FIG. 1 is a block diagram showing the configuration of a building material management system 100 according to an embodiment of the present invention. The building material management system 100 is a system for ensuring traceability in the distribution flow of building materials. The building material management system 100 is a system that manages building materials using identification information. FIG. 2 is a conceptual diagram showing the relationship between the parties involved in the distribution flow of building materials and the flow of building materials. FIG. 3 is a conceptual diagram showing the flow of distribution of building materials. FIG. 4 is a conceptual diagram showing an example of information exchange using the building materials management system 100. As shown in FIG.

First, with reference to FIGS. 2 and 3, the flow of distribution of building materials using the building materials management system 100 and the building materials management method according to the present embodiment will be described. The building material 20 is a long member extending in a predetermined direction among materials used for construction. Examples of the building materials 20 include steel pipes, channel steel, H-section steel, angle steel, flat steel, and bar steel. In the following description, an example in which a rectangular steel pipe is used as the building material 20 will be described.

As shown in FIG. 2, among wholesalers B such as trading companies and special agents, primary wholesaler B1 orders products from building materials manufacturer A (route R1). In response to this, the building material manufacturer A manufactures the building material 20 (see FIG. 3). In addition, the building materials manufacturer A delivers the building materials 20 in the quantity ordered, together with the mill sheet M (see FIG. 3), to the primary wholesaler B1 (route R2). At this time, the primary wholesaler stocks the long building materials 20 as delivered.

A construction company D, such as a general contractor or a design office, designs a building and makes a construction plan, etc., and then orders the necessary steel frames from the fabricator C (route R3). In addition, the "steel frame" here means a building material in a processed state used for erection. The fabricator C orders building materials of the required length and quantity for processing steel frames from the secondary/tertiary wholesaler B2 (route R4). Note that the mill sheet M is a document that certifies the material of building materials. The mill sheet M is stamped with the seal of the shipper. In the example of FIG. 3, the seal of the building material manufacturer A is indicated by "XX", the seal of the primary wholesaler is indicated by "○○", and the seal of the secondary and tertiary wholesalers is indicated by "△△".

The secondary/tertiary wholesaler B2 orders the building materials of the length and quantity according to the order from the fabricator C from the primary wholesaler B1 (route R5). The primary wholesaler B1 cuts the building material 20 at the building material cutting site Ba according to the order. As a result, the primary wholesaler B1 delivers the cut building material 25 (see FIG. 3) cut to the required length to the secondary/tertiary wholesaler B2 together with the mill sheet (route R6). Further, the secondary/tertiary wholesaler B2 delivers building materials of the length and quantity according to the order to the fabricator C (route R7).

However, there are cases where the secondary/tertiary wholesaler B2 has a building material cutting site Ba. In this case, the secondary/tertiary wholesaler B2 may cut the building materials 20 and deliver the cut building materials 25 to the fabricator C. . Also, the fabricator C may directly place an order with the primary wholesaler B1. In addition, uncut building materials 20 may be delivered to the fabricator C in some cases. In the example shown in FIG. 3, the fabricator C3 receives cut building materials 25 from the secondary/tertiary wholesaler B2. Fabricator C2 receives cut building materials 25 from primary wholesaler B1 and secondary/tertiary wholesaler B2. The fabricator C1 receives uncut building materials 20 from the primary wholesaler B1.

The fabricator C processes the delivered building materials to create the steel frame 30 at the steel frame processing plant Ca (see FIG. 3). At this time, the fabricator C and the construction company D conduct an on-site inspection at the steel frame processing plant of the fabricator C (route R8). After passing the witnessed inspection, the fabricator C delivers the steel frame to the construction site Da (route R9).

Next, the configuration of the building material management system 100 according to the present embodiment used in the distribution described above will be described with reference to FIG. As shown in FIG. 1, the building material management system 100 includes an identification information assigning unit 1, an identification information transmitting unit 2, a product information transmitting unit 3, an information reading unit 4, and a server . A building material manufacturer A has an identification information assigning unit 1 , an identification information transmitting unit 2 , and a product information transmitting unit 3 . The wholesaler B has a product information transmission section 3 and an information reading section 4 . The fabricator C has an information reader 4 .

