Description

  The present invention relates generally to a housing design system, and more specifically to an industrialized custom home design system. More specifically, the present invention relates to a method and system for designing a prefabricated house efficiently and maintaining predetermined quality standards, and calculating and aggregating house components from the designed data without omission.

  The prefabricated construction method is a method of constructing a house by using a member produced in a factory, and there are a wood type, a reinforcing bar type, a concrete type, etc. depending on the difference of the member. In addition, a unit method that produces box-shaped structural units at the factory, so-called units, and combines them at the construction site is a more advanced form of the prefabricated method. In addition, as a classification of construction methods, there is a construction method for transmitting a load by a column or a beam called a frame construction method. However, these methods are not clearly classified and are actually used in combination with their characteristics. These so-called prefabricated house construction is a construction method designed to reduce costs by industrialization, stabilize the quality, and shorten the construction period at the construction site.

  It was always provided as a so-called planning plan in which the specifications of the exterior shape, floor plan, equipment, interior, exterior, etc. of the building were designed in advance by the housing manufacturer. There are various options or pre-prepared variants in the sales of the planning plan, and it is possible to make a certain amount of customer requests using these, but it must be said that it is insufficient.

  In recent years, customer demands have diversified and the level of such demands has increased, and it has become impossible to obtain sufficient customer satisfaction by selling a broad plan. Even in prefabricated construction, various customers A product that can be freely designed to meet the demand is desired. It has become necessary to deal with so-called individual specifications for each customer.

  In the first place, the prefabricated construction method aims at efficient design that ensures quality by omitting the selection from the basic members by pre-standardizing the members or parts used there. Therefore, there should be no need for the act of advancing the design by using the computer and reflecting the customer's wishes in the drawing.

  However, as described above, fixing the floor plan of a house has a problem that even if a plurality of house models are created, all requests for design changes by customers (homeowners) cannot be accepted. In particular, it is common to limit the members (parts) related to the structure and strength of the house.

  For this reason, conventionally, design changes related to members related to strength could hardly be made.

  Among prefabricated buildings using the prefabricated method, the method of assembling and building beams, columns, and outer wall materials, called the steel frame construction method, has a particularly high degree of design freedom in the floor plan, making it easy to reflect customer demands. . However, as the degree of freedom in design increases, it becomes necessary to standardize the types of members and parts and the rules for their combination. For this reason, the trouble of assigning members after determining the plan and picking up the parts for on-site supply becomes excessive, and mistakes and leaks occur frequently.

  Therefore, in view of the above points, an object of the present invention is to automatically draw a floor plan of a house on a display screen and input other information necessary for floor plan design. It is to provide an industrialized house design method and system that can determine all of them.

  The purpose of the present invention is to quickly respond to individual specifications for each customer, conform to the design criteria / rules such as structural calculation, combination of parts, detailed parts, etc. for confirmation of customer specifications, customer specifications and customer conditions. If it is impossible to implement, provide alternatives for customers, inquire about customer changes, accept customer requests, etc., and design the final customer specifications that meet the quality standards set in advance.

  Conventionally, only a floor plan or a construction drawing can be drawn by CAD.

As a result, the time required for the floor plan design can be shortened compared to the conventional case, and the floor plan design can be easily corrected.

  Furthermore, after the floor plan design is performed, the labor for detailed design can be reduced by creating a member list necessary for construction with another CAD.

  In addition, by performing the integration after the floor plan design, an estimate to be presented to the customer can be quickly and accurately created.

  Moreover, since the member information registered in the member information database is verified and registered that satisfies the design conditions, the safety and durability of the built house are ensured.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The present embodiment is a housing design system that supports the design, production, and construction of a variety of fab building according to customer specifications, and FIG. 1 shows an outline of the embodiment of the present invention. The flow of processing is shown roughly.

  This house design system uses CAD and has a basic database. This database is data for defining the design of a prefabricated building having a limited range of degrees of freedom described above, and conversely having a range of degrees of freedom but limited. Although details will be described later, as data defining this limitation, from the member information database DB1 of each member constituting the building and the design information database DB2 defining the design limitation / range / conditions, etc. It is configured.

