Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a design information processing method for a CAD system for buildings, and in particular, can be used for designing unit buildings and the like.

[0002]

BACKGROUND ART In recent years, CAD systems have been used for architectural design of buildings. The CAD system pre-stores various design elements necessary for building a building (for example, parts such as columns, beams, fittings, and bus units), and arranges the parts required by the designer on the display. Then, the building is designed.

[0003]

By the way, when designing a so-called free-plan building in which the floor plan is set in accordance with the customer's request, the parts to be used and the construction method should be CAD according to the detailed structure of the floor plan. It was necessary to use the instructions and design, and the design work was complicated. In particular, in a unit building, the number of parts is larger than in the conventional construction method, and the strength calculation when combining each part is complicated (In a unit building, each building unit reaches the structural strength required for transportation. Structural calculation for each building unit to confirm whether or not the structural strength of the entire unit building has reached the required structural strength when the building units are combined. There is a problem that the design work is complicated and the cost is high especially when a part of a free plan building or a pre-planned building is changed.

For example, when a building unit having a height of a predetermined module (unit size representing the size of a building unit) is changed to a higher floor height unit in accordance with a change in floor plan, the pillars of the building unit are lengthened. Not only is it changed to a longer size, but the strength required for transporting the building unit also changes accordingly, so it is necessary to reinforce the beams and columns with metal fittings that join the columns and beams. I had to make design changes in a wide range. Therefore, conventionally, it is difficult to freely design the unit building according to the order, the floor plan is fixed, the range of variation is narrow, and it is not possible to sufficiently meet the customer's order,
In addition, even if the customer wants, there is a problem that the unit building may not be constructed because there is no plan corresponding to the site.

The object of the present invention is to provide a building CA capable of easily responding to free plans and design changes in a unit building and flexibly responding to customer orders to design a building.
It is to provide a design information processing method of the D system.

[0006]

A design information processing method for a CAD system for buildings according to the present invention is a design information processing method for creating and processing design information including a plurality of design element information. The design element data indicating the information of the design element itself represented by the element information, and the related data consisting of the component data indicating the other design elements constituting this design element and the production / construction data related to the production / construction of the design element The feature is that the design element information is configured.

At this time, it is preferable that the constituent element data and the production / construction data constituting the related data are composed only of index data capable of quoting other design elements and actual production / construction data. Further, the design element information is hierarchically associated with other design element information through the related data, and when predetermined design element information is selected, other design elements hierarchically below it are selected. Information is also preferably selected.

The design element data is data representing the dimensions, materials, shapes, etc. of the design elements (parts) constituting the building, data representing the structural form, layout, etc. of the design elements. For example, when designing a unit building, the design element data includes building units (standard units, floor height units, trapezoidal units, etc.) and panels that make up each building unit (ceiling, floor, wife, girder panels, etc.). , Dimensions of various design elements such as columns, beams and brackets that make up each panel,
Material and shape data, building structure (unit structure, panel structure, etc.), building unit structure (box type, etc.),
It consists of various structural types such as the outer wall structure of the building (curtain wall structure, etc.), the structure of each joint (welding, bolting, pin connection, etc.), or the arrangement of various equipment such as building units and piping.

On the other hand, the constituent data of the related data is composed of a constituent parts list constituting the various design elements, and the production / construction data is a process drawing, a production manual, an order for parts necessary for factory production. It consists of data, unit layout drawings, construction manuals, etc. necessary for construction at the construction site.

[0010]

Such as a display device 4, an input device 5 such as a keyboard, a mouse, a tablet, a touch screen, a light pen for issuing various operation instructions to the design processing device 3, and information, drawings, manuals, etc. obtained by the design processing. And an output device 6 such as a plotter or the like for printing and outputting.

Each of these devices 3, 4, 5, and 6 may be one device or a plurality of devices, and may be installed according to the number of designers. Further, when a plurality of design processing devices 3 are provided, information may be transmitted between the devices 3 by using communication means or the like. At this time, only one design element database 2 may be provided in order to ensure consistency so that each design processing apparatus 3 can refer to it. The design element database 2 is stored in a storage medium such as a hard disk, CD-ROM, magneto-optical disk, or the like.