The identification information assigning unit 1 assigns identification information for specifying the building material 20 to the building material 20 . Only one piece of identification information is set for each building material 20 . Identification information is information represented by numbers, letters, symbols, or combinations thereof. The identification information provision unit 1 forms the identification information in a readable form on the surface side of the building material 20 . As a readable mode, there is a method of displaying identification information in the form of a mark such as a bar code or QR code (registered trademark). Further, as a readable form, the identification information may be directly written on the surface side of the building material 20 . As a readable form, the identification information may be held in a medium such as an electronic tag. The surface side refers to any plane side of the entire peripheral surface of a building material having an open cross section such as H-shaped steel, and refers to any plane side of the outer peripheral surface side of a building material having a closed cross section such as a steel pipe. The identification information is associated with product information indicating product characteristics of the building material 20 stored in the server 10 . Details of the product information will be described later.

The identification information assigning unit 1 includes a calculation unit for setting identification information for the new building material 20 . However, the identification information providing unit 1 may acquire identification information set at another location. The identification information adding unit 1 also includes a device for forming a bar code or QR code on the building material 20 . The identification information providing unit 1 may employ marking or laser marking as a method of forming identification information. According to these forming methods, it is possible to quickly perform printing over the entire length of the building material 20, reduce peeling and damage caused by labels, and achieve a lower cost than electronic tags. However, the identification information providing unit 1 may form the identification information by attaching a label. When the identification information is held in the electronic tag and formed on the building material 20, the identification information providing unit 1 has a device for inputting the identification information into the electronic tag.

The identification information providing unit 1 continuously forms identification information on the surface side of the building material 20 along the longitudinal direction of the building material 20 . As shown in FIG. 5, a plurality of pieces of identification information 21 are arranged on the outer surface of the building material 20 along the longitudinal direction. As a result, a row 22 of identification information 21 extending from one end 20a to the other end 20b in the longitudinal direction of the building material 20 is formed. One piece of identification information 21 serves as an independently readable display section. A plurality of identical display units are repeatedly arranged in the column 22 . A row 22 of identification information 21 is formed on one side surface 20 c of the four side surfaces of the building material 20 . Further, the row 22 of the identification information 21 is formed in the widthwise center of the side surface 20c. On the surface of the side surface 20c, areas formed above and below the row 22 of the identification information 21 in the width direction are blank spaces where other information (for example, product information) is not written. Note that the rows 22 of the identification information 21 may be formed in a plurality of rows on the side surface 20c, or may be formed on other side surfaces in addition to the side surface 20c.

As shown in FIG. 5(b), the identification information 21 is displayed here as a bar code. Within the row 22, the same bar code pattern is repeatedly formed along the longitudinal direction. In addition, the bars of the barcode are formed so as to extend in the width direction. However, the orientation of the barcode is not particularly limited, and may be formed in any orientation, for example, the bar may be formed in an orientation extending in the longitudinal direction.

The state in which the identification information 21 is continuous will be described in further detail. The state in which the identification information 21 is continuous means that when a cut building material 25 having an arbitrary length is cut out from the building material 20 at an arbitrary position in the longitudinal direction, the cut building material 25 can be identified regardless of the position and length. At least one piece of identification information 21 is included. That is, even if a plurality of pieces of identification information 21 are formed in the longitudinal direction of the building material 20, if the dimension of the gap in the longitudinal direction between the pieces of identification information 21 is extremely large, the building material 25 may be cut from the portion of the gap. Since the identification information 21 is not included when the .

As shown in FIG. 6, the dimension in the longitudinal direction of each piece of identification information 21 is L1. Let L2 be the dimension of the gap SP between the pair of identification information 21 . The dimension L1 is not particularly limited because there is a difference between when the identification information 21 is indicated by a barcode and when it is indicated by a QR code, but it may be set to a readable width, and may be set to about 6 to 800 mm. . The lower limit of dimension L2 is preferably about 150 mm, but it may be 0 mm (that is, gap SP is not formed). Alternatively, if the gap SP is formed due to the convenience of setting the barcode printing device, the lower limit of the dimension L2 may be the minimum size of the gap SP formed due to restrictions during the printing. Note that the identification information 21 may be formed at equal pitches in the longitudinal direction. That is, the dimension L2 of the gap SP may be constant. However, the identification information 21 does not have to be at equal pitches in the longitudinal direction. When the building material 20 is a rectangular steel pipe, as an example of the size, the length is set to 13 m, and the width is set to about 150 mm×150 mm to 1000 mm×1000 mm.

