The present invention relates to a construction site management and analysis system using a computer network, and more specifically, a construction company, a steelmaking company, a rebar processing company and a rebar assembly company that perform the same construction work with each other as a computer network. This is the minimum unit for managing the reinforcing bars, so that the rebar processing slip can be created online. Through the generated rebar processing slip, the user can aggregate the information about the reinforcing bar to be used in the construction site in the desired aggregation method online. In addition, the present invention relates to a construction site reinforcement quantity management and analysis system using a computer network that allows a combination of a plurality of reinforcing bars to be online in order to minimize the loss of reinforcing bars based on the generated reinforcing sheet.

In general, reinforcing bars having various shapes and lengths are used in large quantities according to members such as foundations, columns, walls, beams, slabs, and the like. The construction associates who are closely related to the reinforcement work in the construction site include the contractor who receives and constructs the entire construction work, the steelmaker who produces the reinforcing bar in the construction site, and the reinforcing bar in the size and shape required at the construction site. There are reinforcing companies that process and reinforcing bars that assemble the machined steel in the construction site. Rebars used in construction sites are relatively expensive, are used in large quantities, and the amount of scrap that is discarded into scrap when processed and assembled is significant. In addition, it is necessary to systematically share, manage and analyze the reinforcing bar information necessary for the progress of reinforcing work among the above-mentioned construction parties.

However, most of the rebar quantity management in the conventional construction site is done independently for each construction person on the offline. In other words, each construction official writes information about the rebar needed for the construction by hand or using a general-purpose spreadsheet program whenever necessary. As shown in Figure 1a and 1b conventional reinforcing bar information (rebar processing request and rebar plant factory) is often made by hand, the reinforcing bar information is mainly related to the company using FAX or E-MAIL, etc. There is a problem that occurs easily because it is delivered to. In addition, other construction personnel who received the reinforcing bar information had to troubleshoot and edit the received reinforcing bar once again in order to meet their own management and analysis methods.

In the conventional reinforcing management method in the construction site, the construction company had a problem that it is difficult to accurately manage the rebar construction, such as rebar purchase and monthly ready management. In other words, a construction company generally estimates that about 3% of the scrap is discarded when purchasing the necessary rebar at the construction site, and adds it as a premium. By the way, most steelmakers are producing only the length of 8M length as the basic standard. For example, if 6.8M length of rebar is needed, it is cut as much as necessary in 8M steel bar and the remaining 1.2M part is processed with scrap metal. As a result, a loss of about 15% is generated in excess of the estimated premium (3%), and thus there is a problem that the amount of rebar is always insufficient at the construction site. In addition, the construction company pays the construction cost to the rebar processing company or the rebar assembly company based on the reinforcement amount (tons) assembled every month. In this case, since there is no means to accurately calculate the assembled rebar amount, There is a problem that the construction period is long due to the dispute often occurs, and in fact, the rebar cost increases because the assembled rebar amount always exceeds the pre-calculated rebar amount, and thus there is a serious problem that the construction cost increases.

In addition, in the conventional reinforcement management method in the construction site, the construction company is unable to systematically manage and analyze the reinforcing bar information required at the construction site, most of them order only the steel mill length of 8M. Therefore, steelmakers are unable to produce the rebars in various lengths due to the lack of accurate information on the rebars ordered by the construction company. There is a problem that the amount of reinforcing bar is significant and eventually a great loss for the national economy.

The present invention was created in order to solve the problems of the rebar quantity management system of the conventional construction site as described above, the construction personnel, steelmakers, rebar processing companies and rebar assembly companies that are the construction personnel performing the same construction computer It is the minimum unit for managing the rebars connected to each other through the network so that the rebar processing slip can be created and shared online.The generated rebar processing slip allows the user to collect information on the rebars that will be used in the construction site online. The number of rebars that are discarded as scrap metal at the construction site can be aggregated, and the multiple rebars can be combined online according to the length of the retrieval to minimize the loss of rebars based on the generated rebar processing slips. To reduce rebar and construction costs By sharing the same reinforcing bar information between construction personnel, prevent disputes in advance to facilitate public works, and systematically manage and analyze the information of reinforcing bars required for construction sites. Its purpose is to enable the production of precision lengths to help the national economy by significantly reducing the discarded portion of the rebars used in the construction site.

