Description

[0001]
[Industrial application fields]
The present invention relates to a unit building CAD system and is used for designing a prefabricated building constructed by assembling a plurality of box-shaped building units.
[0002]
[Background]
Prefabricated buildings have been rapidly spreading in recent years due to advantages such as cost reduction and quality stabilization due to industrialization.
Among prefabricated buildings, the frame curtain wall method is close to the conventional method, and is built by assembling factory-produced column beams and wall face materials. In addition, the wooden panel method is constructed by assembling panels produced at the factory on site.
Each of these prefabricated buildings is configured as a collection of simple members such as shaft members and face members.
On the other hand, among prefabricated buildings, the unit construction method is to produce box-shaped building units at the factory and assemble them at the site. Production, transportation, and construction at the site are basically unit units.
[0003]
These prefabricated buildings were generally offered as planned buildings. Planned architecture is designed by the building maker from the outline of the building layout and exterior shape to details such as the types of built-in equipment and interior and exterior specifications.
However, even in the case of planned construction, there are many cases where several options can be selected regarding the floor plan, equipment, and specifications in accordance with the customer's request.
[0004]
However, in recent years, client demands have diversified, and it has become impossible to obtain sufficient customer satisfaction with uniform planning buildings or option selection. Response is required.
Here, in order to deal with the custom-built construction, it is necessary to redesign each building from the beginning, and the design work of the building maker becomes enormous as compared with the conventional planned house.
For this reason, when ordering prefabricated buildings, it is necessary to introduce a CAD (Computer Aided Design) system in order to improve work efficiency.
[0005]
[Problems to be solved by the invention]
By the way, among the prefabricated buildings described above, the unit building has a problem that it is difficult to deal with custom construction and to make CAD compared to other prefabricated methods.
In other words, when building a custom-built building with a framed building or a panel building, outline the floor plan etc. according to the owner's order, and create a design drawing with the detailed structure and specification parts that embody it. After the confirmation of the owner, the design is completed, leading to parts production or building construction.
That is, in this type of building, since the entire building is simply regarded as an assembly of parts, the outline from the floor plan planning to the detailed design of the members and structures used are inseparable and continuous.
For this reason, CAD can be performed relatively easily by following a series of design contents, and there is no particular difficulty in redoing the design work for ordering.
[0006]
However, since unit buildings are handled in units as described above, an intermediate design level for a single unit is required between the simple member level and the entire building level for the design.
In particular, it is necessary to secure the structural strength of each unit frame when assembled in a building, as well as to ensure the self-supporting strength of the unit alone in consideration of handling such as transportation. The work becomes complicated.
[0007]
For this reason, in order to make a substantial change in the general design of a unit building, it is necessary to redesign each unit according to the contents in addition to the redesign at the entire building level, which requires enormous work and costs. Become.
Furthermore, since enormous processing is required, the speed of the computer device that executes the processing is reduced in CAD processing, or the cost increases due to the speeding up of the processing device, which makes it difficult to perform CAD processing. There is.
And with the delay of CAD, the response to the custom building of 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 quickly cope with a large design change.
[0008]
[Means for Solving the Problems]
The present invention divides the entire CAD system into basic design and production design, and in the basic design, outlines the basic unit layout of the building (shape and specifications of the parts visible to the client, functions requested by the client, etc.) In addition, the minimum necessary items representing the building according to the order are summarized, the work load of the part where the design change is repeated by the owner meeting is reduced, and the details corresponding to the contents determined in the basic design in the production design (the owner's details) By designing the invisible part structure and component structure), it is possible to efficiently handle complex production design at the unit level. In the production design, the production design is performed for each category of the frame, the roof, and other parts so that production drawings can be created, integrated, and ordered. These achieve the above object.
[0009]
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, Shape and unit layout in the building A basic design system for creating basic design information for designating, and based on the basic design information Structure and component configuration for each building and each building unit And production preparation system to create production design information including The basic design system is set to the standard by replacing a part of this standard program with a standard program for displaying a screen or accepting an input operation for a setting module necessary for setting a roof type set as a standard. A replacement program for generating an operation program for setting a roof type different from the roof type, and a program editing unit for generating an execution program from the standard program and the replacement program based on the designation of the roof type inputted externally, A program execution unit configured to execute the execution program and set the design information of the designated type of roof, and a roof shape setting module configured by: The production preparation system designs the detailed structure and component configuration of each building unit based on the basic design information, and creates a production drawing of each building unit or its component for each category of frame, roof, and other components. A production design department that creates an integrated list of each building unit and each part based on the production drawing, and manages production and ordering of each building unit and each part based on the integrated list and the production drawing. It is characterized by comprising an order integrating unit.
