DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a system for making structural design information versatilely usable for production planning and a structural database CAD used for the system.

[0002]

2. Description of the Related Art Conventionally, drawing information as a means of transmitting information on building production has generally been in the form of "paper", but in recent years, with the progress of computerization in various areas of building production, CAD is generally used. It is becoming.

[0003] The immediate purpose is to improve the drawing efficiency and the quality of the drawing expression. As can be seen from the purpose, the range of use is mostly limited to the area of each design or construction proper.

However, it is clear that the greatest utility of computerization, including CAD information, lies in the versatility of data. In order to make the most of this characteristic and to improve the efficiency of building production, it is necessary to use a project. It is necessary to distribute design information generated at the initial stage while exchanging data along each stage of production.

At the structural design stage, the structural information includes “structural planning”, “structural calculation”, “structural design drawing creation”, “estimated quantity creation”.
Etc. Fig. 21 explains the flow of information on the skeleton in the current design and construction.
Based on the basic design drawing 2 and the structural planning support system 3 as input information, the key plan-like drawing expresses whether or not there is a member at a certain position and what kind of shape there is. The structural sketch 1 to be created is usually created by handwriting or the like.

At the stage when the structural sketch 1 is completed, the work of structural calculation and the creation of a structural design drawing are performed in parallel and separately, and the drawing is made using a two-dimensional CAD (beam) drawing.
10 and framing diagram creation 11 etc.

[0007] In the structural calculation, as a structural calculation system, cross-sectional information of a rough member of a building and arrangement information of the member, or load information (input) 4 and shape information (input) 5 are input as calculation data, thereby performing stress analysis. 6. Structural calculations such as cross-section calculation (main and auxiliary) 7 etc. can determine the exact cross-section of each member. This is taken into the drawing work side to create a cross-section list 11 and finally the design book The above-mentioned (beam) floor plan creation, frame construction drawing creation 11, section list creation 12 and other details of the reinforced steel frame detailed drawing creation 13 are performed. On the other hand, in the case of calculation work, the holding strength examination 8 (Examination of seismic resistance) is performed, and the whole is consolidated in the form of structural calculation report 9.

[0008] The drafting of the structural design proceeds with the architectural design and the facility design while making it, and corrects it by hand while looking at the paper. The quantity is also checked manually by looking at the completed level drawing. Each work is performed as an individual work, and the drawing drawing 10, the frame drawing drawing 11, and the matching between the planar drawing and the three-dimensional drawing are currently performed using two-dimensional CAD. Is also performed manually.

[0009] The creation of a floor plan 10, the preparation of a frame diagram 11, and the creation of a detailed diagram of a reinforced steel frame 13 are related to each other, but if there is any change, all of them are manually checked out. We are working to fix them separately.

[0010]

As described above, although two-dimensional CAD is conventionally used, data is re-inputted separately, which requires much trouble. Furthermore, even in the interior of the two-dimensional CAD, the drawing is made by separately inputting a plan, a frame diagram, a section list, a detailed view, and the like, so that it is difficult to check consistency.

A structural design drawing 14 as a drawing is plotted out, and accordingly, a CAD graphic file 15 and a DXF file (a standard format for replacing CAD line information with character information) 16 are converted graphic files. Drawings 17 are produced in the form of paper, and these are handed over to the construction stage, where they are manually entered again to produce the construction drawings CA.
D23, steel frame CAD24, reinforcing bar CAD25, equipment CAD26, integration system 27, etc. are input again. This requires a lot of labor, so in the general construction industry (general contractor)
Other than D is rarely used.

Other construction systems are used by cooperating companies such as cost estimation offices, steel frame fabs, and reinforcing steel processing companies, but the burden required for input is large. Although the DXF file 16 is used for data conversion in part, the purpose, accuracy, expression method, etc. are different between the structural design drawing and various construction drawings, and the usable range is limited. It takes a lot of time.

[0013] The structural design drawing is not only a product of the structural design, but also functions as a means for transmitting and organizing information in simultaneous and parallel work. Then, continuous use of data expressing architectural meaning and data linking with other systems could not be considered simply by information of lines as figures.

[0014] CAD linked with the integrated structural calculation system
Drawings were basically the same, especially for floor plans and frame drawings related to the arrangement of members, which were inconsistent with the flow of the design work, and their accuracy was not satisfactory.

