Description

[Technical Field]

[0001] The present disclosure relates to a system for managing the curing of mortar or concrete. [Background technology]

[0002] Temperature has a significant impact on the strength development of concrete or mortar. To achieve rapid and efficient strength development, steam curing or autoclave curing is frequently performed at temperatures ranging from 40°C to a maximum of 200°C. Research has been conducted to efficiently perform these high-temperature curing processes, and the concrete curing system described in Patent Document 1 includes a heater (boiler), a temperature measuring device, a temperature control device, and a management device. The temperature measuring device transmits a concrete temperature measurement signal to the management device via a telephone line, and the management device transmits a control signal for controlling the temperature control device via a telephone line, thereby managing the concrete temperature.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-322470 Summary of the Invention [Problem to be solved by the invention]

[0004] The curing system described in Patent Document 1 is more than 20 years old and has become commonplace. While it does not include a heater, commercially available temperature control devices (temperature controllers) combine a temperature measurement device, temperature control device, and management device. Compact temperature controllers, such as the AS ONE TC-3000A digital temperature controller, are commercially available. These temperature controllers adjust the heater output depending on the rate at which the concrete temperature rises, controlling the curing temperature to maintain a predetermined temperature. However, on-site situations can arise in which the temperature controller itself breaks down due to an unexpected accident (e.g., exposure to rain or being hit), the temperature controller's power is unplugged by another contractor, or another contractor suddenly uses the distribution board, causing the power to exceed capacity, making it difficult to control the curing temperature.

[0005] When such an accident occurs, for example, the temperature of the concrete or mortar may become abnormally high or suddenly drop, resulting in a decline in the quality of the concrete or mortar. To deal with this, conventionally, heating curing contractors have had to stay on-site at all times during heating to monitor the heating status, which means they cannot leave the site. They must always be present at the location of the concrete being heated, and cannot even be present in the site office.

[0006] The objective of the present disclosure is to prevent the concrete or mortar from becoming abnormally hot or being insufficiently heated when the temperature controller or a part of it breaks down and it becomes impossible to control the curing temperature, thereby suppressing the deterioration of the quality of the concrete or mortar that would otherwise result, and also to reduce the labor of heating and curing contractors. [Means for solving the problem]

[0007] The curing management system of the first aspect is characterized by comprising a heater that heats mortar or concrete for the joint between a pair of concrete members, at least one of which is a precast concrete member; a detection unit that detects the temperature of the mortar or concrete; and a detection unit that detects an abnormality in the temperature of the mortar or concrete based on the detection result of the detection unit and stops operation of the heater.

[0008] According to the configuration of the first aspect, for example, if the control unit is unable to control the temperature, the detection unit detects an abnormality in the temperature of the mortar or concrete based on the detection result of the detection unit and stops the operation of the heater. In this way, even if it becomes impossible to control the curing temperature, it is possible to prevent the quality of the mortar or concrete from deteriorating due to the mortar or concrete reaching an abnormally high temperature.

[0009] The curing management system according to the second aspect is the curing management system according to the first aspect, characterized in that it has a function to notify the manager of an abnormality when an abnormality occurs, and a function to allow the status of the heater to be checked from outside, and that the detection unit stops operation of the heater when a threshold time has elapsed since the detection unit detected an abnormality in the temperature of the mortar or concrete.

[0010] According to the configuration of the second aspect, the detection unit notifies the site worker of the abnormality without stopping the heater operation immediately after detecting an abnormality in the temperature of the mortar or concrete. When a threshold time has elapsed since the detection unit detected the abnormality in the temperature of the mortar or concrete, the detection unit stops the heater operation. In other words, if the manager or site worker notices the alarm, checks the situation remotely, and resolves the abnormality within the threshold time, the heater operation continues. In this way, if the abnormality is resolved within the threshold time, the heater operation is not stopped, thereby preventing the temperature of the mortar or concrete from decreasing and preventing the construction period from being extended.

[0011] The curing management system according to the third aspect is characterized in that in the curing management system according to the first or second aspect, the control unit that keeps the temperature of the mortar or concrete within a threshold temperature is connected to a network and can be operated externally.

[0012] According to the configuration of the third aspect, if a manager is present in a remote location, the manager can adjust the heating method (heater output and heating time) from the remote location, and it becomes possible to prevent the heating from being stopped. If the abnormality is resolved within the threshold time, the heater operation is not stopped, thereby preventing the temperature of the mortar or concrete from decreasing and preventing the construction period from being extended.

[0013] The curing management system according to the fourth aspect is Any one of the first to third aspects In the curing management system described above, the detection unit detects at least the temperature of the central part and the temperature of the outer part of the mortar or concrete, and when the difference between the temperature of the central part and the temperature of the outer part of the mortar is equal to or greater than a threshold difference, the detection unit detects this as an abnormality in the temperature of the mortar.

