[0022]
[Problems to be solved by the invention]
According to the conventional pipe design and drawing method, the pipe diameter of each part of the pipe is calculated by a predetermined method, and then the pipes and members are drawn based on the pipe diameter. Therefore, there has been a problem that the design and drawing of the piping can only be performed by engineers having specialized knowledge.
[0023]
In addition, since the drawing was created by hand, there was a problem that the drawing could not be created without the help of a draftsman having specialized knowledge.
[0024]
In addition, there is a problem that it takes time to design because a specialized engineer manually calculates the pipe diameter and a specialized drafting person performs drafting.
[0025]
Further, when there is a design change, there is a problem that the drawing of the piping has to be rewritten.
[0026]
The present invention has been made in view of such a situation, and can easily, in a short time, determine the pipe diameter and draw the pipe without any specialized knowledge. It is.

Is determined by FIG. 8 shows a drainage load unit corresponding to each sanitary device. FIG. 9 shows the (diameter of pipe) corresponding to the drainage load unit shown in FIG.
[0054]
For example, as shown in FIG. 10, the routes of the branch pipes of the toilets 22 and 23 and the basin 24 are respectively arranged in this order from the cleaning port 28 which is the upstream end of the channel 21 of the drain horizontal branch pipe. 8, the drainage load units in the branch pipe routes 25, 26, and 27 are 4, 4, and 1, respectively, from FIG. At this time, the pipe diameters corresponding to the drainage load units are 50A, 50A and 30A, respectively, as shown in FIG.
[0055]
Next, the computing unit 5 computes a drainage load unit of the path 21a of the horizontal drainage branch pipe between the junctions P1 and P2. In this case, since only the branch pipe route 25 from the toilet 22 joins upstream of the branch pipe route 21a, the drainage load unit of the branch pipe route 21a is four. Therefore, from FIG. 9, the diameter of the drain pipe to be piped to the branch pipe path 21a is determined to be 50A corresponding to the drain load unit 4.
[0056]
In addition, a branch pipe path 25 and a branch pipe path 26 merge upstream of the drain horizontal branch pipe path 21b between the junctions P2 and P3. Therefore, the drainage load units of the respective branch pipes are added in order from the upstream side by the arithmetic unit 5, and the total value is set as the drainage load unit of the branch pipe path 21b. In this case, since the drainage load units of the branch pipe route 25 and the branch pipe route 26 are respectively 4, the total value 8 obtained by adding them is the drainage load unit of the branch pipe route 21b. Therefore, from FIG. 9, the diameter of the drain pipe to be piped to the branch pipe path 21b is determined to be 65A corresponding to the drainage load unit 8.
[0057]
Further, since the branch pipe routes 25 to 27 join the upstream of the drain horizontal branch pipe route 21c disposed downstream of the junction P3, the arithmetic unit 5 causes the branch pipe routes 25 to 27 The drainage load units are summed, and the total value is used as the drainage load unit of the branch pipe path 21c. In this case, the drainage load unit of the branch pipe route 25 and the branch pipe route 26 is 4 and the drainage load unit of the branch pipe route 27 is 1, so that the total value 9 obtained by adding them is the branch value. The unit is a drainage load unit of the pipe path 21c. Accordingly, from FIG. 9, the diameter of the drain pipe to be piped to the branch pipe path 21c is set to 65A corresponding to the drain load unit 9.
[0058]
Next, the processing unit 4 determines whether there is a path in which a member (a drain pipe or a joint) having the diameter determined by the calculation unit 5 cannot be generated, or whether there is a path in which the members overlap each other. If there is a path on which the member having the caliber determined by the above cannot be generated or there is a path on which the members overlap each other, an error is displayed on the screen of the display unit 1.
[0059]
Next, the process proceeds to step S46, where the processing unit 4 generates a pipe member as shown in FIG. That is, the drainage pipes 111a to 111i having the diameter determined in step S45 and the corresponding joints 11a and 11b are displayed at corresponding positions on the screen.
[0060]
For example, when each sanitary device is arranged as shown in FIG. 10, first, at the confluence points P1 to P3 in FIG. 10, the route of the drainage pipe to be generated in each route is calculated at step S45. Is read from the storage unit 3 by the processing unit 4.
[0061]
For example, a joint 31 having a shape as shown in FIG. 12 is formed at the junction P2 such that the three core wires 31a to 31c and the paths 21a, 21b and 26 of the branch pipes overlap at the connection points 31d to 31f, respectively. Placed in
[0062]
Next, the drainage pipe (not shown) having the diameter determined in step S45 is generated by the processing unit 4 between the connection points connecting the sanitary appliances and the joints or between the connection points connecting the joints. . For example, when the distance between the sanitary appliances is changed, these drainage pipes can be expanded and contracted in response to the change.
[0063]
At this time, the processing unit 4 displays an error on the screen of the display unit 1 when there is a portion where the member having the diameter determined in step S45 cannot be generated or there is a portion where the members overlap each other.
[0064]
When the generation and display of the drainpipe and the joint are completed, the processing section 4 drains the branch pipe route 25 from the sanitary equipment (the toilet 22 in this case) disposed at the uppermost stream as shown in FIG. Pipes 42 and 43 and elbows 41 having a diameter similar to the diameter of the drainage pipe at the merging point P1 are provided at a predetermined distance from the toilet 22 on an extension of the point P1 merging with the path 21 of the horizontal branch pipe. , And the cleaning port 28 are arranged and displayed on the display unit 1, and the process is terminated.
[0065]
Next, the operation of the water supply pipe design display device to which the piping design device of the present invention is applied will be described with reference to the flowchart of FIG. The configuration of the water supply pipe design display device basically has the same structure as that of the drain pipe design display device shown in FIG. First, in step S51, a piping mode is set. In this case, set the mode of the water supply pipe. Next, the process proceeds to step S52.
[0066]
In step S52, for example, a sizing setting screen as shown in FIG. 4 is displayed on the display unit 1, and a predetermined column (a common column in the case of a water supply pipe) of the screen includes a mouse, a tablet, or a keyboard. The sizing setting is performed by operating the input setting unit 2 to input or select a predetermined item. That is, first, the water supply equipment withdrawal distance a is set. As described later, when a water supply device is arranged and connected to the main pipe at a predetermined distance from the arranged water supply device, the distance a needs to be set.
[0067]
Next, selection of the drawing direction, that is, selection of whether the branch pipe connecting the water supply equipment and the main pipe is connected to the main pipe through the right side of the water supply equipment or connected to the main pipe through the left side of the water supply equipment. I do. Next, the drawer distance b of the water supply equipment is set. Further, the distance c between the reducer 4a and an adjacent component when the reducer 4a having a different size between the inlet and the outlet is arranged is input. Next, a horizontal distance d between the entrance of the 45-degree elbow and the exit when the 45-degree elbow is arranged is input.
[0068]
Next, the process proceeds to step S53, where the water supply equipment is arranged. That is, as shown in FIG. 15, the water supply devices 15a and 15b are arranged at predetermined positions on the screen of the display unit 1 by the input setting unit 2 composed of a mouse or a tablet. At this time, only one water supply device can be arranged, or a plurality of water supply devices can be arranged.
[0069]
Next, the process proceeds to step S54, where two points on the screen of the display unit 1 are designated by the input setting unit 2 composed of, for example, a mouse or a tablet, as shown in FIG. A route 16c is created and displayed. When the main pipe path 16c is displayed on the screen, the branch pipe path between the water supply equipment and the main pipe is set based on the water supply equipment connection draw-out distances a and b and the draw-out direction set on the sizing screen shown in FIG. 16a and 16b are determined by the processing unit 4, and are displayed on the screen.
[0070]
Further, when the processing unit 4 determines that an unnecessary route is included in the route 16c of the main pipe set by the input setting unit 2, the processing unit 4 displays a screen for inquiring whether or not the route should be deleted. 1 is displayed. The user can delete the route by designating the route to be deleted on this screen.
[0071]
Next, proceeding to step S55, the user designates the downstream side or the upstream side using the four-button cursor or the mouse of the tablet, and specifies the direction of the flow. Next, the diameter of the water supply pipe to be piped to the path set by the input setting unit 2 and the path determined by the processing unit 4 is calculated by the calculation unit 5, for example, as shown in FIG. Characters representing the caliber calculated by the unit 5 are displayed on the right side of the corresponding route.
[0072]
FIG. 18 is a diagram showing a procedure in which the processing unit 4 determines the pipe diameter of the water supply pipe. First, in step S61, the processing unit 4 causes the input setting unit 2 to store a relationship between each water supply device and the diameter of a connection pipe connected to each water supply device, which is stored in advance in the storage unit 3 (see FIG. Based on the information corresponding to 19), the diameter of the connection pipe of each device (water supply device) is set.
