Description

  The present invention relates to a quality information management system for a concrete structure.

In construction using concrete, various management such as process management, quality management, safety management, and labor management are performed. In particular, strict management has recently been required for the quality of concrete, which is one of the performance indicators of structures. At the construction site, the construction company's on-site staff conducts preparations for concrete placement while directing a specialized contractor, and performs work such as concrete placement, curing, mold removal, various measurements from the formwork and rebar assembly, In addition, at the key points, the orderer also receives inspections.
The quality of the concrete structure depends on whether such work is performed as specified, whether the concrete to be placed is correctly manufactured with a composition that expresses the strength as designed, and is supplied to the site. It's no exaggeration to say that it is determined by three main points: whether or not it is carefully cured after placement.

Therefore, when the orderer or future user asks about the quality of the concrete structure after construction, it is necessary to fulfill accountability for the above three points. For this reason, it is important to leave a construction history in the form of documents including orderer inspection forms and quality test sheets. These construction histories have been managed and stored as output information on paper.
However, when such information is spelled out in a file as a completed book and stored in the warehouse, it becomes a material that is completely unknown to engineers other than those involved in the construction and is buried. It was in the situation.

  In order to prevent the burial of construction history and improve the traceability of quality information, it is considered to digitize paper information by means of a scanner or manual input. In this case as well, the digitized quality information is stored in the data server. The concern of being buried in a so-called electronic warehouse is unavoidable. In order to prevent such information from being buried, it is considered to use a three-dimensional CAD, a form management technique, and an information retrieval technique.

However, three-dimensional CAD has a mechanism that has drawing attributes such as color and line type corresponding to each drawing component, but it is a detailed member of a three-dimensionally expressed structure. On the other hand, there is a problem that there is no mechanism for providing work information and quality information.
In addition, the form management technology has a problem that there is no mechanism for systematically managing work information and quality information using a three-dimensional model in which construction sites are subdivided as an index.
Furthermore, there are many techniques for searching and extracting necessary information from work information and quality information stored in the database, but the search results are mainly expressed in tabular form, and the position of the information is visually determined. Has the disadvantage that it cannot be recognized.

  In view of the current situation as described above, an object of the present invention is to provide a system that can quickly search for information related to the quality of concrete and provide the information so that anyone can easily see it. is there.

Here, the graphic data of the concrete structure includes a design drawing, and examples thereof include CAD data in which two-dimensional or three-dimensional vector data is stored in a predetermined file format such as a Data exchange file.
Create a 2D model or 3D model of a concrete frame from such graphic data, and subdivide the 2D model or 3D model so that the range that can be placed by a single concrete placing process is the smallest unit. Means to create information units, to register various data obtained in the process of designing, constructing and maintaining concrete frames in the concrete data storage means, and to link the information unit storage means and the concrete data storage means Means for retrieving predetermined concrete data, and means for generating and outputting information retrieved by the information retrieval means as an image together with the information unit uses one or a plurality of computer software. For example, using general-purpose CAD software, CAD data can be Three-dimensionally or subdivided, it is possible to use a function, such as the GUI that is incorporated in a general-purpose software tool (graphic user interface), which frequently used in program development.
Examples of means for storing the information unit include a computer hard desk and a data server.

  The range that can be placed by the single concrete placing process is a range in which concrete is placed once in a continuous manner without being interrupted due to external factors such as changes in weather such as rain or sunset. Therefore, it means a range in which information on quality etc. is formed by the same concrete.

The various data obtained in the process of designing, constructing and maintaining the concrete frame is information such as the following types, and the following types are further composed of information of the following items, and these data are registered for each information unit. Is done. In addition, the maintenance management of the concrete frame includes the management from the concrete curing to the maintenance and maintenance of the concrete structure in use after the concrete is hardened after the concrete frame is constructed.