[0010]
The production design section includes a production production design section for producing a production drawing of a building body part of the building, a roof production design section for producing a production drawing of a roof part of the building, and production drawings of other parts of the building. It is desirable to include a part production design section to be created.
The production design unit is to create integration data including integration information of parts used in the drawing together with the production drawing, and the ordering and integration unit is integrated based on the integration data created by the production design unit. It is desirable to include a totaling section for creating a list and a receiving / ordering section for ordering materials and parts based on this totaling list.
[0011]
Furthermore, it has a design element database created by the production preparation system and referred to by the basic design system, and this design element database is a list of elements such as design rules and selectable structures and shapes to be observed in building design. It is desirable to include.
It is desirable that the production preparation system outputs a production manual and / or a construction manual for each building unit or part together with production design information for each building unit or part.
The production drawing relates to a part diagram showing detailed information necessary for production of individual parts to be used, an assembly drawing showing an assembly state and relation of each part shown in the part drawing, and production and assembly of the parts. It is desirable to include a process diagram including a manual.
[0012]
[Action]
In the present invention, an outline (basic shape and specifications of the part that can be seen by the client, the functions required by the client, etc.) is designed, arranged in consultation with the client, and ordered in the basic design. Summarize the minimum necessary items that represent buildings according to Next, in production design, details corresponding to the contents determined in the basic design (structure and parts configuration of the part that the client cannot see) are designed, and drawings and information necessary for factory production are compiled.
[0013]
Therefore, the part where the design change is repeated by the client meeting can be simplified, the work load of the repeated part can be reduced, and complicated production design such as the unit level can be performed only once after the basic design is compiled. It will be better and will be able to accommodate custom homes that require individual design.
In addition, the basic design is mainly an outline design, so even if there is a repetitive work, the load is light and the heavy load design can be avoided. A system can be configured.
[0014]
Furthermore, by configuring the production preparation system with the production design department and the order placement and integration part, it will be possible to efficiently carry out operations such as detailed design for production or cumulative ordering. The efficiency is improved by processing for each category of parts. The above-mentioned purpose is achieved by these.
[0015]
In particular, in the production design department, the sections of the housing production design, the roof production design, and the part production design are made independent, so that each of them can be processed in parallel, and further efficiency is achieved.
In addition, the integration process can be efficiently and accurately performed by creating integration data when creating each production drawing and using it for integration in the integration section.
[0016]
In addition, the basic design and production design each refer to the common design element database and perform each design based on the common design criteria. In addition to avoidance, it is possible to reduce the amount of information and processing load by coding and packaging parts and structures.
Furthermore, in the production preparation system, it is possible to improve the efficiency of construction work or ensure the supply of manuals by creating a production manual for the relevant parts together with production drawings and integration lists.

[0087]
Hereinafter, the effect of the present embodiment will be described.
(Effect of overall structure)
In the unit building CAD system S10 of the present embodiment, basic design related to the outline of the building can be first performed by the basic design system S20, and detailed production design necessary for production can be performed by the subsequent production preparation system S30.
In other words, the basic design system S20 is used to design the outline of the basic unit layout of the building (the shape and specifications of the parts visible to the client S12, the functions requested by the client, etc.), meet with the client, and accept the order. Necessary minimum items representing a building can be collected as basic design information W22.
In addition, details corresponding to the contents determined in the basic design (structure and parts configuration invisible to the owner) are designed by the production preparation system S30, and the information such as the production drawing F30 and the integration list L31 necessary for factory production is designed. Can be summarized.
[0088]
Therefore, the part where the design change is repeated by the client meeting can be simplified, the work load of the repeated part can be reduced, and complicated production design such as the unit level can be performed only once after the basic design is compiled. It becomes better and can handle custom homes that need to be individually designed.