[0014] According to the configuration of the fourth aspect, it is possible to prevent a difference in quality from occurring between the central portion and the outer portion of the mortar or concrete. [Effects of the Invention]

[0015] According to the present disclosure, even if the temperature controller or a part of it breaks down and it becomes impossible to control the curing temperature, it is possible to prevent the concrete or mortar from becoming abnormally hot or being insufficiently heated, thereby suppressing the deterioration of the quality of the concrete or mortar that would otherwise result. It is also possible to reduce the labor of the heating and curing contractor. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0017] A curing management system according to an embodiment of the present disclosure will be described with reference to FIGS. 1 to 3. FIG. (Cure Management System 100) As shown in Figure 1, the curing management system 100 (hereinafter simply referred to as "management system 100") manages the curing temperature of joint mortar 112 (hereinafter simply referred to as "mortar 112") at the joints (connections) of a pair of pillar members 110, which are precast concrete members. The pillar members 110 are an example of a concrete member. The management system 100 of the present invention can be used not only for joints but also for steam curing of individual concrete members on-site.

[0018] The management system 100 includes equipment that is placed at the site where the column members 110 are joined (where the concrete is heated), equipment that is placed in a remote location away from the site, and equipment that can be located either on site or in a remote location.

[0019] At the site, the management system 100 includes a thermocouple 18 (see FIG. 2), a heater 20, a temperature regulator 24, a switch 28, a temperature acquirer 32, a control computer 36, and an alarm 62. The management system 100 also includes a detection management computer 56 at the local or remote location. Furthermore, at the remote location, the management system 100 also includes a remote control computer 150, a smartphone 130, and an alarm 62. The management system 100 also includes a WIFI adapter 40 that wirelessly connects various locations. The manager will set up the heating equipment and handle any problems on-site, but will work in a remote location while the equipment is being heated.

[0020] [Thermocouple 18, Heater 20] The thermocouples 18 are components that detect the temperature of the mortar 112, and a plurality of thermocouples 18 are provided as shown in Fig. 2. The thermocouples 18 are arranged in a portion facing the mortar 112 from the outside and in a central portion of the mortar 112. The thermocouples 18 are an example of a detection unit. The heater 20 is a member that heats the mortar 112, and a rubber heater that is a planar heating element is used for the heater 20. As shown in Fig. 1, the heater 20 is attached to the side of the pillar members 110 at the portion where the pair of pillar members 110 face each other so as to cover the mortar 112 from the side of the pillar members 110. Furthermore, a heat insulating member (not shown) that covers the heater 20 from the outside is provided.

[0021] In this configuration, when power is supplied to the heater 20, the temperature of the heater 20 increases, and the heater 20 heats the mortar 112.

[0022] In this embodiment, a rubber heater is used as the heater 20, but it is sufficient to heat the mortar 112, and the mortar 112 may be heated by placing a heating wire such as an electric heating wire inside the mortar 112. The thermocouple 18 disposed in the portion facing the mortar 112 from the outside may be attached to the heater 20. Furthermore, the heater may be a boiler type heater used for steam curing.

[0023] [Temperature controller 24] The temperature regulator 24 is a component that controls the temperature of the heater 20 and is connected to the heater 20. The temperature regulator 24 receives a program for controlling the temperature of the heater 20 from a control computer 36 and controls the temperature of the heater 20. Temperature control software 36a is installed in the control computer 36. The temperature regulator 24 is an example of a control unit.

[0024] In this configuration, the temperature regulator 24 increases, maintains, or decreases the temperature of the heater 20 based on temperature data of the heater 20 received from a thermocouple 18 arranged outside facing the mortar 112 and a heating program for temperature control. The temperature regulator 24 then keeps the temperature of the mortar 112 within a threshold value.

[0025] [Switch 28] The switch 28 is a member that can stop or continue the supply of power to the temperature regulator 24 .

[0026] In this configuration, the switch 28 stops the supply of power to the temperature regulator 24 in response to an instruction from the detection management computer 56. This stops the heater 20 from heating the mortar 112. If the power supply to the heater does not go through the temperature regulator, the power supply to the heater is stopped directly.

[0027] [Control PC 36, temperature control software 36a] The control computer 36 is connected to the temperature regulator 24. Temperature control software 36a for controlling the temperature of the mortar 112 is installed in the control computer 36.