  The workstation WS1 in FIG. 1 performs verification when registering a new member or the like. More specifically, the workstation WS2 performs prefabricated building design using the member information database DB1, and designs whether or not the member newly registered in the database satisfies a predetermined design quality standard. Verify based on information database design information. If the verification is passed, the input to the member information of the new member is accepted. Further, the design information related to the member, for example, the workstation WS1 has a function of inputting information for limiting the design such as a member name that can be combined. Further, the workstation WS1 performs maintenance for predetermined design information or inputs additional conditions for new design conditions, etc., inputs additional information for design support, and registers in the design information database DB2, and further inputs them. It also includes a function to check information and verify that the information is in accordance with a predetermined purpose. This part has an important role of checking the quality of newly registered members of the building being designed.

  The workstation WS2 (another CAD according to the present invention) uses the above-described member information database and design information database to advance the floor plan design of the prefabricated building and the layout design of the parts and members. In designing at the workstation WS2, the designer draws a floor plan on the display screen, and performs architectural design by selectively using the members registered in the member information database DB1. This operation is basically based on selecting one of the options presented by the member information database and the design information database (hereinafter, these two are simply referred to as a database DB). However, since there are a large number of members that make up a house, when a designer makes a new entry, input support such as automatic entry into a member record with initial values defined in the design information database is performed in advance. ing. In this workstation WS2, in addition to proceeding with the design of the building, it analyzes the strength etc. based on the structural calculation results of the prefabricated building, displays each analysis process, and finally determines the structural calculation results In addition to the structure calculation P2 function for outputting the design, the design of the designed building shown in FIG. 2, such as the floor plan F1, the exterior view F2, the plan view F3, etc. A list L1, an estimate L2, a cost composition table L3, and the like. As described above, the workstation WS2 has a function of designing a part by arranging a building for each house.

  The building description data D1 indicating the design contents of each residence designed at the workstation WS2 is sent to the workstation WS3. The workstation WS3 uses the database DB to create a construction drawing from various data such as building shape and member information included in the building description data D1 for each residence, and to create a member list for final ordering. To do.

  Here, although the member information database DB1 is used in both the workstation WS2 and the workstation WS3, there is a member (referred to as a detailed member) that is not directly related to the design quality or the structural calculation in the floor plan design for each house. In FIG. 3, detailed members are used as batch member information. In WS3, detailed members are expanded into a plurality of records, and registered information is used. That is, the building description data D1 for each house is specified as a data record by developing detailed members into individual members at the workstation WS3. For example, things such as rain gutters are developed at this stage into individual parts, attachment parts, or the number of gutters of a predetermined size, depending on the final confirmed roof shape of the house. The finally developed member information for each house is collected as an order member including the member information included in the building description data for each house, and the order list extracted by the member list L11 shown in FIG. Lists L21 and L22 are created and output.

  The workstation WS3 has functions required in the production member preparation stage, and performs the above-described member integration and order sorting, and at the same time creates and outputs a drawing F4 for construction, which is different from the drawing output by the workstation WS2. Have the ability to In this example, an example of an electrical wiring diagram is shown as a construction drawing F4 with respect to the floor plan F1 in FIG. Other examples include a water supply / drainage piping diagram, a gas piping diagram, or a diagram showing a structure of a column-structured column beam. The figure output here is a figure for construction, and generally there is a deformed part in part.

  Each of the sorted member information L21 can be viewed by each ordering party via a publicly available communication network WEB. In this case, it is a matter of course that necessary information can be presented only to the necessary ordering party by defining the relationship between each ordering party and the information to be browsed using the identifier (ID). In addition, outsiders can be prevented from browsing by using a password. This browsing has a meaning like provisional ordering, and the ordering party can obtain information on ordering in advance. The sorted member information L22 can also be faxed to the supplier. In this case, it is unidirectional by making it possible to browse by each supplier through the communication network WEB. As a result, the communication between the two-way orderer and the supplier is kept in good condition, and the procurement period Expected to help shorten.

  Among the database DBs, regarding the member information database DB1, as described above, there is some difference between the member information used in the design stage and the member information used in the production member preparation stage. It is related to the division of roles.

  The role of the workstation WS2 is to design customer specifications, desired specifications, ie, the layout of the house and its necessary parts / members (strength design, etc.) and their arrangement, and with predetermined limited conditions and with predetermined quality The purpose is to verify that the building can be built according to the standards. The role of the latter workstation WS3 is to actually create a building with the actually verified specifications. In other words, the former shares the part related to the customer specification, and the latter shares the part not directly related to the customer specification, that is, the part related to the pre-designed or prepared member that the customer does not need to be aware of. .

