It is designed to be displayed. That is, the input setting unit 2 can arrange the sanitary equipment.

The input setting unit 2 can set the route of the main pipe of the drain pipe, which is displayed on the display unit 1. The processing unit 4 determines the path of the branch pipe according to the path of the main pipe set by the input setting unit 2, and the arithmetic unit 5 determines the diameters of the main pipe and the branch pipe determined by the processing unit 4. Has been done.

Next, the operation will be described with reference to the flow chart shown in FIG. First, in step S41, the piping mode is set. In this case, set the drain pipe mode. Next, it progresses to step S42.

In step S42, the sizing setting screen as shown in FIG. 4, for example, is displayed on the display unit 1. Next, by operating the input setting unit 2 composed of, for example, a mouse or a keyboard in a predetermined column (common column in the case of a drainage pipe) of this screen, inputting or selecting a predetermined item, Make sizing settings. That is, first, the sanitary equipment pull-out distance a is set. When the sanitary equipment is arranged as will be described later and is connected to the main pipe at a predetermined distance from the arranged sanitary equipment, it is necessary to set the distance a.

Next, selection of the drawing direction, that is, the branch pipe connecting the sanitary equipment and the main pipe is connected to the main pipe through the right side of the sanitary equipment or is connected to the main pipe through the left side of the sanitary equipment. Or select. Next, the pull-out distance b of the sanitary equipment is set. Further, when the reducer 4a in which the sizes of the inlet and the outlet are different is arranged, the reducer 4
Enter the distance c between a and the adjacent part. Then 4
45 degree elbow entrance when arranging 5 degree elbow,
Enter the horizontal distance d of the exit.

Next, in step S43, the sanitary equipment 5
Arrange a and 5b. That is, as shown in FIG. 5, a graphic corresponding to a sanitary device is arranged and displayed at a predetermined position on the screen of the display unit 1 by the input setting unit 2 including a mouse or a tablet. At this time, place only one sanitary device,
It can be displayed, or a plurality of sanitary devices can be arranged and displayed.

Next, in step S44, as shown in FIG. 6, two points (or more points) on the screen of the display unit 1 are designated by the input setting unit 2 including, for example, a mouse or a tablet. By doing so, the route 6a of the main pipe is created and displayed on the screen. When the route of the main pipe is displayed on the screen, the route of the branch pipe between the sanitary device and the main pipe is determined based on the sanitary equipment connection withdrawal distances a and b and the withdrawal direction set in the sizing screen shown in FIG. It is determined by the processing unit 4 and displayed on the screen.

Further, when the processing unit 4 determines that the route of the main pipe set by the input setting unit 2 includes an unnecessary route, it displays a screen asking whether the route should be deleted. Displayed in Part 1. By specifying to delete the route on this screen, the user can
The route can be deleted.

Next, in step S45, the user uses the four-button cursor of the tablet or the mouse to instruct, for example, the downstream side (or the upstream side),
Specify the flow direction. Next, the caliber of the route set by the input setting unit 2 and the caliber of the route determined by the processing unit 4 is calculated by the calculation unit 5, and, for example, as shown in FIG. The character representing is displayed on the right side of the corresponding route.

That is, first, the calculation unit 5 determines that the load unit of the branch pipe connecting each sanitary device and the main pipe is NPC (Natio).
According to the drainage load unit method according to the nal plumbing code), it is determined by the drainage load unit preset for each sanitary equipment. FIG. 8 shows a drainage load unit corresponding to each sanitary device. Further, FIG. 9 shows the (pipe diameter) caliber corresponding to the drainage load unit shown in FIG.

For example, as shown in FIG.
2, 23, and the path of the branch pipe of the washbasin 24,
A cleaning port 28, which is the upstream end of the path 21 of the drain horizontal branch pipe
Therefore, when they are arranged in this order, the branch pipe path 25,
The drainage load units at 26 and 27 are 4, 4, and 1 from FIG. 8, respectively. At this time, the pipe diameters corresponding to this drainage load unit are 50A, 50A, and 30A, respectively, as shown in FIG.

Next, the calculation unit 5 calculates the drainage load unit of the path 21a of the drain horizontal branch pipe between the confluence points P1 and P2.
In the present case, the toilet bowl 22 is provided upstream of the branch pipe path 21a.
Since the path 25 of the branch pipe from No. 4 merges, the drainage load unit of the path 21a of the branch pipe is 4. Therefore, FIG.
As a result, the diameter of the drainage pipe to be provided in the branch pipe path 21a is determined to be 50A corresponding to the drainage load unit 4.

A branch pipe path 25 and a branch pipe path 26 join upstream of the drainage horizontal branch pipe path 21b between the joining points P2 and P3. Therefore, the drainage load unit of each branch pipe is sequentially added from the upstream side by the calculation unit 5, and the total value is set as the drainage load unit of the branch pipe path 21b. In the present case,
Since the drainage load units of the branch pipe route 25 and the branch pipe route 26 are 4, respectively, 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 drainage pipe to be provided in the branch pipe path 21b is determined to be 65A corresponding to the drainage load unit 8.

Further, since the branch pipe paths 25 to 27 are joined upstream of the drainage horizontal branch pipe path 21c disposed downstream of the confluence point P3, the calculating unit 5 causes the branch pipe path 25 to flow. The drainage load units of Nos. 27 to 27 are summed up, and the total value is set as the drainage load unit of the branch pipe path 21c. In the present case, the drainage load unit of the branch pipe route 25 and the branch pipe route 26 is 4 respectively, and the drainage load unit of the branch pipe route 27 is 1. Therefore, the total value 9 obtained by adding them is It is set as a drainage load unit of the pipe path 21c. Therefore, from FIG. 9, the diameter of the drainage pipe to be provided in the branch pipe path 21c is set to 65 A corresponding to the drainage load unit 9.

Next, the processing unit 4 determines whether or not there is a path in which a member (drain 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 in which a member having the diameter determined by the calculation unit 5 cannot be generated or a path in which members overlap each other, an error is displayed on the screen of the display unit 1.

Next, in step S46, as shown in FIG. 11, the processing unit 4 generates a pipe member. That is, the drain pipe 1 having the diameter determined in step S45
11a to 111i and their corresponding joints 11
a and 11b are displayed at corresponding positions on the screen.

For example, when the sanitary equipments are arranged as shown in FIG. 10, first, at the confluence points P1 to P3 in FIG. 10, the drainage to be generated in each path calculated in step S45. A joint having a diameter corresponding to the path of the pipe is read from the storage unit 3 by the processing unit 4.