[0073]
For example, as shown in FIG. 20, when the handwashers 51, 52, the urinal 53, and the urinal 54 are arranged in this order, the connection pipe diameter of the handwashers 51, 52, the urinal 53, and the urinal 54 is set. Are 13, 13, 13, and 25 (in this case, wash valves) from the table shown in FIG. Therefore, these connection pipe diameters are set by the processing unit 4.
[0074]
Next, proceeding to step S62, the processing unit 4 uses the input setting unit 2 to store the connection pipe diameter of each water supply device and the equivalent number when converted to the pipe diameter 13, which are stored in the storage unit 3 in advance. The equivalent number of each device is determined from the information corresponding to the equivalence table (FIG. 21) showing the relationship with. In this case, as shown in FIG. 22, the even number of the urinals 54 is 5.6, the even number of the urinals 53 is 3.1, and the even number of the handwashers 51 and 52 is 1 respectively. It is.
[0075]
Next, the process proceeds to step S63, in which the cumulative total of the equal number in each section A, B, or C is calculated. In the section A, the even number of the toilets 54 alone is set to 5.6, and in the section B, the total number 8.7 of the equal numbers of the toilets 54 and the urinals 53 is calculated. Is the total number of the uniform number 5.6 of the urinal 54, the uniform number 3.1 of the urinal 53, the uniform number 1 of the handwasher 51, and the uniform number 1 of the handwasher 52. And general equipment). According to the table shown in FIG. 23, the urinal 53 and the handwashers 51 and 52 are general appliances, and the number of those appliances is 3, so the simultaneous use rate is 70%.
[0076]
Next, the process proceeds to step S64, where the arithmetic unit 5 multiplies the total of the equal numbers in each section by the simultaneous usage rate shown in FIG. 23 as shown in FIG. Is calculated.
[0077]
In this case, the even number considering the simultaneous usage rate in the section A is 5.6, and the even number considering the simultaneous usage rate in the section B is 8.7. In addition, the equivalent number considering the simultaneous usage rate of the section C is 5.6 obtained by multiplying the equal number of the urinals 54 by the simultaneous usage rate 1.0, and the equal number 3.1 of the urinal 53. , The value 5.1 obtained by adding the equal number 1 of the hand-washing machine 51 and the equal number 1 of the hand-washing machine 52 to the value 3 obtained by multiplying the simultaneous use rate 0.7 of these three devices by 3. .57 is obtained as a value 9.17.
[0078]
Next, in step S65, the processing unit 4 uses the information corresponding to the spreadsheet (FIG. 21) stored in the storage unit 3 to calculate the value of the uniform number in consideration of the simultaneous usage rate calculated in each of the sections A to C. Is determined. In this case, the equivalent number in consideration of the simultaneous use rate in the section A is 5.6, and the diameter of the connection pipe corresponding thereto is set to 25 from the equivalent table shown in FIG. Further, the equivalent number in consideration of the simultaneous usage rate in the section B is 8.7, and the diameter of the connection pipe corresponding thereto is set to 30 from the equivalent table shown in FIG. Further, the equivalent number in consideration of the simultaneous use rate in the section C is 9.17, and the diameter of the connection pipe corresponding thereto is set to 30 from the equivalent table shown in FIG.
[0079]
In this way, the processing unit 4 can determine the diameter of the connection pipe in each section.
[0080]
Next, the processing unit 4 determines whether there is a path in which a member (water supply pipe or joint) having the diameter determined by the calculation unit 5 cannot be generated or a path in which the members overlap each other. If there is a path on which a member having the determined diameter cannot be generated or a path on which the members overlap, an error is displayed on the screen of the display unit 1.
[0081]
Next, the process proceeds to step S56 in the flowchart of FIG. 4, and as shown in FIG. 25, the processing unit 4 generates a pipe member. That is, the water supply pipes 251 a to 251 i having the diameter determined in step S <b> 55 and the corresponding joints 25 a to 25 f having a shape as shown in FIG. 26 are displayed at the corresponding positions on the screen of the display unit 1. Is done.
[0082]
As shown in FIG. 20, when each appliance is arranged and the path of the pipe is set, first, at each of the confluence points P11 to P12 in FIG. 20, it is generated in each path calculated in step S55. A joint having a diameter corresponding to the path of the water supply pipe to be read is read from the storage unit 3 by the processing unit 4.
[0083]
For example, at the junction P11, a joint 61 having a shape as shown in FIG. 26 is formed such that the three core wires 61a to 61c and the branch pipe paths 55a, 55b and 57 overlap at the connection points 61d to 61f, respectively. Be placed.
[0084]
Next, the processing unit 4 generates a water supply pipe (not shown) having the diameter determined in step S55 between the connection points of the water supply devices and the joints or between the connection points of the joints. These water supply pipes are made extendable and contractible in response to, for example, a change in the distance between the water supply devices.
[0085]
At this time, when there is a portion where the member having the diameter determined in step S55 cannot be generated or there is a portion where the members overlap each other, the processing unit 4 displays an error on the screen of the display unit 1.
[0086]
In step S56, when the processing unit 4 displays a pipe member having a predetermined diameter on the display unit 1, the processing ends.
[0087]
Next, the operation of the ventilation pipe design display device to which the piping design device of the present invention is applied will be described with reference to the flowchart of FIG. The configuration of the ventilation pipe design display device basically has the same structure as that of the drain pipe design display device shown in FIG. First, in step S71, a piping mode is set. In this case, the mode of the ventilation pipe is set. Next, the process proceeds to step S72.
[0088]
In step S72, the design of the drainage pipe is displayed. The processing here is basically the same as the processing performed in the design display of the drainage pipe described with reference to FIG. 3, and thus the description thereof is omitted.
[0089]
Next, the process proceeds to step S73, where two points on the screen of the display unit 1 are designated by the input setting unit 2 composed of, for example, a mouse or a tablet, as shown in FIG. A route 28a is created and displayed.
[0090]
When the processing unit 4 determines that an unnecessary route is included in the route 28a of the main pipe set by the input setting unit 2, the processing unit 4 displays a screen for inquiring whether or not the route should be deleted. 1 is displayed. The user can delete the route by designating the route to be deleted on this screen.
[0091]
Next, proceeding to step S74, the caliber (pipe diameter) of the ventilation pipe to be piped in the path set by the input setting unit 2 is calculated by the calculating unit 5, for example, as shown in FIG. The character (in this case, 25A) representing the caliber calculated by 5 is displayed on the right side of the path of the corresponding vent pipe.
[0092]
Next, referring to the flowchart of FIG. 30, for example, drain pipes 31a to 31d are connected along a route as shown in FIG. 31, and further, each sanitary device is connected to a predetermined position of the drain pipes 31b to 31d. In this case, a method for determining the diameter of the ventilation pipes installed in these drain pipes will be described.
[0093]
In FIG. 31, three branch pipe paths 31b, 31c, and 31d are connected to the main pipe path 31a, and toilet bowls 71 to 74 and a cleaning sink 71 are connected to the branch pipe path 31b. I have. Further, basins 75 to 77 are connected to the branch pipe path 31c. Further, urinals 78 to 80 are connected to the branch pipe path 31d. In step S73, it is assumed that paths 31e to 31h and 31k of the ventilation pipe have been set.
[0094]
First, in step S81, the input setting unit 2 designates a device which the ventilation pipe to be installed in the ventilation pipe path shown in the ventilation pipes 31e to 31h and 31k serves. Normally, it is responsible for ventilation of equipment connected by one drainage pipe. Therefore, for example, the ventilation of the sanitary devices 71 to 74 is specified so that the ventilation pipe to be piped to the path 31e of the ventilation pipe is responsible. Also, the ventilation of the sanitary devices 75 to 77 is specified so that the ventilation pipe to be piped to the passage 31f of the ventilation pipe is responsible. Furthermore, the ventilation of the sanitary devices 78 to 80 is specified so that the ventilation pipe to be piped to the path 31g of the ventilation pipe is responsible.
[0095]
Next, proceeding to step S82, the total value of the number of drainage load units is determined. That is, the information corresponding to the table shown in FIG. 8 is stored in the storage unit 3 in advance, and the processing unit 4 stores the information of the sanitary device connected thereto for each path of the ventilation pipe from the storage unit. The drainage load units are read out and added by the calculation unit 5 to calculate the drainage load units for each path of the ventilation pipe. For example, the sum of the drainage load units in the ventilation pipe path 31e is calculated by adding the values of the drainage load units of the three toilet bowls to the value 8 and the drainage load unit of the cleaning sink to the value 2.5. Is obtained as 26.5 (= 8 × 3 + 2.5).