[0015] It should be noted that there is no system that can link CAD drawing information to a structural calculation or integration program among commercially available software. For example, a system called Sirius inputs calculation data created by the structural calculation system into its own data file, and also when inputting member cross-sections and layout information, generates a floor plan,
A cross section list is generated, and a detailed diagram of a reinforced steel frame is created.

The information to be input to the CAD drawing is used as it is as the data before the drawing is edited.
D, steel frame CAD, rebar CAD, equipment CAD, and integration system can be used.

However, this system called Sirius does not go through a procedure for creating a drawing, but the drawing is automatically completed through a process called drawing generation as the building building information is input as data. The structure was not satisfactory because the data was not linked bidirectionally.

An object of the present invention is to solve the inconvenience of the prior art, and to unify the structural design information in the structural design department and pursue the efficiency of the design work. The original data of calculation and structural drawing can be generated, and various drawings of structural design and structural calculation can be automatically matched, so that the efficiency of design work can be improved.
The obtained building information can be handed over to the construction department during the design or after the completion of the structural design, and the construction department can easily input this building information into a CAD system for commercial construction, so that construction drawings can be created and processed at the early stage. Structural design information use system and structural database CAD that can assist in production planning and production management work by quickly grasping and tentatively planning the number of skeletons and easily feeding back the results from the construction department to the design department Is to provide.

[0019]

According to the present invention, the structural design department unifies the structural design information by utilizing the skeleton database CAD using a file of a specific format of the present system which is a three-dimensional CAD, and pursues efficiency of the design work. it can.
Also, at the design stage, the planning result is automatically input to the skeleton database, and thereby the original data of the structural calculation and the structural drawing can be generated. Since various drawings of structural design and structural calculation can be automatically matched via the skeleton database, the efficiency of design work can be improved.

Further, the building information automatically generated by the skeleton database CAD can be transferred to the construction department during the design or after the completion of the structural design as character information data (frame data).

In response to this, the construction department inputs the skeleton database to the CAD system for commercial construction, thereby early creation of construction drawings, early grasp of the number of skeletons at the construction stage, provisional design drawing, production planning and production management. Support business. The result can be easily fed back from the construction department to the design department.

[0023]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a flow of an embodiment of a system for using structural design information according to the present invention and a structural database CAD used in the system. FIG. 20 is a block diagram showing an entire system configuration, and FIG.
The same components as those described above are denoted by the same reference numerals.

First, the structure database CAD according to the present invention will be described.
Referring to FIG. 30, a three-dimensional building model as shown in FIG. 2 is mainly used, and on the one hand, it functions as a drawing CAD, and on the other hand, it is integrally linked with a database. Specifically, C
When a drawing is created by AD, drawing information is automatically stored as character data in the skeleton DB via a building model, and conversely, if data in the skeleton DB is changed, the data is automatically reflected in the drawing.

The contents of the input data to the structural database CAD 30 include general information (building outline, material information, etc.), axis information (street name, span, floor height, etc.), member cross-sectional information (cross-sectional shape, reinforcing bar, steel frame, etc.), Member placement information (member placement,
Rotation, shift, etc.), basic data input is performed by text input using a dialog, and input related to body elements is input by text information in a dialog.
Is arranged on the CAD screen as shown in FIG.

The editing functions of the structure database CAD 30 include an automatic envelope function for members, an automatic creation function for creating a framing diagram 11 and a detailed illustration 13 of a reinforced steel frame, and a function for creating a section list 29. In addition to the basic CAD functions such as copy, delete, and zoom, many functions such as a rebar fixing semi-automatic operation diagram are included. However, the data related to the designer's decision, such as whether to arrange the reinforcing bars through the reinforcing bars or to fix them, is to be semi-automatically input in a dialogue format, and the system is capable of responding to diversity.

As an output diagram, a top view as shown in FIG.
There are a framing diagram (automatically created) as shown in FIG. 5 and a rebar detailed diagram (automatically created) as shown in FIG. 6, and also a detailed steel frame diagram (automatically created), a section list (semi-automatically created), a skeleton There is a DB output, and a layout function for creating various mixed drawings is also provided.

Next, such a structure database CAD30 is used.
The structure of the skeleton database 31 as a product of the above will be described. In the present embodiment, in consideration of correspondence such as various conversions,
The table format of MS-ACCESS was adopted.

Of the structural design information, general information on the building, information on the material, and information on the section of the member are input at the time of access.
Stored as a file. On the other hand, information on the shape of the building and the arrangement of the members is held as a three-dimensional CAD model at the time of input operation. The data structure at the time of this input operation is shown in FIG.
Shown in

As described above, at the time of the input operation, the arrangement information is
, Matching by sharing information between the floor plan and the framing diagram can be realized with a practical level of response.

