Architectural drawing analysis and processing method using a computer according to an embodiment of the present invention having the above steps goes through the following process.

1 and 2, in order to derive a list of reinforcing bars that require processing, first, standard properties such as diameters and lengths of reinforcing bars are coded and stored (S1). Then, text data is coded in a predetermined form in advance so as to be identified around a reinforcing bar included in a drawing that can be displayed on a screen of a computer, for example, an architectural drawing drawn by Auto CAD. Then, the building drawing inputted with the text data is input to the computer (S3). 4 illustrates an example of inputting a building drawing drawn by the Auto CAD. The architectural drawing includes reinforcing bars for the construction of buildings or bridges, and predetermined texts are coded in a predetermined form so as to be identified around the reinforcing bars. This text contains information about the diameter and length of the rebar. 3 shows a code table for encoding standard properties such as diameter and length of the reinforcing bar, and standard properties of the reinforcing bar are represented by text. With reference to FIG. 3, what the said text shows is demonstrated. The text consists of three alphabets, such as PEX. The first and third characters are alphabets and the second is Arabic numerals, such as P7L. Here, if the text consisting of three alphabets such as PEX is described first, this text format indicates that the shape of the reinforcing bar is an “one” shape that is not bent, and the first alphabet indicates the diameter of the bar and the second The alphabet represents the length of the reinforcing bars and is divided into units of 1000 mm. The third alphabet also represents the length of the reinforcing bars and lengths less than 1000 mm. Therefore, as shown in FIG. 2, PEX represents a rebar having a radius of 22 mm, E represents a reinforcing bar length of 4000 mm divided by 1000 mm, and the last letter X represents a reinforcing bar of 1000 mm or less. It is 250 mm in length. Therefore, PEX indicates that the total length of the rebar is 4250 mm, the radius is 22 mm, and the shape is 'one' shaped. On the other hand, the type in which the Arabic numerals are written in the middle, such as P7L, indicates the shape of “??”, which has been bent once by 90 degrees. The last letter represents the total length of the reinforcing bar, including the length of the bend, so P7L indicates that the reinforcing bar is 22 mm, bent once from 700 mm to 90 degrees and the total length of the bar is 5500 mm. The total length of the reinforcing bar is 5500 mm, indicating that it is bent once by 90 degrees at 700 mm from one end of the reinforcing bar, and the radius of the bar is 22 mm.

Subsequently, the area to be analyzed for drawing in the architectural drawing including the text is designated with a mouse or a keyboard (S4). Then, it is determined whether there is text (S5), and if there is text, text is extracted (S6). Then, the text is detected (S7) whether or not the text is in accordance with the predetermined text format as described above, and returns to the step (S5) to determine whether there is text if the text does not match the format. If the text fits the format, it is displayed as a rebar list (S8) and stored in the rebar list file (S9). The reinforcing bar list is output (S10). The reinforcing bar list may be output as a general document or may be output as an Auto CAD file. An example of the rebar drawn in FIG. 5 is illustrated.

The rebar list derived as described above is a reinforcing bar necessary for the construction of a building or a bridge and is to be processed from raw materials of the reinforcing bar. When processing the reinforcing bar from raw materials, it is necessary to derive from which raw material the selected reinforcing bar should be processed. Hereinafter, a process of performing such precision derivation will be described.