[0096]
The same calculation method can be applied to the ventilation pipe paths 31f to 31h and 31k. That is, the drainage load unit of the ventilation pipe 31f is set to the value 3, the drainage load unit of the ventilation pipe 31g is set to the value 12, and the drainage load unit of the ventilation pipe 31h is set to the drainage load in the ventilation pipe 31f and the ventilation pipe 31g. A value of 15 is obtained by adding the units.
[0097]
The drainage load unit of the ventilation pipe 31k is a value 41.5 obtained by adding the drainage load unit of the ventilation pipe 31e and the drainage load unit of the ventilation pipe 31h.
[0098]
Next, in step S83, if there is a junction of the ventilation pipes, the longer horizontal distance to the junction is calculated. For example, the horizontal length of the ventilation pipe 31h is a value obtained by adding the longer length of the ventilation pipe 31f and the ventilation pipe 31g to the length of the ventilation pipe 31h, ie, 7.5. Similarly, the horizontal length of the ventilation pipe 31k is a value 13 obtained by adding the length of the ventilation pipe 31e having the longest length to the junction.
[0099]
Next, in steps S84 to S85, the pipe diameter of each ventilation pipe is calculated. The length of the ventilation pipe 31e in the horizontal direction (maximum allowable laterally running pipe length) is 10 meters. Therefore, in the table shown in FIG. 107, the drainage load unit is 26.5 or more, and the horizontal length is Is 10 meters or more, and the pipe diameter of the ventilation pipe 31e is 65A. Similarly, since the horizontal length of the ventilation pipe 31f is 3.5 meters in the drainage load unit of the ventilation pipe 31f, the drainage load unit is 3 or more in the table shown in FIG. Corresponds to the case where the length is 3.5 meters or more, and the pipe diameter of the ventilation pipe 31f is set to 40A.
[0100]
Similarly, since the horizontal length of the ventilation pipe 31g is 3.2 meters, in the table shown in FIG. 107, the drainage load unit is 12 or more and the horizontal length is 3. This corresponds to the case of 2 meters or more, and the pipe diameter of the ventilation pipe is 40A. Similarly, the drainage load unit of the ventilation pipe 31h is, as described above, the horizontal length of the ventilation pipe 31h of 4 meters and the horizontal length of the ventilation pipe 31f and the ventilation pipe 31g joining the ventilation pipe 31h. Since the value obtained by adding the longer value (in this case, the length of the ventilation pipe 31f is 3.5 meters) is 7.5 meters, the drainage load unit is 15 or more in the table of FIG. This corresponds to a case where the length in the direction is 7.5 meters or more, and the pipe diameter of the ventilation pipe 31h is set to 50A.
[0101]
Similarly, the drainage load unit of the ventilation pipe 31k is, as described above, the horizontal length of the ventilation pipe 31k and the longest distance in the horizontal direction among the ventilation pipes that join the ventilation pipe 31k. That is, since the value obtained by adding the horizontal length of 10 meters of the ventilation pipe 31e is 13 meters, the drainage load unit is 41.5 or more and the horizontal length is 13 meters or more in the table of FIG. In this case, the pipe diameter of the ventilation pipe 31k is 75A.
[0102]
In this way, the pipe diameters of the ventilation pipes 31e to 31h and 31k can be obtained.
[0103]
Next, the processing unit 4 determines whether there is a path in which a member (ventilation pipe or joint) having the diameter determined by the calculation unit 5 cannot be generated or a path in which the members overlap each other. If there is a path on which a member having the determined diameter cannot be generated or a path on which the members overlap, an error is displayed on the screen of the display unit 1.
[0104]
Next, the process proceeds to step S75, where a pipe member is generated by the processing unit 4 as shown in FIG. That is, the vent pipe having the diameter determined in step S74 and the joint having the corresponding shape are displayed at the corresponding positions on the screen of the display unit 1.
[0105]
That is, the joints 32a and 32b having the diameter corresponding to the path of the ventilation pipe to be generated in each path calculated in step S74 are read from the storage unit 3 by the processing unit 4. Then, the read joints are arranged on the screen such that the three core wires and the path of the branch pipe overlap each other at the connection points.
[0106]
Next, the processing unit 4 generates the ventilation pipes 32c and 32d having the diameter determined in step S74 between the connection points of the joints. For example, when the distance between the joints is changed, these ventilation pipes can be expanded and contracted in response to the change.
[0107]
Further, at this time, when there is a portion where the member cannot be generated or there is a portion where the members overlap each other, the processing unit 4 displays an error on the screen of the display unit 1.
[0108]
In step S75, when the processing unit 4 displays a pipe member having a predetermined diameter on the display unit 1, the processing ends.
[0109]
Next, the operation of the air-conditioning piping design display device to which the piping design device of the present invention is applied will be described with reference to the flowchart of FIG. The configuration of the air-conditioning piping design display device is basically the same as that of the drainage pipe design display device shown in FIG. First, in step S91, a piping mode is set. In this case, the mode of the air conditioning piping is set. Next, the process proceeds to step S92.
[0110]
In step S92, for example, a sizing setting screen as shown in FIG. 4 is displayed on the display unit 1. Therefore, a mouse, a column for common air conditioning and a column for air conditioning in the case of air conditioning piping are displayed on this screen. The sizing setting is performed by operating or inputting or selecting a predetermined item by operating the input setting unit 2 including a tablet or a keyboard. That is, first, the air-conditioning equipment draw-out distance a is set. As described below, when an air conditioner is arranged and connected to the main pipe at a predetermined distance from the arranged air conditioner, the distance a needs to be set.
[0111]
Next, selection of the drawing direction, that is, selection of whether the branch pipe connecting the air conditioner and the main pipe is connected to the main pipe through the right side of the air conditioner or connected to the main pipe through the left side of the air conditioner is selected. I do. Next, the drawer distance b of the air conditioner is set. Further, the distance c between the reducer 4a and an adjacent component when the reducer 4a having a different size between the inlet and the outlet is arranged is input. Next, when the 45-degree elbow is arranged, a horizontal distance d between the entrance and the exit of the 45-degree elbow is input.
[0112]
Next, an arrangement method in an air conditioning column is selected. That is, the method of generating the core wire of the return path is a direct return (a piping method not aiming at equalizing the flow rate at the inlet and the outlet) as shown in FIG. 34, or a reverse return as shown in FIG. (Piping method that can make the flow rates at the inlet and outlet almost uniform) is selected.
[0113]
Next, either the horizontal direction or the vertical direction is designated as the return route arrangement direction, and further, whether or not the gate valve is automatically created is selected.
[0114]
Next, proceeding to step S93, the air conditioners are arranged. That is, as shown in FIG. 36, the air conditioner is arranged at a predetermined position on the screen of the display unit 1 by the input setting unit 2 composed of a mouse or a tablet. At this time, only one air conditioner can be arranged, or a plurality of air conditioners can be arranged. In this case, the air conditioners 36a and 36b are arranged.
[0115]
Next, the process proceeds to step S94, and as shown in FIG. 37, by designating two points on the screen of the display unit 1 from the input setting unit 2 composed of, for example, a mouse or a tablet, Is created and displayed. When the route 37c of the outgoing main pipe is displayed on the screen, the air conditioner and the outgoing main pipe are set based on the air conditioner connection draw-out distances a and b and the pull-out direction set on the sizing screen shown in FIG. The branches 37a and 37b are determined by the processing unit 4, and are displayed on the screen.
[0116]
When the processing unit 4 determines that an unnecessary route is included in the route 37c of the main route of the forward route set by the input setting unit 2, the processing unit 4 displays a screen for inquiring whether or not to delete the route. It is displayed on the display unit 1. The user can delete the route by designating the route to be deleted on this screen.
[0117]
Next, proceeding to step S95, the arithmetic unit 5 calculates the diameter of the air-conditioning pipe to be piped on the route set by the input setting unit 2 and the route determined by the processing unit 4. In this case, the diameter of the air-conditioning pipe to be piped to the outgoing branch pipe paths 37a and 37b is 25A, and the diameter of the air-conditioning pipe to be piped to the outgoing main pipe path 37c is 50A. Then, for example, as shown in FIG. 38, a character representing the caliber calculated by the calculation unit 5 is displayed on the right side or above the corresponding route.
[0118]
Next, the processing unit 4 determines whether there is a path in which a member (outward air-conditioning pipe or joint) having the diameter determined by the calculation unit 5 cannot be generated or a path in which the members overlap each other. If there is a path on which the member having the diameter determined by 5 cannot be generated or a path on which the members overlap, an error is displayed on the screen of the display unit 1.