The design element database 2 is composed of design information 10 composed of a plurality of design element information 11 representing various design elements, as shown in FIG. As the design element, for example, a building unit, a roof panel, or the like, which is manufactured at a factory and is transported to a construction site, is not only a building component that constitutes a unit building, but also a wife panel, a floor panel, a ceiling panel that configure each building unit, Various parts such as pillars, beams, brackets, face materials (PALCs, plate materials) that configure these panels, and facility parts such as wiring and piping are included. In addition, among the building units, there are box-shaped standard units, floor height units with a height larger than the standard units, floor low units with a height smaller than the standard units, trapezoidal units, setback units, etc. There are various units, and the design element information 11 is created for each unit.

The design element information 11 is the design element data 12
And related data 13. The design element data 12 is input with information of each design element itself, for example, various data 14 such as dimensions (module dimension data and the like) of each component, shape, structural form, arrangement, specification, integration and the like.

The related data 13 is composed of component data 15 and production / construction data 16. The component data 15 is input with the component list data 17 representing the components (which also serve as the design elements) constituting the design element. In addition, as the production / construction data 16, various drawing data 18 such as design drawings, manufacturing process diagrams, unit layout diagrams, and construction process diagrams, and manual data 19 for production and construction used in factory production or on-site construction are input. Has been done.

Component list data 1 of related data 13
7, drawing data 18, and manual data 19 consist only of so-called index data, and these actual data are shown in FIG.
As shown in FIG. 4, the display device 4 refers to other design element information, drawing data, and manual data based on the index data.
It is configured to be displayed on or printed by the output device 6. Therefore, as shown in FIG. 4, the design information of the unit building is obtained by designating the first-level design elements 41 from the first-level design elements 41 such as various building units and roof panels which are produced at the factory and combined on site. Second-level design elements 42 such as various types of constituent panels, and third-level design elements 43 such as pillars and beams that configure the second-level design elements 42 are hierarchically arranged, and higher-level design When an element is selected, the lower level design element is automatically selected by the design processing device 3.

Each design element information 11 is a database file divided for each design element, for example, a building unit database, a roof panel database, a wife panel database, a floor panel database, a ceiling panel database, and a manufacturing drawing. It is configured by dividing it into various files such as a database for construction, a database for construction drawings, a database for manuals (at a finer level, for example, for each pillar or beam), and the design information 10
Is preferable in that the maintainability and the like can be improved.

Further, the related data 13 of some of the design elements also includes request information for requesting another design element to change the structure or member, and when the design element having this request information is selectively arranged. In addition, the design processing device 3 is configured to change another design element based on the request information or display a message requesting the designer to change the design element.

In this embodiment, the arrangement of each unit and the unit structure such as stairs, stairwells, windows, doors, etc. arranged in the unit are influenced based on the rough layout according to the customer's request. Set the opening position and set the basic unit layout structure. At this time, if the standard unit registered in the design element database 2 can be used, select from the list of standard units displayed on the display device, and specify the placement position of the selected unit on the design placement screen. Then, the unit structure is displayed on the screen and the unit building is designed.

On the other hand, when there is no corresponding unit in the list, the wife panel, ceiling panel,
It is designed by selecting each floor panel to form a desired unit and using it, or by replacing a part of the units in the list, for example, only the wife panel with another wife panel. Further, when there is no corresponding panel, a desired panel may be designed and combined by appropriately combining pillars, beams, face materials and the like. The design element newly constructed in this way is
By registering and saving in the design information 10 according to the frequency of use,
It can be used again.

Further, in the case of changing the design of a part of a unit building that has been designed once, in the case of changing it in units, a unit may be newly selected and arranged in that part. When changing, the panel, pillar, beam or the like of that portion may be newly selected and arranged.

Each design element information 11 includes related data 13
Since each design element is selected and arranged on the screen, the design processing device 3 refers to the related data 13 of the design element information 11 to create a manufacturing drawing, a construction drawing, and various manuals. It is extracted from the database, edited as appropriate, and printed by the output device 6. Further, the design processing device 3 edits the parts list necessary for each design element, creates an order sheet and performs ordering processing, and performs integration processing.

