[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for interactively designing a support structure using a three-dimensional CAD, and more particularly, to optimize a pipe shape and a support structure to improve a plant appearance. The present invention relates to a method and an apparatus for designing a support structure, which can be considered and reduced in cost.

2. Description of the Related Art In recent years, a three-dimensional CAD, which has been remarkably developed, is used to design a planned product (supporting object) such as piping. After designing the piping, etc., next, find the mounting position for mounting the support structure (hanger) that supports the piping, etc., to the floor, wall, ceiling, etc.

Conventionally, after the piping design is completed, a piping design drawing (paper) and necessary materials are sent to the manufacturer, and the manufacturer designs the support structure according to the piping shape only for the piping. It was carried out, and it was a method of designing the supporting structure of each pipe at any time.

Further, since the shape of the support structure is designed based on the drawing of the pipe to be supported by the support structure, it depends only on the pipe. For this reason, the shape of the support structure has become complicated, and the cost has tended to increase.

With reference to FIG. 5, a conventional method for designing a pipe and a supporting structure will be described in detail.

As shown in step S101, first, a piping designer makes a piping plan (a piping route plan) on a three-dimensional CAD. Next, as shown in step S102, the piping designer decides only the model of the hanger and then calculates the heat of the piping system. Next, based on the result of the heat calculation, the piping designer makes a piping plan on three-dimensional CAD,
As shown in step S103, a comprehensive piping diagram is created. At this time, the piping system is corrected while checking the interference of the piping system. Based on the result, a detailed piping diagram is created as shown in step S104.

After that, as shown in step S105,
Hanger design (design of hanger shape) is performed based on the detailed piping diagram showing the temporary final state of piping design. In this case, design the actual hanger. Then, step S
As shown in 106, interference or the like is checked based on a hanger diagram showing a temporary final state of the hanger design.

As a result of the check in step S106,
If there is interference, the process returns to step S101 to correct the piping, the process returns to step S105 to correct the hanger, or both of them are corrected. Make that fix,
After performing the predetermined steps (S101 to S104), the check in step S106 is performed again, and if there is interference, the above correction is performed again. After that, step S106
As a result of the check, it was repeated until the interference disappeared.

FIG. 6 corresponds to the contents of the flowchart of FIG. 6, steps corresponding to those in FIG. 5 are designated by the same reference numerals as those in FIG.

Step S201 in FIG. 6 corresponds to steps S101 and S102 in FIG. 5, and shows that these steps S101 and S102 are performed on the three-dimensional CAD. As shown by reference numeral Y1, step S20
In No. 1, a part of the piping plan is corrected based on the result of the heat calculation and the interference check of the piping system. Step S
As a result of 201, as shown in steps S103 and S104, a comprehensive piping diagram and piping details (piping detail drawing) are created.

After step S104, step S105
The step S105 includes a hanger planning step S105a and a hanger detailed design step S1.
05b and a hanger device diagram creating step S105c. As indicated by reference numeral Y2, step S
In 105a and step S105b, the hanger design is partially modified. As a result, step S1
At 05c, a hanger device diagram is created.

After the hanger device drawing is created after step S105c, the interference between the pipe and the hanger is checked in step S106. As a result of step S106,
If the pipe and the hanger interfere with each other, step 201 and step S104 are performed again, step S105 is performed again, or step S104 and step S1.
After performing 05 again, step S106 is performed again. The same operation as described above is repeated until there is no interference as a result of step S106.

As a result of step S106, the periods until the interference disappears are the piping design period T1 and the hanger design period T2, respectively. Thereafter, while the piping is manufactured as shown in step S107, the hanger is manufactured as shown in step S108. After that, piping and hangers will be installed locally.

[0014]

The conventional design of a support structure is performed by a designer of a support structure (support device for supporting a pipe) (pipe support) which is completely different from a designer of a pipe or the like (plant maker). (Device maker) does this based on the piping drawings, and there were the following problems.

The shape of the support structure does not match the shape of the pipe or the like. Interference with other piping occurs frequently. It is difficult to correct the piping because the shape of the piping has been decided. Since the manufacturer selects the style of the support structure, the standard products are used less frequently. Since the support structure is designed after the pipe shape is determined (after the pipe design is completed), the design period is long, and frequent changes are made, resulting in a significant loss of time.

