Description

  The present invention relates to a construction drawing drawing system for arranging construction drawings so that reinforcing bars do not interfere with each other.

Conventionally, the structural drawing data A and the equipment drawing data B for the same construction site are superimposed on each other in the same coordinate system so that the member interference between the structural member and the equipment member can be displayed in an easy-to-match state. When the mutual interference between the structural member shown in the structural drawing data A and the equipment member shown in the equipment drawing data B is collated, it is displayed from the drawing data of the equipment member and the structural member. There is known a member interference matching system that sorts display members to be displayed and non-display members not to be displayed, three-dimensionally displays the sorted display members, and checks interference between the structural member and the equipment member (for example, a patent) Reference 1).

  By the way, the base plate and a certain amount of reinforcing bars are used in the concrete of the foundation of the building. However, when designing the building, the reinforcing bars should be arranged so that there is no interference between the reinforcing bars and between the reinforcing bar and the base plate. The position is rarely considered, and only the diameter and quantity of reinforcing bars to be used are generally specified. Therefore, at the time of creating the construction drawing, the arrangement position of the reinforcing bars is examined and the construction drawing is drawn so that the interference between the reinforcing bars and the interference between the reinforcing bars and the base plate does not occur. However, drawing construction drawings around the base plate of the foundation and reinforcing bars in columns and beams without a base plate requires advanced knowledge, and it takes time to review the arrangement and troublesome drawing creation and correction. Moreover, since it takes time and effort to take the consistency of the drawing with the plan view and the cross-sectional view, there is a problem that it takes a lot of time.

  The present invention has been made in view of such circumstances, and the relocation of the reinforcing bars is automatically performed so that the rebars do not interfere, and the construction drawing based on the result of the relocation can be easily drawn. An object is to provide a drawing system.

  The present invention is based on condition data storage means in which information on construction conditions and arrangement position movement conditions is stored, reinforcing bar information input means for inputting information on reinforcing bars to be used, and reinforcing bar information input by the reinforcing bar information input means. The initial arrangement processing means for determining the initial arrangement of the reinforcing bars to be used and the interference of the reinforcing bars arranged by the initial arrangement processing means are detected so as to satisfy the construction conditions stored in the condition data storage means. An interference detection / avoidance processing means for moving the arrangement position of the reinforcing bar so as to satisfy the arrangement position movement condition stored in the condition data storage means and preventing the interfering reinforcing bar from interfering, and the interference detection / avoidance And display means for displaying the final placement position information including the reinforcing bar whose placement position has been moved by the processing means.

  The present invention is further characterized by further comprising an arrangement position correction means for inputting arrangement position information for correcting the reinforcing bars rearranged by the interference detection / avoidance processing means.

  According to the present invention, the reinforcing bars are automatically rearranged so that the reinforcing bars do not interfere, and the construction drawing based on the rearranged result is drawn. In addition, the time required for drawing consistency can be greatly shortened, and the construction drawing can be drawn without a high level of knowledge at the time of drawing creation.

  Hereinafter, a construction drawing system according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the embodiment. In this figure, reference numeral 1 denotes a construction drawing drawing system which is arranged so that the reinforcing bars around the base plate do not interfere with each other and draws construction drawings, and is constituted by a personal computer or the like. Reference numeral 2 denotes an input unit composed of a keyboard, a mouse, and the like. Reference numeral 3 denotes a display unit composed of a display device. Reference numeral 4 denotes a condition data storage unit that stores information on conditions to be applied when rebar interference is avoided. Reference numeral 5 denotes a construction drawing data storage unit that stores construction drawing data generated by the construction drawing drawing system 1. Reference numeral 6 denotes a printing unit configured by a printer or the like that prints a construction drawing based on the construction drawing data generated by the construction drawing drawing system 1. Reference numeral 7 denotes a design system constituted by a CAD system or the like that supports the design of a building. Reference numeral 8 denotes a frame information storage unit that stores frame information of a building designed by the design system 7. The design data storage unit 8 includes design information related to reinforcing bars around the base plate.