For example, at the confluence point P2, a joint 31 having a shape as shown in FIG. 12, three core wires 31a to 31c and paths 21a, 21b and 26 of branch pipes are connected at connection points 31d to 31f. They are arranged so that they overlap.

Next, by the processing unit 4, between the connection points connecting the sanitary equipment and the joints, or between the connection points connecting the joints,
A drain pipe (not shown) having the diameter determined in step S45 is generated. For example, when the distance between the sanitary devices is changed, these drain pipes can be expanded and contracted in response to the change.

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 where the members overlap each other.

When the generation and display of the drainage pipe and the joint are completed, the processing unit 4 causes the branch pipe path from the sanitary equipment (in this case, the toilet bowl 22) arranged in the uppermost stream, as shown in FIG. Point P where 25 joins route 21 of the horizontal drain pipe
On the extension line of 1, the pipes 42 and 43, the elbow 41, and the cleaning port 2 which are located at a position apart from the toilet bowl 22 by a predetermined distance and have the same diameter as the diameter of the drainage pipe at the confluence P1.
8 is arranged and displayed on the display unit 1, and the process ends.

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 including a mouse or a tablet. At this time, it is possible to arrange only one water supply device or a plurality of water supply devices.

Next, in step S54, as shown in FIG. 16, the input setting section 2 including, for example, a mouse or a tablet is used to specify two points on the screen of the display section 1 to The route 16c of the main pipe is created and displayed. When the main route 16c is displayed on the screen,
Based on the water supply equipment connection withdrawal distances a and b and the withdrawal direction set on the sizing screen shown in FIG. 4, the water supply equipment and the branch pipe paths 16a and 16b between the main pipes are determined by the processing unit 4. Displayed on the screen.

When it is determined that the route 16c of the main pipe set by the input setting unit 2 includes an unnecessary route, the processing unit 4 displays a screen asking whether the route should be deleted. , Are displayed on the display unit 1. The user can delete the route by designating to delete the route on this screen.

Next, in step S55, the user
Use the four-button cursor on the tablet or the mouse to indicate the downstream or upstream side and specify the flow direction. Next, the diameter of the water supply pipe to be routed to the route set by the input setting unit 2 and the route determined by the processing unit 4 is calculated by the calculation unit 5, and, for example, as shown in FIG. Characters representing the aperture calculated by the unit 5 are displayed on the right side of the corresponding route.

FIG. 18 is a diagram showing a procedure for determining the pipe diameter of the water supply pipe in the processing section 4. First, in step S61, the processing unit 4 causes the input setting unit 2 to
Table showing the relationship between each water supply device and the diameter of the connection pipe connected to each water supply device, which is stored in advance in the storage unit 3 (FIG. 19).
The diameter of the connection pipe of each device (water supply device) is set from the information corresponding to.

For example, as shown in FIG. 20, a hand washing device 5
When the 1, 52, the urinal 53, and the urinal 54 are arranged in this order, the connection pipe diameters of the handwashers 51, 52, the urinal 53, and the urinal 54 are calculated from the table shown in FIG.
13, 13, 13, and 25 respectively (in this case,
It is a cleaning valve). Therefore, the processing unit 4 sets the diameters of these connection pipes.

Next, in step S62, the processing unit 4
Is an equalization table showing the relationship between the connection pipe diameters of the water supply devices stored in advance in the storage unit 3 by the input setting unit 2 and the uniform number when the pipe diameter is converted to 13 (FIG. 21). ), The equal number of each device is determined. In the present 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 numbers of the hand wash devices 51 and 52 are 1 respectively. Is.

Next, in step S63, each section A,
The cumulative number of equal numbers in B or C is calculated. In the section A, the uniform number of the toilet bowl 54 is 5.6,
In the section B, the cumulative value 8.7 of the uniform numbers of the urinal 54 and the urinal 53 is calculated, and in the section C, the uniform number 5.6 of the urinal 54 and the even number of the urinal 53 are calculated. 3.1, the cumulative value of the uniform number 1 of the hand washing device 51 and the uniform number 1 of the hand washing device 52 is calculated for each type of device (toilet bowl and general appliance). From the table shown in FIG. 23, since the urinal 53 and the handwashers 51 and 52 are general appliances and the number of these appliances is 3, the simultaneous usage rate is 70%.

Next, in step S64, the arithmetic unit 5 multiplies the cumulative number of equal numbers in each section by the simultaneous usage rate shown in FIG. 23, and considers the simultaneous usage rate. The calculated uniform number is calculated.

In this case, the equal number considering the simultaneous usage rate of the section A is 5.6, and the equal number considering the simultaneous usage rate of the section B is 8.7. Further, the equal number in consideration of the simultaneous usage rate of the section C is 5.6, which is obtained by multiplying the equal number of the toilet bowl 54 by the simultaneous usage rate of 1.0, and the equal number of the urinal 53 is 3.1. , An equal number of handwashers 51, and a handwasher 5
The value 5.1 obtained by adding the even number 1 of 2 to the value of 3
Value obtained by multiplying the simultaneous usage rate of one device by 0.7 3.5
The value obtained by adding 7 is 9.17.

Next, in step S65, the processing unit 4
Thus, from the information corresponding to the equalization table (FIG. 21) stored in the storage unit 3, the connection diameter corresponding to the value of the equal number in consideration of the simultaneous usage rate calculated in each of the sections A to C is determined. In this case, the uniform number in consideration of the simultaneous usage rate in the section A is 5.6, and the diameter of the connecting pipe corresponding to it is set to 25 from the uniform table shown in FIG. Further, the equal number considering the simultaneous usage rate in the section B is
8.7, and the diameter of the corresponding connection pipe is shown in FIG.
It is set to 30 from the equivalence table shown in. Furthermore, the equal number considering the simultaneous usage rate in section C is 9.17,
The corresponding diameter of the connecting pipe is set to 30 from the uniform table shown in FIG.

In this way, the processing section 4 can determine the diameter of the connecting pipe in each section.

Next, the processing section 4 determines whether or not there is a path in which a member (water supply pipe or joint) having the diameter determined by the calculation section 5 cannot be generated or a path where the members overlap each other, and the calculation is performed. When there is a path in which a member having a diameter determined by the part 5 cannot be generated or a path in which members overlap with each other,
An error is displayed on the screen of the display unit 1.