When such an event occurs, a rework work such as changing the shape of the support structure, returning to the initial plan, and redesigning the piping will occur. In such a situation, there is a problem that time loss increases. There are hundreds to thousands of pipes alone, and if each pipe is supported by dozens of supports, the number of supporting structures that must be designed becomes enormous and labor is increased.

Further, since the piping and the supporting structure have been designed separately, the aesthetics of the plant is secondary, and further, the design is made only for the supporting performance, so that the cost cannot be reflected. It was

Incidentally, Japanese Patent Laid-Open No. 6-89320 discloses that
The following three-dimensional CAD support data creation method is disclosed. The three-dimensional CAD support data creation method is the shape of the support structure that conforms to the design data of the plan at the designated point when the support attachment point of the plan is designated on the plan of the plan displayed on the screen. A pattern candidate is selected from the shape pattern data prepared in advance and displayed on the screen, and when one shape pattern is specified from the shape pattern candidates, the design of the designated shape pattern and the plan at the designated point The feature is that detailed data of the support structure at the designated point is automatically created from the data.

It is an object of the present invention to provide a supporting structure designing method and apparatus capable of solving the above problems.

Was realized. As a result, the total amount of material can be reduced by optimal design of piping and hangers.

[0029]

DETAILED DESCRIPTION OF THE INVENTION One embodiment of the present invention will be described.

A method of designing a support structure according to an embodiment will be described with reference to FIGS. 1 and 2.

In the present embodiment, when designing a support object such as a plant pipe, when designing a support structure for supporting the pipe, the support structure and the pipe are shaped so as to have mutually better shapes. By optimizing the design of the support structure, it aims to realize cost reductions.

The configuration of the present embodiment will be described with reference to FIG.

In FIG. 1, the piping plan in step S21a corresponds to the piping plan S201 in FIG.
The interference check in step 16 corresponds to the interference check in step S106. Further, the general piping diagram / pipe details of step S14 corresponds to the general piping diagram / pipe details of steps S103 and S104. Step S15
The hanger plan of a corresponds to the hanger plan of step S105a. The detailed hanger design in step S15b corresponds to the detailed hanger design in step S105b. The hanger device diagram of step S15c corresponds to the hanger device diagram of step S105c. The hanger production in step S18 corresponds to the hanger production in step S108. Pipe fabrication in step S17
It corresponds to the pipe fabrication in step S107.

The pipe design period T3 in FIG. 1 corresponds to the pipe design period T1 in FIG. The hanger design periods T4 and T5 correspond to the hanger design period T2.

When designing plant piping, three-dimensional CAD
(Step S21a), but at the same time, the supporting structure such as the piping is designed by three-dimensional CAD (Step S15a).

In this business method, the plant design is performed by the plant maker, and the support structure (pipe support device, hanger) is designed by the pipe support device maker. The hanger maker designs the pipe support device by three-dimensional CAD according to the piping (step S21a) designed and planned by the plant maker (step S15a).

Further, the planned design of the pipe support device (step S
By dividing labor between 15a) and detailed design (step S15b), it is possible to place an order after designating the style of the pipe support device determined in the planned design (step S15a).

In step S21 and step S15a which are executed in the three-dimensional CAD in cooperation with each other, the three-dimensional C is used in order to make the pipe support device according to the design condition of the piping system.
A shape pattern candidate registered in advance in the AD device is selected, dimensions of the support structure are automatically created according to each condition, and the shape of the support structure is displayed.

Thereafter, a comprehensive check of interference (step S16), cost, aesthetics, etc. is performed on the three-dimensional CAD (on the plant model), and the piping and pipe support device are designed to have the optimum shape.

In this embodiment, a three-dimensional CAD for plant piping design is used to perform a piping basic design (step S21a) and a pipe support device basic design (step S15a) on the model at the time of initial planning. A comprehensive check for interference and the like (S16) is performed. As a result, the following effects (1) to (5) can be obtained.

(1) It is possible to perform a sufficient study at the time of basic design, and it is possible to easily make a correction. (2) In addition, it is almost a support structure (hanger) during basic design.
Since the shape of is determined, it is possible to make inquiries to multiple manufacturers. (3) By performing the plant piping plan and the pipe supporting device plan at substantially the same time (steps S21a and S15a), the pipe supporting device plan can be completed early. In addition, the period of detailed design of the piping and the pipe support device can be greatly speeded up. (4) In step S15a, it is possible to perform a style study such as the use of a standard tube support device and the use of a common support, and it is possible to significantly reduce costs. (5) The work can be greatly simplified.

