Description

  The present invention is a concrete overlaying time suitable for managing the stacking time in order to prevent the occurrence of cold joints in concrete construction work such as large-scale underground structures such as water purification plants and subway stations. The present invention relates to a management notification device and a concrete overlaying time management method using this device.

  Conventionally, when constructing a concrete structure such as a large underground structure such as a water purification plant or a subway station, for example, in the concrete placement on the same day, the structure is constructed by stacking concrete in multiple layers (for example, , See Patent Document 1). When placing new concrete on concrete that has been set, if the concrete is placed after an appropriate time interval, the concrete that has begun to harden and the concrete that has been piled later will not be integrated, Cold joints that produce discontinuous surfaces may occur.

  Since a cold joint becomes a structural weak part, in order to prevent generation | occurrence | production, it is necessary to drive | pour so that the stacking time interval for every layer may be set to the time interval which does not generate | occur | produce a cold joint. An appropriate stacking time interval until stacking of concrete is often planned as, for example, 2 hours under construction conditions with a temperature of 25 ° C. or less, and 2 hours 30 minutes under construction conditions with a temperature exceeding 25 ° C. (for example, (Refer nonpatent literature 1). Therefore, there is a high possibility that a cold joint will occur when the time interval is exceeded.

  On the other hand, for example, a technique of Patent Document 2 is known as a construction management technique for a concrete structure constructed by a plurality of times of concrete joining. In this Patent Document 2, in order to investigate the cause of a problem when a problem occurs in a part of a concrete structure constructed by multiple times of concrete joining, the construction information of the part where the problem has occurred, History information (traceability) such as manufacturing information of used concrete and test result information for quality confirmation is easily grasped.

  DESCRIPTION OF EMBODIMENTS Embodiments of a concrete overlay time management notification device and a concrete overlay time management method according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

  As shown in FIG. 1, a concrete overlaying time management notification device 10 according to the present invention is a device for notifying information related to concrete overlaying time management, and displays the remaining time of a predetermined overlaying time. And a notification information display means 14 for displaying notification information corresponding to the remaining time of the overlapping time. The concrete overlaying time management notifying device 10 further includes an operation start means 16 including a push button for operating the time display means 12 and the notification information display means 14.

  The time display means 12 is a horizontally long flat plate-shaped object composed of a 7-segment LED display, and digitally displays the remaining overlapping time as a number in a countdown manner from a predetermined overlapping time. This makes it easier to visually recognize the remaining time of the overlapping time.

  In the example of FIG. 1, “02:30” is displayed on the LED display, indicating that the remaining stacking time is 2 hours 30 minutes. For this reason, if the person who exists in a concrete placement site looks at the time display means 12, he can grasp | ascertain reliably and easily the remaining time of stacking time. Therefore, as the mode of the numbers digitally displayed on the LED display, the size, color, and brightness that can be easily read by those who are at the concrete placement site (for example, workers who are several tens of meters away). It is preferable.

  1 and the like show the case where the background color of the LED display is white and the LED lighting part is black for the sake of convenience, but the present invention is not limited to this. For example, the background color is black to improve the visibility. In addition, the LED lighting portion may be a warm color such as red, orange or yellow, and a combination of other colors may be used. Moreover, in order to improve visibility and convenience, you may employ | adopt the combination of the color suitable for construction time zones, such as nighttime and daytime.

  The notification information display means 14 is provided close to the right side of the time display means 12 and is formed in a vertically long rectangular parallelepiped shape higher than the height of the time display means 12 in order to improve visibility. The notification information display means 14 includes a rotating lamp 14a in which light emitting portions 24a to 24c each having a light source capable of rotating a light emission direction about an axis in the vertical direction are stacked in three stages in order from the bottom. Provided on top. The side of each light emission part 24a-24c is each covered with transparent glass 28a-28c.

  The rotating lamp 14a can emit different colors outward from the light emitting sections 24a to 24c in all directions, and emit light of a predetermined color corresponding to predetermined notification information. It emits light corresponding to the remaining time of the stacking time from the light emitting part capable of emitting light. In the example of FIG. 1, the rotating lamp 14a is configured as a three-color rotating lamp capable of emitting three colors of blue, yellow, and red from each of the light emitting sections 24a, 24b, and 24c.

  Here, as a correspondence relationship between each color and the notification information, for example, notification information that the remaining time of the overlapping time is large in the case of blue, and notification information that the remaining time of the overlapping time is medium in the case of yellow. In the case of red, it is conceivable to show notification information that the remaining time of the overlapping time is short.

  Since the rotating lamp 14a gradually changes the color of the direction light from the light emitting part in order of blue, yellow and red as the remaining time of the stacking time decreases, the remaining stacking time is visualized. If a person around the revolving light 14a observes this, the remaining time of the overlapping time can be recognized more visually and intuitively. For example, if the predetermined overlap time is 2 hours and 30 minutes, the remaining time is blue for 2 hours 30 minutes to 1 hour, the remaining time is yellow for 1 hour to 30 minutes, and the remaining time is 30 minutes to 0 minutes. May be set to emit light from each light emitting unit in red or, of course, each may be set to a time width other than this.