In addition, the basic design is mainly an outline design, so even if there is a repetitive work, the load is light and the heavy load design can be avoided. The system can be configured.
[0089]
(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 each design is performed based on a common design standard, thereby setting the basic design. However, it is possible to avoid inconveniences such as inability to cope with production design, and to reduce the amount of information and processing load by coding and packaging parts and structures.
In addition, since the design element databases S24 and S33 are registered on the production preparation system S30 side and transferred to the basic design system S20, rules and the like for avoiding difficult production parts can be incorporated in the registered contents in advance. Even if the basic design and the production design are divided, the design or production can be performed reliably.
[0090]
In addition, in the design element databases S24 and S33, it can be used in advance because it can be added and registered sequentially by the production design subsystem S31 when “specific parts are not specified” although “registered as rules”. Registration of parts having low characteristics can be omitted, and can be added according to necessity and usage frequency, and the design element databases S24 and S33 can be made compact. 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.
[0091]
(Overall effect of basic design system S20)
The basic design system S20 is composed of the design design subsystem S21, the integration subsystem S22, and the business subsystem S23, thereby efficiently performing operations such as progress management as well as the creation of basic design information W22 including diagram information and integration information. be able to.
That is, by designing the plan view F21, the basic plan view F22, the roof plan view F23, and the wiring diagram F24 by the design design subsystem S21, the elevation view F25 and the perspective view F26 necessary for the meeting with the client S12 can be obtained. Can be created automatically.
[0092]
In particular, in the design design subsystem S21, the basic plan F22, the roof plan F23, and the wiring diagram F24 are basically designed (unit layout, outer shape, floor plan, layout of equipment, etc.). Since the information is automatically referred to, it is possible to save the duplication of operations for the same setting and to easily ensure the consistency and consistency of the design information.
The integration subsystem S22 can automatically create the integration list L21 with reference to the design information of the plan view F21 to the wiring diagram F24, and the work subsystem S23 can estimate the estimate L23 for the client S12, the basic builder S13, and the like. A purchase order L22 for the production preparation system S30 can also be automatically created.
[0093]
(Effect of the plan view section S211 of the basic design system S20)
In the plan view section S211 of the basic design system S20, the unit setting, the entrance setting, and the balcony peripheral setting are sequentially processed to set the frame, and the grid setting, the outer wall setting, and the fitting setting are sequentially processed to set the interior and exterior settings. It can be performed.
[0094]
In particular, in the housing subsection S211A, the entrance setting module S2112 is executed after the basic unit setting module S2111, thereby processing the setting of the entrance part that requires special processing such as dirt and rising walls separately from the unit setting. can do.
For this reason, even if it is a part that should be the entrance, the setting related to the unit of the part can be processed by the unit setting module S2111 of the previous stage in the same way as other parts, or the previous stage for setting the entrance dedicated unit, etc. Inconveniences such as complication of the unit setting module S2111 can be avoided.
[0095]
In the interior / exterior subsection S211B, the grid setting module S2114 can set a grid indicating the reference position on the previously set unit arrangement. 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 or the like.
Furthermore, by providing the outer wall setting module S2115 separately from the fitting setting module S2116 for setting the fitting, it is possible to reliably and easily set the outer wall panel having a large processing difference from the other interior and exterior.
[0096]
(Effects of basic plan section S212 of basic design system S20)
In the basic plan section S212 of the basic design system S20, the area is determined by the basic setting of the foundation and the entrance setting, the normal and special top ends are set, the independent foundation and the auxiliary setting are performed, and the foundation Design can be done.
[0097]
In particular, after the overall cloth foundation is set in the basic setting module S2121, the entrance setting module S2122 is executed, so that the setting of the entrance part that requires special processing such as a dirt floor and a rising fence is separated from the basic setting. Can be processed.
In addition, by setting the overall cloth foundation in the basic setting module S2121 and then executing the independent foundation setting module S2125, it is possible to appropriately set an independent foundation that has presence / absence of installation unlike the cloth foundation. .
For this reason, in the basic setting module S2121, comprehensive and continuous basic setting can be performed without considering the entrance and independent foundation, and automation can be easily promoted by simplifying the processing.