As shown in FIG. 6, step S of the conventional method.
In 105a, S105b, S105c, and S108, the two-dimensional paper materials such as the comprehensive piping diagram and the piping detailed diagram created in step S104 were provided to order the hanger plan / detailed design and production. The hanger style plan design based on insufficient materials was left to the manufacturer. In step S106, the hanger detailed drawing was checked to check economic efficiency and interference. If there was any interference, it was returning to the piping route.

On the other hand, in the present embodiment, the piping design department (plant side) provides the three-dimensional CAD full data to the hanger specialized engineering company as shown in steps S21a and S15a of FIG. To order. Economic design with 3D CAD in collaboration with the piping design department (front loading). As shown in step S16, the three-dimensional CAD checks the interference between the pipe and the hanger (concurrent).

Next, steps S15b, 15c and 18
As shown in, the inquiries are made to several manufacturers based on the hanger specifications clarified by the basic design (separate design and manufacturing order). Here, since the basic design has been thoroughly examined, it is possible to check the hanger device diagram in a short time.

As can be seen from FIG. 1 and FIG. 6, in the present embodiment, piping and hanger planning and interference check (steps S21a, S15a, S16) are the most upstream three-dimensional C.
By integrating with AD, the detailed piping design work and the hanger detailed design and production work are completely separated.

While the conventional method of FIG. 6 is the series design, the method of FIG. 1 can be said to be the concurrent design. The method of FIG. 1 has a simpler work flow than the conventional method of FIG. 6, and has the effect that there is no need to rework the piping design, the hanger cost is significantly reduced, and there is no need to remodel on site.

The following effects can be given as the effects of the concurrent engineering in this embodiment.・ Concurrent design significantly reduces design man-hours.・ Early undertaking hanger design (front loading) enables speedy and accurate design.・ Hanger BQ is reduced and cost is significantly reduced.・ A comprehensive check for interference etc. will be performed on the 3D model, eliminating the need for on-site modification. Regarding the reduction of hanger B / Q,
The number of parts can be reduced by simplifying and simplifying shapes (aggregation, integration, sharing).

In the present embodiment, a piping basic plan including the creation of a piping route on three-dimensional CAD and the heat calculation when a schematic support structure is incorporated in the piping route is performed (step S21a), and The basic plan of the support structure corresponding to the piping route is performed on the three-dimensional CAD (step S15a). A comprehensive check is carried out on the three-dimensional CAD for which the support structure is incorporated in the pipe route (step S16), and when it is recognized that there is interference, or in the plant configuration, the pipe and the support that need to be corrected. Both basic plans of the structure are modified (steps S21a and S15a) and repeated until the existence of interference is not recognized. As a result, a basic plan is made for each of the pipe and its supporting structure.

Next, with reference to FIGS. 1 and 2, step S21a, step S15a and step S16 will be described.

FIG. 2 corresponds to the contents of the flowchart of FIG. 2, steps corresponding to those in FIG. 1 are designated by the same reference numerals as those in FIG.

As shown in step S21a, the plant side inputs the piping route plan on the three-dimensional CAD. Here, the plant side performs heat calculation of the piping system to determine the hanger mounting position and type. The hanger type indicates whether the hanger is a slide type, a spring type, or the like.

Step S15a is performed concurrently with step S21a. In step S15a, the hanger maker inputs the hanger style plan into the three-dimensional CAD. In step S15a, the hanger manufacturer makes a hanger plan corresponding to the piping determined in step S21 by the plant side at any time. In step S15a, the hanger maker shares the three-dimensional CAD data used for plant design with the plant side, and implements a hanger plan corresponding to the pipe shape of each plant.

By performing step S15a having the above contents, there are the following merits. -The hanger manufacturer designs the hanger on the plant 3D CAD that the plant is currently designing, so the shape of each hanger is almost determined at this point.・ Since the hanger is designed by the hanger manufacturer, the details of the hanger are almost decided at this point.

In step S16, mutual confirmation of piping and hangers is performed at the plant side and the hanger maker. After the hanger maker inputs the data of the hanger model into the three-dimensional CAD, the hanger maker and the plant side confirm each other. Further, in step S16, in addition to the above interference check, the pipe shape and hanger style are examined from the viewpoint of plant aesthetics.

As a result of step S16, at least one of the pipe and the hanger (pipe support device) is corrected in the following cases (steps S21a and S15a).