  The operation start means 16 is constituted by a push button for operating the time display means 12 and the notification information display means 14, and is provided at the top of the casing of the time display means 12 so as to be able to appear and disappear. For example, when the push button is pressed when the concrete one-layer placement is completed, the time display means 12 and the notification information display means 14 start operation, and the LED display of the time display means 12 has a predetermined overlay time. The remaining time is displayed, and light is emitted from the rotating light 14a of the notification information display means 14 from the light emitting portion of the color corresponding to the remaining time. Note that the remaining time displayed on the time display unit 12 decreases with the passage of time, and the color emitted from the rotating lamp 14 of the notification information display unit 14 according to the decrease in the remaining time is, for example, blue or yellow It will change in red and step by step.

  Next, the block configuration of the concrete overlay time management notification device 10 of the present invention will be described.

As shown in FIG. 2, the concrete overlaying time management notification device 10 includes a time measuring means for measuring time in addition to the time display means 12, the notification information display means 14, and the operation start means 16 described above. 18, a stacking time setting unit 20 for setting a stacking time, and a control unit 22 having a CPU for controlling these units. The time measuring means 18 and the control means 22 are provided inside the casing of the time display means 12 or the base 26 of the notification information display means 14.

  The overlapping time setting means 20 is constituted by a numeric keypad for inputting numerical values, a push button or the like, and can be provided on the casing of the time display means 12 or the notification information display means 14. Also, instead of doing this, a wireless remote control or the like is provided with a numeric keypad or push button, and a remote control receiving means is provided on the casing side of the time display means 12 or the notification information display means 14 so that the overlap time can be set by a remote operation. It is good.

  In the above configuration, when the overlay time is set through the overlay time setting means 20 by the operator, the control means 22 waits for an input from the operation start means 16. When the push button of the operation start means 16 is pressed by the operator, the control means 22 calculates the remaining time of the overlapping time by the countdown method from the set overlapping time based on the time measured by the time measuring means 18. The calculated remaining time is displayed on the time display means 12 in real time. On the other hand, the control unit 22 performs a process of displaying predetermined notification information on the notification information display unit 14 in conjunction with the calculated remaining time. By such processing, the remaining time and the notification information can be displayed on the time display unit 12 and the notification information display unit 14.

In addition, the remaining time of the stacking time can be shared.

  In particular, if the time display means 12 is visually checked, the remaining time of the overlaying time can be grasped, and at the same time, the rotating light of the notification information display means 14 provided in the vicinity is colored in blue, yellow or red. Since the light immediately enters the eye, it is possible to more intuitively grasp the remaining time of the stacking time. In addition, according to the present invention, since all workers can easily confirm the remaining stacking time by visual observation, the management of the stacking time is prevented from becoming ambiguous, and the management of the stacking time is compared with the conventional method. Can be more reliable. For this reason, the on-site supervisor forgets the record of the completion time of placement and there is no fear of construction failure due to incorrect recording.

  Next, display examples by the concrete overlay time management notification device 10 of the present invention will be described with reference to FIGS. In the following example, a case where a predetermined overlapping time is 2 hours 30 minutes will be described. Further, the remaining time of the stacking time is emitted in blue from 2 hours 30 minutes to 1 hour, yellow in the remaining time from 1 hour to 30 minutes, and red in the remaining time from 30 minutes to 0 minutes.

I'm leaning. Therefore, it can be seen that the remaining time of the stacking time is 1 hour 30 minutes, and the remaining time is still sufficiently long.

  As shown in FIG. 5, “00:45” representing the remaining time is displayed on the time display unit 12, and yellow light is emitted from the rotating lamp 14 a of the notification information display unit 14 by the middle light emitting unit 24 b. ing. Therefore, it can be seen that the remaining time of the stacking time is 45 minutes and the remaining time is moderate but not sufficient.

  As shown in FIG. 6, “00:10” representing the remaining time is displayed on the time display unit 12, and red light is emitted from the rotating lamp 14 a of the notification information display unit 14 by the uppermost light emitting unit 24 c. I'm leaning. Therefore, it can be seen that the remaining time of the stacking time is 10 minutes and there is almost no remaining time.

  In the above embodiment, the case where the notification information display means 14 is configured by three-color rotating lamps that are stacked in three stages in the vertical direction has been described. However, the configuration is appropriately changed according to construction conditions, site conditions, and the like. May be. For example, the number of rotating lamps is not limited to three, but may be configured by stacking a plurality of stages of one stage, two stages, four stages or more to realize a multi-color rotating lamp. Further, instead of stacking a plurality of stages in the vertical direction, a rotating lamp may be realized by stacking a plurality of stages in the left-right direction or the front-rear direction. Further, a simple illumination lamp may be used instead of a rotating lamp, or a blinking lamp that simply blinks light may be used.

  Further, in the above embodiment, the case where the notification information display unit 14 is provided close to the right side of the time display unit 12 has been described. However, the present invention is not limited to this, and is close to the left side of the time display unit 12. It may be arranged close to the upper part or the lower part, and the notification information display means 14 may be arranged away from the time display means 12. In any case, it is desirable to arrange the time display means 12 and the notification information display means 14 at positions where they can be surely and easily viewed from a person at the concrete placement site. Further, the notification information display unit 14 may be integrated with the casing of the time display unit 12 or may be incorporated into the LED display of the time display unit 12.
