Description

The present invention relates to a construction management system for anchor frames used to secure the base plate of a column base to foundation concrete.

Conventionally, a column base anchor structure for fixing a column base to a concrete foundation is known (for example, Patent Document 1). The conventional column base anchor structure includes a base that is placed on the leveled concrete, and an anchor frame that is installed on the base. The anchor frame has a lower form plate that is directly attached to the base, anchor bolts that are fixed to the lower form plate, and an upper form plate. The anchor bolts are bolts for fixing a base plate that is joined to the column base to the concrete foundation. The upper form plate is a member for maintaining the pitch between the anchor bolts when the anchor frame is installed.

The specifications of the mounting base and anchor frame are determined in advance by standards, and are selected according to the type and size of the base plate. Furthermore, these components that make up the column base anchor structure are generally assembled at the construction site.

JP 2018-53563 A

Anchor frames with various specifications are delivered to construction sites. In addition, it may be possible to install anchor frames on the mounting base that have specifications that are slightly different from those specified at the time of design. As a result, there is a risk that an anchor frame with specifications different from those specified at the time of design will be mistakenly installed on the mounting base.

If an anchor frame with specifications different from those specified during design is attached to the mounting base, the positions of the anchor bolts on the anchor frame will not match the positions of the bolt holes formed in the base plate. As a result, the base plate cannot be fixed with the anchor bolts.

At the stage where the base plate is fixed with anchor bolts, the anchor frame is already embedded in the foundation concrete. Therefore, if an anchor frame with specifications different from those determined at the time of design is mistakenly installed on the mounting base, it will be necessary to chip away the foundation concrete and reinstall the column base anchor structure.

The present invention aims to provide an anchor frame construction management system that can reliably prevent an anchor frame with specifications different from those selected at the time of design from being installed on a mounting base.

One embodiment of the present invention will be described below with reference to the drawings. It goes without saying that the present invention is not limited to this embodiment.

Figures 1 to 3 show the column base anchor structure.

This embodiment relates to a construction management system for an anchor frame 3 for fixing a base plate 11 joined to the lower end of a column 1. The anchor frame 3 is installed on a base 2 to form a column base anchor structure, and is embedded in foundation concrete 4.

The stand 2 is a member that is placed on the leveled concrete 5 poured on the ground and supports the anchor frame 3. The stand 2 is selected and determined at the time of design from a variety of stand 2 specifications, depending on the shape and size of the base plate 11, etc.

The frame 2 is formed into a rectangular parallelepiped shape by joining steel materials such as steel beams. The frame 2 has pillars 21, cross members 22, supports 23, and a base 24. These members are manufactured in a factory, shipped to the construction site, and assembled at the construction site. Alternatively, these members may be preassembled at the factory and shipped to the construction site.

The pillars 21 are arranged at the four corners of the frame 2 in a plan view. The pillars 21 are also arranged perpendicular to the leveling concrete 5. Steel materials such as angle iron are used for the pillars 21.

The cross member 22 is installed between the upper ends of the two pillars 21 and connects the pillars 21 to each other. Steel materials such as angle iron are used for the cross member 22.

The support parts 23 are parts that extend horizontally and away from the upper ends of at least a pair of cross members 22 that are arranged opposite each other. The support parts 23 support the anchor frame 3 on their upper surfaces. The longitudinal length of the support parts 23 is set to a length that does not interfere with the anchor bolts 31 (described later) when the anchor frame 3 is installed on the stand 2.

In order to more stably support the anchor frame 3, the support parts 23 may protrude from the upper ends of all the cross members 22 as long as they do not interfere with the anchor bolts 31. In addition, if the cross members 22 are made of angle iron, the support parts 23 will be formed integrally with the cross members 22.

The base 24 is a member that connects the lower ends of the pillars 21 and ensures the stability of the stand 2.

The anchor frame 3 is a component that is installed on the mounting base 2. After the anchor frame 3 is installed on the mounting base 2, these components are embedded in the foundation concrete 4.

The anchor frame 3 has an anchor bolt 31, a lower plate 32, a nut 33, an upper plate 34, and a nut 35. These components are manufactured in a factory, shipped to the construction site, and assembled at the construction site.

The anchor bolt 31 is inserted into a bolt hole 12 formed at a predetermined position in the base plate 11 and, together with the nut 35, secures the base plate 11 to the foundation concrete 4.