Next, step S in the flowchart of FIG.
Proceeding to 56, as shown in FIG. 25, a pipe member is generated by the processing unit 4. That is, the water supply pipes 251a to 251i having the caliber determined in step S55 and the corresponding joints 25a to 25f having the shape shown in FIG. 26, for example, are displayed at corresponding positions on the screen of the display unit 1. To be done.

As shown in FIG. 20, in the case where each device is arranged and the route of the pipe is set, first, at each of the merging points P11 to P12 in FIG. 20, in each route calculated in step S55. A joint having a diameter corresponding to the path of the water supply pipe to be generated is read from the storage unit 3 by the processing unit 4.

For example, at the confluence point P11, a joint 61 having a shape as shown in FIG. 26, three core wires 61a to 61c and branch pipe paths 55a, 55b and 57 are connected at connection points 61d to 61f, respectively. They are arranged so that they overlap.

Next, the processing unit 4 generates a water supply pipe (not shown) having the diameter determined in step S55 between the connection points of each water supply device and the joint, or between the connection points of the joints. It For example, when there is a change in the distance between the water supply devices, these water supply pipes can be expanded and contracted in response to the change.

Further, at this time, the processing section 4 executes the step S
When there is a portion where the member having the diameter determined in 55 cannot be generated or where the members overlap each other, an error is displayed on the screen of the display unit 1.

In step S56, when the processing unit 4 displays a pipe member having a predetermined diameter on the display unit 1, the process ends.

Next, the operation of the ventilation pipe design display device to which the pipe 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 the drainage pipe design display device shown in FIG. First, in step S71, the piping mode is set. In this case, set the vent pipe mode. Next, step S72.
Proceed to.

In step S72, the drainage pipe design 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 will be omitted.

Next, in step S73, as shown in FIG. 28, the input setting section 2 including, for example, a mouse or a tablet is used to specify two points on the screen of the display section 1 to The route 28a of the main pipe is created and displayed.

When it is determined that the route 28a of the main pipe set by the input setting unit 2 includes an unnecessary route, the processing unit 4 displays a screen asking whether the route should be deleted. , Are displayed on the display unit 1. The user can delete the route by designating to delete the route on this screen.

Next, in step S74, the diameter (pipe diameter) of the ventilation pipe to be piped in the route set by the input setting unit 2 is calculated by the calculation unit 5, for example, as shown in FIG.
As shown in, the character (25A in this case) indicating the aperture calculated by the calculator 5 is displayed on the right side of the path of the corresponding ventilation pipe.

Next, referring to the flow chart of FIG. 30, the drainage pipes 31a to 31d are connected, for example, by the route as shown in FIG. 31, and further, the sanitary equipment is installed at predetermined positions of the drainage pipes 31b to 31d. If connected, a method of determining the pipe diameter of the ventilation pipes installed in these drain pipes will be described.

In FIG. 31, in the main pipe path 31a,
The three branch pipe paths 31b, 31c, and 31d are connected to each other, and the toilet pipes 71 to 74 are connected to the branch pipe path 31b.
A cleaning sink 71 is connected. In addition, route 3 of the branch pipe
Washbasins 75 to 77 are connected to 1c. Further, urinals 78 to 80 are connected to the path 31d of the branch pipe. In addition, it is assumed that the ventilation pipe paths 31e to 31h and 31k are set in step S73.

First, in step S81, the input setting unit 2 causes the ventilation pipes 31e to 31h and 31k.
Designate the equipment that the ventilation pipe that is to be routed to the ventilation pipe shown in (4) will be responsible for. Normally, it is in charge of ventilation of equipment connected by a single drain pipe. Therefore, for example, the ventilation of the sanitary equipment 71 to 74 is designated so that the ventilation pipe to be installed in the passage 31e of the ventilation pipe is responsible. Further, the ventilation of the sanitary equipments 75 to 77 is designated so that the ventilation pipe to be installed in the passage 31f of the ventilation pipe takes charge. further,
The ventilation of the sanitary equipment 78 to 80 is designated by the ventilation pipe to be installed in the passage 31g of the ventilation pipe.

Next, in step S82, the total value of the drainage load unit numbers 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
Reads out the drainage load unit of the sanitary equipment connected to each path of the ventilation pipe from the storage unit, adds them by the calculation unit 5, and calculates the drainage load unit of each path of the ventilation pipe. . For example, the sum of the drainage load units in the path 31e of the ventilation pipe is 8 for the drainage load units of the three toilets, and 2.5 for the drainage unit of the cleaning sink, so add them. Value obtained by 26.5 (= 8
X3 + 2.5).

Vent pipe paths 31f to 31h and 3
The same calculation method can be applied to 1k. That is, the drainage load unit of the ventilation pipe 31f is set to the value 3,
The value of the drainage load unit of the ventilation pipe 31g is 12, and
The drainage load unit of the ventilation pipe 31h is set to a value 15 obtained by adding the drainage load units of the ventilation pipe 31f and the ventilation pipe 31g.

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.

Next, in step S83, if there is a confluence of the ventilation pipes, the longer horizontal distance to the confluence is calculated. For example, the horizontal length of the ventilation pipe 31h is equal to the length of the ventilation pipe 31h, and the ventilation pipe 31f and the ventilation pipe 3 are
The value 7.5 is obtained by adding the longer length of 1 g. Similarly, the horizontal length of the ventilation pipe 31k is a value obtained by adding the length of the ventilation pipe 31e having the longest length to the confluence 13
It is said.

Next, in steps S84 to S85, the pipe diameter of each ventilation pipe is calculated. Since the length of the ventilation pipe 31e in the horizontal direction (maximum allowable lateral running pipe length) is 10 meters, the drainage load unit is 26.5 or more in the table shown in FIG. Is more than 10 meters, the diameter of ventilation pipe 31e is 65A
It is said. Similarly, in the drainage load unit of the ventilation pipe 31f, since the horizontal length of the ventilation pipe 31f is 3.5 meters, 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 diameter of the ventilation pipe 31f is 40A.

Similarly, since the length of the ventilation pipe 31g in the horizontal direction is 3.2 meters, the drainage load unit is 12 or more and the length in the horizontal direction in the table shown in FIG. 107. Is more than 3.2 meters, the 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, which is equal to the horizontal length of the ventilation pipe 31f and the ventilation pipe 31g joined to 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 m) is 7.5 m, in the table of FIG. 107, the drainage load unit is 15 or more, and the level is horizontal. This is applicable when the length in the direction is 7.5 meters or more, and the diameter of the ventilation pipe 31h is 50A.