The upper limit of the dimension L2 of the gap SP is not particularly limited, and may be appropriately set in consideration of various factors such as the type of building material 20, customer requirements, and the size of the cutting device. Also, the sum of the dimension L1 and the dimension L2 may be 800 mm or less, preferably about 600 mm or 650 mm. Furthermore, if the minimum dimension L3 of the cut building material 25 is set according to the agreement at the time of sale or the specifications of the cutting device, the dimension L2 may be within the following range. That is, if the relationship of "dimension L3≧dimension L2+(2×dimension L1)" holds, the cut building material 25 can include at least one piece of identification information 21 regardless of the position of the cut surface. Note that FIG. 6 shows the state of "dimension L3=dimension L2+(2×dimension L1)". Therefore, the dimension L2 may be set within the range of "dimension L2≦dimension L3−2×dimension L1". Regarding the dimension L4 that satisfies the relationship of "dimension L1<dimension L4<dimension L2+2×dimension L1", the cut building material 25 may contain one piece of identification information depending on how the cut surface is taken. 6, the identification information 21 is cut in the middle, and the cut building material 25 does not contain a complete piece of identification information. Therefore, by setting the size of the gap SP to "dimension L2 ≤ dimension L3-2 x dimension L1", the cut building material 25 can include at least one piece of identification information 21 regardless of the cutting position. can.

In addition, the identification information 21 may be continuous in the longitudinal direction, and is not necessarily formed at the same position in the circumferential direction of the building material 20 (when the center line extending in the longitudinal direction is set, the direction surrounding the center line). It does not have to be. That is, when the building material 20 is cut at a plurality of positions in the longitudinal direction, it is sufficient that the identification information 21 can be confirmed at any one of the four side surfaces of each of the plurality of cut building materials 25. No problem arises even if the positions of the information 21 are different from each other in the circumferential direction. For example, as shown in FIG. 7A, a row 22 of identification information 21 in one region in the longitudinal direction is formed on a side surface 20c, and a row 22 of identification information 21 in other regions is formed on a different side surface 22d. may be The identification information 21 at the end of the row 22 on the side surface 20c and the identification information 21 at the end of the row 22 on the side surface 20d are continuous in the longitudinal direction. Alternatively, as shown in FIG. 7B, each piece of identification information 21 may be arranged to form two columns 22A and 22B. The identification information 21 in the column 22A and the identification information 21 in the column 22B are formed alternately. Therefore, when the rows 22A and 22B are viewed in combination, each piece of identification information 21 is continuous in the longitudinal direction.

A state in which the identification information 21 is continuous in the longitudinal direction is a state in which a plurality of pieces of identification information 21 are repeatedly present along the longitudinal direction. The state includes not only a state in which only the identification information 21 is connected, but also a state in which information other than the identification information 21 exists between the identification information 21 and the other identification information 21 . Specifically, as shown in FIG. 9, in addition to the identification information 21, the building material 20 may have product information 28 continuous in the longitudinal direction. The product information 28 is part of the product information written directly on the building material 20 . Here, the product information 28 displays the name of the building material manufacturer (NSMP is a registered trademark), the standard (BCR is a registered trademark), the product name, and the like. In addition, in FIG. 9, since the identification information 21 may be displayed with a bar code or a QR code, it is indicated by an outline square.

The identification information transmission unit 2 and the product information transmission unit 3 include a processor, memory, storage, communication interface, and user interface, and are configured as general computers and mobile terminals such as smartphones and tablet terminals. The processor is a calculator such as a CPU (Central Processing Unit). The memory is a storage medium such as ROM (Read Only Memory) or RAM (Random Access Memory). The storage is a storage medium such as an HDD (Hard Disk Drive). A communication interface is a communication device that implements data communication. A user interface is an output device such as a liquid crystal or a speaker, and an input device such as a keyboard, a touch panel, or a microphone. The processor controls memory, storage, communication interface, and user interface, and implements functions of an identification information transmission unit 2 and a product information transmission unit 3, which will be described later. The identification information transmission unit 2 and the product information transmission unit 3, for example, load programs stored in the ROM into the RAM, and execute the programs loaded into the RAM by the CPU, thereby realizing various functions. The identification information transmission unit 2 and the product information transmission unit 3 may be configured by one device, or may be configured as different devices.