[0098]
Further, after the basic top edge height is set by the top edge setting module S2123, the special top edge setting module S2124 is used to set the top height of a special portion, so that the processing of the top edge setting module S2123 is performed. The special top can also be set reliably.
[0099]
(Effect of roof plan map section S213 of basic design system S20)
In the roof plan section S213 of the basic design system S20, the basic shape of the roof can be set by the roof shape setting module S2131 and the eaves setting and the vertical setting can be set by the subsequent setting setting module S2132.
[0100]
In particular, in the roof shape setting module S2131, a standard program S2133 and a replacement program S2134 are prepared, and by replacing a part of the standard program with a replacement program according to the roof shape, various roof shapes other than the standard can be supported. Compared with the case where a complete execution program is prepared for each roof shape, the program size can be made compact, and maintenance can be improved by sharing a common part.
[0101]
(Overall effect of production preparation system S30)
The production preparation system S30 is configured by the production design subsystem S31 and the order placement / acquisition integration subsystem S32, so that it is possible to efficiently perform operations such as detailed design or production ordering for production.
In particular, by designing in detail the contents set in the basic design information W22 by the production design subsystem S31, the production drawing F30 (parts drawing F31, assembly) required for production at the factory S17 and ordering to the material supplier S16. FIG. F32 and process diagram F33) can be automatically created.
At this time, in the production design subsystem S31, it is possible to separately process the frame and the roof, which are significantly different in processing contents, by configuring the frame production design section S311, the roof production design section S312 and the part production design section S313. Parts used in each can be further processed separately.
The ordering / subtracting integration subsystem S32 can automatically create an integration list L31 with reference to the production drawing F30, and can also automatically create an order sheet L32 for the material supplier S16 and the factory S17.
[0102]
(Effects of manual preparation for production preparation system S30)
In the production preparation system S30, the production design subsystem S31 produces a production manual (process diagram F33) for the relevant parts together with the parts drawing F31 and the assembly drawing F32, thereby making it easy and reliable for the construction work in the factory or on-site. Can be.
In particular, in the production design subsystem S31, manuals corresponding to the parts used in the building are selected and distributed to the factory or the site. Redundancy such as using corresponding manuals can be eliminated, and work can be performed easily and efficiently by reliably supplying the necessary manuals.
[0103]
(Effect of chassis production design section S311 of production preparation system S30)
In the housing production design section S311 of the production preparation system S30, the details of the unit part can be designed by sequentially processing the outer wall panel expansion, standard unit expansion, special unit expansion, and entrance unit expansion. It is possible to carry out detailed design up to the parts that are fitted to the unit or shipped together with the unit by deploying the shipped parts.
[0104]
In particular, by dividing the standard unit expansion module S3112 for processing general standard units from the special unit expansion module S3113 for processing other special units, a large number of standard units are optimized for the unit. By performing the processing, the overall processing efficiency can be increased. On the other hand, the special unit expansion module S3113 can reliably cope with a large number of parameter settings required for the special unit.
[0105]
Further, by providing the entrance unit expansion module S3114 separately from the unit expansion modules S3112 and S3113, the setting of the entrance portion that requires special processing such as the dirt and the rising wall is processed separately from the standard and special unit settings. It is possible to provide a reliable response regardless of whether the unit on which the entrance is formed is standard or special.
Further, prior to the processing of each unit expansion module S3112 to S3114, the outer wall panel expansion module S3111 performs expansion of the outer wall panel that is appropriately attached to each unit, so that a specific outer wall support structure is included in each unit expansion. Detailed design can be done.
[0106]
In the chassis production design section S311, after the unit development described above, the parts to be outfitted in the factory S17 are developed by the body outfitting part development module S3115, and the parts are shipped together with the unit without the outfitting construction by the body shipping member development module S3116. The member to be developed can be developed.
By separating these outfitting parts and shipping members, the main body outfitting parts deployment module S3115 can perform processing in units, and the outfitting shipping parts deployment module S3116 can process members between units in units of buildings. , Reliable processing can be performed.
[0107]
Also, in the chassis production design section S311, the next ordering / subtracting integration sub is created by creating the integration data L31 in the integration data creation module S3117 based on the production drawing F30 developed in each of the modules S3111 to S3116 described above. Processing in the system S312 can be facilitated.