Similarly, the drainage load unit of the ventilation pipe 31k is, as described above, among the ventilation pipes that join the ventilation pipe 31k within the horizontal length of 3 meters of the ventilation pipe 31k.
The longest distance in the horizontal direction, that is, the value obtained by adding 10 meters in the horizontal direction of the ventilation pipe 31e is 13 meters, so in the table of FIG. 107, the drainage load unit is 41.5.
The above is applicable when the horizontal length is 13 meters or more, and the diameter of the ventilation pipe 31k is set to 75A.

In this way, the ventilation pipes 31e to 31e
The tube diameters of h and 31k can be determined.

Next, the processing section 4 determines whether or not there is a path in which a member (ventilation pipe or joint) having the diameter determined by the calculation section 5 cannot be generated or a path in which the members overlap each other, and the calculation is performed. When there is a path in which a member having a diameter determined by the unit 5 cannot be generated or a path in which members overlap each other, an error display is displayed on the screen of the display unit 1.

Next, proceeding to step S75, as shown in FIG. 32, the processing section 4 generates a pipe member. That is, the ventilation pipe having the diameter determined in step S74,
And a joint having a shape corresponding thereto is displayed at a corresponding position on the screen of the display unit 1.

That is, the joints 32a and 32b having the caliber corresponding to the path of the ventilation pipe to be generated in each path calculated in step S74 are read from the storage section 3 by the processing section 4. Then, the read joint is arranged on the screen so that the three core wires and the paths of the branch pipes overlap each other at the connection points.

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. These ventilation pipes can be expanded and contracted in response to a change in the distance between the joints, for example.

At this time, the processing unit 4 displays an error on the screen of the display unit 1 when there is a place where the members cannot be generated or a place where the members overlap each other.

In step S75, when the processing section 4 displays a pipe member having a predetermined diameter on the display section 1, the processing is ended.

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 has basically the same structure as the drainage pipe design display device shown in FIG. First, in step S91, the piping mode is set. In this case, set the mode of air conditioning piping. Then, the process proceeds to step S92.

In step S92, a sizing setting screen such as that shown in FIG. 4 is displayed on the display unit 1, so that a predetermined column (in the case of air conditioning piping, a common column and an air conditioning column) is displayed in this screen. The sizing setting is performed by operating the input setting unit 2 including a mouse, a tablet, or a keyboard to input or select predetermined items. That is, first, the air conditioner withdrawal distance a is set. When air conditioners are arranged as described later and are connected to the main pipe at a predetermined distance from the arranged air conditioners, the distance a

Next, the arrangement method of the column of air conditioning is selected.
That is, the method of generating the core wire of the return path is a direct return as shown in FIG. 34 (a piping method not aiming to make the flow rate at the inlet and the outlet uniform) or a reverse return as shown in FIG. (Piping method that can make the flow rate at the inlet and outlet almost uniform) is selected.

Next, either the horizontal direction or the vertical direction is designated as the arrangement direction of the return path, and further, whether or not the gate valve is automatically created is selected.

Next, in step S93, air conditioning equipment is 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 including a mouse or a tablet. At this time, it is possible to arrange only one air conditioner or a plurality of air conditioners. In the present case, air conditioning equipment 3
6a and 36b are arranged.

Next, in step S94, as shown in FIG. 37, two points on the screen of the display unit 1 are designated by the input setting unit 2 which is, for example, a mouse or a tablet, so that the screen is displayed. Create a route 37c for the outward main pipe,
Display it. When the route 37c of the outward main pipe is displayed on the screen, based on the air-conditioning equipment connection withdrawal distances a and b set in the sizing screen shown in FIG. The branches 37a and 37b are determined by the processing unit 4 and displayed on the screen.

Further, when the processing unit 4 determines that the route 37c of the outward main pipe set by the input setting unit 2 includes an unnecessary route, the processing unit 4 inquires whether or not the route should be deleted. The screen is displayed on the display unit 1. The user
By specifying to delete the route on this screen, the route can be deleted.

Next, in step S95, the diameter of the air-conditioning pipe to be routed to the route set by the input setting unit 2 and the route determined by the processing unit 4 is calculated by the calculation unit 5
Is calculated by In the present case, the route 37 of the outward branch pipe
The diameters of the air-conditioning pipes to be routed to a and 37b are each 25A, and the diameter of the air-conditioning pipes to be routed to the path 37c of the outward main pipe is 50A. And, for example,
As shown in FIG. 38, the characters representing the aperture calculated by the calculator 5 are displayed on the right side or the upper side of the corresponding route.

Next, the processing section 4 judges whether or not there is a path in which a member having the diameter determined by the calculation section 5 (outgoing air-conditioning pipe or joint) cannot be generated, or a path where the members overlap each other. If there is a path in which a member having the diameter determined by the calculation unit 5 cannot be generated or a path in which members overlap each other, an error display is displayed on the screen of the display unit 1.

Next, in step S96, the processing unit 4
Is based on the route of the outward main pipe set in step S94, the air-conditioning arrangement method set in step S92, the return passage arrangement direction, and the presence / absence of automatic sluice valve creation. The route is determined, and the calculation unit 5 is caused to determine the diameter. The determined main route and branch route of the return route are displayed at predetermined positions on the screen of the display unit 1.

In the present case, the routes 39a, 3 of the branch pipe of the return route
9b and the route 39c of the main pipe of the return route are displayed as shown in FIG. 39, and the diameters of the air conditioning pipes to be routed to the routes 39a and 39b of the return route branch pipes are set to 25A, respectively.
The diameter of the air-conditioning pipe to be provided in the main pipe 39c of the return path is 50A.

Next, in step S97, for example, in FIG.
As shown in 0, 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 joint corresponding thereto are displayed at the corresponding positions on the screen of the display unit 1. Further, the reducer is displayed at the corresponding position on the screen of the display unit 1 in accordance with the reducer occurrence position set in step S92.

First, the processing unit 4 reads out from the storage unit 3 a joint having a diameter corresponding to the route of the air conditioning pipe to be generated in each route in the return route, which is calculated in steps S95 and S96.

For example, the joint 40a of FIG. 40 is arranged and displayed on the screen so that its two core wires overlap the paths 37a (FIG. 38) and 37c (FIG. 38) at their connection points, respectively. Similarly, the other joint 40b is arranged and displayed such that its three core wires overlap the paths 37b (Fig. 38) and 37c (Fig. 38) at their connection points, respectively. The same applies to the joints 40c to 40f.