[0028] [Detection management computer 56, temperature monitoring software 56a] The detection management PC 56 is connected to the temperature acquirer 32 and also to the temperature controller 24 via the switch 28. Temperature monitoring software 56a that monitors the temperatures of the heater 20 and mortar 112 is installed in the detection management PC 56. The detection management PC 56 is also connected to an alarm 62 via a wired or wireless connection, and is further connected to a smartphone 130 via a wired or wireless connection, and has the function of sending emails to the smartphone 130 and sounding an incoming call. The detection management PC 56 is also connected to a network, and has the function of allowing the monitoring software to be viewed from a remote control PC or smartphone, which will be described later. The detection management PC 56 and temperature monitoring software 56a are examples of a detection unit.

[0029] The detection management computer 56 can be omitted if the temperature monitoring software 56a is installed in the control computer 36 or the remote control computer 150 described later. However, if it also serves as the control computer 36, the control computer 36 must have a battery-powered power source. In addition, in order to maintain the monitoring function, if the control computer 36 or the remote control computer 150 described later is used as the detection management computer 56, it must be kept running continuously.

[0030] In this configuration, the control computer 36 instructs the temperature controller 24 to heat the mortar 112, and the temperature controller 24 heats the mortar 112. Furthermore, the detection management computer 56 receives temperature data of the mortar 112 detected by the thermocouple 18 from the temperature acquirer 32, and monitors the temperature of the mortar 112. The specific configuration of the detection management computer 56 will be described below together with its operation.

[0031] [Temperature acquisition device 32] The temperature acquisition device 32 is a component that records the temperature data of the heater 20 and the internal temperature of the mortar at predetermined intervals, and is connected to thermocouples 18 (see Figure 2) placed in the part facing the mortar 112 from the outside and in the center of the mortar 112.

[0032] In this configuration, the temperature acquirer 32 uploads the temperature data detected by each thermocouple 18 to an online server (hereinafter sometimes simply referred to as the "server") at predetermined intervals. Furthermore, the temperature data uploaded by the temperature acquirer 32 is monitored by a detection management computer 56, which has installed therein temperature monitoring software 56a with a web scrolling function. As mentioned above, if the temperature monitoring software 56a is installed in the on-site control computer 36, the control computer 36 monitors the data. While the above example shows an example of uploading from the temperature acquirer 32 to the temperature monitoring software 56a, data can also be sent directly to the temperature monitoring software 56a. Using an online server increases the number of online recording media, and has the advantage of allowing the temperature to be checked even if the monitoring software fails.

[0033] [Remote Control PC 150] The remote control computer 150 is located at a remote location away from the site, and is capable of communicating with the detection management computer 56 and the control computer at the site via online communication.

[0034] In this configuration, the control computer 36 remotely checks the on-site conditions from the detection management computer 56 and the temperature monitoring software 56a, and operates the control computer 36 remotely in the event of an abnormality.

[0035] [Alarm 62] The alarm devices 62 are components that issue alarms by flashing and sounding an alarm, and are placed on-site and at remote locations away from the site, and each is connected to the detection management computer 56. Temperature monitoring software 56a is installed in the control computer 36 or the remote control computer 150. If the detection management computer 56 is omitted, the alarm devices 62 are connected to the control computer 36 or the remote control computer 150. In this configuration, when the temperature monitoring software 56a detects an abnormality in the temperature data uploaded to the server, the alarm 62 notifies the surrounding area of ​​the abnormality by flashing and sounding an alarm.

[0036] (action) Next, the operation of the management system 100 will be described with reference to the flow chart shown in FIG. For example, if the temperature regulator 24 becomes unable to control the temperature of the mortar 112, the temperature monitoring software 56a detects the abnormality from the temperature data uploaded to the server by the temperature acquirer 32. Then, in step S100, the temperature monitoring software 56a issues a notification that an abnormal situation has occurred.

[0037] For example, if the temperature of the heated mortar 112 deviates from the threshold, if the temperature data is not uploaded to the server by the temperature acquirer 32 within a specified time, if the power to the control computer 36 or the temperature regulator 24 is cut off, or if the difference in temperature between the central part and the outer part of the mortar 112 exceeds the threshold difference, the temperature monitoring software 56a will send a signal to indicate the occurrence of an abnormality.

[0038] Specifically, the temperature monitoring software 56a activates the alarm 62 and notifies the surrounding area of ​​the occurrence of an abnormal situation by flashing, sounding an alarm, or other warnings. Furthermore, the temperature monitoring software 56a sends emails to the administrator's smartphone 130 at predetermined intervals to notify the administrator that an abnormal situation has occurred. The temperature monitoring software 56a also continues to ring the smartphone 130. When the temperature monitoring software 56a notifies the administrator of the occurrence of an abnormal situation, the process proceeds to step S200.