The identification information transmission unit 2 transmits the identification information assigned to the building material 20 by the identification information attachment unit 1 to the server 10 . On the production line, the identification information adding unit 1 sets identification information for the new building material 20 and forms the identification information on the building material 20, while the identification information transmitting unit 2 transmits the newly set identification information. to the server 10 (see FIG. 4).

The product information transmission unit 3 transmits product information indicating product characteristics of the building material 20 to the server 10 . The product information includes the mechanical properties, chemical composition, etc. of the building material 20, which may be described in the aforementioned mill sheet. The product information may include, for example, standards, member symbols, cross-sectional dimensions, length, number of pieces, mass, steelmaking numbers, production numbers, strength test results, chemical compositions, plating deposits, and the like. The product information may also include confirmation information that corresponds to the seal of the shipper. In addition, product information may include information such as company name and product name. When a tester prepares a mill sheet by conducting various tests on the production line, the product information transmission section 3 transmits the product information to the server 10 (see FIG. 4). Here, on the production line, the place where the identification information is given and the place where the test for preparing the mill sheet are performed are provided at different places, and each process is also executed at different timings. Therefore, the product information transmission section 3 transmits the product information at a timing different from the timing at which the identification information transmission section 2 transmits the identification information.

The information reading unit 4 includes a processor, memory, storage, communication interface, and user interface, like the identification information transmitting unit 2 and the product information transmitting unit 3 described above. The processor integrates memory, storage, communication interface, and user interface, and implements the functions of the information reading section 4 . The information reading unit 4 reads identification information 21 formed on the building material 20 . The information reading unit 4 also transmits the read identification information 21 to the server 10 and requests the product information linked to the identification information 21 . The information reading unit 4 displays the product information acquired from the server 10 based on the read identification information to the user. The information reading unit 4 may be composed of a mobile terminal such as a smart phone or a tablet terminal. In this case, the user can easily read the identification information during an examination. The information reading unit 4 may be a reading device (and a computer equipped with the reading device) for reading bar codes and electronic tags.

The server 10 includes a processor, a memory, a storage, a communication interface, and a user interface, like the identification information transmission section 2 and the product information transmission section 3 described above. The processor controls memory, storage, communication interface, and user interface, and implements the functions of the server 10, which will be described later. The server 10 may be composed of a plurality of computers. Server 10 may be a cloud server.

The server 10 includes an information acquisition section 11 , an information processing section 12 and an information transmission section 13 . The information acquisition section 11 acquires identification information from the identification information transmission section 2 and product information from the product information transmission section 3 . The information acquisition unit 11 also receives a request from the information reading unit 4 to retrieve the product information related to the identification information. The information processing section 12 associates the identification information with the product information. When the information acquisition unit 11 acquires the product information about the building material 20 specified by the identification information from the product information transmission unit 3, the information processing unit 12 associates the product information with the corresponding identification information. , to be stored as data. Further, when identification information is transmitted from the information reading unit 4 and product information corresponding to the identification information is requested, the information processing unit 12 searches the stored data and calls up the product information. When receiving a request to retrieve product information related to identification information, the information transmission unit 13 transmits product information linked to the requested identification information.

Specifically, as shown in FIG. 4, when the identification information assigning unit 1 sets the identification information for the building material 20 in the manufacturing line and forms the column 22 of the identification information 21 on the building material 20, the identification information transmitting unit 2 transmits the set identification information to the server 10 . At this time, the information processing section 12 of the server 10 determines a link destination corresponding to the identification information within the server 10 . After that, when the product information is acquired during the test of the building material 20, the product information transmitting unit 3 transmits the acquired product information to the server 10 as the product information corresponding to the identification information of the building material 20 to be tested. . At this time, the information processing section 12 of the server 10 stores the product information in the link destination corresponding to the identification information. As a result, the identification information and the product information are linked in a one-to-one relationship. Thereafter, at the time of or after shipping the building materials 20, the information reading section 4 reads the identification information 21 and transmits the read identification information to the server. As a result, the server 10 calls up the product information from the link destination corresponding to the transmitted identification information, and transmits it to the information reading section.

Next, the procedure of the building material management method according to this embodiment will be described with reference to FIG. As shown in FIG. 8, in the building materials manufacturer A, the identification information providing unit 1 gives identification information to the building materials 20, and the identification information sending unit 2 sends the identification information to the server 10 (step S1: identification information providing step , identification information transmission step). When the building material manufacturer A assigns identification information to the building materials 20 , one piece of identification information may be assigned to one building material 20 . In this case, different identification information is assigned to a plurality of building materials 20 made from the same hot coil (raw material). Alternatively, building material manufacturer A may give the same identification information to a plurality of building materials 20 made from the same hot coil (raw material). In this case, it is possible to reduce the labor of work in the production line.