Next, the processing unit 4 performs step S between the connection points of each air conditioner and the joint, or between the connection points of the joints.
95, the air-conditioning piping (401a to 401i) having the diameter determined in S96 is generated. These air conditioning pipes can be expanded and contracted in response to a change in the distance between the air conditioners, for example.

At this time, the processing unit 4 displays an error message on the screen of the display unit 1 when there is a route in which members cannot be generated or a route in which members overlap.

In step S97, when the processing section 4 displays a pipe member having a predetermined diameter on the display section 1, the processing is ended.

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 in FIG.

Next, by the processing unit 4, between the connection points of each sprinkler device and the joint, or between the connection points of the joints,
Sprinkler pipes 451a to 451g having the diameter determined in step S104 are generated. These sprinkler pipes 451a to 451g can be expanded and contracted in response to the change in the distance between the sprinkler devices, for example.

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 members cannot be generated or a portion where the members overlap each other.

In step S105, when the processing unit 4 displays a pipe member having a predetermined diameter on the display unit 1, the process ends.

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 in FIG. The configuration of the fire hydrant piping design display device has basically the same structure as the drainage pipe design display device shown in FIG. At first,

When the user wants to delete the route, if the user instructs to delete the route on this screen, the processing unit 4 deletes the route.

Next, proceeding to step S114, the user first designates the downstream side (or upstream side) using the four-button cursor of the tablet or the mouse to specify the flow direction. Next, the diameter of the fire hydrant piping to be routed to the route set by the input setting unit 2 and the route determined by the processing unit 4 is calculated by the calculation unit 5. In this case, the diameter of the fire hydrant piping to be routed in the branch pipe path 48b is 40A, and the diameter of the fire hydrant piping to be routed in the main path 48a is 40A. Then, as shown in FIG. 49, for example, a character representing the aperture calculated by the calculator 5 is displayed on the right side or the upper side of the corresponding path.

Next, the processing unit 4 determines whether or not 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, and the calculation is performed. When there is a path in which a member having a diameter determined by the unit 5 cannot be generated or a path in which members overlap each other, an error display is displayed on the screen of the display unit 1.

Next, in step S115, the processing section 4 generates a pipe member, for example, as shown in FIG. That is, the fire hydrant pipe having the caliber determined in step S114 and the joint corresponding thereto are displayed at the corresponding positions on the screen of the display unit 1.

That is, first, the processing unit 4 reads from the storage unit 3 the outline drawing of the joint having the diameter corresponding to the fire hydrant piping to be generated in each route, which is calculated in step S114.

For example, in the joint 50a shown in FIG. 50, two core wires thereof have paths 48b (FIG. 48) and 48c (FIG. 4).
8) and the connection points are arranged and displayed on the screen so as to overlap each other. Similarly, the joint 50b has two core wires whose paths 48a (Fig. 48) and 48b (Fig. 48).
And are arranged and displayed so as to overlap each other at the connection points.

Next, the processing section 4 generates 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) can be expanded and contracted in response to the change in the distance between the fire hydrant devices, for example.

Further, 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 members cannot be generated or a portion where the members overlap each other.

Next, in step S116, the pipe pressure loss calculation of the pipes created in steps S111 to S115, that is, the resistance value received when water flows through the pipe is calculated, and the pipe head calculation, that is, , When the water is supplied to the pipe by the predetermined pump, the ability to show how many meters of water and how many liters of water can be lifted is calculated, and the process ends.

The above-described pipe pressure loss calculation and pipe head calculation in step S116 are not limited to fire hydrant pipes, and can be similarly performed for drain pipes, water supply pipes, ventilation pipes, air conditioning pipes, or sprinkler pipes. it can.

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 structure of the duct design display device is

According to the set face-to-face heights (lower surface, upper surface, center), the shapes of the elbow, hopper, runout hopper, 2-way branch (1), 2-way branch (2), and 3-way branch are shown in FIG. Each is transformed as shown in.

On the duct specification content display setting screen shown in FIG. 57, as described above, when it is desired to cancel the setting of the specification item while setting the specification item, the input setting section 2 is operated to By designating the selection item “Cancel” displayed on the upper right of the screen, each specification item (duct attribute) is not changed, and the duct specification list display screen shown in FIG. 52 is displayed.

In the duct specification content display setting screen shown in FIG. 57, when it is desired to confirm the specification content currently displayed or selected, the input setting section 2 is operated to select the selection item "upper right" on the screen. Confirm ”command. As a result, the currently displayed specifications are confirmed. Then, the duct specification list display screen shown in FIG. 52 is displayed.

Next, in step S122, the duct dimensions are set. First, the processing unit 4 displays a duct size calculation method selection screen as shown in FIG. 64 on the display unit 1. On this screen, operate the input setting unit 2 to instruct the selection item "total pressure method" when selecting the total pressure method as the calculation method, and select the selection item "constant speed method when selecting the constant velocity method as the calculation method. To indicate. If you do not want to calculate the dimensions, specify "No calculation".

When the total pressure method is selected, the value set as the friction loss is valid and is used for the size calculation. When changing the value of this 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 valid and is used for the dimension calculation. When changing the value of the wind speed, the input setting unit 2 is operated to input a predetermined value.

As the dimensional standard, one of the selection items “reference” or “not reference” is selected. When the selection item “Refer” 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 according to the standard.

When the setting on the duct size calculation method selection screen is completed, in the case of the rectangular duct specification, the processing unit 4 displays the condition setting screen for the rectangular duct specification as shown in FIG. It On this screen, by operating the input setting unit 2, the air volume at each connection point of the square duct is input, and then the dimension values of the ceiling (height) and the sleeve (width) are input as the duct dimensions. Then, by instructing either the selection item “heaven” or “case”, either the sky or the case is selected.

Next, the set value and the selection item are confirmed by instructing the selection item "confirmation", and the duct size is determined by the calculation unit 5 with reference to the dimension value of the one selected from the top or the sack. Is calculated.

In the case of the round duct specification, the processing section 4 displays a condition setting screen in the case of the round duct specification on the display section 1 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 “confirm” is instructed, the set air volume is confirmed.

When the total pressure method is selected on the screen of FIG. 64, the wind speed is calculated by the calculation unit 5 from the friction loss and the air volume input as the condition, as shown in FIG. The calculation result 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.