In order to achieve the above object, the present invention uses a computer network through which a server site, a plurality of builders computers, a plurality of steelmaker computers, a plurality of reinforcing machine computers, and a plurality of reinforcing bar computers are interconnected through a network. In the system related to the management and analysis of construction site rebar quantity,

The server site includes a server computer equipped with a main program, a rebar processing slip generating program, a rebar information aggregation program, a rebar information combination program, and other programs;

Mount). The rebar processing document generating program 212 is a program for generating a rebar processing slip as a minimum unit for managing rebars at a construction site. The rebar processing slip according to the present invention uses a standard shape DB of a processed rebar stored in a database to be described later. Is generated by inputting basic information about dimensions, number, used part, etc. for rebar used in construction site. These reinforcing slips can be shared and used by construction personnel who access this server site through a computer network. The reinforcement information aggregation program 213 selects the reinforcement slip generated according to the rebar processing slip generation program 212, and then selects an aggregation method desired by the user, for example, a floor, a part, a date, or an aggregate length by precision length. It is a program to perform the process of counting rebars to be used in construction sites. Reinforcing bar information combination program 214 is a program to perform the process of combining the information of the reinforcing bar to be used in the construction site according to the selected reinforcing bar selected by the user after the information of the one or more bars to be used in the construction site. In other words, the reinforcing bar information combination program, for example, if 4.5M rebar and 3.5M rebar is required at the construction site, the amount of reinforcing bar is not used by selecting the combination of the two bars to use the 8M long precision length This program can be minimized. The reinforcing bar selected by the user in the reinforcing bar information combination program is composed of the reinforcing bar having a length of 0.5M interval from 3M to 12M, and further, the length of the reinforcing bar may be freely added by the user if necessary. The main program 211 is a program that is linked with the programs to perform the overall process of the method for the management and analysis of construction site reinforcement quantity using a computer network according to the present invention.

Registered member DB (221) is a member of the construction personnel performing the reinforcement work at the construction site, namely the members (name, address, telephone number, etc.) registered in the construction company, steel mill, rebar processing company, and rebar assembly company Save it. Standard shape DB of the processed reinforcing bar (222) is the name, specification (rebar diameter), strength, processing shape of reinforcing bar, rebar length, number, location of use of rebar, length of rebar, Information about the number, weight, and the like is stored. The standard shape DB 222 of the processed reinforcing bar is provided so that the user can easily select when generating the reinforcing sheet according to the present invention. The generated reinforcing slip DB 223 stores information on the generated reinforcing slips when each construction person accesses the server site according to the present invention to generate reinforcing slips, and the server according to the present invention. It can be shared by the construction officials accessing the site and aggregated or combined in the manner required by each construction representative. Aggregated reinforcement information DB (224) when the user aggregates the reinforcing bars used in the construction site according to the aggregation method by floor, part, date, and precision length from the pre-generated reinforcing billing table as needed, Save information about rebar. In addition, the combined reinforcing bar information DB 225 stores information about the combined reinforcing bars when the user combines a plurality of processed bars according to the reinforcing bars in order to minimize the loss of the bars used in the construction site. In addition to the data stored in the DBs, the other DB 225 stores various data necessary for performing the method according to the present invention.

Hereinafter, referring to FIG. 3, a method related to construction site rebar quantity management and analysis using a computer network according to an embodiment of the present invention will be described in more detail.

First, the construction personnel performing the reinforcing work at the construction site, that is, the construction company, steelmaker, rebar processing company, and the rebar assembly companies are connected to the server site according to the present invention (S301). At this time, the server site computer checks whether the connected user is a member (S302), and if not, proceeds with a separate member registration procedure (S303). If it is determined in step S302 that the member is a member, the center server computer authenticates the user based on the stored sales member DB (S304).

The user authenticated member decides whether to generate a rebar processing slip for the rebar to be used in the construction site (S305). If the member decides to generate the rebar processing document, the member inputs various basic information about the rebar processing document, for example, the document number, the site, the floor, the part, the delivery date, etc. (S306). Next, the member selects a standard shape for the reinforcing bar actually used in the construction site from the standard shape DB 222 of the reinforcing bar stored in the server site 20 according to the present invention (S307), and various kinds of rebars to be used in the construction site. Information, for example, a dimension, a use position, the number, etc. are input (S308).