[0039] In step S200, the temperature monitoring software 56a determines whether the administrator has canceled the alarm within a threshold time (e.g., within 30 minutes) after the abnormality notification was sent. If the administrator remotely checks the temperature monitoring software 56a and operates the temperature monitoring software 56a to cancel the alarm within the threshold time, the process proceeds to step S300. On the other hand, if the administrator does not cancel the alarm within the threshold time, the process proceeds to step S310.

[0040] In step S300, the administrator remotely checks the heating status by checking the temperature monitoring software 56a through online communication via the remote-control PC 150. After that, measures to deal with the abnormality are implemented by remotely controlling the control PC 36 or by performing on-site work.

[0041] For example, if the temperature of the heated mortar falls outside the threshold due to factors such as the outside air temperature or the shape of the construction site, the manager adjusts the temperature regulator 24 via the on-site control computer 36 using the remote-controlled computer 150.

[0042] If the insulating material covering the heater 20 or the heater 20 itself is wet, the manager will go to the site and carry out repair work on site. If the insulating material or the heater 20 is peeled off, the manager will go to the site and carry out repair work on site. If the wiring between each component is broken, the manager will go to the site and carry out repair work on site.

[0043] Furthermore, if the temperature data is not uploaded to the server within a predetermined time due to a malfunction of the temperature acquirer 32, the administrator goes to the site and replaces the temperature acquirer 32.

[0044] If the abnormal situation is resolved within the threshold time (for example, within 3 hours), the process proceeds to step S400. On the other hand, if the abnormal situation is not resolved within the threshold time (for example, within 3 hours), the process proceeds to step S410.

[0045] In step S400, the temperature monitoring software 56a controls the switch 28 to cause the heater 20 to continue heating the mortar.

[0046] On the other hand, if the administrator does not cancel the alarm within a threshold time (e.g., within 30 minutes) from the time the abnormality notification is issued in step S200, the process proceeds to step S310. In step S310, the temperature monitoring software 56a operates the switch 28 to stop the heater 20 from heating the mortar.

[0047] If the abnormality is not resolved within the threshold time in step S300, the process proceeds to step S410. In step S410, the temperature monitoring software 56a operates the switch 28 to stop heating the mortar by the heater 20. The threshold time set in this case is the time beyond which the mortar temperature may become abnormally high, possibly resulting in a deterioration in the quality of the mortar.

[0048] (summary) As described above, in the management system 100, the workplace of the manager is not on-site but in a remote location. This eliminates the need for the manager to be on-site all the time, resulting in manpower savings.

[0049] Furthermore, in the management system 100, in steps S310 and S410, heating of the mortar by the heater 20 is stopped. This makes it possible to prevent the quality of the mortar from deteriorating due to the mortar reaching an abnormally high temperature, even if it becomes impossible to control the curing temperature.

[0050] Furthermore, in the management system 100, if the abnormal situation is resolved within the threshold time and the process proceeds to step S400, the heating of the mortar by the heater 20 continues. In other words, the temperature monitoring software 56a stops heating of the mortar by the heater 20 when the threshold time has elapsed since the temperature monitoring software 56a detected the abnormal situation. In this way, if the abnormal situation is resolved within the threshold time, by not stopping heating of the mortar by the heater 20, it is possible to suppress a drop in the temperature of the mortar and prevent the construction period from becoming longer.

[0051] In addition, in the management system 100, when the difference in temperature between the center and outer parts of the mortar exceeds a threshold, the control computer 36 and the detection management computer 56 detect an abnormality. This makes it possible to prevent quality differences from occurring between the center and outer parts of the mortar.

[0052] While the present disclosure has been described in detail with respect to a specific embodiment, it will be apparent to those skilled in the art that the present disclosure is not limited to such an embodiment and that various other embodiments are possible within the scope of the present disclosure. For example, in the above embodiment, the mortar 112 connects a pair of precast concrete column members 110, but it is sufficient if at least one of the members is made of precast concrete. Furthermore, the mortar 112 can also be used on a single concrete member, such as when steam curing a concrete member.

[0053] Furthermore, in the above embodiment, online communication is enabled using WIFI, but other online communication may be used, or wired communication may also be used.

[0054] Although not specifically described in the above embodiment, if an abnormality is detected due to a decrease in the remaining battery charge of the temperature acquirer 32, the abnormality can be resolved by replacing the battery. The temperature acquirer does not have to be battery-powered.

[0055] Also, although not specifically described in the above embodiment, the smartphone 130 may be a mobile phone or a personal computer, and the personal computer may be a smartphone.

[0056] Although not specifically described in the above embodiment, the detection management computer 56 may have a function of issuing an alert by e-mail, telephone, or flashing a light.

[0057] Furthermore, in the above embodiment, the curing management system 100 is used for curing mortar, but it may also be used for curing concrete. [Explanation of symbols]