  Reference numeral 11 denotes an information input unit that reads the data input from the input unit 2 and the chassis information stored in the design data storage unit 8 and holds the information inside. Reference numeral 12 denotes an initial arrangement processing unit that performs initial arrangement of reinforcing bars based on the case information input from the input unit 2 or the case information read from the case information storage unit 8. Reference numeral 13 detects whether the reinforcing bars arranged by the initial placement processing unit 12 do not interfere with each other, and satisfies the conditions stored in the condition data storage unit 4 in order to avoid interference of the detected reinforcing bars. The interference detection / avoidance processing unit executes the interference avoidance processing as described above and performs rearrangement so that the reinforcing bars do not interfere with each other. Reference numeral 14 denotes a drawing processing unit that performs drawing processing of the construction drawing of the reinforcing bars that have been rearranged so that the reinforcing bars do not interfere with each other, and outputs the drawing result to the construction drawing data storage unit 5 or the printing unit 6.

  Here, the reinforcing bars arranged around the base plate will be described with reference to FIG. 12 shows a reinforcing bar 26 in a column extending in the Z-axis direction (height direction) around the base plate 21, an upper bar 22 and a lower bar 23 extending in the X-axis direction, and an upper beam extending in the Y-axis direction. It is a perspective view which shows the state which has arrange | positioned the line | wire 24 and the lower line | wire 25. FIG. In the design stage, only the arrangement position of the base plate 21 to be used, the size of the column, the size of the two beams, the number of reinforcing bars used in the column and the beam, and the like are only specified. For this reason, for example, the upper bar 22 of the X-axis beam and the upper bar 24 of the Y-axis beam need to be arranged with different heights. Further, it is necessary to consider the position of each reinforcing bar so that the upper bar 22 of the beam and the column reinforcing bar 26 do not interfere with each other. Furthermore, it is necessary to consider the arrangement of the upper bar 22 so that the anchor bolt of the base plate arranged in the column and the upper bar 22 of the beam do not interfere with each other. In the following description, an example of avoiding rebar interference in a column using the base plate 21 will be described, but the interference avoidance processing according to the present invention can also be applied to avoid interference of a rebar in a column without a base plate or a beam. It is. The example shown in FIG. 12 shows an example in which the beam and the column are joined at a right angle. However, the present invention can be applied to a beam having an arbitrary angle, and the rebar interval is automatically calculated. And have a function of spacing.

  Next, the operation of the construction drawing system 1 shown in FIG. 1 will be described with reference to FIGS. FIG. 2 is a flowchart showing the operation of the construction drawing system 1 shown in FIG. FIG. 3 is a flowchart showing the detailed operation of step S9 (level interference avoidance processing) shown in FIG. FIG. 4 is a flowchart showing the detailed operation of step S10 (plane interference avoidance processing) shown in FIG.

  First, when the operator operates the input unit 2 to start the construction drawing system 1, the information input unit 11 displays a function selection menu screen on the display unit 3. Here, the operator operates the input unit 2 to select any one of “condition setting”, “file read”, and “to input” (step S1). When the operator selects “condition setting”, the information input unit 11 displays a condition setting screen on the display unit 3. Here, the operator sets conditions (step S2). FIG. 5 shows an example of the condition setting screen. The conditions to be set here are “interference avoidance priority”, “concrete construction cover thickness (minimum cover thickness + 10 mm)”, and “minimum drilling dimension of orthogonal reinforcing bars”. The priority order for avoiding interference is a priority order that means that when a rebar interference occurs, the current position is not given priority for movement.

  The example shown in FIG. 5 shows a state in which priorities other than the four corners of the column main bars other than the anchor bolts, the four corners of the column main bars, the four corners of the beam main bars, and the four corners of the beam main bars are set. Therefore, when interference occurs, it means that the anchor bolt is not moved, but is moved from other than the four corners of the column main bars having a low priority and rearranged. When this priority order is changed and set, the "up" or "down" button is operated to change the priority. For the minimum cover thickness of concrete, the value of the concrete cover thickness is input and set for “column”, “upper part of beam”, “side of beam”, and “lower part of beam”. Also, enter a value for the minimum perforated dimension of the reinforcing bars. As these condition values, default values (default values) are set in advance as shown in FIG. 5, and values need only be input when they are changed. The condition value input and set here is stored in the condition data storage unit 4. When the operator presses the “OK” button, the screen returns to the function selection menu screen.