On the other hand, when the constant velocity method is selected on the screen of FIG. 64, the friction loss is calculated by the calculation unit 5 from the wind speed and the air volume input as the condition, as shown in FIG. The calculation result is displayed on the display unit 1. In this example, the friction loss at connection point 1 is 0.20, the friction loss at connection point 2 is 0.10, the friction loss at connection point 3 is 0.20, and the friction loss at connection point 4 is 0.30. .

Next, in step S123, member setting is performed. The processing unit 4 displays a member generation setting screen as shown in FIG. 69, for example. In this screen,
As will be described later with reference to FIG. 81, whether or not to make an inquiry at the time of automatic placement is selected by operating the input setting unit 2 and instructing the selection item “present” or “none”.

Next, only one member of the square duct and one member of the round duct which are arranged on the path line branched in two directions are selected. Similarly, only one each of the member of the square duct and the member of the round duct arranged on the route line branched in three directions is selected. Similarly, only one member of the corner duct to be arranged on the path line branched in four directions is selected. Further, in the case of a square duct, the device connected to the last outlet of the duct is selected. In the case of a round duct, only the devices shown here can be connected.

When the selection item "present" is selected on the screen shown in FIG. 69, an inquiry is made as to which member should be arranged for each member on the screen shown in FIG.
At this time, the member set in FIG. 69 is displayed as the initial value. Then, the input setting unit 2 is operated to select a desired member. On the other hand, when the selection item “none” is selected, no inquiry is made in FIG.
The members set in FIG. 69 are unconditionally arranged.

The processing up to this point is the processing required when the specifications, dimensions, members, etc. of the duct are set manually. Therefore, when making the apparatus perform all of these processes, steps S124 to S1 described below are performed.
Only 26 processes are performed.

In step S124, a route line is drawn. First, the processing unit 4 displays an application 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 is selected. Here, when the air conditioning path is selected, the path line is drawn as the path of the air conditioning duct. When the smoke exhaust path is selected, the path line is drawn as the path of the smoke exhaust duct.

Next, the route line of the air conditioning route or the smoke exhaust route selected in FIG. 70 is set. In this case, the air conditioning path is set. The display unit 1 displays an operand selection screen as shown in FIG. 71 by the processing unit 4. On this screen, the operands are "absolute", "relative", "line point", "line end point", "line intersection", "water drop", "rounding",
And "Device" are displayed. Operand "absolute"
If you select, the XY coordinate at the bottom left of the screen is the origin (0,
0) and inputting the XY coordinate values by operating the keyboard, it is possible to specify a predetermined position on the screen.

When the operand "relative" is selected, the XY coordinate at a predetermined position on the screen is used as the reference point, and the keyboard is operated to input the XY coordinate values relative to the reference point. The predetermined position of can be specified. When "point on line" is selected as the operand, the position on the screen manually specified using the four-button cursor is corrected to the position on the line that is already displayed on the screen in the vicinity thereof.

When the operand "line end point" is selected, the position on the screen manually designated by using the four button cursor is corrected to the position of the line end point which is already displayed on the screen in the vicinity thereof. When the operand "line intersection" is selected, the position on the screen manually specified using the four button cursor is corrected to the position of the line intersection already displayed on the screen in the vicinity of the position. When the operand "water drop" is selected, a vertical line drawn from the position on the screen manually specified using the four-button cursor to the line already displayed on the screen in the vicinity of the position is displayed.

When the operand "round" is selected and the predetermined position on the screen is manually designated using the four-button cursor, the cursor displayed on the screen moves in units of a predetermined number of dots on the screen. For example, it moves in units of 50 dots or 100 dots. 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 which is already displayed on the screen in the vicinity thereof.

From the above-mentioned operands, for example, the operand "round" is selected, and as shown in FIG. 72, the four button cursor of, for example, the tablet constituting the input setting section 2 is operated to display it on the screen. The starting point 72a is designated by moving the cursor to the starting point 72a and clicking the upper button of the four button cursor.

Next, the cursor is moved to the passing point 72a, and the upper button of the four button cursor is clicked to indicate the passing point 72a. 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 fixed. When the end point is determined, the route indicated by the plurality of passing points and displayed by the solid line is displayed by the one-dot chain line as shown in FIG. 73. In this way, the route line can be drawn.

As described above, by selecting the "round" operand, the cursor moves on the screen by a predetermined number of dots, for example, a unit of 50 or 100 dots. With this, it is possible to easily specify a horizontal or vertical line with respect to the screen by manual operation. Further, at this time, the designated passing point may be corrected and displayed in the horizontal, vertical, or 45 ° direction.

Next, in step S125, the diameter of each part of the route line drawn in step S124 is calculated. First, the processing unit 4 displays a duct type selection screen as shown in FIG. 74 on the display unit 1. 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 as a square duct. On the other hand, when the circle is selected, the calculation unit 5
Thus, the diameter is calculated as a round duct.

Next, the processing section 4 displays a message "Please indicate the most upstream core wire of the main pipe" as shown in FIG. 75 on the display section 1, so operate the input setting section 2. , A predetermined position 76a on the most upstream route line of the route line shown in FIG. As a result, the processing unit 4 displays the arrow indicating the flow direction in the route direction on the designated route line, and also displays the message “Is this direction?” As shown in FIG.

When the direction of the arrow displayed in FIG. 76 is the same as the flow direction, the "Y" key is input by the keyboard constituting the input setting unit 2 or the left button of the four button cursor of the tablet is pressed. click. This establishes the flow direction. On the other hand, if the direction of the arrow displayed in FIG. 76 is the direction opposite to the flow direction, the "N" key is input with the keyboard configuring the input setting unit 2 or the right button of the four button cursor is clicked.
As a result, the direction of the arrow displayed in FIG. 76 is reversed, and the message shown in FIG. 77 is displayed again on the display unit 1. After that, the same operation as that described above is repeated.

When the "Y" key is input on the screen of the screen of FIG. 77 or the left button of the four-button cursor is clicked and the flow direction is confirmed, the processing section 4 displays the flow direction as shown in FIG. The message “Please set the value of the chest” is displayed on the display unit 1. Here, by operating the input setting unit 2, the value of the duct fold is input and set. In this case, for example, the value 10
Set to 0.

[0200] When the value of the seed is input, the arithmetic unit 5
The caliber (in the case of a round duct) or the top and bottom (in the case of a square duct) and the height of each part of the route line shown in FIG. 76 are calculated, and the calculation result is shown on each route line as shown in FIG. 79. Is displayed in the corresponding part of.

