Description

  The present invention relates to a building plan analysis system that analyzes a building plan for each house using a database for each house that collects and stores data such as basic specifications of buildings, exterior fittings, interiors, equipment, and approximate building prices. It relates to a building plan analysis method.

  In general, a design drawing is created by using a CAD (Computer Aided Design) system. For example, if shape data of each room and interior material of a house is created by a CAD system, the inside of each room can be displayed on a computer screen. Moreover, if the CAD system is used, the construction cost of the house can be calculated based on the created design drawing.

  Thus, in the past, construction costs were estimated based on design drawings created with a CAD system or the like. For example, if the estimated amount does not match the user's budget, the design can be changed by changing the floor plan. There was a complication that had to be recreated. On the other hand, there is also a request from the user side to easily estimate the construction cost at a stage where the detailed layout of the house is not decided, so the development of a simpler estimation method that does not depend on the design drawing is required. It was requested.

  Therefore, the present applicant has already proposed a construction cost estimation method capable of easily estimating the construction cost of a building such as a house in a short time (see, for example, Patent Document 1).

In this construction cost estimation method, the display means displays a plurality of types of building types of the building to be built stored in the storage means, and an appropriate one of the plurality of types of building types displayed by the selection means. A step of selecting a building type, a step of displaying a plurality of room types of the building stored in the storage unit, and a step of selecting each floor of the building from the plurality of room types displayed by the selecting unit. A step in which an appropriate room type is sequentially selected, a step in which a room size is input for each selected room type by the input means, and a calculation means in which the selected building type and selection are selected. A step of calculating a construction cost of each room and a construction cost of the building based on the type of each room entered and the size of each room inputted, and a display means,
Displaying the calculated construction cost of each room and the construction cost of the building.

By such a construction cost estimation method, for example, as shown in FIG. 13, the estimated amount for each item such as main construction is displayed in a list format, the total amount is in the region r, and the unit price is in the region s. It is displayed.
Japanese Patent No. 3407602

  According to this method, the construction cost of a building such as a house can be estimated easily in a short time. However, only the estimated amounts in the list form shown in FIG. 13 are displayed. For customers who are amateurs of construction, whether the estimated amount is appropriate or not, the overall amount balance is appropriate. There was a problem of not knowing the specific characteristics of the building, such as whether it is, which part is expensive compared to the standard plan or other mansions, and which part is reduced . For example, in the estimate shown in FIG. 13, the amount of money is displayed collectively as the main body construction. For example, the amount of the main body construction is disclosed (specifically, the balance of the amount of the housing construction, the external construction, the internal construction, and the equipment construction). If it is possible to understand at a glance, it becomes possible for amateur customers to grasp the balance of the amount of money for the main construction sensuously. If you know not only the amount of money but also the structural characteristics of the building, such as whether the storage area ratio to the floor area is more or less than that of the standard plan or another person's mansion, the building It can be used as a reference when designing.

  The present invention was devised by paying attention to such a point, and the purpose of the present invention is to display the features on the amount of money and the structural features of the building subject to the estimation in a visually easy-to-view state. A building plan that allows customers to easily understand the characteristics of a new building and provides sales representatives with accurate advice on the characteristics of the building. An analysis system and a building plan analysis method are provided.

A selection means for selecting one residence as an analysis target residence, and an arbitrary item is selected from a plurality of analysis items for the selected analysis target residence. Thus, the data of the item is extracted from the data of all houses stored in the house database, and the extracted house data is plotted on the graph to plot the analysis object house. And a display means for displaying the display differently in other residences.

  According to the present invention having such a feature, it is possible to visually confirm the comparison of the building for which the approximate building price is calculated with other buildings by item as well as the overall estimated price.

  In this case, the other house includes data of a standard plan of a building prepared in advance. Therefore, it is possible to compare the building for which the approximate building price has been calculated with the standard plan, so it is also necessary to visually confirm what kind of difference the building simulated by the customer's request is from the standard plan. Can do.