  When the operator selects “read file” on the function selection menu screen, the information input unit 11 displays a file selection screen on the display unit 3 and issues an instruction to specify a file in which the chassis information is stored. On the other hand, the worker designates a file in which the chassis information is stored. Then, the information input unit 11 reads the frame information from the designated file (here, the frame information storage unit 8) (step S3). When reading of the chassis information is completed, the process proceeds to step S4. Further, when “to input” is selected from the function selection menu screen, the process proceeds to step S4.

  Next, the information input unit 11 displays a core / level information input screen on the display unit 3. Here, the operator operates the input unit 2 to set the X core number, the Y core number, the 1FL height (ground floor height) from GL (ground surface height), The height from GL (ground surface height) to the lower end of the base plate is input (step S4). FIG. 6 shows an example of the core / level information input screen. At this time, if the value to be input here is included in the read chassis information, the value is already input as an initial value. The information input unit 11 holds each value input here. When the operator presses the “Next” button, the process proceeds to the next.

  Next, the information input unit 11 displays a basic information input screen on the display unit 3. Here, the operator operates the input unit 2 to input the size of the foundation, the position of the foundation, the reinforcing bars to be used, and the number of pieces to be used (step S5). FIG. 7 shows an example of a basic information input screen. At this time, if the value to be input here is included in the read chassis information, the value is already input as an initial value. The information input unit 11 holds each value input here. When the operator presses the “Next” button, the process proceeds to the next.

  Next, the information input unit 11 displays a column information input screen on the display unit 3. Here, the operator operates the input unit 2 to input the size of the column, the position of the column, the reinforcing bars used and the number used, and the model number of the base plate used (step S6). FIG. 8 shows an example of a column information input screen. At this time, if the value to be input here is included in the read chassis information, the value is already input as an initial value. The information input unit 11 holds each value input here. When the operator presses the “Next” button, the process proceeds to the next.

  Next, the information input unit 11 displays a beam information input screen on the display unit 3. Here, the operator operates the input unit 2 and inputs the size of the beam, the position of the beam, the reinforcing bars to be used, and the number of bars to be used (step S7). FIG. 9 shows an example of a beam information input screen. At this time, if the value to be input here is included in the read chassis information, the value is already input as an initial value. The information input unit 11 holds each value input here. When the operator presses the “Next” button, the process proceeds to the next.

  Next, when the information input is completed, the information input unit 11 delivers each value held therein to the initial arrangement processing unit 12. In response to this, the initial placement processing unit 12 creates a reinforcing bar object based on the passed values, and uses the reinforcing bar object to reinforce the reinforcing bar in the foundation, the reinforcing bar and base plate in the column, and the beam in the beam. The initial arrangement of the reinforcing bars is performed (step S8). The reinforcing bar object is graphic information specified by the coordinate value of the core of the reinforcing bar and the information on the diameter of the reinforcing bar. In this initial arrangement process, the position of the reinforcing bar is determined with reference to the value of the minimum cover thickness of the concrete stored in the condition data storage unit 4. At this time, the initial placement processing unit 12 determines the initial placement position so that the specified reinforcing bars are placed at equal intervals so as to satisfy the minimum cover thickness. When the determination of the initial placement position is completed, the initial placement processing unit 12 delivers the initial placement position information of the reinforcing bars in the foundation, the reinforcing bars and base plate in the column, and the reinforcing bars in the beam to the interference detection / avoidance processing unit 13.

  Next, the interference detection / avoidance processing unit 13 detects interference of reinforcing bars in the height (level) direction in the initial arrangement state, and performs avoidance processing if there is interference of reinforcing bars (step S9). Here, the processing operation of step S9 will be described with reference to FIG. First, the interference detection / avoidance processing unit 13 specifies two beams to be compared and acquires information on these beams (step S21). Then, the interference detection / avoidance processing unit 13 acquires information on the reinforcing bars of one beam (step S22) and acquires information on the reinforcing bars of the other beam (step S23).