Next, in step S126, the duct members and the like are automatically arranged. The processing unit 4 displays the route line on the display unit 1 as shown in FIG. On this screen, the input setting unit 2 is operated to indicate a predetermined position 80a on the route line for which the aperture calculation has been performed, thereby instructing a predetermined route line. At this time, in the case where “Yes” is selected as the inquiry at the time of member occurrence in FIG. 69, the processing unit 4 makes an inquiry of that type on the route line indicated on this screen in FIG. 80. The display color of the portion where the component to be placed is changed, and a selection window for selecting the component that can be placed in that portion is displayed in the upper right portion of the screen. FIG.
Reference numeral 1 denotes a screen on which this selection window is displayed. 82 is a diagram showing the selection window displayed in the upper right of FIG. 81. In this case, two types of elbows for the square duct are displayed.

In the selection window shown in FIG. 82,
When the input setting unit 2 is operated, 2 displayed as the member type
By selecting one of the two members, the selected member is placed at a predetermined position on the path. in this case,
The elbow is placed in place. Similarly, a device that can be placed in another portion on the route is selected and placed in a predetermined position.

Next, when arranging the outlets, the distance between the height of the route line and the height at which the outlets should be installed is determined by the set neck length, that is, from the route line downwards. Processing unit 4 when the distance is different from
As a result, as shown in FIG. 83, the message "Change neck length to route line height. Continue processing?" Is displayed on the display unit 1. This is to inquire 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.

To continue the processing, the "Y" key is input from the keyboard constituting the input setting section 2 or the left button of the four button cursor of the tablet is clicked. On the other hand, if you want to cancel the process, press "N" from the keyboard.
Enter the key or click the right button of the four button cursor.

Enter the "Y" key from the keyboard or
Alternatively, when the left button of the four-button cursor of the tablet is clicked, the neck length is changed to the height of the route line by the processing unit 4, and then the blowing outlet is arranged and displayed at a predetermined position, and the processing ends.

Further, in the above-described embodiment, a predetermined range on the path where the ceiling and the shoulder are calculated is designated as a square duct by operating the four button cursor of the tablet, and only that portion is designated as a circular duct and its diameter is set. It is possible to make it recalculate. On the contrary, first, specify the predetermined range on the path whose diameter was calculated as a circular duct by operating the four-button cursor, and make only that part a square duct to recalculate its heaven and sword. 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.

In the case of a square duct, it is possible to specify a predetermined portion on the route by operating the four button cursor and change only the width of that portion. At this time, the height is recalculated by the constant pressure method. In the case of a square duct,
It is also possible to determine the size of the heaven and the case according to a predetermined standard size group (Ministry of Construction specifications, Air Conditioning Sanitation Engineering specifications, etc.).

Furthermore, in the part where the route branches,
It is also possible for the processing unit 4 to display the branched portion on the display unit 1 by the branching method set in advance. As a result, even a CAD operator who does not have specialized knowledge can easily and quickly design and draw a duct.

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. 1, and therefore its illustration and description are omitted.

First, in step S131, the connected device is placed at a predetermined position on the screen. Next, the process proceeds to step S132 to set the route drawing. Since the processing unit 4 displays a sizing setting screen as shown in FIG. 86 on the display unit 1, for example, in a predetermined column (in the case of air conditioning water piping, a common column and an air conditioning column), a mouse, By operating the input setting unit 2 consisting of a tablet or a keyboard to input or select predetermined items,
Make sizing settings. That is, first, the air conditioner withdrawal 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, it is necessary to set the distance a.

Next, selection of the drawing direction, that is, 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 is connected to the main pipe through the left side of the air conditioner. Or select. Next, the pull-out distance b of the air conditioner is set. Further, when arranging reducers having different sizes of the inlet and the outlet, the distance c between the reducer 4a and the adjacent component is input.

Next, the arrangement method of the column of air conditioning is selected.
That is, the method for generating the core wire of the return path is a direct return as shown in FIG. 34 (a piping method which is not intended to make the flow rate at the inlet and the outlet uniform), or a reverse as shown in FIG. Select whether to use return (a piping method that can make the flow rate at the inlet and outlet almost uniform). Next, when the return route is automatically generated in parallel to the forward route, the designation of whether to arrange the return route in the horizontal direction or in the vertical direction is performed as the forward route setting direction, either the horizontal direction or the vertical direction. This is done by specifying When reverse return is selected as the arrangement method, the folding direction is also determined according to this arrangement direction.

Further, whether or not to automatically create the sluice valve is selected by selecting "Yes" or "No".
When "Yes" (automatic creation) is selected, a sluice valve is automatically generated on the branch pipe between the main pipe of the drawn route line and the device (fan coil). At this time, the sluice valve is generated at the center of the branch pipe closest to the main pipe.

Next, in step S133, the processing section 4 displays a usage selection screen, for example, as shown in FIG. 87 on the display section 1. Therefore, by operating the input setting section 2, the corresponding usage is selected. . In this case, since it is the outward route of the conditioned water pipe, the air conditioning route (forward) is selected.

Next, the input setting section 2 is operated to draw a path of the conditioned water pipe. For example, the four-button cursor of the tablet is operated to move the cursor displayed on the display unit 1 to a predetermined position, and the upper button is clicked there, thereby instructing the start point. Next, the cursor is moved to another predetermined position and the up button is clicked to indicate the passing point. By repeating the same operation, a plurality of passing points are designated, a predetermined route is drawn, and finally, by clicking the left button of the four-button cursor, the end point is designated and the route is fixed. In this way, a predetermined route can be drawn.

When the drawing of the route is completed, the procedure goes to step S135 to set the conditions for the aperture calculation.
The processing unit 4 displays a system list screen as shown in FIG. 88 on the display unit 1, so that the material of the pipe for which the diameter is to be calculated is selected. The system name is the file name of the system master file. In this master file, information about pipe materials and fitting files is recorded, and the straight pipes and parts can be arranged by referring to these. It is possible. In this case, the fourth system name is selected.
Thereby, referring to the pipe material and joint file recorded in the system master file indicated by this system name,
Arrangement of straight pipes and parts described later is performed.

Next, the input setting unit 2 is operated to instruct the route line for the aperture calculation. Here, a method of instructing a route line will be described using an example of a water supply pipe, but the same applies to the case of conditioned water pipes. 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 designated. Thereby, the route line can be designated.