  Here, the analysis items include at least one of the outer circumference length, the number of corners, the roof area, the roof balcony area, the sash amount, the storage area, and the partition length. It is displayed. Thus, by setting the structural features of the building as an analysis item, it is possible to visually confirm a comparison between the structure of the building simulated by the customer's request and the structure of the building of another residence. For example, when the ratio of the outer peripheral length to the floor area is larger than that of other residence buildings, it can be seen that the building simulated according to the customer's request is an uneven structure as a whole in plan view. Further, when the ratio of the storage area to the floor area is smaller than that of other residences, it can be seen that the building simulated by the customer's request is a building with less storage capacity than the other residence buildings.

  In addition, the building plan analysis system of the present invention analyzes the building plan for each house using a database for each house that collects and stores data such as basic specifications of buildings, exterior fittings, interiors, equipment, and approximate building prices. The building plan analysis system that performs the above-described selection means for selecting one residence as an analysis target residence, and by selecting an arbitrary item from among a plurality of construction items for the selected analysis target residence, Extraction means for extracting the data of the item from the data of the analysis target house stored in the database according to the house, and display means for dividing the extracted data of the analysis target house into construction types and displaying the figure It is characterized by that.

  Here, the construction type is a balance of construction costs. The graphic display is preferably a pie chart. Specifically, the breakdown of the estimated building price is displayed in a pie chart as the price ratio of each of the frame work, external work, internal work, and facility work. As a result, the customer can easily visually grasp the overall balance, such as which work is the most expensive and which work is important.

  In addition, the building plan analysis method of the present invention analyzes the building plan for each house using a database for each house that collects and stores data such as basic specifications of buildings, exterior fittings, interiors, equipment, and approximate building prices. The building plan analysis method for performing a selection step of selecting one residence as an analysis target residence by the selection means, and arbitrarily selecting from a plurality of analysis items displayed on the display means for the selected analysis target residence When the item is selected, an extraction step for extracting the data of the item for each residence from the data of all residences stored in the database for each residence, and plotting the extracted data for each residence on a graph And a display step of displaying on the display means with different display forms for the analysis object house and the other house.

  According to the present invention having such a feature, it is possible to visually confirm the comparison of the building for which the approximate building price is calculated with other buildings by item as well as the overall estimated price.

  In addition, the building plan analysis method of the present invention analyzes the building plan for each house using a database for each house that collects and stores data such as basic specifications of buildings, exterior fittings, interiors, equipment, and approximate building prices.

<Embodiment 1>
FIG. 1 is a functional block diagram showing Embodiment 1 of a building plan analysis system of the present invention.
The building plan analysis system of Embodiment 1 takes an independent form as a system.

  That is, a general-purpose computer 1 for calculating the approximate building price of the building and analyzing the building plan is provided. The computer 1 includes an input device 2 such as a mouse and a keyboard for inputting various data, a CRT, an LCD, and the like. Are connected to a display device 3, a storage device 4 such as an HD (hard disk), and an output device 5 such as a printer.

  The computer 1 includes a CPU that is a central processing unit, and ROM and RAM that are storage units. The ROM stores a control program for controlling the operation of the entire system. Various programs such as calculation of construction cost estimation of a building desired by a user and plan analysis (aggregation) processing of a building simulated by a customer's desire are included. Execute the process. The RAM is a memory that functions as a work area when the control program is executed, and temporarily stores programs and data necessary for executing the control program.

  The storage device 4 stores data necessary for construction cost estimation, such as basic building specifications, external fitting specifications, interior specifications, equipment specifications, types and unit prices of each material / member, construction unit price, etc. in a file format. Yes. Further, the storage device 4 also stores a database for each house that collects and stores data such as basic specifications of buildings, exterior fittings, interiors, facilities, and approximate building prices that are simulated according to customer requirements.

-Explanation of the calculation process of approximate building price
In the building plan analysis system having the above-described configuration, first, a calculation process of the approximate building price of a building simulated according to the customer's request will be briefly described. The basic point of this calculation process is described in detail in Japanese Patent No. 3407602 already proposed by the present applicant, and will be briefly described here.