On the other hand, when performing data linkage between the structural database CAD 30 and the external system, information stored as CAD data is accessed by batch processing in ACCESS.
Sweep out to a file. In this way, a skeleton database 31 in which the entire structural design information is unified into a certain format can be formed.
FIG. 8 shows the data structure at the time of conversion.

The flow of the work procedure is to input information in the conventional structural sketch part and to connect it to the design drawing. The menu items displayed on the screen after the system is started are not shown. Are “Building shape definition”, “Standard specification definition”, “Member section definition”, “Floor plan creation”, “Steel construction drawing”
“Creating a section list”, “Structural DB output”, “Reinforcing bar detailed drawing”, “Steel frame detailed drawing”, “Drawing layout”, and the like.

The building shape definition is used to input a building outline as general information. As shown in FIG. 9, by designating a span length and the number of spans in each of the X and Y directions and a street code, orthogonal cross centers are collectively input. As shown in FIG. 10, the floor information setting for inputting the floor data of the number of floors to the building is performed.

In the standard specification definition, as shown in FIG. 11, a design standard strength is set for each floor and each site. The member cross section definition is, for example, an input screen as shown in FIG. 12 for the column cross section definition. A code and a floor are displayed on the member cross section currently being edited.

Next, a plan is created. In this process, members are arranged on a diagram showing the street center defined in the building shape definition. 13 to 15 show examples of the case where pillars are arranged as members. 13 shows a shape, FIG. 14 shows an arrangement, and FIG. 15 shows an attached input screen.

When the beam plan for each floor is completed, the key for creating the frame diagram is pressed, and the frame diagram is automatically generated as selected by instructing to select the drawing. Since the diagram and the framing diagram are automatically aligned, if one of them is corrected, the related matter is also automatically corrected. If there is any change as an integral building, the related drawing can be automatically corrected by inputting it once, so there is no work to list each individually and check it again. It is much easier to respond to design movements.

If the section information in the above-mentioned member section definition is also corrected in the same manner, the beam plan, the framing plan, and the like are also automatically corrected, so that the section information, the planar arrangement information, and the three-dimensional arrangement information are obtained. Are semi-automatically matched. The section list 29 is created by modifying the information of the section that has been drawn once from the information on the input of the member section, and if that section is selected and plotted again, the section is automatically drawn with the new information. The member cross section input can be corrected while correcting the cross section list 29.

Regarding the detailed diagram 13 of the reinforced steel frame, since the detailed diagram of the reinforced steel frame is a considerably complicated drawing, parts that cannot be automatically drawn are input and completed later.

As described above, the structure of the skeleton database 31 is repeated. However, when the cross-section information is input, the operation is to create a cross-section data file in the skeleton database 31 immediately. The section of the member to be arranged is always dropped while referring to the skeleton database 31.

On the other hand, the arrangement information is recognized as attribute data of CAD three-dimensional data, but can be stored in the form of a skeleton database 31 by a simple command. As a result, the input cross-sectional information and the arrangement information of the members in the building input through the beam plan can always be stored as a clearly defined file in the form of one frame database 31. As mentioned earlier, the file is ACCESS
It is a form of information, and various information is confirmed in the form of a table.

Using this frame database 31 as a medium, it is also possible to perform operations for structural calculation and cooperation at the midpoint of design. First, it is possible to drop the structural database created from the sketches instead of the sketches into the layout of the skeleton database 31 and automatically obtain calculation data such as load information (input) 4 and shape information (input) 5 from the information. Can be

When the detailed section including the rebar is determined by performing the section calculation 7, this information is stored in the skeleton database.
By returning to 31, the section information and the like determined through this are semi-automatically reflected on the beam plan and the detailed view of the section list.

The cross section may change at the time of the examination of seismic resistance in conducting the holding strength examination 8, but if information is returned even at that time, the beam plan, the framing chart and the section list in the CAD are similarly obtained. , Can be reflected in the detailed view.

Further, it is possible to cooperate with another system at the structural design stage. Linking with the structural planning support system 1 is the development of a structural planning support system that can instantaneously process hypothetical sections, frame quantity calculations, cross-sectional calculations, etc. from information with less basic planning stage.
It is conceivable to facilitate the creation of the D drawing.

In cooperation with the integrated structure calculation program, by automatically creating initial input data and linking the calculation results directly to the frame database 31 of the present invention system, it is possible to unify drawing information and structure calculation. Become.

