Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a CAD system for a unit building and is used for designing a prefabricated building constructed by assembling a plurality of box-shaped building units.

[0002]

BACKGROUND ART Prefabricated buildings have become rapidly popular in recent years because of advantages such as cost reduction and quality stabilization due to industrialization. Of the prefabricated buildings, the axial curtain wall method is similar to the conventional method, and is constructed by assembling pillar beams and wall surface materials produced at the factory.
In addition, the wooden panel construction method is constructed by assembling the panels produced at the factory on site. The building of each of these prefabricated construction methods is configured as an assembly of simple members such as shaft members and face members. On the other hand, in the prefabricated building, the unit method is to produce a box-shaped building unit in a factory and assemble it on site, and production, transportation, and site construction are basically unit units.

[0003] These prefabricated buildings were generally provided as planned buildings. The planned construction is a building maker designing from the outline of the floor plan and appearance of the building to the details such as the type of built-in equipment and the specifications of the interior and exterior. However, even in planned construction, there are many cases in which several options can be selected regarding the floor plan, equipment, and specifications according to the customer's request.

However, in recent years, the demands of the owner have diversified, and it has become impossible to obtain sufficient customer satisfaction with a uniform plan building or option selection, and even in prefabricated buildings, orders for various individual designs are made. Correspondence to architecture is demanded. Here, in dealing with custom construction,
It is necessary to redesign each building from the beginning, and the design work of the building maker becomes enormous compared to the conventional planned housing.
For this reason, in order to handle orders for prefabricated buildings, it is necessary to introduce a CAD (Computer Aided Design) system in order to improve work efficiency.

[0005]

By the way, among the above-mentioned prefabricated buildings, the unit building has a problem that it is difficult to deal with custom-built construction and to make CAD, as compared with other prefabricated construction methods. In other words, in the case of custom-built construction in a framed building or panel type building, the outline of the floor plan etc. is summarized according to the owner's order, and the detailed structure and the specific parts that embody it are summarized and the design drawing is created. After the owner's confirmation, the design is completed, leading to parts production and construction. In other words, in this type of building, the entire building is simply regarded as an assembly of parts, and therefore, the outline of the floor plan and the like, and the detailed design of the members and structures used are inseparable and continuous. Therefore, CAD can be performed relatively easily by following a series of design contents, and there is no particular difficulty in ordering, because the design work is simply redone.

However, in the unit building, since the handling is carried out on a unit-by-unit basis as described above, the design requires an intermediate design level for the unit as a unit between the simple member level and the level of the entire building. Is. Especially, it is necessary to secure the structural strength of the frame of each unit in the state of being built in the building, and also to secure the self-supporting strength of the unit as a single unit in consideration of handling during transportation. The work becomes complicated.

From the above, in order to make a drastic change in the schematic design in a unit building, in addition to redesigning at the level of the entire building, it is necessary to redesign each unit in accordance with the content, and the work and cost are reduced. Will be huge. Further, since a huge amount of processing is required, the speed of the computer apparatus that executes the processing is reduced in CAD, or the cost is increased due to the increase in the speed of the processing apparatus.
There is a problem that it becomes difficult to make it. Also, due to the delay in CAD, the response to custom-built unit buildings was also delayed. An object of the present invention is to provide a unit building design method and a unit building CAD system that can flexibly and swiftly respond to a large design change.

[0008]

The present invention divides the entire CAD system into a basic design and a production design, and in the basic design, an outline up to the basic unit layout of the building (shape and specifications of the portion visible to the owner, Design the functions etc. requested by the owner,
The necessary minimum items that represent the building according to the order are summarized to reduce the workload of the part where design changes are repeated by meeting with the owner, and the details corresponding to the contents decided in the basic design in the production design (the owner is not visible) By designing the structure of parts and the composition of parts), it is possible to efficiently process even complex production designs at the unit unit level.
In the production design, the production design is performed for each of the body, roof, and other parts, and production drawings can be created, accumulated, and ordered. By these, the above-mentioned object is achieved.