  Here, the member information is information on the member itself, for example, name, product name, product number, model number, material, shape, dimension, processing data, strength data based on structural calculation, weight data, joining data based on the allocation of members, Price, delivery date, manufacturer, agency, etc. are included. The same applies to the members that are set as collective information, and the same applies to the members that have been developed.

  Therefore, the design information database DB2 is design information related to the members used by the workstation WS2 as described above, and also related to the members as described above. By selecting limited material information, it is not possible to deal with problems such as building strength or construction constraints. In addition, it supports the design progress for designers against such problems, and the design itself. This is necessary when the design is completed efficiently and with predetermined quality standards. Such information is created and stored by referring to past results as design information or by verifying in advance.

  Here, the floor plan design for each residence by the designer is started by inputting the building shape and the floor plan. In the progress of this design, details are determined with reference to design information and member information. At this time, the mutual relationship between the design information and the member information in the progress of the design is related with an identifier representing a concept that mainly defines the use purpose of the space as a “part”. This part may or may not be inevitably determined from the spatial relationship of the building. In the latter case, the designer designates the part that is in the process of design progress. . For example, in the case of a floor plan on the second floor, a floor or a part such as a colonnade is designated for a certain room space. Using this “part” category, as shown in FIG. 1, each information in the design information database and the member information database is related, and while using these information, it is limited each time. The design will be completed under certain conditions. Of course, the association with the operation of the designer's workstation WS2 is also associated with this part, and the design limitations, scope, and conditions are specified according to the drawing of the floor plan of the designer and the structure designation operation. Thus, it is possible to support the appropriate database base DB1 or DB2.

  This limited condition includes a limitation by a member, for example, a length related to the member, a limitation by design information, for example, “add a beam for reinforcement when a veranda is provided in contact with a blow-off” as described later. There is a limitation on the relationship between the blow-by as the part and the veranda as the part. In this case, a part of a certain structure is defined as a veranda according to a designer's instruction. In the actual case, attaching a veranda is a customer specification and there is a means to satisfy this specification, so the veranda is placed at that position after reinforcing the beam.

  FIG. 4 is a diagram showing such an example. This FIG. 4 shows a part of the floor plan of the prefabricated house, and the pillars H3, H4, H5, H6 (here, the ■ marks in the figure are not necessarily pillars, but points on the design screen of the workstation). The portion surrounded by () is a colonnade. The part of this part is preset by the designer to be an atrium. The case where the part B2 surrounded by the points H1, H2, H4, and H3 in contact with the columns H3 and H4 on the outside of the blowout is arranged as a veranda is shown. In this case, when the designer operates the workstation WS2 to draw the floor plan of the veranda on the display screen, the design information database DB2 associated with the veranda is referred to. The CAD program determines whether or not the condition should be applied based on the addition of the veranda based on the information on the design limitation described above. The CAD program determines that it is necessary to reinforce the beam in this example, and automatically reinforces the space between the columns that are in contact with the atrium space. On the other hand, the same applies to the case where, after the veranda is arranged, the area adjacent to the veranda (the area indicated as blow-in in FIG. 4) is set as blow-by. However, in the example shown in the figure, a reinforcing beam is already provided, and if it is confirmed that the strength is sufficient, no further beam reinforcing measures are taken.

  In the example shown in FIG. 4, the designer does not need to be involved in measures for satisfying the design conditions. However, there are cases where the designer is involved and it is possible to avoid limitation by design information. In either case, since it is permitted under certain conditions, in this example, the in-place placement of the veranda is not rejected. If it is not conditional, it is displayed that setting is impossible after setting, so that it is not possible to proceed to the next design.

  Here, regarding the veranda, a case where the dimensions of the depth dimension points H1 and H3 are set will be described. First, the designer sets an area for placing a veranda on the workstation WS2. Then, by designating the part as a veranda, information indicating the veranda as a part is sent to the design information database, and here, candidate member information usable for the veranda is guided on the workstation WS2. The designer selects one that matches the customer's specifications from the guided candidates. The shape of the selected member information is extracted from the database, and the set area is changed to a size indicating the shape of the member. If another candidate is selected at this time, it will change to the shape of the selected member. In this way, the designer is only given the freedom to select a member that fits the desired dimensions from the proposed member candidates, and ultimately the dimensions of points H1 and H3 are defined by the members. The dimensions on the workstation screen are set to the dimensions of the selected member. The design can proceed in this way. The above example shows that the design progresses while receiving the limitation by the design information and the limitation by the member information.