As a result of step S16, there are the following examples that require correction of piping. (1) If there is interference between the pipe support device of the pipe currently supported by the planned support device and another pipe other than that, correct the pipe. (2) If the piping route can be modified and it is recognized that the modification will be optimal in terms of cost and plant aesthetics,
Fix the pipe. (3) If the common support can be used by modifying the piping route, the piping is modified so that it is supported by the common support (reference numeral SA3 in FIG. 4).

As a result of step S16, the following are examples of those requiring modification of the tube support device. (1) If the hanger has a complicated shape, modify the hanger. (2) If the hanger shape can be changed to the standard product, the hanger should be modified to the standard product. (3) Common support is used as a hanger for those that can be commonly supported by modifying the piping route.

Referring to FIGS. 3 and 4, step S1
The initial state before the determination in 6 and the corrected state will be described.

FIG. 3 schematically shows the initial state of the piping / hangers before the determination in step S16. As shown in FIG. 3, the arrangement of the pipes and the pipes is insufficient, and they are supported by a complicated supporting device SA5. Further, the supporting device SA1 supporting the pipe and the cable tray CT3 interferes with the pipe, and the supporting device SA2 supporting the cable tray CT1 and CT2.
And the supporting device SA1 interfere with each other.

FIG. 4 schematically shows the condition of the pipes and hangers after being corrected based on the determination result in step S16. As shown in FIG. 4, the styles of the pipes and the support structures H1 and H2 that support the pipes are changed from the complicated support device SA5 of FIG. 3 to a type of hanging from the ceiling. Also, the cable trays CT1 and C
T2, CT3 and the piping are supported by a supporting device SA3 which is a common support.

In step S16, specifically, the following judgment is made. Regarding piping, it is judged "whether there is a flaw in the piping shape (route)" and "whether the piping route should be modified in consideration of common support". Regarding the support structure, "Confirmation of interference with other pipes", "Examination of common support" and "Examination of weight reduction of hanger" are conducted. This "examination of weight reduction of hanger weight"
Then, the hanger style is comprehensively judged in terms of cost, design, etc., and the hanger form is reviewed. As a result of the judgment in these Steps S16, the support structure is modified or the piping (with the hanger) is modified.

In this embodiment, as a result of step S16,
If it is determined that there is interference, the modifications of both basic plans of the pipe and the support structure (steps S21a and S15a) are connected to the three-dimensional CAD depending on the interference shape, the importance of the pipe, the weight of the supporting device, and the like. The correction method is determined on the system and the automatic correction is performed.

Next, an automatic correction method (steps S21a and S15a) of the basic plan of the piping and support structure, which is performed based on the result of step S16, will be described.

First, the case of changing the piping will be described.

Change of pipe shape due to interference with the pipe support device When the pipe support device (hanger) and the pipe interfere with each other,
It is determined whether the piping route can be changed (first determination step). As a result of the first judging step, when the designer judges that the pipe route cannot be changed, the pipe shape is changed and the pipe supporting device is changed. If the designer determines that the piping route can be changed as a result of the first determination step, then the second determination step is performed. In the second determination step, it is determined whether or not the pipe after the current shape change can be supported by the pipe support device with which the current pipe interferes. As a result of the second determination step, if it is determined in the system that the pipe cannot be supported, the pipe shape is changed and the pipe supporting device is changed. As a result of the second determination step, if the system determines that it can be supported,
The pipe shape is automatically corrected.

Change of piping route due to commonization of pipe support device With the use of the common support, the designer judges whether or not the piping route can be changed (third judging step). If, as a result of the third determination step, the designer determines that the pipe cannot be changed, the common support is not used or the common support does not support the pipe. The result of the third judgment step,
If the designer determines that the change is possible, then the fourth determination step is performed. In the fourth judging step, it is judged whether or not the pipe can be supported by the support shape of the current support (common support). As a result of the fourth determination step, when it is determined that the support is impossible, both the piping and the support are changed. As a result of the fourth determination step, when it is determined that the pipe can be supported, the pipe (route) is automatically corrected according to the support shape.

With the adoption of the standard product as the pipe support device, the pipe shape is changed. Based on the result of mutual confirmation of the pipe support device and the pipe,
Change the piping route from the viewpoint of plant aesthetics. The change of the piping route from the viewpoint of plant aesthetics is performed based on the judgment of the piping designer (plant side).

Next, the case of changing the hanger will be described.

When the hanger is changed due to the interference of the hanger, there are the following two cases.