Specifically, the present invention is a CAD system for a unit building for designing a unit building constructed by assembling a plurality of building units, the specification of the building including the unit arrangement in the building. And a production preparation system for producing production design information including concrete specifications for each building unit based on the basic design information, and the production preparation system is A production design department that designs a detailed structure and a component structure of each building unit based on the basic design information and creates a production drawing of each building unit or its constituent parts for each division of the skeleton, roof, and other parts. , Create a cumulative list of each building unit and each part based on the production drawing, and based on the cumulative list and the production drawing. Wherein the stomach is composed of a ordering integrating unit for managing the production and ordering of each building unit and each component.

[0010] The production design section includes a skeleton production design section for producing a production drawing of a skeleton portion of the building, a roof production design section for producing a production drawing of a roof portion of the building, and other parts of the building. It is desirable to include a parts production design section for creating production drawings. The production design section is supposed to create integrated data including integrated information of parts used in the drawing together with a production drawing, and the ordering and integration section is integrated based on the integrated data created by the production design section. It is preferable to include a counting section for creating a list and an ordering / ordering section for ordering materials and parts based on this counting list.

Further, it has a design element database created by the production preparation system and referred to by the basic design system, and the design element database has design rules to be observed when designing a building and selectable structures and shapes. It is desirable to include the element list of.
It is desirable that the production preparation system outputs the production design information of each building unit or each part and a production manual and / or a construction manual of each building unit or each part. The production drawing relates to a part diagram showing detailed information necessary for producing individual parts to be used, an assembly diagram showing an assembly state and relation of each part shown in the part diagram, and production and assembly of the part. It is desirable to include a process chart including a manual.

[0012]

According to the present invention as described above, the basic design up to the basic unit layout of the building (shape and specifications of the portion visible to the owner, functions requested by the owner, etc.) is designed and a meeting with the owner is held. Go and summarize the minimum necessary items that represent the building that you ordered. Next, in the production design, details (structure and parts composition of the invisible part of the owner) corresponding to the contents decided in the basic design are designed, and drawings and information necessary for factory production are summarized.

Therefore, the portion where the design change is repeated by the owner meeting becomes simple and easy, the work load of the repeated portion is reduced, and the complicated production design such as the unit unit level is performed once after the basic design is completed. It is only necessary to do it, and it becomes possible to deal with custom houses that require individual design. In addition, since the basic design is mainly an outline design, even if there are repeated work, the production design with a light load and a heavy load can avoid repetition. It is possible to configure the system.

Further, by constructing the production preparation system with the production designing section and the ordering and order integrating section, it becomes possible to efficiently perform the detailed design for the production or the ordering operation.
The production design can be made more efficient by processing it for each section, such as the frame, roof, and other parts. By these, the above-mentioned object is achieved.

Particularly, in the production design department, each section of the frame production design, the roof production design, and the component production design can be made independent, so that the respective sections can be processed in parallel and the efficiency can be further improved. Further, by creating the data for integration when creating each production drawing and using it for the integration in the integration section, the integration process can be efficiently and accurately performed.

Further, the basic design and the production design refer to the common design element database, and perform the respective designs based on the common design standard, so that the basic design is set but the production design cannot cope. It is possible to avoid the inconvenience and reduce the amount of information and the processing load due to coding and packaging of parts and structures. Further, in the production preparation system, it is possible to make the construction work more efficient or ensure the manual supply by creating the production manual for the relevant parts and the like together with the production drawing and the cost list.

It is possible to design the shape and specifications of the part that can be seen in FIG. 12, the function requested by the owner, etc.) and make a meeting with the owner to put together the minimum necessary items that represent the building according to the order as the basic design information W22. In addition, the production preparation system S
By using 30, it is possible to design the details (the structure and the part configuration of the invisible part of the owner) corresponding to the contents decided in the basic design, and put them together in the information such as the production drawing F30 and the integration list L31 necessary for factory production.