[0119]
Next, proceeding to step S96, the processing unit 4 determines whether the route of the main pipe of the outward route set in step S94, the air conditioning arrangement method, the outward route arrangement direction set in step S92, and the presence or absence of gate valve automatic creation. Based on this, the route of the main pipe and the branch pipe of the return path is determined, and the calculation unit 5 is caused to determine the diameter. The determined routes of the main pipe and the branch pipe of the return path are displayed at predetermined positions on the screen of the display unit 1.
[0120]
In this case, the paths 39a and 39b of the branch pipe on the return path and the path 39c of the main pipe on the return path are displayed as shown in FIG. 39, and the air conditioning to be piped to the paths 39a and 39b of the branch pipe on the return path. The diameter of each pipe is set to 25A, and the diameter of the air conditioning pipe to be connected to the main pipe path 39c of the return path is set to 50A.
[0121]
Next, the process proceeds to step S97, for example, as shown in FIG. 40, the processing unit 4 generates a pipe member. That is, the air-conditioning pipe having the diameter determined in step S95 or S96 and the corresponding joint are displayed at corresponding positions on the screen of the display unit 1. Further, the reducer is displayed at a corresponding position on the screen of the display unit 1 in accordance with the reducer generation position set in step S92.
[0122]
First, the joint calculated in steps S95 and S96 and having a diameter corresponding to the path of the air-conditioning pipe to be generated in each of the return routes is read from the storage unit 3 by the processing unit 4.
[0123]
For example, the joint 40a shown in FIG. 40 is arranged and displayed on the screen such that its two core lines overlap the paths 37a (FIG. 38) and 37c (FIG. 38) at their connection points. Similarly, the other joint 40b is arranged and displayed so that its three core lines overlap the paths 37b (FIG. 38) and 37c (FIG. 38) at the connection points thereof. The same applies to the joints 40c to 40f.
[0124]
Next, the processing unit 4 generates air-conditioning pipes (401a to 401i) having the diameter determined in steps S95 and S96 between the connection points of the respective air conditioners and the joints or between the connection points of the joints. For example, when the distance between the air conditioners is changed, these air conditioning pipes can be expanded and contracted in response to the change.
[0125]
Further, at this time, when there is a path where the member cannot be generated or a path where the members overlap each other, the processing unit 4 displays an error on the screen of the display unit 1.
[0126]
In step S97, when the processing unit 4 displays a pipe member having a predetermined diameter on the display unit 1, the processing ends.
[0127]
Next, the operation of the sprinkler piping design display device to which the piping design device of the present invention is applied will be described with reference to the flowchart of FIG. The configuration of the sprinkler piping design display device is basically the same as that of the drainage pipe design display device shown in FIG. First, in step S101, a piping mode is set. In this case, set the mode of the sprinkler piping. Next, the process proceeds to step S102.
[0128]
In step S102, a screen as shown in FIG. 42 is displayed on the display unit 1. On this screen, the sprinkler devices are arranged. That is, as shown in FIG. 42, the sprinkler device is arranged at a predetermined position on the screen of the display unit 1 by the input setting unit 2 composed of a mouse or a tablet. At this time, only one sprinkler device can be arranged, or a plurality of sprinkler devices can be arranged. In this case, the sprinkler devices 42a to 42f are arranged.
[0129]
Next, in step S103, as shown in FIG. 43, by specifying two points on the screen of the display unit 1 from the input setting unit 2 composed of, for example, a mouse or a tablet, the route of the main pipe is displayed on the screen. 43a is created and displayed. When the route 43a of the main pipe is displayed on the screen, the routes 43b to 43g of the branch pipe between the sprinkler device and the main pipe are determined by the processing unit 4, and are displayed on the screen.
[0130]
If the processing unit 4 determines that an unnecessary route is included in the route 43a of the main pipe set by the input setting unit 2, the processing unit 4 displays a screen for inquiring whether or not to delete the route. To be displayed. The user can delete the route by designating the route to be deleted on this screen.
[0131]
Next, the process proceeds to step S104, and first, the user designates the downstream side (or the upstream side) by using the four-button cursor or the mouse of the tablet and specifies the flow direction. Next, the calculation unit 5 calculates the diameter of the sprinkler pipe to be piped on the path set by the input setting unit 2 and the path determined by the processing unit 4. In this case, the diameter of the sprinkler pipe to be piped to the branch pipe paths 43b to 43g is 25A, and the diameter of the sprinkler pipe to be piped to the main pipe path 43a is 40A. Then, for example, as shown in FIG. 44, a character representing the caliber calculated by the calculation unit 5 is displayed on the right side or above the corresponding route.
[0132]
Next, the processing unit 4 determines whether there is a path in which a member (sprinkler pipe or joint) having the diameter determined by the calculation unit 5 cannot be generated or a path in which the members overlap each other. If there is a path on which a member having the determined diameter cannot be generated or a path on which the members overlap, an error is displayed on the screen of the display unit 1.
[0133]
Next, the process proceeds to step S105, where a pipe member is generated by the processing unit 4, for example, as shown in FIG. That is, the sprinkler pipe having the diameter determined in step S104 and the corresponding joint are displayed at corresponding positions on the screen of the display unit 1.
[0134]
That is, first, the external view of the joint having the diameter corresponding to the sprinkler pipe to be generated in each path calculated in step S104 is read from the storage unit 3 by the processing unit 4.
[0135]
For example, as shown in FIG. 45, the joint 45a is arranged and displayed on the screen such that its three core lines respectively overlap the paths 43a (FIG. 43), 43c (FIG. 43) and 43f (FIG. 43) at their connection points. Is done. Similarly, the joint 45b is arranged and displayed such that its three cores overlap the paths 43a (FIG. 43), 43e (FIG. 43), and 43g (FIG. 43) at their connection points.
[0136]
Next, the processing unit 4 generates sprinkler pipes 451a to 451g having the diameter determined in step S104 between the connection points of the sprinkler devices and the joints or between the connection points of the joints. These sprinkler pipes 451a to 451g are made expandable and contractible in response to, for example, a change in the distance between the sprinkler devices.
[0137]
Further, at this time, when there is a portion where a member cannot be generated or a portion where members overlap each other, the processing unit 4 displays an error on the screen of the display unit 1.
[0138]
In step S105, when the processing unit 4 displays a pipe member having a predetermined diameter on the display unit 1, the processing ends.
[0139]
Next, the operation of the fire hydrant piping design display device to which the piping design device of the present invention is applied will be described with reference to the flowchart of FIG. The configuration of the fire hydrant piping design display device basically has the same structure as the drain pipe design display device shown in FIG. First, in step S111, a piping mode is set. In this case, set the fire hydrant piping mode. Next, the process proceeds to step S112.
[0140]
In step S112, a screen as shown in FIG. 47 is displayed on the display unit 1. On this screen, fire hydrant equipment is arranged. That is, as shown in FIG. 47, the fire extinguisher is arranged at a predetermined position on the screen of the display unit 1 by the input setting unit 2 composed of a mouse or a tablet. At this time, only one fire extinguisher can be arranged, or a plurality of fire extinguishers can be arranged. In this case, a fire extinguisher 47a is provided.
[0141]
Next, the process proceeds to step S113, where two points on the screen of the display unit 1 are designated by the input setting unit 2 composed of, for example, a mouse or a tablet, as shown in FIG. A route 48a is created and displayed. When the route 48a of the main pipe is displayed on the screen, the routes 48b and 48c of the branch pipe between the fire extinguisher and the main pipe are determined by the processing unit 4, and are displayed on the screen.
[0142]
When the processing unit 4 determines that the unnecessary route is included in the route 48a of the main pipe set by the input setting unit 2, the processing unit 4 displays a screen for inquiring whether or not to delete the route. To be displayed. If the user wants to delete the route, and instructs to delete the route on this screen, the processing unit 4 deletes the route.
[0143]
Next, proceeding to step S114, the user first designates the downstream side (or the upstream side) using the four-button cursor or mouse of the tablet, and designates the flow direction. Next, the arithmetic unit 5 calculates the diameter of the fire hydrant pipe to be piped on the route set by the input setting unit 2 and the route determined by the processing unit 4. In this case, the diameter of the fire hydrant pipe to be piped to the branch pipe path 48b is 40A, and the diameter of the fire hydrant pipe to be piped to the main pipe path 48a is 40A. Then, as shown in FIG. 49, for example, a character representing the caliber calculated by the calculation unit 5 is displayed on the right or upper side of the corresponding route.