In cooperation with the frame quantity integration program,
It is also conceivable to link to a commercially available skeleton integration program at the design roughing stage to check the number of skeletons of main structural members and the settlement stage after design confirmation.

In the construction stage, various construction CADs, such as construction drawings CAD23, steel frame CAD24, reinforcing rod CAD25, equipment CAD26, integration system 27, etc., have been developed and marketed for each specialized construction. However, since these were developed on the assumption that they would be used by subcontractors specialized for specialty work, it is common to manually enter each one separately, which is extremely labor-intensive.

However, in the above-mentioned various commercially available construction CADs, the input of the cross-section information and the arrangement information including the street core, the floor height, and the like is common to all types. In other words, if the content of the original structural design drawing is provided in the form of numerical information, it can be input with a simple conversion program.

Therefore, according to the present invention, a conversion program (IF) for converting each of the commercially available CADs from the skeleton database 31 is prepared, and the commercially available CADs can be easily used. Next, the merits of data CAD for construction CAD for individual tasks will be described.

The cooperation with the steel frame CAD24 facilitates the selection of the lifting machine by knowing the steel member unit weight in the drafting of the tentative design plan. SRC
In the construction, it is possible to easily determine the through-hole of the reinforcing bar, which has conventionally taken a lot of trouble, and it is possible to examine accessories such as exterior fasteners, thereby eliminating the need to rework the drawing. Further, it is possible to reduce the work of the settlement work at the time of design change. Not only the steel weight but also the welding length and the number of bolts can be easily grasped.
FIG. 16 shows an automatic operation diagram based on the steel frame CAD24, and FIG. 17 shows a quantity report.

In cooperation with the reinforcing bar CAD25, it is possible to examine the detailed arrangement of the reinforcing bars on all the frame faces, obtain a high-precision reinforcing bar quantity, output to a workbook, and start construction. The rebar processing company can take into account the construction process and processing time, and can make a factory production plan.The foreman who created the processing book can concentrate on site management, and by grasping the number of work distinctions, Precise and rational process management, such as loading plans, becomes possible. FIG. 18 shows an example of a work book using the reinforcing bar CAD25.

In cooperation with the construction drawing CAD23, the original drawing of the skeleton drawing can be automatically generated, and the drawing work can be sped up and labor can be reduced.
FIG. 19 shows an example of an automatic operation diagram based on the construction drawing CAD23.

In cooperation with the equipment CAD 26, the original drawing of the skeleton can be created quickly, so that it is possible to quickly respond and rationalize the creation of the equipment construction drawing. Since the same skeleton database is used, consistency with the building construction drawing can be maintained. It is possible to secure catalog information and take catalog information based on the same idea as that of the skeleton database.

Further, in the construction drawings, there are various drawings such as a steel frame diagram, a reinforcing bar diagram, a skeleton diagram, and a facility construction diagram.
There are also temporary design drawings and construction procedure drawings. The one that covers all of these drawing information is the ideal overall construction drawing. Although the concept of "construction drawings" is not very common, when using CAD in the construction department, it is very important to ensure consistency and eliminate inconsistencies between factory-made products and the site.

In the case where the skeleton drawing is distributed to the cooperative association forest and the drawing of the construction and construction drawing of each forest is drawn below, and only the information of the part of the company is returned to the main contractor, Collects all construction information and checks it by "overlapping" it on CAD. If there is a discrepancy, request corrections from each company and receive design approval when consistency is established. However, in the current severe social situation, the decision of the supplier is delayed, there is no time to create the drawing by the cooperating company, and sometimes it is not possible to “superimpose”, and with the system of the present invention, the construction drawing can be made quickly and easily. If it can be created, "1 comprehensive map" can be operated efficiently.

[0056]

As described above, the structural design information utilization system of the present invention and the structural database CAD used in the system are unified by the structural design department in the structural design department.
The pursuit of efficiency in design work can be pursued. At the design stage, the planning results are automatically input, so that the original data of structural calculation and structural drawing can be generated, and the various drawings of structural design and structural calculation can be automatically matched. Therefore, the efficiency of the design work can be improved.

Further, the obtained building information can be transferred to the construction department during the design or after the completion of the structural design, and the construction department can easily input this building information to a CAD system for commercial construction, thereby enabling early construction drawing. It is possible to support the production planning / management work at an early stage of grasping and tentative planning of the frame quantity at the preparation / construction stage, and it is also easy to feed back the results from the construction department to the design department.