6 is a flow chart for precision drawing, and the screen shown at the time of precision drawing is shown in FIG. Referring to FIGS. 6 and 7, a precision derivation target is selected from the rebar list stored in the rebar list file in the above-described process (S41). That is, to select the target bars to be processed from the list of rebars. This selection can select all of the rebars stored in the rebar inventory, or select some of them if they are already in stock. In this embodiment, the reinforcing bar will be described as the material to be precisely derived. Subsequently, it is determined whether to modify the data of the raw material (S42). If the raw material is required to be modified, the raw material is modified (70) and stored in raw material iron (S71). If the raw material is not required to be modified, it is determined whether there is a precision derivation target (S43). If there is a precision derivation target, the rebar is selected, that is, the selected rebar is read from the rebar list, and the minimum loss is designated as -1 (minus 1) (S44). Subsequently, it is determined whether there is no further raw material data (S45), and if there is raw material data, data such as diameter or length of the raw material is stored in raw material iron (S46). Subsequently, it is determined whether the diameter of the rebar is the same as the diameter of the raw material (S47). If the diameters are the same, it is determined whether the length of the bar to be drawn is smaller than the length of the raw material (S48). If the length of the raw material is smaller than the length of the scaled out reinforcing bar, the process returns to the step of determining whether there is no more data of the raw material (S45). The remainder divided by the length is determined as a loss (S49). Subsequently, it is determined whether the minimum loss is -1 (minus 1) (S50). If the minimum loss is -1, the length of the raw material is defined as the minimum loss length, and the loss defined above is defined as the minimum loss (S51). The process returns to step S45 to determine whether there is more. If the minimum loss is not -1, it is determined whether the minimum loss is greater than the loss (S52). If the loss is greater than the minimum loss, the process returns to the step of determining whether there is no data of the raw material (S45). The length of the raw material is defined as the minimum loss length, the loss at that time is defined as the minimum loss (S51), and the process returns to the step of determining whether there are no more raw materials (S45). If the minimum loss is greater than the loss from the step of determining whether there are no more materials of the raw material (S45), the step of defining the length of the raw material as the minimum loss length and defining the loss at that time as the minimum loss (S51) is repeated. From which raw material the reinforcing bar is to be processed, the least loss of the raw material is calculated. And if there are no more raw materials, the minimum loss length is defined as the precision length (S53). Subsequently, the minimum loss length is divided by the length of the reinforcing bar and the share is defined as the quantity produced per piece (S54), and the production quantity of the reinforcing bar is divided by the quantity per piece to determine whether the remainder is 0 (zero) (S55). If the remainder is 0, the required quantity divided by the production quantity of the reinforcing bar divided by the production quantity is defined as the required quantity (S56), and if the production quantity of the reinforcing steel is divided by the production quantity per unit, the remaining quantity is not 0. The quantity obtained by dividing the production quantity by the production quantity per piece is defined as the required quantity by adding 1 to the required quantity (S57). The total loss length is then the value obtained by multiplying the precision length and the required quantity by the product of the length of the reinforcing bar and the manufacturing quantity (S58), and the total loss weight is obtained by multiplying the total loss length by the unit weight of the reinforcing bar. It becomes a value (S59). The total loss length and the total loss weight are stored in the precision calculation data (S60). Subsequently, the process returns to the step of determining whether there is a precision derivation target (S43), and if there is no further precision derivation target, the output of precision deduction data stored in the precision derivation file (S61) ends. 8 illustrates an example of data output in the above-described precision drawing step.

As described above, if you input a building drawing with coded text including the property information of reinforcing bars and designate a desired area, the list of reinforcing bars included in the area is output and the bars to be processed based on the output data. It is easy to determine which of the raw materials entered into the factory is the least loss of raw materials, and the reinforcing bar list can be returned or shipped, goods received, materials entered, or billed for the materials shipped. It can also be useful for materials.

Another embodiment of the present invention is an architectural drawing analysis and processing apparatus using a computer including a memory unit and a control unit, wherein the memory unit stores a program for controlling the control unit, and the control unit is connected to the memory unit and is connected to the program. Operation to perform the above-described steps. Each process is the same as described above, so a detailed description thereof will be omitted.

On the other hand, the architectural drawing analysis and processing method using a computer including each of the three steps of an embodiment of the present invention described above can be read by a computer that records a program for executing each step as in another embodiment of the present invention. Of course, it can be realized as a recording medium.

Which raw materials should be processed from among the raw materials that have the raw materials to reduce the loss of raw materials, thereby reducing the waste of raw materials.