[0144]
Next, the processing unit 4 determines whether there is a path in which a member (fire hydrant pipe or joint) having the diameter determined by the calculation unit 5 cannot be generated or a path in which the members overlap each other. If there is a path on which a member having the determined diameter cannot be generated or a path on which the members overlap, an error is displayed on the screen of the display unit 1.
[0145]
Next, the process proceeds to step S115, for example, as shown in FIG. 50, the processing unit 4 generates a pipe member. That is, the fire hydrant pipe having the diameter determined in step S114 and the corresponding joint are displayed at corresponding positions on the screen of the display unit 1.
[0146]
That is, first, the external view of the joint having the diameter corresponding to the fire hydrant pipe to be generated in each path, calculated in step S114, is read from the storage unit 3 by the processing unit 4.
[0147]
For example, the joint 50a shown in FIG. 50 is arranged and displayed on the screen such that its two cores overlap the paths 48b (FIG. 48) and 48c (FIG. 48) at the connection points thereof. Similarly, the joint 50b is arranged and displayed such that its two cores overlap the paths 48a (FIG. 48) and 48b (FIG. 48) at the connection points thereof.
[0148]
Next, the processing unit 4 generates the fire hydrant pipes (501a to 501c) having the diameter determined in step S114 between the connection points of each fire hydrant device and the joint or between the connection points of the joints. These fire hydrant pipes (501a to 501c) are made expandable and contractible in response to, for example, a change in the distance between the fire hydrant devices.
[0149]
Further, at this time, when there is a portion where the member cannot be generated or there is a portion where the members overlap each other, the processing unit 4 displays an error on the screen of the display unit 1.
[0150]
Next, the process proceeds to step S116, where the pipe pressure loss of the pipe created in steps S111 to S115 is calculated, that is, the resistance value received when water flows through the pipe is calculated, and the pipe head calculation, that is, a predetermined value is performed. When water is supplied to the pipe by the pump, a capacity indicating how many meters of water can be lifted at a height of several meters is calculated, and the process is terminated.
[0151]
The pipe pressure loss calculation and the pipe head calculation in step S116 described above can be similarly performed not only for the fire hydrant pipe but also for the drain pipe, the water supply pipe, the ventilation pipe, the air conditioning pipe, or the sprinkler pipe.
[0152]
Next, the operation of the duct design display device to which the duct design device of the present invention is applied will be described with reference to the flowchart of FIG. The configuration of the duct design display device is basically the same as that of the drain pipe design display device shown in FIG.
[0153]
When manually inputting various setting values relating to the duct and causing the apparatus to execute the caliber calculation and the automatic arrangement of the duct, the processing from step S121 to S126 is executed. On the other hand, when all the processes are performed by the apparatus, the processes of steps S124 to S126 are performed. Here, the processing of steps S121 to S126 will be sequentially described.
[0154]
First, in step S121, the specification of the duct is set. For example, the processing unit 4 displays a duct specification list display screen as shown in FIG. On this screen, the duct specifications already registered and stored in the storage unit 3 are displayed. Then, the part of the currently set specification is, for example, highlighted. In this case, the specification of the air-conditioning air supply is selected.
[0155]
Here, the specification names of the specification numbers 1 to 5 cannot be registered or deleted, but the specification names of the specification numbers 6 to 15 can be freely registered or deleted. In this screen, by operating the input setting unit 2 composed of a mouse, a tablet, or a keyboard in order to change the specification and designating the “evacuation exhaust” of the specification number 4, as shown in FIG. Is highlighted. In this manner, a predetermined duct specification set in advance can be selected.
[0156]
On the other hand, when a new duct specification is set, first, the selection item “new” displayed on the screen is designated by operating the input setting unit 2. As a result, as shown in FIG. 54, the selection item “New” and the specification name input field are highlighted, so the input setting unit 2 is operated to input the specification name, for example, Shinjuku Building (air supply). After inputting the specification name, when the selection item "confirmation" is instructed, the display unit 1 displays a duct specification content display setting screen (FIG. 57) as described later.
[0157]
On this screen, after inputting predetermined items, by instructing the selection item "confirmation" displayed at the upper right of the screen, registration of a new duct specification is completed, and a screen as shown in FIG. Will be displayed. Thus, the newly registered specification is registered in the last line of the duct specification list display screen, in this case, specification number 6. In this case, the number of duct specifications that can be newly registered is a total of ten duct numbers 6 to 15.
[0158]
To delete a specification that has already been registered, first, a specification to be deleted from among the specifications displayed on the screen is designated by operating the input setting unit 2, and the specification is highlighted. Next, the selection item “delete” displayed on the screen is designated by operating the input setting unit 2. When the selection item “delete” is instructed, the selection item “delete” is highlighted and a confirmation message as shown in FIG. 56 is displayed on the screen.
[0159]
If deletion is allowed, the user inputs the “Y” key using the keyboard constituting the input setting unit 2 or clicks the left button of the four-button cursor of the tablet. As a result, the highlighted specification is deleted, and the selection item “delete” returns to the normal display state. On the other hand, when canceling the deletion, the user inputs the "N" key on the keyboard or clicks the right button of the four-button cursor of the tablet. As a result, the deletion is stopped, and the selection item “delete” returns to the normal display state. However, the specifications that can be deleted are limited to those registered in specification numbers 6 to 15.
[0160]
When changing the contents of the already registered duct specification, the input setting unit 2 is operated to instruct the selection item “change” displayed on the duct specification list display screen. As a result, a duct specification content display setting screen as shown in FIG. 57 is displayed. First, an item to be changed is specified, and then the content of the item is input. Thereby, the content of the item can be changed. By repeating this operation, the contents of a plurality of items can be changed. If the user wants to cancel the change on the way, he or she designates the selection item “Cancel”.
[0161]
By instructing the selection item "confirmation" on the duct specification display setting screen, the specification set on this screen at that time is determined. As a result, the subsequent design and arrangement of the duct will be performed based on the specifications set here.
[0162]
Next, a method of setting the duct specification content on the duct specification content display setting screen shown in FIG. 57 will be described. This screen shows a screen displayed in the case of a new creation, and a preset initial value is displayed in each item.
[0163]
By operating the input setting section 2 on this screen, a specification item to be set or changed is selected, and the content is set or changed. As the straight pipe length (straight pipe length) of the specification item, as shown in FIG. 58, a fixed length when splitting the straight pipe is set. At this time, the length is set to be larger than twice the length of the flange portion shown in FIG. In this case, 1820 mm (millimeter) is set as an initial value.
[0164]
As shown in FIG. 59, the flange width of the square duct is set in the specification item flange. In this case, the minimum value that can be set is 1 mm. In this case, 30 mm is set as an initial value. The elbow curvature of the specification item is set to the curvature of the elbow (90 degrees). As shown in FIG. 60, the elbow curvature is a numerical value obtained by dividing a bending radius (R) by a duct width (W), and is represented by the following equation.
[0165]
Elbow curvature = R / W
[0166]
FIG. 61 (a) shows an elbow when the elbow curvature is 0.5, and FIG. 61 (b) shows an elbow when the elbow curvature is 1.0. Further, FIG. 61 (c) shows an elbow when the elbow curvature is 2.0.
[0167]
The elbow curvature can be input and set in units of 0.1 in the range of 0.5 to 5.0 for the square duct specification and in the range of 1.0 to 5.0 for the round duct specification. In this case, 1.0 is set as an initial value.
[0168]
As the shape (shape type) of the specification item, either a square duct or a round duct is selected. In this case, the square duct is selected as the initial value and is highlighted. In addition, as the display type of the specification item, either a double track or a single track can be selected. In this case, the double track as the initial value is selected and highlighted. When a double track is selected, the duct is displayed in relatively detail so that its shape can be recognized by a plurality of lines, and when a single track is selected, the duct is displayed as a single line.
[0169]
As the display color (color number) of the specification item, one of 12 colors can be selected. In this case, the color number 4 is selected as the initial value and is highlighted. Further, as the pen number of the specification item, one of eight line types having different line thicknesses and densities can be selected. In this case, the pen number 3 as the initial value is selected and highlighted.
[0170]
As the material of the specification item, one can be selected from among four types of “zinc-iron plate”, “vinyl chloride”, “stainless steel”, and “hard ambi”. In the present case, a galvanized sheet is selected.
[0171]
When "Zinc iron plate" is selected as the material of the specification item, "Low speed" or "High speed" is selected as the effective wind speed specification. In this case, the low speed is selected and highlighted. When "vinyl chloride" is selected as the material of the specification item, "low speed" or "high speed" is selected as the effective wind speed specification. In this case, the low speed is selected and highlighted. When “hard ambi” is selected as the material of the specification item, any one of 150 (mmAq) or less, 151 to 200 (mmAq), or 201 to 300 mmAq is selected as the effective wind speed specification. In this case, 150 or less as the initial value is selected and highlighted.