The lower plate 32 is a frame-shaped iron plate that connects the lower ends of the anchor bolts 31. As shown in FIG. 3, the lower plate 32 has anchor bolt insertion holes 321 formed at predetermined positions. In addition, a rectangular through hole 322 is formed in the center of the lower plate 32. The anchor bolt insertion holes 321 are formed at positions corresponding to the bolt holes 12 drilled in the base plate 11.

The type of lower plate 32 with the optimum specifications is selected and determined at the time of design from among multiple types of lower plate 32 that differ in size and position of anchor bolt insertion hole 321, in accordance with the size of the base plate 11 and the position of the bolt hole 12. If the type of lower plate 32 is different, the specifications of the anchor frame 3 will be different. In other words, anchor frames 3 with different specifications will have lower plate 32 of different types, and if the type of lower plate 32 can be determined, the specifications of the anchor frame can be identified.

The anchor bolt 31 is inserted through the anchor bolt insertion hole 321 of the lower plate 32, and the anchor bolt 31 is fixed to the lower plate 32 by screwing the two nuts 33 onto the anchor bolt 31 while the lower plate 32 is sandwiched between them.

The lower plate 32 is placed on the support portion 23 of the stand 2 and joined to the stand 2 by welding or the like.

The upper plate 34 is a temporary fixing member that connects the upper ends of the anchor bolts 31 and maintains each anchor bolt 31 in a vertical state. The upper plate 34 has a structure similar to that of the lower plate 32. If the type of the lower plate 32 is different, the type of the upper plate 34 will be different accordingly, and the specifications of the anchor frame 3 will be different. In other words, anchor frames 3 with different specifications will have different types of upper plates 34, and if the type of the upper plate 34 can be determined, the specifications of the anchor frame 3 can be identified.

The base 2 is placed on the leveled concrete 5, the anchor frame 3 is installed on the base 2, and then the foundation concrete 4 is poured until it reaches a height slightly below the upper plate 34. Therefore, most of the base 2 and the anchor frame 3 are buried in the foundation concrete 4.

When the foundation concrete 4 hardens, the upper plate 34 is removed. Then, the anchor bolts 31 protruding upward from the surface of the foundation concrete 4 are inserted into the bolt holes 12 of the base plate 11, and the base plate 11 is placed on the foundation concrete 4. Finally, the nuts 35 are tightened onto the anchor bolts 31, thereby fixing the base plate 11 onto the foundation concrete 4.

Next, we will explain the construction management system for the anchor frame 3. The construction management system for the anchor frame 3 includes a tag information generation device operated in the manufacturing plant for the anchor frame 3 and a tag information output device operated at the construction site.

Figure 4 is a block diagram showing an example of the hardware configuration of the tag information generation device 6. The tag information generation device 6 includes an information acquisition device 61, a control device 62, a tag creation device 63, and an input device 64.

The information acquisition device 61 is a device that acquires information about the components (lower plate 32 in this embodiment) that constitute the anchor frame 3 manufactured in the manufacturing factory. The information acquisition device 61 is, for example, an imaging device such as a camera. When the information acquisition device 61 is an imaging device, the information acquisition device 61 acquires image information of the components that constitute the anchor frame 3. The information acquired by the information acquisition device 61 is output to the control device 62.

The control device 62 is a device that controls the tag information generating device 6. The control device 62 is, for example, a PC (Personal Computer). The control device 62 has a CPU (Central Processing Unit) 62a, a ROM (Read Only Memory) 62b, a RAM (Random Access Memory) 62c, and a non-volatile memory 62d.

The CPU 62a processes, for example, information input from the information acquisition device 61. The CPU 62a also controls the entire tag information generation device 6 based on the system program.

ROM 62b is, for example, a storage device that stores a system program for controlling the tag information generation device 6.

RAM 62c is a storage device that temporarily stores information. For example, RAM 62c stores information that is temporarily calculated when CPU 62a processes information acquired by information acquisition device 61.

The non-volatile memory 62d is, for example, a solid state drive (SSD). The non-volatile memory 62d stores, for example, information about the lower plate 32 acquired by the information acquisition device 61. Note that the control device 62 may store various information using an external storage device such as a cloud server in addition to or instead of the non-volatile memory 62d.

The tag creation device 63 is a device for embedding identification information in the tag 323 (see FIG. 3) that is attached to the lower plate 32 as a component of the anchor frame 3. If the tag 323 is an RF (Radio Frequency) tag, the tag creation device 63 is a writing device that writes information into the RF tag.