  First, a plurality of types of buildings to be built stored in the storage device 4 are displayed on the display device 3. When a user (for example, a sales representative) selects an appropriate building type from among the plurality of displayed building types by using the input device 2, the display device 3 stores the building stored in the storage device 4. Multiple room types are displayed. The sales person in turn selects the appropriate room type for each floor of the building from the displayed room types using the input device 2 and sets the room size for each selected room type. When input, the computer 1 calculates the building cost of the building based on the selected building type, the type of each selected room, and the size of each input room, and displays the calculated building on the display device 3. Display construction costs. An example of the display result is shown in FIG. 13, and the estimated amount for each item such as main construction is displayed in a list format. The computer 1 stores all data including the estimated building price calculated in this way and the simulated building structure in the database of each house in the storage device 4.

  In this way, the computer 1 simulates the approximate building price for each residence of various customers, and accumulates all the data in the residence database each time. As a result, all the data on the structure of the building including the estimated building price is stored in the residence database for each customer residence.

-Description of building plan analysis processing according to the present invention-
In the building plan analysis, data on the structure of the building including the approximate building price accumulated for each house as described above is used.

  First, one residence is selected as an analysis target residence by the input device 2. Here, the building for which the approximate building price is calculated by the above simulation is selected as the analysis target residence of the building plan.

  Then, the plan analysis screen 100 shown in FIG. 2 is displayed on the screen of the display device 3. In the plan analysis screen 100, tags of selectable analysis items are prepared at the top of the screen. In this example, there are seven items: "peripheral length ratio", "protruding corner ratio", "roof area ratio", "roof balcony area ratio", "sash amount ratio", "storage area ratio", and "partition length ratio" Is prepared. The sales representative selects one analysis plan from these. However, this item is an example, and can be increased or decreased as necessary. Below this tag is a display screen 101 for displaying the analysis result. In this display screen 101, the floor area is assigned to the horizontal axis, and the item selected from the tags is assigned to the vertical axis. Also, under the display screen 101, information on the own property that is the analysis target house is displayed, and a comment field 102 is displayed on the right side of the information on the own property. The comment field 102 is a presentation screen for sales promotion to the sales person when the sales person uses this system. When the sales person uses the system while showing it to the customer, advice to the customer is given. It becomes a screen to display. Here, the explanation is given as a presentation screen for the sales staff.

Here, when the sales representative selects, for example, “peripheral length ratio” (specifically, when the cursor is moved to “peripheral length ratio” and clicked), the computer 1 stores data on the outer peripheral length in the residence. It extracts from the data of all houses stored in another database, and plots the extracted data for each house on the graph of the display screen 101. FIG. 3 shows a plan analysis screen 100A at this time. That is, an outer peripheral length ratio is assigned to the vertical axis of the display screen 101A, and the outer perimeter of the floor area of all the residences stored in the residence database is matched with the values on the vertical and horizontal axes. The length ratio is plotted (indicated by □ in FIG. 3). In addition, on this display screen 101A, the perimeter length ratio with respect to the floor area of the standard plan (in this example, two types of type 1 and type 2) stored in advance in the house database is also superimposed as bar graphs 101A1 and 101A2. Is displayed. Then, a total plot of the perimeter length ratio with respect to the floor area of the whole residence and the bar graphs 101A1 and 101A2 of the standard plan are displayed on the screen, and the perimeter length ratio with respect to the floor area of the building simulated by the customer's request Is plotted 101A3 (indicated by ◇ in FIG. 3). In this example, the building of the plan analysis target has a floor area of 122 m ² and an outer peripheral length ratio of 0.52, which is almost the same ratio as other residences and standard plans. That is, it can be seen that the building simulated according to the customer's request has a standard appearance in the uneven shape on the outer periphery.