  FIG. 5 illustrates a part of the plan view of the building in the same manner as FIG. 4, and shows a recess in the wall surface of the building. In this figure, the ■ mark indicates the position of the column as well as the point. H11 and H12 are protruding corner pillars. H13 and H14 indicate the corner pillars. In this case, since the hatched portion is a portion that has already been defined, H13 and H14 are recognized as corner columns from the shape analysis of the building. The design itself can be advanced to such a structure. This is because the building itself should not be a problem. However, when confirming the final building structure and the like, the interval between the two corner pillars is checked due to construction restrictions. This is because it is necessary to build a scaffold during construction, and a scaffold cannot be built if the distance is short. In this case, when this distance is smaller than a predetermined dimension, the design cannot be continued. If this happens, it can be avoided by changing the dimensions of this part.

  As explained above with examples, the contents in the design information database are not limited to simply determining whether or not to join / combine members, specifying conditions, but also to interference and construction caused by the spatial arrangement of members. It also includes defect information generated by the method, and it is possible to determine whether or not the building is possible and specify the member at the design stage.

  As described above, to summarize, in prefabricated architecture, (a) a part having a degree of freedom of design, for example, floor plan design, and (b) a part having a degree of freedom to select, for example, selection of walls and flooring ( c) Parts that do not have any degree of freedom, for example, frame members such as columns and foundations, and parts that are concerned only in construction without regard to the strength or quality of the building in design, such as rain gutters, waterproofing, heat insulation, etc. There are wood construction members such as exterior materials, partitions, and walls. From another viewpoint, there are (a) a customer specification part, (b) a predetermined part not directly related to the customer specification, or a part that is automatically determined and manufactured based on the customer specification.

  In other words, there is a design part for “quickly responding to individual specifications for each customer” as described above, and a design and manufacturing part for “calculating and consolidating the components that make up a house efficiently and without omissions”. I understand. The former design part is a stage in which the part (a) described above is determined and the part (b) is selected. And, in the production member preparation stage before shifting to the on-site construction, the part (c) is combined. The part (c) is called a detailed member. Although it is not necessary for the detailed member, the design for “quickly responding to individual specifications for each customer” at the final stage of (a) and (b), it is essential at the stage of constructing the building on site. For example, rain gutters need to be allocated according to the shape of the roof based on the frame shape determined by the individual floor plan design (for each part such as a corner in a corner, or by the length of the flat part). By determining the above rules, this is one example where the designer does not need to design each one. Therefore, in the embodiment of the present invention, the part (c) is separately collected and aggregated for the design of “quickly responding to individual use for each customer” separately from (a) and (b). Data is retained. After confirming (a) and (b), at the production preparation stage before moving to on-site construction, perform detailed allocation by a method determined in advance using the data of (c), determine individual members, and deploy Has been. Then, based on this data, member integration or order sorting is performed.

  In addition, by confirming the part (a) described above, selecting the part (b), and combining the part (c) with these, in each item, between items, or a combination thereof, In order to meet the established quality standards and build with a certain construction method, rules to be observed are required. Furthermore, in order to link these rules to the progress of the design work and to further work efficiently, in the embodiment of the present invention, in addition to the creation of the rules described above, these rules and the design work are linked. The connector is created and used with the concept of “part”. The design information database shown in FIG. 1 is attached with the design rule described above and a connector based on the part, and the member connector of the part is associated with individual member information data in the member information database related thereto. Includes data. The support of the database DB for the workstation WS2 is basically performed based on a connector by this part.

  The design by the workstation WS2 basically includes the steps shown in FIGS. FIG. 6 shows the limitation by design information, and FIG. 7 shows the limitation by design information.

  FIG. 6 shows a typical design work flow in the middle of the design. In order to proceed with the design in step S62, the part (location) of the building diagram (floor plan) is designated on the screen of the workstation WS2, and This is the stage where the designer manipulates the content. In response to the operation of the designer, candidates relating to the operated part at the position are presented (step S63). In this step, when a window is set in a part of the building map operated by the designer, the designer sets the position operated by the designer as a “window”, and the designer operates The case where the part is automatically set only from the position is also included. Here, in either case, design information finally associated with the concept of the part is called from the design information database, and with the support of this information, candidate member information is extracted from the member information database, and workstation WS2 Displayed on the screen. In step S64, the designer selects one from the presented candidates. Regarding this candidate presentation, for example, regarding window members, the width of the window, the presence and type of shutter, the type of glass, etc. are guided hierarchically according to each member, and a series of selections are made by selecting each time. This completes the settings for windows.