The input device 64 is a device that accepts information input to the tag information generation device 6. The input device 64 is, for example, a user interface such as a touch panel or a keyboard. The information input to the input device 64 is output to the control device 62.

Figure 5 is a block diagram showing an example of the hardware configuration of the tag information output device 7. The tag information output device 7 includes a tag reader 71, a management device 72, and a display device 73.

The tag reader 71 is a device that reads information embedded in the tag 323. If the tag 323 is an RF tag, the tag reader 71 is an RF tag reader.

The management device 72 is a device that stores or processes information read by the tag reader 71. The management device 72 is, for example, a PC or a mobile terminal such as a smartphone. The management device 72 has a CPU 72a, a ROM 72b, a RAM 72c, and a non-volatile memory 72d.

The CPU 72a processes, for example, the information read by the tag reader 71. The CPU 72a also controls the entire tag information output device 7 based on the system program.

ROM 72b is, for example, a storage device that stores the system program of the tag information output device 7.

RAM 72c is a storage device that temporarily stores information. For example, RAM 72c stores information that is temporarily calculated when CPU 72a processes information read by tag reader 71.

The non-volatile memory 72d is, for example, an SSD. The non-volatile memory 72d stores, for example, information read by the tag reader 71. Note that the management device 72 may store various types of information using an external storage device such as a cloud server in addition to or instead of the non-volatile memory 72d.

The display device 73 is a device that displays information processed by the management device 72. The display device 73 is, for example, a liquid crystal display of a PC or a display of a mobile terminal such as a smartphone.

Figure 6 is a block diagram showing an example of the functions of the tag information generation device 6.

The information acquisition device 61 has an information acquisition unit 611. The information acquisition unit 611 acquires information on the members constituting the anchor frame 3 (the lower plate 32 in this embodiment). The information on the members constituting the anchor frame 3 is, for example, image information on the lower plate 32. In other words, if the information acquisition device 61 is a camera, the information acquisition unit 611 acquires image information of the lower plate 32 captured by the camera and outputs it to the control device 62.

The control device 62 has a processing unit 621 and a memory unit 622.

The processing unit 621 analyzes the information of the lower plate 32 acquired by the information acquisition unit 611, and performs processing to identify the lower plate 32 indicated by the information. For example, the processing unit 621 compares the image information of the lower plate 32 acquired by the information acquisition unit 611 with image information of various types of lower plate 32 stored in the memory unit 622. Through this processing, the processing unit 621 identifies image information that matches the image information acquired by the information acquisition unit 611 from the image information of various types of lower plate 32 stored in the memory unit 622, and identifies identification information of the lower plate 32 indicated by the image information acquired by the information acquisition unit 611. The identification information is information that can identify the lower plate 32, and is, for example, information indicating the type of the lower plate 32.

The processing unit 621 identifies the lower plate 32 indicated by the image information acquired by the information acquisition unit 611, for example, by comparing the size of the lower plate 32 and the positions and number of anchor bolt insertion holes 321 indicated by the image information acquired by the information acquisition unit 611 with the sizes of the lower plate 32 and the positions and number of anchor bolt insertion holes 321 of various types of lower plate 32 indicated by the image information stored in the memory unit 622. The processing unit 621 outputs identification information capable of identifying the lower plate 32 to the tag creation device 63.

As described above, the memory unit 622 stores information on various types of lower plate 32. The information on the lower plate 32 stored in the memory unit 622 includes, for example, image information on the lower plate 32, the size of the lower plate 32, the positions and number of the anchor bolt insertion holes 321, and identification information that can identify the lower plate 32.

The tag creation device 63 has a tag information creation unit 631 and a writing unit 632.

The tag information creation unit 631 encodes the identification information of the lower plate 32 identified by the processing unit 621.

The writing unit 632 writes the identification information coded by the tag information creation unit 631 to the tag 323.

The input device 64 has an input section 641.

The input unit 641 accepts input operations of information relating to the construction site to which the anchor frame 3 (lower plate 32) is to be delivered from the user. The information relating to the construction site to which the anchor frame 3 (lower plate 32) is to be delivered input from the input unit 641 is sent to the tag creation device 63 via the control device 62.