Similarly, when the sales representative selects “exit corner ratio” from the tag of the display screen 100 shown in FIG. 2, the computer 1 stores data relating to the exit corner ratio in all residences stored in the database. The data for each house is extracted and plotted on the graph of the display screen 101. FIG. 4 shows a plan analysis screen 100B at this time. That is, the vertical axis ratio of the display screen 101B is assigned with the ratio of the number of corners, and the area corresponding to the numerical values of the vertical axis and the horizontal axis corresponds to the floor area of all the houses stored in the house database. The ratio of the number of protruding corners is plotted (indicated by □ in FIG. 4). The display screen 101B also has bar-shaped graphs 101B1 and 101B2 for the ratio of the number of corners to the floor area of a standard plan (in this example, two types, type 1 and type 2) stored in advance in the database by residence. Overlaid. Then, on the screen on which the total plot of the ratio of the number of corners with respect to the floor area of the entire residence and the bar charts 101B1 and 101B2 of the standard plan are displayed, the output of the building simulated for the customer's request with respect to the floor area is displayed. The corner ratio is plotted (indicated by ◇ in FIG. 4) 101B3. As described above, in the first embodiment, the display forms of the symbols to be plotted are different between the analysis target residence and the other residences. In this example, the building of the plan analysis target has a floor area of 122 m ² , has 13 corners, and has a corner ratio of 0.11. It can be seen that this is about the same ratio as other residences and standard plans. That is, the building simulated according to the customer's request has a standard appearance in the uneven shape on the outer periphery.

Similarly, when the sales representative selects “sash amount ratio” from the tag of the display screen 100 shown in FIG. 2, the computer 1 stores data relating to the sash amount ratio in all residence data stored in the database for each residence. And the extracted house-by-house data is plotted on the graph of the display screen 101. FIG. 5 shows a plan analysis screen 100C at this time. In other words, the sash amount ratio is assigned to the vertical axis of the display screen 101C, and the area corresponding to the numerical values of the vertical axis and the horizontal axis corresponds to the floor area of the entire house stored in the residence database. The amount ratio is plotted (indicated by □ in FIG. 5). In addition, on this display screen 101C, the ratio of the sash amount to the floor area of the standard plan (in this example, two types of type 1 and type 2) stored in advance in the database according to the residence is also superimposed as bar graphs 101C1 and 101C2. Is displayed. The sash amount with respect to the floor area of the building simulated as desired by the customer on the screen on which the total plot of the ratio of the sash amount to the floor area of the entire residence and the bar graphs 101C1 and 101C2 of the standard plan are displayed. The ratio is plotted (indicated by ◇ in FIG. 5) 101C3. In this example, the building of the plan analysis target has a floor area of 122 m ² , the sash amount for this is 1,043,500 yen, and the sash amount ratio is 8,553 yen. It can be seen that this is a lower price than other residences and standard plans.

Similarly, when the sales representative selects “storage area ratio” from the tag on the display screen 100 shown in FIG. 2, the computer 1 stores data relating to the storage area ratio in the data for all houses stored in the database for each house. And the extracted house-by-house data is plotted on the graph of the display screen 101. FIG. 6 shows a plan analysis screen 100C at this time. In other words, the storage area ratio is assigned to the vertical axis of the display screen 101D, and the storage for the floor area of all the residences stored in the database for each residence is located at a location that matches the values on the vertical and horizontal axes. The area ratio is plotted (indicated by □ in FIG. 6). In addition, on this display screen 101D, the ratio of the sash amount to the floor area of the standard plan (in this example, two types of type 1 and type 2) stored in advance in the database according to the residence is also superimposed as bar graphs 101D1 and 101D2. Is displayed. Then, on the screen on which the total plot of the storage area ratio to the floor area of the entire residence and the bar graphs 101D1 and 101D2 of the standard plan are displayed, the storage area with respect to the floor area of the building simulated as desired by the customer The ratio is plotted (indicated by ◇ in FIG. 6) 101D3. In this example, the building plan analyte floor area is 122m ^2, a storage area of 18.6 m ² to this, storage area ratio becomes 0.16. It can be seen that this is a larger storage capacity than other residences and standard plans. That is, it can be seen that the customer simulated the building with an emphasis on storage capacity.

  In the above description, the shapes plotted on the display screen are distinguished from each other. However, different shapes may be given to the shapes plotted on the display screen. For example, as shown in FIG. 3, a plot of the ratio of the perimeter length to the floor area (indicated by □ in FIG. 3) is displayed in red, and the ratio of the perimeter length ratio to the floor area of the building simulated as desired by the customer It is possible to display the plot (indicated by ◇ in FIG. 3) in yellow and the standard plan bar graph in blue or green. The same applies to FIGS. 4 to 7.