[0172]
As the height of the specification item, any one of the lower surface, the upper surface, and the center is selected as the height at which the ducts are arranged when the ducts are arranged. In this case, the lower surface is selected and highlighted. FIG. 62A shows a case where the lower surface of the duct is set to the set height, and the duct is designed so that the height of the lower surface of the duct matches the set height set at the time of creating the elevation. . FIG. 62B shows a case where the upper surface of the duct is set at the set height. Further, FIG. 62 (c) shows a case where the center of the duct is set at the set height.
[0173]
As shown in FIG. 63, the shapes of the elbow, the hopper, the run-out hopper, the two-way branch (1), the two-way branch (2), and the three-way branch are set according to the set mating height (lower surface, upper surface, center). Respectively.
[0174]
On the duct specification content display setting screen shown in FIG. 57, as described above, if the user wants to cancel the setting of the specification item while setting the specification item, the input setting unit 2 is operated to display the upper right of the screen. By instructing the displayed selection item “Cancel”, each specification item (duct attribute) is not changed, and the duct specification list display screen shown in FIG. 52 is displayed.
[0175]
In the duct specification display setting screen shown in FIG. 57, when it is desired to confirm the currently displayed or selected specification, the input setting unit 2 is operated to instruct the selection item "confirm" displayed on the upper right of the screen. I do. Thereby, the currently displayed specification content is determined. Thereafter, the duct specification list display screen shown in FIG. 52 is displayed.
[0176]
Next, in step S122, the duct size is set. First, the processing unit 4 displays a duct size calculation method selection screen as shown in FIG. On this screen, the user operates the input setting unit 2 to specify the selection item “total pressure method” when the total pressure method is selected as the calculation method, and to select the “constant speed method” when selecting the constant velocity method as the calculation method. ". When the dimension calculation is not performed, "no calculation" is designated.
[0177]
When the total pressure method is selected, the value set as the friction loss is validated and used for dimension calculation. When changing the value of the friction loss, the input setting unit 2 is operated to input a predetermined value. When the constant velocity method is selected, the value set as the wind velocity is made valid and used for dimension calculation. When changing the value of the wind speed, the input setting unit 2 is operated to input a predetermined value.
[0178]
For the dimension standard, select one of the selection items “reference” or “not reference”. When the selection item “refer to” is selected, the duct dimensions are optimized according to the standard when the duct is created. On the other hand, when the selection item “do not refer” is selected, the duct dimensions are not optimized in accordance with the standard.
[0179]
When the setting on the duct size calculation method selection screen is completed, in the case of the square duct specification, the processing unit 4 displays a condition setting screen for the square duct specification as shown in FIG. By operating the input setting unit 2 on this screen, the air volume at each connection point of the square duct is input, and then the dimensions of the top (height) and width (width) are input as the duct dimensions. Then, by indicating one of the selection items “heaven” or “consistent”, either “heaven” or “consistent” is selected.
[0180]
Next, by instructing the selection item “confirmation”, the set value and the selection item are determined, and the calculation unit 5 calculates the duct size based on the dimension value which is selected from the top or the consistency. Done.
[0181]
In the case of the round duct specification, the processing unit 4 displays a condition setting screen for the round duct specification as shown in FIG. On this screen, the input setting unit 2 is operated to input the air volume at each connection point of the round duct. After the setting, when the selection item "confirmation" is instructed, the set air volume is confirmed.
[0182]
Next, when the total pressure method is selected on the screen of FIG. 64, as shown in FIG. 67, for example, the wind speed is calculated by the calculation unit 5 from the friction loss and the air volume input as the condition, and the calculation result is calculated by the processing unit 4. Is displayed on the display unit 1. In this example, the wind speed at the connection point 1 is 4.2, the wind speed at the connection point 2 is 3.3, the wind speed at the connection point 3 is 6.1, and the wind speed at the connection point 4 is 5.5.
[0183]
On the other hand, when the constant velocity method is selected on the screen of FIG. 64, as shown in, for example, FIG. 68, the calculation unit 5 calculates the friction loss from the wind speed and the air volume input as the condition, and the processing result is calculated by the processing unit 4. Is displayed on the display unit 1. In this example, the friction loss at the connection point 1 is 0.20, the friction loss at the connection point 2 is 0.10, the friction loss at the connection point 3 is 0.20, and the friction loss at the connection point 4 is 0.30. .
[0184]
Next, the process proceeds to step S123, where the member setting is performed. The processing unit 4 displays a member generation setting screen as shown in FIG. 69, for example. In this screen, whether or not to make an inquiry at the time of automatic placement, which will be described later with reference to FIG. 81, is selected by operating the input setting unit 2 and instructing the selection item “Yes” or “No”. .
[0185]
Next, only one member of the square duct and one member of the round duct to be arranged on the route line branched in two directions are selected. Similarly, only one member of the square duct and one member of the round duct to be arranged on the route lines branched in three directions are selected. Similarly, only one member of the square duct to be arranged on the route line branched in four directions is selected. Further, in the case of a square duct, a device to be connected to the last outlet of the duct is selected. In the case of a round duct, only the devices indicated here can be connected.
[0186]
When the selection item "Yes" is selected on the screen shown in FIG. 69, an inquiry is made as to which member is to be arranged for each member on the screen shown in FIG. At this time, the members set in FIG. 69 are displayed as initial values. Then, the user operates the input setting unit 2 to select a desired member. On the other hand, when the selection item “none” is selected, no inquiry is made in FIG. 82, and the members set in FIG. 69 are unconditionally arranged.
[0187]
The processing up to this point is the processing required when the specifications, dimensions, members, and the like of the duct are manually set. Therefore, when the apparatus performs all of these processes, only the processes of steps S124 to S126 described below are performed.
[0188]
In step S124, a route line is drawn. First, the processing unit 4 displays a use selection screen as shown in FIG. 70 on the display unit 1, for example. By operating the input setting unit 2 on this screen, either the air conditioning path or the smoke exhaust path is selected. In this case, the air conditioning path has been selected. Here, when the air conditioning route is selected, the route line is drawn as the route of the air conditioning duct. When a smoke exhaust route is selected, a route line is drawn as a route of the smoke exhaust duct.
[0189]
Next, the route line of the air conditioning route or the smoke exhaust route selected in FIG. 70 is set. In this case, an air conditioning path is set. The display unit 1 displays an operand selection screen as shown in FIG. 71 by the processing unit 4. This screen displays “absolute”, “relative”, “on-line point”, “line end point”, “line intersection”, “waterdrop”, “rounding”, and “device” as operands. When the operand "absolute" is selected, a predetermined position on the screen is specified by setting the origin (0, 0) at the lower left XY coordinate on the screen and operating the keyboard to input the XY coordinate values. Can be.
[0190]
When the operand “relative” is selected, the XY coordinates at a predetermined position on the screen are set as the reference points, and the keyboard is operated to input the XY coordinate values relative to the reference points, respectively, so that a predetermined value on the screen is displayed. The position can be specified. When "on-line point" is selected as the operand, the position on the screen manually specified using the four-button cursor is corrected to a nearby position on the line already displayed on the screen.
[0191]
When the operand “line end point” is selected, the position on the screen manually specified using the four-button cursor is corrected to the position of the line end point already displayed on the screen in the vicinity thereof. When the operand "line intersection" is selected, the position on the screen manually specified by using the four-button cursor is corrected to the position of the line intersection already displayed on the screen in the vicinity thereof. When the operand "waterdrop" is selected, a perpendicular drawn from a position on the screen manually designated by using the four-button cursor on a line already displayed on the screen is displayed.
[0192]
When the operand “round” is selected, when a predetermined position on the screen is manually designated using a four-button cursor, the cursor displayed on the screen is displayed on the screen in a predetermined number of dots, for example, 50 dots. It moves in dot units or 100 dot units. Further, when the operand “device” is selected, the position on the screen manually specified by using the four-button cursor is corrected to the position of the connection point of the device already displayed on the screen in the vicinity thereof.
[0193]
From among the operands described above, for example, the operand “rounding” is selected, and as shown in FIG. 72, the cursor displayed on the screen is started by operating the four-button cursor of the tablet constituting the input setting unit 2, for example. The start point 72a is designated by moving the cursor to the point 72a and clicking the upper button of the four-button cursor.