The tag information creation unit 631 creates delivery destination information indicating the delivery destination by encoding information about the construction site of the delivery destination. The delivery destination information is, for example, the name of the structure to be constructed at the construction site to which the anchor frame 3 (lower form plate 32) is delivered, and the address of the construction site. The writing unit 632 writes the delivery destination information together with the above-mentioned identification information into the tag 323 attached to the member (lower form plate 32) that constitutes the anchor frame 3.

The tag 323 with the embedded identification information and delivery destination information is immediately attached to the surface of the lower plate 32, which is a component of the corresponding anchor frame 3. The lower plate 32 with the tag 323 attached is shipped to the construction site of the delivery destination. The model number is written separately on the surface of the lower plate 32 with chalk or the like.

Figure 7 is a block diagram illustrating an example of the function of the tag information output device 7.

The tag reader 71 has a reading unit 711.

The reading unit 711 reads the information embedded in the tag 323. That is, the reading unit 711 reads the identification information and delivery destination information embedded in the tag 323 at the manufacturing plant of the anchor frame 3. The reading unit 711 outputs the read information to the management device 72.

The management device 72 has a location information acquisition unit 721, a placement information creation unit 722, an output unit 723, a design information storage unit 724, a receiving site information storage unit 725, a determination unit 726, an identification information storage unit 727, a calculation unit 728, and a receiving information storage unit 729.

The position information acquisition unit 721 acquires the position of the tag reading device 71 when the reading unit 711 reads the identification information embedded in the tag 323 of the lower plate 32 as the position of the anchor frame 3.

The position information acquisition unit 721 acquires the position information of the lower plate 32 as the position of the anchor frame 3, for example, using a GPS (Global Positioning System). For example, the tag reading device 71 includes a GPS receiver (not shown), and the position information acquisition unit 721 acquires the position of the GPS receiver when the reading unit 711 reads the identification information from the tag 323 of the lower plate 32 as the position of the anchor frame 3. In other words, when the reading unit 711 reads the identification information embedded in the tag 323 with the anchor frame 3 placed on the stand 2 at the construction site, the tag reading device 71 is placed in a position in contact with or close to the tag 323, so that the position of the GPS receiver included in the tag reading device 71 can be considered as the position of the lower plate 32, i.e., the anchor frame 3. The position information of the tag 323 includes, for example, information regarding the latitude and longitude of the position where the anchor frame 3 is placed.

The arrangement information creation unit 722 creates arrangement information indicating the arrangement of the multiple anchor frames 3 based on the identification information of the multiple anchor frames 3 read by the reading unit 711 and the position information acquired by the position information acquisition unit 721 when the identification information is read. The arrangement information is, for example, an arrangement diagram indicating the arrangement of the multiple anchor frames 3.

The output unit 723 outputs the placement information created by the placement information creation unit 722 to the display device 73.

The display device 73 has a display unit 731. The display unit 731 displays, for example, the arrangement information output from the output unit 723 on the liquid crystal display of the display device 73.

The design information storage unit 724 stores design information indicating the arrangement of the anchor frames 3 at the construction site determined at the time of design. The design information is, for example, a construction drawing indicating the installation position of each anchor frame 3 determined at the time of design. The design information stored in the design information storage unit 724 is input via an input means not shown.

The output unit 723 outputs the design information stored in the design information storage unit 724 together with the placement information created by the placement information creation unit 722 to the display device 73, and the display unit 731 displays the placement information and the design information side by side.

Figure 8 shows an example of the display form of the layout information and design information displayed by the display unit 731. The layout information is a layout drawing showing the actual layout of the anchor frame 3 when the identification information is read from the tag 323 of the anchor frame 3 installed on the pedestal 2. The design information is a construction drawing showing the layout of multiple anchor frames 3 determined at the time of design. The layout drawing and construction drawing are arranged side by side on the display of the display device 73.

8, for example, a square indicates the anchor frame 3 of the first type of lower plate 32 for 300 x 300 [mm], a triangle indicates the anchor frame 3 of the second type of lower plate 32 for 350 x 350 [mm], a star indicates the anchor frame 3 of the third type of lower plate 32 for 400 x 400 [mm], and a circle indicates the anchor frame 3 of the fourth type of lower plate 32 for 500 x 500 [mm]. In FIG. 8, the arrangement of each lower plate 32 in the construction drawing is the same as the arrangement of each lower plate 32 in the layout drawing. In other words, the user can confirm that each lower plate 32 is arranged as shown in the construction drawing by checking the relative position of each lower plate 32 with reference to the display of the display device 73. Because the relative positions can be displayed, even if there is an error in the GPS position information or if the positions of the anchor frames 3 are slightly off from the positions shown on the construction drawings, it is possible to at least check whether the rows themselves are correctly arranged. By checking the arrangement of the lower form plate 32, it is possible to check whether a specific anchor frame 3 is arranged in the appropriate position.