  Further, in the building plan analysis system according to the first embodiment, not only the above-described plan analysis on the structure of the building but also the balance analysis of the construction cost can be performed. Hereinafter, the balance analysis of construction costs will be described.

  In the balance analysis of the construction amount, the balance of each construction amount is displayed on the display device 3 based on the main construction data (the price shown in the main construction budget column shown in FIG. 13) of the estimated building price calculated earlier. Is displayed. FIG. 7 shows a balance analysis screen 200E displayed at this time. On the left side of the balance analysis screen 200E, the breakdown of the main body work is represented by a pie chart as the price ratio (%) of the frame work, external work, internal work, and facility work. Further, the right side of the screen is a screen for displaying the details.

  Here, when the sales representative selects, for example, “frame construction” (specifically, when the cursor is moved to “frame construction” and clicked), the computer 1 stores data related to the frame construction in the database by residence. Is extracted from the data of the house to be analyzed stored in, and the extracted data is also displayed as a pie chart on the right side of the balance analysis screen 200E. FIG. 8 shows a balance analysis screen 200F at this time. That is, on the right side of the screen, the breakdown of the frame construction is shown as a pie chart with the price ratio (%) of the frame and the foundation. In this way, by displaying up to the price ratio of the foundation and the housing, it becomes possible to know in more detail the structure of the building simulated by the customer's request.

  Similarly, when the sales representative selects, for example, “external construction” on the balance analysis screen 200E shown in FIG. 7 (specifically, when the cursor is moved to “external construction” and clicked), the computer 1 Then, the data related to the external work is extracted from the data of the analysis target house stored in the database according to the house, and the extracted data is also displayed on the right side of the balance analysis screen 200E as a pie chart. FIG. 9 shows a balance analysis screen 200G at this time. That is, on the right side of the screen, the breakdown of external work is shown as a pie chart with the price ratios (%) for external openings and incidentals, exterior exterior walls and incidentals, and roofs and incidentals. Thus, by displaying the price ratio of the external opening / attachment, exterior exterior wall / attachment, roof / attachment, it becomes possible to know the structure of the building simulated according to the customer's request in more detail.

  Similarly, when the sales representative selects, for example, “internal work” on the balance analysis screen 200E shown in FIG. 7 (specifically, when the cursor is moved to “internal work” and clicked), the computer 1 The data relating to the internal work is extracted from the data of the analysis target house stored in the database according to the house, and the extracted data is also displayed on the right side of the balance analysis screen 200E as a pie chart. FIG. 10 shows a balance analysis screen 200H at this time. That is, on the right side of the screen, the breakdown of internal work is shown as a pie chart with the price ratios (%) for storage, construction, ancillary, internal joinery, interior finishing, and insulation and interior basement. In this way, by displaying up to the price ratio of storage / manufacturing / accompaniment, interior fittings, interior finishing, thermal insulation / interior base, it becomes possible to know in more detail the structure of the building simulated by the customer's wishes.

  Similarly, when the sales person selects, for example, “facility construction” on the balance analysis screen 200E shown in FIG. 7 (specifically, when the cursor is moved to “facility construction” and clicked), the computer 1 Then, data related to the facility construction is extracted from the data of the analysis target house stored in the database according to the house, and the extracted data is displayed in the same way as a pie chart on the right side of the balance analysis screen 200E. FIG. 11 shows a balance analysis screen 200I at this time. That is, on the right side of the screen, the breakdown of facility work is shown as a pie chart with the price ratio (%) for indoor water supply / drainage hot water supply equipment, bathroom equipment, kitchen equipment, sanitary equipment, ventilation equipment, information equipment, and electrical equipment. . In this way, by displaying up to the price ratio of indoor water supply / drainage hot water supply equipment, bathroom equipment, kitchen equipment, sanitary equipment, ventilation equipment, information equipment, electrical equipment, it is possible to know in more detail the structure of the building simulated by the customer's request It becomes possible.

  In the balance analysis of the construction cost, the construction items are written in letters in the pie chart, but in addition to this, different colors may be given in the pie chart to distinguish them more clearly.