Next, as shown in FIG. 90, the most upstream or the most downstream on the route line is designated according to the intended use of the route line. In the case of water supply pipes, hot water supply pipes, air conditioning pipes (outward), sprinklers, and fire hydrants, the highest order is indicated, and in the case of sewage pipes, miscellaneous drainage pipes, ventilation pipes, and air conditioning pipes (return route),
Indicate the most downstream. In this case, since it is the air-conditioning water pipe (outward route), the predetermined position 90a on the uppermost flow line is designated as in the case of the air-conditioning pipe (outward route).

Next, as shown in FIG. 90, the flow direction is indicated by an arrow, and as shown in FIG. 91, the message "Is this direction?" Is displayed on the screen. When the flow direction is the direction specified by the arrow, the input setting unit 2
Enter the “Y” key on the keyboard that composes, or click the left button of the four-button cursor on the tablet. This establishes the flow direction.

On the other hand, in FIG. 90, when the flow direction is not the direction indicated by the arrow, the "N" key of the keyboard is input or the right button of the four button cursor of the tablet is clicked. As a result, a reverse arrow is displayed on the screen, and this flow direction can be instructed and confirmed.

Next, the connected device is instructed. Here, the case of calculating the diameter of the ventilation path will be described as an example.
The same applies to the outward route of the conditioned water pipe. First, the processing unit 4 displays a screen as shown in FIG. Here the ventilation paths are indicated by the dotted lines,
The drainage route is indicated by a dashed line. Here, for example, the route line of the branch portion where the ventilation route and the drainage route branch are displayed in red in order.

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 designating positions 93a and 93b, a rectangular area having the positions 93a and 93b as vertices is set. As a result, the devices in this rectangle are connected to the ventilation path 92 of FIG.
It can be designated as a device that a is in charge of.

When the device which the ventilation path 92a is responsible for is set, the ventilation path 92b of FIG. 92 is displayed in red next. Therefore, in the same manner as described above, the device which the ventilation path 92b is responsible for is designated. Similarly, the device designated by the ventilation path 92c in FIG. 92 is designated. In this way, the device to be connected to the predetermined route is designated.

When the condition setting for the aperture calculation is completed in this way, the operation proceeds to step S136, and the aperture of the route drawn in step 134 is calculated by the calculator 5 based on the set condition. 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 aperture in the vicinity of 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, the route A straight pipe corresponding to the above is generated and arranged at a predetermined position, and a component such as a joint having a corresponding diameter is generated and arranged at a predetermined position.

When the drawing of the outward route of the conditioned water pipe is completed in this way, next, the drawing of the return route of the conditioned water pipe is performed.

In step S141 of FIG. 85, the usage of the return route of the conditioned water pipe is selected. The application unit selection screen as shown in FIG. 94 is displayed on the display unit 1 by the processing unit 4. Therefore, by operating the input setting unit 2, the air conditioning path (return) is selected here.

Next, the processing unit 4 displays the device connection angle setting screen as shown in FIG. 95 on the display unit 1. Therefore, using the device as an operand, the device displayed in FIG. 96 is designated, Either 45 degrees or 90 degrees is selected for each device as the connection angle between the instructed device and the route. Here, 90 degrees is selected.

By using "device" as an operand in this way, the four button cursor of, for example, the tablet constituting the input setting section 2 is manually operated,
The cursor position is corrected to the target device position by simply moving the cursor displayed on the display unit 1 and specifying the vicinity of the specified device. Therefore, the device can display the cursor position easily and in a short time. It is possible to move it to the position.

Next, the operation proceeds to step S142, where the outbound route which has already been drawn and whose diameter has been calculated is instructed by operating the input setting section 2. Here, a predetermined position 96a on the outward route is designated.

Next, in step S143, the direction of arrangement of the return route is specified. That is, in the case where the horizontal direction is set as the forward and backward route arrangement direction set in FIG. 86,
The input setting unit 2 is operated to instruct the placement 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 in parallel with the forward route at a position displaced by a predetermined distance in the downward direction on the screen.

On the other hand, when the vertical direction is set as the direction of arrangement of the forward and backward routes set in FIG. 86, the processing unit 4 causes the display unit 1 to display the air conditioning route (return) drawing position setting screen as shown in FIG. Since it is displayed, the input setting unit 2 is operated to select whether to arrange the return route at a higher position or a lower position with respect to the forward route. For example, when the selection item “high” is selected, the return route is arranged in parallel with the forward route at a higher position. On the other hand, when the selection item "low" is selected, the return route is arranged in parallel with the lower route with respect to the forward route.

When the return route is arranged, the distance between the core of the pipe arranged on the forward route and the core of the pipe arranged on the return route is three times the diameter of each pipe. It is possible to arrange them at the above distance. As a result, even when the heat insulating material is attached around the conditioned water pipes arranged on the outward route and the return route, the conditioned water pipes may come into contact with each other or the pipes cannot be actually piped. Such a situation can be prevented.

Next, in step S144, the calculation unit 5 calculates the diameter of the return path. Then, the return route is automatically created based on the calculation result of the aperture calculation and the set value designated or selected in steps S141 to S143. FIG. 98 shows a screen in which a return route is automatically created. Here, an example is shown in which the aperture is not displayed for easy viewing.

In this way, the return route of the conditioned water pipe can be automatically operated.

[0235] Next, a method of routing the route line when connecting it to a device will be described. In the sizing setting screen shown in FIG. 99, the pull-out distance a and the pull-out distance b are set in advance. Further, the pull-out direction is selected to instruct whether the pull-out path should be output to the right side or the left side of the device. For example, when right is selected as the pull-out 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 connecting path.

When the device connection direction is toward the connection route, the pull-out distances a and b set in FIG. 99 are set.
The setting value of is invalid, and as shown in FIG. 101, the branch pipe path from the main pipe path to the device is set as a straight line without being routed.

Next, an example of the method of calculating the minimum interval between tubes will be described. When reverse return is instructed as the return route automatic creation and placement method, when the forward route pipe and the return route pipe are automatically created as shown in FIG. 102, the pipe placement distance L is as shown in FIG. It is possible to make a determination based on the pipe diameter according to a table in which the pipe diameter (nominal diameter) and the distance L between the pipes are associated with each other.

In each of the above embodiments, when the main pipe path is set, the branch pipe path between the connected device and the main pipe is determined by the processing unit 4. However, the user can select the branch pipe path. It is also possible to set. Also,
The user may set a part of the path of the branch pipe connected between the connected device and the main pipe.