[0194]
Next, the cursor is moved to the passing point 72a, and the passing point 72a is designated by clicking the upper button of the four-button cursor. Similarly, by moving the cursor to the passing point 72c and clicking the upper button of the four-button cursor, the passing point 72c is designated. Further, by moving the cursor to the end point 72d and clicking the left button of the four-button cursor, the end point 72d is designated and the route line is determined. When the end point is determined, a route indicated by a plurality of passing points and indicated by a solid line is indicated by a dashed line as shown in FIG. In this way, a route line can be drawn.
[0195]
In this way, by selecting the operand "round", the cursor moves on the screen by a predetermined number of dots, for example, 50 or 100 dots. This makes it possible to easily specify a horizontal or vertical line with respect to the screen by manual operation. At this time, the designated passing point may be displayed after being corrected in the horizontal, vertical, or 45-degree direction.
[0196]
Next, in step S125, the caliber of each part of the path line drawn in step S124 is calculated. First, the processing unit 4 displays a duct type selection screen as shown in FIG. By operating the input setting unit 2 on this screen, either the corner or the circle is selected as the duct type. When a corner is selected here, the calculation unit 5 calculates the diameter of the square duct. On the other hand, when a circle is selected, the calculation unit 5 calculates the diameter of the round duct.
[0197]
Next, a message "Please indicate the core line on the most upstream side of the main pipe" as shown in FIG. 75 is displayed on the display unit 1 by the processing unit 4, so that the input setting unit 2 is operated and FIG. A predetermined position 76a on the most upstream path line of the path line shown in FIG. Thus, the processing unit 4 displays an arrow indicating the flow direction on the designated route line in the route direction, and also displays a message “Is this direction?” As shown in FIG. 77.
[0198]
If the direction of the arrow displayed in FIG. 76 is the same as the flow direction, the user inputs the “Y” key using the keyboard constituting the input setting unit 2 or clicks the left button of the four-button cursor of the tablet. Thereby, the flow direction is determined. On the other hand, if the direction of the arrow displayed in FIG. 76 is opposite to the flow direction, the user inputs the “N” key using the keyboard constituting the input setting unit 2 or clicks the right button of the four-button cursor. As a result, the direction of the arrow displayed in FIG. 76 is reversed, and a message as shown in FIG. 77 is displayed on the display unit 1 again. Thereafter, the same operation as that described above is repeated.
[0199]
In the screen of FIG. 77, when the “Y” key is input by the keyboard or the left button of the four-button cursor is clicked and the flow direction is determined, the processing unit 4 outputs a message “ Please set a consistent value "is displayed on the display unit 1. Here, by operating the input setting unit 2, a value consistent with the duct is input and set. In this case, for example, a value of 100 is set.
[0200]
When a consistent value is input, the arithmetic unit 5 calculates the diameter (in the case of a round duct) or the ceiling (in the case of a square duct) and the height in each part of the path line shown in FIG. As shown in FIG. 79, the calculation result is displayed at a corresponding portion on each path line.
[0201]
Next, the process proceeds to step S126, in which the duct members and the like are automatically arranged. The processing unit 4 displays a route line on the display unit 1 as shown in FIG. On this screen, the user operates the input setting unit 2 to indicate a predetermined position 80a on the route line on which the caliber has been calculated, thereby indicating a predetermined route line. At this time, in FIG. 69, if “Yes” is selected as the inquiry at the time of member occurrence, the processing unit 4 sends the inquiry of that type on the route line that has just been indicated on this screen in FIG. The display color of the part where the component to be made is placed changes, and a selection window for selecting a part that can be placed in that part is displayed in the upper right part of the screen. FIG. 81 shows a screen on which the selection window is displayed. FIG. 82 is a diagram showing a selection window displayed at the upper right of FIG. In this case, two types of elbows of the square duct are displayed.
[0202]
In the selection window shown in FIG. 82, by operating the input setting unit 2 and selecting one of the two members displayed as the member type, the selected member is moved to a predetermined position on the route. Be placed. In this case, the elbow is arranged at a predetermined position. Similarly, devices that can be arranged in other parts on the route are selected and arranged at predetermined positions.
[0203]
Next, in the case of arranging the outlet, the distance between the height of the path line and the height at which the outlet should be installed is the set neck length, that is, the distance from the path line to the outlet downward. 83, the message "Change neck length to path line height. Do you want to continue processing?" Is displayed on the display unit 1 by the processing unit 4 as shown in FIG. This is for inquiring whether to change the neck length and continue the processing so that the distance from the position of the outlet to the route line becomes the neck length.
[0204]
To continue the processing, the user inputs the “Y” key from the keyboard constituting the input setting unit 2 or clicks the left button of the four-button cursor of the tablet. On the other hand, when canceling the process, the user inputs the "N" key from the keyboard or clicks the right button of the four-button cursor.
[0205]
After the "Y" key is input from the keyboard or the left button of the four-button cursor of the tablet is clicked, the neck length is changed to the path line height by the processing unit 4, and then the balloon outlet is moved to a predetermined position. Is displayed, and the process is terminated.
[0206]
Further, in the above embodiment, a predetermined range on the route calculated as a square duct is designated by operating the tablet's four-button cursor, and only that portion is re-calculated as a round duct with a circular duct. It is possible to do so. Conversely, first, specify a predetermined range on the route whose diameter has been calculated as a round duct by operating the four-button cursor, and let only that part be a square duct and recalculate the top Is also possible. Therefore, it is possible to easily and quickly change the design from the square duct to the round duct or from the round duct to the square duct.
[0207]
In the case of a square duct, it is also possible to designate a predetermined portion on the route by operating a four-button cursor and change only the width of the portion. At this time, the height is recalculated by the constant pressure method. In the case of a square duct, it is also possible that the size consistent with the ceiling is determined according to a predetermined standard size group (such as the Ministry of Construction specifications or the Air Conditioning and Sanitation Engineering Society specifications).
[0208]
Further, at the part where the route branches, the processing part 4 can display the branch part on the display unit 1 in a branching method set in advance. As a result, even a CAD operator having no specialized knowledge, for example, can easily and quickly design and draw a duct.
[0209]
Next, the operation of the air conditioning water piping design display device to which the piping design device of the present invention is applied will be described with reference to the flowcharts of FIGS. 84 and 85. The configuration of the air-conditioning water piping design display device is basically the same as that of the drainage pipe design display device shown in FIG.
[0210]
First, in step S131, the connected device is arranged at a predetermined position on the screen. Next, the process proceeds to step S132, in which path drawing setting is performed. The processing unit 4 displays a sizing setting screen as shown in FIG. 86 on the display unit 1, for example, so that a mouse, mouse, etc. The sizing setting is performed by operating or inputting or selecting a predetermined item by operating the input setting unit 2 including a tablet or a keyboard. That is, first, the air-conditioning equipment draw-out distance a is set. When an air conditioner is arranged and connected to the main pipe at a predetermined distance from the arranged air conditioner, the distance a needs to be set.
[0211]
Next, selection of the drawing direction, that is, selection of whether the branch pipe connecting the air conditioner and the main pipe is connected to the main pipe through the right side of the air conditioner or connected to the main pipe through the left side of the air conditioner is selected. I do. Next, the drawer distance b of the air conditioner is set. Further, the distance c between the reducer 4a and the adjacent component when a reducer having a different size between the inlet and the outlet is arranged is input.
[0212]
Next, an arrangement method in an air conditioning column is selected. That is, the method of generating the core wire of the return path may be a direct return (a piping method not intended to equalize the flow rates at the inlet and the outlet) as shown in FIG. 34, or a reverse method as shown in FIG. Return (Piping method that can make the flow rates at the inlet and outlet almost uniform) is selected. Next, when the return route is automatically generated in parallel with the outward route, the designation of whether to arrange the return route in the horizontal direction or the vertical direction is determined as the return route arrangement direction in either the horizontal direction or the vertical direction. This is done by specifying When the reverse return is selected as the arrangement method, the folding direction is also determined according to the arrangement direction.
[0213]
Further, whether or not the gate valve is automatically created is determined by selecting "Yes" or "No". When "Yes" (perform automatic creation) is selected, a gate valve is automatically generated on the branch pipe between the main pipe of the plotted route line and the device (fan coil). At this time, the gate valve is generated at the center of the branch pipe closest to the main pipe.
[0214]
Next, in step S133, the use selection screen as shown in, for example, FIG. 87 is displayed on the display unit 1 by the processing unit 4, and the corresponding use is selected by operating the input setting unit 2. In this case, since it is the outward path of the air-conditioning water pipe, the air-conditioning path (outbound) is selected.