4 is a view showing an example of a screen for inputting the basic information of the reinforcing bar to be used to generate the reinforcing steel sheet according to the present invention. As shown in FIG. 4, the user may select or input various basic information on the rebar processing slip to be generated and various information on the rebar to be used at the construction site by an input means such as a mouse or a keyboard. The name, specification (rebar diameter), strength, rebar shape, rebar length, number, location of use, rebar length, number of rebars, weight, etc. for at least one rebar can be obtained from the database of the server site 20. It is previously stored in the standard shape DB 222 of the steel bar processed in 22. As shown in FIG.

Thereafter, the server site preliminarily generates the rebar processing slip according to the information entered by the member, and the member checks whether the generated rebar processing slip matches the information input by the user (S309). If it is determined in step S309 that the generated reinforcement slips match the information entered by the member, the reinforcement slips are finally generated (S310). However, if the determination result of the step S309, the generated reinforcement slip does not match the information input by the member, the process is returned to step S305 to perform again.

Next, by inputting the information required for the reinforcement work, it is confirmed whether to continue the procedure for the member who finally created the rebar processing slip (S311). If the member requests to continue the procedure, the process returns to step S304. However, if the member decides not to proceed with the procedure any more, the server site terminates the procedure (S312).

On the other hand, if the member connected in step S305 decides not to generate the rebar processing slip, the server site checks whether or not to aggregate the reinforcing bars to be used in the construction site (S401). As a result of the above step S401, if the member requests the counting of the reinforcing bars used in the construction site, the member to select one or a plurality of reinforcing slips of his or her desired from the already created reinforcing slips (S402). Next, the user selects the required aggregation method for the rebar used in the construction site (S403). In this case, the user may aggregate the reinforcing bar by the list used in the reinforcing slip sheet, such as by floor, part, date, precision length, rebar diameter, or reinforcement strength, and the aggregation method may be combined with one or more. . 5A and 5B respectively show an example of a screen in which the used reinforcing bar counting result table is generated by the counting method for each part and the counting method for each length according to the present invention.

The server site preliminarily generates the used rebar counting result table using the rebar information counting program 213 according to the counting method selected by the user for the rebar slip selected by the user (S404). Check whether the generated reinforcing bar aggregate result table matches (S405).

If the determination result of the step 405, if the generated reinforcing bar counting table and the selected information selected by the member is matched to finally generate the used reinforcing bar counting result table (S406), and then go to step S311 and whether the member continues the procedure To determine. However, if the result of the determination of step 405 does not match the generated used rebar counting table and the member's selected aggregate information, the process returns to step S401 to determine whether to continue the procedure.

On the other hand, if the member decides not to count the rebars used in step S401, the server site checks whether or not to perform a combination for the rebars to be used in the construction site (S501), as a result of the step S501, the member is used in the construction site If a combination of reinforcing bars is required, the member selects information on one or a plurality of reinforcing bars to be used in the construction site (S302), and selects the reinforcing bars to perform the combination (S503). According to the current KS D 3504 standard, the rebar bar is produced at 0.5M intervals from 3M to 12M. The 8M length of the reinforcing bar is the basic standard and the remaining reinforcing bar is produced only by pre-order. Furthermore, the length of the rebar can be added freely by the user if necessary.

Next, the server site preliminarily generates a table of used rebar combination results for the selected rebars using the rebar information combination program 214 according to the rebar selected by the user for one or a plurality of rebars selected by the user ( S504), the member checks whether the combination information selected by the user and the generated reinforcing bar combination result table match (S505).

If it is determined in step S505 that the generated rebar combination table and the combination information selected by the member match, the server site finally generates a use rebar combination result table (S506), and then moves to step S311 and the member Decide if you want to continue the process. However, if the determination result of step S505 does not match the generated used reinforcing bar combination table and the combination information selected by the member, the process returns to step S501 to determine whether to continue the procedure. FIG. 6 is a view showing an example of a screen in which reinforcing bars are combined so that a minimum reinforcing bar loss is obtained based on a reinforcing work sheet generated according to the present invention. One example is shown.

On the other hand, if, as a result of step S501, the member decides not to perform the use reinforcing bar combination to perform the step S311 to determine whether to continue the procedure.