In addition, in the layout drawings and construction drawings, information indicating the latitude and longitude of the position where the lower plate 32 is placed may be displayed near each figure representing each lower plate 32. This makes it possible to confirm the absolute position of each lower plate 32.

Let's return to Figure 7 to continue explaining the functions of the management device 72.

The receiving site information storage unit 725 stores receiving site information indicating the receiving site where the anchor frame 3 is to be received. The receiving site is the construction site where the tag information output device 7 is installed and operated, and where the anchor frame 3 is actually received. The receiving site information includes, for example, information regarding the name of the structure to be constructed at the construction site and the address of the construction site. The receiving site information stored in the receiving site information storage unit 725 is input via an input means not shown.

The determination unit 726 determines whether the delivery destination information read by the reading unit 711 matches the receiving site information stored in the receiving site information storage unit 725. For example, the determination unit 726 determines whether the name of the building indicated in the delivery destination information read by the reading unit 711 matches the name of the building at the receiving site indicated in the receiving site information.

The output unit 723 outputs the determination result by the determination unit 726 to the display device 73, and the display unit 731 displays the determination result by the determination unit 726.

The identification information storage unit 727 sequentially stores the identification information read from the tag 323 by the reading unit 711.

The calculation unit 728 calculates the quantity of the lower form plates 32 for each piece of identification information read by the reading unit 711 as the quantity of anchor frames 3 based on the identification information stored in the identification information storage unit 727. In other words, the calculation unit 728 counts the lower form plates 32 received at the construction site where the tag information output device 7 is installed and operated, sorting them by type, and calculates the quantity of anchor frames 3 by specification (type).

The receiving information storage unit 729 stores the identification information and quantity of the anchor frames 3 to be received at the construction site. For example, the type and quantity of each type of lower form plate 32 to be used at the construction site are input by an input means (not shown) and stored in the receiving information storage unit 729.

The determination unit 726 determines whether the quantity of lower form plates 32 for each identification information calculated by the calculation unit 728 matches the quantity of lower form plates 32 stored in the receiving information storage unit 729. This allows, for example, a determination to be made as to whether the quantity of components received at the construction site matches the quantity of components actually used at the construction site.

The output unit 723 outputs information indicating the quantity for each identification information of the anchor frame 3 calculated by the calculation unit 728 and the judgment result by the judgment unit 726 to the display device 73, and the display unit 731 displays the quantity for each identification information of the anchor frame 3 calculated by the calculation unit 728 and the judgment result indicating whether the quantity is appropriate.

Figure 9 is a diagram showing an example of the display mode of the quantity and judgment result for each identification information of anchor frames 3 displayed by the display unit 731. In Figure 9, the quantity of anchor frames 3 for each specification (type) received at the construction site and the judgment result indicating whether the quantity is appropriate are displayed in a table format. In Figure 9, "OK" is displayed to the right of each quantity, indicating that the amount of anchor frames 3 of each type that will actually be used has been received. Note that if the quantity of each type received does not match the quantity that will actually be used, "NG" can be displayed.

Next, we will explain the processing performed by the tag information output device 7 when receiving the anchor frame 3 at the construction site.

Figure 10 is a flowchart showing an example of the processing of the tag information output device 7 when receiving an anchor frame 3.

When the lower plate 32 receives the cargo, the reading unit 711 reads the identification information and delivery destination information embedded in the tag 323 attached to the lower plate 32 (step S01).

Next, the determination unit 726 determines whether the construction site indicated by the delivery destination information read by the reading unit 711 matches the construction site indicated by the receiving site information stored in the receiving site information storage unit 725 (step S02).

If it is determined that the construction site indicated by the delivery destination information matches the construction site indicated by the receiving site information (Yes in step S02), the output unit 723 outputs the determination result to the display device 73 (step S03), and the display unit 731 displays the determination result.

Then, the identification information read by the reading unit 711 is stored in the identification information storage unit 727 (step S04), and the process proceeds to step S06.