Therefore, the part where the design change is repeated by the owner meeting becomes simple, the work load of the repeated part is reduced, and the complicated production design such as the unit single unit level is performed once after the basic design is completed. It is sufficient to do it only, and it is possible to deal with custom houses that need individual design. In addition, since the basic design is mainly an outline design, even if there are repeated work, the production design with a light load and a heavy load can avoid repetition. The system can be configured.

(Effects of Design Element Databases S24 and S33) In the basic design system S20 to the production preparation system S30, reference is made to the design element databases S24 and S33 in which common design element information is registered, and based on common design criteria. By designing each
It is possible to avoid inconveniences such as being set in the basic design but not being able to cope with the production design, and it is possible to reduce the amount of information and the processing load by coding and packaging parts and structures. Further, since the design element databases S24 and S33 are registered on the side of the production preparation system S30 and transferred to the basic design system S20, it is possible to include rules or the like for avoiding difficult parts in production in advance in the registered contents. Even if the basic design and the production design are divided, the design or production can be surely performed.

Further, the design element databases S24, S
In the case of 33 "registered as a rule" but "specific parts are not defined", the production design subsystem S31 enables sequential registration, so that parts that are not likely to be used in advance are parts. Registration can be omitted, and the design element databases S24 and S33 can be made compact by adding them in accordance with the necessity and the frequency of use. As a result, the equipment such as the storage device can be simplified and the cost can be reduced, and the maintainability of the registered contents can be improved.

(Overall Effects of Basic Design System S20) In the basic design system S20, the basic design including the drawing information and the integrated information is constituted by the design design subsystem S21, the integration subsystem S22, and the business subsystem S23. Businesses such as progress management can be efficiently performed while creating the information W22.

Elevation F25 and perspective F required for a meeting with 12
26 can be automatically created.

In particular, in the design design subsystem S21,
Because the design information of the floor plan F21 is automatically referenced during the basic settings of the basic floor plan F22, roof plan F23, and wiring diagram F24 (unit layout, external shape, floor plan, layout of facilities, etc.) , It is possible to save redundant operations for similar settings, and to easily ensure consistency and consistency of design information. Then, the accumulation subsystem S22
Then, the integration list L21 can be automatically created by referring to the design information of the plan view F21 or the wiring diagram F24, and in the business subsystem S23, the quotation L for the owner S12 is created.

(Effect of Floor Plan Section S211 of Basic Design System S20) In the floor plan section S211 of the basic design system S20, the unit setting, the entrance setting, and the balcony periphery setting are sequentially processed to perform the settings relating to the frame and the grid setting. The interior / exterior settings can be made by sequentially processing the outer wall setting and the fitting setting.

Particularly, in the frame subsection S211A, by executing the entrance setting module S2112 after the basic unit setting module S2111, the setting of the entrance portion that requires special processing such as a dirt floor and a rising frame is regarded as the unit setting. Can be processed separately. For this reason,
Even for the part that should be the entrance, the settings related to the unit of the part can be processed by the unit setting module S2111 in the preceding stage like other parts, or the unit setting in the preceding stage for setting the unit dedicated to the entrance, etc. It is possible to avoid inconvenience such as the module S2111 becoming complicated.

Further, in the interior / exterior subsection S211B, the grid indicating the reference position can be set on the previously set unit arrangement by the grid setting module S2114. Since the interior and exterior are set based on this grid, accurate position setting based on the grid can be performed without specifying detailed position dimensions and the like. Further, in addition to the fitting setting module S2116 for setting fittings, the outer wall setting module S
By providing 2115, it is possible to reliably and easily set the outer wall panel, which greatly differs in processing from other interiors and exteriors.

(Effect of Basic Floor Plan Section S212 of Basic Design System S20) In the basic floor plan section S212 of the basic design system S20, the area is determined by the basic setting of the foundation and the entrance setting, and the normal and special crowns are set. In addition, by designing an independent foundation and auxiliary settings, the foundation can be designed.

In particular, after the overall cloth foundation is set in the basic setting module S2121, the entrance setting module S2
By executing 2122, it is possible to process the setting of the entrance portion that requires special processing such as the dirt floor and the raised frame separately from the basic setting. In addition, the basic setting module S2121
After the overall cloth foundation is set by, the independent foundation setting module S2125 can be executed to appropriately set the independent foundation that is different from the cloth foundation and is installed. Therefore, the basic setting module S2121 can perform comprehensive and continuous basic settings without considering entrances and independent foundations, and automation can be facilitated easily by simplifying the processing.