[0215]
Next, the input setting unit 2 is operated to draw a route of the air-conditioning water pipe. For example, by operating the four-button cursor of the tablet, the cursor displayed on the display unit 1 is moved to a predetermined position, and the start point is indicated by, for example, clicking the upper button. Next, the cursor is moved to another predetermined position, and the passing point is indicated by clicking the upper button. By repeating the same operation, a plurality of passing points are designated, a predetermined route is drawn, and finally, an end point is designated by clicking the left button of the four-button cursor, and the route is determined. In this way, a predetermined route can be drawn.
[0216]
When the drawing of the route is completed, the process proceeds to step S135, where conditions for caliber calculation are set. For example, a system list screen as shown in FIG. 88 is displayed on the display unit 1 by the processing unit 4, and the material of the pipe for which the caliber is to be calculated is selected. The system name is the file name of the system master file.In this master file, information on pipes and joint files is recorded, and the arrangement of straight pipes and parts can be performed with reference to these. It is possible. In this case, the fourth system name is selected. As a result, with reference to the pipe material and the joint file recorded in the system master file indicated by the system name, the straight pipes and parts described later are arranged.
[0217]
Next, the input setting unit 2 is operated to instruct a route line for which the caliber calculation is performed. Here, a method of instructing a route line will be described using an example of a water supply pipe, but the same applies to an air-conditioning water pipe. For example, by operating the input setting unit 2 on the route line of the water supply pipe as shown in FIG. 89, the position 89a on this route line is indicated. Thereby, a route line can be specified.
[0218]
Next, as shown in FIG. 90, the uppermost stream or the lowermost stream on the route line is designated according to the use of the previously designated route line. For water supply pipes, hot water supply pipes, air conditioning pipes (outbound), sprinklers, and fire hydrants, indicate the most upstream, and for sewage pipes, miscellaneous drainage pipes, ventilation pipes, and air conditioning pipes (return path), indicate the most downstream. . In this case, since it is the air-conditioning water pipe (outgoing path), a predetermined position 90a on the most upstream route line is designated as in the case of the air-conditioning pipe (outgoing path).
[0219]
Next, as shown in FIG. 90, the flow direction is displayed by an arrow, and a message “Is this direction?” Is displayed on the screen as shown in FIG. When the flow direction is the direction specified by the arrow, the user inputs the “Y” key of the keyboard constituting the input setting unit 2 or clicks the left button of the four-button cursor of the tablet. Thereby, the flow direction is determined.
[0220]
On the other hand, in FIG. 90, when the flow direction is not the direction indicated by the arrow, the user inputs the “N” key on the keyboard or clicks the right button of the four-button cursor on the tablet. As a result, an arrow pointing in the opposite direction is displayed on the screen, and this flow direction can be designated and confirmed.
[0221]
Next, an instruction is given to the connected device. Here, the case of calculating the diameter of the ventilation path will be described as an example, but the same is basically applied to the outward path of the air-conditioning water pipe. First, the processing unit 4 displays a screen as shown in FIG. Here, the ventilation path is indicated by a dotted line, and the drainage path is indicated by a chain line. Here, the path line of the branch part where the ventilation path and the drainage path branch are displayed in order, for example, in red.
[0222]
That is, first, the ventilation path 92a is displayed in red. In FIG. 92, the ventilation path 92a is indicated by a thick dotted line. Next, on the screen shown in FIG. 93, by specifying the positions 93a and 93b, a rectangular area having the positions 93a and 93b as vertices is set. Thereby, the device in this rectangle can be designated as the device covered by the ventilation path 92a in FIG.
[0223]
When the device to be served by the ventilation path 92a is set, the ventilation path 92b in FIG. 92 is displayed in red, and the device to be served by the ventilation path 92b is designated in the same manner as described above. Similarly, the device assigned to the ventilation path 92c in FIG. 92 is designated. In this way, a device to be connected to a predetermined route is specified.
[0224]
When the condition setting for performing the caliber calculation is completed in this way, the process proceeds to step S136, and the caliber of the route drawn in step 134 is computed by the computing unit 5 based on the set conditions. The calculation result is supplied to the processing unit 4, and the processing unit 4 supplies it to the display unit 1. The display unit 1 displays a predetermined number indicating the caliber near the corresponding route based on the calculation result supplied from the processing unit 4, and based on the system master file selected in step S135. A corresponding straight pipe is generated above and arranged at a predetermined position, and a part such as a joint having a corresponding diameter is generated and arranged at a predetermined position.
[0225]
When the drawing of the outward path of the air-conditioning water pipe is completed in this way, next, the drawing of the return path of the air-conditioning water pipe is performed.
[0226]
In step S141 of FIG. 85, the use of the return route of the air-conditioning water pipe is selected. The processing section 4 displays a use selection screen as shown in FIG. 94 on the display section 1. By operating the input setting section 2, the air conditioning path (return) is selected here.
[0227]
Next, the processing unit 4 displays the device connection angle setting screen as shown in FIG. 95 on the display unit 1. The device displayed as an operand is designated by using the device as an operand, and the designated device is designated. Either 45 degrees or 90 degrees is selected for each device as the connection angle between the device and the path. Here, 90 degrees is selected.
[0228]
In addition, by using the “device” as an operand in this way, the cursor displayed on the display unit 1 is moved by manually operating a four-button cursor of, for example, a tablet constituting the input setting unit 2, and The cursor position is corrected to the position of the target device only by designating the vicinity of the device, so that the cursor position can be easily and quickly moved to the position where the device is displayed.
[0229]
Next, the process proceeds to step S142, in which the input setting unit 2 is operated to designate a forward route for which a drawing has been made and for which the caliber has been calculated. Here, a predetermined position 96a on the outward route is indicated.
[0230]
Next, in step S143, the direction of the return route is specified. That is, when the horizontal direction is set as the return route arrangement direction set in FIG. 86, the input setting unit 2 is operated to instruct the arrangement direction. In this case, a predetermined position 96b on the screen is designated as the arrangement direction. As a result, the return route is arranged parallel to a position shifted by a predetermined distance in the lower direction on the screen with respect to the forward route.
[0231]
On the other hand, when the vertical direction is set as the return route arrangement direction set in FIG. 86, the processing unit 4 displays an air conditioning route (return) drawing position setting screen as shown in FIG. Therefore, the user operates the input setting unit 2 to select whether to arrange the return route at a position higher or lower than the forward route. For example, when the selection item “high” is selected, the return route is arranged in a position higher than the forward route in parallel. On the other hand, when the selection item “low” is selected, the return route is arranged parallel to a lower position with respect to the outward route.
[0232]
When the return path is arranged, the distance between the core of the pipe arranged on the outward path and the core of the pipe arranged on the return path is a distance of at least three times the diameter of each pipe. Can be arranged only apart. Thereby, even when the heat insulating material is attached around the air conditioning water pipes arranged on the outward route and the return route, the air conditioning water pipings come into contact with each other, and it is impossible to actually perform the piping. Such a situation can be prevented.
[0233]
Next, in step S144, the calculation unit 5 calculates the diameter of the return route. Then, the return path is automatically created based on the calculation result of the caliber calculation and the set value specified or selected in steps S141 to S143. FIG. 98 shows a screen on which a return route is automatically created. Here, an example in which the aperture is not displayed for easy viewing is shown.
[0234]
In this manner, the return path of the air-conditioning water pipe can be automatically drawn.
[0235]
Next, a description will be given of a method of routing when connecting a route line to a device. On the sizing setting screen shown in FIG. 99, a drawer distance a and a drawer distance b are set in advance. Further, the user selects a drawing direction instructing whether to draw the drawing path to the right side or the left side of the device. For example, if right is selected as the drawing direction, as shown in FIG. 100, the branch pipe route from the main pipe route to the device is routed from the right side of the device. Such routing is performed when the connection direction of the device is opposite to the path to be connected.
[0236]
When the connection direction of the device is toward the connection route, the set values of the withdrawal distances a and b set in FIG. 99 are invalid, and as shown in FIG. 101, the branch pipe route from the main pipe route to the device. Is set as a straight line without routing.
[0237]
Next, an example of a method of calculating a minimum interval between pipes will be described. When a return route is automatically created and a reverse return is instructed as an arrangement method, when the forward route tube and the return route tube are automatically created as shown in FIG. 102, the pipe arrangement distance L is set as shown in FIG. The pipe diameter (nominal diameter) and the distance L between the pipes can be determined based on the pipe diameter in accordance with a table in which the pipes are associated with each other.
[0238]
In each of the above embodiments, when the route of the main pipe is set, the route of the branch pipe between the connected device and the main pipe is determined by the processing unit 4, but the user sets the route of the branch pipe. It is also possible to do so. Further, a part of the route of the branch pipe connected between the connected device and the main pipe may be set by the user.
[0239]