On the other hand, if it is determined that the construction site indicated by the delivery destination information does not match the construction site indicated by the receiving site information (No in step S02), the output unit 723 outputs the determination result to the display device 73 (step S05), and the display unit 731 displays the determination result.

In this case, the identification information read by the reading unit 711 is not stored in the identification information storage unit 727, and the process proceeds to step S06.

Next, it is determined whether or not the receipt of the goods has been completed (step S06). For example, the tag information output device 7 may be equipped with an end button, and the determination unit 726 may determine that the receipt of the goods has been completed when the end button is pressed.

If it is determined that the receipt of the goods has been completed (Yes in step S06), the calculation unit 728 calculates the quantity for each identification information of the anchor frame 3 from the identification information stored in the identification information storage unit 727 (step S07).

Then, the determination unit 726 determines whether the quantity for each identification information calculated by the calculation unit 728 matches the quantity for each identification information stored in the consignment information storage unit 729, and the determination result is output by the output unit 723 to the display device 73 (step S08). The display unit 731 then displays the quantity for each identification information of the anchor frames 3 and information indicating whether the quantity is appropriate, and the processing at the time of consignment is completed.

If it is determined in step S06 that the receipt of the goods has not been completed, the process returns to step S01, and the reading unit 711 reads the identification information and delivery destination information embedded in the tag 323 attached to the lower plate 32 of another anchor frame 3. Note that the determination of No in step S06 is made by the user.

When the anchor frames 3 are received at the construction site, the above process is executed, and the quantity of each identification information of the received anchor frames 3 and information indicating whether the quantity of the received anchor frames 3 is appropriate are displayed on the display device 73.

Next, we will explain the process performed by the tag information output device 7 when checking whether the anchor frame 3 is placed on the specified stand 2.

Figure 11 is a flowchart showing an example of processing when installing the anchor frame 3.

First, after assembling the anchor frame 3 at the construction site, a worker places the anchor frame 3 on the stand 2 according to the construction drawing of the anchor frame 3, by looking at the model written in chalk or the like on the lower form plate 32 of the member that constitutes the anchor frame 3.

The reading unit 711 reads the identification information from the tag 323 on the lower plate 32 of the anchor frame 3 installed on the stand 2 (step S11).

Next, the position information acquisition unit 721 acquires and stores the position information of the lower plate 32 at the time when the identification information is read by the reading unit 711 as the position information of the anchor frame 3 (step S12).

Next, it is determined whether reading of the identification information has been completed (step S13). For example, the tag information output device 7 may be provided with the above-mentioned end button, and when the end button is pressed, the determination unit 726 may determine that reading of the identification information has been completed.

If it is determined that reading of the identification information has been completed (Yes in step S13), the placement information creation unit 722 creates a placement diagram showing the placement of the anchor frame 3 based on the identification information and position information (step S14).

Next, the output unit 723 outputs information indicating the layout drawing created by the layout information creation unit 722 and the construction drawing stored in the design information storage unit 724 to the display device 73, and the display unit 731 displays the layout drawing and the construction drawing on the display (step S15), completing the processing for installing the anchor frame 3.

If it is determined in step S13 that reading of the identification information has not been completed, i.e., if there is an anchor frame 3 for which the identification information has not yet been read, the process returns to step S11 and continues reading of the identification information.

This process allows the worker to compare the layout diagram of the anchor frame 3 displayed on the display device 73 with the construction diagram of the anchor frame established at the time of design, and to verify whether the anchor frame 3 actually placed on the stand 2 is positioned as designed.

For small-scale buildings, layout plans are created for all anchor frames 3 used in the building. For large-scale buildings, the building may be divided into multiple blocks, and a layout plan may be created for each block.

In this embodiment, the identification information read by the reading unit 711 and the position information acquired by the position information acquisition unit 721 are output. Therefore, the worker can easily check whether or not a specific anchor frame 3 selected at the time of design is installed on a specific pedestal 2. As a result, it is possible to prevent installation errors of the anchor frame 3.

In addition, in this embodiment, placement information indicating the placement of multiple anchor frames 3 is created from the identification information and position information. Therefore, the worker can visually check the placement information and confirm whether or not a specific anchor frame 3 selected at the time of design is installed in a specific position. As a result, it is possible to prevent mistakes in installing the anchor frame 3.