Furthermore, after the basic crown height is set in the crown setting module S2123, the crown height of a special portion is set in the special crown setting module S2124. The processing of S2123 can be simplified, and the special crown can be surely set.

(Effect of Roof Floor Plan Section S213 of Basic Design System S20) In the roof floor plan section S213 of the basic design system S20, the roof shape setting module S2131 sets the basic shape of the roof, and the subsequent gutter setting module S2132 sets the eaves. You can set the gutter and downspout.

Especially, the roof shape setting module S2131
Then, by preparing the standard program S2133 and the replacement program S2134 and substituting a part of the standard program with the replacement program according to the roof shape, various roof shapes other than the standard can be dealt with, and each roof shape can be individually processed. The program size can be made smaller than the case where a complete execution program is prepared, and the maintainability can be improved by sharing the common part.

(Overall Effects of Production Preparation System S30) In the production preparation system S30, the production design subsystem S31 and the order placement / subtraction integration subsystem S32 are provided so that detailed design or production order for production can be performed. Work can be done efficiently. In particular, by designing the contents set in the basic design information W22 in detail by the production design subsystem S31, the production drawing F30 (parts drawing F30) necessary for production at the factory S17 or ordering to the material supplier S16.
31, assembly drawing F32, process drawing F33) can be automatically created. At this time, in the production design subsystem S31, by constructing the skeleton production design section S311, the roof production design section S312, and the component production design section S313, the skeleton and the roof having significantly different processing contents can be separately processed, and The parts etc. used in each can be further processed separately. Then, the order receipt / order integration subsystem S32 can automatically create the integration list L31 with reference to the production drawing F30, and can also automatically create the order sheet L32 for the material supplier S16 and the factory S17.

(Effect of Manual Attachment of Production Preparation System S30) In the production preparation system S30, the parts drawing F31 and the assembly drawing F in the production design subsystem S31.
By creating a production manual (process chart F33) for the relevant parts together with 32, the construction work at the factory or on-site can be easily and surely performed. In particular,
In the production design subsystem S31, since the manual corresponding to the parts used in the building is selected and distributed to the factory or the site, errors such as distribution of manuals not corresponding to the parts used and all parts are handled. Redundancy such as using a manual can be eliminated, and the necessary manual can be surely supplied, whereby the work can be performed easily and efficiently.

(Effect of the frame production design section S311 of the production preparation system S30) In the frame production design section S311 of the production preparation system S30, the outer wall panel expansion, the standard unit expansion, the special unit expansion, and the entrance unit expansion are sequentially processed. It is possible to design the details of the unit part, and to perform detailed design up to the parts to be mounted or attached and shipped to the unit by deploying the frame outfitting parts and deploying the frame shipping parts.

In particular, the standard unit expansion module S3112 for processing general standard units and the special unit expansion module S3 for processing other special units.
By dividing the number of the standard units 113 from each other, it is possible to improve the overall processing efficiency by performing a process optimized for the standard unit having a large number. On the other hand, the special unit expansion module S3113 can surely deal with a large number of parameter settings required for the special unit.

Further, each unit expansion module S311
By installing the entrance unit expansion module S3114 separately from 2 and S3113, the setting of the entrance part that requires special processing such as dirt floor and rising frame can be processed separately from the standard and special unit settings. Whether the formed unit is a standard unit or a special unit can be surely dealt with. Further, prior to the processing of each of the unit expansion modules S3112 to S3114, the outer wall panel expansion module S3111 expands the outer wall panel that is appropriately attached to each unit, so that a specific outer wall support structure is included in the expansion of each unit. Detailed design can be done.

