value. It is.

  Incidentally, the room temperature, the outside air temperature, and the temperature of the concrete structure 2 can be detected from the temperature information from the indoor temperature measuring device 41, the outdoor temperature measuring device 42, and the concrete temperature measuring device 43. Therefore, the difference between the temperatures may be calculated, and the warning information may be transmitted even when the difference exceeds a specified value. For example, if there is too much difference between the room temperature and the temperature of the concrete structure 2, it is necessary to deal with it immediately due to a problem of the curing enclosure or a failure of the temperature measuring instrument. 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 the three-dimensional finite element method analysis. That is, since a plurality of curing temperatures and curing periods based on the respective curing temperatures are set and the curing management schedule in which the curing temperature is lowered in stages is calculated, the conventional curing period is, for example, 10% to 15%. % Can be shortened.

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

  In the curing management schedule by the concrete curing control system of the present embodiment, at the final stage of the final stage, the concrete temperature is controlled to gradually decrease so as to approach the outside air temperature. Furthermore, it was set as the structure which completes curing, after confirming whether the difference of external temperature and the temperature of the concrete structure 2 was less than a management value. Therefore, it is possible to reliably prevent cracking and contribute to the construction of a high-quality concrete structure 2.

Further, the outer peripheral surface of the concrete structure 2 to be cured is sprinkled or humidified, and the outer peripheral surface after the water sprinkling or humidification is covered with a plastic film material 20 so as to be in a sealed state. An environment where watering and sealing are used together is prepared. Therefore, it is possible to prevent the surface of the concrete structure from cracking due to drying. In addition, it is not necessary to install a humidifier or a device or system for controlling the device, so it is desired to prevent a large-scale system and reduce costs and increase the efficiency of equipment installation work. Can do.