The information acquisition unit 11 of the server 10 acquires the identification information transmitted from the identification information transmission unit 2 of the building material manufacturer A (step S2). At this time, the information processing section 12 determines the link destination corresponding to the identification information in the server 10 . Next, when the product information is acquired by the building material manufacturer A, the product information transmission unit 3 transmits the product information corresponding to the identification information of the target building material 20 to the server 10 (step S3: product information transmission step). . The information acquisition unit 11 of the server 10 acquires the product information transmitted from the product information transmission unit 3 of the building material manufacturer A (step S4). The information processing unit 12 stores the product information linked to the identification information in the link destination corresponding to the identification information in the server 10 (step S5). After completing the above processes, the building material manufacturer A ships the building material 20 .

The wholesaler B affixes a seal to the mill sheet of the delivered building material 20 . At this time, the product information transmitting unit 3 of the wholesaler B transmits confirmation information indicating that the confirmation by the wholesaler B has been completed to the server 10 as product information (step S6). The information acquisition unit 11 of the server 10 acquires the product information transmitted from the product information transmission unit 3 of the building material manufacturer A (step S7: product information transmission step). The information processing unit 12 stores the product information linked to the identification information in the link destination corresponding to the identification information in the server 10 (step S8). After the above processing is completed, the wholesaler B cuts the building materials 20 to the length according to the order and ships the cut building materials 25 . Note that the processing of steps S6 to S8 may be omitted. For example, when the same identification information is given to a plurality of building materials 20 made from the same hot coil (raw material), the processing of steps S6 to S8 may be omitted.

The fabricator C executes an inspection process for inspecting the cut building material 25 cut at an intermediate position in the longitudinal direction. In the inspection process, product information is acquired from the server 10 by reading the identification information formed on the cut building material 25, and the acquired product information and design information set in advance for the cut building material 25 are inquired. The inspection is done by.

Specifically, the identification information reading unit 4 reads the identification information formed on the cut building material 25 (or the steel frame 30 after processing) (step S9: inspection step). Further, the identification reading unit 4 requests the product information corresponding to the read identification information from the server 10 (step S10: inspection step). At this time, the identification information reading unit 4 transmits the read identification information to the server 10 together with the request for the product information. The information acquisition unit 11 of the server 10 acquires a request from the identification information reading unit 4 of the fabricator C (step S11: inspection step). The information processing unit 12 introduces the acquired identification information to the stored information (step S12: inspection step). The information processing unit 12 calls the product information from the link destination corresponding to the acquired identification information. The information transmitting unit 13 transmits the called product information to the information reading unit 4 of the fabricator C (step S13: inspection step). Thereby, the information reading section 4 of the fabricator C acquires the transmitted product information (step S14: inspection step). Thereby, the fabricator C can refer to the product information corresponding to the cut building material 25 to be inspected. The fabricator C can inspect the cut building material 25 by referring to the acquired product information and design information. With the above, the processing of FIG. 8 ends.

Next, the building material management method, the building material management system 100, and the functions and effects of the building materials according to this embodiment will be described.

The building material management method according to the present embodiment includes an identification information adding step of adding identification information for specifying the building material 20 to the building material 20 . The identification information is formed in a readable form on the surface side of the building material 20 . Further, the identification information is associated with product information indicating product characteristics of the building material 20 stored in the server 10, and the product information can be obtained from the server 10 by reading the identification information. Therefore, by reading the identification information formed on the surface side of the building material 20 , the user can obtain the product information linked to the identification information from the server 10 . Here, in the identification information providing step, the identification information is continuously formed on the surface side of the building material 20 along the longitudinal direction of the building material 20 . Therefore, when the cut building material 25 is cut out at an arbitrary position and length in the longitudinal direction of the building material 20, the cut building material 25 can include the identification information. Therefore, the user can read the identification information formed on the cut building material 25 and obtain the product information accurately. As described above, the traceability of the building material 20 can be improved.

In addition, in the building material management method according to the present embodiment, the cut building material 25 that is cut halfway in the longitudinal direction of the building material 20 may have at least one piece of identification information along the longitudinal direction of the building material 20 .