Then, the frame production design section S311
Then, after the above-described unit expansion, the parts to be outfitted in the factory S17 are expanded by the frame outfitting parts expansion module S3115, and the frame shipping member expansion module S
The 3116 allows the members to be shipped together with the unit to be deployed without outfitting. By separating these outfitting parts and shipping members, the skeleton outfitting component expansion module S3115 can process units, and the skeleton shipping parts deployment module S3116 can process members between units in building units. Therefore, reliable processing can be performed.

In the skeleton production design section S311, the integration data L31 is created by the integration data creation module S3117 on the basis of the production drawing F30 developed by the above-mentioned modules S3111 to S3116. The processing in the order accumulation subsystem S312 can be facilitated. Further, the part data registration module S3118 can perform additional registration in the design element database S33 described above, if necessary, based on the production design information W31 including the production drawing F30 and the integration data L31.

(Effect of the roof production design section S312 of the production preparation system S30) In the roof production design section S312 of the production preparation system S30, after the basic shape of the roof is designed, the detailed parts constituting the roof shape are developed. This enables detailed design of the roof. Among them, in designing the basic shape of the roof, the roof shape drawing module S3122 is created based on the basic design information W22 input in the roof information input module S3121.
The basic shape of the roof can be obtained by drawing with.

Further, the roof panel split execution module S3
With 123, it is possible to appropriately allocate the roof panels that form the basic shape of the roof based on the rules registered in the design element database S33. Therefore, even if the roof has various shapes, the allocated roof panels can be easily manufactured and transported.

The processing for inputting roof information or executing the roof panel division can be automatically executed as a series of processing because it is not necessary to input new design information. The special shape information input module S3124 can surely perform special processing that cannot be automated or setting of special parts.

On the other hand, in developing the detailed parts, the roof panel expanding module S3125, the joint hardware expanding module S3126, the vertical parts expanding module S3127,
Since the hut panel expansion module S3128 and the auxiliary component expansion module S3129 share the work, they can be processed sequentially or in parallel.

The same applies to 24 and S33.

In terms of designing the unit building, it is sufficient that the drawings and parts list necessary for the design can be output, and the function of creating the quotation L23, the purchase order L32, etc. may be omitted as appropriate. Further, in the above-mentioned embodiment, the foundation plan F23 created by the basic design system S20 was sent to the site in order to construct the foundation on site. F23 may also be sent to the production design system S30 to perform detailed design of the prefabricated basic component.

As described above, according to the present invention,
Regarding the shape and specifications of the part visible to the owner, the functions required by the owner, etc., it is necessary to summarize the basic unit layout of the building, make a basic design, and hold a meeting with the owner to represent the building according to the order. In addition to summarizing the minimum items, it is possible to compile the details corresponding to the contents decided in the basic design, that is, the production design related to the structure and parts configuration of the invisible part of the owner, and compile the drawings and information necessary for factory production. . Therefore, the part where the design change is repeated by the owner meeting is simplified and the work load of the repeated part is reduced, and the complicated production design such as the unit unit level can be done only once after the basic design is completed. It can be improved and it can be applied to custom-made houses that require individual design.

Further, since the basic design is mainly an outline design, even if there are repeated operations, the production design with a light load and a heavy load can avoid repetition, and therefore each can be individually CAD-made for practical use. A typical CAD system can be constructed. Furthermore, by constructing the production preparation system with the production design department and the ordering and integrating unit, it becomes possible to efficiently carry out operations such as detailed design or production ordering for production. It is possible to improve efficiency by processing for each of the parts.

In particular, in the production design department, by making each section of the frame production design, the roof production design, and the component production design independent, it becomes possible to perform parallel processing, and further improve the efficiency. Further, by creating the data for integration when creating each production drawing and using it for the integration in the integration section, the integration process can be efficiently and accurately performed.

Further, the basic design and the production design refer to the common design element database, and perform the respective designs based on the common design standard, so that the basic design is set but the production design cannot cope. It is possible to avoid the inconvenience and reduce the amount of information and the processing load due to coding and packaging of parts and structures. Further, in the production preparation system, it is possible to make the construction work more efficient or ensure the manual supply by creating the production manual for the relevant parts and the like together with the production drawing and the cost list.