  Next, the interference detection / avoidance processor 13 determines whether or not the Z difference between the two reinforcing bars is greater than or equal to an allowable value (step S24). The Z difference here is the difference in height between the two reinforcing bars to be compared. The allowable value is a value obtained by adding the diameter of one reinforcing bar and the diameter of the other reinforcing bar and dividing by two.

  As a result of this determination, if the Z difference is less than the allowable value, the interference detection / avoidance processing unit 13 determines whether or not the reinforcing bar in the X direction or the Y direction is to be arranged on the upper side (step S28). In this determination, for example, rule information such as “place the X direction on the upper side” and “place the same direction as the direction of the beam (eg, the Y direction) on the upper side” is stored in the condition data storage unit 4 in advance. The determination is made with reference to this information. As a result of this determination, if the X direction is to be arranged on the upper side, it is determined whether the target reinforcing bar is the upper or lower reinforcing bar (step S29). As a result of this determination, if it is an upper bar, the rebar of the beam in the Y direction is rearranged so as to be lowered by (allowable value−Z difference) (step S30). On the other hand, if it is a lower bar, the rebar of the beam in the X direction is rearranged so as to increase by (allowable value−Z difference) (step S31).

  Next, as a result of the determination in step S28, if the Y direction is arranged on the upper side, it is determined whether the target reinforcing bar is the upper reinforcing bar or the lower reinforcing bar (step S32). As a result of this determination, if it is an upper bar, the rebar of the beam in the X direction is rearranged so as to be lowered by (allowable value−Z difference) (step S33). On the other hand, if it is a lower bar, the rebar of the beam in the Y direction is rearranged so as to increase by (allowable value−Z difference) (step S34).

  Next, the interference detection / avoidance processor 13 determines whether or not all the reinforcing bars of the other beam have been compared (step S25). If not all the reinforcing bars have been compared, the process returns to step S23, and the same The process is performed, and the process is repeated until the comparison is completed for all the other reinforcing bars.

  Next, the interference detection / avoidance processing unit 13 determines whether or not all the reinforcing bars of one beam have been compared (step S26). If not all the reinforcing bars have been compared, the process returns to step S22, and the same The process is performed, and the process is repeated until the comparison is completed for all the reinforcing bars.

  Next, the interference detection / avoidance processing unit 13 determines whether or not all beams have been compared (step S27). If all beams have not been compared, the process returns to step S21 to perform the same processing. Repeat the process until all beams have been compared.

  By this process, it is determined whether or not all the reinforcing bars of all the beams are interfering with each other. If there is an interference, one of the interfering reinforcing bars is moved to the upper side or the lower side and rearranged. It will be.

  Returning to FIG. 2, the interference detection / avoidance processor 13 detects the interference of the planar interference rebar, and performs the avoidance process if there is interference of the rebar (step S <b> 10). Here, the processing operation of step S10 will be described with reference to FIG. First, the interference detection / avoidance processing unit 13 specifies a beam to be compared and acquires information on the beam (step S41). Then, the interference detection / avoidance processing unit 13 acquires information about the reinforcing bars of the beam (step S42) and also acquires information about the reinforcing bars of the column (step S43).

  Next, the interference detection / avoidance processor 13 determines whether or not the X (Y) difference between the two reinforcing bars is greater than or equal to an allowable value (step S44). The X (Y) difference here is the difference between the X coordinates of the beam reinforcement and the column reinforcement in the case of the X-axis beam, and in the case of the Y-axis beam, the difference between the beam reinforcement and the column reinforcement. This is the difference in Y coordinates. The allowable value is a value obtained by adding the diameter of one reinforcing bar and the diameter of the other reinforcing bar and dividing by two.

  As a result of this determination, if the X (Y) difference is less than the allowable value, the interference detection / avoidance processing unit 13 determines which of the priorities stored in the condition data storage unit 4 is set higher. (Step S49). If the beam priority is high as a result of the determination, it is determined whether or not the separation distance is equal to or greater than a specified value when the column reinforcing bar is moved (step S50). This specified value is a value in which the distance from the core of the reinforcing bar is 2.5 times the diameter of the reinforcing bar. As a result of this determination, if the separation distance is equal to or greater than the specified value, the interference detection / avoidance processing unit 13 moves the column reinforcement by (allowable value−X (Y) difference) (step S51). On the other hand, when the separation distance is not equal to or greater than the specified value, the interference detection / avoidance processing unit 13 moves the rebar of the beam by (allowable value−X (Y) difference) (step S53).

