Description

  The present invention relates to a concrete quality control method for centrally performing quality control of a concrete structure and maintenance management after construction.

  Conventionally, in order to manage the quality of concrete in construction work of concrete structures such as bridges, dams, tunnels, roads, etc., the JIS standards, etc. are based on the materials submitted by the construction contractor. This is done by confirming that the standard values of the product are satisfied, and that the specifications described in the civil works common specifications are applied at the time of construction. There were problems such as delays in construction and deterioration of concrete quality due to the burden of document preparation. In addition, it has been difficult to maintain and manage a vast amount of data created for each construction and to use it for subsequent construction and maintenance.

  In recent years, in order to solve the above-mentioned problems, some have been proposed for the purpose of quality control of concrete. For example, in Patent Document 1 below, a moisture measuring device such as ready-mixed concrete, mortar, and sand used in the field is connected to a central management device having data processing and data communication functions through a communication line, and measured by the moisture measuring device in the field. Quality control that centrally manages the quality of ready-mixed concrete, mortar, sand, etc. by sending the test object data to a central management device via a communication line and returning the quality pass / fail judgment result based on that data A method is described.

In the following Patent Document 2, a producer computer installed on a producer side that manufactures concrete, and a purchaser who purchases the concrete produced by the producer connected to the producer computer via a predetermined network. A purchaser-side computer installed on the production side, the producer-side computer is provided with an input means for inputting concrete production information, and a quality control database for storing the production information is provided in the production A concrete quality control system provided on a purchaser computer or the purchaser computer and provided with display means for displaying the manufacturing information is described in the purchaser computer.

At this time, the distribution method of the quality record registration support tool or the like is based on a method in which the supervisor computer 4 transmits to the contractor computer 7 through the communication line 5 or an electronic medium (magnetic disk, optical disk, magneto-optical disk, Either the method of sending the electronic medium after recording it on a removable recording medium (medium) that can be removed from the drive device such as a memory card, or the method of sending the latter, but sending the latter electronic medium The method is preferable in terms of data handling and safety.

[During construction period]
(Quality control data creation procedure)
Next, the quality control data creation procedure performed during the construction period will be described. During the construction period, the contractor 6 inputs the concrete quality data into the predetermined quality control table registered in the quality record registration support tool for each concrete construction work. Then, the data is transmitted to the supervisor side computer 4 and the supervisor 3 confirms the quality record registration support tool.

  As shown in FIG. 3 to FIG. 6, the quality control data creation procedure was established depending on whether the concrete structure to be constructed is a target structure or a non-target structure whose quality record is to be preserved. It depends on whether the concrete is ready-mixed concrete or a secondary concrete product.

A converted frequency diagram and a frequency table that is a numerical value table thereof are automatically created and input to predetermined locations of the frequency table. In addition, based on the mortar and concrete compressive strength tests obtained in step 102 and the unit water amount test of concrete obtained in step 106, the test values such as the date on the horizontal axis and the slump and air volume on the vertical axis are graphed. The process capability chart is automatically created. In the same way as the X-Rs-Rm control chart in step 104, the supervisor 3 uses the frequency chart, frequency table, and process capability chart as a guideline to check whether the quality of the concrete conforms to various standard values and standard values. Can be determined. In addition to the reference value and the standard value, in this quality control method, a set value can be registered so that an arbitrary value such as an in-house target value can be discriminated.

  The condition search is a search method based on each item of the construction information data input in the construction registration procedure or the concrete quality data input in the quality control data creation procedure.

  In the search method based on the construction information data, the search condition items are, for example, structure name, structure type, supervisor name, construction year, construction name, road station (road station, road distance marker, river Data such as station, river distance marker, prefecture name, construction site name, etc.). In the search method based on the concrete quality data, the items of the search conditions are aggregate production area, design standard strength, slump, concrete type (raw concrete manufacturing factory name, ready mixed concrete classification, nominal strength, concrete secondary product manufacturing factory. Name).

  A specific procedure for the condition search is as follows. The supervisor computer 4 executes the condition search program registered in the central processing computer 1 while connected to the central processing computer 1 through the communication line 2, and sets the predetermined items. Search by entering predetermined items. As a result, a list of construction works that match the predetermined items is displayed, and the final concrete quality control data, quality record drawings, and composition reports registered in the construction work can be viewed.

  The map search is a method of searching from a map on which structure icons are displayed. First, the supervisor 3 registers the position information of the structure in the supervisor computer 4 while being connected to the central processing computer 1 through the communication line 2. In this registration method, the position information registration program registered in the central processing computer 1 is executed to register the position information of the structure. The position information can be registered by inputting a longitude and latitude. If the longitude and latitude are unknown, the position information can be specified and registered on the map. The structure that has acquired the position information in this way is displayed as an icon on the map. Then, the supervisor 3 displays a map of a predetermined range in the supervisor computer 4 while being connected to the central processing computer 1 through the communication line 2 and clicks and selects the icon displayed on the map. Thus, the concrete quality control data of the structure can be searched.