Further, the parts data registration module S3118 can be additionally registered in the above-described design element database S33 as necessary based on the production design information W31 including the production drawing F30 and the integration data L31.
[0108]
(Effect of roof production design section S312 of production preparation system S30)
In the roof production design section S312 of the production preparation system S30, after designing the basic shape of the roof, the detailed design of the roof can be performed by developing the parts of the details constituting the roof shape.
Among these, in the design of the basic shape of the roof, the basic shape of the roof can be obtained by drawing in the roof shape drawing creation module S3122 based on the basic design information W22 input in the roof information input module S3121.
[0109]
Further, the roof panel allocation execution module S3123 can appropriately allocate the roof panels constituting the basic shape of the roof based on the rules registered in the design element database S33.
For this reason, even if the shape of a roof is various, the allocated roof panel can be made into parts which are easy to produce and transport, respectively.
[0110]
These roof information input and roof panel allocation execution processes do not require input of new design information, and can be automatically executed as a series of processes.
The special shape information input module S3124 can reliably perform special processing that cannot be automated or setting of special parts.
[0111]
On the other hand, in the detailed parts development, since the roof panel development module S3125, the joint hardware development module S3126, the vertical part development module S3127, the hut panel development module S3128, and the auxiliary part development module S3129 are shared, they are sequentially or in parallel. Can be processed.
[0112]
In addition, this invention is not limited to the said Example, The deformation | transformation etc. in the range which can achieve the objective of this invention are included in this invention.
That is, in the configuration of the system described above, the format and scale of the computer system to be used may be selected as appropriate in the implementation, and the format and type of the input / output device are the same.
[0113]
In addition, the above-described system on the computer system may be realized based on the functions disclosed in the above-described embodiments using existing computer technology, and a specific algorithm, operation screen, or output information What is necessary is just to select a design etc. suitably.
Further, the specific format and contents of the basic design information W22 and the production design information W31 input / output by the system described above may be selected as appropriate in the implementation, and the same applies to the design element databases S24 and S33.
[0114]
In terms of designing the unit building, it is only necessary to output a drawing, a parts list, and the like necessary for the design, and functions for creating the estimate sheet L23, the order sheet L32, and the like may be omitted as appropriate.
Furthermore, in the said Example, in order to construct a foundation in the field, the foundation plan F23 created by basic design system S20 was sent to the field, but when using a prefabricated foundation etc. which arranges a precast concrete block, a foundation plan is used. F23 may also be sent to the production design system S30 to perform detailed design of the prefabricated foundation parts.
[0115]
【The invention's effect】
As described above, according to the present invention, the basic design for the shape and specifications of the portion that can be seen by the client, the functions requested by the client, etc. In addition to collecting the minimum necessary items that represent the building according to the order, we will produce the production design related to the details and the structure of the parts that the client cannot see, such as the details that correspond to the contents decided in the basic design, Drawings and information necessary for factory production can be compiled.
Therefore, the part where the design change is repeated by the client meeting can be simplified, the work load of the repeated part can be reduced, and complicated production design such as the unit level can be performed only once after the basic design is compiled. It becomes better and can accommodate custom homes that need to be individually designed.
[0116]
In addition, the basic design is mainly an outline design, so even if there is a repetitive work, the load is light and the heavy load design can be avoided. The system can be configured.
Furthermore, by configuring the production preparation system with the production design department and the order placement and integration part, it will be possible to efficiently carry out operations such as detailed design for production or cumulative ordering. It is possible to improve efficiency by processing each category of parts.
[0117]
In particular, in the production design department, the sections of the housing production design, the roof production design, and the part production design are made independent, so that each of them can be processed in parallel, and further efficiency is achieved.
In addition, the integration process can be efficiently and accurately performed by creating integration data when creating each production drawing and using it for integration in the integration section.
[0118]
In addition, the basic design and production design each refer to the common design element database and perform each design based on the common design criteria. This can be avoided, and the amount of information and processing load can be reduced by coding and packaging parts and structures.
Furthermore, in the production preparation system, it is possible to improve the efficiency of construction work or ensure the supply of manuals by creating a production manual for the relevant parts together with production drawings and integration lists.