In addition, in this embodiment, design information that specifies the installation location of the anchor frame 3 is output. Therefore, by comparing the layout information with the design information, the worker can more easily confirm whether or not the specified anchor frame 3 selected at the time of design is installed on the specified stand 2. As a result, it is possible to prevent mistakes in installing the anchor frame 3.

In addition, in this embodiment, the placement information and design information are displayed simultaneously. Therefore, the worker can more easily check on the display device 73 of the construction management system whether or not the specified anchor frame 3 selected at the time of design is installed on the specified stand 2. As a result, it is possible to prevent mistakes in installing the anchor frame 3.

In addition, in this embodiment, a determination result is output as to whether the receiving site information stored in the receiving site information storage unit 725 matches the delivery destination information read by the reading unit 711. Therefore, the worker can easily check whether the anchor frame 3 has been delivered to the construction site, which is the predetermined delivery destination.

In addition, in this embodiment, the identification information is generated from the captured image. This makes it possible to prevent input errors in the identification information.

In addition, in this embodiment, the quantity of each identification information of the anchor frames 3 received at the construction site is calculated. Therefore, the worker can easily check whether or not a predetermined number of anchor frames 3 have been received at the construction site.

[Other embodiments]
In the above embodiment, the tag 323 has been described as an RF tag. However, the tag 323 is not limited to an RF tag, and may be, for example, a sticker on which a matrix type two-dimensional code or a barcode is printed. In this case, the tag creation device 63 is, for example, a printer that prints the matrix type two-dimensional code or the barcode on a sticker. The tag reading device 71 is, for example, a code reader.

In the above-described embodiment, the columns are square columns, and the planar shapes of the base plate 11, frame 2, lower plate 32, and upper plate 34 are rectangular, but if the columns are other shapes such as circular steel pipes, the base plate 11, frame 2, lower plate 32, and upper plate 34 will also have other shapes to match the columns.

Furthermore, the mounting base 2 need only be capable of adjusting the height of the anchor frame 3, and is not limited to the structure shown in FIG. 1, etc.

In this embodiment, the layout drawing of the anchor frame 3 created from the identification information and position information, and the construction drawing of the anchor frame 3 that was determined at the time of design and specified in advance are displayed on the display at the same time, but it is also possible to display only the layout drawing on the display and have the worker compare the construction drawing at hand with the displayed layout drawing to verify it.

In this embodiment, the layout drawing and the construction drawing are displayed simultaneously on the same screen, but it is also possible to switch between the layout drawing and the construction drawing. Alternatively, the layout drawing and the construction drawing may be displayed superimposed on each other.

In this embodiment, the worker compares the layout drawing and the construction drawing, but the determination unit 726 may automatically determine whether the identification information and position information of the anchor frame 3 placed on the stand 2 match the identification information and position information of the anchor frame 3 defined at the time of design, and the determination result may be displayed on the display.

In this embodiment, a layout diagram is created and displayed based on identification information and location information, but for example, identification information and location information including latitude and longitude may be displayed in a table format.

In this embodiment, the identification information and position information are read from the tag 323 of the lower form plate 32 of the anchor frame 3, i.e., the lower form plate 32 corresponds to the member constituting the anchor frame according to the present invention, but this is not limited thereto, and it may be the upper form plate 34 of the anchor frame 3. In this case, the position information of the upper form plate 34 is read before the foundation concrete 4 is poured and before the upper form plate 34 is removed. Also, the identification information and position information of both the lower form plate 32 and the upper form plate 34 may be used instead of being selective. In this case, the lower form plate 32 and the upper form plate 34 correspond to the member constituting the anchor frame 3 according to the present invention.

The components constituting the anchor frame of the present invention may include at least one of anchor bolt 31, nut 33, nut 35, and washer (not shown). That is, tag 323 in which the identification information and delivery destination information of these components are embedded may be attached directly or indirectly to these components. In this case, when the goods are received, the identification information and delivery destination information embedded in tag 323 are read by reading unit 711, and based on the read information, the quantity of each identification information of these components and information indicating whether this quantity is appropriate are displayed on display device 73.

In the construction management system of this embodiment, the tag information generating device 6 is equipped with an information acquiring device 61. However, the tag information generating device 6 does not have to be equipped with an information acquiring device 61. In this case, for example, the input device 64 accepts input of identification information of the anchor frame 3 from a user. This information may be coded by the tag information creating unit 631 and written to the tag 323 by the writing unit 632.
