Description

  The present invention relates to a concrete stacking time interval management system.

  Conventionally, in concrete work, the time interval for stacking concrete is a very important management item, and neglecting proper management leads to the occurrence of initial defects such as cold joints, making it impossible to ensure a predetermined concrete quality. For this reason, for example, in the Japan Society of Civil Engineers, the allowable stacking is performed so that the concrete is stacked for 2.0 hours when the environmental temperature exceeds 25 ° C and 2.5 hours when the environmental temperature is 25 ° C or less. A time interval standard value is defined (for example, see Non-Patent Document 1, Non-Patent Document 2, and Non-Patent Document 3).

Senjida Hamada: Properties of cold joints using ready-mixed concrete, Journal of Architectural Institute of Japan, No. 135, pp. 10-19, May 1967 Japan Society of Civil Engineers: Established in 2007 Standard Specification for Concrete [Construction], pp. 118-121, March 2008 Architectural Institute of Japan: JASS5 (2009 edition), pp. 262-264, February 2009

  On the other hand, there are many cases where it is difficult to manage the stacking time interval in detail because there are a plurality of stacked portions in the concrete placement work on site. At the site, for example, a management method is often used in which a signboard is posted, the allowable stacking time is specified on the signboard every time concrete is placed, and the concrete stacking time is made known to workers and the like. However, in such a management method using a signboard, it takes time and labor to produce and post a signboard, and there is a risk of human error such as a description mistake.

  In view of the above circumstances, an object of the present invention is to provide a concrete overlay time interval management system that enables more appropriate management of concrete overlay time intervals.

  In order to achieve the above object, the present invention provides the following means.

The concrete stacking time interval management system of the present invention is a concrete stacking time interval management system for managing the stacking time of concrete when performing concrete work, and is disposed above the formwork. For each time interval set in advance, a shape sensor that captures the shape of concrete placed in a part where the concrete placement range in the mold is difficult to see by the mold, and the shape data of the concrete sent from the shape sensor Based on this, the image processing / calculation device for obtaining the concrete placement area and the overlay line corresponding to the overlay surface, and the placement area and the overlay line for each time interval obtained by the image processing / calculation apparatus are displayed. And a display device that issues a warning when the elapsed time from the occurrence of the overlay line reaches a preset warning time. It is characterized in that is.

The concrete overlay time interval management system of the present invention is a concrete overlay time interval management system for managing the concrete overlay time when performing concrete work, and is disposed above the formwork. At a predetermined time interval, a shape sensor that captures the shape of the concrete placed in the mold, a concrete placement area based on the concrete shape data sent from the shape sensor, and the overlay An image processing / arithmetic device for determining a lap line corresponding to a surface, a driving area and a laying line for each time interval determined by the image processing / arithmetic device, and the generation of the lap line comprising a display device and for issuing a warning with time reaches the warning time set in advance, the image processing and computing apparatus, the lateral one direction inside the formwork A plurality of virtual reference points are set in advance in a distributed manner in a plan view, and a plurality of reference points at the position where the concrete placed in the mold has reached are connected, characterized in that it is configured to determine the punching overlapping line and the implanted region.

  In the concrete stacking time interval management system of the present invention, it is possible to automatically display, in real time, a stacking area corresponding to a stacking area and a stacking surface of each concrete to be placed in a mold multiple times. it can. In addition, the elapsed time from the occurrence of the overlay line, that is, the elapsed time from the placement of the concrete that has been exposed in the formwork and the surface is exposed reaches a preset warning time, and the overlay line is displayed. A warning can be automatically issued such as a color change, a warning display, or a warning sound.

  This makes it possible to appropriately manage the concrete stacking time interval by displaying the elapsed time of each stacking line. It is also possible to specify the amount of placement, the remaining amount of unplaced area, the amount of remaining concrete, the amount of return concrete, and the like based on the information of the concrete placement area and the overlay line.

  Furthermore, even if the concrete placement range, such as a beam, a column, or a wall, is difficult to see due to the formwork, the concrete placement area can be visualized almost in real time to confirm the concrete placement status.

  Therefore, according to the concrete stacking time interval management system of the present invention, the concrete stacking time interval can be managed more appropriately (accurately) and efficiently, and the risk of cold joint occurrence can be reduced. It is possible to improve the quality and productivity in planning and concrete work.