Further, the design processing device 3 uses the related data 13
If there is request information in, the design process is performed based on that information. For example, if the gable panel is changed from one without openings to one with openings such as windows and doors, the strength of the panel part will decrease, so reinforcement materials must be added to the ceiling panel and floor panel. There is. For this reason, request information requesting that a reinforcing material be added to the ceiling panel or floor panel is added as related data 13 to the wife panel having an opening of a predetermined size or more, and the design processing device 3 issues the request information. Then, the reinforcing material is automatically added to the target ceiling panel or floor panel, or the designer is requested to add the reinforcing material to the ceiling panel or floor panel.

By repeating the above-mentioned work of arranging the design elements and performing necessary processing, a unit building according to the customer's request is designed.

According to this embodiment, the design element information 11 representing each design element is composed of the design element data 12 which is the information of the design element itself, the component element data 15 and the production / construction data 16. Since the related data 13 to be stored is packaged and configured, it is possible to easily select and change design elements in the building design work.
That is, when designing or changing the design by a free plan, it is necessary to set parts and structures according to individual detailed structures, etc., but according to this embodiment, predetermined design elements can be set according to an order. It is only necessary to arrange or change, and individual detailed structures (parts such as columns, beams, brackets, joint structures, etc.) are defined as the related data 13 of each design element, and the designer does not have to design them individually. Even if the design element is changed, it is automatically changed and set, so that the design work can be greatly saved. Therefore, it is possible to save the labor of designing and changing the unit building, so that the customer's order can be freely and promptly dealt with.

Further, since the related data 13 also includes request information affecting other design elements, it is necessary to dispose a reinforcing material for strength reinforcement due to a change in some design elements. However, the design change can be surely performed by the design processing device 3 automatically displaying the design change or by displaying a message prompting the designer to carry out the change, thereby preventing a design mistake such as redesigning due to insufficient strength. be able to.

Further, since the related data 13 also includes the related parts list data 17, it is possible to automatically perform the integration process and the ordering process of the parts accompanying the design change and the free plan design. Also, various drawing data 18 such as production drawings, construction drawings, and process drawings, and production / construction data 16 such as manual data 19 for production and construction are related data 13
Since it is included in the above, it is possible to create various drawings and manuals according to the designed unit building by appropriately editing the data 18 and 19. For this reason,
It is not necessary to create a large number of drawings or manuals in consideration of various variations in advance, and the designer or operator needs to find and refer to the necessary drawings or manuals from these large numbers of manuals or drawings. Therefore, workability during production and construction can be significantly improved.

Further, in the above embodiment, the design elements are configured as hierarchical data such as units, roof panels, etc., each panel constituting the unit from the first level, and further columns, beams constituting each panel. Therefore, it is possible to flexibly change according to each hierarchical level, and it is possible to perform flexible design processing. That is, when changing the design,
You may change each unit at the building unit level, or you may change only the lower level wife panel,
Since the modification process can be performed in various hierarchies, the design modification can be performed at the level where the modified part is minimized. In addition, because it is hierarchical, if you select and change a predetermined design element,
Each design element information expanded to the lower level is also automatically selected and changed, and the workability at the time of design can be further improved.

Further, in the above embodiment, only the index data 17, 18 and 19 for identifying the related data 13 are stored in the related data 13 of each design element, and the actual data of each related data 13 is The index data 17, 18,
Since it is configured to be obtained by referring to 19 as a reference, for example, when the same panel is used as the related data 13 in different units, the related data 13 of each unit is
Since it is not necessary to store the actual data of the panel in one place, the actual data of the panel need only be stored in one place, so the storage capacity can be reduced, and maintenance such as data change only needs to be done in one place, which is easy. Can be done.

The present invention is not limited to the above-mentioned embodiments, and modifications and the like within the range in which the object of the present invention can be achieved are included in the present invention. That is, the design information processing method of the present invention is not limited to the case of designing a unit building as in the above embodiment, but can be used for designing various buildings such as a panel construction method and a conventional construction method.

Further, the related data 13 of the design element information 11
Is not limited to one that is composed of only index data as in the above embodiment, but actual data may be stored in each related data 13. However, it is advantageous that the index data is used as in the above-described embodiment because the data capacity can be reduced and the maintainability can be improved.

Further, the data structure of the design information 10 is not limited to the hierarchical data structure, and various conventionally used data structures such as network data and relational data can be adopted. Further, the data types stored in the design element data 12 and the related data 13 are not limited to those in the above-mentioned embodiment, and may be set appropriately according to the type of building to be designed.