  Next, as a result of the determination in step S49, if the priority of the column is high, it is determined whether or not the separation distance is equal to or greater than a specified value when the rebar of the beam is moved (step S52). As a result of this determination, if the separation distance is equal to or greater than the specified value, the interference detection / avoidance processing unit 13 moves the rebar of the beam by (allowable value−X (Y) difference) (step S53), and the separation distance is specified. If not, the interference detection / avoidance processor 13 moves the column reinforcement by (allowable value−X (Y) difference) (step S51).

  Next, the interference detection / avoidance processing unit 13 determines whether or not all the reinforcing bars of the column have been compared (step S45). If not all the reinforcing bars have been compared, the process returns to step S43 and the same processing is performed. And repeat the process until all the reinforcing bars in the column have been compared.

  Next, the interference detection / avoidance processor 13 determines whether or not the X (Y) difference between the beam reinforcing bar and the anchor bolt is greater than or equal to an allowable value (step S46). If the result of this determination is that it is not greater than or equal to the allowable value, the interference detection / avoidance processor 13 moves the rebar of the beam by (allowable value−X (Y) difference) (step S54). On the other hand, if it exceeds the allowable value, the movement is not performed.

  Next, the interference detection / avoidance processing unit 13 determines whether or not all the reinforcing bars of the beam have been compared (step S47). If all the reinforcing bars have not been compared, the process returns to step S42 and the same processing is performed. And repeat the process until all the reinforcing bars of the beam have been compared.

  Next, the interference detection / avoidance processing unit 13 determines whether or not all beams have been compared (step S48). If not all the beams have been compared, the process returns to step S41, and the same processing is performed. Repeat the process until all beams have been compared.

  By this process, it is determined whether or not all the reinforcing bars of all the beams are interfering with the reinforcing bars of the column. If there is an interference, one of the interfering reinforcing bars is moved and rearranged. Become.

  Returning to FIG. 2, the interference detection / avoidance processing unit 13 displays the result of the interference avoidance processing on the display unit 3. FIG. 10 shows an example of a screen for confirming the result of the interference avoidance process. On this screen, a diagram showing the arrangement status of the reinforcing bars in each beam and a field for inputting positional information for manually fine-tuning the arrangement of the reinforcing bars are displayed. When the operator directly inputs a value in this input field, it is possible to make corrections such as fine adjustment of the relocated reinforcing bars. Then, the operator proceeds to the next step by pressing the “Next” button.

  Next, the interference detection / avoidance processing unit 13 passes the information on the repositioned reinforcing bars to the drawing processing unit 14. In response to this, the drawing processing unit 14 generates construction drawing data based on the position information of the relocated reinforcing bars, and stores it in the construction drawing data storage unit 5. In addition, the drawing processing unit 14 outputs the generated construction drawing data to the printing unit 6 and prints the construction drawing. In FIG. 11, an example of the construction drawing output by the drawing process part 14 is shown. The actual arrangement of reinforcing bars around the base plate is as shown in FIG. 12, but the example shown in FIG. 11 shows an example in which only the reinforcing bars to be processed are output.

  Note that, after the reinforcing bar interference avoiding process by the interference detection / avoidance processing unit 13, the section coefficient of the relocated reinforcing bars is recalculated, and a process of confirming whether there is a problem in the structural calculation is executed. Good.

  Further, in the above description, an example has been described in which, if there is interference by comparison one by one, the reinforcing bars in which the interference is generated are moved one by one, but is there interference only for the reinforcing bars that represent the row of reinforcing bars? It may be determined whether or not, and if there is interference, all the reinforcing bars constituting the target reinforcing bar row are moved simultaneously, and the processing may be simplified to increase the speed.

  In this way, the rebars are automatically rearranged so that they do not interfere with each other, and construction drawings based on the result of the rearrangement are drawn. It is possible to drastically reduce the time required to achieve consistency, and it is possible to draw a construction drawing without a high level of knowledge at the time of drawing creation.