When there is interference with a pipe other than the pipe to be supported by the pipe support device to be designed, it is first judged whether or not the pipe shape can be corrected (11th judgment step). If the result of the eleventh determination step is that correction is not possible, the hanger shape is changed (changed to a style that avoids piping). As a result of the 11th determination step, if it is determined that the correction is possible, then the 12th determination step is performed. In the twelfth determination step, it is determined whether or not it is possible to additionally support the pipe that interferes with the current support device. As a result of the twelfth determination step, when it is determined that the hanger cannot be supported, the pipe shape is corrected and the hanger is not commonly supported. As a result of the twelfth determination step, when it is determined that the pipes can be supported, the pipe supporting device is changed so as to support the interfering pipes, and the pipe route is changed if necessary. In the case of interference with a pipe support device under the control of another manufacturer, separate consideration is required.

There are the following two cases (a) and (b) for changing the style of the hanger when changing the hanger.

(B) Change to common support When the change to common support is made, it means that the standard product cannot be changed and the current support can be changed. First, it is determined whether or not there are two or more pipes within a fixed (separately confirmed) range of the support (thirteenth determination step). If it is determined as a result of the thirteenth determination step that two or more pipes are not present, the current support is used. If it is determined that there are two or more pipes as a result of the thirteenth determination step,
Next, the 14th determination step is performed. In the fourteenth determination step, it is determined whether or not the pipe shape can be changed. If the result of the fourteenth determination step is that it is impossible, the current support is used. 14th
If it is determined that the support is possible as a result of the determination step, the support range is changed so as to provide common support. Further, it is determined whether or not there is an object to be supported other than the pipe within a certain range of the support (No. 21).
Decision step). If it is determined as a result of the 21st determination step that there is not, the current support is used. Second
If it is determined as a result of the 1 determination step, the 22nd determination step is then performed. In the 22nd determination step, it is determined whether or not the shape of the support target other than the pipe can be changed. If the result of the 22nd determination step is that it cannot be changed, the current support is used. As a result of the 22nd determination step, if it is determined that the change is possible, common support is performed. That is, the tube support device is changed according to the shape of the support target to be added. Common support will be provided for those that can be changed in the piping route and are considered to require common support in terms of aesthetics of the plant.

(B) Change to standard product When changing the style of the hanger to a standard product, first, it is judged whether or not the current support can be changed (third part).
1 decision step). If the result of the 31st determination step is that it cannot be changed, the current support is used. If it is determined as a result of the 31st determination step that the change is possible, the costs are compared between the current support style and the standard product (the 32nd determination step). As a result of the judgment in the 32nd judgment step, if it is judged that the cost is lower when the standard product is changed, then the 33rd judgment step is performed. In the 33rd determination step, it is determined whether or not the pipe shape needs to be changed. If it is determined that the change is necessary as a result of the determination in the 32nd determination step, the pipe shape is changed and then the standard product is changed. As a result of the judgment in the 32nd judgment step, if it is judged that the change is unnecessary, the standard product is directly changed.

In the above description, the basic plan of piping and its modification (step S21a) and the basic plan of the supporting structure of piping and its modification (step S15a) are performed on the same (same type) three-dimensional CAD. I explained that I was told. Instead of this, steps S21a and S
The following method can be performed such that 15a and 15a are performed on different three-dimensional CAD. An exclusive website for the three-dimensional CAD is provided, and a user ID and password are given to the hanger maker, and then access (input) to the site is possible. MO and CD-R are used. As described above, the necessary data can be exchanged between different three-dimensional CAD.

As described above, when step S21a and step S15a are performed on different three-dimensional CADs, the three-dimensional CAD in which the basic plan of the supporting structure of the pipes is performed is executed. From the 3D CAD where the basic plan was made, to the building in that plant,
The pipe support data corresponding to the pipe route can be input so that all information such as the equipment is shared with the pipe support device manufacturer.

Further, as described above, when step S21a and step S15a are carried out on different three-dimensional CADs, the three-dimensional CAD on which the basic plan of piping is modified is changed to From the three-dimensional CAD for which the support structure design has been performed, data regarding at least the pipe support model of the basic plan of the pipe can be input.

In the present embodiment, the cost associated with the change of the pipe and the pipe support device can be calculated. The cost calculation calculates the weight (mass) of the piping and the support structure and converts the weight (mass) into the cost. When a standard product is used as the support structure, the cost can be calculated inexpensively.