  FIG. 7 also shows a typical design work flow in the middle of the design in the same way as FIG. 6, and when a certain operation is performed on a part (place) of the building diagram on the screen of the workstation WS2. The following flow is shown. In step S72, design information related to the above-described operation part based on the concept of the part is read from the design information database, and guidance or design conditions or limiting conditions are presented on the screen of the workstation WS2. The In step 73, the designer performs design or setting in accordance with the presentation. The program verifies whether the design or setting matches the design information presented or associated. If it is determined in step 74 that the verification results match, the process can proceed to the next new design step. If the verification results do not match, the process returns to step S72.

  By proceeding with the steps as described above, the design satisfying the two limiting conditions of the limitation by the members themselves, the limitation by the combination of the respective members, that is, the limitation by the design information is completed. At this stage, the design that makes the best use of the limited degree of freedom as a so-called prefabricated building has been completed. However, even in such a design, it is necessary to perform a structural calculation, which is the maximum quality confirmation as a building, to confirm the building strength, the constraints on construction, and the like. This structural calculation can be said to be limited by a comprehensive combination of members. This structural calculation confirmation program includes strength calculation and confirmation of construction constraints. In the strength calculation, the calculation results are mainly shown for beams and columns, and the final judgment results for the entire building are shown. When the final determination result is “No”, the design is corrected with reference to the calculation results of the columns and beams. As the final judgment result, “Yes” is judged and the program confirms that each calculation result has been confirmed by the designer. It is stored in a single file as descriptive data and passed to the workstation WS3.

  Therefore, in the embodiment of the present invention, the design is performed by (1) limitation by members, (2) limitation by design rules, and (3) confirmation by structure calculation. As a result, the design for “quickly responding to individual specifications for each customer” in the prefabricated house is completed. After the completion, from the floor plan F1 shown in FIG. 1 for presentation and confirmation to the customer, the building exterior view F2, the specification L1 describing the selection of exterior materials, interior materials, fittings, equipment, etc., and the design data Output of various design drawings such as estimate sheets, cost composition tables, layout drawings, and external views created by integration is performed.

  As described above, the data input and maintained by the workstation WS1 is designed to satisfy customer specifications in a limited form of prefabricated construction, and more efficiently shared between the workstations WS2 and WS3. Is in an important position.

  To summarize the present invention, in one expression, whether or not there is a degree of freedom in prefabricated construction is defined by members and design information, and the design is performed under these prescribed conditions. Records are developed in stages and stored in building description data for each house. The data in the database in such a system is associated with the concept of the part as the data required by each part, and from design to production member order The member is determined according to the part stage. In other words, the members that are not related to the free design for the customer are characterized by the fact that they are organized and aggregated, associated with the parts at the customer plan design stage, and handled as collective data without being developed in detail. From another viewpoint, the data of the member information database and the design information database are associated with each other based on the concept of the part.

  As described above, in the present embodiment, when inputting the member information database and the design information database, not only a means for inputting but also a means for confirming and verifying the input data, it is possible to ensure data consistency.

  Information on each member is organized and stored in the member information database, and information on various guidance displays, condition presentations, and judgments when the member is used is organized and stored in the design information database. In addition to simply selecting a member, it can be confirmed that the selected member is available.

  The contents in the design information database are not limited to simply determining whether or not the members can be joined, but also include interference caused by the spatial arrangement of the members and failure information caused by the construction method. It is possible to specify. Such a determination is based on an individual member, but if it is simply considered as a combination of individual members, a determination on an explosive combination is required. On the other hand, a realistic processing amount is obtained by organizing combinations by meaning and association based on the concept of “part” and performing only necessary determination.

  In addition, customer-specific design and other types such as factory-specific design or design related to factory specification, construction specifications, etc. are separated, and the former design range is limited to the required range. Since the design information is created and associated with the concept of the part including the design operation, the size of the associated database is also realistic, and the database can be easily maintained and managed.

  Since the member information related to the building, the information related to the shape, the designation information related to the interior finish, etc. are comprehensively stored, the member integration can be performed in detail and the estimation can be performed with high accuracy.

  Since material integration is possible in detail, the basic data for production instructions and material ordering are accurate.

  Since the various member arrangements and shape data are accurately stored up to the position information, it can be used as a construction drawing simply by processing the output into a format that is easy to see.

  Consistency with the current system when new members are assumed because various member data and design data are organized and stored, and a program group for determining consistency between new members and previous members is included. It is also possible to inspect.
